DISCLOSURE OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to the field of dispensing liquids, and more particularly to liquids used in the field of pharmacy, such as eye drops or ear drops. [Prior Art] A conventional liquid dispensing device has a container and a dispensing end piece, the dispensing end piece is mounted on the container, and the dispensing end piece has a support member and a locking member. For example, in document US 2007/0210115, the dispensing end piece includes a support member having a closure member that is movable within the support member between a barrier configuration and a liquid passage configuration. On the distal end of the shutoff element adjacent the liquid release orifice □, the closure element also includes a shape for reducing the flow rate of the liquid. The flow rate reducing shape includes a channel having a spiral shape of a small cross section adapted to direct liquid to cause head loss when a user squeezes the container. The shape is reduced by the flow rate to ensure that the liquid is not dispensed in the spray pattern. SUMMARY OF THE INVENTION The difficulty noticed by the inventors of the present invention is that the shape for reducing the liquid flow rate and the shape for blocking or allowing the liquid to pass are made in the same part. This configuration requires the valve member and the support since this configuration must simultaneously move the valve member relative to the support member to allow liquid to pass therethrough and also to bring the sufficiently close flow guiding shape into cooperation with the support member to obtain a non-leakage-conducting passage. The piece has a fairly accurate size and will not have a flow rate reduction effect if the above method can achieve -5 to 201225948. Unfortunately, it is quite difficult to make parts that require this dimensional accuracy. A particular object of the present invention is to provide a dispensing device that, when dispensing a liquid, ensures a reduction in liquid flow rate while at the same time ensuring satisfactory operation. For this purpose, the present invention particularly provides a liquid dispensing device comprising: a container for storing the liquid to be dispensed; a dispensing end piece mounted to the container, the dispensing end piece having a support member and a liquid dispensing valve comprising an elastomeric material and employing a barrier configuration and a liquid passage configuration by cooperation with the support member; and a rate reduction element comprising a channel for defining a rate reduction channel A liquid flow directing element that is separate from the support and separates one of the parts from the liquid dispensing valve. Therefore, the flow rate reduction function is performed by a third part different from the valve member and the support member, that is, the third part is separated from the valve member and the support member, or before the dispensing device is assembled, The third part is at least separated from the valve member and the support member. By utilizing a separate part for limiting the flow rate of the liquid, the dispensing end pieces are separated from each other by blocking the liquid or allowing the liquid to pass through the means for providing the dispensing means to seal the liquid flow rate. Since the flow rate reduction is performed by a third part that is not located in the sealing area obtained by the cooperation of the valve member and the support member, the sealing function can be provided separately by the flow rate reduction function. Therefore, each function is executed in the best and reliable mode -6- 201225948. Although it is expected that the assembly of the dispensing device will be more complicated because of the extra assembly parts, since the flow rate reduction region is no longer dependent on the shape of the valve member and the support member that provides the sealing action of the dispensing device, the dispensing device is actually The assembly method has been simplified. Therefore, it is easier to modify the length or diameter of the flow reduction shape. Moreover, because the flow rate reduction function is not provided in the sealing area of the dispensing end piece, a shorter sealing area can be made and thereby a smaller dispensing end piece can be made. Since the flow rate reduction function and the sealing function are separate, it is easier to manufacture parts by assuming that the dimensional changes of these parts do not have too much influence on the operation of the dispensing device. This is advantageous because it can cause industrial difficulties when using excessively high precision levels, such as: tools are easily damaged or the mold is easily broken. Furthermore, a particular advantage of one of the present invention is that it is easy to modify the dispensing device depending on the type of liquid to be dispensed. The flow rate reduction channel must exhibit a particular configuration depending on the viscosity of the liquid. For example, for high viscosity liquids, it is possible to use a flow rate reduction channel having a larger diameter. Since the flow rate reducing element is a separate part, in order to modify the dispensing end piece depending on the type of liquid to be dispensed, it is only necessary to modify the shape of the flow rate reducing element without the shape of the valve member and the support member. Any modification is made so that the shape of the valve member and the support member can have a standard shape. In addition, since the flow rate reduction is provided by a separate part, it is possible to simultaneously provide a distribution device having a flow rate reduction function and a distribution device having no flow rate reduction function, and the difference between the two distribution devices is only the flow rate. Reduce the presence or absence of components. 201225948 It should be noted that for these liquids that are used in eye drops that are becoming more and more viscous, it is particularly advantageous to modify the dispensing device depending on the viscosity of the liquid, especially for eye drops that do not contain preservatives. The liquid is more advantageous. The term "flow rate reduction" is intended to reduce the rate of liquid flow by applying a predetermined pressure to the container. The flow rate reduction is preferably achieved by having a section that is smaller than one of the other flow channels and/or having a length greater than one of the other flow channels and/or having one of the laterally extending axes. It is advantageous to utilize the flow rate reducing element to charge one of the spaces in the dispensing device and thus to reduce one of the inactive volumes in the dispensing end piece 'this invalid volume can cause bacterial growth. The dispensing device can also include the following One of the features above: • The support includes a housing 'shell for receiving the flow rate reducing element and cooperating with the flow rate reducing element to define a flow rate reduction passage. It will be appreciated by way of example that the location of the housing is relative to the position of the support member used to provide sealing of the dispensing device so as to be more restrictive for the interaction between flow rate limiting and sealing action. The containment housing is preferably substantially cylindrical in shape, and the volume of the cavity defined by the housing is substantially complementary to the volume of the flow rate reducing element. • The flow rate reducing element is substantially cylindrical. The liquid flow guiding shape is formed around the outside of the flow rate reducing element and includes a spiral groove. The spiral shape of this channel provides a lateral flow direction that is non-parallel to the direction of liquid injection '-8 - .201225948 while also providing a relatively long channel length 'obtained by a helical groove system occupying a minimum amount of space in the dispensing device Water head loss. • The flow rate reducing element is substantially cylindrical in shape, and the liquid flow guiding shape is formed around the flow rate reducing element and includes a groove for defining a plurality of corners. These corners act to define a path that has a sharp change in flow direction, thereby disturbing fluid flow and causing higher head loss. The flow rate reducing element is substantially cylindrical in shape, and the liquid flow guiding shape is formed around the flow rate reducing element and includes a linear groove. The straight groove is preferably substantially parallel to the cylindrical axis of the flow rate reducing element. Because of the geometry of the grooves, particularly because of the cross-sectional dimension of the grooves, fluid flow is disturbed and causes head loss sufficient to reduce flow rate. The flow rate reducing element is substantially cylindrical, and the liquid flow guiding shape is formed around the flow rate reducing element and includes a network of a plurality of grooves having at least one node, the grooves intersecting at least one node. The flow system that flows in the same groove does not intersect at the node. This creates a spoiler area that can cause a high head loss. • The support member includes a sealing member having a bearing surface for supporting a liquid dispensing valve to block liquid passage in a blocking configuration. The sealing member is substantially cylindrical and the bearing surface is located at a cylindrical shape. end. The sealing member is substantially in the form of a plug which is closed by a plug for one of the corresponding sealing members formed in one of the liquid dispensing valves. • The liquid dispensing valve includes a substantially cylindrical member that covers the cylindrical shape and cooperates with the cylindrical shape to define a liquid passageway disposed downstream of the flow rate reducing passage.

The snap member 54 is attached to one of the webs 56 in the form of a substantially disc and a substantially cylindrical central member 58 projects from the web 56. The web 56 also includes a carrier 57 for use with the spring 17. The central member 58 defines a cavity having a substantially cylindrical shape that is complementary to the plug 38. Plug 38 and substantially cylindrical member 58 are coaxial and collectively define a second liquid passageway 36. The second liquid passageway 36 leads to one of the outlet passages 60 formed in the distal end of the liquid dispensing valve 16, and the outlet passageway 60 leads in turn to a shape 62 forming a droplet. The cover 18 has an annular fastening member 64 and another annular fastening member 66. The annular fastening member 64 is for fixing to the support member 14, and the annular fastening member 66 is coupled to the annular fastening member. 64 coaxial to define a groove 68 'annular wall 52 is received in the groove 68. The cover 18 also includes a carrier 70 for use with the spring 17, extending around its inner periphery by an annular wall 72, and the substantially cylindrical member 58 is passed through the annular wall 72 which acts to distribute the valve 16 The substantially cylindrical member 58 is placed in the center. The flow rate reducing element 20 includes a liquid flow directing shape 74 that is defined in cooperation with the housing 30 to define a flow rate reducing passage 76. As shown in the examples in Figures 3a through 3f, the flow rate reducing element 20 can have a variety of shapes. The flow rate reducing member 20 is substantially cylindrical, and the liquid flow guiding shape 74 is formed around the flow rate reducing member 2, and the liquid guiding shape 74 forms a peripheral concave portion. -13- 201225948 In the embodiment of Figures 3a, 3b, the liquid flow guiding shape 74 is wound around one of the helical flow grooves 74a, 74b of the cylindrical flow rate reducing element 2, and if the viscosity of the liquid is not high The spiral grooves 74a, 74b are surrounded by the plurality of turns around the cylindrical flow rate reducing element. The section of the spiral 74a is larger than the section of the spiral groove 74b and the spiral groove is more suitable than the spiral groove 74b. The higher viscosity liquid. The flow rate reducing element 20 in Figures 3c, 3d has other types of grooves 74c, 74d which are not surrounded by a circle in the cylindrical portion of the flow rate reducing element', and these The grooves 74c, 74d define a complex, here a right angle portion, having the effect of reducing the liquid flowing therethrough. . Optionally, the flow rate reducing element 20 includes a groove in the portion of its surrounding wall that is similar to the grooves 74c, 74d and that increases the liquid flow rate. The flow rate reducing element 20 of Fig. 3e has a linear groove 74e which is substantially parallel to the cylindrical axis of the cylindrical flow rate reducing element 20. In a variant, the flow rate reducing element 20 has a plurality 74e, and the grooves 74e are distributed over the entire wall of the flow rate reducing element 20. In another variation, the single/complex groove 74e is inclined with respect to the cylindrical axis of the cylindrical portion of the lowering member 20. The flow rate reduction element 20 of Figure 3f includes a network having a number of nodes 74i number of grooves 74f-h that intersect at the node. The network has a plurality of upstream grooves 74f upstream of the node 74i. g and at least one downstream trench 74h downstream of node 74i. In a variant, the groove of the preferred groove 74a is determined by the ring. The angle of the pulse is 20 degrees. The other number of grooves is the sum of the circumferential flow rate of the straight portion of the groove 74i. The number of upstream grooves 74 f-g located in the network -14- 201225948 is greater than 2, the number of downstream grooves 7 4h is greater than 1 and the number of nodes 74i is greater than 1. The operation of the dispensing device 10 of Fig. 1 will be explained below. At rest, that is, when the user has not squeezed the container 12, the liquid dispensing valve 16 is in its blocking configuration, that is, because the liquid dispensing valve 16 is permanently snapped onto the support member 14, so the liquid The dispensing valve 16 abuts the bearing surface 40' to apply an elastic stress to the liquid dispensing valve 16 under the pressure transmitted by the spring 17. When a user squeezes the container 12, pressure is applied to the fluid, and the fluid flows along the only passage through which it can flow (the hydrophobic filter 22 prevents liquid from flowing out), i.e., flows through the flow rate reducing passage 76. As the fluid passes along the flow rate reduction passage 76, the fluid flow rate is reduced by the head loss effect. This fluid then flows along the first liquid passage 32 and then flows into the cavity 34 and flows along the second liquid passage 36. Under pressure, the fluid causes the diaphragm 16 to rise and thus become its liquid passage configuration such that liquid can flow between the diaphragm 16 and the bearing surface 40 into the outlet passage 60 and into the cavity 61, thus presenting Drip type. It should be noted that since the flow rate reducing member 20 is a separate component, the shape of the flow rate reducing member 20 can be changed depending on the liquid in the container. Therefore, the casing 30 is adapted to accommodate flow rate reducing members 20 of different shapes as shown in Figs. 3a to 3f. Thus, a group comprising a plurality of dispensing end pieces having the same liquid dispensing valve 16, the same support 14 and the same cover 18 can be manufactured, but exhibiting different flow rate reducing elements 20. -15- 201225948 The dispensing end piece 10 is of a configuration which may have a configuration different from that shown in Fig. 1, for example, as shown in Fig. 2. The distribution end piece of Fig. 2 has a function similar to that of the distribution terminal of Fig. 1 except that it does not have the air passage 42. In the present embodiment, the container 12 is preferably a container that is deformable in a non-elastic manner, so that no air is introduced into the container 12 after the container 12 is squeezed by the user to compensate for the release. Suction. Thus, in the present embodiment, the housing 30 is located at the center of the support member 14 and the flow rate reducing member 20 can have a larger diameter. It should be noted that the present invention is not limited to the above embodiments.
