The invention relates to a battery steel belt, a battery steel shell using the steel belt and a manufacturing method for the steel shell. The battery steel belt is characterized in that nickel electroplated layers are separately formed on the surfaces, wherein the thickness of the nickel plated layer on the inner surface is greater than that of the nickel plated layer on the outer surface; the plated layers on the surfaces of the steel belt are subjected to thermal treatment to interpenetrate with matrix to form Fe-Ni alloy layers; and the Fe-Ni alloy layers formed by thermal treatment are compact in structure, are good in corrosion resistance; bonding force between the Fe-Ni alloy layers and Fe matrix is much greater than that between regular electroplated layers and the Fe matrix, so that the possibility of generating cracks during steel shell punching is reduced, and conditions can be provided for forming post-electroplated Ni layers with good bonding force on surfaces. After being subjected to nickel pre-plating and nickel post-plating, the steel shell has the characteristic that the nickel layer on the inner surface is thick, so that power storage of a battery is improved, compactness and corrosion resistance of the battery are much better than those of a battery with a single electroplated nickel layer, and therefore, the battery leakage problem caused by dissolution of steel shell matrix iron during long-term storage of the battery is solved.

A slow-release orally dissolving capsule has been described, which releases medicaments in the mouth cavity up to 1 hour. The medicaments may have a therapeutic effect in the mouth cavity and a portion of the drug is delivered to stomach.

Also, large capsules such as size “000” can be administered allowing delivery of large amounts (800 to 1600 mg) of medicament. The medicament can be absorbed through mouth cavity to blood stream bypassing hepatic first pass metabolism. In some instances, a drug(s) is incorporated in the capsule shell matrix and no drug composition is filled inside the capsule shell core.
