Abstract

(57) [Abstract] [Purpose] A container made of synthetic resin is used to hold the mouth of a container between an inner cylinder and an outer cylinder, and a protrusion-shaped engaging portion on the inner surface of the outer cylinder is engaged with a concave locking portion on the outer periphery of the mouth. In order to facilitate the recovery of the container as a resource, in a container lid of a type in which an endless fissure groove is provided on the mouth wall that blocks the passage of fluid and a tearing member is provided on the mouth wall, Providing a container lid that is extremely easy to remove from the container. [Structure] A fissure groove is provided on a wall of an inner plug that holds a container mouth portion between an outer cylinder and an inner cylinder to block a fluid passage, and a protrusion-shaped engaging portion on the inner surface of the outer cylinder is formed into a concave shape of the container. The outer plug of the outer cylinder was fitted with the inner stopper 11 having a weakening line in the vertical direction, and the inner stopper and the outer lid for covering the inner stopper were attached to the container.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a container lid that is used by being attached to the mouth of a container such as a bottle.

[0002]

[Prior art]

 Conventional containers such as bottles may be recovered after use of the contents and reused as resources. In this case, remove the lid attached to the container and collect only that container. This is because the container and lid usually use different materials, so the lid must be removed beforehand so that the materials do not mix.

[0003]

[Problems to be solved by the device]

 However, when removing a lid from a container such as a bottle as described above, the current lid is generally fitted by tightly sandwiching the mouth of the container from inside and outside, and cannot be easily removed. The present invention was made in order to solve such a problem, and the purpose thereof is that the container is usually firmly fitted in the mouth of the container, and when the container is collected, it is extremely easy to open the container mouth. To provide a lid for the container that can be removed from the compartment.

[0004]

[Means for Solving the Problems]

 This invention which achieves the above-mentioned object will be described as follows: an inner plug 1 made of a synthetic resin and attached to the mouth of a container; an inner cylinder 2 and an outer cylinder 3 attached to the inner plug 1. Part 4; Protrusion-like engaging part 6 formed on the inner surface 5 of the outer cylinder 3 for engaging with the concave locking part of the container mouth part; Blocking passage of fluid formed in the inner plug 1 Mouth wall 7; endless fissure 8 formed in the mouth wall 7; tearing member 9 provided on the mouth wall 7 inside the fissure 8; provided in contact with the outer surface 10 of the outer cylinder 3. A synthetic resin inner plug 11; a vertical weakening line 12 formed on the inner plug 11; an outer lid 13 that is attached to cover both the inner plug 11 and the inner plug 1. It is a container lid characterized by that.

[0005]

[Action]

 A user such as a consumer first removes the outer lid 13, then cuts the tear groove 8 using the tear member 9, forms a through hole therein, and then pours out the contents of the container. use. Next, when the contents of the container are consumed and the container is recovered, the recovery worker first removes the outer lid 13 to remove it, and then the inner plug 11 , Are torn by the weakening line 12 in the vertical direction and removed.

Then, the outer cylinder 3 of the inner plug 1 appears. The engagement of the engagement portion 6 of the outer cylinder 3 with the locking portion of the container is such that the inner plug 11 is provided so as not to be disengaged outside, that is, so as not to be elastically deformable. However, the engagement by the engaging portion 6 causes the mouth portion to be clamped more weakly than the conventional one due to the provision of the inner stopper 11, and therefore, after the inner stopper 11 is removed, The inner plug 1 can be easily removed from the mouth.

[0007]

【Example】

 In FIG. 1, reference numeral 1 denotes an inner plug, which is made of a synthetic resin, and is fitted by sandwiching an opening 16 of a container 15 by an inner cylinder 2 and an outer cylinder 3. An inner surface 5 of the outer cylinder 3 is provided with an engaging portion 6 that engages with a concave engaging portion 17 formed on the outer surface of the mouth 16 of the container 15.

Reference numeral 7 denotes a mouth wall integrally formed inside the mounting portion 4 for blocking passage of fluid, and an endless fissure groove 8 is formed in the mouth wall 7. Reference numeral 9 denotes a pull ring-shaped tear member provided on the mouth wall 7 inside the tear groove 8. Reference numeral 18 is a pouring tube. Next, 11 is a synthetic resin inner plug, which is formed as shown in FIG. 2 and FIG. 3, and is provided with a ring 21 on a tubular main body 19 via a connecting piece 20 which is easy to tear. It is provided in contact with the outer surface 10 of the inner plug 1, which prevents the inner plug 1 from elastically deforming for some reason and coming off the mouth portion 16, that is, as a pressing member. It is installed.

Reference numeral 14 is a convex engaging portion provided on the inner surface of the inner plug 11, and is engaged with the concave inner surface of the engaging portion 6 of the inner plug 1. Next, 12 is a weakening line formed on the inside plug 11 in the vertical direction of the inside plug 11, and is formed by, for example, perforations formed in the groove.

However, there is no problem even if this weakening line is formed by a fissure. In addition, it may be a small hole or the like provided continuously, or may be formed by a combination thereof, and any type may be used as long as it is easy to tear and a weakened line is formed. Reference numeral 22 is a tearing portion following the ring 21. Next, 13 is an outer lid, which is made of synthetic resin as an example, is attached to the container 15 while covering the inner plug 1 and the inner plug 11, and is screwed as an example.

The inner plug 1 is formed so that its outer periphery is covered with the inner plug 11 as described above to prevent elastic deformation and is difficult to remove as it is. Since the tube 3 is provided with the inner plug 11, it is formed to be slightly thinner than the conventional inner plug of the same kind, and therefore, the inner plug 1 itself is easier to remove than the conventional one.

The operation of this embodiment is almost the same as the operation of the present invention described above, but a user such as a consumer first removes the outer lid 13 and pulls the tear member 9 upward to remove the tear groove 8. The container is torn and a through hole is formed therein, the container 15 is tilted, and the contents are poured out from the pouring tube 18 for use.

When the contents are consumed, the container 15 is recovered as a resource. In that case, the recovery operator first removes the outer lid 13, then picks up the ring 21 of the inner plug 11 and pulls it in the direction of arrow A21, as shown in FIG. Then, by pulling in the direction A12, the weakening line 12 is cut off and the inside plug 11 is removed.

Then, the outer cylinder 3 of the inner plug 1 appears. Since the outer cylinder 3 is pressed from the outside by the inner plug 11, the outer cylinder 3 can be formed to be a little thinner than the conventional outer cylinder of the same kind, and accordingly, can be formed to be a little thinner, and Although the elastic deformation was suppressed by the inner plug 11, it can be elastically deformed to the outside by removing the inner plug 11, so that it can be elastically deformed and easily pulled out upward. The lid can thus be easily removed from the container 15.

[0015]

[Effect of device]

 The present invention is configured as described above, so that when removing the lid from the container to which the lid is attached, the outer lid 13 is removed, and the weakening line 12 of the inner plug 11 is cut to remove the inner plug 11. . With this configuration, the inner plug 1 can be formed to be elastically deformed outward more easily than the conventional one, and thus, the inner plug 1 can be easily withdrawn while elastically deforming. Therefore, the lid is usually tightly fitted to the mouth of the container, and the lid can be removed from the container 15 very easily when the container is recovered.
