Abstract: A cosmetic powder box, belonging to cosmetic powder box, includes a bottom box; a box base, one side of the box base is rotationally connected to the bottom box, and the box base is sleeved in the bottom box through rotating around the bottom box; a box cover, one side of the box cover is rotationally connected to the box base; when the box base is sleeved in the bottom box, the box cover rotates around the bottom box, such that the box cover is buckled with the bottom box, and a mounting hole is defined in a center of the box cover; a mounting component detachably fastened in the mounting hole; wherein the bottom box, the box base and the box cover are of an integrated structure.

Abstract: A sub-assembly and a method for manufacturing the sub-assembly are disclosed. The sub-assembly includes a shell, driver and a body. The shell is open at both ends and has a smooth inner wall. The driver has first and second portions with a channel arranged along an inner wall. The first portion of the driver is fixed to the shell. The body has an open end and a closed end. A set of flexible appendages compressively contact an inner wall over the second portion of the driver. The shell, driver and body are concentric tubes. A sub-assembly of a product dispenser is produced by pressing the first portion of the driver into the shell and inserting the body into the driver such that the flexible appendages compressively contact the inner wall of the driver. A product holder or cup can be introduced in the body to complete the assembly.

Abstract: A dispenser with a transfer assembly is arranged to efficiently transfer a stored liquid from a reservoir in a body of the dispenser to an applicator. The transfer assembly includes an adapter, applicator base, piston and a bias member. The adapter is in contact with the body and has a central member with orifices to fluidly couple the applicator base to the reservoir. The applicator base is supported by and extends beyond the adapter. The applicator base forms a cavity for housing the piston and the bias member. A tubular member of the applicator base supports an applicator. The piston includes a passage that conveys the stored liquid from the cavity to the applicator. The bias member keeps the head of the piston against a surface of the central member. When stored liquid is under a pressure that exceeds a bias force, displacement of the piston, opens a seal.

Abstract: A dispenser with a hollow body, a sleeve, a cap and sealing element is disclosed. The hollow body is open at both ends with sealing surfaces proximal to a first end. The sleeve is fixed to and extends beyond the hollow body. The sleeve has a complementary region proximal to the sealing surfaces. The cap has a closed end and an opposed open end defined by a wall with an irregular surface proximal to the open end. A sealing element is located in a cavity defined by the sealing surfaces of the hollow body, the complementary region of the sleeve and the irregular surface of the cap. The sealing element is arranged with sets of surfaces that are in contact with respective surfaces of the sleeve and the body at all times and is further in contact with a third set of surfaces when the cap is attached to the sleeve.
