    COLLECTION OF INDIVIDUALLY PACKED ABSORBENT ARTICLES, CONTAINER
    AND METHOD TO MAKE
    TECHNICAL FIELD
    The present invention relates to absorbent articles. More specifically, the present invention relates to an individually packaged absorbent article through a wrapping sheet.
    BACKGROUND
    Absorbent articles such as tampons, sanitary napkins, panty liners and incontinence pads are devices typically worn in the crotch region of the underwear. More specifically, sanitary napkins and panty liners, for example, are worn by women in panties that are normally positioned between the wearer's legs adjacent to the perineum area. Sanitary pads and panty liners are designed to absorb and store body fluids or stools (eg. Urine and menstruation) from the body and to prevent contamination of the body and clothing. A wide range of shapes and sizes of sanitary napkins and panty liners are currently used for a collection of body fluids.
    Recent developments for disposable absorbent articles tend not only to focus on improving product functions (eg, superabsorbent, puncture protection and comfort) but on the aesthetic characteristics. This trend also applies to sanitary napkins and baby diapers. Such disposable absorbent articles are disclosed in, for example, WO 2004/006818.
    The aesthetic designs are typically implemented by graphic printing on one (or more) component parts of these disposable absorbent articles (with a backsheet). This means that such aesthetic features have become an important product property in recent disposable absorbent articles. It is believed that such aesthetic features can offer emotional benefits to the user and thus diminish the user's melancholic mood during menstruation. So there is an intention to show aesthetic characteristics for disposable absorbent articles.
    In recent disposable absorbent articles (typically sanitary napkins and panty liners), each pillow is individually folded and enveloped by a wrapping sheet. The materials of such enclosures are typical polyethylene films or sometimes non-woven materials that are usually opaque. This is because consumers of those disposable absorbent articles do not want other people to notice or want to show that they are wearing such pillows. Even after the soiled dressing is wrapped in the wrapping sheet for removal,
    BE2017 / 0134, such an opaque packaging part can prevent the soiled dressing from being seen through the wrapping sheet. These needs conflict with the intention to display aesthetic features for disposable absorbent articles.
    Developments have been made with regard to individually packaged absorbent articles that can show an aesthetic characteristic of the absorbent article through a wrapping sheet while controlling the visibility of the soiled absorbent article observed by the wrapping sheet after use as described in EP1978905A1.
    In other alternative developments, the focus has been on providing an individually packaged absorbent article wrapped in an envelope sheet with the envelope sheet having a colored portion on the inner surface on the absorbent article side and the colored portion of the envelope sheet seen from the outside of the individually packaged absorbent article but the absorbent article cannot be seen from the outside of the individually packaged product, as described in US9278035B2.
    Nevertheless, there is always a need for individually packaged absorbents aimed at extending the user experience, not only during use, but also before and after use. In addition, there is a need for an effective means for users to identify themselves with the product and improve the sensory trip about what would otherwise remain an everyday and everyday consumer product.

    THE ABSORBING ARTICLE
    Fig. 1 is a plan view of a disposable absorbent article 122 (more specifically, a sanitary napkin) that is a preferred embodiment of the current disclosure. The absorbent article typically comprises a liquid-impermeable backsheet with a garment-facing side and a body-facing side opposite, a liquid-impervious topsheet located on the body-facing side and an absorbent core located between the backsheet and the topsheet. The absorbent core may comprise cellulose fibers and / or superabsorbent polymer particles and may further comprise a non-woven envelope enclosing said fibers and / or particles therein. A further optional interlayer may be comprised between the topsheet and the core and may be selected from any non-woven material typically used in the acquisition and distribution layer art, such as air-bonded non-woven materials. The absorbent article 122 may further comprise opposite side edges 124, 126 extending substantially parallel to a longitudinal length of the absorbent article 122 that are typically perpendicular to a width of the absorbent article. Optionally, the absorbent article 122 may include one or more wings 128, 130 on at least a portion of the side edges 124, 12.
    BE2017 / 0134
    The absorbent article 122 may further include one or more first adhesive zones 136, 138 on the garment facing back which typically extends along the length of the absorbent article 122. Such first adhesive zones may be adapted to adhere to a wrapping sheet that is arranged to form a pouch that encloses the absorbent article 122 and adheres to a garment surface of the wearer's underwear after removal of said wrapping sheet. Optionally, when the absorbent article comprises one or more wings 128, 130, each said wing 128, 130 may include a second adhesive zone 132 on the garment-facing side and controlled to adhere to a garment surface of the wearer. In this embodiment, absorbent article 122 includes at least one protective strip 134 over the second adhesive zone 132 to prevent it from adhering to the wrapper sheet forming the pouch that forms the absorbent article 122 when it is in the pre-use position (e.g. In the individually packaged state prior to use / opening).
    In an alternative embodiment (not shown), the absorbent article may be a tampon or a diaper (either for babies or adult incontinence).
    THE BUIDEL
    It should be noted that in all embodiments disclosed herein, the observing article of the publication (e.g., sanitary napkins) is packaged by a wrapping sheet, typically that the absorbent article cannot be seen by the wrapping sheet. In one embodiment, the envelope sheet has an opacity of more than 50%, preferably greater than 60%, more preferably greater than 70%, and most preferably from 75% to 100% according to the method described herein.
    The opacity of a sheet material shows the degree of non-transparency of the sheet material. When a sheet material has an opacity of 0%, the sheet material is completely transparent. On the other hand, when a material has an opacity of 100%, the sheet material has no transparency, i.e. no light is transmitted through the material. The opacity of the wrapping sheet shows the extent to which how clearly the absorbent article packaged individually by a wrapping sheet can be seen through the wrapping sheet.
    The wrapping sheet (i.e. wrapping sheet) forming the pouch is generally printed on its outer surface in accordance with the process described herein. The print typically includes not only colors but also indications and / or elements that form a scene and / or offer a part of a story.
    In a further aspect, the current disclosure relates to a series of pouches () each comprising a wrapping sheet () for incorporating a single personal hygienic
    BE2017 / 0134 absorbent article wherein each said pouch () comprises an inner surface facing the personal hygienic absorbent article and an outer surface opposite, the outer surface including a printed indication and arranged so that when many of said pouches in said series are side by side stacked, they form at least a single, essentially harmonious image.
    In a preferred embodiment, the substantially harmonious image is arranged to provide a story and / or theme that provides a visual sensory trigger for the comfort, performance and / or intended use of said personal hygienic absorbent articles.
    In yet another preferred embodiment, the clothing surface of the absorbent article has a first inspection treatment, while the wrapping sheet has a second inspection treatment.
    In one embodiment, the first and second test treatment produces first and second colors selected from one color system. More specifically, in preferred embodiments, the clothing surface of the absorbent article and the wrapping sheet have first and second test treatments that produce first and second primary colors, respectively, selected from a color system selected from a group consisting of a blue color system, a pink color system, a green color system, an orange color system and a yellow color system.
    The wrapping sheet is preferably manufactured from a thin flexible material. The wrapping sheet material is preferably liquid impermeable so that the wrapping sheet is suitable for packaging and removing a used sanitary napkin. In preferred embodiments, the wrapping sheet is in the form of a film or a non-woven net or a film laminated with a non-woven net.
    Preferred matierals for the sheath sheet of the present disclosure typically include a thermoplastic polymer, a pigment, and a filler (inorganic or organic). The materials for the pigment or filler are typically in the form of a particle. Such particles are dispersed in the thermoplastic polymer. Pigments or fillers preferably contain no more than about 20% of a film. (If desired, the particles of the pigment or filler can be coated with a fatty acid ester to achieve a higher loading in the polymer.) In preferred embodiments, the optical properties of the envelope sheet, i.e. the opacity.
    Suitable thermoplastic polymers include polyolefin such as polyethylene (PE), including a low density polyethylene (LLDPE), a low density polyethylene (LDPE), a very low density polyethylene (ULDPE), a high density polyethylene (HDPE), a polypropylene and a mixture thereof. Other suitable thermoplastic
    BE2017 / 0134 polymers that can also be used include, but are not limited to, a polyester, a polyurethane, a compostable or biodegradable polymer, a thermoplastic elastomer, and a matailocene catalyst. The material for the filler is preferably an inorganic material selected from the group consisting of a titanium dioxide, a zinc oxide, a calcium carbonate, a mica and a mixture thereof. Alternatively (or if desired) the material for the filler may be an organic material such as a high-density polyethylene or another organic polymeric material such as a polypropylene.
    In a production process, the thermoplastic polymer, filler and pigment are mixed or mixed together to form a homogeneous mix in a suitable mixing extrusion or in a separate preliminary preparation step. The mixture is then poured or blown into a film or a non-woven net.
    In alternative preferred embodiments, the optical properties of the envelope sheet can also be controlled by changing the types and amount of ingredients of the ink (s) to be used for printing on the surface of the envelope sheet material.
    Printing of indications and / or graphic images on the envelope sheet (s) can be done by any conventional printing method known in the art such as gravure printing, flexographic printing, letterpress printing, offset printing, inkjet printing and the like, most preferred for flexographic printing, customary using the CMYK (cyan, magenta, yellow, and key (ie black) color model. A printing ink typically contains about 20-60% of a binder resin or filler, about 40-60% of a pigment (or colorant) and additives such as process aids that typically used for drying up solvents after a printing process.
    The amount of filler influences the opacity level of the wrapping sheet. Increasing the filler material, for example, makes the resulting material more transparent, while lowering the filler material makes the resulting material more transparent. Thus, in preferred embodiments, the level of opacity of the wrapping sheet material is controlled by the change in the amount of fillers contained in the wrapping sheet material.
    The optical properties of the wrapping sheet are also controlled by changing the types and amount of ingredients of the ink (s) to be used for printing on the surface of the wrapping sheet material. In order to increase the level of opacity, an ink is preferably used which comprises inorganic pigment (s) such as titanium dioxide,
    BE2017 / 0134 zinc oxide, a zinc oxide, a calcium carbonate and the like. Such inorganic pigment (s) can offer higher opacity by increasing the amount thereof. The particle size of an inorganic pigment can vary depending on the printing method to be used. In a preferred embodiment, a titanium dioxide is preferably used as the pigment.
    In one embodiment, a wrapping sheet has a test treatment that produces a primary color by dyeing, i.e., the addition of a pigment to the film ingredients. The pigment must be selected depending on the intended inspection treatment. A suitable selection of a pigment contributes to the production of a wrapping sheet with an expected non-white color (e.g., blue, red, yellow, green, gray, etc.).
    In an alternative embodiment, the envelope sheet has a test treatment that produces a primary color by printing on a colored or substantially non-colored envelope sheet.
    The wrapping sheet with a test treatment can also be produced by changing the types and amount of ingredients of the ink (s) to be used for printing the surface of the wrapping sheet material.
    A sanitary napkin 122 of the disclosure is packaged by wrapping sheet 3. In one embodiment, a folded (or non-folded, if desired) sanitary napkin is placed in a pouch formed by said wrapping sheet. Such a pouch is typically formed by forming and sealing the edges of the wrapping sheet.
    The wrapping sheet and the sanitary napkin are preferably folded around two folding lines (if desired, the number may be more than one or three) to provide an individually packaged structure for the sanitary napkin.
    In a preferred embodiment, each pouch (or envelope / package / wrap) comprises a resealable attachment 7 arranged to keep the pouch in a closed state and / or to be able to reseal the pouch with a used product for removal thereof.
    Individually packaged sanitary napkins each encased in a wrapping sheet are preferably stacked, compressed, and enclosed in a package (i.e., a container) such as a polymer film or carton box bag.
    THE HOLDER
    According to the announcement, holder 4 comprises a plurality of individually packaged personal hygienic absorbent articles, with each personal hygienic absorbent article
    BE2017 / 0134 is packaged in a pouch formed by a printed wrapping sheet 3, each pouch includes an inner surface facing the personal sanitary absorbent article and an outer surface opposite it, the outer surface including printed indicia thereon and arranged so that when many of said pouches in the holder are stacked side by side until they form at least a single substantially harmonious image and wherein at least a portion of said pouches are visible through said holder.
    In a preferred embodiment, the container consists of a transparent bag which preferably comprises one or more printed zones with one or more colors that result in an opacity of more than 50%, preferably greater than 60% and at least one non-printed zone with an opacity of less than 25% Preferably, at least one of the colors is substantially the same as one of the colors present on each of the individual packaged articles (or pouches).
    In an alternative embodiment, the holder consists of a cardboard box that has a substantially transparent or transparent window through which at least a portion of the individually packaged articles can be viewed from outside said holder.
    METHOD FOR MAKING
    According to the announcement, the process for making individually packaged personal hygienic absorbent articles includes the following steps:
    (i) providing a single image 1 with a width (W) and a length (L) and comprising one or more, preferably, a plurality of indications 2 with at least one of the indications 2 being repeated more than once within said image 1.
    (ii) printing a plurality of said single images over a continuous film and / or net of material to form a continuous repetition of the same single image in a side-by-side arrangement with a length (L) of the image which extends along the length of the continuous film and / or mesh of material and the width (W) of the image corresponding to the width of said film and / or mesh of the material.
    (iii) cutting printed film and / or net material along a transverse axis perpendicular to said length (L) so as to form a plurality of individual segments of a film and / net material, to form individual wrapping sheets 3 that form a portion of said single image 1 and so adapted to fit each of said personal hygienic absorbent article.
    BE2017 / 0134 (iv) packaging of individual personal hygienic absorbent articles each with one of said wrapping sheets 3 in such a way that a printed portion of the wrapping sheet 3 can be viewed.
    (v) stacking a plurality of individually packaged personal hygienic absorbent articles in container 4.
    wherein said image is free from demarcation lines extending perpendicular to the length (L) and parallel to the width (W) of said image and wherein said stacked plurality of individually packaged personal hygienic absorbent articles when unpacked and / or side by side positioned mainly called single image reconstructing. It has been established that the creation of images and landscapes without demarcation lines enables a cutting operation that does not require a predetermined position of cutting (e.g., via registered cutting step) and thus greatly simplifies the process, which in turn ensures that when individual sheaths are stacked, they still recreate the original image without the risk of having vertical lines that would distract and / or break the continuous story.
    In one embodiment, the wrapping sheet of each of the stacked plurality of the individually packaged personal hygiene absorbent articles within the container has a common theme.
    In a preferred embodiment, the cutting step is not registered.
    In one embodiment, each of the wrapping sheets of the plurality of individually packaged personal hygiene absorbent articles stacked in the container provides a portion of a story that progresses from one wrapping sheet to another, typically starting from a first wrapping sheet proximal to an aperture of said container on a final wrapper sheet distorting said aperture, preferably wherein said story is contained in its entirety in said single image. Without wishing to be bound by theory, it is further believed that creating such an additional sensory experience for especially sanitary items of the sanitary napkin type, distract users from the melancholic mood during the menstrual period and rather further improved perception of performance and attention to detail, as well as curiosity and interaction with the product that may be particularly beneficial to teenagers who eat such products use rst.
    In one embodiment, the printing step comprises printing the images with at least four colors, preferably more than four colors (preferably more than five, more preferably more than six, even more preferably at least eight) but generated from the CMYK (cyan, magenta), yellow and key (ie black)) color model.
    BE2017 / 0134
    In one embodiment, the printing step comprises printing four superimposed sub-images, each from one of the colors selected from cyan, magenta, yellow, and black to generate the single image. This has the advantage that multiple colors (four or more) can be printed on the pouches in a fast and effective process that can be implemented in both an in-line and batch process.
    In one embodiment, at least one of the indications on each of the plurality comprises individually packaged personal hygiene absorbent articles. This has the advantage that a coherent theme is carried out between the pouches in a holder.
    In a preferred embodiment, the plurality of indications of the image are skewed along an axis parallel to the width (W), preferably wherein each indication 2 has a centerline C and each said centerline is separated by a distance (d1, d2) along said axis . In one embodiment, each distance (d1, d2) is substantially the same, in an alternative embodiment, each distance (d1, d2) is different. An advantage of such an arrangement is that it makes it possible to have a cutting process step that does not have to be registered and still has to ensure that each generated pouch comprises at least one complete designation. This also has the advantage that it reduces the complexity of the process and costs.
    The distance (d1, d2) is preferably greater than or equal to a second distance separating a cutting and sealing station and / or wherein the distance (d1, d2) is from 90 mm to 150 mm, preferably from 95 mm to 140 mm, more preferably from 110 mm to 130 mm.
    TEST METHODS
    Opacity:
    A dispersion color meter is preferably used to determine the opacity of a sample material. A preferred dispersion milk color meter is available from BYKGardner GmbH, Geretsried, Germany, under the trade name BYK Gardner Color-Guide 45/0 (Cat.
    No. 6800).
    The measurements must be carried out using a light source A with a viewing angle of 2 ° (degrees). This dispersion color meter contains a light source for light source A (that is, an estimate of an incandescent lamp with a correlated color temperature of approximately 3000 K), a
    BE2017 / 0134 flat table, a white standard plate, a standard black plate, a photo detector with a multi-sensor diode array with cells with a photo detector and a computer. The white and black standard plates are available from the same company under Cat. Nos. 6811 and 6810, respectively. The white standard plate is placed on the flat table during the measurement. A sample material is placed on the white standard plate in a flat condition. The sample material is illuminated by the light source with an angle of incidence of 45 °. The reflection light that is reflected by the sample material is received by the photo detector with a recording angle of 0 °. The reflection speed (Yw) of the reflection light is detected by the photo detector. Similarly, after the black standard plate is placed on the flat table, the sample material is placed on the black standard plate in a flat state. The sample material is illuminated by the light source with an angle of incidence of 45 °. The reflection light that is reflected by the sample material is received by the photo detector with a recording angle of 0 °. The reflection speed (Yb) of the reflection light is detected by the photo detector. The coverage (OP) is obtained by the following formula:
    OP (%) = (Yb / Yw) x 100 - (1)
    This process is repeated at least five times for one sample material and the average value of the measured opacity (OP) is calculated and recorded by the color meter. The average value of the measured opacity is called the coverage of a sheet of material.
