DISPENSING RECEPTACLE FOR ADHESIVES Filed Sept. 23, 1927 Patented Oct. 8, 1929 rar 'rY oFIcE JOHN E. R. HAYES, OF MELROSE, MASSACHUSETTS, ASSIGNOR TO TI-IE CARTERS INK COMPANY, OF CAMBRIDGE, MASSACHUSETTS, A CORPORATION OF MASSACHUSETTS DISPENSING RECEPTACIE FOR ADI'IIESIV'IESy Appncanon fusa september 23, 1927. sei-iai No. 221,585.
The invention relates to an improvement in dispensing receptacles for adhesives especially mucilage. The present receptacle is one of that type which is substantially airtight and is provided with a valve-controlled port or opening through which the mucilage may be dispensed on opening the valve by pressure applied to it Jfrom outside the receptacle, and one obj ect of the invention is to provide avery .simple means for retaining this valve. A further object of the invention is to provide means whereby air may be admitted to the interior of the receptacle at the same time that the mucilage is being dispensed therefrom on opening the valve.
The invention can bestl be seen and understood by reference to the drawings in which- Figure l is a side elevation of the dispensing receptacle.
Fig. 2 is a cross vertical section of the head of the receptacle with attachedcap, the conv tained spring` being shown in front elevation.
Fig. Sis a vertical cross section like that of Fig. 2, but taken on a line substantially at right angles to the line ot the cross section ot Fig. 2.
Fig. 4 is a plan of the receptacle, and
Fig. 5 is a view mainly in side elevation and partly in section showing one method of using the recept-acle.
l represents the body of the receptacle consisting preferably of a bottle of any common type. Attached to the top open end oi this bottle closing it is a cap 2. This cap comprises a crown or dome 3, a rim 4l and a downturned lange 5. The rim l lits against the top end of the bottle. The flange 5 is the means by which the cap is secured to the top end of the bottle, the flange being attached thereto in any suitablefmanner and preferably by providing the flange with indentations 6 which :fit within sockets 7 formed in the wall of the bottle.
The crown 3 of the cap is provided in its sides with port openings 8 oppositely arranged. These openings are each preferably formed i n flattened portions 9 on opposite sides of the crown and lie below the top thereof. Each of these openings is controlled by a valve 10 which projects through the opening to protrude beyond the outer 'ace of the. dome when the valve is closed, the valve being provided on its inner end with a skirt ll which seats against the inner edge of the dome around the opening in it or closing the opening.
As just explained, there are two openings and two valves each valve controlling an opening. The valves are both held normally closed and at the same time yieldingly held so that either valve may be opened by compressing the protruding end thereof against an eX- terior object thereby unseating and opening the valve by means of a bent spring l2 common to both. The ends of the spring areseated in the respective valves, the body of the spring lying` interposed and tensioned between them, the spring holding in place by its own tension. curved spring substantially as shown with body lying pendent within the cavity of the dome.
In operation either valve may be opened by-pressing it against an object to which the mucilage is to be applied, the eect of such pressure being to open the valve and allow the'mucilage to escape. The elasticity of the spring permits such opening and when the pressure. is relieved the valve will immediately be returned to a closed position by the'spring.y
The advantage of using two valves resides not only in that one valve provides a seating or mounting for the end of the spring which retains the other valve, but also in the fact that when onefvalve is being opened for dispensing mucilage through the opening controlled by it, the other valve may also be opened by pressure applied to it by the linger of the operator, thereby allowing air to enter the chamber-ot the bottle and resulting in a freer flow of mucilage as may be desired. In ordinary use itwill be unnecessary to open the second valve for admitting air, but in cases where a considerable amount of muoilage is desired then air may be admitted fo obtaining an increased flow.
The arrangement of the valves permits of the cap being provided with a spreading surface lying between and above the valves and The spring is preferably a a dome provided with separate port openingsV therein, outwardly closing valves controlling said openings, and a bent spring mounted upon and tensioned between said valves` whereby the spring will be held in place by its own tension and the valves in a normally closed position with permitted opening of either, or both simultaneously.
2. In a dispensing receptacle of the 'type specified, the combination comprising the body of the receptacle, a cap closing it having a dome provided with separate port'openings therein oppositely arranged, outwardly closing valves controlling said openings and with extension therethrough when closed, a bent spring tensioned between said valves with ends seated within said valves respectively whereby the spring will be retained by its own tension and the valves in a normally closed position with permitted opening.
3. In a dispensing receptacle or` the type speoied, the combination comprising the body of the receptacle, a cap closing it having a dome provided with port openings in the opposite side thereof, and a top spreading surface lying between said openings, outwardly Closing valves controlling said openlngs, and a bent Vspring mounted upon and tensioned between said valves whereby the springlwill be held in place by its own ten-V sion and the valves normally closed with permitted opening. Y
4. In a dispensing receptacle of the type specified, the combination comprising the body of' the receptacle, a cap Closing it having a dome with a port opening in the side thereof and a sprin(T seating on the dome oppositely arranged with relation. to said opening, an' outwardly closing valve controlling said opening, and a bent spring tensioned between said valve and said seating on the dome, one end of the spring being mounted onsaid valve and the other end of the spring within said spring seating on the dome whereby the spring will be held in place by its own tension and the valve in a normally closed position with permitted opening.
5. In a dispensing receptacle of the type specified, the combination comprising the body of the receptacle, a cap Closing it having a dome with a port opening in the side thereof and a spring seating on the dome oppositely arranged with relation to said opening, anV
outwardly Closing valve Controlling said opening, with extension through said openmg when closed, a bent spring tensioned between said valve and said spring seating on the dome, one end of the spring being seated withinsaid valve and the other end of the spring within said spring seating on the dome whereby the spring will be retained by its own tension and the valve in a normally closed position with permitted opening.
