  • Patent number: 11945755
    Abstract: A heater includes a base body, terminal and joining layer. The base body is made of ceramic. The joining layer contains metal as a principal ingredient and is located between the base body and the terminal. The base body includes a first surface and second surface. The first surface faces an outer side of the base body and includes at least one of a region which is superimposed on the terminal and a region which is located on a periphery of the terminal. The second surface intersects with the first surface and is located on the side closer to an internal portion of the base body on the side away from the first surface. The joining layer extends from the terminal and first surface up to the second surface.

  • Patent number: 7985033
    Abstract: A cosmetic application device includes the application stick and the application portion having the brush fixedly mounted at the end of the application stick by the cylindrical capsule, wherein corner portions of the inner surface and the outer surface of the capsule are chamfered so as not to leave sharp edges. Also, the thin and soft protection tube is disposed between the brush and the capsule with the end of the tube extending slightly beyond the end of the capsule, thereby preventing the brush from being bent at an acute angle to avoid broken hair of the brush.

  • Patent number: 7337787
    Abstract: A container for storing make-up powder, such as white powder or powder foundation and an application member such as a powder puff includes a structure wherein a make-up material-storing compartment for storing make-up powder has an intermediate lid which is engaged with a container. At least a part of a partition portion of the intermediate lid is formed with an elastic material, with numerous small cuts vertically formed through the partition portion, thereby enabling make-up powder to pass through the small cuts opened by extending the partition portion. The small cuts are arranged in a direction crossing a direction of extension of the partition portion under a normal use condition.
