A storage bag includes a first sidewall and a second sidewall connected to the first sidewall so as to form an interior of the bag with an opening to the interior. The storage bag also includes at least one zipper profile provided adjacent to the opening to the interior of the bag. The at least one zipper profile has opposing closure elements that respectively interlock with each other. The storage bag also includes a slider with at least one opening member and at least one detent on at least one end of the bag. The at least one detent is configured to engage with the at least one opening member of the slider to provide a leak-proof end seal.

A reclosable bag includes a container configured to retain one or more items. The container includes a front panel coupled to a rear panel at a first side and a second side. A zipper is coupled to the front panel and the rear panel. The zipper is separated from the first side by a first gap, and the zipper is separated from the second side by a second gap. One or more side seals are between the first side and at least a first portion of the zipper and the second side and at least a second portion of the zipper.

One or more side seals are between the first side and at least a first portion of the zipper and the second side and at least a second portion of the zipper.

A zipper for a reclosable bag includes a first interlocking element, and a second interlocking element. The first interlocking element and the second interlocking element are configured to cooperate to selectively open and close the zipper. One or both of the first interlocking element and the second interlocking element are formed of at least 85% repulpable material.

Disclosed are flexible fluid reservoirs including a front sheet and a back sheet, each comprising a four-layer insulated wall. The four-layer insulated wall includes an interior layer and an exterior layer, and a metallic film layer and an insulation layer disposed between the interior layer and the exterior layer where the metallic film layer is oriented toward the exterior layer and the insulation layer is oriented toward the interior layer. One or more of the interior or exterior layers can be a metallocene modified polyethylene film. The metallic film layer can be aluminum coated polyethylene terephthalate resin. The insulation layer can be a foam layer comprising closed cell polyethylene resin. The four-layer insulated wall can resist or limit temperature changes of a fluid disposed within the reservoir for a period of time. The insulated fluid reservoirs can include closure mechanisms for sealing an upper opening of the reservoir.

A storage bag has a first closure profile attached to a first side surface, with the first closure profile forming a lip between an interlocking member and an edge of the first closure profile. The bag also includes a second closure profile attached to the second side surface, with the second closure profile forming a lip between an interlocking member and an edge of the second closure profile. The lips of the first and second closure profiles are visually distinct colors or different shades of a color in order to aid the user in locating the lips.

A protective sleeve is disclosed herein consisting of a rectangular upper and lower panel with three edges of the panels permanently sealed together and at least one shorter edge unsealed to allow for full insertion and extraction by one person a swimming pool cover hold-down weight water tube and allows for airtight or non-airtight sealing of the unsealed end.

A device for accepting parcels and deliveries, having: (a) a zipper bag; (b) a one-way toothed round bar mounted to the puller of the zipper; (c) a pawl component configured to make the one-way toothed round bar to move one-way along its axial direction; and (d) a fixing base mounted to the zipper bag near the top stop of the zipper. The pawl component is fixed in the fixing base, and the one-way toothed round bar can only move inwards into the fixing base if a lock passes through the fixing base's locking hole. Otherwise, the pawl component is removable, and the one-way toothed round bar can be pulled back. The position of the fixing base satisfies: the zipper bag is closed completely when the one-way toothed round bar entirely enters into the fixing base. Also provided a similar device based on a tie-able bag.

There is provided a zipper tape bonded to a bag body having a first surface and a second surface and including: a zipper tape body including a first base strip bonded to the first surface, a second base strip bonded to the first surface with a bonding portion, and engagement portions being mutually engageable and projecting from the first and second base strips, respectively; and a cutting strip provided in a region where the second base strip faces the first surface and does not face the first base strip. The zipper tape body is formed of a resin composition whose main component is a polyolefin resin. The cutting strip is formed of a resin composition whose main component is a polyolefin resin and includes a cutting strip body and a peelable layer layered on the cutting strip body and formed of a resin composition having peelability to a polyolefin resin.
