연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

A foam dispenser is formed by modifying a standard reciprocating piston liquid pump having a reciprocating piston that is pressed to dispense liquid at an outlet. A holding chamber membrane surrounds the reciprocating piston and the outlet to define a holding chamber such that liquid dispensed at the outlet gathers at the bottom of the holding chamber. Pressing on the holding chamber membrane actuates the reciprocating piston liquid pump to dispense liquid into the holding chamber and also forces air and a portion of the liquid gathered in the holding ch...

1. A foam dispenser: a container retaining a foamable liquid for dispensing;a reciprocating piston liquid pump having a reciprocating piston with a pump outlet, said reciprocating piston liquid pump communicating with said foamable liquid in said container, said reciprocating piston liquid pump being actuated by reciprocation of the reciprocating piston to dispense a dose of foamable liquid at said pump outlet;a holding chamber membrane defined by a floor, a cover, and a sidewall and surrounding said reciprocating piston, said reciprocating piston liquid pump extending through said floor of said holding chamber membrane;a separation membrane positioned between said reciprocating piston and said holding chamber membrane to define a holding chamber between said separation membrane and said holding chamber membrane, said separation membrane surrounding said reciprocating piston so as to permit a dose of foamable liquid dispensed at said pump outlet of said reciprocating piston to enter said holding chamber and collect on said floor, said cover being biased away from said floor to establish an expanded volume of said holding chamber, and movable toward said floor to establish a compressed volume of said holding chamber;a dispensing spout having a spout inlet communicating with said holding chamber proximate said floor and extending to a spout outlet;a foam media in said dispensing spout between said spout inlet and said spout outlet, wherein, when said cover is moved sufficiently toward said floor, said reciprocating piston liquid pump is actuated and dispenses a dose of foamable liquid into said holding chamber, and the volume of said holding chamber decreases, forcing air and foamable liquid into and through the dispensing spout and foam media to said spout outlet. 2. The foam dispenser of claim 1, wherein said container includes an opening sealed by a cap, said reciprocating piston liquid pump extending through said cap to communicate with said foamable liquid. 3. The foam dispenser of claim 2, wherein said separation membrane is secured to said reciprocating piston proximate said pump outlet and secured to said cap such that said separation membrane moves with said reciprocating piston and seals said reciprocating piston liquid pump against contact with doses of foamable liquid dispensed at said pump outlet of said reciprocating piston liquid pump. 4. The foam dispenser of claim 3, wherein said floor of said holding chamber membrane is secured to said separation membrane proximate said cap. 5. The foam dispenser of claim 1, wherein said sidewall of said holding chamber membrane is a bellows sidewall. 6. The foam dispenser of claim 1, wherein said foam media is a cartridge bounded by mesh screens. 7. A method for making a foam pump from a liquid dispenser that includes (a) a container for holding a liquid and (b) a reciprocating piston liquid pump communicating with the liquid in the container and providing a pump outlet in a reciprocating piston portion of the reciprocating piston liquid pump, wherein actuation of said reciprocating piston liquid pump is achieved by reciprocating movement of the reciprocating piston portion and dispenses a dose of the liquid at the pump outlet, said method comprising the steps of: surrounding the reciprocating piston with a holding chamber membrane having a floor, a cover and a collapsible sidewall;positioning a separation membrane between the reciprocating piston and the holding chamber membrane to define a holding chamber between the separation membrane and the holding chamber membrane;securing a dispensing spout to the holding chamber membrane proximate said floor, the dispensing spout having a spout inlet communicating with the holding chamber proximate the floor and extending to a spout outlet; andpositioning a foam media in the dispensing spout between the spout inlet and the spout outlet, the holding chamber membrane being sealed such that pressing the cover of the holding chamber membrane toward the floor thereof actuates the reciprocating piston liquid pump to dispense a dose of foamable liquid into the holding chamber, and the volume of the holding chamber decreases, forcing air and foamable liquid into and through the dispensing spout and foam media to the spout outlet. 8. A foam dispenser comprising: a container retaining a foamable liquid;a reciprocating liquid pump;a cap connected to the liquid pump for securing the liquid pump to the container;the liquid pump having a dip tube extending into the container and a dispensing nozzle opposite the dip tube;a holding chamber surrounding the dispensing nozzle and secured to the cap;the holding chamber having a resilient membrane and a floor;the holding chamber having an expanded volume and a compressed volume;an outlet passage connected to the resilient membrane and the floor; anda foaming media located in the outlet passage. 9. The foam dispenser of claim 8 further comprising a separation membrane separating a stem of the reciprocating liquid pump from liquid dispensed from the dispensing nozzle. 10. The foam dispenser of claim 8 wherein liquid dispensed from the dispensing nozzle builds up on the floor and is forced through the foaming media and outlet passage by air pressure caused by the holding chamber moving from an expanded volume to a compressed volume. 11. The foam dispenser of claim 8 wherein the resilient membrane is in the form of a bellows. 12. The foam dispenser of claim 8 wherein the outlet nozzle opens substantially downward. 13. The foam dispenser of claim 8 wherein air may enter into the container through an aperture in the housing of the liquid pump. 14. A foam dispenser comprising: a container retaining a foamable liquid;a reciprocating liquid pump;a cap connected to the liquid pump for securing the liquid pump to the container;the liquid pump having a dip tube extending into the container and a dispensing nozzle opposite the dip tube;a holding chamber surrounding the dispensing nozzle and secured to the cap;the holding chamber having a resilient membrane and a floor;the holding chamber having an expanded volume and a compressed volume;an outlet passage connected to the floor of the holding chamber;a foaming media located in the outlet passage. 15. The foam dispenser of claim 14 further comprising a separation membrane separating a stem of the reciprocating liquid pump from liquid dispensed from the dispensing nozzle. 16. The foam dispenser of claim 14 wherein liquid dispensed from the dispensing nozzle builds up on the floor and is forced through the foaming media and outlet passage by air pressure caused by the holding chamber moving from an expanded volume to a compressed volume. 17. The foam dispenser of claim 14 wherein the resilient membrane is in the form of a bellows. 18. The foam dispenser of claim 14 wherein the outlet nozzle opens substantially downward. 19. The foam dispenser of claim 14 wherein air may enter into the container through an aperture in the housing of the liquid pump. 20. The foam dispenser of claim 14 wherein the foaming media comprises one or more screens.
