GLOS'URE FOR CNTAINERS Appiiation. med `July 24,

Collapsible tubes intended to contain toothpaste, shaving cream, c old cream, vaseline, Vand other paste-like or semi-Huid materials have commonly been provided with detach- 5 able screw caps. Caps of this character have to be removed to of the tube and such Caps are frequently dropped and lost or mis-placed, beside which theyv are l'diiiicult Vto screw on accuratelyand easily because the threads become crossed in attempting to replace the cap. Y

yThe object'o my invention is to provide an improved cap for use on any collapsible tube or like containers, such as commonly einployed for containing and dispensing toothpaste, shaving cream, cold cream, vaseline, and other semi-liquid ingredients, which will be adapted for opening and closing in a semiautomatic manner, when manipulated by the user, without possibility of detachment of the cap from the neck or nozzle of the collapsible tube. -A

My invention insures against loss or misplacing the cap and also insures 'rapid and easy opening and closing thereof, while afording a tight and'satisfactory closure which y prevents the escape of the contents of the collapsible tube, when the tube is packed in a traveling bag or othery container with other articles, and at other times.

It will be understood that the principle involved in the present invention is not limited to use in connection with collapsible tubes and to illustrate the use of the device in'oth er connections, I have shown and described hovv the invention may be usedas a cap for an automobile radiator. Other uses will be apparentsfrom the following description of the in- 40 vention. f

'adapted to telescope over the outer end 6 of 1931. Serial No. 552,987,

Fig. 5 is a plan view of the ring employed in connection with the form shown in Fig. 4; and Y Fig. 6 is a part side elevation, part sectional y view showing the invention applied to an automobile radiator nozzle.

The collapsible tubeto which my improved cap is shownas applied, appears at 1 and has a neck or nozzle 2 which is provided in its end V with an orifice 8 through hich the toothw paste, shaving cream, col-d cream or the like maybe extruded on pressing the tube 1, as usual.

The neck or nozzle 2 is provided with a rib 4 extending longitudinally *thereof and ter- 65' minating at acircumferential flange 5 located near the end 'of said nozzle, leaving a' free end part 6 on said nozzle which is adapted to enter the improved cap.

The guide key rib 4 has a cross notch or indentation? disposed near the outer end of said-rib to co-operate with means on the improved cap. The walls'of the notch 7 arek tweenthe notch and the ange 5, the purpose of which will be described later. The inner end of the rib 4 may extend to the shoulder 8 of the tube l, as shown in Fig. 1, or said rib may be provided with a shoulder 9, as shownl in Fig. 2, the purpose of these constructionsl being to arrest 1the operating ring for the cap during the opening ymovement of the device.

Sli'dable on, and snugly iitting the neck or rnotch 11 that receives the rib 4 so that dur- 85 ing the sliding niovementsof the ring '10,' said ring is guided on the tube, prevented from binding thereon, and the swingfor the cap is therebydirected to the notch v7. 90

f A cap 12 has a short lever or arm 13V which is pivoted to the ring 10 by a wire or pin 14 whose ends are held in holes 14 drilled in the ring, as shown by dotted lines in Figs. 3 and 5. Lever 13 hasan extension or toe 15 95 which is adapted to enter the notch 7 when the ring 10 ismoved almost to the outer end of the nozzle 2, for the purpose of camming the cap 12 down into position where it is 10e the nozzle. The lower face of the toe 15 is curved at 15.

The lever 13 has a surface 16 which is adapted to slide or ride on the face of the rib 4 when the ring is drawn toward the tube l. This sliding action positively hol-ds the cap 12 parallel to the nozzle 2 and out oi'. the way so that the dispensing end of the nozzle can be used. VJ hen the ring 10 is drawn outwardly, the tip 15, and the curved face 15 of the lever, due to engagement with the wall of the notch 7, cam the lever and swing the cap 12 downwardly to close the dispensing end of the nozzle; that is to say,-the reciprocating movement given to this manipulative ring causes the cap to be alternately actuated into and out of its closure position.

The cap is of shell-like construction and adapted to telescope over the end 6 vof the nozzle. i

Preferably, there will be provided a suitable cork inner face or gasketl? or'the cap to eiiectually seal the end of the nozzle.

It is desirable to provide a snap catch or locking device to hold the cap 12 in closed position. Such device may comprise a nib 18 on the part 6 and an indentation 19 on the cap.

Then the cap is closed, it preferably rests against the outer face of the flange 5, which ange also serves as a stop when the ring 10 approaches its oi'itermostor extreme travel position, as previously explained.

A suitable linger piece or projection 2O is provided on the cap to enable it to be readily released prior to sliding the ring 10 toward the tube 1. lll/*hen the slidable ring 10 is placed intermediate either of its extreme travel positions, the toe 15 will ride on the top face of the key 4 and thus int-erlockingly hold the hinged cap 12 against tilt around its pivot 14.

In Figs. 4, 5, I have illustrated the manner in which an additional rib 2l may be provided on the nozzle or tubular neck 2, in diametrically opposite disposition to the rib 4 for the purpose of balancing the ring to lessen the tendency ot the ring to bind on the Vnozzle 2. The i'ing 10, if such construction be employed, will have an internal notch 22 to slide on the rib 21 ust as the notch 11 slides on the rib 4. Y

In Fig. 6, I have illustrated the manner in which the principle of the invention may be applied to the nozzle or nipple of an automobile radiator, for while I am aware that present-day practice calls for flat caps for automobile radiators, nevertheless the present invention is well adapted for use as a quick-opening and closing radiator cap. The only change which need be made is to provide on vthe interior of the device an in* ternally screw threaded ring or part 23 which will -screw on the threaded nipple on the radiator, said nipple being receiver within the tubular part 24, which corresponds to thenozzle 2. In this form of the invention, the

construction is the saine as previously del "will serve as a closure for the orilice of the nozzle, or, for disposition in open position relative to said nozzle-orifice.

2. In a closure 'for the nozzle of a container, the combination with a nozzle having a.

longitudinal rib, ot a ring slidable on said nozzle and being guided by said rib, said rib being provided with a camming notch, i

and a cap provided with a lever hinged to said ring and bodily carried by, and shiftable with, said ring, said lever having a part which is in contact with the rib and maintains the cap alongside the nozzle when the ring is retracted, said lever being provided with a projection which is adapted to cooperate with said camming notch to eliect opening or closing of the cap when the ring is in a given position of its travel. l
