JP2003040277A - Double-walled container for instant food and the like - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a double-walled container having a clear printability for generating an effect appealing against visual perception, preventing any stacked state, showing a superior thermal insulating effect, facilitating for its recycle as well as its incineration process and attaining a less-expensive state. SOLUTION: A barrel part cover 2 of cardboard having a printed display at its outer surface is fixed to an outer side of a barrel 5 of a container main body 1 formed into a cup-shape by foamed resin in such a way that it can be peeled off. When a plurality of containers are stacked up in a vertical direction, the barrel part cover 2 of the upper side double-walled container is easily pulled off from the inner surface of the container main body 1 of the lower side double-walled container because an outer surface having a print 8 easily slips, resulting in that the double-walled containers are prevented from being stacked to each other. The outer surface of the barrel part cover 21 made of cardboard is applied with a clear desired print 8 to enable a printing characteristic lacked in the container main body 1 to be accommodated. Since the container main body 1 has a superior thermal insulating characteristic, it can accommodate for a thermal insulating effect lacked in the barrel part cover 2. When the container is wasted, the container main body 1 and the barrel part cover 2 can be easily separated. A total weight of the barrel part cover 2 made of cardboard and easily ignited or processed for its recycle is made to be heavier than that o the container main body 1.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cup-shaped double container useful for containing instant foods, beverages and the like.

[0002]

2. Description of the Related Art Cup-shaped containers for instant food and beverages include containers made of expanded resin such as expanded polystyrene and containers made of paper.

[0003]

The container made of foamed resin is excellent in heat insulating property, but when printed directly on the outer surface of this container, the printing becomes unclear. Also,
In the case of containers made of foamed resin, many containers of the same size are stacked in an empty state, and one container is automatically taken out from this stacked container group and filled with food. There is also a disadvantageous problem that stacking (or blocking) occurs in which two containers are in close contact with each other and are difficult to separate from each other, and two containers may be picked up at one time. on the other hand,
Paper containers have a clear and visually appealing effect (visual effect) when printed on the outer surface, and while they are recyclable and easy to incinerate, they do not have a sufficient heat insulating effect and therefore have a heat insulating effect. There is a problem in that the cost increases if a double structure is used to increase the cost.

The present invention has been made in order to solve such problems all at once, and an object of the present invention is to provide a visual effect that makes printing clear and visually appeals, and prevents stacking, and (EN) It is intended to provide a double container for instant foods and the like which has an excellent heat insulating effect. Another object of the present invention is to provide a double container for instant food or the like that can be recycled (re-commercialized), can be incinerated easily, and can be inexpensive.

[0005]

A double container for instant foods and the like according to the present invention comprises a container body made of a foamed resin molded in a cup shape and a print indication on the outer surface thereof, and a body portion of the container body. Of a paperboard body cover body that is detachably attached over the entire outer surface of the body cover body, and the total weight of the body body cover body is larger than the total weight of the container body. is there. In this case, the body cover body may be provided with both the knob portion and the parting line, or one of them.

[0006]

When a plurality of double containers of the same size having the above structure are stacked vertically, the inner surface of the container body of the lower double container and the body cover body of the upper double container overlap each other. Since the printed outer surface of the body is slippery due to the printing ink layer, the upper double container is easy to pull out from the inner surface of the container body of the lower double container, so stacking occurs when filling products. Can be prevented and the problem of taking two pieces can be solved.

Further, since the body cover body on which desired product indications, patterns, colors and the like are printed is made of paperboard, clear printing is obtained, and printing characteristics lacking in the foamed resin container body. Can be supplemented with excellent printing characteristics and can be visually appealing. Furthermore, since the container body made of foamed resin of the double container has excellent heat insulating properties, it is possible to supplement the heat insulating effect which is lacking in the body cover made of paperboard.

Furthermore, since the body cover made of paperboard is detachably attached to the outer side of the body of the container body made of foamed resin, the body cover made of paperboard is disposed at the time of disposal. Both can be easily separated by peeling them from each other, the body cover made of paperboard can be incinerated or recycled, and the container body made of foamed resin can be recycled. In this case, the total weight of the body cover, which is made of paperboard and is easy to incinerate or recycle, is larger than that of the container body made of foam resin, so the cost of incineration or recycling can be reduced. It will be possible.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a partially cutaway sectional view of a double container, FIG.
FIG. 4 is a cross-sectional view showing a stacked state of double containers.

As shown in FIG. 1, a double container according to the present invention has a cup-shaped container body 1 and a body part cover body 2 made of paperboard and attached to the entire outer surface of the container body 1.
Consists of. The container body 1 is made of foamed resin such as expanded polystyrene in a cup shape. In the embodiment shown in the drawings, the container body 1 is formed in a tapered cup shape in which the diameter of the bottom 4 is smaller than that of the upper opening 3. is there. The container body 1 of the illustrated example is formed into a taper-like cup shape having a circular bottom portion 4 and a body portion 5 which is erected upward from the entire circumference of the bottom portion 4. The flange portion 6 is formed so as to integrally project outward from the entire circumference of the upper edge of the opening of the body portion 5. The outer peripheral edge 61 of the flange 6 is formed in a shape bent downward. The lower end portion 51 of the body portion 5 is formed in a slightly narrowed shape with a step, and a step portion 7 protruding inward is annularly attached to the lower portion of the inner surface of the body portion 5.

On the other hand, the body cover 2 made of paperboard is printed on its outer surface, preferably the entire outer surface, with desired product markings, patterns, color designs, etc., and has a horizontally long fan shape in a developed state. To present. The body cover 2 is attached over the entire outer surface of the body 5 of the container body 1. In this case, the inner surface of the body cover 2 is scatteredly adhered to the outer surface of the body 5 of the container body 1. Either by bonding with an agent, or by joining the winding end edges 2a, 2c of the body cover body 2 between the overlapping surfaces with an adhesive, or by using the winding end edge 2a of the body cover body 2 or the upper and lower edges. Only one or more edges are attached with an adhesive for easy peeling. As means for attaching the body cover 2 to the body 5 of the container body 1, the unfolded body cover 2 may be wound around the entire outer surface of the body 5 of the container body 1 or may be previously covered. The body 2 is formed in a tapered cylindrical shape that fits the outer shape of the body 5, and a method of fitting this into the body 5 is adopted. In the illustrated example, the lower end edge 2b of the body cover body 2 is set to be located slightly above the outer bottom surface of the bottom portion 4 of the container body 1, but instead of this, the lower end edge 2b of the body cover body 2 is It is set to be flush with the outer bottom surface of the bottom portion 4 of the container body 1, or the lower end edge 2b of the body cover body 2 is set to a position slightly lower than the outer bottom surface of the bottom portion 4 of the container body 1. Is optional. Further, the total weight of the body cover 2 made of paperboard and the container body 1 made of foamed resin
When compared with that of, the total weight of the former, which is made of paperboard and is easy to incinerate and recycle, is set to be larger than that of the latter.

In order to make it easier to pinch the body cover 2 when the body cover 2 is peeled from the container body 1, as shown in FIG. 1, the lower end of the winding end edge 2a of the body cover 2 or the same figure. As shown by a chain double-dashed line, a knob portion 9 is provided at an appropriate position such as an upper portion or an upper and lower intermediate portion of the winding end edge 2a. By gripping the knob portion 9, the joint portion adhered between the overlapping surfaces of the winding end edge 2a and the winding start edge 2c of the body cover body 2 can be peeled off. The knob portion 9 may be provided in the shape of a tongue as shown in FIG. 1, or as shown in FIG. 3 or 4, two cuts 10 and 10 may be formed in the lower end edge 2b or the upper end edge of the body cover body 2. Forming the knob portion 9 between the notches 10 and 10 is optional. In this case, in order to make it easy to break the middle part of the body cover 2, a perforation line 11 such as perforations may be provided as shown in FIG. 3 or 4. At this time, it is preferable that the separating line 11 is provided so as to be linked to the knob part 9 so that the body cover body 2 can be broken along the separating line 11 by the action of picking and pulling the knob part 9.

The double container configured as described above is clear because printing is applied to the outer surface of the body cover 2 made of paperboard, and the outer appearance of the body cover 2 subjected to this printing is clear. Since the surface is slippery due to the printing ink, as shown in Fig. 2, stacking can be prevented even when a large number of the double containers are stacked in the empty state at the time of filling the products, and the double containers are separated one by one. It is taken out smoothly. In addition, for example, when this double container is used for a container for instant food such as instant ramen that is loosened with hot water, hot water is poured during edible use, but the container body 1 is made of a foamed resin having excellent heat insulating properties. The heat insulation effect of the container body 1 can reduce the heat transfer of the contents to the body cover body 2 made of paperboard, and the body body cover body 2 made of paperboard having insufficient heat insulation effect.
It is not hot and it is easy to hold by hand.

Further, as described above, a large number of the double containers are stacked vertically in a taper-fitted state as shown in FIG. Since the step portion 7 is attached to the lower part of the inner surface of the portion 5, the lower end edge 2b of the body cover body 2 of the upper double container comes into contact with the step portion 7 so that the upper double container moves downward. It is prevented that the taper fits deeper into the double container and is tightly fitted therein, and in this respect also, the above-mentioned one by one can be taken out more smoothly.

When the double container is used and then discarded, the body cover 2 is peeled from the body 5 of the container body 1 to easily separate the body cover 2 and the container body 1. The body cover 2 made of paperboard can be incinerated or recycled, and the container body 1 made of foamed resin can be recycled. In this case, since the total weight of the body cover 2 made of paperboard and easy to incinerate and recycle is larger than that of the container body 1 made of foamed resin, the incineration and recycling can be performed easily and at low cost. It can be carried out.

The container body 1 is not limited to a cup-shaped member having a circular cross-section, but a rectangular cross-section, a square cross-section, another polygonal cross-section, or an oval cross-section. The same can be applied to.
