,useful Improvements in Can-Closures, of

which the following is a specification.

The object of this invention is to provide improved means for sealing and closing cans, suchas oil cans, and for conveniently opening and pouring from them When'de-` sired. I

In carrying out my invention I provide means for sealing the cans airtight, a cover or ca for closing the seal and an air t'ube for admitting air to the can when pouring. The air tube and pouring opening of the can are normally sealed, but the seal may be broken to admit air lto the interior o. the can and provide a pouring orifice.

In the accompan ing drawings I have shown several modi ed forms of my invention.

Figure 1 is a view partly in elevation and partly in section illustrating an oil canwitli my invention applied. Fig. 2 is a detail plan view of a portion of the can showin the pouring orifice with the cap remove but with the seal unbroken. Fig. 3 is a sectional detail view of a part of the oil can shown in Fig. 1 with the cap lifted. Fig. 4: is a detail sectional view where the can has no spout .or 'cap but Where cutting and punching orifices are indicated. Fig. 5 is a detail sectional View of another modification in which a portion of the can is depressed at the pouring part, a cutting part is indicated and the air tube is sealed by a plug. Fig. 6 is a plan view of the modification shown in Fig. 5.

Referring first to Figs. 1, 2 and 3, A indicates a can of ordinary construction, it is provided with a threaded nozzle a which receives a screw cap B preferably carrying a cork disk C. The outer end of the nozzle is sealed by metal at D. This metal is of such nature that it may be readily cut. The outer face of the sealing metal D is preferably scored at d and marked with the word out, This sealing metal is also scored at el and marked punch l/Vithin the can is an air tube E which opens into the can at g and its outer end c is arranged close to the punching portion el of the seal D. When the can is filled it is tightly sealed at D and the cap B is applied.

In this form the can is put on the market. The user can readily remove the cap B and then with a suitable tool cut the seal D at d and punch it at d. The contents of the can may then be easily poured. After the desired amount of material is poured from the can the nozzle may be closed by the ca B provided with the'cork C. This affor s a sufficient sealing means for the can until its contents is exhausted.

In Fig. 4 the nozzle is dispensed with and a depression is formed at G in the can which is preferably scored at g to indicate where the can should be cut for ouring and it is also scored at g and maiilred punch to allow the air to enter the Ventilating tube E.

In Fig. 5 a depression is formed in the can at H which depression is scored at z, to indicate ,where the can is to be cut and the air tube E extends into the flange l1. of the depression. The plug I serves to seal the opening of the tube E. When the plug is removed air can freely enter through the tube and the can may be cut at 7i. The plug is relied onto seal the openings when the can is in use.

Fig. 6 is a plan view of the can shown in Fig. 5 with the plug removed.

The can may be filled before scaling in various ways. There may be an opening made anywhere in the can for filling purposes which may be ti litly sealed, the pouring opening hereinbe ore referred to being sealed in the manner before described, or the can may be filled through the pouring opening and then this opening may be closed in various ways. Referring to Figs. 1, 2, 3, for instance, the spout may be formed integrally with the seal D and this spout may be soldered at its lower or inner end to the can around the pourinfr opening, the seal D being formed integraltly with the sides of the spout and the tube `E is soldered to the y be filled through a specially provided opening which is properly sealed when the can is filled, or the part H may be made separately and soldered on to the top of the can. In

each instance it will be observed that the top of the can has a portion ofi-set to form a' pouring opening and said off-set portion is provided With a permanently attached seal.

I claim as my invention:

1. A can provided with a top having a portion ol'set t0 form a pouring opening which is provided With a permanently attaohed seal, an air tube opening into the can extending into the pouring opening and being in contact with and closed by the me tallic seal.

2.r A can provided With a top having a pouring opening provided with a perma nently attached metallic seal, an air tube opening into the can and having itsv outer end in Contact With and closed by said metallic seal.

In' testimony whereof, I have hereunto subscribed my name..

WILLIAM USTICH HARRIS.
