Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a double container having a container body made of different materials.

[0002]

[Prior art]

 For a container into which hot water is poured, such as coffee or cup ramen, it is preferable that the container can maintain a certain shape even when the hot water is poured, in order to prevent the poured hot water from easily spilling. From this point of view, paper cups and heat-resistant synthetic resins are often used as containers.

On the other hand, when this type of container is held with bare hands, the heat of the contents is transferred to the hand as it is, which is inconvenient. Therefore, a double container has been proposed in which the container has a double structure of, for example, a synthetic resin and paper, and the heat conductivity from the contents to the outside is suppressed.

By the way, in this type of double container, it is desirable that the double structure has good adhesion at the time of use, that is, at the time of eating and drinking, and therefore, the first container body and the second container body are manufactured by the following manufacturing procedure. I was trying to improve the adhesion with.

That is, in a state where a second container body made of a paper body is set in one die in advance, the other die is aligned, and a mold formed between the paper body and the other die is formed. A double container was manufactured by injecting resin into the space and in-molding the first container body.

In addition to the in-mold molding, it is also possible to use an adhesive to bond the first container body and the second container body to enhance their bondability. According to these methods, the adhesion between the second container body and the first container body can be enhanced, and even when the materials of the two container bodies are different, one container body is used during use (at the time of eating and drinking). It never fell out.

[0007]

[Problems to be solved by the device]

 However, the double container in which the intimate contact between the container bodies is improved by the in-mold molding or the adhesive as described above is convenient for use, but has the following problems at the time of disposal.

That is, in recent years, from the viewpoint of global-scale environmental pollution, waste of resources, etc., there is an opinion that household waste should be sorted and collected according to the type and material of waste, and that recyclable materials should be reused. It is rising. In fact, some local governments have already begun collecting waste by separating synthetic resin waste into styrofoam-based waste and hard plastic-based waste.

Under such circumstances, the conventional double container has been considered only for convenience during use (at the time of eating and drinking) as described above. For example, when a consumer disposes of this container after using the double container (after eating and drinking), may the consumer first dispose of it as paper dust that constitutes one container body, or the other container? It is conceivable that it may be discarded as plastic waste that constitutes the container.

Next, even if one notices that it is necessary to separate the containers into separate containers and dispose of them, it is difficult to separate the containers due to the high adhesion between the containers as described above. It is possible that it will end up.

For this reason, this type of double container was eventually forced to be discarded as an integral structure. The present invention has been made in view of this point, and provides a separable double container for each container body according to the recent waste collection form.

[0012]

[Means for Solving the Problems]

 The present invention relates to a double container, in which a bottom 3 and a side 4 form a content-accommodating space 5 and a first container 1 and at least a side 4 of the first container 1. The second container body 2 is made of a material different from that of the first container body 1 and is provided with the peelable portion 6 at least partially.

[0013]

[Action]

 By peeling the second container body 2 from the peelable portion 6 after the use of the container, the first container body 1 and the second container body 2 can be separated from each other. It is possible to dispose the container body 1 as plastic waste and the second container body 2 as paper waste.

The peelable portion 6 is realized by providing, for example, a perforation 7, a notch, a notch or the like in a part of the second container body 2. Of course, the peelable portions 6 may be inconspicuous from the outside, but more preferably, the perforations 7 or the notches or the like can be easily grasped from the outside. The purchaser can be made aware that this double container is separable, and the effect of separate collection can be enhanced.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows an example of the double container of the present invention, in which the first container body 1 is made of synthetic resin and the second container body 2 is made of a paper cylinder.

The first container body 1 has a bottom portion 3 and a tubular side portion 4 that form a content storage space 5, and the top surface thereof is open. At the edge of this opening, there is a flange 8 that projects slightly horizontally outwards over the entire circumference. The side portion 4 is formed in a tapered shape whose diameter decreases from the upper portion of the opening to the bottom portion 3.

The second container body 2 has a cylindrical shape that covers the outer peripheral surface of the side portion 4 of the first container body 1, and the cylindrical shape is on the side of the first container body 1. It has a tapered shape corresponding to the portion 4.

As shown in FIG. 2, the upper end portion of the second container body 2 is in contact with the flange 8 of the first container body 1, and the lower end portion is lower than the bottom portion 3 of the first container body 1. Also forms the sleeve portion 10 extending further downward. That is, even when hot water is poured into the double container by the sleeve portion 10, the heat of the contents is not transferred to the container mounting surface due to the space formed by the bottom portion 3 and the sleeve portion 10. .

Two perforations 7, 7 are provided above a part of the lower end of the second container body 2, and a portion surrounded by the perforations 7, 7 is configured as a peelable portion 6. Has been.

As shown in FIG. 1, the peelable portion 6 can be picked up from the lower end and a part of the second container body 2 can be peeled off from the side 4 surface of the first container body 1. At this time, in this embodiment, since the sleeve portion 10 is provided at the lower end of the second container body 2 as described above, by inserting a finger inside the sleeve portion 10 and pulling the finger outward, As shown in FIG. 1, the peelable portion 6 can be easily peeled off.

As described above, by peeling off the peelable portion 6, the other portion of the second container body 2 (the portion other than the peelable portion 6) can be peeled from the first container body 1 very easily. become.

Next, the manufacturing procedure of the double container of this embodiment will be briefly described with reference to FIG. First, the paper body (the second container body 2) having the perforations 7 formed thereon is preliminarily printed on the surface, assembled into a cylindrical shape, and set in the lower mold 11.

Next, the upper mold 12 is positioned with respect to the lower mold 11 while the second container body 2 is set in the lower mold 11. At this time, a mold space 13 is provided between the second container body 2 set in the lower mold 11 and the upper mold 12. A synthetic resin is injected under pressure into the mold space 13 to form the first container body 1. In this way, by in-molding the first container body 1 with the second container body 2 set in advance, the adhesion between the first container body 1 and the second container body 2 is enhanced. You can

The upper mold 12 and the lower mold 11 are opened in a state where the second container body 2 has dropped to a constant temperature, and the first container body 1 and the second container body 2 are integrated. The new double container is removed.

Since the double container thus obtained has good adhesion between the first container body 1 and the second container body 2 during use, both containers 1 and 2 separate and fall off. It can be easily separated by the peelable part 6 at the time of disposal.

The perforations 7, 7 as the peelable portion 6 are formed in a spiral shape on the peripheral surface of the second container body 2 as shown in FIG. Good. Further, instead of the perforations 7, 7, a notch 14 as shown in FIG. 5, or a notch or the like may be provided to form the peelable portion 6.
