A vacuum packaging device according to the present invention comprises: a vacuum packaging unit for vacuum-packaging a packaging sheet; and a cutting unit provided on the vacuum packaging unit so as to form a notch for tearing on the packaging sheet.

A pouch or pocket may act as a container and may be used to securely hold objects (e.g., cell phone, keys, wallet, etc.) during athletic activity (e.g., running). The pouch may be a standalone item or integrally formed as part of other items. The pouch may hold the object to be stored in place within the pouch or pocket. The pouch may provide some cushioning or impact force attenuation to protect the object being held within the pouch or pocket. Additionally, the pouch may be attached to a garment, such as running clothes. The pouch includes an outer envelope sealable by a closure and a one-way valve with foam layers located inside the pouch. After the object is placed in the pouch, the closure is closed, and the air within the pouch is expelled via the one-way valve by compressing the foam layers from the outside.

A system and method for storing perishable items under controlled atmospheric conditions is provided. Total atmospheric pressure within a vacuum chamber containing the perishable items is reduced to below a predetermined total pressure limit. Oxygen partial pressure within the chamber is monitored. When the Oxygen partial pressure falls below a predetermined lower Oxygen partial pressure limit, an Oxygen-containing gas is admitted to the vacuum chamber to raise the Oxygen partial pressure above the lower Oxygen partial pressure limit. Total atmospheric pressure within the chamber is also monitored. When the total atmospheric pressure reaches or exceed the predetermined total pressure limit, total pressure within the vacuum chamber is once again reduced below the predetermined total pressure limit.

The present disclosure relates to a vacuum preservation device, comprising a drawer including a drawer panel at the front end of the drawer, and a handle assembly. The handle assembly is coupled to the drawer panel, wherein the handle assembly includes a door body sealing assembly and a handle. A preservation container body comprises a preservation container body fixing part and a preservation container body sliding part. An electric push rod is coupled to the preservation container body and is coupled to the preservation container body sliding part and to the preservation container body fixing part.

The present application discloses a vacuum sealed container, including a container body, a container lid, a vacuum generator, at least one magnifier and an indicator. The container body includes a first wall and a bottom surface, wherein the first wall and the bottom surface define an accommodation space. The container lid is coupleable to the container body. The vacuum generator is coupled to the container lid to evacuate fluid from the accommodation space. The at least one magnifier is coupled to the container body. The indicator is coupled to the container. A method for using the aforementioned vacuum sealed container is also disclosed.

A vacuum bag is disclosed. The vacuum bag may include a body. The body may include a plastic layer and a fabric layer. The plastic layer and the fabric layer may be welded together on at least one portion of the body. The vacuum bag may further include a seal bar and a valve.

An evacuated bottle system including a bottle defining a hollow interior, the bottle having a neck defining an opening that provides fluid communication with the interior; a cap assembly including a funnel having a first portion and a second portion, where the second portion extends radially outward from the first portion to form a floor on an interior thereof and a shoulder on an exterior thereof, the first portion defining a first bore and the second portion defining a second bore fluidly connected to the first bore; a self serum stopper having a self sealing membrane that extends radially outward to overlie at least a portion of the floor of the funnel; and a cap having a cap wall sized to fit over the funnel and a cover portion extending radially inward from the cap wall.

A vacuum storage bag assembly includes a zipper bag and a vacuum valve. An opening is formed on the zipper bag. The vacuum valve is connected to the zipper bag. The vacuum valve includes a valve seat, a filtrating component and a check valve. The valve seat is disposed on the zipper bag. The valve seat includes a connecting port and a communication channel communicated with the connecting port and with interior of the zipper bag via the opening, and the connecting port is configured to be connected to a vacuum source. The filtrating component is disposed on an upstream portion of the communication channel. The check valve is disposed on a downstream portion of the communication channel and allows fluid to flow from the interior of the zipper bag, through the filtrating component, and to flow out of the connecting port.

An evacuated bottle system including a bottle defining a hollow interior, the bottle having a neck with a rim defining an opening; a cap assembly supported on the bottle, the cap assembly including a funnel having a first portion and a second portion, the first portion being insertable within the interior of the bottle and the second portion engaging a portion of the bottle to support the funnel above the rim, the funnel defining a bore that fluidly communicates with the hollow interior of the bottle; a self-sealing membrane that covers the bore formed by the funnel to selectively seal the hollow interior of the bottle; a cap attachable to the bottle, the cap including a cover portion that extends at least partially over the self-sealing membrane to restrain movement thereof, the cover portion being axially spaced from the self-sealing membrane to define a gap that permits axial movement of the self-sealing membrane to selectively open the bottle to fluid communication outside of the bottle.
