Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to caps for makeup tools, correction tools, applicators, writing tools and the like. More specifically, the present invention relates to a cap such as a writing instrument that can be connected to each other.

[0002]

In a conventional double-head type writing instrument such as, when that referred brush to expose one of the nib, construction cap has been deposited there, linked by such other engagement means on the top of the cap It has been known. However, if an infant or the like accidentally swallows the connected cap in the connected state, a choking accident may occur.

In recent years, many caps such as writing implements have been proposed in which an axial air passage is provided in advance for the purpose of preventing suffocation due to accidental ingestion of an infant or the like. However, all of them take into consideration the air circulation of the cap alone, but no attention was paid to the connected cap, and the safety was insufficient.

[0004]

The present invention [invention Problems Trying to solve] been made to solve the conventional problems, provides a cap, such as a writing instrument that does not smother also cap connected state as swallowed infants like What you want to do.

[0005]

SUMMARY OF THE INVENTION The present invention is directed to a cap such as a writing instrument that can be connected to each other, and each cap 1.
Set 2 in the axial direction of the air passage 3 for the prevention of asphyxiation ingestion communicating from one end to the other end between the outer cylinder 6 and the inner cylinder 7
A plurality of axial ribs 31 are attached to the outer peripheral wall of the inner cylinder 7.
The caps 1 and 2 are provided so as to be exposed from the tops. When the caps 1 and 2 are connected to each other, the cap 1
The rib 31 is engaged with the inner wall of the opening of the other cap 2.
The gist of the present invention is that each of the air passages 3 communicates with the engaging portion 41 .

The air passage 3 may be formed inside the cap or outside the cap as long as it communicates from one end to the other end of the cap.

The caps 1 and 2 need only be connectable to each other, and may have the same size or shape, or may have different sizes.

[0008]

The air passage 3 in which each of the caps 1.2 communicates from one end to the other end is connected to a connecting portion 4 (engagement) of the caps 1.2.
Since the communication is continued without interruption at the section 41), even if an infant or the like accidentally swallows the caps 1 and 2 in the connected state, the caps 1 and 2 will not be suffocated.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.

[0010] A real施例in FIGS. Each of the caps 1 and 2 includes an outer cylinder 6 and an inner cylinder 7. The inner cylinder 7
A plurality of axial ribs 31 are formed on an outer peripheral wall, and an annular airtight portion 5 composed of an annular projection is provided on an inner peripheral wall, and the inner cylinder 7 is fixed to the front end opening of the outer cylinder 6 by the rib 31. Have been.

A vertical groove 32 is formed between the ribs 31 so that an axial air passage 3 communicating from one end to the other end of the cap is formed inside the cap. In addition, the rib 31 is exposed forward from the top of the cap 1 to form the engaging portion 41, and the circumscribed circle diameter thereof is set slightly larger than the inner diameter of the opening of the other cap 2, so that other ribs 31 are formed. It is configured to be able to engage with the opening of the cap 2. Therefore, when the caps 1 and 2 are connected to each other, the air passage 3 may be closed even though the opening of one cap 2 and the inner cylinder 7 of the other cap 1 are engaged. Instead, an axial air passage 3 is secured in each of the connected caps 1 and 2.

[0012] It should be noted that, before you施例, each of the cap 1 and 2
Since they have the same shape, the cap 1 can be engaged with the top of the cap 2, contrary to the state shown in the drawing.

[0013]

[Effect of the Invention] The present invention has the above-described structure,
Even if an infant or the like accidentally swallows the connected caps, the air passage communicating from one end to the other end of each cap is continuously connected at the connecting portion of the caps, so it is possible to suffocate. Absent.
