摘要： The present invention makes it possible to provide a cell culture membrane capable of easily decomposing after allowing cell layers to be formed on both sides of the cell culture membrane. A cell culture membrane having a cell culture region at both surfaces thereof, the cell culture membrane containing methyl cellulose having a weight average molecular weight of from 20000 to 190000 as a main component, or containing methyl cellulose having a weight average molecular weight of from 190000 to 400000 as a main component, and further containing a dissolution temperature regulator. The dissolution temperature regulator is preferably at least one of sodium styrenesulfonate, sodium iodide, or sodium toluenesulfonate. A poorly soluble material is preferably added to the cell culture membrane.

摘要： The present invention ensures pressure-resistant strength and dropping strength while ensuring a prescribed filling amount of a content. Provided is a bottomed cylindrical aluminum alloy can body comprising a can bottom 11 and a can barrel 12. The can bottom has a dome part 111 provided at a central part thereof, and an annular protruding part 112 provided at an outer peripheral edge of the dome part. The annular protruding part is provided continuous with the dome part, and includes a recess part 112A having a curved surface protruding outward in a radial direction of the can barrel, a grounding part 112B supporting the can body, and an inner peripheral wall part 112C ranging from the grounding part to the recess part. The outer diameter of the can barrel is in the range of 50 mm or more and 59 mm or less in diameter, and the height from the grounding part to the upper end of the can body is in the range of 120 mm or more and 190 mm or less. In a vertical cross-sectional view including a can axis, the depth of the recess is 0.5 mm or more and 0.8 mm or less, and a grounding diameter ϕ is 44.0 mm or more and 47.0 mm or less.

摘要： The present invention relates to a seamless can and a coated metal sheet that can be used to form the seamless can. The seamless can includes an inner surface coating film at least on a can inner surface side. The inner surface coating film has an excellent coating film covering property and corrosion resistance. When the inner surface coating film contains a polyester resin and a total amount of polyvalent carboxylic acid components in the polyester resin is 100 mol%, a content of an aromatic dicarboxylic acid is 70 mol% or more. The inner surface coating film has a gel fraction (A) represented by Formula below of less than 90%: Gel fraction (A) = (W2a/W1a) × 100 (%) ... (1a),
where W1a represents a mass of the inner surface coating film isolated from a coated metal substrate cut out from the seamless can, and W2a represents a mass of the isolated inner surface coating film after being immersed in MEK at ordinary temperature for 60 minutes and then taken out and dried.-

摘要： In the present invention, a method for producing a drawn/ironed can includes drawing and ironing a coated metal sheet to obtain a drawn/ironed can, the coated metal sheet having an inner surface coating film at least on a surface to be a can inner surface, and a glass transition temperature (Tg) of a polyester resin contained in the inner surface coating film is 55°C or higher, an ironing rate in the drawing and ironing is 40% or greater, and a processing speed during ironing in the drawing and ironing is 2000 mm/sec or higher. Thus, even in a case where a coated metal sheet having a coating film that has excellent flavor sorption resistance and contains a polyester resin having a high glass transition temperature as a main component is used, it is possible to suppress occurrence of a coating film defect during molding and occurrence of coating film peeling due to heat treatment.

摘要： A master batch includes a matrix resin containing a propylene-based resin and a non-volatile liquid with a boiling point of 200°C or higher dispersed in the matrix resin. Temperature conditions represented by the relationships below are satisfied:
Tm
Tc ≥ 97°C, and
Tm - Tc
where Tc is a crystallization temperature indicated, in DSC measurement, as a peak top temperature of an exothermic peak observed on a highest temperature side when cooled to -50°C at a temperature lowering speed of 10°C/min after heat treatment for 5 minutes at 200°C and Tm is a melting point indicated, in the DSC measurement, as a peak top temperature of a melting peak observed on a highest temperature side when heated from -50°C to 200°C at a temperature rising speed of 10°C/min after being cooled.-

摘要： Provided is a culture vessel for adherent cells that has a large culture portion surface area and ensures easily dissociating and recovering cells without consuming a medium or a dissociation solution more than necessary. The bag-shaped adherent cell culture vessel made of flexible packaging material includes a vessel body portion (1) having a first vessel wall (11) and a second vessel wall (12) and one or more injecting/ejecting ports (2). The vessel body portion (1) has an intermediate culture wall (13) between the first vessel wall (11) and the second vessel wall (12). A culture chamber is disposed in each of between the first vessel wall (11) and the intermediate culture wall (13) and between the second vessel wall (12) and the intermediate culture wall (13), and a flow passage (14) communicating between the respective culture chambers is disposed.
