WISCONSIN" HOLDER Application filed April 4,
This invention relates to closure controls and has special reference to a control or tether for closures such as used upon collapsible tubes or the like.
The principal object of the invention is to produce a more practical and efficient device of this character.
Another object is that of simplicity and cheapness of construction.
Further objects and advantages of the invention will appear in the following description thereof.
Referring now to the accompanying drawings, forming part of this application .and wherein like reference characters indicate like parts:
Figure 1 is a perspective view of one form of our improved tether as applied to a collapsible tube;
Figure 2 is a modified form of same; and
Figure 3 is a plan view of the tether and its attachment shown in Figure 1.
1 represents the cylindrical neck of a common collapsible tube such as used for tooth paste or the like, having a screw threaded closure 2 mounted thereupon, and in this instance I have shown the closure 2 as being provided with an annular recess thereabouts, and within which recess is loosely mounted the cylindrical portion 3 of the. tether, the ends of the wire forming the tether, which is obviously of spring wire construction, being shown as crossing each other and turned at right angles forming the spaced depending portions 4, which, still nearer their extremities, are bent backwardly upon themselves and then at right angles towards each other, forming the axis upon which the tether is pivoted; these two inwardly bent ends being shown at 5 and mounted within the fixed lug 6 formed upon the side of the cylindrical neck 1 of the tube.
It is apparent that by this construction the closure 2 may be readily turned in either direction without in any way interfering with the tether, it being assumed that the annular groove about the closure is of suflicient width to permit of the necessary raising and lower ing when screwed on or oil', and that the portions 4 of the tether projecting below the 1928. serial No. 267,410, Y
pivotal connection thereof will normally remain parallel with the walls of the neck of the tube, but if the closure is tipped away from the mouth of theopening the tether will pivotallyconduct same simultaneously with the extremelower ends of the portions' lfric-v tionally contacting the arcuate sides of the neckl. By this contact of thelower ends'of the portions 4 of the tetherthe closure is biased both in its closed and in its extreme open position, the portions 1 readily yielding from or towards each other as their extreme lower ends are pressed outwardly by engage ment with the arcuate walls ofthe neck of the 2 tube, or brought towards each other by their closing'sprin action.
In Figure 2 we have shown aslightly modi-.
fie'd form of both tether and closure cap, the
latter being provided with an enlarged anis installed in lieu of being externally of the capv as shown in Figure 1.
The'depending ends 10 of the wire forming the tether are bent downwardly and spaced apart rather than overlapping each other as shown in Figure 1, then bent at right angles outwardly away from each other forming the pivotal connection through spaced lugs 11 upon the wall of the cylindrical neck of the receptacle. Externally of the lugs 11 the termini of the wire are turned downwardly at right angles and then back upwardly upon themselves forming a dependlng neck engaging portion similar to the depending portions 4 of the tether shown in Figure 1 and which engages the sides of the cylindrical neck in the same manner as those illustrated in Figure 1 and for the same purose. p In this modified form, however, it will be noted that thenormal tendency of the ring 9 of the tether is to contract, thus freeing its frictional engagement with the cap simultaneously with the biasing effect of same both in its opened and closed positions, while in the construction shown in Figure 1 the termini of the wire also normally tend towards each other and the effect of the ring 3 is that of being opened and likewise freeing its frictional contact with the cap or closure.
From the foregoing it is evident that we have devised an exceedingly simple wire tether for the closure of areceptacle and one 'Which prefera'bly is made to cooperate with the peculiar shape of the receptacle adjacent the opening therein.
Having vthus described ourinventiomwhat we claim and desire to secure by Letters .Pat-: 7 n it ent, is:
1; An internally the type described having an inwardly flanged extension aboutth'e op'enicircumferential edge thereof, a circularspring control wire removably mounted within the exten Q sion and pivotally attached to a container externally ofthe-closureQ QIT'hecQmb inatiOn' with a receptacle havr ing a screw threadedly mounted cap therefor,
of an annularrecess internally .ol'the open aface ofuthe cap, a control for :salidcap comprising-a spring wire having :a yieldable circular portion fitting within the recess-infihe ca-p,thelopposite extremity of the vvire being pivotally-attachedto the receptacle. I
3.rIn combination a receptacle having a closure therefor, a tether for the closure comprrsing' a spring wire 'havingraportion 'cooperatively engaged with'the closure, an op- .p-osite portionpivotally engaged withapora tion .of the receptacle and means externally of the pivotal connection for engagement with portions ofthetether for causing a stress therein when moved in opposite directions. i g V [In testimony whereof we aifix our signatures. .7 Y 7 7 JOHN A.
