Specification of Letters Patent.

Application filed September 24, 1919. Serial No.-826,039.

Toallwlwmitmay concern:

Be it known that I, THoiuAs H. FRENCH, a sub'ect of Great Britain, residing at Pacific rove, in the county of Monterey and State of California, have-invented certain new and useful Improvements in Sealed Containers, of which the following is a specification.

This invention relates to containers and more particularly to a hermetically sealed, metalllc container having a window through which the contents may be seen.

It is one of the objects of the present invention tov provide a simple, substantial, practicable, durable and inexpensive display metallic container adapted for receiving the material to be contained therein and constructed in such manner as to be capable of withstanding the heat and pressure during the processing of the contents thereof sealed therein. It is the special object of the present invention to provide an attractive and ornate container provided with a sealed window at one end through which the contents of the container may be seen.

With these and other objects-in view the invention consists of the construction, the

. combination, and details and arrangement invention illustrated in the accompanying 5 6 posed a suitable packing ring or material 4 of the parts as more particularly described hereinafter relative to the embodiment of the drawings, wherein- Figure 1 is a perspective view of the complete and sealed container.

Fig. 2 is a longitudinal vertical section through the container.

While the type of retainer herein referred to usually is made of tin or other thin material, it is obvious that any suitable material may be employed. Also while the tin or can is here shown as being substantially elli tical in form, it may manifestly be ma e in any desired shape and proportion and size. In the present case the container comprises a tubular shell or wall 2 the upper or top end of which is turned inwardly, indicated at 3, and in this instance shown as formed integrally with the wall or shell 2, although it may be made of separate material and suitably. connected to the wall. This rim forms a frame like bezel and is preferably of plane or lano-convex form, the concave surface being turned inwardly. In the concavity of the rim or flange 3 there is disagainst which is pressed a glass plate 5. Against the inner surface and edge portion of the glass plate 5 or window there is laid a washer or packing ring 6 the top face of which is preferably black or dark, so that it can notbe seen when looking through the window. This packing ring is held in place by an inner seat or flange 7 which is pressed down upon the packing ring and while clamped firmly in position is sealed or soldered as at 8 to be permanently connected to the wall or shell of the can. After the window is thus hermetically and permanently sealed in position, the open end of the can is then turned upright and placed so that the can can be filled to the desired degree, as, for instance, with fish or other material. For the purpose of making an ornate and attractive container for displaying the goods, the contents of the can may be pressed firmly against the window 5 by means of a follower in the form of a plate or sheet of material 9 conforming to the cross sectional rear of the-can 2 to which may be attached or against which may react a spring 10 which will bear against the permanent end closure or bottom 11, preferably double seamed to the lower edge of the body 2, providing a permanently and hermetically sealed display container.

By this method a can or container which is simple, practicable, attractive and capable of withstanding the pressure and heat of processing may be made and the contents or the goods of'the can clearly displayed tothe customer orv patrons of a store or other institution in which the goods maybe arranged for display.

Having thus described my invention, what I claim as new and desire to protect by Letters Patent is 1. A hermetic display container comprisin a tubular shell having its wall surface ad acent its upper peripheral edge disposed in the same plane as the main body port on of. the shell and curved inwardly provld ng an unbroken continuous flange overhanging the interior of the shell, an innen sealing means secured to the inner surface of the shell and with said .flange providing a seat of an exterior diameter corresponding to the inner diameter of the shell, a transparent closure member held between said flange and sealing means, a washer intermediate opposite faces of the transparent closure 11c member and the flange and sealing means, and a closure sealing the opposlte end of the shell.

2. A hermetic display container comprising a tubular shell formed on its interior adjacent its upper end with an annular seat of a diameter not exceeding the inner diameter of the shell, one wall of said seat being formed by bending the upper peripheral edge of the shell inwardly to overlie the interior of the shell, a transparent closure member held in said seat, a packing between the opposite faces of the seat and closure member, and a closure sealing the opposite end of the container and double seamed to the lower edge of the shell.

3. A. hermetic display container comprising a tubular shell formed on its interior adjacent its upper end with an annular seat of a diameter not exceeding the inner diameter of the shell and formed of spaced walls of concavo-convex cross section, one of said Walls being formed by bending the peripheral edge of said shell inwardly, a W111- dow plate closing the upper end of the shell and with its periphery held between the seat forming walls, a packing associated with each wall between the same and the surface of said closure plate, a closure plate for the lower end of the shell, and afollower plate within the container for pressingthe contents thereof against the under face of the window plate.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

THOMAS H. FRENCH.
