l his invention relates to containers, and more particularly to plural capacity telescopic special contour type.

This invention has utility when incorporated in'sc'tor shaped pairs of relatively telescopic sections 'to form a bottom and top. The sectional'containers may be grouped with the points converging "to forma circular assemblage for selective contentsbr knick-knacks. The individual sector shaped containers may have attractive" appeal; especially when the container wallsbe decorativfas of colored plastic. A more imiportafit us'isfor compact lunch boxes.

Referring to the drawings:

Fig. I is a perspective view of an embodiment of the invention as a container for a piece of pie, the showing being in an adjusted or but partially collapsed assembly of the telescopic sections;

Fig. 6 is a section on the line VI-VI, Fig. 5, showing the frictional holding as coacting between the sections;

Fig. 7 is an elevation of the container looking at the are shaped back or portion remote from the center or axis;

but showing the tilting of the top or cover sec;- tion as a first step in removing the bottom sec: tion therefrom, say to remove contents or to charge the container; Fig. 9 is a detail view of an inner section lug; and Fig. 10 is a reverse nesting detail view.

The container herein disclosed comprises a minor or inner section having a triangular shaped fiat bottom I with side walls rising there:- frou'n in radial portions 2, 3, from a center orapex 4. Remote from the. center 4, the radial side portions 2, 3, extend to rounded corners 5 between which is a side 6 completing the bounds about this open-top bottom section of sector form.

A somewhat larger dimension flat triangular top '5 has a pair of radially extending diverging sides 8, 9, from a center or apex it. Remote from the center 10, the side portions 8, 9, end at rounded corners Ii between which is a side l2 completingthe bounds aboutthe open bottom of this top sector formsection of the container.

The center Ill has an inward offset or ledge providing portion l3 (Fig. 2) adapted to rest on the top of the center 4. At'this register relation between the portions Ill, l3, 4, lugs 14 may slide into flare entrance grooves l5. A limit of telescopic relation is thus determined for the sides 2, {Land 3, 9, with a clearance H5 (Fig. 3) between the sides'ti, i2. At this partial telesccpic'assembly, the bottom I is parallel to the top'l. "Medially along the lower portions of the radial sides 8; 9. inward bow portions I! provide slight frictional yield sufiicient to precl ud'e fth'inner "or bottom section dropping'out when the assembled container be grasped at the ee sctiee he ras q ia o e es? e i we the iansii a f '9 se i hese revered? s? sembldcontainer elements of interfitting cup term. th r s sug st mine eleme t x i er s ieetive asp n to. rem P l n dftbe mag eas s. dear hereo not ihs e d e the friction offsets l1.

At the additional or fully collapsed relation, the centers 4, 10 are spaced so that the ledge l3 may ride clear of the top of the center 4. This reduces the clearance Hi and brings the lug or tongue l4 out of register alignment as to the groove or seat 15. A lug or minor tongue projection l8 from the bottom I adjacent the are side 6 is exposed by a notch I9 in the side [2, so that the user of the container may with a thumb or finger nail pull the minor section Fig. 8 is a section on the line VIII-VIII, Fig.7, or element away from the major element (Fig.

8) in thereby exposing more extended portions of the minor element for generous grasping in drawing the elements apart as resisted by the frictional holding means l1.

From the foregoing, it is to be understood that the degree of overlapping, or telescoping may be varied. To the extent such may be determined as partial, it may be in order to have one section with, a major Wall or flange, and the other considerably minor, but still having slip cover or telescopic interfitting coaction.

When the sections be of rigid, or substantially rigid material, there may be nicety in play-minimizing register or interfitting. This is especially important as the item may be. of substance for extended or general re-use, instead of single service. For multiple use, plastic, say as transparent or translucent may enhance sight appeal. An appropriately coated metal may be acceptable. However, for widening the use; metal may answer for baking or cooking therein, whether or not there be dough jacket therefor, a paper or fiber may be adopted; while even, as going into single service, the form itself may be edible.

While the internal rib I3 on the outer section center or corner region 4 constitutes the stop or abutment at the apex for the fractional telescopic adjustment, there is stabilizing for the outer corners H by having internal ribs 20 aligning with and extending from the ends of the grooves l5. A definite three-point suspension or holding is thus established against the ribs I4 slipping out of the grooves l5 when the stop I3 is holding.

Furthermore, with the inner section corner 4 snugly nesting with the outer section corner It, the clearance l6 does not act to have the arcs 6, l2, contribute to centralizing the relation between the partially nesting or telescoping sections. Therefore in order the more to facilitate register accuracy for the lug M with the groove IS, a wallthickening approach 2| merging with the lug l4 provides an automatic directing means for centering the inner section with its corner 4 to ride into the corner Ill against the ledge l3, so to center the arc S with the arc I2 that the lugs l4 ride directly into the grooves I5.

Streamlining, of at least one side of each of the sections may be had under the disclosure herein. The inner section (Fig. 8) has no inner lugs or grooves, and the container section is thus symmetrical for receiving a piece of pie, or other article as of food. Streamlining of the outer section may also be adopted by having outer symmetrical thickening region 22 (Fig. 10) to conceal the external location for the groove l5 as on the inside. The interfitting for plurality of telescopic volume positions, has the control means therefor on the sides as riding against each other for the respective sections.

For closed container uses, the pair of sections of cup form are assembled with the flanges toward each other.

Should occasion arise for using but one of the containers and that for open top, the smaller or inner section may be so used, with its flat side I against the top or now bottom side I of the larger section. The bottom I is bounded by an endless side wall 2, 3, 6. Complementary thereto is the top I bounded by endless side wall 8, 9, Hi. The bottom 1 and the top I are diaphragms for the respective cup elements of the container.

What is claimed and it is desired to secure by Letters Patent is:

1. The combination of a pair of plastic elements, each having a peripherally endless wall extending to a free edge in a plane, one of said elements being adapted to embrace the other in telescopic coaction between the planes defined by said free edges; one of said walls having, spaced from its plane-defining edge, ledge means inte gral with said wall and extending toward the other wall; said other wall having, spaced from its plane-defining edge, complementary seat means abutted bysaid ledge means at register therebetween to provide a first stop positively holding the elements from further telescoping, said elements having sufficient clearance between the telescoping wall portions to permit relative shifting to an out-of-register position between the ledge and seat means of said first stop, there being additional inter-element abutment means providing a second stop with one element further shifted into the other than at the first stop.

2. The combination of a pair of plastic elements, each having a peripherally endless wall terminating in a free-edge-defining plane, one of said'elements being adapted to embrace telesco-pically the other, one of said walls having ledge means integral therewith and extending toward the other wall, said other wall having complementary seat means abutted by said ledge means at register therebetween to provide a first stop, there being a diaphragm for each element bounded by its wall and coacting at the first stop in determining a first volume for the elements combined in a container at one spaced relation between said planes, said elements having interwall clearance sufficient to shift the ledge and seat means out of register for the diaphragms to approach into a second lesser volume container, there being abutting means between the elements coacting at this second volume assembly.
