The container or pouch (40) is made entirely of elastomer and comprises a body (42) having a front wall (46) and a rear wall (48) connected to the front wall (46) along the peripheral edge (50), a front side (70) having a front sealing profile (84) having a male closing element (100), and a rear side (72) having a rear sealing profile (86) having a female closing element (102) and a cavity (156), and a centerline (162) extends through the cavity (156). The rear side (72) includes an inner part (180) including the entire cavity (156) and an outer part (182). The thickness (224) of the thickened area (208) measured in a direction parallel to the centerline (162) is less than 35% of the total thickness (234) of the closed system (44) in the closed shape measured in a direction parallel to the centerline (162).

Description

A closing system for pouches or containers Cross-reference regarding related applications This application claims priority to U.S. application no. 17/351,904, titled “Closure System for Pouch or Container,” filed on June 18, 2021, the entire contents of which are incorporated by reference in the whole. References regarding federally sponsored research or development Not applicable sequential list Not applicable Technology field The present disclosure relates to pouches or containers in general comprising an improved closing system, and more particularly to closing systems comprising improved sealing members and/or cool-touch tabs. Historically, resealable pouches and containers used in food packaging (collectively "bags") comprise a folded web of elastomer material, or a web formed from blown, cast, monolayer, or co-extruded films, and have two side walls that are folded at the bottom and sealed at the sides. Bags typically have a resealable fastener or closure system at the top of the bag, such as an adhesive, wire tie, or plastic zipper. While thermoplastic bags possess various advantages including reduced cost, ease of manufacturing, efficient packaging and transport, and desirable sealing capabilities for end use, these bags are typically not reusable. Given consumer trends regarding reusable packaging, it is desirable for new and improved food packaging bags to retain the advantages associated with bags of the prior art. Therefore, it is desirable to retain or enhance the advantages of bags of the prior art through the use of materials that provide repeated use, that is, by using one or more sustainable materials. Reusable and sealable bags are known in the art. For example, elastomer pouches having longitudinally applied resealable closing mechanisms across the opening of the elastomer pouch that allow for repeated opening and closing of the pouch known in the art. One specific example of a known reusable bag is described in U.S. Patent No. 9,371,153, which describes elastomer containers with integrated leak-resistant seals. While elastomer bags are becoming more desirable due to consumer demand for reusable bags, these types of bags possess physical properties different from conventional thermoplastic bags, which require different sealing mechanisms and considerations. Although technologies related to the sealing mechanisms of conventional thermoplastic bags have been developed for at least the past 70 years, technologies for sealing thermoplastic bags are not directly transferable to the requirements of elastomer bags. This is because some elastomer bags may be used during cooking and may be exposed to extreme temperatures and pressures, and/or are required to handle various forces on the bag walls that are not typically considered thermoplastic bags. Improvements have been made by referencing conventional sealing systems to provide enhanced seals; however, these seals generally involve complex structures, which can lead to increased complexity when manufacturing and using such sealing systems. These sealing structures may include interlocking closure profiles across multiple pairs, which can be difficult to seal and/or cause user confusion regarding whether the multiple pairs of interlocking closure profiles have been properly sealed. Seals of this type used for thermoplastic bags are impractical or cannot be directly converted into seals for reusable elastomer bags. Therefore, it is desirable to provide a re-closable closure mechanism for elastomer pouches that includes a simpler sealing structure capable of providing hermetic or watertight seals and can be used in more stringent applications. Furthermore, conventional bags formed from both elastomer and thermoplastic materials typically do not include additional structures that allow a user to hold the bag, except directly along and over the sealing structure. In particular, when the bag is filled with warm or hot contents, the user cannot hold the bag along the side walls, and there are no spaces for the user to grasp the bag other than the corners. Some conventional containers include extensions that allow the user to grasp a separate component when holding the bag, but these designs are not ergonomic, and the extensions do not provide the user with an easily identifiable signal that they are intended to be grasped when holding a bag containing warm or hot contents. Therefore, there is a need for reusable pouches or containers that alleviate one or more of the problems associated with or specific to existing containers and pouches. The present disclosure provides an enhanced closing system comprising a sealing structure that allows for quick and easy sealing and opening, and/or cool-touch tabs that allow a user to grasp the bag at a desired position along the closing system. In some embodiments, the container or pouch is made entirely of elastomer and comprises a closing system comprising a body including a front wall and a rear wall connected
