Definitions
- the invention relates to a device for pressurizing a opened food container, such as in particular a bottle or packaging, an overpressure or a negative pressure or vacuum being generated by appropriate pressurization in order to preserve the remaining content of the opened food container or to dispose of one from a deformable one Compress material existing food container.
- PET plastic bottles in particular take up a relatively large amount of space during disposal, which corresponds to their full volume. The one in one Space available for each container is therefore essentially taken up by the empty space of these bottles.
- the aim of the invention is to provide a device of the type mentioned at the outset, which is versatile in use and simple to handle with a simple structure.
- a hand-held device with a pump and an electric motor driving it, as well as by at least one pressure adapter serving to generate an excess pressure and at least one vacuum adapter, the pressure adapter or the vacuum adapter being able to be used between the relevant food container and the hand-held device, in order to produce the connections required for generating the excess pressure or the vacuum between the pump and the interior of the food container to be acted upon and the atmosphere, so that the respective function of the handheld device is determined by the adapter used in each case.
- one and the same hand-held device can be used both for generating an overpressure and for generating a negative pressure or vacuum.
- the respective function of the handheld device is determined by the adapter used in each case.
- the desired overpressure or vacuum is achieved relatively quickly, even with larger containers and an already extensive emptying.
- the escape of carbon dioxide is prevented by generating a corresponding excess pressure in the air-filled space of the container in question.
- Oxidation of wine is prevented by pumping air out of the bottle in question and thereby creating a corresponding vacuum in the relevant empty space of the bottle.
- PET plastic bottles can be flattened within a few seconds by creating a corresponding vacuum, so that disposal which takes up little space is possible.
- the contents of food packaging can be preserved by creating an appropriate vacuum in these packaging.
- the device according to the invention is thus versatile and easy to handle with a relatively simple construction, and due to the pump driven by an electric motor, the required delivery rate for the desired overpressure or vacuum is always provided.
- the hand-held device is preferably provided with a centering pump coupling, to or into which a respective adapter can be inserted or inserted.
- the pump coupling comprises a connection surface, into which at least one suction channel and at least one pressure channel of the pump open and to which a connection surface of a respectively docked adapter can be placed, into which air channels of the relevant connections with the pump are made Adapters open, two preferably concentric O-rings being provided between the connecting surface of the pump coupling and the connecting surface of a docked adapter, through which the suction and pressure channels of the pump opening into the connecting surface of the pump coupling are sealed against one another and to the outside in order to provide a tight seal To maintain connection between these channels and those of the docked adapter.
- the O-rings can be used, for example, in ring grooves which are provided in the connection surface of the pump coupling.
- the pressure channel of the pump opens inside the inner O-ring and the suction channel of the pump in the area between the two O-rings into the connection surface of the pump coupling.
- the pressure adapter expediently comprises a check valve, via which compressed air supplied by the pump to the food container in question can be supplied, while preventing air from escaping from the container.
- the vacuum adapter advantageously comprises a check valve, via which air is sucked out of the food container in question, while preventing air from entering the container.
- the pressure adapter can advantageously be screwed onto the relevant food container.
- the vacuum adapter can expediently be plugged onto the relevant food container.
- the pump and the electric motor are accommodated in a housing of the hand-held device, preferably made of impact-resistant plastic.
- the electric motor can be powered by a battery pack or also by a power supply. If a battery pack is used, it is preferably accommodated in a separate housing, in particular made of impact-resistant plastic, which can expediently be detachably coupled to the housing containing the pump and the electric motor, for which purpose, for example, a clip coupling can be provided.
- the pump is preferably a cell pump and it expediently consists of a graphite approved for foodstuffs. In addition, it is preferably maintenance-free and vibration-free during operation. In addition, such a pump is expediently used, which at most produces a slight abrasion even after a longer period of operation. This abrasion can be caught in particular by an exchangeable filter.
- a piston, diaphragm or screw pump can also be provided.
- a limit switch is advantageously provided, via which the electric motor driving the pump is automatically switched on when a respective adapter is docked onto the pump coupling and is automatically switched off when the adapter is removed.
- a control unit in particular formed by a microchip, can be provided for function monitoring, by means of which the electric motor is automatically switched off as soon as a predeterminable overpressure or a predefinable vacuum is reached.
