CHAPMAN D. HENRIQUES, 9F WONT, NEW YOIEIK CAN-CLOSURE CONSTRUCTION.

Applicatlonnled December 21, 921. Serial in. 523,949.

To all whom it may concern:

Be it known that I, CHAPMAN D. HEN- .mouns a citizen of the United States, and

a resident of Larchmont, in the countyof Westchester and State of New York, have invented a new and improved Can-Closure Construction, of which the following is a full, clear, and exact description.

' one manne This invention relates to a closure construction for cans and receptacles. An obgect'of the invention resides in the provision of a simple, strong, efiective but economically manufactured closure construction. Another object resides in the provision of means whereby after the can has been originally filled, a sealing device is placed on the can hich can be operated in only me permit the contents of the can to be poured out, and which sealing means cannot .be used again.

A further object resides in the particular construction and arrangement. of parts:

whereby after the seal has been broken the closure plug used will when inserted in place form a very tight and elfective seal to prevent the spilling of the liquid within the can.

A still further object resides in the par ticular construction of the spout with relation to the neck of the can or closure whereby as the liquid is being pouredout of the can none of it cancollect around the neck after the pouring has ceased.

Another object resides in the particular construction and arrangement of arts which are hereinafter described and claimed and shown in the accompanying-drawings.

The invention is illustrated in the drawin of whichigure 1 is a partial vertical section of the can and construction of'closure.

Fig. 2 is a sectional view of the essential elements of the plug portion of the closure.- I Fig. 3 is a sectional view of the parts-of the neck and spout, including the sealing diaphragm.

The form of the invention shown in the drawings is a preferred form, although it is understood that modifications in the construction and arrangementof theparts and in the character of the materials used may be adopted without departing from. the spirit of-the invention.

f This invention is applicable to a recep- .tacle'suchasacanhavingsidewallsland 'reversel 15. This diaphragm is to be disposed iii a cover portion 2. This cover portion is provided with the usual handle 3 and an aperture 4 in which the closure construction is disposed.

The closure comprises an interiorly threaded neck-piece or shell 5 (see Fig. 3). Adjacent the upper end of this shell or neckpiece 5 a horizontal flange 6 is formed on the inner edge of which there is an upstandingrib7. A pouringspout 8 provided with an aperture 9 fits around the rib-7 and rests on the flange 6. When the spout is so disposed, the rib 7 is crimped over, as shown in- Fig. 1, to hold the spout on the. neck,

although the crimping is not tightenough to prevent the rotation of the pouring spout around the axis of the neck.

The spout 8 adjacent the aperture 9 is provided with rather steep walls 10 which 75 flare down close to the upper end of the neck 5. The floor surface 11 of the pouring spout, as can 'be seen from the .above description, and especially the view in Fig. 1,

is practically flush with the upper edge of so the neck so that in pouring the liquid meets no obstruction from any part of the neck portion since the. path of the liquid from the neck through the spout is uninterrupted.

The surface 12 of the cover 2 to which the closure portion is attached is depressed so that when the spout 8 is moved around to permit the end or floor 11 to extend beyond the can for the purpose of pouring the liquid therefrom, when the can is again disposed,

after pouring, in normal position the liquid will tend to run. back to the rear of the spout 8 and will, therefore, immediately run back into the can because the bottom surface of the spout is flush with the top of the neck 5 and, therefore, there is no possibility of any liquid being trapped. When it is not desired to pour the liquid, the spout is turned around in the full line position shown in Fig. 1 so that the end 11 is out of the way.

I wish also to provide an efi'ective,.simple and economically manufactured sealing means normally to be disposed in the aperture'4= until the consumer of the liquid de- 1 sires to use it. This sealing means comprises'a cup-shaped diaphragm 13. having a horizontally extending flange 14 and a curved, vertically tapered flan the neck 5, as shown in Fig. 1, the flange 14 resting on a flat surface 16 m the bottom of the neck 5 by depressing the middle thereof. The side walls 17 of the diaphragm 13 lie parallel to a vertically depending flange 18 on the bottom of the neck 5. This relation is clearly seen in Fig. 1. The flange 14 and the surface 16 can be firm 1y connected together, if desired, by any suitable process, such as welding or soldering, or they may even be left unconnected except as they are held in position by the plug or cork device to be hereinafter described.

The tapered flange 15 provides a tapered aperture in which a removable seal is disposed. This removable sealcomprises a cupshaped seal of sheet metal, such as 19, with a horizontally extending flange 20. The cup portion of this seal 19 is similarly tapered and adapted .to be disposed within the aperture formed by the flange 15. As shown in Fig. 1, this effectively seals the connection between the inner portion of the can and the atmosphere. The-seal 19 fits tightly in the aperture formed by the flange 15 and can be removed therefrom only by considerable pressure and only by pushing it into the can. It cannot be removed by pulling it out of the opening formed by the flange 15. In this way, a person wishing to get at the liquid within the can can do so; but after this seal has once been broken, it is impossible to use a similar seal without taking the closure construction completely off the can.

The plug or cork member comprises essentially a threaded hollow shell 21 having a removable cap 22 over which the upper edges of the shell 21 are spun. In the bottom surface 23 of this shell, I provide a cuplike depression 24 formed by depressing the metal of the bottom wall 23. Into this depression 24 the body portion 25 of a cuplike clamping member.is to be disposed. The clamping member 25 has an outwardly extending annular flange 26 thereon. .When the clamping member 25 is forced into the recess 24 an annularly shaped washer or packing ring 27 is gripped between the flange 26 and the bottom surface 23 of the shell 21, as shown in Fig. 1.

When this arrangement of the parts has been effected, the inner abutting walls of the recess 24 and the member 25 are crimped over, as shown in Fig. 1, to hold the clamping member 25 in position to efi'ectively grip the washer 27. The outer edges of the washer are especially adapted to bear on the flush surface formed by the flange 14: on the adjacent flat surface of the shell 5, so that a very tight joint is here formed to prevent the leak age of fluid from the container after the seal has been broken and the plug is being used.

It will, therefore, be seen that I have 'provided a simple, efficient, strong, easily manufactured closure construction whereby the ob-' jectionable dripping of'liquids around the spout of such receptacles is eliminated; whereby an eflective joint can be made between the plug or cork and the bottom of the neck after the seal has been broken, or even before, to prevent leakage of the contents of the can.

What I claim is:

' A closure construction for cans, which comprises a neck exteriorly threaded and extending above the upper surface of the can, an annular outwardly extending flange near the upper end of the neck, a vertically extending ring adjacent the flange, and a spout having an aperture therein to surround'the ring and rest on the flange, the ring adapted to be crimped over to engage the spout, the spout being rotatable around the upper edge of the neck, the floor of the spout being disposed substantially flush with the upper edge of the neck, the spout in one position extending outwardly away from the can, and in the opposite position being disposed within
