INVENTOR W/LL/A M J. SLADE ATTORNEYS United States Patent '0 DETERGENT CAN William J. Slade, Haddonfield, N. J., assignor to Crown Cork & Seal Company, Inc., Philadelphia, Pa., a corporation of New York Application July 27, 1955, Serial No. 524,787

2 Claims. (Cl. 222'562) This invention relates to containers such as metal cans useful particularly for detergent liquids and powders.

The container has its ends normally closed and one of 4 the ends is formed with means for securely receiving a plastic pouring spout. The latter, in turn, may be threaded or otherwise provided with a cap-receiving finish to thereby receive and retain a reseal closure. Thus, the can may be effectively sealed at all times, both prior to initial opening and thereafter until the contents are used up.

Referring to the drawings:

Figure 1 is a top view, and

Figure 2 is a section on line 22 of Figure l with the container body broken away.

In the drawing, 10 indicates a conventional cylindrical metal container body having, at its top and bottom, customary metal ends 11 seamed to the body in the usual manner, as shown at 12.

The top end 11 is dome-shaped, i. e., centrally convex, as shown at 13, and the dome terminates upwardly in a continuous closed fiat portion 14 having an inwardly extending shoulder 15. The flat portion 14 may be scored to aid forming the opening 0.

In use, after this flat portion 14 has been severed to form an opening of any desired size, a neck-pouring spout 16 with cap 17 is attached to the end 11 to continue the seal, as the contents are used up.

This neck-pouring spout is made of plastic such as polyethylene, and has an integral, circular base or flange 18 of greater diameter than the upstanding, cylindrical neck 16, as shown. The undersurface of the flange 18 is flat, as shown at 19, to correspond with and engage the flat surface of the portion 14 of the end. The circular skirt 20 of the flange has its inner wall 21 undercut to form an inwardly extending groove 22. This circular groove 22 will receive, in resilient, frictional, sealing fit, the' circular pouring spout-receiving shoulder 15,

as shown.

The neck-pouring spout 16 is shown as having a threaded cap-receiving finish 23 to receive a usual threaded reseal cap 17 of plastic, such as polyethylene, or metal, as desired. The cap is provided with the usual sealing liner 25 on its inside engaging the integral, outwardly extending, rounded bead 26 of the pouring spout. The neck above the threaded area is inclined inwardly at 27 and extends upwardly as the cylindrical portion of reduced diameter 28 terminating in the outwardly projecting, rounded head 26. The top of the plastic closure 17 has diametrically intersecting grooves 29 for receiving a tool to turn the cap to open or closed position for convenience, and, if desired, the flange 18 is suitably knurled or provided with spaced hand-gripping projections 3i? to assist in applying the pouring spout to the container and locking the same thereto, as abovedescribed.

2,844,290 Patented July 22, 1953 The container may be provided initially with the opening 0 and the pouring spout 16 and cap 17 in position as shown. Also, the top 14 may be scored so that the opening may be easily formed. The container may be made of plastic, such as polyethylene, and, as stated, the pouring spout and closure may be of metal or plastic.

While I have mentioned polyethylene as the preferred plastic, other suitable plastics may be used.

While the threaded finish 23 is preferred, other conventional closure-receiving finishes may be used, e. g., to receive lug caps, crowns and pressed-on caps, the closure 17 being shown with cap-receiving threads 24 to engage the threaded finish 23 for purposes of illustration.

The container structure above-described provides a continuous and reliable pouring spout and reseal for liquids, pastes and granular products which are customarily packed in metal or plastic containers.

It will be observed that the container 10 has the end 11 provided with the projection defined by the flat surface 14 and the integral shoulder 15, the latter extending inwardly and downwardly therefrom, and that the pouring spout has a neck portion 16 provided with an internal opening 0' which is enlarged adjacent the flange 18, and is of reduced diameter as it passes centrally through the neck or pouring spout 16. The flange portion, as stated, has the flat portion 21 engaging the flat surface 14 of the projection, and this flange also has the depending skirt 20 formed with an internal groove 22 for receiving in frictional, resilient, sealing relation the shoulder 15 of the projection on the end 11. Whether the flat surface 14 is provided initially closed or closed and provided with a scoring defining an opening 0, or the opening 0 is already formed in the surface 14, the respective openings 0 and O communicate when the pouring spout is in position, as shown. As will be appreciated, the container can be supplied independently of the pouring spout, i. 'e., the spout may be attached to the container, either before or after an opening 0 is formed in the flat surface 14. That is, the pouring spout is detachably secured to the end 11 and, of course, where the opening 0 is initially formed in the surface 14, the pouring spout and its closure will form a part of the container package before or after the same has been filled.

Referring to Figure 2, it will be observed that not only does the shoulder 15 engage in the groove 22, but the flange being located at the base of the pouring spout, has the lower edge of its skirt 18 also engaging the adjacent curved top surface of the end, as shown at 31, to further assure, not only a rigid fit, but a tight seal as well.

It will be appreciated that the preferable construction consists of a metal container having a metal end with a plastic pouring spout, as illustrated.

I claim:

1. A cylindrical container having a metal end, a projection on said end having a flat surface and an integral shoulder extending inwardly and downwardly therefrom, a plastic pouring spout having a cylindrical neck portion provided with an opening and a flange portion located at the base of the pouring spout, said flange having a flat surface engaging the flat surface of the projection, a depending skirt on said pouring spout flange formed with an internal groove for receiving in frictional, resilient, sealing relation the said shoulder of the projection, the lower edge of said skirt of the flange also engaging the container opening through its flat surface in said end into the opening of the pouring spout, the pouring spout terminating in an upper, cylindrical, rounded bead portion of lesser diameter than said neck portion, and the outer wall of said pouring spout being adapted to receive a closure.

2. A container according to claim 1 having a closure thereon, said closure being in sealing relation with the roundedbead portion of said pouring spout.
