3 Claims, 3 Drawing Figures CONTAINER WITH REMOVABLE IPUMIP This application is a continuation of application Ser. No. 42,418 filed June I, 1970, now abandoned.
This invention relates to improvements in the dispensing of materials from containers and, more particularly, to a container having an external pump releasably attached thereto.
In dispensing milk or other liquid food products from containers, it is oftentimes desirable to draw out a predetermined volume of the container contents so as to be able to fill glasses, cups and the like which are limited in size and can contain only a limited volume of liquid. It is also desirable that a suitable pump be provided for such a container so as to be able to dispense a predetermined volume of the container contents for each stroke of the pump and to permit the pump to be mounted on the container so that it does not extend into the container. This latter feature assures that the predetermined volume of the container contents can be dispensed by the pump without requiring a relatively long pump inasmuch as the pump can be larger than the opening in the container tip and thereby be made of a size sufficient to pump the predetermined volume. Also, by releasably connecting the pump to the container, the pump can be cleaned and reused after the container has been emptied.
The present invention is directed to the combination of a container having an open top and a pump releasably connected to the container wherein the pump is disposed externally of the container and has a size greater than the opening so that the pump need not extend into the container and upwardly therefrom through a relatively long distance. This feature assures that the pump chamber can be of a size sufficient to permit a predetermined volume of the material in the container to be dispensed therefrom for each stroke of the pump. To this end, the pump is provided with a structure on its lower end for releasably attaching it to the container at the open top thereof. Also, the pump has a tube which extends into the container so as to draw out the contents therein each time the pump is actuated. The container can be of any suitable construction, such as a glass jar or a disposable, plastic-coated paper container of the type used for milk products. The pump can be of simple construction and can be readily secured to and removed from the container. Also, it can be formed from parts which are readily separated from each other and quickly reassembled to allow for frequent cleaning.
The primary object of this invention is to provide a container having an open top and a pump releasably connected to the container in communication with the open top wherein the pump is disposed externally of the container and is larger in size than the open top so as to assure that a predetermined volume of material can be pumped out of the container for each stroke of the pump without the need for a relatively long pump of the type which extends into the container and upwardly therefrom through a relatively long distance.
Another object of this invention is to provide a container and pump combination of the type described wherein the pump has means thereon for making a releasable connection with the container in surrounding relationship to the open top thereof and the pump can be quickly assembled and disassembled so that it can be frequently cleaned to thereby render it suitable for use in dispensing food products from a container.
Other objects of this invention will become apparent as the following specification progresses, reference being had to the accompanying drawing for an illustration of the invention.
In the drawing:
FIG. I is a perspective view of a container and pump combination forming one embodiment of the invention;
FIG. 2 is an enlarged cross-sectional view of a portion of the combination of FIG. I; and
FIG. 3 is a fragmentary side elevational view of a second embodiment of the combination.
The first embodiment of the invention is shown in FIGS. l and 2 and includes a container 10, a pump 12 and a means 14 on the pump for releasably securing the pump to the container adjacent to the open top 16 thereof. The container comprises a jar of glass or other suitable material, the jar having a neck 18 which terminates at the open top 16 and, for purposes of illustration only, is of a reduced cross section relative to the larger portion of the jar. The outer surface of the neck is provided with the threads to threadably receive a lid to close the jar. Other jar configurations can be used as desired.
A circular piston 32 is disposed within housing 20 and slidably engages the inner surface 34 of sidewall 23, whereby the piston can move upwardly and downwardly within the chamber enclosed by the sidewall. A shaft 36 is coupled to the center of the piston and extends upwardly therefrom through a hole 38 and a cap 39 is removably mounted on the upper end of housing 20. The shaft is shiftable relative to the cap so that piston 32 can be manually raised and lowered. The cap can be provided with threads or other structure which permits it to be releasably connected to the sidewall 23 which allows quick disassembly of the pump for cleanmg.
A nozzle 40 is removably connected to the upper end of shaft 36. To this end, nozzle 40 has a sleeve 42 which slides on to the upper end of the shaft and a laterally projecting section 44 is integral with sleeve 42. Section 44 has a fluid passage 46 therethrough which communicates with a space 48 formed in nozzle 40 adjacent to the upper end of shaft 36. Nozzle 40 has an open outer end 41, whereby fluid can exit therefrom. A ball valve 52 is disposed within space 48 for closing the upper end of passage 37. To this end, shaft 36 has a concave seat 54 for ball valve 52.
Connecting means 14 includes an annular skirt 56 rigidly connected to sidewall 23 and extending downwardly therefrom in surrounding relation to extension 24. Skirt 56 is adapted to be threadably connected with neck I8 whereby the container and the pump can be coupled together.
In operation, pump 12 is assembled in the manner shown in FIG. 2. It will first be connected by means of skirt 56 to container with tube 30 extending into the container. The pump and the container will then form the dispensing unit.
The contents of the container are drawn out of the same by lifting nozzle 40 to cause piston 32 to rise within the space defined by sidewall 23. When this occurs, a suction is created in the region below the piston and the container contents rise in tube 30 and unseat ball valve 28 so that the contents can flow into the region below the piston as it continues to rise. At the top of its stroke the pump is actuated by forcing nozzle downwardly. This causes the liquid below the piston to rise in passage 37 and to cause ball valve 28 to close the upper end of extension 24. As the liquid rises in passage 37, it unseats ball valve 52, flows into space 48, through passage 46, and out the same through open end 40. The pump is again charged with liquid from the container by moving nozzle 40 and thereby piston 32 in the manner described above. Each time the pump is actuated, it dispenses a predetermined volume of liquid until the container is emptied.
When the container is emptied, the pump can be removed therefrom and disassembled for cleaning. Sleeve 42 can be removed form shaft 36, cap 39 can be separated form the pump housing, and tube 30 can be separated from extension 24. All of these parts can then be cleaned individually and reassembled, whereupon the pump is ready for use again with a full container.
FIG. 3 illustrates the use of another type of container as a part of the combination of this invention. To this end, a container 60 is provided, the container being of the disposable type conventionally used for containing milkproducts. lt includes four walls and a top having a pair of sloping top sections which terminate at a centrally disposed, upwardly extending seal extension 62. Pump 12 is removably connected to container 60 by a suitable attachment 64 which has a tubular neck 66 adapted to be aligned with a hole in the top of the container when the attachment is releasably secured in any suitable manner to seal extension 62. Neck 66 is provided with an annular, upright projection 68 which is threadably connected to skirt 56 to interconnect pump 12 and neck 66.
