- the wall of the outlet nozzle is relatively thin, and in consequence very little-of the tube contents will adhere to the surfaces, and such as may gather will be readily scraped ofi by the valve; also. the auxiliary outlet nozzle acts as a continuation of the ordinary tube outlet, and assures a better discharge than coming from the short outlet of the tube.
- Figs. 1, 2 and 3 The embodiment of Figs. 1, 2 and 3 is attached toan ordinary collapsible tube 10 having an internally threaded outlet neck 12 by screwing it on the neck 12.
- a tube with a threaded neck of this description is shown in Fig. 4.
- I modify the embodiment of Figs. 1, 2 and 3, dispensing with the lug 26 and projection 27. and providing the nozzle 15 with the stop 29 adjacent the rim 18.

- the letter R indicates how the edge 18 would appear if struck from the pin 20 as a center. It is therefore obvious that the edge 18a of the opening of the nozzle 15a tends to bend the arm 21 away from the pin 20 somewhat so that the lid 23 will always fit tightly against the end of the nozzle 15a.

CLOSURE FOR COLLAiPSIBLE TUBES AND OTHER RECEPTACLES Application filed August 20, 1928. Serial No. 300,892.
This invention relates to closures for col lapsible tubes and other receptacles. It has for its particular object to provide a very simple mechanism to open and close the outlet end of a tube in such a manner that it can. be conveniently operated, always be handy and accessible, and at the same time maintain the outlet end of the tube clean and free from the contents of the tube; thus preventing portions of the material from lodging around the edges of the outlet as is the case with some closure devices.
Another object is to provide an outlet nozzle which has its orifice, remote from the end of the collapsible tube, and its rim so thin and fine that there is virtually no place for the material to accumulate.
A further object of the invention is to provide an auxiliary outlet member which may be readily attached to the outlet end of any collapsible tube now on the market.
An additional object is the provision of a special locking member on said outlet member, fitting only supplementary locking members on the tube, so that such a member may be used only with those tubes which have means adapted to cooperate therewith.
With this and other objects in view my invention consists ofan auxiliary outlet nozzle of elongated shape with its orifice remote from its attachment end, and a very thin edge around the orifice. made up as a unitary member separate from the collapsible tube having a closure member 5 thereon. This unitary member is adapted to be applied to the outlet end or head of a collapsible tube. The invention consists further in the provision in such an outlet nozzle of ,means engaging the screw-threaded por-,
tion of the outlet end of the collapsible tube,
to render it applicable to a standard tube outlet. The invention consists further in the combination of such a unitary outlet member with special locking means engaging with corresponding locking means on the tube.
My invention consists further in the features hereinafter described and shown in the accompanying drawings and finally printed on it in the claims.
In the accompanying drawings,

Fig. 13 is a side view showing an auxiliary nozzle with a base or bottom shaped to secure it in place; and
Fig. 14 shows one more modification, partly in section, and somewhat similar to the' device of Fig. 13. v
The same-numerals identify the same parts throughout.
Referring to the drawings and more particularly to Figs. 1, 2 and 3, the elongated auxiliary nozzle 15 has at one end an interiorly screw-threaded portion 16, which is adapted to engage the exterior screw-threads on the end 12 of a collapsible tube 10 of the usual type. At the other end, the nozzle 15 is provided with an orifice 17, and the rim portion or edge 18 is very thin and narrow so as to prevent the contents of the tube from collecting thereon. The edge 18 is very carried an arm 21, which has a handle 22,
and a closure or lid 23. This valve or lid seats on the rim 18 of the outlet nozzle 15 when-the valve is closed. As the valve is closed it slides over the highest point 25 of the edge of the nozzle and the arm 21 is resilient to permit the lid to yield as it passes'the point 25. and then fit tight on the edge 18.
The arm 21 has a lug 26, which engages a projection- 27 on the side of the nozzle. As the valve closes the lug 26 goes under the project-ion when thevalve-seats itself upon the rim 18. The projection 27 cooperates with the lug 26 and serves to press the valve against the seat. The valve 23 is slightly curved to match the curve of the end of the nozzle. After the valve passes over the edge of the end 25 of the nozzle it snaps into position. As illustrated at 28 the stem is twisted which aids in its flexibility. This form of closure member may be applied to a nozzle having screwthreads to engage the screw-threads on the end 12 of an ordinary collapsible tube, as shown in Fig. 4, or to any of the other forms of nozzle members shown.
It will be particularly noted that the wall of the outlet nozzle is relatively thin, and in consequence very little-of the tube contents will adhere to the surfaces, and such as may gather will be readily scraped ofi by the valve; also. the auxiliary outlet nozzle acts as a continuation of the ordinary tube outlet, and assures a better discharge than coming from the short outlet of the tube.
The embodiment of Figs. 1, 2 and 3 is attached toan ordinary collapsible tube 10 having an internally threaded outlet neck 12 by screwing it on the neck 12. Such a tube with a threaded neck of this description is shown in Fig. 4.
As is further indicated in Fig. 4, I modify the embodiment of Figs. 1, 2 and 3, dispensing with the lug 26 and projection 27. and providing the nozzle 15 with the stop 29 adjacent the rim 18. The arm 21 iscngaged by one end of a spring 30 which is mounted upon I the pin 20 and has its other end press against the adjacent side of the nozzle 15. By pressing down upon the handle 22 the closure 23 is withdrawn as indicated in broken lines in Fig. 4; and whenever the handle 22 is released the spring30 carries the arm 21 to move the closure back over the end of the nozzle 15 until it strikes the stop 29. This embodiment also screws upon the threaded neck 12 f an ordinary tube 10.
Inthe form shown in Fig. 5, the construction is the same as shown in Fig. 4, except that the stop 29 of the nozzle is omitted and the bend 31 in the arm 21 adjacent the lid or ca 23 acts as a stop by abuttting against the si e of the nozzle 15 adjacent the highest point 25 thereof. This construction also may be screwed upon a collapsible tube to attach it to the tube.
Fig. 6 illustrates a form which is of the same construction as Fig. 5 except that theat'tachin'g end 16 instead of being screwthreaded has a hole or slot 32 as shown in Fig. 7, and the outlet neck 12 of the c0llapsiscrew-threaded the same as in Fig. 1. The
In Fig. 10 the construction is somewhat similar to Fig. 5 except that the arm 21 has a tongue 33 to strike the side of the nozzle 15 adjacent its highest point and act as a stop for the closure 23. The under face of the closure 23 is shown as having a projection 23?) in the form of a wide bulge or protuberance to fit within the orifice 17 of the nozzle 15 and actually to close the outlet of this nozzle.
Figs. 11 and 12 show a nozzle 15 with attaching end 16 and having the outlet end 18 beveled in a diagonal direction. At the highest point of the nozzle is a bearing 34 which receives the pivot pin 35 extending in the direction of the length of the nozzle, and having a swinging closure 36. The closure has a projection 37 to provide a fingerhold; so that the closure can be swung from side to side to open or close the nozzle. The closure 36 has one end bent as shown at 36a, this end being engaged by the pivot 35, and the projection has a curved slot 38 in which is a stop 38a secured to the bearing 34. This stop pin 38a limits the movement of the closure 36.
The three form hown in F g O, 11
and 12 may have the end 16 internally screwthreaded to attach to a collapsible tube or they may be formed so as to be held by a bayonet joint the same as in Figs. 6 and 7.
Fig. 13 shows a form siniilartoliig; 1 except that, in' place of the internally: screwswaged edge 39 will prevent detachment of this nozzle. Of course instead of crimping the edge39 I may form this edge with a number'oui projections or fingers: to be bent under the 40, such. a collar being shown in Figs. 4,6 and 14.
In 14 the construction is similar to that of Fig. 13, except that the cone-shaped ;base 166 has number'of projections 41 which maybe resilient and are bent so that they first go around the collar 40 and then are out-turned at their ends so as to extend away from the side of the tube 10. These projections or fingers 41 are compressed against the outside of the tubelO by semicircular members 42 which form the laterally bent ends of rods 43. These rods may be part of a support or, stand for the tube and be moved towards and from each other like the.
jaws of a pocket-book. There will be two such rods 43 on each side of the tube and at their lower ends they will have suitable feet \Vhen the rods having the catch are fastened together the semi-circular portions 42 encircle the top of the tube gripping the fingers 41 to hold the nozzle in place and the tube is at the same time held fast within the stand formed by the parts 43. The cap in all forms except Figures 9 and 10 is curved slightly to fit the curved end of the nozzle 15.-
In all of the embodiments, the auxiliary out-let nozzle is of elongated shape toposition the orifice thereof remote from the outlet end of the collapsible tube itself, and proriding the end of the outlet nozzle with a very thin edge; so that the least amount of material may adhere to the surface. The closure valve in all cases is so arranged that such material is readily removed by the valve, whereby the rim is maintained in clean condition. This enables the tooth brush or the shaving brush to readily wipe oii an of the adhering material and there is not ing on the auxiliary outlet nozzle'to act to collect on gather any of the material.
I have shown various embodiments of my invention; but changes may be made therein without departi'n gfrom the spirit of my invention as define in the annexed claims.
