Abstract

[PROBLEMS] To easily change the shape, to have a handle, to engrave sculptures to enhance the appearance, to express irregularities expressing Braille in a tube container, and to further improve the suitability of containers and contents peculiar to multilayers Provide a mold-concave-shaped tube. In a tube that is used by extruding a filled content, a concave-convex mechanism or Braille 2 representing information about the content is provided at any part from the shoulder portion to the lower end portion of the tube.

Description

  The present invention relates to a tube that can be mass-produced in addition to a handle and a sculpture that enhances the appearance, as well as an unevenness that represents Braille in a tube container.

The present invention relates to a tube having improved barrier performance against contents.

  Although the conventional cylindrical tube shown in FIG. 4 is a multi-layer tube, it has a cylindrical shape as indicated by 12 and a single resin having a separate part from the shoulder other than the main body indicated by 11. It consists of

  In the present invention, in view of the conventional problems as described above, the shape of the body is complicated, and a multilayer structure (PP / PE / Evr / nylon / PET is selected from the shoulder to the mouth, and each layer is set to 0.00. Improved barrier performance such as confidentiality and chemical resistance by composite resin by combining multiple layers at 1 mm to 0.3 mm to 0.5 mm).

  It is possible to express the shape in consideration of the improvement of decoration, Braille, shape along the handle and ease of drawing.

  The present invention has a multilayer structure from the shoulder to the mouth as shown in FIG. 1, the confidentiality by the composite resin, the improvement in chemical resistance, and the tube to be used by extruding the filling contents in any part from the shoulder to the lower end of the tube. Multi-layered concavo-convex shape characterized by providing a concave / convex mechanism such as 1 representing information about the contents or Braille like 2 and shapes such as constrictions and dents 3 for improving ease of holding and pushing It is a tube.

By expressing from the tube mouth part to the main body by multilayer molding, the barrier property including the mouth part is improved. In a tube that is used by extruding the filled contents, an uneven mechanism or Braille expression that represents information about the contents at any part from the shoulder portion to the lower end portion of the tube is also possible.
If the cut at the bottom is a body part, it can be mass-produced at a place where the length is not limited. As apparent from the above description, the present invention has the following effects.
(1) Based on multilayer blow molding technology, it can be molded consistently from the tube mouth to the body. Therefore, in the case of the multilayer specification, the barrier property including the mouth portion can be secured in order to improve the suitability of the contents.
(2) The shape of the multi-layer blow mold can be freely expressed by (1) above, improving the decoration, and making it easier for the blind to understand the shape and squeezing along the handle from the three-dimensional braille It is possible to express the shape in consideration of

  It is a figure of a multilayer type uneven | corrugated shaped tube about uneven | corrugated shape.   It is a figure which shape | molds a multilayer type uneven | corrugated shaped tube.   It is a figure explaining processing of the molded product of this case.   It is a figure of the conventional tube as a comparison object.

  Since it is not a conventional tube of extrusion molding, it is a molding method based on blow molding that can mass-produce various shapes. It can be realized from sculptures such as Braille to a design with a constriction like a handle instead of a cylindrical body. PP / PE / Evr / Nylon / PET resin materials are selected by a multi-layer molding machine, and each layer is combined in multiple layers at 0.1 mm, and a 0.3 mm to 0.5 mm resin is dripped by its own weight to set the shape. Molding is done by sandwiching in the mold and sending air. Thereafter, the set position is cut with a cutting machine, and the bottom part is crimped with a sealing machine to complete.

  Hereinafter, one embodiment will be described with reference to the accompanying drawing 2. FIG. 4 is a process diagram of the first embodiment of the present invention apparatus. In the raw material hopper shown in 4, PP, PE, Evr, nylon, and PET, which are resin raw materials, are selected and filled with respective raw materials. 7 is a diagram in which a mold having a shape set as shown in 7 is prepared for a resin in which the resin raw material is caused to flow down by its own weight, the mold is sandwiched as shown in 8, and air is sent to perform molding.

  Hereinafter, an embodiment will be described with reference to the attached drawing 3. It is a figure which completes by cut | disconnecting in a setting position with a cutting machine as shown to 9 with respect to the molded article after the shaping | molding of this case, and crimping | bonding a bottom part with a sealing machine as shown in 10. FIG.

The present invention is used in the industry for manufacturing (multi-layered rugged tube).

1: Concave and convex with emphasis on design.
2: Braille for the blind.
3: A constricted cylindrical shape that is not restricted and is easy to hold.
4: Raw material hopper.
5: Multilayer molding machine.
6: A multilayer resin that hangs down due to its own weight.
7: A mold having a set shape.
8: A mold that feeds air by sandwiching the sagging resin in a shape set.
9: A cutting machine that cuts the molded container at a set position.
10: Sealing machine for crimping the rear part.
11: Separate parts from the mouth of single resin molded from PP or PE to the shoulder.
12: A multilayer tube body having a cylindrical shape formed by extrusion molding.
