Abstract

To provide a container for shrink package in which a shrink film is filled as steadying to the outer face even if the outer shape is a different shape, and which can become a product with good externals.SOLUTION: A container for shrink package of this invention has a right-left asymmetry shape. A drum portion has a first wall face and a second wall face that are mutually opposed as interposing a center axis line in a right-left asymmetry direction. A bottom portion has a bottom face which intersects with the center axis line, and a cut face which is parallel to the center axis line toward the bottom face side from the lower side of the first wall face or inclines toward the direction in which distance from the center axis line becomes small. The first wall face is located on the side of the center axis line compared with a first straight line which connects a first intersection and a first shoulder portion side intersection. The second wall face becomes a convex shape outward so as to leave from the center axis line compared with a second straight line which connects a second shoulder portion side intersection and a bottom portion side intersection. The cut face is formed in a range including at least a position that leaves most from the center axis line in a periphery of the bottom face.SELECTED DRAWING: Figure 1

Description

  The present invention relates to a shrink wrapping container.

  Conventionally, many products in which the outer surface of a container for storing contents such as a detergent is covered with a shrink film on which a product name, a product description, and the like are described are sold in stores. Shrink-wrapped products are widely used because they are resistant to dirt and have a high-class feel. As a form of shrink wrapping, there are various wrapping forms such as a type in which the entire product is covered with a shrink film and a type in which a part of the container is partially covered (shrink label).

  For example, in a trigger type ejector that ejects contents in a container by operating a trigger, most of the outer surface of the container is often covered with a shrink film except for the ejector attached to the upper end of the container. In order to make it easy to attach the shrink label, the shape of the container is often generally symmetrical with respect to the center axis along the vertical direction, for example. In addition, for example, one or both of the outer peripheral surfaces of the container that face each other through the central axis is generally along the central axis or have a gentle downward slope toward the bottom. In many cases, the shape is simple.

  However, in recent years, bottle designs that are conscious of novelty have been proposed (for example, Patent Documents 1 to 4), and there has been a problem that the shrink label cannot be loaded successfully on the outer peripheral surface of the container.
