A system includes a storage bag having an interior volume for containing food items and a one-way valve element through which air from the interior volume can be evacuated. The system further includes an evacuation device having an inlet opening. To evacuate storage bag, the inlet opening is placed directly adjacent a pliable sidewall of the storage bag about the valve element. The placement of the inlet opening against the flexible sidewall will seal the interface between the valve element and the inlet opening facilitating the evacuation of the interior volume.

A storage system for storing and preserving food items or the like includes a sealable storage bag (100) having attached to it a one-way valve element (130) that communicates with the interior volume of the storage bag. The system also includes an evacuation device (150) that can be positioned over the one-way valve element to evacuate air entrapped in the interior volume via the valve element.
摘要:
Systems and methods for preserving a perishable material sensitive to oxygen and bacterial spoilage are taught. The systems in some embodiments comprise a pressurized source of a first gas (13) other than oxygen and a container for the perishable material (31), the container having a sealable lid (33), a passage including a one-way valve through the lid connected by a gas conduit to the pressurized source, and a mechanism (20) for venting the container. In various embodiments oxygen exposure to the perishable material in the container is diluted by at least one cycle of pressurizing, the container with the first gas other than oxygen, and then venting the container. In some embodiments oxygen dilution is by vacuum.

A container lid assembly (2) that includes an integral pump (6P) so as to create pressure differential within a container. This pressure differential may be lower than atmospheric pressure so as to be at least a partial vacuum within the container. Alternatively, the pressure differential may be a state of higher than atmospheric pressure within the container. There are several features of the present invention that can be used in synergy, but are of value when implemented separately. These features include a pump configuration (120) that activates the reciprocating linear motion of the piston (10) by the rotational movement of a pump actuating element; a contents-dispensing mechanism (150) for removing contents from the container while maintaining the at least a partial vacuum within the container; a vacuum indicator; and a filter configured to filter the gases entering the pump from the interior of the container.

A machine (1) for vacuum packing in plastic bags and rigid containers (37) comprising: - an airtight chamber (4), suited to accommodate a plastic bag (26) with the relative product (27), - means for sucking air from said chamber (4), so as to create a vacuum in the chamber and in the bag (26) contained therein, - means for sealing the edges (25) of the bag (6) after the vacuum has been created therein, - air input means (13) for introducing air into the chamber (4) to remove the vacuum, - a suction device (35), connected to the suction means, for creating vacuum in rigid containers (37) provided with a valve (39).
摘要:
The invention relates to a vacuum pump for bottles, which is particularly suitable for wine bottles which have been opened but not completely consumed. The inventive pump consists of a support (1) which can be connected to the neck (4) of the bottle and which comprises an inner constriction (2) that rests on the mouth (3) of said bottle. The aforementioned constriction forms the support and the head (7) of a stopper (8) which penetrates the mouth (4) of the bottle and which is solidly fixed thereto. Moreover, the invention also comprises a cover (19) which can be moved axially in relation to the support (1) and which forms a variable-volume chamber (22) along with said support and the head (7) of the stopper. According to the invention, a unidirectional valve (11-14-16) is formed in the stopper (8) and a second unidirectional valve (20-21) is formed between the support (1) and the cover (19) such that, when the chamber (22) increases, air is drawn from inside the bottle and, when the chamber decreases, said air is released to the exterior.
