Description

  The present invention relates to a cup-shaped container that can easily drink a beverage.

  After filling a cup-shaped container body with a beverage, a beverage-filled cup-shaped container is commercially available in which the inside of the container is sealed by adhering a seal lid to the flange of the lip of the cup-shaped container body. A person who has purchased a cup-shaped container filled with a beverage can easily drink the beverage by piercing a straw into the sealing lid when the content beverage is at room temperature or cold. However, when the beverage is hot, it cannot be drunk with a straw, so the seal lid must be peeled off and the lips must be in direct contact with the flange to drink the content. However, the flange exists as a protrusion on the lip of the container, and the flange surface is roughened by the adhesive remaining on the seal lid, etc. Feel uncomfortable when the person puts his lips.

  In order to solve such problems, an overcap having an opening member has been proposed (for example, see Patent Documents 1 and 2). In this overcap, an opening member having a cutting blade is formed integrally with the overcap, and a hinge is provided between the opening member and the overcap. The overcap is placed on the cup-shaped container body from above the seal lid in advance, and the lower end of the overcap is fitted with the flange of the cup-shaped container body. The seal lid can be broken by pushing down and the cutting blade of the opening member. And it can drink a content drink without a sense of incongruity by applying to the clearance gap between an opening member and an overcap, without directly applying a lip to a flange.

It has. The body 5 is preferably tapered so that the diameter increases as it goes from the bottom 6 side to the flange 2 side. The flange 2 is formed as a flat ring that protrudes radially outward from the rim of the body 5.

  The seal lid 3 is configured as a circular sheet having an outer diameter slightly larger than the outer diameter of the flange 2 of the cup-shaped container body 1. The seal lid 3 is bonded to the flange 2, and the outer peripheral portion protrudes from the outer periphery of the flange 2 without being bonded to the flange 2. On the outer periphery of the seal lid 3, a knob 3a protruding from one place is integrally provided.

  The seal lid 3 is configured as a laminated body having a layer structure of base material layer / barrier layer / easy peel layer, for example. The base material layer is used to give the seal lid 3 hermeticity, waist strength, and the like, and is formed of, for example, PET or a polyamide resin film. Desired items are displayed on the inner surface of the base material layer by printing. The barrier layer imparts gas barrier properties to the seal lid 3, and is formed of a film such as aluminum foil, vapor-deposited PET, or EVOH (ethylene-vinyl alcohol copolymer resin). The easy peel layer is for heat-sealing the sealing lid 3 to the cup-shaped container and for easily peeling the sealing lid 3 from the container during drinking. The easy-peel layer is laminated by coating or EC (extrusion coater). Alternatively, an easy peel film may be bonded and laminated by dry lamination or the like.

  The seal lid 3 is punched in advance as a disc having the knob 3a from the material sheet having the layer structure.

  The seal lid 3 is placed on the lip of the cup-shaped container body 1 after being filled with the beverage A so that the heat-sealant layer is in contact with the flange 2, and then, for example, pressing with a heating plate or ultrasonic waves It adheres to the flange 2 by welding.
