った。DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
Although it is possible to achieve a strong attachment of the handle to the bottle body, a strong work force is required to attach the handle to the bottle body, so special equipment is required to attach the handle to the bottle body. There was a problem that the unit price would be high.

より壜本体に座屈変形等の不正変形が発生する恐れがあ
り、把手の取付け時に不良品を生じる場合があるという
問題があった。Since the bottle body is a biaxially stretch blow-molded product, its wall thickness is thin. Therefore, when a strong working force acts to attach the handle to the bottle body, this acting force causes the bottle body to move. There is a possibility that an improper deformation such as a buckling deformation may occur, and a defective product may be produced when the handle is attached.

う問題があった。Since the bottle body is a biaxially stretch blow-molded product, its wall thickness is thin, so that elastic bending deformation easily occurs due to the load at the engaging assembly portion with the handle. Due to the bending deformation, the force of engagement between the bottle body and the handle is weakened, and there is a problem that the handle is disassembled from the bottle body.

易く、このため把手を持っての壜体の取扱いが不安定と
なる場合があるという問題があった。Further, the holding of the assembled state of the handle with respect to the bottle body is achieved only by fitting the engaging projection to the long groove, and the fitting of the engaging projection to the long groove is achieved by forming the engaging projection with the long groove. Since it is achieved by forcibly overcoming the wall, rattling is likely to occur in the attachment of the handle to the bottle body, which may make the handling of the bottle with the handle unstable. There was a problem.

た。Furthermore, the bottle main body and the handle are separately molded, and the bottle main body is a biaxially stretch blow molded product, whereas the handle is an injection molded product, and therefore the mutual relationship is maintained. Since there is a large difference in the molding dimensional accuracy of the mating part, it is difficult to make the engagement assembly between the bottle body and the handle free of rattling, and at the same time on the bottle body side which is a biaxially stretch blow molded product. Since the degree of protrusion of the mating portion cannot be made sharp, there is a problem that the engagement of the handle with the bottle body cannot be achieved stably and strongly.

It is a technical issue to eliminate it, and the purpose is to make the attachment of the handle to the bottle body stable and strong.

とにより達成維持される。[Function] When the handle is attached to the bottle body, the vertical projection provided on the bottom surface of the recess of the bottle body is used. It is achieved and maintained by engaging with the engaging groove in a state of being locked to the piece, holding the same from both sides, and fitting the fitting projecting piece of the handle to the fitting hole of the bottle body.

いる。When the handle is attached to the bottle body, the attachment of the handle to the bottle body is such that the engaging protrusion of the handle engages with the engagement groove of the bottle body, that is, the expansion of the bottle body. The engagement of the engaging projection with the engaging groove is maintained by the engagement of the engaging projection of the handle with the engaging hole of the bottle body. The fitting between the piece and the fitting hole portion prevents the grip from being displaced with respect to the bottle body in a state where the engaging projection is engaged with the engaging groove.

る。That is, when the handle-side fitting protrusion is fitted into the bottle-body-side fitting hole, the bending deformation of the bottle body, which specifically weakens the engagement of the handle with the bottle body, Prevents the deformation of the bottom surface of the concave portion provided with the vertical protrusion in the direction of narrowing the horizontal width of the vertical protrusion, thereby stably maintaining the engagement between the engagement protrusion and the engagement groove. , Similarly, the bending deformation of the beam pieces with both sets of the handle that weakens the engagement assembly of the handle with the bottle body, specifically, the bending deformation of the beam pieces with both the sets in the direction of expanding the mutual interval occurs. The engagement between the engagement protrusion and the engagement groove is stably maintained by preventing the engagement.

されることになる。Biaxially stretch-blow molding the bottle body by using the beam piece with both sets of the handle, the tip end surface of the beam piece with the assembly, the engaging projection piece, and the fitting projection piece as insert materials.
The bulging piece, the engaging groove, and the fitting hole, which are the part of the bottle body that engages with the handle, are the beam part with both sets of the handle, the tip surface,
The engaging protrusion and the fitting protrusion are assembled and molded with substantially no space.

の機械的な不正変形の発生することがない。Since the attachment of the engaging assembly portion of the bottle body to the handle is achieved by stretch molding of the engaging assembly portion of the bottle body, the portion of the bottle body is locally stretched and deformed. However, there is no rigid and unreasonable elastic deformation. Therefore, when the handle is attached to the bottle body, the bottle body, which is a biaxially stretch blow-molded product, is mechanically deformed such as buckling deformation. Does not occur.

る。Further, the engaging assembly portion of the bottle body is assembled to the handle by the molding accompanying the biaxial stretching blow molding of the bottle body, so that the assembly of the handle after the molding and the biaxial stretching. It is possible to set the degree of protrusion of the engaging portion to such an extent that a sufficiently strong engaging force can be exerted without considering the release from the blow molding die device.

つ確実に維持する。By fitting the fitting protrusion of the handle to the fitting hole of the bottle body, the bending of the portion of the bottle body engaging with the engaging assembly with respect to the portion with the engaging assembly of the handle is weakened. Displacement due to deformation and displacement due to flexural deformation in the direction that weakens the engagement assembly of the beam pieces with both grips of the handle are strongly and reliably prevented, and a strong engagement assembly of the handle with the bottle body is provided. Is stably maintained, so that the strong engagement of the handle with the bottle body is firmly and reliably maintained over a long period of time.
【0030】把手の嵌合突片は、単に組付き梁片の先端
面に突片を突設しただけの構成であるので、その構造が
極めて簡単であり、もって実施が容易である。Since the fitting projection of the handle has a structure in which the projection is simply provided on the tip end surface of the assembled beam piece, its structure is extremely simple and therefore easy to implement.

係合組付き部分に座屈変形等の剛的な永久変形とか不正
変形の発生する恐れが全くなく、もって壜本体に対する
把手の安全で良好な係合組付けを達成できる。When the portion of the handle with which the engaging assembly is assembled is made of an insert material, the assembly of the handle with respect to the bottle body is achieved at the same time when the bottle body is biaxially stretch blow molded, so that the bottle body is a separate molded product. Since there is no possibility that rigid permanent deformation such as buckling deformation or improper deformation will occur at the engagement assembled part of the bottle body due to the engagement assembly of the handle and the handle, the handle is safe for the bottle body. Good engagement assembly can be achieved.

る。The biaxial stretch blow molding of the bottle main body as an insert for the handle can be carried out by slightly modifying the existing biaxial stretch blow molding apparatus for molding the bottle main body,
Therefore, it is possible to prevent a large increase in cost for implementation.
