Description

Technical Field

[0001] The present disclosure relates to a package comprising a bag and at least two absorbent articles arranged in the bag, such as disposable personal hygiene absorbent articles in the form of incontinence guards, sanitary napkins, panty liners, diapers and the like. Background Art

[0002] Disposable personal hygiene absorbent articles, such as diapers or absorbent pads such as incontinence guards or sanitary napkins, are usually provided with multiple packages comprising one or more product stacks arranged in a plastic bag. Although plastic materials are versatile and provide a series of advantages, such as low weight, high flexibility and easy sealing, plastic packaging materials may also be associated with shortcomings such as low degradability and recyclability, generation of toxic gases during combustion, littering, etc. Therefore, efforts are currently being made to replace plastic packaging by more sustainable and / or renewable substitutes (such as paper materials). Summary of the invention

[0003] It is an object of the present disclosure to provide, in at least some aspects, an improved package comprising a bag and at least two absorbent articles. This object is achieved by a package according to claim 1 .

[0004] Therefore, a package is provided comprising a bag and at least two absorbent articles arranged in the bag, wherein the bag is made of a paper material. The absorbent article may be a disposable personal hygiene absorbent article, such as an incontinence guard, a sanitary napkin, a panty liner, a tampon, a diaper, or the like.

[0005] Disposable hygiene articles such as sanitary napkins, panty liners and the like are generally intended to absorb body fluids such as urine and blood.

[0006] Disposable diapers can be pant diapers, open diapers (also known as integrated diapers or belt-type absorbent products) that allow the wearer or caregiver to apply the diaper in a standing position. Diapers can be diapers for infants, young children or adults.

[0007] Belt-type absorbent products, i.e. belt products, typically have a belt integrally attached to the base of the absorbent product. The belt may have two belt portions extending on either side of the rear end of the base. The two belt portions are intended to be fastened around the waist of the wearer, while the front end of the absorbent section hangs down between the legs of the wearer. Once the belt portions have been attached together by fasteners or, for example, fastening tabs, the wearer can reach between his or her legs to pull up the absorbent section between the legs and attach the free end of the absorbent section to the belt portion by a second fastener, such as a fastening tab. Similarly, the product can be made so that the belt is fastened to the front of the product and is fixed around the back of the wearer. In this case, the absorbent section will hang down in the front and will be fixed to the belt at the back. This type of product is particularly useful for caregivers who are caring for patients who may suffer from dementia or the like.

[0008] The term "disposable" is used to describe absorbent products that are not generally intended to be laundered or otherwise restored or reused as absorbent products, e.g., they are intended to be discarded after a single use and may also be configured to be recycled, composted, or otherwise disposed of in an environmentally compatible manner.

[0009] The absorbent article may optionally be a reusable and washable absorbent article, such as a washable and reusable sanitary article, such as a sanitary napkin, a panty liner, or the like, or a washable and reusable absorbent underwear for urine, vaginal fluid and / or menstrual fluid, or a diaper for urine and feces. Washable and reusable diapers may be fully washable, or diapers having a washable outer shell adapted to receive an absorbent assembly, which may be a reusable absorbent assembly or a disposable absorbent assembly.

[0010] Preferably, the absorbent article may be an absorbent pad, such as an incontinence guard, a sanitary napkin or a panty liner.

[0011] Bag has sealed bottom, top seal and the peripheral wall extending between bottom and top seal.The peripheral wall comprises front wall, opposite rear wall and the first side wall and the second side wall connecting front wall and rear wall.The peripheral wall also comprises the first top surface extending between top seal and front wall, and the second top surface extending between top seal and rear wall.The top seal has been formed by adhering the inner surface top part of the peripheral wall to each other.The packaging also comprises at least one adhesive patch, which is configured to keep the top seal folded onto one of the first top surface and the second top surface.The at least one adhesive patch can be, for example, a sticker or an adhesive tape.The at least one adhesive patch can have any suitable shape, such as rectangle, square, oval, oblong, triangle, circle, etc.

[0012] Packaging according to the present disclosure has a gable top, which is realized by adhering the inner surface parts of the peripheral wall to each other after filling the bag with absorbent articles.By providing an adhesive patch that keeps the top seal folded onto one of the first top surface and the second top surface, the packaging can present the basic shape of a rectangular block, that is, with a flatter top than originally.From the perspective of packaging, this is advantageous because the packaging with a flatter top is more stable when stacked on each other on the one hand, and occupies less space on the other hand.In addition, when the top is flattened by at least one adhesive patch, the packaging is not easily damaged.Otherwise, damaged packaging may be a problem that occurs when moving from a plastic packaging material to a paper material, because paper materials are usually more fragile and less flexible than plastic packaging materials.

[0013] Furthermore, the packaging disclosed herein achieves the above advantages without having to use hot melt adhesive to attach the top seal to the top surface, such as by applying a hot melt adhesive dot to one of the surfaces and pressing the other surface onto it. In this way, production technology problems associated with the application of hot melt adhesive and problems associated with the recycling of paper materials including hot melt adhesive are reduced.

[0014] Adhesive patch is also conducive to providing additional sealing at the weak part of top seal. This weak part with sealing integrity problem may occur in the middle part of top seal in the area between opposite "wings" or fins of gable top. This may be due to the uneven thickness of top seal when the inner surface part of peripheral wall is sealed to each other after filling bag with absorbent articles. Top seal can be realized by pressing two sealing strips against each other, wherein the inner surface part of peripheral wall is adhered to each other between sealing strips. Adhesive (such as hot melt adhesive) applied to bag melts and attaches surface parts to each other and forms top seal. Due to uneven thickness (it depends on the outer size of bag), weak part may be produced. Adhesive patch can be positioned to cover weak part on top seal, that is, the middle between first side surface and second side surface of bag.

[0015] Alternatively, the at least one adhesive patch comprises a non-sticky front surface and a rear surface, wherein the adhesive layer is arranged on at least a portion of the rear surface. The adhesive layer can cover the rear surface as a whole, or it can only cover a part of the rear surface so that a non-sticky portion is provided, such as for gripping the adhesive patch to remove it. Adhesive can also be distributed discontinuously on the rear surface, such as, as a line of strip form or spiral pattern. Strip or spiral can be at a certain distance or overlap each other. Adhesive is not limited to being distributed as a line. As an alternative, it can be distributed as a point or an island, wherein adhesive is regularly or irregularly distributed on the rear surface, as long as enough adhesion is achieved. The peel strength should be high enough to be maintained in a folded configuration by packaging, but will not be high enough to exceed the tensile strength of the bag.

[0016] The front surface may include a decorative surface, such as a printed surface.

[0017] The adhesive patch may also have embossing. The embossing may be made to give the adhesive patch a nice appearance. The embossing may also be an aid to the visually impaired and blind who will use the product within the package. For example, a portion of the adhesive patch may have embossed alphabetic symbols representing letters of the conventional Roman alphabet or embossed numerical symbols representing conventional Arabic numerals or other symbols, showing, for example, the absorption capacity with an embossed droplet, or a symbol indicating where to open the package.

[0018] Optionally, the first part of the at least one adhesive patch is adhered to the top seal, and the second part of the at least one adhesive patch is adhered to one of the first top surface and the second top surface on which the top seal is folded, and / or adhered to one of the front wall and the rear wall. Therefore, at least the second part of the at least one adhesive patch is used to keep the top seal folded onto the top surface. Preferably, the at least one adhesive patch has an elongated shape, and its long side extends perpendicular to the top seal. Preferably, when a single adhesive patch is provided, it can be positioned at a midway position between the first side surface and the second side surface of the bag to cover the potential weak area of ​​the top seal. The length of the at least one adhesive patch can be selected so that the at least one adhesive patch is adhered to one of the top surface and the adjacent one of the rear wall and the front wall, or so that the at least one adhesive patch is only adhered to the top surface on which the top seal is folded. Of course, the first part of the at least one adhesive patch can also extend to the other of the first top surface and the second top surface. Optionally, the at least one adhesive patch can extend from the rear surface all the way, across the second top surface, the top seal and the first top surface, and extend to the front surface. Depending on the length of the top seal, the at least one adhesive patch can extend from the top seal to the front surface or the rear surface, or extend from the rear surface all the way, across the second top surface, the top seal and extend to the front surface. In other words, the folded top seal can partially or completely overlap with the first or second top surface. It may even be the case when the folded top seal partially overlaps with the front surface or the rear surface. If the at least one adhesive patch has embossing, it can be arranged on the second part. The embossing can then reduce the adhesion of the second part to the package and make it easier to open.

[0019] Optionally, a first portion of the at least one adhesive patch is adhered to the top seal and a second portion of the at least one adhesive patch is adhered to one of the first side wall and the second side wall. In this case, the at least one adhesive patch preferably has an elongated shape with a long side extending parallel to the top seal along the first portion of the at least one adhesive patch.

[0020] Optionally, a third portion of the at least one adhesive patch is adhered to the other of the first side wall and the second side wall. In this case, the adhesive patch has an elongated shape, wherein the first portion extends along the top seal, the second portion is attached to one of the first side wall and the second side wall, and the third portion is attached to the other of the first side wall and the second side wall.

[0021] In the above-mentioned embodiment, the same adhesive can be used for the adhesive layer in the first part, the second part and the third part (if applicable) of the at least one adhesive patch. In this case, the area of ​​the first part attached to the top seal is preferably greater than the area of ​​the second part and / or the third part, so that the risk of the at least one adhesive patch being released from the top seal is less than the risk of releasing from another surface of the bag associated with the opening. Optionally, the first part can use an adhesive different from the second and / or third part. The first part can include following adhesive: this adhesive firmly attaches the at least one adhesive patch to the top seal of the bag. Then, the second part and / or the third part can include an adhesive that forms a releasable bond with another surface of the bag.

[0022] Optionally, the at least one adhesive patch includes a non-adhesive gripping portion, which is configured to be gripped by a user to release at least the second portion of the at least one adhesive patch from the bag. The gripping portion is preferably positioned adjacent to the second portion of the at least one adhesive patch and / or adjacent to the third portion of the at least one adhesive patch. Therefore, the at least one adhesive patch can remain attached to the bag while allowing the bag to be opened.

[0023] Optionally, the at least one adhesive patch includes a first adhesive patch and a second adhesive patch. Therefore, at least two adhesive patches are provided. The second adhesive patch may have the same characteristics as the first adhesive patch. In some cases, the second adhesive patch may have a shape different from the first adhesive patch. By using two adhesive patches, the flatness of the top can be improved.

[0024] Alternatively, the first adhesive patch is attached to the top seal near the first sidewall, and the second adhesive patch is attached to the top seal near the second sidewall. "Near the first sidewall" means in this article that the first adhesive patch is positioned between the first sidewall and the middle part of the top seal midway between the sidewalls. "Near the second sidewall" means that the second adhesive patch is positioned between the middle part of the second sidewall and the top seal. Therefore, the first adhesive patch and the second adhesive patch are preferably spaced apart. This configuration is advantageous for the packaging with a relatively long top seal.

[0025] Alternatively, the adhesive layer is a self-adhesive layer, i.e., a layer that does not require wetting to bond. The adhesive layer may include any suitable adhesive that provides desired peel strength, rapid adhesion, releasability from packaging, and coating weight properties. For example, the adhesive may be a hot melt adhesive that is applied to the backing material of the adhesive patch by any known hot melt coating process.

[0026] The peel strength of the adhesive patch should be high enough to hold the package in the folded configuration, but not so high as to exceed the tensile strength of the bag or landing member disposed thereon to ensure good resealability.

[0027] The adhesive may be a bio-based adhesive. It may also be a biodegradable adhesive. It may be made from renewable resources and / or may be compostable.

[0028] If the first paper material, such as a bag, is very thin, the package may be provided with a landing member (or "landing surface"). The landing member may have an adhesive surface, which is the surface to which the adhesive of the adhesive patch is resealably adhered.

[0029] The properties of the entire fastening system, including the properties of the adhesive on the adhesive patch and the properties of the landing member or paper material, are important design criteria for the performance of the packages disclosed herein. The fastening system needs to provide a joint that can be opened to remove the absorbent article for use by the wearer without destroying or damaging the landing surface or paper bag, and preferably a joint that is also refastenable.

[0030] Optionally, the self-adhesive layer is configured to allow the bag to be resealed by the at least one adhesive patch. Therefore, the self-adhesive layer includes a resealable adhesive. In this way, the user can easily reseal the package so that it obtains a compact shape after removing the absorbent article. Since paper material packaging is usually larger and harder than plastic packaging, they tend to rebound when folded down after opening. By using a self-adhesive layer that allows resealing, it is conducive to compacting the package after opening to occupy less space, and better protection of the absorbent article therein can be achieved. This is particularly important in a package comprising two absorbent products stacked, because excess material may be retained after the upper stack is used up.

[0031] As used herein, "resealable adhesive" refers to an adhesive that allows an object to be attached to a surface using such adhesive and subsequently detached from the surface, resulting in little or no damage to the object and the surface. In addition, the object that has been detached can be reattached to the surface again.

[0032] The resealable adhesive may be a pressure sensitive hot melt adhesive. Such an adhesive provides an unlimited open time, which means that the resealable adhesive can be bonded to another substrate at any time. Such a resealable adhesive may provide "Post-it-like" adhesive properties. Thus, the package may be reclosable. Therefore, the pressure sensitive hot melt adhesive used with the package is an adhesive that has very high self-adhesive properties but can be easily separated or released from other materials.

[0033] Optionally, when the at least one adhesive patch holds the top seal folded onto one of the first and second top surfaces, the top seal together with the first and / or second top surfaces of the package forms a flat or substantially flat surface extending parallel to the sealed bottom. A brick-like package is thereby provided that is easy to pack and transport in a multi-pack comprising several packages within a larger box.

[0034] Optionally, the at least one adhesive patch comprises a backing material in the form of a second paper material.

[0035] Alternatively, the backing material of the at least one adhesive patch, that is, the material on which the adhesive layer is provided, can be any type of backing material well known in the art. For example, polyester film, polypropylene film, paper backing or other materials providing required strength to be used as a part of an adhesive patch are suitable for use as backing material, and the adhesive patch is used to maintain packaging in a folded configuration before unpacking, and to maintain packaging in a folded configuration after unpacking for storage. The backing material can be a bio-based material. It can also be a biodegradable material. It can be made from renewable resources and / or can be compostable.

[0036] Optionally, the first paper material of the bag has a density of 50 to 90 g / m 2 The paper material having a basis weight within this range is thick and strong enough to provide accurate protection of the absorbent pad within the bag against environmental contamination, and can also withstand the stress generated during the formation of the bag and the loading of the absorbent pad into the bag. The paper material can be a single layer (one sheet) or multiple layers.

[0037] Mention paper material, that is, when referring to the first paper material and the second paper material, it is understood herein that the material is produced by pressing wet fibers together, dehydrating the fibers and drying them into a preferably flexible sheet. The paper material can be an unbleached paper material or a bleached material. The fiber can be pulp fiber from chemical pulp (e.g., kraft, sulfate or sulfite), mechanical pulp, thermomechanical pulp, chemical mechanical pulp and / or chemical thermomechanical pulp (abbreviated as CTMP). Pulps derived from deciduous (hardwood) and coniferous trees (softwood) can be used. Therefore, the fiber can be a natural fiber from wood, such as cellulose-based fibers, bamboo-based fibers, etc. Natural fibers can also be non-wood fibers, such as cotton, abaca, kenaf, sabe grass, flax, serrata, straw, jute, bagasse, milkweed fibers and pineapple leaf fibers. The paper material can be made of a mixture of one fiber or different fibers. The paper material can also be treated in a way that better retains moisture, such as having a plastic layer inside or outside. The paper can be a smooth paper that has been calendered. The paper may be a paper having a low porosity.The paper material may comprise recycled or virgin fibers or a combination thereof.

[0038] Optionally, the sealed bottom of the bag is formed by folding and adhering a portion of the paper material to form a flat and rectangular bottom. The sealed bottom can advantageously be formed using overlapping seams, thereby providing a flat bottom. The bottom can preferably be a block bottom or a pinch bottom or any other type of bottom.

[0039] Personal hygiene absorbent articles can be used to absorb body exudates, such as blood, urine, sweat and feces. These personal hygiene absorbent articles can be individually packaged in a bag set so that the article remains clean and intact before use. However, two or three or more personal hygiene absorbent articles can also be provided in the bag set, which may be suitable for carrying and using during the day. The bag set can be a bag set in which the article and the bag set material are folded together before the side edges (i.e., edge regions) are sealed, or a pocket in which the folded article is inserted into the pocket before the pocket is sealed. Independent packaging is convenient for carrying a single article hygienically for future use, such as in a handbag. In addition, the packaging unit is usually used as a device for packaging unused articles and as a device for disposing of used articles.

[0040] Optionally, the at least two absorbent articles are arranged as at least one absorbent article stack. In this case, the absorbent article may be, for example, an incontinence guard, a sanitary napkin, a panty liner, a diaper, etc. The at least one absorbent article stack may be at least one uncompressed absorbent article stack. Optionally, the at least one absorbent article stack may be a compressed absorbent article stack. The absorbent article stack comprises at least two absorbent articles. By way of example only, and in particular when the bag comprises two article stacks, the stack may comprise 8 or 10 absorbent articles. However, the stack is not limited to 8 or 10 articles. Therefore, each stack may comprise more than 10 or less than 8 articles. When a single absorbent article stack is provided in the bag, the stack may comprise a greater number of articles, such as 15-25 absorbent articles, for example 16 or 20 absorbent articles.

[0041] Optionally, each of the at least one absorbent article stack comprises a plurality of folded and individually wrapped absorbent articles. Optionally, each of the at least one absorbent article stack may comprise a plurality of folded absorbent articles without individual wrappings. In both cases, the absorbent articles may be folded once or twice so that each folded absorbent article is folded into two or three folded layers. One or more folds may preferably be arranged parallel to the peripheral wall of the bag, i.e. perpendicular to the bottom of the bag. Alternatively, one or more folds may be arranged parallel to the bottom of the bag.

[0042] The folded absorbent article may have a width of 110-130 mm and a length of 70-95 mm.

[0043] Optionally, the at least one absorbent article stack includes two absorbent article stacks. The two absorbent article stacks may be a bottom stack located in the bottom of the bag and a top stack located in the top of the bag. In some embodiments, the at least one absorbent article stack may include more than two absorbent article stacks, such as four absorbent article stacks. For example, two bottom stacks and two top stacks may be provided, wherein the first bottom stack and the first top stack are located closer to the first side wall, and wherein the second bottom stack and the second top stack are located closer to the second side wall.

[0044] Optionally, the at least one stack of absorbent articles comprises a single stack of absorbent articles.

[0045] Optionally, the bag is opaque and the absorbent article, such as a package of individually wrapped absorbent articles or absorbent articles, cannot be seen through the bag. Therefore, the information printed on the package can be clearly visible to the user. Of course, the article in the bag can be an unwrapped article, such as a diaper or an unwrapped pad.

[0046] Optionally, the absorbent article is a disposable absorbent article such as a diaper, or an absorbent pad such as an incontinence guard or a sanitary napkin, or a washable and reusable absorbent article.

[0047] Further advantages and advantageous features of the invention are disclosed in the following description and in the dependent claims. BRIEF DESCRIPTION OF THE DRAWINGS

[0064] Various aspects of the disclosure will be described below in conjunction with the drawings to illustrate rather than limit the disclosure, wherein like reference numerals represent like elements, and variations of the described aspects are not limited to the specifically illustrated embodiments but are applicable to other variations of the disclosure.

[0065] A package 1 according to an embodiment of the present disclosure is schematically shown in FIGS. 1-6 . In the illustrated embodiment, the package 1 comprises a bag 100 and two stacks 201 , 202 of absorbent articles 300 in the form of absorbent pads 300 arranged in the bag 100. The top stack 201 is arranged on top of the bottom stack 202. The bag 100 is made of a first paper material and has a sealed bottom 101 , a top seal 170 and a peripheral wall 103 extending between the bottom 101 and the top seal 170. The peripheral wall 103 comprises a front wall 104, an opposite rear wall 105 and first and second side walls 106 , 107 connecting the front wall 104 and the rear wall 105. The peripheral wall 103 also comprises a first top surface 171 extending between the top seal 170 and the front wall 104, and a second top surface 172 extending between the top seal 170 and the rear wall 105. The two top surfaces 171, 172 together with the top seal 170 form the sealed top 102 of the package 1. The top seal 170 includes a forward facing first outer surface 170a directly connected to the first top surface 171, and a rearward facing second outer surface 170b directly connected to the second top surface 172.

[0066] The package 1 further comprises at least one adhesive patch 400 configured to retain the top seal 170 folded onto one of the first top surface 171 and the second top surface 172. Figure 1a-1b In the embodiment shown, a single adhesive patch 400 is provided, which comprises a non-adhesive front surface 401 and a rear surface 402. On the rear surface 402 an adhesive layer is provided. Figure 1a The package 1 is shown with the top seal 170 in a sealed but unfolded state, with the adhesive patch 400 attached only to the first outer surface 170a of the top seal 170 . Figure 1bThe package 1 is shown with the top seal 170 in a sealed and folded state, with the first portion 403 of the adhesive patch 400 adhered to the first outer surface 170a of the top seal 170, and the second portion 404 adhered to the second top surface 172 onto which the top seal 170 is folded, and further reaches onto and adheres to the rear wall 105. Of course, the top seal 170 may alternatively be folded onto the first top surface 171, in which case the first portion 403 would adhere to the second outer surface 170b of the top seal 170, and the second portion 404 of the adhesive patch 400 would adhere to the first top surface 171 and the front wall 104. In some embodiments, the adhesive patch 400 may have another shape and may not reach all the way onto the front wall 104 or the rear wall 105. In addition, in some embodiments, the first portion 403 of the adhesive patch 400 can reach the top surface 171 connected to the outer surface of the top seal 170 (to which the first portion 403 of the adhesive patch 400 is adhered), and optionally reach all the way to one of the rear wall 105 and the front wall 104 connected thereto.

[0067] like Fig. 9 As shown, the bag 100 is formed from a single rectangular sheet of paper 110 that is folded, glued, and cut to form the bag 100. Once the bottom 101 and peripheral wall 103 of the bag 100 have been formed and sealed, and the bag 100 has been filled with the absorbent pad 303, the bag 100 is folded and sealed at the top 102 to form the top seal 170, and the top seal 170 is cut out. Fig. 9 Excess top portion 109 above cut line 108 is shown.

[0068] The top seal 170 has been formed by folding and adhering the inner surface top portions of the paper sheets 110 to each other to form wings or fins. Fig. 9 A rectangular sheet 110 is shown with a first side facing outward, wherein the first side will form the outside of the bag 100 after folding and sealing. The inner surface top portion is disposed on the second side of the sheet 110, which will form the inside of the bag 100 after folding and sealing. The location of the inner surface top portion (although disposed on the second side) is Fig. 9The inner surface top portion includes: the first top portion 113 of the first top surface 171 and the adjacent first top portion 123 of the second side wall 107; the second top portion 114 of the first top surface 171 and the adjacent first top portion 124 of the first side wall 106; the first top portion 115 of the second top surface 172 and the adjacent second top portion 125 of the second side wall 107; the second top portion 116 of the second top surface 172 and the adjacent second top portion 126 of the first side wall 106; the third top portion 117 of the front wall 104, located between the first top portion 113 and the second top portion 114 of the first top surface 171; and the third top portion 118 of the second top surface 172, located between the first top portion 115 and the second top portion 116 of the second top surface 172.

[0069] The first top portion 113 of the first top surface 171 is adhered to the adjacent first top portion 123 of the second side wall 107 to form a first adhered portion 111 having a first length L1, such as Figure 2 and Fig. 9 As shown. The second top portion 114 of the first top surface 171 adheres to the adjacent first top portion 124 of the first side wall 106 to form a second adhered portion 112 having a second length L2. The first top portion 115 of the second top surface 172 adheres to the adjacent second top portion 125 of the second side wall 107 to form a third adhered portion 121 having a third length L3. The second top portion 116 of the second top surface 172 adheres to the adjacent second top portion 126 of the first side wall 106 to form a fourth adhered portion 122 having a fourth length L4. The third top portion 117 of the first top surface 171 adheres to the third top portion 118 of the second top surface 172 to form a fifth adhered portion 130 having a fifth length L5. The fifth length L5 is less than each of the first length L1, the second length L2, the third length L3, and the fourth length L4. The lengths L1 , L2 , L3 , L4 , and L5 are all measured in a direction parallel to the front wall 104 in a state in which the adhered portions 111 , 112 , 121 , 122 , 130 are stretched out as much as possible.

[0070] In the illustrated embodiment, the first length L1, the second length L2, the third length L3 and the fourth length L4 are all equal within manufacturing tolerances. The fifth length L5 is less than 75% of each of the first length L1, the second length L2, the third length L3 and the fourth length L4 in this article, preferably less than 65% or less than 60%. The first length L1, the second length L2, the third length L3 and the fourth length L4 can be between 30-50mm, preferably 35-45mm. The fifth length L5 can be 1-30mm, more preferably 3-25mm. The total length L of the front wall 104 and / or the rear wall 105 of the bag 100 measured between the side walls 106, 107 at the bottom of the package 1 tot Substantially equal to the sum of the first length L1 , the second length L2 and the fifth length L5 and / or the sum of the third length L3 , the fourth length L4 and the fifth length L5 .

[0071] In the embodiment shown, the first length L1 is 39 mm and the fifth length L5 is 22 mm, ie, 56% of the first length L1. In the embodiment shown, the bag 100 has an overall length L1 measured between the side walls 106, 107 of 100 mm. tot , and an overall width W of 78 mm measured between the front and rear walls 104, 105. The filling height H of the bag 100 is 163 mm in the embodiment shown.

[0072] In another embodiment, the first length L1 is 45 mm and the fifth length L5 is 10 mm, which is 22% of the first length L1. The bag 100 has an overall length L measured between the side walls 106, 107 of 100 mm. tot , and an overall width W of 88 mm measured between the front and rear walls 104, 105. The filling height H of the bag 100 is 165 mm in the embodiment shown.

[0073] like Figure 2As best shown, the fifth adhesive portion 130 connects the first and third adhesive portions 111, 121 disposed closer to the second side wall 107 to the second and fourth adhesive portions 112, 122 disposed closer to the first side wall 106. Thus, the first and third adhesive portions 111, 121 form a first pair of wings, and the second and fourth adhesive portions 112, 122 form a second pair of wings. None of the adhesive portions 111, 112, 121, 122, 130 is adhered to another adhesive portion 111, 112, 121, 122, 130 by, for example, overlapping seams or butt seams. In addition, none of the adhesive portions 111, 112, 121, 122, 130 is directly adhered to an outer surface portion of the peripheral wall 103. Since they are not adhered to any outer surface portion of the peripheral wall 103, the first, second, third, and fourth adhesive portions 111, 112, 121, 122 form suitable gripping members for opening the bag.

[0074] In alternative embodiments, the first and third adhered portions 111 , 121 may be adhered to each other, and / or the second and fourth adhered portions 112 , 122 may be adhered to each other.

[0075] 1-6, the adhesive patch 400 is positioned on the top seal 170 midway between the first and second side walls 106, 107 of the bag 100. In other words, it adheres to the top seal 170. Figure 2 For clarity, the fifth adhesive portion 130 is shown on Figure 2 4 is shown without adhesive patch 400 adhered thereto. The fifth portion 130 may form a weak link to the top seal 170, which will be referred to below. Fig. 9 As further described, the adhesive patch 400 placed thereon may thus be used to ensure that the package 1 is properly sealed.

[0076] The adhesive layer of adhesive patch 400 may be a self-adhesive layer, for example a self-adhesive layer configured to allow resealing of bag 100 by adhesive patch 400. A self-adhesive layer is an adhesive layer that adheres without being wetted. Fig.14 A package 1 is shown in an open, folded and resealed state, such as the package 1 shown in FIGS. 1-6 , wherein an adhesive patch 400 is used to reseal the package 1. The adhesive patch 400 herein includes a non-adhesive gripping portion 410 configured to be gripped by a user for releasing at least a second portion 404 of the adhesive patch 400 from the bag 100. The gripping portion 410 is located adjacent to the second portion 404 of the adhesive patch 400.

[0077] Adhesive patch 400 includes a backing material with an adhesive layer disposed thereon. The backing material can be any type of backing material known in the art. For example, paper material, polyester film, polypropylene film, paper backing or other materials can be used as the backing material.

[0078] exist Fig.14 In the illustrated embodiment, the user has removed all items 300 of the top stack 201 and rolled down the bag 100 before resealing the bag 100 using the adhesive patch 400. In conjunction with the rolling up of the bag 100, the entire adhesive patch 400 has been removed from the bag 100 and subsequently reattached, with the first portion 403 adhered to a portion of the bag 100 that constitutes the front wall 104 in the sealed state, and the second portion 404 adhered to the back wall 105. In this context, the same adhesive can be used for the adhesive layers in the first and second portions 403, 404 of the adhesive patch 400, thereby allowing the entire adhesive patch 400 to be released and resealed.

[0079] In an alternative embodiment, the first portion 403 may use a different adhesive than the second portion 404. The first portion 403 may include an adhesive that securely attaches the adhesive patch 400 to the top seal 170 of the bag 100. The second portion 404 may include an adhesive that forms a releasable bond with another surface of the bag 100. In such an embodiment, resealing of the opened bag 100 may be achieved by folding down the upper portion of the bag 100 (including the ruptured top seal 170) and attaching the second portion 404 of the adhesive patch 400 to, for example, the front wall 104 or the back wall 105. The first portion 403 of the adhesive patch 400 remains securely attached to the ruptured top seal 170 during resealing.

[0080] Fig.11A second embodiment of packaging 1 is shown, which differs only from the first embodiment shown in Figures 1-6 in that a first adhesive patch 400 and a second adhesive patch 400' are provided instead of a single adhesive patch. Patches 400, 400' are configured together to hold the top seal 170 folded onto one of the first and second top surfaces 171, 172 to the second top surface 172. The two adhesive patches 400, 400' are identical in this article, but they may have different shapes or otherwise differ in other embodiments. The first adhesive patch 400 has a first portion 403, which is attached to the first outer surface 170a of the top seal 170 between the fifth adhesive portion 130 and the first side wall 106, i.e., attached to the second adhesive portion 112. The second adhesive patch 400' has a first portion 403', which is attached to the first outer surface 170a of the top seal 170 between the fifth adhesive portion 130 and the second side wall 107, i.e., attached to the first adhesive portion 111. The second portions 404, 404' of both adhesive patches 400, 400' are adhered to the second top surface 172 and the rear wall 105 connected thereto.

[0081] Fig.12 A third embodiment of the package 1 is shown, which differs from the second embodiment only in how the first adhesive patch 400 and the second adhesive patch 400' are adhered to the bag 100. In the third embodiment, the first portion 403 of the first adhesive patch 400 is adhered to the first outer surface 170a of the top seal 170 on the one hand, and the second portion 404 is adhered to the first side wall 106. The first portion 403' of the second adhesive patch 400' is adhered to the first outer surface 170a of the top seal 170, and the second portion 404' is adhered to the second side wall 107. In this embodiment, the adhesive patches 400, 400' are not adhered to any of the front and rear walls 104, 105.

[0082] Fig.13 A fourth embodiment of the package 1 is shown, which differs from the third embodiment only in that, instead of two adhesive patches 400, 400' adhered to opposite side walls 106, 107, a single adhesive patch 400 is provided extending from the first side wall 106 all the way to the second side wall 107. The adhesive patch 400 has a first portion 403 adhered to the first outer surface 170a of the top seal 170, a second portion 404 adhered to the first side wall 106 and a third portion 405 adhered to the second side wall 107. It thus has an elongated shape and can be referred to as an adhesive strip.

[0083] exist Figure 11-13In any of the embodiments shown, each adhesive patch 400, 400' may of course be provided with at least one non-adhesive gripping portion, as shown in reference Fig.14 described.

[0084] In the illustrated embodiment, when the adhesive patch 400 or the plurality of adhesive patches 400, 400' retains the top seal 170 folded onto one of the first top surface 171 and the second top surface 172, the sealed top 102 of the package 1 forms a flat or substantially flat surface extending parallel to the sealed bottom 101. Thus, when in a position such as Figure 1b In the sealed and folded state shown, the package 1 has the basic shape of a cuboid (rectangular block).

[0085] The bag 100 includes an adhesive layer 150 disposed on the inner surface portions 113, 114, 115, 116, 117, 118, 123, 124, 125, 126 of the peripheral wall 103. Fig. 9 1, wherein the adhesive layer 150 is shown as a shaded area. The adhesive layer 150 is disposed on the second side of the sheet 110, forming the interior of the bag 110. The adhesive layer 150 is used to adhere the inner surface portions to each other to form a butt seam as described above. The adhesive layer may have a thickness of 28-45 g / m 2 , preferably 30-40g / m 2 , or more preferably 34-38g / m 2 The basis weight is , and it is a hot melt adhesive layer.

[0086] The basis weight of the adhesive layer 150 can be determined by weighing a first sample of the sheet 110 on which the adhesive layer 150 is disposed and a second sample of the same size on which the adhesive layer is not disposed. Alternatively, the adhesive layer can be removed from the first sample and then weighed again. The total weight of the adhesive layer disposed on the first sample is thus obtained as the weight difference between the sample with and without the adhesive layer. The weight of the adhesive layer is divided by the surface area of ​​the first sample to obtain the basis weight.

[0087] Adhesive layer 150 may, for example, include or be composed of a hot melt adhesive. However, the adhesive is not limited to a hot melt adhesive, and it may be any type of adhesive suitable for the application. Other types of adhesives may be adhesives that are soluble in water. Such adhesives include starch-based adhesives, polyvinyl alcohol-based adhesives, and polyethylene oxide-based adhesives. If the adhesive is not water-soluble, a water-dispersible adhesive may be used similarly. Suitable examples of water-dispersible adhesives include thermoplastic elastomer-based adhesives and polyvinyl acetate-based adhesives. Any suitable pressure-sensitive adhesive may also be used.

[0088] The adhesive layer 150 is partially disposed here on the excess top portion 109 cut off after sealing. The adhesive layer 150 may have a width W of 30-60 mm measured in the height direction of the bag 100 before adhesion, folding and cutting. ad .

[0089] The top seal 170 at the top 102 of the bag 100 can be achieved by pressing two sealing strips against each other, wherein the folded top portion 113, 114, 115, 116, 117, 118, 123, 124, 125, 126 of the bag 100 includes an adhesive layer 150 interposed between the sealing strips. Thus, the hot melt adhesive applied to the inside of the bag 100 melts, and the folded top portions 113, 114, 115, 116, 117, 118, 123, 124, 125, 126 are attached to each other and form the top seal 170. The seal width achieved by the sealing strips can be 3-10 mm, more preferably 3-6 mm, measured in the height direction of the bag 100. After cutting the bag 100, the seal width can be smaller or the same, depending on whether the cutting line 108 along which the cutting is performed is above the seal.

[0090] The seal of the package may have a tensile strength of at least 1N / 25.4mm. For example, each of the multiple seals of the package of the present disclosure may have a tensile strength between 1N / 25.4mm and about 22N / 25.4mm, more preferably from about 3N / 25.4mm to about 17N / 25.4mm. The tensile strength of the seal mentioned herein can be determined by the tensile test method described in ASTM F88-21 as modified herein.

[0091] As described above, the fifth portion 130 may form a weak link of the top seal 170. This may be due to the uneven thickness of the top seal 170 when the inner surface portions of the peripheral wall are sealed to each other after the bag 100 is filled with the absorbent article 300. As described, the top seal 170 may be implemented by pressing two sealing strips against each other, wherein the folded top portions 113, 114, 115, 116, 117, 118, 123, 124, 125, 126 of the bag 100 include an adhesive layer 150 interposed between the sealing strips. As a result, the hot melt adhesive applied to the interior of the bag 100 melts, and the folded top portions 113, 114, 115, 116, 117, 118, 123, 124, 125, 126 are attached to each other and form the top seal 170. Due to the uneven thickness, since the fifth part 130 includes only two layers of material compared to four layers of material at the first and third adhesion portions 111, 121 and the second and fourth adhesion portions 112, 122, it may be the case that insufficient heat and / or pressure is applied in the area of ​​the fifth part 130, resulting in the two layers forming the fifth part 130 not being properly adhered together.

[0092] As used herein, paper material is understood to be a material produced by pressing moist fibers together, dehydrating and drying the fibers into a preferably flexible sheet. The paper material used herein may have a viscosity of 50 to 90 g / m2 as measured according to ISO 536 standard. 2 The ratio between the basis weight of the paper material used for the bag 100 and the basis weight of the adhesive layer 150 may be in the range of 1.6-25, preferably in the range of 1.8-22. For example, the paper material may have a basis weight of 70 g / m 2 The basis weight of the adhesive layer 150 (such as a hot melt adhesive layer) may have a basis weight of about 36 g / m 2 The basis weight.

[0093] The first paper material may have any one or more of the following properties:

[0094] - a tensile strength of 4 to 10 kN / m, preferably 6 to 8 kN / m, measured in the machine direction according to ISO 1924-3 standard, and a tensile strength of 2 to 6 kN / m, preferably 3 to 5 kN / m, measured in the transverse direction;

[0095] - Tear index in machine direction according to ISO 1974 standard 8 to 14 mNm 2 / g, and the tear index measured in the transverse direction is 8 to 15 mNm 2 / g;

[0096] - a tear strength of 400 to 1300 mN measured in the machine direction and 450 to 1400 mN measured in the transverse direction according to ISO 1974 standard,

[0097] - The stretch measured in the machine direction according to ISO 1924-3 standard is between 1% and 6%, and the stretch measured in the transverse direction is between 5% and 12%.

[0098] The second paper material may be of the same nature or of different nature.

[0099] like Figure 2 As shown, in some embodiments, the bag 100 may include a first notch 160 for tearing the bag 100. The first notch 160 is formed at the top edge of the second adhesive portion 112 herein, but it may alternatively be provided in any one of the first, third, and fourth adhesive portions 111, 121, 122. As further shown, the bag 100 may alternatively or additionally include a second notch 160' for tearing the bag 100, the second notch 160' being formed below only one of the adhesive portions, herein below the first adhesive portion 111. In alternative embodiments, the notches 160, 160' may be formed by Figure 3 The first weakening line 161 in the form of a perforated line or a scored line as shown may be substituted or supplemented. The first weakening line may be located, for example, below the top seal 170, such as Figure 3 In other embodiments, no notch or first weakened line is provided. In those cases, the bag 100 can be opened, for example, by manually pulling the opposite adhesive portion. The package 1 in the opened state is Figure 4 Shown in.

[0100] The package 1 may also include one or more second weakening lines 162, 163 configured for use in conjunction with the removal of a portion of the bag 100. In the first embodiment shown in FIGS. 1-6, an upper second weakening line 162 and a lower second weakening line 163 are provided, both extending around the peripheral wall 103. The upper second weakening line 162 extends at a level such that when a user tears the bag along the upper second weakening line 162, the items 300 in the top stack 201 are exposed and easily accessible to the user. The lower second weakening line 163 extends at a level such that when the bag 100 is torn along the lower second weakening line 163, the items 300 in the bottom stack 202 are exposed and easily accessible to the user.

[0101] Rectangular sheet 110 in Fig. 91 and 2. As previously described, the rectangular sheet 110 is shown from its first side, which forms the outer wall of the bag 100 after folding and sealing. In order to form the peripheral side wall 103, the edge portion 105a of the back wall 105 overlaps with the rectangular seam portion 127 located adjacent to the second side wall 107 on the rectangular sheet 110. After folding the sheet 110, the edge portion 105a of the back wall 105 overlaps with the seam portion 127 and forms an overlapping seam 140. Therefore, the seam portion 127 is hidden behind the edge portion 105a and forms a part of the back wall 105 after folding and sealing. Figure 6 As shown, the overlapping seam 140 extends from the bottom 101 of the bag 100 to the top 102 of the bag 100. An adhesive (not shown) can be used to form the overlapping seam 140. The adhesive for forming the overlapping seam 140 can be arranged as a layer on the inner side of the edge portion 105a, but preferably, the adhesive is arranged as a layer on the seam portion 127, that is, on the first side of the rectangular sheet 110 facing outward after folding and sealing. Therefore, the adhesive layer for forming the overlapping seam 140 and the adhesive layer 150 are arranged on the opposite side of the sheet 110. The adhesive for forming the overlapping seam 140 can be the same type as the type used for the adhesive layer 150, or a different type. The adhesive can be, for example, a hot melt adhesive, that is, not a water-soluble thermoplastic adhesive. However, the adhesive is not limited to a hot melt adhesive, it can be any type of adhesive suitable for application. Other types of suitable adhesives can be adhesives that can be dissolved in water. Such adhesives include starch-based adhesives, polyvinyl alcohol-based adhesives and polyethylene oxide-based adhesives. If the adhesive is not water soluble, a water dispersible adhesive may similarly be used. Suitable examples of water dispersible adhesives include thermoplastic elastomer-based adhesives and polyvinyl acetate-based adhesives. Any suitable pressure sensitive adhesive may also be used.

[0102] Fig. 9 The seam portion 127 shown includes an end 151 of an adhesive layer 150 disposed on an inner surface portion 115b, which forms a portion of a first top portion 115 of a second top surface 172 after the overlapping seam 140 has been formed. The inner surface portion 115b forms the first top portion 115 of the second top surface 172 together with the adjacent inner surface portion 115a. After the overlapping seam 140 has been formed, the inner surface portion 115b is located inside the edge portion 172a of the second top surface 172, i.e., on the inside of the package 1. The adhesive layer 150 does not extend onto the edge portion 172a of the second top surface 172. The edge portion 105a of the rear wall 105 and the edge portion 172a of the second top surface 172 can have a width of about 25mm in this article.

[0103] Fig. 9The adhesive layer 150 is shown as a continuous adhesive layer. Fig.10 An alternative is shown in , in which the adhesive layer 150' is a non-continuous adhesive layer, which includes a first layer portion 150a disposed on the second top surface 172, a second layer portion 150b disposed on the first side wall 106, a third layer portion 150c disposed on the first top surface 171, a fourth layer portion 150d disposed on the second side wall 107, and an end layer portion 151 disposed on the seam portion 127. Between every two adjacent layer portions 150a-d, 151, an adhesive-free area is provided. The dotted fold line is located in the adhesive-free area. The distance D between every two adjacent layer portions 150a-d, 151 can be in the range of 5-15mm, preferably 8.5-11.5mm, such as about 10mm. This prevents the corners from becoming adhered during the manufacture of the bag 100 before the bag 100 is filled with the absorbent pad 300. In Fig.10 In the illustrated embodiment, the non-continuous adhesive layer 150' does not extend onto the edge portion 105a of the rear wall 105, nor onto the edge portion 127a of the seam portion 127. The adhesive-free edge portion 127a of the seam portion 127 may have a width of about 5 mm in this context. The overlapping seam 140 may be formed in the same manner as described above with reference to Fig. 9 1, for example by providing an adhesive layer on the seam portion 127, ie, on the first side of the rectangular sheet 110 that faces outward after folding and sealing. Fig. 9 , Fig.10 The sheet 110 is shown from a first side thereof, forming the outer wall of the bag 100 after folding and sealing.

[0104] The bag 100 may also include a vent (not shown) located at or near the bottom 101 of the bag 100 for allowing air to escape from the bag 100, for example when the pad 300 is loaded into the bag 100, and for reducing tension that may be generated when the bag 100 is subjected to pressure. The vent may be located near the edge between any two adjacent walls. It may preferably be located at one of the side walls 106, 107 adjacent to the bottom 101. It may alternatively be formed as a non-sealed lower portion of the overlapping seam 140.

[0105] The example configuration of bottom 101 is Figure 5 . The sealed bottom 101 of the bag 100 is a block bottom, formed herein by folding a rectangular lower portion 119 of the sheet 110 and adhering the resulting folded portions to each other to form a flat and rectangular bottom 101. The sealed bottom 101 is formed using overlapping seams to provide a flat bottom. A rectangular patch 180 forming a bottom label is glued to the bottom 101 as a cover.

[0106] All outsides of the bag 100 may be covered with a layer of varnish, thereby protecting any printed parts of the bag 100. The printed parts may be provided on the peripheral wall 103 as well as on the top 102 and / or on the bottom label.

[0107] Since the absorbent pad 300 is not compressed or only slightly compressed, the package 1 has relatively sharp 90° edges. The front and rear walls 104, 105 and the first and second side walls 106, 107 are relatively flat. Therefore, the length L of the package 1 is tot and the width W is nearly constant along the height H of the package, as can be seen in Figure 1. The maximum total length L of the package 1 measured anywhere along the stack height H is tot Preferably with a minimum overall length L measured at the bottom 101 of the seal or the top 102 of the seal tot The difference is 10 mm or less, more preferably 8 mm or less. In other words, the side walls 106, 107 do not protrude significantly.

[0108] In other examples of package 1, absorbent articles 300 may be diapers, such as diapers arranged in one or two stacks within bag 100. Diapers are typically significantly compressed within bag 100, and this may cause bulging of side walls 106, 107. In those cases, the maximum overall length L of package 1 is tot The minimum total length L that can be measured at the bottom 101 of the seal or the top 102 of the seal tot The difference is 10mm or more.

[0109] Two stacks 201 , 202 of folded and individually wrapped absorbent pads 300 , such as disposable personal hygiene absorbent pads in the form of incontinence guards, sanitary napkins, pantiliners or the like, are arranged in the bag 100 in most of the illustrated embodiments.

[0110] exist Fig.15 In the fifth embodiment shown, the package 1 comprises a single stack 200 of folded and individually wrapped absorbent pads 300. Figure 1a Compared to the package 1 shown in FIG. 1 , the single stack 200 herein comprises a greater number of folded and optionally individually wrapped pads 300. Thus, the package 1 according to the fifth embodiment has a smaller height H and a greater length L than the package 1 according to the first embodiment. tot In particular, the fifth adhesive portion 130 is longer than in the first embodiment. The bag 100 includes two adhesive patches 400, 400' for pressing against the top seal 170. Fig.15In the embodiment of the present invention, the package 1 stands upright on the closed bottom 101. However, the package 1 can be arranged so that it stands on its first side wall or second side wall 106, 107, for example, in a store or on a shelf. Then, the top seal 170 will be arranged vertically rather than horizontally on the shelf. Alternatively, the package 1 can be arranged so that it is located on the closed top 102 including the top seal 170.

[0111] Figure 7-8 An absorbent pad 300 in the form of an incontinence guard according to an exemplary embodiment is shown. Such an incontinence guard is described, for example, in WO2017086849. The absorbent pad 300 may comprise, purely by way of example, a liquid permeable top sheet 309 bonded to an underlying acquisition or distribution layer (not shown), a liquid impermeable back sheet (not shown), and an absorbent core (not shown) sandwiched between the acquisition or distribution layer and the liquid impermeable back sheet. However, many different configurations are possible.

[0112] The absorbent pad 300 shown is a wingless incontinence guard which is intended to be adhesively attached to the user's underwear, for example by means of an adhesive provided on the outer side of the backsheet, for fastening the absorbent pad 300 to the underwear. However, the present disclosure is equally applicable to wing-type absorbent pads, in which transversely protruding wings are intended to be folded around the edges of the user's underwear to fasten the absorbent pad 300 to the underwear.

[0113] Liquid-permeable top sheet 309 can comprise nonwoven material, for example spunbond, meltblown, combing, spunlace, wet-laid etc., which can be made of natural fibers such as wood pulp or cotton fibers, synthetic fibers such as polyester, polyethylene, polypropylene, viscose etc. or by their mixture. Top sheet 309 materials can also be made of tow fibers, porous foam, open-cell plastic films etc. The material suitable as top sheet material should be soft and non-irritating to the skin, and easily penetrated by body fluids (such as urine or menstrual fluid), and demonstrate low rewetting characteristics. Top sheet 309 can comprise weldable fibers, so that it can be bonded to the following sheet material by welding (such as ultrasonic welding). Alternatively, top sheet 309 can be bonded to the following material with adhesive, or only be placed on the top of the following material.

[0114] If an acquisition or distribution layer is used in the absorbent pad 300, such an acquisition or distribution layer may include a material suitable for bonding to the top sheet 309. For example, if welding techniques are used to bond the top sheet 309 to the acquisition or distribution layer, the material of the acquisition or distribution layer should include at least partially weldable fibers. For example, the weldable fibers may be polyethylene fibers coated with a polypropylene layer. The acquisition or distribution layer may also include pure polyethylene fibers. In one specific example, less than 30% of the fibers in the acquisition or distribution layer are polyethylene fibers, and more than 70% of the fibers are welded fibers consisting of polyethylene fibers coated with polypropylene.

[0115] The absorbent core may include any conventional material suitable for absorbing discharged body exudates, such as cellulosic fluff pulp, tissue paper layers, high absorbent polymers (superabsorbents), absorbent foam materials including hydrogel foam materials, absorbent nonwoven materials, etc. Similar to the above, if welding techniques are used to directly bond the top sheet 309 to the absorbent core, the material of the absorbent core should include at least partially weldable fibers.

[0116] The liquid-impermeable backsheet may comprise a thin plastic film, such as a polyethylene or polypropylene film, a nonwoven coated with a liquid-impermeable material, a hydrophobic nonwoven resistant to liquid penetration, or a laminate of a plastic film and a nonwoven. The backsheet material may be breathable so as to allow vapor to escape from the absorbent core while still preventing liquid from passing through the backsheet material.

[0117] In one embodiment, the absorbent pad 300 may be an absorbent pad commercially sold by Essity Hygiene and Health AB under the name TENAdiscreet Mini.The package 1 may then comprise two stacks 201 , 202 with 8 or 10 absorbent pads 300 in each stack 201 , 202 purely by way of example.

[0118] In another embodiment, the absorbent pad 300 may be an absorbent pad commercially sold by Essity Hygiene and Health AB under the name TENAdiscreet Mini Plus.

[0119] The package 1 may then comprise two stacks 201 , 202 with 8 or 10 absorbent pads 300 in each stack 201 , 202 purely by way of example.

[0120] In the illustrated embodiment, each absorbent pad 300 is disposed in a separate bag 301, such as a thin sheet or the like, to which the absorbent pad 300 is releasably adhered before use. The sheet material used to form the bag 301 can be a single-layer sheet of any suitable material known to those skilled in the art, such as a polyethylene or polypropylene film or a nonwoven material or paper. The bag 301 can also be a laminate comprising at least two different layers. Laminates suitable for packaging sanitary articles are considered to be known to those skilled in the art and are not intended to limit the present disclosure in any way.

[0121] The absorbent pad 300 attached to a single packing set 301 is folded twice herein to form three folded layers, wherein the front portion 303 overlaps the rear portion 304, and both the front and rear portions 303, 304 overlap the center portion 305. Figure 8In the illustrated embodiment, the liner 300 is folded together with the bag 301. Alternatively, the pad may be pre-folded and inserted into the bag. Each individually wrapped absorbent pad 300 includes two sealed bag portions 302 extending perpendicular to opposite folded edges 306, 307 of the absorbent pad 300, see Figure 7 One of the sealed package parts 302 faces upward within the bag 100, as shown in FIGS. 1 and 2. Figure 4 Thus, the user can easily remove the wrapped absorbent pad 300 from the opened top of the bag 100 by grasping the sealed wrapping portion 302. However, the sealed wrapping portion 302 is not limited to being arranged to face upward in the bag 100. Alternatively, it can face any other surface of the bag 100.

[0122] The sealed package portion 302 can be sealed by an adhesive (e.g., a resealable adhesive or a non-resealable adhesive) and / or sealed by ultrasonic welding or heat welding. The term "resealable adhesive" refers to an adhesive that provides a non-permanent adhesive bond between two adhered surfaces, i.e., a bond that can be broken by applying a tensile force to the adherend and regenerated by applying pressure to the adherend. The resealable adhesive can be a pressure-sensitive hot melt adhesive.

[0123] The stacking direction SD of each stack 201, 202 within the bag 100 is perpendicular to the first and second side walls 106, 107 of the bag 100, see FIG1. ​​Thus, within each stack 201, 202, the folded and individually wrapped absorbent pads 300 are stacked with their side surfaces 310 facing each other. The side surfaces 310 are aligned with the first and second side walls 106, 107 of the bag 100. Another alternative way to stack the articles 300 in the bag 100 is to arrange them with their side surfaces 310 parallel to the bottom 101. The package 1 can then comprise one or two stacks 300 of absorbent articles adjacent to each other.

[0124] To manufacture a package 1 according to the present disclosure, at least one stack 201, 202 of absorbent articles 300 is arranged as described above in a bag 100, wherein the bag has a closed bottom 101, an open top 102 and a peripheral wall 103 between the bottom 101 and the top 102. The inner surface top portions of the peripheral wall 103 provided with the adhesive layer 150 are thereafter adhered to each other as described above to obtain a closed top 102.

[0125] It should be understood that the above description is only exemplary in nature and is not intended to limit the present disclosure, its application or use. Although specific examples have been described in the specification and shown in the drawings, it will be understood by those of ordinary skill in the art that various changes can be made and equivalents can be used to replace its elements without departing from the scope of the present disclosure defined in the claims, and the mixing and matching of features, elements and / or functions between various examples is explicitly contemplated herein, so that those of ordinary skill in the art will understand from the present disclosure that, unless otherwise described above, the features, elements and / or functions of an example can be appropriately incorporated into another example.
