Aug. 7, 1951 H. RAYMOND COUPLING DEVICE Filed Feb. 25, 1948 Patented Aug. 7, 1951 COUPLING DEVICE Henri Raymond, Guissalles by Vindelle, France Application February 25, 1948, Serial No. 10,844 In France March 2'7, 1947 3 Claims.

1 In the closure of bottles and flasks in particular those used for containing drugs and the like,

covers or caps are used which are generallyformed of plastic material and which are adapted to seal the mouth of the bottle through the compression of a rubber or an agglomerated cork disk. Moreover such caps are formed with an inner screw-thread adapted to engage a complementary thread formed around the upper portion of the bottle neck.

However a large number of bottles or flasks do not comprise such a screw-thread and the top of the neck terminates in an outer flange or shoulder portion. The means used so far for obtaining a tight seal for such containers generally make use of a cork stopper or the like retained in place with string, wire or similar means.

- An object of my present invention is to provide a coupling device whereby screw-threaded caps may be mounted on bottles, flasks or other containers of any type. It is further applicable in other connections as in the coupling of two pipe elements for example.

Other objects and features of the invention will appear from the ensuing disclosure made in reference to the accompanying drawing wherein:

Fig. 1 is a vertical cross-sectional view of a coupling device according to my invention, as applied to the closure of a bottle, the cross-section being made on line II of Fig. 2.

Fig. 2 is a view in horizontal cross-section on line IIII of Fig. 1.

Fig. 3 is a view in axial cross-section on line III-III of Fig. 4, showing a device according to the invention as applied to the joining of two pipes.

Fig. 4 is a view in transverse cross-section on the line IV--IV of Fig. 3.

In the exemplary embodiment of my invention as shown in Fig. 1, the device is mounted on the neck of a bottle I. The top of the neck is formed with an outwardly projecting flange or shoulder 2 the under face of which is adapted to abut an outwardly screw-threaded ring formed of two parts 3 and 4 separable lengthwise thereof. Said parts 3 and 4 are connected and held in such condition by means of two lugs 5 and 6 adapted to be gripped when mounting the device.

The threaded ring in this position is ready to receive thereon a cap I inwardly screw-threaded so as to engage said threaded ring. Said cap carries a rubber or agglomerated cork disk 8 applied against the inner end wall of the cap (Fig. 1).

The outer portion of the cap is formed with 2 castellations 9 to facilitate an efiicient clamping engagement thereof around the threaded ring (Fig. 2).

To mount the device on a bottle, the user maintains both parts 3 and 4 of the threaded ring applied against the neck of the bottle I by means of the lugs 5 and 6, the ring being positioned against the under face of the shoulder 2 of the neck. It then only remains to screw the cap 1 provided with its cork-disk onto the threaded portion of the ring so as to obtain a tight and perfectly safe seal.

The closure device thus produced forms a unitary assembly adapted to be quickly and cheaply manufactured to provide solid and rugged units adapted to be delivered for sale as easily as the ordinary threaded caps.

Moreover, with range of gauges progressively varied according to the size of the screw threads and the diameter of the bottlenecks, it will be possible to provide a closure for flasks and bottles of all sizes and even certain types of jars.

The use of a sufficiently resilient plastic material such as Celluloid makes it possible to produce a unitary ring member which will simply be slotted along one side thereof so as to enable it to be distended as required.

My device has the further advantage of being adapted to replace the various strap closure means used so far for preserves in bottles or jars.

In the futher use of my invention illustrated in Figs. Sand 4, two tubes l0 and II, threaded (not necessarily with a common pitch) at their ends, are connected together through the device which herein comprises a nut ring member separated in two parts I2 and I3. Said nut ring member is bored at its upper end to the diameter of the tubes to be joined. The inner recess is provided with a screw thread It on which is engageable the pipe II, the top of said ring engaging the shoulder formed by the thread of the pipe H3 or alternatively a groove formed on assembly by means of a. suitable tool. A seal 15 is interposed between the pipes to ensure a tight seal after the ring is clamped thereon. The parts I2 and I3 are strongly pressed against each other by means of a clamp or collar H5 housed under the castellations ll of the ring so as to be prevented from sliding, and said collar being secured to said ring by means of a bolt l8 which is adapted to strongly clasp the collar only after the ring has been completely screwed onto the pipe I l.

The invention is not limited to the forms of embodiment described and illustrated which have been given merely by way of example. Without exceeding the scope of the invention, various modifications may be made in the details thereof. Thus in the pipe 10 of Fig. 3, the inner flange of the ring l2-| 3 could be made to engag a shoulder formed in any suitable way of the pipe I0. The lugs 6 in Fig. 1 or castellations 11 in Figs. 3 and 4 could be replaced by projecting elements of any suitable form adapted to make it easier during assembly to holdiboth parts comprising the connecting ring 3, 4 or I2, 13.

What I claim is:

1. A coupling device for coupling two pipe elements a first one of said pipe elements having, an.

external screw thread at the coupling end thereof and the other element havinga'peripheral radial projection adjacent the coupling; endthereof,

comprising a ring member internally threadedl throughout a portion of its length andadapted to threadedly engage said screw-thread of said saidring being divided REFERENCES CITED The following references are of record in the file; of this-patent:
