A dispenser includes a depressible thermal tip and a housing having a reservoir for containing a product, such as a cosmetic product or a medicinal product. The depressible thermal tip comprises a thermal applicator displaceable between open and closed positions. The thermal applicator may be depressibly coupled in a collar fixed to the housing, or the thermal applicator may be depressibly coupled in a button depressibly coupled in a collar fixed to the housing.

A rotary filling machine includes a hub member and a hub insert. The hub member includes an internal bore defining an inner surface portion with a plurality of material transfer openings. The hub insert includes a portion disposed within the bore, wherein the portion includes an outer surface portion that includes a plurality of material transfer openings. One of the hub member or the hub insert is rotatable and the other of the hub member or the hub insert is stationary.

A rotary control structure for a water valve contains: a body, a connection disk, a guide disc, a guide disc, and a stop ring. The body accommodates a control shaft and includes a receiving space and an outlet. The connection disk is connected with a positioning disc including a sector cutout. The guide disc is mounted below the positioning disc and includes a fan-shaped aperture corresponding to the sector cutout. The stop ring is mounted below the fan-shaped aperture and limits the connection disk, the positioning disc, and the guide disc in the receiving space. The body includes a limitation slot, and the control shaft includes a fixing portion and a C-retainer fitted on the fixing portion. The control shaft further includes an insertion retained with a coupling groove of the connection disk, and the connection disk includes a rib configured to urge the positioning disc to rotate.
