【発明の詳細な説明】
この発明は形状が不均一（興なる）の中空箱体の成形方
法に諷するもので、従来硬質性の合成樹脂製品の不均一
の中空箱体は多種多様の広範囲に使用されているが、こ
の合成樹脂の中空箱体の成形方法も又多く知られている
ところである。[Detailed Description of the Invention] This invention is based on the method of molding hollow boxes with non-uniform shapes. However, many methods for molding hollow boxes made of synthetic resin are also known.
代表的な１ものとして、射出成形、押出成形、ブロー成
形、真空成形等が特に周知であるが、小型の中空箱体は
射出成形や押出成形で半分ずつ成形したものを２個接着
剤にて後着したものが多（、又大啜の中空箱体はブロー
成形で一発で成形するものが多い。Injection molding, extrusion molding, blow molding, vacuum forming, etc. are particularly well-known as typical methods, but small hollow boxes are made by molding two halves using injection molding or extrusion molding, and then attaching them with adhesive. Many of them arrived later (also, many of the hollow boxes for large sake bottles are molded in one shot using blow molding.
ところで、射出成形、押出成形による２個の半成形体を
接着剤にて接着して１個の空成した中空箱体にするもの
に於いては、接着剤による作業は作ａｍ境や会書の関係
で安全衛生上問題がある。By the way, in cases where two semi-molded bodies made by injection molding or extrusion molding are glued together to form a single hollow box, the work with adhesive is not allowed in the manufacturing environment or in the conference manual. There are health and safety issues related to this.
更に不均一な形状でしかも小型の中空箱体をブロー成形
するには全体が均一な板厚が得られず強度的に開−があ
り、しかもブロー成形機は大型で且つ橿そのものが複雑
でコストアップとなる欠点を有する。Furthermore, when blow molding a small hollow box with a non-uniform shape, it is not possible to obtain a uniform board thickness throughout, resulting in a gap in terms of strength.Moreover, the blow molding machine is large and the handle itself is complicated, making it costly. It has the disadvantage of increasing.
そこで、この発明は上記１ＩｉＩを解消するべき方法と
して接着剤をやめて合成樹脂を成形型に注入して２個の
形状の興なる半成形体を型の中で一体化し、更にブロー
成形でな（、射出成形や押出成形で成形するので肉厚も
均一で強度的にも問題なく、しかも安価な形状が不均一
の中空箱体を提供することにある。Therefore, as a method to solve the above-mentioned problem 1IiI, this invention eliminates the adhesive and injects synthetic resin into the mold, integrates the two semi-shaped semi-molded bodies in the mold, and further blow molds ( The object of the present invention is to provide a hollow box body having a uniform thickness, no problem in terms of strength, and having a non-uniform shape, which is formed by injection molding or extrusion molding, and which is inexpensive.

An elongated groove portion 5 is projected at a position corresponding to the upper lid 2, and a flange-like abutment portion 6 is provided around the entire circumference of the upper end so as to match the abutment portion 3 of the upper semi-molded body 1, Furthermore, a plate-shaped attachment part 9 is provided, in which a tube part 7 is suspended downward from the end of the elongated groove part 5, and a plurality of regular sizes 8 are connected to the Tm of the elongated groove part 5 and the lower part of the elongated groove part 5 side of the semi-formed body 4.
are integrally molded.
前記各半成形体１．４ を一体にして中空箱体１０ と

なるような事も解消され且つ安価に蝿供できる。In summary, the present invention stores a plurality of individually molded semi-molded bodies having different shapes in a mold while abutting each other, and the mold forms a concave sound on the outer periphery corresponding to the abutting portion of each semi-molded body. By injecting synthetic resin into the recess and integrally connecting each half-molded body, it is possible to create a small medium-sized medium whose shape is uneven.
The box body is removed using an adhesive that poses a risk of pollution and health and safety concerns.
'It can be manufactured into a product, and since a large-scale blow molding machine is not used, molding is easy. Of course, problems such as uneven wall thickness and weak strength can be eliminated, and flies can be provided at low cost.
