[0001]

[Industrial applications]

 This invention relates to the inner lid of a container used for a container such as a bottle for storing various liquid products.

[0002]

[Prior art]

 Conventionally, a container inner lid as shown in FIG. 4 has been used. Since this invention relates to an improvement of the inner lid as shown in the figure, the above-mentioned conventional inner lid will be described first. In the figure, a is an inner lid made of synthetic resin, and is fitted into the mouth portion c of the container b. Reference numeral d denotes an outer cylinder, and an inner cylinder e and an upper wall f form a mounting portion g formed by the three members d, e, f, and the mouth portion c is sandwiched and fitted. Reference numeral h denotes a protrusion-shaped engaging portion, which is engaged with the concave hooking portion i of the mouth portion c. j is a mounting portion, k is a pouring tube, l is a mouth wall formed inside the inner cylinder c, and an endless fissure groove m is formed in this. Reference numeral n denotes a tearing member provided inside the fissure groove m of the mouth wall l.

Incidentally, p is an outer lid, which is attached to the attachment portion j of the inner lid a. Further, the lower end portion q of the outer cylinder d is covered by the protrusion r of the container b protruding outward. Since the inner lid is formed in this manner, the inner lid is kept closed until the first opening, and the lower end q of the outer cylinder d is covered by the projection r, so that the finger or the like is not attached to that portion. Since it is not possible to apply force to the upper part by putting in, it is impossible to illegally refill at the distribution stage.

[Problems to be solved by the device]

 However, the above conventional inner lid has the following problems. After consuming liquid products (not shown) in the container b, the container b may be collected as a resource without being discarded.

In such a case, since the material of the inner lid a is usually different from that of the container b, it is necessary to separate the both a and b. Specifically, the inner lid b is removed from the container a. However, since the inner lid b is fitted as shown in the drawing and the engaging portion h is engaged with the hooking portion i, it cannot be easily removed.

Therefore, the container a is not smoothly collected. The present invention has been made to solve such a problem, and its purpose is to ensure that the inner lid of the above-mentioned type is always firmly attached to the mouth of the container and therefore cannot be easily removed. When the container b is attached and the contents of the container b are consumed and the container b is recovered as a resource, the inner lid of the container that can be easily removed from the container b is used. Is to provide.

[0007]

[Means for Solving the Problems]

 The inner lid of this container that achieves the above-mentioned object will be described. It is made of synthetic resin and has a convex engaging portion 1 that engages with a concave hooking portion formed on the outer periphery of the mouth of the container. Outer cylinder 2; Inner cylinder 3 concentrically provided inside the outer cylinder 2; Upper wall 4 that integrally connects both upper ends of the outer cylinder 2 and the inner cylinder 3; A holding portion 4a for holding the rim of the container; a mounting portion 6 for screwing or locking an outer lid 5 provided on the upper wall 4; provided inside the mounting portion 6 Injection pipe 7; mouth wall 8 provided inside the inner cylinder 3; endless fissure 9 formed in the mouth wall 8; provided on the mouth wall 8 inside the fissure groove 9 Tearing member 10; thin-walled portion 11 provided inside the outer cylinder 2 and above the engaging portion 1; shaped upward from a part of the lower end of the outer cylinder 2 and reaching the thin-walled portion 11. Weakening line 12 which is; a lid in a container, characterized in that it consists of; in response to weakening line 12, knob 13 provided at the lower end of the outer tube 2.

[0008]

[Action]

 A user such as a consumer removes the outer lid 5 from the mounting portion 6 of the outer lid 5, then pulls the tearing member 10 upward, tears the tear groove 9, and forms a passage therethrough, which is not shown. Pour out the product and use it. When the same contents are consumed and the container is to be recovered as a resource, the knob 13 is pinched and an upward force is applied to tear off the weakening line 12, and thus the one of the engaging portions 1 is broken. Tear off the part. Then, the pressure contact force of the holding portion 4a is greatly reduced.

Therefore, in this state, if the outer cylinder 2 is grasped from the outside and pulled up, the inner lid a can be extracted from the container very easily. Thereby, this container can be easily recovered.

[0010]

【Example】

 In FIG. 1, reference numeral 2 denotes an outer cylinder made of synthetic resin, which has a convex engaging portion 1 that engages with a concave engaging portion 17 formed on the outside of a mouth 16 of a container 15 such as a bottle. There is. Reference numeral 3 denotes an inner cylinder, which is concentrically formed inside the outer cylinder 2, connects the upper ends of both cylinders 2 and 3, and is integrally provided with an upper wall 4. Reference numeral 6 denotes an attachment portion to which the outer lid 5 is attached, and the attachment method may be screw engagement or engagement.

Reference numeral 7 is a pouring cylinder provided on the upper wall 4, and 8 is a mouth wall formed inside the inner cylinder 3 for blocking the flow of liquid and the like, which has an endless shape. A fissure 9 is formed. Reference numeral 10 is a pull ring-shaped tearing member provided on the mouth wall 8 and inside the fissure 9.

Reference numeral 11 is a thin portion formed inside the outer cylinder 2 and on the engaging portion 1. A weakening line 12 reaching the thin portion 11 is formed above the lower end of the outer cylinder 2. Two weakening lines 12 are shown as shown in FIG. 2, and the two weakening lines 12 are connected to the thin portion 11 at the upper part. However, there is no difference even if the number of weakening lines 12 is one as shown in FIG.

Next, reference numeral 13 is a knob, which may be formed so as to project as shown in FIG. 2, or may be formed by forming a notch 13a as shown in FIG. Absent. Since the operation of this embodiment is substantially the same as the operation of the present invention described above, the description thereof will be omitted.

[0014]

[Effect of device]

 Since the invention is formed as described above, the container mouth is normally closed tightly, and when the contents of the container are consumed and the container is recovered as a resource, the knob By grasping 13 and pulling it and tearing the weakening line 12, the convex engaging portion 1 can be torn off and the pressure contact force against the container can be weakened. Therefore, the inner lid can be easily removed from the container. You can Therefore, the container can be easily collected as a resource.
