Abstract

PURPOSE:To eliminate the curling-up of the end of a film at thermal shrinkage by a method wherein main sealing is performed with ultrasonic wave at the middle of an overlapped portion of both the ends of the film and at the same time auxiliary sealing is also performed with ultrasonic wave at the upper side end edge of the film. CONSTITUTION:A main sealing part 2 is obtained by sealing the middle of an loverlapped portion of both the ends 3 and 4 of a shrinkable film 1 with ultrasonic wave. The slight crosswise distortion of said main sealing is permissible. the numeral 5 denotes an auxiliary, sealing produced by ultrasonic sealing along the upper side end 3. In addition, the auxiliary sealing 5 may be done simultaneously with or after the main sealing 2. Further, the intermittent auxiliary sealing 5 may be acceptable except the continuous auxiliary sealing 5. No curling- up of the end of the shrinkable film occurs by heating due to the auxiliary sealing provided along the end as mentioned above except the main sealing.

Description

【発明の詳細な説明】 本発明は、缶、瓶などのラベルとなるシュリンクラベル
フィルムの超音波シール方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an ultrasonic sealing method for shrink label films used as labels for cans, bottles, etc.

第１図は従来のシュリンクラベルフィルムの超音波シー
ル方法を示すもので、包装体Ｏ１に外被されるシュリン
クラベルフィルム０２の両端０３と０４を重ね合わせ、
この重ね合わせ部分の中間を超音波にて本シール０５す
るという方法である。FIG. 1 shows a conventional ultrasonic sealing method for shrink label films, in which both ends 03 and 04 of a shrink label film 02 to be covered with a package O1 are overlapped,
The method is to perform a main seal 05 on the middle of this overlapping portion using ultrasonic waves.

このため、シュリンクラベルフィルム０２が熱収縮した
際に、第２図に示すように、上側のシュリンクラベルフ
ィルムの端０３が跳ね上がり、外観を損ねるという欠点
があった。For this reason, when the shrink label film 02 is heat-shrinked, the upper end 03 of the shrink label film jumps up, as shown in FIG. 2, resulting in a disadvantage in that the appearance is impaired.

本発明は斯かる欠点の生じないシュリンクラベルフィル
ムのシール方法を提案するもので、超音波にてシールす
る際に、本シール以外に更に上側のフィルムの端を補助
シールする点に特長がある。The present invention proposes a method for sealing a shrink label film that does not suffer from such drawbacks, and is characterized in that when sealing is performed using ultrasonic waves, an auxiliary seal is applied to the upper edge of the film in addition to the main seal.

第３図は上記本発明シール方法の一実施例を示すもので

シール２は多少左右にズしてもよい。Fig. 3 shows an embodiment of the above-mentioned sealing method of the present invention, in which 1 is a shrink label film, 2 is a shrink label film in which both ends 3.4 are overlapped and the middle is sealed by ultrasonic waves. This is the actual seal part. Incidentally, the main seal 2 may be slightly shifted left and right.

補助シール５は連続以外に、断続的に行なってもよい。5 is an auxiliary seal sealed along the upper edge 3 by ultrasonic waves. Note that this auxiliary seal 5 may be performed simultaneously with the main seal 2, or may be performed later. or,
The auxiliary sealing 5 may be performed not only continuously but also intermittently.

本発明は以上のように、シュリンクラベルフィルムをシ
ールする際に１本シール以外に端をシールする補助シー
ルを行なうようにしたので、加熱収縮してもシュリンク
ラベルフィルムの端が跳ね上がることはない。As described above, in the present invention, when sealing a shrink label film, an auxiliary seal for sealing the edges is performed in addition to the single seal, so that the edges of the shrink label film do not jump up even when the shrink label film is heated and shrunk.

この結果、従来のように外観を損ねることがないと共に
本シール強度を損ねるという心配もない。As a result, there is no need to worry about the appearance being impaired as in the conventional case, and there is no fear that the seal strength will be impaired.
