FIG. 7 is an enlarged cross-sectional view showing a body portion of the in-mold label container.

  As shown in FIGS. 1 to 7, the in-mold label container 10 is a cylindrical container obtained by injecting an injection resin 5 onto the inner surface of the in-mold label 6. That is, the in-mold label container 10 includes a trunk portion 1, a flange portion 2 provided at the upper end of the trunk portion 1, a bottom portion 4 provided at the lower end of the trunk portion 1, and legs that are provided at the periphery of the bottom portion 4 and project downward. Part 3.

  Among these, the flange part 2, the bottom part 4, and the leg part 3 have the injection resin part 5 obtained by injecting injection resin in an injection mold (not shown).

  Moreover, the trunk | drum 1 has the injection resin part 5 which forms the inner peripheral surface of the trunk | drum 1 (inner peripheral surface side), and the in-mold label 6 which forms the outer peripheral surface of the trunk | drum 1 (outer peripheral surface side). Have. In addition, the leg part 3 may be an extension of the trunk part 1, and the in-mold label 6 may reach the leg part 3.

  Further, the injection resin portion 5 of the body portion 1 is provided with a horizontal rib 20 that protrudes inward from the inner peripheral surface of the body portion 1, and further, a stack rib 8 is provided below the horizontal rib 20. The horizontal rib 20 and the stack rib 8 will be described later.

  Next, the injection resin and the in-mold label 6 that form the injection resin portion 5 will be described.

  As a material of the injection resin that forms the injection resin portion 5, a synthetic resin such as polyethylene, polyethylene terephthalate, polystyrene, or polypropylene can be used.

  Next, the in-mold label 6 will be described with reference to FIG. As shown in FIG. 2, the in-mold label 6 has a fan shape, and the upper and lower corners of both end portions 6a and 6b of the in-mold label 6 are chamfered with a small R shape.

  As shown in FIG. 1, the length of the label 6 in the height direction preferably protrudes slightly to the flange portion 2 above the trunk portion 1 and reaches about the middle portion of the leg portion 3 below. As shown in FIGS. 3 and 6, the in-mold label 6 has a circumferential length of a gap 6 </ b> A having a width of about 0.2 to 2.0 mm between both end portions 6 a and 6 b that are abutted. It is preferable that the length is as long as it occurs. By forming such an in-mold label 6, the in-mold label 6 is inserted into a predetermined position of a female mold of an injection mold (not shown), fixed by vacuum suction, and after closing the mold, the injection resin 5 is inserted into the female mold. When injected from the gate at the center of the bottom, the injection resin 5 is smoothly injected without causing defects such as overlapping, turning and wrinkling on the in-mold label 6, and the in-mold label 6 and the injection resin 5 are separated. Can be integrated and molded.

  Such an in-mold label 6 may be composed of a single layer or two layers, but is often composed of three layers for providing a gas barrier layer or a printed layer. In the configuration for imparting barrier properties, the laminate is formed of a laminated sheet including at least a gas barrier layer. However, in order to improve the design properties, a printing layer such as a pattern or characters can be provided in part. A typical configuration example of the laminated sheet used for the in-mold label 6 includes the following configuration.

(1) (Outside) Stretched polypropylene film (thickness 30 μm) ・ Printed layer / adhesive / stretched polyethylene terephthalate film (thickness 12 μm) ・ Aluminum deposited layer / adhesive / stretched polypropylene film (thickness 30 μm)
(2) (Outside) Stretched polypropylene film (thickness 30 μm) ・ Printed layer / adhesive / stretched polyethylene terephthalate film (thickness 12 μm) ・ Deposition layer of inorganic oxide / adhesive / stretched polypropylene film (thickness 30 μm) )
(3) (Outside) Stretched polypropylene film (thickness 30 μm) ・ Print layer / adhesive / aluminum foil (thickness 7 μm) / adhesive / unstretched polypropylene film (thickness 30 μm)
In addition to the above, various configurations can be adopted. The in-mold label 6 is preferably free from curling as much as possible in terms of improving the yield during container molding. For this purpose, a film (a film of the same material) having a similar thermal shrinkage rate is laminated on both sides of the intermediate layer. In addition, it is preferable that the both sides be symmetrical with respect to the intermediate layer. Moreover, the thickness of each film shows an example and can be appropriately set depending on the dimensions of the container.

  In the laminated structure of (1) to (3) constituting the in-mold label 6, the inner film is a film that is bonded to the injection resin 5, and therefore preferably made of the same material as the injection resin 5. The gas barrier layer is an aluminum, aluminum vapor deposition layer, or an inorganic oxide vapor deposition layer. In the case of vapor deposition, a stretched polyethylene terephthalate film (thickness 12 μm) is used as the vapor deposition substrate, and aluminum or a transparent inorganic oxide is formed on the surface thereof. A vapor deposition layer is formed.

  As described above, alumina, silica, zinc oxide, magnesium oxide, ITO and the like can be used as the inorganic oxide vapor deposition layer constituting the in-mold label 6, and these can be used for vapor deposition, sputtering, ion plating and the like. By means, it is possible to form a vapor-deposited layer of inorganic oxide by depositing it to a thickness of about 200 to 1000 mm.

  Such an inorganic oxide vapor-deposited layer may be formed as a single layer, but by forming it as a plurality of layers, a more excellent gas barrier property can be obtained. Further, these inorganic oxide vapor-deposited layers are improved in adhesion, or in order to effectively exhibit excellent gas barrier properties by preventing damage such as cracks, on the upper and lower surfaces thereof, Reactive acrylic resin, polyurethane resin, acrylic resin containing silane coupling agent, water-soluble polymer containing metal alkoxide, ethylene-vinyl alcohol for the purpose of protective layer, gas barrier property improving layer, etc. A gas barrier layer can be formed as a composite layer by providing a resin layer such as a copolymer.

  In the configuration of the laminated sheet constituting the in-mold label 6, the adhesive between the films needs to have heat resistance because heat is applied together with the injection pressure of the polypropylene resin when the in-mold label 6 is molded in-mold. From this point, it is preferable to use a one-component or two-component reaction type polyurethane-based or acrylic-based adhesive and bond them by a dry laminating method.

  For example, a two-component reaction type polyurethane-based adhesive is mainly composed of a polyol component having a hydroxyl group at a polymer terminal and a polyisocyanate component having an isocyanate group, and a urethane bond is formed by a reaction between the hydroxyl group and the isocyanate group to be cured. Is.

  As a polyol component of such a two-component reaction type polyurethane adhesive, polyester polyol, polyester polyurethane polyol, polyether polyurethane polyol, or the like can be used. Polyisocyanate components include tolylene diisocyanate, diphenylmethane diisocyanate, hexamethylene diisocyanate, isophorone diisocyanate, tris (isocyanate phenyl), methane-tris (isocyanate phenyl) thiophosphate, tolylene diisocyanate, hexamethylene diisocyanate. For example, a urethane prepolymer obtained by adding an isocyanate monomer to trimethylolpropane, an isocyanate-modified product such as hexamethylene diisocyanate burette, hexamethylene diisocyanate, and isophorone diisocyanate trimer can be used.

  As a one-component reactive polyurethane adhesive, a prepolymer polyurethane adhesive having an isocyanate group at the end, for example, polyether polyurethane polyisocyanate obtained by reacting polyether polyol and diisocyanate, or reacting polyester polyol and diisocyanate is reacted. The polyester polyurethane polyisocyanate obtained by making it possible to use can be used.
