' 4 Claims. (01. 221-60) My invention relates to an improved holderor retainer for the caps of containers, more particularly for the screw caps of collapsible tubes, andits principal object is to provide a simply constructed retainer which will not only prevent loss of the cap or its undesired separation from the tube, but will also hold the cap in a position to prevent interference with free use of the contents of the tube.

Various forms of cap retainers have been heretofore proposed and my invention is especially re lated to non-metallic flexible retainers, usually of rubber. Retainers of this kind heretofore employed had certain disadvantages among which may be mentioned the tendency to twist when in use, the lack of suflicient rigidity to hold the cap out of the path of discharge from the tube and the inefiiciency of the device if the openings for receiving the cap and tube, respectively, were either too large or too small.

Another object of my invention is to obviate these defects in flexible retainers and I accomplish this object by providing two forms of my invention in one of which the flexible retainer is wound about with suitable material and in the other of which I interpose between the retainer. which may be fiat, and the breast of the container a disc made of material which has relatively high adhesion to the retainer and relatively slight adhesion to the material of the container, usually metal.

The invention is illustrated in the accompanying drawing in which Fig. 1 is an elevational view of a collapsible container in open position;

the screw cap being connected to the container by one form of my improved holder; Fig. 2 is a plan-view of the holder; Fig. 3 is a similar view of a disc interposed between the retainer and the breast portion of the container; Fig. 4 is a similar view of a modified form of holder in which the disc is positioned in one of the holder openings; Fig. 5 is an elevational view of a portion of a container showing the manner in which the holder of Fig. 4 is applied; Fig. 6 is a plan view of a modified holder consisting of a rubber core wound around with a fibrous strand; Figs. 7 and 8 are elevational views of parts of containers illustrating the application of the holder of Fig. 6; Fig. 9 is a plan view of a slightly modified holder of the kind shown in Fig. 6 and Figs; 10 and 11 are elevational views of containers illustrating the application of the holder of Fig. 9.

Referring to Figs. 1 to 3 of the drawing, IO'

denotes a collapsible tube or the breast portion I I, the neck container having I 2 and the threaded mouth or nipple l3 designed to be closed by the screw cap It. The holder, shown in Fig. 2, consists of the intact intermediate web portion l5 and the oppositely disposed eyes or holes 16 and H. The hole H is designed to receive the re- 5 duced part ll of the cap l4 and the hole l6 to receive the neck 12 of the container Ill. The holder is made of flexible material, usually rubber, and hence has practically no rigidity; the consequence is that unless preventative measures 10 be provided the cap tends to get into the way of the contents issuing from the container and interfere with satisfactory operation. To obviate this difiiculty, I interpose between the breast portion H of the container and the adjacent part of 15 the holder a perforated disc 18 as shown in Fig.

} 3. The disc is made of a suitable material, such as smooth paper, celluloid or the like, having relatively great adhesion to the holder but relatively slight adhesion to the container metal. As a re- 20 suit of this construction, the cap when removed from the nipple l3 may be moved or thrown into the position indicated in Fig. l, where it will remain out of the path of the material issuing from the container, until the cap is positively replaced. The disc is slotted at I9 to facilitate its application to the neck l2.

In the modified construction of Figs. 4 and 5, the disc I8 is of double conical form and its intermediate portion is seated in the hole It of the holder IS. The disc is slotted at i9 The holder I5' is also provided with the hole Il to receive a screw cap and the application of this device to a container in is illustrated in Fig. 5. Fig. 6 shows a holder in the form of a loop consisting of a rubber core l5 wound about with a fibrous thread 20, such as silk, cotton, linen or the like, to impart a certain degree of rigidity to the holder. Intermediate its ends the holder is provided with a clip 2| thus providing the holes or openings [6 and I! to receive the neck and cap, respectively, of a container. In Fig. '7 the holder of Fig. 6 to a container Ill having a bulbous portion 22 above the breast part I I and a collar 23 above the portion 2|. The opening lfi engages the container between the collar 23 and bulbous portion 22, and the opening l'l part of the loop in which the opening l'l is formed being wholly or partly enclosed in a head 24 formed at the base of the cap M In Fig. 8 the eye Hi engages the neck of a sifter top can Hi below a collar 23 while the other eye 55 is applied engages the cap, that engages the screw cap M and is enclosed in a bead 24 formed at the base of the cap.

The holder shown in Fig. 9 is much like that shown in Fig. 6 except that the clip 2 l is nearer one end of the loop than the other thereby providing openings 3 and l 1 difiering in size from each other. In Fig. 10 the opening I6 contains the neck I2- of the container In and the opening ll is traversed by the reduced portion II of the cap M which has a knurled overhanging head I4 and a bottom flange N at opposite ends of the reduced portion I'I In Fig. 11 the holder is applied to a container W with the opening l6 encircling the container above a bulbous portion 22 and below a collar 23 and the opening l'l having therein an eye 25 on the can M My improved retainer is applicable to a great variety of container constructions and the forms shown in the drawing are but a few of the many with which it may be efiectively used.

I claim:-

1. As a new article of manufacture, a holder for connecting a cap to a container, said holder comprising a flexible loop consisting of a rubber core and a fibrous material wound thereabout and means dividing said loop into oppositely disposed eye portions.

2. As a new article of manuiacture, a holder for connecting a cap to a container, said holder comprising a rubber core, a fibrous material wound thereabout and a clip intermediate the ends of said holder and dividing the same into two oppositely disposed eye portions.

3. In combination, a container, a removable cap therefor, a holder for connecting said cap to said container, said holder comprising a flexible member having oppositely disposed openings therein to receive the cap and a part of the container, and a disc interposed between the material of said holder and said container, said disc consisting of a material having relatively great adhesion to said holder and relatively slight adhesion to said container.

4. In combination, a metal container, a removable cap therefor, a holder for connecting said cap to said container, said holder comprising a strip of rubber having oppositely disposed openings to receive the cap and container neck, respectively, a slotted disc interposed between said holder and the material of said container, said disc having relatively great adherence to the rubber of the holder and relatively slight adherence to the metal of the container.
