DE2354093A1 - Compressible closed container for perishable goods - has valve preventing air entry and dispensing only under external pressure - Google Patents

Abstract

The container is particularly for use with foodstuffs and perishable materials, being of variable volume. A discharge valve prevents air entering, and allows dispensing of the contents only when external pressure is applied. When this occurs, the contents are forced out through the valve and the container volume is reduced. The container can be of concertina shape, and the valve of elastic material, with openings so shaped that they expand with internal pressure, and close when this falls. A stop can be mounted on the valve, to prevent it inwards distortion under external pressure. An elastic absorption component can be mounted on the container near the valve.

Description

Compressible fteechlosserxfcr container with -'Emptying valve for liquids and pastes. ■. ;

Compressible closed container with drain valve for Liquids and pastes, such that the container casing is like an accordion is formed and by external pressure on the container liquid or paste can emerge from the emptying valve, which is arranged at any point, and when the pressure on the container closes the drain valve automatically, and thus no air can get into the interior of the container to the To ensure the storage life of the container contents, after complete emptying the container is reduced in size by a multiple of its volume. The accordion-like container without. Drain valve can also open after emptying through the usual> ceiling !. can be reduced by a multiple of its volume.

There are known containers in many variations. You do have one, however non-compressible container shell in common. They are also provided with screw caps, push-in lids, "etc., so that with, or after partially wise emptying of the contents air into the container interior can get. This increases the shelf life or usability, especially for foodstuffs, paints, etc. greatly reduced. In addition, screw caps that do not go with you connected to the container are easily lost. Furthermore, dangerous use is caused by such known containers designed in this way Small children easily given when filled with harmful media. Another disadvantage of the well-known plastic containers, Glass, sheet metal or the like with a single use is the waste volume after emptying, which corresponds approximately to the content.

The object of the invention was to provide a collapsible container for liquids or pastes, which is provided with a drain valve is that, at a certain pressure on the container, the medium can escape until the pressure ceases v / is effective, wherein the drain valve is designed so that no atmospheric air can get into the container. This is in spite of partial emptying, especially with food, colors, certain Pastes or the like the shelf life, the usability and the quality as with not yet opened containers

give. Furthermore, the container can be emptied completely or partially without prior removal of screw connections or the like take place. The drain valve can be fixed or detachable, the removable training for filling or refilling the Container is used. The container outer jacket is preferably designed like an accordion or the like, the formation of the folds, the depth and distance of which are dependent on the thickness of the container wall and the elasticity of the material. The dimensional stability of the container in the Its largest surface level is greatly increased by the folds or the like provided. In use, the container is from Press to press more tightly together, with it moving through the prevented air admission cannot expand again, so that the degree of its emptying can already be recognized from the outside. In addition, a small volume of waste is achieved in the container after it has been completely emptied. The latter also relates to the invention Container without an emptying valve, which is slightly compressed after emptying can be. As a further embodiment, the drain valve according to the invention can be provided for tubes. .

The invention is illustrated using exemplary embodiments. Show it:

a certain pressure F on end faces 1a or 1b creates a hydrostatic one Pressure in the interior of the container 1, which, with the diameter j) i, the opening 2a cannot be changed, due to the expansion of the material in the drain valve 2 causes and enables the container contents 3 to exit. If the pressure F ceases to apply to the end faces 1a or Ib the hydrostatic pressure drops and causes the opening 2a of the drain valve 2 to close by contraction of the material. The drain valve 2 is preferably made of elastic material, e.g. rubber. The opening 2a is in the rest position of the drain valve 2 closed and -admittedly when there is no hydrostatic pressure through Pressure F is generated. According to the elasticity of the drain valve 2 and the predetermined pressure F, which is preferably by hand is exercised, the diameter DZf and thus the · pressure-absorbing ■■ · Area of the drain valve 2 dependent. The end face Tb is with a valve holder Ic provided, which is fixed or detachable can be. Furthermore, the drain valve 2 is arranged airtight in the valve holder 1c. The distance W and the depth correspond to the elasticity and material thickness S of the container jacket Determine (D1-D2) x2 of the folds.

Fig. 2 shows the compressed, emptied container 1 in Height H2, which corresponds approximately to the height H3 of the valve holder Ic. The height H2 results from the sum of the material thickness S- of the container jacket 1 .

For the application of liquids and pastes 3, the preferably elastic-absorbent element ί \ - with one or more passages Ι + ά is shown in FIG. K in the area of the drain valve 2. The passages 4a "are in communication with the opening 2a of the spill valve?. The protective cap 5 serves to prevent contamination of other items during storage of the container. 1.

fixed. The protective cap 5 can be clamped or screwed on the container be arranged.

The drain valve 2 according to the invention can, as shown in FIG. 5, be arranged in a tube-shaped container 1. The hydrostatic Pressure inside the tube can be achieved by rolling it up or squeezing it can be achieved. The fixation of the drain valve 2 is achieved by end face 1b and limitation Ie.

There are still various forms of embodiment of the drain valve 2 and the container 1 possible. Thus, the container 1 can be not only cylindrical, but also differently, e.g. square, rectangular, etc. be trained. In addition, the container 1 is without arranged Emptying valve 2 is advantageous not only for liquids and pastes, but also for canned food, since the container can be easily compressed to a minimum volume of waste after it has been emptied can, with today's consumption of containers in the household and Industry for garbage collection, transportation and disposal is beneficial. The drain valve 2 can also be of various shapes be designed and arranged. Thus, instead of the opening 2a in the drain valve 2, the opening can also be provided in the valve holder which is opened or closed when the drain valve is pushed in or moved. In addition, the drain valve "be designed as" a spring-loaded ball. Preferably the drain valve is 2 provided with a protective film or the like before emptying it for the first time, which can be torn off or removed manually can be so that when the containers are stacked, the storage pressure or an unintentional pressure will not be effective.
