【0001】[0001]

【産業上の利用分野】[Industrial applications]

本考案は、化粧具、修正具、塗布具、筆記具等のキャップに関する。さらに詳 細には、相互に連結可能な筆記具等のキャップに関する。 The present invention relates to a cap such as a makeup tool, a correction tool, an application tool, and a writing tool. More specifically, it relates to a cap such as a writing instrument that can be connected to each other.

【0002】[0002]

【従来の技術】[Prior art]

従来両頭式筆記具等において、一方のペン先を露出させて筆記具する際、そこ に被着されていたキャップは、他方のキャップの頂部に係合手段などによって連 結される構成が知られている。しかし、前記連結したキャップを、連結状態のま ま、万一、幼児等が誤って飲み込んだ場合、窒息事故を発生させるおそれがあっ た。 Conventionally, in a double-headed writing instrument, it is known that when one writing pen is exposed with the tip of the pen exposed, the cap attached to the pen is connected to the top of the other cap by an engaging means or the like. . However, if an infant or the like accidentally swallows the connected cap while the cap is connected, there is a risk of causing a choking accident.

【0003】 また、近年、筆記具等のキャップにおいて、幼児等の誤飲による窒息防止の目 的で、予め軸方向の空気通路を設けたものが多く提案されている。ところが、そ れらの全て、キャップ単体での空気流通を考慮しているが、連結状態のキャップ については何ら注意が払われておらず、安全性が不十分であった。Further, in recent years, many caps such as writing implements have been previously provided with an axial air passage in order to prevent suffocation due to accidental ingestion by an infant or the like. However, although all of them take into consideration the air circulation in the cap alone, no attention was paid to the cap in the connected state, and the safety was insufficient.

【0004】[0004]

【考案が解決しようとする課題】[Problems to be solved by the device]

本考案は前記従来の問題点を解決するものであって、連結状態のキャップを幼 児等が誤って飲み込んだとしても窒息させることない筆記具等のキャップを提供 しようとするものである。 SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems, and aims to provide a cap for a writing instrument or the like that does not cause suffocation even if a child or the like accidentally swallows the connected cap.

【0005】[0005]

【課題を解決するための手段】[Means for Solving the Problems]

本考案は、相互に連結可能な筆記具等のキャップであって、各々のキャップ1 ・2が一端から他端に連通する、誤飲による窒息防止のための軸方向の空気通路 3を備えるとともに、各々のキャップ1・2を相互に連結した際、その連結部4 にて前記各々の空気通路3が連通してなることを要旨とする。 The present invention is a cap such as a writing instrument which can be connected to each other, and is provided with an axial air passage 3 for preventing suffocation due to accidental ingestion, in which each cap 1 and 2 communicates from one end to the other end, The point is that when the caps 1 and 2 are connected to each other, the air passages 3 communicate with each other at the connecting portion 4.

【0006】 前記連結部4は、嵌合、圧入、螺合、係合等、何れの手段を適用してもよい。 また、前記連結部4は、キャップ頂部とキャップ開口部が連結する構成、互いの キャップ頂部が連結する構成、互いのキャップのキャップ側部が連結する構成等 が有効である。Any means such as fitting, press-fitting, screwing, and engaging may be applied to the connecting portion 4. Further, it is effective that the connecting portion 4 has a configuration in which the cap top portion and the cap opening portion are coupled, a configuration in which the cap top portions are coupled, a configuration in which the cap side portions of the caps are coupled, and the like.

【0007】 また、空気通路3は、キャップの一端から他端に連通していれば、キャップの 内部やキャップの外部のどちらに形成してもよい。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.

【0008】 また、各々のキャップ1・2は、相互に連結可能であればよく、それぞれの大 きさ、形状等は同一、あるいは相違していてもよい。Further, the caps 1 and 2 only need to be connectable to each other, and their sizes, shapes, etc. may be the same or different.

【0009】[0009]

【作用】[Action]

各々のキャップ1・2が一端から他端に連通する空気通路3が、キャップ1・ 2相互の連結部4にて途切れることなく連通しているので、万一、連結状態のキ ャップ1・2を、幼児等が誤って飲み込んだとしても、窒息させることがない。 Since the air passages 3 that connect the respective caps 1 and 2 from one end to the other end are continuously connected to each other at the connecting portion 4 between the caps 1 and 2, the caps 1 and 2 in the connected state should by any chance. Even if an infant or the like swallows it by mistake, it does not cause suffocation.

【実施例】【Example】

本考案実施例を図面に従って説明する。 Embodiments of the present invention will be described with reference to the drawings.

【0011】 図1乃至図3、及び図8に第一実施例を示す(一組の同一のキャップ1・2が 連結状態となっている)。各々のキャップ1・2は、プラスチック材料を射出成 形により得られ、その内周壁には、ペン先を密閉するための平滑面よりなる環状 気密部5が設けられる。前記環状気密部5の前方の各々のキャップ1・2外周壁 には、複数の軸方向のリブ31が軸心より放射状に突設され、該リブ31の間に 縦溝32が形成される。また、前記環状気密部5の外周には、環状溝33が設け られ、該環状溝33には、キャップ内と連通する通気孔34(4個)が開口して いる。1 to 3 and 8 show a first embodiment (a set of identical caps 1 and 2 is in a connected state). Each of the caps 1 and 2 is obtained by injection molding a plastic material, and an annular airtight portion 5 having a smooth surface for sealing the pen tip is provided on the inner peripheral wall thereof. A plurality of axial ribs 31 are provided radially on the outer peripheral wall of each of the caps 1 and 2 in front of the annular hermetic portion 5 so as to radially project from the axial center, and a vertical groove 32 is formed between the ribs 31. Further, an annular groove 33 is provided on the outer periphery of the annular airtight portion 5, and the annular groove 33 has vent holes 34 (four) communicating with the inside of the cap.

【0012】 また、各々のキャップ1・2の頂部外周壁には、縮径段部よりなる係合部41 が設けられている。前記係合部41のリブ31外接円径は、各々のキャップ1・ 2開口部の内径より僅かに大きく設定されているため、両頭式筆記具において、 一方のキャップの開口部内壁と係合され、使用時のキャップの後ろ差しが可能と なる(図8参照)。Further, an engaging portion 41 composed of a reduced diameter step portion is provided on the outer peripheral wall of the top portion of each of the caps 1 and 2. The rib 31 circumscribed circle diameter of the engaging portion 41 is set to be slightly larger than the inner diameter of each cap 1 and 2 opening portion, so that in the double-headed writing instrument, the rib 31 is engaged with the inner wall of the opening portion of one cap, It is possible to insert the cap behind when using it (see Fig. 8).

【0013】 本実施例では、空気通路3は、通気孔34の後方ではキャップ内部、通気孔3 4の前方では縦溝32によってキャップ外部に形成され、環状溝33においてキ ャップ内部とキャップ外部が連通している。前記空気通路3は、係合部41にお いて、一方のキャップ1の縦溝32と他方のキャップ2の内部が連通しているた め、両者の空気通路3が途切れることがない。In this embodiment, the air passage 3 is formed inside the cap behind the ventilation hole 34 and outside the cap by the vertical groove 32 in front of the ventilation hole 34, and the inside of the cap and the outside of the cap are formed in the annular groove 33. It is in communication. In the engaging portion 41 of the air passage 3, the vertical groove 32 of the one cap 1 and the inside of the other cap 2 communicate with each other, so that both air passages 3 are not interrupted.

【0014】 図4及び図5に第二実施例を示す(一組の同一のキャップ1・2が連結状態と なっいる)。各々のキャップ1・2内周壁には、環状突起よりなる環状気密部5 が設けられ、前記環状気密部5の前後位置には複数の軸方向の縦溝32が配設さ れている。前記環状気密部5の外周には前記縦溝32が途切れ、環状溝33が形 成される。これにより、前記環状気密部5の肉圧変動を除き、プラスチック射出 成形時のヒケを防止する。前後位置の縦溝32は前記環状溝33にそれぞれ連通 し、軸方向の空気通路3を形成する。A second embodiment is shown in FIGS. 4 and 5 (a pair of identical caps 1 and 2 are in a connected state). An annular airtight portion 5 made of an annular protrusion is provided on the inner peripheral wall of each of the caps 1 and 2, and a plurality of axial vertical grooves 32 are provided at the front and rear positions of the annular airtight portion 5. The vertical groove 32 is interrupted on the outer periphery of the annular hermetic portion 5 to form an annular groove 33. As a result, fluctuations in the wall pressure of the annular hermetic portion 5 are eliminated, and sink marks during plastic injection molding are prevented. The longitudinal grooves 32 at the front and rear positions respectively communicate with the annular groove 33 and form the air passage 3 in the axial direction.

【0015】 各々のキャップ1・2の頂部には、縮径段部よりなる係合部41が設けられ、 一方のキャップ1の前記係合部41に他のキャップ2の開口部が係合されている 。各々のキャップ1・2の開口端は、縦溝32が形成されておらず、連結の際、 環状の隙間35が形成されるので、各々のキャップ1・2の縦溝32が円周方向 にずれて連結されたとしても、スムーズな空気流通が可能となる。An engaging portion 41 composed of a reduced diameter step portion is provided on the top of each cap 1 and 2, and the engaging portion 41 of one cap 1 is engaged with the opening portion of another cap 2. ing . The vertical groove 32 is not formed at the open end of each cap 1 and 2, and an annular gap 35 is formed at the time of connection, so the vertical groove 32 of each cap 1 and 2 is formed in the circumferential direction. Even if they are connected in a shifted manner, smooth air circulation is possible.

【0016】 図6及び図7に第三実施例を示す。各々のキャップ1・2は、外筒6と内筒7 よりなる。前記内筒7は、外周壁に複数の軸方向のリブ31が形成されるととも に、内周壁に環状突起よりなる環状気密部5が設けられ、該内筒7が前記リブ3 1によって外筒6前端開口部に固着されている。A third embodiment is shown in FIGS. 6 and 7. Each of the caps 1 and 2 includes an outer cylinder 6 and an inner cylinder 7. The inner cylinder 7 has a plurality of axial ribs 31 formed on the outer peripheral wall thereof, and an annular airtight portion 5 formed of an annular projection is provided on the inner peripheral wall thereof, and the inner cylinder 7 is covered by the ribs 31. It is fixed to the front end opening of the cylinder 6.

【0017】 前記リブ31の間には、縦溝32が形成され、これにより、キャップの一端か ら他端に連通する軸方向の空気通路3が、キャップ内部に形成される。また、前 記リブ31がキャップ1の頂部より前方に露出され、係合部41が形成されると ともに、その外接円径が他のキャップ2の開口部内径より僅かに大に設定されて 、他のキャップ2の開口部と係合可能に構成されている。そのため、各々のキャ ップ1・2を相互に連結した際、一方のキャップ2開口部と他方のキャップ1の 内筒7が係合されているにもかかわらず、空気通路3は閉塞されることがなく、 連結状態の各々のキャップ1・2において軸方向の空気通路3が確保される。A vertical groove 32 is formed between the ribs 31, whereby an axial air passage 3 communicating from one end to the other end of the cap is formed inside the cap. 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 to be slightly larger than the inner diameter of the opening of the other cap 2. It is configured to be engageable with the opening of the other cap 2. Therefore, when the caps 1 and 2 are connected to each other, the air passage 3 is closed even though the opening of one cap 2 and the inner cylinder 7 of the other cap 1 are engaged. The air passage 3 in the axial direction is secured in each of the caps 1 and 2 in the connected state.

【0018】 尚、前記第一、第二、及び第三実施例は、各々のキャップ1・2は同一形状で あるため、図面に示す状態とは逆に、キャップ2の頂部にキャップ1を係合させ ることもできる。In the first, second and third embodiments, since the caps 1 and 2 have the same shape, the cap 1 is attached to the top of the cap 2 contrary to the state shown in the drawings. You can also combine them.
