なる。2. Description of the Related Art Conventionally, bottle-shaped containers made of plastic resin such as polyethylene and polypropylene by blow molding have been widely used. However, recently, from the viewpoint of environmental protection, there has been a demand for reduction of the amount of plastic resin used in these containers and separate collection. Therefore, in order to reduce the amount of plastic resin used, it is conceivable to reduce the thickness of the container, but in this case, the container is generally softened, which makes it difficult to stand by and to hold.

ー包装である。In order to avoid such problems, a container in which a thin plastic bottle is reinforced with a paper cylinder has been proposed. For example, in the one disclosed in Japanese Patent Publication No. 6-505949, a plastic bottle is provided with a substantially quadrangular concave portion which is inclined inward toward the inside of the container, and a flap is formed at the upper end of the paper cylinder. This is a plastic container packaging in which the bottle shoulder portion bulges outward to form a step while being engaged with the recess of the lever, thereby preventing the paper tube from slipping upward.

問題点がある。However, in the above-mentioned conventional example, the flap of the container is pressed against the wall of the recess by utilizing the fact that the recess of the container is formed so as to incline inward toward the container, and the engaging force is increased by the repulsive force. In particular, when the container is formed thin, there is a problem that the container is dented by a slight force, the flap easily comes off, and the paper cylinder easily comes off.

This preform is composed of a mouth portion and a tubular portion, and the body portion 4 and the bottom portion 5 of the bottle are formed by extending the tubular portion in the vertical and horizontal directions. Next, this preform was inserted into a blow mold, stretch-blown, and sufficiently stretched in the longitudinal and transverse directions to form a thin bottle 1. By using the injection stretch blow molding method as described above, the gas barrier property, the aroma retaining property, the strength, and the like are improved, so that the amount of resin used can be significantly reduced.

A plurality of groove portions 4a and flat portions 4b are alternately exposed in the lateral direction. Further, on both left and right side surfaces of the thin bottle 1, vertical grooves 9 are formed only on the flat portion 4b for facilitating the crushing. The vertical grooves 9 descend straight from the shoulder portion 3 and have a human-like shape at the lower end. Has branched to.

い。A vertical wall portion 5b is formed in a range of a length of 5 mm above the boundary line between the body portion 4 and the bottom portion 5, and the bottom portion 5 is formed in a tapered shape so that the body portion 4 and the bottom portion 5 are connected to each other. A slanted wall portion 5a is formed below the boundary line at 30 degrees.
Since it is important that the vertical wall portion 5b is in close contact with the paper tube, both of them correspond to each other. That is, the sliding contact wall portion of the present invention is not limited to the vertical wall portion 5b, but may be an inclined shape that is inclined toward the outside of the container,
It also includes a curved one, and a paper cylinder having a wall surface having a corresponding shape may be used.

And it was extremely thin. Conventional capacity 2000m
The amount of resin required for the 1-liter bottle was about 80 g, and the thickness of the body was 500 μm to 600 μm. It was possible to reduce the thickness to about 1/3 to 1/2.

The thin bottle 1 filled with the content liquid was inserted from the upper side of the paper tube 6 (see FIG. 2), which was attached to the inner surface of the point 7 at a point. At this time, the bottom portion 5 of the thin-walled bottle 1 is formed in a tapered shape, and below the boundary line between the body portion 4 and the bottom portion 5 is constituted by the inclined wall portion 5a having an angle of 30 degrees. The adhesive 8 smoothly passes through the paper cylinder 6 without adhering to the body portion 4 and the bottom portion 5.
Since the vertical wall portion 5b is formed over 5 mm above the boundary line between and, the vertical wall portion 5b is adhered while squeezing the raised portion of the hot-melt adhesive 8 to extend the adhesive area (see FIG. 1). ).

Further, the composite container 10 was held in the hand and inverted and repeatedly poured out little by little, but the thin-walled bottle 1 was not deformed to the end and the thin-walled bottle 1 could be used without coming out of the paper tube 6. After the use, when the thin-walled bottle 1 was pulled upward while the paper barrel 6 was strongly pressed down, the thin-walled bottle 1 and the paper barrel 6 were separated. When discarding, the paper tube 6 was folded flat and the body portion 3 of the thin bottle 1 was crushed by hand. Since the vertical groove 9 was formed, it could be crushed more easily than before. And paper cylinder 6 and thin bottle 1

The container body and the paper tube are integrated. Then, even if the remaining amount in the container body is reduced by the pouring and the container body is deformed, there is an effect that the container body does not come off from the paper tube. Further, since the heat-sensitive adhesive is applied to the paper cylinder instead of the container body, it is possible to prevent the thin-walled container body from being deformed by the adhesion of the heat-sensitive adhesive at high temperature. In addition, if the bottom of the container body is formed in a tapered shape and a range of 5 mm or more above the boundary line between the body and the bottom is constituted by the sliding contact wall portion that is in close contact with the paper tube, the container is placed in the paper tube. When the main body is inserted, the heat-sensitive adhesive is squeezed to expand the adhesion area. Further, if the lower part of the boundary between the body and the bottom of the container body is composed of the inclined wall part of 30 degrees or more and 70 degrees or less, the container body is placed inside the paper cylinder without the heat-sensitive adhesive adhering to the bottom part. Can be inserted into. Thus, the present invention is a practically excellent composite container.
