Description

TECHNICAL FIELD The present invention relates to a lid of a shaker container having powder granules or the like as its content.

Conventional technology and problems Instant coffee, powdered milk, sprinkles, various chemical seasonings, powdered cheese, powdered spices, pepper, curry powder,
In a shaker container containing table salt, sugar, bath salts, powdered medicines, powdered cosmetics, and other powder granules, the moisture (humidity) and oxygen in the air or the filled carbon dioxide and nitrogen gas are sufficient. If it is not blocked, the powder granules will not be able to withstand long-term storage such as distribution and sale due to moisture absorption, drying or oxygen permeation due to oxygen permeation, and deterioration due to outgassing. A lid with a large number of parts and a complicated sealing process was used exclusively.

Further, as a conventional technique, there is Japanese Patent Laid-Open No. 57-163641.
In the publication, a gas-permeable metal foil layer is used as an intermediate layer, and a V-groove-shaped score is provided along an opening of a lid formed by integrally bonding thick synthetic resin layers on the front and back sides. , The lid of a retort container is provided with a projecting pull top with a sharp pointed cutting edge facing the score on the upper surface of the lid, but the sharp pointed cutting edge of the pull top protruding on the surface of the lid is the handling of the can. There is a problem in that it is very dangerous and that the synthetic resin layer provided with the V-groove-shaped score must be made thick. In JP-A-59-229329 and JP-A-61-287540, a gas-permeation-resistant metal foil layer or a synthetic resin layer is used as an intermediate layer, and synthetic resin layers are integrally attached to the front and back. On the upper surface of the multi-layer composition layer formed by the above, the structure of the lid of the coffee can container or the like integrally provided with the upper resin layer is described so that the pull top having the sharply pointed cut edge does not protrude from the lid surface. But
