Jan. 29, 1952 P. SANTINA CONTAINER FOR ASPHALT AND THE LIKE Filed March 24, 1949 INVENTOR. afer Sanf/na WWW Patented Jan. 29, 1952 UNITED STATES PATENT OFFICE 2,583,669 CONTAINER FOR. ASPHALT AND THELIKE Peter Santlna, San Francisco, Calif.

Application March 24, 1949, Serial No. 83,232 5Claims. (01. 220-49) This invention relates to a metal container for asphalt and the like. More particularly, it re lates to a metallic container or barrel formed with the usual sideseam and having. means for ripping open the sideseam so as to allow access to the contents of the container.

In packaging asphalt it is common practice to provide a cylindrical metallic container or barrel having a bottom closure and open at the top. The asphalt exists in the container in the form of a cylindrical block, and at the point of use it is essential either to heat the container to melt the asphalt so that it may. flow from the container, to chop out the solid contents of the container, or to rip open the container to provide access to the solid block of asphalt.

The various means previously employed for removing asphalt from such containers have been unsatisfactory. Heating is obviously undesirable, especially at small installations. Thus, a source of heat must be provided, and also means for handling the hot containers and the hot fiuid asphalt. Time must be allowed to melt the asphalt.

Chopping the asphalt out of a container is obviously laborious, and prior methods of ripping the container have also been laborious and have damaged the container excessively.

It is an object of the present invention to provide improved means for opening metallic containers of the character described.

It is a particular object ofthe invention to provide a means for opening metallic containers containing asphalt, such means being embodied in the container and immediately available whenever desired to open the container.

It is a further and particular object of the in vention to provide a simple and eiiective means for opening a metallic container containing asphalt or the like, such means being effective to part the container at its sideseam while at the same time doing a minimum of damage to the container. I

These and other objects of the invention will be apparent from the ensuing description and the appended claims.

Certain forms which the invention may assume are exemplified in the following description and illustrated by way of example in the accompanying drawings, in which:

Fig. 1 is a perspective view of one embodiment of the invention.

Fig. 2 is a section taken along the line 2-2 of Fig. 1.

Fig. 3 is a section taken along the line 3-3 of Fig. '1.

Fig. 4 is a perspective view of another embodiment of the invention.

Fig. 5 is a section taken along the line 5-5 Fig. 4.

Referring now to the drawings, and more particularly to Figs. 1, 2 and 3, there is shown a cylindrical metallic container or barrel I0 having a body ll preferably constructed of a light gauge metal such as a light gauge aluminum al- 10y. The body is provided with a bottom closure I2; The container is shown as being filled with a solid material It, such as asphalt. The usual sideseam I l and double end seam 15 are provided. Referring more particularly to Figs. 2 and 3, as illustrated, the sideseams i l comprise an inner hook l6 and an outer hook I! which is interlocked with the inner hook. The double end seam comprises an inner hook it and an outer hook l9 which is interlocked with the inner'hoo'k.

The container Ill embodies a wire rip cord 25 which, as illustrated, is seated in the bend of the cuterhook ll of the sideseam It. At its ends the wire rip cord 25 is formed into a loop 26 or 21. A5 shown in Fig. 3 the rip cord is also seated in the double end seam l5 and it has the same general configuration as the outer hook it. The wire 25 is preferably a piano wire or other wire having a comparable high tensile strength.

In manufacturing the container It the usual procedure is involved. That is, the body blanks are formed and notched and hooks are formed for forming the sideseam and a flange is formed for forming the end seam. The ends are also formed with flanges for the end seam. The only respect in which usual can forming operations are modified is that the rip cord 25 is inserted in the outer hook l! before the latter is interlocked with the inner hook I6.

When it is desired to remove the asphalt [3 from the container, the upper loop 26 of the rip cord '25 is grasped by hand or with a tool such as a pair of pliers and is pulled laterally and downwardly as indicated by the arrow a in Fig. l. The wire thereby cuts the outer hook I! at its bend or crease which, of course, is the weakest point in the seam. The sideseam M is thus effectively ripped. To remove the bottom closure l2, the bottom loop 21 will be pulled upwardly to interlock the double seam l5. It is then a. simple operation to peel the body H and the bottom closure I2 from the solid block of asphalt l3.

Referring now to Figs. 4 and 5, the container l there shown is identical with that illustrated in Fig. 1 and described hereinabove except that it is provided with a lid 28 which may be secured to the body II by means of a double seam 29 or by any other suitable means. As also illustrated, near its top and bottom, the body II is slotted to provide annular top and

bottom grooves

30 or 3|. The rip cord 25, having end loops 26 and 21, is disposed in the sideseam l4 and projects outwardly from the end seams l5 and 29 in the manner described hereinabove and illustrated in Figs. 2 and 3.

In this embodiment of the invention the rip cord 25 may be manipulated as described above. However, it is not necessary to rip off both end closures. Thus, the rip cord 25 may be pulled downwardly until it rips the body ll between the upper and lower

annular grooves

30 and 3!. These grooves so weaken the body II that, after it has been ripped between the

grooves

30 and 3|, it is a simple matter to peel the central portion 32 of the body II from the block of asphalt. Thus, access is provided to the asphalt without ripping off the bottom closure.

This embodiment of the invention is especially adapted to containers in which the bottom closure, the top closure or both end closures are clamped to the body of the container by means such that a rip cord will not remove them. Thus, it is necessary to extend the rip cord only from the top groove 30 to the bottom groove 3|.

It will be apparent that a novel and very useful means for opening a metallic container or barrel is provided. Such means is inexpensive, involving no modification of the usual seam forming operations in forming a container except to place a small length of wire in the outer hook of the sideseams before forming the seam. Operation of the device is extremely simple, and may be carried out manually or by means of a simple tool such as a pair of pliers. A further and important advantage resides in the fact that the body H of the container is damaged only to the extent that the inner portion of the outer hook is ripped loose from the main body of the container. This constitutes a very small fraction of the container. The body ll, after cleaning, can be used again to form a container having practically the same volume.

While I have shown the preferred form of my invention, it is to be understood that various changes may be made in its construction by those skilled in the art without departing from the spirit of the invention as defined in the appended claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent isl. A metallic container having a tubular body portion including a sideseam formed, of interlocked inner and outer hooks, an end closure for said container locked to the body portion by means of an end seam, and a rip cord seated in the bendof said outer hook and also seated in said end seam, one end of said rip cord pro- 4 jecting outwardly from the container to provide a hand hold.

2. A metallic container comprising a tubular body having a side seam, a rip cord mounted within said seam and extending longitudinally thereof and beyond at least one end of the body and a cover at the end of the body from which said end of said rip cord extends, said cord being returned bent by said cover and extending between said cover and said body.

3. A metallic container comprising a tubular body having a side seam, a rip cord mounted within said seam and extending longitudinally thereof and beyond at least one end of the body and a cover at the end of the body from which said end of said rip cord extends, said cord being returned bent by said cover and extending between said cover and said body, and a pull ring formed on the extended end of said rip cord.

4. A metallic container comprising a tubular body having a side seam, a rip cord mounted within said seam and extending longitudinally thereof and beyond both ends of said body and a cover at both ends of the body the extended ends of said cord being returned bent by said covers and extending between said covers and said body.

5. In a can having a longitudinally extending side seam formed by interlocking return bent edges of the can body, a rip cord mounted within said side seam and extending beyond both ends thereof, a pair of spaced annular weakenings in the can body adjacent the ends thereof, a pair of cap-like covers engaging over the both ends of said body, the ends of said rip cord being returned bent under the edges of said covers and extending therebeyond and a pair of pull rings formed on the extended ends of said rip cord.
