An embodiment of the present invention provides a coating method, a coating bar head and a coating apparatus which enables coating in which changes in coating film thickness is less likely to occur, even when performing meniscus coating at a high speed. This coating method is a coating method including: supplying a coating liquid between a coating bar head and a substrate to form a meniscus; and moving the substrate, wherein a cross section of the coating surface of the bar head in the direction of coating, is a convex curve, and has bending points at both ends of the curve.

A dispenser (10) for dispensing a flowable material M has a container (12) having an outer wall (20) and membrane (14) collectively defining a first chamber (22) configured to contain the flowable material M. The membrane (14) has a thickness and a weld seam (40) wherein the weld seam (40) has a thickness less than the thickness of the membrane (14). A fracturing mechanism (16) is operably connected to the container (12). The fracturing mechanism (16) has an extending member (64) projecting from the outer wall (20) of the container (12). The extending member (64) has a projection (66) positioned proximate the membrane (14), wherein in response to deflection of the extending member (64), the projection (66) deflects the outer wall (20) proximate the membrane (14) wherein the weld seam (40) fractures creating an opening (41) through the membrane (14) configured to allow the flowable material M to pass therethrough and from the dispenser (10).

The embodiment provides a coating process capable of simply and inexpensively producing devices having strip-shaped cells, and a coating apparatus usable for the process. The process comprises: (a) placing a bar coating head almost parallel to the substrate, (b) placing plural coating nozzles for supplying coating solution to meniscus-forming parts, so that the center between each adjacent two of the coating nozzles may correspond to the separation area between each adjacent two of the strip-shaped cell bases, and (c) moving the substrate or the bar coating head while the coating solution is being supplied from the nozzles, to form the coating films.

According to one embodiment, a coating head includes a coating bar, nozzles, a first member, second members, third members, elastic members, and a position controller. The coating bar faces a coating member. The nozzles supply a liquid toward the coating bar. The first member includes first recesses. A portion of the nozzles is between the first recesses and the third members. The portion of the nozzles and the third members are fixed to the first member by the second members. The elastic members are located in at least first, second, or third positions. The first position is between the third members and the second members. The second position is between the portion of the first recesses and the nozzles. The third position is between the portion of the nozzles and the third members. The position controller controls a relative position between the coating bar and the nozzles.

According to one embodiment of the invention, a coating apparatus includes a first pipe, a first pump, a first nozzle, a second nozzle, and a holder. The first pipe includes a first inflow port, a first outflow port, and a second outflow port. The first pump is configured to supply liquid toward the first inflow port. The first nozzle includes a first nozzle inflow port and a first nozzle discharge port. The first nozzle inflow port is connected to the first outflow port. The first nozzle discharge port is configured to discharge the liquid passing through the first pipe. The second nozzle includes a second nozzle inflow port and a second discharge port. The second nozzle inflow port is connected to the second outflow port. The second nozzle discharge port is configured to discharge the liquid passing through the first pipe. The holder holds the first nozzle and the second nozzle. The holder is configured to form a first state and a second state. In the first state, a height of the first nozzle discharge port and a height of the second nozzle discharge port are not less than a height of the first pipe. In the second state, the height of the first nozzle discharge port and the height of the second nozzle discharge port are lower than the height of the first pipe.
