Description

  The present invention relates to a plastic bottle container, and more particularly, to a plastic bottle container having a large capacity provided with a gripping part for gripping the plastic bottle container in a body part.

Plastic bottle containers are used in large quantities as beverage containers for carbonated drinks, fruit juice drinks, mineral water, oolong tea, Japanese tea, and the like. For example, a large capacity plastic bottle container of about 2 liters is also used.
When such a large-capacity plastic bottle container is filled with a liquid, the plastic bottle container becomes considerably heavy due to the weight of the liquid. Therefore, when lifting the plastic bottle container, it is necessary to grip the body of the plastic bottle container with a considerably strong force. In addition, if the force to grip the barrel becomes strong, the container may be deformed or slippage may occur between the hand holding the barrel of the plastic bottle container and the barrel of the plastic bottle container. It was sometimes difficult to lift. In addition, since the plastic bottle container has a large trunk circumference, there is a problem that it is difficult to hold the barrel of the plastic bottle container with one hand.
In addition, in a plastic bottle container having a large capacity, a constricted portion that surrounds almost the entire circumference is formed in an intermediate portion in the height direction of the barrel portion in order to impart necessary strength to the barrel portion. This constricted portion not only functions as a reinforcing portion, but is also provided with a grip portion for hooking a finger of a plastic bottle container (see, for example, Patent Document 1).
Further, as shown in FIG. 1, the plastic bottle container has a front part 11, a back part facing the front part, left and right side parts 13, 13 facing each other, and four sheets connecting the front part 11 and the back part. It is formed in a substantially octagonal shape consisting of the slope portions 14, 14, 14, and 14, and the side surface portions 13 and 13 are provided with arcuate recesses 16. . . 16 forms a continuous waveform, and when the plastic bottle container is gripped, the fingers 31 and 32 are recessed 16. . . A plastic bottle container configured to enter 16 is known (see Patent Document 2).
Furthermore, as shown in FIG. 2, a pair of gripping recesses 6 having a substantially V-shaped cross section are provided in the cylindrical body 3 of the body 5 of the plastic bottle container so as to extend in the vertical direction. The shortest distance between the deepest portions of the recesses 6 is set to 50% or less of the diameter of the body 3, and the reinforcing recesses 6 are provided with three reinforcing beads 12, and the reinforcing beads 12 improve the buckling resistance, There is known a plastic bottle container in which all fingers are fit when a finger is put into the holding recess 6.
