Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention relates to a paper cup, and more particularly to a paper cup that can be used as a megaphone after drinking.

(Prior Art) In recent years, drinking paper cups are often used because they can be thrown away as they are, but it is preferable that such paper cups be used for something instead of being thrown away after use. From the shape of the cup, it can be considered to be used for a megaphone, but as an example of a cup that can be used as a megaphone, there is No.
There is a publication such as 1-63680. The cup disclosed in Japanese Utility Model Laid-Open No. 1-110178 is constructed by inserting a plug having a sealing material such as an O-ring on the outer periphery into the mouth of a trumpet-shaped body and removing the plug after use. The main body is used as a megaphone. The material of this cup is not particularly limited, but it can be expected that a certain degree of solid material such as plastic is suitable, and it can not be rolled up and discarded, and since the number of parts is large, the cost is too high to be disposable. There is a problem. Further, if it is a paper cup, it can be expected that the plug insertion will not be firm and there will be a problem with the sealing property. Further, there is a concern that the paper itself may be softened by the liquid contents during use and the sealing property may be further deteriorated, thereby failing to serve as a cup. On the other hand, the paper container of Jitsukaihei 1-63680 has a structure in which the lower end of the wide mouth of the trumpet-shaped peripheral wall is closed with a lid, and the tapered upper end is opened with a top plate so that the lid and the top plate can be removed after use. It was designed to use the trumpet-shaped peripheral wall as a megaphone. Although this container is made of paper, it is for storing solid substances such as confectionery, not for storing liquid such as beverages. Therefore, the top plate is simply bonded so that it can be easily removed, or is provided with perforations, and no consideration is given to the sealing property against liquid.

(Problems to be Solved by the Invention) In view of the above situation, the present invention aims to provide a paper cup that can be used as a megaphone after being used while sufficiently fulfilling the function of the conventional paper cup.

(Means for Solving the Problems) In order to solve the above problems, in the present invention, the bottom of a paper cup having a trumpet-shaped peripheral wall, an annular outer peripheral portion that can be inserted into the lower outer periphery of the paper cup, and A paper cup is constructed by inserting a mouthpiece, which is disposed inside the annular outer peripheral portion and has a sharp protrusion capable of cutting the bottom surface of the paper cup.

(Function) The paper cup that can be used in the present invention is not particularly limited, and any kind of paper cup can be used, but beer cups that are sold at the spectator of a ball stadium are particularly suitable.

The mouthpiece may have a simple cylindrical shape or a constricted shape, but preferably has a flat end portion so that beer or the like can be placed. Further, the sharp protrusions may be one or a plurality of discontinuous ones arranged on the circumference, or may be a saw-like annular continuous one. Further, it may be a conical projection that simply pushes down the bottom surface. The support of the paper cup by the mouthpiece in a state where the contents are put in the paper cup may be performed by receiving the bottom surface of the paper cup by the sharp projection portion of the mouthpiece, or the bottom outer circumference or the inner circumference of the paper cup. It may be received by the circumference of
Both of these may be used, but when receiving with sharp protrusions, it is necessary to appropriately adjust the number and shape of protrusions, the material strength of the paper cup, etc. so that the bottom surface is not pierced just by inserting the contents. There is. Also, the material of the mouthpiece can be plastic or metal, but manufacturability,
It is preferable to use plastic from the viewpoint of later disposal processing. The type of plastic material is not particularly limited, but suitable plastic materials include polypropylene, polycarbonate and impact-resistant styrene, nylon and the like.

In the present invention, after drinking the poured beverage, the bottom of the paper cup is incised at the same time that the bottom of the paper cup is incised by further pushing in the mouthpiece inserted into the bottom or rotating after pushing. Can be used as a megaphone as it is firmly pressed into the peripheral wall of the paper cup. In particular, the used paper cup is softened by the liquid content, which is convenient for press fitting and incision. Thus, the paper cup of the present invention can be used as a megaphone after use by a very simple operation, and is particularly suitable for watching a baseball game.

In the present invention, the mouthpiece is inserted into the bottom of the cup to be integrated, but it goes without saying that the mouthpiece may be separately sold.

Embodiment Hereinafter, the present invention will be described in more detail with reference to an embodiment with reference to the accompanying drawings.

Embodiment 1 FIG. 1 is a sectional view showing a first embodiment of the present invention.
The paper cup 1 is an ordinary paper cup, and the bottom surface is sealed by a known method to a trumpet-shaped peripheral wall. As shown in FIG. 1, the mouthpiece 2 has an annular outer peripheral portion and an annular continuous sharp projection portion having a plurality of sharp points inside thereof, so that the bottom portion of the paper cup 1 is inserted between them. It is installed. As can be seen from FIG. 1, in a normal state, the bottom surface of the paper cup 1 is received by the sharp projection portion of the mouthpiece 2 and the outer periphery of the bottom portion of the paper cup 1 is received by the annular outer peripheral portion of the mouthpiece 2. 1 is supported by the mouthpiece 2. When the beverage is poured into the cup in this state, the cup is held in this state. Since the bottom surface of the mouthpiece 2 is flat, it can be placed on the table as it is. FIG. 2 is a perspective view showing only the mouthpiece 2 in the first embodiment.

FIG. 3 is a cross-sectional view showing a state where the paper cup according to the first embodiment has a megaphone shape. In the state of FIG. 1, when the mouthpiece 2 is pushed up in the direction of the arrow, the bottom of the paper cup 1 is pierced by the sharp protrusion and at the same time the mouthpiece 2 is firmly attached to the peripheral wall of the paper cup 1 and pierced. When the bottom surface is removed, the shape becomes as shown in FIG. In this state, as shown in FIG. 3, the mouthpiece can be put on the mouth and used as a megaphone.

Embodiment 2 FIG. 4 is a sectional view showing another embodiment of the present invention.
