mmとするのが好ましく、長さを１０〜１００mmとするの
が好ましく、深さを１〜５mmとするのが好ましい。The present invention has the following features to attain the object mentioned above. That is, the container of the present invention, on its outer surface, provided in a plurality of rows in the axial direction of the container, concave portions that are recessed in the thickness direction of the container at intervals in the circumferential direction of the container,
It is characterized in that the recesses of the rows adjacent to each other are arranged alternately. The recess has a width of 1 to 10
mm, the length is preferably 10 to 100 mm, and the depth is preferably 1 to 5 mm.
【０００８】シュリンクフィルムは１軸配向と２軸配向

が向上する。When a shrink film is placed on a container and thermally shrunk, even if a force that causes wrinkles acts on the shrink film, the portion of the shrink film disposed above the recess absorbs the wrinkles. Therefore, the shrink film can be coated on the outer surface of the container neatly without wrinkles. As a result, even if the shrink film before heat shrinking is printed in advance with a product name or the like, the printed characters and the like do not become distorted after being attached to the container, the appearance is improved, and the quality is improved.
【００１０】又、容器はその断面形状が複雑になるた

については図６を援用する。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 is an enlarged front view of a main part of a container according to a first embodiment of the present invention, FIG. 2 is a sectional view taken along the line AA of FIG. 1, and FIG. 3 is a sectional view taken along the line BB of FIG. It is.
FIG. 6 is referred to for an overall external view of the container provided with the shrink film.
【００１２】容器としてのＰＥＴボトル１の胴部１０の
外表面には多数の凹部１１が規則的に散在配置されてい
る。凹部１１は内側に凹んでおり、各凹部１１は胴部１
０の周方向に沿って細長く形成されている。この凹部１
１の幅Ｗは１〜１０mmにするのが好ましく、長さＬは１
０〜１００mmにするのが好ましく、深さＤは１〜５mmに
するのが好ましい。On the outer surface of the body 10 of the PET bottle 1 as a container, a large number of recesses 11 are regularly scattered. The recesses 11 are recessed inward, and each recess 11 is
It is formed to be elongated along the circumferential direction of 0. This recess 1
The width W of one is preferably 1 to 10 mm, and the length L is 1
The depth D is preferably 0 to 100 mm, and the depth D is preferably 1 to 5 mm.
