Abstract:
Dispensing device for dispensing portions of liquid foodstuff from a foodstuff container,wherein the foodstuff container (2) can be placed in an outer container (1), wherein a pump device (5) is removably mounted on the outer container (1) and includes a pump chamber (10) and a connecting pipe (7) or similar for connecting the foodstuff container (2) to the pump chamber (10), wherein the pump device (5) includes a pump means (14) which is designed such that and which can be affected by a device (6) affecting the pump device (5) such that said pump means (14) can generate a vacuum in the pump chamber (10), connecting pipe (7) and foodstuff container (2) for drawing foodstuff (4) out of said foodstuff container (2) to the pump chamber (10), and press foodstuff (4) out of the pump chamber (10) and into a dispensing pipe (15) connected thereto, wherein a first non-return valve (16), seen in the flow direction (S) of the foodstuff (4) through the pump device (5), is located upstream of the pump chamber (10) and adapted to prevent foodstuff (4) from flowing back from said pump chamber (10) towards the foodstuff container (2) during dispensing of foodstuff (4) from the pump chamber (10), and wherein a second non-return valve (17), seen in the flow direction (S) of the foodstuff (4) through the pump device (5), is located downstream of the pump chamber (10) and adapted to prevent foodstuff (4) and/or air from being drawn or sucked into the pump chamber (10) from said dispensing pipe (15) or similar when the pump means (14) draws foodstuff (4) from the foodstuff container (2) to the pump chamber (10), characterized in that at least portions (18) of a through-flow passage (13) for foodstuff (4) in the connecting pipe (7) taper in the flow direction (S) in which foodstuff (4) flows through said through-flow passage (13), that the connecting pipe (7) has an inlet pipe (11) or similar with an end portion (20) which is designed for being pressed through a flexible wall (3) of the foodstuff container (2), and that the inlet pipe (11) is connectable to a connecting member (21) provided inside the foodstuff container (2) such that the inlet pipe (11) is attached to said connecting member (21) and foodstuff (4) can flow out of the foodstuff container (2) and through a through-flow passage (12) in the inlet pipe (11) and the connecting pipe (7) into the pump chamber (10).
