Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a structure of a plastic bottle containing drinking water or alcoholic beverage, and more particularly to a structure of a plastic bottle suitable for loading or storing plastic bottles.

[0002]

[Prior art]

 Traditionally, sake has been sold in retail stores in a single bottle, but the above-mentioned bins cannot be stacked on display shelves, and there is the disadvantage that sales efficiency is poor. In addition, when carrying the product, it was carried using a carrying box or the like, but there was a defect that the efficiency of the carrying was poor because the capacity of the bin was smaller than the capacity of the box.

[0003]

[Problems to be solved by the device]

 The present invention has been made in view of the above points, and its purpose is to make it possible to effectively use the narrow sales space of a store, and further, to provide a new plastic bottle with good transport efficiency. Is to provide the structure of.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the structure of the plastic bot of the present invention is such that a plastic bottle molded by blow molding is formed into a quadrangular shape at the top and bottom, and is positioned at the center of the ridge near the four ridges at the bottom. , A stepped portion is formed at the upper end portion, an opening is provided therein, and at least three convex portions for fitting into the recessed portion formed at the bottom portion of another plastic bottle are provided, and The head of the lid of the opening provided at the upper end is arranged below the surface of the upper end.

In addition, a plastic bottle molded by blow molding is formed into a square shape at the upper end and the bottom, and a step is formed at the upper end to form an opening therein, and a convex shape formed in a cross shape. And a cross-shaped concave portion, into which a cross-shaped convex portion formed on the upper end portion of another plastic bottle is inserted, and a head portion of the lid of the opening is formed from a surface of the upper end portion. It is characterized in that it is configured to be on the lower side.

According to this invention, a plastic bottle having a substantially prismatic shape is molded by blow molding, an opening is formed at the upper end of the plastic bottle, a convex portion is provided at the upper end, and a concave portion is provided at the bottom. It is a thing. In this way, when the plastic bottle itself is loaded and stored by providing the convex portion and the concave portion on the upper end portion and the lower portion of the plastic ball respectively, when the convex portion of the upper end portion is stacked on the bottom portion of another plastic bottle, Since it fits into the recessed part and can be loaded stably, it is possible to carry a large number of plastic bottles efficiently, and it is also possible to effectively use the space when storing plastic bottles. Furthermore, even in the case of display at a store, the space of the store can be effectively utilized.

[Embodiment of device]

 An embodiment of the structure of the plastic bottle according to the present invention will be described with reference to FIGS. 1 to 4 are diagrams showing a first embodiment. In the figure, 1 is a plastic bottle produced by blow molding, 2 is an upper end of a plastic bottle 1 formed in a square shape (for example, square), 3 is a cross-shaped convex portion formed on an upper end 2, 4 is an upper end 2. A step portion 5 in which a part of the step is formed in a paragraph shape to provide an opening portion is an opening portion formed in the step portion 4, and a lid 5a is attached to the opening portion 5. Reference numeral 6 is a cross-shaped recess or groove provided in the bottom portion 7 of the plastic bottle 1.

The plastic bottle 1 may be formed as a container for various kinds of alcoholic beverages, orange juice, mineralane water, bird dragon tea, or the like. The plastic bottle 1 is formed by blow molding of a known vinyl resin material or the like. It is done. The cross-shaped convex portion 3 formed on the upper end portion 2 of the plastic bottle 1 is molded in such a size that it can be fitted into the concave portion 6 formed on the bottom portion 7 of another plastic bottle 1 when the plastic bottle 1 is loaded. It

When the lid 5a of the opening 5 is attached, the head 5b of the lid 5a is formed so as to be lower than the surface of the upper end 2 of the plastic bottle. The upper end 2 of 1 and the bottom 7 of the other plastic bottle 1 are stacked in close contact with each other, and as described above, the convex portion 3 of the upper end 2 and the concave portion 6 of the bottom 7 are fitted to each other for stable stability. It becomes possible to load.

As described above, the plastic bottle 1 in which the cross-shaped convex portion 3 and the cross-shaped concave portion 6 are fitted to each other and the upper end portion 2 and the bottom portion 7 are closely attached to each other is filled in the plastic bottle 1. The weight exerts a pressing force from the upper side to the lower side, and further, the cross-shaped convex portion 3 and the concave portion 6 prevent the lateral shift to the left and right, and the stack is performed.

The concave portion 1a provided on the side surface of the plastic bottle 1 is a rib provided to maintain the strength of the plastic bottle 1. Also, as shown in FIG. Reinforcing ribs 7a and 7b are formed to prevent distortion when alcohol is put in the plastic bottle 1.

FIG. 5 shows a second embodiment of the present invention. Like the plastic bottle of FIGS. 1 to 4, the upper end 12 and the bottom 17 of the plastic bottle 11 are square (in the embodiment, Square) and is located near the four ridges 17a, 17b, 17c, 17d of the bottom 17 and in the center of the ridges 17a, 17b, 17c, 17d for positioning. Is provided, and at least three convex portions 13, 13, 13 for fitting into the concave portions 18, 18, 18, 18 are provided in the upper end portion 12 at positions corresponding to the concave portions 18. It is sufficient that at least three convex portions 13 are provided, and the concave portion may be formed as a cross-shaped concave portion or groove.
