Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a fixture for fixing a plastic net of a vial whose entire outer surface is covered with a plastic net.

(Prior Art) Vials have conventionally been widely used for blood transfusions or for infusion of Ringer's solution, glucose solution, etc. Since the vial is used in an inverted state, it is necessary to stably hold the vial, so a vial hanging tool made of synthetic resin or the like is attached to the vial.

However, in the case of a vial equipped with such a conventional hanging device, the hanging device itself is expensive, making the cost of the vial extremely high. Therefore, the present applicant devised a new vial whose entire outer surface was covered with plastic net as shown in Fig. 3, and previously proposed it in Utility Application No. 58109/1983. .

(Problem to be solved by the invention) However, the above-mentioned vial covered with a plastic net uses a fixing ring made of three-dimensional synthetic resin to fix the net. Since the fixing ring has a three-dimensional structure, it has disadvantages such as poor productivity, inconvenience in transportation and storage, and high cost. Therefore, it has been desired to develop a plastic net fixture that can solve these problems.

(Means for solving the problem) The present invention was completed in order to solve the conventional problems, and it is a method of fixing the plastic net of a vial whose entire outer surface is covered with a plastic net. The fixture is configured in the shape of a donut plate consisting of two concentric circles, large and small, and has a plurality of notches radially carved from the small circle toward the large circle, and the entire is characterized in that it is made of an elastic material and is constructed in a planar manner.

(Embodiments) Next, the present invention will be described in detail with reference to illustrated embodiments.

Figure 1 shows the plastic net fixing device 1 of the present invention.
The entire structure is made of polypropylene, and the entire structure is planar as shown in FIG. 2, which is a sectional view taken along line A-A. The fixture 1 has a donut plate shape consisting of two large and small concentric circles with radii R1 and R2, and a cut portion 4 having a length R3 from the small circle 2 to the large circle 3.
are engraved in six radial shapes.

As shown in FIG. 3, the plastic net fixing device 1 constructed in this way is used to fix the net 5 of a glass vial 6 whose entire outer surface is covered with a cylindrical plastic net 5. It will be attached to the mouth of No.6. In this case, the fixture 1 is configured so that the sum [R1+R3] of the radius R1 of the small circle 2 and the length R3 of the notch 4 is slightly larger than the radius of the flange 7 of the vial 6. The tool 1 can be easily pushed into the vial 6 from the mouth side by deforming it using the elasticity of polypropylene.

FIG. 4 is an enlarged view of the lower part of FIG. 3, and is partially sectional. As is clear from FIG. 4, after the fixture 1 is attached to the mouth of the vial 6, the radius R2 of the large circle 3 is larger than the inner diameter of the ring 9 that holds the bent portion 8 of the plastic net 5. is also configured to be slightly larger, so
The fixing device 1 does not enter the inside of the ring 9, and the fixing device 1 is deformed by the elasticity of the polypropylene forming the fixing device 1, and the fixing device 1 is deformed between the flange 7 of the vial 6 and the ring 9. It is firmly fixed. As a result, the ring 9 is firmly fixed in place via the plastic net 5, and the fixing device itself is securely fixed to the mouth of the vial by the restoring force generated from the elasticity of polypropylene, and the plastic This will fully demonstrate its function as a net fixing tool.

As for the material constituting the fixture of the present invention, in addition to the polypropylene shown in the examples, any material having similar strength and elasticity such as synthetic resin, paper, thin metal plate, or composite material can be used. or,
It goes without saying that the number of notches is not limited to six; any number may be sufficient as long as it achieves the same effect, and it is preferable to form 4 to 8 notches for functional purposes. desirable.

The vial coated with the plastic net constructed as described above will eventually have a hanging handle 10 formed at the bottom of the bottle, as shown in FIG. 3, and will be fitted with a conventional hanging device. Similarly, the vial is held in an inverted state by being suspended by the hanging handle 10, and is used for dripping or the like.

(Effect of the invention) As is clear from the above explanation, the plastic net fixing device according to the present invention can extremely easily and firmly fix the plastic net coated on the outer surface of the vial and the ring of the net. In addition, since the entire structure is flat, it is easy to manufacture and production costs can be significantly reduced, and it also exhibits various effects such as being extremely easy to transport, store, and handle. It is something.

Thus, the present invention provides a novel plastic net fixing device with various effects.
It has excellent practical value.
