Abstract

PURPOSE: To reduce a storage space and prevent deformation or a breakage by using three rings and bottoms, positioning outside an upper bulge on the side wall of each ring, and inside a lower bulge, forming upper bulges on the bottoms, and coupling the rings to each other and the bottoms to each other in such a state as to keep bulges in close contact with each other. CONSTITUTION: A bulge is formed on the upper and lower sections of the side walls 6 of rings A1, B2 and C3, and the upper bulges 7 are positioned outside with the lower bulges 8 positioned inside. In this case, constitution is so made that when the ring B2 is inserted in the ring A1, the lower bulge 8 of the ring A comes in close contact with the external surface of the ring B2, and the upper bulge 7 of the ring B in close contact with the internal surface of the ring A, thereby in the ring B2. Also, a bottom 4 is ring C3 is similarly inserted in the ring B2. Also, a bottom 4 is provided with an upper bulge 7, and inserted in the ring C3. In this case, a grooved leg 12 is formed on the lowest bottom and aligned with the projected holes of a base 5. Furthermore, the groove A9 of the lower bulge 8 of the ring A1 is kept aligned with the bulge A10 of the base 5 during the downward motion of the rings A1, B2 and C3.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a retractable cup.

[0002]

2. Description of the Related Art Conventional objects have a constant shape.

[0003]

DISCLOSURE OF THE INVENTION When storing in a backpack or the like as an article for a disaster or outdoors, it is necessary to (a) take a large storage space. (B) There was a risk of deformation or damage depending on the object.

[0004]

[Means to solve the problem]

(A) The rings A, B, C (1, 2, 3) are cylindrical with a hollow inside and have bulges at the top and bottom of the side wall (6). The upper bulge (7) is attached to the outside, and the lower bulge (8) is attached to the inside. When the ring B (2) is inserted into the ring A (1), the lower bulge (8) of the ring A is on the outer surface of the side wall (6) of the ring B, and the upper bulge (7) of the ring B is on the ring A (1). The inner surface of the side wall (6) is in close contact with and movable. Similarly, ring B
The structure is the same when the ring C (3) is inserted in (2). In addition, the groove A is formed in the lower bulge (8) of the ring A (1).
(9) is provided. The material should be a hard material with good sliding properties. (B) The bottom (4) is provided with an upper bulge (7) similar to the above ring on the side wall (6) to seal the lower bottom. When the bottom (4) is inserted into the ring C (3), the structure is the same as that of the ring A and the ring B. A grooved leg (12) is provided at the center of the bottom. The material should be a hard material with good sliding properties. (C) The base (5) has a hole with a protrusion at the center, and the hole diameter is made the same as the outer diameter of the leg (12) of the bottom (4). The upper surface is provided with a recess that accommodates the lower portions of the rings A, B, C (1, 2, 3). A bulge at a symmetrical position on the inner surface of the side wall of the depression A
(10) is provided at two locations, and ears (11) are provided at two locations on the outer surface of the side wall at the same position on the concentric circle as the bulge A. The material is a soft material with high elasticity. (D) Insert the rings B, C (2, 3) and the bottom (4) into the ring A (1), and press the bottom leg (12) into the center hole of the base (5) to fix it. . The groove in the bottom leg (12) and the protrusion in the hole in the base (5) are aligned with each other. (E) Rings A, B, C (1, 2, 3) on the bottom (4)
When lowered to the same position as, the groove A (9) in the lower bulge (8) of the ring A (1) and the bulge A (1 of the base (5)
0) is matched. The expandable and contractible cop having the above-described structure.

[0005]

[Function] In the height direction, rings A, B, C (1, 2, 3)
And the bottom (4) are divided into four (plural) parts, each of which is in close contact with each other and can be slidably moved, so that it can be expanded and contracted. The bulges (7, 8) above and below the side wall (6) of each portion act as stoppers to prevent the bulges from falling off.

[0006]

【Example】

(A) An item in which the cap (13) is put on the upper part of the ring A (1). (See FIG. 6) (B) As a method of fixing the bottom (4) to the base (5), there are an adhesive method, a screwing method, a screwing method, etc. in addition to the press fitting method.

[0007]

The storage space can be small if the storage is made in a contracted state. (B) Since the ring and the bottom overlap, they are not easily deformed or damaged. (C) It is hygienic even if it is stored for a long period of time if it is covered with a cap.

[Brief description of the drawings]

FIG. 1 shows a perspective view in a fully extended state.

FIG. 2 shows a perspective view in a contracted state to a minimum.

FIG. 3 shows a plan view.

FIG. 4 shows a front view (cross section AA) in a state of being extended to the maximum.

FIG. 5 shows a front view (section AA) in a state of being contracted to a minimum.

FIG. 6 is a front view (partially sectional view) of a state in which the cap is covered and maximally extended.
