DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[0064] Various aspects of the disclosure will hereinafter be described in conjunction with the appended drawings to illustrate and not to limit the disclosure, wherein like designations denote like elements, and variations of the described aspects are not restricted to the specifically shown embodiments but are applicable on other variations of the disclosure.
[0065] A package 1 according to embodiments of the disclosure is schematically illustrated in
[0066] The package 1 further comprises at least one adhesive patch 400 configured to hold the top seal 170 folded onto one of the first and the second top surfaces 171, 172. In the embodiment illustrated in
[0067] The bag 100 is formed from a single sheet 110 of rectangular paper as illustrated in
[0068] The top seal 170 has been formed by folding and adhering inner surface top portions of the paper sheet 110 to one another so as to form wings, or fins.
[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 L.sub.1 as shown in
[0070] In the illustrated embodiments, the first length L.sub.1, the second length L.sub.2, the third length L.sub.3, and the fourth length L.sub.4 are all equal, within manufacturing tolerances. The fifth length L.sub.5 is herein less than less than 75% of each one of the first length L.sub.1, the second length L.sub.2, the third length L.sub.3, and the fourth length L.sub.4, preferably less than 65%, or less than 60%. The first length L.sub.1, the second length L.sub.2, the third length L.sub.3, and the fourth length L.sub.4 may be between 30-50 mm, preferably 35-45 mm. The fifth length L.sub.5 may be 1-30 mm, more preferably 3-25 mm. A total length L.sub.tot of the front wall 104 and/or back wall 105 of the bag 100, as measured between the side walls 106, 107 at a bottom of the package 1, is essentially equal to the sum of the first length L.sub.1, the second length L.sub.2, and the fifth length L.sub.5 and/or the sum of the third length L.sub.3, the fourth length L.sub.4 and the fifth length L.sub.5.
[0071] In the illustrated embodiment, the first length L.sub.1 is 39 mm and the fifth length L.sub.5 is 22 mm, i.e., 56% of the first length L.sub.1. In the illustrated embodiment the bag 100 has a total length L.sub.tot of 100 mm as measured between the side walls 106, 107, and a total width W as measured between the front and rear walls 104, 105 of 78 mm. A filling height H of the bag 100 is in the illustrated embodiment 163 mm.
[0072] In another embodiment, the first length L.sub.1 is 45 mm and the fifth length L.sub.5 is 10 mm, i.e., 22% of first length L.sub.1. The bag 100 has a total length L.sub.tot of 100 mm as measured between the side walls 106, 107, and a total width W as measured between the front and rear walls 104, 105 of 88 mm. A filling height H of the bag 100 is in the illustrated embodiment 165 mm.
[0073] As best seen in
[0074] In alternative embodiments, the first and third adhered portions 111, 121 may be adhered to one another, and/or the second and fourth adhered portions 112, 122 may be adhered to one another.
[0075] In the illustrated embodiments of
[0076] The fifth portion 130 may form a weak link of the top seal 170, which will be further described below with reference to
[0077] The adhesive layer of the adhesive patch 400 may be a self-adhesive layer, such as a self-adhesive layer configured to allow resealing of the bag 100 by the adhesive patch 400. A self-adhesive layer is an adhesive layer which sticks without wetting.
[0078] The adhesive patch 400 comprises a backing material on which the adhesive layer is provided. The backing material may be any type of tape backing materials well known in the art. For example, paper materials, polyester films, polypropylene films, paper backings, or other materials may be used as the backing material.
[0079] In the embodiment illustrated in
[0080] In alternative embodiments, a different adhesive may be used for the first portion 403 than for the second portion 404. The first portion 403 may comprise an adhesive that securely attaches the adhesive patch 400 to the top seal 170 of the bag 100. The second portion 404 may comprise an adhesive that forms a releasable bond with another surface of the bag 100. In such embodiments, resealing of the opened bag 100 may be achieved by folding down an upper part of the bag 100, including the broken top seal 170, and attaching the second portion 404 of the adhesive patch 400 to, e.g., the front wall 104 or the rear wall 105. The first portion 403 of the adhesive patch 400 remains securely attached to the broken top seal 170 during the resealing.
[0081]
[0082]
[0083]
[0084] In any one of the embodiments illustrated in
[0085] In the illustrated embodiments, the sealed top 102 of the package 1 forms a planar or an essentially planar surface extending in parallel with the sealed bottom 101 when the adhesive patch 400 or patches 400, 400 hold/s the top seal 170 folded onto one of the first and the second top surfaces 171, 172. Hence, the package 1, when in the sealed and folded state shown in e.g.
[0086] The bag 100 comprises an adhesion layer 150 provided on the inner surface portions 113, 114, 115, 116, 117, 118, 123, 124, 125, 126 of the peripheral wall 103, as shown in
[0087] The basis weight of the adhesion layer 150 may be determined by weighing a first sample of the sheet 110 on which the adhesion layer 150 is provided, and a second sample of the same size on which no adhesion layer is provided. Alternatively, the adhesion layer may be removed from the first sample, whereafter the first sample is weighed again. A total weight of the adhesion layer provided on the first sample is thereby obtained as the difference in weight between the samples with and without adhesion layer. The weight of the adhesion layer is divided by a surface area of the first sample to obtain the basis weight.
[0088] The adhesion layer 150 can, for example, comprise or consist of a hot melt adhesive. However, the adhesive is not limited to a hot melt adhesive, it may be any kind of adhesive suitable for the application. Other kind of adhesives can be adhesives which can dissolve in water. Such adhesives include starch based adhesives, polyvinyl alcohol based adhesives, and polyethylene oxide based adhesives. If the adhesive is not water-soluble, then water-dispersible adhesives may similarly be utilized. Suitable examples of water dispersible adhesives include thermoplastic elastomer based adhesives and polyvinyl acetate based adhesives. Any suitable pressure sensitive adhesives may also be used.
[0089] The adhesion layer 150 is herein partially provided on the superfluous top portion 109 which is cut away after sealing. The adhesion layer 150 may prior to adhesion, folding and cutting have a width W.sub.ad of 30-60 mm as measured in a height direction of the bag 100.
[0090] The top seal 170 at the top 102 of the bag 100 can be accomplished by pressing two seal bars against each other, with the folded top portions 113, 114, 115, 116, 117, 118, 123, 124, 125, 126 of the bag 100 comprising the adhesion layer 150 inserted between the seal bars. Thereby, 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 attach to each other and form the top seal 170. The sealing width accomplished by the sealing bars may be 3-10 mm measured in a height direction of the bag 100, more preferably 3-6 mm. After the bag 100 has been cut, the sealing width may be smaller or the same, depending on if the cutting line 108 along which the cut is made is above the seal or not.
[0091] The seal of the packages may have a tensile strength of at least 1 N per 25.4 mm. For example, each of the plurality of seals of the packages of the present disclosure may have a tensile strength of between 1 N per 25.4 mm to about 22 N per 25.4 mm, more preferably from about 3 N per 25.4 mm to about 17 N per 25.4 mm. The tensile strengths of the seals mentioned herein can be determined by the tensile test method described in ASTM F88-21 as modified herein.
[0092] As mentioned above, the fifth portion 130 may form a weak link of the top seal 170. This can be due to the uneven thickness of the top seal 170 when the inner surface portions of the peripheral wall are sealed to one another after filling the bag 100 with the absorbent articles 300. As described, the top seal 170 can be accomplished by pressing two seal bars against each other, with the folded top portions 113, 114, 115, 116, 117, 118, 123, 124, 125, 126 of the bag 100 comprising the adhesion layer 150 inserted between the seal bars. Thereby, 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 attach to each other and form the top seal 170. Due to an uneven thickness, arising since the fifth portion 130 only comprises two layers of material compared to four layers of material at the first and third adhered portions 111, 121 and at the second and fourth adhered portions 112, 122, it might be the case that the heat and/or pressure applied in the area of the fifth portion 130 is/are insufficient, causing the two layers forming the fifth portion 130 to not stick together properly.
[0093] As used herein, a paper material is to be understood as a material produced by pressing together moist fibres, dewatering, and drying the fibres into preferably flexible sheets. The paper material used herein may have a basis weight between 50 and 90 g/m.sup.2 as measured according to the ISO 536 standard. A ratio between the basis weight of the paper material used for the bag 100 and the basis weight of the adhesion layer 150 may be within a range of 1.6-2.5, preferably 1.8-2.2. For example, the paper material may have a basis weight of 70 g/m.sup.2 and the adhesion layer 150, such as the hot-melt adhesion layer, may have a basis weight of approximately 36 g/m.sup.2.
[0094] The first paper material may have any one or more of following properties: [0095] a tensile strength measured according to the ISO 1924-3 standard in a machine direction between 4 and 10 kN/m, preferably between 6 and 8 kN/m, and in a cross direction between 2 and 6 kN/m, preferably between 3 and 5 kN/m; [0096] a tear index measured according to the ISO 1974 standard in a machine direction between 8 and 14 mNm.sup.2/g, and in a cross direction between 8 and 15 mNm.sup.2/g; [0097] a tear strength measured according to the ISO 1974 standard in a machine direction between 400 and 1300 mN, and in a cross direction between 450 and 1400 mN, [0098] a stretch measured according to the ISO 1924-3 standard in a machine direction between 1 and 6 %, and in a cross direction between 5 and 12 %.
[0099] The second paper material may have the same properties or differ.
[0100] As illustrated in
[0101] The package 1 may further comprise one or more second weakening lines 162, 163 configured for removing a portion of the bag 100 in connection with usage. In the first embodiment illustrated in
[0102] The rectangular sheet 110 is in
[0103] The seam portion 127 illustrated in
[0104] The adhesion layer 150 shown in
[0105] The bag 100 may further comprise an air displacement hole (not shown) located at or close to the bottom 101 of the bag 100 for allowing air to escape from the bag 100, such as when loading the pads 300 into the bag 100 and for reducing tension that may arise as the bag 100 is subjected to pressure. The air displacement hole may be located close to an 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 overlap seam 140.
[0106] An example configuration of the bottom 101 is illustrated in
[0107] All external sides of the bag 100 may be covered with a layer of varnish, protecting any printed portions of the bag 100. Printed portions may be provided on the peripheral wall 103 as well as on the top 102 and/or on the bottom label.
[0108] Since the absorbent pads 300 are non-compressed or only slightly compressed, the package 1 has relatively sharp 90 edges. The front and rear walls 104, 105 as well as the first and second side walls 106, 107 are relatively flat. The length L.sub.tot of the package 1 as well as the width W are therefore close to constant along the height H of the package, as can be gleaned from
[0109] In other examples of the package 1, the absorbent articles 300 may be diapers, such as diapers arranged in one or two stacks within the bag 100. Diapers are often significantly compressed within the bag 100, and this may cause the side walls 106, 107 to bulge out. The maximum total length L.sub.tot of the package 1 may in those cases differ by 10 mm or more from the minimum total length L.sub.tot measured at the sealed bottom 101 or at the sealed top 102.
[0110] Two stacks 201, 202 of folded and individually wrapped absorbent pads 300, such as disposable personal hygiene absorbent pads in the form of incontinent shields, sanitary napkins, panty liners, or the like, are in most of the illustrated embodiments arranged in the bag 100.
[0111] In a fifth embodiment illustrated in
[0112]
[0113] The illustrated absorbent pad 300 is a wing-less incontinent shield that is intended to be adhesively attached to an underwear of a user, for example by means of adhesive that is provided on an outer side of the backsheet for fastening the absorbent pad 300 to said underwear. However, the disclosure is equally applicable to wing-type absorbent pads, where laterally protruding wings are intended to be folded around the edge of the underwear of a user for fastening the absorbent pad 300 to said underwear.
[0114] The liquid permeable topsheet 309 can comprise a nonwoven material, e.g. spunbonded, meltblown, carded, hydroentangled, wetlaid, etc. which can be composed of natural fibres, such as woodpulp or cotton fibres, synthetic fibres, such as polyester, polyethylene, polypropylene, viscose, etc. or from a mixture thereof. The topsheet 309 material may further be composed of tow fibres, porous foams, apertured plastic films etc. The materials suited as topsheet materials should be soft and non-irritating to the skin and be readily penetrated by body fluid, e g urine or menstrual fluid, and display low rewetting properties. The topsheet 309 may comprise weldable fibres for enabling bonding to the underlying sheet by means of welding, such as ultrasonic welding. Alternatively, the topsheet 309 may be bonded to the underlying material with adhesive, or just placed on top of the underlying material.
[0115] The acquisition or distribution layer, if such a layer is used in absorbent pad 300, may comprise a material suitable for bonding to the topsheet 309. For example, if welding technology is used for bonding the topsheet 309 to the acquisition or distribution layer, the material of the acquisition or distribution layer should include at least partly weldable fibres. For example, the weldable fibres may polyethylene fibres coated with a layer of polypropylene. The acquisition or distribution layer may further include pure polyethylene fibres. In a specific example less than 30% of the fibres in the acquisition or distribution layer are polyethylene fibres and more than 70% of the fibres are welding fibres consisting of polyethylene fibres coated with polypropylene.
[0116] The absorbent core may comprise any conventional material suitable for absorbing discharged bodily wastes, such as cellulosic fluff pulp, tissue layers, highly absorbent polymers (superabsorbents), absorbent foam materials including hydrogel-foam material, absorbent nonwoven materials or the like. Similar to above, if welding technology is used for bonding the topsheet 309 directly to the absorbent core, the material of the absorbent core should include at least partly weldable fibres.
[0117] The liquid impermeable backsheet may comprise a thin plastic film, e.g. a polyethylene or polypropylene film, a nonwoven material coated with a liquid impervious material, a hydrophobic nonwoven material which resists liquid penetration or laminates of plastic films and nonwoven materials. The backsheet material may be breathable so as to allow vapour to escape from the absorbent core, while still preventing liquids from passing through the backsheet material.
[0118] In one embodiment, the absorbent pad 300 may be an absorbent pad sold commercially by Essity Hygiene and Health AB under the name TENA discreet Mini. The package 1 may then comprise two stacks 201, 202 with, purely by way of example, 8 or 10 absorbent pads 300 in each stack 201, 202.
[0119] In another embodiment, the absorbent pad 300 may be an absorbent pad sold commercially by Essity Hygiene and Health AB under the name TENA discreet Mini Plus.
[0120] The package 1 may then comprise two stacks 201, 202 with, purely by way of example, 8 or 10 absorbent pads 300 in each stack 201, 202.
[0121] Each absorbent pad 300 is in the illustrated embodiment provided within an individual wrapper 301, such as a thin sheet or similar, to which the absorbent pad 300 is releasably adhered before use. The sheet material for forming the wrapper 301 may be a single ply sheet of any suitable material known to the person skilled in the art, such as polyethylene or polypropylene film or nonwoven or paper. The wrapper 301 may also be a laminate comprising at least two distinct layers. Laminates suitable for packaging of hygiene articles are assumed to be known to the person skilled in the art and are not in any way limiting for the present disclosure.
[0122] The absorbent pad 300 attached to the individual wrapper 301 is herein folded twice to form three folding layers, with a front portion 303 overlapping a rear portion 304, both the front and rear portions 303, 304 overlapping a centre portion 305. In the embodiment illustrated in
[0123] The sealed wrap portions 302 may be sealed by an adhesive, for example a resealable adhesive or a non-resealable adhesive and/or sealed by means of ultrasonic welding or heat welding. By the term resealable adhesive is meant an adhesive that provides a non-permanent adhesive bond between two adherent surfaces, i.e. a bond that may be broken by applying a pulling force to the adherent, and recreated by applying a pressing force to the adherent. The resealable adhesive may be a pressure-sensitive hotmelt adhesive.
[0124] A 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
[0125] To manufacture a package 1 according to the disclosure, the at least one stack 201, 202 of absorbent articles 300 is arranged in a bag 100 as described above, 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 adhesion layer 150 are thereafter adhered to one another as described above to obtain a closed top 102.
