H. A. ALLEN- SANITARY DISPENSER Filed Dec. 4', 1939 ATTORNEYS Patented Nov. 19, 1940 UNITED STATES PATENT OFFICE 2 Claims.
This invention relates to sanitary dispensers and has for an object to provide a dispenser for liquids and semi-liquids such as catsup bottles, bulk oil cans, medicine bottles, molasses cans and other containers, adapted to prevent the contents spilling over and running down the sides of the container after the pouring operation.
A further object is to provide a device of this character essentially comprising an outer tubular member adapted to be inserted into the neck of the container, an inner tubular member mounted concentrically in the outer member by means of radially extending fins, and a' valve slidably mounted on the inner tubular member, the arrangement such that when pouring the contents from the container, due to closing of the valve, the contents can only pass through the inner tubular member and when the container is returned to upright normal position any drip from the inner tubular member may pass back into the container through the open valve.
A further object is to provide a device of this character which will be formed of a few strong simple and durable parts, which will be inexpensive to manufacture, and which will not easily get out of order.
With the above and other objects in view the invention consists of certain novel details of construction and combinations of parts hereinafter fully described and claimed, it being understood that various modifications may be resorted to within the scope of the appended claims without departing from the spirit or sacrificing any of the advantages of the invention.
In the accompanying drawing forming a part of this specification:
Figure 1 is a longitudinal sectional view of the neck of a bottle equipped with a sanitary dispenser constructed in accordance with the invention and showing the dispenser in elevation.
Figure 2 is a longitudinal sectional view of the bottle neck and dispenser.
Figure 3 is a cross sectional view taken on the line 3-3 of Figure 2.
Figure 4 is a longitudinal sectional view of the bottle neck and a portion of the dispenser and showing a cork stopper for the bottle neck and dispenser.
Figure 5 is a bottom plan view of the cork.
Referring now to the drawing in which like characters of reference designate similar parts in the various views, Ill designates the neck of a container such as a catsup bottle. The dispenser comprises an outer tubular member I! equipped at the top with a flange l2 adapted to abut the top edge of the bottle neck. Mounted concentrically in the outer tubular member II is an inner tubular member I3 having fins 14 secured to the inner surface of the outer tubular member in any preferred manner to space the inner tubular member from the outer tubular" member. The lower end of the inner tubular member terminates in a flared flange l5. The inner tubular member extends above and below the outer tubular member.
Slidably mounted on the inner tubular member below the outer tubular member is a washer forming a valve Hi. The washer is preferably formed of rubber and is provided at the bottom with a flared resilient skirt ll. When the bottle is inverted to pouring position the valve closes the space between the two tubular members as shown by dotted lines in Figure 2, and the contents are dispensed through the inner tubular member.
A cork stopper l8 isprovided for sealing the bottle and dispenser when not in use. The stopper is provided with an axial bore 19 which loosely receives the top of the inner tubular member H3. The stopper is provided at the center of the inner wall of the bore with an integral projection 20 of sufficient diameter to snugly fit within the end of the inner tubular member. Thus the cork seals both the dispenser and the neck of the bottle.
In pouring the contents from a bottle equipped with the device, due to closing of the valve, the contents may only pass through the inner tube l3. However, when the bottle is righted any drip from the inner tube may pass back into the bottom through the outer tube and open valve. Due to the flexibility of the skirt ll of the valve, when the bottle is inverted to pouring position a suction will be created against the skirt, then when the bottle is turned upright again that suction will draw the valve down to its open position, assisted by gravity.
From the above description it is thought that the construction and operation of the invention will be fully understood without further explanation.
What is claimed is:
1. A sanitary dispenser for liquids and semiliquids comprising an outer flanged tubular member adapted to be inserted into the neck of a container, an inner tubular member disposed concentrically Within the outer member, fins connecting the inner member with the outer member, said inner member extending above and below the outer member and terminating at the lower end in a flared flange, and a disc valve slidably mounted on the inner member between the and outer member and through the open valve flared flange and the lower end of the outer when the container is restored to normal position. member and adapted. to close the space between 2.
