SUPPORTING AND CLOSING MEANS FOR COLLAPSIBLE TUBES Hunter Reams, Hagerstown, Md. Application April 24, 1952, Serial No. 284,103 2 Claims. (Cl. 22018) This invention relates to new and useful improvements in holding devices for collapsible tubes and the primary object of the present invention is to provide a novel and improved means for releasably holding a plurality of collapsible tubes while retaining the discharge ends of the tubes closed and sealed, in such a way as to provide for greater convenience in the use of the tubes and for their neat and orderly storage when not in use.

Another important object of the present invention is to provide a supporting and closing means for collapsible tubes involving cap elements having means for tightly closing and sealing the discharge nozzle of a collapsible tube that is received within the cap element.

A further object of the present invention is to provide a collapsible tube having a modified nozzle end with interconnecting means between the nozzle and a cap element for camming and retaining the nozzle end in tight sealing engagement with a washer positioned in the cap element.

A still further aim in the present invention is to provide supporting and closing means for collapsible tubes that is extremely simple and practical in construction, neat and attractive in appearance, strong and reliable in use, efiicient and durable in operation, inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operations as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part thereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a front elevational view showing the present invention applied to the molding strip of a bathroom wall and holding a plurality of collapsible tubes in vertically inclined positions;

Figure 2 is an enlarged fragmentary vertical sectional View taken substantially on the plane of section line 22 of Figure 1;

Figure 3 is a fragmentary perspective view of the collapsible tube used in conjunction with the present invention;

Figure 4 is an elevational view of Figure 3;

Figure 5 is a detail sectional view taken substantially on the plane of section line 55 of Figure 2;

Figure 6 is a perspective view of the cap element forming part of the invention and with parts thereof verse apertures that accommodate fasteners 12, by the base member may be removably secured to a supporting structure, such as the molding strip S of a bathroom wall W.

Numeral 40 represents a collapsible container or tube whose neck neck portion 42. The lugs in cross-section and include 50 that meet at an apex 52.

position, the apices 5 flex slightly. Through this construction, as the cap elements are threaded into the recesses, the flat upper Walls 54 of the cap elements would bear against the end walls 18 to yieldingly retain the cap elements within the recesses.

It should also be noted that the surfaces of notches 30 that extend to meet surfaces 32 are inclined abruptly to a greater angle than the surfaces of the notches 30 that meet surfaces 34. This arrangement tends to prevent counter clockwise rotation of the tube for removal thereof from its cap element. In other words, the neck of the tube is held in the cap as the tube is rotated clockwise and the are received in the notches 30, the flat lower edges 40a of the tubes 40 will be aligned with one another as shown Patented Jan. 10, 1956' in Figure 1, or will hang in such other position or positions as may be preselected to provide the greatest convenience in the use of the tubes and the neatest and most orderly storage when not in use.

The cap elements 20 are preferably constructed of a resilient material, such as plastic, so that the nozzles 44 will be in tight scaling engagement with the seats 36 and the washers 38 and so that the

lugs

26 and 28 may flex downwardly slightly, as the tubes 40 are turned to the right, approximately one quarter of a turn, in order to remove the tubes from their holding caps.

The lugs 46, the

lugs

26 and 28, the abrupt ends of the threads or threaded ends 22, and the abrupt ends of the thread grooves in the sockets are so arranged relative to each other as to hold the tubes in-fixed, predeterminedpositions with respect to each other. T he device thus described will provide for greater convenience in use of the tubes, and for their neat, orderly storage when not in use.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a prcferred ernhodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claims.

Having described the invention, what is claimed as new is:

1. Supporting and closing means for the necks of collapsible tubes comprising an elongated base member attachable to a wall and having bottom longitudinally spaced threaded recesses -therein,-externally threaded caps for said necks rotatable in one and the same direction in said recesses for threading into the same, opposite notched cam lugs in said caps, and opposite lateral lugs on said necks rotatable over said cam lugs by rotation of said necks in said caps in said one direction and into and from interlocking engagement with the notches in said cam lugs, said cam lugs coactin g with said lateral lugs during such rotation of the necks to earn the necks inwardly of the caps, the threads in said recesses and those on said caps having terminal radial stop shoulders engaging upon rotation of said caps in said one direction to establish a like position of the cam lugs in the caps to thereby establish a like position of all of the tubes when the lateral lugs on the necks engage the notches in the cam lugs,

said lateral lugs during rotation thereof into disengaging position coasting with said notches to maintain s i shoulders engaged.

2. Closing means for the neck of a collapsible tube comprising a cap for said neck externally threaded for turning into a support by rotation of the cap in one direction, opposite notched cam lugs in said cap and opposite lateral lugs on said neck rotatable over said cam lugs into and from interlocking engagement with the notches in the cam lugs by rotation of said neck in said cap in said one direction, said cam lugs coacting with said lateral lugs during such rotation of the neck to cam said neck into said cap, the external threads on said cap terminating in a stop shoulder adapted upon turning of the cap into the support in said one direction to engage a stop shoulder on said support when the lateral lugs engage the notches in the cam lugs, said lateral lugs during rotation thereof into disengaging position coacting with said notches to turn said cap in said one direction whereby to engage the shoulder on the threads with the shoulder in the support.
