ならず、効率の悪いものとなつてしまつていた。(Prior art) The surface of a plastic container is marked with the contents,
It is common to provide a printed layer to display products, and labels are mainly used. When trying to obtain a labeled plastic container, the label is usually applied after the container is formed, which must be done in a separate process, and the adhesive used for the label may be a pressure-sensitive adhesive or a water-based adhesive. is used. Labels using pressure-sensitive adhesives require release paper on the back, which is expensive, and requires an operation to peel off the release paper before use, making them inefficient. It was closed.

着剤を塗布し、容器に接着しなければならず、同
様に効率の悪いものであつた。 On the other hand, when a water-based adhesive is used, the adhesive must be applied with a labeler and adhered to the container, which is similarly inefficient.
そこでプラスチツク容器の成形と同時にラベル
貼付をおこないラベル貼り工程を不用とするイン
モールドラベルシステムが提案されている。 Therefore, an in-mold label system has been proposed in which the label is attached at the same time as the plastic container is molded, thereby eliminating the need for a label attaching process.

跡が残りたいへん外観が悪くなつてしまう。(Problem to be solved by the invention) With in-mold labels, the label must be inserted and placed on the inner wall of the mold to correspond to the container label position.The first method of fixing the label is to use an electrostatic generator to There are two methods: one method is to charge the container label and fix it to the inner wall surface of the mold, and the other is to make a hole in the mold corresponding to the container label position and fix the label there by suctioning it with a vacuum pump or the like. The former has a weak label fixing force and is effective when the label base material is a film, but is not suitable for paper labels, which are generally widely used, because they are difficult to charge. Furthermore, in the case of containers such as polyester containers and polyvinyl chloride containers that are biaxially stretched and blow-molded, the label is displaced from its pre-fixed position due to the expanding resin when the preform is stretched and blown up. As a countermeasure, it is desirable to increase the number of label suction holes or increase the diameter to improve the label fixing force, but increasing the number of holes makes the mold more complicated and processing becomes difficult. Furthermore, if the diameter of the hole is increased, traces of the suction hole will remain on the label of the container, resulting in a very poor appearance.

用ブロー金型とした。(Means for Solving the Problems) The present invention has been made to solve the above problems, and is an in-mold label in which the label is inserted and fixed in advance into a blow mold and the label is pasted on the plastic container at the same time as the molding of the plastic container. A sintered metal with many fine through holes is embedded in the blow mold at the position corresponding to the label, and the label is suctioned and fixed to the inner wall of the mold, and the outer diameter of the sintered metal is 4 mm.
This blow mold for in-mold labels is characterized in that the through holes have a diameter of 0.1 mm to 0.5 mm, and at least one sintered metal is provided per 11 cm 2 of label area.

Since there is at least one label per cm2 , there is no problem with poor label fixing force when the label is placed on the corresponding position on the inner wall of the mold, or deviation due to resin pressure during molding, resulting in excellent label positioning accuracy. You can get a container.

つてしまう。 The blow mold 1 has three sintered metals 3 embedded in a position 2 corresponding to the label part of the container, and piping is connected inside the mold between each of the sintered metals 3 and a joint 4 at the top of the mold. It is connected at 5. Label suction can be performed by connecting this joint 4 to a vacuum source such as a vacuum pump using a hose or the like. Sintered metal 3
As shown in FIG. 2, the through-holes 6 have a large number of fine through-holes 6, and the through-holes 6 are formed in parallel straight lines and do not intersect inside the sintered metal. The sintered metal used in the present invention is made of Fe-Cu alloy or stainless steel, and must have an outer diameter of 4 mm or more and a through hole diameter of 0.1 mm or more and 0.5 mm or less. If the outer diameter of the sintered metal is smaller than 4 mm, the suction force per piece of sintered metal will be small due to pressure loss in the piping and through holes, making it impossible to obtain a satisfactory label fixing force. In addition, if the diameter of the through-hole is smaller than 0.1 mm, the through-hole is likely to become clogged with paper dust or molding resin from the paper label, and if it exceeds 0.5 mm, the mark of the through-hole will be transferred to the label, spoiling the appearance of the in-mold label container. . In addition, the quantity of sintered metal is at least one per 11cm2 of label area.If it is less than this, it will be fixed to the inner wall of the mold in containers such as polyester containers and polyvinyl chloride containers whose preforms are biaxially stretched and blow molded using high-pressure air. The label that is being placed will move due to the resin pressure, resulting in poor label positioning accuracy.

跡が残らず外観は良好であつた。 The blow mold of the present invention is shown in FIG. The container to be molded is a biaxially stretched blown polyester container, with a volume of 900 ml and a container weight of 40 g.The label is made of synthetic paper (manufactured by Yupo Oji Yuka), and a hot melt adhesive is attached to the back of the label. (ad coat
33DW1790 (manufactured by Toyo Morton) applied thickness
One with a diameter of 130 μm and a label area of 60 cm 2 was used. For sintered metal, outer diameter is 8 mm, through hole diameter is 0.5 mm,
As shown in FIG. 3, six of them are embedded in positions corresponding to the label portion, satisfying the structure of the present invention. In the method for manufacturing labeled containers, first, the label is inserted and placed in a position corresponding to the label portion of a blow mold, and at this time, the label is suctioned and fixed through a through hole in the sintered metal. A vacuum pump is used as the vacuum source for suction, and the vacuum level is 400 mmHg. After this, the preform heated to 100°C to 110°C is introduced and the mold is closed. Next, high-pressure air of 20 kg/cm 2 is blown into the preform from a blowing tube attached to the top of the preform to produce a labeled plastic container. In this container, the appearance was good, with no misalignment of the label or traces of sintered metal left on the label surface.
