A further object is to provide novel forms of holders for the container whereby it can be used as a refill for the hollow handles of shaving brushes, for cream dispensers and for toothpaste holders or the like.

A still further object is to construct the container in a new and novel manner whereby prog tection can be efiected at low cost and the efficiency of the container as a collapsible structure is increased.

Another object is to provide simple and efficient means for collapsing the container for the g5 purpose of ejecting its contents in desired quantities.

A still further object is to provide a container the bottom of which is assembled therewith in a simple but durable manner whereby the seam formed at the juncture of the parts will resist normal strains to which the container is subiected while it is being filled or collapsed.

A still further object is to provide a container which, initially, is in a collapsed condition but which is expanded by the forceful injection of bulk material thereinto through the orifice provided at the outlet.

with the-foregoing and other objects in view which will appear as the description proceeds, the invention resides in. the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it-being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings the'preferred forms-of the invention have been shown.

In said drawings:

Figures 10, 11 and 12 show further modifications.

Figure 13 shows in collapsed condition the modified form of container illustrated in Figure 8.

Figure 14 is a section through the bottom portion of another modified construction of the container.

Figures 15, 16 and 17 are sections through another form of the device.

Referring to the figures by characters of refer ence, l designates a container formed oi a tube of thin ductil metal, the bottom portion of which is produced by folding one edge of the tube inwardly, as at 2, to lap an annular flange 3 formed on a disk-like member 4. After these parts have been assembled, as described, the space beneath the member 4 and that surrounded by the portions 2 and 3 is partly or entirely filled with a material 5 formed of metal fabric, plastic, or any other suitable material.

The tubular portion of the container is formed with a continuous thread formed therein by rolling or in any other manner found desirable, this thread being indicated at 6. By extending the threads spirally along the container the tube can be corrugated more readily than would other wise be possible and at the same time it is rendered collapsible in the direction of its length somewhat after the'manner of an accordion. 50

The top of the container is formed with a screw,- threaded neck 1 which normally is engaged by a cap 8 for sealing the contents of the container.

While it has been found practical to form the container as shown in Figures 1 and 2 as has.

- already been described, it is to be understood that if preferred the bottom of the container can be in the form of an inverted cup 9, as shown in Figures 8 and 13, the free edge portion of this cup being gripped within the bottom fold In of the corrugated tube I I and said parts being bound together tightly by an inverted disk I2.

A further modification has been shown in Figure 14 .wherein the edge portion of the container I3 is not folded but, instead, is clamped upon an inverted bottom disk I4 by a band or ring I 5.

All of the containers herein described are formed with the spiral or thread-like corrugations and all of them are initially produced in a collapsed form, as shown, for example, in Figure 13 wherein the corrugations are substantially fiattened on one another and the cup-like portion 9 of the bottom extends close to the neck 1. After a container has been formed in this shape the matter to be held thereby is forcibly injected into the container through the opening in the neck and will act to press against the bottom of the container I, acting somewhat like a piston, stretch the tube and open out the convolutions substantially'as shown in Figures 2 and 8. Caps can then be applied and the containers can be sold to customers for use in dispensing the contents with or without separate holders provided therefor.

While the contents of one of these containers can be ejected by removing cap 8 and pressing the bottomof the container toward the neck, thereby collapsing the container longitudinally, a special advantage is found in the fact that this type of container is especially adapted for use in connection with different kinds of holders. For example, such a container can be used as a refill for a holder in the form of a shaving brush handle, one form of which has been illustrated in Figure 1.

Referring to the Figure 1, I6 constitutes a tubular body portion closed at one end, as shown at I1, while its other end is open and is reduced annularly to provide a neck I8 the base of which is surrounded by a shoulder I9. On this neck are angular lugs 26 oppositely disposed and preferably formed with parallel inclined ends, as shown at 2|. Formed on the bottom I1 within the handle is a boss 22 having lugs 23 on the periphery thereof which are regularly spaced.

Removably seated in the body portion I6 is a sleeve 24 in which is rolled or otherwise produced, a screw thread 25. Each end of this sleeve is formed with regularly spaced notches 2B and when the sleeve is seated in the body portion I6 it fits snugly against the inner surface thereof.

A cap 21 is adapted to receive the neck I8 and has an interior annular groove 28 to which lead outlet slots 29 preferably inclined to correspond with the pitch of the ends of lugs 20. Thus cap 21 can be placed over the neck l8 until the lugs 20 reach the slots 29 at which time, by rotating the cap, the lugs will be caused to enter the slots 29, thereby drawing the cap 21 toward shoulder I9. Lugs 26 will ultimately enter groove 28 so that it thus becomes possible to rotate the cap relative to the body I6 without detaching it.

A cap 21 is formed with a central nozzle 30 surrounded by the bristles 3 I of a brush, these bristles being heldto the cap by any suitable means. The bore 3I in the nozzle is counterbored at 32 so as to receive the threaded neck I of container I.

Regularly spaced lugs 33 are provided in the cap where they will engage in the notches 26 in one end of the sleeve 24 so that the cap and sleeve can thus rotate together, it being understood that the bottom end of the sleeve containing notches 26 will be free to move past the lugs 23. Embracing lugs 23 is a notched end 34 of a guide sleeve 35 which is extended around boss 22 and within sleeve 24. Both ends of this sleeve are notched so that the sleeve can be reversed when desired. Obviously the lugs 23 will hold guide sleeve 35 anchored to the body portion I6 while at the same time lugs 33 will engage the threaded sleeve 25 so that it can rotate with cap 21.

Sleeve 35 has a desired number of longitudinal slots 36 and extending slidably within these slots are portions of a head 31 which is slidable in guide sleeve 35 and constitutes a seat for the bottom of the container I. These projecting portions of the head or follower 31 are joined to a screw-threaded ring which extends around and is slidable on guide sleeve 35 but is in screw-threaded engagement with the inner surface of the threaded sleeve 24.

Normally the head or follower 31 is located at one end of the slots 36 and ring 38 is similarly located. A refill tube or container I is inserted into the sleeve 35 so as to rest on the head or follower 31. This refill tube is first joined to cap 21 by screwing its neck into the counterbore 32. Cap 21 is placed upon and joined to the neck I8 as heretofore explained and lugs 33 will become seated in notches 34 at the upper end of sleeve 35.

When it is desired to dispense a portion of the contents of the refill tube or container I, the cap 21 is rotated relative to the body portion I6. As the threaded sleeve 24 rotates with the cap and as the sleeve 35 and threaded ring 38 are held against rotation by the body portion I6, it will be obvious that this relative rotation of the cap and body portion will cause the ring 38 and the follower 31 to feed longitudinally of the holder, the follower pressing against the bottom of the refill tube or container and collapsing said tube slightly so as to expel a portion of its contents from nozzle 30 into the spaces between the brush bristles.

After all of the contents of the refill tube or container have been expelled the cap is detached from the body portion, the empty tube which is guide sleeve 35 and the threaded sleeve 24 are bodily removed, inverted and reinserted into the body I6, thus bringing the follower 31, which had previously been elevated, into its lowermost position within the body portion. A new refill tube or container is then attached to the cap and is lowered into the sleeve 35 while cap 21 is applied. The structure is then ready for further use.

Another form of brush has been illustrated in Figure 8. In that structure a longitudinally slotted guide sleeve 39 connects a cap 40 with a base 4|, there being threaded rings 42 secured to the ends of ,the sleeve and screwed into the cap and base. The brush 43 is connected to a plug 44 which is screwed into the cap 46 and is adapted to be engaged detachably by the neck I of the container. This container is suspended within guide sleeve 39 and rests on a follower 45 which slides in the slots in guide sleeve 39 and is joined to a screw-threaded ring 46 surrounding the guide sleeve.

The body portion 41 of this device has a screwthreaded lining or sleeve 48 which is engaged by the ring 46. Thus by rotating the body portion 41 ring 46 will be shifted longitudinally to collapse the container as heretofore explained.

If cold cream or the like is to be dispensed and it should bedesired to deliver the matter into a In Figure 12 there has been shown a holder in bowl-like container, a structure such as illustrated in Figure 9 could be used. Instead of providing the cap 49 with a brush it is formed with a recessed end 50 into which the matter delivered from the container will be discharged. This receiver formed by recess 50 can be covered or protected by a detachable lid 5|.

Simplified dispensing means trated in Figures 10, 11 and 12. In Figure 11, for example, the collapsible container is inserted into a longitudinally slotted guide sleeve 52 closed at one end while its other end has a detachable cap 53 carrying a nozzle 5|. The neck of the container is with this cap so as to deliver material to the nozzle and a cover 55 is pivotally attached to the cap, as shown at 56 so as to house the nozzle. A spring 5'! bears against angular faces 58 on the have been illuscover near its pivot and serves to hold said cover in either closed or open position. By means of a finger piece 59' extending from the cover it can be swung to either of said positions by the thumb or a finger of the hand grasping sleeve 52. Follower 59 is slidable in this sleeve and is connected to an arcuate ring 60 which is slidable on the sleeve 52.

Instead of using a sliding ring the follower 6| can be actuated by a plunger 62 slidable in a longitudinally slotted sleeve 63. as shown in Fig. 10.

This plunger is joined to a spring restrained dog 54 the free end of which is adaytd to engage the inner surface of sleeve 63. By pressing inwardly on the plunger the dog will shift into or frictionally engage the wall of sleeve 63 and advance follower 6| so that it will press against the housed container l which is supported by the cap 65 detachably mounted on sleeve 63. Intermittent thrusts against plunger 62 will feed the follower intermittently against the container to collapse it and the pull exerted by spring 66 on dog 64 will be suflicient to maintain the follower in any position to which it may be moved.

detachably engaged the form of a sleeve 61 formed of a spirally wound band spring one end of which is attached to a cap 68 while the other end is detachably joined to a head 69. A container supported by cap 68 can be collapsed in the direction of its length by contacting the sleeve'6'l longitudinally.

Obviously, various other modifications can be made within thev scope of the present invention.

For example, and as shown in Figures 15, 16 and 17, an ordinary collapsible tube T can be compressed by a grooved spherical roller 10 advanced intermittently by a pawl and ratchet mechanism 1| operated by a spring restrained plunger I2 slidable along a slot 13 in the casing 14 in which the tube is retained by a cap 15.

What is claimed is: V

1. A container comprising, in combination, a spirally corrugated tube made of a plastic material provided at one end with an outlet nozzle, a hollow cup-shaped end piece extending inwardly in said tube to a distance substantially equal to the length of said tube when all the corrugations thereof have been flattened against one another, with the edge of .said tube being folded about the edge of said end-piece, and a disc fitting in said end piece so as to tightly hold the edge of said tube between the periphery of said disc and the edge of said end piece.
