摘要： A pump assembly for a pump assembly for a dispenser container comprises a cap having a housing and a spout and a collar having a stop member. A sleeve is at least partially positioned within the collar and comprises a sleeve chamber. A plurality of resilient members are housed within the sleeve chamber. Compression of the cap causes compression of the plurality of resilient members and engagement of the cap with the stop member of the collar. The cap, the collar, the sleeve, the at least one valve, and the plurality of resilient members are comprised of a same type of recyclable material.

摘要： A pump assembly for a pump dispenser, the pump assembly comprises a cap having a housing and a spout, a collar, a sleeve, and a dip tube. The sleeve is at least partially positioned within the collar and comprises a coupling member. The coupling member comprises a shoulder, a coupling joint, and a coupling member channel extending from the shoulder to the coupling joint. The dip tube has a first end and an opposing second end, and defines a dip tube channel extending from the first end to the second end. The first end of the dip tube is configured to pivotally couple to the coupling joint and fluidly connect the dip tube channel and the coupling member channel. The dip tube channel comprises a first diameter at the first end and second diameter at the second end that is different than the first diameter.
