A container cover for storage container includes a rotary device, an outer cover member, an inner cover member, a first guide block, second guide block, a pumping piston and a piston seat so arranged that when the rotary device is driven by a user to rotate the first guide block, guide rods of the first guide block are moved along a first continuous wave-shaped track of the second guide block, causing the second guide block and the pumping piston to move alternatively up and to further pump air out of the storage container through an air-pimping hole of the piston seat to create a negative pressure. Further, a first spring member an upper rail seat can be provided to balance the movement of the pumping piston and to stabilize the rotation of the first and second guide blocks. A relief valve rod can be selectively used for giving a visual indication indicative of the presence of a negative pressure in the storage container.

A resealable, vacuum packable receptacle has a container, a sealing layer, an inner lid, and an outer lid. When (i) the outer lid opening receives the inner lid, (ii) the inner lid is threadably mated with the container, and (iii) the container has the sealing layer positioned over the container's mouth; (A) a portion of the outer lid causes the outer lid or the inner lid to contact the sealing layer to push a desired amount of air from the container which then results in inhibiting air from entering or exiting the container, or (B) the distance between the outer lid's top surface and the inner lid's top surface can be altered, and when the distance is increased, the air pressure in the container is decreased.

A lid for an insulated container comprises a flexible gasket configured to facilitate a seal between the lid and an inner wall of the insulated container, and further configured to expand into an interior compartment of the insulated container responsive to a vacuum developing in the interior compartment. A diaphragm chamber is situated opposite the flexible gasket from the interior compartment when the lid is fully engaged with the insulated container. One or more air channels couple the diaphragm chamber to an exterior of the lid. The development of a vacuum in the interior compartment of the insulated container draws a force on the flexible gasket, thereby reducing pressure in the diaphragm chamber. The negative pressure in diaphragm chamber is back-filled with external air, which enters the lid via the air channels. The lid may then be removed without excessive vacuum forces.

A container with a reusable cap, including a glass receptacle (10) with a receptacle opening (11) surrounded by an annular mouth (12) and by a cylindrical neck (13) including a retention configuration; a cap (20) including a closing portion (30) completely covering the receptacle opening (11) and an engagement portion (40) made of a metal sheet; a releasable closure mechanism connecting the engagement portion (40) with the retention configurations and a sealing ring (50), the engagement portion including radial protrusions (41), directed inwards and determining a local narrowing, the sealing ring (50) being not adhered to the cap and being retained within the cap (20).

Container assemblies are described herein that include a metal closure and a container including a plastic finish. The container assemblies may be characterized by improved performance including reproducibility of force needed to remove the closure. Furthermore, the container assemblies described herein may be compatible for use with hot-fill packaging processes.

To modify the headspace in a container to remove vacuum pressure, a container has a seal or cap which may provide a temporary opening into the container which is sealable under compression to provide a controlled raising of the internal pressure as the heated contents of the container cools. A sealing chamber (84) may enable the introduction of a fluid into the headspace (23b) to force the fluid level (40) lower. Other methods and apparatus are described.

There is provided herein a lid for a vacuum storage container, which contains a lid body having a top side and an opposing bottom side, the lid comprising a pressure-release valve having a vacuum-sealed position and a vacuum-release position, and a collar on the bottom side of the lid body having an open end, the pressure-release valve extending from the top side of the lid body into the collar on the bottom side, and a sheath covering the open end of the collar on the bottom side, which sheath reduces a vacuum loss when the pressure-release valve is in the vacuum-sealed position while permitting a release of vacuum when the pressure-release valve is in the vacuum-release position.

Systems and methods for filling containers with heated fluids are described. In some embodiments, a method may include one or more of introducing a fluid through an open end of the container, providing a seal or cap to close and seal the filled container, cooling the heated fluid to create a first internal vacuum pressure, providing a pressurizing chamber, providing or creating an opening through the seal or cap, providing at least one fluid through the opening or aperture, and sealing the opening or aperture under a second internal pressure higher than the first internal vacuum pressure.

It is desired to make an improved lid suitable for pails, overcoming the problem of existing complexities and leaks. The invention is achieved by a lid (300) having a lid skirt (320) provided with an inner collar (328) that engages an outer collar (222) of a sidewall (220) of a pail (200), the lid skirt (320) being provided with a fastening mechanism (330) for tightening the inner collar (328) around the sidewall (220) below the outer collar (222). Corresponding to the lid (300) a pail (200) is provided having a simplified structure that is supported mechanically by the lid (300). Furthermore, a thermally insulated compound pail is disclosed, the compound pail comprising a first inner pail (200) that is inserted into a second outer pail (200) such that a space (404) is formed between said pails (200).

A resealable, vacuum packable receptacle has a container, a sealing layer, an inner lid, and an outer lid. When (i) the outer lid opening receives the inner lid, (ii) the inner lid is threadably mated with the container, and (iii) the container has the sealing layer positioned over the container's mouth; (A) a portion of the outer lid causes the outer lid or the inner lid to contact the sealing layer to push a desired amount of air from the container which then results in inhibiting air from entering or exiting the container, or (B) the distance between the outer lid's top surface and the inner lid's top surface can be altered, and when the distance is increased, the air pressure in the container is decreased.
