,, In Great Britain October 12, 1932 3 Claims. (Cl. 271'7) This invention relates to cofilns and has for its section showing, the lid portion completely enobject to provide a novel construction which is gaged with the cofiin'body. cheaper to produce than hitherto and is rot-proof Figure is a fragmentary plan view of the cofiin and leak-proof and can be closed very easily and body. 5 quickly.

Figure 3 is a detached fragmentary end view, When the lid 4 is placed on the body the flange in section showing the lid partly engaged with 5 slides down the outside of the body 1. As the coffin body. the lid 4 is pressed home, the inner surface there- 55 Figure 4 is a detached fragmentary end view in of forces the lower part of the ring 3 into the 310 deeper part of the groove in the body 1, see Figure 3, and therefore the ring 3 does 'not interfere with the passage of the flange 5 thereover. When the lid 4 is pressed into the fully closed position the triangular channel 6 therein registers with the lower part of the ring 3 and the said part springs outwardly to again occupy its original position, where it now engages the triangular channel 6 and holds the lid 4 tightly in the closed position, see Figure 4. The ring 3 also forms an air and liquid tight seal between the body 1 and the lid 4. It will be observed that screws for securing the lid are rendered unnecessary.

Figures 6 and '7 illustrate a modification in the form of closure ring. "In these figures the continuous rubber ring 8 is mounted on spring strips 9 each extending from one corner to the next of the cofiin body 10. The strips 9 are secured to the body 10 at the upper part of a continuous external groove provided in the body and of similar shape to that described with reference to the construction shown in Figures 1 to 5. The ring acts in a similar manner to the ring 3, the only difference being that the ring 3 acts entirely by its own resiliency to yield and then enter the channel in the lid whereas-the ring 8 yields and then enters the said channel by virtue of the resiliency of the spring strips 9.

I claim- 1. A self-sealing automatic catch for coffins and the like, comprising an endless element of sealing material to be seated in a groove indthe outer surface of the coffin body below the upper edge, the element being laterally enlarged in its lower portion to normally project beyond the side edge of the coffin body, the groove in the body being inwardly enlarged throughout an appropriate height to permit the element to be moved inwardly to dispose the enlarged portion substantially flush with the surface of the body, the lid of the coflin being formed on its inner surface with a channel to receive the enlarged portion of the element when the groove and channel are substantially aligned, that portion of the lid below the channel serving to displace the element, in part, into the enlarged portion of the groove to permit the free edge of the lid topass the element in the application of the lid without substantial distortion of the element.

2. An automatic self-sealing catch for coffins and the like, including an element having a lower sealing surface of endless form to seat in a groove in the exterior wall of the coffin body below the upper edge thereof, the element having a lateral extension with a downwardly and outwardly inclined upper face designed toproject beyond the surface of the coffin body when the element is within the groove, said groove being inwardly enlarged to permit bodily movement of the enlarged portion of the element inwardly of the groove to permit the enlarged portion of the element to be substantially flush with the outer surface of the coffin body adjacent the element, the lid of the coffin being formed with a channel substantially commensurate with the size and formation of the element enlargement with the channel arranged to align with the enlargement when the lid is in place, that portion of the lid below the channel serving to displace the element in the application of the lid into the enlarged portion of the groove in the application of the lid, the enlarged portion of the element moving outwardly into the channel in the lid when the channel and groove are aligned, whereby the element is seated in the groove and channel to form an interlock and bridges the space between the inner surface of the lid and the outer surface of the body to form a seal.

3. An automatically acting self-sealing catch for coilins and the like, including a sealing and locking element in endless form to seat in an endless groove in the outer surface of the coflin body below the-upper edge thereof, the lower portion of the element being laterally enlarged, and means carried by the element to insure the projection of the enlargement of the element beyond the adjacent surface of the coffin body when the element is free of inward pressure, the groove movement of the enlarged portion of the element inwardly to dispose the free edge of the enlargement substantially flush with the adjacent surface of the body of the coffin, the lid of the coffin being formed with a channel on the inner surface to be aligned with the groove when the lid is applied, said channel being of a size and shape to receive the enlarged portion of the element under the pressure of the means carried by the element when the lid is in applied position, that por tion of the lid below the channel serving to defiect the element against the tension of the means carried thereby into the enlarged portion of the groove during application of the lid.
