FIELD

[0002] The present disclosure relates to a resealable bag enclosure.

BACKGROUND

[0003] Resealable bags may be used for several purposes. Often resealable bags are used for containing liquids, food items, etc. As an example, a resealable bag may be used for cereal. In particular, cereal bags are typically made from a film that that is folded over and sealed to itself. To open the cereal bag, each side of the film may be grabbed and pulled apart at one end. After the cereal bag is opened and cereal dispensed, and a consumer may then roll the open end of the bag up, use a bag clip, empty all of the cereal into a sealable container, or the like. These are all methods that may be undertaken to keep the cereal fresh and to prevent the cereal from going stale.

[0004] Some bags may include a zipper assembly at an end that may be pulled apart and then resealed. By providing for resealing the end, the contents in the bag may be kept fresher without having use a clip, or use a secondary container. In some embodiments, the seal does not go the length of the film, decreasing the opening that needs to be resealed. However, often individuals opening such bags provide too much force, resulting in tearing of the bag past the zipper assembly, resulting in an opening that cannot be resealed.

BRIEF DESCRIPTION [0005] In one or more embodiments of the subject matter described herein, a resealable bag enclosure may be provided that includes a film having an opposing first side and second side coupled with each other along opposite first and second edges and a bottom edge that extends between the first and second edges, and a resealable zipper assembly coupled with the first side and the second side of the film. The first side and the second side of the film together may form a pattern at an opening stop location disposed between the first and second edges of the film and adjacent to an end of the zipper assembly. The pattern of the first side and the second side of the film may also resist opening of the resealable bag enclosure beyond the end of the zipper assembly when the first side and the second side of the film are pulled apart. The resealable bag enclosure may also include a peel seal formed between the first side and the second side of the film above the zipper assembly, the first side and the second side of the film forming the pattern in the peel seal with the pattern in the peel seal oriented in a different direction than a pattern of the zipper assembly formed between the first side and the second side at the opening stop location to prevent the peel seal from extending beyond the pattern in the peel seal oriented in a different direction.

[0006] In one or more embodiments of the subject matter described herein, a resealable bag enclosure is provided that may include a film having an opposing first side and second side coupled with each other along opposite first and second edges and a bottom edge that extends between the first and second edges, the film having a peel seal between the sides of the film and extending from the first edge of the film to an opening stop location, and a resealable zipper assembly coupled with the first side and second side of the film, the zipper assembly extending in a first direction on the first side of the film from an end of the zipper located adjacent to the stop location to and around the first edge and back to the end of the zipper along the first direction on the second side of the film, the zipper assembly providing a resealable enclosure bounded by the sides of the film, the first and second edges of the film, and the bottom edge of the film. The first side and the second side of the film may form a pattern at the stop location, the pattern formed by elongated members in the first side and the second side of the film that are elongated in a second direction that is different from the first direction in which the zipper assembly extends.

[0007] In one or more embodiments of the subject matter described herein, a resealable bag enclosure is provided that may include a film having opposing sides coupled with each other along opposite first and second edges, and coupled with each other along a bottom edge that extends between the first and second edges, the film having a peel seal between the sides of the film and extending from the first edge of the film to an opening stop location, the film having first intermeshing members elongated in a first direction in the peel seal. The resealable bag enclosure may also include a resealable zipper assembly coupled with the opposing sides of the film, the zipper assembly extending from the first edge of the film along each of the opposing sides to an end of the zipper assembly at the opening stop location, the zipper assembly providing access into an interior of the resealable bag enclosure. The opposing sides of the film may form second intermeshing members elongated in a second direction that is different from the first direction in the opening stop location, the second intermeshing members restricting opening of the resealable bag enclosure beyond the end of the zipper assembly.

[0008] The present inventive subj ect matter will be better understood from reading the following description of non-limiting embodiments, with reference to the attached drawings (which are not necessarily drawn to scale), wherein below:

[0009] Figure 1 illustrates a perspective view of a resealable bag in accordance with one or more embodiments of the inventive subject matter described herein;

[0010] Figure 2 illustrates a partial perspective view of a resealable bag as described herein; and

[0011] Figure 3 a flowchart of a method of manufacturing a resealable bag in accordance with one embodiment. DETAILED DESCRIPTION

[0012] One or more embodiments of the inventive subject matter described herein provide a resealable bag formed to have a zipper assembly that opens less than all of an end of the bag (e.g., half of the bag end) while providing protection against ripping or tearing the bag past the zipper assembly. The zipper assembly may have a peal seal that extends along an end of the bag. The peal seal may include a first portion that may be opened along the axis that the peal seal extends. The peal seal may also include a second portion that is orthogonal to the first portion at a stop location that prevents ripping or tearing of the bag after the first portion is opened. The pattern of the second portion resists additional force. To this end, on the opposite side of the stop location from the peal seal are relief areas for absorbing additional pressure resulting from force occurring when the peal seal is opened. Because the second portion of the peal seal is orthogonal to the first portion at the stop location, and because of the relief areas, undesired tearing of the bag past the peal seal opening is reduced.

[0013] Figure 1 illustrates one example of a resealable bag enclosure 110. The resealable bag enclosure may be used to store liquids, solids, food items, etc. In one resealable bag enclosure 110 example, the resealable bag contains cereal. The is formed from a film 112 having a top edge 114 and opposite bottom edge 116. The film 112 also includes opposite first edge 118 and second edge 120 that each extend from the top edge 114 to the bottom edge 116. Extending from the first edge 118 and second edge 120 are opposing first and second sides 122 and 124 that do not engage one another. In this manner, the film 112 forms an enclosure above the bottom edge 116 and between the first and second edges 118 and 120. The film 112 may be formed from plastic, nylon, ceramic material, or the like.

[0014] Extending at one of the top edge 114, or bottom edge 116, is a zipper assembly 128 that may be coupled to the opposing first and second sides 122, 124. The zipper assembly 128 may include opposing teeth, groove and protrusion, matching patterns, low strength adhesive, etc. Disposed above the zipper assembly 128 may be a peal seal 130. The peal seal 130 may be joined to the film 112 and extend from the first edge 118 and terminate between the first edge 118 and second edge 120 at a stop location 134. In one example, the stop location 134 may be at a midpoint between the first edge 118 and the second edge 120. Alternatively, the stop location 134 may be located closer to the first edge 118, or to the second edge 120, yet still spaced apart from the respective edge 118 or 120.

[0015] At the stop location 134 a pattern may run orthogonal, or perpendicular, to the peal seal 130 to provide a stop element. While in one example the peal seal 130 has the same pattern as the stop element, in other examples, a second pattern is provided that may be formed to resist opening of the resealable bag enclosure beyond the end of the zipper assembly 128 when the first side and the second side of the film are pulled apart. In yet another example a gusset may be provided. A heat resistant material 136 may be on either side of the peal seal 130. Plural relief areas 138 may also be provided adjacent the peal seal 130. The relief areas 138 provide additional strain and stress relief for when excess force is applied when opening the zipper assembly 128.

[0016] Figure 2 illustrates an example opening of a resealable bag enclosure 200.

The resealable bag enclosure 200 may include a zipper assembly 201 that may be formed into a film 202. The film 202 and may extend from a first edge 204 to a second edge 206, while the zipper assembly 201 extends form the first edge 204 to point between the first and second edges 204, 206. The zipper assembly 201 may include first and second enclosure elements, opposing teeth, groove and protrusion, interlocking curves, a single closure strip that is sealed by folding back on itself to matte to itself, a single strip of closure that is sealed to the inside of the front panel of a bag enclosure and wraps around the side of the bag enclosure, is gusseted, and attaches to the inside of the back panel of the bag enclosure, etc. Within the film 202, above the zipper assembly 201, may be a peal seal 208 that may have a pattern that is on either side of a film to provide an interlocking connection.

[0017] The peal seal 208 may extend from adjacent the first edge 204 to a stop location 210. In one example, the stop location 210 may be in a middle portion between the first edge 204 and the second edge 206 and adjacent the end of the zipper assembly 201. The peal seal 206 may include a first pattern 212 that may be intermeshing polygon members 214 that extend along a first axis 216 in a first direction. At the stop location 210, a second pattern 218 may be provided that extends along a second axis 220 in a second direction that is different than the first direction. The second pattern may similarly include intermeshing polygon members 222.

[0018] In one example, the first pattern 212 and second pattern 218 extend orthogonal, or perpendicular, to one another. The first pattern 212 and second pattern 218 may including similar patterns, such as both being polygon members, or may be different patterns. In one example, the second pattern 218 at the opening stop location 210 may be formed by multiple intermeshing undulating members that are elongated in a first direction that is different from a second direction in which the zipper assembly is elongated. Alternatively, the second pattern 218 at the opening stop location 210 may be formed by elongated undulating members and intermeshing elongated polygon members, the undulating members and the polygon members elongated in a first direction that is different from a second direction in which the zipper assembly is elongated. By extending in a different direction, a barrier is provided resisting opening of the resealable bag enclosure beyond the end of the zipper assembly 201 when the first side and the second side of the film are pulled apart

[0019] Surrounding the peal seal 206 may be heat resistant material 224. The heat resistant material 224 may be left unsealed to have film to grab hold of to break open the peal seal 206, and keep radiant heat from tacking the film 202 together. The heat resistant material 224 also provides a material for a cut knife to shear against. The heat resistant material 224 may also allow closure of the peal seal 206 and provide heat resistance to keep from applying heat and pressure to the peal seal 206 that may result in deforming of the peal seal 206.

[0020] Plural relief areas 226 may also be provided in the resealable bag enclosure

200. The plural relief areas 226 may be located on the opposite side of the stop location 210 of peal seal 206. In one example, the relief areas 226 may be oval, slits, square, rectangular, or the like. The relief areas 226 may be aligned, side-by-side, extend parallel to the pattern at the stop location 210, etc. Alternatively, instead of an opening, the relief area may be a thinned area in a film that has a thickness that may be less than other surrounding areas. In all, the relief areas 226 provide additional strain and stress relief for when excess force is applied when opening the peal seal 206.

[0021] Figure 3 illustrates a method 300 of manufacturing a resealable bag enclosure. In one example, the method may be used to manufacture the resealable bag enclosure of Figure 1.

[0022] At 302, a first pattern may be formed in a film. The film may be plastic, rubber, ceramic, or the like. The first pattern may be of any type, including intermeshing undulating members, polygons, or the like. The first pattern is provided such that the film may be opened and resealed.

[0023] At 304, a second pattern may be formed in the film. The second pattern may also be of any type, including intermeshing undulating members, polygons, etc. The second pattern may be the same as the first pattern, only extending in a direction that is different than the first pattern. The first and second patterns may be formed at the same time, at different time, in one manufacturing step, in multiple manufacturing steps, etc. In one example, the first pattern may be orthogonal to the second pattern.

[0024] At 306, relief areas are formed in the zipper assembly. The relief areas may include openings, thinned areas compared to other surrounding thicker areas, or the like. When openings are provided, the openings may be slits, ovals, rectangular, square, or the like. The relief areas may be elongated, side-by-side, parallel to one another, spaced equidistant, spaced not equidistant, or the like. In each instance, the relief areas are provided to absorb force to prevent tearing or ripping of the film as a result of opening a peal seal formed by the first pattern. The relief areas may be made at the same time as the first, and/or second pattern, at a different time, during the same manufacturing step or process, or during a different manufacturing step or process, etc.

[0025] At 308, the zipper assembly is formed, or placed into the film, below the first and second patterns. The zipper assembly may be formed at the same time as the first pattern, second pattern, and/or the relief areas, before the forming of the first pattern, second pattern, and/or relief areas, or after the first pattern, second pattern, and/or relief areas. In particular, the first and second enclosures only extend to a mid-point of the film similar to the first and second patterns, that in one example form a peal seal.

[0026] Thus, a bag enclosure and method of making the same is provided. By providing a stop location for a peal seal that has a second pattern that extends in a different direction than the first pattern, tearing or ripping from providing too much force during a cutting or opening process is reduced. Additional relief area may similarly be provided, again to absorb and reduce tearing and ripping from stress.

[0027] In one or more embodiments of the subject matter described herein, a resealable bag enclosure may be provided that includes a film having an opposing first side and second side coupled with each other along opposite first and second edges and a bottom edge that extends between the first and second edges, and a resealable zipper assembly coupled with the first side and the second side of the film. The first side and the second side of the film together may form a pattern at an opening stop location disposed between the first and second edges of the film and adjacent to an end of the zipper assembly. The pattern of the first side and the second side of the film may also resist opening of the resealable bag enclosure beyond the end of the zipper assembly when the first side and the second side of the film are pulled apart. The resealable bag enclosure may also include a peel seal formed between the first side and the second side of the film above the zipper assembly, the first side and the second side of the film forming the pattern in the peel seal with the pattern in the peel seal oriented in a different direction than a pattern of the zipper assembly formed between the first side and the second side at the opening stop location to prevent the peel seal from extending beyond the pattern in the peel seal oriented in a different direction.
