s. s. FISHMAN CONTAINER Filed July 28,- 1958 CONTAINER Sherman S. Fishman, San Francisco, Calif.
Filed July 28, 1958, Ser. No. 751,529
2 Claims. (Cl. 206- This invention relates to containers and in particular to a new and improved type of container incorporating a water-tight seal between the container body and the cap. It is desirable in the situation where an item which is stored in a liquid which is enclosed in a carrying case suitable to fit in the pocket of a suit or shirt or other article of clothing without stretching or otherwise deforming the cloth or being noticed by another observer to be an object of noticeable bulk, nor should its liquid contents leak out of the container when it is sealed. Such a container would be suitable for measured volumes of liquids or small quantities of medicinal tablets which illustrates the containers usefulness for solids or solid objects immersed in liquids.
In such a device, if it is to be leak-proof, the fit of the cap about the cylindrical body is of such a designed close fit that air is trapped internally as soon as the cap is slightly fitted on in the process of closure. This is more easily obtained by the judicious use of materials such as alathon, nylon, tygon and the like which have the further advantage of the physical property of excellent water resistance ratings and elongation and recovery. The internally trapped air is accounted for by providing a vent in the cap, and the provision for sealing the vent upon proper closure of the cap is provided for by a shaped papilla which is a part of the container body and abuts against the vent in the cap. Alternatively, the vent can be placed on the lateral wall of the cap so that it will abut against the outside surface of the container body until most of the trapped air has been relieved, and any remaining air is forced out of the vent by means of pressure created by forcing the cap closed and therefore sealed.
Accordingly, it is the main object of this invention to provide a novel container which can be carried in the pocket without leaking any of its liquid contents by utilizing the new and improved leak-proof seals.
The above and still further objects and advantages of the present invention will become apparent upon consideration of the following detailed description of a specific embodiment thereof, especially when taken in conjunction with the accompanying drawing herein:
The character of the invention is illustrated by:
Figure 1 is a side view of the container which has a base, dual body compartments and caps.
Figure 2 is a cross section of Figure 1.
Figure 3 is a top view of Figure 1.
Figure 4 is a top view of a cap.
Figure 5 is a cutaway view of Figure 1.
Figure 6 is a side view of a cap.
Referring in detail to the drawing in which the same 7 2,948,387 Patented Aug. 9, 1960 reference characters indicate like elements, in the different views, Figure 1 illustrates a container which comprises a base 1 and a body 2 and a cap 3. Figure 2 is a cross section along the line 7-7 of Figure 3 and shows the base 1 and the body 2 to be constructed of one unit. The cavity 4 provides for the storage of liquids or solids and the papilla 5 is seen to be a small prominence protruding into the cavity and which serves the particular function of abutting against the vent 6 when the cap 3 is closed as is further illustrated in the Figure 5 wherein the seal is made by the vent 6 and the papilla 5. Figure 3 is a top view of the container showing the prominence 5 in relation to the cavity 4 and the body wall 2. Figure 4 is a top view of the cap 3 showing the vent 6 in its relative position. Figure 5 is a cutaway view of an assembled container. Figure 6 is a side view of a cap 8 showing the vent 9 located on the lateral wall which is an alternative position for the vent which when it abuts against the body wall :of the container makes a suitable liquid and air seal.
Having described my invention of a new and improved container, it will be readily appreciated by one skilled in this art that I have utilized the properties of capill'arity combined with the water resistance and resiliency of the container material which is from the group of substances based on acrylate resin, methacrylate resin, epoxy resin, ethylene resin, fluoroethylene resin, isocyanate resin, polystyrene resin, polyvinyl chloride resin, polyvinyl acetate resin, fur-an resin, coumarone resin, polyamide resin, polychloroprene, butadiene-styrene, butadiene-acrylonitrile, isoprene-styrene, urea-formaldehyde resin, phenol-formaldehyde resin, melamine-formaldehyde resin, cellulose-acetate-butyrate, cellulose nitrate and the like to devise a container which is uniquely sealed against fluid leakage and I have shown the embodiment of this container as illustrated best in Figure 5 wherein fluid in which an item, as for instance a single contact lens, is stored in separate compartments and immersed in fluid. In this instance the container has two chambers to provide separate compartments for a right lens and a left lens.
Modifications of this invention will occur to those skilled in this art and it is to be understood, therefore, that this invention is not limited to the particular embodiment disclosed but that it is intended to cover all modifications which are within the true spirit and scope of this invention.
What I claim as new and desire to secure by Letters Patent of the United States is:
1. A container for contact lenses made of water resistant resilient solid synthetic resin consisting of a base plate having two upright cylindrical bodies afiixed to it so placed that one is separated from the other, each of said upright bodies having a hemispherical depression in its top surface, said depressions having diameters less than the diameter of the cylindrical upright body and being concentric therewith, thus forming a wall between the periphery of the depression and the periphery of the cylindrical body, each of said cylindrical bodies having a cap adapted to cover and close said depression; each of said caps having an air vent so positioned that it is in contact with said wall when the cap is seated.
2. container for contact lenses made of water resistant resilient solid synthetic resin consisting of a base plate having two upright cylindrical bodies aflixed to it so placed that one is separated from the other, each of said upright bodies having a hemispherical depression on its top surface, each of said cylinders having a small shelf-like projection into each of the said hemispherical depressions, said shelf being level with the uppermost part 5 of said cylindrical body and a cap for each cylindrical body adapted to cover said depression, said cap having an air vent so positioned that said cap may be rotated to close the air vent by bringing it into contact with the 10 shelf-like projection.
