であった。2. Description of the Related Art Conventionally, a label for a packaging container for shampoo, conditioner, cosmetics, etc. has been pasted with a paper label on the main body of a packaging container made of resin. The paper label attached with glue does not pose a problem in normal home use, but has a problem that it is peeled off in a short period of time when used in a place with high humidity for 24 hours such as a hot spring bath. For this reason, it is possible to print directly on the main body of the packaging container made of resin, but there is a problem in that it lacks a sense of quality. In addition, multi-color printing tends to cause color misregistration. Therefore, in-mold molding has been performed in which the label formed of resin and the container body are integrally molded. In conventional in-mold molding, a label made of resin is fixed to a relatively flat part of the mold by vacuum suction or the like, and tubular molten resin (parison) is introduced into the mold and blow molding is performed to form a label and a container. Was integrally molded.

The illustrated in-mold molded product is a shampoo container 1 having a label 2 on at least a front surface thereof and a well-known hand pump 3 mounted on an upper portion thereof. The material of both the container 1 and the label 2 is polypropylene, which is a thermoplastic resin, and the label 2 is appropriately printed with UV ink. On the front surface of the container 1 and the label 2, a large number of thin kamaboko-shaped ridges 4 are juxtaposed in parallel with each other so that the central portion of the container 1 is longitudinally cut. It is the same. At the boundary between the label 2 and the container 1, as shown in FIG. 2, the tip of the ridge 4 of the container 1 is a pressing piece 5 that protrudes above the peripheral edge of the label 2. Hold down the section.

６に固定しても溝７ａに沿って変形することはない。Next, a method of molding the above-mentioned in-mold molded article will be described with reference to FIGS. 3 (a) to 3 (c) and 4 (a) to 4 (c). First, a concave-convex portion 7 for forming the convex stripe 4 of the container 1 and the label 2 is formed on the inner surface of the mold 6. As described above, since the ridge 4 is a kamaboko type, the uneven portion 7
Is a groove 7a having an inverted shape. The label 2 is fixed on the groove 7a of the mold 6 as shown in FIG. The groove 7 a is longer than the vertical dimension of the label 2 and extends over the surface of the container 1 and the label 2. Since the label 2 is made of polypropylene and is in a room temperature state, it is not deformed along the groove 7a even if it is fixed to the mold 6.

で覆われた以外の溝７ａの中に入り込む。Next, as shown in FIGS. 3 (b) and 4 (a), the heated tubular molten resin 8 made of polypropylene is introduced into the mold 6, and then the inside of the mold 6 is 5-7. Pressurize with air of about atmospheric pressure. Then, the tubular molten resin 8 swells and comes into close contact with the inner surface of the mold 6 and the back surface of the label 2. As shown in FIG. 4B, the tubular molten resin 8 adhered to the mold 6 has the label 2
It enters into the groove 7a other than the one covered with.

化すると上記した構成のインモールド成形品ができる。On the other hand, since the label 2 is softened by the heat of the tubular molten resin 8 and is deformed by the pressure and enters the groove 7a as shown in FIG. 3C, the timing of entering the groove 7a is the tubular molten resin. Late than 8. Therefore, until the label 2 is deformed, a gap S is formed between the label 2 and the groove 7a as shown in FIG. 4 (b), and thus the soft tubular molten resin 8 in the molten state causes the gap S between the label 2 and the groove 7a. Figure 4
As shown in (c), the pressing piece 5 is formed by sticking out on the label 2. In this state, when the temperature is lowered and the polypropylene is solidified, an in-mold molded product having the above-mentioned structure is obtained.

Therefore, in the bathhouse of the hot spring. Label 2 does not peel off even after long-term use.

り囲むことができる。In the embodiment described above, the concavo-convex portion 7 is formed in the groove 7a.
However, a small hemispherical protrusion may be used instead of the groove 7a. In such a case, dimples 9 are formed on the entire label 2 as shown in FIG. In the case of this embodiment, the dimples 9 are arranged at least at the peripheral portion of the label 2 so that the pressing piece 5 can be formed between the dimples 9. Further, the uneven portion 7 may be a hemispherical depression instead of the hemispherical protrusion. In this case, hemispherical projections are scattered throughout the label 2, and the projections arranged on the periphery of the label 2 serve as the pressing pieces 5. In addition, the above embodiment,
Although the pressing piece 5 is formed only partially, it may be arranged on the entire peripheral edge of the label 2 as a matter of course. Also,
As shown in FIGS. 6 and 7, the uneven portion 7 of the mold 6 is attached to the label 2
If the outer peripheral edge of the label 2 is slightly protruded into the outer peripheral edge 7b and blow molding is performed, the outer peripheral edge of the label 2 is completely surrounded by the pressing piece 5 as shown in FIG. be able to.

効果がある。The in-mold molded product of the present invention has the above-mentioned constitution, and the pressing piece molded so that a part of the molten resin is projected onto the peripheral portion of the label presses the end portion of the label. The label is difficult to peel off. Further, in the case where the concave-convex portion of the mold has a large number of grooves, a large number of rod-shaped pressing pieces along the shape of the groove press the end portion of the label, and the label and the container have a linear shape. Since the binding is stronger due to the unevenness, the label is more securely fixed. Also,
In the molding method of the in-mold molded article, when the tubular molten resin is pressed against the mold and the label, a part of the molten resin between the mold and the label is deformed before the label is deformed along the uneven portion of the mold. A pressing piece is formed such that the molten resin flows into the gap and a part of the molten resin is extruded onto the peripheral edge of the label, and the pressing piece is solidified to hold the edge of the label. Therefore, an in-mold molded product in which the label does not easily come off can be produced very easily. Further, in the case where the concave-convex portion of the mold has a large number of grooves, the molten resin flows smoothly along the grooves, so that the pressing piece can be reliably molded, and so on.
