るものである。 First, in the embodiment shown in FIG. 2 and FIG. Two to three uneven ribs 13 are provided concentrically, and molded resin parts 11 such as polyethylene are molded on both sides near the periphery of the lid base material 8 by injection molding, except for the rib 13 portion, and A molded resin portion 1 is provided on both sides of the portion where the opening tab 12 comes into contact with the molded resin portion 11 inwardly and away from the molded resin portion 11.
1', 11', and a hinge part 1 made of thin resin between the molded resin part 11'' located approximately 180° opposite the opening tab 12 and the outer molded resin part 11.
5, and an uneven rib 14 for adhesion is formed on the molded resin part which is the adhesive part to the container body.
次に第４図、第５図に示す実施例においては、
開封用タブ１２が、蓋の凹陥部を形成している傾
斜面１７に設けられている場合であり、その他の
構造は第一の実施例と同様であるので説明は省略
する。 Next, in the embodiment shown in FIGS. 4 and 5,
This is a case in which the opening tab 12 is provided on an inclined surface 17 forming a concave portion of the lid, and the other structure is the same as that of the first embodiment, so a description thereof will be omitted.
さらに第６図、第７図に示す実施例において
は、第一、第二の実施例と異なり、開封用タブ１
２に当接する個所だけでなく、第７図に示すよう
に円周状に設け、かつヒンジ部１５を除いたもの
である。 Furthermore, in the embodiment shown in FIGS. 6 and 7, unlike the first and second embodiments, the opening tab 1
2, but also in a circumferential manner as shown in FIG. 7, excluding the hinge portion 15.
本考案の容器蓋の各実施例の製造方法について
簡単に説明すると、何れの場合も、凹陥状の蓋基
材８の両面に例えば射出成形法により、成形樹脂

円状の凹凸状のリブ１３は前記成形樹脂部の成形
と同時または予め形成しておく。 To briefly explain the manufacturing method of each embodiment of the container lid of the present invention, in each case, molded resin parts 11, 11', 11'', 11. Simultaneously mold the hinge portion 15 and the uneven ribs 14 for adhesion,
The opening tab 12 is attached to the molded resin part 11' or 11.
Glue on top. Note that the concentric ribs 13 in the vicinity of the center of the lid base material 8 are formed at the same time as the molding of the molded resin part or in advance.
次に本考案の使用方法を説明すると、第２図、
第４図の実施例の場合は、共に開封用タブ１２を
起こすことにより該タブ先端の爪１８，１８′で
蓋基材８の部分を破つて開封のきつかけを作り、
次いで開封用タブ１２を引つぱつて持ち上げれ
ば、前記爪１８で破られた個所をきつかけとして
蓋基材８がヒンジ部、１５，１５′の所までほぼ
円周状に破断される。 Next, to explain how to use the present invention, Fig. 2,
In the case of the embodiment shown in FIG. 4, by raising both the opening tabs 12, the claws 18, 18' at the tips of the tabs tear the lid base material 8 to create a tight opening.
Next, when the opening tab 12 is pulled and lifted, the lid base material 8 is torn in a substantially circumferential shape up to the hinge portions 15 and 15', using the portion torn by the claw 18 as a trigger.
このとき、開封された蓋はヒンジ部１５，１
５′で蓋の外周部と結合されているので容器内に
落ちることがない。 At this time, the opened lid is attached to the hinge portions 15 and 1.
Since it is connected to the outer periphery of the lid at 5', it will not fall into the container.
なお、このとき、爪１８，１８′と対向する成
形樹脂部に凹部１９，１９′をそれぞれ設けてお
くと、蓋基材８が破れ易くなる。 At this time, if recesses 19 and 19' are provided in the molded resin portions facing the claws 18 and 18', respectively, the lid base material 8 will be easily torn.
また、第６図の実施例においても基本的には同
様であるが、この場合は開封部１６の蓋基材８に
円周状に成形樹脂部があるので開封用タブ１２を
ひつぱつて持上げると蓋基材８が円周状に取除か
れ、開封される。このとき、開封部１６と傾斜部
１７の間につなぎ２０を設けておけば開封した
後、蓋が容器内に落ちることがない。 The embodiment shown in FIG. 6 is basically the same, but in this case, the lid base material 8 of the opening part 16 has a molded resin part around the circumference, so the opening tab 12 can be held tightly. When raised, the lid base material 8 is removed circumferentially and opened. At this time, if a tether 20 is provided between the unsealing part 16 and the inclined part 17, the lid will not fall into the container after being opened.
〈考案の効果〉
本考案は以上のような構成になつているので次
のような優れた実用上の効果を有する。<Effects of the invention> Since the present invention has the above structure, it has the following excellent practical effects.
(イ) 蓋全体にアルミニウム等の金属箔が介在する
ため、ガスバリヤー性が優れており、常温流通
を要求される物の容器の蓋として適している。(a) Since the entire lid is covered with metal foil such as aluminum, it has excellent gas barrier properties and is suitable as a lid for containers that require circulation at room temperature.
(ロ) 開封個所は比較的薄い蓋基材だけであるので
開封が容易である。(b) Since the only part to be opened is the relatively thin lid base material, opening is easy.
(ハ) 蓋基材の片面または両面に成形樹脂部が形成
されているので強度があり、保護のための外蓋
が不要である。(c) Since the molded resin part is formed on one or both sides of the lid base material, it is strong and does not require an outer lid for protection.
(ニ) 容器本体開口部との接着面に凹凸状のリブを
設けてあるので、容器本体の側方接合部に当接
する個所も完全に接着でき、密封性が向上す
る。(d) Since uneven ribs are provided on the surface to be bonded to the opening of the container body, the portions that come into contact with the side joints of the container body can also be completely bonded, improving sealing performance.
(ホ) 蓋の中心部から同心円状に凹凸状のリブを設
けてあるので、リブの伸縮により容器内圧の変
化を吸収して、容器本体の変形を防止すること
ができる。(E) Since the lid is provided with concentric ribs extending concentrically from the center, changes in the internal pressure of the container can be absorbed by the expansion and contraction of the ribs, thereby preventing deformation of the container body.
