BEVERAGE CONTAINER
Abstract
A beverage container including a container and a cover member
therefor. A plurality of mixing vanes are formed integrally with
the bottom face of the cover member and extend radially outwardly
from a central hub portion to outer end portions. The vanes are
tapered from a relatively narrow width at the hub portion to a
greater width at the end portions. The vanes serve to impart a
swirling action to liquid in the container when the container is
moved rapidly up and down.

Claims
I claim:
1. A beverage container comprising:
a container having an interior surface which tapers outwardly at
the top portion thereof:
a cover member having a bottom face and side walls which curve
upwardly and outwardly from said bottom face, with the curve of
said side wall conforming to the interior taper of said container
to provide a snug fit between said cover and said container, said
cover being in the form of a cup-shaped container which may be
graduated and used for measuring liquid to be blended or mixed in
said container, a plurality of mixing vanes formed integrally with
and extending from the bottom face of said cover member, said vanes
extending radially outwardly from a central hub portion to outer
end portions with the lower edges of said vanes tapering downwardly
from said hub portion and with the upper edges of said vanes
tapering upwardly from said hub portion.
2. The container according to claim 1 in which said mixing vanes
curve as they extend from said hub portion to the outer end
portions thereof.
Description
BACKGROUND OF INVENTION
This invention relates to a beverage container having internal
means for imparting a swirling action to liquid therein upon up and
down movement of the container. The object of this invention is to
provide such a mixing container which is both effective and of
simple construction.
SUMMARY OF INVENTION
A beverage container comprising a container and cover member
adapted for sealing installation in the container to provide a
sealed compartment inside the container. A plurality of mixing
vanes are mounted at one end of the compartment. The vanes extend
radially outwardly from a central hub portion to outer end portions
and are tapered from a relatively narrow width at the hub portion
to a greater width at the end portions. In the preferred embodiment
the mixing vanes are formed integrally with the bottom face of the
cover member.
DESCRIPTION OF DRAWINGS
FIG. 1 is a perspective view of a beverage shaker which embodies
the present invention;
FIG. 2 is a sectional view taken along line 2--2 of FIG. 1;
FIG. 3 is a perspective view of the cover member employed in the
beverage shaker of the present invention; and
FIG. 4 is a bottom plan view of the cover member shown in FIG.
3.
DESCRIPTION OF PREFERRED EMBODIMENT
Referring to the drawings in detail, the present invention is
comprised of two basic parts, namely a container 10 and a cover 12
therefor. Container 10 may be of any suitable construction such as
that shown in FIG. 2 wherein a double wall container is provided
having an outer shell 14 and an inner shell 16 separated by air
space 18 to provide good insulation properties. Inner shell 16 is
tapered outwardly at the top portion 20 thereof to snugly
accommodate cover member 12 as best shown in FIG. 2.
The cover member 12 is preferably made in the form of a cup-shaped
stopper having sidewalls 22 which curve upwardly and outwardly. The
cover member is provided with a bottom wall portion 24 which, with
sidewalls 22, form a container which may be graduated and used for
measuring liquids to be blended or mixed in the container.
Viewing the cover member from the bottom, the bottom wall portion
24 has a substantially convex configuration. A plurality of mixing
vanes 26 are formed integrally with the bottom wall portion 24 of
the cover member. Vanes 26 originate at a center hub 28 and curve
radially outwardly therefrom toward the outer periphery of the wall
portion 24. The lower edges 30 of the vanes 26 taper downwardly
from hub 28 and the upper edges 32 taper upwardly from the hub.
Thus, as most clearly shown in FIG. 2 each vane tapers outwardly
from a relatively narrow width at the hub 28 to a greater width at
the ends thereof.
The cover member 12 may be securely installed in the container 10
by simply inserting it to the position shown in FIG. 2 wherein the
curved sidewalls of the cover nest securely within the curved
sidewalls of the inner shell 16. With the cover member installed as
shown in FIG. 2, and with liquid in the container, a thorough
mixing of such liquid is accomplished by an up and down movement of
the container. The shaking of the covered container will cause the
liquid therein to impinge on the vanes 26 which in turn will tend
to induce a swirling action to the liquid to thus facilitate a
thorough mixing and blending of the liquid. As clearly shown in
FIG. 4, the mixing vanes 26 curve outwardly from hub portion 28 in
a clockwise direction. This configuration will induce a
counterclockwise swirling action to the liquid. It will be
appreciated that the vanes could be constructed to curve in just
the opposite direction, in which event they will tend to induce a
clockwise swirling action.
While the mixing vanes 26 in the preferred embodiment are shown
mounted on the bottom face of the cover member 12 it will be
appreciated that a similar mixing action could be attained by
mounting the mixing vanes on the bottom surface of inner container
16.
