DETAILED DESCRIPTION

Embodiments may be best understood by reference to the drawings, wherein like parts are designated by like numerals throughout. It will be readily understood that the components of the present disclosure, as generally described and illustrated in the drawings herein, could be arranged and designed in a wide variety of different configurations. Thus, the following more detailed description of the embodiments of the apparatus is not intended to limit the scope of the disclosure, but is merely representative of possible embodiments of the disclosure. In some cases, well-known structures, materials, or operations are not shown or described in detail. While the various aspects of the embodiments are presented in drawings, the drawings are not necessarily drawn to scale unless specifically indicated.

FIGS. 1-3 depict an embodiment of a bag 100, according to the present disclosure. More specifically, FIG. 1 is a standard perspective view of the bag 100 in a closed or sealed state; FIG. 2 is a perspective view of the bag 100 of FIG. 1 in an open or unsealed state; and FIG. 3 is another perspective view of the bag 100 of FIG. 1 in an open or unsealed state that depicts a product 172 being removed from the bag 100. The bag 100 can also be referred to as a pouch or other packaging structure.

As shown in FIGS. 1-3, the bag 100 can include a first wall 110, a second wall 120, a third wall 130, and a fourth wall 140. The bag 100 can also include a fifth wall 150, and can be configured as a flat bottom bag. The bag 100 can also be configured as a quad-seal bag, a vertical machine bag, or any other suitable type of bag. In some embodiments, the first and second walls 110, 120 may also be referred to as front and rear walls, respectively. When used, directional terms, such as “front,” “rear,” “bottom,” etc., are used with respect to the orientation shown in the corresponding figure. The terms are used for the sake of convenience and are not necessarily intended to be limiting. For example, the front wall could in fact be printed with material that is more suitable for a rear wall of a packaging (e.g., printed with nutritional information), such that the front wall in fact serves as a rear wall. In some embodiments, the third wall 130 and the fourth wall 140 can be referred to as first and second gussets, respectively. In other embodiments, the third wall 130 and the fourth wall 140 can be referred to as first and second sidewalls, respectively. The fifth wall 150 may also be referred to herein as the bottom wall or base.

Additionally, although FIGS. 1-3 primarily depict the first wall 110 and third wall 130, it will be appreciated that the second wall 120 and fourth wall 140 can include the same or similar features. For example, the fourth wall 140 may be the same as, or substantially the same as, the third wall 130. The second wall 120 may also be the same as, or substantially the same as, the first wall 110, except that the second wall 120 does not include an opening 190 and associated elements (e.g., label 160). As such, the discussion herein regarding many features of the first wall 110 and the third wall 130 is equally applicable to the second wall 120 and fourth 140, even though the features may not be specifically depicted.

With continued reference to FIGS. 1-3, the first wall 110, second wall 120, third wall 130, fourth wall 140, and fifth wall 150 can cooperate to define a cavity 170 in the interior of the bag 100. The cavity 170 may receive and retain a one or more products 172, as shown in FIGS. 1-3 where the individual products 172 are shown in phantom. At the user's discretion, the products 172 may be removed from the cavity 170 through an opening 190, as shown in FIG. 3.

Any suitable variety of products 172 may be retained within the cavity 170 of the bag 100. For example, the product 172 can comprise a food product, including but not limited to, cheese, crackers, cookies, snack bars, etc. In various embodiments, the bag 100 can be used advantageously to contain individually wrapped products 172. In some embodiments, the bag 100 is composed of a material suitable to act as a barrier layer to preserve the products 172 retained within the cavity 170. In others, such as those in which the products 172 are individually-wrapped, the bag 100 may be composed of a material that does not serve as a barrier layer.

In some embodiments, the product 172 comprises a beverage or canned food product. In such embodiments, the product 172 can be contained within a container. One or more containers may then be retained within the cavity 170 of the bag 100. Non-food products 172 can also be retained within the cavity 170 of the bag 100. For example, individually packaged non-food products can be retained within the cavity 170 of the bag 100. Containers containing non-food products can also be retained within the cavity 170 of the bag 100.

In some embodiments, the bag 100 may be described as being a gravity fed bag 100. For example, at a user's discretion, one or more products 172 may be withdrawn from the opening 190 of the bag 100. The remaining products 172, while still retained within the bag 100, may then move downward in response to gravitational forces (i.e., gravity). A user may thereafter remove one or more additional products 172 from the opening 190 of the bag 100 at their discretion. As can be appreciated, the products 172 may be retained within the bag 100 and kept from spilling out absent removal by a user.

The bag 100 may also be configured for easy access or ready snacking. In some embodiments, the contents (e.g., products 172, etc.) of the bag 100 may be accessed through the opening 190, for example, using a single hand when the bag 100 is resting on a surface (e.g., a shelf), or, as another example, one hand may be used merely to hold the bag 100 (e.g., at an upper portion 102 of the bag 100) while another hand is used to access the contents of the bag 100 through the opening 190.

In some embodiments, the bag 100 can be configured to stand upright. In other words, the bag 100 may be capable of standing on its own. The bag 100 may also be substantially capable of maintaining its structural conformation. As shown in FIGS. 1-3, the fifth wall 150 can serve as a base on which the bag 100 rests. The first wall 110, second wall 120, third wall 130, and fourth wall 140 extend upwardly from the fifth wall 150. The first wall 110, second wall 120, third wall 130, and fourth wall 140 can also be attached or otherwise directly coupled to the fifth wall 150. In other embodiments, one or more of the first wall 110, second wall 120, third wall 130, and fourth wall 140 may be integrally formed with the fifth wall 150.

In some embodiments, the first wall 110, second wall 120, third wall 130, and fourth wall 140 can be attached to the fifth wall 150 via one or more seams 182, 184, 186, 188. The seams 182, 184, 186, 188 can be formed by attaching or otherwise coupling the inner surfaces of two adjacent ends of the walls and/or gussets. The seams 182, 184, 186, 188 can protrude or otherwise extend outwardly and can provide increased stabilization to the bag 100. For example, the seams 182, 184, 186, 188 may assist in keeping the bag 100 from tipping over.

In the illustrated embodiment, the seams 182, 184, 186, 188 extend along the various ends or edges of the fifth wall 150, which serves as the base of the bag 100. For example, one seam 182 extends along the lower end 114 of the first wall 110 and couples the first wall 110 to the first end 152 of the fifth wall 150. Another seam 184 extends along the lower end 124 of the second wall 120 and couples the second wall 120 to the second end 154 of the fifth wall 150. Other seams 186, 188 extend along the lower ends 134, 144 of the third and fourth walls 130, 140 and couple the third and fourth walls 130, 140 to the third and fourth ends (or first and second side ends) 156, 158 of the fifth wall 150 in similar fashion.

In some embodiments, the arrangement of the seams 182, 184, 186, 188 may be such that the seams 182, 184, 186, 188 are relatively continuous around the base or fifth wall 150 of the bag 100. In other embodiments, the seams 182, 184, 186, 188 can extend only along one or more portions of the base or fifth wall 150 of the bag 100.

The bag 100 can also include an upper seam 180 that extends along an upper portion 102 of the bag 100. The upper seam 180 may extend along an upper end 112, 122 of the first and second walls 110, 120. As shown in FIG. 1, the upper seam 180 may also extend along the upper portion 102 of the bag 100 at a distance that is below the upper ends 112, 122 of the first and second walls 110, 120. The upper seam 180 can be used to attach or otherwise directly couple the first wall 110 to the second wall 120, as shown in FIGS. 1-3. In some embodiments, the upper seam 180 can also include a handle (such as the upper seam 880 and handle 811 shown in FIGS. 10-12). The upper seam 180 may also provide added stabilization and structural integrity to the bag 100. Other seams may also be used (such as the lateral seams 681 shown in FIGS. 6-7) to provide additional stabilization, relative rigidity, and/or structural integrity to the bag 100 as desired. In yet other embodiments, the bag 100 may be devoid of protruding seams (such as the bag 700 depicted in FIGS. 8-9).

The seams disclosed herein can be formed in various ways, and any suitable variety of seams may be used. In some embodiments, the seams include seals, such as heat seals. The seals can be configured to close (e.g., in an airtight, liquid-tight, and/or hermetic fashion) the bag 100. Any suitable variety of seals may be used. For example, in some embodiments, the seals comprise heat seals. In other embodiments, the seals may be formed via adhesive, ultrasonic welding or any other suitable method.

The strength of the seams and/or seals may be varied as desired. For example, the amount of energy imparted when forming a seal can determine whether the seal will be a peel seal that can be readily opened or a lock seal that is much stronger and much more difficult, or even impossible to open, without damaging the bag 100. In various embodiments, the seams (e.g., 180, 182, 184, 186, 188) comprise lock seals such that the products 172 are only intended to be removed through the opening 190 on the first wall 110. For example, once the cavity 170 of the bag 100 has been filled with a product 172, the upper seam 180 can be formed as a lock seal to close the upper portion of bag 100, after which the products 172 may only be intended to be removed through the opening 190 disposed on the first wall 110. In other embodiments, the upper seam 180 may comprise a peelable seal that can be readily opened, and the product 172 can be removed from the bag 100 either from the opening 190 in the first wall 110 or by the opening created by separating the upper seam 180.

With continued reference to FIGS. 1-3, it will be appreciated that the third and fourth walls 130, 140 may serve various functions. For example, the third and fourth walls 130, 140 can comprise a folded piece of material that is capable of transitioning from a flattened state to an expanded state. The third and fourth walls 130, 140 can also be configured to permit portions of the first and second walls 110, 120 to be spaced apart from each other as shown in the configuration depicted in FIGS. 1-3.

The third and fourth walls 130, 140 may also provide structural integrity to the bag 100. For example, as depicted in FIGS. 1-3, the third and fourth walls 130, 140 extend from the first wall 110 and the second wall 120. Stated otherwise, the third and fourth walls 130, 140 can be attached or otherwise directly coupled with each of the first and second walls 110, 120. The attachment of the third and fourth walls 130, 140 to the first and second walls 110, 120 may provide relative rigidity and assist in maintaining the structural integrity of the bag 100. Further, as shown in FIGS. 6-7 and discussed below, in some embodiments, lateral seams may be formed along the lateral ends of the first and second walls 110, 120 and the lateral ends of the third and fourth walls 130, 140 if desired.

As shown in FIGS. 1-3, the bag 100 also includes an opening 190. The opening 190 can be disposed along a lower portion 104 of the first wall 110 of the bag 100. In other embodiments, the opening 190 can be disposed along a portion of the second wall 120, the third wall 130, or the fourth wall 140. The opening 190 can also be disposed at various locations along the first wall 110, second wall 120, third wall 130, or fourth wall 140. For example, the opening 190 can be disposed along a lower portion 104, as shown in FIGS. 1-3. The opening 190 can also be disposed along a middle portion or an upper portion if desired. Further, the opening 190 can extend longitudinally, vertically, or at an angle (e.g., diagonally between longitudinal and vertical planes of the bag 100).

When the bag 100 is in the closed or sealed state as shown in FIG. 1, the opening 190 may be blocked, or otherwise closed, and access to the inner cavity 170 of the bag 100 may be denied or otherwise restricted. For example, a label 160 can be used to cover the opening 190 and deny access to the inner cavity 170 of the bag 100. In other embodiments, a flap may be used to cover the opening 190 (such as the flap 664 shown in FIGS. 6-7). In yet other embodiments, a tear-away strip of material may cover the opening 190 (such as the tear-away strip 793 of FIG. 8).

In the illustrated embodiment of FIG. 1, a label 160 is disposed over the opening 190. The label 160 can be adhesively attached or coupled to the first wall 110 of the bag 100. The label 160 can also be peelable and/or removable. For example, the label 160 can be partially, or completely, removed from the bag 100 as indicated by the reference arrow.

In some embodiments, the label 160 can include one or more pull tabs 162. The pull tabs 162 can be gripped by a user to assist in peeling or otherwise removing the label 160 from the bag 100. For example, a user may grasp the pull tab 162 and pull the label 160 away from the first wall 110 in the direction of the reference arrow to remove the label 160.

In some embodiments, the label 160 is non-resealable. In other words, the label 160 is intended to be removed from the bag 100 and discarded. In other embodiments, the label 160 can be resealable, and can be re-attached onto the first wall 110 of the bag at the discretion of the user. For example, the label 160 may comprise a resealable adhesive. The resealable adhesive can be disposed on a surface of the label 160 and/or an outer surface of the bag 100 (e.g., the first wall 110). A user may remove the label 160 to gain access to the products 172 within the bag 100. The user may thereafter place the label 160 back over the opening 190 and reseal the label 160 onto the first wall 110. Illustrative resealable adhesives that may be used include velcro adhesives (e.g., hook and loop fasteners and/or hook and hook fasteners), acrylic adhesives, polyurethane adhesives, hot melt adhesives, low tack adhesives, etc. Other types of resealable adhesives known to one skilled in the art can also be used.

In some embodiments, the opening 190 is formed by removing material from the first wall 110 during the manufacturing of the bag 100. For example, the opening 190 can be die cut out of the first wall 110. The opening 190 can also be laser perforated or scored and removed from the first wall 110. The opening 190 can also be cut with a blade. In other embodiments, material is not removed from the first wall 110 during the manufacturing of the bag 100 to form the opening 190. Rather, tear lines may be formed on the first wall 110 such that a segment of material from the first wall 110 may be torn, partially removed, or completely removed by a user when the bag 100 is initially opened. The tear lines can comprise one or more perforated lines. The tear lines can be die cut, laser perforated or scored, cut with a blade, or formed by other suitable methods.

In some embodiments, tear lines can be formed on the first wall 110 to define an opening region and a label 160 (or flap, etc.) can be placed over the tear lines and opening region. The label 160 (or flap, etc.) can also be coupled to or adhesively attached to the segment of material within the tear lines. As the label 160 (or flap, etc.) is removed, the segment of material from the first wall 110 that is coupled to or adhesively attached to the label 160 (or flap, etc.) may be torn along the tear line and removed from the first wall 110 thereby forming the opening 190. In yet other embodiments, the opening 190 may be opened and closed with a zipper seal.

As shown in FIGS. 2-3, when the bag 100 is in the open or unsealed state, the opening 190 provides access to the inner cavity 170 of the bag 100. For example, a user may extend at least a portion of a hand or hands into the opening 190 to access a product 172 which may thereafter be removed from, or otherwise pulled out of, the bag 100. As such, the opening 190 can be sized and/or shaped to provide adequate clearance for at least a part of a hand of a user to extend into the cavity 170 of the bag 100. In others, the opening 190 is sized to allow the product 172 to be shaken from the bag without being retrieved by a user's hand. As can be appreciated, however, the size and/or shape of the opening 190 can vary as desired. For example, the size and/or shape of the opening 190 can vary depending on the size and/or shape of the food product 172 that is contained in the bag 100. In some embodiments, for example, the opening 190 is substantially rectangular in shape. In other embodiments, the opening is substantially oval in shape. In some embodiments, the opening 190 extends longitudinally across the majority of the first wall 110. In other embodiments, the opening 190 extends longitudinally across only a portion of the first wall 110. Other shapes and/or sizes of openings 190 are also contemplated.

Any variety of materials may be used to form the bag 100. For example, in some instances, it can be desirable to select materials that are relatively stiff such that the bag 100 is sufficiently rigid to hold or maintain its structure or conformation. It may also be desirous to form a bag 100 that is relative flexible.

In some embodiments, the bag 100 comprises a single-layer film. In other embodiments, the bag 100 comprises a multi-layer film. In some embodiments, the film comprises one or more plastic and/or other polymeric materials. The bag 100 may also comprise a laminate or a coextruded material. In some embodiments, the bag 100 comprises a heat sealable material. Exemplary materials that may be used in forming the bag 100 include polyethylene polymers and copolymers, polypropylene polymers and copolymers, polyester polymers and copolymers, and/or polyamide polymers and copolymers. In some embodiments, the bag 100 may include paper and/or cardboard materials alone or in combination with films, laminates or coextruded materials. In other embodiments, the bag 100 does not include paper and/or cardboard materials. In some embodiments, the bag 100 includes polylactic acid (PLA). In yet further embodiments, the bag 100 includes cellulose materials such as cellophane. Other materials known to one of skill in the art can also be used.

If desired, the bag 100 can also include printed indicia 174 of any suitable variety. The printed indicia 174 may be disposed on any portion of the bag 100, such as the first wall 110, second wall 120, third wall 130, fourth wall 140 and/or fifth wall 150.

As previously mentioned, the shape and/or size of the opening 190 may vary as desired. Illustrative openings 290, 390, 490, 590, are depicted in FIG. 4 and FIGS. 5A-5C. FIG. 4 is a plan view of an embodiment of a bag 200 that depicts the opening 290 on a first wall 210 of the bag 200. FIGS. 5A-5C are partial plan views of several embodiments of bags 300, 400, 500 that depict variations in the opening 390, 490, 590 on the first wall 310, 410, 510 of the bags 300, 400, 500.

As shown in FIG. 4 and FIGS. 5A-5C, the opening 290, 390, 490, 590 may include an elongated portion 292, 392, 492, 592 that extends along the lower portion 204, 304, 404, 504 of the bags 200, 300, 400, 500. Additional material may also be removed from the first wall 210, 310, 410, 510 to make the opening 290, 390, 490, 590 more user friendly. For example, in FIG. 4, additional material has been removed from the first wall 210 near the center region 294 of the opening 290 such that the center portion of the opening 290 may open wider when a user inserts a hand. In FIGS. 5B and 5C, additional material has been removed from the first wall 410, 510 near the end regions 496, 497, 596, 597 of the opening 490, 590 such that the opening 490, 590 may open wider when a user inserts their hand. Other shapes and/or sizes of openings 290, 390, 490, 590 may also be used.

FIGS. 6 and 7 depict another embodiment of a bag 600 that can resemble the bag 100 described above in certain respects. Accordingly, like features are designated with like reference numerals, with the leading digits incremented to “6.” Relevant disclosure set forth above regarding similarly identified features thus may not be repeated hereafter. Moreover, specific features of the bag 600 may not be shown or identified by a reference numeral in the drawings or specifically discussed in the written description that follows. However, such features may clearly be the same, or substantially the same, as features depicted in other embodiments and/or described with respect to such embodiments. Accordingly, the relevant descriptions of such features apply equally to the features of the bag 600. Any suitable combination of the features and variations of the same described with respect to the bag 100 can be employed with the bag 600, and vice versa. This pattern of disclosure applies equally to further embodiments depicted in subsequent figures and described hereafter, wherein the leading digits may be further incremented.

As shown in FIGS. 6 and 7, in some embodiments, the bag 600 includes lateral seams 681 that may be used to attach the lateral ends 616, 618, 626, 628 of the first and second walls 610, 620, and the lateral ends 636, 638, 646, 648 of the third and fourth walls 630, 640. More specifically, a first lateral end 616 of the first wall 610 is attached to the first lateral end 636 of the third wall 630 to form lateral seam 681a; a second lateral end 618 of the first wall 610 is attached to the first lateral end 646 of the fourth wall 640 to form lateral seam 681b; a first lateral end 626 of the second wall 620 is attached to the second lateral end 638 of the third wall 630 to form lateral seam 681c; and a second lateral end 628 of the second wall 620 is attached to the second lateral end 648 of the fourth wall 640 to form lateral seam 681d. As previously discussed, the seams 681 can be formed by attaching the inner surfaces of the walls 610, 620, 630, 640.

In some embodiments, the lateral seams 681 can include seals (e.g., heat seals), and may provide added stability to the bag 600. Additionally, the lateral seams 681 can include lock seals that extend along each of the lateral edges of the bag 600. As previously discussed, lock seals can be difficult to open, and are often intended to remain closed.

As further shown in FIGS. 6 and 7, an upper seam 680 is disposed at the upper end of the bag 600. More specifically, the upper seam 680 attaches the upper end 612 of the first wall 610 to the upper end 622 of the second wall 620. As previously discussed, the upper seam 680 can be a lock seal, or a peelable seal, depending on the desired configuration of the bag 600.

In the illustrated embodiment, the bag 600 also includes a flap 664. In some embodiments, the flap 664 is resealably attached to the first wall 610. The flap 664 can be configured to open and close to allow or deny access to the contents of the bag 600. For example, in the closed state depicted in FIG. 6, the flap 664 can be coupled to or adhered to the first wall 610 of the bag 600. The flap 664 also covers the opening 690 of the bag 600 thereby denying access to the contents of the bag 600.

In the open state depicted in FIG. 7, the flap 664 has been opened and access to the contents of the bag 600 is allowed. In the open state, a portion 665 of the flap 664 remains coupled to or adhered to the first wall 610 of the bag 600. In the illustrated embodiment, the portion 665 of the flap 664 that remains coupled to or adhered is attached to the first wall 610 at a position that is lower than or otherwise below the opening 690, and the flap 664 is opened substantially downward. As indicated by the reference arrow, the flap 664 may opened and closed at the discretion of the user. In other embodiments, the portion 665 of the flap 664 that remains coupled to or adhered can be attached to the first wall 610 at a position that is above the opening 690, and the flap 664 can open substantially upwards. Similarly, the portion 665 of the flap 664 that remains coupled to or adhered can also be attached to the first wall 610 on either side of the opening 690.

The flap 664 can include a pull tab 662 to aid the user in opening and/or closing the flap 664. The flap 664 can also include an adhesive region 666 disposed on an inner surface 668 of the flap 664.
