Compact, especially in the cosmetic packaging box, is the design of small and easy to carry the cosmetic case. In the packaging of existing cosmetics in the powder box is usually used to pack powder, wet and dry powder, blush, eye shadow, etc., the contents of the package can be powder, baking powder or wet powder. The design of the powder box according to the package of products and processing technology will be different, the following we simply introduce the basic structure of the cartridge, design and functional points.
 
The composition of the powder boxThe composition of the powder box:
Currently on the market the most common way to open the box is open to open, there are sliding open the powder box, common in small powder box. In order to put a lot of powder together, will these two open way together. Rotation is the most mainstream form of the structure of the powder box, the following we mainly to open the rotation as an example to discuss the structure of the cartridge.
The most basic composition of the toner cartridge includes the cover, the bottom, the lens (sometimes omitted), the position of the powder and the position of the puff; the rotating toner cartridge will have a rotating shaft, and the sliding open cartridge will have a sliding guide (usually designed On the bottom of the cover). The following figure shows the composition of the most common rotary open cartridge, including the cap, the Base, the Mirror, the Insert, the Hinge Pin, and the Button. Toner will be placed inside the Insert, Puff on the Base inside.
The powder and puff of the round powder box are usually placed up and down two layers, while the square powder box is usually placed around. The figure below is the finished product.
Powder cover, bottom, powder seat material is usually plastic, the most commonly used materials are ABS, SAN, PCTA, PMMA, PP and so on. ABS is generally required for the part of the coating process; SAN is used for general transparent parts, or with certain incorporation of ABS to improve the brightness of parts; PMMA is generally used for thick-walled transparent parts (PMMA intolerance alcohol); PCTA is generally used for High chemical resistance of the powder box; PP is generally used in the sealed requirements of the powder box. Lens material is generally painted glass, the thickness of about 1.3mm, usually requires lead-free lead (Lead Free). Very few will have plastic, but the plastic lens effect is far less than glass lenses, easy to deformation, resulting in shadow distortion. After the new nail is generally used in stainless steel nails (solid steel nails, hollow steel nails, hollow mandrel, roll nails, etc.), copper wire is generally used in opaque powder, plastic nails (general PET material) for Back to the new bump to reach the cover function on the powder box.
The function of the powder box and design points
From the basic structure of the powder box we can see the main function of the powder box is to protect the product, easy to use. Its functional points are also from the actual point of view of the use of the definition, the common functional requirements are as follows:
1. open box force: open box force related to the direct use of the product feel, depending on the size of the product to open the feel comfortable to determine the scope of the principle. Commonly used to open the box to open the box power of 0.2-0.9kgf.
2. Integrity: The integrity of the box is used in the course of the combination should not be separated from the parts will not be separated because of normal use, usually with the separation between components and drop test to check. Inter-component separation force is usually not easy to separate as the standard, the common 5KG or so. Drop test to the usual desktop height drop to the hard floor without damage as the standard.
3. After the button strength: the use of the powder box, the button part of the lever because of the principle of large and most vulnerable damage, the strength of the button is a very important function. Taking into account the impact of cosmetics on this area, usually after the button strength to apply material testing.
4. Decorative Adhesion: General tape test, test tape with 3M600, 3M810, 3M616, NICHIBAN and other root different customer requirements (EL with 3M810, L'OREAL with 3M616). Also for the bronzing / printing only tape testing, painting (plating, cover, etc.) to be lattice after the tape test.
5. Cover the bottom of the gap, the gap: commonly used standard ≦ 0.3mm, for different sizes of the powder box will have different standards
6. Cover any angle positioning: taking into account the use of the mirror when the convenience, usually require the lid to open between 45 ° -135 ° any angle can stop not fall.
- • Fit to the gap: cover the bottom in the mating position to leave enough clearance, common with the following:
- 1. The horizontal clearance of the rear button is not less than 0.15, if the coating is greater than 0.25.
- 2. The rear button rotation gap is not less than 0.3
- 3. The front button rotation gap is not less than 0.3
- Structural strength
- (Such as ABS, PCTA, etc.), the meat thickness of not less than 1.5; if the brittle material (AS, PS, PMMA, etc.), not the need for the strength of the button Less than 1.8, if the product to be plated or covered with light, the pinhole thickness to improve a grade, that is, ABS by AS operator.
- The strength of the front button, for better impact of the material, the former button thickness of not less than 0.8, if the brittle material is not less than 1.
- In addition to PL surface and the face, the product as far as possible rounded corners, so that not only improve the strength of components is also conducive to filling.
•
Pinhole design: pinholes try to design guide holes to avoid breaking when assembled. As far as possible designed to double the nail and ensure that the plastic parts and the needle with the length to meet the needs of the cover at any angle positioning.
