Application August 3,

2 Claims.

This invention relates to containers, such as milk bottles, which are provided with hoods to protect the mouths of the containers from handling. One object is to provide, in combination with a container having an external top lip forming an abrupt underneath shoulder, a hood thereon of the class comprising a crimped-skirted cap and a band banding the hood-skirt and the band whereof shall so coact with and be rem lated to said shoulder as to firmly secure the hood against slipping off the container and which hood shall be so constructed that it may be readily removed from the container by a novel manual operation and without disassociation or appreci able disturbance of the relation of the cap and band to each other. Another object is to provide a hood of the indicated class which may be manufactured at little expense; be nested with others in quite compact order; and be readily applied by a single pressure operation involving only a contraction of the hood into gripping relation to the container and with the use of a simple form of attaching appliance.

In the best form, the skirt or the cap is crimped in a definite way, to wit, with box pleats, which it is found permits the expansion of the skirt to be efiected more easily and uniformly than when the skirt is crimped indiscriminately or even with simple pleats.

The band may be secured to the skirt in any way at substantially equally spaced points circumferentially thereof. Thus, if it is a fiat band, by forming spurs or cleats therein which penetrate the skirt and are clinched to it. Or it may be secured to the skirt by a fillet of paper or other flexible material covering it circumferentially and glued or otherwise secured to the skirt.

In the drawing,

Fig. 1 is a side elevation of the hood before application to the bottle;

Fig. 2 is a view similar to Fig. 1 with the hood applied to the bottle;

Fig. 3 is a view similar to Fig. 2, illustrating the manner of withdrawing the hood;

Fig. 4 is a section on line 4-4, Fig. 2;

Fig. 5 is a fragmentary section on line 5-5, Fig.

Fig. 6 shows a modification; and

Fig. 7 is a side elevation of the top of the bottle. The bottle 1 has the conventional top lip 2 formed with an abrupt shoulder at 3. 4 is its sealing cap.

To form the cap 5 a disk of paper of the weight a or stock commonly used for bottle hoods now em- 1933, Serial No. 683,494

ployed is by suitable means developed to the truncated conical shape shown by Fig. 1, thus to produce a top disk portion 5a and 2. depending conical flaring skirt 5b. The skirt in the operation of forming the cap becomes crimped and this crimping is so performed that in horizontal section a number of box-pleats 6 (Fig. 7) are developed.

Having the cap thus formed a non-resilient band '7, as of thin easily pliable, non-resilient metal, is fitted over and secured to the skirt. It being an important feature of our invention that the band should take under the abrupt bottle shoulder 3 when the hood has been applied to the bottle the position of this band should be such that when it is thus fitted over the cap its top edge will stand in approximately that horizontal plane which is distanced from the top 5a of the cap approximately the same as the shoulder is from the top of the bottle, so that it will bend the skirt underand against the shoulder, as at in Fig. 2, when the assembly of bottle and hood is complete.

Either the band element or the cap element may have means to secure the band element to the skirt against axial displacement relatively to said skirt. Thus in the form shown by Figs. 1 to 5 the band element has cut-out cleats or spurs 8 which are bent inward so as to puncture and clinch the skirt. And in the form shown by Fig. 6 the skirt of the cap has a flexible fillet or strip (as of stout paper) which circumferentially embraces the band and, being wider than the same, is glued at least below, and preferably also above it, to the skirt.

In any event, the skirt of the cap should be of such depth that when the band is in place the skirt will extend an ample distance, as shown, below the band so as to permit the thumb or forefinger to be entered between the skirt edge and the bottle and a firm digital grip obtained on such edge.

The improved unitary hood, comprising the cap and the band permanently united, is applied to the bottle by tapping the bottle therewith and then, by a suitable appliance, contracting the band and hence the skirt and so that the band will take under the shoulder 3 of the bottle, in which operation crim-ps 10 will be formed in the band at various points. The effective operation of the tool without its incidentally displacing the element 7 downwardly with respect to the cap is insured by shaping said element to a form which is conical in the same direction as the cap-skirt.

To remove the hood the consumer inserts his finger or thumb between the bottle and the skirt Bill edge and pulls radially on the skirt to expand it and hence the band (repeating this operation at other points around the bottle if necessary) and then by an upward pull slips the hood with the band, which remains attached to the cap, off the bottle.

Having thus fully described our invention what we claim is:

l. The herein described generally symmetrical frustro-conical unitary hood for a container having a top external lip forming an underneath shoulder, said hood comprising a flexible cap element having a substantially conical flaring skirt and, in a zone removed from the lower edge of the skirt and to be below said shoulder when the cap element rests on and in capping relation to the container top, a non-resilient pliable element completely encompassing and snugly fitting the skirt and itself substantially symmetrical and of uniform strength, one of said elements having at substantially uniformly spaced points circumferentially of said elements means to secure the band element to said skirt against axial displacement relatively to said skirt and said pliable element, when the hood is placed in capping relation to the container, being adapted to be crimped and thereby contract said skirt below said shoulder to less diameter than the latter and being also conical in the same direction as the skirt.

2. The herein described unitary hood for a container comprising a flexible cap, a non-resilient pliable element completely encompassing and snugly fitting the cap-skirt, and a flexible fillet extending around the skirt and overlying said element and secured to the skirt at the side of said element adjoining the free edge of the skirt.
