CLOSING DEVICE FOR TINS Filed April 1, 1932 Jbren/ar 5 FAJFeic/mz J/farney Patented Mar. 6, 1934 UNIT STATES assignor to firm Verkaufsstelle des Internationalen Susstofi-Syndikats Gescllschaft mit beschrankter Haftung, Hamburg, Germany Application April 1, 1932, Serial No. 602,549 In Germany April 2, 1931 2 Claims.
This invention relates to a closing device for tins which are used for packing sundry materials, such as cocoa, sugar, meal, or any chemical substances. The invention is applicable to all forms 3 of tins which may be of circular, rectangular, or
any other suitable cross-section.
One object of the invention is to provide a closing device, which nearly hermetically closes the tin, and which is free from objection from the hygienic point of view, at the same time being constructed in such a manner as to allow an easy and quick opening movement and an entire removal of the disk without leaving portions of the closing disk with sharp edges liable to hurt or i injure the fingers.
Another likewise important object of the invention is to provide closing means whichhaving been opened once-do not allow of a replacement thus making-believe that the tin was not opened or the contents not touched. With these objects in view the invention consists of the features below referred to with reference to the drawing.
In the accompanying drawing Fig. 1 shows partly in a central vertical section, partly as an elevation one form of a tin with the closing device in accordance with the invention with a removable cover represented in a somewhat removed position;
Fig. 2 is a plan view of the tin of Fig. 1 looking upon the closing device with the removable cover entirely removed;
Fig. 3 is a sectional view through the upper part of the tin of Fig. 1 in a larger scale;
Fig. 4 shows, partly in section, a second form of construction of a tin having a hinged-on cover;
Fig. 5 being a plan view upon the closing device of the tin of Fig. 4 with the hinged-on cover opened.
The tin represented in Figures 1 to 3 comprises a cylindrical body 1 of sheet metal, a bottom 2 of the same material and a removable cover 3 preferably likewise of the same material. The bottom 2 may be integral with the body 1. It may, however, consist of a separate sheet connected to the cylindrical body in any suitable manner e. g. by rolling. The cover 3 is adapted to be applied to the top of the tin in the usual manner with a tight fit on said top. It may be removed entirely from the tin not being connected to it in any way.
At the top the cylindrical body 1 of the tin is closed by a closing disk 4. This disk is connected to the upper edge of the body 1 in a peculiar manner which can be under tood b t by referri to Fig. 3.
(Cl. EMF-5 Near the top the wall of the body 1 is shaped in such a manner as to form an annular recess 5. This recess is formed or surrounded by a lower wall portion 6 bent inwardly from the outer wall of the body 1, by an intermediary or connecting web 7 and by an upper fiangelike wall portion 8 bent outwardly from the web '7. In practice the portions 6 and 8 are situated in planes substantially perpendicular to the vertical axis of the tin and are so close to each other that the web piece 7 is of minimum height. The upper wall portion 8 forms an annular flange at the top of the cylindrical body of the tin.
The closing disk 4 is destined to close the tin at the top as tightly as possible. For this purpose it is provided on its edge with an annular flange 9 turned inwardly on the total circumference of the disk. Flange 9 grips with a tight fit into the annular recess 5 formed at the top of the tin body. The portions or flanges 6, 9 and 8 respectively are lying close one upon the other when the closing disk is applied to the tin so that the contents of the tin are nearly hermetically sealed also at the top.
The closing disk 4 is provided with an opening strip 10 which is formed by two parallel incision lines 11 and 12. On one end of that strip a tongue 13 is arranged. The strip preferably runs along a diameter of the circular disk 4. It may be torn by inserting the tongue 13 into the slot of a usual key and by being rolled about that key in a manner well known. The incision lines 11 and 12 respectively may be made as deep as is necessary for an easy separation of the strip 10 from the remaining material of disk 4.
In known closing devices for tins when a closing means such as disk 4 is employed, said disk being connected to the top of the tin body in any known manner, it was necessary to employ a special tool for opening the tin by opening and removing said closing disk. No special tool is required for opening a tin or its closing disk 4 respectively constructed in accordance to the invention, but a simple and well known key having a slot for reception of the tongue of an opening strip, such as tongue 13 of strip 10, may be used.
Further in known devices the closing disk usually cannot be removed entirely from the top of the tin, portions of the disk still being left ing strip 10 it is easy to completely remove the remaining portions of the disk 4 these portions mainly consisting of two halves separated from one another.
It is the peculiar manner of connecting the disk 4 with the top edge of the body 1 which makes the easy and complete removal of the disk possible without the danger of sharp edges remaining in the opening.
Another advantage inherent to the invention likewise is rather important. With known closing devices it is possible to entirely remove the closing disk or the like, to empty the tin, to refill it with another substance and to replace a closing disk resembling the original one. With the device of the invention such deceptive manoeuvres are impossible. The reason for this is again the peculiar connection between the edges of the closing disk i and the cylindrical body respectively which renders it impossible after having opened the closing device to replace the pieces of the closing disk or a new closing disk in a manner to make-believe that the tin is unopened. The construction of the top edge of the cylindrical body 1 further is such that the fingers may not be injured or hurt by it.
The modified form of tin shown in Figures 4 and 5 resembles the modification of Figures 1 and 2 in all important parts, the section of Fig. 3 being applicable to the modification of Figures 4 and 5. In these figures the tin is of rectangular cross-section. The strip 10' being diagonally arranged on disk 4. Another difference is this that the cover 3 is hinged as at 14 to the upper portion of the body 1'. Otherwise the construction being the same the same advantages and improvements are obtained as by the modification of Figures 1 and 2.
I claim:
1. A closing device for a tin, said tin comprising a body, a bottom and a cover, a disc closing said body at the top and connected to the top edge of said body, an opening strip extending entirely across said disc and having a tongue thereon, the extent of said strip across said disc and the connection between said disc and said body being such as to permit the entire removal of the said disc in two portions of substantially equal size, after removal of the opening strip from the disc, said body being provided at its upper edge with aninwardly, upwardly, and then outwardly extending flange, and the said disc having at its periphery a downwardly and in- Wardly turned flange, pressed between the inwardly and outwardly extending portions of the flange on said body.
2. A closing device for a tin, said tin compris ing a body, a bottom and a cover, a disc closing said body at the top and connected to the top edge of said body, an opening strip in said disc and having a tongue thereon, the top edge of said body being shaped to provide an annular recess, an inwardly turned annular flange on the edge of said disc cooperating with and adapted to be inserted into said recess, said opening strip extending completely across the largest diameter of said disc, so that when the opening strip is removed, the said disc can be entirely removed in two portions of substantially the same size and shape.
