Description

D. DA RO LD March 28, 1939.

CONTAINER Filed Oct. 23, 1937 Sil f l a 'fl'.ll ...IIJIIIIII'I'IIIIIII/ Patented Mar. 28, 1939 UNITED STATES CONTAINER Duilio Da Rold, Milan, Italy, assignor to Heinrich Hermann Heer, Zurich, Switzerland Application October 23, 1937, Serial No. 170,685 In Italy October 26, 1936 3 Claims.

The present invention relates to a hermeticallysealed container for powder and for plastic substances and for other substances made of pulp, paper, card-board or similar material.

The invention isvapplied preferably to containers which are required to be air-tight and impervious to moisture.

The invention relates more particularly to a container in which the one end of the container forms a replaceable cover. According to the invention the cover is provided with a flange or skirt portion adapted to fit tightly into the open end of the container. The upper edge of the body of the container and the margin portion of the flange of the cover are tightly connected either by beading one part over the other or otherwise, forming a perfect tight joint. Near the end cf the container a line of weakness extending around the container is provided. By breaking the line of weakness the cover may be taken oi and may be used again for Closing the container, part of its skirt entering the body of the container.

An essential feature of the invention resides in the closure of the container and apart from the cover and those parts of the container which are necessary for the closure system, the container may be of any suitable construction.

In the accompanying drawing there are illustrated by way of example two preferred forms of construction of the invention.

Fig. 1 shows an elevation of the closed container.

Fig. 2 is a vertical section of the container.

Fig. 3 shows in side elevation the open container with the raised lid, which isheld at the edge.

Figs. 4 and 5 show an elevation and plan of the member for opening the container.

Fig. 6 shows part of a second form of construction in sectional elevation.

The container shown is of cylindrical shape, it is provided at the upper end of its wall I with an inwardly directed shoulder or rib I0. The rib I0 supports a cover 5 consisting of a disc of cardboard or similar material. The cover 5 is guided in the upper part of the container I by a skirt I5 which nts closely into the upper part of the container. At about half the height of the skirt I5 a line of weakness is arranged in the wall of the container, which may be formed by a row of small perforations or slots 2. At a suitable point a pulling or opening member 3 is arranged.y This opening member 3 is shown in detail in Figs. 4 and 5. This opening member 3 is formed by a narrow strip 3 of paper cardboard, metal or synthetic material, and is provided at the middle with a tongue 4. The latter projects through an aperture 'I in the wall of the container I. When closing the container I the strip 3 is placed between the inner wall of the container and the outer wall of the skirt I5 of the cover 5. Subsequently the upper edge of the container is bent inwardly over the marginal portion of the skirt I5, as is shown in Fig. 2. In this manner the container is iinally closed.

In order to open the container it is sufficient to .grip the tongue 4 and to pull this upwardly. As a result a pull is applied to the upper edge of the container along the Whole or nearly the Whole of its periphery. The upper part i2 of the container I is thus broken from the lower part along the iine of weakness 2. The cover 5 may be disconnected wholly or only partly from the lower part of the container. For example should it be desired to have the cover I2 connected to the container I by a portion of the skirt I5 the line of weakness 2 does not extend around the: entire periphery of the casing or is interrupted for a short distance for example diametrically opposite the aperture l. In this case the cover I2, as shown in Fig. 2, remains connected to the container I the connecting part forms a hinge II.

Another form of construction in accordance with the invention is shown in section in Fig. 6. This differs from the construction above described in that the tongue 4 is rigidly connected or is formed integral with a thin rotary disc 8 located under the cover 5 and resting on the shoulder I0. This disc 8 thus replaces the strip 3. The remaining parts of the container, especially the line of weakness 2, aperture I and so forth are the same as above described in connection with Figs. l to 5.

The arrangement may also be such that an` appliance for cutting open the seam formed b-y the holes 2 may be placed into the rim I5. The appliance may be secured thereto in a readily detachable manner and when constructed as a cutter can be used for cutting open the container around the holes 2.

The opening member may have various shapes but it is preferably attached to the container and so constructed that the cover will be torn loose from the container when a moderate pulling strain is applied.

What I wish to claim is:

1. In a container of cardboard, paper or the like comprising a container body and a cover provided with a flange adapted to be fitted into said body, said body having a weakened portion, so as to enable the cover to be separated from the body, said weakened portion being formed in the body at a point which is located between the bottom of the cover and the upper edge of the closed container, and a member located at least in part between the cover flange and the adjacent wall of said body and having a tongue projecting through a slot at said weakened portion for being grasped to apply a lifting force thereby to break the part of the body above the weakened portion from the remainder of the body.

2. A container comprising a container body and a cover adapted to be tted into the open end of` said container body, a flange on said cover, said flange extending from said cover to the outer open end of said body, said body having a row of perforations therein located at approximately the middle of the height of said flange, a strip located between said flange and said body, and a tongue secured to said strip, said tongue projecting through said row of perforations.

3. A container according to claim 2, including a disc located under said cover and a tongue secured to said disc said tongue passing through the Wall of said container at the portion thereof provided With the perforations.
