Description

  The present invention relates to a laminated material for a laminated tube container. More specifically, the present invention relates to a laminated material for a laminated tube container that is excellent not only in appearance, such as cosmetics, decorativeness, and design, but also in barrier properties against oxygen gas, water vapor, etc., and resistance to physical properties.

  Conventionally, a laminated material in which at least a surface resin layer, an intermediate layer, and an inner surface resin layer are sequentially laminated is used for a laminated tube container. And the cylindrical trunk | drum is manufactured by using the laminated material, superimposing the surface of the surface resin layer of the both ends of the laminated material, and the inner surface resin layer, and heat-seal the opposing surface. .

  Next, a head composed of a mouth, a shoulder and the like is formed in one opening of the cylindrical body, and a cap is screwed onto the head. On the other hand, the stored product is filled from the other opening of the cylindrical body, and then the opening is hermetically sealed to form a bottom seal to produce a packaged product made of a laminated tube container. is doing.

In the laminated tube container, the resin forming the surface resin layer constituting the laminated tube container is generally made of a polyethylene resin. Also, in a laminated tube container, a printed pattern layer is usually formed on the outer peripheral surface of the body portion, along with a desired pattern and displaying predetermined items such as product name, manufacturer, seller, date of manufacture, etc. ing.

  And the above-mentioned printed picture layer is generally a gravure printing method or the like in advance on the back surface of the resin film forming the surface resin layer constituting the laminated tube container or the original film of the resin film forming the intermediate layer, etc. To form a printed layer.

  After forming the printing layer, the laminate layer container is manufactured by laminating the materials constituting the intermediate layer, the inner surface resin layer, and the like as described above, and then using the laminate material. Is manufacturing.

  With the widespread use of laminated tube containers, consumers have come to use many similar shaped tube containers in their daily lives. For this reason, there are many demands and proposals for differentiation, identification, and the like of cosmetic properties, decorative properties, design properties, functionality, and the like for laminated tube containers.

  For example, a tube container (see, for example, Patent Document 1) that is advantageous for improving the feel and texture and distinguishing from other tube containers is known.

  This tube container is composed of a main body portion that is filled with contents and a head that is integrally connected to the main body portion and has a discharge port that discharges the contents filled in the main body portion. And the synthetic paper layer by which the embossing was given to the outer layer at least is provided in the main-body part of the tube container.

  There is also known a metal tube (see, for example, Patent Document 2) wrapped with a film that prevents leakage of stored items and that does not limit the display of characters and figures.

In this metal tube, a film is wound around the outer periphery of the metal tube container, and the initial position of application of the film is set to be at least 1 mm from the site end of the tube container and does not exceed 1/8 of the total outer peripheral length of the tube.

  A light-shielding tube container (see, for example, Patent Document 3) having excellent light-shielding properties without impairing the design of the container appearance is also known.

  This light-shielding tube container is made of at least two inner and outer resin materials, and at least one of the layers excluding the outer layer is colored in a dark color with high light-shielding properties.

Prior art documents are shown below.

  By the way, the tube container of patent document 1 is provided with the synthetic paper layer in the outer layer. The synthetic paper layer is embossed. For this reason, there is a problem that the glossiness is lost and the appearance is not good at the store.

  Furthermore, since the outer layer is embossed, there is a problem that dust or dirt is likely to enter into the groove portion or the like where the embossing is performed at a store or the like, and is difficult to remove.

  In addition, equipment such as an embosser (embossing machine) for embossing is required. And the work process increases. And there exists a problem which manufacturing cost rises.

Moreover, (b) is explanatory drawing which shows the relationship between the one base material laminated | stacked with the tape base material in Fig.5 (a), and the other base material.

  In the laminated material for the laminated tube container of the present invention, a plurality of tape base materials 5 are laminated between the base materials 11 and 12 to be laminated as shown in FIGS. The plurality of tape base materials 5 are the same as the one base material 11 and the other base material 12 between the layers in which the inner surface of one base material 11 and the outer surface of the other base material 12 travel by a drive roll or the like. Laminated with running at speed.

  As shown in FIG. 5 (b), the tape base material 5 depends on the surface condition of the lamination surface or the lamination method of one base material 11 and the other base material 12 on which a plurality of tape base materials 5 are laminated between layers. An adhesive material 14, a hot melt material, a heat sensitive material, a heat seal material, or the like is provided on one side surface or both side surfaces of the tape substrate 5.

  Next, FIG. 6A is a perspective view for explaining an outline of an embodiment in which the tape base material of the laminated material for the laminated tube container of the present invention is inserted into another base material. Moreover, (b) is explanatory drawing which shows the relationship between the one base material laminated | stacked with the tape base material in Fig.6 (a), and the other base material.

  The laminated material for the laminated tube container of the present invention is obtained by inserting a plurality of tape base materials 5 into the other base material 12 of the base materials 11 and 12 to be laminated as shown in FIGS. 6 (a) and 6 (b). Although not shown in the drawing, the other base material 12 is laminated on the inner surface of the other base material 12 in which 5 is inserted.

  The plurality of tape base materials 5 are the same as the one base material 11 and the other base material 12 between the layers in which the inner surface of one base material 11 and the outer surface of the other base material 12 travel by a drive roll or the like. Drive at speed. Further, the other base material 12 into which the plurality of tape base materials 5 are inserted enters the drive roll at the same position in the width direction in which the plurality of tape base materials 5 are traveling, and the same width as the width of the tape base material 5. Slit processing 9 is performed immediately before.

  Further, the other base material 12 to which the slit processing 9 is applied has the same width as the plurality of tape base materials 5, and the other base material 12 has a plurality of scums (slit scraps) on the rear side in the rotational direction of the drive roll. Discharge downward. Then, as shown in FIG. 6B, the plurality of tape base materials 5 are inserted into the other base material 12.

  Further, after the plurality of tape base materials 5 are inserted into the other base material 12, although not shown in the drawing, the inner surface of the other base material 12 into which the plurality of tape base materials 5 are inserted, Another substrate is laminated.

  The laminated material for a laminated tube container of the present invention is an excellent invention that can be applied to production lines in the confectionery and bakery fields as well as being excellent as a laminated material for laminated tube containers.
