Description

DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a resin bottle in which the bottom of a bottle is inserted into an opening formed by cutting a cutting wire after the contents of the bottle are consumed, and the shape of a mold for manufacturing the bottle.

2. Description of the Related Art Conventional resin bottles have almost parallel inner diameters from the shoulder to the bottom of the bottle, and have no cut line. We have decided to reduce the volume of time.

[Problems to be Solved by the Invention] In a conventional resin bottle, if a consumer becomes an empty bottle after consuming the contents, if the number of bottles increases in the home, the empty bottle stock space takes up space. Therefore, it was inconvenient until the bottles were collected, and the transportation to the bottle collection place was not heavy when 5 to 6 bottles were transported, but the operation was very inconvenient due to the volume. In addition, the collection company collects the bottles in the form of empty bottles to the collection point, compresses them, and transports them to a recycling factory. In compliance with the Recycling Law, the recycling business has been a problem in terms of collection costs.

An object of the present invention is to improve the inconvenient shape of a conventional resin bottle from a consumer to recycling when the resin bottle becomes an empty bottle. An object of the present invention is to provide a resin bottle and a manufacturing mold shape in which a rear bottle can be inserted and stacked.

[Means for Solving the Problems] In order to achieve the above object, an inclined angle is provided from the shoulder to the lower part of the resin bottle of the present invention, and the diameter of the book is determined by cutting the cut line. Another resin bottle of the invention is a resin bottle that can be inserted and stacked.

[Embodiment of the Invention] An embodiment of the invention will be described based on an embodiment with reference to the drawings. In FIG. 1, a cut line 2 is provided below a shoulder portion 4 of the resin bottle to form a resin bottle having a shape capable of cutting a predetermined position. An inclination angle line 3 is formed in which the inner diameter decreases from the lower part 7 of the cut line guide toward the lower part 5 of the bottle.

In the embodiment shown in FIG.
Are cut line guide convex portion upper 6 and cut line guide convex portion lower 7
The portion between the uncut portions 9 and the uncut portions 9 is provided as a non-cut portion on a part of the cut line.

In the embodiment shown in FIG. 3, the bottle shoulders 4 of the resin bottles, when packed in a cardboard box, come into contact with the bottles to prevent the bottles from sticking. The bottle shoulder 4 is shaped so as to prevent the cut line 2 and the cut line guide projections 6 and 7 from collapsing. An uncut portion 9 is provided in a part of the cut line 2. The diameter of the cut line 2 is made larger than the diameter of the inclination angle 8 to obtain a shape in which another bottle is inserted and overlapped with the same bottle obtained by cutting the cut line 2. The inclination angle portion 3 is provided on the bottle side surface of the bottle bottom 5 from the inclination angle 8 so that the diameter of the bottle bottom 5 is smaller than the diameter of the inclination angle 8. (Fig. 3
The thin portion of the resin bottle body is represented by solid lines only. )

In the embodiment shown in FIG. 4, a cut line 2 is provided between a cut line guide upper 6 and a cut line guide lower 7 at a lower portion of a bottle shoulder 4 on a side die 10 for blow molding a resin bottle from a preform. Is provided. An uncut portion 9 is provided in a part of the cut line 2. The inclined angle portion 3 is provided between the upper inclined angle 8 and the bottle bottom 5 from under the cut line guide 7. (The inclined angle portion 3 is provided up to the bottom mold B.) The inclined angle portion 3 is provided on the side surface of the bottle bottom portion 5 from above the inclined angle 8.
Is provided such that the diameter of the bottle bottom 5 is smaller than the diameter of the upper angle 8. The cut line 2 is cut to form a side mold 10 in a shape that allows another bottle to be inserted and stacked up to the position 13. When the design pattern is applied to the side of the bottle, the design pattern is applied within the parallel line 11 and the inclined angle portion 3, the cut line 2 is cut, and the side mold 10 is shaped so that another bottle can be inserted and overlapped up to the position 12. I do. (Molding blow A.)

In the example shown in FIG. 5, a side die 10 having a shape in which an uncut portion 9 is provided in a part of the cut line 2 is provided. The mating portion of the side mold 10 is located at the position of the sectional lines a and a '.

In the example shown in FIG. 6, a cut-away portion 9 is provided on a part of the cut line 2 in a side mold 8 of a rectangular resin bottle. The mating portion of the side mold 10 is located at the position of the sectional lines a and a '.

In the example shown in FIG. 7, a cut bottle is inserted and overlapped.

[Effects of the Invention] Since the present invention is configured as described above, it has the following effects.

By providing a cut line and a cut line guide above and below the resin bottle, after consuming the contents of the bottle,
Can cut a certain position of an empty bottle.

By providing the uncut portion in a part of the cut line, the upper portion and the lower portion of the bottle do not separate even after securing a new large diameter after the cut.

Another bottle can be cut into the cut bottle and inserted one after another as shown in FIG.

The volume of the inserted empty bottle can be greatly reduced as compared with the volume of the conventional empty bottle.

[0018] The empty bottles that are inserted and saved reduce the storage space for empty bottles in the kitchen at home. Further, at the collection place of empty bottles, the number of empty bottles becomes large, so that there is a great effect of saving storage space and collecting empty bottles in an orderly manner.

In the case of transporting the collected empty bottles to a recycling processing plant, the number of single transports is dramatically increased as compared with transporting in the form of conventional empty bottles, so that the collection cost is large. We can save on width.

By making the shape of the side mold as shown in FIG.
Since the resin bottle of the present invention can be manufactured using a conventional molding machine, the capital investment can be relatively small, so that the conventional equipment can be used efficiently.
