DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a beverage container which is intended for use in serving beverages and which can be readily filled with the beverage to be served in a service locality and thereafter readily closed. The invention also relates to a bottom closure for a beverage container, particularly a package container, intended to hold powder or liquid material, or a beverage package, said bottom closure being particularly usable with a container produced from sheet material.
In hamburger bars and like establishments, beverages are at present normally served in a round mug having a conically upwards and outwards sloping side wall. These mugs are also used with loose lids that can be fitted over the upper rim of the mug. The lid may also be provided with a weakening in the centre of the lid through which a drinking tube, or drinking straw, can be pushed into the mug and therewith into the contained beverage without needing to remove the lid.
One drawback with mugs of the aforedescribed kind is that when filled they have a relatively high centre of gravity which renders the mug unstable, and the aforesaid lid when fitted to the mug is not effective in preventing the beverage from leaking from the container should the container topple over. This is because the container has a relatively tin wall and is therewith easily deformed when it topples, such as to loosen the lid so that the container contents are able to run out.
In the case of package containers or beverage containers which, e.g., are not filled at the time of manufacturing the container with the substance that is to be at least temporarily stored therein, it must be possible to be able to transport and store the containers in a space-preserving manner. It is necessary to find solutions to the transportation and storage problems, particularly in the case of containers that cannot be readily stacked or nested one within the other. One solution would be to provide a foldable container, although the container bottom closure may then cause a problem, particularly when the number of mutually superposed layers of material in the folded container shall not be excessively large.
A first object of the present invention is to provide a novel beverage container in which beverages can be served and which is not encumbered with the aforesaid drawbacks and thus is less liable to topple when filled and with which the contents thereof are less liable to be emptied should the container topple nevertheless.
Another object of the invention is to provide a container of the aforesaid kind which can be handled easily when storing, filling and closing the container.
A further object of the invention is to provide a beverage container of the aforesaid kind which can be readily manufactured, preferably from an environmentally friendly material.
Yet another object of the invention is to enable container, drinking tube and lid to be produced from one single blank.
Still another object of the present invention is to provide for a container of the aforesaid kind a bottom closure which can be readily manufactured in a cost-effective and material-effective manner.
Yet another object of the invention is to provide a bottom closure which when the container is erected or developed from its blank form will contribute to maintaining the container in its erected state and not strive to return to its folded state.
Another object of the invention is to provide a beverage container having a bottom closure in accordance with the invention.
These objects of the invention have been achieved with a beverage container and a bottom closure that have the characteristic features set forth in respective claims.
The invention will now be described with reference to exemplifying embodiments thereof and also with reference to the accompanying drawings, in which
FIG. 1 is a view showing an inventive beverage container blank from above;
FIG. 2 shows a beverage container folded to an erected state from the blank shown in FIG. 1;
FIG. 3 illustrates a blank variant from which a beverage container essent
