Field of the Invention The present invention relates to a synthetic resin bottle body in which a shrink label made of a heat shrinkable film is wound and assembled, and a bottle having a flat surface portion in a body portion around which the shrink label is wound. It is about the structure of the body.

する手段が多用されている。2. Description of the Related Art As a liquid container, a synthetic resin bottle having many excellent characteristics is frequently used. This synthetic resin bottle, like a bottle made of another material, is printed on its surface. The display and decoration according to (1) and (2) are troublesome, and therefore, means for achieving these display and decoration by applying and winding a label are frequently used.

収縮性フィルム製のシュリンクラベルは、壜体に対する
組付きが強固で安定すること、巻回組付け操作が容易で
あること、壜体の表面構造に左右されないこと等の利点
を有している。Among the labels applied to synthetic resin bottles, the heat-shrinkable film shrink labels have strong and stable attachment to the bottle, easy winding and assembling operations, and bottles It has the advantage that it is not affected by the surface structure of the body.

れによりパネル壁部分が陥没変形しても壜体の外観が劣
化する恐れが全くないと云う利点がある。Particularly, in the case of a large bottle made of polyethylene terephthalate resin, in order to absorb the reduced pressure generated in the bottle, it is preferable to provide a recessed and deformable panel wall portion for absorbing the reduced pressure in the body of the bottle. Generally, even if there is a risk that the panel wall part will be depressed and deformed due to reduced pressure absorption and the appearance of the bottle as a container will be deteriorated, the shrink label can be attached to the body part having this panel wall part. For example, the panel wall portion can be concealed by the shrink label, which has the advantage that the appearance of the bottle body is never deteriorated even when the panel wall portion is depressed and deformed.

る。The winding and assembling of the shrink label on the body portion is carried out by fitting a shrink label formed in a tubular shape in advance on the body portion, heating the fitted shrink label, and circumferentially and vertically. It is contracted in the direction, and by this contraction deformation, it is firmly wound around and fixed to the body portion.

形し難い部分の収縮変形が停止しているのに、収縮変形
し易い部分の収縮変形は継続すると云う現象が生じ、シ
ュリンクラベルの部分間に収縮量の差が発生する。By the way, attachment of the shrink label to the body portion of the shrink label is achieved by heat shrink deformation of the shrink label, but the heat shrink deformation of the shrink label is not always necessary. It is not achieved uniformly over the entire area, and if there are parts that easily contract and deform due to differences in the contact state with the surface of the body part of the shrink label, parts that are difficult to contract and deform will stop contracting and deforming. However, there occurs a phenomenon that the contraction deformation of the part easily contracted and deformed continues, and a difference in contraction amount occurs between the parts of the shrink label.

に対向するシュリンクラベル部分が、他の胴部部分に対
向するシュリンクラベル部分に比べて収縮変形し易い状
態となり、より大きく収縮変形することになる。For this reason, when the body part around which the shrink label is wound has a flat wall such as a flat wall for providing a panel wall part for absorbing the reduced pressure, the shrink facing the flat wall. The label portion is more easily contracted and deformed as compared with the shrink label portion that faces the other body portion, and is contracted and deformed to a greater extent.

分の収縮変形だけが継続され、この結果、平坦壁に対向
するシュリンクラベル部分の上下幅が、他の部分のシュ
リンクラベル部分の上下幅よりも小さくなる。That is, when the shrink label is heat-shrinked and wrapped around the body portion with a certain amount of force, the shrink label strongly contacts the arc portion of the body portion or the side edge portion of the flat wall. While the shrink label is less likely to shrink and deform, the contact pressure of the shrink label on the flat wall is weak, so that only the shrink label portion of the shrink label facing the flat wall continues to shrink, resulting in shrink label facing the flat wall. The vertical width of the portion is smaller than the vertical width of the shrink label portion of the other portion.

劣化させると云う問題があった。Therefore, the upper or lower edge of the shrink label wound around the bottle and facing the flat wall is curved and deformed in the direction of narrowing the width of the shrink label, and the shrink label is wound. There was a problem of deteriorating the appearance of the bottle that was rotated.

に減少させることができないと云う問題があった。Further, as a conventional means for preventing the occurrence of this inconvenience, a linear step portion is provided along the circumferential direction on the lower edge and the upper edge of the flat wall, and the shrink label is caught by the step portion. Some attempts to stop the shrinking deformation of the shrink label part facing the flat wall at an early stage, but although the shrink label's shrinking deformation preventing effect by this step portion is certainly recognized, this shrink shrinking preventing effect that appears is The effect is lower in the central part than in the side end part of the step part, so that the degree of curving deformation of the edge of the shrink label portion facing the flat wall can be reduced, and the curving deformation of this edge is reduced. However, there is a problem in that it cannot be reduced to such an extent that the appearance is not deteriorated.

突出させた稜線構造とするのが有効である。A body is formed by surrounding a circumferential groove in the center of a rectangular tubular body having a substantially rectangular flat cross-section, and a body part around which a shrink label is wound in the upper half section defined by the circumferential groove. It is effective that the lower end edge which is a boundary ridgeline with the peripheral groove of the flat surface portion formed by the long side wall portion of the body portion has a ridge structure in which the central portion projects downward.

部部分に巻回状に強固に組付く。[Function] The shrink label previously formed into a cylindrical shape by the heat-shrinkable film is uniformly coated on the entire body of the bottle, by heating the whole body,
Heat shrinks in the circumferential direction, and due to this heat shrinkage deformation in the circumferential direction, it is firmly attached to the body portion in a wound shape.
【００１５】このシュリンクラベルの胴部部分に対する

リンクラベルには、周方向以外にも上下方向への熱収縮
が発生する。During the heat shrinkage deformation in the circumferential direction for attaching the winding assembly to the body portion of the shrink label, the shrink label undergoes heat shrinkage not only in the circumferential direction but also in the vertical direction.

は、平坦面部の両周角縁間に張設された状態となり、こ
のため両周角縁部分に比べて中央部分の胴部表面に対す
る接触圧力が弱くなる。Due to the thermal contraction of the shrink label in the circumferential direction, the shrink label portion facing the flat surface portion of the body portion is stretched between both circumferential corner edges of the flat surface portion. In comparison, the contact pressure on the surface of the body in the central portion becomes weaker.

形が継続する傾向となる。Therefore, in the state where the shrink label is wound around the body portion, in the shrink label portion facing the flat surface portion, both peripheral edge portions where the contact pressure with the body surface is strong are subject to vertical heat shrinkage deformation. At the center portion where the contact pressure with respect to the body surface is weak, the heat shrink deformation in the vertical direction tends to continue.

の端縁に沿って折れ曲がった状態となる。However, since at least one of the upper and lower edges of the flat surface portion has a step-like ridge structure in which the central portion inclines toward one side in the vertical direction rather than the side edge portion, the ridge structure is formed in the circumferential direction. The portion of the shrink label wound around the body portion due to the heat contraction of the flat surface portion facing the edge of the flat surface portion is bent along the edge.

ベル部分の上下方向への収縮変形の発生を阻止する。The structure of the shrink label makes the hook of the shrink label stronger as it approaches the central portion from the side end, so that the shrink label is wound around the body by the hook of the shrink label. After the turned state, the shrink label portion facing the flat surface portion is prevented from contracting and deforming in the vertical direction.

とになる。A peripheral groove is provided in the center of the rectangular tubular body, and the long side wall portion of the upper half portion is a flat surface portion.
If the boundary ridgeline with the circumferential groove of this flat surface portion is an edge projecting downward at the center, as long as the depth of the circumferential groove is constant, the degree of bending of the wall forming the ridgeline is Since it becomes the sharpest in the center part, the shrink label catches more strongly on the center part of the edge, and it is possible to ensure that heat shrinkage deformation occurs in the vertical direction after winding on the body part of the shrink label part facing the flat surface part. Will be blocked.

る。Since the present invention has the above-described structure, the following effects can be obtained. At least one edge portion above and below the portion of the shrink label wound around the body portion and facing the flat surface portion has a side edge portion at least one edge above and below the flat surface portion. Since it is caught by a catching force that strengthens as it approaches the center part, contraction deformation in the vertical direction is most likely to occur after the winding assembly is attached. It is possible to strongly prevent the occurrence, and it is possible to reliably prevent the appearance deterioration of the bottle body as a product due to the incorrect curved deformation of the upper and lower edges of the shrink label wound around the body. it can.

にかつ強力に阻止することができる。When the edge of the flat surface portion is defined as a boundary ridge line with the circumferential groove provided around the body portion with a uniform depth, the bending angle of the longitudinally-cut wall of this edge is from the side edge portion. As it gets sharper as it gets closer to the center part, it is possible to make the catch of the edge center part against the shrink label stronger.
Therefore, it is possible to more reliably and strongly prevent the occurrence of illegal shrinkage deformation of the shrink label.
