Specification of Letters Patent.
Patented Sept. 4t, 191'?.
Application filed October 27, 1913. Serial No. 797,535.'
5 of Illinois, have invented a new and useful Improvement'in Triple-Seal Cans, of which .the following is a specification.
This invention relates to improvements in triple seal cans. p
An object of the invention is to provide a can or other form of container, the opening of which is closed by means of a cap and -cover between which and the top of the can body are three distinct and independent hermetic and friction seals. v
The invention furthermore consists in the improvements in the parts and devices and in the novel combination -of the parts and devices as herein shown, described or claimed.
In the drawing forming a part of this specication, Figure 1 is a vertical, diametrical sectional view of a can embodying my improvements. Fig. 2 is a top plan view of the can shown in Fig. 1, the cover being removed, and Fig. 3 is a detail sectional view illustrating a different form of a can embodying my invention.
'In said drawing, the can body is designated by the reference 10, the same being provided with a bottom 11 and top 12. The top 10 is provided with the usual central opening 13 surrounding which is an annular channel 14 formed by an up-turned inner edge 15, horizontal portion 16 and upwardly extended wall 17, the channel 14 being adapted to receive and support a gasket 18, of paper or other suitable material. Concentric with the channel 14, and outside of the same, the top is provided with two substantially vertical spaced annular friction seat walls 19 and 20, with which are adapted to coperate corresponding friction seat walls 21 and 22 formed on the cover 23,
said cover` 23 having a pryofi' rim 24 formedas shown. rIhe opening is closed by a cap 25 having a countersunk central portion 26 adapted to loosely fit within the up-turned Hange 15. Cap 25 also has an annular rib 27 and a curved peripheral flange 28, the latter being adapted to seat upon the gasket 18 to form an hermetic seal. The cover is provided with a raised central portion 29 between which and the inner friction seat wall 21 is a downwardly extended rib 30 adapted' to engage the ange 28 of the cap and press the latter firmly against the gasket.
As will be understood, the coperating friction seat walls of the top and cover are made soas to have a slight wedging fit and the friction therebetween will be suflicient not only to form two seals but also to hold the cover in place andthe cover as it is forced home will press the cap firmly into position to engage the gasket to form a third hermetic seal. On account of their formation, both the ange 28 and the portion of the can top which supports the gasket willIv be more or less yielding, thus insuring a yielding pressure on the gasket which will accommodate itself to any unevenness in the thickness of the gasket or irregularities of the cap or top.
In the form shown in Fig. 3, the top 112 is provided with two concentric, substantially vertical friction seat walls 119 and 120, a horizontal gasket supporting shelf 116 anda downwardly turned inner flange 115. The cap is provided with a countersunk portion 126 adapted to loosely fit the inner flange 115 of thetop, said cap being also provided with a horizontally extending peripheral {iange 128, between which and the shelf 116 is placed a gasket 118. The cover is provided with two friction seat walls 121 and 122 which coperate with the friction seat walls of the top. The operation of this structure is substantially the same as that described for the structures shown in Figs. 1 and 2, the cover being adapted to lirmly press the cap in place, the cover being held by the friction between the cooperating friction seat' walls. It will also be noted that the vertical walls of the countersunk portions of the caps will serve as a sort of backing for the inner edge ofthe can top, thereby preventing the latter from beingforced inwardly as the cover is forced home.
Although I have herein shown and described what I now consider the preferred embodiment of my improvement, yet it will be understood that various changes and modifications may be made without departing from the spirit of the invention, and all such changes and modifications are contemplated as come within the scope of the claims appended hereto.
I claim:
1. A container of the character described including, in combination: a body provided with a top having an opening therein, the
top having also an internalfriction seat'v *of the top, said cover being adapted t'o engage the flange of the cap to firmly press it against the gasket when the cover is forced home, said friction seal walls being smoothly cylindrical, and said cover being the outer securing means of the closure, substantially as specified.
2. A container of the character described including, in combination: a body provided with a top having an opening therein, said top having an upwardly extending inner flange, a gasket supporting shelf and a friction seat wall; a countersunk cap adapted to be loosely seated within said up-turned flange of the top and having also a peripheral ange; a gasket interposed between said peripheral ange and supporting shelf; and a cover having a friction seat wall cooperable with the friction seat wall of the top and provided also with -a downwardly lextended rib adapted to engage the peripheral flange of the cap to thereby press the latter firmly against the gasket, substantially as specified.
3. A container, of the character described including, in combination: a can body provided with a top having an opening therein, said top having an upwardly extended inner ange, horizontal gasket supporting shelf and two spaced substantially vertical friction seat walls; a cap having a countersunk central portion and a peripheral flange, the counter-sunk portion being adapted to loosely fit within the up-turned inner flange of the top; a gasket interposed between said peripheral flange and supporting shelf; and a cover having two friction seat walls cooperable with the friction Vseat walls of the top and provided also with a downwardly extended rib adapted to engage the peripheral edge of the cap to thereby press the latter firmly into engagement with the gasket, substantially as specified.
