    CUP WITH INTEGRAL CLOSING FLASHES THAT LIMIT SPILL The present invention relates to a container (1) comprising a wall (2) that has a closed base (4) at one end and a generally circular or oval rim (5) at one opposite end, the rim defining an upper opening (6) of the container. The container (1) further comprises a flap arrangement (70, 80) so that the neutralizing forces between a rim of a first flap (70) and the inner face of a second flap (80) are sufficient to push the respective flap and the inner face together for airtight contact. A closure arrangement (300a, 300b) is provided to limit flap openings (100a, 100b) formed at or below the rim (5) of the container between the flaps (70, 80) to prevent splashing and reduce the spill rate if the container is dropped. The present invention thereby improves the spill-resistant properties for the container (1) while, if required to drink or spill, it allows the container to allow a liquid to pass in when bent to drink and spill.

    [001] The present invention relates to containers for cold and hot drinks or food and in particular disposable containers made of resilient-flexible material, such as cardboard or plastic.
    [002] Known disposable containers, such as those used in fast food stores or vending machines, normally comprise a body in the form of an inverted truncated cone having a closed base and an open top. To avoid spilling the contents of the container, a lid is usually placed over the opening of the container. Such lids are typically molded of a plastics material. A supply of matched lids needs to be kept available to a user close to the supply of containers at the point of sale. Obviously, a lid must be compatible with the opening of the container in order to fit securely over the rim of the container and prevent spillage. There are several disadvantages associated with the use of such lids. Although having the same general configuration as a truncated cone, disposable containers come in different sizes and therefore, for each container size, a different lid is usually required. Maintaining an inventory of matching lids for every container size involves additional expense, requires additional storage space and managerial resources. In addition, it is often difficult to even place a matching lid over the opening of the container in a single attempt and typically some manipulation is required before the lid is finally properly placed in place. In addition, if the lid is pressed a little harder against the rim of the container, the container may tip over and cause the contents to inevitably escape from the container. Since most disposable lids have a spout / opening, there is still a relatively high risk of spillage through the spout, for example, when a person carrying the container walks or manipulates other objects, such as keys, cell phone, etc. Due to the relentless popularity of fast food services, huge amounts of disposable containers and lids are being used and disposed of around the world on a daily basis. Although many disposable containers are made of cardboard, which are renewable and recyclable, the lids are generally made of plastic that are much less environmentally friendly.
    [003] A known type of known container that seeks to provide a provision for closing a disposable container in the form of a cup is disclosed in WO2011 / 063835. This known tapered cup is made of a resilient flexible material, having a circular rim that defines the top opening of the cup. A pair of arched crease lines are formed on opposite sides of the cup wall below the rim defining a pair of flaps to close the upper body opening by folding the flaps along the crease lines. Due to the resilience of the cup material, each flap can alternate between two stable positions in the application of an initial external force on the flap, namely an open vertical position in which the flap is convex and forms part of the cup wall, and a closed inclined position in which the flap changes its shape to concave. In closed mode, the rim of a flap falls against the inner face of the second flap and forms a seal between the flaps. The seal is maintained due to opposing static forces acting between the flaps. Another cup with closure flaps is revealed in GB 2380397.
    [004] However, a problem associated with this known cup is that when the rim of a flap falls against the inner face of the second flap, there are gaps or flap openings between the flaps adjacent to the ends of the crease lines, and these gaps provide openings in the seal through which the contents of the coop may splash or spill.
    [005] In view of the above, it is an objective of the present invention to alleviate and reduce the above disadvantages and to provide an improved arrangement for a disposable recipient to reduce or limit splashing and spilling of the container contents.
    [006] Accordingly, the present invention provides a container comprising a wall having a closed base at one end, a generally circular or oval rim at an opposite end, the rim defining an upper opening of the container, the container comprising still:
    [007] A pair of substantially arched crease lines formed on the container wall on opposite sides of the wall below the rim; wherein each crease line has first and second ends coinciding with the rim; wherein each crease line and the portion of the rim between the first and second ends of the crease line define a flap having an outer face and an inner face; where each crease line is configured to act as a joint that allows each flap to alternate between two stable positions after applying an initial external force on the flap, the two stable positions being an open vertical position, in which the flap is convex and it forms part of the container wall, and a closed inclined position in which the flap changes its shape to concave; wherein the resilience of the flap material causes the flap to complete the toggle and prevents the flap from stopping in an intermediate position to the open vertical and closed inclined positions; and
    [008] The length of each crease line and the shortest distance between a point on the crease line axially more remote from the rim of the flap and the rim are selected in such a way that when the flaps are closed, each flap takes on a inclined orientation in relation to the base of the container, so that the rim of a first flap falls against the inner face of the second flap so that the second flap remains statically forced against the rim of the first flap due to the resilience of the container material of that thus forming a seal between the rim of the first flap and the inner face of the second flap, whereby the two flaps form a double sloping roof through the upper opening of the container, characterized by the fact that the container further comprises an arrangement of operable closure to limit at least one flap opening defined in or adjacent to a position where the ends of the crease line coincide with the rim of the container when the flaps are folded, in which the arrangement d and closure comprises at least one wing extending from the container wall and below the flap opening when the flaps are in the closed inclined position.
    [009] Due to the above-described arrangement of the container of the present invention, when one of the flaps, for example, the first flap, is allowed to move fully to the closed inclined position, while the second flap is prevented from moving completely to the closed inclined position by the rim of the first flap, so that the rim of the first flap is prevented from being deformed by the second flap due to the resilience of the container material, so that the second flap remains statistically strengthened against the rim of the first flap towards the position closed slope due to the resilience of the container material. The neutralizing forces between the rim of the first flap and the inner face of the second flap are sufficient to push the respective rim and the inner face together in a hermetic contact, however it forms a seal having gaps in or adjacent where the ends of the lines of crease coincides on the rim of the container, and these gaps or flap openings are problematic, as they can cause the contents of the container to spill.
    [010] The provision of a closure arrangement, according to the characterization portion of the invention, is operable to limit the flap openings formed in the rim of the container when the flaps are switched to the closed inclined position, and thus provide a means to prevent or improve against splashing the contents of the container and reduce the spill rate if the container is dropped. The present invention thereby improves the spill-resistant properties for the container while, if required to drink or spill, allowing the container to allow liquid to pass in when bent over to drink and spill.
    [011] Preferably, each wing is operable to pivot around the container wall to limit the opening of the flap. Preferably, each wing extends from an inner face of the container wall.

    [019] Preferably, the closure arrangement comprises a pair of wings, each wing extending from the wall of the container under a flap opening when the flaps are in the closed inclined position.
    [020] In another embodiment of the invention, a container is provided comprising a wall having a closed base and a generally circular or oval rim at an opposite end, the rim defining an upper opening of the container, the container further comprising :
    [021] A pair of substantially arched crease lines formed on the container wall on opposite sides of the wall below the rim; wherein each crease line has first and second ends coinciding with the rim; wherein each crease line and the portion of the rim between the first and second ends of the crease line define a flap having an outer face and an inner face; where each crease line is configured to act as a joint that allows each flap to alternate between two stable positions after applying an initial external force on the flap, the two stable positions being an open vertical position, in which the flap is convex and it forms part of the container wall, and a closed inclined position in which the flap changes its shape to concave; wherein the resilience of the flap material causes the flap to complete the toggle and prevents the flap from stopping in an intermediate position to the open vertical and closed inclined positions; and
    [022] The length of each crease line and the shortest distance between an axially most remote crease point from the flap rim and the rim are selected in such a way that when the flaps are closed, each flap takes on a inclined orientation in relation to the base of the container, so that the rim of a first flap falls against the inner face of the second flap so that the second flap remains statically forced against the rim of the first flap due to the resilience of the container material of that thereby forming a seal between the rim of the first flap and the inner face of the second flap, whereby the two flaps form a double sloping roof through the upper opening of the container; characterized by the fact that the container further comprises an operable closure arrangement to limit at least one flap opening defined at or adjacent to a position where the ends of the crease line coincide with the rim of the container when the flaps are folded, wherein the closing arrangement comprises at least one tongue to limit to a flap opening, where each tongue is located in a region of the container where the ends of the crease lines coincide with the rim of the container, and when the flaps are pivoted to the closed inclined position each pivot tongue around a fold line so that portions of the tongue on each side of the fold line that project above the rim of the container are folded together and limit the opening flap.

    [047] In the following description the characteristics of the present invention will be described as they refer to a container incorporated as a cup. However, it will be understood that other modalities for a container are also considered, such as a jug, a box, and a container for drinking or for carrying or storing a liquid, semi-solid or solid content, and that, therefore, reference in the The following description to a container formed as a cup only should not be in any way limiting.
    [048] With reference initially to figures 1 to 7, a glass according to the prior art is generally indicated by reference numeral 1. Glass 1 is made of a flexible resilient material, such as cardboard or plastic.
    [049] The cup 1 has a wall 2 in the form of a truncated cone having a central axis 3, a closed base 4 of an optionally smaller diameter at one end and a generally circular rim 5 of an optionally larger diameter at an opposite end. It will be recognized that the invention is not limited to a circular cross section of the cup wall. Indeed, a generally oval cross-section of the cup is included in the scope of the present invention. It is also within the scope of the present invention to have a protruding spout or opening for drinking. The rim 5 defines an upper opening 6 of the body 1. The rim 5 and the base 4 can also be of the same diameter.
    [050] A pair of substantially arched crease lines 7, 8 is formed on the wall 2 of the cup 1 on opposite sides of the wall 2 below the rim 5. Each crease line 7, 8 has first and second ends 7a, 8a and 7b , 8b respectively. The ends of the crease lines 7a, 8a, 7b, 8b coincide with the rim 5. Also, each end 7a, 7b of a first crease line 7 substantially coincides with a corresponding end 8a, 8b of the second crease line 8 in the rim. 5 of the cup, although it is understood that to provide a container having a spout for pouring or drinking or funnel the ends 7a, 7b, 8a, 8b of the crease lines 7, 8 cannot coincide with each other in the rim 5 in order to create a sufficiently wide opening in the rim 5, as shown in figure 7 by gaps 5a, 5b, thereby creating an opening or pouring or funnel 100a, 100b.
    [051] Each crease line 7, 8 and the respective portion 57, 58 of the rim 5 between the respective first and second ends 7a, 7b; 8a, 8b of the crease line 7, 8 define a flap 70, 80, respectively. Each flap 70, 80 has an outer face 70a, 80a and an inner face 70b, 80b, respectively.
    [052] Each crease line 7, 8 is configured using a suitable method (for example, by flexing, marking or differential forming, as in the case of plastic cups, the material of wall 2) to act as a joint to allow each flap 70, 80 alternates between two stable positions after applying an initial external force on flap 70, 80. One of the two stable positions is an open vertical position in which flap 70, 80 is convex and forms part of the cup wall 2 , for example, as shown in figure 1. The second of the two stable positions is a closed inclined position in which the flap 70, 80 changes its shape to concave, for example, as shown in figures 4 and 5. A flap 70, 80 is prevented from remaining in an intermediate position to the vertical open and closed inclined positions due to the resilience of its material and because in an intermediate position the flap 70, 80 becomes distorted, for example, corrugated, because the length of the flap 70, 80 in circumference directions is is greater than the length of a plane defined by the respective crease line 7, 8. When pushed to an intermediate position by an external force and after subsequent removal of the external force, the flap 70, 80 takes the concave shape in the inclined position closed or the convex shape in the open vertical position under the influence of the inherent resilience of the cup material. The resilience of the cup material makes the flap 70, 80 complete the alternation without the need for continuous application of external force and prevents the flap 70, 80 from stopping in an intermediate position to the vertical open and closed inclined positions.
    [053] The length of each crease line 7, 8 and the distance between the points P1 and P2, as shown in figure 1, respectively, of the crease line 7, 8 axi ally more remote from the rim 57, 58 of the flap 70, 80 and the rim 5 are such that when the flaps 70, 80 are closed, each flap 70, 80 assumes an inclined, curved and / or angular orientation with respect to the base 4 of the cup 1.
    [054] In addition, a first flap, for example, flap 70, is allowed to move fully to the closed slanted position as shown in figure 4. The second flap, i.e. flap 80, is prevented from moving completely to the slanted position closed by the rim 57 of the first flap which falls against the inner face 80b of the second flap 80 substantially along the total length of the rim 57 of the first flap 70. The rim 57 of the first flap 70 is prevented from being deformed by the second flap 80 due to the resilience of the material of the first flap 70 (i.e., the material of the cup 1), while the second flap 80 remains statically forced against the rim 57 of the first flap 70 towards the fully closed inclined position due to the resilience of the material of the second flap 80 (that is, the material of cup 1), as shown in figure 5. Due to continuous forced contact between the rim 57 of the first flap 70 and the inner face 80b of the second flap 80, a leak-tight seal is formed along the length of the air o 57 of the first flap 70. As shown in figures 5 to 7, the two flaps 70, 80 form a double sloping roof through the upper opening 6 of the cup 1.
    [055] However, a problem associated with this known cup 1 is that when the rim 57 of the flap 70 falls against the inner face 80b of the second flap 80 that there are noticeable gaps or flap openings 100a, 100b located close to the ex-tremes 57a , 57b, 58a, 58b of the rim 57, 58 where the ends of the crease lines 7a, 8a and 7b, 8b coincide with the rim of the cup 5a, 5b and these openings provide an outlet in the seal causing the contents of the cup to spill 1. Accordingly, the present invention now provides a closure arrangement to limit flap openings 100a, 100b to thereby prevent or ameliorate splashing of the contents of the container and reduce the spillage rate if the container is spilled. The present invention thereby improves the spill-resistant properties for the container, while, if required to drink or spill, allowing the container to allow liquid to pass in when inclined to drink and spill. It will be understood that the ends of the crease lines 7a, 8a and 7b, 8b may not coincide with the rim 50 to create an opening wide enough in the rim 5 to form a funnel or spout for drinking and / or pouring.
    [056] Referring now to figures 8 to 10, in an invention configuration, the closing arrangement comprises at least one tongue 200a and / or 200b each to limit one of the flaps or gaps 100a, 100b formed in the seal when the flaps 70, 80 are folded. Although two tabs 200a, 200b are shown in the drawings as limiting the two tab openings 100a, 100b, it will be understood that the cup container may require only a single tab where a single tab opening is to be sealed. For example, and depending on the specific application of the invention, it may be desirable to allow the contents of the container to have an unimpeded flow through one of the two flap openings, and to limit flow through the outflow of the two flap openings, in which case the inclusion of a tongue to limit the flap openings would be required. Reference to the use of a pair of tongues should in no way be seen as limiting.
    [057] Each tongue 200a, 200b is located in the cup where the ends 7a, 7b, 8a, 8b of the crease lines 7, 8 coincide with the rim 5a, 6b of the cup 1. As shown, each tongue 200a, 200b projects the from the rim 5a, 5b of the cup 1 when the flaps 70, 80 are in the open vertical position. The tongues are attached to the cup by adhesion using heat, ultrasonic welds or other suitable connection methods. The tongues can also be integrally formed when the glass is made.
    [058] The articulation of the flaps 70, 80 towards the closed inclined position causes the formation of fold lines 210a, 210b in the tongues 200a, 200b. As the tabs 70, 80 are switched to the curved and / or angled position, each closed tongue 200a, 200b pivots around its respective fold line 210a, 210b so that portions 220, 221, 222 .223 of the tongue 220a, 220b on each side of the fold line 210a, 210b that project above the rim 5 of the cup 1 are folded together causing the openings 100a, 100b to be limited by the tongues. Thus in the arrangement shown, portion 220 seals against portion 221 and portion 222 seals against portion 223. In some arrangements, when tongue portions 220, 221 are sealed together it is operable to make ends 57a and 58a of the rim 57, 58 close together and limit or in some cases completely seal the flap opening 100a. Similarly, when the tongue portions 222, 223 are sealed together it can cause the ends 57b and 58b to close together and limit or in some cases seal the flap opening 100b.
    [059] Each tongue 200a and 200b also comprises an inner face and an outer face, wherein an adhesive is provided on the inner face to further increase the restrictive effect of the closure arrangement. As shown, each tongue 220a is substantially rectangular in shape, however it will be understood that the tongues may be in any shape as required to fulfill the function described above. For example, tongues 200a, 200b can be substantially round, oval, polygonal or irregularly shaped. Accordingly, the closure arrangement comprising such tabs 200a, 200b are operable to limit or cover the openings 100a, 100b.
    [060] Referring now to Figures 11 to 16, a closure arrangement according to an additional embodiment of the invention is shown, the closure arrangement comprising a pair of wings 300a, 300b, each wing to limit one of the flap openings 100a , 100b formed on the seal when the flaps 70, 80 are folded. Although two wings 300a, 300b are shown in the drawings to limit both flap openings 100a, 100b, it will be understood that cup container 1 may, depending on the specific application of the invention, require only a single wing to be used when only one of the wings flap openings are desired to be limited. Reference to the use of a pair of wings should therefore not be seen as limiting.
    [061] As shown in figures 11 to 16, each wing 300a, 300b extends from the cup wall 2 under the flaps 70, 80 when the flaps 70, 80 are in the tilted, curved and / or angled folded or closed position. Each wing extends from an inner face of the cup wall below the opening 100a, 100b borders and is optionally fixed to the inner cup wall by a tongue 301a, 301b around which the respective wing 300a, 300b can pivot.
    [062] As shown in figure 15, the wing 300a, 300b and / or anchor tongue 301a, 301b can be folded. This feature reduces the pressure required to pull the wing down to the closed position as the wing is essentially folded back on itself and is predisposed to turn down when under pressure. The wings 300a, 300b and / or anchor tabs 301a, 301b can also be straight, rather than folded. As shown in figure 16, the wings 300a, 300b can have crease lines 320 to add resistance to the wings to make them easier to push without the outer edges deforming under pressure.
    [063] In use, the wings 300a, 300b are shaped to limit the openings 100a, 100b from inside the cup 1 to reduce splash of the contents of the container. The wings 300a, 300b can be shaped such that the edges 310a, 310b of the wings 300a, 300b engage with the inner face of the cup wall 2 to further ensure that the contents of the cup do not leak out of the openings 100a, 100b. Accordingly, a closure arrangement comprising such wings 300a, 300b is operable to limit or in some cases seal flap openings 100a, 100b to reduce splash and reduce spillage if the container is spilled. The present invention thereby improves the spill-resistant properties for the container, while, if required to drink or spill, allowing the container to allow liquid to pass in when inclined to drink and spill.
    [064] Although the wings 300a, 300b are shown to be substantially semicircular in shape, it will be understood that they can be of any suitable shape as required or desired, and can be adapted to have a shape specifically suited to the shape of the container 1 and the function that must be carried out. For example, wings 300a, 300b can be substantially round, oval, polygonal or irregularly shaped as needed. The wings are made of the same material as the container, or they can alternatively be made of heavier caliber material for added strength.
    [065] With reference to figure 17, a comb-like edge 350 can be provided along the upper edge of the wings 300a and 300b as shown in figure 16. The comb-like edge 350 helps to neutralize the energy of rising splashes from inside the container and deflect them although it does not limit the flow of liquid.
    [066] An alternative embodiment of cup 401 is shown in figure 18 and includes one or more circular paper straps 410 around the periphery of the cup. The strap or straps 410 will add strength to the structure of the cup, using an optimum amount of cardboard in relation to the desired structural strength. In a double-walled cup these straps would not be visible. A further variation of this embodiment is shown in figure 19, in which cup 501 alternatively includes crease lines, notches or ribs 510 provided in the cup wall instead of straps 410.
    [067] It will be recognized by those skilled in the art that variations and modifications can be made without departing from the scope of the invention as defined in the attached claims.
