DESCRIPTION:
BRIEF SUMMARY
The invention relates to a container having a closure, for the accommodation of fluid products which can be removed in portions by the application of pressure to the flexible container.
The term "fluid products" is to be understood to mean all liquids as well as pastes and creams of different consistencies, and foods of comparable nature, such as syrup, mustard or ketchup. Thus, containers of this kind, from which a product is forced out by exerting pressure on the container, contain for example liquid soap, lotions, toothpaste, deodorants etc., or foods such as mustard, mayonnaise etc. Many products of this kind are marketed in squeeze tubes, but these tubes have the known disadvantages that one often forgets to replace the screw cap, so that the product dries out, or is altered by the access of air which for example oxidizes it or spoils it. Another disadvantage consists in the fact that tubes that have been squeezed or rolled up from one end are unsightly, when the contents have been withdrawn carelessly and are smeared around the edge of the opening.
Furthermore, a variety of containers for the accommodation of products of the kind described above are known, and are preferably made of soft plastic with valve-like closures. Many of them, however, have the disadvantage that, when in use, they do not work or cannot be actuated at all in some positions, or that, since the center of gravity of the container is unfavorably located, it easily falls over when only partially full. These known closures for the removal of the content in portions usually do not protect the content against undesirable access of air, or from the oxidation or spoilage of the product.
The problem on which the present invention is based was therefore to create a container having a closure, which would be just as inexpensive as a squeeze tube, but which would not have its disadvantages. The container was to permit an amount of the contained product to be withdrawn as often as desired without losing its original external shape, requiring only a pressure on the container without removing a screw closure or having to replace it. The product at the same time was to be able to be sealed off air-tight, again without such a screw closure. The container was to be able to be used while it stands upright on its base or in any other position, and its peripheral surface was to be able to be of any desired shape, such as cylindrical or polygonal, so as to have a great variety of possible configurations. It was furthermore to be possible to reuse the container with a refill.
For the solution of these problems, the container with a closure has the features according to the independent claim 1. Preferred embodiments will be seen in the dependent claims.
The invention is further explained with the aid of the drawings wherein different embodiments of the subject matter of the invention are represented only by way of example.
FIG. 1 is a cross section through a double-walled container whose closure is shut,
FIG. 2 is a cross section of the container of FIG. 1 whose closure is open,
FIG. 3 is a cross section of a container similar to FIG. 1, with a modified embodiment of the container lid,
FIG. 4 is a cross section of a double-walled container whose cover has a discharge passage at an angle,
FIG. 5 is a cross section through a double-walled container similar to FIG. 3, with a modified embodiment of the air valve,
FIG. 6 is a detail in the area of the air valve, as seen in the direction of the arrow A,
FIG. 7 is a detail on a larger scale of a variant embodiment of the closure,
FIG. 8A is a detail on an enlarged scale of the upper part of the closure of a container which is not shown, showing a modified embodiment having a side orifice and a mechanical lock in the closed state,
FIG. 8B is an embodiment similar to FIG. 8A, having a manually operated mechanism for opening and closing disposed opposite the discharge orifice,
FIGS. 9A and B represent another modified embodiment of a closure whose orifice can be controlled by air and/or by the fluid product,
