Abstract

PURPOSE: To ensure air circulation gallery and protecting the person from suffocating In the event of the cap swallowed by accident by forming the width of longitudinal grooves made by adjoining ribs equally at one end side and another end side. CONSTITUTION: The cap 1 is constructed such that the opening 2 side is large in diameter, the bottomed part 3 side is a small-diameter tapered bottomed part, and a plurality of longitudinal ribs 4 are formed over the entire length from the end part of the opening 2 to the end part of the bottomed part 3. The plurality of longitudinal ribs 4 are made narrower at the bottomed part 3 side than the opening part 2 side in width. Thus, with respect to the width of the longitudinal grooves 5 defined between the longitudinal adjoining ribs, the width 5a in the opening 2 and the width 5b in the bottomed part 3 are made equal. In this manner, a constant air circulation can be ensured irrespective of the direction of a cap swallowed by mistake and the length of the cap taken into the bronchus.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention provides an air circulation hole when a cap swallowed accidentally becomes stuck in the bronchus,
The present invention relates to a cap for a writing instrument, an applicator, or the like that prevents suffocation.

[0002]

2. Description of the Related Art When an infant or a child uses a writing instrument, an applicator or the like, an accident may occur in which the cap is accidentally swallowed. Therefore, there has been proposed a cap capable of ensuring an air circulation hole and preventing suffocation even if the cap swallowed accidentally is clogged in the bronchus. For example, in Japanese Utility Model Laid-Open No. 3-9879, an inner cap is provided upright in an inner hole of a cap, a proper window hole is formed in a bottom wall of the inner hole, and the window hole and the inner hole are communicated with each other. By doing so, air circulation is secured, the cap is accidentally swallowed,
Even if the bronchus is blocked, it is disclosed to avoid suffocation.

[0003]

However, the cap described above has a problem that the structure is complicated and the manufacturing cost is high. In addition, since the cap as described above has an inner cap, the diameter of the cap itself becomes large, so that when the cap is fitted to a writing instrument, an applicator or the like, the appearance is impaired. In particular, when it is used in a writing instrument or an applicator that has been commercialized in the related art, only the cap is large and the balance becomes poor. As a simple structure to secure the air circulation hole, it is considered to provide a plurality of vertical ribs over the entire length on the outer wall of the cap, and make the vertical groove formed between the adjacent vertical ribs the air circulation hole. To be But once,
For example, when a vertical rib is formed on the outer wall of the cap where the opening side has a large diameter and the other end, for example, the bottomed side has a small diameter,
Conventional ribs usually have a constant width over their entire length, so that the width of a vertical groove having a small diameter on the bottom side is narrowed. Since the air flow rate is determined by controlling the portion where the cross-sectional area of the air flow hole is the smallest, effective air flow cannot be secured depending on the width of the vertical groove on the bottomed side having a small diameter.

The present invention provides a cap having a simple structure, a diameter as small as possible, and ensuring air circulation.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems. One end has a large diameter and the other end has a small diameter, and an outer wall is provided with a plurality of vertical ribs extending over the entire length. The gist of the cap is that the vertical groove formed by the adjacent vertical ribs has the same width on the one end side and the other end side.

[0006]

In the cap of the present invention, the width of the vertical groove formed by the adjacent vertical ribs is substantially constant at any position of the cap. Therefore, the direction of the cap when accidentally swallowed and the length of immersion of the cap into the bronchus. Regardless of the size, a certain air flow can be secured.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the accompanying drawings. 1 to 4 show an embodiment of the present invention. FIG. 1 is a front view of this embodiment. 2 is a vertical cross-sectional view of FIG.
3 and 4 are a bottom view of FIG. 1 and a top view of FIG. 1, respectively. The cap 1 is a tapered bottomed cylindrical body having a large diameter on the opening 2 side and a small diameter on the bottomed portion 3 side, and the outer wall thereof has the entire length from the opening 2 end to the bottomed 3 end. A plurality of vertical ribs 4 are formed. This plurality of vertical ribs 4
Is formed such that its width is smaller on the bottomed portion 3 (small diameter portion in this embodiment) side than on the opening 2 (large diameter portion in this embodiment) side. As a result, the width of the vertical groove 5 formed between the adjacent vertical ribs 4 is the same as the width 5a of the opening 2 and the width 5b of the bottomed portion 3.

In this embodiment, the opening 2 side has a large diameter and the bottomed portion 3 side has been described as a cap made of a tapered bottomed cylindrical body. However, conversely, the bottomed portion side has a large diameter,
The opening side may be a cap made of a tapered cylindrical body having a small diameter. In this case, the width of the vertical rib may be thicker on the bottomed side than on the opening side.

[0009]

Since the cap according to the present invention has the above-mentioned structure, even if the cap is accidentally swallowed and the bronchus is clogged, the air circulation hole is secured and suffocation does not occur. Also, a constant air flow can be secured regardless of the direction of the swallowed cap and the length of immersion into the bronchus.
