に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a method of forming a glass product having one or more concave portions on a part of its outer surface by round blowing.
（従来の技術）
従来から、割金型である仕上型の合い目の痕跡のない美
しい外表面を有する中空ガラス製品の成形方法として、
回し吹き成形方法は周知である。(Prior art) Traditionally, as a method for forming hollow glass products that have a beautiful outer surface without any traces of joints in the finishing mold, which is a split mold,
Round blow molding methods are well known.
ところが、従来の回し吹き成形方法においては、第３図
に示すような外側面の一部に１個若しくは２個以上の凹
状部２を有するガラス製品１の成形は不可能であった。However, in the conventional rotary blow molding method, it was impossible to mold a glass product 1 having one or more concave portions 2 on a part of its outer surface as shown in FIG. 3.

その結果として生産コストも高くなるという欠点もあっ
た。Therefore, as disclosed in Japanese Utility Model Publication No. 59-10090, a pressing mold for forming a concave portion on the outer surface of a preformed glass product has been developed, but in this case, secondary processing is required. Because it is a molding method, there are problems such as not being able to handle mass production and requiring labor for secondary processing.
As a result, there was also the disadvantage that production costs increased.

成することを特徴とするものである。(Means for Solving the Problems) The present invention provides a rotary blow molding method for hollow glass products in which a parison suspended by a neck ring is rotated and blow molded in a finishing mold, in which the parison is suspended at the final stage of the blow molding process. By stopping the rotation of the neck ring and advancing and retracting one or more pins provided in the finishing mold, one or two pins are attached to a part of the outer surface of the glass product. It is characterized by forming more than one concave portion.

外側面の一部に４個の凹状部２を形成することとなる。The parison 4 molded in the parison molding process (2) is suspended by a neck ring 5 and transferred to the blow molding process (2), which consists of a finishing mold 6 and a bottom mold 7 (see FIG. 1(A)). After that, as shown in FIG. 1(B),
A blow head 8 is placed on the upper part of the neck ring 5, and the parison 4 is rotary blow-molded in the finishing die 6 while blowing air. Up to this stage, the process is similar to the conventional rotary blow molding process, resulting in a hollow glass product with a beautiful outer surface without any traces of the finished mold joints. Furthermore, in the final stage of the blow molding process, as shown in FIG. Four concave portions 2 are formed.

程へと進むこととなる。That is, as shown in FIG. 2, first, the rotation of the neck ring 5 is stopped (step 2), and after a slight delay, the cylinder 9 is activated (step Φ). To operate the cylinder 9, timing air enters from the cylinder head 10 through piping (indicated by a broken line) in the finishing die 6, presses the cylinder plunger 11, and the plunger 11 advances into the finishing die 6 to produce the glass product. Four concave portions are formed in a portion of the outer surface of the tube. After that, the timing air ran out and the plunger 11
is retreated to its original position by the coil spring 12, and the glass product is taken out from the take-out position To and proceeds to the next process.
この後工程として、上方部分（一般にモイルと称される
