DISPENSING CLOSURE CAP FOR CONTAINER HAVING FRANGIBLE' SEALING MEANS Filed Oct. 4, 1965 INVENTORS ALVIN J. PORTER 00IVAD w. MA Til/801V aim, as, drug AT TORNE Y5 United States Patent 3,318,494 DISPENSING CLOSURE CAP FOR CONTAINER HAVING FRANGIBLE SEALING MEANS Alvin J. Porter, Excelsior, and Donald W. Mathison, Minneapolis, Minn., assignors to Product Design & Engineering, Inc., Minneapolis, Minn.

Filed Oct. 4, 1965, Ser. No. 492,802 Claims. (Cl. 222-534) The invention relates broadly to closure caps for containers and more particularly to a dispensing closure cap having frangible sealing means.

Conventional dispensing closure caps include at least one part which may be moved relative to another part in order to obtain a sealing action. One method of such sealing is found in US. Patent No. 2,793,795. While this sealing action is obtained, the sealing accomplished is not positive particularly for containers containing liquids such as lighter fluid and the like.

It is an object of the invention to provide a dispensing closure cap having a valving spout member and a frangible sealing member which is removed by a single movement of the valving spout member, the valving spout member continuing to be operable.

It will not be here attempted to set forth and indicate all of the various objects and advantages incident to the invention, but other objects and advantages will be referred to in or else will become apparent from that which follows.

The invention will appear more clearly from the following detailed description when taken in connection with the accompanying drawings, showing by way of example a preferred embodiment of the inventive idea wherein like numerals refer to like parts throughout.

In the drawings forming part of this application:

FIGURE 1 is a perspective view of the dispensing closure cap of this invention in open position with the frangible sealing member shown as removed.

FIGURE 2 is an exploded perspective view of the cap of FIGURE 1 with the sealing member intact.

FIGURE 3 is a sectional view on the line 44 with the cap in a closed position.

FIGURE 4 is a sectional view on the line 44 of FIG- URE 1.

Referring to the drawings in detail, the dispensing closure cap A includes the base portion formed of the internally threaded annular wall 12 and the circular top wall 13. Formed on the top wall 13 is the extension portion 14 in which is formed a semi-cylindrical cavity 16, which is in alignment with a diameter of the top wall 12. Leading radially from the cavity 16 is the channel 18 which is parallel to the .top 12 and which extends to the edge of the top itself.

The cavity 16 is formed by the semi-circular wall 20 formed in the cap extension portion 14 which terminates in an upper stop shoulder edge 22 and at its lower edge at 24 where it joins the bottom of the channel 18.

Further provided are the pair of spaced wall members 26 and 28 formed in the extension portion 14 which extend from and at right angles to the shoulder 22 and normal to the axis of the semi-cylindrical cavity 16. The wall 26 has formed on the upper edge thereof the semicircular bearing opening 30 which extends slightly greater than 180 and forms the slot 32. The wall 28 is similarly formed with the semi-circular bearing opening 34 which extends slightly greater than 180 and forms the slot 36.

The numeral 38 designates the spout which includes the arm portion 40. The art portion 40 has formed on the lower end thereof the cylindrical base portion 42, and extending axially of the spout base portion 42 are the trun- 3,318,494 Patented May 9, 1967 nions 44 and 46. The base portion 42 has extending radially thereinto the recess 48. Extending longitudinally through the arm portion 40 of the spout 38 and through the base portion 42 is the outlet passageway 50 which bypasses the recess 48.

The wall 20 has extending therethrough the outlet hole 52 which is sealed at its inner end by means of the plug 54. The plug 54 is' attached at its lower end at the entire periphery thereof as at x by a thin frangible connection with the inner surface of the wall .20 in alignment with the outlet hole 52. Thus, with the plug 54 in place, material cannot flow through the spout. Thus leakage is not controlled by the close fit of the base 42 in the cavity 16.

The spout 38 is pivotally mounted on the cap A by forcing the trunnions 44 and 46 thereof through the slots 32 and 36, respectively, into the bearing openings 30 and 34, respectively. The trunnion 44 and 46 are held in the bearing openings 30 and 34, for the openings extend more than and the walls in which the bearing openings are formed are formed of plastic which is slightly deformable.

The base 42 of the spout 38 is forced into place in the positionshown in FIGURE 3 with the plug 54 extending into the recess 48. When the spout 38 is pivotally moved from the position of FIGURE 3 to that of FIGURE 4, the plug 54 is broken away from the wall 20 at connection x by means of the wall portion 56 of the recess 48 contacting and being forced against the plug. The wall portion 56 is substantially normal to the longitudinal axis of the passageway 50. As the plug 54 is severed, it is carried captive from the outlet hole 52 and within the recess 48 by the turning moment of the recess 48 and the wall 56 thereof to a point in line with the channel 18 where the plug 54 is easily removed from the recess. The recess 48 is so positioned relative to the outlet hole 52 that when the recess 48 is in substantial alignment with the channel 18, as in FIGURE 4, the passageway 50 is in alignment with the outlet hole 52 whereby the contents of a container (not shown) attached to cap A can flow outwardly through the spout 38. The cap A is closed by returning the spout 38 to the position of FIGURE 3 without the plug 54.

The invention is not to be understood as restricted to the details set forth since these may be modified within the scope of the appended claims with-out departing from the spirit and scope of the invention.

Having thus described the invention what is claimed as new and desired to be secuerd by Letters Patent is:
