ceptacles 41 will be held spaced, as shown at 44, from the bottom 36 of the base 1, and water and steam can get under the receptacles 41, to bring about-a cooking of the material in the receptacles, and at the same time, the receptacles will not jump up anddown, and knock about, as would be the case if the steam were continually forming with the bottoms 45 of the receptacles 41 in. direct contact with. the bottom 36 of the base 1. In this connection it is to be observed that because the side wall 37 of the base 1 is bulged as sat-'38, there" is an ample space, as at 46, between the side wall 37 of the base 1,, andthe cans for receptacles 41.

As indicatedin Figure 3 of the drawings, 1 a perforated falsebottom47 maybe mounted on thefiange 39. "The false bottom 1-7 maybeused' either with or without the false bot- ;tom 14, but when the cooking operation is carried out in-connection with .thereceptacles or cans, the false'bottom 14 and the false bottom v47 are not used.

The cooking utensil hereinbefore described zcomprlses a cup-shaped base 1, an inverted cup-shaped cap 51, and-a ring 50 disposed between the base 1 and the cap 51. The base -1 and the ring 50 areprovided with detachable interengaged elements 167 which hold the base-1 and the ring 50'together, at one side ofthe receptacle, the ring '50 and the cap 51 being provided 1 with detachably interengaged elements 30 31 which hold the ring and the cap together at said sideof the re- The handles 21' which project from the base 1 and the cap 51 are located approximately 1805; remote from all of the aforesaid interengaged-elements 16-7 and 3031,the handles 21. being so spaced that the base 1, the ring 50, and the cap 51 together, atthe opposite side of the receptacle' from the aforesaid interengaged elements.

What is claimed is i 1 A cooking receptacle-provided with a necting the side wall with the bottom; the receptacle being provided with an inwardly projecting flange having seats for the reception of a cluster of contacting receptacles, the seats and the-flange.constituting means for holding the receptacles in contact with v the inclined part of the receptacle, but out of contact with the sidewall of'the receptacle, and out of contact with the bottom of the re ceptacle.

2. A cooking utensil comprising .a cupthey can begraspedsimultaneously,to hold shaped base, an inverted cup-shaped cap, and a I a ring disposed between the base and the cap,

the base and the ring being provided with del tachably interengaged elements which hold the base and the ring together at one side of the'utensil, the ring and the cap being pro- Vided with detachably interengagedelements which hold the ring andthe cap together at
