Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a combination cup having a plurality of inner cups that can be stacked in a multi-tiered manner and put together into one, and two outer cups that accommodate these cups.

[0002] This type of assembled cup is widely used as a beverage tableware for picnics or hiking because it allows a plurality of cups to be carried together. The individual cups that compose the assembled cup are formed in a generally tapered shape with a downward constriction, and arbitrary cups can be placed in other cups and stacked in multiple stages.

[0003]

[Problems to be solved by the device]

 In many cases, the assembled cup is formed by injection molding, and the inner and outer surfaces are smooth. Therefore, if multiple cups are stacked in multiple stages, the mating surfaces will stick together and it will be difficult to separate them. In particular, when the mating surface is wet with water or a beverage, a water film is formed between the mating surfaces, which prevents the passage of air, making it more difficult to separate the cup.

Conventional cups also have problems in use. In most cases, the bottom of the cup is flat. Therefore, if the cup is placed on uneven terrain or on a rock, the cup tends to tilt or wobble and cannot be placed in a stable state. Further, the opening edge of the cup is also formed flat like the bottom wall. Therefore, when the cup after washing is dried while lying down, if the lying surface of the cup is flat, the air in the cup is closed and it is difficult to dry.

An object of the present invention is to provide an easy-to-handle assembled cup that can be easily separated and operated even when it is difficult to separate the cups that are stacked in multiple stages. The purpose of this invention is to enable the cup to be placed in a stable state that is difficult to wobble even on irregular surfaces such as rock surfaces. The purpose of this invention is to make it possible to accelerate the drying of the cup after cleaning, regardless of the state of the lying surface of the cup.

[0008]

[Action]

 In a state where a plurality of inner cups 1 are stacked, the inner cup 1 on the upper stage side is fitted into the inner cup 1 on the lower stage side, and the lower surface of the step portion 4 provided on the upper part of the cylindrical peripheral wall is the inner cup on the lower stage side. It is received by the open end surface 5 of the cup 1. At this time, when the corrugated surfaces of the upper and lower inner cups 1 and 1 and the opening end surface 5 are in close contact with each other, and when the upper and lower protruding surfaces of the corrugated surface are in contact with each other Is in any of the states. In the former case, holding adjacent inner cups 1 with both hands and rotating one of the inner cups 1 in rotation causes a component force in the central axis direction of the cup in the inclined part of the corrugated surface. Due to the component force, adjacent inner cups 1 and 1 can be reasonably separated from each other in a direction away from each other. Therefore, even when a water film is formed between the fitting walls, the stacked inner cups 1 can be easily separated by the cam action of the corrugated surface. In the latter case, since a gap is created between the fitting walls, the inner cups 1 and 1 do not come into close contact with each other. The pair of upper and lower outer cups 2 and 3 can also be easily separated by the cam action between the step portion 9 and the opening end surface 14 in the same manner as described above.

In the assembled cup in which the three mounting legs 7, 10 and 11 are bulged on the bottom walls of the inner and outer cups 1, 2 and 3, the three mounting legs 7 and 10 and 11 are Contact the mounting surface. Therefore, when placing cups 1, 2, and 3 on a flat surface, and when placing cups 1, 2, and 3 on an irregular surface, the three points on the bottom of the cup should contact the irregular surface. It can be maintained in a stable state without wobbling. In other words, even if it is an irregular surface, if there are three uneven surfaces on the same horizontal surface, the cups 1, 2 and 3 can be placed horizontally and stably.

[0010] The corrugated surface formed by an integral number of smoothly continuous convex surfaces 6a and concave surfaces 6b as one unit can be formed on either the forward or reverse side when separating the closely-attached cups 1 and 1. Since it can be rotated, it is convenient because there is no restriction on the direction of rotation during separation. The projection 12 and the groove 13 provided between the fitting surfaces of the first and second outer cups 2 and 3 engage with each other in a concavo-convex manner to maintain the joined state of both outer cups 2 and 3. Therefore, even when only one of the outer cups 3 is held in the hand, it is possible to prevent the other outer cup 2 from coming off due to the weight of the inner cup 1. The corrugated surface forming the stepped portion 9 and the opening end surface 14 of both outer cups 2 and 3 forcibly releases the fitted state between the projection 12 and the groove 13 to separate the outer cups 2 and 3 from each other. To facilitate.

[0011]

Embodiments FIGS. 1 to 4 show an embodiment of an assembled cup according to the present invention. In FIG. 1, the assembled cup is composed of three inner cups 1 that can be stacked in a multi-tiered manner and a pair of upper and lower outer cups 2 and 3 that accommodate the stacked three inner cups 1.

In FIG. 2, an inner cup 1 having an open upper surface is made of an injection-molded product made of a plastic material and has a circular cross section. The inner cup 1 is provided with a peripheral wall 1a in the shape of a downwardly tapered taper, and a bottom wall 1b that is continuous with the peripheral wall 1a, and a step portion 4 extends in a circular shape on the upper outer surface of the peripheral wall 1a. The peripheral wall portion above the step portion 4 is formed to have a diameter larger than that of the peripheral wall portion below the step portion 4 by the amount of protrusion of the step portion 4.

In order to easily separate and operate the inner cups 1 stacked in multiple stages and having the fitting walls in close contact with each other, the preceding step portion 4 and the opening end surface 5 of the inner cup 1 can be in close contact with each other. Form on the surface. As shown in FIG. 3, the corrugated surface is composed of a convex surface 6a and a concave surface 6b that are smoothly continuous in the circumferential direction. The corrugated surface including one concave and convex surface 6a and 6b is defined as one unit, and is formed by an integral number thereof. . In this example, the corrugated surface was formed with a waveform of 3 units. When the inner cups 1 are stacked, the step portion 4 of the upper inner cup 1 is received by the opening end surface 5 of the lower inner cup 1 to define the fitting limit of both cups 1 and 1. There is.

The bottom wall 1b of the inner cup 1 is provided with three mounting legs 7 for stably mounting the cup on an irregular surface. The mounting leg 7 is formed by bulging the corner portion of the bottom wall 1b downward. The mounting legs 7 are adjacent to each other at equal intervals in the circumferential direction.

The pair of upper and lower outer cups 2 and 3 are injection molded products made of a transparent plastic material, and each of them is a container having a circular cross section. As shown in FIG. 1, among the outer cups 2 and 3, the stacked inner cups 1 are housed in the lower first outer cup 2 having an open upper surface. Further, the second outer cup 3 is fitted into the first outer cup 2 while covering the inner second cup 3 with the upper second outer cup 3 whose bottom surface is open, so that a total of five cups 1, 2 ... 3 can be put together as one set cup. That is, the outer cups 2 and 3 are in a relationship of a lid and a main body of the cylindrical container.

In FIG. 4, the first outer cup 2 is composed of a peripheral wall 2 a that is slightly larger than the inner cup 1 and a bottom wall 2 b that is continuous with the peripheral wall 2 a, and forms a step portion 9 on the upper inner surface of the peripheral wall 2 a. The peripheral wall diameter above the step portion 9 is larger than the peripheral wall diameter below the step portion 9. On the bottom wall 2b, three mounting legs 10 having the same purpose as the inner cup 1 are bulged.

The second outer cup 3 is a cylindrical container having a peripheral wall 3 a which is slightly larger than the inner cup 1 and a bottom wall 3 b (an upper wall in the state of FIG. 1) connected to the peripheral wall 3 a. Three mounting legs 11 having the same purpose as the inner cup 1 are bulged and formed on the wall 3b. The opening surface side of the peripheral wall 3a is fitted into the first outer cup 2 in a lid-fitting manner, and the outer cups 2 and 3 form a tea-tube-shaped container. In order to maintain the joined state of both outer cups 2 and 3, between the fitting surfaces of both outer cups 2, that is, the inner surface of the peripheral wall above the step portion 9 of the first outer cup 2 and the open end of the outer surface of the peripheral wall of the second outer cup 3. A protrusion 12 and a groove 13 that engage with each other in a concavo-convex shape are formed in a circular shape on each of the sides. In this embodiment, the protrusion 12 is provided on the second outer cup 3 side.

In order to forcibly release the engagement state between the projection 12 and the groove 13 and separate both outer cups 2 and 3, they are received by the step portion 9 of the first outer cup 2 and the step portion 9. The open end surface 14 of the second outer cup 3 is formed by a corrugated surface that can be in close contact with each other. Like the corrugated surface of the inner cup 1, this corrugated surface is formed by a convex surface 6a and a concave surface 6b of 3 units. The opening end surface 15 of the first outer cup 2 is also formed in the same corrugated surface as the step portion 9.

In the assembled cup configured as described above, the three inner cups 1 stacked in multiple stages are housed in both outer cups 2 and 3 and carried. When using, hold both outer cups 2.3 with both hands, and rotate one of the cups around the cup center axis to separate both outer cups 2.3. At this time, in the inclined portion of the corrugated surface between the stepped portion 9 and the opening end surface 14, a component force in the cup central axis direction is generated, and the joined outer cups 2 and 3 are moved in opposite directions. Therefore, the engagement between the projection 12 and the groove 13 is forcibly released, and the outer cups 2 and 3 can be easily separated. The three stacked inner cups 1 can also be separated in the same manner as the outer cups 2 and 3 by rotating adjacent cups. As described above, the step portions 4.9 of each cup and the opening end faces 5 and 14 exhibit the function of the end face cam.

Each of the inner and outer cups 1, 2 and 3 is equipped with three mounting legs 7, 10 and 11, respectively. Therefore, if each cup 1, 2, 3 is placed on an irregular surface such as the surface of a rock, each cup 1, 2, 3 contacts the irregular surface at three points, and the placement posture can be stably maintained. . Both outer cups 2 and 3 are made of transparent plastic material. Therefore, at the time of sale, it is possible to check at a glance that the three inner cups 1 are housed inside, and it is possible to prevent misplacement of the inner cup 1 well. Since the opening end surfaces 5, 14, and 15 of each cup 1, 2, and 3 are formed in a corrugated surface, respectively, the drying can be promoted when the cup is washed with the opening surface facing down and drained. This is because even if the prone surface is flat, air can enter the cup through the corrugated surface and promote drying of water droplets on the inner surface of the cup.

In addition to the above embodiments, the corrugated surface can be formed in a saw-tooth shape or a trapezoidal shape as shown in FIG. The convex surface 6a and the concave surface 6b may be provided in one unit or more in the circumferential direction. The number of the inner cups 1 may be any number as long as it is 2 or more. Only one of the outer cups 2 and 3 may be transparent or translucent. The mounting legs 7, 10 and 11 may be provided so as to project below the flat bottom walls 1b, 2b and 3b as shown in FIG.

[0022]

[Effect of the invention]

 According to the assembled cup of this invention, even when the inner cups 1 stacked in a multi-stage form come into close contact with each other or a water film is formed on the close contact surface to make separation difficult, the inner cups 1 adjacent to each other are only slightly rotated. Thus, a component force in the cup center axis direction is generated between the step portion 4 and the opening end surface 5 which are in close contact with each other, so that the inner cups 1 can be easily separated from each other. Since three mounting legs 7, 10 and 11 are provided on the bottom walls 1b, 2b and 3b of the inner cup 1 and the outer cups 2 and 3, respectively, so that the cups 1 to 3 can be placed without wobbling. It is convenient for outdoor use such as hiking and picnics. When the cups 1 to 3 after washing are placed on a flat surface wall to drain water, air can be vented into the cup through the corrugated opening end faces 5.14.15, so that water droplets adhering to the inside surface of the cup can be dried. Can be promoted.
