RESEALABLE STORAGE BAG AND ASSOCIATED COMPONENTS

Abstract

A resealable storage bag features a dual-rib zipper profile in which two bulb-tipped male ribs on one wall lock into matching rounded grooves on the opposite wall, creating a robust airtight seal. An exterior slider with ergonomic pinch zones and a stepped, multi-slot channel guides the ribs into the grooves, allowing the seal to be achieved in a single pass even when the closure elements use softer resin blends. A hinged flap anchored to one wall carries at least part of the zipper profile and pivots between parallel and perpendicular positions. When the bag is stressed from below, the flap rotates to an orthogonal attitude that resists separation yet remains easy to open from above. A one-way valve enables vacuum evacuation for compact storage, while optimized divider lengths, ramp radii and slot clearances within the slider further enhance sealing reliability.

Illustrated Embodiments

[0049] Now turning to the drawings, FIG. 1A-1B shows a rescalable storage bag (100). The rescalable storage bag comprises two opposing bag walls being a first wall (101) and a second wall (104). The first and second walls form an opening end (107) where items can enter and exit from and are coupled at a sealed end (111). The first wall comprises a first internal side (102) and a first external side (103) opposite the first internal side. Likewise, the second wall comprises a second internal side (105) and a second external side (106) opposite the second internal side. A valve (108) is disposed on the first wall to evacuate air from an interior of the resealable storage bag. The resealable storage bag further comprises a zipper profile (200) disposed in the interior of the rescalable storage bag at an upper end (109) for sealing the opening end. The zipper profile comprises a first closure mechanism (201) coupled to the first internal side and a second closure mechanism (207) coupled to the second internal side. A zipper slider (300) is coupled to both the first and second external sides and is configured to aid in the first closure mechanism mating with the second closure mechanism to create an air tight seal.

[0050] FIG. 2A-2B shows a cross-section view of a zipper profile (200) of a rescalable storage bag (100) in accordance with a first illustrated embodiment. The zipper profile comprises a first closure mechanism (201) coupled to a first internal side (102) and a second closure mechanism (207) coupled to a second internal side (105). The first closure mechanism comprises a first pair of closure elements (202) being a pair of male elements. The pair of male elements comprises a first rib (204) and a second rib (205) extending parallel to the first rib at an upper end of the rescalable storage bag. The first rib and the second rib each comprise a bulbous tip (206) for engagement with the second closure mechanism. The second closure mechanism comprises a second pair of closure elements (208) extending parallel along the upper end of the rescalable storage bag at the second internal side. The second pair of closure elements further comprises a pair of female elements (209) being a first groove (210) and a second groove (211). Each of the first groove and the second groove comprises a rounded groove for receiving the bulbous tip of the first rib and second rib, respectively. The first rib and the first groove are positioned a first distance from the opening end such that the first rib is configured to engage with the first groove. Additionally, the second rib and the second groove are positioned a second distance from the opening end such that the second rib is configured to engage with the second groove.

[0051] FIG. 2A includes exemplary dimensions and spacing of the zipper profile (200). As shown, the center of the first pair of closure elements (202) and the second pair of closure elements (208) are each spaced about 0.310 to 0.320 apart.

[0052] The first closure mechanism (201) is shown as comprising a pair of male elements (203) disposed on the first internal side (102) and the second closure mechanism (207) is shown as comprising a pair of female elements (209) disposed on the second internal side (105). Other configurations of the zipper profile can also be utilized as can be appreciated by one having skill in the art. For example, the pair of female elements may be disposed on the first internal side and the pair of male elements are disposed on the second internal side. In addition to or alternatively, the first closure mechanism may comprise one male element and one female clement, and the second closure mechanism may comprise a corresponding female element and male element. In other embodiments, the first and second closure mechanisms may comprise three or more rows of closure elements.

[0053] FIG. 3A-3C show a rescalable storage bag (100) with a hinged flap (213) in accordance with a second illustrated embodiment. The rescalable storage bag comprises two opposing bag walls being a first wall (101) and a second wall (104). The first wall and the second wall form an interior (110) of the rescalable storage bag accessible by an opening end (107). At an upper end (109) of both the first wall and the second wall is a zipper profile (200). The zipper profile comprises a first closure mechanism (201) and a second closure mechanism (207) both disposed at the interior of the rescalable storage bag. The first closure mechanism is coupled to a hinged flap. The hinged flap extends from an attached end (214) to a detached end (215). The attached end of the hinged flap is coupled to a first internal side of the first wall. The detached end and the first closure mechanism are configurable to rotate about the first wall such that the hinged flap can be parallel or orthogonal to the first wall in addition to other positional relationships. Generally, the attached end is positioned closer to the opening end than the detached end.

[0054] The second closure mechanism (207) is coupled to a second internal side (105) of the second wall (104) wherein the second closure mechanism is in a fixed state relative to the second wall. The coupling of the second closure mechanism can be direct or indirect. Direct coupling includes the second closure mechanism having a second pair of closure elements (208) attached to the surface of the second internal side. Indirect coupling includes the second pair of closure elements coupled to an intermediary thermoplastic layer and the intermediary thermoplastic layer is coupled to the surface of the second internal side.

[0055] The hinged flap (213) increases strength of the zipper profile (200) when force is applied below the first and second closure mechanisms (201; 207). When the first wall (101) and the second wall (104) are pulled apart below the sealed zipper profile, the hinged flap causes the first closure mechanism to rotate into a substantially orthogonal position with at least one of the first and second walls. In some embodiments, the second closure mechanism may similarly rotate into a substantially orthogonal position due to the second closure mechanism's engagement with the first closure mechanism. The orthogonal configuration requires substantially more force to break the zipper profile seal compared to a conventional parallel configuration with the first and second walls due to direction of the zipper profile coupling no longer being in alignment with the outward force being applied below the zipper profile. This increased resistance created by the hinged flap is not present when the first and second walls are separated above the zipper profile due to the hinged flap being unable to rotate. This allows case of opening the rescalable storage bag (100) above the zipper profile while resisting expansion of the bag walls below the zipper profile. Scenarios can include when the rescalable storage bag is overfilled and the contents within the rescalable storage bag press against the first and second bag walls below the zipper profile.

[0056] FIG. 4-9 show a zipper slider (300) in accordance with a third illustrated embodiment. The zipper slider is configured to attach to a rescalable storage bag (FIG. 1A; 100) at an opening end (FIG. 1B; 107) thereof and aid in sealing a zipper profile (FIG. 2A; 200). The zipper slider comprises a slider body (301) extending from a top surface (302) to a bottom surface (303) wherein the top surface is disposed over the opening end of the resealable storage bag when the zipper slider is engaged therewith. The zipper slider further comprises a proximal pinching surface (304), a distal pinching surface (305), a first side surface (307), and a second side surface (308). The proximal pinching surface and the distal pinching surface each comprise a concave exterior (306) to provide ergonomic contact when a user grips the zipper slider. A slider channel (320) extends from the first side surface to the second surface. The slider channel further extends from the bottom surface toward the top surface.

[0057] The slider channel (320) comprises a tapered opening (321) at the bottom surface (303) of the slider body (301) to assist a user with coupling the zipper slider (200) onto the rescalable storage bag (FIG. 1A; 100). The zipper slider includes a first guide slot (328), a second guide slot (337), and a header pocket (322). The first guide slot is configured to surround bottommost elements of a first closure mechanism (FIG. 2A; 201) and a second closure mechanism (FIG. 2A; 207) of the zipper profile. The second guide slot is configured to surround uppermost elements of the first closure mechanism and the second closure mechanism. The header pocket is configured to surround a top edge of the rescalable storage bag disposed above the zipper profile. The zipper slider comprises a symmetrical profile when viewed from one of the first side surface or the second side surface. For purposes of clarity, when features on one side on the first guide slot and second guide slot are described, a corresponding mirror image of said feature is also implicitly disclosed.

[0058] The first guide slot (328) is flanked by a first divider (323) and a second divider (331). The first divider is formed by a first plateau (326) disposed on either side of the first divider. The first divider further comprises a first top ramp (325) slanting downward from the first plateau to a first slot side (329) of the first guide slot. The second divider is formed by a second plateau (335) disposed on either side of the second divider. The second divider further comprises a second bottom ramp (333) and a second top ramp (334) disposed on opposite ends of each second plateau. The second bottom ramp slants downward from the second plateau to the first slot side. The second top ramp slants downward from the second plateau to a second slot side (338) of the second guide slot (337). Each of the first and second slot sides are substantially linear compared to the top and bottom ramps of the first and second dividers.

[0059] The second guide slot (337) is flanked by the second divider (331) and a third divider (340). The third divider is formed by a third plateau (343) disposed on either side of the third divider. The third divider further comprises a third bottom ramp (342) slanting downwards from each third plateau towards the second slot side (338) of the second guide.

[0060] The zipper slider (300) is optimized to seal a zipper profile having a blended resin that creates a softer and more conforming relationship between male and female elements. Particular dimensions and radius curvature of the zipper slider improves the zipper slider's ability to seal the zipper profile with a single pass of the zipper slider. The preferable dimensions disclosed herein assists the male elements having a bulbous tip to fill in and conform with a rounded groove of the female elements. In one embodiment, the first divider (323) comprises a first divider length (324) between 0.025 and 0.172. The second divider (331) comprises a second divider length (332) between 0.144 and 0.186. The third divider (340) comprises a third divider length (341) between 0.080 and 0.102. Each first slot side (329) comprises a first slot length (330) between 0.074 and 0.136 and forms a gap around 0.064, Each second slot side (338) comprises a second slot length (339) between 0.085 and 0.170 and forms a gap around 0.066. The first top ramp (325) comprises a curvature radius between 0.010 and 0.100. The second bottom ramp (333) comprises a curvature radius between 0.040 and 0.080. The second top ramp (334) comprises a curvature radius between 0.001 and 0.041. The third bottom ramp (342) comprises a curvature radius between 0.001 and 0.041.
