BEVERAGE CONTAINER STRUCTURE The present invention relates to beverage containers and, more particularly, to a new and improved beverage container having unique pressure relief valve means as well as an interior, raised, dry ice container.
Familiar to many families are standard beverage con- 7 tainers suitable for dispensing milk or flavored beverages. For those who desire homemade root beer, it is standard practise to include a root beer extract and sugar in a quantity of waterand then to slipdry ice into the container for carbonating the liquid. In conventional containers the dry ice slips to the bottom and its effectiveness may be somewhatreduced. More importantly, the dry ice may stick to the bottom and cause cleaning difficulties; additionally, because of the lowered temperature of the dry ice the same may chance a fracturing or cracking of the container should the same be made of plastic.
An additional problem is solved herein in the desired inclusion of pressure relief valve means as can be uti-.
lized to exhaust pressure, so as to regulate both carbonization of the liquid as well as outward flow.
Accordingly, a principal object of the present invention is to provide a new and improved beverage container.
A further object is to provide a beverage container having a novel pressure relief valve mechanism.
A further object is to provide a beverage container having an interior vessel for receiving dry ice and suspending the same above the bottom of the primary container.
A further object is to provide a beverage container having an interior vessel which can be easily withdrawn by the fingers, and this without the use of any lifting bail or other equivalent additional mechanism.
The features of the present invention may best be understood ,by reference to the following description taken in connection with the accompanying drawings in which:
FIG. 1 is a perspective view, partially broken away, of a beverage container and interior vessel combination, all constructed in accordance with the principles of the present invention in a preferred embodiment thereof.
FIG. 2 is a fragmentary enlarged cross-section taken along the line 22 in FIG. 1.
FIG. 3 is an enlarged fragmentary cross-section taken along the line 3-3 and illustrates the inclusion of a valve proximate the base of the primary container.
FIG. 4 is an enlarged fragmentary vertical crosssection taken along the line 44 and illustrates a representative side of the interior vessel and its cooperation with the interior wall of the outer container; it will be understood that the finger-grip portions, one only being shown, will be disposed on both sides of the interior vessel.
In FIG. 1 liquid container 10 includes an inner wall shell 11 as well as an outer wall shell 12. Disposed therebetween is an expanded plastic material 13 such as Styrofoam.
The inner wall and outer wall shells may join at 14 to form an integral shell unit filled with the expanded plastic as at 13 as seen in FIG. 2. In any event, the outer shell is provided with threads 15 that cooperate with interior threads 16 of lid 17. Lid 17 includes outer and interior walls 18 and 19, respectively. Apertures as at 20 in wall 19 are provided for any gaseous pressure 26 may comprise a disc that is convex upwardly and I made of a spring steel, bywayof example.
The structure as thus far described operates as follows. Assume that a beverage such as root beer is being made as with dry ice deposited within the interior of the container. Excess gaspressures formed will be relieved by virtue of the inclusion of spring 25 and valve disc 26, this by the excess gaseous pressure proceeding upwardly through one or.more apertures 27 in the lidso that the disc '26 is raised upwardly against the pressure spring 25.
In resuming a consideration of the container construction, it is seen that the same is provided with a liquid discharge valve 28 at the base of the primary container. 'These are common in the design of picnic jugs and any one of a number of the types currently on the market may be installed at point A in FIG. 3 in a conventional manner. The particular type of thumb depression valve used, by way of example, forms no part of the invention, standing along.
Of importance is the fact that the interior wall or shell 1 I is conically tapered inwardly as one progresses downwardly. This taper may be of the order .of 5 and comprise simply a draft angle or taper to facilitate molding.
A separate interior container 29 is also provided and includes an outer wall 30 having an outer surface which is conically tapered still further, of the order of perhaps 810. Disposed proximate upper lip 31 are a pair of opposite, finger-pull concavities 32, one being shown, which may be of limited arcuate extent, i.e. 30. These concavities form interior ridges 33 that serve as finger grips. At the bottom of the interior container 29 is a series of apertures 24, serving for fluid communication.
The object and purpose for the inclusion of container 29 is to provide a receptacle for receiving dry ice, this so that the dry ice may be suspended from the bottom B of the inner container shell 11. Accordingly, the dry ice is prevented from freezing at the bottom of the container so as to otherwise cause difficulty perhaps in either cleaning the container or perhaps in chancing a cracking of the container at this point, owing to the relative coldness of dry ice.
When a sufficient amount of the beverage such as root beer is withdrawn from the container as by use of valve 28, then the user may simply remove the lid and insert his hands so as to raise the container 29 upwardly and outwardly, by the user simply curling his fingers over the plurality of ridges 33 used. While one ridge 33 is shown in FIG. 4 it will be understood that there will be another ridge generally disposed on the opposite side of the container.
What the present invention supplies, therefore, is a new and improved container having relief valve means to relieve excess gaseous pressure within the container, as may be generated by the inclusion of dry ice within the beverage container.
Another advantage is an interior receptacle for dry ice which is completely submerged within the beverage being mixed and yet which can be withdrawn without the use of bails, hooked implements, and so forth. The container is tapered and dimensioned such that the botspaced substantially: above-the bottom B of the outer container, so that any dry ice included or dropped into the interior container will not engage directly, the bottom of the overall=container. .Where the containerheight of interior container 29 approximates .6 inches, by way of example, then the'upper, edge 31 should be dimensioned to have an outer diameter essentially equivalent to the interior diameter of the outer con tainer about 8 inches above the bottom, B of FIG. 4.
While particular embodiments of the invention have been shown and described, it will be obvious to those skilled in the. art the various changes and modifications which may be made without departing from the essential features of the present invention and, therefore, the,
aim in the appended claims is to cover all such changes and modifications as fall within the true spirit and scope of the invention.
l. A beverage container including, in combination,
