JPS5925398Y2 - Bottom suspension structure for infusion containers, etc. - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to a bottom suspension structure of an infusion container, particularly a plastic bottle.

In a conventional infusion container, for example, as shown in FIG. 1, a concave groove C is formed on the bottom surface of a synthetic resin infusion bottle a, and
A fitting recess d is formed by notching a corner of the bottle barrel in line with the groove C, and a hanging ring e is formed approximately at the center of the groove C so that it can rise and fall freely. When not in use, the suspension ring e was held lying down and its tip was press-fitted into the fitting recess d to be fixed.

However, according to such a configuration of the prior art, it is necessary to raise and lower the suspension ring e each time during filling or use, which is cumbersome to operate.

In addition, if the engagement between the tip of the hanging ring e and the fitting recess d is weak, the hanging ring e will stand up due to its own elastic force and protrude outward from the bottom of the bottle to maintain its erect state. This makes it inconvenient to handle when filling.

Furthermore, in such prior art, it is necessary to form a separate hanging ring e in the groove C or provide a fitting recess d in the corner of the bottle body, which makes the manufacturing process slow. This has disadvantages such as not only the production is complicated but also expensive.

Therefore, the purpose of the present invention is to provide a flange with a retaining hole in the recess provided on the bottom of the container body so as to be perpendicular to the ground surface of the container so that the raising and lowering operation can be performed at any time. It is an object of the present invention to provide a product that can be stably erected immediately or simply hung on a hook when necessary, is easy to manufacture, and is inexpensive.

The present invention will be explained below based on the illustrated embodiments. In FIGS. 2 to 6, 1 is a container body such as a plastic bottle for infusion, and 2 is a center portion of the bottle with the bottom surface of the container body 1 in two stages. A flat bottom ground plane is formed on both sides of the outer edge when the bottle is recessed, 3 is a stepped part formed on the inside in continuation with the bottom ground plane 2, and 4 is a bottle continuously formed further inside this stepped part 3. The recesses 4 extend along the entire length in the thickness direction of the bottle, and the recesses 4 are formed in a curved shape that gradually inclines toward the center of the bottle in the width direction of the bottle.

Reference numeral 5 designates a plate-shaped flange provided at the center of the concave portion 4 so as to extend in the direction of extension of the concave portion 4, that is, in a direction transverse to the thickness direction of the bottle. A retaining hole 6 for engaging a hook F is provided at the center located at the bottom of the groove.

Further, the free edge 5a of the flange 5 is recessed so as not to protrude outward from the bottom ground plane 2, thereby ensuring stability when standing upright.

The engagement hole 6 of the flange 5 is located within the concave portion 4 and opens in the direction in which the concave portion 4 extends.

The above-mentioned flange 5 utilizes the burr formed at the bottom of the bottle when a plastic bottle is produced by blow molding, and the engagement hole 6 is formed by drilling a hole in the flange.

Therefore, since the flange 5 is integrally molded with the plastic bottle at the same time, its formation is simple.

However, the method of forming the flange 5 of the present invention is not limited to this method; for example, a separate flange may be fixed in the recessed portion 4 by appropriate means.

In addition, for the retaining hole 6 drilled in the center of the flange 5, the hole diameter, installation location, etc. can be arbitrarily selected so that the engagement hole can easily be engaged with the tip of the hook F when used as shown in FIG. .

In the illustrated embodiment, a single retaining hole 6 is provided in the flange 5, but if necessary, two or more sets of holes may be provided.

To explain the operation of the bottom structure of the infusion container, etc. of the present invention having the above-mentioned configuration, as shown in FIG. 5a is recessed inward from the bottom ground plane 2, so you can simply place the bottom ground plane 2 on the bottom of the table without having to do any horizontal operation of the hanging ring as in the conventional case. It can be erected extremely stably.

On the other hand, when using Fig. 5, there is no need to raise the hanging ring like in the past, and the plastic bottle can be turned upside down.
If the engaging hole 6 of the flange 5 is hooked to the hook F, it can be used as needed immediately.

In this case, the concave portion 4 is formed in a curved shape that gradually inclines toward the center of the bottle in the width direction of the bottle, so that it acts as a guide when the hanging hook F is passed through the hole.

Moreover, the retaining hole 6 of the flange 5, which is provided in a direction transverse to the extending direction of the recessed part 4, is located within the recessed part 4 at the bottom of the curved groove and opens in the extending direction of the recessed part. Therefore, by advancing the hook F along the concave portion 4, the locking operation can be completed relatively easily.

As described above, the present invention provides a flange with an engaging hole in the recess provided on the bottom surface of the container body so as to be perpendicular to the surface of the container, thereby eliminating the need for raising or lowering the container at any time. It has the advantage that it can be stably erected or easily hung on a hook when necessary.

Further, since the flange with the engaging hole is molded simultaneously with the bottle and has a simple structure, it is easy to manufacture and has the advantage that the product can be provided at a low cost.
