【考案の詳細な説明】
本発明は液体飲料等の蓋体に関するものであり、詳しく
は紙等の比較剛性のある材質をもって円板上の蓋体天板
とし、該天板１１にプルタブと称する開口用引張片を有
する容易開封容器の蓋体である。[Detailed description of the invention] The present invention relates to a lid for liquid beverages, etc., and more specifically, a lid top plate on a disc is made of a comparatively rigid material such as paper, and the top plate 11 is provided with a pull tab. This is a lid for an easy-to-open container that has a pull piece for opening.
従来プルタブ式の容易開封容器の蓋体は種々のものがあ

開封容器は金属製であるにも拘らず缶切り等の道具を用
いることなく開口可能であり、手軽である故、今日極め
て多くの容器が容易開封容器とされている。There are various types of lids for conventional pull-tab-type easy-open containers, but in general, the lid is made of metal with a notch called a score to define an opening piece, and a tension piece called a pull tab is riveted to the opening piece. Although easy-open containers are made of metal, they can be opened without using tools such as a can opener, and because they are easy to open, many containers today are considered easy-open containers. ing.
ところで、この容易開封容器においては内容物が液体で
ある場合には容器開口部に口を直接付けて飲食すること
が多く、開口部周辺を衛生的にすることが望まれていた
。By the way, when the contents of this easy-to-open container are liquid, people often eat or drink by touching the mouth directly to the opening of the container, so it has been desired to keep the area around the opening hygienic.
しかし、容易開封容器では開口部分周辺のみを衛生的に
保つことが困難であり、容器上面全体を合戊樹脂製薄膜
体のキャップをもって覆い、開口部を含む蓋体全体を清
浄としていたが、この様な合戒樹脂製薄膜体のキャップ
を用いる場合には容器の移送、保管時にキャップが外れ
ることがあり、又容器の開封時にはキャップを外した後
、プルタブを引き起す二度手間が必要である等の欠点が
あった。However, with easy-to-open containers, it is difficult to keep only the area around the opening sanitary, so the entire top surface of the container is covered with a cap made of a thin synthetic resin film to keep the entire lid including the opening clean. When using a cap made of a thin resin film like the one described above, the cap may come off when the container is transported or stored, and when opening the container, it is necessary to remove the cap and then pull up the pull tab twice. There were drawbacks such as.
上述の様な従来のプルタブ式容易開封容器に対し、本考
案は合金樹脂製のプルタブ及び開口部を充填する密封体

Since it is integrated with the handle 14, the opening cover 24 and sealing body 20 can be removed and the container opened by simply pulling up the handle 14, and these opening handle 14, sealing body 20, etc. can be combined. Since it is made of resin and integrally molded, it can be manufactured extremely easily by injection molding, etc., and the outer annular downward protrusion along the opening portion 12 is formed on the rigid disc-shaped top plate 11. Since the sealing body 26 is molded and added to the top plate 11, the sealing body 2 is securely and firmly attached to the top plate 11.
0 can be attached, and the outer annular lower projecting body 2
6 and the inner annular lower protrusion 27 on the lower side of the periphery of the sealing body 20, the opening can be made easy and reliable.
更に被覆ガイド２９は本考案に係る蓋体１０を容器本体

４と、内側環状下方突体２７と外側環状下方突体２６と
を一体として蓋体１０へ成形する。An inner annular lower protrusion 27 is formed below the periphery 21 of the sealing body 20, and an inner annular lower protrusion 27 is formed on the lower side of the periphery 21 of the sealing body 20.
A thin wall portion 23 is extended to the lower side of the joint 2 with the top plate 11, and an outer annular lower protrusion 26 is then formed to be joined to the back surface of the top plate 11, thereby forming a sealed body 20 with an opening handle 14. Opening cover 2
4, the inner annular lower projection 27 and the outer annular lower projection 26 are integrally molded into the lid 10.

する。However, the outer annular downward projection 26 on the outer side of the sealing body 20
The connecting portion extending from the top to the cover guide 29 is made as thin as possible to allow the cover guide 29 to be integrally formed with the outer annular lower projecting body 26, and the cover body 10 is inserted and fixed into the mouth of the container. To assist in this, when removing the sealing body 20, the thin wall portion 23 between the inner annular lower projection 27 and the outer annular lower projection 26 is torn, and the sealing body 20 is removed from the outer annular lower projection 26 and the covering guide 29. The structure shall be such that it can be easily separated from the
この様に本考案は密封体２０の全域を覆うのみでなく、
開口部分１２に近接する天板端面１３に近い周縁を覆う
から、開封前においては、天板１１周縁を含む範囲を常
に清浄に保つ利点がある。In this way, the present invention not only covers the entire area of the sealed body 20, but also
Since the periphery near the top plate end face 13 close to the opening portion 12 is covered, there is an advantage that the area including the periphery of the top plate 11 is always kept clean before opening.
そして開封引手１４と開口部カバー２４と密封体２０と
は一体に成型されている故密封体２０の除去と共に一挙
動により同時に開口部カバー２４を除去し得る利点があ
る。Since the opening handle 14, the opening cover 24, and the sealing body 20 are integrally molded, there is an advantage that the opening cover 24 can be removed simultaneously with the removal of the sealing body 20 by one action.
尚、密封体２０の周縁２１は、その内側環状下方突体２
７と接合する故局部変形せず、又天板１１の開口部分端

局部変形をしないから、リング上開封引手１４を上方に
引き上げる力は、密封体２０と天板１１との接合部２２
に集中し、接合部における破断を容易且つ確実とする。Incidentally, the peripheral edge 21 of the sealing body 20 is connected to the inner annular downward projecting body 2.
Since there is no local deformation because it joins with 7, and the end surface 13 of the opening portion of the top plate 11 does not deform locally because it joins with the outer annular lower protrusion 26 on the lower side, there is no force to pull the ring upper opening puller 14 upward. is the joint 22 between the sealing body 20 and the top plate 11
to ensure easy and reliable rupture at joints.
そして、密封体２０と天板１１との接合部２２の下側を
薄肉部２３とし、この薄肉部２３を挾んで密封体２０の
周縁２１下側及び天板端面１３下側が夫々補強用の内側

易に分断され、密封体２０を天板１１から容易に除去し
得る。The lower side of the joint 22 between the sealing body 20 and the top plate 11 is made into a thin wall portion 23, and the lower side of the periphery 21 of the sealing body 20 and the lower side of the top plate end face 13 are formed as reinforcing inner sides by sandwiching this thin wall portion 23. Since it includes the annular lower projection 27 and the outer annular lower projection 26, it is easily separated at the joint 22 when the opening handle 14 is pulled up, and the sealing body 20 can be easily removed from the top plate 11.
更に、密封体２０、開封引手１４、開口部カバー２４、
内側環状下方突体２７及び外側環状下方突体２６、被蓋
ガイド２９等が一体に適宜接続されている故、蓋体１０
