の考案について説明する。2. Description of the Related Art The inventor of the present invention previously devised a lid of the same kind as shown in FIG. 5 and filed a utility model registration application.
(Practical application No. 3-100705). Since the present invention is an improvement of the above-mentioned applied invention, the above-mentioned applied invention will be described first.

はその容器ｌに対する取付部を示す。In FIG. 5, a is a lid made of synthetic resin, for example, an inner lid. Further, b is a pouring tube member of the lid a, which is made of polyethylene terephthalate, and c in the member b is a pouring tube for pouring out the liquid or the like in the container l,
Indicates a mounting portion for the container l.

設けられた摘み部ｇとから成っている。The mounting portion d forms a mounting portion for the bottle mouth as an example, but it may be formed in a flange shape when mounting on a carton or the like although not shown in the drawings. Reference numeral e is an opening member, which is made of synthetic resin, for example, polyethylene, and is composed of a blocking wall f and a knob portion g provided on the blocking wall f.

られている。なおｊは外蓋ｋとの螺合部である。Next, h is a projection-like engaging portion formed inside the injection pipe c, and i is a concave engaging portion formed on the outer periphery of the blocking wall f, which is the engaging portion. It is engaged with the portion h. In addition, j is a screwing part with the outer lid k.

る。そうして容器ｌの内容品を注出し、使用する。The lid of the container thus formed is attached to the container l, and when opened, the outer lid k is removed, then the knob g is picked, and this is pulled upward to engage with the engaging portion h. The engagement with the part i is released, the opening member e is removed, and the opening is performed. Then, the contents of the container 1 are poured out and used.
【０００７】この蓋の開口は上記掛合部ｉの掛合を外す
だけでよいので、この部分を引き裂かねばならなかった
従来の蓋よりも容易に開口することができる。Since the opening of this lid only needs to remove the engagement of the engaging portion i, it can be opened more easily than the conventional lid which must tear this portion.

とである。However, the lid of the above-mentioned container has the following problems. It is a pouring member b
If there is a difference in contraction rate between the opening member e and the opening member e, the sealing is reduced in the engagement of the engaging portion h and the engaging portion i.

縮率が大きく、そのため収縮により上記係合部ｈと掛合
部ｉとの掛合において、同掛合箇所が僅かであるが、間
隙を生じ、密封が損なわれてしまうのである。Generally, the difference in shrinkage ratio of synthetic resins is caused not only by different kinds of synthetic resins but also by the same kind of resins due to the difference in molecular weight and the like. Further, in the case of the above-mentioned applied container, the polyethylene opening member e has a larger shrinkage rate than the polyethylene terephthalate injection cylinder member b, and therefore, the contraction of the engagement portion h and the engagement portion i due to the shrinkage is the same. Although there are few engagement points, a gap is created and the seal is impaired.

容器の蓋を提供することである。The present invention has been made to solve the above problems, and its purpose is that the opening member e has a difference in contraction rate between the members b and e, and the opening member e has a smaller shrinkage ratio than the casting cylinder member b. It is an object of the present invention to provide a container lid in which the sealing between both members b and e is not impaired when the contraction rate is large.

に向って収縮する。The lid of the container of the present invention is constructed as described above,
When contraction occurs, and when there is a difference in contraction rate between the casting cylinder member 3 and the opening member 7, and the opening member 7 has a larger contraction rate, the opening member 7 has a radius equal to that of the opening member 7. Contract toward the center of the.

容器の蓋の問題点が解決された。Then, the hooking portion 7 of the opening member 7 also contracts in the same central direction, and in this case, the locking portion 4 of the casting cylinder member 3 also contracts in the radial central direction, but the above hooking portion rather than the contraction. 8
Since the contraction rate of the
It is possible to prevent the deterioration of the airtightness as a result of further strengthening of the engagement and the stronger pressure contact. In this way, the problem of the above-mentioned applied container lid is solved.

The mounting portion 1 may be formed so as to be attached to the mouth portion 11 of the bottle as shown in 10 of FIG. 3, or 1 in FIG.
It may be formed in a flange shape as shown in FIG.

図において１４は図示しない外蓋との螺合部である。In FIGS. 1 and 2, reference numeral 4 denotes a locking portion, which is formed so as to lock with a locking portion 8 described later in the radial direction. Reference numeral 13 denotes a downward protrusion. In the figure, 14 is a threaded portion with an outer lid (not shown).

に形成されており、１５は上向き突起を示す。Next, 7 is an opening member made of synthetic resin, for example, polyethylene, and is composed of a blocking wall 6 and a knob 5 provided on the upper portion thereof. The knob 5 is formed in a pull ring shape as an example. Reference numeral 8 denotes a hooking portion, which is formed so as to hook with the locking portion 4 in the radial direction, and 15 indicates an upward protrusion.

よって収縮率に差の生じる場合が有るからである。The injection cylinder member 3 and the opening member 7 are made of different synthetic resins as an example, but they may be made of the same kind of synthetic resin. This is because even if the same kind of synthetic resin is used, the shrinkage ratio may differ depending on the molecular weight and other molding conditions.

Next, FIG. 4 shows another embodiment of the present invention, in which the locking portion 4 is formed upward, the latching portion 8 is formed downward, and both 4 and 8 are arranged in a radial direction. Are hanging on each other. Even in such a mode, it does not matter. Since the operation of this embodiment is almost the same as the operation of the present invention described above, the description thereof will be omitted.

防止することができる。Since the present invention is configured as described above, there is a difference in contraction rate between the pouring tube member 3 and the opening member 7, and the opening member 7 has a contraction rate higher than that of the pouring tube member 3. When both of them are large, the both parts 3 and 7 are locked to each other in the radial direction in the locking part 4 and the locking part 8 even if they contract, so that the pressure contact of those parts is strengthened, resulting in a decrease in the hermeticity. Can be prevented.
