2 is a longitudinal sectional view of a drum having a heated platen moved downward to contact the seal.

Claims (10)

A sealed container for thermoplastic storage, having a side and a bottom surface that can interact with the platen to empty the thermoplastic when the container is placed at the point of use, wherein the top layer is filled with exposed moisture or air-sensitive thermoplastic. Exposure of the moisture or air sensitive material to the moisture or air sensitive material in the container to protect the exposed layer and to seal the material from moisture and air during storage and transportation of the container to the container. A sealed container for thermoplastic storage, characterized in that it constitutes a seal which can be peeled from the layer and has a moisture and air low transfer rate in contact with the side of the container and extended over the exposed layer. The sealed container of claim 1, wherein the cover is a thermoplastic layer that is solid at room temperature and has a sufficient adhesive force to be peeled from the upper layer of the moisture or air sensitive material. 3. The sealed container of claim 2, wherein the thermoplastic material forming the cover is a styrene-butadiene interpolymer or a styrene-isoprene interpolymer. The sealed container of claim 1, wherein the cover is a thermostable polymer layer having sufficient adhesion to be peeled off from an upper layer of the moisture or air sensitive material. 5. The sealed container of claim 4, wherein the thermostable polymer forming the cover is polyurethane, polyurea or polysiloxane. 6. The viscosity as claimed in claim 1, 2, 3, 4 or 5, wherein the moisture or air sensitive material must be heated by a heated platen in order to be emptied. Sealed container for thermoplastic storage, characterized in that there is. Thermoplastic material according to claim 1, 2, 3, 4 or 5, characterized in that the moisture or air sensitive material becomes such viscosity at room temperature which can be emptied without the application of heat. Sealed container for storage. 6. A sealed container for thermoplastic storage according to claim 1, 2, 3, 4 or 5, comprising a separating sheet between the moisture or air sensitive material and the cover. . 10. The sealed container of claim 8, wherein the separation sheet has a discharge characteristic on at least one side. 10. The method of claim 9 wherein the separation sheet is polytetrafluoroethylene, polyethylene, aluminumized polyethylene, polyester, siliconized polyester, aluminum foil, polytetrafluoroethylene coated with aluminum foil, kraft paper, kraft paper coated silicone And or polytetrafluoroethylene coated with raft paper. ※ Note: The disclosure is based on the initial application.
