FLUID-TIGHT GLASS CLOSURE FOR METALLIC CONTAINERS Filed.April 5, 1953 2 Sheets-Sheet 2 Patented Oct. 2, 1934 PATENTI OFFICE FLUID-TIGHT GLASS CLOSURE FOR METALLIC CONTAINERS Giorgio Vitale, Genoa, Italy Application April 5, 1933, Serial No. 664,623

In Italy January 16, 1933 4 Claims. (01. 220-82) This invention relates to metallic containers closed by a glass panel and is especially designed for such class of containers as used by packers for conserving foodstuff and especially assorted i hors-doeuvre, fish, vegetables and the like, for which the view of the contents is desirable, before the customer opens the container.

The known containers of this class present some inconvenience as difllcultypf manufacture and packing of the goods, considerable high cost, possibility of leakage of the preserving liquid, especially after a relatively long storage, by corrosion of the packing by the preserving liquid (generally oil or pickle) and consequent possibility of spoiling of the contents both by direct contamination'of the preserving liquid and by leakage permitting the entry of the air.

The above lamented inconveniences are overcome by the present invention, according to which 20 the glass panel forming one end of the container and provided with the usual packing ring or gasket, is so fitted as to prevent the preserving liquid from coming in direct contact with the said gasket, as the edge of the glass panel or of a part thereof co-act with the adjacent part of the wall of the container to keep the liquid contents of the container out of contact with the gasket, which thus serves only for keeping back the small amount. of liquid leaking through the adjacent 30 metallic and glass surfaces. V

' Some embodiments of the invention are shown in the annexed drawings, in which: 7

Figure 1 is a cross section and Figure 2 is a perspective view of one form of the improved container;

Figure 3 shows an elevation partially in section of another embodiment of the invention;

Figure 4 is a. partially sectional elevation of still another form of container, and

Figures 5 and 6 are plan views of the containers shown in Figures 4 and 3.

The container according, to the embodiment shown in Figures 1 and 2 comprises a metallic body 1 having a bottom connected by seaming 2. Near the upper end of the peripheral wall of the vessel a groove is pressed so as to provide an inwardly projecting bead or shoulder 3 on which the glass panel 5 rests. The panel 5 has an annular rib 7 leaving outwardly an annular rim 6 on which thepacking ring or gasket 4, that is generally made of rubber, may be fitted. It is to be noted that the width of the rim outside of the rib '7 is substantially equal to the width of the v gasket 4. 5* The glass panel 5 fits tightly within the annular space above the bead 3, being inserted in place with the annular rib '7 outwardly. Then the outer portion of the peripheral walls of the container or flange 9 is pressed or curled above the rim of the glass panel outside of rib 7 and on which rim the packing asket 4 has been previously inserted. Thus, as the annular rib 7 has aheight that is approximately equal to the thickness of the packing gasket 4 and of the flange 9, this flange in the closed container remains substantially on a level with the top of rib 7.

As it is apparent, the liquid part of the contents of this container cannot practically-leak through the parts 3 and 9' of the container and the adjacent part of the panel 5. However, should a negligible amount of liquid leak through these parts, it is kept back by the edge of the gasket 4 and remains confined between the bead 3 and the gasket.

The opening of the container is effected preferabiy by tearing an the metallic wall in correspondence of the thickness of the glass panel 5, i. e. in correspondence of the part 9'. In the case as shown the tearing takes place in correspondence of the notched lines 8, the stripkof metal between these lines being continued by a small tongue 10 to be engaged by the usual canopening key.

The glass panel serves as a lid for the opened container, as it is adapted to rest on the head 35 3, being held in place by the part of wall 9' left above the said head 3, thus insuring a'good closure of the container. The rib 7, which in the closed container serves for holding firmly in place the gasket 4 and for eo-acting with the edge of flange 9 for centering the panel 5, serves, when the container has been opened and after removal of gasket 4, as a means for taking up the panel 5 acting as a lid.

Figures 4 to 6 show two embodiments of the invention, that present the advantage that the glass panel presents outwardly a completely plane surface.

The rib 7 of panel 5 projects out of one face of the panel in such a position as to come into intimate contact with the upperportion of the peripheral wall of the container by a relatively extended annular surface. The packing ring or gasket 4 is fitted on the rim portion 6, which is preferably corrugated and the panel 5 with gasket 4' is fitted on the container so as to cause the rib 7 to co-act with the adjacent wall of the container for effecting a relatively tight closure. The end of the wall 1 is bent horizontally so as to provide an outwardly projecting flange 12 forming 1-10 11 is inserted and bent over in the usual wayand thus the wings of the said U-strip 11 grip firmly the lower edge of fiange 12 and the upper edge of the glass panel 5.

I claim:

1. A container comprising a metal-body having a bottom end connected thereto, an inwardly projecting bead formed in the wall of said body adjacent the other end thereof, a glass panel member supported by said bead and having a portion tightly fitting the interior wall of said body over a material axial length thereof exteriorly of said bead, a seat formedon the rim of said panel member in the outer face thereof, a packing member on said seat, and a continuous peripheral flange on said body turned down into engagement with said packing member to press the same against said seat.-

2. A container comprising a metal body having a bottom end connected thereto, an inwardly projecting bead formed in the wall of said body adjacent the other end thereof, a glass panel member supported by said bead and having a portion tightly fitting the interior wall of said body, an annular rib formed on the outer face of said panel member, a seat formed on the rim of said panel member exteriorly of said annular rib, a packing member on said seat abutting said annular rib, and a continuous peripheral flange on said body turned down into engagement with said packing member to press the same against-said seat.

3. A. container comprising a metal body having a bottom and connected thereto, an inwardly projecting bead formed in the wall of said body adjacent the other end thereof, a glass panel member supported by said bead and having a portion tightly fitting the interior wall of said body, an annular rib formed on the outer face of said panel member, a seat formed on the rim of said panel member exteriorly of said annular rib,-

a packing member on said seat abutting said annular rib, the said seat being of substantially the same width as the packing member and the height of said annular rib being substantially equal to the combined thicknessof the packing member and the wall of the container body, and a continuous peripheral fiange on said body turned down into engagement with said packing member to press the same against said seat with the surface of the fiange in substantially the same plane asthe top'surface of said annular rib.

4. A container comprising a metal body having a bottom end connected thereto;- an inwardly projecting bead formed in the wall of said body adjacent the other end thereof, a glass panel member supported by said bead and having a portion tightly fitting the interior wall of said body over a material axial length thereof exteriorly of said bead, a seat formed on the rim of said panel member in the outer face thereof,

a packing member on said seat, a continuous peripheral flange on said body turned down into engagement with said packing member to press the same against said seat, and a rip strip formed in the wall of the container body between the inwardly projecting bead and the peripheral fiange,

the inner edge of said rip strip being arranged somewhat above the bead to leave a shoulder above said bead to retain the glass panel in position.
