Definitions

  • the invention relates to a food storage container for hermetically sealing foodstuffs to be stored inside the container, having a vent opening provided with a vent and a vacuum pump connection device for evacuating the interior of the container, the connection device comprising at least one suction opening and one substantially smooth, around the suction opening encircling edge for receiving a sealing lip of a Sauganschtusses for the vacuum pump.
  • the invention further relates to a method for hermetically sealing and opening the storage container.
  • a storage container is known from US 5 735 317 C, which can be put under vacuum by a suction pump and maintains the vacuum for the preservation of food for a long period of time.
  • the storage container has at least one air hole, which can be closed by a metal pressure plate.
  • a pressure part is provided with a spring flap.
  • a pressure lever is lowered and tilted over this, the metal pressure plate, so that an air passage is created for the inflow of air through the air hole into the container interior.
  • the vacuum pump is placed to evacuate the storage container above the pressure part on a coupling flange which surrounds the air hole and is supported on the lid of the storage container.
  • the well-known storage container is relatively expensive due to its components required for evacuation and ventilation (spring flap, pressure part, pressure lever, metal pressure plate).
  • Lid for storage containers for foodstuffs are also known from the prior art, in which a venting or venting valve is provided in the container lid for equalizing pressure during the warm-up process in a microwave oven.
  • EP 0 633 196 A2 proposes a venting valve in the lid of the food storage container, which is to be opened before the container is introduced into the microwave oven. The water vapor then formed during the warm-up process can thereby escape unhindered without a corresponding vapor pressure building up in the interior of the sealed container.
  • EP 0 820 939 A1 Another object of EP 0 820 939 A1 is to prevent the build-up of overpressure in the interior of containers of food storage containers to be warmed up in a microwave, i.
  • a ventilation option for storage containers for food is to be made available in order to be able to safely heat the food stored therein with the container lid closed in a microwave oven.
  • a valve mechanism is described which can be opened via a joint such as a rocker. Thus, only the depression of the rocker arm is required, which can be easily opened the valve.
  • WO 88/00560 describes an opening mechanism for a plastic beverage can. It should first be created by the opening of a vent valve pressure equalization, whereby subsequent opening or removal of the entire lid should be facilitated. These are always according to the task of plastic lid, since just the use of metal lids should be prevented. In particular, the pressure compensation of overpressure in the interior of the container, which is formed, for example, by carbonated drinks, plays a role.
  • US 3,737,066 discloses a container, which is preferably intended for storage of liquids whose side walls are made of coated cardboard material and whose bottom and ceiling elements are made of plastic plates, which are liquid-tightly connected to the cardboard walls.
  • the upper plastic lid has a resealable opening mechanism, which also consists of plastic and is positively connected to the lid via retaining pin. Aeration before opening the container lid or a device for pressure equalization is not provided.
  • the CH 304 374 discloses a closure cap for a sterilizing vessel made of aluminum, which is formed substantially annular and mounted on a cylindrical aluminum container. Between the edge of the lid and the upper rim of the container, a rubber seal is applied. In the middle of the container lid an additional opening is introduced, which is covered by a rubber cap. The rubber cap is used for visual inspection to indicate if there is a vacuum inside the container. As long as a corresponding negative pressure in the container interior is present, the rubber cap bulges inward accordingly. With decreasing vacuum, this curvature decreases continuously. Therefore, it is difficult for the observer to decide whether the negative pressure existing inside the container is still sufficient to ensure the freshness of the food inside the container.
  • EP 0 234 607 B1 describes a bottle closure which is simultaneously designed as a venting valve. In this case, a cylindrical vacuum pump is applied, which completely covers the protruding cylindrical shaft of the bottle closure.
  • EP 0 644 128 A1 describes a sealable container which can be evacuated by a vacuum pump. Therein, a check valve is disclosed, which is accommodated in a cylindrical recess in the container lid and into which the suction opening of a vacuum pump is introduced.
  • a storage container for food is known, the filling opening is closed by a lid.
  • the lid has a ventilation opening in the center on, which is closed by a valve member.
  • the valve member has an opening tab, over which the valve member lifted from the vent and thus the vacuum located in the storage container can be reduced.
  • a vacuum to be formed in the storage container is achieved when the valve is closed by cooling the food after a cooking process.
  • a storage container of the type mentioned is also known, which is hermetically sealed by a valve provided with a lid.
  • the valve is centrally located in the lid and is surrounded by an annular connection device on which a vacuum pump for venting the food compartment of the storage container can be placed.
  • the valve plate In order to open the storage container, the valve plate must be lifted from the sealing edge formed on the lid, which can be done by an operator with a knife or other pointed object under the valve plate and pushes it upwards. Such an opening mechanism is relatively difficult to operate.
  • the present invention has for its object to provide a storage container for food of the type mentioned, which can be evacuated in constructive and procedural simple manner and opened in the evacuated state.
  • the storage container according to the invention is inter alia characterized in that the connection device is formed on a pivotally mounted opening tab for the valve and the peripheral edge on the outwardly directed side of the opening tab.
  • the invention is characterized, inter alia, by the fact that for venting a hinged opening tab on the storage container for the valve is pivoted outwards. As a result, a venting of the container interior can be carried out in a simple manner.
  • the storage container with a valve device according to claim 1 has the advantage that it is simple and inexpensive to produce. Furthermore, a centering of the vacuum pump is not required due to the structural design of the connecting device.
  • a suction device can in particular a device with circumferential sealing lip, which acts as a suction cup, are used.
  • the suction surface of the sealing lip has no structure, so that the suction power can completely serve the evacuation of the storage container.
  • the suction opening within the smooth peripheral edge may have any cross-section. It can also be wavy in a circle, it is only important that then the circumferential sealing lip of the suction device is adapted to this course to produce a tight connection.
  • the opening tab in the vacuuming of the second embodiment, is pressed by the motor-driven vacuum pump against the foot portion of the sealing tongue and a pressure indicator, so that a sealed valve device is formed and at the same time the pressure indicator is clearly visible.
  • the opening tab presses against the holding member, which in turn presses the seal securely against the container lid.
  • the pressure gauge is easy to read.
  • An advantageous embodiment of the present invention provides the features of claim 4. This provides an integrated component with few individual parts. As soon as the storage container is evacuated, the sealing effect is automatically achieved by sucking the sealing tongue against the vent opening in the container lid.
  • a further advantageous embodiment of the invention provides the features of claim 5.
  • This embodiment provides a surprisingly simple constructive solution for easy opening of the container lid, since initially when pulling the opening tab over the driver, the sealing tongue is lifted from the vent opening. As a result, a pressure equalization between the container interior and the environment takes place. The container lid is no longer sucked by the negative pressure inside the storage container and can be easily lifted off this.
  • the valve device thereby fulfills several functions.
  • Yet another advantageous embodiment of the present invention comprises the features of claim 8.
  • the evacuation process is simplified because of the Operator is immediately apparent when a sufficient negative pressure in the storage container is reached.
  • a multiple function component is created.
  • the embodiment described therein provides a visually and haptically detectable pressure indicator available.
  • the optical effect of the membrane for example, made of elastomeric plastic material can be increased by appropriate color design in a signal color.
  • a corresponding haptic effect can be achieved, which also allows visually impaired users to detect the pressure state in the interior of the storage container.
  • a further advantageous embodiment of the invention provides the features of claim 11. This makes it possible to store the storage container and its contents in a freezer and then thaw in a microwave oven. For the warm-up process in the microwave oven while the vent can be opened as already described on the opening tab. Possible materials are polypropylene and polyamide as well as any other thermally stable and taste-neutral plastic material.
  • a material is preferably selected which has both sufficient rigidity and the required sealing properties.
  • This component can be inexpensively manufactured as an injection molded component and easily mounted on the storage container.
  • an alternative embodiment provides the features of claim 13.
  • the container lid and the opening tab can be produced as a common injection molded part.
  • an elastic elastomeric plastic or rubber material can be used, which is then inserted into the component formed from the container lid and opening tab.
  • the opening tab not only serves to open the vent opening, but also the entire container lid can be lifted over the film hinge.
  • a further advantageous embodiment of the present invention provides the features of claim 15.
  • the advantage here is the flexible arrangement and universal applicability of the valve device together with storage containers for food.
  • the method according to claim 19 is simple and quick to carry out. Due to the low demands that the procedure places on the user, it is particularly well suited for the household sector. In particular, it is advantageous that due to the combination of the connection device with a smooth edge and the suction connection with circumferential sealing lip, no complicated centering is required before the evacuation process.
