Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a paper heat resistant cup container.

[0002]

[Prior art and its technical problem]

 Instant foods such as instant noodles and instant miso soup are stored in a disposable container in a dried state, and then they are eaten by pouring hot water. Styrofoam insulation containers are commonly used as containers for such foods, but paper cup containers are used because of the difficulty of causing waste pollution. However, since the paper cup container has poor heat insulation, conventionally, a handle member is attached to the outer periphery of the cup-shaped body, or a corrugated tubular body is fitted around the outer periphery of the cup-shaped body. Was adopted. However, in such a structure, in addition to the cup-shaped body, a separate member must be made, and a step of fixing it to the cup-shaped body by adhesion or the like is required. Therefore, there is a problem that the manufacturing cost becomes high.

The present invention was devised to solve the above-mentioned problems, and its purpose is to provide a heat-resistant cup container which has a simple structure and is made of paper and has good heat resistance. To provide.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention relates to a water-resistant paper cup-shaped container having a body and a bottom, which has a space between the body and the outer peripheral surface of the body and which has a sufficient height to be lowered and grasped by hand. The surrounding wall is formed integrally with the top edge of the body as the starting end. The heat-resistant cup container made of paper according to the present invention is suitable for containers such as instant noodles, instant miso soup, instant soup, and instant shiruko, as well as containers for hot water beverages such as coffee and cocoa sold by vending machines. is there.

【Example】

 1 and 2 show a first embodiment of a paper heat resistant cup container according to the present invention. Reference numeral 1 denotes a body and 2 denotes a bottom, which are made of a single-layer or multi-layer paper material having good water resistance and oil resistance. The body 1 preferably has a taper shape in which the diameter increases as it goes upward, and a folded-back portion 10 that is bent inward is formed at the lower end, and the flange portion 20 of the bottom 2 is formed between the folded-back portion 10 and the inner surface of the lower body. It is sandwiched.

Further, according to the present invention, a gripping outer wall 11 extending outward and downward from the top edge 12 of the body 1 is formed, and an outward curl portion 110 is formed at a lower end portion of the gripping outer wall 11. Are formed. The gripping outer wall 11 is not in contact with the body outer surface 13 and has a gap 3 for heat insulation between the outer wall 13 and the outer wall 11, and the outer wall 11 is preferably two fingers or more in width. Has a height H which is about 1/2 or more of the body height. In this embodiment, the diameter of the gripping outer wall 11 becomes wider toward the lower side.

FIG. 3 shows a second embodiment of the present invention. In this embodiment, an inward curl portion 110 ′ is formed at the lower end of the grip outer wall 11 and FIG. 4 is a fourth embodiment of the present invention. An example is shown, and a streak portion 111 is formed on the gripping outer wall 11. The streak portion 111 is in the horizontal direction in this example, but may be in the vertical direction or the oblique direction. Further, it may be a projection instead of a streak. In addition, in the embodiment, the gripping outer wall 11 has a downward opening taper shape, but the present invention is not limited to this, and may be a vertical downward shape. In addition, in the drawings, 4 is a lid attached to the top edge 12 of the body, 5 is a food and drink tool such as chopsticks, forks, and spoons, and 6 is food such as instant noodles.

[0008]

[Operation of the embodiment]

 As described above, the present invention has the gripping outer wall 11 that extends down from the top edge of the torso 1 and has the space 3 between the outer wall 11 for gripping and the outer peripheral surface of the body. As shown in FIGS. 1 and 4, the eating / drinking tool 5 can be mounted, and the eating / drinking tool 5 can be integrally set and sold or carried. Further, since the gripping outer wall 11 has a spring property due to the gap 3, it is possible to reduce the impact applied to the body 1 from the outside, and the food 6 can be safely stored. When eating foods such as instant noodles 6, hot water is poured into the body 1 and the gripping outer wall 11 is held by the hand A. Since the body 1 has no heat insulating property, it becomes very hot. Since the gripping outer wall 11 has a length of at least two fingers or more, the finger a does not directly touch the torso 1. Further, since the gripping outer wall 11 is only connected at the top edge of the trunk, the heat transfer area is small, and there is a gap 3 between the gripping outer wall 11 and the trunk outer peripheral surface 13, which functions as a heat insulating space. . In addition, the rigidity of the paper is lowered by pouring hot water, but the gripping outer wall 11 has a small amount of heat transfer so that sufficient rigidity is maintained and it is possible to eat while firmly gripping. Therefore, although it is made of paper, good heat insulation can be obtained, and food and drink can be stably eaten.

In the first embodiment, since the outward curl portion 110 is provided at the lower end of the grip outer wall 11, the hand becomes difficult to slip when the grip outer wall 11 is gripped. In the second embodiment, since the inward curl 110 'is provided, the stacked state is maintained well, and when the external force is applied to the gripping outer wall 11, the gap 3 between the outer peripheral surface 13 and the body outer surface 13 is maintained. It can be held securely. Further, the holding of the food and drink 5 is also ensured. According to the third embodiment, since the gripping outer wall 11 has the ridge portion 111, the rigidity of the gripping outer wall 11 is increased by the rib effect, the slip can be prevented, and the heat radiation area is widened. The heat insulation is also improved.

To obtain the paper heat-resistant cup container according to the present invention, for example, as shown in FIG. 5, a gripping outer wall portion 10 ′ having a length H ₂ is attached to a body portion 1 ′ having a predetermined length H _1. Prepare a fan-shaped blank B with the added dimensions. It is preferable that the blank B is directly printed with an advertisement, a product description, or the like, or a printed cover C is attached to the inner surface of the gripping outer wall portion 10 '. Then, as shown in FIG. 6, the body 1 is roll-formed and the bottom 2 is assembled according to a conventional method, and then the gripping outer wall portion 10 'is inverted and bent at the top line of the body portion 1', and the lower end portion is bent. A curl portion may be formed on the. Alternatively, at the stage of the blank B, it may be inverted and bent with the top line of the body portion 1'as a boundary, and the roll molding may be performed in that state. In any case, the present invention does not require any other member and can be manufactured by the cup molding process.

[0011]

[Effect of device]

 According to the present invention described above, it is possible to provide good heat insulation without using any other member even though it is made of paper, has a simple structure, and does not require the process of manufacturing and assembling the other member, so that it is inexpensive. Excellent effects such as being able to be manufactured can be obtained.
