Application filed ,August 29, 1921. Serial No. 496,704.

To all whom it may concern:

Be it known that I, WILLIAM E. HOLDEN, a subject of Great Britain, residing at Crescent City, Del Norte County, and State of California, have invented a new and useful Improvement in a Container, of which the following is a specification.

My invention relates to containers for plastic substances .wherein a pliable envelope formed from a non-metallic material .is mounted within a casing and arranged to be twisted to expel the tcontents through a spout. p

The primary object of my invention is to provide an improved container for plastic substances such as tooth paste, cold cream and the like.

Another object of my invention is toprovide a container in which a plastic substance may be retained and from which it may be expelled without contact with metal.

A further object of my invention is to provide improved means for dispensing a plastic substance from a container.

' A still further-object is to provide an improved device of the character described that presents a pleasing appearance and which may be manufactured at a'low cost.

A still further object is to provide a container which may be packed for shipping, or carried among the personal effects of a user without danger of breakage with the resultant loss of contents and damage to surrounding objects. I

I accomplish these and other objects by means of the device disclosed in the drawings forming a part of the present specification wherein like characters of reference are used to designate similar parts throughout said specification'and drawings and inwhich,

Fig. 1 is a vertical section of my improved container disclosing one manner by which to compensate for the shortening of the envelope. r

Fig. 2 is a broken side elevation of Fig. 1

showing the envelope partially twisted to expel a portion of the contents.

Fig. 3 is a broken side elevation showing another manner of compensating for the shortening of the envelope.

Fig. 4 is a side elevation partially broken away and shown in vertical section to disclose a modified form of casing arranged to permit shortening 01' the envelope.

Figs. 5, 6, and 7 are roken vertical sec tions showing further methods by which'it is possible to compensate for the-shortening of the envelope when twisted.

Referring to the drawings the numeral 1 is used to designate in general a casing provided with arotatable cap 2'having a spout 3 formed thereon, and a bottom plate 4. An

envelope 6 is secured between the cap 2 and the plate 4 and arranged to receive a quantity of a plastic substance 7 in such a'man- .ner that when either the cap or casing is r0- tated with respect to the other, the envelope will be twisted to expel the contentstherefrom through the spout 3.

The casing 1 may be made of any desired shape or ornamental design, but for convenience in illustration I have shown it as a cylindrical member having annular flanges 8 outwardly turned upon the ends. The bottom plate 4 is held against the lower flange 8 by crimping a base piece 9 to enclose thefiange and the edge of the-plate. The cap 2 is shaped upon the edge thereof to form a pair of annular channels 11 and 12, the

lower channel 12- being turned over the upper flange 8 to form a rotatable connection therewith.

The cap 2is provided with a lining 13 shaped to fit the inner side of the cap, the

. outer edge of the lining 13 being introduced into the channel 11 and the inner edge being brought outwardly through the spout and secured by a threaded collar 14 crimped upon the outer side of the spout 3. A closing cap 16 is threaded to screw onto the collar 14 to normally close the spout.

The edge of the envelope/6 at the large end o f the cone is introduced into the channel 11 together with the lining 13 and the adjacent portions of the cap crimped together to firmly secure both the lining and the top of the envelope. In this manner the casing and cap is completely lined in such a. manner that any substance introduced into the containing envelope 6 will be completely protected from contact with metal or other materialfrom which the casing members are made.

The small end of the envelope 6 is secured to the bottom in any convenient manner, as by passing the extreme tip of the envelope through an aperture 17 and firmly clamped against the plate 4 by means of a disc 18, as shown in Fig. 1, orby securin the tip directly upon the top of the p ate in any suitable manner.

B securing the envelope between the rotata le cap 2 and the bottom plate 6, a rotation of the cap with respect to the casing will operate to twist the envelope, and as the stress will be imparted to the apex of the cone where the resistance is the least, the

contents of the envelope will be" forced up-1 wardly-and out through the-spout 3 when the closing cap 16 is removed. As is readily seen, the continued relative rotation of the cap and the casing in the same direction will tighten portion at the lower end of the envelo e and at each rotation a greater portion 0? the lower end of the envelope will beclosed up and the contents eventually all forced upwardl and out of the envelope.

By twlstin t e envelope 6 in the manner above descri ed, the envelope would normallybecome so shortened as to revent total closure. To provide, the ad itional length of material necessary to compensate for the shortening of the envelope it is essential that means be provided for lengtheningthe envelope in proportion to the amount of material taken u by the twist. In the drawings I have i1 ustrated several methods which this may be accomplished. In

' l ig. 1, l have shown the, envelope 6 as formed with a plurality of pleats 19 which are normally held in folded position by starch or other stifiening material. As the envelope is twisted the pleats are drawn into extended position as shown in Fig. 2 of the drawings inthis manner providing an additional amount of material suflicient to ermit the envelope to be twisted to the top ereby entirely expelling the contents.

In Fig. 3 I have illustrated the envelope 6 as provided with a plurality of folds 21 normally held between adjacent coils of a spring22, the pressure of the spring operating to hold the excess material in reserve until the twisting stress becomes sufiicient to free the folds successively from the sprin In form of the device in which the casing 1 is formed from telescoping members 1 and 1". A rotation of either member relative to the other will operate to twist the envelope 6 and the inner. member 1 is free to advance into the outer member 1 to compensate for the shortening of the envelope due to the twisting, as shown in dotted lines. v

Fig. 5 illustrates another manner of providing additional material for the envelope, in this form, the tip of the envelope being drawn through a small aperture 23 in a resilient disc 24 of rubber or other suitable material secured upon the bottom plate 6 to a cover a larger aperture 26 therein. The exig. 4 I have illustrated a modified l ma permit longitudinal extension suflicient to compensate for the total shortening of the envelope.

Fig. 7 discloses a still further method of compensating for length, by slidably mounting the bottom plate 4 within the lower -l ortion of the casing 1, the edges of the p ate 4 being notched to engage ribs 29 formed upon the inner side of thecasing. The disc is made to fit tightly in the casing so as to be drawn u wardly only in accordance with the shortening of the envelope as shown in dotted lines. The ribs 29 prevent rotative movement of the plate 4 thereby causing the envelope to be twisted as hereabove described.

From the above description it is readily seen that my improved container is subject to wide variation in structure without departing from the spiritof my invention. The materials of construction may be varied to suit the requirements of any specific prod-. not, and the desi tiveness to the original product and to serve for ornamental purposes or as a toy after the contents have been removed.

My improved container is particularly designed to prevent contact with metal or other materials by which the contents of the container may in' any manner becomecontaminated or rendered unsanitary. In .collapsible metal tubes of the character commonly employed as containers for plastic substances of the character above mentioned, there is always the likelihood of certain chemical reactions between the metal of the container and the chemical composition stored therein, such reactions often con made to afford distinctaminating the contents by the formation of reactionv products of a detrimental character. My improved device, being entirely lined with a material which may be selected to meet the requirements of any particular product, edectually .prevents such contamination. The device may be manufactured at a low cost and the container will retain its original pleasing appearance even after the contents have been e xpelled.

' Having thus described my invention what.

I claim as new and desire to secure by Letters Patent is:
