CLOSURE FOR CONTAINERS Filed April 25, 1928 INVENTOR Grcggston L. Ohmart ATTORNEY Patented June 17, 1930 I v UNITED STA TES PATENT OFFICE.
emvsron L. onmmr, or DETROIT, MICHIGAN CLOSURE FOR CONTAINERS Application filed April 23,
This invention relates to a closure for containers, and has special reference to a closure adapted for the so-called collapsible tube.
It is appreciated that efforts have been heretofore made to provide a closure of this 7 manufacturing at costs which are such as to render the article commercially practical.
' It must also be ofsuch construction to maintain an effective positive seal for the contents of the container over a long'period of time. Some of the heretofore proposed structures are too expensive to ma e, while-others do not effect a seal which issuificient to maintain the original condition ofthe contents over a long period of time. i
The present invention aims to provide an improved closure which possesses these es-" sential features. The construction is simbe had so that the contents will not deteriorate.
y In the accom ani ing drawings:
. Fi ..1 is a si e e e ational view'of a collapsible tube showing the closure applied thereto.
Fig. 2 is a vertical sectional view taken through the closure construction.
' Figs. 3 and 4 are sectional views taken res 'ective'ly on line 3-3 and 44 of Fig. 2.-
ig. 5 isa side elevation, somewhat enlarged, showing the closure in open position.
1928. serial No. 272,068.
The drawings depict a collapsible tube 1 provided with a neck 2 for the discharge of the contents.- This neck of the tube may be formedso as to act as one of the members of the closure, and for this purpose is provided with a circular shoulder 3 having a project ingstud 4. Above the central shoulder this element is shaped for receiving a cooperating part of the closure and for this purpose it may be advantageously of a cone shape.
The extreme end is provided with a stud 5.
The construction thus described may be suit ably formed ofpne integral piece of metal, but if desirable the projectione and stud 5 may be of separate pieces. i
A discharge passageway 6 extends through theneck, and through one side of the cone shaped portion, is a discharge outlet 7. Fiterably cork, and then fitted over the cork is a hollow conical shaped member 9 which may be provided with a knurled shoulder "ted over the conical part is a material 8, pref- 10. I This member 9 fits over the shoulder 3 and is provided with a channel 11 for receiving the projection 4. It is to be noted that the rotative movements of the member 9 are thus limited by the projection 4.
Both the cork element and the rotating element 9 have openings 7 and 7 respectively, for cooperation with the discharge opening 7. When the, rotative element is turned to one extreme end of its movement the openings in the members are aligned so that the contents of the tube may be discharged through the aligned openings, and when the rotative element is turned to the other extreme end of its movement the discharge 0 ening 7 is closed. The metal around the opening 7 can be'cham-. fered away as shown'at12, so that no substan'tial recess occurs for holding some of the discharged contents after the closure has been moved to close the discharge outlets.
The extreme end of the member 9 is provided with an aperture through which the stud 5 projects and after the parts have been assembled the stud 5 is turned-over to form a head 15 for holding the parts assembled.
This may be accomplished by spinning over the metal or riveting it. In some of the claims appended hereto the term riveting is used to mean broadly anykind of turning over method. This turningover of the stud 5 is accomplished in such a manner as to tie the assembly together tightly so that the cork insert is compressed. In other words, when the stud 5 is turned over, the rotative element is forced down tightly against the cork so that the cork is under compression. The cork insert is placed upon the conical neck so that its opening 7 is inalignment with the opening 7. This relative position is a permanent one and for the purpose of assurroughness provided by merely not finishing off the conical surface smoothly, as for example, a polishing action.
The manner in which the construction performs is not" diflicult to understand. When the container is filled at a factory, the rotative element 9 is positioned so that its opening is out of alignment with the openings in the neck portion of the top of the cork. In
I this position an elfective seal is provided so that the tube can be held in stock as above,
pointed out for an indefinite period. Due to the fact that the insert of cork is under compression, it tightly abuts against both the conical portion of the neck and the interior of the rotatable member, so that an effective air tight seal is provided. In use, the user merely turns the rotatable element for discharging a quantity of the contents, and then turns it back to disalign the openings.
The preferred shape which the parts take, is a shape shown substantially by the drawings. However, it is well within the invention to vary the angularity or steepness of the cone and in fact, the parts could be shaped so that instead of a conical formation, a substantially circular or even a flat construction would be had. However with the conical shape as shown, a very nice action is found to be had, in the compression of the cork.
The insert member is preferably of cork, although some other sealing substance could be used in place of the cork such as a'rubber composition, butit is preferable that the substance be more or less compressible or elastic sothat the sealing insert can be compressed to efl'ect the positive air tight seal.
This closure can be made as shown and described as being integral with a container, or-it can be made as a separate manufactured article adapted to be screw threaded or otherwise secured onto the customary screw thread ed neck of any commercial container or collapsible tube. Claims: 1. A closure for collapsible tubes or the like, comprising amember having a discharge opening, a cap mounted on said member and member, and which is held under compres-'- sion to seal the closure, said insert having an opening for alignment with the first mentioned openings.
