3 Claims.

This invention relates to nozzles and particularly to a nozzle adapted for a container having compressible walls or portions for ejecting powder, graphite, or dry material.

This invention has for its object to provide a nozzle of the character specified so constructed that the nozzle will be effectively sealed before use and the portion of the nozzle acting as the seal can be broken off and used as a cap or closure.

Further objects of the invention will appear from the following description taken in connection with the drawing which forms a part of this application, and in which Fig. 1 is a plan view of a container and nozzle embodying the invention, this view being partly broken away and partly in section;

Fig. 2 is a side elevation of the structure shown in Fig. 1, the lower portion of the container being broken away and shown in section;

Fig. 3 is an enlarged sectional elevation taken substantially on line 33 of Fig. 1, looking in the direction of the arrows;

Fig. 4 is an enlarged elevational view of the upper end of the container and nozzle, the upper end portion of the nozzle being shown in section after the end portion has been broken off; and

Fig. 5 is a view similar to Fig. 4 showing the cap portion used as a closure for the outer end of the nozzle.

Any desired form or shape of container may be used in connection with the nozzle but in the form of the invention shown the container comprises sides or covers l and l l preferably formed of cardboard and being compressible inwardly to eject the material within the container. A collar or band I2 is disposed within the container inside the flanges I3 and I4 of the covers or sides l0 and II and a second collar or band I is disposed outside of the flanges.

The nozzle comprises a reduced inner portion 20, a central portion 2|, and an outer end portion 22. The portions 20 and 2| have a central bore or opening 23 therethrough. The outer portion 22, as shown at 25, seals the outer end of the opening or bore 23, and the portion 22 has an inwardly extending tapered opening 26 in the outer end thereof.

The nozzle may be formed of any suitable frangible material, and is assembled on the container in the manner shown in Fig. 3 with the inner end portion 20 extending through openings in the collars or bands I2 and I 5 and between the flanges l3 and M. The inner end of the por-- tion 20 of the nozzle is slightly enlarged to form a bead 21 which assists in retaining the nozzle in place. A flange 28 rests on the collar l5 or, as shown in Fig. 3, engagesan annular strip or band 29.

When the nozzle is assembled in the manner shown in Figs. 1 to 3 inclusive, the outer end of the bore or opening 23 is effectively sealed. However, when the device is to be used, the outer end portion 22 is broken off or cut off along the hue X--X shown in Fig. 3. The nozzle is then open at its outer end and after the device has been used the portion 22 which has been severed from the portion 2| of the nozzle can be inverted and the outer tapered wall 30 of the portion 22 is inserted in the recess 26, whereby the nozzle will be closed.

Although one specific embodiment of the invention has been particularly shown and described, it will be understood that the invention is capable of modification and that changes in the construction and in the arrangement of the various cooperating parts may be made without departing from the spirit or scope of the invention, as expressed in the following claims.

What I claim is:

1. A nozzle formed of frangible material having a bore extending to a point adjacent the outer end thereof, said nozzle tapering towards its outer end and terminating in a frangible portion reduced in cross section with said bore cs tending slightly beyond said frangible portion, said nozzle having an enlarged cup-shaped extension outwardly of said frangible portion, the

inner dimensions of said cup-shaped extension being such as to be frictionally received on said nozzle after the cup-shaped extension has bee-n severed on said frangible portion inwardly of the outer end of said bore to provide a closure for the bore in said nozzle.

2. A combined nozzle having an outwardly tapering portion and a closure member for containers, said closure member being initially integral with said nozzle and having alined, oppositely extending openings therein separated by a portion of solid material, the opening at the inner end of said member forming the outer end of the nozzle bore, the opening at the outer end of said member being dimensioned to fit over the outer end of the nozzle with the solid portion in said member forming a closure for the outer end of the nozzle when said member is severed at a point inwardly of the solid portion therein.

3. A combined nozzle and initially integral closure member adapted to be transformed into an open nozzle portion and a separate closure portion, comprising a member formed of frangible material, the nozzle portion of said memher being outwardly tapered and having' a. bore extending thereinto from one end, initially closed by solid material of the closure portion at the other end, and the closure portion of said memher being disposed at the outer end of the nem- 2 .i y 2,392,195 'Y 1 her and having a cavity dimensioned to receive the outer end of the nozzle after the closure portion of said member as been severed from the nozzle portionat a point inwardly of said solid portion to open the outer end of the nozzle bore.
