Description

FIELD

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.

BACKGROUND

The field of disposable absorbent articles includes a wide variety of consumer products, including diapers, bibs, wipes, sanitary napkins, tampons, etc. In some cases, the absorbent articles are packaged in a primary package, such as a polybag. A plurality of primary packages containing absorbent articles may be packaged in a secondary package, such as a cardboard box.
Primary 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. In some primary packages, the reclosable features may include a lid, tape tab fastener, hook and loop fastener, snap, button, or latch, for example. However, adding reclosable features to the primary package may add cost and complexity to the manufacturing of the package.
Some primary 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. However, 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 primary package for inserting absorbent articles during the packaging process, and for removing the absorbent articles from the primary package at the time of use by the consumer. Without using additional refastenable features, the package may not be sealed at the time of purchasing the primary 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.
Therefore, it would be beneficial to provide a reclosable primary package that is sealed at the time of purchase. Moreover, it would be beneficial to provide a primary package that is reclosable without the need for additional reclosable features. Additionally, it would be beneficial to provide a sealed reclosable package that is able to be filled with absorbent articles using automated packaging processes.

DETAILED DESCRIPTION

The following definitions may be useful in understanding the present disclosure.
“Absorbent article” is used herein to refer to consumer products whose primary function is to absorb and retain soils and wastes. “Diaper” is used herein to refer to an absorbent article generally worn by infants and incontinent persons about the lower torso. The term “disposable” is used herein to describe absorbent articles which generally are not intended to be laundered or otherwise restored or reused as an absorbent article (for example, 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).
“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. Directions within 45 degrees of the longitudinal direction are considered to be “longitudinal.” “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. Directions within 45 degrees of the lateral direction are considered to be “lateral.”
“Machine direction” (MD) is used herein to refer to the direction of material flow through a process. In addition, 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.
The present disclosure relates to reclosable packages for containing absorbent articles, and more particularly, relates to sealed reclosable packages and methods of making and using the same. Reclosable packages of the present disclosure may include a first panel and an opposing second panel. The first panel defines a right side edge portion, a left side edge portion, a bottom edge portion, and a pleated portion. The second panel defines a right side edge portion, a left side edge portion, a bottom edge portion, and a hooded portion. The first and second panels combine to define an interior and an exterior of the package. A first seam joins the right side edge portion of the first panel with the right side edge portion of the second panel. A second seam joins the left side edge portion of the first panel with the left side edge portion of the second panel. A third seam joins the bottom edge portion of the first panel with the bottom edge portion of the second panel. A line of weakness joins the pleated portion of the first panel with the hooded portion of the second panel. Upon opening the package at the line of weakness, the hooded portion may be configured in a first configuration and a second configuration. In the first configuration, the hooded portion is arranged adjacent to the pleated portion. In the second configuration, the hooded portion is arranged away from the pleated portion to form an opening in the package. Absorbent articles of the present disclosure may include diapers, feminine pads, adult incontinence products, and the like.
Packages of the present disclosure may be configured as reclosable wicketed bags. The reclosable wicketed bags may comprise a first panel and a second panel. The first panel may define a right side edge portion, a left side edge portion, a bottom edge portion, and a pleated portion. The second panel may define a right side edge portion, a left side edge portion, a bottom edge portion, and a hooded portion. The wicketed bag may comprise a wicket panel extending from the bottom edge portion of the second panel. The first and second panels combine to define an interior and an exterior of the package. A first seam joins the right side edge portion of the first panel with the right side edge portion of the second panel. A second seam joins the left side edge portion of the first panel with the left side edge portion of the second panel. A line of weakness joins the pleated portion of the first panel with the hooded portion of the second panel. The wicket panel comprises a wicket aperture. The bottom edge portion of the first panel and the bottom edge portion of the second panel combine to define an opening in the package.
A method of forming a reclosable package may include 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 third region. A line of weakness may be formed along the machine direction of the central region of the continuous length of material. In some exemplary configurations, 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 may be folded along the central region to form a first continuous fold that extends in the machine direction. Additionally, the first continuous panel may be folded to form a continuous pleat. The continuous pleat may comprise second and third continuous folds that form first, second, and third overlapping continuous pleated portions, wherein the second and third continuous pleated portions are positioned between the first continuous pleated portion and the second panel. The line of weakness overlaps the second continuous pleated portion. The second and third continuous folds extend in the machine direction. Next, the continuous length of material may be cut in the cross direction to form a discrete package. A first seam may be formed that joins the right side edge portion of the first panel with the right side edge portion of the second panel and a second seam may be formed that joins the left side edge portion of the first panel with the left side edge portion of the second panel.
As shown in FIGS. 1-3, an exemplary package 100 for containing absorbent articles may include a first panel 102 and an opposing second panel 104, shown as a front panel and back panel, respectively. The first panel 102 defines a right side edge portion 106, a left side edge portion 108, a bottom edge portion 110, and a pleated portion 114. The second panel 104 defines a right side edge portion 107, a left side edge portion 109, a 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. A first seam 122 joins the right side edge portion 106 of the first panel 102 with the right side edge portion 107 of the second panel 104. A second seam 124 joins the left side edge portion 108 of the first panel 102 with the left side edge portion 109 of the second panel 104. A third seam 126 joins the bottom edge portion 110 of the first panel 102 with the bottom edge portion 111 of the second panel 104. The package 100 comprises a line of weakness 116 that joins, and at the same time demarcates, the pleated portion 114 of the first panel 102 with the hooded portion 112 of the second panel 104. The line of weakness 116 may extend contiguously with the pleated portion 114 from the right side edge portion 106 of the first panel 102 to the left side edge portion 108 of the first panel 102. The first, second, and/or third seams may be formed in various ways.
As shown in FIGS. 4A and 4B, the package 100 may contain a plurality of absorbent articles 200. Each absorbent article 200 may be folded about a lateral axis 204 and may be arranged in a horizontal or vertical row or rows. 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. With reference to FIGS. 1-4B, the hooded portion 112 may define the top panel 150 of the package 100. In some exemplary configurations, 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 left side edge portions 108 and 109 of the first and second panels 102 and 104 may define the left side panel 154 of the package 100 and the right side edge portions 106 and 107 the first and second panels 102 and 104 may define the right side panel 156 of the package 100. The 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.
With reference to FIGS. 1, 2, 4A, and 4B, the package 100 may be configured such that the bottom panel 152 may be supported by a surface such as a table, countertop, floor, changing table, and the like. However, it is to be appreciated that the package 100 may be configured to rest on any of the top panel 150, bottom panel 152, front panel 158, back panel 160, left side panel 154, or right side panel 156. Further, while it is shown that the hooded portion 112 defines the top panel 150 of the package 100 and the first panel 102 and a portion of the hooded portion 112 define the front panel 158, it is to be appreciated that the hooded portion 112 of the second panel 104 and the pleated portion 114 of the first panel 102 may be arranged in various configurations such that the hooded portion 112 and the pleated portion 114 define various parts of the package 100. For example, in some exemplary configurations, the hooded portion 112 may define the back panel 160, right side panel 156 or left side panel 154 of the package 100.
With reference to FIG. 1, prior to opening the package 100 at the line of weakness 116, the package 100 may be sealed. Thus, the package 100 may be prevented from tampering or contamination until the consumer opens the package 100 to remove the first absorbent article. That is, during shipping, storage, and while at the store, the package 100 may remain sealed. In some exemplary configurations, the package 100 may be substantially hermetically sealed. As discussed in more detail below, upon opening the package 100 at the line of weakness 116, the hooded portion 112 may be configured from a first, closed configuration to a second, open configuration and back to the first, closed configuration in order to prevent contamination in between uses.
As shown in FIGS. 1 and 3, the hooded portion 112 may define the top panel 150 of the package 100 and may define a portion of the front panel 158 of the package 100. As such, the first and second seams 122 and 124 may each join the hooded portion 112 with another portion of the second panel 104. Upon opening the package 100 along the line of weakness 116, the hooded portion 112 may be arranged in a first configuration and a second configuration. As shown in FIG. 5, in the first configuration, the package 100 is substantially closed such that the hooded portion 112 is positioned adjacent to the pleated portion 114. As shown in FIG. 6, in the second configuration, the hooded portion 112 is located away from the pleated portion 114 such that a first opening 142 is formed in the package 100. As shown in FIG. 7, the hooded portion 112 may be opened in various degrees to expose different amounts of the absorbent articles 200 contained within the package 100.
As shown in FIGS. 1 and 3, in some exemplary configurations, the pleated portion 114 may be integral with the first panel 102. In such an exemplary configuration, the pleated portion 114 may comprise first and second folds 162 and 164 that form first, second, and third layers 166, 168, and 170, respectively. The first layer 166 is arranged proximate to the exterior 120 of the package 100 and the second layer 168 is arranged proximate to the interior 118 of the package 100. The third layer 170 separates the first and second layers 166 and 168. The first and third layers 166 and 170 may be joined at the first fold 162 and the second and third layers 168 and 170 may be joined at the second fold 164. The first and second folds 162 and 164 may be configured in a C-shape. In some exemplary configurations, the entire package 100, including the first and second panels 102 and 104, may be integrally formed from a single piece of material.
With reference to FIG. 3, the hooded portion 112 defines a width, W_H, and the first panel 102 defines a width, W_FP, in the front panel 158 of the package 100. In some exemplary configurations, the width, W_Hof the hooded portion 112 may be less than the width, W_FP, of the first panel 102. Or, in other exemplary configurations, the width, W_Hof the hooded portion 112 may be greater than the width, W_FP, of the first panel 102. A portion of the hooded portion 112 of the second panel 104 may overlap the third layer 170 and/or second layer 168 of the pleated portion 114 to define an overlap portion 140 of the hooded portion 112. The overlap portion 140 may have various widths W_O. For example, the width W_Oof the overlap portion 140 may be greater than 5 millimeters, or may be in the range of 10 to 100 millimeters. It is to be appreciated that the greater the width W_Oof the overlap portion 140, the more the package 100 is actually and/or perceived to be closed in the second, closed configuration. The first, second, and third layers 166, 168, and 170 of the pleated portion 114 may have various widths. For example, the first, second, and third layers 166, 168, and 170 may have a width of greater than about 5 millimeters, or may have a width in the range of about 10 millimeters to about 200 millimeters.
In other exemplary configurations, as shown in FIGS. 8 and 9, the pleated portion 114 may comprise one or more pieces of material that are separate from the remainder of the first panel 102. For example, as shown in FIG. 9, in some an exemplary configuration, the pleated portion 114 may comprise first, second, and third layers 166, 168, and 170 that may be joined by a seam 144 that extends from the right side edge portion 106 of the first panel 102 to the left side edge portion 108 of the first panel 102. The seam 144 may be positioned proximate to the line of weakness 116 in the first panel 102 such that the package 100 is sealed prior to opening the package 100 at the line of weakness 116. In some exemplary configurations, the pleated portion 114 may comprise first and second layers 166 and 168 without the third layer 170 shown in FIG. 9. The pleated portion 114 may comprise the same or similar materials as the remainder of the first panel 102 and/or the second panel 104. In other exemplary configurations, the pleated portion 114 may comprise different materials as the first and/or second panels 102 and 104.
As shown in FIGS. 1-3, the line of weakness 116 may extend from the right side edge portion 106 of the first panel 102 to the left side edge portion 108 of the first panel 102. In such an exemplary configuration, the line of weakness 116 may be positioned in various locations relative to the top panel 150 and bottom panel 152 of the package 100. It is to be appreciated that the closer the line of weakness 116 is to the bottom edge portion 110 of the first panel 102, the greater the width, W_H, of the hooded portion 112 in the front panel 158 of the package 100. With reference to FIG. 6, the closer the line of weakness 116 is to the bottom edge portion 110 of the first panel 102, the more exposed the absorbent articles 200 are through the first opening 142 in the package 100 when the hooded portion 112 is configured in the second, open configuration. It is to be appreciated that the line of weakness 116 may be arranged in various positions and configured in various ways. The line of weakness 116 may be positioned in the front panel 158, back panel 160, right and left side panels 156 and 154, or the bottom panel 152. The line of weakness 116 may extend through one or more panels of the package 100. In some exemplary configurations, the package 100 may include more than one line of weakness 116. As a result, the package 100 may comprise more than one first opening. As shown in FIG. 1, the line of weakness 116 may be substantially linear. However, in other exemplary configurations, the line of weakness 116 may be curved. In some exemplary configurations, the line of weakness 116 may be configured in various other shapes.
The line of weakness 116 may be ruptured by a user to gain access to the interior 118 of the package 100. The line of weakness 116 shown in FIG. 1 is configured with perforations. However, the line of weakness 116 may comprise perforations, crimps, or the like that provide a line that is weaker in structure as compared to the portions of package 100 adjacent to the line of weakness 116. It is to be appreciated that the line of weakness 116 may be strong enough to withstand shipping and handling of the package 100 without rupture, while being weak enough for a consumer to rupture the line of weakness 116 at the time of first use of the package 100.
With reference to FIGS. 1, 3, and 10, the hooded portion 112 may comprise one or more expandable gussets 128. In some exemplary configurations, the top panel 150 of the package 100 may comprise a gusset 128 having a first gusset panel 130 and a second gusset panel 132. The gusset 128 may be integrally formed with hooded portion 112 of the second panel 104. The gusset 128 may define a right side edge portion 134 and a left side edge portion 136 separated by a central portion 138. The gusset 128 may extend from the right side edge portion 107 of the second panel 104 to the left side edge portion 109 of the second panel 104. The right side edge portion 134 of the gusset 128 may be joined with the hooded portion 112 at the first seam 122 and the left side edge portion 136 of the gusset 128 may be joined with the hooded portion 112 at the second seam 124. As the package 100 is filled with absorbent articles, the right and left side edge portions 134 and 136 of the gusset 128 may become folded and tucked in toward the interior 118 of the package 100 as shown in FIG. 10. As a result, the package 100 may conform to the shape of the row or rows of absorbent articles 200 to prevent movement and/or distortion of the absorbent articles 200 during packing, shipping, and use by a consumer. While it is shown in FIG. 1 that the hooded portion 112 may comprise a gusset 128, it is to be appreciated that various other portions of the package 100 may comprise gussets. For example, the right side edge portions 106 and 107 of the first and second panels 102 and 104, the left side edge portions 108 and 109 of the first and second panels 102 and 104, and/or the bottom edge portions 110 and 111 of the first and second panels 102 and 104, may comprise a gusset.
With reference to FIGS. 1 and 2, the packages 100 of the present disclosure may comprise various materials. For example, the packages 100 may comprise films made from materials such as polyethylene or polypropylene, for example. In some exemplary configurations, package 100 comprises a polyethylene-polypropylene-polyethylene laminate. In those exemplary configurations where the package 100 comprises a laminate, the laminate may be co-extruded. The package 100 may have a thickness from about 35 microns to about 50 microns, or from about 40 to about 45 microns.
