CAP.

Application led November 25, 1924. Serial No. 752,079.

My invention aims to provide an improved means for securing caps to the outlets of collapsible tubes, sprinkler tops and other receptacles. An embodiment of the -invention is illustrated in the accompanying drawings in which Fig. 1 isvan enlarged elevation of the upper portion of a collapsible tubewith a cap secured thereto in closed position;

Fig. 2 is an elevation from the right side of Fig. 1;

Fig. 3 is an elevation viewed in the same direction as Fig. 1 but showing the cap in open position; *Y Fig. 4 is a view showing the parts before their assembly; 1'

Fig. 5 is a detail view of an improved hinge member. l

Referring to the embodiment of the invention illustrated the collapsible tube is providedl with a screw threaded neck 12 having a retaining ring 14 screwed thereon. The cap 16 also engages the screw threads of the neck "12 but is provided with means whereby it cannot be separated from the tube 10 when fully unscrewed from the neck 12 thereof. The neck 12 is provided with a` plain cylindrical portion 18 and the retainer tending flange 20 which is adapted. to limit the endwise movement of the retaining ring so as to prevent its being unscrewed entirely from-the cap, the iange 20 beingl The cap 16 is hingedly secured to the re-I I taining r1ng.14 by an improved connecting member comprising a hinge link 24 of substantially lrectangular shape as -shown 1n Fig. 5. This link is rovlded with lplntle portions 26 and 28 whlch are connected by leg members 30. The cap 16 1s formedwrth an outwardly extending lug 32 whlch 1n its initial stage of manu acture extends straight outwardly as illustrated in Fig. 4.

The retainer ring 14 is formed with a similar outwardly extending lugv 34. In assembling the parts the hinge link.24 is slipped over the outer' ends ofthe projections 32and 34 and the latter are bent around as indlcated at` 36 and 38 so as to form plvot bearmgs for the pintle portions 26 and 28 respectively of the hinge link 24. The length of the pro- ' ections 32 and 34 is such that when the l are nt' around tothe position shown 1n 1g. 1

greater freedom of Amovement between the cap and the retaining ringl and'enables the formation of a hinge connection without the necessity of drillingholes in either the cap or :the retaining ring. This is an im ortant consideration in manufacture of articles of this class in which the cost of the container must be kept to a minimum. A further advantage of connecting the cap to the retainer ring by means of a floating hinge link is that such a connection makes it unnecessary to form the parts with extreme accuracy in order to permit the cap and the retaining IlIl nec It willbe appreciated that the floating hinge link described will permit the cap to have considerable lateral play rela-f the cap with those of the threaded neck of to be aligned with the screw threade the tube. It will Vbe readily apparent thatv if the cap were secured by a rigid hinge pin to the retainer that the relationship of the parts must be very accurate in order that they can be properly screwed onto the neck of the tube. With this in mind it will be appreciated that extreme accuracy would be required in locating the holes' for the rigid pintle pinsof an ordinary hinge connection. On the other hand, because of the play alllowedby the employment of a floating hinge link as above described it is appreciated that extreme accuracy in manufacture is not nec'- essary and hence the cost of producing caps according to m vinvention is materially less than the cost o manufacturing caps heretofore used.

Though I have describedfwith great particularity of detail certain embodiments of A Vthe invention, it is not to be understood therefrom that the invention is restricted to the particular embodiments disclosed. Various modifications in detail and in the arthose skilled in the art without departure from the invention as defined in the followin claims.

at I `claim is;

cap adapted toY be screwed. thereon, a retam- .105 rangement of the parts may be Ymade byv er swivelled onsaid container, and a hinge link having spaced pintle portions pivotally engaging integral projections formed on the cap and retainerrespectively.

2. A container having a threaded neck in combination with a. cap screwed thereon, a retainer swiveled on said neck adapted to permit the cap to be swung to open position without detachment and a hingev member having spaced pintle portions engaging the cap and retainer respectivel 3. A container having a, threaded neck in combinationwith a 'cap screwed thereon, a retainer swiveled on said neck adapted to permit the cap to be swung to open position without detachment and a hinge link of Substantially rectangular form having portions. forming spaced pintles, and lugs formed on said cap and said retainer bent to engage said pintle portions, substantially as described.

In witness whereof, I have vhereunto signed my name.
