i 1 oOLLAPsIBLE DRINKING CUP.

Application filed Ma io, 1922. Serial No. 559,832.

stood that the novel features of the inven- 1e tion may be embodied in the enumerated articles and utensils.

s The primary object of my invention is the provision of a" sectional, telescopic drinking cup of this character, which may be extended tofull position for use and the sections positively'locked and supported to insure .a rigid structure. And while so extended and locked, leakage of the contents of thecontaineris prevented andv possibility 'of accidental collapse 'of the container is eliminated. y

In carrying out my invention I provide thesections or ltaperingrings of the collapsible cup with co-acting means whereby, after the cup has been extended, asimple twisting or turning movement of the sections (ex- .cept thebottom section) will cause the adjoining sections to be locked together to form a rigidstructure. And by a reverse twisting or rotary movement, the sections may successively be unlocked in order that the cup may be collapsed and the sections returned to concentric position. I

With these ends in view the invention consists in certain novel features of construction 'and combinations "and arrangements of parts as will hereinafter be more fully pointed out and claimed.

In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention wherein the parts are combined and arranged according to the best mode I have thus far devised for the practical application of the principles of my invention. 1 It will be understood that I have shown one 'exemplification ofmy invention, and that changes and alterations may be made therein, withinthe scope of my claims,witho'utdeparting from the spirit of my invention.

the section 1 when the cup is collapsed.

Figure 1 is a vertical sectional view ofla drinking cup embodying my invention, shown partly in perspective, with the cup in extended position and the cup sections v Figure 2 is a view similar to Figure 1, showing the telescoping sections before they "are turned to interlocked position.

Figure 3 is a vertical sectional view in perspective showing the cup in collapsed position.

Figure 4 is a face view of a portion of two sections showing the locking elements.

Figure 5 is a vertical sectional view at line 5'5 of Figure 4L. i In the form of the invention as shown in the drawingsI utilize a comparatively broad base or circular disk .A composed of suitable material and provided with a countersunk center or recess B m which the bottomring or section 1 of the cup is fixed, as by means of the flange A on the bottom A of the section 1.

Four telescopicsections, or tapering rings, are illustrated in the drawlngs and designated 1, 2, 3, and 4, but it will be understood that a greater or less number ofsections may be utilized if desired. These telescopic sections or taper ng rings increase in diameter 1, and they'may be stamped from light metal to proper size and shape, or other suitable material may be, used in the composition of these sections. hen the cup is extended the sections are in frictional contact, but in many instances, and due to frequent causes, while the friction is sufficient to prevent leakage, the friction is not adaquate for the support of the sections to holdthe cup cx- Forthis purpose I provide p ositive locking means, comprising co-acting members on adjacent sections, which when brought into proper relationship [will lock the sections of-the extended cup into a rigid structure.

It will be seen that the bottom section 1 is provided with. a plurality of vertically disposed, exterior protuberances or heads 5, spaced at regular intervals around the section. The second section 2 is provided with a complementary set of interior sockets 6, which, when alined with the exterior-heads 5 will permit the section 2 to telescope over W n the cup is extended the section 2 is. no

turned slightly to move the head and socket out of alinement or register in order that the head may be engaged with the section 2 to retain the latter in uplifted position.

Sections 3 and 4: are each provided with a series of interior vertically disposed heads 5 adapted to be locked with the upper enclosed edges of the sections 2 and 3 when the cup is extended.

Intermediate sections 2 and .3 are fashioned with exterior recesses or sockets 6 complementary to the sets of heads 5, and these sockets are adapted to receive their heads when the sockets and heads are alin'ed and the cup is collapsed. Thus it will be apparent that with the complementary series of sockets and heads in alined position, the extended cup may be collapsed by pressure on the top section to telescope the sections, and the bosses 7 of the heads are seated in the sockets. i

In locking the sections of the extended cup, the sections are successively turned, and this relative, successive movement of the sections is limited. Thus the locking ends of the heads are fashioned with transversely extending, inclined shoulders 8, which when the cup is extended are situated partly out side their sockets, and adapted to engage with the edge, 10, of the sockets as 6 at the rim of a section. As one section is turned with relation to another section this inclined shoulder acts as a wedge at the point 10 to tighten the sections of the cup and render them leakproof. The end, 11, of the inclined shoulder, 8, is disposed at all times within its socket and thus by contact at the point- 10 the shoulder limits the relative movement of the adjoining sections when they are turned, and the motion of one section is successively imparted to a succeeding section, until all are locked together.

Upon reverse rotary movement or turning of the sections to collapse the cup, the point 11 of the shoulder 8 contacts with the wall of a socket at 10, and the rotary motion is thus imparted successively to the sections. When all the sections have been freed from the wedging action of the inclined edges or shoulders, the sections may be telescoped to compact concentric position.

It will thus be apparent that by holding the bottom section of the container in one hand, the top section may be grasped by the other hand and pulled, and as each succeeding section is frictionally engaged with the preceding section, the sections are successively drawn out to extend the container. Then by a twist'of the wrist, the sections are successively locked together by wedge action and the container is ready for use. The sockets are of such size in relation to the angle of taper of the cup as to be completely covered by the adjacent section or ring, thus insuringagainst possibility of leakage when the cup is extended.

In collapsed or telescoped position, the bosses T of the heads are seated in the sockets, while the greater portions of the heads are located between the walls of the concentric sections. IVhile the heads and sockets are referred to as being stamped from the walls of the sections, it will be obvious that these elements may be fashioned in other manner, and it will also be apparent that the dimensions of the sockets and heads, and the numberutilized, may be varied. The size of the sets of sections may also be varied, depending upon the nature of the re,-

ceptacle or container and its uses, and other changes may be made within the scope of my appended claims.

In claims 1, 2, and 3, telescoping section refers to the narrower section ,Which pasess socket portion on the edge of the adjoining telescoping section to permit collapsing whereby when the container is extended and its sections relatively turned, the projecting head on one section engages against the edge of the adjoining section and the sections are.

locked together.

2. The combination in a collapsible container composed of telescopic tapering sections, of an exteriorly projecting head on'a 'ioo telescoping section and a complementarysocket portion on the edge of the adjoining telescoped section to permit collapsing whereby when the container is extended and its sections relatively turned, the head on one section engages against the edge of the adjoining section and the sections are locked together. i

3. The combination in a collapsible container composed of telescopic tapering sections, of a head on one section and a complementary socket portion on the edge of the adjoining section, the head formed so as to engage the edge of the adjoining section in extended position; and to keep coupled with its socket in collapsed ajndfpartly collapsed positions.

4. The combination in a collapsible container composed of telescopic tapering sections of a headon one section and a complementary socketportion on the edge of the adjoining section, the head having a shoulder inclined to the horizontal, adapted to engage the wall ofits socket as described.
