Abstract: A container system that includes a container element with a hole or series of holes that are sealed by at least one seal assembly with at least one seal element. When the container system is placed into material to be captured, the seal element of the seal assembly is displaced from the holes when material exerts inward pressure on the seals, allowing the container system to self-fill with material. Once the desired amount of material is captured, the container system is removed and captured material exerts outward pressure on the seal assembly, causing the seal element to close the holes and the container system to self-seal.

Abstract: The present invention provides a multi-purpose container configured to retain granulate material for short- or long-term use. Furthermore, the present invention will provide various rates of flow to access the granulate material at a rate suitable for the user. This is accomplished through a container body, a removable cap, and a measuring cup. The removable cap further includes a plurality of spouts and is configured to removably attach to the container body, while the measuring cup is configured to removably attach to the removable cap. These components work in conjunction to form a multi-purpose container configured to facilitate the pouring of the material held within the container body at a desired flow rate.

Abstract: Containers are disclosed, as well as multilayer films used in such containers, which advantageously maintain a high seal strength even after being subjected to retort conditions for sterilization. These retortable containers and multilayer films are also beneficially self-venting upon exposure to microwave heating, when the internal container pressure exceeds a threshold value. The self-venting nature of these containers arises from particular sealing characteristics, in which the seal width differs in defined, self-venting seal regions, relative to non-venting seal regions of a given peripheral seal. Particular structural features and geometries of the self-venting seal regions can be used to improve the location of venting and control of the vented gases.

Abstract: A resilient vacuum relief valve 52 is urged tightly on the lid stem 44 engaging the lid bottom 42 while encircling the vent 46 preventing air passage through the vent 46. The vacuum relief valve 52 is also formed of a pliable, resilient thermoplastic such as silicon and is in an inverted hat shape or dish shape as shown in FIGS. 8 and 9 and includes a circumferential outwardly extending rim 54 on top that has sufficient resilience to deform when exposed to negative pressure. This arrangement provides an air tight seal when the lid 38 is inserted into the canister body 22 and while it remains stationary, however, when the lid 38 is pulled upwardly, negative pressure within the canister 20 is created, forcing the valve 52 to break its seal and relieve the newly created vacuum within the canister 20 allowing it to be easier to dislodge the lid 38 and preventing dispersal of powdered contents out of the canister 20 during lid removal.
