【考案の詳細な説明】
本考案は巻取り開口缶に関し、さらに詳しくは
胴部の２条の周状のスコア線によつて画定される
帯状部を、スコア線を引裂きながら巻取ることに
よつて開口可能な巻取り開口缶に関する。[Detailed description of the invention] The present invention relates to a roll-up can, and more specifically, by winding up a belt-shaped can defined by two circumferential score lines on the body while tearing the score lines. The present invention relates to a roll-up can that can be opened with a roll.
巻取り開口缶の側面接合部は、従来主としてロ

されていた。しかしながら鉛を含む半田は衛生上
問題があり、一方純錫半田は高価であるという問
題を有する。さらに錫めつき鋼板以外の缶用金属
板、例えばテインフリースチール（電解クロム酸
処理鋼板）やアルミニウム（合金）板に対して
は、半田による接合を適用することは不可能であ
る。 Conventionally, side joints of roll-up cans have been mainly formed by joining lock parts with solder. However, solder containing lead has a problem in terms of hygiene, while pure tin solder has the problem of being expensive. Furthermore, it is impossible to apply soldering to metal plates for cans other than tin-plated steel plates, such as stain-free steel (electrolytic chromic acid treated steel plates) and aluminum (alloy) plates.
従つてその対策として、現在ビール、炭酸飲

缶が注目される。 Therefore, as a countermeasure, adhesive films (mainly nylon
Of interest is a can with a body having a side joint consisting of a wrap seam heat-sealed through a polyester material (Nylon 11, Nylon 12 or a copolymer or blend thereof).
第１図の１は、このタイプの巻取り開口缶を示

状のスコア線７が形成されている。 Reference numeral 1 in FIG. 1 shows a roll-up can of this type, in which the side joint 3 of the body 2 consists of a lap seam. A tongue-like piece 5 is provided in the vicinity of the lid part 4 of the side joint part 3, and extends in the circumferential direction from the outer edge part 3a of the lap part . There are formed two circumferential score lines 7 with relatively narrow intervals (for example, about 5 mm) extending along the outer surface of the body 2 through the notch 6 and going around the body 2.
開缶は、舌状片５を巻取り用キー（図示されな
い）の孔部に挿入して、舌状片５、およびスコア
線７によつて画定される帯状部８をキーに巻付け
ながら、キーを矢印Ａ方向に移動させて、スコア
線７を引裂くことによつて行なわれる。 The can opening is performed by inserting the tongue 5 into the hole of a winding key (not shown) and winding the tongue 5 and the band 8 defined by the score line 7 around the key. This is done by moving the key in the direction of arrow A and tearing the score line 7.

と、側面接合部近傍の当該スコア線に沿う横断面
図は第２図に示すようになる。 By the way, as in the case of a body part having a side joint made of a conventional lock solder joint, a score line is formed over the entire length between the opposite edges of the body part blank, and a wrap seam is formed from the body part blank. When a body portion having a side joint portion consisting of a portion is formed, a cross-sectional view along the score line in the vicinity of the side surface joint portion becomes as shown in FIG.

An adhesive film layer is heat-bonded in advance to cover the end surface portion 3'b1 , and the adhesive film layers 9a and 9b are heat-sealed to each other. Although not shown, the inner and outer surfaces of the metal plate constituting the body, the outer edge 3'a, and the inner edge 3'b are coated with a suitable primer, such as an epoxy-phenol baking coating. There is. The portion 9b 1 of the adhesive film layer 9b that is in contact with the end surface 3'b 1 has the function of protecting the exposed metal of the end surface 3'b 1 from corrosion by the contents.

を招くという問題を生じ易い。 In the above-mentioned side joint portion 3', the thickness of the portion 9b1 of the adhesive film layer that is in contact with the end surface portion 3'b1 is usually about 20 to 80 μm, which is very thin, and therefore the inner edge portion 3' Oxygen from the atmosphere enters the can through the score line 7' on b and through the adhesive film layer of portion 9b1 , which tends to cause the problem of deterioration of the contents due to oxidation. Moreover, the moisture inside the can similarly escapes into the atmosphere, which tends to cause the problem of reduced moisture in the contents. In addition, if pores are accidentally generated in the part of the adhesive film layer facing the score line 7' of part 9b1 due to trouble during work, the above tendency will be more remarkable, and in that case, Bacteria can easily enter from the outside and cause the contents to deteriorate.
