HOLDER FORCOLLAPSIBLE TUBES Applicatioii filedfanuary ls,1928. Serial no. 247,500.

This invention relates'to holders for-cob lapsible tubes, such asare used forw' ending tooth 'paste,shav1ng cream and similar substances, and has particular reference to a portable holder with a service cover which will be automatically moved'to opened and closed positions.

Collapsible tubes of the above mentioned characterare provided with neck portions at their outlet ends which are screwthreaded for the reception'of a closure cap, and consider able inconvenience hasbeen found in removing and applylng suchscrew threaded closure caps, and frequently they are lost, making it necessary to subsequently leavethe tube uncovered. Anumber-of suggestions have been made with a viewto providing collapsible tubes=with captive caps,"but all o f such suggestions havebeen comparatively costly in 26 thatthey must necessarily be applied to the tubes by the manufacturers thereof, and furthermore, they have been objectionable, be

cause they were not'convenient for manipulation. V An important object of the present invention is to provide a portable holder for collapsibletubes'with a servicecover which can be very quickly, and in fact, automatically opened when the tube'is desired for use. So Another object of the invention is to provide such a device with means for automatically closing the service cover when the holder is replaced upon a shelf or other suitable supporting surface. i More specifically the invention contemplates the'provision of a holder which will support the collapsible tube in a substantially upright position and having a hinged cover to fit over the outlet end of the tube and ca- 70 4 pable of being swung away from the same for the'purpose of removing some of the contents there0f. A suitable counterbalance weight is associated with said hinged cover, so that when the holder is taken up for use, a slight tilting motion will result in automatically opening the cover, and connected with the same is a vertically movable rod, which, when the cover is opened, extends below the plane so ofthe'base of the holder andis adapted to be moved upwardly to close the cover, as will hereinafter be explained. V

Theforegoing and other objects, features and advantages of the invention will be more readily apparent from the following description, taken in connection with the accompanying drawings,-wl1erein one formof the invention has been shown by way of illustration, and wherein Figure 1 is ,a frontview of aholder having a collapsible tube'in place and with the hinged cover in closed position, v

Figure 2 is a side elevation of the same, Figure 3 is a view similarto Figure 2, but

showing the cover in opened position and the tube holding means in unlocked position,

Figure 4 is a fragmentary vertical transverse sectional view on the line ,4-l of Figure 2, V

Figure 5 is a horizontal sectional view on the line 55 of Figure 2; and

Figure 6 is a fragmentary sectional view ona larger scale taken on the lined-4) of Figure 2.

Referring now to the drawings in detail, it will be seen that the improvedholder l0 is in the'nature of an upright stand which is adapted to'support the collapsible tube 11 in substantially upright position, leaving the same accessible for themanual extrusion of so the contents thereof; The stand 10 which has been specifically illustrated, comprises a .pair of spaced parallel upright members 12,

which may be conveniently formed of tubing, and which are connected at their lower 8:;

ends by an integral laterally curved base member 13, and they are further connected at their upper ends by a similarly curved hori- I zontal portion l l, which, in this embodiment, functions to clamp and support the tube 11. 9o

Theupright members'12, at one side of the device, are provided intermediate the ends with a pair of spaced lugs 15 and 16 for connection of a pair of tube clamping elements 17 and 18 respectively. The tube clamping 9&-

element 17 may be formed of the same kind of tubing as is used for the members 12 and comprises a pair of parallel leg portions 19 which are adapted to be aligned with the upright portions 12 and which are connecte 10o together at their upper ends by a curved integral portion 20 which is substantially similar to the portion 1 lpreviously described. The lowe member 18 is similarly formed of tubular stock and has a pair of spaced parallel. leg portions 21 adapted to be axially aligned with the portions 19 and connected together intermediate their ends by a laterally curved portion 22 which extends in the opposite direction from the curved portions 13, and combines therewith in forming a supporting base for the holder 10.

The curved members 1-1 and 20 are so pro portioned as to be capable of firmly clamping the upper end of the tube body 11 in such a manner as to deflect the wall portions thereof and actually form a retaining groove from which the tube cannot he accidentally displaced, and the arrangement is such't-hatmanipulation of the lower clamping member 18 will result in operation of the upper clamping member 17 in such a manner as to lock or unlock the tube 11 in or from the desired position. For this purpose, the leg portions 19 of the clamping member 17 are pivoted as at 23 to the cars 15, and similarly, the legs 21 of the lower clamping member 18 are pivoted as at 2 1 tothe ears 1b. Extend ing upwardly from the extremities of said leg members 21 and movable therewith are a pair of pins 25 which engage within suitable slots 26 in the extremities of the leg p-ortions 19 between said pivotal connections 23 and 24. It will be evident, that by virtue of this arran ement, pivotal movement of the lower member 18 will result in a similar movement of the upper member 17 and preferably, a pair of spring clips 27 are secured to the upright members 12 adjacent the lower ends thereof and adapted to yieldingly engage the lower ends of the leg portions 21 in such a manner as to hold the parts in tube clamping position.

The spacing between the upright members 12 is preferably less than the width or thickness of the closed end 28 of the tube 11, and by virtue of this arrangement, it is possible to engage and firmly hold said lower end of the tube, as clearly shown in Figures 1 and For this purpose, the upright p rtions 12 are provided on their inner sides with transverse notches or grooves 29, within. which said lower end 28 of the tube is adapted to take a seat and to be held therein by the spaced leg portions 21 of the clamping member 18. if desired, a pair of dish-ed fin ger pieces 30 may be secured to the upright members 12 in such a manner as to overlie the hinge connections 15, 16, 23 and 24, whereby to conceal and protect the same and provide a convenient grip whereby the inner device may be lifted for use.

Carried by the upper end of one of the upright members 12 is a hinge connection 31 for a service cover 32, said cover being adapt ed to extend over the outlet end 33 of the tube 11, and preferably having a peripheral flange portion 34: which snugly fits against the inclined cover 35 of said tube. Secured to said cover in any suitable manner is a substantially rigid arm 36 on which is mounted a counterbalance weight 37, which, with respect to the pintle of the hinge 31, is disposed at the opposite side from the service cover 32. A longitudinally extending rod 38 is disposed within the upright member 12 with which the hinge 31 is associated; said rod being slightly greater in length than the height of the stand or holder 10. The upper end of said rod 38 is connected as at 39 to the arm 36 and its lower end is providedwith an oil-set portion 10, which, when the cover 32is in its open position, extends downwardly bclow the plane of the members 13 and 22, as best shown in Figure 3.

In the use of the device, the tube 11 is first placed in position between the fixed and adjustable members of the holder, whereupon the clamping members 17 and 18 are swung inwardly against the upright members 12 to effect the clamping engagement with the tube, as previously described. Thereupon, the screw threaded cap which is supplied vto the tubes by the manufacturers can be removed and if desired, discarded, and the holder 10 placed upon a shelf or other suitable support. In so placing the holder, the off-set portion 40 of the longitudinally moving rod 38 is forced upwardly, and such movement is transmitted to the arm 36, overcoming the influence of the Weight '37 and automatically moving the service cover 32 to its closed position, as shown in Figure 4.

It will be evident from the foregoing, that a tube holder of extremely simple construction has been provided, which will be of neat appearance and desirable, by virtue ofithe fact that collapsible tubes can be supported in upright position, occupying less space than is necessary when they are used as at the present time. The contents of the tube 11 can be very easily extruded, and the=user will not be required to waste any time or effort in removing and replacing a screw threaded cap, and the desirability of this feature will be very easily recognized by those familiar with the art. Obviously, the invention is susceptible of numerous modifications in the details of construction and arrangement of the parts, and the rightiis herein reserved to make such changes as fall within the scope of the appended claims without departing from the spirit of the lnvention.
