2 Claims. (Cl. 229-7) The present invention relates to containers for liquids and it is particularly adapted for milk containers which are customarily made of cardboard. The speciflc object of the invention is to provide a pouring opening with closure means of special type incorporating a hinged element carried by the top wall of the container, and, in closed position, lying flush with said wall, to gether with a disk-like member which is adapted to immediately close the pouring opening of the cap and therefore is of the same diameter. This disk-like member is so initially related to the container top wall that when the closure is raised for the discharge of liquid, the disk-like member is automatically and slightly deformed so that it will have a satisfactorily tight frictional engagement with the wall of the pouring opening when the cap is again closed.

The invention will be described with reference to the accompanying drawings, in which:

Fig. 1 is a perspective view of a container constructed in accordance with the invention;

Fig. 2 is a vertical and fragmentary section on the line 22, Fig. 1;

Fig. 3 is a composite view in perspective, showing, partly by dotted lines, the upper area of the container and the two members of the end wall which include the hinge closure and the disk-like pouring opening closure;

Fig. 4 is a slightly enlarged transverse section on the line 4-4, Fig. 3;

- Fig. 5 is a fragmentary view showing in top plan the closure disk carrying member;

Fig. 6 is a schematic fragmentary view generally on the line 2-2, Fig. l, and schematically showing the action of the parts when the hinge closure is partly lifted, breaking away fragile webs which hold the periphery of the closure disk to the member which initially carries it;

Fig. '7 is a view similar to Fig. 6, showing the container with liquid pouring therefrom and the closure raised;

Fig. 8 is a perspective view partly broken away showing the closure raised from its position in Fig. 1;

Fig. 9 is a view in sectional elevation through the top area of the container after the closure has been restored to closed position; and

Fig. 10 is an enlarged fragmentary vertical section on the line III-I0, Fig. 9.

Referring to the drawings, I have shown at I the body of a rectangular container which may be constructed of any suitable web material, as for example paper board. This container will be closed at its bottom end by any suitable means,

such as by an applied cap Ix. or by integral flaps as in many box constructions. At its upper end the container will be closed by a cap, enerally indlcated at 2, which cap is of special construction. v

In the form shown, cap 2 is constructed from a blank provided with four wings 2a: which are adapted for folding downwardly to provide flanges for location within the body of the container I.

Cap 2 is provided with a primary closure 3 hinged at 4 by a score line, the closure being bounded by semi-circular cuts 6 which are very slightly spaced from the hinge line, or lead directly thereto. As shown in Fig. 3, the cut lines 6 lead to weakened lines extending downwardly in one of the flanges 2:: and joining a cut-out at in.

The disk closure carrier is, in the present embodiment, a sheet of paper board 8, folded at one margin to provide a depending flange 5, and formed with a plurality of semi-circular cuts at 8:1: bounding the disk-like closure 1, the cut 6 being spaced from each other only sufficiently to provide webs of little resistance to tearing the disk away from its holding sheet but sufficient for the purpose hereinafter to be described. The

disk closure carrier will be cemented or otherwise secured to the underface of the cap 2 with the proviso that the disk-like member I has its cementing area spaced from the periphery of the disk, as indicated at Ix, Fig. 3, for the purpose hereinafter to be described.

Again considering the disk-like closure member I, it will be seen by reference to Fig. 5 that within its periphery it is formed with a rectangular score at 11:, the areas outwardly of the score being wing-like in character.

It will be seen that a cut-out 2m: will lie in registration with a cut-out Izod: in the container body I, and that from cut-out lxa: to the upper edge of the container wall are formed weakened lines 10.

Reference to Fig. 6 will show an initial raising of the closure member 3 and that it will carry with it the disk-like closure 1, the latter breaking away at the web areas immediate the semicircular cut lines 8:0. Inasmuch as the wing-like areas are directly affected by the resistance afforded by the fragile webs of the paper board between the semi-circular cut 6, they will be deformed, that is to say, slightly pulled down, and being deformed, the peripheral area of the closure disk I will no longer exactly fit the hole formed in the disk carrier when the disk is a,sss,211

3 broken away therefrom. Thus when fluid poured from the open container and the closure is restored, the slightly deformed disk will have sufllcient frictional engagement with the wall of the pouring opening to adequately maintain the closure in position, and the container may be satisfactorily tightly closed after a repeated number of pouring operations.

Having described my invention, what I claim and desire to secure by Letters Patent, is as follows:

1. A container for fluids and other materials consisting of a body closed "at its-base. a closure for the upper end of the container consisting of a flanged sheet formed with a closure member by spaced cuts at opposite sides of a hinge line, the closure having a cap-like portion extending downwardly into a flange of the sheet, and said portion being bounded by weakened lines, a second sheet underlying that flrst named sheet and having'a closure disk area secured to the underface of the closure of said flrst sheet, said second sheet having a depending flange disposed inwardly of the said flange of the first sheet and covering the weakened lines therein, and the disk being secured to the closure member of the first sheet in such manner as to provide at least areas, and a wall of the container body is formed,

with a like aperture. the two apertures being in registration, and the container body having opposed weakened lines leading upwardly from its aperture to the top edge of the container, as and for the purpose set forth.
