Description

TECHNICAL FIELD

[0002] Document WO2009139015A1 discloses a fluid product dispenser comprising a dispensing head and a threaded cap capable of axial relative movement with respect to each other, the dispensing head comprising a metering chamber obtained inside the dispensing head and a dispensing nozzle allowing the outflow of the fluid product, the metering chamber having a containment volume which can vary between a maximum volume configuration and a minimum volume configuration when the metering chamber is isolated; the fluid product dispenser further comprises a deformable diaphragm (also known as a bladder pump) fastened to the threaded cap and a deformable disc-shaped body (also known as a sealing sheet) fastened to the dispensing head and defining the metering chamber together with the deformable diaphragm.

[0003] In use, pressing the dispensing head allows the dispensing head to slide axially with respect to the threaded cap, then the volume of the metering chamber defined by the deformable diaphragm and the deformable disc-shaped body is reduced, the fluid stored therein is pressed out and flows out through the dispensing nozzle; after releasing the pressing force, the metering chamber returns to the maximum volume and generates a negative pressure, under the action of which the fluid in the fluid product container is sucked into the metering chamber.

[0004] Although the fluid product dispenser can bring a better experience in use, it is inconvenient to disassemble, clean and reassemble. When disassembling, the deformable diaphragm fixed on the threaded cap and the deformable disc-shaped body fixed on the dispensing head can be cleaned only after the threaded cap is separated from the dispensing head.

[0005] However, since the peripheral band of the deformable diaphragm has a certain assembly relationship with the circumferential inner wall of the dispensing head, the disassembly and reassembly work between the threaded cap and the dispensing head will be hindered, and frequent disassembly and assembly will also affect the sealing effect between the peripheral band of the deformable diaphragm and the circumferential inner wall of the dispensing head.

[0034] Embodiment

[0035] A cleanable fluid product dispenser, such as a pump, comprises an actuating cap 1 and a pump body 2, which are detachably fixedly connected to each other, for example by screwing, and when the actuating cap 1 and the pump body 2 are separated from each other, the entire fluid passage of the dispenser is exposed to facilitate cleaning, and after cleaning is completed, the actuating cap 1 and the pump body 2 are connected again, and the dispenser can be reused. Figures 1-5

[0036] The pump body 2 comprises an outer cap 3, a threaded cap 4 and a bladder pump 5, and the side of the actuating cap 1 facing the pump body 2 is fixed with a sealing sheet 6.

[0037] ​The inner wall of the lower end of the screw cap 4 is internally threaded, so that the screw cap 4 can be connected to the outer thread on the container by screwing. The screw cap 4 is coaxially provided with a fluid storage chamber 7 in the center thereof, which is in the form of a cylindrical barrel, and is connected to the screw cap 4 by an annular wall 8. It will be appreciated that the screw cap 4, the fluid storage chamber 7 and the annular wall 8 are usually integrally formed. A sealing structure, such as a sealing gasket or a sealing ring, is usually provided between the annular wall 8 and the fluid product container.

[0038] The upper end of the fluid storage chamber 7 is in the form of an open structure, so that the fluid product can flow out of the fluid storage chamber 7. The lower end of the fluid storage chamber 7 has a medium inlet, which is provided with a valve seat for cooperating with a valve 9. The valve 9 is used to control whether the fluid product can flow from the fluid product container into the fluid storage chamber 7 through the medium inlet. The valve 9 includes a ball 91 positioned on the valve seat, which can be in the form of a spherical surface or a conical surface. In addition, a retainer 92 is provided on the inner wall of the fluid storage chamber 7 for controlling the floating range of the ball 91.

[0039] In addition, the lower end of the fluid storage chamber 7 is integrally formed with a tubular wall 10, which is in communication with the fluid storage chamber 7. The tubular wall 10 is used to connect a suction pipe 11, which is used to extend into the fluid product container.

[0040] At the same time, the bladder pump 5 is provided with an opening 51 for communicating with the fluid storage chamber 7, as shown in Figure 6 .

[0041] The outer cap 3 is in the form of a cylindrical barrel with both ends open. The upper end of the outer cap 3 is externally threaded. The actuating cap 1 is in the form of a cylindrical barrel with the upper end closed and the lower end open. The inner wall of the lower end of the actuating cap 1 is internally threaded, so that the outer cap 3 and the actuating cap 1 are connected to each other by screwing.

[0042] In addition, a sealing structure, such as a sealing ring 101, is formed on the actuating cap 1, as shown in Figure 7 . A corresponding sealing ring groove 301 is provided on the outer cap 3, as shown in Figure 8 .

[0043] The outer cap 3 can also axially slide relative to the screw cap 4. For example, the lower end of the outer cap 3 is sleeved on the outside of the screw cap 4, and there is a gap between the two, so that the two can move relative to each other in the axial direction.

[0044] The interior space surrounded by the actuating cap 1 and the pump body 2 is provided with a metering chamber 12, which has a variable holding volume, and the holding volume of the metering chamber 12 can be changed between a maximum volume and a minimum volume. When the metering chamber 12 is in the maximum volume state, it is isolated from the outside. The metering chamber 12 is jointly defined by a bladder pump 5 made of a deformable elastic material and a sealing sheet 6, and the bladder pump 5 is fixedly connected to the threaded cap 4. When the outer cap 3 is axially slid on the threaded cap 4, the outer cap 3 can drive the sealing sheet 6 to move towards the bladder pump 5, so that the holding volume of the metering chamber 12 changes. Of course, the bladder pump 5 can also be fixed to the outer cap 3. In this way, when the outer cap 3 is axially slid on the threaded cap 4, the outer cap 3 can drive the sealing sheet 6 and the bladder pump 5 to move together, and when the metering chamber 12 formed by the two is extruded, the holding volume of the metering chamber 12 changes. In addition, the bladder pump 5 can also be fixedly connected to both the outer cap 3 and the threaded cap 4. In this way, when the outer cap 3 is axially slid on the threaded cap 4, the holding volume of the metering chamber 12 formed by the sealing sheet 6 and the bladder pump 5 changes.

[0045] It is easy to understand that the change of the holding volume of the metering chamber 12 is caused by the axial movement of the actuating cap 1 (and the outer cap 3 fixed thereto) relative to the threaded cap 4, that is, the actuating cap 1 can be moved between a first position and a second position. When the actuating cap 1 is in the first position, the bladder pump 5 is away from the sealing sheet 6, and the metering chamber 12 is in the maximum volume state. When the actuating cap 1 is in the second position, the bladder pump 5 is close to the sealing sheet 6, and the metering chamber 12 is in the minimum volume state.

[0046] Among them, the actuating cap 1 is also provided with a nozzle 13 allowing the fluid product to flow out of the metering chamber 12.

[0047] Among them, the outer edge of the bladder pump 5 is in contact with the inner wall of the outer cap 3, so as to realize sealing. In addition, the outer edge of the bladder pump 5 is provided with a clamping protrusion 52 at the upper end, which is clamped at the upper end of the outer cap 3, so as to prevent the bladder pump 5 from sliding off the outer cap 3 and to strengthen the sealing effect, as shown in Figure 6 .

[0048] In addition, as shown in Figure 9 , the side of the sealing sheet 6 towards the bladder pump 5 is also formed with an extension piece 14 extending into the interior of the bladder pump 5, the extension piece 14 is in the shape of a long strip and is substantially parallel to the sliding direction of the actuating cap 1, the extension piece 14 is opposite to the opening 51 formed on the bladder pump 5, and the end of the extension piece 14 away from the actuating cap 1 is formed with a closing piece 15, which is used to close the communication state between the bladder pump 5 and the fluid storage chamber 7 when the metering chamber 12 is in the maximum volume state (that is, when the actuating cap 1 is in the first position), that is, the closing piece 15 can just close the opening 51 at this position, on the contrary, when the actuating cap 1 is not in the first position, the closing piece 15 no longer closes the opening 51.

[0049] In this embodiment, the closure 15 is configured as a sealing flange shaped on the extension 14 and in a ring-like configuration, and correspondingly, the opening 51 is provided with a sealing flange ring used in cooperation with the sealing flange. It is easy to understand that, since the bladder pump 5 and the sealing sheet 6 are both made of deformable elastic material, a sealing contact surface can be formed between the sealing flange and the sealing flange ring by mutual extrusion therebetween.

[0050] In addition, as shown in Figure 7 The inner top wall of the actuating cover 1 is integrally provided with a support column 16 extending towards the inside of the bladder pump 5, and the side of the extension 14 towards the actuating cover 1 is provided with a groove adapted to the support column 16, the support column 16 is inserted into the groove, and the length of the support column 16 is configured to be substantially equal to the depth of the groove, and the support column 16 is fixed in the groove in the form of threading or buckling. In this way, not only can the sealing sheet 6 be conveniently fixed on the actuating cover 1, but also the structural strength of the extension 14 can be enhanced by the support column 16 to prevent deformation or bending of the extension 14 during use, thereby ensuring the sealing effect of the closure 15.

[0051] The use process of the washable fluid product dispenser disclosed in the embodiment of the present application is as follows:

[0052] In use, the threaded cover 4 is connected to the fluid product container, and then the actuating cover 1 is pressed, on the one hand, the metering cavity 12 is deformed under pressure to reduce its containing volume, and on the other hand, the extension 14 extends into the fluid storage cavity 7, so that the closure 15 no longer hinders the communication state between the bladder pump 5 and the fluid storage cavity 7, but due to the presence of the valve 9, the fluid product cannot flow through the valve 9 to the fluid product container, so the fluid product can only finally flow out of the nozzle 13.

[0053] When the actuating cover 1 is released, the metering cavity 12 returns to its original state, so that a negative pressure is formed in the metering cavity 12, and the fluid storage cavity 7 connected to the metering cavity 12 also has a negative pressure state, under the action of the negative pressure, the valve 9 is opened, and the fluid product in the fluid product container is sucked into the fluid storage cavity 7 and continues to enter the metering cavity 12 to supplement the consumption of the fluid product therein, until the metering cavity 12 returns to the maximum volume state, at this time, the closure 15 re-seals the communication state between the bladder pump 5 and the fluid storage cavity 7, at this time, the metering cavity 12 and the fluid storage cavity 7 are both in a closed state, and the fluid products stored in the two will not overflow, and after the actuating cover 1 is pressed again, the above process can be repeated.

[0054] Compared with the prior art, the washable fluid product dispenser disclosed by the application only needs to separate the screw cap 4 from the container loaded with the fluid product, and then detach the actuating cap 1 from the outer cap 3, so that the capsule pump 5, the sealing sheet 6 and the flow channel can be cleaned respectively, and after the cleaning is completed, the actuating cap 1 and the outer cap 3 are reconnected.

[0055] The embodiments of the application are described in detail above with reference to the drawings, but the application is not limited to the described embodiments. For those skilled in the art, various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the application, and still fall within the protection scope of the application.
