Definitions

  • the present disclosure relates to packages and methods of making packages, and more particularly, to sealed reclosable packages and a method of making the same.
  • the field of disposable absorbent articles includes a wide variety of consumer products, including diapers, bibs, wipes, sanitary napkins, tampons, etc.
  • the absorbent articles are packaged in a flexible package, such as a package made of film.
  • Flexible packages for containing absorbent articles may include opposing first and second panels. Each panel may define a top edge portion, a bottom edge portion, a left side edge portion, and a right side edge portion. The first and second panels may be joined at a first seam along left side edge portions of the first and second panels and at a second seam along right side edge portions of the first and second panels.
  • the primary package may include a reclosable feature along a top or bottom edge portion of the package for opening and closing the packages.
  • the reclosable features may include a lid, tape tab fastener, hook and loop fastener, snap, button, or latch, for example.
  • adding reclosable features to the flexible package may add cost and complexity to the manufacturing of the package.
  • Some flexible packages include an integrated reclosable feature, such as a hood, in the second panel of the primary package.
  • the hood may be positioned proximate to the top or bottom edge portion of the primary package.
  • the hood may be configured in a closed configuration and an open configuration. In the closed configuration, the hood may cover the absorbent articles contained therein. In the open configuration, the hood may be folded away from the first panel to create an opening in the package that exposes the absorbent articles contained therein.
  • the first and second panels may be integrally connected in the portion of the panels opposite the hood. As such, the hood may provide the only access to the flexible package for inserting absorbent articles during the packaging process, and for removing the absorbent articles from the flexible package at the time of use by the consumer.
  • the package may not be sealed at the time of purchasing the flexible package of absorbent articles because of the opening created by the hood. Consequently, the absorbent articles may be subject to tampering or contamination before the package of absorbent articles is purchased by the consumer.
  • a flexible package provided with a hood is for example described in WO 2014/190102A1 .
  • DE 39 14 595 A1 discloses an example of a flexible package with a perforation.
  • the invention relates to a flexible reclosable package as defined by claim 1.
  • the hooded portion of the second panel may comprise a gusset, wherein the gusset forms a top panel of the package.
  • the flexible reclosable package may be integrally formed from a single piece of material.
  • the invention also relates to a method of forming a reclosable package, as defined by claim 13.
  • absorbent article refers to devices that absorb and contain body exudates, and, more specifically, refers to devices that are placed against or in proximity to the body of the wearer to absorb and contain the various exudates discharged from the body.
  • Absorbent articles may include diapers (baby diapers and diapers for adult incontinence), pants (for babies or for adults), absorbent inserts (which are intended to be inserted into an outer cover to form a diaper or pant), feminine care absorbent articles such as sanitary napkins or pantiliners, and the like.
  • exudates includes, but is not limited to, urine, blood, vaginal discharges, sweat and fecal matter.
  • Preferred absorbent articles of the present invention are disposable absorbent articles, more preferably disposable diapers and disposable pants.
  • disposable is used in its ordinary sense to mean an article that is disposed or discarded after a limited number of usage over varying lengths of time, for example, less than 20 usages, less than 10 usages, less than 5 usages, or less than 2 usages. If the disposable absorbent article is a diaper, a pant, sanitary napkin, sanitary pad or wet wipe for personal hygiene use, the disposable absorbent article is most often intended to be disposed after single use.
  • Disposable and compressible consumer products are products which are made of, or which comprise substantial amounts of compressible components, such as tissues, nonwovens, foams, wadding or the like. Such products are typically packaged and put on sale in a compressed form to reduce the amount of storage and shelf space. Disposable and compressible consumer products also encompass disposable absorbent articles.
  • diaper and “pant” refers to an absorbent article generally worn by babies, infants and incontinent persons about the lower torso so as to encircle the waist and legs of the wearer and that is specifically adapted to receive and contain urinary and fecal waste.
  • a pant as used herein, the longitudinal edges of the first and second waist region are attached to each other to a pre-form waist opening and leg openings. A pant is placed in position on the wearer by inserting the wearer's legs into the leg openings and sliding the pant absorbent article into position about the wearer's lower torso.
  • a pant may be pre-formed by any suitable technique including, but not limited to, joining together portions of the absorbent article using refastenable and/or non-refastenable bonds (e.g., seam, weld, adhesive, cohesive bond, fastener, etc.).
  • a pant may be preformed anywhere along the circumference of the article (e.g., side fastened, front waist fastened).
  • the waist opening and leg openings are only formed when the diaper is applied onto a wearer by (releasable) attaching the longitudinal edges of the first and second waist region to each other on both sides by a suitable fastening system.
  • a "pantiliner” and a “sanitary napkin” generally have two end regions and a middle region (i.e. a crotch region).
  • the pantiliner and the sanitary napkin have a body-facing surface and a garment facing surface.
  • the size and shape of the absorbent structure positioned between the topsheet and the backsheet can be altered to meet absorbent capacity requirements, and to provide comfort to the wearer.
  • the garment facing surface of the pantiliner and of the sanitary napkin can have thereon pressure sensitive adhesive for affixing to a wearer's undergarments. Typically, such adhesive is covered with a release strip which is removed before affixing to the undergarment.
  • Pantiliners can also be provided with lateral extensions known commonly in the art as “flaps” or “wings” intended to extend over and cover the panty elastics in the crotch region of the user's undergarment.
  • wings are normally not used with pantiliners but are more often used in sanitary napkins.
  • Sanitary napkins and pantiliners of the present invention comprise barrier leg cuffs.
  • Longitudinal means a direction running substantially perpendicular from a waist edge to a longitudinally opposing waist edge of an absorbent article when the article is in a flat out, uncontracted state, or from a waist edge to the bottom of the crotch, i.e. the fold line, in a bi-folded article.
  • “Lateral” refers to a direction running from a longitudinally extending side edge to a laterally opposing longitudinally extending side edge of an article and generally at a right angle to the longitudinal direction.
  • Machine direction (MD) is used herein to refer to the direction of material flow through a process.
  • relative placement and movement of material can be described as flowing in the machine direction through a process from upstream in the process to downstream in the process.
  • Cross direction (CD) is used herein to refer to a direction that is not parallel with, and usually perpendicular to, the machine direction.
  • “Sealed” refers herein to a package having an interior that is inaccessible until the package is ruptured.
  • a first line of weakness being provided “substantially” in fold refers herein to a line of weakness which may deviate slightly from the position of the fold due to manufacturing variations which may be inevitable in a high speed manufacturing process. Such deviations will be unsubstantial and unintended.
  • the present disclosure relates to flexible, reclosable packages for containing disposable compressible consumer products, such as absorbent articles, and further relates to flexible, sealed reclosable packages and methods of making the same.
  • the disposable compressible consumer products may be contained in the flexible, enclosable package in a compressed state.
  • Flexible, reclosable packages of the present disclosure include a first panel and an opposing second panel.
  • the first panel defines a first right side edge portion, a first left side edge portion, a first bottom edge portion, and a pleated portion.
  • the second panel defines a second right side edge portion, a second left side edge portion, a second bottom edge portion, and a hooded portion.
  • the first and second panels combine to define an interior and an exterior of the flexible package.
  • a first seam joins the first right side edge portion of the first panel with the second right side edge portion of the second panel.
  • a second seam joins the first left side edge portion of the first panel with the second left side edge portion of the second panel.
  • a third seam joins the first bottom edge portion of the first panel with the second bottom edge portion of the second panel.
  • the pleated portion is provided adjacent to the hooded portion.
  • a first line of weakness is provided in the pleated portion.
  • the flexible reclosable package can be converted from a first, closed configuration to a second, open configuration.
  • the flexible reclosable package may be converted from the first, closed configuration to the second, open configuration upon tearing open the flexible enclosable package along the first line of weakness.
  • the first line of weakness is not visible from the exterior of the package when the package is in the closed configuration.
  • Absorbent articles which may be comprised in the flexible reclosable package, may be disposable and may include diapers, pants, pantiliners, sanitary napkins or absorbent inserts. They may be provided in the flexible reclosable package in a compressed state.
  • the line of weakness By not having the line of weakness being visible from the exterior of the flexible reclosable package when the package is in the first, closed configuration, the risk of inadvertent tearing open the line of weakness is reduced compared to a first line of weakness which is visible -and more easily accessible- from the exterior of the package. Also, the package provides a more aesthetic appearance, as visible first line of weakness may deteriorate the attractiveness of the flexible reclosable package.
  • the reclosable wicketed bags comprise a first panel and a second panel.
  • the first panel defines a first right side edge portion, a first left side edge portion, a first bottom edge portion, and a pleated portion.

  • Absorbent articles which may be comprised in the flexible reclosable package, may be disposable and may include diapers, pants, pantiliners, sanitary napkins or absorbent inserts. They may be provided in the flexible reclosable package in a compressed state.
  • a method of forming a reclosable package includes the step of advancing a continuous length of material in a machine direction, wherein the continuous length of material has a first side and a second side and defines a first edge region and a second edge region separated along a cross direction by a central region.
  • a first line of weakness is formed along the machine direction of the central region of the continuous length of material.
  • intermittently spaced wicket apertures may be formed in the machine direction along the second edge region of the continuous length of material.
  • the continuous length of material is folded along the central region to form a first continuous fold that extends in the machine direction. Additionally, the first continuous panel is folded to form a continuous pleat (corresponding to the pleated portion of the flexible reclosable package that can be obtained by the method).
  • the continuous pleat may comprise second and third continuous folds (corresponding the first and second folds of the pleated portion of the flexible enclosable package that can be obtained by the method) that form first, second, and third overlapping continuous pleated portions (corresponding to the first, second and third layers of the pleated portion of the flexible reclosable package that can be obtained by the method), wherein the second and third continuous pleated portions are positioned between the first continuous pleated portion and the second panel and the third continuous pleated portion is positioned between the first and second continuous pleated portions.

  • the first line of weakness is formed in the second or, more desirably, in the third continuous pleated portion or the first line of weakness is provided substantially in the second continuous fold which is the fold in which the second pleated portion and the third pleated portion converge (i.e. the second continuous fold is between the second and third pleated portions).
  • the second and third continuous folds extend in the machine direction.
  • the continuous length of material is cut in the cross direction to form a discrete flexible enclosable package.
  • a first seam is formed that joins the first right side edge portion of the first panel with the second right side edge portion of the second panel and a second seam is formed that joins the first left side edge portion of the first panel with the second left side edge portion of the second panel.
  • an exemplary package 100 for containing absorbent articles includes a first panel 102 and an opposing second panel 104, shown as a front panel 158 and back panel 160, respectively.
  • the first panel 102 defines a first right side edge portion 106, a first left side edge portion 108, a first bottom edge portion 110, and a pleated portion 114.
  • the second panel 104 defines a second right side edge portion 107, a second left side edge portion 109, a second bottom edge portion 111, and a hooded portion 112.
  • the first and second panels 102 and 104 combine to define an interior 118 and an exterior 120 of the package 100.

  • the package 100 may contain a plurality of absorbent articles 200.
  • Each absorbent article 200 may be folded about a lateral axis 204.
  • Each absorbent article may, alternatively, be folded two times about fold lines substantially parallel to the lateral axis of the absorbent article. In such configurations, the folded absorbent article has two fold lines.
  • each absorbent article may be folded three times about fold lines substantially parallel to the lateral axis of the absorbent article. In such configurations, the folded absorbent article has three fold lines.
  • the absorbent articles may be arranged in rows with one of the two major, outwardly facing surfaces of the absorbent article contacting a major, outwardly facing surface of the adjacent absorbent articles on one side of the row and the other major, outwardly facing surface of the absorbent article contacts a major, outwardly facing surface of the adjacent absorbent article on the opposite side of the row (as is, for example, shown in Fig. 4A ).
  • the term "outwardly facing", as used herein in conjunction with an absorbent article is not to be understood as facing outwardly of the package but is to be understood as not being concealed within the folded absorbent article.
  • Placement of the row or rows of absorbent articles 200 into the interior 118 of the package 100 forms a substantially hexahedral shaped package having a top panel 150, bottom panel 152, front panel 158, back panel 160, left side panel 154, and right side panel 156.
  • the absorbent articles 200 may be compressed to accommodate a relatively large number of articles within the flexible package.
  • compressed articles provide stability to the flexible package filled with the absorbent articles. Improved stability of the package supports stackability of the packages, for example when they are stacked on a pallet for transport or storage.
  • the hooded portion 112 may define the top panel 150 of the package 100.
  • the first panel 102 and a portion of the hooded portion 112 extending from the top panel 150 of the package 100 to the first panel 102 may define the front panel 158 of the package 100.

  • the first and second bottom edge portions 110 and 111 of the first and second panels 102 and 104 may define the bottom panel 152 of the package 100.
  • Such flexible packages are exemplary shown in Figs. 1-4B .
  • the absorbent articles 200 comprised by the interior of the flexible package 100 may be arranged such that their major, outwardly facing surfaces are facing towards the left and right side panels, respectively, of the flexible package.
  • the absorbent article at the beginning of a row will lie against the left side panel 154 and the absorbent article at the end of a row will lie against the right side panel 156 of the flexible package (they may either directly contact the left and right side panel 154, 156 or a sheet, such as a cardboard or paper may be provided between the respective major surface of the absorbent article and the left and right side panel 154, 156 to provide further stability to the flexible package).
  • the absorbent articles are provided in the flexible reclosable package in this manner, repeated opening and closing of the package can be done more easily compared to a package wherein the major, outwardly facing surfaces of the absorbent articles face towards the front and back panel 158, 160 or towards the top and bottom panel 150, 152 of the flexible reclosable package.
  • the hooded portion and a portion of the pleated portion 114 can be easily folded back over the slim, folded edges of the absorbent articles. As more and more absorbent articles are removed from the package, the rows of absorbent articles will start to slant sidewards and the articles in a row are arranged more loosely.
  • the rows of absorbent articles arc arranges such that the major, outwardly facing surfaces of the absorbent articles face towards the front and back panel 158, 160, the slanted absorbent articles may slant towards the front panel 158 and "lean" out of the opened package, which makes reclosing of the package more difficult.
  • a flexible package may comprise (only) one row of absorbent articles (as, e.g., shown in Fig. 4A ).
  • a flexible package may comprise more than one row of absorbent articles.
  • the rows may either be stacked one on top of the other (leading to a flexible reclosable package with higher front and back panel 158, 160 and higher left and right side panels 154, 156 compared to a package with one row), or, the rows may be provided adjacent to each other (leading to a flexible package with wider left and right side panels 154, 156).
