Dispensing device

Dispensing device according to any preceding claim, characterized in

• that the pump means (14) defines a rear part of the pump chamber (10) and includes an annular portion (14c) which on one side is sealed by a semi-spherical or substantially semi-spherical portion (14a),
• that the semi-spherical portion (14a) consists of or comprises elastic material and can be affected by the device (6) affecting the pump device (5) such that said semi-spherical portion (14a) is pressed into the pump chamber (10) from a normal shape for pumping foodstuff (4) out of the pump chamber (10) through the dispensing pipe (15),
• that the semi-spherical portion (14a) is provided to return to its normal shape when the influence from the device (6) affecting the pump device (5) ceases, such that a vacuum is generated in the connecting pipe (7) and the foodstuff container (2) for drawing foodstuff (4) from the foodstuff container (2) and through the connecting pipe (7) to the pump chamber (10),
• that the connecting pipe (7) is connected to a front part (9) of the pump chamber (10),
• that said front part (9) has a seat (9a) for the annular portion (14c) of the pump means (14), sealingly engageable by the annular portion (14c), and
• that a retaining ring (22) can be fixed to said front part (9) of the pump chamber (10) for retaining the pump means (14) at the front part (9).

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),
• 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),
• wherein the outer container (1) is sealable at the top by means of a cap (25) including the device (6) affecting the pump device (5) or at least parts or members thereof,
• wherein a pump handle (28) forms part of the device (6) affecting the pump device (5) and includes a vertically or substantially vertically directed member (30) which is movably journalled in vertical direction in the bearing member (27) in the cap (25) such that the pump handle (28) can be depressed and returned in vertical direction for performing pump movements, and
• wherein the device (6) affecting the pump device (5) has one or more motion transfer members (31 and/or 32) with which the vertically directed member (30) of the pump handle (28) can cooperate such that this or these motion transfer member(s) (31 and/or 32) transfer pump movements applied on the pump handle (28), to the pump means (14) and vice versa,
• characterized in
• that a motion transfer member (31) includes a lever (31a) which is pivotally journalled in the cap (25) in vertical or substantially vertical direction and which has a curved surface (31b),
• that the pump handle (28) cooperates with the curved surface (31b) and can pivot the lever (31a) in vertical or substantially vertical direction during each pump movement.
• that the pivoting movement of the lever (31a) is transferred to the pump means (14) through at least a member (32) engaging said pump means (14) and vice versa, and
• that the lever (31a) is pivotally journalled and the curvature of the curved surface (31b) is designed to provide such changing of the pump movement of the pump handle (28) that the pressure against the pump handle (28) must be increased during depression thereof in order to perform the pump movement.
