FIG. 3 is a perspective view showing the container 3 in which the lid member 1 of the first embodiment is thermally bonded to the container body 2. FIG. 4 is a perspective view showing a state in which the lid member 1 is torn in the container 3 according to the present invention having the lid member 1 of the first embodiment, and a swing outlet 22 is formed. In FIG. FIG. 2 shows a state in which a laminated body is linearly cut along a planned cut line from a base portion and a swing outlet is formed in a container. The lid 1 and the container 3 according to the first embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1, the lid 1 according to the present invention includes a laminate 10 in which a paper layer 11, a base material 12 made of a uniaxially stretched film, an aluminum foil layer 13, and a thermal adhesive resin layer 14 are laminated.

  As shown in FIG. 2, the lid member 1 has a substantially circular shape, and has an opening tab 15 that protrudes outward from the periphery of the container body on one peripheral edge, and an opening tab 15 that faces the other peripheral edge. An opening tab 17 is provided at a position to be opened. The unsealing tab 15 has a shape having both end protruding portions 15b and 15b protruding from the base portions 15a and 15a toward the outside from the periphery of the container body. Further, the opening tab 15 is provided with a straight cut line 16 connecting the base portions 15a and 15a. Furthermore, the direction of the linear cut planned line 16 is the same as the stretching direction (arrow in FIG. 2) of the uniaxially stretched film of the substrate 12 (see FIG. 1) made of the uniaxially stretched film. By adopting such a configuration, it is possible to tear the lid 1 made of the laminate 10 linearly along the planned cutting line 16 from the one base portion 15a of the opening tab 15 to the other base portion 15a. It will be. In addition, the structure of the tab 15 for opening is not limited to both end protrusion parts 15b and 15b, Although a protrusion part can also be made into only one side, the direction made into both ends is from either of both end protrusion parts 15b and 15b.

  As shown in FIGS. 3 and 4, the lid member 1 has a circular opening 20 on the upper side and a flange 21 of the container body 2 provided with a flange 21 on the periphery of the opening 20. The surfaces are brought into contact with each other and thermally bonded, and the opening 20 is covered and sealed to form the container 3 of the present invention. In addition, although the container main body 2 illustrated the cup shape of the inverted truncated cone which has an opening part upwards, a square shape may be sufficient. In the case of a rectangular container body, the lid material to be used is approximately the same size as the peripheral edge of the container main body, an opening tab that protrudes outward from the peripheral edge of the container main body is provided at the corner, and a swing outlet is formed at the corner. What is necessary is just composition. However, it is important that the stretching direction of the uniaxially stretched film and the direction of the straight cut-out line provided from the base portion of the opening tab are the same direction.

  One feature of the laminate 10 constituting the lid 1 of the present invention is that it includes a base material made of a uniaxially stretched film stretched in one direction. Moreover, the structure which does not contain the film biaxially stretched in the laminated body 10 is more preferable, and a linear tear along the extending | stretching direction of a uniaxially stretched film becomes more excellent than the opening tab. Furthermore, it is preferable that the base portion 15a of the opening tab 15 protrudes inward of the lid member 1 and has a curved shape or a V shape having a planar view radius with the portion as an inflection point or a bending point. By doing so, it is possible to tear the lid 1 straight from the base 15a of the unsealing tab 15 along the planned cut line, and there is no notch as in the conventional case. The lid member 1 can be prevented from being torn from the base portion 15a by an external force. Furthermore, since no notch is provided, when the container body 2 and the lid material 1 are thermally bonded, there is a wide allowable range in which the positional deviation between the container body 2 and the lid material 1 is allowed, and the work for thermal bonding is improved. To do. In addition, it is possible to reduce misalignment and improve the yield rate. The root portion refers to an inflection point between the periphery of the lid member and the periphery of the opening tab or the vicinity including the inflection point. However, when the base portion is bent without being rounded, it is a bending point.

The thickness is usually 6 to 50 μm, more preferably 12 to 40 μm. In addition, the order of lamination of the base material 12 made of a uniaxially stretched film in the laminate 10 is not particularly limited as long as it is other than the innermost surface (the surface facing the container body). The paper layer 11 can be used high-quality paper having a basis weight ^{40g / m 2 ~100g / m 2} , kraft paper, coated paper or the like. The aluminum foil layer 13 is made of a soft, hard, semi-hard or alloy foil having a thickness of 5 to 20 μm. The thermal adhesive resin layer 14 is a resin having thermal adhesiveness with the container body 2, for example, low density polyethylene, medium density polyethylene, high density polyethylene, linear (linear) low density polyethylene, polypropylene, ethylene-α olefin. Known thermal adhesive resins such as copolymers, ethylene-propylene copolymers, ethylene-vinyl acetate copolymers, ionomer resins, ethylene-acrylic acid acid copolymers, ethylene-acrylic acid ester copolymers, and ethylene / Vinyl acetate copolymer, or a container body such as a resin in which polystyrene or polybuden is mixed with the above resin can be used and easily peelable resin, and the type of resin of the container body and the required adhesion between the container body It is selected as appropriate in consideration of strength. As a method for laminating each layer, a known laminating method such as a dry lamination method or a sandwich lamination method may be used, and the thermal adhesive resin layer 14 may be laminated by an extrusion lamination method.

  Next, a typical configuration example of the laminate 10 is shown as <paper layer 11 / uniaxially stretched film 12 / aluminum foil layer 13 / thermoadhesive resin layer 14>, <paper layer 11 / aluminum foil layer 13 / uniaxially stretched film. 12 / thermal adhesive resin layer 14>, <uniaxially stretched film 12 / paper layer 11 / aluminum foil layer 13 / thermal adhesive resin layer 14>, and the like. The paper layer 11 or the uniaxially stretched film 12 is usually provided with a printing layer.
