Abstract

PROBLEM TO BE SOLVED: To reduce the occupying space, and reduce the costs for the storage until a content fluid is filled, and the transport or the like by capacity-reduce-deforming the whole body, excepting the mouth section, of a thin bottle made of a synthetic resin, which is blow-molded, into a flat shape in a manner to be restorable to the original shape, and handling the flatly deformed capacity-reduced bottles by stacking a large number of them. SOLUTION: A thin bottle made of a synthetic resin, which is formed by a blow-molding means or the like into a bottle of a thin thickness, is constituted in such a manner that at the upper end of a cylindrical body section 2 having a bottom section 5, a cylindrical mouth section 4 is erected and connected to through a shoulder section 3. In this case, by pressing the body section 2 of the thin bottle in the lateral direction, the body section 2 and the shoulder section 3 are crushed and deformed. At the same time, the bottom section 5 is rotated in the vertical direction, and the whole body excepting the mouth section 4 is capacity-reduced into a flat shape. Then, a large number of the capacity-reduced bottles 1a, which are capacity-reduced into the flat shape, are superposed in the lateral direction, and housed in a corrugated fiber board box 6 or the like, or bound, and thus, the handling such as the storage or the transport is performed. By this constitution, the costs for the storage until a content fluid is filled, and the transport are reduced, and at the same time, the efficiency of the handling work is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of handling a synthetic resin thin-walled bottle in a process from molding to filling of a content liquid.

[0002]

2. Description of the Related Art As containers for various liquid contents, thin bottles made of synthetic resin which are formed sufficiently thin by blow molding means or the like are frequently used.

[0003]

However, this synthetic resin thin-walled bottle has the advantage of being lightweight, but is bulky and occupies a large space. In the process from delivery to the manufacturer and filling with the content liquid, there has been a problem that the storage cost and the transportation cost are high, and the handling is troublesome.

Accordingly, the present invention has been made to solve the above-mentioned problems in the prior art, and is intended to reduce the volume of a synthetic resin thin-walled bottle in the process from molding to filling with a content liquid. It is another object of the present invention to reduce the space and cost of storage and transportation, and to facilitate the handling in a filling line.

[0005]

Means for Solving the Problems The present invention for solving the above technical problem is to make the entirety of a blow-molded synthetic resin thin-walled bottle except for the mouth flat and easy to return to its original shape. It is to reduce the volume, and to handle a large number of the flattened volume reducing bottles.

A synthetic resin thin-walled bottle molded by a container maker is reduced in volume in a flat shape, and a large number of the flattened volume-reduced bottles are handled in piles. Therefore, the cost of storage, transportation, and the like in the process until the content liquid is filled can be reduced, and the handling in the filling line can be easily performed.

[0007] The volume-reduced bottle is easily and smoothly returned to the original bottle shape by injecting and filling the content liquid or swelling with air in a product manufacturer, and is supplied to the product. You.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. Examples of the synthetic resin thin bottle 1 suitable for carrying out the present invention include polyethylene terephthalate, polypropylene, polyethylene naphthalate,
Synthetic resin material such as cyclic polyolefin resin weight 0.0
It is preferable that the material is thin-walled by biaxial stretch blow molding so as to have a thickness of 04 to 0.025 g / ml.

As shown in FIG. 2, the bottle 1 is formed with a thread on the outer peripheral surface thereof through a shoulder 3 whose diameter is gradually reduced upward at the upper end of a cylindrical body 2 having a bottom 5. The cylindrical mouth 4 is provided in a standing manner.

In the embodiment of the present invention, as shown in FIG.
The shoulder 5 and the shoulder 3 are crushed and deformed, and the bottom 5 is rotated in the vertical direction to reduce the volume except the mouth 4 to a flat shape.

Next, the large number of flattened volume-reduced bottles 1a are stacked in a horizontal direction and stored in a cardboard box 6 or the like (see FIG. 1), or bound and stored. It handles handling such as transportation.

As shown in FIG. 3, the bottle 1 may be deformed to be flat in the vertical direction as shown in FIG.

The synthetic resin thin bottle 1 according to the present invention.
It is necessary that the bent portion formed on the body portion 2 or the like does not whiten so that it is noticeably conspicuous during the volume reduction deformation,
In addition, product manufacturers inject the content liquid into volume-reducing bottles,
It is also necessary to smoothly return to the original shape of the bottle 1 by filling, and selection of a material and setting of the thickness and the like satisfying these conditions shall be appropriately performed.

[0014]

Since the present invention has the above-described structure, the following effects can be obtained. The thin bottle made of synthetic resin molded by a container maker is reduced in volume in the horizontal direction and deformed, and a large number of the flattened volume-reduced bottles are handled in a stack in the horizontal direction. Can be greatly reduced, thereby reducing the cost of storage, transportation, etc. in the process until the content liquid is filled, and can be easily handled, and the efficiency of the handling operation can be increased. Can be achieved.
