Y. KAPLAN ETAL 81 DISPENSING CONTAINERS FOR LIQUIDS Filed Dec. '7, 195

HAROLD M Ross .A' OR EV United States Patent DISPENSING CONTAINERS FOR LIQUIDS Yale Kaplan, West Hartford, Conn., and Harold M. Ross, Plainfield, N. J.

Application December 7, 1954, Serial No. 473,523 2 Claims. (Cl. 222-107) This invention relates to flexible dispensing containers for limited amounts of liquids, the containers being adapted for shipment in sealed condition and, after tearing off a strip along one end, may be used to dispense the liquid by the application of pressure.

This application is a continuation in part of Ser. No. 303,661 filed August 11, 1952.

A primary object of the invention is to provide a container for sauce or syrup, the quantity held by the container being suflicient for a single serving and the flow from the container being effected by squeezing or compressing the container; the container being so constructed and arranged that, when pressure is released, the flow of fluid will stop and any possible leakage will be prevented. Repeated squeezing will dispense successive small amounts of the fluid until the container is empty, when the container may be discarded.

Another object of the invention is to form the container from thin plastic material by sealing two sides and an end of the container, and, after filling the container with the desired quantity of the sauce or syrup, sealing the other end. One of the ends is sealed by a special die which provides a broad sealed portion with a narrow passage extending part way across the broad sealed portion and so constructed and arranged that, when part of said broad sealed portion has been torn away to open the narrow passage, the sauce or syrup may be dispensed by, and only by, squeezing or compressing the container.

These and other objects of the invention will be apparent from the following explanation in connection with the drawings in which Fig. 1 is a perspective view of a flexible container made in accordance with the present invention;

Fig. 2 is a plan view in section of one form of the invention;

Fig. 3 is a plan view in section of a modification of the package shown in Figs. 1 and 2;

Fig. 4 is a plan view in section of another modification, and

Fig. 5 is a plan view in sect-ion of a further modification.

Referring to the drawings in each of the modifications, container is formed of two sheets of plastic material, the shaded areas 11 being sealed together to enclose liquid 12. One of the ends is sealed after filling the container.

Sealed end 13 is a broad area. Narrow passage 14 extends part Way across broad area 13. Crease 15 and notch 16 may facilitate tearing ofi the strip 17 to open passage 14 and permit dispensing the liquid. Passage 14 is tortuous and includes transverse portion 18. Various forms of plastic material of various degrees of transparency, flexibility, thickness, and method of sealing may be used. The containers illustrated and described are shown as being formed of two sheets of material sealed together over the shaded areas. It is obvious that the container could be formed from a single trip of material folded longitudinally, or from a tube flattened and sealed at the ends only. In any case, the containers may be produced with one end left open for filling, and shipped unfilled in flat condition, the unsealed end being sealed after filling.

To dispense the liquid 12, the operator tears off strip 17 to open the end of passage 14, and then applies pressure to liquid 12 by squeezing or compressing the opposite faces of the container. It is obvious that, in any transverse portion 18 of passage 14, the two sheets of material will distort or spring apart when, and only when, pressure is applied, and thus permit the escape of fluid. Upon release of pressure, in any transverse portion 18 of passage 14, the two sheets will tend to return to fiat position and effectively prevent leakage. The tortuous passage 14 with its transverse portion 18 serves as a spring check valve and allows the fluid to flow only by the application of pressure.

As shown in Figs. 2 to 5, the tortuous passage 14 extending from the space Within the container to the crease line 15 may take various forms. In each form of this passage there is a well defined transverse portion 18.

Having thus described the invention, it is apparent that the objects as stated have been attained in a simple and practical manner. It is understood that changes may be made in the structure and in the arrangement of the invention without departing from the spirit or scope of the following claims.

We claim:

1. A flexible non-metallic container for fluids comprising two sheets of plastic material the edges of said sheets being sealed, one of said edges having a broad sealed area, a tortuous passage from within said container extending to an intermediate part of said broad sealed area, said tortuous passage having a substantially transverse portion, said sealed area being severable at an intermediate point to open the outer end of said tortuous passage to permit dispensing said fluid through said tortuous portion and from said passage only when pressure is applied to the opposite sides of said container to force said sheets apart in said transverse portion.

2. A flexible non-metallic container for fluids comprising two sheets of plastic material the edges of said sheets being sealed, one of said edges having a broad sealed area, a passage from within said container to an intermediate part of said broad sealed area, said passage having a substantially transverse portion, said sealed area being severable at an intermediate point to open the outer end of said passage to permit dispensing said fluid through said transverse portion and from said passage when pressure is applied to the opposite sides of said container suflicient to force said sheets apart in said transverse portion, said passage returning to flat condition to prevent leakage when pressure against the sides of the container is released.
