CLOSUBE Application med November 1, 1926. Serial No. 145,544.

This invention relates broadly to a novel closure means for containers.

One of the objects of this invention is the production of a' closure or cap of novel con- 5 struction for containers-jwhich is relatively simple in construction'fand in operation. A still further object of this invention 1s f the provision of closures vfor containers which are adapted to preventl the material in the container from hardening so that the vpassages arel stopped up duringl the period when the structure is closed.

These and man other objects as will appearfrom the fol owing description .are obtained by means of this ,invent1on. This invention resides substantially in the combination, construction, location and relative arrangementof parts, as will appear from the following' disclosure.

Referring to the drawings in whlch the same reference numerals will be used throughout the several views to indicate the same or similar parts,

Fig. 1 is a side elevational view of a container employing closure means;

\ Fig. 2 is a cross-sectional view taken on the line 2-2 of Fig. 1, looking in the direc-- tion of the arrows.

Fig. 3 represents a vertical cross-sectional view in a modified form of closure device.v

*Y Fig. 4 represents a cross-sectional view of the same formshowing the cap partially removed, and

Fig. 5 is a crosslsectional yiewof the cap structure taken on' the line 5--5 of Fig. 2 looking in the direction of the arrows. Y My novel .construction is particularly .adapted for use ori-.containers for 'holding paste and other semi-Huid materials, such as 40 shaving soap, tooth paste, skin lotions,

creams, glue, etc. By means of this construction it is possible to revent the harden-` ing, of the material in t e passages of the closure means duringthe inoperative period of the`container.

In the drawings the container is shown at 1 with a suitable cap member secured thereto in any suitable manner having a' threaded integral 'extensionf3 which is hollow and which is provided-with aseries of openings 54 through the walls thereof. An extension 4, which ma be of any suitable cross-section; preferably circular, projects' froin the end of the hollow portion 3. The 56 extension 4 has a projecting wing or spline `,threadsof they member 7, and has a 4 extending throughout a portion of its l length above its surface a suflicient distance so as vto provide a sliding contact with the surface lof the bore extending throughl the cap 6. vBy this construction, when the cap 6 is rotated, the spline or wing 4 tends to scrape the surface of the bore clean, so as" .to remove inganni-themas@ material which may havebe'c rdenedgyvithin--the plassage. This prov'i l'convenient construc- 65. tion 'ffor pre-venting any stoppage of this passage. An internally threaded cap 6, having a central passage therein, is adapted to engage the threads on the hollow portion 3, and when it is closed, theprojection 4 extends into the openin in the cap to seal itl off. The portion o the walls through which the holes pass is conical and a similar conical surface on the inside of the cap engages with it to'secure the holes. The cap when rotated permits theejection ofthe contents of the tube without being removed. A slightly modified arrangement is shown in Figs. 3 and 4, where the containerl, as is usually sold, has thehollow threaded projection 3, on which` the usual cap is secured. By means of this modification, this cap is removed and discar'de and a hollow internally and externally t readed member 7 is screwed thereon. This member has a series of holes 8 through the wall thereof and has the integral extension 9. internally threaded cap 10 screws on to the external assage extending therethrough into -whichpthe projection 9 protrudes when the cap is seated. This-same construction is shown in Fig. where the cap has been loosened, so

that the material in the container may be forced out through the hollow member 7 and its h oles into the passage in thecap 10, and out through the -opening at vthe topv thereof. In constructions shown in Figs. 3 and 4 the contents of the tube cannot reach the threads because of the cylindrical coi1 100 v means forming part of said extension, of a seat and said cleaning means bein arranged of a closnre for said container having a plution, as it is defined in. the appended claims: rality of openings in a seat formed thereon 15 'What I seek to secure by United 'States and a cylindrical projection on said closure, Letters Patent is: 'Y of a hollow cap having val1 opening at one 1. The combination with a tube containeri end smaller than the passage thereln to re. for pastes having a threaded-projection with ceive said projection and means on said proa conical seat and holesin said seat, an exf jection'for cleaningthe interior of said cap tension on' said projection Aand cleaning dur'in the closing operation, said projection c osin the hole on said cap whenit lis moved tocosed position.

bIn testimony whereof I have hereunto set my hand on this 25'day of October,l A. D. '25

hollow cap for engaging said projection and extension, said cap seating on said conical to wipe the interior of said cap c can.
