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.

However, in the conventional plastic bottle container as described in Patent Document 1, the thumb and the finger are hooked on the grip part, and the other finger is simply placed from the constricted part of the plastic bottle bottle container to the surface of the trunk part that follows. Since it is held alongside, it has the disadvantages that it is difficult to fit into the palm and difficult to grip.
Further, the plastic bottle containers described in Patent Document 2 and Patent Document 3 are not only invented with respect to a container having no constricted portion, but the plastic bottle container described in Patent Document 2 includes a recess 16. . . By pressing 16, there is a drawback that the slope portion tends to be easily deformed and handling becomes unstable. Further, the plastic bottle container described in Patent Document 3 is invented with respect to a plastic bottle container having a cylindrical body, and cannot be applied to, for example, a plastic bottle having a square body.

In a plastic bottle container having a constricted portion over the entire circumference in a body portion, a pair of concave gripping portions are provided in a part of the constricted portion. Continuing with the gripping part, it extends only in the downward direction in the vertical direction, and is provided with a concave gripping part extension of the index finger, middle finger, ring finger, and little finger, and the gripping part extension is downward. The gist of the present invention is a plastic container which is formed into a tapered shape as it goes on.

According to the present invention, the thumb is hooked on one gripping part, the index finger is hooked on the other gripping part, the middle finger, the ring finger, and the little finger are hooked on the gripping part extension part, and the force of five fingertips is applied to the plastic bottle container. In addition, the plastic bottle container can be firmly held with the crotch portion between the thumb and the index finger along the constricted portion.
Further, since there are five fingertips, it is possible to prevent mistakes such as dropping the plastic bottle container accidentally even when the plastic bottle container is inclined at an angle in order to pour the contents of the plastic bottle container.

Moreover, according to this invention, the holding part extension part is formed in the taper shape as it progresses below . Providing a plastic bottle that can withstand the impact of falling contents filled products and does not buckle due to pressure during pinhole check when manufacturing plastic bottles because the grip extension is formed in a tapered shape. can do.

  In the present invention, the bottom surface of the grip portion and the bottom surface of the grip portion extension can be formed flush with each other. Further, the bottom surface of the gripping portion and the bottom surface of the gripping portion extension portion are not flush with each other, and the bottom surface of the gripping portion is formed to be retracted closer to the center axis of the plastic bottle container than the bottom surface of the gripping portion extension portion. You can also.

The plastic bottle container according to the present invention is a plastic bottle container having a constricted portion over the entire circumference in the body portion, and a pair of concave gripping portions are provided in a part of the constricted portion, and continuously downward in the vertical direction. A concave gripping part extension that extends only on the index finger, middle finger, ring finger, and little finger is provided continuously , and is formed into a tapered shape as the gripping part extension progresses downward. Therefore, hook the thumb on one gripping part, hook the index finger on the other gripping part, hook the middle finger, ring finger, little finger on the gripping part extension, and give the force of the five fingertips to the plastic bottle container, In addition, the plastic bottle container can be firmly held with the crotch portion between the thumb and the index finger along the constricted portion.
