end portion of the conduit and said ribs extend further than the
remainder of the end portion whereby the cap is spaced therefrom,
providing a plurality of entry paths into the well for the liquid
from the container.
4. A dispenser cup as defined in claim 3 and further including a
flexible tube attached to the portion of the conduit in the
container, said tube extending into the liquid in the
container.
5. A dispenser cup as defined in claim 4 wherein the skirt has
thread portions formed thereon adapted to connect with mating
threads on the wide mouth of the container.
Description
BACKGROUND OF THE INVENTION
This invention relates to dispensers and more particularly
dispensers which are adapted to be used with flexible wall
containers.
Flexible wall containers with dispensers have been used for many
purposes. One use of such containers and dispensers has been in the
dairy industry in connection with disease prevention. In that
industry one method of disease prevention is carried out by means
of teat dipping with a bacterial control solution, particularly for
the prevention of mastitis in dairy cows. The dispensers used for
such dipping usually have a well in the upper portion of the
dispenser and some means for forcing liquid from the container into
the well. In order for such a dispenser to work properly it is
necessary that several criteria be met. First, the dispenser must
be inexpensive to manufacture in order that it may be provided to
the user at a minimum of cost; second, the dispenser must be
designed to permit the insertion of the teat into the well quickly
and easily so that the dipping operation can be carried out
efficiently; and, finally, the dispenser must be designed so that
the treating solution will not be easily spilled or lost in
transferring it from the container to the dispenser.
Accordingly, it is an object of the present invention to meet each
of these criteria. Therefore, the present invention provides a
dispenser which has the unique construction of providing adequate
space for dipping as well as sure means of conducting the liquid
from the container into the well portion of the dispenser.
This is carried out by means of a dispenser which is adapted to be
substantially molded as a single piece with only a semi-closure cap
added to provide the complete dispenser combination. By the present
invention liquid is forced by squeeze pressure from the container
through a conduit and then it is directed downwardly along the
outer portion of the conduit into a well formed with tapered walls.
Thus, it will be seen that the present invention provides a simple
arrangement whereby the path of the fluid from the container to the
well of the dispenser is controlled and precisely directed at all
times.
DESCRIPTION OF THE DRAWINGS:
FIG. 1 is a perspective view of the dispenser and container
combination of the present invention;
FIG. 2 is a sectional side view of the dispenser and container
combination of the present invention showing a teat inserted into
the well of the dispenser; and
FIG. 3 is a partially fragmentary perspective view of the upper
portion of the conduit of the dispenser of the present
invention.
DESCRIPTION OF THE ILLUSTRATED EMBODIMENT:
Referring to the drawings and to FIGS. 1 and 2 in particular, a
container 10 is shown in combination with a dispenser 12. It will
be noted that the container 10 which is of the flexible wall type
has a low profile. Such a container has an advantage in teat
dipping since the container is not cumbersome and it is easily
inserted under the udder of a cow to immerse the teat in the
dispenser's well.
In the container 10 the dipping liquid 14 is contained and this
liquid may be of any desired kind, depending upon the purpose for
which it is intended to be used. The container 10 has a bottom wall
16 and flexible side walls 18. At the upper extent of the side
walls 18 a shoulder 20 is provided which connects to the neck 22 of
the container. The neck 22 which has a series of threads molded on
its outer portion, surrounds a wide, open mouth 26.
The dispenser 12 which is shown connected to the container 10 in
the illustrated embodiment has an open well 28 on its top surface.
Surrounding the well 28 is an annular top wall 30 and depending
from this top wall 30 is a skirt 32 which has a plurality of
threads 34 on its inner surface. The threads 34 on skirt 32 engage
the threads 24 on neck 22 of the container. Thus, the dispenser is
readily joined and attached to the container.
The well 28 has an inwardly tapered side wall 36 which joins with a
concave bottom wall 38. Integrally molded into the dispenser 12 and
extending through the side wall 36 is a conduit 40. The conduit 40
in the illustrated embodiment is aligned substantially vertically
with, but eccentrically of, the center longitudinal axis "A" of the
well 28.
The conduit 40 extends from the inner portion of the container 10
and into the well 28. The lower conduit portion 42 extending into
the container 10 has connected to it a flexible tube 44 which is of
sufficient length to be adjacent to the bottom wall 16.
A continuous bore is provided through the conduit 40.
As shown in FIG. 3 the upper conduit portion 48 has a plurality of
recess portions 50 formed on its outer surface and these recessed
portions are bounded by a plurality of ribs 52. The rib ends 54
extend beyond the top 56 of the remainder of the upper portion 48.
Finally a cap 58 is fitted over the upper portion 48 and embraces
the ribs 52. The rib ends 54 space the cap 58 above the top 56,
thus, completing a path for the liquid 14 from the interior of the
container 10 into the well 28 of the dispenser. This path is
through the flexible tube 44 into the bore 46 of conduit 40, over
the top 56 and between the ribs 52, the upward travel of the liquid
being limited by the upper portion of the cap 58. Because of the
particular construction of the conduit 40 and the cap 58, the
liquid which is pumped by outside pressure against the flexible
walls 18 moves upwardly and then it is deflected downwardly
insuring that it will be deposited into the well 28.
In actual operation by merely squeezing the walls 18 any desired
quantity of a liquid 14 can be placed in the well 28 along the
circuitous path which has been described.
It will be seen that the present invention provides a simple
dispenser with a sure means of directing the liquid into the well
where it can be used, as shown in the illustrated embodiment for
teat dipping.
The flexible wall container may be made of any suitable plastic
material such as polyethylene. The dispenser may also be made of
any desired plastic material but preferably it is of a rigid or at
least a semi-rigid construction.
