2 Claims.

My invention relates to a catsup dispenser and has for an object to provide means whereby catsup may be dispensed in an orderly manner.

A further object of my invention is to provide means whereby catsup or other heavy bodied semi-liquid material may be forcibly dispensed. Other features and advantages will become more readily apparent from the following de-' In the above drawings as well as in the specification to follow, the same characters of reference indicate the same parts throughout.

My invention consists of a container 10, havinng slots H and 12, in its upper flanged edge I3, to receive the retainer pins l4 and I5, projectable into the opposite slots l6 and H, of a closure cap ll. This cap is provided with a flared recess [8, in its center to receive the fixed flange I9, on an externally threaded tube 20, which extends through the recess I8, and its extension bore 2 I.

details and parts such as come within the pur-- view of the invention claimed may be resorted to, in actual practice, if desired.

Having now described my inventionthat which I claim as new and desire to procure by Letters Patent is: r 1. A liquid container and dispenser comprismg a casing having an open end and a closed end, a centrally disposed bearing seat on the closed end, an exteriorly threaded tube rotatably seated at its lower end in the bearing seat and having radial openings formed adjacent to said end for communicating the tube with the casing, a piston on said tube and actuated thereby for forcing liquid in the casing up through the tube, a closure member seated in said open end and formed with a central opening for receiving the upper end of the tube, said opening being counterbored on the under side and an annular shoulder on said tube positioned in the counterbore to prevent withdrawal of the tube, radial extensions on the upper extending end of the tube resting on the closure member, and radial locking plungers slidably carried by the open end of the casing for frictional locking engagement in radial openings formed in the closure member.

2. In a liquid dispenser, a casing having an open end, a tube rotatably journaled in the casing, a piston actuated by the tube, a closure member for said open end, said closure member having a central opening for receiving the tube, said The bottom wall 22, of the container I I1, is

provided with a central enlargement 23, provided with a recess 24, in which seats the terminal 25, of the tube 20. The lower end 26, of said tube is provided with opposing slots or apertures 26 and 27 through which the contents of the container is dispensed. The upper end 28, of the tube is screw-threaded to receive a dispensing spout 29, or a closure cap (not shown). Secured to the opposing sides of the tube end 28, are a pair of wings 30 and 3|, forming hand-holds. Threaded upon the tube within the container is a piston 32, which through relative rotation of the container and the tube will be slowly driven toward the bottom wall 22, forcing the contents of the container out through the apertures 26 and 21, through the tube and out of the spout 29. The user holds the wings 30 and 3|, with one hand and turns the container 10, with the other hand until a desired amount of catsup or other contents of the container has been dispensed.

It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after considering the description in connection with the drawings. Therefore, a more lengthy description is regarded as unnecessary.

Changes in shape, size and rearrangement of opening being counterbored on the underside of the closure member, a lateral shoulder on said tube positioned in the counterbore to prevent withdrawal of the tube, said closure member having an annular shoulder on its upper edge and an annular seat formed in the upper inner edge of the open end of the casing for receiving said shoulder, radial plungers slidably carried by the open end and said closure member having radial recesses for frictionally receiving the plungers whereby the closure member is locked in the open end and held against rotation therein.
