SELF-CLOSING CLOSURE CAP FOR COLLAPSIBLE CONTAINERS Filed May 23, 1957 a ML INVENT OR.
United States Patent SELF-CLOSING CLOSURE CAP FOR COLLAPSELE CONTAINERS ,My invention relates to selfeclosing closure caps for collapsible containers and the like.
One of the objects of my invention is the provision of a closure cap of the foregoing character in which closure of the discharge aperture of the cap is automatically effected when a predetermined quantity of the tube contents has been expressed from the container.
Another object of my invention is the provision of a closure cap of the foregoing character wherein the pres sure of the contents in the container acting on a movable element of the cap structure is utilized for effecting closure of the discharge aperture of said cap.
Other and further objects and advantages of my invention will become apparent from the following description when considered in connection with the accompanying drawings in which Fig. 1 is a vertical cross-sectional view of a closure cap in accordance with my invention, the same being shown in open discharging position.
Fig. 2 is a cross-sectional view, on an enlarged scale, taken substantially on line 22 of Fig. l. I
Fig. 3 is a view similar to Fig. 1 but showing the cap structure in closed position, and
Fig. 4 is an enlarged fragmentary vertical cross-sectional view illustrating structural features in greater detail.
Referring to the drawing, the numeral 5 indicates generally a closure cap structure formed of a first element 6 and second element 7, both elements being in telescoping relation and formed preferably of suitable plastic material, as by injection molding. The element 6 comprises a hollow cylindrical body portion open at the top with a depending flared skirt 8 at the bottom and having internal threads 9 for cooperation with threads of a collapsible container 10, such as a tooth paste tube. A discharge aperture 11 of any suitable shape is provided in the wall of element 6 and immediately above the discharge aperture 11, there is a bafile member 12 integral with the wall. The baflle may be substantially semi-circular in plan, as clearly illustrated in Fig. 2. Substantially diametrically opposite the aperture 11 there is provided, in the wall element 6, a recess 13 for a purpose, as will be hereinafter described.
The second or movable element 7 comprises an inverted cupped member arranged in telescoping relation to the first member 6. The element 7 similarly is provided with a discharge aperture 14 which is adapted to register with the discharge aperture 11 of the element 6, when the elements 6 and 7 are disposed in the relationship illustrated in Fig. 1, corresponding to the open position of the cap. The element 7 is provided with a protuberance 16 and on the inner wall surface thereof, the said protuberance being received within the recess 13 and cooperating therewith to maintain the elements 6 and 7 in a desired relationship, wherein the element 7 is prevented from rotating relative to the element 6 and the respective apertures 11 and 14 are maintained in vertical alinement. The protuberance 16 co-acting with the recess "ice 13 also serves to limit the axial movement of element 7.
When the elements 6 and 7 are in the relationship illustrated in Fig. 1 the apertures 11 and 14 are in registration and provide a discharge opening for expressing the contents from the tube 10. It will be apparent that immediately upon the application of pressure on the tube 10 some of the contents in the tube initially will pass into the cavity of cap 5 and fill the same. Upon continued application of pressure some of the contents will be discharged through the aperturesll and 14. Concurrently, the pressure on the tube will be transmitted to top wall v, 16a of element 7 causing the same to move in an upwardly direction so that .the wall portion of element 7 below aperture 14 is caused toclose off the aperture 11 and thus cut ofi the discharge of contents from the tube. The action is such that a measured quantity of contents is discharged from the tube with each manipulation of the tube as above described. The baflle 12 afiords means for controlling the fiow of contents from the tube through the discharge openings.
If a quantity of contents greater than that normally delivered is desired, the element 7 may be held down as with a finger to retain the apertures 11 and 14 in registration and prevent the element 7 from moving upwardly.
Fig. 3 illustrates the normally closed position of the cap wherein the contents are sealed off from contamination by extraneous foreign matter. In order to effect the discharge of the contents from the tube it is necessary only to press down on element 7 to bring aperture 14 in registration with aperture 11. It Will of course be understood that in such downward movement of element 7 some of the contents within the cavity of the cap will be forced back into the tube. This of course does not in any Way affect the operation of the cap. Pressure on the tube walls will then effect the discharge of the contents in the aforedescribed manner.
Various changes coming within the spirit of my invention may suggest themselves to those skilled in the art. Hence, I do not wish to be limited to the specific embodiment shown and described or uses mentioned, but intend the same to be merely exemplary, the scope of my invention being limited only by the appended claims.
I claim:
1. In combination with a collapsible container a selfclosing closure cap comprising an inner element having a cylindrical body open at both ends and connected at one of said ends to the discharge end of said container, an outer element concentric with said inner element and axially slidable relative thereto, said outer element being closed at the top, each of said elements having a side aperture, said apertures being in registration when said outer element is in retracted position, a bafile in said inner element above the aperture thereof, said apertures when in registration permitting the discharge of contents from said container when the same is compressed, the pressure on said container during such compression being transmitted to said outer element to move the same axially to close off the aperture of said inner element and thereby prevent the discharge of contents from said container.
2. In combination with a collapsible container a selfclosing closure cap comprising an inner tubular element, an outer tubular element movable in telescoping relation thereto, said outer element being closed at the upper end, said inner element-being open at both ends and connected at one of said ends to the discharge end of said container, each of said elements having a side aperture, said apertures being in registration when said outer element is in retracted position, the said apertures when in registration alfording discharge of the container contents when the container is compressed, said outer 3 element when said container is compressed being caused to move axially and automatically to cut ofi the discharge of contents from said container at a predetermined point so as to provide a measured quantity of contents.
3. In combination with a collapsible container a selfclosing closure cap comprising an inner'tu-bular element, an outer tubular element movable in telescoping relation thereto, said outer element being closed at the upper end, said inner element being open at both ends and connected at one of said ends to the discharge end of said container, each of said elements having a side aperture, said apertures being in registration when said outer element is in retracted position, the said apertures when in registration affording discharge of the container contents when the container is compressed, said outer element when said container is compressed being caused to move 4 axially and automatically to cut off the discharge of the contents from said container at a predetermined point so as to provide a measured quantity of contents, and
means for limiting the axial movement of Said outer element. v
