UNITED STATES JOHN D. RAYMOND, OF DETROIT, MICHIGAN.

SCREW-CAP RETAIN ER .AND GUIDE.

Application filed March 2, 1925; Serial No. 12,470.

To (ZZZ whom it may COIZCFiL.

Be it known that 1, JOHN D. RAYMOND, a citizen of the United States, residing at Detroit, in the county of Wayne and State of hlichigan, have invented a new and useful Improvement in a Screw-Cap Retainer and Guide, of which the following is a specification. 7

My invention relates to a new and useful improvement adapted for mounting on a container having an exteriorly threaded neck surrounding the opening leading into the container and provided with a screw threaded cup shaped cap adapted for threading on the neck to serve as a closure. The invention is adapted for use generally for such a containerhaving such a neck and is particularly useful for mountingon tubes adapted for containing tooth paste and shaving cream or painters oils, colors and the like. It is the object of the invention to provide a means for moljmting on such a container which will serve to retain the cap when removed from closing position attached to the container readily accessible for use again as a closure so that the cap will not be mislaid or lost in the interim between the time of opening the container and the time of desire to close it.

Another object of the invention is to provide an attachment of this class which will serve as a guide so as to facilitate the placement of the cap upon the neck.

Another object of the invention is the provision of the spring-holder and guide of the class described which will be simple of structure, economical of manufacture and highly efiiciont of use.

Other objects will appear hereinafter.

The inventionconsists in the combination and arrangement of parts hereinafter described and claimed.

The invention will be best understood from a reference to the accompanying drawings which form a part of this specification and in which,

Fig. l is a side elevational view of the tube embodying the invention.

Fig. 2 is a fragmentary side elevational view of the tube showing the cap in section held by the retainer.

Fig. 3 is a fragmentary side elevational view of an automobile radiator showing the invention applied.

As shown in the drawing the container or tube comprises a main body 7 having an cxteriorly threaded neck 8 surrounding the opening formed therein. An interiorly threaded cup shaped cap 9 having the threads provided on the inner surface of the side walls 10 adapted for threading on the neck 8 serves as a closure. Secured to the upper wall 11 of the tube is a resilient piece of metal 12 having an angularly turned up wardiy directed portion 13 flared outwardly from the neck 8 at its end 14. The upwardly turned portion 13 is positioned in close relation to the neck 8 so that when it is'desired to thread the cap 9 on theneck 8, this portion serves as a guide to facilitate the proper registering of the cap with the neck so as to expedite the threading of the cap upon the neck. lVhen the cap is re moved from the neck the side wall of the cap is positioned between the neck and its upwardly dir cted' portion 13 as clearly seen in Fig. 2. hen the wall 10 of the cap is positioned between the outer surface of the neck 8 and the upwardly directed portion 13, this member 13 is flexed outwardly slightly from the neck 8 against the tension of the upwardly directed member 13 which is provided with sufficient resiliency to permit this flexing so that the wall 10 will be clamped between the neck 8 and the member 18. When the device is used for retaining the cap in the position shown in Fig. 2 the surface 'of the member 13 will. engage against the threads on the inner surface of the cap and this member 13 will press the outer surface of the cap into engagement with the threads on the neck 8 so that these threads serve to assist in affording a tight gripping of the cap.

In Fig. 3 I have shown the invention applied to the automobile radiator 15, having a screw cap 16 adapted for threading 011 the spout of the radiator. The mountings and use of the invention on the radiator is similar to the mounting and use already de ."cribed for the tube 7.

Havingthus described my invention what I claim as new and desire to secure by Letters Patent is set out in the accompanying claims, and I do not wish to limit myself to such structure as shown but desire to avail myself of such variations and modifications as come within the scope of the claims.

lVhat I claim is:

1. In combination with a container having an exteriorly threaded neck and provided Hii with an interiorl'y threaded cap for threading on said neck as a closure, a guide and retainer for said cap projecting in close proximity to said neck adapted for guiding said cap upon its initial positioning on said neck for a closure and adapted for engaging the side walls of said cap and clamping the same against the exterior of said'neck'for retaining said. cap in fixed relation on said 010- adapted for clamping said cap in close engagement with said neck when positioned between said stem and saidneck'.

3.. In combination with a container hav: ing a threaded neck surrounding an opening formed therein and provided with a cap. adapted for threadingvon said-neck as a closure for said opening, a resilientretaining stein projecting along side of said neckin spaced relation thereto, the space normally separating said stern and said neck being less than the thickness of the side walls of said cap, said stem being adapted for clamping the side wall of said cap into close. engagement with said neck upon the positioningofthe side wall of said cap between said stem and said neck, the free end of said stem being flared outwardly slightly from" said neck for assisting in guiding said cap in its initial threading upon said neck.

l. In combination with a container having an opening formed therein and a threaded neck surrounding same adapted for thereception of an interiorly threaded cap for a closure. for said opening, an L- shaped member mounted on said; container and having; one end thereof projecting up wardly in close proximity to said neck in spaced relation thereto, the space normally separating said stem and said neck being less than the thickness'ofsaid side walls of said cap; said stembeing adapted for clampingthetside wall ofsaid cap into close engagement with said neck upon the positioningof; the sidewall. oisaid cap between said stem and said neck,- the free end of said stein being flared outwardly slightly from said neck for assisting in guiding said cap in its initial threading upon said neck.

In testimony whereof I have signed the foregoing specification.

JOHN D. RAYMOND.
