Abstract
Description
1 / 19 Distributor for the distribution of fluid masses. Field of Technology.
[001] The invention relates to a dispenser for dispensing fluid masses, for example, liquid or porous, with a reservoir for receiving the mass, with a dispensing pump configured in a modular construction, wherein the dispenser has a longitudinal axis, wherein the dispenser pump has a channel on the inlet side and one on the outlet side and a pump chamber delimited on the inlet and outlet sides by valves, as well as a top piece, wherein the top piece has a dispensing outlet and a dispensing channel, wherein the dispensing pump is insertable into the reservoir and in that case is connected to the container by means of a locking connection, wherein the pump chamber is formed by a piston and a pan-shaped part which has a bottom of the pan-shaped part and a wall of the pan-shaped part,The piston is housed in a pan-shaped section with a sliding motion to achieve a pump stroke. The pan-shaped section also features mounting points on the outer wall for secure attachment to the inner wall of the reservoir. The pump connection is reinforced by two locking flanges spaced vertically apart and radially protruding outwards along a longitudinal section of the dispenser. State of the Art
[002] A distributor with a modular and replaceable distributor pump configuration is known, for example, from document EP 1015340b1. Through this configuration, a pump is indicated. Petition 870260049464, dated 05 / 25 / 2026, page 5 / 60 2 / 19 compact distributor, which can be used with a plurality of distributors that are freely configurable in its top piece and reservoir.
[003] From document DE 10 2008 030 118 A1, a distributor with a locking link is known, wherein in particular the locking link is provided by means of a locking flange. The locking link is not considered satisfactory in all respects.
[004] From document DE 100 330 040 A1, a distributor is known in which the pump chamber has a pan-shaped part, which is connected to an inner wall of a reservoir. During a pumping process, the mass is pressed into a starting channel, which simultaneously elastically pushes back a valve that closes a supply opening of the starting channel, the valve being associated with a free space on the opposite side of the mass. To prevent overpressure in the free space, an air path is provided from the free space to the inner space formed by the pan-shaped part and the piston part, which, in turn, has an air path outwards. The piston part is driven directly into a wall part that forms an outer surface of the pan-shaped part. Summary of the Invention
[005] In relation to the state of the art described above, the invention sets out the objective of improving a dispenser of the type in question advantageously in the sense of a fixation.
[006] A possible solution to achieve the objective, according to a first inventive idea, is given in a dispenser in which it is considered that both locking edges are configured with an introduction rounding on the reservoir side, but on the top piece side with a backing surface that extends Petition 870260049464, dated 05 / 25 / 2026, p. 6 / 60 3 / 19 substantially horizontal in relation to the longitudinal section.
[007] As a result of the proposed configuration, a dispenser is created that is particularly safe in terms of operation. The dispenser pump can be combined with a plurality of different reservoirs without difficulty during assembly according to production. When a combination is made and the dispenser pump is locked in the reservoir, a virtually non-releasable connection is given with safe operation.
[008] With regard to the production of the dispenser and the first connection between the dispensing pump and the reservoir, it is further ensured that the dispensing pump can be connected to each reservoir in a suitably configured manner with respect to the connection, and this with a comparatively simple configuration of the connection configurations on the dispensing pump and the container. Therefore, depending on the production, one can choose between several dispensing pumps or several reservoirs, with great freedom, up to the effective connection of the dispensing pump with the reservoir.
[009] On the other hand, the locking flanges, spaced apart and projecting radially outwards in a vertical direction, with an inlet rounding on the reservoir side and a corresponding bearing surface extending on the end piece side, ensure a reinforced locking connection between the distributor pump and the reservoir. Once the connection is made, the distributor pump remains secure in the container, even under a high load, especially a high external load. Thus, for example, even a lateral load considered in relation to the longitudinal axis of the distributor (correspondingly radially outwards) on the locking connection cannot cause an effect that breaks the locking connection. Even with a possible use of the distributor pump in a distributor configuration, for example, Petition 870260049464, dated 05 / 25 / 2026, p. 7 / 60 4 / 19 on a massage head, the distributor pump cannot be separated from the reservoir, especially not by usual manual force, due to the reinforced locking link.
[0010] Furthermore, as a consequence of this configuration, it can also be ensured that the distributor pump is not separated from its respective reservoir without special, extraordinary effort and that no other reservoir is associated with it according to the arrangement.
[0011] The reinforcement is preferably chosen in such a way that, in relation to the known locking link, especially the known locking link of the prior art mentioned above, a force of at least 1.5 times to 3 or 5 times is required to undo the locking link.
[0012] The locking mechanism is preferably chosen in such a way that it cannot be undone by usual manual force, i.e., without tools and without destruction.
[0013] Other features of the invention are explained below, also in the description of Figures, often in their preferred association with the object of claim 1 or with the features of other claims. But they may also be important in association with only individual claims of claim 1 or of the respective other claim or independently.
[0014] The locking flanges may extend in relation to the longitudinal axis in an annular shape, correspondingly through the entire circumference of the part of the distributor pump that has the locking flange or of the reservoir. The counter-locking part, correspondingly the reservoir or the distributor pump, then has locking grooves preferably configured in a corresponding manner and adapted to the cross-sections. These may extend throughout the Petition 870260049464, dated 05 / 25 / 2026, p. 8 / 60 5 / 19 circumference, as preferably also.
[0015] Alternatively, the locking edges, possibly also the locking grooves, may extend only over a partial section of the circumference, and possibly a plurality of locking edges and locking grooves may be provided beyond the circumference.
[0016] The spacing of the locking edges, observed in an axial direction, preferably corresponds to 1 to 5 times, more preferably it may correspond to 1.5 to two times the length of a locking edge considered in the same direction.
[0017] The two locking edges may have identical cross-sections; this applies both to their geometric configuration and to their axial and radial dimensions. In addition, the locking edges may also have different cross-sections, which also differ in relation to their geometric configuration and / or their radial and / or axial dimensions.
[0018] The rounded insertion point, which is configured on the respective locking edges on the reservoir side, acts as a support during the fixing of the distributor pump to the reservoir. As a consequence of the rounded insertion point, an edge surrounding the container opening, as well as the locking groove initially configured in the fitting direction, transitions advantageously.
[0019] The provided bearing surface extending substantially horizontally relative to the longitudinal cut in the two locking edges on the end piece side cooperates with a counter-bearing surface of the locking groove in the locked fixing position of the distributor pump in the reservoir, which preferably extends in the same orientation, in such a way Petition 870260049464, dated 05 / 25 / 2026, page 9 / 60 6 / 19 also corresponds substantially horizontally.
[0020] As a result of this configuration, the locking edges are shaped like a backhook, which supports the introduction and placement of the distributor pump in the locking position, but prevents the locking from being undone.
[0021] The invention also relates to a distributor for distributing fluid masses, for example, liquids or pastes, with a reservoir for receiving the mass and a distributor pump, wherein the distributor has a longitudinal axis, wherein the distributor pump has an inlet channel and an outlet channel and has a pump chamber delimited by valves on the inlet and outlet sides, as well as a top piece, wherein the top piece has a distribution outlet and a distribution channel, wherein the pump chamber is formed by a piston and a bowl part, which has a pad bottom and a bowl wall, wherein the piston is received in a sliding manner in the bowl part, to obtain a pump stroke and a return spring acts between a piston part connected to the piston and the bowl bottom, wherein the piston part has a support cover,The replacement spring rests against the bottom of the pan and, together with the pan section, forms a first internal space, the volume of which changes when the pump is activated. This first internal space is further surrounded by a second internal space, formed between the top piece, the pan section, and the piston section.
[0022] In a known dispenser of document DE 10330040 In A1, a first internal space is connected to a second internal space located above it. When compression occurs, however, the volume in the first and second spaces is only compressed, and still... Petition 870260049464, dated 05 / 25 / 2026, page 10 / 60 7 / 19 The second internal space is further reduced by means of a closing mechanism when the distributor is opened, and the pressure is also increased in the first internal space.
[0023] In a known distributor of document DE 19938798 A1 also provides for only two internal spaces arranged in series connection, which are not yet connected through a ventilation opening. The same applies to the known distributors from documents DE 3900267 A1 and EP 1015340 B1. Starting from a distributor, as known, for example, from document DE 102008030118 A1, the invention deals with establishing the objective of ensuring advantageous handling.
[0024] This objective is achieved in object d of claim 9, whereby an air path is configured in the back cover to prevent pressure buildup in the first internal space during pump actuation.
[0025] Through the proposed air path, an air cushion that may eventually form between the bowl part and the piston part during distributor pump actuation can be avoided, especially when reducing the volume of the pump chamber. A consequent formation would lead to an increase in the actuation force for displacement of the top piece in addition to the reset force of the reset device. Through the given air path, this problem is avoided. Through the air path in the preferred configuration, the internal space that forms between the bowl part and the piston part is exposed to ambient air pressure regardless of the position of the top piece relative to the distributor pump.
[0026] The second internal space, which surrounds the first internal space, is connected to the surrounding air and thus under the same pressure between the top piece and the head piece, by virtue of a Petition 870260049464, dated 05 / 25 / 2026, page 11 / 60 8 / 19 gap that usually exists. Air flowing from the first internal space to the second internal space during actuation, to avoid overpressure in the first internal space, can escape easily to the surrounding environment without a significant pressure increase occurring in the second internal space.
[0027] The air path, in one possible configuration, may be given in a kind of perforation in the upper closing wall of the piston part. Also, the closing wall may be almost completely closed outside the regions constructively required for retention, for example, of a piston part wall and a connection to the starting channel, so that a correspondingly enlarged air path can be established. Thus, the closing wall of the piston part may also be configured, for example, in the form of a geometric radius in relation to a top view, where the longitudinal axis is represented as a point, and the air paths result between the geometric radii. Brief Description of the Drawings
[0028] The invention is further explained in detail below with the aid of the accompanying drawing, which represents only one embodiment. The following are shown:
[0029] Figure 1: a distributor of the type in question in longitudinal section representation;
[0030] Figure 2: Enlargement of region II in Figure 1:
[0031] Figure 3: Enlargement of region III in Figure 1:
[0032] Figure 4: a part of the distributor piston in individual perspective representation. Description of Implementation Methods
[0033] It is represented and described, initially in relation to Figure 1, a dispenser 1 for disposing of a reservoir 2.
[0034] Reservoir 2 is configured, in the examples of Petition 870260049464, dated 05 / 25 / 2026, page 12 / 60 9 / 19 embodiment represented, as a substantially cylindrical body, with a central longitudinal axis x, which, at the corresponding association position, also passes through the distributor 1, preferably in the form of a rotation axis.
[0035] Reservoir 2 has a reservoir chamber for receiving a mass M to be distributed. This reservoir chamber 3 is delimited on the bottom side by a follower piston 4.
[0036] In the opening of reservoir 2, which points upwards, in an assembled state, reservoir 2 has the distributor inserted and fixed to reservoir 2.
[0037] Distributor 1 consists substantially of a top piece 5 and a distributor pump 6.
[0038] The distributor pump 6 initially has a piston body 7 with a piston 8 and a pan part 9 with a pan bottom 28 and a cylindrical section 10. In this case, the piston 8 is received in a sliding manner along the longitudinal x-axis in the cylindrical section 10, and between the piston 8 and the cylindrical section 10, and further limited by the pan bottom 28 and the pan part 9, a pump chamber 11 is formed.
[0039] The pan part 9 is configured in a replaceable manner to adapt to different reservoirs 2, especially to different opening diameters and / or cross-sections of the reservoir 2.
[0040] The pump chamber 11 connects an inlet channel 12 and an outlet channel 13, both channels being separable from the pump chamber 11 by means of a respective valve 14 on the inlet side and a valve 15 on the outlet side.
[0041] The two valves 14 and 15, shaped as check valves, are mounted in such a way that they open in the same direction, that is, towards the distributor.
[0042] Between piston section 7 and cylindrical section 10 is Petition 870260049464, dated 05 / 25 / 2026, p. 13 / 60 10 / 19 a replacement device 16 is provided, here in the form of a cylindrical spring. In this case, it may be a conventional metallic cylindrical spring. Alternatively, a spring made of a synthetic material with corresponding elastic replacement capacity may also be provided here, for the purpose of creating an all-plastic type distributor.
[0043] The replacement device 16 is further arranged in such a way that it rests on the bottom of the pan 28 in a preferably concentric arrangement with respect to the longitudinal axis x, on the one hand, and acts against an upper closing wall of the piston part 7, on the other hand, in such a way that the top piece 5 is stressed in the direction of an enlargement of the pump chamber with the piston part 7 and the piston 8, to refill the pump chamber 11 after a pump stroke has occurred, in which the pump chamber volume is reduced.
[0044] The piston part 7 and the pan part 9 are configured respectively in a substantially pan-shaped manner. They are engaged together, together delimiting the dispenser pump 6 outwards, so that a capsule-shaped housing is formed. In a radial pan wall 17 of the pan part 9 there may also be provided at least one fixing protrusion 18, which, for example, may be configured as an annular protrusion. This fixing protrusion 18 serves to fix the dispenser spring 6 in an assembled state between the top part 5 and the reservoir 2.
[0045] In the embodiment shown, valves 14 and 15 are configured as so-called annular slot valves with an annular valve body, which covers an annular slot 19 or 20 of the inlet or outlet channel 12, 13.
[0046] Through the radially symmetrical configuration of the distributor pump 6, a homogeneous distribution behavior is obtained. Petition 870260049464, dated 05 / 25 / 2026, page 14 / 60 11 / 19 However, the distribution pump is not limited to radially symmetrical embodiments, but may also have, in cross-section, for example, any shape, for example, square or polygonal. Instead of the annular slotted valves shown, other known check valves may also be used, for example, tilting valves.
[0047] In addition, piston 8 can be configured as a single unit with piston part 7. A kinematic inversion of the distributor pump 6 is also possible with a reversal of the opening direction of the check valves.
[0048] The top piece 5 is attached to the distributor pump 3, which has an actuation part 21 with a distribution channel 22 and a distribution outlet 23, as well as an actuation surface 24 shaped, on the upper side, preferably transversely to the longitudinal axis x, and a surrounding actuation part wall 25 possibly concentrically to the longitudinal axis x.
[0049] On the outside of the wall, preferably in a surrounding manner, the actuating part 21 is driven axially through the pan wall 17 of the pan part 9 above its partial actuating wall 25.
[0050] The dispensing channel 22, which initially receives the longitudinal axis x centrally and along its longitudinal extension, in the example embodiment shown, is directed outwards, in relation to a cross-sectional representation in which the longitudinal axis x is represented as a line, for example, according to Figure 1, including an angle preferably obtuse with respect to the longitudinal axis x, and empties into the dispensing outlet 23. The dispensing channel 22 is inserted in a watertight manner into the outlet channel 13, with the piston 8, the piston part 7 and the dispensing channel still in the position of use. Petition 870260049464, dated 05 / 25 / 2026, page 15 / 60 12 / 19 together with the actuating part 21 cooperate for common displacement along the longitudinal x-axis. Correspondingly, above the replacement device 16 rests the entire top piece 5 with the piston 8 fixed to it.
[0051] With the introduction of the dispenser spring 6 or the dispenser 1 in general into the reservoir 2, a lower edge 28 of the dispenser pump 6 dips with its inlet channel 12 into the reservoir 2 and, consequently, into the reserved mass M to a depth such that direct contact is established with the mass M to be dispensed. Thus, with the placement of the dispenser 1 over the reservoir 2, preferably through the inlet valve 14 which opens during placement as a result of pressure demand, the mass M can spread to the pump chamber 11 for initial filling.
[0052] As can also be seen in the representation in Figure 1, the distributor 1, especially the head piece 5, may be covered by a cover 26 in the non-use position. This cover, in this case, is fixed by locking in the region of the pan wall 17, possibly with axial support on the fixing protrusion 18, as is also preferable.
[0053] In addition, a limiting device 27 is provided for limiting the axial displacement of the top piece 5 together with the piston 8, especially for a distanced position relative to the pan part 9. This limiting position shown is the position of maximum filling of the pump chamber 11.
[0054] The distribution pump 6 is fixed to the reservoir 2 by means of a locking link 30. This is located in a region substantially directly below the fixing protrusion 18 of the pan part 9 which rests on the wall of the reservoir 2.
[0055] Thus, two locking edges 31, 32 are provided. Petition 870260049464, dated 05 / 25 / 2026, page 16 / 60 13 / 19 spaced apart from each other with respect to the longitudinal x-axis on the outer side of the pan wall 17, which project radially outwards through a respective outer surface 33 of the surrounding pan wall 17.
[0056] The outer surface 33 of this pan wall 17 rests against the inner surface 34 of the chamber wall 35 facing it, in a preferred configuration in the locking fastening position.
[0057] The two locking edges 31, 32 are configured the same with respect to a cross-section according to the representation in Figure 2, in the example embodiment shown.
[0058] Thus each locking flange 31, 32 in the fitting direction r of the distributor pump 6 in the reservoir 2, is initially provided with a leg 36 which includes an acute angle α, with an axial parallel y observed in relation to the longitudinal axis x, of about 30 to 45 degrees, which extends upward radially outward, oriented against the fitting direction r.
[0059] This leg 36 transitions, on the end side, into an insertion opening 37, which, in turn, leads to a support surface 38 that enters more or less at a right angle to the longitudinal axis in relation to the longitudinal axis x. The support surface 38 is oriented, correspondingly, against and transversely to the insertion direction r.
[0060] In general, this results in a triangular or wedge-shaped cross-sectional configuration of the locking edge 31, 32 with a rounded angular configuration through the rounding of the introduction 37.
[0061] Observing in the direction of the longitudinal axis x-coordinate, a height a of a locking edge 31, 32 results, which can correspond to approximately 1 / 3 to 2 / 3, for example, about ½ of the thickness of the chamber wall material 35. The height measurement a Petition 870260049464, dated 05 / 25 / 2026, p. 17 / 60 14 / 19 is then considered to be between the root regions of the locking edges 31, 32, where these enter the outer surface 33 of the pan part 9 (compare Figure 2).
[0062] The distance b of the locking edges 31, 32 from each other, observed also in the direction of engagement of the longitudinal axis x, may correspond to approximately 1.5 to 3 times, about 2 times the height of the locking edge.
[0063] The radial extension c observed transversely to the height a, which corresponds, in the locked position, to the entry measurement of the locking edges 31, 32 into the chamber wall 35, may correspond to approximately 0.3 to 0.8 times, or approximately 0.5 times the edge height a.
[0064] The locking edges 31, 32, in the locking position according to Figure 2, are engaged in locking grooves 39 of the chamber wall 35 arranged in a corresponding manner and adapted according to the cross-section. These locking grooves open correspondingly to the inner surface 34 of the chamber wall 35, and, to reinforce the locking position, backstop surfaces 41 are associated with the backstop surfaces 38 of the locking edges 31, 32, aligned in a corresponding manner, overlapping them across the entire surface.
[0065] In the locking position, the locking edges 31 are in a rear engagement position relative to the backstop surfaces 41 of the locking grooves 39, 40.
[0066] As a result of the chamfered configuration of the leg 36 and the adjacent rounded insertion 37, the locking position can be favorably found. Especially the free upper edge of the chamber wall 35, as well as the locking groove 49 provided. Petition 870260049464, dated 05 / 25 / 2026, p. 18 / 60 15 / 19 initially in the direction of engagement r, will extend favorably.
[0067] Removal of the dispensing pump 6 from the locking position against the engagement direction r is prevented by the backing, possibly across the entire surface, of the backing surfaces 38 on the counter-backing surfaces 41.
[0068] Between the cylindrical section 10 of the pan part 9 and a wall of the piston part 42 encompassing this cylindrical section 10 and the replacement device 16, a first internal space 43 is created. In this latter space is received the replacement device 16, preferably in the form of a cylindrical spring.
[0069] The piston part wall 42 is disposed in the piston part 7 by means of an upper backing cover 44, against which the replacement device 16 strikes on the underside.
[0070] To prevent pressure buildup in the internal space 43 during actuation of the top part 5 and, consequently, a reduction in the volume of the pump chamber 11, as well as the volume of the internal space 43, the back cover 44 has an air path 45 that connects the first internal space 43 to the surrounding environment using a second internal space 47 that surrounds it. Correspondingly, regardless of the position of the top part 5 in relation to the distributor pump 6, a usual ambient pressure results in the first internal space 43.
[0071] The second internal space 47 visibly opens into a gap between the top piece 5 and the pan part 9, which allows for constant exchange with ambient air. When the top piece 5 is compressed, as a result of the distributor's action, the first internal space 43 is reduced, and air can then flow into the second internal space 47 and from there, through the aforementioned gap, to the surrounding environment via the air path, specifically the opening 46. As observed, the air path 45, in the example of Petition 870260049464, dated 05 / 25 / 2026, page 19 / 60 16 / 19 implementation represented, is given in the form of a perforation 46 within the closing wall 44 (compare especially Figure 4).
[0072] In addition, improved ventilation and exhaust of the spring chamber located underneath occurs through this opening 46.
[0073] Furthermore, through opening 46, during the assembly of distributor 1, a check can be carried out, for example, a vision check, to verify if the replacement device 16 required for the operation of distributor 1 is inserted. This device is usually visible through opening 46.
