Description

Technical Field

[0001] This utility model relates to skin care product packaging containers, specifically to a skin care product quantitative dispensing packaging container. Background Technology

[0002] In the skincare industry, consumers are placing increasingly higher demands on the user experience and efficacy of products. Among these demands, precisely controlling the dosage of skincare products used each time is crucial for ensuring optimal skincare results and avoiding waste. Traditional skincare packaging formats, such as open-top bottles, squeeze tubes, and manual pump dispensers, have several shortcomings in terms of dispensing precise amounts. Open-top bottles and squeeze tubes typically rely on the user's sense of touch to control the dosage, which can easily lead to inaccurate dosages, resulting in using too much or too little product, affecting both skincare efficacy and product waste. Furthermore, using open containers or direct contact with the bottle opening poses hygiene risks, easily causing product contamination and affecting product quality.

[0003] Manual pump heads improve dosage control to some extent, but they still have the following drawbacks: Inaccurate dosage: The amount of liquid dispensed with each press of a manual pump head is not entirely consistent. Factors such as pressing force and speed make precise dosing difficult, especially for skincare products requiring minute control. Inconvenient operation: Manual pressing requires the user to apply a certain amount of force, which is inconvenient for users with weaker hand strength, such as the elderly, children, or those with hand injuries. Prolonged or frequent pressing can also easily cause hand fatigue. Unstable dispensing: When pressed repeatedly, manual pump heads may experience unstable dispensing, such as intermittent dispensing or splashing, affecting the user experience.

[0004] Therefore, there is a need for a skincare product packaging container that is easy for users to operate and can stably dispense liquid. Utility Model Content

[0038] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0039] like Figures 1 to 7 As shown, the present invention provides a quantitative dispensing packaging container for skincare products, comprising:

[0040] The container body 10 has a cylindrical structure and its top inner wall is provided with internal threads 13;

[0041] Storage cavity 20, located inside container body 10, is used to hold skin care products;

[0042] The metering pump assembly 30 includes a piston 31 and a pump body 32. The pump body 32 is a hollow cylindrical structure with an external thread 33 on its lower outer wall. The external thread 33 is engaged with the internal thread 13 on the top of the container body 10. The piston 31 is located in the inner cavity of the pump body 32. A connecting part 34 is coaxially provided on the top of the piston 31. The outer circumferential surface of the connecting part 34 is threaded.

[0043] The rotary adjustment mechanism 40 includes a rotary cover 41 and a return spring 42. The rotary cover 41 is located on the top of the pump body 32. The rotary cover 41 has a cylindrical groove 43 inside. The inner surface of the cylindrical groove 43 is provided with several flanges in a ring. The flanges are threadedly engaged with the connecting part 34. The return spring 42 is located between the cylindrical groove 43 and the pump body 32.

[0044] One end of the return spring 42 is fixedly connected to the cylindrical groove 43, and the other end of the return spring 42 is fixed to the piston 31.

[0045] Specifically, this embodiment includes the following preferred structures,

[0046] 1. Container body 10:

[0047] The container body 10 adopts a cylindrical structure design with an overall height of 13mm, an outer diameter of 30mm, and a wall thickness of 1.5mm. The upper end of the container body 10 is open, and the inner wall of the opening is machined with internal threads 13 with a thread depth of 8mm.

[0048] The container body 10 is injection molded from PMMA frosted acrylic.

[0049] 2. Storage cavity 20:

[0050] The storage cavity 20 is a hollow space formed inside the container body 10, with an effective volume of 30ml. The inner wall of the storage cavity 20 is smooth and has no dead corners, making it easy to clean and fill with skin care products.

[0051] The storage cavity 20 is used to hold and store skincare products. The transparent material design, combined with the container body 10, allows users to easily see the remaining amount of skincare products.

[0052] 3. Metering pump assembly 30:

[0053] Pump body 32:

[0054] The pump body 32 is cylindrical. The lower outer wall of the pump body 32 is provided with an external thread 33. The specification of the external thread 33 matches the internal thread 13 of the container body 10. The upper end of the pump body 32 is the pump outlet. A circular through hole with a diameter of 3mm is provided at the outlet for connecting the liquid release pipe 50.

[0055] The pump body 32 is injection molded from corrosion-resistant PP plastic. PP plastic has good chemical corrosion resistance and processing performance, which can ensure that the pump body is not easily deformed or damaged during long-term use.

[0056] 4. Rotary adjustment mechanism 40:

[0057] The same plastic material as the container body 10 or pump body 32 can be used, such as PMMA or PP. PMMA plastic has better hardness and surface gloss; if a higher aesthetic finish is desired, PMMA can be considered.

[0058] In this invention, the color can be selected according to design requirements, and it is usually contrasted with the color of the container body or pump body to highlight the rotation adjustment function.

[0059] The working principle of this utility model:

[0060] Quantitative dispensing principle: When the rotating cap 41 is rotated, the flange of the cylindrical groove 43 inside the rotating cap engages with the thread of the connecting part 34 of the piston 31. Due to the restriction of the flange, the rotational motion of the rotating cap is converted into the axial upward motion of the piston 31. The piston moves upward within the pump body 32, squeezing out the skin care product inside the pump body, thus achieving quantitative dispensing.

[0061] Rotary adjustment mechanism: The angle at which the rotating cap is rotated determines the upward movement distance of the piston 31, thereby controlling the amount of liquid dispensed each time. The larger the rotation angle, the greater the piston movement distance and the greater the liquid dispensed; conversely, the smaller the rotation angle, the less liquid dispensed. By pre-calibrating the correspondence between the rotation angle and the liquid dispensed, scales or markings can be set on the rotating cap to facilitate precise adjustment of the liquid dispensed by the user.

[0062] Reset function: When the rotating cover stops rotating, the reset spring 42 will push the rotating cover 41 and piston 31 downward to reset to the initial position, ready for the next liquid dispensing.

[0063] Implementation, for example Figures 1 to 3 As shown,

[0064] The pump body 32 has a hollow cylindrical structure with a cylindrical outer shell and an inner cavity that houses the piston 31. The lower outer wall of the pump body 32 is provided with an external thread 33, which matches the internal thread 13 on the top of the container body 10. This threaded connection ensures a secure connection between the pump body and the container body. The design of the external thread 33 ensures a firm connection between the pump body and the container body while also facilitating disassembly and cleaning.

[0065] Implementation, for example Figure 1 and Figure 3 As shown, preferably, it also includes:

[0066] The outlet pipe 50 is a long and thin tubular structure. Its inlet end 51 is sealed to the top outlet of the pump body 32. The outlet end 52 of the outlet pipe 50 is provided with a hemispherical silicone sealing head 53.

[0067] The outlet pipe 50 is a long, slender tubular structure, with one end 51 sealed to the outlet at the top of the pump body 32. This connection uses a sealing ring or rubber gasket to ensure no liquid leakage, preventing the skincare product from being lost or contaminating the external environment during delivery. The outlet pipe 50 is made of flexible material, ensuring the pipe has a certain degree of flexibility for easy operation and use.

[0068] The outlet end 52 of the dispensing tube 50 is equipped with a hemispherical silicone sealing head 53. This silicone sealing head 53 is elastic and chemically resistant, ensuring a good seal when the skincare product is dispensed from the dispensing tube 50, preventing leakage. The hemispherical design of the silicone sealing head allows the outlet end to fit snugly against the skin, providing a comfortable application experience, and prevents air from entering the container when not in use, reducing oxidation or deterioration of the skincare product.

[0069] Preferably, the side wall of the container body 10 is provided with an axially extending observation groove 11;

[0070] A transparent acrylic plate 12 is embedded in the groove of the observation slot 11;

[0071] The transparent acrylic sheet 12 has a measuring scale on its surface.

[0072] The side wall of the container body 10 has one or more observation slots 11 extending along the longitudinal axis. These observation slots 11 are designed as narrow, elongated slots parallel to the outer wall of the container, allowing users to easily observe the remaining amount of skincare product inside. In addition to their observation function, the observation slots 11, when used in conjunction with the transparent acrylic plate 12, enhance the visual appeal of the container.

[0073] A transparent acrylic plate 12 is embedded inside the observation slot 11. The transparent acrylic plate 12 has good transparency, ensuring that the remaining amount of skincare product is clearly visible. Through the installation of acrylic strips, the observation slot 11 not only improves the aesthetics of the container but also increases its durability. The acrylic strips are made of a material with strong impact resistance and corrosion resistance, making them less prone to scratches or discoloration during long-term use.

[0074] The transparent acrylic sheet 12 features a measuring scale on its surface. The scale is created using a metal plating or laser etching process, with the graduations etched onto the acrylic strip surface. This scale helps users accurately determine the amount of skincare product remaining in the container, facilitating refills or replacements. The design of the measuring scale ensures clarity and legibility.

[0075] Preferably, the storage cavity 20 has a double-layer structure;

[0076] The inner layer 23 of the storage cavity 20 is made of high polyethylene material;

[0077] The outer layer 24 of the storage cavity 20 is made of frosted transparent polycarbonate material.

[0078] The storage chamber 20 features a double-layer structure, consisting of an inner layer 23 and an outer layer 24. This double-layer structure not only enhances the strength and durability of the container but also provides better protection, ensuring that the skincare products inside the storage chamber are not affected by the external environment and extending their lifespan.

[0079] The inner layer 23 of the storage chamber is made of high-density polyethylene (HDPE). HDPE has excellent chemical stability, corrosion resistance, and UV resistance, effectively preventing chemical reactions or deterioration of skincare products when in contact with the container. The low hygroscopicity of HDPE ensures that the skincare products inside the container maintain their freshness for a longer period and are not affected by the container's material. The HDPE inner layer 23 effectively provides a strong protective barrier, reducing the risk of damage to skincare products due to external pressure or impact.

[0080] The outer layer 24 of the storage cavity is made of transparent PC polycarbonate. Polycarbonate is a high-strength engineering plastic with excellent impact resistance and heat resistance, ensuring that the container is not easily broken or deformed during use. The transparent design gives the container a unique appearance while clearly displaying the amount of skincare product inside.

[0081] Implementation, for example Figure 3 As shown, preferably, the silicone sealing head 53 is provided with a cross-shaped cut;

[0082] The silicone sealing head 53 has a cross-shaped cut at its bottom. This cross-shaped cut provides better cutting results and liquid flow control. The cross-shaped cut effectively controls the amount of skincare product dispensed, ensuring a uniform and stable flow each time. This design also reduces liquid waste and prevents leakage or uneven flow due to poor sealing or an improper cut shape.

[0083] Optionally, the cross-shaped cut thickness is designed to be 0.3-0.5mm to ensure sufficient strength and stability, while allowing for quick and precise flow control when liquid skincare products are needed. This thickness range enables the silicone sealing head 53 to maintain a tight seal while providing good elasticity and cutting performance, allowing it to open and dispense an appropriate amount of skincare product under slight pressure. A cut that is too thin may result in incomplete sealing or difficulty in cutting, while a cut that is too thick may affect cutting efficiency and sealing performance; this range provides optimal performance.

[0084] Implementation, for example Figure 4 and Figure 5 As shown, preferably, the bottom of the storage cavity 20 is provided with an annular groove 25. The bottom of the inner cavity of the container body 10 has a snap-fit ​​structure that matches the annular groove 25.

[0085] The bottom of the storage cavity 20 is designed with an annular groove 25. This groove is circular and located at the outer edge of the bottom of the storage cavity. It cooperates with the snap-fit ​​structure inside the container body 10 to ensure greater stability at the bottom. The annular groove 25 has a certain depth to accommodate and fix the snap-fit ​​structure, preventing the storage cavity 20 from loosening or falling off from the container body 10 during use.

[0086] Preferably, the measuring scale of the transparent acrylic sheet includes raised graduation lines.

[0087] The graduated lines make it easy for users to see the amount of skincare product remaining in the container.

[0088] Implementation, for example Figure 6 As shown, preferably, the container body is also provided with several measuring scale bars, and the rotating cover is provided with corresponding indicator scale lines.

[0089] To further enhance the user experience and provide a more intuitive display and control of the amount of skincare product dispensed, a preferred embodiment of this invention includes an added measuring scale bar on the container body 10 and corresponding indicator scale lines on the rotating cap 41. This combination allows users to visually understand and adjust the amount of product dispensed each time, thereby better meeting their personalized skincare needs.

[0090] The graduated scale bars are preferably positioned on the outer surface of the cylindrical sidewall of the container body 10. This placement ensures the scale bars are clearly visible without compromising the overall structural strength and aesthetics of the container body. The scale bars can be arranged vertically, parallel to the axis of the container body, or in a circular pattern, surrounding the cylindrical wall of the container body. Considering their compatibility with the indicator lines on the rotating cap, a vertical arrangement is more intuitive and easier to read.

[0091] Optional in this utility model,

[0092] Measuring scale bars can take many forms, for example:

[0093] Printed graduation lines: The most common and economical method is to print a series of evenly spaced graduation lines of equal length directly on the outer surface of the container. Different colored inks can be used for the graduation lines, such as black or dark colors that contrast sharply with the container's main color, to enhance readability. Numerical values, such as "5ml," "10ml," and "15ml," can be printed directly next to the graduation lines, or text labels such as "small dose," "medium dose," and "large dose" can be used for easy user comprehension.

[0094] Embossed scale lines: These are scale lines with a raised or recessed texture created on the outer surface of the container body through processes such as molding or laser engraving. These scale lines not only provide visual legibility but also enhance tactile feedback, allowing users to perceive the scale positions by touch and operate the container even in low light conditions. Embossed scale lines can be combined with color filling to further improve the visual effect.

[0095] Inlaid graduated scale plates: A groove or recessed area is pre-drilled on the outer surface of the container body, and a pre-made metal or plastic graduated scale plate is inlaid therein. The scale plate can be made with etching, laser engraving, or printing to create scale lines and numerical markings. Inlaid graduated scale plates offer a more textured and upscale feel, are more wear-resistant, and are less likely to fall off.

[0096] In summary, this utility model, by combining the container body 10, storage cavity 20, metering pump assembly 30, and rotary adjustment mechanism 40, achieves quantitative dispensing of skincare products. The container body adopts a cylindrical structure with an internal thread at the top for easy connection to the metering pump assembly; the storage cavity is used to safely hold the skincare products and preferably adopts a double-layer structure and transparent material. The metering pump assembly is the core component, achieving quantitative liquid dispensing through the coordinated work of the piston and pump body; the rotary adjustment mechanism allows users to adjust the dispensing volume each time by rotating the rotating cap to meet personalized needs. This utility model also features an automatic reset function achieved by the return spring 42, as well as optional preferred structures such as the dispensing tube 50, observation slot 11, metering scale, silicone sealing head 53, and annular groove 25, further enhancing the user experience. These designs make this quantitative dispensing packaging container for skincare products not only convenient to operate and accurate in dispensing, but also effectively protect the contents.

[0097] The working principle of the quantitative dispensing packaging container for skincare products described in this utility model is as follows:

[0098] When the user rotates the rotating cap 41, the flange on the cylindrical groove 43 inside the cap engages with the threaded structure of the piston 31 connection 34. This engagement converts the rotational motion of the cap into the linear upward motion of the piston 31. As the piston 31 moves upward within the pump body 32, the internal space of the pump body decreases, thereby squeezing the skincare product in the storage chamber 20. Driven by pressure, the skincare product flows out along the outlet of the pump body 32, through the dispensing pipe 50, and finally from the cross-shaped cut of the silicone sealing head 53, achieving a quantitative dispensing. By rotating the cap, the user can control the displacement distance of the piston 31, thereby adjusting the dosage of skincare product dispensed each time to meet the usage needs of different scenarios. When the rotation stops, the return spring 42 quickly releases its elastic potential energy, pushing the cap 41 and piston 31 back to their initial positions to prepare for the next quantitative dispensing.

[0099] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
