Problems solved by technology

Also, if hot melt layers are used, there may be hot melt cleanability issues (hot melt residue produced)
In addition, there is a problem that, if exposed to a high-temperature environment, the cup may accidentally open due to the melting of the hot-melt layer, and the odor of the hot-melt layer may lower the value (quality) of the product

Embodiment Construction

[0037] In the present application, the terms "lower", "innermost", "outer", "upper" refer to the position of components inside the cap in the context of using the cap to seal the container. Thus, this means that the "lower" and "innermost" layers of the lid are arranged closer to the interior of the container, while the "upper" and "outer" layers of the lid are arranged closer to the outside of the container.

[0038] Embodiments of applying the cap with barrier properties according to the present invention to the container 1 for refilling instant coffee will be described in detail below with reference to the accompanying drawings. The invention is primarily a lid with barrier properties to be attached to a paper cup and can be applied to all embodiments where the lid is opened by tearing. Therefore, the present invention is not limited to the structures of the following examples.

[0039] First, if image 3 , Figure 4 As shown, the refill container 1 comprises a tubular c...

Abstract

The invention relates to a lid with barrier property having highly improved barrier property, sealing ability for cups, and ease of opening in comparison with the conventional products. The innermost layer is a resin layer including a polyethylene sealant layer, and a metal foil layer is attached to the outside of the resin layer of the innermost layer via an adhesive layer. The innermost layer is provided with a plurality of weakened portions extending radially from the center. The weakened portions facilitate tearing the innermost layer and also the metal foil layer, thereby facilitating opening of the lid.

Description

technical field [0001] The invention relates to a lid to be attached to the mouth of eg a paper cup, the lid having a laminated structure consisting of metal foil and plastic foil. Specifically, the present invention relates to a lid that can be attached to and seals a paper cup to maintain barrier properties and can be easily opened by squeezing and tearing. Background technique [0002] A number of tear-opening lids have been developed and are commercially available, such as those that are opened by piercing them with a straw. Furthermore, many proposals have been made to attempt to assist opening of the lid by perforations, break lines or score lines. Usually, the lid of the paper cup is designed to have a thick sealing layer on the innermost layer to cover the step, so that when the lid is attached to the paper cup, the lid can seal the step on the flange or curl of the paper cup. For paper cups, roll rectangular paper into a cylinder, or fan-shaped paper into an upsid...
