  FIG. 3 is an enlarged partial cross-sectional view of a portion A of FIG. 2 for explaining in detail the layer structure of the lid material and the sealing portion with the container body in one embodiment of the cup-type container with the easy-opening function according to the present invention. It is a schematic diagram.

  Similar to the example shown in FIG. 2, in the example shown in FIG. 3 as well, the lid member (10) has a double structure and includes a top seal layer (6) and a heat seal layer (9).

  When the cup-shaped container (30) is opened, the top seal layer (6) is a layer that is peeled off and separated from the container body (20), and the heat seal layer (9) is partially part of the container body (20). It is a layer remaining on the peripheral edge portion (22).

  Further, in the example shown in FIG. 3, the top seal layer (6) comprises a base film layer (1), an adhesive layer (2), a gas barrier layer (3) and a plastic film layer (4) from the outside of the container. .. Among them, the gas barrier layer (3) and the plastic film layer (4) are included in the top seal layer (6) as the gas barrier film layer (5).

  Further, the heat seal layer (9) is composed of an adhesive resin layer (7) and a sealant layer (8), all of which are laminated as a laminated body constituting the lid member (10) and the pull tab (11). ..

  The container body (20) and the lid member (10) are in contact with each other with the sealant layer (8), and the heat seal portion (31) is formed at the peripheral edge portion (22) of the opening (21) of the container body (20). The cup-shaped container is sealed.

  The heat seal layer (9) is provided with two types of half cuts, a half cut (12) provided on the edge of the opening and a half cut (13 provided along the outer periphery of the peripheral edge, respectively. ).

  The depth of these half cuts may be within the thickness of the heat seal layer (9) inside the container and does not affect the top seal layer (6) or the gas barrier film layer (5) outside the container. It should be in the range.

  When the cup-shaped container (30) is opened, the pull tab (11) can be grasped and pulled by fingers, and the lid material (10) continuous with the pull tab (11) can be peeled off from the container body (20) and opened.

  At this time, in the peripheral portion (22) of the opening (21), the heat seal layer (9) of the lid material (10) is formed by the heat seal portion (31) and half cuts provided on both sides thereof. Only the top seal layer (6) and the other heat seal layer (9) remain on the peripheral edge portion (22) of the opening (21) of the main body (20) and are peeled off.

  Each layer constituting these lid members (10) will be described in more detail while also referring to FIG.

  In the example shown in FIG. 3, the base material film layer (1) is shown as the base material of the lid member (10), but in the present invention, the lid member (10) is a plastic film, paper, metal foil. It is possible to use, for example, as a base material, a single substance thereof, or a laminate of the same with other layers.

  The plastic film is a film made of a polymer resin composition and includes, for example, polyolefin (polyethylene, polypropylene, etc.), polyester (polyethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate, etc.), polyamide (nylon-6, nylon-66, etc.), Polyimide or the like can be used and is appropriately selected depending on the application.

  Particularly, when polypropylene or polyethylene terephthalate is used as the plastic film, it is more preferable in terms of film strength and cost. In addition, when a stretched polyamide film is used, it is possible to impart puncture toughness and impact toughness to the laminate.

  The base film layer (1) can be laminated with other layers via the adhesive layer (2) to form a laminate. The layer structure, the material structure, the thickness, and the like of the laminate can be appropriately designed according to the required quality and for imparting a selective function.

  In the example shown in FIG. 3, the base film layer (1) is laminated with the gas barrier film layer (5) via the adhesive layer (2).

  In the present invention, the lid material (10) may have a layer structure including a gas barrier layer (3), which is composed of a metal foil or a vapor deposition layer of an inorganic compound, mainly for improving the storage stability of the content. The example shown in FIG. 3 is an example including a gas barrier film layer (5) in which a vapor deposition layer of an inorganic compound is provided as a gas barrier layer (3) on the surface of a plastic film layer (4).

Although a metal foil such as aluminum is also effective as a gas barrier layer, it should be noted that when cooking in a microwave oven, sparks due to high frequency may occur.

  In the case of the gas barrier film layer (5), the plastic film used is a film made of a polymer resin composition, and like the base film (1), for example, polyolefin (polyethylene, polypropylene, etc.), polyester ( Polyethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate, etc.), polyamide (nylon-6, nylon-66, etc.), polyimide, etc. can be used and are appropriately selected according to the application. In particular, when polypropylene or polyethylene terephthalate is used as the plastic film substrate, it is more preferable in terms of film strength and cost.

  In the case of the gas barrier film layer (5), the gas barrier layer (3) can be composed of a vapor deposition layer and a coating layer of an inorganic compound. After the anchor coating is provided on the plastic film, the vapor deposition layer and the coating layer are sequentially provided.

  Urethane acrylate can be used for the anchor coat layer of the gas barrier film layer (5), for example. To form the anchor coat layer, a coating method in which a coating material obtained by dissolving a resin in a solvent is applied by a printing method such as gravure coating, or a coating method can be formed by using a generally known coating method.

  As a method for forming a vapor deposition layer, an inorganic compound such as SiO or AlO can be coated on a plastic film provided with an anchor coat layer by using a vacuum vapor deposition method to form an inorganic compound layer by a vacuum vapor deposition method. . Incidentally, the thickness of the vapor deposition layer is preferably 15 nm to 30 nm.

  As a method for forming the coating layer, an aqueous solution or water / alcohol containing at least one of a water-soluble polymer and (a) one or more alkoxides or hydrolysates thereof, or both (b) tin chloride. A coating agent having a mixed aqueous solution as a main component is applied on a film and dried by heating to form an inorganic compound layer by a coating method to form a coating layer. At this time, by adding a silane monomer to the coating agent, the adhesion with the anchor coat layer can be improved.

  The inorganic compound layer has a gas barrier property only by a coating film formed by a vacuum vapor deposition method, but a coating layer that is an inorganic compound layer formed by a coating method is formed on a vapor deposition layer that is an inorganic compound layer formed by a vacuum vapor deposition method to form a gas barrier layer. be able to.

  By combining these two layers, both reaction layers are formed at the interface between the inorganic compound layer formed by vacuum deposition and the inorganic compound layer formed by coating, or the inorganic compound layer formed by coating becomes an inorganic compound layer formed by vacuum deposition. A dense structure is formed by filling and reinforcing defects or fine holes such as pinholes, cracks, and grain boundaries that occur.

  Therefore, as the gas barrier film layer (5), higher gas barrier properties, moisture resistance, and water resistance are realized, and the gas barrier film layer (5) has flexibility to withstand deformation due to an external force, and thus is suitable as a lid member (10). it can.

  When SiO, for example, is used as the gas barrier layer (3), the coating is transparent, so that the contents can be seen from the outside of the lid member (10). These may be properly used depending on the application and the required quality.

Regarding the sealant layer (8), for example, the lid member (10) and the container body (20) are sealed by providing the sealant layer (8) on the surface of the lid member (10) on the container body (20) side. The cup-shaped container (30) can be sealed. At this time, the top seal layer (6) can be laminated via the adhesive resin layer (7), and it is effective in strengthening the adhesion between the layers.

  As the material of the sealant layer (8), a polyolefin resin is generally used among thermoplastic resins, and specifically, low density polyethylene resin (LDPE), medium density polyethylene resin (MDPE), linear low resin. Density polyethylene resin (LLDPE), ethylene-vinyl acetate copolymer (EVA), ethylene-α olefin copolymer, ethylene-methacrylic acid resin copolymer, and other ethylene-based resins, polyethylene and polybutene blend resins, Polypropylene resins such as homopolypropylene resin (PP), propylene-ethylene random copolymer, propylene-ethylene block copolymer, propylene-α-olefin copolymer and the like can be used. Further, from the viewpoint of sealing strength, it can be appropriately selected in consideration of the material of the container body (20) and the like.

  To form the sealant layer (8), a molten resin can be formed into a film using an extruder or the like to form a layer on the surface of the lid member (10) on the container body side. As described above, this can be laminated via the adhesive resin layer (7), which is preferable from the viewpoint of strengthening the adhesion between the layers.

  Alternatively, it is possible to form the sealant layer (8) on the surface of the laminate that constitutes the lid material (10) by laminating materials that have been formed into a film in advance by laminating.

  The container body (20) may also include a gas barrier layer in the layer structure or be provided on the surface. Similar to the case of the lid member (10), this aims at, for example, improving the storability of the contents and preventing alteration of the contents due to the environment.

  For example, it is effective to provide an ethylene / vinyl alcohol copolymer resin as a gas barrier layer in a layer forming the container body (20), and a resin material having a gas barrier property is provided on the surface of the container body (20). It may be coated to form a gas barrier layer.
