DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cup holder mainly mounted on the outside of a paper or plastic cup, and more particularly to a cup holder having excellent heat insulating properties.

[0002]

2. Description of the Related Art Drink cups handled by vending machines and stores are available for cold drinks and hot drinks, and are made of paraffin wax-coated paper or polyethylene, etc. Nowadays, it is widely spread with the increase in numbers.

[0003] Normally, beverage cups are intended to be simple disposable containers, so their heat insulation performance is not sufficient as compared with cup-men containers and the like, and a paper cup containing hot coffee or the like is held in hand. It is extremely difficult to keep it, and in the case of a polyethylene cup, for example, there is a danger that heat is transmitted almost directly, which may cause even a burn. Most people cannot tolerate the heat and must use their fingers to pinch the edge of the upper opening of the cup with their fingers to avoid spilling the beverage in them.

[0004] In addition, in the case of beverage cups such as cold juice, the outer wall (outer peripheral surface) of the cup body often gets wet due to dew condensation, and the hand holding the cup gets wet or slips, which is very uncomfortable for the user. There are cases.

[0005] In view of the above, various proposals have been made for using a cup holder separate from a beverage cup so that the beverage cup can be gripped safely and without discomfort. For example, as disclosed in Japanese Patent Application Laid-Open No. 9-154697, cuts are provided at both ends in the longitudinal direction of an arcuate strip-shaped cardboard, and the cuts are engaged with each other and locked to form a tapered end-open paper cylinder. An assembling paper cup holder having an end locking structure without a gripping portion is known.

[0006]

However, in the above-mentioned conventional cup holder, in order to enhance the heat insulating property, the thickness of the strip-shaped corrugated cardboard must be increased to some extent, and the flexibility is impaired. Mounting work becomes difficult, and conversely, if thin corrugated cardboard is used to obtain a certain degree of flexibility, there is a problem that sufficient heat insulating properties cannot be obtained.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a cup holder having excellent heat insulating performance even if it is thin enough not to lose flexibility.

[0008]

SUMMARY OF THE INVENTION A cup holder according to the present invention comprises a corrugated cardboard formed by superposing a corrugated paper sheet of a predetermined length and a flat paper sheet, and a heat insulating ceramic is formed on the surface of the flat paper sheet. It is characterized by being coated.

According to the present invention, since the heat insulating ceramic is coated on the surface of the band-shaped flat paper, the heat insulating property is higher than that of the uncoated cardboard.
For this reason, even if the thickness of the cardboard is reduced to some extent in order to secure flexibility, a sufficient heat insulating function is exhibited. This facilitates the work of attaching the cup to the cup, and at the same time allows the cup to be gripped safely and without discomfort.

The strip-shaped corrugated cardboard may be one in which both ends in the longitudinal direction are adhered and one opening is formed in a tubular shape wider than the other opening, or may be an assembling type as described later. In the former case, if the belt-shaped corrugated paper is arranged inside, a higher heat insulating effect is exhibited.

In the case of the assembling type, for example, a first cut portion cut from one side in the short direction is formed at one end in the longitudinal direction of the strip-shaped corrugated cardboard.
At the other end in the longitudinal direction, a second cut portion cut from the other side in the short direction is formed, and the first and second cut portions are engaged with each other so that both ends are engaged. What is necessary is just to comprise the joining part joined.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a view showing a cup holder according to a first embodiment of the present invention. This cup holder 1 is formed into a cylindrical shape as a whole by joining longitudinal end portions 5 of a strip-shaped corrugated cardboard 4 formed by superposing a strip-shaped corrugated paper 2 of a predetermined length and a strip-shaped flat paper 3 with an adhesive or the like. It is a thing. The cup holder 1 has its upper opening 7 formed to have a larger diameter than the lower opening 8, facilitating insertion of a not-shown cup accommodated inside from above and matching the taper of the outer peripheral surface of the cup. And keep the cup stable.

In this example, the corrugated paper 2 is a flat paper 3.
The surface in contact with the cup of the inner band-shaped flat paper 3 is coated with a heat insulating ceramic. If the thickness of the coating is too large, the cost is increased and the flexibility is impaired. If the thickness is too small, a sufficient heat insulating effect cannot be obtained. Therefore, the thickness is set to 1 μm to 500 μm, preferably 10 μm to 100 μm.

With such a configuration, the strip-shaped cardboard 4
Since the surface of the band-shaped flat paper 3 is coated with a heat insulating ceramic coating, it is possible to obtain a higher heat insulating effect than before. FIG. 2 shows the effect, using the product A with the heat insulating ceramic coating and the conventional product B without the coating, at 65 ° C. and 9 ° C.
Hot water at 0 ° C. was poured into each cup, and how the temperature of the cup holder surface changed with the lapse of time was measured. As is clear from this figure, the product A of the present example is superior to the conventional product B in heat insulation performance.
Therefore, the thickness of the cardboard 4 can be reduced accordingly. As a result, it is possible to reduce the material cost and the transportation cost, and to improve the workability at the time of attachment to the cup.

FIG. 3 shows a cup holder according to a second embodiment of the present invention. The cup holder 11 is formed by winding a band-shaped corrugated cardboard 4 of a predetermined length so that the band-shaped corrugated paper 2 is located inside the tube, and joining both ends 5 in the longitudinal direction with an adhesive or the like. Also in this case, the upper opening 7 of the cup holder 11 is formed so as to be wider than the lower opening 8, and the inner wall surface of the cup holder 11 is in close contact with the outer wall surface of a tapered beverage cup or the like. Made in.

According to this embodiment, since the band-shaped corrugated paper 2 is arranged inside the cylindrical cup holder 11,
The uneven shape of the band-shaped corrugated paper 2 forms a space between the outer wall of the beverage cup having a tapered structure and the inner wall of the cup holder 11, and exhibits an excellent heat insulating effect. Further, the band-shaped flat paper 3 is arranged on the outer wall of the cup holder 11 and a large area of the portion in contact with the palm can be secured, so that the user feels more secure when holding the cup. It is possible to obtain a feeling of use as if directly holding a drinking paper cup having a more tapered structure than using the holder 1. Further, in this embodiment, since the band-shaped flat paper 3 is disposed on the outside, characters and figures such as advertisements can be printed on the surface thereof, and can be used as a kind of advertising medium in a coffee stand or the like where many people come and go. Can also be used.

The cup holder 11 shown in FIG. 3 maintains a cylindrical state by joining the both ends 5 in the longitudinal direction with the joining portions 6.
By forming the perforated cut 9 at a position that is 90 ° out of phase with the connecting portion 6, the cup holder 11 can be bent at the cut 9 and easily folded. For this reason, it is easy to stack on a counter of a coffee stand or the like, and it is possible to carry it easily even when going out a little.

FIG. 4 shows a third embodiment of the present invention. The cup holder 21 of this embodiment is of an assembling type. The strip-shaped corrugated cardboard 4 is formed in a rectangular shape as shown in the developed views of FIGS. The strip-shaped corrugated cardboard 4 has cut portions 12 at both ends 5 in the longitudinal direction. The cut portions 12 at both ends are cut in different directions from different sides in the short direction. Each cut portion 12 includes a cut portion 13 formed in the shape of a blade of a cutter and a stop portion 14 for hooking the cuts to each other to assemble the cardboard 4 into a cylindrical shape.

The feature of the cup holder 21 is that, unlike the cup holders 1 and 11 shown in FIGS. 1 and 3 in which the shape of the finished product is tapered, the cut portion 13 in the coupling portion 6 is provided.
Of the corrugated cardboard 4 with the tip 15 of the acute angle portion
Since the overlapped portions of both ends 5 in the longitudinal direction slide in the surface direction, both openings of the cup holder 21 expand and contract in the radial direction. Thereby, since it can be used for the drink cup 10 of a taper structure of various sizes, the use range of a cup holder can be expanded remarkably. Further, according to this embodiment, it is not necessary to cut the corrugated cardboard into an arc shape as shown in FIG.
There is an advantage that production is simple and useless materials and the like are hardly produced in the manufacturing process.

As another embodiment having the same function, a rectangular band-shaped corrugated cardboard 4 in which a hook-shaped cut portion 18 is formed at both ends 5 as shown in FIG. Can be Of course, the effect of the present invention can be obtained by simply winding the strip-shaped corrugated cardboard 4 cut into the bow shape shown in FIG. 7 and coated with the heat-insulating ceramic coating around the cup. Further, the cup holder of the present invention can simultaneously improve excellent heat insulating performance and antibacterial property by employing antibacterial ceramic coated paper as the heat insulating ceramic coated paper.
