Description

  The present invention relates to an opening moving structure in a membrane member, and more particularly to an opening moving structure in a membrane member in which an opening is formed in a membrane member that partitions a space and the formed opening is slid along the membrane member.

  As a member for partitioning the space easily, for example, a film member (curtain member) made of a flexible synthetic resin sheet material is often used. For example, when removing or handling harmful substances such as asbestos and dioxin, a film member that partitions the removal work space from the outside is used as a shielding film for preventing the diffusion of these harmful substances.

  Also, for example, when removing or handling harmful substances such as asbestos and dioxins, the worker does not enter the removal work space shielded by the shielding film, and is opposite to the removal work space sandwiching the shielding film. The so-called glove bag system that allows workers to work in the removal work space from the entrance space side where the work can enter through the work opening formed in the shielding film and the work bag-like film attached thereto Has been proposed (see, for example, Non-Patent Document 1).

  According to such a work method using the glove bag method, not only the removal work of harmful substances in the removal work space but also the other sterile work space such as a sterile room shielded by a membrane member. Without entering the room, various operations can be performed from the entrance space side on the opposite side to the aseptic room.
