Description

Technical Field

[0001] This utility model relates to the field of packaging technology, specifically to an adjustable cosmetic bottle. Background Technology

[0002] Cosmetic pump bottles are a common type of cosmetic packaging container. Visually, they typically consist of a bottle body, a pump dispenser, and a cap. The bottle body can be made of materials such as plastic or glass, and comes in various shapes and sizes. The pump dispenser is usually made of plastic and is cleverly designed to dispense a measured amount of cosmetic product through a pressing operation.

[0003] In the prior art, there is a flow-adjustable liquid pump head with publication number "CN219077921U"; the present invention includes a cap that is threadedly connected to the bottle mouth, a limiting seat connected to the cap, and a pressing device sleeved with the limiting seat. The pressing device includes a liquid outlet pipe, a pressing head, a pressing column, and a liquid pump that are connected in communication. By pressing the pressing head, the liquid pump pumps the liquid out to the liquid outlet pipe. The liquid output of the liquid outlet pipe is adjusted by the first step, the second step, the third step, and the fourth step set on the limiting seat.

[0004] However, existing technologies still have significant shortcomings, such as:

[0005] Although existing technologies can control the flow rate of the pump fluid through steps, this method has a limited adjustment range, only allowing flow rate adjustment within a few ranges. Furthermore, if the user applies too much force when pressing, the pump head may slide towards the lower step. Therefore, a cosmetic bottle that can be adjusted flexibly and reliably is needed. Utility Model Content

[0006] The purpose of this invention is to provide an adjustable cosmetic bottle to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An adjustable cosmetic bottle includes a bottle body, a liquid pump, and a press head. The liquid pump is mounted on the bottle body, and the press head is mounted on the press head. The press head is provided with a longitudinal chamber and a liquid outlet. The longitudinal chamber is connected to the liquid pump, and the liquid outlet is connected to the longitudinal chamber. The press head is provided with an adjustment component for adjusting the flow rate.

[0009] The adjustment assembly includes an annular groove and a sliding groove formed on the pressing head. An adjustment ring is rotatably disposed in the annular groove, and an adjustment plate is slidably disposed in the sliding groove. The adjustment ring has an internal thread, and the adjustment plate has an external thread, with the internal thread engaging with the external thread.

[0010] Preferably, the sliding groove extends beyond the height of the liquid outlet, and the adjusting plate has an adjusting hole.

[0011] Preferably, a wedge block is fixedly disposed in the sliding groove, with the wedge surface of the wedge block facing downwards.

[0012] Preferably, the adjusting ring is provided with a plurality of anti-slip strips.

[0013] Preferably, one of the adjustment rings is provided with an indicator bar, and the pressing head is provided with several scale grooves.

[0014] Preferably, the pressing head has a mounting hole at the position of the annular groove, a spring is provided in the mounting hole, and a positioning ball is fixedly provided at the end of the spring near the adjusting ring.

[0015] Preferably, a bottle cap is installed on the bottle body.

[0016] Preferably, the adjusting ring has several positioning holes at the end near the positioning ball.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. The threaded fit between the adjusting plate and the adjusting ring, along with the design of the adjusting hole, allows users to precisely control the flow rate of cosmetics. Whether a small amount is needed for delicate makeup application or a large amount for quick application, it meets different needs. For example, when applying eye makeup, only a very small amount of cosmetic may be required; the adjusting mechanism can minimize the flow rate, preventing waste and overuse.

[0019] 2. The scale grooves and indicator bars provide users with an intuitive reference for flow rate. Users can quickly and accurately adjust the flow rate to the desired level based on the markings in the scale grooves, improving ease of use and precision.

[0020] 3. The anti-slip strip on the adjustment ring increases friction when the user rotates it, making the adjustment operation smoother and more stable. Users can easily adjust the flow rate without the risk of inaccurate adjustments due to slippage. At the same time, the anti-slip strip design also improves the product's texture and feel, enhancing the user experience.

[0021] 4. The regulating plate can completely seal the liquid outlet, effectively preventing leakage caused by the decrease in viscosity of cosmetics due to temperature rise during travel or transportation. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-6 This utility model provides a technical solution:

[0031] An adjustable cosmetic bottle mainly consists of a bottle body, a liquid pump, and a press head. The liquid pump is securely mounted on the bottle body via a threaded connection or snap-fit. The press head is also detachably mounted on the liquid pump.

[0032] The liquid pump plays a crucial role in the entire adjustable cosmetic bottle. It typically consists of a pump body, piston, spring, and other components. The pump body is generally made of high-strength plastic, offering excellent sealing and durability. The pump body is securely mounted to the bottle using threaded connections or snap-fit ​​methods. Sealing gaskets or sealants are usually placed at the connection points to ensure no liquid leakage.

[0033] The piston reciprocates within the pump body, compressing and releasing the space inside the pump to draw liquid from the bottle into the pump and discharge it. The piston's movement is typically powered by a spring. When the press head is pressed, the spring is compressed, causing the piston to move downwards and draw liquid into the pump body. When the press head is released, the spring returns to its original position, pushing the piston upwards and discharging the liquid from the pump body (this device is commonly used in this technical field and is not shown in the schematic diagram).

[0034] The connection between the pump and the press head is also crucial. Generally, the pump outlet connects to the longitudinal chamber on the press head. Sealing measures are required at this connection point to ensure that the liquid flows smoothly from the pump into the longitudinal chamber without leakage.

[0035] The press head is equipped with a longitudinal chamber and a liquid outlet. The longitudinal chamber is connected to the liquid outlet channel of the liquid pump, allowing the liquid pumped by the pump to flow smoothly into the longitudinal chamber. The liquid outlet is connected to the longitudinal chamber, allowing the liquid to flow out from the liquid outlet after entering the longitudinal chamber.

[0036] The press head is also equipped with an adjustment component for regulating the flow rate. The adjustment component mainly includes an annular groove and a sliding groove formed on the press head. An adjustment ring is rotatably fitted into the annular groove.

[0037] An adjusting plate is slidably installed in the sliding groove, and an appropriate gap is maintained between the adjusting plate and the inner wall of the sliding groove to ensure that the adjusting plate can slide smoothly up and down in the sliding groove.

[0038] The adjusting ring has internal threads, and the adjusting plate has external threads; the internal and external threads engage with each other. When the user rotates the adjusting ring, the adjusting plate slides up and down in the sliding groove due to the action of the threads. When the adjusting plate slides downward, it gradually reduces the sealing area of ​​the liquid outlet, thereby increasing the pump flow rate; when the adjusting plate slides upward, it partially or completely blocks the liquid outlet, thus reducing the pump flow rate.

[0039] In another configuration, the sliding groove extends beyond the height of the outlet hole, ensuring the regulating plate has sufficient stroke to block the outlet hole to varying degrees. Simultaneously, regulating holes can be provided on the regulating plate; by misaligning these holes with the outlet hole, partial or complete blocking of the outlet hole can be achieved. For example, when the regulating hole and outlet hole are completely aligned, the pump flow rate is maximum; when they partially overlap, the flow rate is moderate; and when they are completely misaligned, the flow rate is zero.

[0040] A wedge block is fixedly installed in the sliding groove, and the wedge block is connected to the sliding groove by means of integral molding. The wedge surface of the wedge block faces downwards, allowing the operator to easily install the adjusting plate along the wedge surface when assembling it. Since the upper end of the wedge plate is horizontal, when the adjusting plate moves downwards to a certain extent, it will be blocked by the wedge plate, preventing it from falling off. This ensures that the adjusting plate remains within the sliding groove during use and will not accidentally fall off, thus guaranteeing the stability and reliability of the cosmetic bottle flow regulation function.

[0041] Example 2:

[0042] Based on Example 1, the adjustable cosmetic bottle has been further optimized. Several anti-slip strips are provided on the adjustment ring; these strips can be raised rubber strips or textured patterns etched onto the surface of the adjustment ring. The function of the anti-slip strips is to increase the friction when the user rotates the adjustment ring, making adjustment more convenient and precise. The anti-slip strips are fixed to the adjustment ring by means of integral molding or other methods.

[0043] One of the adjustment rings has an indicator bar, which can be a brightly colored mark or a raised arrow. The indicator bar helps the user quickly determine the position and adjustment direction of the adjustment ring. The press head has several graduated grooves, which can be evenly spaced or non-evenly spaced according to different flow requirements. The graduated grooves allow the user to intuitively understand the current flow adjustment level.

[0044] The pressing head has a mounting hole located at the position of the annular groove. A spring is installed in the mounting hole, and a positioning ball is fixedly installed at the end of the spring near the adjusting ring. The diameter of the mounting hole is slightly larger than the diameter of the spring, allowing the spring to extend and retract freely within the mounting hole. The positioning ball can be a metal ball or a plastic ball, with a diameter slightly larger than the diameter of the spring but smaller than the diameter of the mounting hole, allowing the positioning ball to extend out of the mounting hole under the action of the spring and contact the adjusting ring.

[0045] Furthermore, the adjusting ring has several positioning holes at the end near the positioning ball. When the user rotates the adjusting ring, the positioning ball will sequentially engage with different positioning holes under the action of the spring, creating a distinct clicking sensation and allowing the user to more accurately control the degree of flow adjustment. The depth and diameter of the positioning holes can be adjusted according to the size of the positioning ball to ensure that the positioning ball can be stably engaged in the positioning holes.

[0046] The bottle is fitted with a cap, which is secured to the bottle using a threaded connection or a snap-on connection. The cap's function is to protect the liquid inside the bottle from contamination and to prevent leakage.

[0047] Working Principle: During use, when the user needs to apply the cosmetic product, they press the pump head. At this time, the spring inside the pump is compressed, causing the piston to move downwards. Under pressure, the liquid inside the bottle is drawn into the pump body. When the pump head is released, the spring returns to its original position, pushing the piston upwards and discharging the liquid from the pump body. The liquid flows from the pump outlet into the longitudinal chamber on the pump head, and then flows out through the outlet hole that communicates with the longitudinal chamber.

[0048] Flow adjustment method 1: Slide the adjustment plate up and down

[0049] When the user rotates the adjusting ring, the internal thread on the adjusting ring engages with the external thread on the adjusting plate, and the adjusting plate slides in the sliding groove, causing the adjusting plate to move up and down in the sliding groove.

[0050] As the regulating plate slides downwards, it gradually reduces the area of ​​the outlet hole blocked, allowing more liquid to flow out of the outlet hole, thereby increasing the pump flow rate.

[0051] When the regulating plate slides upward, it will partially or completely block the liquid outlet, reducing the channel area for liquid outflow and thus reducing the pump flow rate.

[0052] Flow regulation method 2: Misalignment of regulating hole and outlet hole

[0053] The sliding groove extends beyond the height of the liquid outlet, ensuring that the adjusting plate has sufficient stroke to seal the liquid outlet to varying degrees.

[0054] An adjustment hole is provided on the adjustment plate. When the adjustment hole and the liquid outlet hole are completely aligned, the liquid can flow out smoothly through the adjustment hole and the liquid outlet hole, and the pump flow rate is at its maximum at this time.

[0055] When the regulating hole and the liquid outlet partially overlap, only a portion of the liquid can flow out through the overlapping part, resulting in a moderate pump flow rate.

[0056] When the regulating hole and the outlet hole are completely misaligned, the liquid cannot flow out through the regulating hole, the outlet hole is completely blocked by the regulating plate, and the pump flow rate is zero.

[0057] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
