COLLAPSIBLE TUBE Filed July 9, 1951 7 gwve'ntoc Eli Socolo/f q, Jack JHZzu/Man' Patented Jan. 2, 1934 UNITED STATES PATENT OFFICE This invention relates to collapsible tubes, and has for its object to provide, in a manner as hereinafter set forth, a tube of such class having as a permanent element thereof means whereby the expelling of the contents of the tube is had by a rolling action of the tube body in lieu of a folding action.

'A further object of the invention is to provide, in a manner as hereinafter set forth, a collapsible tube so constructed and arranged to overcome the necessity of clamping to the open bot- I tom thereof a closure therefor. I

A further object of the invention isto provide, in a manner as hereinafter set forth, a collapsi- 16 ble tube having a rolled end portion to provide for the closing of the bottom of the tube and further including as a permanent part thereof a roll coupled to and upon which such end portion is coiled or rolled.

20 A further object of the invention is to provide,

in a manner as hereinafter set forth, a collapsible tube so constructed and arranged and having as a permanent part thereof means whereby the expelling of the contents of the tube is had by a rolling. or coiling action and further whereby the rolled or coiled part of the tube is prevented from unwinding or uncoiling.

A further object of the invention is to provide, in a manner as hereinafter set forth, a collapsible tube whereby the contents thereof are expelled by a rolling up action of the tube and with the coils formed by such rolling up action automatically prevented .from unwinding.

A further object of the invention is to provide,

85 in a manner as hereinafter set forth, a collapsible tube having as a permanent part thereof a cylindrical roll carrying a rolled up or coiled portion of the tube body for the purpose of closing the end or bottom of the latter.

40 Further objects of the invention are to provide, in a manner as hereinafter set forth, a collapsible tube for the purpose referred to which is comparatively simple in its construction and arrangement, strong, durable, compact, thoroughly eflicient in its use, conveniently operated for the purpose of expelling the contents of the tube, readily assembled, and comparatively inexpensive to manufacture;

With the foregoing and other objects in view,

combination and arrangement of parts as hereinafter more specifically described, and illustrated in the accompanying drawing, wherein is shown an embodiment of theinvention, but it is to be understood that changes, variations and the invention consists of the novel construction,

modifications can be resorted to which fall within the scope of the claims hereunto appended.

In the drawing wherein like reference characters denote corresponding parts throughout the several views:-

Figure 1 is a perspective view of a collapsible tube in accordance with this invention.

Figure 2 is an elevation, partly in section of a collapsible tube in accordance with this invention.

Figure 3 is a perspective view of the cylindrical roll carrying the retaining member for the coils of the rolled up portion of the tube body.

Figure 4 is a view similar to Figure 3 with the retaining member omitted.

Figure 5 is a View similar to Figure 3 of a modified form of roll carrying a retaining member for the coils of the rolled up portion of the tube body.

Figure 6 is a view similar to Figure 5 illustrating the modified form of roll with the retaining member omitted.

Figure 7 is a fragmentary view in elevation of the tube body.

The tube may be formed from paper, fabric, metal or a combination of the latter and includes a container part 1, a breast part 2, a neck part 3, a tapered end portion 4, and the latter is coiled, as at 5 upon a cylindrical roll 6 whereby the said tapered end portion 4 is closed. Mounted upon the neck part 3 is a re- 35 movable closure cap 7. The length of roll 6 corresponds to the diameter of the container part 1. The diameter of roll 6 may be as desired. The roll 6 is formed with a lengthwise extending slot 9 for receiving the free end of the tapered 99 end part or portion 4. Secured to one end of the roll 6 is a retaining member 10 for the coils of the rolled part or portion 5 and said member includes a pair of arms 11, 12. The retaining member 10 is resilient. The arm 12 is of greater length than the arm 11, substantially of -bow shaped form and has its free end provided with a globular head 13. The arm 11 opposes that end of the roll 6 to which the member 10 is attached and the arm 12 is disposed lengthwise 100 of roll 6 and head 13 normally seats upon roll 6, but when the part 4 is rolled upon roll 6 the head 13 bears against the outer coil of such rolled part or portion 5 of the tube. The member 10 automatically functions to prevent the coils of the portion 5 from unwinding and further automatically acts to maintain such coils in position. The coiled part or portion 5 of the tube closes or seals the lower portion of the latter.

The form of roll shown in Figures 5 and 6 is the same as that shown in Figures 1, 2, 3 and 4, with this exception that in lieu of providing the roll, which is indicated at 14 in Figures 5 and 6 with a slot, it is formed with a lengthwise extending notch corresponding in length to the length of the roll and indicated at 15 and the latter receives the free end of part 4.

The slot 9, as well as the notch 15 provides means for connecting the tapered portion 4 of the tube to the rolls 6, 14 respectively. The form of fastening member employed in connection with the form shown in Figures 5 and 6 and which is indicated at 16 corresponds in construction to the form of fastening member 10.

When it is desired to expel the contents of the tube "the-container part 1 is wound or coiled about the coiled lower portion of the tube. Prior to the rolling up of the container part 1 from the rolled up or coiled portion of the tube the cap '7 is removed.

.Whatwe claim is:--

1. A collapsible tube having as a permanent part thereof a roll attached to and upon which the bottom portion of the tube is coiled, and means carried by the roll for permanently maintaining the bottom portion of the tube rolled during the rolling of the latter and when in rolled position.

2. In a collapsible tube, a coiling and coil retaining device therefor comprising, a roll having means for attaching the bottom of the tube thereto and upon which the lower portion of the tube is rolled up in a coil like manner, and resilient means anchored to, extended from and disposed lengthwise in spaced relation with respect to the periphery of the roll to prevent the unwinding of the coils during the formation of and when the latter are formed.

3. A collapsible tube comprising a container part, a bottom portion, a roll attached to said bottom 'portion and upon which the latter is coiled and further providing for the rolling up of the container part in a coil like manner to provide for the expelling of the contents of the tube, and means carried by the roll and engaging successively each outer coil for automatically maintaining the coils formed by the rolling up of the tube from unwinding.

4. In combination, a collapsible tube having a container part and a coiled tapered bottom portion for closing the bottom of the container part, said tapered bottom portion gradually decreasing in width towards its free end, a roll attached to said tapered bottom portion and upon which the latter is coiled, and means carried by the roll for maintaining said bottom portion coiled.
