CAN-NOZZLE.

Specification of Letters Patent.

Application filed May 12, 1911.

Patented Feb. 13, 1912.

Serial No. 626,870.

To all whom it may concern:

Be it known that we, EDWIN NoRTON and BERNARD H. LARKIN, citizens of the United States, residing in Paget, Bermuda, and Chicago, county of Cook, State of Illinois, respectively, have invented certain new and useful Improvements in Can-Nozzles, of which the following is a description, reference being had to the accompanying drawing and to the letters and figures of reference marked thereon.

Our invention relates to an improvement in cans or other receptacles, and especially to closures therefor; the object being to provide a can having an outlet which may be closed to keep out dust when the can is shipped from the manufacturer to the packer, and which has an additional closing element made separate therefrom, which may be applied by the packer to the outlet after the can has been filled to hermetically seal the same, the cover of said additional closing element being formed of material to be cut away, to allow, access to the contents of the receptacle, the cover of the first closing element thereafter serving as the closure.

Our invention is illustrated in the accompanying drawings, in which Figure 1 is a perspective View showing a can body having a nqzzle with the improvements applied thereto, the inner closure being omitted. Fig. 2 is a sectional view of our nozzle complete; Fig. 3 is a similar view, showing the same after the sealing member has been removed; Fig. 4 is a detail sectional view of the metallic sealing member; Fig. 5 is a modification of Fig. 4; and Fig. 6 is a sectional view showing the closure applied directly to the open end of a can.

In carrying out the invention, the same ma be applied to the open end of a can body or to a can nozzle attached to and projecting from a can body.

In the drawings, 1 represents an ordinary can such as used for varnish, paints, or other substances, and this can is provided at the top with a nozzle 2, which is specially constructed at its outer end to receive the improved closing means forming the essential features of the invention. This nozzle as a whole is constructed as follows: It has a lid 3 stamped out of sheet metal and formed with a hinge member pivotally engaging the rim of the nozzle, and has a spring tongue 4, engaging the projecting edge of the nozzle. Said lid has on its under side a recess formed by crimping around the edge of the lid, and convexing the portion inside the rim, this recess forming a seat for a gasket or packing ring 5, adapted when the lid is closed to press on the edge of the nozzle all the way around. The nozzle 2 has an inner shoulder 6 all around the inner periphery.

Fig. 1 represents the can as it is shipped from the factory to the packer, the lid being closed to keep out the dust. To hermetically seal the package, however, after filling, it is necessary to provide an additional closing element which is shown in Figs. 2, 3 and 4 at 7 and in Fig. 5 at 7 This element 7. as shown in detail in Fig. 4 is formed of sheet metal wi th the downwardly projecting wall 8 frictionally engaging the inner wall of the nozzle 2, and having a flange 9 resting on the shoulder 6. After the receptacle has been filled, the sealing element 7 is forced into position, which effectually seals the contents and then the lid is closed.

When the consumer desires to open the can for use, he cuts away the top of the element 7, and thereafter the use of the hinged top keeps the contents free of dust and dirt.

As shown in Fig. 5, the element 7' has a paper or fabric top held in osition by crimping the upper wall of t e flange 9 around it. We prefer, however, to use tin for this closure or sealing member. It will be understood that the packing ring or gasket 5 may be placed on the nozzle instead of on the cover.

In Fig. 6, the invention is shown as applied directly to a can body 10 which is formed with an open upper end. The upger edges of the can body are bent outwar ly and thence upward, to form a seatin shoulder 6. The edge beyond the seating s oulder is formed into a shelf in a manner similar to forming the shelf above described. The lid or cover 3 is provided with a packing ring or gasket 5, and said lid is hinged at one side to the outer edge of the can body, while at its other side a retaining clip or tongue 4 is provided for holding the lid closed. The closing element 7 is seated within the open end of the can body and the downwardly projecting wall 8 frictionally engages the walls of the can body to hold the closure in the can body. These closures 7 are shipped separately and may be inserted after the can is filled. Access is gained to the contents of the can in the same manner as above described.

Having thus particularly described our invention, what we claim as new and desire to secure by Letters Patent is:

A metal receptacle including in combination, a body portion having an opening, the metal adjacent said opening being bent to form a seating shoulder, and an outwardly projecting flange, an inner closure having a downwardly projecting wall for frictionally engaging the body portion of the receptacle, said inner closure having a projectin ledge adapted to rest on said seatin shoul er, a cover hinged at one side to sai flange and adapted to seat thereon, means for holding the cover closed, means for securing a gasket to said cover, whereby said gasket seats against the flange on the body portion when said cover is closed.

In testimony whereof we afiix our signatures, in presence of two witnesses.
