p INV TOR.

Filed Nov. .10, 1934 Patented Dec. 20, 1938 UNITED STATES PATENT OFFICE 17 Claims.

This invention relates to connecting devices and has particular reference to nonrefillable closures.

One object of the invention is to provide a de- 6. vice of the character described whereby the different members may be separate of each other so as to be separately interengaged.

Another object of the invention is to provide a device adapted to be locked and to be released in I an improved manner, as by a simple impact.

A further object of the invention is the provision of a device having relatively few and simple parts, and which can be easily assembled, and which is neat, compact, durable, reliable and con- 15 venient in use.

Other objects and advantages of the invention Will become apparent as the specification proceeds.

With the aforesaid objects in view, the inven- 25 tion consists in the novel combinations and arrangements of parts hereinafter described in their preferred embodiments, pointed out in the subjoined claims, and illustrated in the annexed drawing, wherein like parts are designated by .3 the same reference characters throughout the several views.

In the drawing:

Figure 1 is a fragmentary sectional view taken on the line l--l of Fig. 2 and showing a device embodying the invention.

Fig. 2 is a sectional view taken on line 2-2 of Fig. 1.

Fig. 3 is a top plan view of the closure member.

Figs. 4. and are fragmentary views in elevation of the device with the sealing member removed, and the projections thereof shown in dot dash lines, Fig. 4 showing the initial and Fig. 5 the locked position of the device and sealing member projections.

40 Fig. 6 is a sectional view taken on line 66 of Fig. 5.

The advantages of the invention as here outlined are best realized when all of its features and instrumentalities are combined in one and the same structure, but, useful devices may be produced embodying less than the whole.

It will be obvious to those skilled in the art to which the invention appertains, that the same may be incorporated in several different con- 50 structions. The accompanying drawing, therefore, is submitted merely as showing the preferred exemplification of the invention.

Generally described the invention provides a plurality of members movable relatively to each other in any suitable path, for instance, circularly. Extending between the members is a coupling means having movable engagement at different times, or along different paths, extents or directions, with the different members. In this manner, the coupling means may be utilized 5 for creating a force therebetween and the members for producing different effects. For example,

if the members he interengaged as by a cam, thread or equivalent arrangement, the means referred to may be moved first to actuate one of the 10 members to affect the cam or thread interengagement, as to tighten the same and subsequently the means may be moved to cause release of the coupling from one or both of the members,

as for removal of the coupling. The movable l5 engagements mentioned may be accomplished by elements adapted for lost motion connection. The advantages of the invention are best exemplified in a device wherein the coupling or like means is attachable to the members only when the latter are in a predetermined position relative to each other; for example, upon alinement of certain of the elements. In that case the elements on said means are movable into a position such that on moving the means to move one of the mem 5 bers, a disalinement is produced to prevent disengagement of the elements. While the invention is broadly applicable for interconnection between devices such as tubes, yet if the means be in the nature of an enclosure for the member that is moved to the end of the path of lost motion therewith, the enclosed member will be inaccessible for movement and will not respond to movement of the said means along its other path or direction, and hence the elements cannot be realined. Thus the removal of the said means cannot be effected, except as by breakage of the means or of one of the members. Such breakage of an appropriate part can be accomplished by actuating the means along the other path mentioned, and without disturbing the interengagement between the members themselves. The action may be described as involving lost motion engagement operative in opposite directions. If the interengagement between the members is not affected. or only in a negligible degree by movement therebetween, then the lost motion engagements may be operative in the same direction, the path for one extending beyond the path for the other. A possible construction may 5 include bayonet slots on the members and spaced projections on the means for engaging in the slots. But these parts may be reversed in position, between the means and members and between the means and only one of the members.

The spacing as between the bayonet slots may be insufiicient for the passage of a projection, which can thus pass only through alined parts of the slots, or else is locked if such parts are out of alinement. Since one of the bayonet slots may be wholly open at a top thereof, it is not necessary that the projections be alined with each other. While the projections may be fixed or integral in construction, they may also be removable and applied as desired. Then again, the frangible part, if one be used, may be broken by wedging engagement with one or the other of the members, and may also be broken by a different mode of operation involving broadly the application of an axial impact on the means or sealing member for wedgingly engaging a shoulder on one of the members, such sealing member having clearance and free or lost motion relation with the member therein, so that the latter and the connection between the same and the remaining member or container may not be disturbed or broken. Finally, it may be mentioned that the enclosed member may be regarded broadly as actuable by any relatively inaccessible means, whether a part of the sealing member or not, to produce the disalinement mentioned.

Referring in detail to the drawing, IE! denotes a device embodying the invention. The same may include a container or tubular member H, which may have an end portion or neck l2, at the base of which may be provided an annular wedge like shoulder l3. The said neck may be externally provided with connecting means, such as the cam or thread type I4. Below the tl'nead is provided an annular lip I5 having a plurality of angularly spaced cut outs l6, each communicating with a recess, opening or'channel H between the shoulder l3 and the lip l5. The respective openings H are angularly separated from each other by cam elements I8 all arranged in a corresponding manner.

A tubular or closure member l9 may coact in any suitable manner with the member ll, preferably by being connected thereto in a way that will permit relative rotation between the members. Thus the closure member may be engaged With the thread l4. A yielding gasket disc 20 may be provided in the closure member to engage the neck I2,

The closure member I!) may have angularly spaced external openings or recesses 2|, which are desirably of extended size horizontally and vertically, open at the top, and partially closed at the bottoms as by lips 22, providing cut outs 23 adapted to aline and communicate with the cut outs l6.

A third tubular, coupling, or sealing member 26 may surround or wholly enclose the closure member |9, preferably in coaxial relation therewith. The member 24 may have a top wall 25 spaced over the closure member, and may have a plurality of series of internal projections or lugs, each series including an upper lug 26 and a lower lug 27, arranged in a suitable manner so that the upper lug is receivable in an opening 2|. and the lower lug adapted to enter an opening through the cut outs I6, 23, in the alined position thereof. The upper lug is adapted to engage an abutment or edge of the opening 2| as at 28. The lower lug is of'such size as to be unable to enter the space between the lips I5 and 22 and is arranged so as to be adapted to engage the wedges l3 and l8.

In operation, the container H is filled with its desiredcontents and the closure. l9 screwed thereon reasonably tight, to a predetermined position, such that cut outs I6, 23 are in alinement. Then the sealing member 24 is applied as shown, with lugs 26, 27 positioned as in Fig. 4. Now the sealing member is turned to cause lug 26 to press on the abutment 28 to cause angular movement of the closure l9 from the initial position, with the cut outs I6, 23 out of alinement, as shown in Fig. 5. Hence the sealing member is locked in place by the lug 21, since passage thereof through the cut out 23 is blocked by the lips H3 and 22. To open the container, the sealing member may have a frangible part, such as that at the region of the lugs 21. For example, the sealing member may be made of a frangible material. Hence the sealing member may be turned in reverse direction, there being sufiicient clearance in the openings I] and 2| for the lugs 26, 27, and the lugs 21 caused to engage wedges l8 to fracture the frangible portion, so that the sealing member may be completely removed.

Another manner of removal of the sealing member is also possible. An impact may be struck the sealing member top wall 25, to cause the lower lugs 21 to engage the annular wedge it to cause a similar fracture of the sealing member for removal thereof. In either case, the breaking and removal of the sealing member does not affect the closure member, there being adequate clearance for relative movements therebetween.

It will be appreciated that various changes and modifications may be made in the device as shown in the drawing, and that the same is submitted in an illustrative and not in a limiting sense, the scope of the invention being defined in the following claims.
