Description

  The present invention relates to a decorative container.

Various cosmetic containers such as a compact container and a lipstick container that contain cosmetics are required not only to have functionality but also to have a design that is attractive and has a design that reflects a product image. For this reason, various techniques for decorating the cosmetic container and the like have been proposed. For example, the decoration which looks like an aurora tone or an opal tone is performed by applying a paint on the surface of a container main body or a lid constituting the cosmetic container (for example, see Patent Document 1).
JP-A-8-231900

  However, in recent years, various decorations have been applied to cosmetic containers and the like, and there is a problem that it is not possible to attract customers' eyes by simply decorating them in an aurora-like manner. In addition, there is a problem that the appearance of the paint deteriorates at an early stage due to deterioration of the paint over time, wear or damage. In addition, if the surface of the container body or the lid is smooth, there is a problem that the fingers are easily slipped and the container is easily dropped from the fingers.

  The present invention has been made in view of such circumstances, and its purpose is to provide a decorative container that is excellent in design, can maintain good appearance over a long period of time, and is difficult to drop from fingers. To do.

  In order to achieve the above object, the decorative container of the present invention is a container in which at least a part of the surface is formed of a resin molded body, and a prism-shaped uneven surface is formed on the surface of the resin molded body. A configuration is adopted in which a film material having an aurora-like color tone is disposed on the portion of the resin molded body corresponding to the prismatic uneven surface.

  That is, in the decorative container of the present invention, a prism-shaped uneven surface is formed on the surface of a resin molded body constituting at least a part of the surface, and the aurora is formed on the portion of the resin molded body corresponding to the prism-shaped uneven surface. A film material having a tonal color tone is disposed. Therefore, in the decorative container of the present invention, the film material allows an aurora-like optical color pattern to be seen on the container surface, and the prism-shaped uneven surface increases the brightness of the color pattern, resulting in a deep three-dimensional structure. The color pattern appears to be a completely different color pattern from that obtained by applying a paint to the surface of the container as in the conventional example, and is excellent in design. In addition, in the decorative container of the present invention, the above-mentioned film material and prism-like uneven surface are not deteriorated early, worn, or damaged, and can maintain good appearance over a long period of time. Moreover, the surface of the decorative container of the present invention has a rough surface where the prism-shaped uneven surface is formed, so that the fingers are difficult to slip and the container is difficult to drop from the fingers. And since the said film material consists of what laminated | stacked the several transparent film, intensity | strength is strong and can absorb this even if an impact etc. act on the surface of the decorating container of this invention at the time of conveyance, etc. it can.

  In the present invention, the “prism-like uneven surface” means a surface on which minute unevenness (surface roughness: 10-point average roughness of about 0.1 to 30 μm) is formed, and the prism effect is produced by the minute unevenness. ing. As the shape of the micro unevenness, there are a plurality of protrusions having a substantially triangular cross-sectional shape (one side is the bottom) arranged in parallel in a predetermined direction (see FIG. 3), and a groove having a substantially V-shaped cross-sectional shape in a predetermined direction. A large number of adjacent convex portions, such as a pyramid shape (for example, a quadrangular pyramid shape), a truncated pyramid shape (for example, a quadrangular pyramid shape), a conical shape, and a large number of convex portions of a truncated cone shape are aligned (for example, in a predetermined direction , Which are erected (see FIG. 7) and are wave-like in which concave and convex curved surfaces are alternately arranged in a predetermined direction, and are commercially available. Various types can be considered that can be formed by using a prism sheet and transferring the prism surface of the prism sheet to the surface of the container.

  Further, in the present invention, the “film material having an aurora-like color tone” means a multi-layer exhibiting an aurora-like color tone by structural color development using multiple increased reflection of specific wavelengths due to optical path difference interference (refractive index × thickness) of each layer It consists of a film material with a laminated structure, a film material (or a foil) that exhibits an aurora-like color tone by laminating a large number of transparent films having at least one of color and refractive index, and itself follows the shape of the container surface. It means what is formed in the shape dimension.

  Such a film material can impart an aurora-like color tone based on the color of the container in which the film materials are laminated to the container surface. In addition, as the transparent film, a polyester film such as polyethylene terephthalate (PET), a polyolefin film such as polyethylene or polypropylene, a polyamide film such as nylon, and other cellulose or vinyl transparent films are used. Moreover, as said film material, various commercial items, such as the film which laminated | stacked many ultrathin transparent plastic films made from PET, are used, for example. Moreover, in order to make a container and the said commercial item stick easily, what laminated the polycarbonate (PC) etc. to the said commercial item is also used as the said film material. The thickness of the film material is usually set to about 1 to 100 μm.

  Further, when the film material is fixed to the surface of the resin molded body in a state of being bent along the prism-shaped uneven surface of the surface, the film material itself is bent along the prism-shaped uneven surface. As a result, the aurora-like optical color pattern appears to shine even more, resulting in a very deep three-dimensional color pattern. In the present invention, “the film material is fixed to the surface of the resin molded body” means that the film material is embedded in the surface of the resin molded body, The film material may be fixed on the surface of the resin molded body.

  In addition, when the prism-shaped uneven surface is formed by transferring the prism surface of the prism sheet onto the surface of the transparent resin molding, the prism-shaped surface can be obtained at low cost by using a commercially available prism sheet. An uneven surface can be formed.

  Next, embodiments of the present invention will be described in detail with reference to the drawings.
