Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a synthetic resin bottle body, and more particularly to a cylindrical wall structure of a body portion of a large bottle body which is biaxially stretch blow molded.

[0002]

2. Description of the Prior Art Bottles made of synthetic resin, especially large bottles made of synthetic resin, are easy to mold and suitable for mass production, have excellent resistance to contents, have high mechanical strength, and can be stored. It is widely used in a wide range of fields as a liquid storage container because it is light in weight for its volume.

As described above, the synthetic resin bottle has many excellent characteristics, but since the surface is smooth and slippery, and the thickness of the main body is thin, When gripping and handling, there is a disadvantage in that the part that the fingertip touches is bent and deformed, and the gripping and handling tends to be unstable.

In order to eliminate this inconvenience, in the conventional bottle of this kind, a separately molded handle body is assembled and fixed to the bottle body, or the left and right portions of the latter half of the bottle body are fixed. The recessed portion is formed by being recessed, and the bottom surface portion of this recessed portion and the barrel wall portion of the latter half portion form a grip portion that can be easily gripped with one hand.

[0005]

Among the above-mentioned conventional techniques, the means for forming the handle portion by providing the recessed portion in the rear half of the bottle body is easy to mold and can be manufactured at low cost. Although it has the advantage that it can be done, since the depressed portion forming the handle portion is strongly visible as the appearance of the bottle, there is a problem that the appearance of the bottle is not always good.

Further, since the handle portion is formed in the latter half portion of the bottle body, the bottle is given directionality. Therefore, when the label is attached to the bottle body or the bottle is lifted. In such cases, it is necessary to set or confirm the posture of the bottle body along the circumferential direction, and there is a problem that handling of the bottle becomes troublesome.

Therefore, the present invention was devised in order to solve the above-mentioned problems in the prior art, and makes the fingertip of one hand lightly gripping the bottle body sufficiently catch on the surface of the bottle body. This is a technical issue, and an object thereof is to make it easy to handle with one hand, in a stable state.

[0008]

Means for Solving the Problems The means of the present invention for solving the above-mentioned technical problems is a recessed recess formed in a body portion having a bottomed cylindrical shape, which is opposed to the front and rear of a substantially central height position. Having both, the both recesses have a height width and a lateral width in which the fingertip of one hand holding the torso can intrude with a sufficient margin, and have a depth in which the intruding fingertip can be strongly caught. It is in.

It is preferable that both the concave portions are arranged with the central axis of the body portion as an axis of symmetry, and the body portion has a rectangular cylindrical shape with a bottom.
It is effective to provide a recess in the long side tube wall portion of the body portion, and further, a central peripheral groove for reinforcement is provided at a substantially central height position of the body portion, and a part of the central peripheral groove is formed. It is effective to provide the recess in a shared configuration.

[0010]

[Operation] The central portion of the body of the bottle is grasped with one hand in such a manner as to be sandwiched from the front-rear direction. When the body part is gripped by the one hand, the fingertips of the one hand, specifically, the thumb and the index finger of the forefinger or the middle finger are gripped in a form in which they are intruded into both recesses.

Since the concave portion has a height width and a lateral width which allow a fingertip to intrude with a sufficient margin, the intrusion of the fingertip into the concave portion can be easily and surely caused by an instantaneous tactile sensation. Can be achieved.

When the bottle body is lifted with the fingertip intruding into the concave portion, the load of the bottle body tends to cause a slip between the fingertip and the surface of the bottle body. Since the depth is such that it can be caught,
The fingertip that has entered the concave portion is caught on the peripheral portion of the concave portion with sufficient strength to overcome the load of the bottle body, whereby the lifting operation of the bottle body with one hand can be achieved in a stable state.

Since both the recesses are recessed in such a size that the fingertips can enter with a sufficient margin, the ratio of the size of these recesses to the entire outer surface of the body of the bottle is extremely small. Therefore, the depressed form of the concave portion does not stand out as the appearance of the bottle.

Further, since the both recesses only form a simple small depression on the surface of the body of the bottle, the recesses rarely specify the directionality of the bottle.

[0015]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. The bottle 1 of the illustrated embodiment is a large-sized biaxially stretch blow molded bottle made of polyethylene terephthalate resin,
On the upper end of the body portion 2 having a rectangular shape with a bottom, a short cylindrical mouth portion 6 having a thread formed on the outer peripheral surface is integrally provided upright via a shoulder portion 5 having a truncated pyramid shape. Is configured.

A central circumferential groove 4 for reinforcement is formed around the entire circumference of the body portion 2 at a substantially central height position of the body portion 2, and a longitudinal side cylindrical wall portion of the body portion 2 facing front and back is provided. A concave portion 3 is recessed in the center of the structure so that the upper half is located in the central circumferential groove 4.

The recess 3 has a height width larger than the groove width of the central circumferential groove 4 (FIGS. 1, 2, 3 and 4).
Therefore, it has an appearance that the groove width of the central circumferential groove 4 where the concave portion 3 is located bulges downward and becomes large.

Further, the concave portion 3 has a relatively large lateral width, and even if the body portion 2 is grasped by one hand from either side,
The side edge portion is located at a location (see FIGS. 1 and 5) where the fingertip of one hand can enter the recess 3.

Further, the concave portion 3 has a depth (see FIG. 2) larger than that of the central circumferential groove 4 to ensure that the fingertip that has entered the concave portion 3 is caught laterally.

In the case of the illustrated embodiment, since the concave portion 3 is integrally formed with the central circumferential groove 4 for reinforcement, the body portion 2 portion in which the concave portion 3 is provided has a flat wall structure to prevent pressing force. On the other hand, even in the case of the long side tube wall portion that is easily bent and deformed, when holding with one hand, the tubular wall portion of the body portion 2 provided with the concave portion 3 is held with one hand by the reinforcing effect of the central circumferential groove 4. As the operation is deteriorated, it is not flexibly deformed, which makes it possible to more stably handle the bottle body 1 with one hand when the fingertip is inserted into the concave portion 3.

Further, since the concave portion 3 is provided in the long side tube wall portion of the bottomed rectangular tube-shaped body portion 2, it is possible to grasp the short side tube wall portion when holding the body portion 2 with one hand. As a result, even if the bottle body 1 is a large bottle body, it is possible to stably hold the bottle body 1 with one hand and to make it good.

[0022]

Since the present invention has the above-described structure, the following effects can be obtained. Since the recess is simple and relatively small, it does not stand out as the appearance of the bottle, and there is no danger of the appearance of the bottle being deteriorated by shaping the recess, and there is no discomfort in the bottle. Appearance can be obtained.

Since the concave portion has a simple depressed structure and the gripping direction of the body portion is not specified to one of the two sides, the direction of the handling of the bottle body is not restricted, so that the bottle body There is no inconvenience in handling.

Since the concave portion has a simple depressed structure and is relatively small, it is easy to shape the concave portion molding portion on the molding die regardless of whether it is an existing structure or a new structure. Can be carried out.
