Description

AREA OF INVENTION

[0001] The present invention relates to a method for manufacturing packaging. BACKGROUND

[0002] The category of disposable absorbent products encompasses a wide variety of consumer goods, including diapers, bibs, wipes, sanitary napkins, and tampons. In some cases, the absorbent products are packaged in a primary package, such as a polybag. Multiple primary packages containing absorbent products may be placed inside a secondary package, such as a carton.

[0003] Primary packaging for containing absorbent materials can have opposing first and second panels. Each panel can define a left edge section, a right edge section, a top end section, and a bottom end section. The first and second panels can be joined by a first seam along the right edge sections of the first and second panels and by a second seam along the left edge sections of the first and second panels. The primary packaging can have a handle. The handle can be attached to the packaging at various points. In some packaging, the handle is a separate piece of material that can be attached to the packaging. However, the attached handle may obstruct access to the interior of the packaging.Furthermore, the attached handle may not be durable or aesthetically pleasing to consumers, as it can become creased or wrinkled during transport and use of the packaging. Additionally, attaching a separate handle to the packaging can increase the cost and complexity of the manufacturing process.

[0004] Packaging with handles that suffers from at least one of the aforementioned deficiencies is known from the prior art, for example from US 4,874,255 A, US 5,655,843 A, US 5,121,995 A, and DE 36 44,618 A1. Furthermore, DE 44 19,835 describes packaging with a handle that ensures unimpeded access to the contents and is not particularly prone to creasing or wrinkling, but does not provide the desired mechanical stability when filling the packaging with absorbent materials.

[0005] Therefore, it would be advantageous to provide packaging that includes an integrally formed handle and a method for its manufacture. SUMMARY

[0006] The present invention provides a method for forming packaging. The method according to the invention has the features of independent claim 1. Advantageous embodiments of the method can be found in the dependent claims.

[0010] The following definitions may be helpful in understanding the present invention.

[0011] "Absorbent product" is used herein to refer to consumer products whose primary function is to absorb and retain soiling and excrement. "Diaper" is used herein to refer to an absorbent product generally worn around the abdomen by infants and incontinent individuals. The term "disposable" is used herein to describe absorbent products that are generally not intended to be washed or otherwise restored or reused as absorbent products (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 sound manner).

[0012] "Longitudinal" means a direction running essentially perpendicular from one waist edge to the opposite waist edge of an absorption article when the article is in a flat, uncompressed state, or from a waist edge to the crotch bottom, i.e., the fold line in a simply folded article. Directions within 45 degrees of the longitudinal direction are considered "longitudinal." "Transverse" refers to a direction running from one long side edge to the opposite long side edge of an article, generally at a right angle to the longitudinal direction. Directions within 45 degrees of the transverse direction are considered "transverse."

[0013] "Machine direction" (MD) is used herein to denote the direction of material flow through a process. Furthermore, the relative displacement and movement of material through a process can be described as proceeding in the machine direction from the upstream to the downstream component. "Transverse direction" (CD) is used herein to denote a direction that is not parallel to, and usually perpendicular to, the machine direction.

[0014] This document describes packaging for containing absorbent materials, in particular packaging that includes integrally formed handles. The present invention relates to a method for manufacturing the aforementioned packaging. The packaging can have a first compartment and a second compartment. The first and second compartments each define a right edge section, a left edge section, a first end section, and a second end section. The packaging can include a fold that connects the first end sections of the first and second compartments. The fold defines a right edge section and a left edge section, which are separated from each other by a central section. The fold can include a handle opening in the central section, which forms a handle for the packaging. The first compartment, the second compartment, and the fold together define an interior and an exterior environment of the packaging.A first seam joins the right-hand edges of the first field, the second field, and the fold, and a second seam joins the left-hand edges of the first field, the second field, and the fold. A third seam joins the second end of the first field to the second end of the second field. The first field, the second field, and the fold are formed in one piece.

[0015] The packaging can be configured as resealable pen stacking pouches. The pen stacking pouch can have a first compartment and a second compartment. The first and second compartments each define a right edge section, a left edge section, a first end section, and a second end section. The pen stacking pouch can have a pen compartment connected to the second end section of the second compartment. The pen compartment can include a pen opening. The pen stacking pouch can also have a fold connecting the first end sections of the first and second compartments. The fold defines a right edge section and a left edge section separated by a central section. The fold can include a handle in the central section, forming a handle for the packaging. The first compartment, the second compartment, and the fold together define an interior and an exterior environment of the packaging.A first seam joins the right-hand edge sections of the first panel, the second panel, and the fold, and a second seam joins the left-hand edge sections of the first panel, the second panel, and the fold. The second end section of the first panel and the second end section of the second panel together define an opening in the packaging. The first panel, the second panel, the pin panel, and the fold are formed as an integral unit.

[0016] The present invention comprises a method for forming a pencil stack bag. The method may include the step of advancing a continuous length of material in the machine direction, wherein the continuous length of material defines a first edge region and a second edge region, which are separated along a transverse direction by a third region. A weakening line may be formed along the machine direction of the central region of the continuous length of material. A first and a second row of intermittently spaced handle openings may be formed along the central region of the continuous length of material in the machine direction. The second row of handle openings may be arranged between the first row of handle openings and the weakening line. Intermittently spaced pencil openings may be formed along the second edge region of the continuous length of material in the machine direction.The continuous length of material can be folded transversely along its central region to align the first edge region of the second side of the continuous length with the central region of the second side of the continuous length from top to top. The method can include folding the continuous length of material to form a continuous fold. The continuous fold comprises a first handle opening from the first row of handle openings and a second handle opening from the second row of handle openings, with the first and second handle openings aligned to form a handle.The continuous length of material can be folded to form a first continuous gusset field connected between the first continuous field and the continuous fold, and a second continuous gusset field connected between the continuous fold and the second continuous field.

[0017] The continuous length of material can be cut transversely to form separate packages. A first seam can be formed to join the right-hand edge sections of the first panel, the second panel, and the fold. A second seam can be formed to join the left-hand edge sections of the first panel, the second panel, and the fold. The separate packages can be filled with several absorbent items by inserting the items through the opening in the packages. Next, a third seam can be formed to join the bottom edge sections of the first and second panels. Joining the bottom edge sections of the first and second panels may involve removing the pin from the second panel.

[0018] Absorbent articles of the present disclosure may include diapers, sanitary napkins, adult incontinence products and the like.

[0019] As in Fig. As shown in Figures 1-3, an exemplary package 100 for containing absorbent articles 200 can have a first compartment 102 and a second compartment 104. The first and second compartments 102 and 104 can each define a right edge section 106 and 107, a left edge section 108 and 109, a first end section 110 and 111, and a second end section 112 and 113. The package 100 can have a fold 120 connected between the first end sections 110 and 111 of the first and second compartments 102 and 104. The fold 120 defines a right edge section 122 and a left edge section 124, separated by a central section 126. The fold 120 can have a handle opening 128 in the central section 126, forming a handle 129 for the package 100. The right-hand edge sections 106, 107 and 122 of the first field 102, of the second field 104 respectively.The fold 120 can be joined along a first seam 130, and the left edge sections 108, 109, and 124 of the first field 102, the second field 104, and the fold 120, respectively, can be joined along a second seam 132. A third seam 134 can join the second end section 112 of the first field 102 to the second end section 113 of the second field 104. A fourth seam 135 can join the fold 120 to the first end sections 110 and 111 of the first and second fields 102 and 104. The first field 102, the second field 104 and the fold 120 together define an interior 114 and an outer environment 116 of the packaging 100. The first field 102, the second field 104 and the fold 120 can be formed in one piece.

[0020] As in Fig. 1 and Fig. As shown in Figure 3, the packaging can have a gusset 140 with a first gusset field 142 and a second gusset field 144. In some exemplary configurations, the first gusset field 142 can be connected between the fold 120 and the first end section 110 of the first field 102, and the second gusset field 144 can be connected between the fold 120 and the first end section 111 of the second field 104.

[0021] The packaging may contain several absorbent items. As in Fig. 4A and Fig. As shown in Figure 4B, each absorbent article 200 can be folded about a transverse axis 204 and arranged in one or more horizontal or vertical rows. An arrangement of the row or rows of absorbent articles 200 in the interior 114 of the package 100 forms a substantially hexagonal package 100 with a top box 150, a bottom box 152, a front box 158, a rear box 160, a left box 154, and a right box 156. Referring to Fig. In some example configurations, 1-4B define the fold 120, and the first and second gusset fields 142 and 144 define the top field 150 of the package 100. In such an example configuration, the first field 102 can define the front field 158 of the package 100, and the second field 104 can define the rear field 160 of the package 100. The left edge sections 108 and 109 of the first and second fields 102 and 104 define a left field 154, and the right edge sections 106 and 107 of the first and second fields 102 and 104 define a right field 156. The second end sections 112 and 113 of the first and second fields 102 and 104 can define the bottom field 152 of the package 100.

[0022] Referring to Fig. 1-3 The packaging 100 can be configured such that the lower panel 152 can be supported by a surface, such as a table, a work surface, a floor, a changing table, and the like. However, it should be understood that the packaging 100 can be configured to rest on any of the upper panel 150, lower panel 152, front panel 158, rear panel 160, left panel 154, or right panel 156. Although it is shown that the fold 120 and the first and second gusset panels 142 and 144 form the upper panel 150 of the packaging 100, it should further be understood that the fold 120 can be arranged in various other configurations, such that the fold 120 can define a section of another panel of the packaging 100. For example, in some exemplary configurations, the fold 120 can form a section of the front panel 158, the rear panel 160, or the bottom panel 152 of the packaging 100.

[0023] As described above, the packaging can contain 100 pieces, including one fold. As in Fig. 1 and Fig. As shown in Figure 3, the fold 120 can define a first folded section 136 and a second folded section 138, which are connected at a first fold 174. The first fold 174 can be configured in a C-shape. The first and second folded sections 136 and 138 can each include a handle opening 128a and 128b, respectively. As shown in Fig. As shown in Figure 1, in some exemplary configurations the handle openings 128 can be arranged in the central section 126 of the fold 120. The first folded section 136 can be arranged between the first gusset 142 and the second folded section 138. The first and second folded sections 136 and 138 and the handle openings 128a and 128b together form an integral handle 129 for the package 100. In some exemplary configurations, the package 100 can include one or more folds 120. The handle openings 128 can be configured to be larger than at least two fingers of a human hand. As a result, a user can insert two or more fingers of a hand through the handle openings 128 to carry the package 100. In some exemplary configurations, the handle opening 128 can, for example, have a length L Hin the range of approximately 40 millimeters to approximately 150 millimeters or approximately 50 millimeters to approximately 100 millimeters. In some example configurations, the handle opening can have a width W H For example, they can range from approximately 10 millimeters to approximately 50 millimeters, or from approximately 20 millimeters to approximately 40 millimeters. It should be understood that the handle openings can have 128 different dimensions. It should also be understood that the handle openings can have 128 different shapes, such as rectangles, circles, and ovals. The first and second folded sections 136 and 138, for example, can have a width W. P They range in size from approximately 20 millimeters to approximately 50 millimeters. It should be understood that the handle can have different dimensions.

[0024] The packaging may have one or more expandable gussets. As in Fig. As shown in Figures 1-3, the upper field 150 of the packaging 100 can comprise a gusset 140 with a first gusset field 142 and a second gusset field 144. As shown in Fig. 1 and Fig. As shown in Figure 3, in some exemplary configurations the fold 120 can be connected between the first and second gusset fields 142 and 144. The gusset 140 can define a right edge section 146 and a left edge section 148, separated by a central section 147. The gusset 140 can run from the first seam 130 to the second seam 132. The right edge section 146 of the gusset 140 can be connected to the right edge sections 122, 106 and 107 of the fold 120 or to the first and second fields 102 and 104 at the first seam 130, and the left edge section 148 of the gusset 140 can be connected to the left edge sections 124, 108 and 109 of the fold 120 or to the first and second fields 102 and 104 at the second seam 132.

[0025] Further referring to Fig. 1 and Fig. 3. When filling a package 100 with absorbent items 200, the first and second gusset fields 142 and 144 at the left and right edge sections 146 and 148 of the gusset 140 can be folded and tucked into the interior 114 of the package 100. As a result, the package 100 can be adapted to the shape of the row or rows of absorbent items 200 to prevent movement and / or distortion of the absorbent items 200 during packaging, transport, and use by a consumer. The gusset 140 can be formed integrally with the first field 102, the second field 104, and the fold 120. In an exemplary configuration shown in Fig. 1 and Fig. As shown in Figure 3, the gusset 140 and the fold 120 can define the upper field 150 of the packaging 100. Although in Fig. 1 and Fig. Figure 3 shows that the gusset 140 defines a section of the upper field 150 of the package 100. It should be understood that various other fields of the package 100 can also contain gussets. For example, the right edge sections 106 and 107 of the first and second fields 102 and 104, the left edge sections 108 and 109 of the first and second fields 102 and 104, and / or the second end sections 112 and 113 of the first and second fields 102 and 104 can contain gussets. In some example configurations, the package 100 can have one or more gussets 140.

[0026] The in Fig. The gusset 140 shown allows the fold 120 to lie essentially flat while the handle 129 is not used by a user. This can provide several advantages for a user. Since the handle 129 is integral with the first and second panels 102 and 104, for example, it does not obstruct access to or normal use of the package 100. Furthermore, the integrated handle 129 may be perceived as more durable than a handle attached to the package as a separate component. Additionally, the package 100 can be aesthetically pleasing to consumers because it has a continuous profile with no additional parts or elements protruding from the exterior when not in use. Moreover, the fold 120 remains flat and essentially free of creases or wrinkles.The handle openings 128 also remain in essentially the same position, which may allow the user to easily locate the handle 129 from one use to the next.

[0027] As in Fig. As shown in Figure 1, the packaging 100 can include a weakening line 162. The weakening line 162 can be torn open by a user to gain access to the interior 114 of the packaging 100. The weakening line 162 can be located at different points. The weakening line 162 can run from the first seam 130 to the second seam 132. As shown in Figure 1. Fig. As shown in Figure 1, in some exemplary configurations the weakening line 162 can connect the fold 120 to the second gusset panel 104. In other exemplary configurations, the weakening line 162 can be located at various other locations, including the front panel 158, the rear panel 160, the left or right panels 156 and 154, or the bottom panel 152. The weakening line 162 can pass through one or more panels of the packaging 100. In some exemplary configurations, the packaging 100 can have more than one weakening line 162. As a result, the packaging 100 can be opened at more than one location. The weakening line 162 can include perforations. The weakening line 162 can be formed by perforation, crimping, or various other means to provide a line that is structurally weaker than the sections of the packaging 100 adjacent to the weakening line 162.It should be understood that the weakening line 162 can be strong enough to withstand the transport and use of the package 100, while being weak enough to allow a consumer to open the package 100 upon first use. The package 100 can be sealed before being opened at the weakening line 162. This prevents the package 100 from becoming damp or contaminated until the consumer opens it to remove an absorbent item. That is, the package 100 can remain sealed during transport, storage, and in the store. In some exemplary configurations, the package 100 can be essentially hermetically sealed. For example, the weakening line 162 can be essentially linear, or in other exemplary configurations, the weakening line can be curved.

[0028] A package of 100 can comprise various materials. For example, the packaging can include films made of materials such as polyethylene or polypropylene. In some example configurations, the packaging comprises a polyethylene-polypropylene-polyethylene laminate. In these example configurations, where the packaging includes a laminate, the laminate can be co-extruded. The packaging can have a thickness of approximately 35 micrometers to approximately 50 micrometers or from approximately 40 to approximately 45 micrometers. In an example configuration where a thicker package is desired, the packaging can have a thickness of approximately 55 micrometers to approximately 65 micrometers.

[0029] In some exemplary configurations, packaging components may consist at least partially of biological sources, as described in US 2007 / 0219521A1, Hird et al., published on September 20, 2007, US 2011 / 0139658A1, Hird et al., published on June 16, 2011, US 2011 / 0139657A1, Hird et al., published on June 16, 2011, US 2011 / 0152812A1, Hird et al., published on June 23, 2011, US 2011 / 0139662A1, Hird et al., published on June 16, 2011, and US 2011 / 0139659A1, Hird et al., published on June 16, 2011.

[0030] In at least one exemplary configuration, a package includes a biologically based content of approximately 10% to approximately 100% using ASTM D6866-10, Method B, in another exemplary configuration of approximately 25% to approximately 75%, and in yet another exemplary configuration of approximately 50% to approximately 60% using ASTM D6866-10, Method B.

[0031] To apply the method of ASTM D6866-10 for determining the bio-based content of each package, a representative sample of the package must be provided for testing. In at least one exemplary configuration, the package can be milled to particles with a size of less than approximately 20 mesh using known milling methods (e.g., Wiley® mill), and a representative sample of suitable mass can be taken from the statistically mixed particles.

[0032] In some example configurations, the exterior of the packaging can include 100 different images, colors, text, and the like. Referring to Fig. 1 In some exemplary configurations, the package 100 may have notices printed on the first and / or second fields 102 and 104 of the package 100, such that when the package 100 is positioned with the lower field 152 facing down and the upper field 150 facing up, the notices are oriented upright. Such notices may include words, e.g., brand name, size, product line, advertising, marketing claims, safety information, instructions for use, and the like, and / or graphics, e.g., pictures of users of the absorbent products, caregivers, purchasers of the absorbent products, advertisements, and pictorial representations of safety information and / or instructions for use, and the like.

[0033] To make it easier for consumers to locate weakening line 162, it may be a different color than the packaging. For example, with reference to Fig. 1. A package 100 may be clear, and the weakening line 162 may be colored, such as blue, or otherwise differentiated to draw attention to the weakening line 162. In an exemplary configuration, where one or more packages 100 are arranged inside a secondary package, such as a carton, the secondary package may include cues to draw attention to the weakening line, such as an arrow or the words "Tear Here" printed on the carton corresponding to the position of the weakening line 162. In some exemplary configurations, the fold 120 may have different colors or patterns than the rest of the package. For example, in one such exemplary configuration, the fold 120 may be clear, while the rest of the package 100 includes one color and / or a pattern of colors. In other exemplary configurations, the fold 120 may be a different color than the rest of the package 100.Furthermore, the packaging may include 100 instructions that draw attention to the fold 120 of the packaging 100 and / or show how to use the handle 129. For example, an image may include a hand and a perspective view of the packaging, showing a hand holding the packaging by the handle.

[0034] In some example configurations, the packaging can be configured to be resealable. For example, as in Fig. As shown in Figure 5, the second field 104 of the package 100 can contain a concealed section 164. A weakening line 162a can connect the first and second fields 102 and 104. To open the package 100, the weakening line 162a is torn. With the weakening line 162a torn, the concealed section 164 can be in a first, closed configuration, as shown in Figure 5. Fig. 6 shown, or a second, open configuration, as shown in Fig. Figure 7 shows the configuration. To arrange the package 100 in the second configuration, the concealed section 164 is removed from the first compartment 102 to expose the absorbent items 200 contained therein. To arrange the package 100 from the second configuration to the first configuration, the concealed section 164 can be moved to the first compartment 102 to cover the absorbent items that remain contained therein. Exemplary resealable packages are described in U.S. Patent Application No. 12858 entitled “RECLOSABLE PACKAGE AND A METHOD OF MAKING THE SAME”, filed May 22, 2013.

[0035] As in Fig. 8A, Fig. 8B and Fig. As shown in Figure 9, the packaging 100 can be configured as a pin stacking bag 166 before the insertion of absorbent articles into the packaging 100. The pin stacking bag 166 can have a first compartment 102 and a second compartment 104. The first and second compartments 102 and 104 each define a right edge section 106 and 107, a left edge section 108 and 109, a first end section 110 and 111, and a second end section 112 and 113. The pin stacking bag 166 can have a pin compartment 168 that is connected to the second end section 113 of the second compartment 104. The pin compartment 168 can include a pin opening 170. The pin stacking bag 166 can have a fold 120 that is connected between the first end sections 110 and 111 of the first and second compartments 102 and 104. The fold 120 defines a right edge section 122 and a left edge section 124, which are separated by a middle section 126.The fold 120 can include a handle opening 128 in the middle section 126, which forms a handle 129 for the packaging 100. The first field 102, the second field 104, and the fold 120 together define an interior 114 and an outer environment 116 of the packaging 100. A first seam 130 joins the right edge sections 106, 107, and 122, respectively, of the first field 102, the second field 104, and the fold 120, and a second seam 132 joins the left edge sections 108, 109, and 124, respectively, of the first field 102, the second field 104, and the fold 120. The second end section 112 of the first field 102 and the second end section 113 of the second field 104 together define an opening 172 in the packaging 100. The first field 102, the second field 104, the pin field 168, and the fold 120 can be formed integrally. The pin field 168 includes at least one pin opening 170. As in . Fig. 8A and Fig. As shown in Figure 8B, the pin array 168 has two pin openings 170. As discussed in more detail below, each pin opening 170 can be configured to receive a pin. The pin openings 170 can be configured in various shapes. As shown in Fig. 8A and Fig. As shown in Figure 8B, the pin openings 170 can be essentially circular.

[0036] As explained above and as in Fig. 8A, Fig. 8B and Fig. As shown in Figure 9, the pen stacking bag 166 can include an expandable gusset 140. The gusset 140 can be integrally formed with the first compartment 102, the second compartment 104, and the fold 120. In an exemplary configuration shown in Figure 9, the pen stacking bag 166 can include an expandable gusset 140. The gusset 140 can be formed integrally with the first compartment 102, the second compartment 104, and the fold 120. Fig. 8A, Fig. 8B and Fig. As shown in Figure 9, the gusset 140 can have a first gusset field 142 and a second gusset field 144. The first gusset field 142 can be connected to the first field 102 at a second fold 176, and the first gusset field 142 can be connected to the fold 120 at a third fold 178. The second gusset field 144 can be connected to the fold 120 at a fourth fold 180, and the second gusset field 144 can be connected to the second field 104 at the fifth fold 182. The second, third, fourth, and fifth folds can be configured as C-shaped folds.

[0037] As in Fig. 10A and Fig. As shown in Figure 10B, in some exemplary configurations the fold 120 can be positioned away from the gusset 140. Referring to Fig. 1 and Fig. It should be understood that in such an exemplary configuration, the fold 120 can define a section of the front panel 158 of the packaging 100, and the gusset 140 can define the upper panel 150 of the packaging 100. It should also be understood that the fold 120 can be configured at different locations on the packaging 100, depending on the desired position of the handle 129.

[0038] As in Fig. As shown in Figure 11, several pin stack bags 166 can be stacked on top of each other such that the pin openings 170 of each pin stack bag 166 are flush. A pin 184 can pass through the pin openings 170 to hold the stack of bags together. In an exemplary configuration where each pin stack bag 166 in a stack has two pin openings 170, two pins 184 can be used. Different types of pins 184 can be used to hold a stack of pin stack bags 166 together. As discussed in more detail below, the several pin stack bags are held together by the pins, while the absorbent items are introduced through the opening into the pin stack bag. Once the bag is filled with absorbent items, the first and second sections can be welded together at a third seam, and the pin section can be cut out of the second section.

[0039] A resealable pencil stacking bag can be formed from a single continuous length of material. As in Fig. As shown in Figure 12, a method for producing a pencil stack pouch can include advancing a continuous length of material 210 in a machine direction MD. The continuous length of material 210 has a first side 212 and an opposite second side 214 and can define a first edge region 216 and an opposite second edge region 218, which are separated from each other along a transverse direction CD by a central region 220. The continuous length of material can comprise a thermoplastic film, such as a polyethylene or polypropylene film.

[0040] The continuous material length 210 can be subjected to various processes while being moved forward in the machine direction MD. For example, as in Fig. As shown in Figure 13, a continuous weakening line 222 can be formed in the continuous material length 210. The weakening line 222 can run along the machine direction MD and can be located at various transverse direction points (CD). As shown in Fig. As shown in Figure 13, in some exemplary configurations the weakening line 222 can run in the machine direction MD along the central region 220 of the continuous material length 210. The weakening line 222 can be formed in various ways, such as by perforating, crimping, embossing, and the like, to provide a line that is structurally weaker than the other sections of the packaging. The weakening line 222 can be configured in various ways. For example, the weakening line 222 can be essentially linear, or in other exemplary configurations, the weakening line can be curved.

[0041] As in Fig. As shown in Figure 14, intermittently spaced pin openings 170 can be formed in the continuous material length 210 along the machine direction MD in a further step. The pin openings 170 can be arranged at various transverse locations (CD) of the continuous material length 210. In some exemplary configurations, the pin openings 170 can be formed in the second edge region 218 of the continuous material length 210. The pin openings 170 can be intermittently spaced at different increments in the machine direction MD. Various methods can be used to form the pin openings 170, including various mechanical or thermal cutting processes, such as punching or laser cutting. The pin openings 170 can be dimensioned such that a pin passes through each pin opening.

[0042] Furthermore, as in Fig. Figure 15 shows a first and a second row 224a and 224b of intermittently spaced grip openings 128a and 128b formed in the continuous material length 210 along the machine direction MD. The grip openings 128 can be arranged at various transverse locations. In some exemplary configurations, as shown in Fig. As shown in Figure 15, the first and second rows 224a and 224b of grip openings 128a and 128b can be formed along the central region 220 of the continuous material length 210. The grip openings 228 can be intermittently spaced at various increments in the machine direction MD. Various methods can be used to form the grip openings 228, including various mechanical or thermal cutting operations, such as punching or laser cutting. The grip openings 228 can be dimensioned to allow at least two fingers and / or the palm of a human hand to be inserted through them. The steps of forming the pin openings 170 and the grip openings 228 can be performed simultaneously or, in some exemplary configurations, sequentially.

[0043] Referring to Fig. 16 and Fig. 17. The continuous material length 210 can be folded in the transverse direction CD along the central region 220 to form a first continuous field 226 and a second continuous field 228, which are connected along a first continuous fold 230. The first continuous fold 230 can run in the machine direction MD. The first continuous fold 230 can be configured in a C-shape. The second sides 214 of the first and second continuous fields 226 and 228 can be arranged top-to-top. The first fold 230 can be located at various positions relative to the first and second edge regions 216 and 218 of the continuous material length 210. Thus, in some exemplary configurations, the first fold 230 can be located equidistant from the first and second edge regions 216 and 218.In other exemplary configurations, the first fold 230 can be located relatively closer to either the first or the second edge region 216 or 218. In some exemplary configurations, as in . Fig. As shown in Figure 16, the first continuous fold 230 can be arranged between the first and second rows 224a and 224b of the handle openings 128. In such an exemplary configuration, folding the continuous material length 210 around the first continuous fold 230 can align the handle openings 128a of the first row 224a with the handle openings 128b of the second row 224b.

[0044] In an exemplary configuration, which is in Fig. 16 and Fig. As shown in Figure 17, after folding the continuous material length 210 around the first continuous fold 230, a continuous seam 254 can be formed near the first and second rows 224a and 224b of grip openings 128 along the machine direction MD. The first and second rows 224a and 224b of grip openings 128 can be arranged between the first continuous fold 230 and the continuous seam 254. As a result, a continuous fold 232 is formed in the continuous material length 210. The continuous fold 232 can have a first continuous folded section 238 and a second continuous folded section 240, which are connected along the first continuous fold 230. The first folded section 238 can have the first row 224a of handle openings 128, and the second folded section 240 can have the second row 224b of handle openings 128.The first folded section 238 and the second folded section 240 can be configured in a top-to-top relationship in substantially parallel planes.

[0045] Referring to Fig. 18 and Fig. 19 The continuous material length 210 can be folded to form a first continuous gusset 248. In particular, a section of the first side 212 of the continuous material length 210 can be guided to the first folded section 238 of the continuous fold 230 such that the second and third continuous folds 234 and 236 are formed along the machine direction MD. The second and third continuous folds 234 and 236 can be formed at different transverse directions CD. The second and third continuous folds 234 and 236 can be configured as C-shaped folds. The continuous seam 254 can run adjacent to the third continuous fold 236.

[0046] Referring to Fig. 20 and Fig. In some exemplary configurations, a second continuous gusset 250 can be formed in the continuous material length 210. To form the second continuous gusset 250, the continuous material length 210 can be folded by folding a section of the first side 212 of the continuous material length 210, which includes the second folded section 240 of the continuous fold 232, to another section of the first side 212 of the continuous material length 210, so that a fourth continuous fold 244 and a fifth continuous fold 246 are formed along the machine direction MD. When folding the continuous material length 210 to form the second continuous gusset 250, the second continuous field 228 can extend beyond the first continuous field 226 in the transverse direction CD. As shown in Fig. Figure 21 shows an exemplary configuration in which the continuous fold 232 is connected between the first and second continuous gussets 248 and 250, the first continuous gusset 248 is connected between the second continuous fold 234 and the third continuous fold 236, and the second continuous gusset 250 can be connected between the fourth and fifth continuous folds 244 and 246.

[0047] In some exemplary configurations, the first and second continuous gussets 248 and 250 and the continuous fold 232 can each run in the machine direction MD. Thus, the same or similar equipment can be used to fold the continuous length of material 210 to form the first and second continuous gussets 248 and 250 and the continuous fold 232. Furthermore, a production line configured to produce a pencil stacking bag with a gusset may require only minimal modifications to produce a pencil stacking bag with both an integrated handle and a gusset. In some exemplary configurations, the first and second continuous gussets 248 and 250 and the continuous fold 232 can be formed simultaneously.In other exemplary configurations, the first and second continuous gussets 248 and 250 and the continuous fold 232 can be formed successively.

[0048] Referring to Fig. 20 and Fig. In another step, the continuous material length 210 can be cut in the transverse direction CD between adjacent handle openings 128 to form separate pen stack pouches 166. The continuous material length 210 can be cut using various cutting devices, such as a knife-shaft cross cutter, a punch, or a laser cutter.

[0049] The process of forming pencil stack bags 166 may include the step of seam joining between the right and left edge sections of the first field, the second field, the fold, and the gusset. Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 22 A first seam 130 can be formed in the right edge sections 106, 107, 122, and 146 of the first field 102, the second field 104, the fold 120, and the gusset 140, respectively. A second seam 132 can be formed in the left edge sections 108, 109, 124, and 148 of the first field 102, the second field 104, the fold 120, and the gusset 140, respectively. The first and second seams 130 and 132 can be formed in various ways, including ultrasonic welding, hot air joining, adhesives, and the like. In some exemplary configurations, the steps of cutting the continuous material length 210 to form separate pen stack bags 166 and forming the first and / or second seams 130 and 132 can be performed simultaneously. In other exemplary configurations, the cutting and seam joining steps can be performed sequentially.

[0050] Referring to Fig. 8A, Fig. 9 and Fig. An opening 172 is defined by the second end sections 112 and 113 of the first and second fields 102 and 104. The pencil stacking bags 166 can be filled with absorbent materials by inserting the absorbent materials through the opening 172. As explained above, the absorbent materials can be folded about a transverse axis before being inserted into the pencil stacking bag. The absorbent materials can be arranged in a row, with the folded end of the absorbent materials facing the gusset 140 of the pencil stacking bag. In some exemplary configurations, two or more rows of absorbent materials can be inserted into the pencil stacking bag 166.

[0051] Referring to Fig. 3 and Fig. Once the pen stacking bag 166 is filled with absorbent items, the second end sections 112 and 113 of the first and second fields 102 and 104 can be folded together to form a third seam 134. Like the first and second seams 130 and 132, the third seam 134 can be formed in various ways.

[0052] Furthermore, the pen field 168 can be cut out from the second field 104 to make the packaging 100 as shown in Fig. 1 and Fig. 2 shown. In some exemplary configurations, the steps of forming the third seam 134 and cutting the pin field 168 can be performed simultaneously. In other exemplary configurations, the steps of forming the third seam 134 and cutting the pin field 168 can be performed sequentially. Various methods can be used to cut the pin field 168 out of the second field 104. Exemplary cutting devices include knife rollers, punches, and lasers. As shown in Fig. 4A and Fig. As shown in Figure 4B, the packaging 100 can generally have the form of the series of absorption articles 200 contained therein.

[0053] It should be understood that the steps described above for forming a pencil stack bag can be performed in different orders. Furthermore, some steps may overlap or occur simultaneously, while others are performed sequentially.
