Description

【０００１】
【発明の属する技術分野】
本発明はキャップに関する。
【０００２】
【従来の技術】
容器体口頚部に装着するキャップとして、口頚部外周に突条相互の乗り越え係合により抜け出しを防止して周壁を嵌合させ、また、周壁上端縁より内方へ延設した頂板により口頚部上端開口を閉塞し、頂板中央に薄肉の切断線により画成された切り取り蓋を設けてなる本体と、本体後部上端に後部下端を薄肉ヒンジを介して回動可能に連結するとともに、本体上面を開閉可能に閉塞する蓋体とからなるものが知られている。
【０００３】
【発明が解決しようとする課題】
これらのキャップは、例えば、切り取り蓋上面より立設した棒状突起上端のプルリングを引いて切断線の部分から切り取り蓋を取り除き使用するが、従来のこの種のキャップでは、容器体を傾けて収納液を注出使用する際に液圧でキャップが外れてしまうという不都合が生じる場合があった。この様な不都合を解消するためには、口頚部外周に嵌合させている嵌合筒の突条相互の係合をより係合強度の強いものとすれば解消するが、今度は廃棄の際に容易に取り外すことが出来ないという問題が生じる。
【０００４】
近年のゴミ処理事情により、廃棄物の分別処理が要望されており、ガラス，金属，合成樹脂の異種材質は勿論のこと、合成樹脂相互の分別も要望されている。従って、廃棄の際にはキャップを容器体より容易に外せることが望まれる。
【０００５】
本発明は上記した点に鑑みなされたもので、使用時には強固に口頚部に嵌合させておくことができ、注出時の液圧等で外れる虞がなく、使用後には簡単な操作により容易に口頚部から取り外すことができる合成樹脂製のキャップを提案するものである。
【０００６】
【課題を解決するための手段】
本請求項１発明のキャップは上記課題を解決するため、容器体Ｂの口頚部４外周に嵌合させた周壁５内面に突周設した係合突条６を、口頚部４外周に突周設した係止突条７下面を強制的に乗り越え係合させて抜け出しを防止するとともに、周壁５上端縁より延設した頂板８により口頚部４上端開口を閉塞し、且つ、頂板中央部には薄肉の切断線10に囲成された切り取り蓋11を備えてなる本体２と、本体後部上端部に後部下端部を薄肉ヒンジ15を介して回動可能に連結して本体上面を開閉可能に被覆した伏皿状の蓋体３とからなる合成樹脂製のキャップであって、周壁５を縦断する第１臨界線16と、第１臨界線16上端と離隔した周壁５上端位置より下方へ下った後係合突条６上方位置を第１臨界線16と反対側側方へ延びる第２臨界線17との間の周壁５部分を薄肉に形成し、第１臨界線16及び第２臨界線17間の頂板８縁部を貫通して、下端を周壁薄肉部分ａと口頚部４との間の隙間に開口した透孔18を穿設し、薄肉部分ａを各臨界線部分から切断可能に構成してなることを特徴とするキャップとして構成した。
【０００７】
また、請求項２発明のキャップは、上記透孔18が、薄肉ヒンジ15直前に形成した透孔である請求項１記載のキャップとして構成した。
【０００８】
また、請求項３発明のキャップは、上記第２臨界線17が、周壁５上端より垂下した後、下向きに湾曲し、次いで螺旋状に上昇して延びる第２臨界線17である請求項１記載のキャップとして構成した。
【０００９】
【発明の実施の形態】
以下、本発明の実施例の形態を図面を参照して説明する。
【００１０】
本発明のキャップＡは、本体２と、蓋体３とから構成している。
【００１１】
本体２は、容器体Ｂの口頚部４外周に嵌合させた周壁５底面に突周設した係合突条６を、口頚部４外周に突周設した係止突条７下面に強制的に乗り越え係合させて抜け出しを防止するとともに、周壁５上端縁より延設した頂板８により口頚部４上端開口を閉塞している。図示例では、頂板８下面周縁部より垂設したシール筒９を口頚部４内周に密嵌させてこの部分からの液漏れの防止を図っている。
【００１２】
頂板８中央部には薄肉の切断線10に囲成された切り取り蓋11を備えている。
【００１３】
切り取り蓋11の上面からは棒状突起12を立設し、該突起12の先端より水平状にプルリング13を延設している。このプルリング13を掴んで引くことにより、切断線を切断して切り取り蓋11を除去し、注出口を開口する如く構成している。切り取り蓋11の外方の頂板８上面からは注出筒14を立設している。
【００１４】
蓋体３は、本体２の後部上端部に後部下端部を薄肉ヒンジ15を介して回動可能に連結して本体上面を開閉可能に被覆した伏皿状をなしたものが使用される。
【００１５】
本発明では、上記した如きこの種のキャップに於いて、周壁５を縦断する第１臨界線16と、第１臨界線16上端と離隔した周壁５上端位置より下方へ下った後係合突条６上方位置を第１臨界線16と反対側側方へ延びる第２臨界線17との間の周壁５部分を薄肉部分ａに形成している。
【００１６】
また、第１臨界線16及び第２臨界線17間の頂板８縁部を貫通して、下端を周壁５の薄肉部分ａと口頚部４との間の隙間に開口した透孔18を穿設し、薄肉部分ａを各臨界線部分で切断可能に構成している。
【００１７】
透孔18の形成位置は、周壁５の周方向どの位置であっても良いが、蓋体３を持って各臨界線部分を切断するのが可能となる薄肉ヒンジ15直前部分に設けると良い。透孔18は少なくとも周壁５に掛かった位置に周壁５に沿って穿設し、薄肉部分ａと口頚部４との間の隙間に下端を開口する。第１臨界線16及び第２臨界線17部分の薄肉部分ａはその中央部の薄肉部分ａと同じ厚み幅に形成しても良いが、周壁５の肉厚、材質等により、各臨界線部分を他の部分ａより肉薄に形成し、より切断し易く構成することも可能である。
【００１８】
薄肉部分ａは上記透孔18と併せて、本体周壁５を部分的に切断し、本体を口頚部４から容易に取り外せる如くするためのもので、その形状は種々採用できるが、その第２臨界線17が係合突条６より上方位置に存在する必要がある。但し、第２臨界線17の極一部分が係合突条６より下方に位置する場合があっても、本発明の目的，効果を達成できるものではある。また、薄肉部分ａを特に切断させ易くするために、第２臨界線17を、周壁５上端より垂下した後、下向きに湾曲し、次いで螺旋状に上昇して延びる如く形成している。
【００１９】
第２臨界線17の設置長さとしては、特に限定されるものではないが、本体周壁５上端の一側に基端を発し、側方に延びてからは周壁５の周方向１／３〜１／２程度の長さに設けると、キャップを比較的容易に口頚部からの取り外しが行えるとともに、使用時には薄肉部分ａの存在があっても安定して口頚部４に装着させておくことが出来る。尚、第２臨界線17を、周壁を一周して第１臨界線16まで延設することも可能ではある。
【００２０】
この様なキャップＡを使用する場合には、プルリング13を引いて切断線10部分を切断して切り取り蓋11を取り除き使用する。この際には係止突条７と係合突条６との充分な係合強度を備えており、注出液の液圧でキャップが外れる等を防止している。また、容器体内収納液を使用後に廃棄する際には、透孔18上方より金属板等の道具19を挿入して、図２に示す如く、薄肉部分ａ両側の第１臨界線16及び第２臨界線部分を切断し、次いで、図３に示す如く、第２臨界線17の部分から周壁５を切断する。この際には手で蓋体３を持って行える。第２臨界線17がある程度まで切断されると、口頚部４から容易にキャップＡを外すことが出来る。尚、図示例の如く、透孔18が薄肉ヒンジ15部分に存在する場合には、上記した如き道具19を使用しないで、手で蓋体３を直接持って引き下げた後側方へ引っ張ることにより同様に各臨界線を切断することができる。
【００２１】
【発明の効果】
以上説明した如く本発明のキャップは、周壁５を縦断する第１臨界線16と、第１臨界線16上端と離隔した周壁５上端位置より下方へ下った後係合突条６上方位置を第１臨界線16と反対側側方へ延びる第２臨界線17との間の周壁５部分を薄肉に形成し、第１臨界線16及び第２臨界線17間の頂板８縁部を貫通して、下端を周壁薄肉部分ａと口頚部４との間の隙間に開口した透孔18を穿設し、薄肉部分ａを各臨界線部分から切断可能に構成したので、液の注出の為に容器を傾倒させた際に勢い良く容器体口頚部へ流出する液圧によりキャップが外れる等の不都合を防止するために、係止突条及び係合突条を充分な係合強度で係合させて不用意な外れを防止しても、収納液使用後は、簡単な操作により容器体から取り外すことができ、各部分の分別廃棄を行えるものである。
【００２２】
また、請求項２発明のキャップの場合には、金属板等の道具を使用せずに手で蓋体を持って薄肉部分を破断することができる利点を兼ね備えている。
【００２３】
また、請求項３発明のキャップの場合には、薄肉部分を無理なく簡単に切断することが出来る利点を兼ね備えている。

[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0010]
The cap A of the present invention includes a main body 2 and a lid 3.
[0011]
The main body 2 is forcibly provided with an engaging ridge 6 projectingly provided on the bottom surface of the peripheral wall 5 fitted to the outer periphery of the neck portion 4 of the container body B on the lower surface of the engaging ridge 7 provided projectingly on the outer periphery of the neck portion 4. The top neck 8 extending from the upper end edge of the peripheral wall 5 closes the upper end opening of the mouth neck portion 4. In the illustrated example, a seal cylinder 9 suspended from the lower peripheral edge of the top plate 8 is closely fitted to the inner periphery of the mouth neck 4 to prevent liquid leakage from this portion.
[0012]
At the center of the top plate 8, a cutting lid 11 surrounded by a thin cutting line 10 is provided.
[0013]
A bar-like protrusion 12 is erected from the upper surface of the cut-out lid 11, and a pull ring 13 is extended horizontally from the tip of the protrusion 12. By grasping and pulling the pull ring 13, the cutting line is cut to remove the cut lid 11, and the spout is opened. A pouring tube 14 is erected from the upper surface of the top plate 8 outside the cut lid 11.
[0014]
The lid 3 is formed in the shape of a flat plate in which a rear lower end is connected to a rear upper end of the main body 2 via a thin hinge 15 so that the upper surface of the main body can be opened and closed.
[0015]
In the present invention, in the cap of this kind as described above, the first critical line 16 that vertically cuts the peripheral wall 5 and the engagement protrusion after being lowered from the upper end position of the peripheral wall 5 that is separated from the upper end of the first critical line 16. 6 The peripheral wall 5 between the upper position and the second critical line 17 extending to the opposite side to the first critical line 16 is formed in the thin part a.
[0016]
In addition, a through-hole 18 is formed that penetrates the edge of the top plate 8 between the first critical line 16 and the second critical line 17 and opens the lower end in the gap between the thin portion a of the peripheral wall 5 and the neck 4. In addition, the thin portion a is configured to be cut at each critical line portion.
[0017]
The through hole 18 may be formed at any position in the circumferential direction of the peripheral wall 5, but it is preferably provided at a portion immediately before the thin-walled hinge 15 that can cut each critical line portion with the lid 3. The through-hole 18 is drilled along the peripheral wall 5 at least at a position hung on the peripheral wall 5, and the lower end is opened in the gap between the thin portion a and the mouth-neck portion 4. The thin part a of the first critical line 16 and the second critical line 17 may be formed to have the same thickness width as the thin part a of the central part, but depending on the thickness, material, etc. of the peripheral wall 5, Can be formed thinner than the other part a, and can be cut more easily.
[0018]
The thin-walled portion a is for cutting the peripheral wall 5 of the main body partly together with the through-hole 18 so that the main body can be easily detached from the mouth-and-neck portion 4, and various shapes can be adopted. It is necessary that the line 17 exists at a position above the engaging protrusion 6. However, the object and effect of the present invention can be achieved even if the pole portion of the second critical line 17 may be located below the engaging protrusion 6. Further, in order to make the thin portion a particularly easy to cut, the second critical line 17 is formed so as to bend downward from the upper end of the peripheral wall 5 and then bend downward and then spirally extend.
[0019]
The installation length of the second critical line 17 is not particularly limited. However, the base end originates on one side of the upper end of the main body peripheral wall 5 and extends to the side. If it is provided with a length of about 1/2, the cap can be removed from the mouth and neck part relatively easily, and it can be stably attached to the mouth and neck part 4 even when there is a thin part a during use. I can do it. It is also possible to extend the second critical line 17 around the peripheral wall to the first critical line 16.
[0020]
When such a cap A is used, the pull ring 13 is pulled to cut the portion of the cutting line 10 and the cut lid 11 is removed and used. In this case, sufficient engagement strength between the locking protrusion 7 and the engaging protrusion 6 is provided to prevent the cap from being removed due to the liquid pressure of the poured liquid. Further, when discarding the liquid stored in the container after use, a tool 19 such as a metal plate is inserted from above the through-hole 18, and as shown in FIG. The critical line portion is cut, and then the peripheral wall 5 is cut from the second critical line 17 as shown in FIG. At this time, the cover 3 can be held by hand. When the second critical line 17 is cut to a certain extent, the cap A can be easily removed from the mouth-and-neck portion 4. As shown in the figure, when the through-hole 18 is present in the thin hinge 15 portion, without using the tool 19 as described above, the lid 3 is directly held down by hand and pulled backward. Similarly, each critical line can be cut.
[0021]
【The invention's effect】
As described above, the cap of the present invention has the first critical line 16 that cuts the peripheral wall 5 vertically, and the upper position of the engaging ridge 6 after being lowered from the upper end position of the peripheral wall 5 that is separated from the upper end of the first critical line 16. The peripheral wall 5 between the first critical line 16 and the second critical line 17 extending to the opposite side is formed thin, and penetrates the edge of the top plate 8 between the first critical line 16 and the second critical line 17. Since the through-hole 18 having a lower end opened in the gap between the peripheral wall thin portion a and the neck 4 is formed so that the thin portion a can be cut from each critical line portion, In order to prevent inconveniences such as the cap coming off due to the fluid pressure flowing out into the container mouth neck when the container is tilted, engage the locking ridge and the engagement ridge with sufficient engagement strength. Even if it prevents accidental disconnection, it can be removed from the container body with a simple operation after using the stored liquid. It is obtain things.
[0022]
In the case of the cap according to the second aspect of the present invention, there is an advantage that the thin portion can be broken by holding the lid by hand without using a tool such as a metal plate.
[0023]
In the case of the cap according to the third aspect of the present invention, there is an advantage that the thin portion can be easily cut without difficulty.
