けて構成されている。In this bottle, a concave portion having an arcuate shape is formed at the mouth of the body portion of the bottle body, and a fitting protrusion is vertically provided in the center of the concave portion. A frame as a handle is constructed by vertically arranging arc-shaped long grooves with both ends closed on both sides, and a handle is installed between the upper and lower ends of the arc-shaped front frame plate, and the front frame plate of this frame is formed. By attaching engaging ridges on both left and right sides of the frame and forcibly pressing the frame from the rear of the recess, the engaging ridges can be forced over the long groove forming wall, and the handle can be gripped against the bottle body. It is constructed by assembling the frame body as.

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不都
合がある。The above-mentioned bottle body can achieve a firm attachment of the handle to the bottle body. However, since a strong work force is required to attach the handle to the bottle body, it is dedicated to the attachment of the handle to the bottle body. This requires equipment, which increases the manufacturing unit price, and the bottle body is a biaxially stretch blow-molded product, so the wall thickness is thin, so a strong work force is required to assemble the handle to the bottle body. If it works, there is a risk that this bottleneck body may be deformed, such as buckled, due to this work force.
There is an inconvenience that a defective product may occur when the handle is attached.

力な係合力を得ることが難しいと云う不都合があった。Further, the holding of the assembled state of the handle with respect to the bottle main 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 long engaging groove. Since it is achieved by forcibly overcoming the wall portion, the protrusion height of the engaging projection and the groove forming wall portion, that is, the size of the engaging force exerting portion is limited to the range where the above-mentioned overcoming can be achieved. Therefore, there is a disadvantage that it is difficult to obtain a sufficiently strong engaging force.

組付きが不安定となり、把手を持っての取扱いが不安定
となると云う不都合があった。Further, the bottle body and the handle are molded separately, and the bottle body is a biaxially stretch blow molded product, whereas the handle is an injection molded product, so that they are engaged with each other. Since there is a large difference in the molding dimensional accuracy of the part, it is difficult to make the engagement assembly between the bottle body and the handle without rattling, and this rattling makes the assembly of the handle on the bottle body unstable. However, there was an inconvenience that the handling with the handle became unstable.

部分を成形すると云う手段が提案されている。As a conventional technique for solving this inconvenience, a portion of the bottle main body is made of an insert material with an engaging assembly portion of the handle.
A means has been proposed in which the engaging assembly portion of the bottle body is molded by axial stretch blow molding.

と云う利点を有している。According to this prior art, the attachment of the handle to the bottle body can be achieved without difficulty, the assembly of the handle to the bottle body can be achieved without rattling, and the handle to the bottle body can be formed at the same time when the bottle body is molded. It has the advantage that assembly can be achieved.

薄くなって機械的強度が不足すると云う問題があった。However, in the above-mentioned prior art, since the bottle body is a biaxially stretch blow-molded product, the bottle body is stretch-molded using the engaging assembly portion of the handle as an insert material. There has been a problem that the portion with the combined assembly is in a locally stretched state and the thickness of the portion with the engaged assembly of the molded bottle body is extremely thin, resulting in insufficient mechanical strength.

揮することができないと云う問題があった。Further, the engaging assembly portion of the bottle body is biaxially stretch-deformed to some extent and then stretch-formed into the final shape, like the other portions of the bottle body, so that the moldability is not sufficient. Therefore, there is a problem in that a strong and stable engaging and assembling force cannot be exerted.

ことを目的とする。Therefore, the present invention has been invented in order to solve the above-mentioned problems in the prior art. The engaging assembly portion of the bottle body is stretch-molded using the engaging assembly portion of the handle as an insert material. A technical object is to increase the wall thickness to a sufficient value and to improve the moldability, so that the purpose of the present invention is to safely and reliably obtain a strong and stable assembly of the handle to the bottle body.

A bottle-shaped bulging piece protrudingly provided on the bottle body, and an engaging groove formed between the bulging piece and the bottom surface of the concave portion; and a tip surface that comes into contact with the bottom surface of the concave portion of the bottle body. A handle plate is integrally provided between the upper and lower ends of a pair of assembled beam pieces arranged in parallel, and engaging projecting pieces that engage with the engaging grooves of the bottle body are provided on the opposing surfaces of both assembled beam pieces. A method of forming a bottle with a handle fixedly attached to the handle, wherein both engaging protrusions of the handle have a center angle of about 90 degrees with respect to the center axis of the biaxial stretching blow molding of the bottle body. The bottle body should be placed in a position, and in this state, by using the beam piece with the handle and the engaging projection piece as an insert material, the bottle body is biaxially stretch-blow-molded so that the bottle body is engaged. Shaping the groove, in.

の凹部底面に突設するのが有効である。A beam piece with a handle assembly is used as an insert material,
It is effective to provide a pressing strip that comes into contact with the outer surface of the assembled beam piece so as to project from the bottom surface of the concave portion of the bottle body.

になる。Since the bottle body is biaxially stretch blow-molded by using the beam piece with the handle and the engaging projection piece as the insert material, the bulging piece and the engaging groove of the bottle body, that is, the engaging assembly of the bottle body is attached. The portion is stretch-molded with the assembled beam piece and the engaging projection piece that are the engaging assembly portion of the handle as a part of the molding die surface.

フォームに対して、径方向に沿って充分に接近して位置
する。When the engaging assembly portion of the bottle body is stretch-molded, both the engaging protrusions of the handle that function as insert materials are substantially with respect to the center axis of the bottle body for biaxial stretch blow molding. The preform, which is the primary molded product of the bottle body, is located at the central angle of 90 degrees, and both of these engaging projections are located on the bottom surface of the recessed portion of the bottle body to be molded. In contrast, they are located sufficiently close to each other in the radial direction.

部分に成形される部分は、充分に延伸変形しない状態、
すなわち肉厚が大きくかつ成形性が良い状態で両係合突
片に接触することになる。For this reason, during biaxial stretch blow molding of the bottle body, the portion of the bottle body to be formed on the engaging assembly portion must contact both the engaging projections, which are insert materials, at the initial stage of the stretching deformation. As a result, the portion of the bottle body formed into the engaging assembly portion is in a state in which it is not sufficiently stretched and deformed,
That is, the engaging projections come into contact with each other in a state where the wall thickness is large and the moldability is good.

後の局部的な延伸変形による係合組付き部分への延伸成

係合組付き部分に延伸成形されることになる。As described above, since the portion of the bottle body that is formed into the engaging assembly portion comes into contact with both the engaging protrusions as the insert material in a state where the thickness is large and the moldability is good, the portion after the contact is contacted. When stretch-molding the engaging assembly portion by local stretching deformation, the engaging-assembly portion is stretch-molded with a relatively sufficient thickness and with good moldability.

成形されることになる。Further, since both engaging protrusions are located at a central angle of approximately 90 degrees with respect to the center axis of extension of the bottle body, the engaging protrusions are extended to the bulging piece as part of the molding die surface. The preform part to be molded has a stretching direction of approximately 45 with respect to the radial direction.
Therefore, it is possible to smoothly wrap around the rear surface of the engaging protrusion, which is the molding die surface, that is, the engagement surface side with the bulging piece to be molded, and thereby the engagement on the bottle body side. Stretch molding of the bulging piece, that is, the engaging groove, which is the fitting-attached portion can be smoothly and reliably achieved, and the engagement-attached portion having a strong engaging force is formed.

条９が膨出状の突設されている。On the bottom surface 4 of the recess having the vertical projection 5, the engaging assembly portion on the bottle body 1 side is stretch-molded by using the engaging assembly portion of the handle 10 which is injection-molded in a predetermined shape in advance as an insert material. Has been done. That is, vertical ridge-shaped bulging pieces 6 are projected on both side projecting end sides of substantially the upper half of the vertical bulging portion 5, and by the bulging of the bulging pieces 6, the bulging pieces 6 and An engaging groove 7 having an upper end abutting 8 is formed between the concave bottom surface 4 and the concave bottom surface 4 portion near the vertical projection 5 side. A pressing strip 9 that abuts against the side surface is provided in a bulging shape.

する。The pressing strip 9 is a handle 1 attached to the bottle body 1.
It suffices to contact the outer surface of the beam member 12 with both sets of 0, and even if the structure is such that it simply bulges and protrudes in the form of vertical ridges, a plurality of protrusions are spaced apart. May be arranged vertically, and abut on the outer surface of the paired beam pieces 12 of the handle 10 assembled to the bottle body 1 so that the two paired beam pieces 12 widen the distance from each other. It functions to prevent the deformation in the direction (the deformation of the assembling beam piece 12 weakens the engaging assembling force of the tip 10 with respect to the bottle body 1).

The rear surface of the bottle body 1 is a flat surface perpendicular to the parting line PL (see FIG. 3) of the biaxially stretch blow molding die of the bottle main body 1, and thus the bulging piece 6 is stretch-molded. While smoothly wrapping around the 1 '(see FIG. 3) portion of the engaging projection piece 14 to the rear surface side, the repulsive force of the engaging force acting between the engaging projection piece 14 and the bulging piece 6 is achieved. The vector component force acting in the outward direction that deteriorates the engagement between the engagement protrusion 14 and the bulging piece 6 is less likely to be generated.

The preform 1 ', which is located sufficiently close to the preform 1', is formed in the engaging assembly portion of the bottle body 1, so that the engaging projection 14 is formed at the beginning of the stretching deformation. The end portion of the bottle is brought into contact with the front end portion of the bottle, and is locally stretched and deformed as it is to be molded into the engaging assembly portion of the bottle body 1.
