Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to prevention of label displacement in a bottle with a half label attached, particularly a bottle with a half shrink label formed of a heat-shrinkable film on a bottle body.
[0002]
[Prior art]
Conventionally, it is well known that a shrink label formed of a heat-shrinkable film is heat-shrinked and adhered to the peripheral surface of the body or shoulder of the bottle.
When a shrink label is attached to the body, the upper end of the label is contracted and adhered to the shoulder circumferential surface or the inclined surface of the lateral rib provided between the shoulder and the body, and the lower end of the label is attached to the body and the bottom. In order to prevent the label after sticking from shifting, it is contracted and adhered to the inclined surface of the horizontal rib provided between the two.
In the case of a half-shrink label, the lower end of the label is contracted and adhered to the inclined surface of the lateral rib provided in the middle of the body so that the label does not shift up and down.
[0003]
Moreover, when sticking the shrink label on the shoulder peripheral surface, the upper end of the label is contracted and adhered to the curved surface of the shoulder, the lower end is contracted to the inclined surface of the lateral rib between the shoulder and the trunk, The shrink label does not shift up and down.
[0004]
[Problems to be solved by the invention]
Even in the case of a 500 ml bottle, even if it is a small-capacity bottle of around 500 ml or less, the lower end of the shrink label can be contracted and brought into close contact with the groove of the lateral rib by using the lateral rib arranged at the center of the trunk part. A half shrink label covering the upper half of the torso could be applied.
However, even in the case of a 500 ml bottle, a half-shrink label could not be applied if a lateral rib was not provided at the center of the trunk.
In addition, 200 to 400 ml small bottles of 500 ml or less, especially hot-filled bottles, are provided with 6 to 8 vacuum absorbing surfaces with vertical ribs as struts. Ribs could not be provided and half-shrink labels could not be employed.
Moreover, since the height of a shoulder part becomes low and a surrounding area also becomes small in a 200-400 ml bottle, the label surface required for a shoulder part was not securable.
[0005]
For this reason, in a small-capacity bottle, a full label has to be attached to the entire body using upper and lower lateral ribs disposed at the connection between the body and the shoulder and between the body and the bottom. Therefore, since the half shrink label cannot be used, there is a problem that an unnecessary portion is formed as a printed label, and label resources are wasted, and there is a problem that the manufacturing cost of the bottle is increased.
[0006]
An object of the present invention is to provide a bottle in which a half-shrink label is pasted and prevented from shifting up and down even in a small-capacity bottle of around 500 ml or less, in order to solve the above-mentioned problems. And
[0007]
[Means for Solving the Problems]
In order to achieve the technical problem described above, the present invention provides a bottle capable of adhering a half label, wherein a lateral rib is disposed at a connection portion between a shoulder portion and a trunk portion, and a plurality of vertical ribs are provided on the trunk portion. In a bottle having a vacuum absorbing surface, a label shift consisting of a plurality of convex portions on the surface of each vertical rib within a distance obtained by subtracting a predetermined width from the vertical width of the half shrink label from the end of the vertical rib. The structure characterized by arrange | positioning the prevention member is employ | adopted.
[0008]
As another example of a bottle that can be attached with a half label, in a bottle provided with a horizontal rib at the connection portion between the shoulder portion and the trunk portion, and provided with a plurality of vertical ribs and a vacuum absorbing surface on the trunk portion, A label displacement prevention member formed by a textured surface is disposed on the surface of each vertical rib within a distance obtained by subtracting a predetermined width from the vertical width of the half shrink label from the end of the vertical rib. Adopt the configuration.
[0009]
In order to allow corrugated half-shrink labels to be attached, the distance from the end of the vertical rib at the position where the label displacement prevention member is arranged is different for each vertical rib. In addition, in order to allow the half-shrink label to be attached to the upper portion, the lower portion of the trunk portion, or a desired position, the lateral ribs are disposed at the connecting portion between the shoulder portion and the trunk portion and the connecting portion between the trunk portion and the bottom portion, In the bottle having a plurality of vertical ribs and a reduced pressure absorbing surface in the body portion, a configuration is adopted in which a label displacement prevention member is disposed at the center of the surface of each vertical rib.

Next, a fifth embodiment will be described.
In each said embodiment, although the horizontal rib is arrange | positioned between the shoulder part and the trunk | drum, if the intensity | strength of a bottle can be ensured, it is not necessary to provide a horizontal rib.
In the present embodiment, the shoulder 2 and the body 3 are made continuous by eliminating the lateral rib.
The circumferential edge of the lower end of the shoulder 2 coincides with the upper edge of the surface of the circular arc wall 10a of each vertical rib 10 of the trunk 3, and a convex portion or a textured surface is formed at a predetermined position above the circular arc wall 10a. (Not shown).
When sticking the half-shrink label, the upper end of the label is contracted and adhered to the surface of the shoulder 2, and the lower end of the label is contracted and adhered to the convex portion or the embossed surface provided on the surface of the arc wall 10 a.
This makes it possible to apply a half-shrink label to the shoulder surface using a certain portion of the upper end of the trunk portion even if the shoulder area is small, and change the upper lateral rib to the lower end portion of the shoulder portion. It is also possible to use the same cylindrical half shrink label as in the above embodiments.
[0032]
In each of the embodiments, the specific absorption surface has been described as the reduced pressure absorption surface. However, if all of the absorption surface is an absorption surface located radially inward from the surface of the arc wall, the cross section of the absorption surface Then, it may be a flat surface or a circumferential surface, and is not limited to that described in the embodiment.
[0033]
【The invention's effect】
Since this invention is comprised as mentioned above, there exists the following effect.
Since a label displacement prevention member is disposed on the surface of each vertical rib within a distance corresponding to the vertical width of the half shrink label from the end of the vertical rib, the half shrink label can be attached even in a small capacity bottle. It was.
Therefore, the amount of label used can be reduced, and the manufacturing cost as a bottle can be reduced.
By selecting the position of the label displacement prevention member, the label can be attached to a desired position between the upper and lower parts of the body part and in the middle.
