Description
A fluid product dispenser Technical Field
[0001] This invention relates to the field of fluid distribution technology, and in particular to a fluid product dispenser. Background Technology
[0002] In the field of fluid product dispensing technology, the fluid products stored in the bottle can be dispensed for use under the operation of the dispensing device. In order to ensure that the fluid products can be dispensed continuously, the bottle needs to maintain its internal air pressure close to atmospheric pressure. Therefore, the bottle is usually designed with an air intake function.
[0003] However, some fluid products are prone to oxidation, so it's crucial to prevent direct air ingress into the bottle. To ensure continuous proper functioning of the dispenser, additional design modifications to the bottle are necessary to prevent pressure loss as the fluid volume decreases. For example, the bottle's volume could be progressively reduced. However, bottles used to store fluid products are typically consumables; complex designs significantly increase replacement costs. Therefore, a new fluid dispenser is needed that maintains a simple and easily manufactured bottle structure, ensures proper functioning of the dispenser, and prevents oxidation of the fluid within the bottle. Summary of the Invention
[0004] In view of the problem that existing fluid product dispensers require complex bottle structure designs to prevent the fluid products from being oxidized, the present invention aims to provide a fluid product dispenser that at least partially solves the above-mentioned problem.
[0005] To achieve the above objectives, the technical solution of the present invention is as follows:
[0006] A fluid product dispenser includes a dispensing element for dispensing a fluid product from a bottle and an adsorption device, the adsorption device having an air inlet channel in which an adsorbent and a permeable structure are disposed; the dispensing element is also used to close or open the air inlet channel by changing its usage state.
[0007] In some preferred embodiments, the dispensing component is a push-button pump, which includes a pump housing and a pump core movably arranged in the pump housing; the side wall of the pump housing is provided with an air inlet hole for communicating with the air inlet channel, so that the air inlet channel can be inhaled through the pump housing and the air inlet hole thereon; the pump core changes its position within the pump housing to change its blocking state of the air inlet hole, thereby closing or opening the air inlet channel.
[0008] In some preferred embodiments, the adsorption device further has a central channel for mounting the press pump, the central channel connecting the pump housing to the upstream side of the air inlet channel and connecting the bottle body to the downstream side of the air inlet channel.
[0009] In some preferred embodiments, the adsorption device includes a fixed cap and an adsorption cap; the fixed cap is connected to the outside of the bottle opening of the bottle body, and the adsorption cap is connected to the outside of the fixed cap; the central channel is formed on the fixed cap, the air inlet channel is formed between the side wall of the central channel and the side wall of the adsorption cap, and an installation hole is provided on the top wall of the adsorption cap, through which the press pump extends into the central channel.
[0010] In some preferred embodiments, there is a gap between the press pump and the central channel, and the press pump forms a sealed connection at the mounting hole and at approximately the middle of the central channel, with the air inlet on the pump housing located between the two sealed connections; both the upper and lower ends of the central channel are connected to the air inlet channel.
[0011] In some preferred embodiments, a partition ring is formed on the outer wall of the central channel, and the partition ring forms a seal with the inner wall of the adsorption cover; the ventilated structure and the adsorbent are both arranged on the partition ring, and the partition ring has vent holes facing the ventilated structure.
[0012] In some preferred embodiments, the dispensing component is a dropper, which closes the air intake channel when placed on the adsorption device, and opens the air intake channel when the dropper is moved away from the adsorption device.
[0013] In some preferred embodiments, the adsorption device is further provided with a support groove for supporting the dropper, the support groove extending into the bottle body through the bottle mouth, and there is an air inlet gap between the support groove and the bottle mouth.
[0014] In some preferred embodiments, the adsorption device includes a fixed cap and an adsorption cap; the fixed cap is connected to the outside of the bottle opening, and the adsorption cap is connected to the outside of the fixed cap.
[0015] The bearing groove is formed on the fixed cover, and the adsorption cover has an installation hole so that the dropper can be inserted into the bearing groove through the installation hole.
[0016] In some preferred embodiments, the air inlet channel is formed between the fixed cap and the adsorption cap, and the fixed cap has a first air hole that connects the air inlet channel and the bottle opening, and the adsorption cap has a second air hole that connects to the air inlet channel. The dropper is arranged on the adsorption device and also closes the second air hole.
[0017] The beneficial effects of the present invention by adopting the above technical solution are as follows: The present invention, through the setting of the adsorption device, allows specific components, such as oxygen, to be removed from the air before it enters the bottle.

[0026] Example 1
[0027] A fluid product dispenser includes a dispensing element for dispensing fluid product from a bottle 1, the dispensing element cooperating with the bottle 1 for storing fluid product, and in this embodiment the dispensing element 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. An adsorbent 4 and a permeable structure 5 are arranged sequentially along the air inlet direction in the air inlet channel. The adsorbent 4 can be compressed into annular form or bagged iron powder. The permeable structure 5 is, for example, a permeable membrane that allows only gas to pass through while preventing the passage of materials including fluid products and water, thereby preventing leakage of the fluid product inside the bottle body 1. The adsorbent 4 is used to remove specific components, such as oxygen, carbon dioxide, or other components, from the air entering the bottle body 1. It is easily understood that the permeable structure 5 can also cover the outside of the adsorbent 4.
[0029] The component is also used to close or open the air intake passage by changing its usage state. When the component is a press pump 2, the following occurs: after the press pump 2 is pressed, the air intake passage is opened and air can enter; after the press pump 2 is reset, the air intake passage is closed and air cannot enter.
[0030] The adsorption device 3 includes a fixed cover 31 and an adsorption cover 32.
[0031] The fixing cap 31 is connected to the outside of the bottle mouth of the bottle body 1 by means of threads or snaps. At the same time, a central channel 33 is formed at the center of the top wall of the fixing cap 31, which is connected to the bottle mouth of the bottle body 1. The adsorption cap 32 is connected to the outside of the fixing cap 31 by means of threads or snaps. 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 cap 32. The annular channel 34 is used as an air inlet channel. There is a gap between the top of the central channel 33 and the top wall of the adsorption cap 32 for air inlet, so that the annular channel 34 is connected to the central channel 33. Alternatively, if the top of the central channel 33 is sealed to the top wall of the adsorption cap 32, the connection between the central channel 33 and the annular channel 34 can be achieved by opening a through hole at the upper end of the central channel 33.
[0032] The top wall of the adsorption cap 32 has a mounting hole for the press pump 2 to pass through, so that the press pump 2 can extend into the central channel 33 after passing through the top wall of the adsorption cap 32, and then into the bottle body 1 through the central channel 33. In this embodiment, the press pump 2 and the mounting hole on the adsorption cap 32 form a sealed and fixed connection, and the inner diameter of the central channel 33 is larger than the diameter of the press pump 2, so that there is a gap between them for air to pass through.
[0033] The push pump 2 in this embodiment is a known technology, which typically includes a pump housing 21, a pump cover 22, a pump core 23, a suction pipe 24, a discharge pipe 25, and a spring. When the push pump 2 is in use, its pump housing 21 is in a fixed state, and the pump core 23 can reciprocate within the pump housing 21 under the action of the pressing force and the spring. During the reciprocating motion, the fluid product is drawn 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 discharge pipe 25, thereby providing the fluid product to the outside through the discharge 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. At the same time, the pump cover 22 is sealed and fixed in the mounting hole opened in the top wall of the adsorption cover 32 by a snap-fit method. The pump core 23 is axially movably arranged inside 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, and the dispensing pipe 25 is connected to the pump core 23. The pump cover 22 also has 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. This air inlet 26 allows air inside the pump housing 21 to enter the gap between the central channel 33 and the press pump 2, and then enter the annular channel 34, which is achieved through the gap between the top of the central channel 33 and the top wall of the adsorption cap 32. The air entering the annular channel 34 will return to the central channel 33. 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 intake support to the bottle opening of the bottle body 1 through the central channel 33.
[0037] Meanwhile, a sealing flange 36 is formed on the inner wall of the central channel 33 at approximately the middle position. 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 press pump 2 into two independent parts. The upper part is used to guide the air entering the pump housing 21 into the annular space 34, and the air inlet 26 on the pump housing 21 is connected to the upper part. The lower part is used to guide the deoxygenated air in the annular space 34 back to the central channel 33, and then into the bottle mouth of the bottle body 1.
[0038] In other preferred embodiments, the central channel 33 can 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 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 26 and the through hole opened at the upper end of the central channel 33.
[0039] A partition ring 37 is formed on the outer wall of the central channel 33. The outer edge of the partition ring 37 is in sealed contact with the inner wall of the adsorption cover 32. The partition ring 37 divides the annular channel 34 into two independent upper and lower parts. The ventilated structure 5 and the adsorbent 4 are both arranged on the partition ring 37. The partition ring 37 is provided with a vent hole 38 facing the ventilated structure 5. At the same time, the partition ring 37 is provided with a groove that matches the ventilated structure 5 so that the ventilated structure 5 can be installed through the groove.
[0040] It also includes an actuation cover 6, which is movably connected to the adsorption cover 32, and the actuation cover 6 also has a nozzle 7 connected to the dispensing pipe 25 of the press pump 2.
[0041] It is easy to understand that the fixing cover 31 can also be made of transparent material to facilitate the observation of the adsorbent 4. At the same time, the adsorbent 4 can also have a color indicator function to indicate the usage of the adsorbent 4. For example, anaerobic indicators have two colors, and aerobic and anaerobic indicators show two colors. This material is added to the adsorbent 4 (such as iron powder blocks) to observe the color change.
[0042] The process of using the fluid product dispenser provided in this embodiment of the invention is as follows:
[0043] In use, a pressing force is applied to the press pump 2 through the actuating cap 6. After undergoing the state changes of being pressed and reset, the press pump 2 will pump the fluid product out of the bottle 1 and spray it out through the nozzle 7 of the actuating cap 6. During the state change of the press pump 2, when the press pump 2 is pressed, the pump core 23 will descend and move away from the air inlet 26. At this time, air can flow along the gap between the actuating cap 6 and the adsorption cap 32, the gap between the pump cap 22 and the dispensing pipe 25, the pump housing 21, the air inlet 26 on the pump housing 21, and the space formed between the central channel 33 and the pump housing 21. The upper half of the gap space, the upper half of the annular space 34, the vent 38, the lower half of the annular space 34, the through hole 35, the lower half of the gap space formed between the central channel 33 and the pump housing 21, and the path of the bottle mouth enter the bottle body 1, and the oxygen in the bottle body 1 is removed by the adsorbent 4 when passing through the upper half of the annular space 34; when the pressing force of the pump 2 disappears, the pump core 23 will reset under the elastic force of the spring, and the pump core 23 will re-seal the air inlet 26 on the side wall of the pump housing 21 after resetting, so that the bottle body 1 is isolated from the outside.
[0044] Example 2
[0045] As shown in Figures 2-3, in this embodiment, the dispensing component is configured as a dropper 8. The dropper 8 typically includes a main body and a suction tube connected to the main body. By repeatedly squeezing the main body, the fluid product can be sucked into the main body through the suction tube.
[0046] This embodiment modifies the adsorption device 3 in Embodiment 1, specifically including:
[0047] The central channel 33 is arranged in reverse to form a supporting groove 39, which extends from the bottle opening into the bottle body 1, and there is a certain gap between the supporting groove 39 and the bottle opening, i.e., an air inlet gap. In addition, a one-way structure, such as a one-way valve, is provided at the bottom of the supporting groove 39, so that the fluid product can only flow out from the inside of the bottle body 1 and enter the supporting groove 39, and prevent air from entering the bottle body 1 from the supporting groove 39. In order to facilitate the dispensing of the fluid product, a straw that extends into the bottle body 1 is also connected to the lower end of the supporting groove 39.
[0048] Since the supporting 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 located on the outside of the supporting groove 39 and is closed by the adsorption cover 32, thereby forming an air intake channel. In addition, the groove 310 is also connected to the air intake gap formed between the supporting groove 39 and the bottle mouth through a first air hole 311 opened on the fixed cover 31.
[0049] The adsorption cap 32 has a second air hole 312 for connecting to the air intake channel (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 cap 32, thereby closing the second air hole 312 and blocking the air intake channel. Usually, a ring structure is also formed on the adsorption cap 32 to ensure that the dropper 8 can be placed stably.
[0050] When the dropper 8 is not in use, its main body (with a shell) is placed on the adsorption cover 32, and the second air hole 312 and the mounting hole opened on the adsorption cover 32 are closed. Its straw part extends into the bearing groove 39 after passing through the mounting hole on the adsorption cover 32.
[0051] When the dropper 8 draws in the fluid product, the fluid product can be drawn into the main body through the suction tube by repeatedly squeezing the main body. When the dropper 8 has drawn in 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 cap 32. After passing through the adsorbent 4 and the breathable structure 5, the air will enter the air inlet gap formed between the bearing groove 39 and the bottle mouth through the first air hole 311, and then enter the bottle body 1.
[0052] The embodiments of the present invention have been 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 can be made to these embodiments without departing from the principles and spirit of the present invention, and these variations still fall within the protection scope of the present invention.
