    专利说明:

    [0001] The present invention relates to a resealable container for consumer goods with an adhesive label with a plurality of formations. The invention further relates to a container comprising the resealable container. The container is particularly employed as a container for elongated shaped smoking products such as cigarettes.
    [0002] Smoking products, such as cigarettes and cigars, are commonly packaged in rigid, hinged lid containers having a box and lid connected to the box portion around a hinged line extending through the rear wall of the container . Such hinge-lid containers are typically constructed from a single laminar cardboard blank. In use, the lid portion is pivoted about the hinge line to open the container and gain access to a bundle of smoking articles contained in the box portion.
    [0003] The bundle of smoking articles in the box portion is typically wrapped in an inner layer of metallized paper, laminated paper or other flexible sheet material. To access the bundle of smoking products within the inner layer, a consumer typically removes and discards a pre-pierced top portion of the inner wrapper by first opening the hinge-lid container.
    [0004] However, for greater protection against ingress and egress, for example, of air, moisture, flavors and odors, it is also known to enclose smoking products in a resealable, substantially air-tight enclosure.
    [0005] For example, EP-A-0 944 539 presents a hinge-lid package of smoking articles, in which the smoking articles are accommodated in a sealed box of a layer of barrier material having an opening defined there. The access opening is covered by a coating layer with a permanently adhesive surface that can be engaged with the layer of barrier material to seal the housing after first opening the opening portion. To help open and close the sealed enclosure, a non-adhesive flap is provided at the lower end of the cover layer.
    [0006] WO-A-2008/142540 also presents a pack, with hinged lid, in which smoking articles are arranged in an inner pack with an extraction opening closed by a lid flap which is fixed to the inner pack using a non-dry re-adhesion adhesive applied to the underside of the lid flap. The inner or outer surface of a lower flap of the lid layer is permanently and non-removably glued to an inner surface of the lid of the hinged lid package so that the opening and closing operation of the lid simultaneously also opens and closes the lid flap.
    [0007] When such a container is opened, the consumer can feel the resistance of the peeling force that needs to be overcome to separate the lid casing from the underlying surface. When the lid layer, or flap, is opened and closed several times, the consumer's tactile experience may change during opening of the lid layer, or flap, due to the irregularity of the adhesive connection. Furthermore, the force required to open the lid layer, or flap, changes depending on the number of times the lid layer, or flap, has been opened. Therefore, it would be desirable to provide a resealable container to improve the opening characteristics of consumer goods, such as a more uniform opening force, or a tactile feel to the user. It would also be desirable to provide a resealable container with a controllable opening force.
    [0008] According to one aspect of the present invention, a resealable container for consumer goods is provided. The resealable container comprises a package for containing consumer goods. The package has an access opening through which consumer goods can be removed. The resealable container also comprises an adhesive layer that covers the pack access opening and extends beyond the periphery of the pack access opening. The adhesive wrap is at least partially secured to the pack by means of a resealable adhesive provided on the inner surface of the wrap which extends around at least a sealing portion of the pack located on the periphery of the access opening. At least the sealing portion of the pack is provided with a plurality of formations provided in a continuous, repetitive pattern, and spaced in separate rows. The plurality of formations are adapted to reduce the effective area of the sealing portion.
    [0009] The term "effective area" is used throughout the specification to refer to the area of the sealing portion that predominantly contributes to the peel force when the adhesive layer is peeled off from the underlying surface of the inner package.
    [00010] The term "inner surface" is used throughout the specification to refer to a surface of an assembled container component facing the inside of the container, for example, to the consumer good when the container is in position closed. Likewise, the term "outer surface" is used throughout the specification to refer to the surface of a container component that faces the outside of the container. For example, the inner structure comprises an outer surface facing the outer container housing and an inner surface facing the inner container package. It should be noted that the inner or outer surface is not necessarily equivalent to a certain side of a blank used in the container assembly. Depending on how the stock is folded around the consumables, areas that are on the same side of the container may face either towards the inside or towards the outside of the container.
    [00011] The fact of providing a plurality of formations in the sealing part allows the removal force to be controlled. Furthermore, the fact of providing a plurality of formations in the sealing part can improve the tactile sensation for the user when opening the resealable container. The opening quality can be improved by reducing the standard deviation of the removal force in a series of opening operations. This is particularly advantageous in the form of a sealed pack, where the operation of sealing and removing the seal from the adhesive layer functions simultaneously with the opening and closing of a lid of a hinge-lid container, for example, as described in WO-A -2008/142540. It has been found that, advantageously, despite the reduction of the effective sealing area, the sealing moisture barrier property is maintained.
    [00012] The adhesive layer provided to cover the access opening comprises a resealable adhesive, i.e. the adhesive layer can be removed from the sealing part of the package and fixed again several times. This allows the opening and closing of the package to individually access the consumer good. This allows the package to be opened and closed multiple times for individual access to consumer goods. The resealable adhesive on the adhesive layer will preferably provide sufficient adhesion for the adhesive layer to be re-attached at least as long as consumer goods are available within the package. With this, a consumer will be able to open and reseal the package until the package is finished.
    [00013] Those skilled in the art already know the suitable resealable adhesives; a wide range of stickers are marketed by numerous suppliers. Selection of a suitable adhesive may depend on the material that forms the sealing portion of the package to which the adhesive layer is sealed and resealed during use.
    [00014] The adhesive layer preferably comprises an adhesive-free surface area. This area corresponds, in size, to the access opening in the package. When the lid is in the closed position, with the adhesive layer sealed to the package, this adhesive-free surface area covers the access opening to the inner package. This will prevent the adhesion, on the adhesive layer, of dust or small particles, eg tobacco particles or other residues of the consumer good contained in the package. This is likely to happen if the adhesive layer comes into contact with the consumer good on the inside of the package.
    [00015] The opening of package access can be defined by one or more detachable lines in the package. In this modality, one or more detachable lines define an access part of the package. By providing the pack with a defined access portion, the pack can be more securely sealed prior to the first opening of the resealable container. This can extend the life of the consumables contained within the resealable container. In this embodiment, the adhesive layer preferably comprises another area of the inner surface of the adhesive layer permanently attached to the access portion of the pack connected by one or more detachable lines. The access portion of the package is preferably partially separated from the remainder of the package along one or more tear-off lines at the first opening of the adhesive layer, such that the access portion of the package remains connected to the remainder of the package, so such that the access portion of the pack remains attached to the remainder of the pack during the subsequent opening and closing of the adhesive layer. The resealable adhesive provided on the first area of the inner surface of the adhesive layer may extend substantially over the entire periphery of the access portion of the pack.
    [00016] Preferably, the adhesive layer is permanently attached to the pack, at least in an area of the resealable pack. More preferably, the adhesive layer is permanently attached to the pack by a connecting portion which extends substantially over the entire periphery of the adhesive layer. The connecting portion is connected to the adhesive layer along the edge of the adhesive layer adjacent to an end of the access portion. Preferably, the connecting end is located towards the rear of the upper side of the pack.
    [00017] The plurality of separate rows of formations may be substantially linear, or may be substantially non-linear. The rows may comprise a combination of substantially linear and substantially non-linear rows. Rows can alternate between substantially linear rows and substantially non-linear rows. Alternatively, a plurality of substantially linear rows may be provided with a single substantially non-linear row, for example, from the longitudinal centerline of the pack. Any other suitable combination of substantially linear and non-linear rows is considered.
    [00018] Substantially non-linear rows may be wavy rows, or zigzag-shaped. The substantially non-linear wavy rows can be substantially regular-function waves such as a sine wave. Substantially non-linear zigzag rows may have substantially regular zigzag wave functions, such as a triangle wave function or a sawtooth wave function.
    [00019] Substantially non-linear rows can be wavy rows, or zigzag rows. The substantially non-linear wavy rows can have substantially regular wave functions, such as a sine wave. The substantially non-linear zigzag rows may have substantially regular zigzag wave functions, such as a triangle wavefunction or a sawtooth wavefunction.
    [00020] The plurality of training is provided in a pattern of continuous repetition. The forming plurality can thus be manufactured more easily using embossing or non-embossing embossing machines or printing machines. The continuous repetitive pattern can provide the user with a tactile sensation when opening the resealable container. The plurality of formations is preferably evenly spaced along the sealing portion. As used herein, "regularly spaced" means that the distances between each formation and its adjacent formations are substantially equal. A continuous repeat pattern can advantageously simplify production and ensure a uniform seal quality across a series of resealable packages subsequently produced, eliminating the requirement for accurate pattern registration with opening limits in the resealable package.
    [00021] By controlling the pattern of formations, the user's tactile experience can also be controlled. Furthermore, the sealing of the adhesive layer in the pack can be controlled, for example, by providing a smaller amount of seals substantially adjacent to the access opening to increase, in place, the surface area of the sealing portion and thus improve the seal. right next to the access opening.
    [00022] The row of formations can be parallel to the direction in which the adhesive layer is removed from the package. Alternatively, the rows can be perpendicular to the direction in which the adhesive layer is removed from the package. In another embodiment, a combination of rows parallel to the direction in which the adhesive layer is removed and rows perpendicular to the direction in which the adhesive layer is removed may be provided.
    [00023] The adhesive layer is removed from the package along the longitudinal direction and thus, where the rows of formations are parallel to the removal direction, they are parallel to the longitudinal axis of the package. Where rows are perpendicular to the removal direction, they are parallel to the transverse axis of the package.
    [00024] By providing the forming rows parallel to the removal direction, the force required to remove the layer from the pack can be substantially constant during a removal operation. However, where the forming rows are provided perpendicular to the removal direction, the force required to remove the layer from the pack may alternate between a low and high removal force during a removal operation. The force can be controlled by establishing, for example, the spacing between the formation rows. In this way, the user can feel a zipper-like effect, so that he has a better tactile experience. Furthermore, providing rows of formations perpendicular to the removal direction can provide a sound to be generated when the adhesive layer is removed from the package. Sound is generated by varying the peel force, causing the adhesive layer to vibrate. By controlling the distance between each row of formations and the width of each row, the sound generated can be varied when the adhesive layer is removed from the package. For example, a short sound such as a jingle may be generated whenever the adhesive layer is removed from the package.
    [00025] A plurality of formations can be provided on substantially the entire front wall of the pack. Providing the plurality of formations on substantially the entire front wall of the pack allows the pack to be manufactured more easily since the formations can be made in a continuous process. Likewise, the plurality of formations can be provided on all the walls of the pack and thus the pack can be manufactured more easily.
    [00026] The formations can reduce the effective area of the sealing part by at least 10%, preferably about 15%, more preferably at least 17%. In some embodiments, formations can reduce the effective area of the sealing portion by up to 25%. The formations reduce the effective area of the sealing portion, preventing sections of the sealing portion from contacting the adhesive layer. This can be achieved, for example, by means of embossed structures or structures that do not have embossed embossing on the surface of the package.
    [00027] The term "not embossed" is used to refer to a structure that is formed towards the inside of the package. The term "embossed structure" is used to refer to a structure that is formed towards the outside of the package. In a non-embossed structure, the effective surface area is reduced, as the non-embossed structure does not contribute to the peel strength as the adhesive layer only enters the non-embossed structure. embossed as follows: either partially, or not at all. In an embodiment with non-embossed structures, the adhesive layer is predominantly on the non-embossed surface such that the sealing and moisture retention properties of the seal are maintained. In an embodiment with an embossed structure, the effective surface area is substantially reduced to the peaks of the structure. In this modality, the unembossed "valleys" between the embossed structures do not contribute significantly to the removal force, if at all. In some embodiments, a combination of embossed structures and non-embossed structures may be desired. In some embodiments, the entire surface of the package may be embossed or not embossed.
    [00028] By preventing the adhesive layer from contacting the sealing part of the package in a controlled manner, the force required to remove the adhesive layer from the package can be reduced, but the seal formed between the adhesive layer and the package is not adversely affected . Reducing the force required to remove the adhesive layer from the pack allows the standard deviation of the peel force during a peel operation to be reduced. The effect of a reduction in the standard deviation of the peel force is that the operation of removing the adhesive layer from the pack is more uniform.
    [00029] Alternatively, the reduction in peel strength can be achieved by reducing the strength of the adhesive used in the adhesive layer. However, it has been found that the adhesive strength decreases with each peeling operation and thus if the adhesive strength of the adhesive layer is initially reduced, the adhesive layer may not adhere properly after a series of peeling operations. Thus, reducing the effective area of the sealing portion of the pack advantageously allows the adhesive force to remain suitably high, while reducing the force required to remove the adhesive layer from the pack.
    [00030] Each formation can have a circular, triangular, rectangular or any other suitable polygonal shape. The shape of the formation, as used herein, is the shape of the two-dimensional projection onto the surface of the package. The formation may have a three-dimensional shape, such as hemispherical, cone, pyramid, trunk, cuboid, trapezoidal prism, or any other suitable three-dimensional shape.
    [00031] The formations can be formed by making embossed or unembossed stamping on the package material. Embossing, or embossing, is preferably done before the pack is assembled and as such substantially the entire pack can be provided with a plurality of formations. Alternatively, formations can be printed on the package. Where formations are printed, the formations can be formed using varnish.
    [00032] The package may comprise an internal structure, provided within the package, adapted to increase the structural resilience of the package, such that the adhesive layer can be more easily sealed to the package.
    [00033] Preferably, the inner frame is a U-shaped inner frame having a front wall and a pair of opposite side walls. The term "U-shaped" is used to refer to a shape comprising three parts, in which the first and third parts are parallel to each other and extend in the same direction perpendicular to the second part.
    [00034] Preferably, the front wall of the inner frame is provided adjacent to the front wall of the pack. Advantageously, an internal structure with a large surface area provided adjacent to the front wall of the pack increases the structural strength of the pack. The structural strength increased by the internal structure allows for a more secure closure of the adhesive layer. This is particularly advantageous for subsequent close operations when the package is no longer full.
    [00035] Preferably, the inner frame comprises a cut in the upper part of the front wall. The cut preferably corresponds to the access opening and is provided in such a way that the consumer goods inside the package can be more easily accessed. Where the inner frame comprises a cut, the height of the inner frame is defined as the distance from the bottom of the inner frame to the cut.
    [00036] As used herein, the terms "front", "rear", "bottom", "top" and "side" refer to the relative positions of the parts of the containers according to the invention and its components when the container is in a straight position, with the outer housing cover in the closed position and the pivot line, where present at the rear of the container. When describing containers in accordance with the present invention, these terms are used irrespective of the orientation of the container being described. The rear wall of the container is the wall comprising the hinge line.
    [00037] In a preferred embodiment, a container for consumer goods is provided, which comprises a box adapted to receive a resealable package, as described herein. The container also comprises a lid hinged to the box along a hinge line extending through a rear wall of the container.
    [00038] In this preferred embodiment, the adhesive layer may be permanently affixed to the inner surface of the front wall of the cover such that upon opening the cover, the adhesive layer is removed to reveal the access opening. As such, when the user opens the container lid, the adhesive layer is automatically opened to reveal the access opening, and when the user closes the lid, the adhesive layer is automatically closed to seal the access opening.
    [00039] The term "longitudinal" refers to a direction from the bottom to the top, or vice versa. The term "transverse" refers to a direction perpendicular to the longitudinal direction.
    [00040] As used herein, the term "height" refers to the dimension of the respective part of the adhesive layer measured in the longitudinal direction when the adhesive layer is attached to the inner package. The term "width" refers to the dimension of the respective part of the adhesive layer measured in the direction when the adhesive layer is attached to the inner package.
    [00041] The container is preferably a rectangular parallelepiped comprising two broad walls, spaced apart by two narrower walls.
    [00042] The term "hinging line" refers to a line around which the lid can be hinged to open the container. A hinged line can be, for example, a creased line, a wrinkled line or a dashed line on the panel forming the rear wall of the container.
    [00043] The container may be formed from any material, including but not limited to cardboard, plastic, metal or combinations thereof. Preferably, each outer housing is formed from one or more laminar, folded cardboard blanks, and preferably, the cardboard has a weight between 100 grams per square meter and about 350 grams per square meter.
    [00044] Preferably, the inner package is formed of metallized paper or aluminum foil. The inner packaging material can be formed as a laminate of metallized polyethylene film and a liner material. The inner material can be GLASSINE supercalendered paper. In addition, the inner packaging material may be provided with a print-receptive top coating.
    [00045] As described above, the containers according to the invention can be in the form of a rectangular parallelepiped, with transverse ends at right angles or longitudinal ends at right angles. Alternatively, the container may comprise one or more rounded longitudinal ends, rounded transverse ends, beveled longitudinal ends or beveled transverse ends, or combinations thereof. For example, the container according to the invention may comprise, without limitation: one or two rounded or bevelled longitudinal ends in the front wall, and/or one or two rounded or beveled ends in the rear wall.
    [00046] One or two transverse rounded or chamfered ends in the front wall and/or one or two transverse rounded or chamfered ends in the rear wall.
    [00047] A longitudinal rounded end and a longitudinal chamfered end on the front wall and/or a longitudinal rounded end and a transverse chamfered end on the rear wall.
    [00048] Two rounded longitudinal ends or chamfered ends in a first side wall or two rounded ends or transversely chamfered ends in the second side wall.
    [00049] Where the container comprises one or more chamfered end, preferably the chamfered end has a width between about 1 mm and about 10 mm, preferably between about 2 to about 6 mm. Alternatively, the container may comprise a double bevel formed by three parallel corrugated or dashed lines which are spaced apart such that two distinct bevels are formed at the end of the container.
    [00050] Alternatively, the container may have a non-rectangular cross section, for example polygonal such as a triangular or hexagonal, semioval or semicircular section.
    [00051] The containers according to the invention particularly apply to packages for elongated smoking articles, such as, for example, cigarettes, cigars or cigarillos. It will be appreciated that, through appropriate choices of their dimensions, the containers according to the invention can be designed for different conventional cigarette sizes, such as king size, super king size, thin or super thin. Alternatively other consumer goods can be packed in the container.
    [00052] Through an appropriate choice of their dimensions, containers according to the invention can be designed to contain different amounts of smoking articles, or different arrangements of smoking articles. For example, by appropriately choosing their dimensions, containers according to the invention can be designed to hold a total of between ten and thirty smoking articles.
    [00053] Smoking articles can be accommodated in different rows depending on the total number of smoking articles. For example, smoking articles can be arranged in a single row of six, seven, eight, nine or ten. Alternatively, the smoking articles can be arranged in two or more rows. The two or more rows can contain the same amount of smoking articles. For example, smoking articles can be arranged in: two rows of five, six, seven, eight, nine or ten; three rows of five or seven or four rows of four, five or six. Alternatively, the two or more rows may include at least two rows containing different amounts of smoking articles; For example, smoking articles can be arranged in: one row of five and one row of six (5-6); a middle row of six and two outer rows of five (5-6-5); a middle row of six and two outer rows of seven (7-6-7); a middle row of seven and two outer rows of six (6-7-6); a middle row of nine and two outer rows of eight (8-9-8); or a middle row of six with an outer row of five and an outer row of seven (5-6-7).
    [00054] Containers according to the present invention may contain smoking articles of the same type or brand, or of different types and brands. Furthermore, both unfiltered smoking articles and smoking articles with multiple filter ends may be contained in the container, as well as smoking articles of different length (e.g., between about 40 mm and about 180 mm), diameter (for example, between about 4 mm and about 9 mm). In addition, smoking articles may differ in terms of taste (strong or weak), drag resistance and overall particulate matter distribution. Preferably, the dimensions of the container are adapted to the length of the smoking articles and the arrangement in rows of the smoking articles. Typically, the external dimensions of the container are between 0.5 mm and about 5 mm larger than the dimensions of the set of smoking articles accommodated within the container.
    [00055] The length, width and depth of the containers, according to the invention, may be such that, in the closed lid position, the resulting total dimensions of the container are similar to the dimensions of a typical disposable package, with hinged lid, of 20 cigarettes.
    [00056] Preferably, containers according to the invention have a height of between 60 mm and about 150 mm, more preferably a height between about 70 mm and about 125 mm, wherein the height is measured from the wall bottom to the top wall of the container.
    [00057] Preferably, containers according to the invention have a width of between about 12 mm and about 150 mm, more preferably a width of between about 70 mm and about 125 mm, wherein the width is measured from one sidewall to the other sidewall of the container.
    [00058] Preferably, containers according to the invention have a width of between about 12 mm and about 150 mm, more preferably a width between about 70 mm and about 125 mm, wherein the width is measured by a side wall to the other side wall of the container.
    [00059] Preferably, containers according to the invention have a depth between about 6 mm and about 150 mm, more preferably a depth between about 12 mm and about 25 mm, wherein the depth is measured from the front wall to the rear wall of the container (comprising the articulation between the box and the lid).
    [00060] Preferably, the ratio of container height to container depth is between about 0.3 to about 10 to 1, more preferably between about 2 to 1 and about 8 to 1, more preferably between about 3 to 1 and 5 to 1.
    [00061] Preferably, the ratio of container width to container depth is between about 0.3 to 1 and about 10 to 1, more preferably between about 2 to 1 and about 8 to 1, most preferably between about 2 to 1 and 3 to 1.
    [00062] Preferably, the ratio of the height of the lid rear wall to the height of the outer glove box rear wall is between about 0 to 1 (the lid being located at the upper end of the container) to about 1 to 1, more preferably between about 1 to 5 and about 1 to 10, more preferably between about 1 to 6 and about 1 to 8.
    [00063] Preferably, the ratio of the height of the front wall of the outer glove cover to the height of the front wall of the outer glove box is between about 1 to 0 (the cover covering the entire front wall) to about 1 to 10 more preferably between about 1 to 1 and about 1 to 5, more preferably between about 1 to 2 and about 1 to 3.
    [00064] Where the container comprises smoking articles, the container may further comprise compartments for waste (e.g., ash or butts) or other consumer goods, e.g., matches, lighters, extinguishing devices, products to cool the mouth or electronic products. The other consumer goods may be attached to the outside of the container, contained within the container together with the smoking articles, in a separate compartment of the container, or a combination thereof.
    [00065] The external surfaces of the containers, according to the invention, may be printed, embossed, without embossing or otherwise embellished with the manufacturer's logo, brands, slogans and other information and notices for the consumer .
    [00066] The containers according to the invention, with the smoking articles already accommodated, can be hermetic packaging or otherwise have an overlay packaging of transparent film of, for example, polyethylene, polypropylene, oriented polypropylene, chloride polyvinylidene, cellulose film, low or high intensity, or combinations thereof, in a conventional manner. Where containers according to the invention have an overlapping package, the overlapping package may include one or more tear strips. In addition, the overlay package can be printed with images, information or other consumer data.
    [00067] Any feature in one aspect of the invention may be applied to other aspects of the invention, in any suitable combination. In particular, the method aspects can be applied to the apparatus aspects and vice versa. In addition, any, some and/or all of the other features in one aspect may apply to any, some and/or all of the features in any other aspect, in any appropriate combination.
    [00068] The invention will be further described, by way of example only, with reference to the attached drawings, in which:
    [00069] Figure 1 shows a perspective view of a container, according to the present invention, with the lid in an open position;
    [00070] Figure 2 shows an example of a tactile pattern provided on the container; and
    [00071] Figures 3 (a) and (b) show examples of a tactile pattern in the transverse direction of removal and in the same direction of removal, respectively.
    [00072] Figure 1 shows a perspective view of the container 100 comprising a resealable package with the lid in an open position. Container 100 comprises a box 102 and a lid 104 hinged to the box along a hinge line on the box rear wall. The box has a resealable package 106 on the inside. The resealable package 106 is provided with an adhesive layer 108 to seal the resealable package when the container is not in use. The adhesive layer 108 is permanently attached to the inner surface of the front wall 110 of the lid portion 104. By permanently attaching the adhesive layer to the lid portion, the adhesive layer is automatically removed from the resealable package when the lid is moved from position closed to the open position shown in figure 1.
    [00073] To allow the adhesive layer to be firmer and more easily sealed in the resealable package, an inner structure 112 is provided within the resealable package 106. The inner structure is a cardboard element, having a front wall and two opposite side walls . The side walls of the inner frame 112 act to reinforce the front wall of the resealable pack. Thus, the resealable pack is better able to withstand the forces applied to the front wall of the resealable pack when the adhesive layer is resealed on the pack. An access opening 114 is provided in the top wall and front wall of the resealable pack. As can be seen, a plurality of formations 116 are provided on the front wall of the resealable pack in the area which the adhesive layer seals with the pack when in the closed position. This area is a sealing part of the resealable package and the formations act to reduce the effective area of the sealing part. This is discussed in more detail below.
    [00074] In use, when the cover is moved from the closed position to the open position, the adhesive layer is automatically removed from the package to reveal the access opening. As can be seen, the adhesive layer is removed in the direction corresponding to the longitudinal axis of the container.
    [00075] Figure 2 shows an example of the material 200 used for the sealing part 116 of the resealable package 106. In that example, formations 202 are provided in the material. The formations are embossed or unembossed into the material by means of an embossing machine before the material is formed into the resealable package. The formations 202 are pyramid-shaped, but can be any three-dimensional shape. In a preferred embodiment, the formations reduce the effective surface area of the sealing portion by about 17%. As can be seen, formations 202 are provided in spaced rows. Row orientation is described in detail below.
    [00076] Embossed or non-embossed formations act to reduce the effective area of the sealing portion of the package by preventing the adhesive layer from contacting the material portion within the formation. This has the effect of reducing the force required to remove the adhesive layer from the sealing part. This allows the resealable adhesive used to seal the adhesive layer to the pack to have a conventional strength, but reduces the variation in the average force required to remove the adhesive layer during the peeling operation. Therefore, the user improves the tactile sensation. Using a resealable adhesive, with conventional strength, ensures that the adhesive layer remains properly adhered to seal the adhesive layer even after several opening operations.
    [00077] Figures 3(a) and 3(b) show examples of a tactile pattern in the transverse direction of removal and in the same direction of removal, respectively. The material 300 shown in Figure 3(a) is provided with a plurality of formations in spaced rows, as described above with respect to Figure 2. As indicated by arrow 302, the direction of removal is substantially parallel to the direction of the formation rows. As the rows of formations are parallel to the direction of removal, the force required to remove the adhesive layer from the sealing portion of the resealable pack remains substantially constant during an opening operation. The result of having formation rows in the removal direction is to provide the user with a pleasant tactile sensation.
    [00078] In an alternative, as shown in Figure 3(b), the material 304 for the sealing portion of the pack is provided with a plurality of formations in spaced rows that are substantially perpendicular to the direction of removal 306. formations in spaced rows perpendicular to the removal direction can create an effect called a zipper effect. The zipper effect is experienced by the user as a high to low oscillating force when the adhesive layer is removed from the package. The initial strength is high due to the fact that the surface area in the region adjacent to the line of removal of the adhesive layer is continuous and uninterrupted by formations in the material. The peel line is the imaginary line between the adhesive layer and the resealable package; extends across the width of the adhesive layer. When the peel line intersects the row of formations, the peel force is reduced due to the fact that the decrease in surface area of the adhesive layer is in contact with the resealable package. As the peel line passes over the row of formations, the surface area of the adhesive layer being in contact with the resealable pack increases due to the absence of formations. This process is repeated whenever a row of formations is encountered and thus an oscillating removal force is generated. By changing the spacing between rows and the width of each row, the frequency and amplitude of the oscillating pullout force can be adjusted to provide the user with a better tactile feel and a potentially acoustic feel.
