[Structure] In a device in which an inner lid and an outer lid made of synthetic resin are sequentially inserted into a container opening, a locking protrusion provided on an inner periphery of a lower edge of a side wall of the outer lid is irremovably tightly fitted into an annular groove of the container opening. Then, a container sealing device in which the close-fitting release means is provided on the outer lid.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a container sealing device for sealing a container opening with an inner lid and an outer lid made of synthetic resin.

[0002]

[Prior art]

 BACKGROUND ART Conventionally, there is widely known a technique in which an outer lid is tightly fitted to a container mouth and a closure is fitted to the outer side of the outer lid.

Also known is a sealing device having a structure in which a closure is connected to the lower edge of a metal screw lid, and the lid and the closure are separated by strongly twisting the upper part of the metal lid when the lid is opened. There is.

[0004]

[Problems to be solved by devising]

 In the conventional sealing device, the lid and the sealing are separate bodies, and the sealing does not improve the sealing performance. In addition, the synthetic resin lid may be metal-sealed.

Next, since the lid is made of metal, it is necessary to construct a sealing means (for example, packing is attached) in the metal lid in which the lid and the seal are integrated. Since the lower edge of the sealing part has to be deformed and brought into close contact with the container mouth wall, there is a problem that the covering process tends to be complicated.

[0006]

[Means for Solving the Problems]

 However, the present invention solves the above-mentioned conventional problems by making the inner and outer lids made of synthetic resin, imparting a sealing function and a sealing function to the outer lid, and integrating the inner and outer lids by fitting.

That is, this invention is an apparatus in which an inner lid and an outer lid made of synthetic resin are sequentially fitted to the container opening, and a hooking protrusion provided on the inner periphery of the lower edge of the side wall of the outer lid is provided with an annular groove of the container opening. A sealing device for a container, characterized in that it is non-detachably tightly fitted to the outer lid, and that the means for canceling the tight fitting is provided on the outer lid. Further, the means for releasing the close fitting is to provide a cut piece from the side wall or the upper wall of the outer lid to the side wall, and to continuously connect the cut piece to the outer lid wall. The inner lid is fitted and integrated into the outer lid. In addition, the knob is housed flush with the outer lid.

The device of the present invention may be used for either a bottle mouth or a can mouth. In the case of a bottle, glass or synthetic resin may be considered, and in the case of can, metal or synthetic resin may be considered. Be released.

In the above description, it is preferable that the knob piece is in contact with the outer wall and keeps the state, so that it is possible to insert the projection of the knob piece into the hole of the outer lid. However, if they are accommodated in the same plane, it is possible to maintain the correct position even by fitting the knob and the recessed part.

[0010]

[Action]

 In this invention, since the outer lid is tightly fitted and the releasing means is provided, the container is sealed when tightly fitted, and after releasing the sealing, the container mouth is tightly fitted by the inner lid.

[0011]

Embodiment 1 An embodiment of the present invention will be described with reference to the drawings.

The dispensing tube 2 made of synthetic resin is fixed to the opening of the top plate 1 of the can, and the inner lid 3 made of synthetic resin is capped on the dispensing tube 2 to cover the inner lid 3 The protrusion 4 on the inner side of the lower edge is engaged with the edge of the annular groove 5 provided on the outer side wall of the spout tube 2. The inner lid 3 is capped with an outer lid 6 made of synthetic resin, and the ridge 7 on the inner side of the lower edge of the outer lid 6 is engaged with the edge of the annular groove 5. The outer lid 6 and the inner lid 3 can be fitted to the pouring tube 2 at the same time in a state where they are fitted to each other in advance. In this way, the outer lid 6 cannot be removed if it is fitted as shown in FIG. Cut lines 8, 8a are obliquely provided on the side wall of the outer lid 6, and at least one of the cut lines reaches the lower edge of the outer wall of the outer lid, and the cut pieces 9 are provided on the cut pieces 9 between the cut lines 8. Are provided in series, and a projection 11 is provided on the inner side of the distal end of the knob 10 (FIG. 3 (a)). The projection 11 is fitted and locked in a small hole 12 provided in the side wall of the outer lid 6 ( Figure 3 (a)). In addition to the above-described embodiment, as shown in FIGS. 4 (a) and 4 (b), cut lines 8 and 8a are provided from the top of the outer lid 6 to the side wall, and the cut piece 9 is connected to the knob piece 10. But it has the same effect. Also in this case, the projection 11 of the knob 10 and the fitting and locking of the small hole 12 are the same as in the above example. Reference numeral 13 in the figure is a knob for the inner lid.

In short, in order to release the engagement between the protrusion 7 on the inner side of the lower edge of the outer lid 6 and the annular groove edge of the pouring tube 2, a part of the side wall of the outer lid 6 is cut and sealed. It works.

[0014]

Second Embodiment The embodiment of FIG. 5 is the same as the above-described embodiment in that the outer lid 6 is provided with cut lines 8 and 8a, and the cut piece 9 is provided with a gripping piece 10. A concave portion 13 corresponding to the knob 10 is provided on the top wall of the outer lid 6, and a small hole 12 is formed in a part of the concave portion 13 so that the projection 11 of the knob 10 is fitted into the small hole 12. The knob piece 10 is fitted into the recessed portion 14. In the case of this embodiment, since the knob 10 is housed flush with the outer lid, there is no problem in handling the outer lid 6. Further, by fitting the recessed portion 14 and the knob piece 1 into each other, the protrusion 11 and the small hole 12 can be omitted.

[0015]

Third Embodiment In this embodiment, as shown in FIG. 6, the inner lid 3 and the outer lid 6 are fitted to the mouth of the bottle 15 in place of the can of the first embodiment. Therefore, since the effect of the sealing is the same, a detailed explanation is omitted.

[0016]

[Effect of device]

 According to this invention, the inner and outer lids are fitted and locked, and the outer lid is provided with the sealing release means. Therefore, the outer lid has an effect of both sealing and sealing. However, since the inner and outer lids are crowned at the same time, they are the same as when a single lid is crowned, which is simple and easy. If the tab is abutted on the outer lid and locked, it will not interfere with handling.
