The guide groove 12 is formed in a "C" shape as a groove in which a guide projection 21 formed in a lower container 20 described later is inserted and guided. That is, the guide grooves 12 are formed by vertically extending grooves formed in the vertical direction of the upper container 10 and horizontally extending upper grooves and lower grooves formed at the upper and lower ends of the grooves, .

2, bottleneck grooves 12b and 12d having narrow widths are formed at the respective ends of the upper horizontal groove and the lower horizontal groove, and then the width of the bottleneck grooves 12b and 12d is increased again, 12a and 12c are formed to be engaged with each other.

The lower container 20 is cylindrical in shape and has an upper surface opened. The lower surface of the lower container 20 is closed by the pedestal portion 24, and a pair of guide projections 21 are formed.

That is, the guide protrusion 21 is coupled to the guide groove 12 of the upper container 10 and moves in a sliding manner along the guide groove 12, as described above, The protruding degree of the guide protrusion 21 is substantially equal to the depth of the guide groove 12 of the upper container 10 A slightly smaller size is preferable.

The diameter of the guide protrusion 21 is preferably substantially the same as the width of the bottleneck groove 12b or 12d of the guide groove 12. The material of the guide protrusion 21 is preferably rubber having good elasticity, . Therefore, the thickness (diameter) of the guide protrusion 21 is smaller than the width of the other part of the guide groove 12 except the bottleneck groove portions 12b and 12d.

A packing 22 is formed adjacent to the lower end of the guide protrusion 21 to surround the outer circumference of the lower container 20. The packing portion 22 is preferably formed of a rubber member having good elasticity and adhesion to prevent leakage of the beverage when the beverage is contained in the tumbler.

Next, the engaging state of the tumbler according to the first embodiment of the present invention and an operation method thereof will be described in detail.

The tumbler according to the first embodiment of the present invention is characterized in that the upper portion of the lower container 20 is accommodated in the lower side of the upper container 10, The guide protrusions 21 of the upper container 10 are inserted into and coupled to the pair of guide grooves 12 of the upper container 10, respectively.

Accordingly, the guide protrusion 21 of the lower container 20 is moved upward along the vertical groove of the guide groove 12 of the upper container 10, and then the upper end of the vertical groove is horizontally Direction.

At this time, since the thickness (diameter) of the guide protrusion 21 is smaller than the width of the vertical grooves or horizontal grooves of the guide grooves 12, it is possible to move smoothly. However, The diameter of the guide protrusion 21 is substantially equal to the width of the bottleneck groove portion 12b so that the guide protrusion 21 is caught by the bottleneck groove portion 12b appear.

However, since the thickness (diameter) of the guide protrusion 21 is substantially equal to the width of the bottleneck groove portion 12b and the guide protrusion 21 is made of a rubber material having good elasticity, The protrusion 21 smoothly passes through the bottleneck groove portion 12b and adheres to the binding groove portion 12a.

3 (b), the lower container 20 is inserted into the upper container 10 and folded in the state that the guide protrusion 21 is engaged with the binding groove 12a, So that it becomes easy to carry. Since the bottleneck groove portions 12b and 12d serve as stoppers in a state where the guide protrusion 21 is engaged with the binding groove portion 12a, the guide protrusion 21 may be freely moved out of the binding groove portion 12a It is possible to prevent unforeseen situations.

Next, in order to use the beverage in the tumbler, as shown in Fig. 3 (a), it is preferable to unfold the tumbler in the usual form. The upper container 10 is moved in the direction opposite to the direction in which the upper horizontal groove is formed so that the guide protrusion 21 attached to the binding groove 12a is removed from the bottleneck groove 12b, (20) is rotated in the same direction as the direction in which the upper horizontal grooves are formed. The guide protrusion 21 comes out of the bottleneck groove 12b by the pressing force of the upper container 10 and the lower container 20, The guide protrusion 21 moves along the upper horizontal groove and when the lower container 20 is pulled downward (or the upper container 10 is pulled upward) at a portion where the upper horizontal groove and the vertical groove are in contact with each other, The guide protrusions 21 are moved downward along the vertical grooves so that the lower portion of the lower container 20 is unfolded outwardly of the upper container 10.

When the upper container 10 and the lower container 20 are rotated in the horizontal direction so that the guide protrusion 21 moved downward along the vertical groove moves along the lower horizontal groove as described above, The guide protrusion 21 is caught by the bottleneck groove 12d whose width is narrowed. However, as described above, by the pressing by the force of horizontally rotating the upper container 10 and the lower container 20, The guide protrusion 21 passes through the bottleneck groove 12d and is adhered to the binding groove 12c.

As described above, when the guide projection 21 is engaged with the engagement groove portion 12c, the tumbler is firmly fixed in a deployed state as shown in Fig. 3 (a).

A packing 22 surrounding the outer periphery of the lower container 20 adjacent to the lower end of the guide protrusion 21 is provided in the upper container (not shown) 10 and a part of the outer circumference of the lower container 20 is in close contact with the extended portion 13 formed inward from the lower edge of the body 11, It is possible to prevent a beverage or the like in the tumbler from leaking along the surface in contact with the upper container 10 and the lower container 20.

Therefore, the height of the packing part 22 is set such that when the guide protrusion 21 is engaged with the binding groove part 12c of the lower horizontal groove, the outer end of the packing part 22 is inserted into the body of the upper container 10 And it is preferably formed to such an extent that it can be brought into close contact with the inner surface of the base 11.

When the guide protrusion 21 is engaged with the fastening groove 12c of the lower horizontal groove, the outer end of the packing 22 is brought into close contact with the inner surface of the body 11 of the upper container 10 And the inner space of the upper container 10 is widened toward the upper side so that the packing portion 22 prevents the upward movement of the guide protrusion 21 .

The inclination of the inner space of the upper vessel 10 is such that the horizontal distance deviation between the upper side and the lower side is larger than the projecting distance of the guide projection 21 The guide projections 21 are engaged with the guide grooves 12d in the lower horizontal grooves of the upper container 10 so that the guide projections 21 are engaged with the guide grooves 12d, The guide protrusion 21 is moved arbitrarily while a beverage or the like is put into the tumbler and the tumbler is used and the connection between the upper and lower vessels of the tumbler becomes unstable, It is possible to prevent an accident from occurring.

It is preferable that magnets are embedded at both ends of the helical guide groove 15 and at both ends of the helical guide protrusion 25. [

Accordingly, when the tumbler is not used, the lower container 20 is rolled up to the inside of the upper container 10 to make it easy to store and carry the tumbler in a folded form. When the tumbler is intended to be used with a drink or the like, The lower container 20 is unfolded to the lower side and used by extending it to the size of a normal tumbler.

In this case, since the inner space of the tumbler is narrowed downward as described above, when the size of the tumbler is increased, the lower container 20 is loosened to the lower side of the upper container 10, The gap between the guide groove 15 of the upper container 10 and the guide protrusion 25 of the lower container 20 becomes narrow and finally the gap between the inner diameter of the upper container 10 and the outer diameter of the lower container 20 becomes equal The gap between the guide groove 15 of the upper container 10 and the guide protrusion 25 of the lower container 20 disappears and tightly adhered tightly. The magnet embedded in the lower end of the spiral guide groove 15 and the magnet embedded in the lower end of the helical guide projection 25 are engaged with each other to thereby form a coupling force between the guide groove 15 and the guide projection 25 .

As described above, when the tumbler is used in an extended size, the guide groove 15 and the guide protrusion 25 are closely contacted with each other without any clearance, so that a separate packing member for preventing the beverage from leaking in the tumbler is unnecessarily do.

When the tumbler is folded for easy carrying or storage, the lower container 20 is folded up to the inside of the upper container 10. At this time, the guide groove 15 and the guide protrusion 25 The magnet embedded in the upper end of the helical guide groove 15 and the magnet embedded in the upper end of the helical guide protrusion 25 are engaged with each other Since the coupling force between the guide groove 15 and the guide protrusion 25 is reinforced, the folded state of the tumbler can be maintained.
