[0002] In the field of fluid product dispensing technology, the fluid product stored in the bottle can be dispensed for use under the operation of a dispensing component. In order to enable the fluid product to be dispensed continuously, the bottle needs to maintain its internal air pressure close to the atmospheric pressure, so the bottle is usually designed with an air intake function.

[0003] However, some fluid products are easily oxidized, so it is necessary to prevent air from directly entering the bottle during use. However, in order to ensure that the dispensing component can continue to work normally, the bottle body needs to be additionally designed so that the pressure in the bottle body will not decrease due to the reduction of fluid products, such as making the volume space of the bottle body have the function of being able to be continuously reduced. However, the bottle body used to store fluid products is usually a consumable part. If its structural design is more complicated, the cost of replacing the bottle body will increase significantly. Therefore, a new fluid product dispenser is needed, which ensures that the dispensing component can be used normally and prevents the fluid product in the bottle body from being oxidized while keeping its bottle body structure simple and easy to produce.

[0026] Example 1

[0027] A fluid product dispenser comprises a dispensing component for dispensing the fluid product from a bottle body 1 , the dispensing component is used in conjunction with the bottle body 1 for storing the fluid product, and in this embodiment, the dispensing component is configured as a press pump 2 .

[0028] The fluid product dispenser also includes an adsorption device 3, which has an air inlet channel connected to the bottle body 1, and an adsorbent 4 and a breathable structure 5 are arranged in sequence along the air inlet direction in the air inlet channel, wherein the adsorbent 4 can be iron powder or bagged iron powder compressed into a ring shape, and the breathable structure 5 is, for example, a breathable membrane, which only allows gas to pass through and isolates materials including fluid products, water, etc. from passing through, thereby preventing the fluid product in the bottle body 1 from leaking. The adsorbent 4 is used to remove specific components in the air entering the bottle body 1, such as oxygen, carbon dioxide or other components. It is easy to understand that the breathable structure 5 can also be coated on the outside of the adsorbent 4.

[0029] The distribution component is also used to close or release the air intake passage by changing its use state. When the distribution component is a press pump 2, the air intake passage is released and air can be taken in after the press pump 2 is pressed; the air intake passage is closed and air cannot be taken in after the press pump 2 is reset.

[0030] The adsorption device 3 includes a fixing cover 31 and an adsorption cover 32 .

[0031] The fixed cover 31 is connected to the outside of the bottle mouth of the bottle body 1 by means of threads or snaps, and a central channel 33 connected to the bottle mouth of the bottle body 1 is formed at the center of the top wall of the fixed cover 31. The adsorption cover 32 is connected to the outside of the fixed cover 31 by means of threads or snaps, and an annular channel 34 for arranging the adsorbent 4 and the air-permeable structure 5 is formed between the side wall of the central channel 33 and the side wall of the adsorption cover 32, and the annular channel 34 is used as an air intake channel, and there is a gap for air intake between the top of the central channel 33 and the top wall of the adsorption cover 32, so that the annular channel 34 is connected to the central channel 33. Of course, it is also possible to achieve communication between the top of the central channel 33 and the top wall of the adsorption cover 32 by opening a through hole at the upper end of the central channel 33.

[0032] The top wall of the adsorption cover 32 is provided with a mounting hole for the pressing pump 2 to pass through, so that the pressing pump 2 can extend into the central channel 33 after passing through the top wall of the adsorption cover 32, and then extend into the bottle body 1 through the central channel 33. In this embodiment, the pressing pump 2 forms a sealed and fixed connection with the mounting hole on the adsorption cover 32, and the inner diameter of the central channel 33 is larger than the diameter of the pressing pump 2, so that there is a gap between the two for air to pass through.

[0033] The press pump 2 in this embodiment is a well-known technology, which generally includes a pump housing 21, a pump cover 22, a pump core 23, a suction pipe 24, a dispensing pipe 25 and a spring. When the press pump 2 is in use, its pump housing 21 is in a fixed state, and the pump core 23 can reciprocate in the pump housing 21 under the action of the pressing force and the spring, and during the reciprocating movement, the fluid product is sucked into the pump housing 21 through the suction pipe 24, and then the fluid product continues to flow through the pump core 23 to the dispensing pipe 25, so that the fluid product is provided to the outside through the dispensing pipe 25.

[0034] This embodiment utilizes the movement of the pump core 22 to open and close the air intake passage.

[0035] Specifically, the top of the pump housing 21 is open, and the pump cover 22 is fixed to the top of the pump housing 21. The pump cover 22 is sealed and fixed in the mounting hole opened on the top wall of the adsorption cover 32 in a snap-fit ​​manner. The pump core 23 is axially movably arranged in the pump housing 21, the suction pipe 24 is fixed to the bottom end of the pump housing 21 and extends into the bottle body 1, the dispensing pipe 25 is connected to the pump core 23, and the pump cover 22 is also provided with a through-hole for the dispensing pipe 25 to pass through. The diameter of the through-hole is slightly larger than the diameter of the dispensing pipe 25, so that air can enter the interior of the pump housing 21 through the gap between the two.

[0036] In addition, an air inlet 26 is provided on the side wall of the pump housing 21, and the air inlet 26 is used to allow the air in the pump housing 21 to enter the gap between the central channel 33 and the pressing pump 2, and then enter the annular channel 34, that is, through the gap between the top of the central channel 33 and the top wall of the adsorption cover 32. The air entering the annular channel 34 will return to the central channel 33 again, that is, a through hole 35 is provided at the lower end of the central channel 33, so that the deoxygenated air can provide air inhalation support to the bottle mouth of the bottle body 1 through the central channel 33.

[0037] At the same time, a sealing flange 36 is formed at approximately the middle position of the inner wall of the central channel 33, and the sealing flange 36 forms a sealing effect with the outer wall of the pump housing 21, thereby dividing the gap space formed between the central channel 33 and the pressing pump 2 into two independent parts, the upper part of which is used to guide the air entering the pump housing 21 into the annular space 34, and the air inlet hole 26 on the pump housing 21 is connected to the upper part, and the lower part is used to guide the deoxygenated air in the annular space 34 back to the central channel 33, and then enter the bottle mouth of the bottle body 1.

[0038] In other preferred embodiments, the central channel 33 can also be configured as a stepped structure with a larger upper diameter and a smaller lower diameter, and the upper diameter of the central channel 33 can be matched with the diameter of the pump housing 21, so that the pump housing 21 is sealed and fixed in the upper stepped hole of the central channel 33. At the same time, a through hole connected to the air inlet hole 26 on the pump housing 21 can be opened at the upper end of the central channel 33, so that the air entering the pump housing 21 can enter the annular channel 34 through the air inlet hole 26 thereon and the through hole opened at the upper end of the central channel 33.

[0039] A separator ring 37 is formed on the outer wall of the central channel 33, and the outer edge of the separator ring 37 is in sealing contact with the inner wall of the adsorption cover 32. The separator ring 37 separates the annular channel 34 into two independent upper and lower parts, and the breathable structure 5 and the adsorbent 4 are both arranged on the separator ring 37. The separator ring 37 is provided with a breathable hole 38 facing the breathable structure 5. At the same time, the separator ring 37 is provided with a groove adapted to the breathable structure 5 to facilitate the installation of the breathable structure 5 through the groove.

[0040] The device further comprises an actuating cover 6 , which is movably connected to the adsorption cover 32 , and the actuating cover 6 also has a nozzle 7 connected to the dispensing tube 25 of the pressing pump 2 .

[0041] It is easy to understand that the fixed cover 31 can also be configured as a transparent material to facilitate observation of the adsorbent 4. At the same time, the adsorbent 4 can also have a color indication function to indicate the usage of the adsorbent 4. For example, the anaerobic indicator has two colors, aerobic and anaerobic. This material is added to the adsorbent 4 (such as an iron powder block) to observe the color change.

[0042] The use process of the fluid product dispenser provided by the embodiment of the present invention is as follows:

[0043] When in use, a pressing force is applied to the pressing pump 2 through the actuating cover 6. After the pressing pump 2 changes its state from being pressed to being reset, it pumps the fluid product out of the bottle 1 and sprays it out through the nozzle 7 of the actuating cover 6. During the state change of the pressing pump 2, when the pressing pump 2 is pressed, the pump core 23 will drop and move away from the air inlet 26. At this time, air can flow along the gap between the actuating cover 6 and the adsorption cover 32, the gap between the pump cover 22 and the dispensing pipe 25, the pump housing 21, the air inlet 26 on the pump housing 21, and the gap formed between the central channel 33 and the pump housing 21. The air inlet 26 on the side wall of the pump housing 21 is sealed with the air inlet 26 sealed thereon by the adsorbent 4. The air inlet 26 on the side wall of the pump housing 21 is sealed with the air inlet 26 sealed thereon by the adsorbent 4. The air inlet 26 on the side wall of the pump housing 21 is sealed with the air inlet 26 sealed thereon by the adsorbent 4.

[0044] Example 2

[0045] like Figure 2-3 As shown, in this embodiment, the dispensing member is configured as a dropper 8, which generally includes a main body and a straw portion connected to the main body. By repeatedly squeezing the main body, the fluid product can be sucked into the main body through the straw portion.

[0046] This embodiment modifies the adsorption device 3 in the embodiment 1, specifically including:

[0047] The central channel 33 is arranged in reverse to form a bearing groove 39, and the bearing groove 39 is extended from the bottle mouth of the bottle body 1 into the bottle body 1, and a certain gap, i.e., an air intake gap, is provided between the bearing groove 39 and the bottle mouth; in addition, a one-way structure, such as a one-way valve, is provided at the bottom end of the bearing groove 39, so that the fluid product can only flow out from the inside of the bottle body 1 and enter the bearing groove 39, and the air is blocked from entering the bottle body 1 from the bearing groove 39; in order to facilitate the dispensing of the fluid product, a straw extending into the bottle body 1 is also connected to the lower end of the bearing groove 39;

[0048] Since the bearing groove 39 is arranged in reverse, the annular channel 34 will also disappear. Instead, a groove 310 for arranging the adsorbent 4 and the air-permeable structure 5 is formed on the fixed cover 21. The groove 310 is arranged outside the bearing groove 39, and the groove 310 is closed by the adsorption cover 32, so as to form an air intake channel; in addition, the groove 310 is also connected to the air intake gap formed between the bearing groove 39 and the bottle mouth through the first air hole 311 opened on the fixed cover 31;

[0049] The adsorption cover 32 is provided with a second air hole 312 for connecting to the above-mentioned air inlet passage (i.e., the closed groove 310). When the dropper 8 is not in use, its main body forms a seal on the top surface of the adsorption cover 32, thereby closing the second air hole 312 and blocking the air inlet passage. Usually, a circle of enclosure structure is formed on the adsorption cover 32 to facilitate the stable placement of the dropper 8.

[0050] When the dropper 8 is not in use, its main body (with a shell) is placed on the adsorption cover 32 and closes the second air hole 312 and the mounting hole opened in the adsorption cover 32 , and its straw portion extends into the bearing groove 39 after passing through the mounting hole on the adsorption cover 32 .

[0051] When the dropper 8 absorbs the fluid product, the fluid product can be sucked into the main body through the straw part by repeatedly squeezing the main body; when the dropper 8 absorbs enough fluid product and is removed, the outside air will enter the air inlet channel through the second air hole 312 opened in the adsorption cover 32, and after passing through the adsorbent 4 and the breathable structure 5, the air enters the air inlet gap formed between the bearing groove 39 and the bottle mouth through the first air hole 311, and then enters the bottle body 1.

[0052] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
