DETAILED DESCRIPTION
(16) FIG. 1 shows the view of the dispenser 1 with the rotary gate feeder 2, the plunger 3, the fastener 4, and the tube or bottle neck 10.
(17) FIG. 2 shows a cross section of the dispenser 1, the one-piece rotary gate feeder 2, which is represented with the fixed and snapped-in intake and discharge valves 6 with outlet openings 7 and the plunger 8 as a cylindrical plunger variant. The snap fastener 9, which includes the complete rotary gate feeder. The product-directing 20 re-circulation valve 11 is integrated into the tube or bottle neck 10. Additionally, a metering chamber that is not identified more specifically is shown, which would hold the cream or the gelatinous product.
(18) FIG. 3 shows a cross section of the dispenser 1 as a closed variant, i.e., the plunger 8 that abuts the plunger seal seat 5, whether spherical or cylindrical, runs toward the slotted outlet wall 12 in the intake or discharge valve 6. The snap elements 13 brace the discharge valve 6 with the rotary gate feeder 2. The bottle or tube neck 10 is provided a slotted re-circulation valve 11. The slot 14 is clearly visible here.
(19) FIG. 4 shows a horizontal section in the area of the rotary gate feeder 2 as a T-shaped geometry 17, the slotted intake or discharge valve 6 with the slot 12, and the axis mounting 15 and axis with fastener wall 16.
(20) FIG. 5 shows the subassembly 18, rotary gate feeder 2 with fastener 9 in cross section with the plunger 3 in the seal seat 5.
(21) FIG. 6 shows the subassembly 19 with the bottle or tube neck 10 and the re-circulation valve 11 as a flow-aligned variant 20.
(22) FIG. 7 shows a cross section of the open variant 7 of the dispenser 1 with a shearing, sealing, and latching element 21 for the rotary gate feeder 2 in the re-circulation valve 11 in order to shear off the extracted product thread of cream or gelatinous product in the metering chamber upon twisting the rotary gate feeder 2.
(23) FIG. 8 shows a horizontal section of a variant whereby the rotary gate feeder 2 is constructed of two basins 22 and 23. The basins 22, 23 are held together with the half basin linking elements 24. In this version, a separation is visible on the outer area of the rotary gate feeder 2.
(24) FIG. 9 shows an example in longitudinal section through the tube with the re-circulation valve 11 integrated into the tube neck 10. The rotary gate feeder 2 is with the basins 22 and 23 and the plunger 3 and the intake and discharge valves 6.
(25) FIG. 10 shows FIG. 9 in cross section through the tube neck 10 with the rotary gate feeder brace 25 and the integrated re-circulation valve 11 in the tube neck 10. The rotary gate feeder 2 with the two basins 22 and 23 and the intake and discharge valve 6 as well as the plunger 3 integrated into the tube neck 10.
(26) FIG. 11 shows a cross section through the rotary gate feeder 2 with the two basins 22 and 23.
(27) FIG. 12 shows a cross section through a rotary gate feeder variant with the basins 22 and 23 with a convex discharge valve 26 and spherical plunger 3. As such, the spherical plunger 3 is not spherical unto itself but rather has a rounded end area that works in conjunction with the intake and discharge valve 6 in the particular position of the rotary gate feeder 2. In this context, working in conjunction means that the spherical plunger 3 engages with its rounded end areas in a form-locking manner in the intake and discharge valve 6 and extracts the cream or gelatinous product from the metering chamber in the extraction position.
(28) Extraction position means that the rotary gate feeder 2 with the discharge valve is directed away from the tube and the intake valve is directed toward the tube, whereby the cream or gelatinous product is already in the metering chamber and is pressed by the rounded plunger 3 out of the discharge valve, whereby the intake and discharge valve 6 is slotted and consequently flexible, which enables the form closure between the rounded plunger 3 and the intake and discharge valve 6.
(29) FIG. 13 shows a cross section of a one-piece rotary gate feeder 2 with the endpiece 27, the fastener 4, and the tube 10 with mounted re-circulation valve 11.
(30) FIG. 14 shows a cross section of a one-piece rotary gate feeder 2 with the valve endpiece 27 and the fastener 4, which also produces the tube neck 10 for the tube.
