TUIIBE CO'NTAINER AND CLOSURE THEREFOR. I

Further, with the channel Gland the projection 7 arranged in relation with one another as described and shown, when the pass sage between the openings 4 and 8 is closed the valvemember will be moved to bring the channel downwardly into the depression 3 and, therefore, the edge formed by the bottom wall of the channel and the adjacent surface of the valve member near the projection 7 will act as a cutting edge to cut off the material that has already been expelled through theslot 8.

It will be readily understood that I do not propose to limit my invention to the exact details of construction shown in the drawings and described above since the parts may4 be changed in size and shape within wide limits without deviating from the spirit of my invention as included in the claims below. For instance, the valve member 5 may be in the shape of a segment of asphere rather than a sphere as shown. Likewise, in some cases the valve member 5 may be provided with an opening therethrough rather than the channel 6 cut inwardly from the surface thereof.

What I claim as new and desire to secure by Letters Patent, is

1. The combination with a tube container having a neck provided with a discharge opening therethrough, of a closure therefor comprising a cover engaging said neck and having an elongated opening therein, a valve member movably mounted between said cover and said neck and having a projection extending therefrom through said opening in said cover, said valve member having a channel therein and being formed and arranged to be movable by a movement of said projection into a position whereby said channel will vprovide a passage from said opening in said neck to the opening in said cover through which material contained in Asaid tube' may be expelled therefrom, said valve member also being movable into a position` to prevent the expulsion of said material and said elongated opening in said cover being positioned and arranged whereby whensaid projection is moved in said opening the side walls of said opening will`guide said projection to move said valve into one of said positions.

2. The combination with a tube container having a neck provided with a discharge opening therethrough, of a closure therefor comprising a cover engaging said neck and having a slot therein, a valve member seated` between said cover and said neck and havinvF a projection extending therefrom througli said slot in said cover, and said valve member having a channel therein and being formed and arranged so that when said projection is moved to one end of said slot said valve member is moved into a position whereby said channel will provide a passage from said opening in said neck to the slot in said cover through which material contained in said tube may be expelled therefrom, and said valve member also being formed and arranged so that when said projection is moved to the other end of said slot said valve will be moved into a position to prevent expulsion ontY said material. L

3. The-combination with a tube container having a neck provided with a discharge opening therethrough of a closure therefor comprising a cover threaded on said neck and having an elongated opening therein, a valve member movably mounted between said cover and said neck and having. a projection extending therefrom through said opening in said cover. said valve member having a channel therethrough and being formed and arrar ged to be movable by a movement of said projection into a position whereby said channel will provide a passage from said opening in said neck to\ the opening in said cover through which material contained in said tube may be expelled therefrom, and said valve member also being movable into a position to prevent the expulsion of said material, and said projection and said elongated opening being arranged so that said projection is movable only in a plane substantially parallel to the axis of said cover.

4. The combination with a tube container having a neck provided with a discharge opening therethrough and haying a substantially hemi-spherical depression extending inwardly from the upper end thereof, of a closure therefor comprising a substantially spherical valve member seated -in said depression, a cover having the inner surface thereof arranged to follow the contour of said valve member and otherwise adapted to maintain said valve member on its seat, said cover having a slot therein and said valve member having a projection extending through said slot, and said valve member having a channel therein and being formed and arranged so that when said projection is moved to the inner end of said slot said valve member is moved into a position whereby said'channel will provide a passage for the expulsion of material from said tube and said valve also being formed and arranged so that when said projection is moved to the outer end of said slot said valve member will prevent the Vexpulsion from said tube of saidmaterial.

5. The combination with a tube container having a neck provided with a discharge opening therethrough and having a substantially heini-spherical depression extending inwardly from the upper end thereof, of a closure therefor comprising a substantially spherical valve member seated in said depression, a cover having the inner surface. thereof arranged to follow the contour of said valve member and being threaded on said neck, said cover having a slot therein whose side walls extend in a plane substantially parallcl to the axis of said cover, said valve member having a projection extending therefrom through said slot, and said valve member also having a channel in the surface thereof extending between nearly diametrically oppo site points and arranged whereby when said projection is moved to the inner end of said slot said channel will extend from the opening in said neck to the slot in said coverto provide a passage through which materlal contained in said tube may be expelled therefrom and whereby when said projection is moved to the outer end of said slot expulsion of said material will be prevented.v

In witness whereof I have signedmy name to the foregoing specification.
