本発明はインモールドラベルを備えたボトルと、そのブ
ロー成形方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a bottle equipped with an in-mold label and a blow molding method thereof.
従来、ラベルに凹凸を形成し、この凹凸でラベルの表面
に文字、模様等を表わしたラベルを、ボトルの胴部に貼
着することが知られている。2. Description of the Related Art Conventionally, it has been known to form irregularities on a label, and to attach a label, in which letters, patterns, etc. are expressed on the surface of the label using the irregularities, to the body of a bottle.
前記従来の手段では、積み重ねたラベルの凹凸部が嵌合
して剥離し難くなり、ラベルの供給が困難であった。In the conventional means, the uneven parts of the stacked labels fit together and become difficult to peel off, making it difficult to supply the labels.
また、ラベルの貼着時に、ラベルの凸部が抑圧されて扁

た。Further, when the label was attached, the convex portion of the label was suppressed and became flat, reducing the commercial value of the bottle.
本発明は前記事項に鑑みなされたものであり、ラベルの
供給がし易く、かつ、接着されたラベルの凸部が扁平状
とならないようにすることを技術的課題とする。The present invention has been made in view of the above-mentioned problems, and its technical object is to facilitate the supply of labels and to prevent the convex portions of the adhered labels from becoming flat.

。This claim! The described invention is a blow-molded bottle 10, in which a label 5 is adhered to an outer wall portion 11 of the bottle IO, and a convex portion 7 representing a pattern character or the like is formed on the label 5. In the recessed part 6 formed on the back side of the convex part 7 of this label 5,
The outer wall part 11 of the bottle 10 enters and forms a convex part 12,
Further, the bottle is equipped with an in-mold label in which compressed air is sealed in the recessed part 6 of the label 5.

モールドラベルを備えたボトルの成形方法とした。The invention according to claim 2 provides the following: A recess 2 is provided on the inner surface of a mold l for blow molding, and a label 5 covering the recess 2 is placed inside the portion of the mold l where the recess 2 is provided. Then, the heated preform is placed in the cavity of the mold 1, the mold 1 is closed, air is blown into the preform to expand it, and the label on the front part of the recess 2 is removed. 5, a recessed part 6 is formed on the back side of the white label 5 in the recessed part 2, and further,
The outer wall portion 11 of the bottle 10 formed by expanding the preform is entered into the recessed portion 6 to form a convex portion 12;
A method of molding a bottle with an in-mold label in which a convex part 7 is formed on the surface of the label 5 so that compressed air is confined in the concave part 6 by the convex part 12 is adopted.

ようにしたので、ラベル５の凸部７は圧縮空気により突
出し、扁平状とならない。In the invention as claimed in claim 1, the outer wall portion 11 of the bottle 10 enters into the concave portion 6 on the back side of the convex portion 7 representing the pattern, characters, etc. of the label 5 adhered to the outer wall portion 11 of the bottle 10 to form a convex portion. Since the inlet part 12 is formed to confine compressed air in the recessed part 6, the convex part 7 of the label 5 protrudes due to the compressed air and does not become flat.

に圧縮空気が封じ込められる。According to the second aspect of the invention, when air is blown into the preform placed in the cavity of the mold l, the preform expands and compresses the air in the cavity. This compressed air presses the label 5 on the front side of the recess 2 of the mold l to whiten the inside of the recess 2, forming a recess 6 on the back side of the label 5, and further expands the preform. The outer wall portion 11 of the bottle IO, which has been formed as described above, enters into the recessed portion 6 to form a convex portion 12. Compressed air is confined within the recessed portion 6 by the recessed portion 12.

This label 5 is formed with a convex portion 7 representing characters, and the outer wall portion 11 of the bottle 10 enters into a concave portion 6 formed on the back side of the convex portion 7 of this label 5 to form a stopper-like shape. The bottle is equipped with an in-mold label in which a convex part 12 is formed, and compressed air is sealed in a concave part 6 of the label 5.

It is adsorbed and arranged on the charged mold l. Furthermore, a preform made of polyethylene heated to a molding temperature is placed in the cavity of this mold 1, and the mold 1 is closed to allow the brief form to expand.

ラベル５の凹入部６内に圧縮空気を封じ込める。Furthermore, a bottle 10 formed by expanding the preform
By blowing air into the container, the outer wall 11 of the bottle IO enters the recess 6 to form a recess 12, as shown in FIGS. 4 and 5. Compressed air is confined within the recess 6 of the label 5 by the recess 12.

突出して第２図に示す如くなる。Furthermore, after the molded bottle 10 has cooled, the mold l is opened and the bottle 10 is taken out from the mold l. Then,
The compressed air sealed in the concave portion 6 of the label 5 causes the convex portion 7 of the label 5 to protrude further than the protruding height shown in FIG. 5, as shown in FIG. 2.

うことがなく、供給が容易である。According to the second aspect of the invention, the convex portion 7 of the label 5 is formed during blow molding, so that the supplied label has no irregularities. Therefore, when the labels are being supplied, the concave and convex portions of the upper and lower labels do not fit together and become difficult to peel off, and the label can be easily supplied.
