Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a synthetic resin bottle body with a handle, in which a synthetic resin bottle body is biaxially stretch-blow-molded by using a separately molded handle as an insert material.

[0002]

2. Description of the Related Art A representative synthetic resin bottle with a large handle, which is constructed by assembling a bottle body and a handle separately molded, is disclosed in Japanese Utility Model Laid-Open No. 63-147429. There is a bottle.

In this bottle of the prior art, a vertically arcuate recess is formed at the rear of the body of the bottle body, and a fitting projection is vertically provided in the center of the recess. The left and right sides of each of the left and right sides are closed to form arc-shaped long grooves, and a frame is constructed as a handle by installing a handle between the upper and lower ends of the arc-shaped front frame plate part. Engagement ridges are provided on both the left and right sides of the plate, and the frame body is forcibly pressed from the rear of the recess to achieve forced overcoming of the engagement ridge on the long groove forming wall, and to the bottle body. The frame is used as a handle so that it cannot be removed.

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

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.

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. The bending deformation weakens the force of engaging and assembling the bottle body and the handle, and there is a problem that the handle is disassembled from the bottle body.

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.

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 sharpened, there is a problem that the engagement of the handle with the bottle body cannot be achieved stably and strongly.

Therefore, the present invention has been invented in order to solve the above-mentioned problems in the prior art, and the occurrence of bending deformation of the engaging assembly portion of the bottle body side with respect to the handle when a load is applied. It is a technical object to suppress the strength and to strengthen the engaging and assembling force of the handle with respect to the bottle body, and thereby to make the assembling of the handle with respect to the bottle body stable and strong.

[0010]

[Means for Solving the Problems]
It consisted of a bottle body and a handle. The bottle body is a synthetic resin biaxially stretch blow-molded product, and the handle is a rear end of an upper holding plate and a lower holding plate located on both upper and lower side surface portions of a recess formed in the rear portion of the body of the bottle body. Parts are connected to the upper and lower ends of the handle plate, respectively, and the assembling convex part is erected from the tip part of the upper holding plate, and the fitting convex part is erected diagonally forward and upward, and the rear part of this upper holding plate A support piece is provided so that the front surface abuts on the body of the bottle body from the end, and the assembly protrusion is hung from the tip of the lower holding plate, and it is fitted diagonally forward and upward from the lower end of the assembly protrusion. The projecting pieces are arranged upright.

Then, the front surface of the support piece of the handle, the tip of the upper holding plate, the convex portion of the assembly, the convex portion of the fitting, the lower surface and the tip portion of the lower holding plate, the protruding piece of the assembly and the protruding piece of fitting are used as insert materials.
The bottle body has an upper holding hole where the tip of the upper holding plate fits, a recess where the fitting convex fits, a fitting recess where the fitting convex fits, and a tip of the lower holding plate fits The lower holding hole, the assembling hole into which the assembling protrusion is fitted, and the fitting hole into which the fitting protrusion is fitted are formed.

It is preferable to set the lateral widths of the assembling convex portion, the fitting convex portion, the assembling projection piece, and the fitting projection piece to be wide.

[0013]

Since the present invention employs the above means, when the bottle main body and the handle are assembled, the front surface of the support piece abuts the upper side surface and the curved portion of the concave portion of the bottle main body, and the lower surface of the lower holding plate is Abutting the lower side surface of the recess, the tip of the upper holding plate is the upper holding hole, the assembly convex is the assembly recess, the fitting projection is the fitting recess,
It is achieved by fitting the lower holding plate tip portion to the lower holding hole portion, the assembling projection piece to the assembling hole portion, and the fitting projection piece to the fitting hole portion.

The load of the bottle that acts on the handle when the handle is lifted is surely supported mainly by the upper surface of the tip of the upper holding plate and the upper surface of the tip of the lower holding plate. Further, the attitude of the bottle main body in this state is also stably maintained by a part of the body of the bottle main body contacting and supporting the front surface of the support piece.

When the bottle body is tilted in order to pour out the contents of the bottle body, a force in the rear lateral direction (a force for pulling the handle out of the bottle body) acts on the handle. The bottle main body is supported by the rear surfaces of the assembling convex portion, the fitting convex portion, the assembling projection piece, and the fitting projection piece, so that the bottle body maintains a stable assembling without being separated from the handle.

In addition, when the contents are poured out, a lateral force in the left-right direction acts on the handle in addition to a lateral force in the front-rear direction. , And the width of the fitting projection piece is set to be wide, the contact area with each bottle main body can be set to be large, thereby more stably supporting. Therefore, the content of the bottle can be surely and easily poured out without rattling the bottle body and while maintaining a good feeling of use.

Further, in the present invention, with the above configuration, the support piece and the assembly projection, the assembly projection and the fitting projection, the lower holding plate and the assembly projection, and the assembly projection are provided. Since the bottle main body is sandwiched between the fitting hole and the bottle main body, a strong assembly can be achieved without the handle coming out of the bottle main body.

In the present invention, since the assembled beam piece that connects the tip of the upper holding portion and the tip of the lower holding portion is not provided in the present invention, not only the handle itself is simplified, but also the molding gold of the bottle body is formed. The mold can be simplified, and it is economical. In addition, along with this, the weight of the handle and the bottle with handle can be reduced, and the handle can withstand large elastic deformation, leading to improvement in strength.
