The pump head is one of the main container accessories in the cosmetic packaging materials. Its main function is to absorb the contents for application through cooperation with plastic bottles, glass bottles, hoses and other containers. Therefore, the quality of the pump head directly determines the consumer ’s The experience of this product mainly describes some basic quality elements of the pump head packaging material:

    

  1. 一. Basic requirements for surface appearance
  2. Smooth and complete, uniform thickness, no obvious skew, defects, defective parts
  3. Dirty / foreign objects: foreign objects cannot be removed, product contact area: can wipe away dirt and foreign objects, non-product contact area: can wipe away dirt and foreign objects
  4. Noise: No obvious color difference and noise point or noise line.
  5. The dust cover is well coordinated, not easy to fall off, no scratches, no mottling.
  6. Cloak / burr: Cloak and burr do not affect the use function, appearance and feel

  7. 二. Basic requirements of product and structure
  8. Gram weight: no more than 3% deviation of the weight
  9. Supporting: flexible rotation, moderate tightness; no slipping teeth. The gap between nozzle and bottle neck is ≤1.5mm.
  10. Straw: The length is appropriate and it is not easy to loosen.
  11. Number of pumping times: ≤5 times for liquid agent and emulsion; ≤10 times for cream.
  12. Ejection effect: The spray head needs to be in the form of mist, and the maximum range of the spray head and the indenter must be more than 1m.
  13. Weight: Generally according to the contract weight
  14. Size: contracted size
  15. Thickness: contracted thickness
  16. Printing / hot stamping adhesion: soak in water for 0.5h, ozone fumigation for 0.5h, UV irradiation for 1h, printing without falling off. 3M-810 / 3M-600 peeling test, the peeling area is less than 10%. Alcohol wipe test, the inner material is wiped for 1H, no obvious fall off
  17. Electroplating / spraying adhesion: ①3M-810 / 3M-600 hundred grid test, the shedding area is less than 10%. ② Alcohol wipe test, the inner material is wiped for 1H, and there is no obvious fall off.
  18. Coordination: The coordination is tight and smooth, without loosening or slipping.


 

  1. 三. Basic requirements of pump head function
  2. Sealing: The packaging material is packed with normal volume water of nominal capacity. The assembled packaging material is placed in a vacuum tester. The negative pressure is 0.08Mpa and the temperature is kept at 45 ℃ for 10 minutes. There should be no leakage. Vacuum tester A The packaging material contains normal temperature water with a nominal capacity, and there is no leakage when placed upside down or sideways for 24 hours.
  3. Pump output: the pump output is uniform and stable; the spraying effect of the nozzle is good, without obvious droplets
  4. Drop: Nominal capacity water is installed, and the 1.0 M level can be dropped freely without damage. It can be used normally after being separated from the components.
  5. Others: According to the contract or the design requirements of both parties
  6. Yellowing resistance: UV irradiation, 15cm, 48H. No obvious yellowing or fading.
  7. Micro-examination: the total number of colonies ≤500CFU / PCS, mold and yeast≤50CFU / PCS.
  8. Heavy metal: It conforms to the 2007 edition of the Cosmetic Hygiene Code.
  9. Prohibited substances: comply with domestic and foreign laws and regulations.
  10. Material: conform to the specified material
  11. Heat resistance: The packaging material is placed in a 45 ° C incubator for 48h. After the room temperature is restored, all the tests are repeated. The test results must be consistent with those before the heat resistance test, and it is judged as qualified.
  12. Cold resistance: The packaging material is placed in a freezer at -5 to -10 ° C for 48 hours. After the room temperature is restored, all the tests are repeated. The test results must be consistent with those before the cold resistance test.
  13. Compatibility: Install the corresponding inner materials, heat-resistant (45 ± 1 ℃) and cold-resistant (-5 ~ -10 ℃ —) alternately measured for 14 days, the inner materials and the packaging materials will not react
