Abstract

(57) [Abstract] [Purpose] An object of the present invention is to provide a writing instrument cap that has a simple structure and is safe even if it accidentally gets stuck in the throat. [Structure] A writing instrument cap in which a clip is integrally attached to a top side surface of a bottomed cylindrical lid body having an inner cylinder for sealing a pen body of a writing instrument main body through a connecting portion,
The tip of the clip 3 extends to be equal to or larger than the opening of the lid 1, and both sides of the connecting portion 31 of the clip 3 are cut out to form the ventilation portion 6.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a writing instrument cap that is safe even if it is accidentally clogged in the throat.

[0002]

[Prior Art]

 In writing instruments that use ink, a cap is used to prevent evaporation of the ink when not in use. In other words, the writing instrument cap has a function of keeping the pen body airtight and preventing the evaporation of ink.

[0003]

[Problems to be solved by the device]

 By the way, when writing, the cap is separated from the body of the writing instrument, but its size is almost the same as a "pacifier" for infants, so it may be put in the mouth by an infant. And if you accidentally swallow it and get stuck in your throat, the writing instrument cap, which has the function of keeping the pen body airtight and preventing the ink from evaporating, has a cylindrical shape with a bottom and is not breathable. Therefore, he / she cannot breathe, and there is a risk of suffocation.

For this reason, there is a demand for a writing instrument cap that is safe even if it accidentally gets stuck in the throat. It is very difficult to do.

Therefore, the present invention has an object to provide a writing instrument cap that has a simple structure and is safe even if it accidentally gets stuck in the throat.

[0006]

[Means for Solving the Problems]

 In order to achieve such an object, the writing instrument cap of the present invention has a clip via a connecting portion on the top side surface of a bottomed cylindrical lid having an inner cylinder for sealing the pen of the writing instrument main body. In the writing instrument cap that is attached integrally, the tip of the clip extends to be equal to or larger than the abutment of the lid, and both sides of the connecting portion of the clip are cut out to form a ventilation portion.

[0007]

[Action]

 That is, the pen body of the writing instrument body is sealed by the inner cylinder formed in the lid body, but since the ventilation part is formed by cutting out both sides of the clip connecting part, the gap between the clip inner surface and the lid outer peripheral surface is formed. Further, the top part of the lid and the abutment communicate with each other by the ventilation part. Therefore, even if it accidentally gets stuck in the throat, it is possible to breathe through this communication passage, and it is possible to provide a safe writing instrument cap that has a very simple structure and is airtight and breathable.

【Example】

 The present invention will be described in detail below with reference to the embodiments shown in the drawings. In FIG. 1, a lid 1 is a bottomed tubular body formed of a synthetic resin, and an inner tube 2 is directed inward toward a top portion 1a of the lid 1 which is the bottom of the bottomed tubular body. They are arranged in a row. A plurality of vertical ribs 4 are formed inside the lid body 1. When the lid body 1 is fitted into the writing instrument body (not shown) through the abutment 1b, the vertical ribs 4 are attached to the writing instrument body. The pen body is kept in contact with the front opening to maintain the posture of the writing instrument body, and the pen body is sealed by the inner cylinder 2 to prevent ink evaporation.

Next, the clip 3 is integrally attached to the side surface of the top portion 1a of the lid 1 via a connecting portion 31. In addition, in order to reinforce the connecting portion 31, a narrow reinforcing portion 32 is also formed continuously with the connecting portion 31. Here, the tip 3a of the clip 3 extends to be equal to or larger than the abutment 1b of the lid 1, and is longer than an ordinary clip. Then, as shown in FIG. 2, both sides of the connecting portion 31 are cut out to form the ventilation portion 6. Therefore, the gap 5 between the inner surface of the clip 3 and the outer peripheral surface of the lid 1 is connected to the ventilation portion 6 to form a communication passage between the top portion 1a of the lid 1 and the abutment 1b.

Even if the cap having the above-described structure separated from the writing instrument body is accidentally packed in the throat, the throat does not come into close contact with the gap 5 and the ventilation part 6, and the top part 1a of the lid 1 and the abutment part 1b communicate with each other. To do. Therefore, it is possible to breathe through the gap 5 and the ventilation portion 6, and it is possible to avoid the worst situation.

[0011]

[Effect of the device]

 As described above, the writing instrument cap of the present invention is formed by cutting out both sides of the connecting portion of the clip to form a ventilation portion so as to communicate with the gap between the inner surface of the clip and the outer peripheral surface of the lid. Even if the throat is accidentally clogged, it is possible to breathe through the communication passage, and the writing instrument cap has a simple structure and is safe.
