Embodiment 1
[0015] figure 1 is a front appearance view showing the volatile drug sustained release member 17 of this embodiment, Figure 2A and Figure 2B The cross-sectional structure of the volatile drug sustained-release member 17 is shown. In order to clearly explain the configuration of each component, Figure 2B The thicknesses of the respective constituent parts are shown as more than actual values for emphasis.
[0016] The internal dimensions of the container 1 are 50 x 140 x 10 mm and it is made by vacuum molding a coextruded sheet with a thickness of 0.8 mm. The coextruded sheet was composed of cast polypropylene (CPP, thickness 370 μm) / ethylene-vinyl alcohol copolymer (EVOH, thickness 60 μm) / CPP (thickness 370 μm). The volatile agent 2 is a small flake obtained by solidifying the chemical substance allyl isothiocyanate with cellulose ether. When making the flakes, add 7.5 g of cellulose ether powder (Nissin Chemical, エトセル STD-100, weight average molecular weight: 180,00...
Embodiment 2
[0027] In Example 2, 15 g of allyl isothiocyanate and cellulose ether were mixed in a weight ratio of 4:1, increased to a viscosity of 100,000 CPS, and then transferred to a tank of calcium carbonate powder to form a lump. Then, the dough-forming mixture was filled into the pillow package 3 of the same laminated film as in Example 1. For the laminated film of OPP 30 μm and LDPE 70 μm, the LDPE side was heat-sealed to form a pillow package to obtain a pillow package 3 of 40×125×about 4 mm. The laminated film has a first gas permeable film as a primary control film. The configuration of the container 1 for containing the pillow package 3 as the volatile drug sustained-release member 17 and the cover 40 including the moisture-sensitive film 4 is substantially the same as in Example 1, and the pillow package 3 is fixed on the pillow package 3 by heat-melting LDPE. The inner surface bottom of the container. The size of the space provided between the primary control membrane and t...
Embodiment 3
[0029] In Example 3, 15 g of allyl isothiocyanate and cellulose ether were mixed at a weight ratio of 8:1, increased to a viscosity of 20,000 CPS, and then transferred to a tank of aluminum hydroxide powder to form a lump. Then, the dough-forming mixture was filled into the pillow package 3 of the same laminated film as in Example 1. The pillow packaging body 3 of the laminated film forms a primary control film. For the laminated film (the first air-permeable film) of OPP (thickness 30 μm) and LDPE (thickness 70 μm), the LDPE side is heat-sealed to form a pillow package, and a 40×125 ×Pillow package of about 4mm. The configuration of the container 1 for containing the pillow package 3 as the volatile drug sustained-release member 17 and the cover (secondary control film) 40 containing the humidity-sensitive film 4 is substantially the same as that of Example 1, and the The pillow package 3 is fixed on the bottom of the inner surface of the container 1 . The size of the space...
