  • Publication number: 20180251290
    Abstract: A brush container includes a box and two support members. The box has a U-shaped frame with two ends each having an end cover; hence, a storage space for containing a brush is defined between the U-shaped frame and two end covers. An upper cover for sealing the storage space is disposed on the top surface of the U-shaped frame. The U-shaped frame has an inner panel, an outer panel corresponding in position to the inner panel, and rib panels disposed between the inner and outer panels to allow a hollowed-out region to be defined between the inner and outer panels and two adjacent rib panels. Hence, despite being lightweight, the box has high structural strength. The two support members are slidably disposed in the storage space. Since their positions are adjustable according to the length of the brush, the two support members provide optimal support to the brush.
