Cosmetic containers are packaging apparatus used for holding, storing and protecting cosmetics, and its function not only lies in the appearance presentation of the product, but also relates to the safety, sealing and use experience of cosmetics. Cosmetic containers for daily useinspection of goodsIt is a key link to ensure product quality, safety and user experience, and needs to be evaluated comprehensively in combination with appearance, functionality and other dimensions. The following areCosmetic container inspectionThe detailed criteria and methodology of the

One,Criteria for inspection of goods

1. Appearance inspection

surface quality: No scratches, bubbles, burrs, deformations, color differences, stains, blurred printing and other defects.

Printing/Logo: LOGO, label, lot number, capacity, etc. are printed clearly without peeling off and in accordance with the design draft.

color: Comparison under natural light source is consistent with the standard color palette, no color difference.

tightness: There are no leaks from the bottle top, pump head, cap, and other sealing areas.

2. Dimensional specifications

Key dimensions: Height, diameter, bottle threads, cap fit, etc. need to conform to design drawing tolerances (usually ±0.5mm).

quantitative (science): The actual filling volume needs to be the same as the nominal volume.

3. Material inspection

Material Certification: Suppliers are required to provide material reports (e.g. PET, glass, PP, etc.) that meet food-grade or cosmetic-grade standards.

Odor Test: The containers are free of irritating odors, and special attention should be paid to the plastic parts in particular.

4. Functional testing

On/Off: Lids, pump heads, spray valves, etc. open and close smoothly without jamming or leaking.

Pump head/spray effect: The number of presses is up to standard and the spray is even and drip-free.

Dropper/Scraper: The dropper draws liquid smoothly and the spatula has no burrs.

5. Packaging inspection

outer packaging: Cartons/pallets are undamaged and moisture-proof film is intact; containers are separated from each other by cushioning material to prevent transportation collisions.

Marking and Tracing: Manufacturing lot number, material symbol, and instructions for use are printed on the surface of the container. Verify barcode/QR code scanability and accuracy of information.

II. Methods of inspection

1. Sampling criteria

AQL level: Usually ISO 2859-1 Level II is used, e.g. 5000 containers, 200 sampled (as per AQL table).

2. Detection tools

Tools such as calipers, electronic scales, Pantone color cards, tape measure, and 3M tape.

3. Key test methods

Sealing test: Observe upside down after filling with water for fluid leakage.

volumetric testing: Measure the volume of water filled using a standard measuring cylinder.

Drop Test: A drop test is performed on a box filled with containers to check for product breakage.

III. Common blemish points

Misalignment of bottle top threads: Causes the cap to not tighten.

Poor print adhesion: Alcohol cotton wool wipes off the color.

Unstable liquid discharge from pump head: The average volume of fluid discharged from 10 compressions needs to be counted.

IV. Goods inspection reports

The inspection report should contain: product information, defect classification (Minor/Major/Critical), photos of defective products, judgment results (Pass/Fail) and other key information.

Through rigorous inspection of the above steps, the quality of cosmetic containers can be effectively ensured to avoid affecting brand reputation and consumer experience due to quality problems. During the actual inspection, you can adjust the focus of inspection by combining the characteristics of the product or the use scenario.Inspector OnlineProvision of specialized third-partyinspection serviceFor cosmetic container inspection, look forInspector OnlineWe are committed to ensuring the quality of your products!
