CAP CONNECTER FOR CONTAINERS Filed Sept. 17 1928 Patented Dec. 15, 1931 UNITED STATES" PATENT oFnca EDWARD K. MGNEAL, OF FOBESTVI'LLE, NEW YORK GA]? CONNECTER FOR CONTAINERS Application filed September 17, 1928. Serial No. 306,500. I
This invention relates to connecters or retaining devices for caps or closing members of containers, which serve to prevent the losing or misplacing of the caps when they are removed from the containers.
The improved retainer is particularly adapted for holding caps which are used for closing collapsible tubes, for the purpose of preventing the loss or misplacement of a cap kind which is of simple, practical and inex-' pensive construction and can be readlly se-- cured to the cap and container; also to provide a connecter of this sort which can bemade entirely of a single piece of sheet material; and also to provide a connecter of this kind which is so formed that a number of said connecters can be struck at one time from a sheet of material in a single stamping operation with a minimum waste of material.
Other objects are to construct a connecter of the character set forth which is formed of resilient sheet material and is provided with an apertured part which may be sprung over a projection on the detachable cap in a manner to hold the cap connected therewith while nevertheless permitting free rotation of the cap for detachment from and attachment to the tube or container; also to provide an improved attachment of the retainer or connecter to the container.
Other objects and advantages will be apparent-from the following description of an embodiment of the invention, the novel features of which will be set forth in the appended claims-and illustrated in the accompanying drawings in which Fig. 1 is a side elevation of the upper porsheet materi l tion of a collapsible tube or container with its cap or closure member and one of the improved connecters attached thereto.

The container illustrated comprises the so of a connecter of usual cylindrical body portion 10 closed inany suitable way at its lower ends, not shown, and having a conical or tapering upper end wall 11 terminating in a neck 12 which is provided with the usual discharge orifice 85,
13. The neck 12 may be exteriorly threaded as shown at 14, for the reception of an interiorly threaded screw cap 15 having a transverse top wall or portion 16. The container and cap, so-far as described do not constitute a part of the invention and are illustrated merely to show how my invention may be applied to a container and cap.
The lmproved connecter, see Fig. 6 is formed of a single piece of thin, resilient and includes a relatively narrow and straight ribbon-like body portion 17 having at one end an aperture 18 by which it is connected'to the cap 15, and at its opposite end an enlarged apertured portion 19 for connection to the neck of the container.
In accordance with the particular construction illustrated, the cap 15 is provided with a relatively small, transversely elongated knob 20 which is preferably disposed centrally on the cap and is connected to the top face of said cap by a reduced cylindrical apply the connecter over'the knob 20, the
aperture 18 is passed over one end of the knob with the slit 22 extending lengthwise over the knob, and then by depressing the connecter, the tabs 23 are deflected so that the slit portion 22 can be passed downwardly over the "knob 20. When the aperture 18 and its connecting slit portion 22 have passed below the knob 20, the resilient tabs or portions 22 of the material adjacent the slit will spring back into their original positions,,and thereby form an obstruction to the accidental disconnectionbftheconnecter from the cap, while nevertheless permitting free relative movements therebetween.
If desired the enlargement 20 of the pro jection 21 may be formed by the usual beading or flattening operation after the projection has been inserted through the aperture 18, in which case the slit 22 may be omitted.
The connecter may besecured to the con tainer in any suitable or desired manner,
preferably such a way that theconnecter is merely forced over the end or neck of the container and is held in place thereon and preferably also against turning. In the particular embodimentof this invention illustrated in Figs. 2, 5 and 7, that portion of the neck 12 of the container immediately adjacent the top wall 11 thereof and below'the threads'l i is specially formed for the reception of the connecter. For this purpose, the neck 12 (see Fig.5) is undercut at one side to form a recess or notch 25 having a transverse vertical bottom or inner wall 26 and diametrically opposite this recess 25 the neck is formed with an oblique, inwardly and upwardl directed shoulder or depressed flat face 2 the top edge of which terminates inwardly beneath one of the lower threads 14 of the neck, which forms therewith an under cut stop shoulder 27a.
vThe enlarged end portion 19 of the connecter in the particular form shown, is formed with an aperture 28 adapted to pass over and surround the neck of the container. This aperture, at the outer end of the enlargement, is provided with a transverse edge 29 and, opposite thereto, with an inwardly directed tongue or projection 30 terminating in a transverse edge 31. The aperture 28 and the tongue 30 are so proportioned that by inclining the connecter as shown in Fig. 7, with a portion of the neck of the container projecting obliquely therethrough, the edge 29 may be engaged in the recess 25 in the neck. If the body portion of the connecter 17 is now moved downwardly, the resilient tongue 30 will snap over the threads 14 and will come to rest lying substantially flat against the oblique recessed face 27, with its free edge 31 engaging beneath the stop shoulder 27a, or thread on said neck so that threads on the 'cap do i not engage the tongue 30.
In this way the connecter is attached to the neck of the container in a manner to prevent its free rotation thereon and is maintained in such relation thereto that it is prevented from interfering with the turning movement of the cap 15 when manipulated to apply it to or disconnect it from the container, as the spring tongue will act to draw the edge 29, into the recess 25 and hold it firmly against the face 26. The connecter described may, however, be attached to a container neck not having the special means described for holding the connecter against turning, as sho wn'for example, in Fig. 9. This figure illustratesthe upper portion of a container having a neck 12a of standard or unmodified form provided with the usual threads 14a. The connecter hereinbefore described can be applied to the container of Fig. 9 by passing its larger end down over the threads 14a, until it surrounds the neck portion 12a and the tongue 30a engages beneath one of the threads near the base of the neck.
When the cap is disconnected from the container the resiliency of the connecter will cause the cap to be moved away from the neck of the container as shown. in dotted lines, Fig. 1, so as to permit free access to the contents of the container. I h Preferably, to stiffen the tongue 30' and prevent its deformation, it is corrugated lengthwise, as shown at 32.
' The form of the connecter illustrated is such that anumber of them can be struck at one time by a single stamping operation from a sheet of material, as indicated in Fig. 8, the enlarged ends of alternate connecters being disposed at opposite edges of the sheet and the narrow body portions disposed side by side alongthe'intermediate portionsof said sheet. In this manner the connecters are produced with a minimum waste of material. Any other manner of stamping out the connecters may be provided, if desired.
By means of the construction described, it is possible for the seller of the container to merely supply an unattached connecter with each container, which connecter can then be readily attachedtothe container and cap by the user. If he desires, 'or if the seller prefers, the connecters can be attached either to the container or cap, or to both, before the containers are sold.
Since the connecters are attachedmerely by inserting'the neck of the container through one aperture of the connecter and by inserting the knob of the cap through the other aperture, no special machine or apparatus is necessary to attach the connectors, thusgreatly reducing the cost of applying the connecters to the containers and caps. The connecters can be produced at a very low cost by means of punching or stamping operations,
and the construction illustrated makes it possible to form the c'onnecters of a variety of different materials, such, for example, as metal, celluloid, rubber or other materials.
If the connecter is made of a resilient material, the connecter will normally tend to either partially or entirely straighten itself when the cap is released from the container,
. so that the cap will then be held away from the discharge opening in the neck of the container and will thus be out of the path of material discharged from the container.
A connecter 85 of slightly modified form is shown in Fig. 10. In the connecter 35 the loop 36 thereof is provided with a plurality of spaced, radially disposed tongues or projections 37 two being shown. This connecter can be easily pushed down over the neck, and as there is no undercut or specially formed portion on the latter, no precaution need be taken to place the parts ofthe connecter and container in a particular relation to the neck of the tube or container. The edges of the projecting portions may be made sharp as shown to engage the metal of the neck and prevent the connecter from turning relatively to the neck.
