Description

本発明は、ボトルに関する。   The present invention relates to a bottle.

従来から、合成樹脂材料で有底筒状に形成されたボトルとして、例えば下記特許文献１に示されるように、筒状の胴部に、その径方向の内側に向けて窪み、かつ全周に亘って連続して延びる周溝がボトル軸方向に間隔をあけて複数形成された構成が知られている。
この構成によれば、ボトルの径方向の剛性を高めることができるので、例えば胴部にラインプレッシャーが作用したとき、あるいはボトルに密封された内容物の温度が低下してボトル内が減圧した場合等に、胴部の変形を抑えるようになっている。 Conventionally, as a bottle formed into a bottomed cylindrical shape with a synthetic resin material, for example, as shown in Patent Document 1 below, the cylindrical body portion is recessed toward the inner side in the radial direction, and on the entire circumference. A configuration is known in which a plurality of circumferential grooves extending continuously are formed at intervals in the bottle axial direction.
According to this configuration, since the rigidity in the radial direction of the bottle can be increased, for example, when the line pressure acts on the body portion, or when the temperature of the contents sealed in the bottle is lowered and the inside of the bottle is decompressed For example, the deformation of the body portion is suppressed.

特開２００４−２６２５００号公報JP 2004-262500 A

ところで、上述したボトルにあっては、商品名や内容物、バーコード等の表示、意匠性向上の観点から、例えばシュリンクラベルや、ストレッチラベル、ロールラベル、タックラベル等といったラベルが胴部に取り付けられる。   By the way, in the bottles described above, labels such as shrink labels, stretch labels, roll labels, tack labels, etc. are attached to the body from the viewpoint of improving the display of product names, contents, barcodes, etc. It is done.

しかしながら、上述した従来の技術では、周溝が径方向の内側に向けて凹設されているため、特にシュリンクラベルを用いた場合、ラベル収縮時に周溝の形状にラベルが追随することになる。そのため、ラベルのうち、周溝を覆う部分と、周溝以外を覆う部分と、でラベルの収縮量が異なり、ラベルがボトル軸方向に沿って波打つような形状になって、ラベルの外観に違和感（外観不良）を生じる場合がある。
このような場合には、ラベルの絵柄等が歪んだり、ラベルに印字されたバーコード等が読み取り難くなったりする虞がある。 However, in the conventional technique described above, the circumferential groove is recessed toward the inside in the radial direction. Therefore, particularly when a shrink label is used, the label follows the shape of the circumferential groove when the label is contracted. Therefore, the amount of shrinkage of the label differs between the part that covers the circumferential groove and the part that covers other than the circumferential groove in the label, and the label has a shape that undulates along the bottle axis direction. (Poor appearance) may occur.
In such a case, there is a possibility that the design of the label is distorted, or the barcode printed on the label becomes difficult to read.

そこで、本発明は、上述した事情に鑑みてなされたものであって、その目的は、径方向への所望の剛性を維持した上で、胴部に取り付けられるラベルに外観不良が発生するのを抑制できるボトルを提供することである。   Therefore, the present invention has been made in view of the above-described circumstances, and its purpose is to maintain a desired rigidity in the radial direction and to cause appearance defects on the label attached to the trunk. It is to provide a bottle that can be suppressed.

上記課題を解決するために、本発明は以下の手段を提案している。
本発明に係るボトルは、筒状の胴部に、その径方向の内側に向けて窪み、かつ全周に亘って延設された周溝がボトル軸方向に間隔をあけて複数形成されたボトルであって、前記周溝は、径方向の内側に位置する底壁部と、該底壁部にボトル軸方向の両側から各別に連なり径方向の外側に向けて延びる一対の横側壁部と、により画成され、前記底壁部には、該底壁部からの径方向の外側に向けた突出量が、前記周溝の溝深さの半分以上で、かつ該溝深さの大きさ以下である突条部が、前記一対の横側壁部との間に隙間を設けた状態で、全周に亘って延設されていることを特徴としている。 In order to solve the above problems, the present invention proposes the following means.
The bottle according to the present invention is a bottle in which a plurality of circumferential grooves that are recessed toward the inside in the radial direction and extend over the entire circumference are formed at intervals in the bottle axis direction in a cylindrical body portion. The circumferential groove has a bottom wall portion located on the inner side in the radial direction, a pair of lateral side wall portions extending from the both sides in the bottle axial direction to the bottom wall portion and extending outward in the radial direction, The bottom wall portion has a protruding amount radially outward from the bottom wall portion that is not less than half of the groove depth of the circumferential groove and not more than the size of the groove depth. The projecting ridges are extended over the entire circumference with a gap provided between the pair of side wall portions.

このような特徴により、胴部に周溝が形成されているため、例えばラインプレッシャーやボトル内の減圧等による胴部の変形を抑えることができる。
特に、周溝の底壁部に、径方向の外側に向けて突出する突条部が形成されているため、周溝を覆うように胴部に巻き付けられるラベルを、突条部により径方向の内側から支持することができる。そのため、ラベル装着時において、周溝を覆うラベルが径方向の内側へ移動するのを規制できる。これにより、胴部に装着されたラベルが、周溝内に食い込むのを抑制し、ラベルに外観不良が発生するのを抑制できる。
また、突条部の突出量が、溝深さの大きさ以下になっているため、ラベルの収縮時等に突条部が干渉するのを抑制し、ラベルのうち、突条部を覆う部分が胴部に対して径方向の外側に突出するのを確実に防止できる。したがって、ラベルに外観不良が発生するのを確実に抑制できる。
以上より、周溝により径方向への所望の剛性を維持した上で、胴部に取り付けられるラベルに外観不良が発生するのを抑制できる。 Due to such a feature, since the circumferential groove is formed in the body portion, it is possible to suppress deformation of the body portion due to, for example, line pressure or pressure reduction in the bottle.
In particular, since a protrusion that protrudes outward in the radial direction is formed on the bottom wall of the circumferential groove, a label that is wound around the trunk so as to cover the circumferential groove is formed in the radial direction by the protrusion. It can be supported from the inside. Therefore, it is possible to restrict the label covering the circumferential groove from moving inward in the radial direction when the label is mounted. Thereby, it can suppress that the label with which the trunk | drum was mounted | worn enters in a surrounding groove, and can suppress that the appearance defect generate | occur | produces in a label.
Moreover, since the protruding amount of the protruding portion is equal to or less than the depth of the groove, it is possible to suppress the protruding portion from interfering when the label is contracted, and the portion of the label that covers the protruding portion. Can be reliably prevented from projecting radially outward with respect to the body portion. Therefore, it is possible to reliably suppress the appearance defect from occurring on the label.
As described above, it is possible to prevent the appearance defect from occurring in the label attached to the trunk portion while maintaining the desired rigidity in the radial direction by the circumferential groove.

また、上記本発明のボトルにおいて、前記底壁部には、前記一対の横側壁部同士を、前記突条部を介してボトル軸方向に連結する縦リブが、周方向に間隔をあけて複数配設されていてもよい。   Further, in the bottle of the present invention, the bottom wall portion includes a plurality of longitudinal ribs that connect the pair of lateral side wall portions to each other in the bottle axial direction via the protrusions at intervals in the circumferential direction. It may be arranged.

この場合には、周溝内に縦リブが配設されているため、底壁部に突条部を配設したことによるボトルの座屈強度の低下を抑えることができる。   In this case, since the vertical rib is disposed in the circumferential groove, it is possible to suppress a decrease in the buckling strength of the bottle due to the provision of the protrusion on the bottom wall.

また、上記本発明のボトルにおいて、前記縦リブは、複数の前記周溝に各別に形成されるとともに、それぞれの前記周溝における前記縦リブの周方向に沿う配設位置が互いに同等になっていてもよい。   In the bottle of the present invention, the vertical ribs are formed separately in the plurality of circumferential grooves, and the arrangement positions along the circumferential direction of the vertical ribs in the circumferential grooves are equal to each other. May be.

この場合には、ボトルの座屈強度の低下を確実に抑えることができる。   In this case, it is possible to reliably suppress a decrease in the buckling strength of the bottle.

本発明に係るボトルによれば、径方向への所望の剛性を維持した上で、胴部に取り付けられるラベルに外観不良が発生するのを抑制できる。   According to the bottle according to the present invention, it is possible to suppress the appearance defect from occurring in the label attached to the body part while maintaining the desired rigidity in the radial direction.

特に、周溝１５の底壁部３２に、径方向の外側に向けて突出する突条部３４が形成されているため、周溝１５を覆うように胴部１３に巻き付けられるラベルを、突条部３４により径方向の内側から支持することができる。そのため、ラベル装着時において、周溝１５を覆うラベルが径方向の内側へ移動するのを規制できる。これにより、胴部１３に装着されたラベルが、周溝１５内に食い込むのを抑制し、ラベルに外観不良が発生するのを抑制できる。
また、突条部３４の突出量Ｄ１が、溝深さＤ２の大きさ以下になっているため、ラベルの収縮時等に突条部３４が干渉するのを抑制し、ラベルのうち、突条部３４を覆う部分が胴部１３に対して径方向の外側に突出するのを確実に防止できる。したがって、ラベルに外観不良が発生するのを確実に抑制できる。
以上より、周溝１５により径方向への所望の剛性を維持した上で、胴部１３に取り付けられるラベルに外観不良が発生するのを抑制できる。 In the present embodiment, since the circumferential groove 15 is formed in the body portion 13, deformation of the body portion 13 due to, for example, line pressure or pressure reduction in the bottle 1 can be suppressed.
In particular, since a protrusion 34 protruding outward in the radial direction is formed on the bottom wall portion 32 of the circumferential groove 15, a label that is wound around the trunk portion 13 so as to cover the circumferential groove 15 is used as a protrusion. The portion 34 can be supported from the inside in the radial direction. Therefore, when the label is mounted, it is possible to restrict the label covering the circumferential groove 15 from moving inward in the radial direction. Thereby, it can suppress that the label with which the trunk | drum 13 was mounted | worn enters the surrounding groove 15, and can suppress that the appearance defect generate | occur | produces in a label.
In addition, since the protrusion amount D1 of the protrusion 34 is less than or equal to the groove depth D2, it is possible to suppress the protrusion 34 from interfering when the label is contracted. It is possible to reliably prevent the portion covering the portion 34 from protruding outward in the radial direction with respect to the body portion 13. Therefore, it is possible to reliably suppress the appearance defect from occurring on the label.
As described above, it is possible to prevent the appearance defect from occurring in the label attached to the body portion 13 while maintaining the desired rigidity in the radial direction by the circumferential groove 15.

しかも、本実施形態では、周溝１５内に縦リブ１５ａが配設されているため、底壁部３２に突条部３４を配設したことによるボトル１の座屈強度の低下を抑えることができる。
この場合、各縦リブ１５ａが複数の周溝１５に各別に形成されるとともに、それぞれの周溝１５における縦リブ１５ａの周方向に沿う配設位置が互いに同等になっているため、ボトル１の座屈強度の低下を確実に抑えることができる。 In addition, in the present embodiment, since the vertical ribs 15a are arranged in the circumferential groove 15, it is possible to suppress a decrease in the buckling strength of the bottle 1 due to the provision of the protrusions 34 on the bottom wall part 32. it can.
In this case, each of the vertical ribs 15a is separately formed in the plurality of circumferential grooves 15, and the arrangement positions along the circumferential direction of the vertical ribs 15a in the respective circumferential grooves 15 are equal to each other. A decrease in buckling strength can be reliably suppressed.
