Description

  The present invention relates to a synthetic resin bottle and a method for attaching a label to the bottle. The label attached to the body of the bottle is accurately attached in a predetermined direction to clarify product recognition and display the product. It tries to improve the appearance in time.

  Synthetic resin bottles such as plastic bottles are lightweight, easy to handle, and can be transparent, so they have an appearance comparable to glass containers. In addition, because of its low cost, it has been frequently used in recent years as a container for filling foods, beverages, cosmetics, drugs, and the like.

Usually, this type of container has a label (a cylindrical shrink label inserted so as to be covered from the top of the bottle and in close contact with the body by heat shrinkage) in order to clarify product recognition. (See, for example, Patent Document 1), in particular, there are a plurality of vacuum absorbing panels (mainly comprising six panels) around a barrel such as a heat-resistant bottle. In the provided container, irregularities are formed on the outer surface of the torso, so it may be difficult to recognize the printed characters and symbols depending on the orientation of the attached label, and it may not look good when displaying products was there.

  SUMMARY OF THE INVENTION An object of the present invention is to propose a synthetic resin bottle that makes it easy to read the characters and symbols on the label and has a good appearance when displaying a product, and a method for attaching the label to the bottle.

The present invention is a synthetic resin bottle having a mouth portion for pouring the contents, and subsequently forming the neck portion, shoulder portion, trunk portion and bottom portion integrally with the mouth portion,
A composite having at least one set of flat portions parallel to each other at opposite positions at a position below the mouth portion, and a neck ring that directs the body of the bottle in a certain direction starting from the flat portions. It is a resin bottle.

  In the synthetic resin bottle configured as described above, the neck ring preferably has a polygonal planar shape.

  The flat portion can be formed only on the lower surface of the neck ring, and the neck ring has a diameter larger than the outer shape of the cap that closes the mouth of the container, or the cap that closes the mouth of the container. It has a diameter equivalent to the outer diameter of.

In addition, the present invention is to attach a shrink label to the synthetic resin bottle having the above-described configuration.
A flat part of a neck ring provided below the mouth of the bottle is brought into contact with a guide rail or a jig of a bottle conveyance line, and a shrink label is attached in a state where the direction of the bottle itself is regulated in a certain direction. This is a method for attaching a label to a synthetic resin bottle.

  By providing flat parts parallel to each other at the opposing position of the neck ring and making the flat parts contact the guide rails or jigs in the bottle transport line, it becomes possible to keep the bottle in a certain direction. In addition, the label can be easily aligned with the bottle, the characters and symbols are not easily seen, and the appearance of the product is improved.

Hereinafter, the present invention will be described more specifically with reference to the drawings.
1 (a) and 1 (b) are views showing an embodiment of a synthetic resin bottle (heat-resistant beverage PET bottle) according to the present invention, wherein (a) is a plan view and (b) is a side view.

  In the figure, 1 is a mouth portion for pouring contents, 2 is a neck portion following the mouth portion 1, 3 is a shoulder portion, 4 is a torso portion, and 5 is a bottom portion, each of which is a test tube serving as a precursor. These preforms are integrally molded by biaxial stretch blow molding.

  Reference numeral 6 denotes a column provided in the body 4, 7 denotes a vacuum absorbing panel provided between the columns 6, and 8 denotes a neck ring provided below the mouth 1. The neck ring 8 has flat portions 8a and 8b whose edges are notched in parallel to each other at the opposing position.

  In order to form the flat portions 8a and 8b, the neck ring 8 is preferably formed in the same shape when the preform used as the precursor of the biaxial stretch blow molding is formed. The preform molding method is usually an injection molding method, but the present invention is not limited to this, and a known molding method such as a compression molding method or an extrusion molding method can be applied. This point can be appropriately selected.

  The above synthetic resin bottle is shown as an example in which flat portions 8a and 8b are provided on both sides of the neck ring 8 with the center in the width direction of the reduced pressure absorption panel 7 as the front, and the flat portions 8a and 8b are shown in FIG. It is possible to keep the reduced pressure absorption panel 7 always facing the front by carrying it in contact with the guide rails 9a and 9b of the carrying line as shown in the figure. When attaching the label, characters, symbols, etc. drawn on the label Can be easily aligned with the center of the bottle in the width direction of the reduced-pressure absorption panel 7 of the bottle.

  The neck ring 8 can be polygonal as shown in FIGS. 3 (a) and 3 (b), and the flat portions 8a and 8b may be formed only on the lower surface of the neck ring 8 in some cases. Good. In the case where the flat portions 8a and 8b are formed only on the lower surface of the neck ring 8, the corresponding part of the neck ring 8 has a stepped shape, but the guide rail of the contacting conveyance line has the stepped shape of the neck ring 8. It is also possible to make the shape suitable for the shape to be exhibited or a shape close to it.

  The label may be attached to the bottle after capping. In this case, the cap may not be able to direct the bottle in a certain direction by blocking the contact with the guide rail. Therefore, the diameter of the neck ring 8 is made equal to the outer shape of the cap that closes the mouth of the container, or larger than the diameter of the cap.

  By bringing the flat part of the support ring into contact with the guide rails and jigs of the transport line, the bottle can be directed in a certain direction, which makes it easy to align the bottle and label, and the center of the label and the bottle It is possible to provide a bottle that facilitates product recognition at a predetermined position.

It is the figure which showed embodiment of the synthetic resin bottles according to this invention, (a) is a top view, (b) is a side view. It is the figure which showed the conveyance condition of the bottle shown in FIG. It is the figure which showed other embodiment of the synthetic resin bottles according to this invention, (a) is a top view, (b) is a side view.
