Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of painted packaging boxes, specifically relating to face-painted packaging boxes, and more particularly to portable face-painted packaging boxes. Background Technology
[0002] With the enrichment of cultural and entertainment activities and the increasing demand for personalization, face painting, as a form of temporary makeup, is becoming increasingly popular in scenarios such as children's entertainment, festival celebrations, sporting events, and themed parties. Correspondingly, the market demand for portable face painting products (which typically include palettes of multiple colors and matching brushes) is also growing.
[0003] In existing technologies, face painting kits often employ an open or wide-mouthed recessed design for their pigment storage units; users can directly use the included brush to dip into the paste or liquid pigments in the recessed area to paint.
[0004] However, paintbrushes inevitably come into contact with the user's skin during use, and sebum, sweat, dust, and microorganisms from the environment on the skin's surface will adhere to the brush. When the same paintbrush is repeatedly dipped in different colors of paint, especially when it is dipped into the main paint container again, serious cross-contamination occurs, and there is a possibility of microorganisms (such as bacteria and mold) entering the paint. This can cause the paint to undergo chemical denaturation, resulting in waste.
[0005] Therefore, how to avoid pigment contamination in the paint tank due to the dipping of a single brush is a technical problem that urgently needs to be solved in this field.
[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content
[0007] This disclosure provides at least one portable face painting packaging box to solve the technical problem of paint pooling caused by dipping a single brush in paint.
[0008] In a first aspect, embodiments of this disclosure provide a portable face painting packaging box, comprising: a box body having a plurality of recesses inside; a dispensing container disposed within the recesses, the dispensing container being adapted to store paste-like pigment; and a partition disposed within the dispensing container and adapted to move downward along the central axis of the dispensing container, the surface of the partition having evenly distributed discharge holes; wherein, when the partition is configured to move downward, it squeezes the pigment in the dispensing container through the discharge holes to the top of the partition, thereby isolating excess pigment below and allowing it to be picked up by a paintbrush.
[0009] In one alternative embodiment, the spacer is made of an elastic material with a Shore A hardness of 40-60.
[0010] In one optional embodiment, the inner wall of the dispensing tank is provided with at least two guide posts, and the guide posts are provided with metering grooves; the edge of the partition is provided with guide grooves that cooperate with the guide posts, and the guide grooves are provided with protrusions; wherein, the partition is configured to move downward to squeeze the pigment through the discharge hole to the top of the partition, and the protrusions and metering grooves are properly engaged to limit the downward movement of the partition.
[0011] In one optional embodiment, the inner wall of the dispensing tank is provided with a threaded groove; the edge of the partition is provided with a threaded strip that engages with the threaded groove; wherein the partition is configured such that, by rotational drive, the threaded strip spirals down along the threaded groove to quantitatively extrude pigment through the discharge hole to the top of the partition.
[0012] In one optional embodiment, an elastic diaphragm is provided inside the discharge hole, and a cross slit is provided in the center of the diaphragm; the cross slit is closed under normal conditions, and opens when the diaphragm is pressed down by the pigment to allow the pigment to pass through, and automatically resets and closes after the pressure is released.
[0013] Secondly, this disclosure also provides a portable face painting packaging box, comprising: a dispensing container suitable for storing paste-like pigment; a partition disposed within the dispensing container and adapted to move downward along the central axis of the dispensing container, wherein the surface of the partition is evenly distributed with dispensing holes, and an elastic diaphragm is disposed within the dispensing holes, the diaphragm having a cross-shaped slit in its center; wherein, when the partition is configured to move downward, the pigment in the dispensing container is squeezed through the cross-shaped slit to the top of the partition to isolate excess pigment below and allow the paintbrush to pick it up.
[0014] In one alternative embodiment, the spacer is made of an elastic material with a Shore A hardness of 40-60.
[0015] In one optional embodiment, the inner wall of the dispensing tank is provided with at least two guide posts, and the guide posts are provided with metering grooves; the edge of the partition is provided with guide grooves that cooperate with the guide posts, and the guide grooves are provided with protrusions; wherein, the partition is configured to move downward to squeeze the pigment through the discharge hole to the top of the partition, and the protrusions and metering grooves are properly engaged to limit the downward movement of the partition.
[0016] In one optional embodiment, the inner wall of the dispensing tank is provided with a threaded groove; the edge of the partition is provided with a threaded strip that engages with the threaded groove; wherein the partition is configured such that, by rotational drive, the threaded strip spirals down along the threaded groove to quantitatively extrude pigment through the discharge hole to the top of the partition.
[0017] The beneficial effects of this utility model are that it provides a portable face painting packaging box, which uses the downward movement of the partition to squeeze the paint through the discharge hole to the top, achieving the effect of taking out the paint as needed. The partition physically isolates the unused paint below, preventing the paint from being contaminated by a single brush repeatedly dipping into the paint, thus solving the problem of wasting unused paint caused by direct use of traditional open paint boxes.

Rather, the use of the terms “example,” “exemplary,” etc., is intended to present concepts in a specific manner.
[0028] Research has revealed the following drawbacks of existing technologies: In related technologies, face painting boxes often employ an open or wide-mouthed recessed design for their pigment storage units; users directly use the included brush to dip into the paste or liquid pigment within the recessed area to paint.
[0029] However, paintbrushes inevitably come into contact with the user's skin during use, and sebum, sweat, dust, and microorganisms from the environment can adhere to the brush. When the same paintbrush is repeatedly dipped in different colors of paint, especially when it is dipped into the main paint container again, serious cross-contamination occurs, and there is a possibility of microorganisms (such as bacteria and mold) entering the paint. This can cause the paint to undergo chemical changes, resulting not only in waste but also in safety hazards that may affect health.
[0030] Therefore, how to avoid the problem of pigment buildup in the paint tank due to the dipping of a single brush is a technical problem that urgently needs to be solved in this field.
[0031] The shortcomings of the above solutions are the result of the utility model inventor's practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as contributions made by the utility model inventor to this disclosure.
[0032] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0033] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0034] like Figures 1 to 5 As shown, some embodiments provide a portable face painting packaging box, including: a box body 1, which has a plurality of recesses 11 inside; the box body 1 is the basic structure and outer shell of the entire product. The recesses 11 (or slots) inside are used to accurately and securely accommodate and fix individual dispensing cans 2. This ensures that each dispensing can 2 will not collide with each other or fall out of the box during transportation and carrying.
[0035] Multiple independent dispensing containers 2 are integrated into a compact box 1, which makes it convenient for users to classify, store and carry multiple colors, realizing the core function of "portability" of the product; in addition, the recessed part 11 plays a role in buffering and fixing the dispensing containers 2, preventing the containers from being damaged by shaking or squeezing, protecting the pigments inside, making the inside of the product look neat and orderly, and improving the user experience.
[0036] The dispensing tank 2 is located within the recess 11 and its interior is suitable for storing paste-like pigments. The dispensing tank 2 is an independent container for storing single-color pigments and is the core functional unit of the packaging box. Each dispensing tank 2 carries a single color of pigment and integrates mechanical structures such as guide posts 21 (or threaded grooves 35).
[0037] It achieves color isolation, preventing different pigments from contaminating each other during storage; damage or contamination of a single dispensing tank 2 will not affect other colors; dispensing tank 2 provides an installation base for internal structures such as partition 3, guide post 21 / threaded groove 35.
[0038] As a preferred embodiment, the dispensing tank 2 can be made of transparent or semi-transparent plastic (such as PET, PS, PP); the transparent material allows users to see the remaining amount and color of the pigment in the tank intuitively without having to open it.
[0039] The partition 3, located inside the dispensing tank 2 and adapted to move downwards along the central axis of the dispensing tank 2, is the core active component, and its working principle is similar to that of a syringe piston. Initially, the partition 3 is located above or on top of the pigment; when the user presses down or rotates it, it squeezes the pigment below it, forcing the pigment to rise through the discharge hole 31 on its surface to the top of the partition 3, forming a pool of fresh pigment available for dipping.
[0040] Each time you use it, you only need to squeeze out a small amount of the required pigment, avoiding the exposure of too much pigment at once, which would cause it to dry and be wasted. The separator 3 physically separates the squeezed-out pigment above from the large amount of stored pigment below, effectively preventing the pigment below from drying and forming a skin due to contact with air, which greatly extends the life of the entire can of pigment. It should be further noted that even if the small amount of pigment above the separator 3 dries or becomes contaminated, the overall loss is very small, and fresh pigment can be squeezed out for the next use.
[0041] The spacer 3 is made entirely of an elastomer (such as silicone, TPE thermoplastic elastomer, or TPU thermoplastic polyurethane elastomer), which meets the Shore A hardness requirement of 40-60 degrees. As a preferred embodiment, silicone has excellent chemical inertness, is safe and non-toxic, and is an excellent choice. TPE / TPU is easy to process and has good adhesion to the plastic matrix.
[0042] When its hardness is between Shore A 40 and 60, it ensures that the partition 3 has sufficient rigidity to effectively squeeze the paste pigment when pressed down; it also has sufficient flexibility to form a good seal with the inner wall of the dispensing tank 2, and can smoothly engage and disengage with the metering groove 211 or threaded groove 35 on the guide column 21; in addition, it has good sealing performance, with the edge of the partition 3 closely fitting the inner wall of the dispensing tank 2 to prevent pigment from leaking from the edge to the top, and also to prevent air from entering from the edge to the bottom.
[0043] The surface of the partition 3 is evenly distributed with discharge holes 31; wherein, when the partition 3 is configured to move downward, it squeezes the pigment in the dispensing tank 2 through the discharge holes 31 to the top of the partition 3, so as to isolate the excess pigment below and allow the paintbrush to pick it up.
[0044] The spacer 3 is made of an elastic material with a Shore A hardness of 40-60 degrees.
[0045] The inner wall of the dispensing tank 2 is provided with at least two guide posts 21, and a metering groove 211 is provided on the guide posts 21; the edge of the partition 3 is provided with a guide groove 34 that cooperates with the guide posts 21, and a protrusion 341 is provided in the guide groove 34; wherein, the partition 3 is configured to move downward, squeezing the pigment through the discharge hole 31 to the top of the partition 3, and the protrusion 341 and the metering groove 211 are properly engaged to limit the downward movement of the partition 3.
[0046] Guide posts 21 are ribs vertically fixed to the inner wall of the distribution tank 2; their main function is to guide the partition 3 to move strictly downwards along the vertical direction (e.g., Figure 2 (in the F1 direction) to prevent it from tilting or rotating, thereby ensuring the effectiveness and sealing of the extrusion action; the metering groove 211 is a recess or notch on the guide post 21.
[0047] The guide column 21 ensures that the extrusion process is smooth and straight, and will not cause extrusion failure or sealing failure due to the misalignment of the partition 3. It works with the protrusion 341 on the partition 3 to achieve a "click" quantitative discharge. Each time it is pressed, the protrusion 341 slides from one quantitative groove 211 to the next, which means that a certain amount of pigment has been extruded, making it convenient for users to control the amount used.
[0048] The guide post 21 and the main body of the dispensing tank 2 are integrally injection molded and made of the same material (such as PP or ABS). The material is required to have sufficient strength and wear resistance to withstand repeated sliding of the protrusion 341.
[0049] The guide groove 34 is an opening groove on the edge of the partition 3, which slides with the guide post 21 to restrict the partition 3 to move only up and down; the protrusion 341 (a small hemispherical or wedge-shaped dot) is located in the guide groove 34.
[0050] The guide groove 34 and the guide post 21 work together to achieve precise vertical guidance; the protrusion 341 and the metering groove 211 form a simple ratchet mechanism. When pressed down, the protrusion 341 undergoes elastic deformation and slides out of the current metering groove 211; when it reaches the next metering groove 211, the protrusion 341 is locked into the groove under the action of the rebound force, realizing positioning and limiting; in addition, after locking, it can effectively prevent the partition 3 from retracting due to the rebound force of the compressed pigment below, maintaining the stable state of the extruded pigment.
[0051] The inner wall of the dispensing tank 2 is provided with a threaded groove 35; the edge of the partition 3 is provided with a threaded strip 22 that engages with the threaded groove 35; wherein, the partition 3 is configured such that, by rotational drive, the external threaded strip 22 spirals down along the internal threaded groove 35, so as to quantitatively squeeze the pigment through the discharge hole 31 to the top of the partition 3.
[0052] The threaded groove 35 (internal thread) on the inner wall of the dispensing tank 2 meshes with the threaded strip 22 (external thread) on the edge of the partition 3, forming a helical drive pair. During use, rotating the partition 3 (e.g., rotating one revolution) drives its descent (e.g., ...). Figure 4 (It rotates in the F2 direction), and the rotation angle is precisely proportional to the descent distance, achieving more accurate and linear quantitative discharge control, which is suitable for scenarios with more precise dosage requirements.
[0053] The threaded drive has a self-locking characteristic. Once rotation stops, the thread engagement can reliably prevent the partition 3 from being pushed back by the pigment pressure, maintaining an extremely stable state. Rotation operation is more controllable than direct pressing.
[0054] The spacer threaded strip 22 is integrally formed with the spacer 3 and is made of an elastomer (silicone, TPU, etc.). Its elastomer deformation ability allows it to be smoothly screwed into the threaded groove 35 of the hard plastic while maintaining sufficient biting force to achieve self-locking.
[0055] An elastic diaphragm 32 is provided inside the discharge hole 31, and a cross slit 33 is provided in the center of the diaphragm. The cross slit 33 is closed under normal conditions, and opens when the diaphragm 3 is pressed down by the pigment to allow the pigment to pass through. After the pressure is released, it automatically resets and closes.
[0056] The elastic diaphragm 32 is a secondary sealing structure located in each discharge port 31. The elastic diaphragm 32 is made of silicone with a Shore A of 10-30 degrees. It is essentially a miniature one-way valve. Under normal conditions, the cross slit 33 is tightly closed due to the contraction force of the elastic material. When the diaphragm 3 is pressed down, the pressure of the pigment below increases, and the pressure will open the cross slit 33, allowing the pigment to pass through. When the pressure is released, the cross slit 33 closes automatically.
[0057] The elastic diaphragm 32 enhances the sealing effect, not only preventing air from flowing back into the lower part of the dispensing tank 2 from the discharge port 31—a crucial guarantee against pigment drying—but also effectively preventing pigment leakage even when the product is inverted or tilted due to the closure of the cross-shaped seam 33. This greatly improves the product's portability and reliability, effectively ensuring that each extrusion is fresh, air-free pigment. Some embodiments provide a portable face painting packaging box, including: a dispensing tank 2, the interior of which is adapted to store paste-like pigment; a partition 3, which is disposed inside the dispensing tank 2 and adapted to move downward along the central axis of the dispensing tank 2, the surface of the partition 3 having evenly distributed discharge holes 31, an elastic diaphragm 32 disposed inside the discharge holes 31, and a cross slit 33 being formed in the center of the diaphragm; the partition 3 is made of an elastic material with a Shore A hardness of 40-60 degrees.
[0058] The partition 3 is configured to, when moving downwards, squeeze the pigment in the dispensing tank 2 through the cross slit 33 to the top of the partition 3, so as to isolate the excess pigment below and allow the paintbrush to pick it up.
[0059] The inner wall of the dispensing tank 2 is provided with at least two guide posts 21, and a metering groove 211 is provided on the guide posts 21; the edge of the partition 3 is provided with a guide groove 34 that cooperates with the guide posts 21, and a protrusion 341 is provided in the guide groove 34; wherein, the partition 3 is configured to move downward, squeezing the pigment through the discharge hole 31 to the top of the partition 3, and the protrusion 341 and the metering groove 211 are properly engaged to limit the downward movement of the partition 3.
[0060] The inner wall of the dispensing tank 2 is provided with a threaded groove 35; the edge of the partition 3 is provided with a threaded strip 22 that engages with the threaded groove 35; wherein, the partition 3 is configured such that, by rotational drive, the external threaded strip 22 spirals down along the internal threaded groove 35, so as to quantitatively squeeze the pigment through the discharge hole 31 to the top of the partition 3.
