ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to containers for squeezeable out materials, such as for example two spaced containers, gel containers, cream containers, etc.
It is known that in known containers after a substantial use of the material accommodated in them, a certain amount of the material is also left over. Also, forcing the material out of the container is many instances uncomfortable.
Some of the squeezing out mechanisms are disclosed for example in U.S. Pat. Nos. 5,071,036, 5,167,348, 5,222,629, 5,277,335, 5,501, 369.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide a container for squeezeable material which avoids the disadvantages of the prior art.
More particularly, it is an object of present invention to provide a container for squeezeable material, which guarantees that the whole volume of the material accommodated in it can be dispensed, and also dispensing of the material or forcing the material from the container is facilitated.
In keeping with these objects and with others which will become apparent hereinafter, one feature of present invention resides, briefly stated in a container for a squeezeable material which has a container part forming an interior for accommodated a material, and a squeezing out mechanism which is displaceable along the container towards its opening and during the displacement squeezes the container so as to squeeze the material from the container, wherein in accordance with the present invention the squeezing out mechanism is provided means for allowing its displacement only in a direction toward the outlet opening and prevents its displacement in an opposite direction.
When the container is designed in accordance with the present invention it eliminates the disadvantages of the prior art.
The novel features which are considered as characteristic for the present invention are set forth in particular in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings.
