The lid 10 can be peeled off by picking up one end and pulling it toward the other end, and the peeling portion rises when peeled off to take out the contents from the contents outlet 2 of the package 1. The re-adhesive coated pressure-sensitive adhesive layer 16 is formed such that the portion 18 is formed and the peeled-off portion covers the content outlet 2 of the package 1.
Is formed so as to be re-adherable.

The covering sheet 12 includes a covering substrate 20 made of paper, a synthetic resin sheet or the like having a substantially rectangular shape in a plane, and the covering substrate 2
The first adhesive layer 22 is formed on the back surface of the “0”. The cover sheet 12 is formed at one end (the left end in the illustrated example) of the cover sheet 12, and is used to pick up from one end and pull toward the other end, and a knob 28. On the opposite side, a fixed portion 26 which is always fixed to the package 1 is formed, and a peeling portion 24 which is separated by the knob 28 to form the rising portion 18 and a fixed portion 26 which is always fixed.
, That is, at the boundary with the strip-shaped constantly fixed portion 26 formed on the opposite side (the right end in the illustrated example) to the knob 28.

The coated base material 2 is formed so that the rising portion 18 formed at the peeling portion 24 to be peeled is reliably raised.
A rising auxiliary sheet 30 of the same type as the covering base material 20 is adhered to the back surface of the base material 0 with the first adhesive layer 22. That is,
The rising auxiliary sheet 30 is adhered to the coating substrate 20 with the first adhesive layer 22 formed on the back surface of the coating substrate 20, and the rising auxiliary sheet 30 separates the coating substrate 20 at the rising portion 18 portion. It is divided into a peeling portion 32 that is peeled off from the package 1 together with the portion 24, and a constant fixing portion 34 that is fixed to the package 1 together with the constant fixing portion 26 of the coating base material 20.

A perforation and / or cut portion 36 is formed at the boundary between the peeled-off portion 32 and the fixed portion 34 which is fixed. That is, the covering sheet 1
In the case of No. 2, a fixed portion 26 is formed at one end of the covering sheet 12 (the left end in the illustrated example) on the side opposite to the knob 28, and the peeling portion 24 and the fixed portion 26 are fixed to each other. In other words, a perforation 36 is formed at the boundary of the above, that is, at the boundary with the strip-shaped constantly fixed portion 26 formed on the opposite side (the right end in the illustrated example) to the knob 28.

The rising auxiliary sheet 30 includes a peeling part 32 corresponding to the rising part 18 corresponding to the peeling part 24 of the coating base material 20 and a constant fixing part 34 formed through a perforation 36. The peeling portion 24 of the base material 20 and the peeling portion 32 of the rising auxiliary sheet 30 are formed to have substantially the same shape, and the constantly fixed portion 26 of the coating base material 20 and the constantly fixed portion 34 of the rising auxiliary sheet 30 are formed to have substantially the same shape. Is formed. The perforation 36 is not formed on the coating base material 20, and the peeling portion 32 and the fixed portion 34 are merely separated by the perforation 36 formed on the rising auxiliary sheet 30. A second adhesive layer 38 is formed on the back surface of the rising auxiliary sheet 30.
Thereby, the reinforcing sheet 14 is stuck.

When the cover sheet 12 is peeled off from the package 1, the reinforcing sheet 14 remains on the surface of the package 1 and is always fixed to the surface of the package 1 in a state of being fixed to the package 1. When the coated base material 20 is peeled off, it is divided into a peeled portion 52 which is a part to be peeled off.

The reinforcing sheet 14 is integrated with the peeling portion 32 of the rising auxiliary sheet 30 in a frame of a substantially fixed dough-shaped fixed portion 50 having a substantially square shape and an elliptical outer shape.
A peeled portion 52 that is further peeled is formed. Reinforcement sheet 1
4 has almost the same outer shape as the covering sheet 12,
The fixed portion 50 and the peeling portion 52 are divided by a cut 54 formed in the width direction, and the re-adhesive coating pressure-sensitive adhesive layer 16 is formed on the back surface of the peeling portion 50. Although the pressure-sensitive adhesive layer 56 is formed on the back surface of the fixed portion 50, the pressure-sensitive adhesive layer 56 is not necessarily a re-adhesive type.

If the covering sheet 12 is peeled off from the package 1 with the knob 28, the peeling portion 32 of the rising auxiliary sheet 30 and the peeling portion 52 of the reinforcing sheet 14 rise up with the integrated part, and the contents are taken out.
