Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is a container for storing moisture-sensitive contents such as seaweed and tea, which has an easy-open lid that can be opened without using a device and a resealing lid that closes the opened easy-open lid. The present invention relates to a lid that is preferably used for closing.

[0002]

[Prior Art]

 An easy-open lid that can be opened without using a device is provided as shown in Fig. 3. The easily-openable lid 10 is one in which a gas barrier layer 2 is provided on the inner surface of an outer layer portion 1 made of polypropylene. As shown in FIG. 4, the gas barrier layer 2 is composed of a laminated film in which resin films 2b and 2c made of polypropylene or the like are laminated on both sides of a metal foil 2a made of Al or the like. The easy-open lid 10 is formed with a flange corner portion 3 that fits into the upper end of the mouth of the container 20 and an unsealed portion 5 defined by a weakening line 4 along the inner circumference of the flange corner portion 3. ing. The weakening line 4 is formed by cutting the outer layer portion 1 into a groove having a width of about 0.5 mm to expose the gas barrier layer 2. A tab 6 is attached to the opened portion 5 of the easy-open lid 10.

When opening the easy-open lid 10, first, one end of the tab 6 is pulled up and a part of the weakening line 4 is torn at the other end. Then, when the tab 6 is pulled up, the portion of the weakening line 4 is torn and the unsealed portion 5 is cut off to complete the unsealing.

[0004]

[Problems to be solved by the device]

 The easy-open lid 10 has been conventionally used to close a can container having a shallow bottom, but recently, it is considered to be used to close a deep container for storing seaweed, tea or the like. However, when the easy-open lid 10 is opened, as shown in FIGS. 5 and 6, a part (hereinafter, referred to as a residual piece) A of the cut gas barrier layer 2 protrudes inward of the opening 20. If the easy-open lid 10 is used to close a deep container, when the consumer puts his / her hand into the container to remove the contents of the container, the remaining pieces A of the gas barrier layer 2 are removed. There is a concern that your cut will hurt your hand.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a lid with higher safety.

[0006]

[Means for Solving the Problems]

 The lid of the present invention is provided with a metal barrier layer made of metal foil on the inner surface of the plastic outer layer, and an easy-to-open lid in which a portion to be opened which is removed by the weakening line is defined. A lid comprising a resealing lid that closes the opening of the easy-open lid, wherein the resealing lid has a portion to be fitted into the opening after removing the opened portion of the easy-open lid. This is characterized in that a push-bend convex portion that bulges outward is formed on the outer periphery of the lower portion of this fitting portion.

[0007]

[Action]

 Even if the cut pieces of the gas barrier layer project into the opening when the easy-open lid is opened, if the fitting part of the resealing lid is fitted into the opening, it will bulge outwardly here. The remaining pieces of the gas barrier layer that have been projected by the pushed bending convex portion are pushed outward.

[0008]

【Example】

 Hereinafter, the lid of the present invention will be described in detail with reference to the drawings. The same components as those of the conventional example are designated by the same reference numerals to simplify the description.

Embodiment 1 FIG. 1 shows an embodiment of a lid of the present invention, in which reference numeral 10 is an easily-openable lid and reference numeral 11 is a resealing lid. The easy-open lid 10 has the same structure as the conventional easy-open lid. The to-be-opened portion 5 of the easy-to-open lid 10 is provided deeper than the flange corner portion 3, and in the space formed by this, as shown in FIG. Is to be paid.

The resealing lid 11 is a bottomed tubular product, and the bottom side thereof is in close contact with the lower inner peripheral surface of the flange corner portion 3 of the easy-open lid 10 as shown in FIG. 1 (a). A contact portion 14 having a size is formed. Below this contact portion 14, there is a fitting portion 12 that fits into the opening of the easy-open lid 10 after removing the opened portion 5 without loosening. A push-bend convex portion 13 is formed under the fitting portion 12 over the entire circumference. The push-bend projection 12 has a mountain-shaped vertical cross-section and bulges outward. The push-bend convex portion 12 is provided so that its upper end is located at the lower end of the flange corner portion 3 when the resealing lid 11 is fitted into the easy-open lid 10. On the upper part of the resealing lid 11, a detaching tongue piece 18 protruding inward is provided.

Next, a method of using this lid will be described. First, the lid is attached to the mouth of the container in the state shown in FIG. 1 (b). When opening this container, the lid 11 for resealing is removed, and then the opened portion 5 is cut off using the tab 6 of the easy-open lid 10. When the container opened in this way is closed again, the resealing lid 11 is fitted into the opening 20 of the easy-open lid 10 as shown in FIG. To open the lid again, pull on the detaching tongue 18 of the resealing lid 11.

In the lid of this embodiment, even if the remaining piece A of the gas barrier layer 2 cut when the easy-open lid 10 is opened is projected into the opening 20 as shown in FIG. When the fitting portion 12 of the resealing lid 11 is fitted into the mouth 20, as shown in FIG. 1A, it is projected by the outwardly protruding push-bending convex portion 13 provided in the fitting portion 12. The remaining piece A of the gas barrier layer 2 is pushed outward and its cut end is directed outward. After that, even if the resealing lid 11 is removed, the cut end is directed outward as shown in FIG. 2, so that even if a person puts his / her hand in the container, the cut end of the remaining piece A of the gas barrier layer 2 is cut. It will not be touched.

As described above, according to the lid of this embodiment, even if the remaining piece A of the gas barrier layer 2 is projected and remains in the opening 20 at the time of opening, once the resealing lid 11 is attached, the cut end is touched by the hand. Therefore, even if this lid is used to close a deep container, when the consumer puts his / her hand into the container to take the contents of the container, he / she can use the cut end of the remaining piece A of the gas barrier layer 2 to cut the container. It is safe without any damage.

[0014]

[Effect of the device]

 As described above, the lid of the present invention is formed with a portion to be fitted into the opening after removing the opened portion of the easy-open lid, and bulges outward to the outer periphery of the lower portion of the fitting portion. Since it has a resealing lid formed with a push-bend convex portion, if the remaining piece of the gas barrier layer projects into the opening when the easy-open lid is opened, the resealing lid is attached to the opening. Sometimes the remaining part of the gas barrier layer that was protruding by the push-bend protrusion is pushed outward and its cut end is directed outward. Therefore, even if the lid of this invention is attached to a deep container, when the consumer puts his / her hand into the container to take the contents of the container, the lid does not damage the hand by the cut end of the gas barrier layer and is safe. It is sex.
