  • Patent number: 7059496
    Abstract: The present invention relates to a shaker for sprinkling granules, preferably salt. The shaker (1) comprises a screen-like member (7) which is mounted movable in vertical direction relative to such lower parts (5) of the shaker (1) which define a lower space (8) in which granules (2) are collected or vice versa, for being able to set the screen-like member (7) such that downwardly directed portions (7a) thereof can be set at different distances (e.g. A or B) from the bottom (9) of the lower space (8). Thereby, it is achieved that the lower space (8) can be brought to contain different amounts of granules (2).

  • Patent number: 6598764
    Abstract: The present invention relates to a device for discharge of a paste-like product, e.g., mayonnaise or similar, from a package of flexible material, and a package for use with the device. The device includes an outer member (9) and an inner container (24) provided in the outer member (9) and in which the package (2) is located. The inner container (24) is displaceable in a discharge and in a return direction (M, R) together with the package (2). Front parts (29) of the package (2) engage a front end side (28) of the outer member (9) during discharge of the product (3) and are disengaged when the inner container (24) with the package (2) is displaced in the return direction (R), whereby the discharge pressure on the product (3) and thereby, the discharge thereof, ceases.

  • Patent number: 6257844
    Abstract: A pump device for pumping liquid foodstuff includes a pump housing having an inlet and an outlet for pumping the foodstuff therethrough. A pump body is disposed within the pump housing having an elastic member which contains a predetermined volume of pressurized liquid. The pressurized liquid expands the elastic member from an unpressurized normal shape to a prestressed shape. The volume of liquid contained within the elastic member remains substantially fixed while the elastic member expands from its prestressed shape to a stretched shape to pump a predetermined amount of foodstuff out of the outlet.

  • Patent number: 6109315
    Abstract: A dispensing device for dispensing portions of liquid products (5) from a package (1) with flexible walls (4) is provided. A package and a coupling device are provided. The package (1) comprises a first coupling device (6), a dispensing device (3), for dispensing portions of the liquid product (5) from the package (1), comprises a second coupling device (19) and a cassette (2), in which the package (1) can be located, comprises a third coupling device (20). The first coupling device (6) of the package (1) and the third coupling device (20) of the cassette (2) are interconnectable without opening the package (1) and, when said first and third coupling devices (6 and 20) are interconnected, the first coupling device (6) of the package (1) can be connected to the second coupling device (19) of the dispensing device (3) such that the package (1) is opened.

  • Patent number: 5730327
    Abstract: The present invention relates to an arrangement for portioning or dispensing viscous material from a pack, whereby the pack is positionable in an outer container and a portioning or dispensing unit includes a non-return valve which prevents the material from flowing back to the pack during portioning or dispensation. For being able to quickly place the pack in the outer container and quickly and safely lock a retaining portion as well as ensure than vital valve members of the non-return valve are not damaged during handling and operation of the portioning unit, the outer container is divided in a special way into two container members, whereby retaining members of the retaining device are integrated in the container members and whereby the valve seat of the non-return valve is surrounded by the retaining members of the retaining device.

  • Patent number: 5693360
    Abstract: This invention relates to a method for manufacturing a tooth pick (1), whereby the tooth pick (1) has a blade (2) of elastic plastic material, whereby the surface of said blade (2) is provided with bristles (4) which have been brought in contact with the blade (2) through electrostatic attraction, whereby the bristles (4) have been brought to unite with the blade (2) and whereby the blade (2) comprises a brushing portion (5) provided with bristles (4) and furthermore, a cleaning tip (6) without or substantially without bristles. In order to also permit cleaning of very narrow interdental spaces by means of this tooth pick (1) without damaging the gums, the cleaning tip (6) has in its full length or at least substantial parts thereof a rectangular cross section.
