ALFFED I. CONE, OF NEW YORK, N. Y., ASSIGNOR TO MERCK & 00., IN 0., OF RAHWAY, NEW JERSEY, A CORPORATION OF NEW JERSEY.
Application filed November 16, 1927. Serial No. 283,638.
This invention relates .to dispensing receptacles of that type commonly known as powder cans or boxes, and has more particular reference to an improved form of closure for such receptacles, whether in part of glass, metal or card board, including an improved form and mounting of a rotary cutoff element.
The present invention has particular reference to the provision of an improved closure for the top of cylindrical cartons or cans, in
which a rotary cut-off element is provided, and an important object of the invention is to provide a construction which is extremely simple and durable, eflicient and reliable in operation, and capable of convenient assemblage.
The invention essentially includes a can or carton having a cylindrical body or a'cylindrical upper end portion, a slip cover fitted on the upper end of the body and having an opening therein, and a rotatable disk resting at its margin on the upper edge of the carton body and confined thereon and beneath the apertured top wall of the cover by the latter, said rotatable disk having an opening which is adapted to be brought into and out of registry with the opening in the cover by suitably rotating the disk.
Other objects, advantages and structural features will become apparent as the nature of the invention is better understood, and the same consists in the novel form, combination and arrangement of parts hereinafter more full described, shown in the accompanying rawing and claims.
In the drawing, wherein like reference characters indicate corresponding parts throughout the several views,
Figure 1 is a top plan view of a can or carton provided with a closure constructed inaccordance with the present invention;
Figure 2 is an elevational view thereof;
Fi re 3 is a vertical section on line 33 of Figure 1, partly broken away;
Figure 4 is a vertical section on line 44 of Figure 1, partly broken away;
Figure 5 is a top plan view of the rotatable disk or cut-off element; and
Figure 6 is an edge elevational view of the device shown in Figure 5.
Referring more in detail to the drawing, 5
1 indicates the cylindrical body of a can or carton whose lower end may be closed by means of a suitable slip-on closure cap 6 whose marginal flange 7 may be suitably permanently fastened to the body 5 after the latter has been filled through the bottom with the powder or other material to be contained in and dispensed from the can.
The upper end of the body 5 is provided with a slip cover or closure cap 8 having a marginal rim or'fiange 9 adapted to snugly and frictionally fit over the upper end of the body 5 so that the cover is efiectively retained in place on the body, and formed in the top wall of the cover 8 is an arcuate or segmentshaped dispensing opening 10.
Disposed against the under side of the top Wall of the cover 8 and confined by the latter upon the upper edge of the body 5 is a' rotatable closure disk 11 formed with an arcuate or segment-shaped opening 12 adapted to be brought into and out of registry with the opening 10 by suitably rotating said disk 11. It will of course be understood that the disk 11 is of sufiicient diameter to rest at its margin upon the upper edge of the body 5 and to be effectively confined in place by means of the cover 8 so that no pivotal connection between the disk 11 and cover 8 is necessary or desired. By reason of this arrangement, a simple construction is had which may be conveniently and readily assembled. It will further be apparent that by turning the disk 11 the opening 10 may be opened to any desired degree in accordance with the quantity of material desired to be dispensed and the character of the material.
The disk 11 is preferably stamped from a flat sheet of metal so that in stamping the material therefrom to form the opening 12, a tongue 13 is left at one end of the opening 12 and attached at one end to the outer wall of said opening 10 as shown. 'This tongue 13 is directed upwardly to pass upwardly through the opening 10 in the cover 8 and is then directed laterally and outwardly beyond the edge of the cover 8 for convenient use as a finger piece or handle whereby the manual rotation of the closure disk 11 is facilitated or efi'ected. In order to enable the openings 10 and 12 to be made of the same size, and yet permit full closing of the or tongue 13 may move when the disk 11 is brought to closing position as shown in Figure 1.
A thin frangible membrane of smooth paper or the like is provided, as at 15 beneath the disk, and which will be exposed when the opening 12 of the disk is brought in registry with the opening 10 in the rotatable closure disk 11. This will prevent seepage of the powdered material out of the container during shipment and will discourage tampering with the contents of the receptacle or can at such time. In the preferred construction, the membrane 15 consists of a sheet of thin paper having its margin turned down about the upper end of the body 5 and securely held between the latter and the rim 9 of the cover 8 so that the membrane is tightly stretched and maintained across the upper end of the body against the underside of the closure disk 11. The downturned margin of the membrane 15 is clearly shown as 16 in Figures 3 and 4. By reason of the smooth surface of the membrane 15 interposed between the margin of the disk 11 and the upper edge of the body 5, the ease of rotation of the disk 11 is promoted.
In assembling the present closure, the disk 11 is operatively disposed within the cover 8 and the sealing membrane 15 is applied to the upper end of the body with its (margin 16 downturned. The cover 8 with the disk-11 assembled therein is then forced onto the upper end of the body 5 so that the margin of the membrane 15 is firmly held, whereupon the device is ready for use.
When the contents of the can or carton are to be'used, the disk,11 is turned from the full line position of Figure 1 so that the dotted line position of the'opening 12 thereof may be brought into registry with opening 10 to the desired degree, whereupon the membrane 15 will then be exposed and may be suitably ruptured or punctured by the finger or some implement passed through the said registered opening.
From the foregoing description it is believed that the construction and operation as well as the advantages of the present invention will be readily understood and appreciated by those skilled in the art.
Minor changes may be made without departing from the spirit and scope of the invention as claimed.
What I claim as new is y 1. In combination, a receptacle body having a cylindrical upper end portion, a manaially rotatable closure disk resting at its margin'on the upper edge of said upper end portion of the receptacle body, a flanged cover fitted on the upper end portion of said body over said closure disk and formed with a dispensing opening, said disk having an opening adapted to be brought into and out of registry with the o ening of the cover when said disk is rotate, and a tongue integral with the outer wall of the closure disk opening at one end of the latter and-projecting upwardly through the opening of the cover to form a handle for rotating said disk, said cover having a slot extending circumferentially thereof from one end of its opening to receive said tongue when the disk is rotated to closing position.
2. In combination, a receptacle body having a cylindrical upper end portion, a manually rotatable closure disk resting at its margin on the upper edge of said upper end portion of the receptacle body, a flanged cover fitted on the upper end portion of said body over said closure disk and formed with a dispensing opening, said'disk having an opening adapted to be brought into and out of registry with the opening of the cover when said disk is rotated, and a tongue integral with the outer wall of the closure disk opening at one end of the latter and projecting upwardly through the opening of the cover to form a handle for rotating said disk, said coverhaving a slot extending circumferentially thereof from one end of its opening to receive said tongue when the disk is rotated to closing position; and a smooth-surfaced frangible membrane stretched over and closing the upper end portion of the body beneath the closure disk.
