  The present invention relates to a laminated container made of synthetic resin focusing on tactile properties.

  In the synthetic resin container, for example, an inner layer body made of synthetic resin in which a pouring cylinder is integrally provided on the upper part of the trunk via a shoulder portion, and an outer layer laminated so as to cover the outer surface of the inner layer body Some have a body (see, for example, Patent Document 1).

JP-A-7-205951

  However, the outer layer body according to the conventional laminated container is merely a protective layer that protects the inner layer body from an impact from the outside and a shielding layer that maintains the quality of the contents, and is gripped by the user. However, it was not constructed focusing on the original function of the outer layer body.

  An object of the present invention is to provide a new synthetic resin-made laminated container having a characteristic of feeling when grasped.

  The synthetic resin-made laminated container according to the present invention includes a synthetic resin inner layer body integrally provided on the upper portion of the trunk via a shoulder portion, and at least one around the dispensing cylinder of the inner layer body. The outer layer body is formed with a soft material, and the outer layer body is formed of a soft material.

  As the synthetic resin constituting the inner layer body, for example, a resin mainly composed of PET (polyethylene terephthalate) PP (polypropylene) can be mentioned. Furthermore, an elastomer is mentioned as a soft material which comprises an outer layer body, for example.

  Further, the outer layer body can be formed into a cylindrical portion by covering the entire circumference of the extraction cylinder, but according to the present invention, by forming a concave groove in the extraction cylinder of the inner layer body, At least part of the periphery of the dispensing tube can extend from the tip toward the shoulder. The laminated container made of a synthetic resin according to the present invention, for example, inserts an inner layer body as an insert product into a mold, and then injects a molten soft resin so that the composite material is injected. It can be molded as an integral part.

  According to the present invention, the outer layer body can be provided from the tip of the dispensing tube to the trunk through the shoulder. Moreover, according to this invention, an outer-layer body can also be provided from the front-end | tip to the shoulder part of the extraction | pouring cylinder.

  According to the present invention, when the outer layer body is gripped without impairing the original function of the inner layer body for the purpose of storing and dispensing the contents, the gripping deformation and the restoring force against the deformation cause A feeling (mat feeling) is good.

  Further, according to the present invention, for example, as an insert molding, an inner layer body is loaded as an insert into a mold, and then a molten soft resin is injected to form an integral product of a composite material. In this case, the trace of the injection gate does not remain in a portion where it is easy to obtain a feeling such as a shoulder portion or a trunk portion, and the original feel of the soft material can be obtained. Furthermore, according to the present invention, since there is no decoration (printing, vapor deposition, etc.) in a subsequent process, even if it is rubbed strongly, it will not be peeled off.

  Therefore, according to the present invention, it is possible to provide a novel synthetic resin-made laminated container that is characterized by a feel when gripped.

  In particular, when the outer layer body is provided from the tip of the dispensing tube to the trunk through the shoulder, a good mat feeling can be obtained over almost the entire laminated container.

  Further, if the outer layer body is provided from the tip of the dispensing tube to the shoulder, the body portion of the inner layer body is exposed to the outside without being covered by the outer layer body. For this reason, if the part which is not covered with the said outer layer body, such as coloring an outer layer body, is utilized, the visual effect resulting from the inner layer body can be added with a favorable mat feeling.

It is a perspective view which shows the 1st form of this invention. (a), (b) is the top view of the same form, and the side view which shows the same form in a partial cross section, respectively. It is a perspective view which shows the 2nd form of this invention. It is a side view which shows the same form in a partial cross section.

  Hereinafter, a laminated container made of a synthetic resin according to the present invention will be described in detail with reference to the drawings.

  1 and 2 show a bottle-type laminated container (hereinafter referred to as “laminated bottle”) which is a first embodiment of the present invention.

  Reference numeral 1 denotes an inner layer body that forms a space C (hereinafter referred to as “filling space”) C in which contents are filled. The inner layer body 1 is a bottle-shaped container made of a transparent or semi-transparent synthetic resin containing PP as a main component, and a pouring cylinder 1a integrally provided on the upper portion of the body 1c via a shoulder portion 1b. The contents in the filling space C are poured out through a pouring path P formed inside the pouring cylinder 1a. In this embodiment, the bottom 1d is configured as a separate body, and the bottom 1d is assembled to the lower end of the body 1c. However, the bottom 1d is omitted.

  Reference numeral 2 denotes an outer layer body that covers the outer surface of the inner layer body 1. The outer layer body 2 is made of, for example, a soft material such as an elastomer, and is provided so as to be hung on the trunk portion 1c via the shoulder portion 1b. Thereby, when the outer layer body 2 is gripped, the grip feeling (mat feeling) becomes good due to the deformation accompanying the grip and the restoring force against the deformation.

  In particular, in this embodiment, a concave groove G extending from the tip 1e of the extraction cylinder 1a toward the shoulder 1b is formed in a part of the extraction cylinder 1a of the inner layer body 1 around the extraction cylinder 1a. Is formed. As a result, the outer layer body 2 is inserted into the mold with the inner layer body 1 as an insert product, and then a soft resin typified by a molten elastomer is used, with the tip 1e of the dispensing cylinder 1a as an injection gate. It is formed on the outer surface of the inner layer body 1 by injecting along the groove G from 1e.

  In this embodiment, the outer layer body 2 has a belt-like portion 2a that forms part of the screw portion S formed in the extraction portion 1a, an annular portion 2b that occupies the entire shoulder portion 1b, and a body portion 1c over the entire circumference. It is comprised with the surrounding cylindrical part 2c. That is, the laminated bottle according to the present embodiment is molded as an integrated product of composite material by injecting molten soft resin after the inner layer body 1 is loaded into the mold as an insert product.

  According to the present embodiment, when the outer layer body 2 is gripped without impairing the original function of the inner layer body 1 for the purpose of storing and dispensing the contents, due to the deformation accompanying the grip and the restoring force for the deformation, The grip feeling (mat feeling) becomes good.

  Further, according to the present embodiment, for example, as an insert molding, after the inner layer body 1 is loaded as an insert into a mold, a molten soft resin is injected to form an integrated product of the composite material. In this case, the impression of the injection gate does not remain in a portion where it is easy to obtain a feeling such as the shoulder portion 1b and the trunk portion 1c, and the original feel of the soft material can be obtained.

  Therefore, according to the present embodiment, it is possible to provide a novel laminated container that has a feature in feel when grasped.

  Further, if the outer layer body 2 is provided from the tip 1e of the dispensing cylinder 1a to the body 1c via the shoulder 1b as in the present embodiment, a good mat feeling can be obtained over almost the entire laminated container. be able to.
