Lipstick is the general term for all lip makeup. Lipstick tube with different length to mark different capacity characteristics, capacity 3ml-360ml can be adjusted, for the sake of beauty and coordination, 60ml below commonly used 35# below caliber, 100ml, 150ml usually used 35# - 45# caliber, 150ml above the capacity needs 45# above caliber. Lipstick (b ā o kuo) lip gloss, lip stick, lip gloss, lip glaze (you), etc., can make the lips ruddy luster, to moisturize, protect lips (lip), facial beauty and amended lip contour have foil effect of a Product (Product), and for the lipstick products (Product) be forgotten the lipstick tube packaging material, because of complex structure and function, and quality is also more difficult to handle. Therefore, the structure quality requirements of cosmetic packaging material lipstick tube are as follows:
A,Basic structure requirements of the lipstick tube
1. Material quality: materials determined in the contract between the parties shall be processed, and improper raw materials and Produce shall not be used for installation. Emulsion pump specifications range from 16ml to 38ml, the water output is 0.28ml/ time -- 3.1ml/ time, generally used for cream and washing products.
2. Dimension: tube height dimension deviation ≤0.1mm; Fit with the outer cover under proper torque, the outer cover buckle smoothly, and the gap between the outer cover and the tube ≤0.1mm. The size of the bead (bead, fork, screw) shall be in accordance with the design and sealing sample size.
3. Weight: the weight confirmed by both parties or the sealed sample shall prevail.
Second, the structure of the lipstick tube
1. Opening tension of cover/bottom: the opening force should be between 0.2 ~ 2 kg (between 1.96N ~ 19.6N). Emulsion pump specifications range from 16ml to 38ml, the water output is 0.28ml/ time -- 3.1ml/ time, generally used for cream and washing products.
2. Pull out force of the middle beam and the base: should ≥ 4kg force (39.23n).
3. Rotating torque: the rotating torque should be between 0.1n.m and 0.5n.m, and there should be no obvious sound caused by too tight rotation. If the sliding wire is generated after the rotation to the bottom, the sliding wire torque should be ≥ 0.4n.m.
4. Middle beam: rotate the base, and the middle beam shall not be eccentric (after loading, the rotating base will cause the material body to scratch).
5. Fitting of pipe cover: compared with the sealing sample, the fitting of pipe and cover is allowed to have a tolerance of 0.5mm. The caliber of pipe mouth and the production mold (title: the mother of industry) must be matched moderately.
