Description

Technical Field

[0001] The present application relates to the technical field of liquid packaging, and in particular to a liquid dispenser. Background Art

[0002] Existing liquid cosmetic packaging bottles have a relatively large capacity and are generally designed with a narrow bottle mouth to reduce pollution. In order to facilitate carrying, users generally pour cosmetics from a large bottle into a small bottle. However, due to the narrow bottle mouth of the large bottle, the liquid is difficult to pour out under the action of atmospheric pressure. On the other hand, forced pouring may cause spillage and waste.

[0003] Therefore, in order to divide the liquid in the narrow-mouthed packaging bottle into different containers, a liquid dispenser is generally used. Currently, there are three main types of liquid dispensers on the market, namely syringe-shaped dispensers, dropper-shaped dispensers and funnel-shaped dispensers.

[0004] A syringe-shaped dispenser is essentially an ordinary syringe that relies on a thin needle to reach into a narrow-mouth bottle to extract liquid. However, during the liquid dispensing process, the liquid needs to be transferred to a transfer container, increasing the risk of liquid contamination. In addition, syringe liquid extraction is not intuitive and it is easy to extract too much liquid, resulting in the excess liquid needing to be refilled into the narrow-mouth bottle. The liquid extraction process requires two hands to operate, which increases the difficulty of use.

[0005] A dropper-shaped dispenser is similar to a laboratory dropper. It sucks in liquid by squeezing a soft silicone or rubber head. However, the liquid needs to be transferred to a transfer container during the liquid dispensing process, which increases the risk of liquid contamination. The dropper is not intuitive for taking liquid and it is easy to take too much liquid, resulting in the excess liquid needing to be refilled into the narrow-mouth bottle. The dropper can only take a small amount of liquid at a time, so it needs to be repeatedly taken.

[0006] A funnel-shaped dispenser inserts a funnel into the mouth of the container to be filled and transfers the liquid by pouring. When pouring liquid from a narrow-mouthed bottle, it is easy to over-dump, making quantitative pouring impossible.

[0007] In order to avoid the above problems, the liquid dispenser needs to be further improved. Utility Model Content

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0040] In this application, the terms "comprises" and "comprising" and any variations thereof are intended to cover non-exclusive inclusions, for example, a system, product or apparatus comprising a list of elements is not necessarily limited to those elements expressly listed but may include other elements not expressly listed or inherent to such products or apparatuses.

[0041] See also Figures 1 to 4 An embodiment of the present application provides a liquid dispenser for dispensing liquid in a first container 10 into a second container 20. In the figure, the capacity of the first container 10 is larger and the capacity of the second container 20 is smaller, so the user can carry the second container 20 more conveniently.

[0042] Among them, the first container 10 and the second container 20 respectively have a first mouth 11 and a second mouth 21 (both mouths are narrow), and the liquid dispenser includes a first positioning seat 100 and a second positioning seat 200 arranged up and down when in use. The first positioning seat 100 has a first positioning groove 130 for sealing with the first mouth 11, and the second positioning seat 200 has a second positioning groove 210 for cooperating with the second mouth 21. Furthermore, the opening directions of the first positioning groove 130 and the second positioning groove 210 are opposite.

[0043] In order to smoothly transfer the liquid in the first container 10 into the second container 20, the first positioning seat 100 is provided with an infusion channel 111 for connecting the first container 10 and the second container 20, and an air intake channel 121 for connecting the first container 10 with the outside atmosphere. Correspondingly, the second positioning seat 200 is provided with a sealing portion 220 for closing the air intake channel 121.

[0044] Figure 2 The first container 10 is in the state of using the liquid dispenser, that is, the first mouth 11 of the first container 10 is inverted, and the orientations involved below are based on Figure 2 In this posture, in order to ensure smooth liquid discharge from the first container 10, preferably, the top height of the air inlet channel 121 is higher than the liquid infusion channel 111, so that the liquid can flow from the first container 10 into the second container 20 under the action of atmospheric pressure.

[0045] In this embodiment, the first positioning seat 100 and the second positioning seat 200 are movably matched, and the liquid dispensing device has an open state in which the blocking portion 220 disengages the air inlet channel 121, allowing the air inlet channel 121 to communicate with the atmosphere, thereby allowing liquid to flow from the first container 10 into the second container 20, and a closed state in which the blocking portion 220 closes the air inlet channel 121, thereby preventing liquid from flowing from the first container 10 into the second container 20. For details, see the closed state. Figures 2 and 3 , see the open status Figure 4 .

[0046] Furthermore, the first positioning seat 100 and the second positioning seat 200 can move relative to each other in the axial direction. Figures 3 to 7 To achieve circumferential positioning of the first and second positioning seats 100, 200, one of the first and second positioning seats 100, 200 may be provided with an axially arranged slot 150, and the other may be provided with a positioning rib 240 that cooperates with the slot 150. In the figure, the slot 150 is provided on the first positioning seat 100, and the positioning rib 240 is provided on the second positioning seat 200.

[0047] The second positioning seat 200 has a first height and a second height relative to the first positioning seat 100. When the second positioning seat 200 is at the first height (see Figure 2 ), at this time, the blocking portion 220 closes the air inlet channel 121, and the liquid dispenser is in a closed state. When the second positioning seat 200 is at the second height, the liquid dispenser is in an open state.

[0048] Since the first container 10 is inverted above the liquid dispenser when the liquid dispenser is in the open state, the first positioning seat 100 will move toward the second positioning seat 200 under the action of gravity (causing it to become closed). In order to prevent this situation, a snap-fit ​​structure that keeps the liquid dispenser in the open state is provided between the first positioning seat 100 and the second positioning seat 200. For example, in the figure, the first positioning seat 100 has an axially arranged diameter reduction portion 160 (the card groove 150 is provided on the diameter reduction portion 160), and the second positioning seat 200 is provided with an annular groove 250 that cooperates with the diameter reduction portion 160 (the positioning rib 240 is provided in the annular groove 250, see Figure 7 ), the engaging structure includes an annular groove 161 provided at the end of the reduced diameter portion 160 and an annular protrusion 251 provided in the annular groove 250. When the annular groove 161 and the annular protrusion 251 are engaged, the second positioning seat 200 is at the second height. Of course, when it is necessary to switch to the closed state, as long as opposite forces are applied to the first positioning seat 100 and the second positioning seat 200, the annular protrusion 251 is disengaged from the annular groove 250. Under the action of the applied force and gravity, the liquid dispenser can be quickly switched to the closed state. This operation can be completed with one hand.

[0049] In the closed state, the reduced diameter portion 160 is hidden in the second positioning seat 200 . Considering the aesthetic appearance, in this state, the outer surfaces of the first positioning seat 100 and the second positioning seat 200 are flush.

[0050] To keep the liquid dispenser in the closed state and avoid it being turned into the open state due to external interference, see Figure 4 The bottom end of the annular groove 250 is also provided with an axially arranged positioning block 252, and the top of the positioning block 252 has a guiding slope. When the liquid dispenser is in the closed state, the inner wall of the reduced diameter part 160 enters the bottom of the annular groove 161 through the guiding slope and has an interference fit with the positioning block 252, which can effectively prevent it from becoming open in the event of accidental touch and tipping.

[0051] See also Figures 4 to 7 The center of the first positioning seat 100 has a first boss 110 and a second boss 120 with an infusion channel 111 and an air intake channel 121 respectively. The first boss 110 extends downward into the space defined by the second positioning groove 210 (correspondingly, the second positioning seat 200 is provided with an avoidance hole 260 for avoiding the first boss 110), and the second boss 120 protrudes from the inside of the first positioning groove 130 and extends upward.

[0052] Preferably, the first protrusion 110 extends beyond the space defined by the second positioning groove 210 , and the second protrusion 120 extends beyond the space defined by the first positioning groove 130 .

[0053] For further information, see Figure 3 and Figure 4 The first mouth portion 11 and the second mouth portion 21 both have an inner surface and an outer surface. The first positioning groove 130 and the second boss 120 are respectively positioned and matched with the outer surface 13 and the inner surface 12 of the first mouth portion 11. The second positioning groove 210 and the first boss 110 are respectively positioned and matched with the outer surface 23 and the inner surface 22 of the second mouth portion 21.

[0054] In order to achieve a sealed fit with the first container 10, the inner wall surface of the first positioning groove 130 is provided with an internal thread 131 that matches the first mouth portion 11. Correspondingly, the first mouth portion 11 is provided with an external thread that matches the internal thread 131. Of course, in order to further improve the sealing performance, a sealing gasket 14 can also be provided between the first mouth portion 11 and the bottom of the first positioning groove 130 (see Figure 3 , the sealing gasket 14 is set at Figure 3 P position).

[0055] The infusion channel 111 and the air inlet channel 121 are arranged vertically in parallel and pass through the first positioning seat 100. The infusion channel 111 starts from the bottom surface of the first positioning groove 130. In this embodiment, the first boss 110 and the second boss 120 are arranged side by side, and the cross-section formed by the two is circular.

[0056] See also Figure 3 to Figure 5d The first positioning seat 100 has a receiving groove 140 that cooperates with the blocking portion 220 to connect to the air inlet channel 121. The first protrusion 110 extends from the receiving groove 140. The air inlet channel 121 forms an air inlet 141 on the bottom surface of the receiving groove 140. The blocking portion 220 extends into the receiving groove 140, and the end is used to close the air inlet 141.

[0057] The blocking portion 220 is loosely fitted with the accommodating groove 140 and has a vent hole 230 communicating with the second positioning groove 210 to allow communication with the atmosphere.

[0058] Furthermore, in order to improve the sealing performance of the blocking portion 220 when closing the air inlet channel 121, the end of the blocking portion 220 and the bottom surface of the receiving groove 140 are matched step structures. Figure 5d and Figure 7 The bottom surface of the accommodating groove 140 has a first step 142, and the first step 142 covers part of the air inlet 141. Correspondingly, the end of the sealing portion 220 has a second step 221, and the second step 221 covers part of the air vent 230. When in the closed state, the first step 142 is against the air vent 230, and the second step 221 is against the air inlet 141, thereby achieving a seal between the two. When liquid separation is required, the two are separated, and gas can flow from the air vent 230 to the air inlet 141 to achieve the function of ventilation.

[0059] Compared with the syringe-shaped dispensers, dropper-shaped dispensers and funnel-shaped dispensers in the prior art, the liquid dispenser of the present application can be switched from an open state to a closed state at any time with one hand (i.e., the first positioning seat and the second positioning seat are pressed with one hand), thereby achieving the effect of quantitative liquid discharge and single-handed shutdown, reducing the risk of liquid being contaminated by the outside world and being more convenient to use.

[0060] The technical features of the above-described embodiments may be combined in any manner. To simplify the description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as no contradiction exists between these combinations of technical features, they should be considered to be within the scope of this specification. When technical features of different embodiments are embodied in the same drawing, it can be deemed that the drawing also discloses examples of combinations of the various embodiments involved.

[0061] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the spirit of the present application, and such modifications and improvements are all within the scope of protection of the present application.
