The present invention relates to a disposable dispensing system comprising - a collapsible container (400) for liquid material and - a pump (1) being sealingly connected to the collapsible container (400) for withdrawal of liquid material from the container (400) during collapse thereof, - the pump (1) comprising - a housing (400) forming a chamber (110) and a dispensing opening (120), wherein the pressure in the chamber (110) may be varied for pumping liquid from the container (400) to the chamber (110), and further from the chamber (110) to a dispensing opening (120), - and a regulator (200) being fixedly arranged in the chamber (110) for regulating a flow of liquid between the container (400) and the chamber (110), and between the chamber (110) and the dispensing opening (120), - wherein the pump (1) may assume a closed position, in which a volume of liquid is drawn from the container (400) to the chamber (110) by means of a negative pressure created in the chamber (110), - and a dispensing position, in which a volume of liquid is drawn from the chamber (110) to the dispensing opening (120). The dispensing system is characterized by the pump (1) consisting of plastic materials; and the pump (1) comprising - return means automatically returning the pump (1) from said dispensing position to said closed position, whereby the return means uses the resiliency of said plastic material for overcoming a negative pressure created in the collapsible container (400) during emptying thereof.
L'invention concerne un système de distribution jetable comprenant: - un conteneur (400) pliable destiné à des matières liquides et - une pompe (1) reliée de manière étanche audit conteneur (400) afin d'extraire les matières liquides du conteneur (400) durant son pliage. La pompe (1) comprend: -un logement (400) formant une chambre (110) et une ouverture de distribution (120), la pression dans la chambre (110) pouvant être modifiée pour pomper le liquide du conteneur (400) vers la chambre (110), et au-delà de la chambre (110) vers une ouverture de distribution (120), - et un régulateur (200) disposé fixement dans la chambre (110) destiné à réguler le débit de liquide entre le conteneur (400) et la chambre (110), et entre la chambre (110) et l'ouverture de distribution (120), - la pompe (1) pouvant se trouver en position fermée, dans laquelle un volume de liquide est extrait du conteneur (400) vers la chambre (110) au moyen d'une pression négative créée dans la chambre (110), - et en position de distribution, dans laquelle le volume de liquide est extrait de la chambre (110) vers l'ouverture de distribution (120). Le système de distribution est caractérisé en ce que la pompe (1) est faite de matières plastiques; et la pompe (1) comprenant: des moyens destinés à remetttre automatiquement la pompe (1) de la position de distribution à la position fermée, ces moyens utilisent la résilience de la matière plastique en vue de surmonter une pression négative créée dans le conteneur (400) pliable durant son déchargement.
