Abstract

PROBLEM TO BE SOLVED: To provide paper cups which can be pulled out one by one without fail even when they are being stacked. SOLUTION: A ring-shaped frame part 3 is formed on the outer periphery of the edge 2a of an opening of a body 2 of a paper cup 1 so as to project outward. A plurality paper cups 1 can be stacked one on another, the frame parts 3 being superposed one on another. One or more protrusions 5 are provided below the frame part 3 of the body 2 so as to project from the wall surface of the body 2.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for reliably detaching a plurality of paper cups (including those made of plastic or the like) from a state in which a plurality of paper cups (including those made of plastic or the like) are fitted and stacked on a holder or the like.

2. Description of the Related Art In general, a paper cup has a frame portion which protrudes in a ring shape on the outer peripheral side of an opening edge portion of a cup body, and a plurality of the frame portions can be fitted in a laminated shape. I have.

[0002] Such a paper cup is used in a cup storage holder installed in a place shared by a plurality of persons, for example, in a vehicle such as a train or an airplane, or in a drinking water supply station such as a hospital or other facility. A plurality of cup bodies are housed in a stacked state with the opening of the cup body facing upward and vertically fitted, and are used by being sequentially pulled down from the lowermost one.

[0003]

However, in the conventional paper cups, except for those with a handle, the inner and outer peripheral surfaces of the peripheral wall portion other than the frame extending outward from the opening edge of the cup body are flat. It has a configuration.

For this reason, as described above, when a plurality of paper cups are stacked and housed in a holder at various locations in a fitted state,
The fitted flat peripheral wall parts are in close contact with each other, and when trying to remove one paper cup placed at the lowermost end from the holder etc., the adjacent upper paper cup is also pulled out at the same time, unnecessary However, there was a problem that a plurality of objects were taken out at the same time.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a paper cup which can be reliably removed one by one from a laminated state.

[0006]

In order to achieve the above object, according to the present invention, there is provided a frame which projects in a ring shape on the outer peripheral side of an opening edge of a cup body, and the frames are laminated. A paper cup having a configuration in which a plurality of paper cups can be fitted with each other, wherein one or more projections projecting from a wall surface are provided in a portion of the peripheral wall portion of the cup body below the frame portion.

In the paper cup having such a configuration, when a plurality of paper cups are stacked in a fitted state, the tip of the projection protruding from the peripheral wall surface of the cup body of one paper cup is connected to another adjacent paper cup. A gap is generated between the peripheral walls of the cup bodies of both paper cups at least around the projections of the paper cups, so that it is possible to avoid a complete close contact state. Then, since the frictional resistance between the paper cups is reduced, it is possible to solve the problem that when one paper cup is to be removed, another paper cup is simultaneously removed.

In the present invention, a plurality of projections are formed on the outer surface of the peripheral wall of the cup body, for example, at a position slightly lower than the frame portion on the opening edge side at intervals along the circumferential direction.
Thereby, the gap between the peripheral walls of the plurality of paper cups becomes uniform over the entire circumferential direction, and the paper cups can be aligned and stored with the cores thereof aligned. This projection may be provided on the inner surface side of the peripheral wall of the cup body. Various means can be applied to the molding of the projections.However, if a part of the peripheral wall of the cup body is extruded in a press molding or an injection molding, the production is easy, and the material cost is reduced, and The handling can be convenient without any trouble.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a configuration of a paper cup according to the present embodiment, and FIG. 2 is a cross-sectional view of a stacked state.

As shown in FIGS. 1 and 2, the paper cup 1 according to the present embodiment is integrally formed by using, for example, paper or plastic as a material, and a ring is provided on the outer peripheral side of the opening edge 2a of the cup body 2. It has a frame portion 3 that protrudes in a shape. A plurality of protrusions 5 protruding from the outer surface of the peripheral wall 4 are provided in a portion of the peripheral wall 4 of the cup body 2 slightly below the frame portion 3.

The projections 5 are arranged at equal intervals, for example, along the circumferential direction of the cup body 2, and each projecting amount is smaller than the frame portion 3 of the opening edge 2 a of the cup body 2.

Each projection 5 is formed by extruding a part of the peripheral wall 4 of the cup body 2 by, for example, press molding or injection molding.

According to the paper cup 1 having such a configuration, as shown in FIG.
The tip of each projection 5 projecting from the outer surface of the peripheral wall 4 of the cup body 2 of one paper cup 1A comes into contact with the peripheral wall surface of another adjacent paper cup 1B, and the two paper cups 1A, 1B around each projection 5. A gap is generated between the peripheral walls 4 and 4 of the cup bodies 2 and 2 to prevent the cup bodies 2 and 2 from being in a completely adhered state.

Therefore, since the frictional resistance between the paper cups 1A and 1B is reduced, when the lowermost paper cup (other paper cup) 1B is to be removed, the upper paper cup (one paper cup) is taken out. The disadvantage that 1A is simultaneously extracted can be eliminated.

Further, in the present embodiment, the projections 5 are provided at positions on the outer surface of the peripheral wall 4 of the cup body 2 slightly below the frame portion 3 on the side of the opening edge 2a at intervals along the circumferential direction. Since a plurality of paper cups 1 are formed, the gaps between the peripheral walls 4 of the plurality of paper cups 1 become uniform over the entire circumferential direction, and the paper cups 1 can be aligned and stored in the storage device 6 with the cores thereof aligned. .

Each of the projections 5 is formed by extruding a part of the peripheral wall 4 of the cup body 2 by press molding or injection molding, thereby facilitating the production and reducing the material cost. In addition, it is possible to make it convenient without trouble in handling.

[0017]

As described above, according to the paper cup of the present invention, a projection is provided on the peripheral wall, and a gap is formed between the cups at the time of fitting and lamination, so that the occurrence of a close contact state can be prevented. By doing so, there is an effect that it is possible to reliably pull out one by one from the stacked state.
