In addition to the present invention, the usability of the present invention may be further increased by using a technique disclosed in japanese patent No. 5580496, which has been filed by the applicant of the present invention, in combination with a plate body, a stacked body, and a storage body, each of which is provided with a sheet material that is stuck to a three-dimensional shape of a human body, and at least one protruding portion is provided at an outlet of the plate body.

In addition to the present invention, the usability of the mask sheet may be further increased by a technique of folding a flat body provided with the mask sheet extending to both the left and right ends and hooked to both the left and right ears in two left and right directions around the longitudinal direction of the bridge of the nose as an axis, folding the forehead portion and the lower portion back and forth along an arbitrary line intersecting the longitudinal direction, and enclosing the package, as disclosed in japanese patent No. 5676804 already filed by the applicant of the present invention.

Examples

Fig. 2 shows an embodiment of the package body of the present invention having a plate body and an opening/closing cover, wherein the opening/closing cover is held by a holding portion and peeled to a peeling stop portion to prevent the peeling of the opening/closing cover from returning, a return prevention piece is operated by a finger or the like to a position closer to an opening portion than the peeling stop portion, a tip end portion of the return prevention piece is fitted to at least one groove portion provided in the plate body to fix the opening/closing cover at a position near an end point of the opening portion, the opening/closing cover is held to prevent the return to the opening portion side to bring the opening/closing cover into a standing state, the opening portion is provided in a top surface, and sheets of a stacked body in which the package bag is sealed are easily held and smoothly taken out one by one. At the time of or after the removal, the use method described in the article may be followed.

Instead of the front end portion of the return prevention piece, the front end portion of the grip portion may be fitted to at least one groove portion provided in the plate body, so that the opening/closing cover is fixed at a position near the end point of the opening portion, and the opening portion is opened, whereby the sheets of the stacked body sealed in the packaging bag can be easily gripped and smoothly taken out one by one.

Alternatively, in the case where the adhesive portion is not provided in the vicinity of the groove portion provided in the plate body, the opening portion may be provided by press-fitting the tip portion of the return prevention piece into the groove portion and fitting the same, and then press-fitting the tip portion further deeply, thereby fixing the return prevention piece to the groove portion of the plate body.

In another embodiment in which an opening for taking out the sheet is provided, the distal end of the return preventing portion or the distal end of the grip portion may be locked and fixed to the stepped portion.

Further, the front end portion or the grip portion of the adhesive-free return prevention sheet is deeply pressed into the vicinity of at least one groove portion or the vicinity of the step portion of the adhesive-free return prevention sheet and the bag body, thereby smoothly fixing the adhesive-free return prevention sheet.
