2 Claims.

Thislinvention relates to receptacles and particularly to covers therefor.

The object of this invention' is an improved receptacle cover which is made from a single 5 sheet of metal and which is provided with a reinforced edge.

A feature of the invention is a sealing means for the reinforced edge which prevents seepage of fluid between the at its edge.

sheet and the reinforcement -ceptacle cover which is sealed against seepage of fluid and which is designed to maintain the sealing means in place.

Still another feature is a reinforced edge for a receptacle cover which is provided with an improved seat for the receptacle.

Still another feature is a cover for, a receptacle in which the edge of the cover extends below the and receptacle.

In its preferred form, this invention comprises a cover which is made from a single sheet of metal. The edge of the cover is reinforced by folding it inward on the and the seat for the opening of the receptacle is formed by bending the folded portion downward. Sealing means, such as rubber or the like,

is inserted between the sheet and fold, and is extended around the downwardly projecting portion to cover the seat. The receptacle may beprovided with a bottle-neck and the edge of the cover may be bent over the neck to conceal the latter and improve ceptacle and cover.-

'Referrlng now to description of the invention, [0 is a receptacle the appearance of the re-" the drawing for a detailed such as the body of a washing machine, kettle, boiler, etc.,'which may be fabricated from any suitable material and may have any desirable form.

under side of the cover,

and to accumulate in the space therebetween. 5

Such fluid is removed only with difficulty and as a result remains there to decompose and give off a disagreeable odor, or to corrode the metal, or to contaminate the contentsof receptacle it].

According to this invention, seepage is prevented by inserting rubber If! or the like between folds l6 and edge l5 and then compressing the rubber therebetween. It is understood that other materials may be used, the choice depending a tainer, since the sealing means should not be readily attacked and disintegrated by the fluid To prevent rubber H from working loose, the space between edge i5 and fold I6 is made of irregular cross-section as by forming a bead I8 on fold l6. As shown; bead I8 is an external bead with respect to rubber H, but

it could likewise be made internal, that is, it could be made to reduce rather than increase the cross-section of rubber li. Several such beads may be used if, necessary.

To seat cover, It on receptacle Id, edge l9 of fold i6 is bent away from cover 14 until it 'is substantially normal to a tangent to the surface of cover M at the bend. Since cover it is dished,

this results in a conical surface which is ideal for seating purposes. To prevent direct metal to metal contact between edge l9 and rolled edge l3 of receptacle 10, with its attendant noise and unsatisfactory seal, rubber I? may be continued around both sides of edge l9 to provide a sounddeadening and fluid-tight seal between seat 93 and edge. IQ of cover I. The rubber may be made to adhere to the various portions of cover 14 with which it is in contact, by means of suitable adhesives.

Since neck I! of receptacle Ill is very short, it is possible to conceal the neck completely by the overhanging edge l5, which makes for a neat design. Furthermore, the contour of edge I5" can be made to blend with the contour of shoulder ll of receptacle l0 to render the combination of cover and receptacle more unified or streamlined in appearance. 1

It is understood that the foregoing description is merely illustrative of a preferred form of the invention and that the scope of the invention, therefore, is not to be limited thereto but is to bedetermined by the appended claims.

We claim:

1. A receptacle having an opening, and a fluidtight cover for said opening, said cover comprising a unitary metallic sheet having an inwardly and upwardly folded edge to reinforce the sheet thereat, said folded edge having a downwardly projecting flange by which the cover is centered on the receptacle, and sealing means between the inwardly folded edge and sheet for preventing the seepage of fluid therebetween and substantially surrounding said extending portion to form a seal between the cover and opening.

2. A receptacle having a bottle-neck opening,

and a cover therefor, said cover comprising a unitary metallic sheet having an overhanging portion adapted to seal the bottle-neck opening of the receptacle, 8. reversely bent portion having a region projecting into the neck and constituting the means by which said cover is centered in the opening, and sealing means inserted between the reversely bent portion and the cover and extending substantially around the inwardly projecting region to form the contacting means between the cover and opening.
