Abstract: An anti-spray drinking bottle has a body, a lid, at least one check valve, a dividing mount and a guiding element. The body has a storage recess and a screwing section. The lid is detachably connected to the body and has a threaded segment connected to the screwing section, a buffering segment connected to the threaded segment and a buffering space formed in the buffering segment. The at least one check valve is mounted on the lid. The dividing board is connected to the lid, is mounted in the body and has a dividing board, a sidewall, an outlet pipe and an abutting segment. The guiding element is connected to the dividing mount, is mounted in the body and has an elongate straw tube connected to the outlet pipe.

Abstract: A tumbler with a bi-layer structure has a collision-resistant outer tumbler body, a glass inner container and a lid. The collision-resistant outer tumbler body is made of plastic. The glass inner container is made of glass, is mounted in the collision-resistant outer tumbler body to form a bi-layer structure, and has a container space. The lid is mounted on the collision-resistant outer tumbler body and the glass inner container and has a combining base combined with the collision-resistant outer tumbler body and the glass inner container, an opening unit mounted in the combining base and communicating with the container space, and a closing cap combined with the combining base and selectively closing the opening unit.

Abstract: An air inlet is mounted in a baby bottle and has a valve and an air-inlet tube. The valve has a body, an outer ring and an inner ring. The body has a chamber, multiple separating blocks and multiple liquid channels. The separating blocks are formed on the body and each has a vent. The liquid channels are formed through the body between the separating blocks and communicate with the chamber. The outer ring is formed around the chamber to separate the chamber and the vents. The inner ring is formed on an inner end of the body around the vents and has multiple air inlets. The air-inlet tube is mounted detachably on the inner ring of the valve. Therefore, liquid flows through the liquid channels and the chamber, but air flows through the air inlets and the vents to the air-inlet tube to ensure smooth operation.

Abstract: A feeding mouthpiece has a body and a tube. The body is hollow, a resilient material and has two ends, a teat and a seal. The teat is formed on one end of the body, has an opening and corresponds to a mouth of young. The seal is formed on the other end of the body and has a sealing surface. The tube is formed through and protrudes from the sealing surface of the seal, is tapered to a transverse ridge and has an outer surface, a proximal end, two gables and an air valve. The air valve is a slit and may be formed along the transverse ridge or longitudinally on the outer surface of the tube. When the feeding mouthpiece is mounted with a bottle, the air valve prevents leakage and is easily cleaned without tearing or breaking the feeding mouthpiece.
