A system for preserving a surgically explanted tissue sample has a first packing station for placing the tissue sample in a selected container among a plurality of containers of different sizes. Each container has a hermetic lid (50) with an opening (33) equipped with a non-return valve (51). The system also has a final packing station equipped with a filling system for filling the selected container with a preservative substance, including a nozzle-holding head (28) mounted movable on a vertical guide (29). A method is also described which provides for the selection of the container based on the evaluation of the volume of the tissue sample, the hermetic closure of the container immediately after the insertion of the tissue sample, and the filling of the container by means of a nozzle (31) of a filling system inserted in the non-return valve (51) of the hermetic lid (50).

A valve assembly is provided for use with a food storage container, including an opening formed in its lid member with at least one air channel formed between the container and the lid member. The valve assembly can be operated by a knob that, in a first position, unseats a check ball from a valve seat so that the valve assembly operates as a two-way valve able to work with a vacuum adapter in “marinate” mode or to open the lid member. In a second position, the check ball of the valve assembly unseats from the valve seat so that the valve assembly operates as a one-way valve that is operable to work with a vacuum adapter in “vacuum” mode to preserve the freshness of food contained therein. The valve assembly can be used with a vacuum system as part of a food storage container system.

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.

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.

Modular containers are formed in a collapsible fashion by flexible or rigid bodies and panels. A size of a modular container may be selected by inflating the modular container to a desired pressure or volume, coupling two or more bodies of the modular containers together, or mating the bodies of the modular containers to common bases or surfaces. The modular containers may be accessed via one or more openings in vertical or horizontal surfaces of such modular containers in order to load items into such modular containers or to unload the items therefrom. The modular containers may be assembled or collapsed manually or automatically, and transported to one or more locations separately or in stacks.

Disclosed are a container cover and a vacuum preservation container. The container cover comprises a cover body and an air extraction assembly, wherein a first through hole is provided in the cover body, the air extraction assembly comprises an outer cover and an inner cover, the inner cover is arranged on an upper end of the first through hole in a sealing manner, a second through hole and a third through hole are provided in the inner cover, the second through hole is in communication with the first through hole, a first one-way valve is arranged in the second through hole, and a second one-way valve is arranged in the third through hole.

A laminated package for solid products in powder or grain form, includes a set of stiffening notches, a dispensing mouth with a seal, valves for loading inert gas, in which the lateral folds of the upper face are folded inwards under the front and rear flaps, and the lateral folds of the lower face are folded outward and folded and stuck on the lower face over the front and rear flaps, and a method for forming the package.

The present disclosure relates to the technical field of small household appliances and discloses a separable evacuation device. The separable evacuation device includes an evacuation module. The evacuation module includes a base, which is connected to an opening of a to-be-evacuated container; a vacuum pump, which is disposed on the base and configured to vacuum the to-be-evacuated container; a power supply assembly, which is connected to the vacuum pump and configured to supply power to the vacuum pump; and a control assembly, which is connected to the power supply assembly and the vacuum pump and includes a vacuum pressure switch. The vacuum pressure switch is configured to detect an air pressure value in the to-be-evacuated container and control the power supply assembly to perform one of supplying power to the vacuum pump or powering off the vacuum pump.

An air extracting device (2) at least includes a processor (21), a motor (23), an air-extracting unit (24), and a wireless transmitting unit (25), and a method of the air extracting device (2) for calculating remaining time required for extracting action includes following steps: activating the motor (23) after the air extracting device (2) and a sealed bag (1) are jointed together; driving the air-extracting unit (24) to execute an extracting action by the activated motor (23) for extracting air from the sealed bag (1); monitoring load current of the motor (23) by the processor (21) while executing the extracting action; calculating a remaining time required for the extracting action by the processor (21) according to a variation of the load current; and, transmitting the remaining time required for the extracting action to a mobile device (4) through the wireless transmitting unit (25) for displaying thereon.

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.
