Description

  The present invention relates to a resin decorative container intended to be differentiated from other containers by a visual effect.

As a conventional decorative container, there is a container in which shades of color appear on the surface of a container body by filling the same resin at different timings (see, for example, Patent Document 1).
Utility Model Registration No. 3114093

  However, the visual effect is not only the color shading, but it is also true that there is a demand in the market to differentiate from other containers with a visual effect different from other containers.

  An object of the present invention is to provide a novel resin decorative container that can be differentiated from other containers by a visual effect different from color shading.

The resin decorative container according to the present invention has a thickness at the bottom of a container made of a transparent or translucent resin along the axial direction of the container, and forms an inner surface of the bottom on a smooth surface. A concave portion that can be seen through as a decorative outline is formed on the outer surface of the bottom portion, and is embedded in the concave portion so that the lower portion of the decorative body is exposed .

  Examples of the method for producing the container body according to the present invention include injection molding and blow molding. In addition, examples of the shape of the container body include a cylindrical shape and a prismatic shape.

  In addition, as the concave portion according to the present invention, for example, one having a contour constituted by complex unevenness, one having a contour constituted by a plurality of steps, a dome shape (semispherical or concave shape (curved surface or And the like having a contour of a shape composed of a plurality of planes).

  Moreover, according to this invention, a decorative body can be provided in the said recessed part. Various objects such as a toy typified by a small figure can be adopted as the decorative body as well as a spherical shape, an elliptical shape, a cylindrical shape and a prismatic shape. Further, as a decorative body, a transparent (including translucent) or opaque material, a wood-grained material, or a material having metallic luster can be adopted.

  According to the resin decorative container according to the present invention, the bottom of the container made of a transparent or translucent resin is given a thickness along the axial direction, and the outer surface of the bottom is seen through as a decorative outline. Since the concave portion is formed, when the concave portion is viewed through the side surface of the bottom portion or the like, a decorative effect is added to the contour of the concave portion due to the lens effect at the bottom portion.

  In addition, the container body can be manufactured by a relatively simple molding method because the bottom portion is thickened and the concave portion is formed on the outer surface thereof.

  Therefore, according to the present invention, it is possible to provide a novel resin decorative container that can be differentiated from other containers by a visual effect different from the color shading.

Further, by providing the decorative body in the concave portion according to the present invention, it is possible to increase the variation of the decoration by a simple operation of changing the decorative body. In addition, if a material having a specific gravity heavier than the resin constituting the container is adopted as the decorative body, a sense of stability when the container is grounded can be improved, and a feeling of weight can be given when the container is held.

  Hereinafter, a resin decorative container according to the present invention will be described in detail with reference to the drawings.

  Further, as shown in FIG. 1A, the bottom 5 has a thickness T (formed thicker than the shoulder 3 and the body 4) along the direction of the axis O, and the outer surface of the bottom 5 A bottom raised recess 10 is formed in 5 g (hereinafter referred to as “bottom outer surface”).

  Here, reference numeral 11 denotes an inclined surface that is inclined so as to approach the axis O as it rises toward the mouth 2, as shown in FIG. 1 (a). As shown in FIG. 1 (c), the inclined surface 11 is an annular portion that surrounds the axis O.

  Next, reference numeral 12 denotes a smooth surface surrounded by an annular inclined surface 11 as shown in FIG. The smooth surface 12 is formed so as to be substantially parallel to the inner surface 5f of the bottom portion 5. That is, the bottom-up concave portion 10 has a truncated cone shape in which the smooth surface 12 is surrounded by the annular inclined surface 11.

  Next, each form of the bottle according to the present invention will be described with reference to the basic bottle 1 described above.

FIGS. 2 (a) to 2 (c) are partially cross-sectional views of other synthetic resin decorative bottles (hereinafter referred to as “bottles”) 1 ′, which are referred to in describing the synthetic resin bottles according to the present invention. They are the side view shown by and the top view and bottom view which show it from upper direction. In the following description, the same parts as those in FIG. 1 are denoted by the same reference numerals, and the description thereof is omitted.

  Similar to the basic bottle 1, the bottom 5 has a thickness T along the direction of the axis O, as shown in FIG. 2 (a). The outer surface 5g of the bottom 5 has a watermark as a decorative outline. A recess 20 that can be seen is formed.

  Reference numeral 13 denotes a deformed surface having a contour constituted by complex uneven surfaces, as shown in FIGS. 2 (a) and 2 (c). That is, the recess 20 according to the present embodiment is a truncated cone shape surrounding the smooth surface 12 with an annular inclined surface 11, and a complex uneven surface provided on the upper portion of the smooth surface 12 forming the upper end of the truncated cone. Formed with a configured profile surface 13. Thereby, from the side surface of the bottom portion 5, it is possible to see through the recessed portion 20 having a shape having a plurality of protrusions and recesses.
