` lClaim.

This application is a division of application Serial No. 110,573 filed November 13, 1936 and now matured into Patent No. 2,279,356.

'I'his invention relates to compacts, refills, containers, cartons and the like, and particularly to a novelfastening means therefor.

One object of the invention is a reiillable compact characterized by simplicity in construction, the economy with which it may be manufactured and the facilitywith which it may be refilled.

A further object of the invention is a novel fastening means which may be employed for rellable i compacts, boxes, lids, shields for radio tubes, containers, etc.

Further objects of the invention will hereinafter appear- Vand Fig. 7 is a plan view illustrating the fastening of the insert in the casing.

Referring to the drawing and particularly to Figs. 1 to 5, I have illustrated a compact embodying one form of my invention. The invention is embodied in a compact I, having a bottom 2 and a lid 3, and it isunderstood that the compact may be of any shape, form or construction desired, so long as itembodies the refillable fastening feature of the invention. The refill is indicated at 4 and this embodies a base 5 which is compacted on its upper surface with powder B or the like to be carried by the base 5. The base 5 of the refill carries on the underside thereof a fastening tongue 1 which is tapered in width, as indicated,

` and.which is curved to have on one side a convex edge 8 and on its other side a concave edge 9. In

`the particular embodiment shown the tongue'l is soldered, welded or otherwise fastened to the base 5 or it may be provided with an integral fastening clip IIl which is passed through a slot II formed in the base 5, extended along the upper surface of the base 5 to the periphery thereof, and then passed around the edge to and in contactwith the lower surface thereof. The clip I0 thus forms a U-grip about the edge of the base 5. Cooperating with this fastening tongue I is a tongue I2 fastened to the bottom 2 of the casing. This tongue I2 extends inwardly from a main body part I3 lying flat against the bottom 2 and soldered or otherwise fastened thereto. The body part I3 i may, if desired, also be fastened to the bottom 2 by means of an integrally formed clip I4 which is passed downwardly through a slot I5 formed kin the bottom 2 and then extended outwardly along the bottom surface of the bottom 2 to the peripheral edge I6 of the casing where it then passes through another slot or opening similar to I5 and the end I'I of the clip is then flattened against the upper surface of the bottom 2 as shown in the drawing.

With the construction shown, the rell 4 may be readily inserted in place or removed from the casing with the tongue I2 extending beyond the center of the casing, and with the particular form and shape of the tongue I the inserting and removing operations are simplified and facilitated. For example, when it is desired to remove an insert 4, a combined pressing down and twisting movement of the rell with respect to the bottom casing will facilitate the disengagement Vof the tongue I from underneath the tongue I2.

Similarly, when the rell 4 is inserted, it is first positioned in the casing with the tongue I or the outer end thereof disposed to one side of the tongue I2, whereupon the refill is given a similar movement to bring the tongue 'I underneath the tongue I2, as indicated in Fig. 7, the turned up end of tongue I2 (Fig. 2) facilitating the engagement. The insertion of a refill may be effected by positioning the same on the shallow bottom part 2 with the tip of the tapered tongue 'I in a position to slide under the tip of the tongue I2 and then imparting to the rell and the bottom part 2 relative sliding and rotary movements to bring the concave side-9 of the tongue I into the position indicated in Fig. '7. The refill and fastening means for the refill Vand case may be very inexpensively manufactured on a quantity production basis and the rell may be removed very simply and with the greatest facility without the need for any special tools. Practice has demonstrated that the particular shape of the tongue 1 with the convex and concave sides contributes toward and facilitates the interlocking and disengagement operations.

VI claim:

A compact comprising a circular casing having a bottom and a diametrically positioned metallic tongueiajttaichedatwone-:end only` at' against the inner surface of said bottom and extending from the line of attachment to a point beyond the center thereof and a flat circular reiill having a K base plate with a cooperaitng tongue similarly attached at against the bottom surface thereof 10 edge lying against said line of attachment.
