CLOSURE FOR TUBES OR THE'LIKE.

- Application filed August 5, 1926. Serial No 127,244.

This invention relates to a new and improved form of closure for containers of various kinds and while it is shown as ap plied to the ordinary collapsible tube such as used for dispensing pastes or liquids of all kinds, the invention is also applicable to other containers, cans, jars, or the like.

The object of the invention is toprovide a form of closure which will" do away with the ordinary screw cap which is easily lost.

a sanitary closure which will securely seal the contentsv of the tube-or container from air and prevent leakage. Advantages of the closure reside in its cheapness of manufacture and in the fact that itjs not bulky or cumbersome and cannot be easily bent or in- ,jured so as to become inoperative The device embodies a sliding cut-ofl' which positively and cleanly severs that portion of the contents which has been extruded or dispensed from the container, leaving a clean tube cover or cap. The device is so constructed that the pressure upon the sliding cut-ofl' may be adjusted so that it may be firmly locked in closed position or released to the desired degree to permitfmore or less easy operation of the slide. 1

With these and other advantages, the device may be made inexpensively and from stamped metal parts and-an ordinary com pressible gasket or washer. It is, therefore, a desirable adjunct to containers or tubes of all types. I p Several forms of the invention are illustrated in the accompanying drawings, but it will be appreciated that even more specifically difl'erent embodiments of the invention may be made within the scope thereof as set forth in the appended claims. In the drawings: Figure 1 is a view of the new form of closure applied to a collapsible tube;

Figure 2 is a section of the preferred form of closure;

Figure 3 is a plan thereof; Figure 4 is an end view of the slide or cut-ofl';

Figure 7 is a section through 'a second modified form of the invention; and Figure 8 is a plan thereof.

of the cap The container, in the form of a collapsible tube, is shown at 1, the upper end being fprmed with the usual screw-threaded nozz e 2. Vi

.Referring to the form of the invention shown in Figures .2 .to 4, the end of the tube is provided with a threaded cap 5 formed of sheet metal and the screw threads'adapted to fit over the nozzle. The'cap is formed with a circular, enlarged upper surface 6 about which is formed the. fiange 7-, this flange being extended aboutthe entire circumference of the cap except where it is cut away or removed, as at 7, for the passage of the slidelO which is of substantially the same hei ht as the flange 7.

11 top 'o'f'the nozzle is placed a ringshaped washer 11 which. may be of cork, rubher, or other compressible or yielding material as may be found practicable, the washer lying'below and in contact with the under face of the slide so that the pressure upon the slide may be varied by a) slight turning of the cap.

The slide or shutter 10 is formed at one end upon'a curve 15 equal tov the curvature and at that point is provided with a tip or ange 16 bent upwardl to provide a purchase or hold for withd r slide. At the sides of the part 16, the metal of the slide is bent downwardly to form two wings 17 which fit against the outer circumference of the cap when the slide is closed. It will be observed in this form of the invention that the slide is of such length that when it is ,withdrawn to its 'full extent, as illustrated in full lines in Figures 2 and 3 the opening in the nozzle 2 is com letely uncovered. The inner end of the slide may be cut away.,-as at 20, for this purpose. The

awmg. the I slide is retained within the cap by two wings where the slide is located. The cover or lid 23 has a cut at 23 therein, through which theslide 10 may extend. In order that the lcover 23 may be easily assembled with cap 5, so that cut 23 will register properly with cut 7, cooperating projections and indentations ma be formed in cover 23 and flange as indlcated at 7", so that these parts may be clicked into registr The center of the cover is provided wit a hole 24-. which re isters with the hole in the nozzle.

n the form of the invention shown in Figures and 6, the gasket 30 extends over the whole of the cap which necessitates" a somewhat higher flange 31 about the cap.

ln this form, a ring 32 is held in a turnedunder extension 33 of the slide and may be used for pulling the slide outwardly and i also for hanging up the tube or container.

In the form of the invention shown in Figures 7 and 8, the construction resemloles that shown in Figures 2 to 4:, except that the slide or cut-ofi is extended the full width of the cap andis formed with a narrhw aperture 35 which is adapted to register with an aperture 36in the cover or top, which latter may be of the same shape or difierent shape from the aperture 35. The lateral extensions to prevent the withdrawal of the slide are indicated at 38.

In all of the forms shown, the asket or I washer, which has a hole therein or extrusion of the contents of the container, is ada ted to he urged against the under side of t e slide and that in turn against the cover ortop. 'lheslide is of such area as substantially to cover the entire cross-sectional area of the container nozzle and also to provide contact of the slide with the reater part of the surface of the gasket. the contents of the container can, therefore he tightly sealed and the pressure exerted can be so great as to prevent the withdrawal of the slide. By loosening the cap slightly,

the slide may be withdrawn. The slide will always cleanly sever the contents oil the container from that which has been extruded, making a sanitary package andv one which will not permit deterioration of the contents by exposure to or admission of the air to the interior, The slide may be made .very thin so that. none of the contents of the tube will clog the opening and at the same time the opening may he wi ed clean. The. rovision of ,t a lateral extensions upon al forms of slides prevents the withdrawal thereof and does away with extenda not ing the slide to both sides of the cap, vthe.

slide riding without tilting upon the upper edge of the nozzle. The slide is, theretore, com letely housed within the cover and cane bent or distorted when not in use. ln prior forms in which the slide extended clear through the cap, the extended end of the slide could be easily bent or distorted and the device rendered inoperative forthat The lateral extensions and the reason. flanges upon the slide serve, by chntact with the flange 7, to align the slide properly when at either limit of its movement.

lin the" constructionshown in Figures 2to 6 inclusive, the fact that the slide terminates short of the aperture makes possible. to r use a shorter slide than in prior forms, in fact the slide in an of the forms is not longer than the widt ,of the cap.

lhe entire construction is very chea light, and compact. It may be readily ma e and easily assembled." It operates as a'positive cut-ofi' and as an air-tight seal or closure. It cannot get out of order and is squall suitable for paste, powder or liquids. lts ot er advantages will be apparent to those familiar with the art and with the" reuirements of this form of container.
