Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) This is a description of a nose plug for filtering dust and pollen floating in the air and preventing runoff of nasal discharge.

(Prior Art) Conventionally, a nose plug made of absorbent cotton or a porous synthetic resin having open cells is generally used.

(Problems to be Solved by the Invention) However, absorbent cotton has water absorbency, but since it is formed of short fibers, the fibers are easily broken, and this adheres to the mucous membrane of the nostrils and causes irritation.

In addition, a nose plug made of synthetic resin such as open-cell polypropylene is rich in water absorption and there is no risk of tearing,
Not only is the air flow insufficient, but the cross section of the end face of the nose plug has sharp protrusions due to the presence of air bubbles, which may cause irritation by touching the inner surface of the nostril, and the whole body is hard and does not fit into the nostril. is there.

The present invention focuses on the fact that the acetate fiber is a safe medical material together with polypropylene, and utilizes the property that the polypropylene non-woven fabric and the long fiber acetate are not likely to be torn off, thereby forming a nose plug, The purpose is to prevent the nose plug from being inserted too deep into the nostril.

(Means for Solving the Problem) A plasticizer is added to the central portion 2 of a column 1 in which long filaments of acetate are bundled, and the outer periphery of the column is covered with a polypropylene nonwoven fabric 3 (claim 1).

Then, the central portion of the thin connecting wire 4 such as stainless steel is bent upward, and the plastic material of the pillar 1 is added to the hook-shaped bent portions 5 covered with the synthetic resin material at the left and right ends thereof. The central portion 2 is inserted and connected (claim 2).

(Function) The aggregate of long fibers of acetate in the central portion 2 of the columnar body 1 has rigidity and elasticity by adding a plasticizer,
When the hook-shaped bent portions of the connecting wires of the left and right nose plugs as described in claim 2 are inserted, the hook-shaped bent portions are tightly connected by elastically connecting the hook-shaped bent portions, and the nose plug does not come out unintentionally.

Moreover, breathing air circulates well through the gaps formed by the long fibers of acetate, during which dust, pollen or nasal discharge adheres to the long fibers and is removed.

(Example) As shown in Fig. 3, about 25,000 filaments of wavy acetate acetate having a length of about 1 cm were bundled, and a plasticizer was added to the central portion 2 to form a pillar 1. The outer circumference is covered with polypropylene nonwoven fabric 3.

By doing so, the gap between the long fibers becomes about 0.3 μm, and the air flows well through the gap from the starting end to the terminating end of the columnar body 1.

Triacetin is added as a plasticizer to the central portion 2 of the column to impart appropriate hardness and elasticity to the acetate fiber.

Instead of triacetin as a plasticizer, CMC (carboxy
(Methyl cellulose) binder may be used. CMC is a starchy adhesive and is a known substance as a food additive, and is excellent in that it has no acetic acid odor like triacetin.

Then, as shown in FIG.
The center part of the is bent upward, and the left and right ends are bent downward to form a hook-shaped bent portion 5. The hook-shaped bent portion 5
Is flatly covered with polypropylene and is inserted into the central portion 2 of the column 1 to connect the column 1 to the hook-shaped bent portion 5.

In addition, in order to appropriately cure the central portion 2, it is conceivable to increase the fiber density as compared with the peripheral portion without using a plasticizer.

(Effect of the invention) The columnar body 1 according to the invention of claim 1 bundles the long fibers of acetate, so that not only the air circulation is good, but also the outer periphery is covered with the polypropylene nonwoven fabric 3, so that the long fibers inside Has a long columnar shape and does not break like absorbent cotton, and the central portion 2 to which a plasticizer is added is appropriately hard and elastic, so that the column 1 is provided with a connecting wire according to claim 2 of the present invention. Can be inserted and held well, and since no plasticizer is added to the peripheral part of the pillar 1, it is soft and fits the shape of the nostril well unlike the conventional open cell synthetic resin nose plug. Since the end surface of the upper column 1 is composed of the cross section of the long fiber covered with the non-woven fabric 3, no sharp protrusion is formed on the end surface unlike the conventional open cell synthetic resin nose plug.

Next, according to the present invention of claim 2, since the left and right pillars 1 are inserted and connected to the hook-shaped bent portions 5, the pillars 1 are not blocked by the hook-shaped bent portions and do not enter the deep part of the nostrils unintentionally. Not only is it safe, but the part that appears to the outside across the nasal bridge that divides the left and right nostrils is only the central part of the connecting line 4, so even if the nose plug of the present invention is used, there is no danger of being visible. Moreover, since the hook-shaped bent portion 5 of the connecting wire 4 is formed thick by being covered with a synthetic resin, the tip of the hook-shaped bent portion is formed on the inner surface of the nostril as compared to when the connecting wire 4 is directly inserted into the pillar 1. There is no danger of scratching even if touched, and it is hard to come off, and it is medically safe because it is made of acetate or polypropylene material.
