- Patent Document 2 Japanese Patent Laid-Open No. 2002_531394
- the microcapsules shown in Patent Document 1 and Patent Document 2 generally increase the density of the microcapsules, and when the density is increased, the interval between the microcapsules becomes extremely narrow and the arrangement of the microcapsules is increased.
- the densest arrangement pattern will be adopted as the pattern.
- the present invention has been made in view of the above problems, and a microcapsule sheet that can be used for pharmaceutical use without requiring the work of separating and collecting the microcapsules from the substrate.
- a microcapsule sheet that can be used for pharmaceutical use without requiring the work of separating and collecting the microcapsules from the substrate.
- microcapsule sheet according to claim 1 is formed by dividing micro force capsules into a plurality of regions on a substrate made of an edible film.
- microcapsules are preferably formed by surrounding a core layer with a first shell film and a second shell film! /.
- the plurality of regions are a plurality of regions that are spaced apart from each other!
- Each region is preferably a region in which a predetermined number of microcapsules are arranged. ,.
- microcapsules can be arranged at a high arrangement density in each region, so that the density of the microcapsules can be increased, and the force and the regions can be easily separated. Therefore, it is possible to facilitate the arrangement of the microcapsules with a predetermined amount smaller than the entire sheet as a unit.
- microcapsules can be ingested as they are without being separated from the base material, and operations such as separation, collection, and packaging of the microcapsules can be made unnecessary. Work can be greatly simplified. Of course, there is no decrease in yield in operations such as separation, collection, and packaging, and manufacturing costs can be reduced.
- the sheets may be hardened into a shape that is easy to drink.
- the sheet can be wound and packed into a capsule, and the microcapsule can be handled in units of sheets without directly handling, thereby reducing the manufacturing cost.
- the plurality of regions are a plurality of regions spaced from each other, and each region is a region in which a predetermined number of microcapsules are arranged, a desired unit can be simply set as a unit.
- An amount of microcapsules can be taken. For example, if divided into units such as the amount of medicine determined per body weight and the amount of intake at one time, the effect of further increasing the convenience will be obtained and the best mode for carrying out the invention
- FIG. 1 is a schematic view showing an example of an apparatus for producing the microcapsule sheet of the present invention.
- This apparatus supports an XY stage 2 that supports a substrate 1 made of an edible film and moves it in a two-dimensional manner, a droplet including the first shell material from above the substrate 1, and a core material.
- the liquid droplets including the liquid droplets and the liquid droplets including the second shell material are respectively supplied and adhered to the surface of the base material 1.
- the nozzle device 3 having the three liquid droplet nozzles and the first liquid droplets are dried and dried.
- a drying apparatus 4 for forming a shell film and a second shell film.
- the droplet supply nozzle is used in an inkjet printer! /, For example, a piezo head that discharges droplets by utilizing the property that piezoelectric ceramics are distorted, and thermal energy. Since the droplets are discharged by the thermal ink jet head that discharges the droplets, the discharge amount can be controlled with high accuracy.
- the nozzle device 3 has three droplet supply nozzles, so that the nozzle device 3 is sequentially arranged at the same position.
- the three droplet supply nozzles In order to operate the three droplet supply nozzles, it is configured to be reciprocated according to the arrangement of the three droplet supply nozzles!
- an infrared heater can be employed as the drying device 4 for example.
- the substrate 1 is moved to a predetermined position by the XY stage 2, and one of the three droplet supply nozzles of the nozzle device 3 is driven, so that the droplet including the first shell material is transferred to the substrate. Adhere to 1. In this state, the droplet is almost hemispherical (see (A) in Fig. 2).
- the surface is first dried to form a film, and then the drying operation is continued to evaporate the internal solvent and the like.
- the resulting film is made concave (see (B) in Fig. 2).
- the film may simply be flattened.
- the other one of the three droplet supply nozzles of the nozzle device 3 is driven to deposit a droplet including the second shell material so as to cover the core layer.
- the drying device 4 is operated, the droplets containing the second shell material are dried, and the second shell layer is formed. ⁇ See (D) in Figure 2 ⁇ .
- the microcapsules 5 can be arranged in a predetermined pattern only in a desired region on the substrate 1. Specifically, for example, as shown in FIG. 3, the base material 1 made of an edible film is virtually divided into a plurality of regions la, and a partitioning part lb is set between the regions la. In addition, the microcapsules 5 can be arranged only in each region la. It should be noted that, for example, the setting of the virtual division of the areas la and the division part lb between the areas la is performed by, for example, a controller (not shown) for controlling the XY stage 2 with the area la.
- the total amount of droplets including the core material per region la which is preferably determined based on the number of microcapsules 5 to be arranged, can be set to a predetermined amount.
- the arrangement density of the microcapsules 5 in each region la in which the arrangement pattern of the microcapsules 5 in each region la is preferably the most dense arrangement, can be increased.
- the sorting portion lb be set to a width that can be easily cut by a scissors or the like.
- microcapsule sheet produced as described above examples include pharmaceuticals.
- the microcapsule sheet is used as a medicine
- a edible film, a polysaccharide film, or a protein film is used as the edible film
- an enteric polymer film for example, is used as the first shell material.
- insulin, erythropoietin, physiologically active protein, peptide, or the like can be employed as the core material, and a gel-forming material may be added to the core material as necessary.
- a gel-forming material may be added to the core material as necessary.
- the second shell material for example, water-insoluble polymers and waxes are used with a force S.
- a water-repellent pattern is formed on the microcapsule-formed surface.
- a material that forms a turn therefore, a material liquid for preventing the spread of wetness and forming the first shell material in the water-repellent pattern can be present.
- the microcapsule 5 can be miniaturized.
- the surface other than the microcapsule formation surface (the hatched portion in FIG. 4) is subjected to water repellent treatment to prevent the microcapsule formation surface from spreading out.
- the microcapsule 5 having a small diameter can be formed.
- a water-repellent frame (ring shape, lattice shape, etc.) (the hatched portion in FIGS. 5 and 6) is provided around the microcapsule forming surface.
- the microcapsule 5 can be reduced in size by preventing wetting and spreading of the microcapsule forming surface.
- a substrate 1 made of an edible film in which a recess is formed by embossing on the microcapsule forming surface it is preferable to use a substrate 1 made of an edible film in which a recess is formed by embossing on the microcapsule forming surface.
- a printing method using a squeegee The material for forming the first shell material can be applied to the recess.
- the present invention provides a microcapsule sheet that can increase the density of the microcapsules 5 and can facilitate the force and positioning of the microcapsules in units of a predetermined amount of microcapsules that are smaller than the entire sheet. provide.
