Embodiment Construction

[0026] Figures 1 to 3 Indicates a food storage container 15 ( Figure 4 ) is a schematic cross-sectional view of the first embodiment of the pressure indicator 6 of the present invention. according to Figures 1 to 6 , The pressure indicator 6 is connected to the valve device 1, and the valve device 1 is installed on the container cover 2. The pull-tab 7 is integrally connected to the container lid 2 in a one-piece construction by means of a film hinge 32 . The pull-tab 7 and the container lid 2 are injection-molded by heat-resistant thermoplastic material. The pull-tab 7 is basically an oval plate in plan view, with a connecting mechanism 9 used as a suction hole for a vacuum pump, the connecting mechanism 9 basically consisting of a smooth annular surface 18 on the outer side 24 of the pull-tab 7 and one or more holes in the annular surface 18. A suction hole 17 is formed. Such a device is described in the patent application "Device for Evacuating Storage Containers fo...

Abstract

The invention relates to a pressure indicator (6) for a storage container (15) for food. Said container can be closed in an airtight manner and comprises a connecting device (9) for a vacuum pump used to evacuate the air from inside (22) the storage container (15). The invention is characterised in that the pressure indicator (6) is embodied in the form of a dome-shaped membrane which can fold up into itself. One such pressure indicator (6) facilitates the air evacuation process as the user can see immediately when or if there is still a sufficient vacuum inside (22) the storage container (15). The inventive pressure indicator (6) provides an optically and haptically detectable signal corresponding to the pressure state inside the storage container (15).

Description

technical field [0001] The invention relates to a food storage container pressure indicator according to the preamble of patent claim 1 . Background technique [0002] Systems for storing food in the home are already known which allow food to be stored in better storage conditions than if it were stored without any treatment or improved storage conditions. One way to improve food storage is to keep it in vacuum containers. These systems have proven to be very effective in preventing the growth of certain microorganisms, pests, mold and fungi. Also, this helps to prevent oxidation of the food, avoiding loss of moisture and aroma in the food. However, maintaining a sufficient vacuum in the storage vessel is difficult in these types of systems, especially over extended periods of time. [0003] According to WO 88 / 00560, visual inspection is possible using a container lid, the specification therein describing an opening mechanism for plastic beverage cans. Beverage cans have...
