Abstract: A sterile spray pump, including a main piston (30), a spray head (40), and a secondary piston (50) fixed inside the spray head (40) and mounted in a vertically movable manner on the main piston (30). A first compression space (10) and a second compression space (20) are formed between the secondary piston (50) and the main piston (30); a main liquid suction cavity (301) communicating with the inner cavity of a container and an air supply port (302) communicating with the main liquid suction cavity (301) are provided in the main piston (30); the air supply port (302) communicates with the second compression space (20), a filter element (601) is fixedly provided in the air supply port (302); the secondary piston (50) includes a secondary liquid suction cavity (501) communicating with the main liquid suction cavity (301), a first exhaust member (502), and a second exhaust member (503).

Abstract: The present disclosure provides a feeding container device, including a bottle body having a bottle inner cavity, a first cover body at least partially disposed inside the bottle inner cavity and fixedly connected to the bottle body, a second cover body at least partially disposed inside the bottle inner cavity and having a cover inner cavity, a sealing ring disposed inside the bottle inner cavity and blocking the cover inner cavity, and a feeding device fixedly connected to the second cover body, the second cover body is mounted to the bottle body, the sealing ring is detachably connected to the second cover body and abuts the first cover body; when the second cover body moves away from the bottle body, the first cover body causes the sealing ring to separate from the second cover body, and the first sealed chamber communicates with the second sealed chamber.

Abstract: The present disclosure relates to a drip device, including a drip bottle having a bottle mouth facing downward, since the bottle mouth faces downward, the liquid in the drip bottle is charged into the first connecting tube, the infusion channel, the piston chamber, and the infusion channel when the pressing head is not pushed upward, the plug blocks the drip port, and the liquid cannot flow out from the drip port. When the pressing head is pushed upward to move the pressing head upward relative to the connecting cover, the piston head inserts into the piston chamber to separate the infusion channel from the piston chamber, the pressing head continues to move upward, the volume of the piston chamber is compressed, the liquid in the piston chamber will flow back to the drip bottle through the liquid outlet, and the volume of the infusion channel is also compressed.

Abstract: A spray bottle cap comprising a base lid, a pressing head and a protective cap. An upper end of an inner wall of the base lid is provided with a first limit rib and a first guide groove penetrating the first limit rib. The pressing head connects to the upper end of the base lid, and comprises a outlet rob, a pressing handle and a connection portion, where the outlet rod is provided with an outer thread, the lower end of the connection portion is provided with a first limit flange and a protrusion portion, and the pressing handle is provided with an anti-reversion snap parent body; the first limit flange is arranged under the first limit rib, and the protrusion portion is up-down slidable along the first guide groove and is supportable on the upper end face of the base lid. The protection cap is a double-layer structure covering the outside of the outlet rod.
