した。(Prior Art) As shown in FIG. 8, this type of container lid has a ring 3 that fixes the lid 1 to the rim of the container body and a foil 4 made of aluminum or the like that covers the inner hole of the ring 3. It is known that the foil 4 is formed with a tension aperture piece 5 for tearing the foil 4 to make an opening. Then, the tension opening piece 5 is adhered to the entire surface of the foil 4, and a partial opening part 5a for partially breaking and opening the foil 4 is attached to the partial opening part 5a via a bendable connecting part 10. The applicant has already proposed a method in which a fully open portion 5b is formed to break open the entire continuous foil 4.

ある。 When such a structure is adopted, the partially open portion 5a has a tip portion 5 in order to open by tension.
c is not bonded to the foil 4 and is a free end that can be grasped, and by pulling up this tip 5c, the partially open portion after the starting end 6 of the bonded portion between the partially open portion 5a and the foil 4 is opened. The foil 4 below 5a is broken to open it. Then, if necessary, following the opening by the partial open part 5a, the foil 4 under the full open part 5b is broken open. At this time, if the foil 4 is relatively thick, the partially open portion 5
When trying to break the foil 4 from the starting end 6 by pulling up the foil 4, there is an inconvenience that the adhesive part peels off without the foil 4 being broken at the starting end 6 and the periphery of the partially open part 5a, so this is avoided. Therefore, if the foil 4 is made thinner, there is an inconvenience that it may break inadvertently.

４の全面を覆うようにした。 In the figure, reference numeral 1 denotes a lid having a structure similar to that previously proposed by the applicant shown in Figure 8, and more specifically, it is made of a metal material, such as stain-free steel, that is fixed to the rim of the container body 2. It is formed from the formed ring 3, a metal foil 4a made of aluminum or the like that covers the inner hole of the ring 3, and a foil 4 made of a thermoplastic resin coating 4b that covers one surface thereof. The upper surface of the foil 4 has a foil 4
A tensile aperture piece 5 made of a thermoplastic resin having a tear strength greater than the tear strength of is adhered by fusion. The tension opening piece 5 has an annular knob 7 that extends integrally with the upper surface of the foil 4 from the starting end 6 of the adhesive part of the opening piece 5 located on the center side of the lid body, and an annular knob 7 that extends integrally with the upper surface of the foil 4. A knob piece 9 is connected to the hole through a raised piece 8, and a partial open part 5a is connected to the opposite side of the knob 7 and extends in the radial direction to the inner circumference of the ring 3. It is formed of a fully open part 5b connected to a partially open part 5a via a bendable connecting part 10, and a small gap 11 and a part that can be easily separated by bridging the small gap 11 are formed on the periphery of the opening piece 5. adjacent contour member 1 via bridge 12
3 was provided so that the entire surface of the foil 4 was covered by the contour member 13 and the opening piece 5.

した。 The above structure is the same as that of the lid body shown in FIG. 8, but in the present invention, as shown in FIGS. Established. The opening piece 14 has a sharp tip portion 15 made of hard synthetic resin or the like having greater rigidity than the opening piece 5.
are stacked so as to face the vicinity of the starting end 6 of the adhesive part with the foil 14 of the partially open part 5a, and a rivet 17 formed integrally with the partially open part 5a is inserted and heated through the hole 16 formed in the intermediate part. The ends were crushed and tied. The rear end 18 of the opening piece 14 has an outwardly curved shape to facilitate gripping.

る。 With this structure, when opening the lid 1, the rear end 18 of the opening piece 14 is opened as shown in the third figure.
When it is grasped and lifted with the fingertips, its sharp tip 15 tilts and breaks through the vicinity of the starting end 6 of the adhesive part of the partially open part 5a to form an initial break part. Next, remove the knob 9 of the partial open portion 5a.
At the same time, when the knob 7 is lifted and pulled up in the longitudinal direction of the partial open section 5a, the foil 4 under the partial open section 5a is easily broken open. If necessary, the foil 4 below the fully open portion 5b is further cut open at the small gap 11 and the inner circumferential position of the ring 3.

a does not have a configuration corresponding to the knob 7 as in the above embodiment, and the partial open portion 5a is not provided with the foil 4.
It is completely fused to. In this case, the starting end 6 of the adhesive part of the partially open part 5a coincides with the starting end of the partially open part 5a. Therefore, the sharp tip 15 of the opening piece 14 is located on the starting end 6 side of the partially open portion 5a. The partially open portion 5a is connected to the fully open portion 5b at a connecting portion 10.

とした簡易開口容器蓋を提供できる効果がある。(Effect of the invention) According to the invention, the inner hole of the ring forming the lid body is covered with foil, and a partial opening portion and a partial opening are formed on the foil as means for breaking the foil at the time of opening. In the case where a tension aperture piece with an open part connected to the foil is glued, the sharp tip part faces near the starting end of the bonded part between the partially open part and the foil, and the middle part is fixed to the partially open part. Since the opening piece is attached, and when the foil is grasped at the rear end and pulled up, the sharp tip tilts and breaks the foil, the opening piece makes it extremely easy to cause initial breakage when opening the foil. Therefore, even if the film thickness of the foil is relatively thick, or even if the opening area is relatively small, such as a partially open part, the opening operation can be performed reliably and extremely easily. This has the effect of providing an easy-to-open container lid.
