Drug packaging container drum design (below)

4.5.1 Appearance inspection: The visual inspection of the drums mainly includes sealers, lids (bottoms), barrels, adhesives, printing, etc. The inspection methods include sensory inspection and gauge inspection.

1 The sealer is the main part of the paper drum. The cohesion, opening flexibility, interchangeability and fit with the barrel directly affect the quality of the packaging. Therefore, sealers must be used several times during inspection. Opening and closing of the mouth of the drum.

2 barrel test, no mechanical abrasion on the outer surface of the barrel, barrel round, no obvious round, dent, skew, wrinkle-free, no open plastic, uniform coating, no leakage, no bubble no Obvious sag, paper barrel round curled paperless. The barrel diameter should be measured in the direction of the conjugate diameter of the upper and lower faces of the cardboard drum.

3 The inspection of the lid (bottom) mainly includes the use of materials and size detection: the lid (bottom) is required to use penta-panel or other equivalent material, but it is not allowed to be spliced. The cover (bottom) surface should be flat, no warping, no missing corners, no damage. The size of the lid (bottom) should be controlled within tolerance limits.

4 Carton binder. The adhesive agent used in the production process of the carton is PVA octyl water-soluble adhesive. It is mainly used for the bonding of main materials and fiber materials. It is not allowed to use adhesives that contain toxic and migration pollution.

5 Printing: The appearance of the printed content mainly includes the product name, origin, batch, weight (net weight, gross weight), taro marks, clear and even printed characters, solid attachment, no running ink.

The inspection of the barrel body and the inside of the barrel requires that there is no defect in the barrel body seal, no burr, and no slag in the barrel.

4.5.2 Performance check of drums: There are two performance tests for drums: drop test and stacking test.

1 Drop test: The sample is subjected to temperature and humidity pretreatment: the temperature is 20±2°C, the temperature is (65±5)%, and the time is 48 hours. The barrel should be filled with dry sand and sawdust mixture to reach 95% of the specified maximum containing quality and volume. Closed, the temperature and humidity of the mixture is consistent with the sample pretreatment conditions.

There are two drop test technical parameters: number of tests (6) and drop height (0.8 m). Test method: The pre-treated sample is lifted to a predetermined height with the test equipment. After stabilization, the shedding device is started to make the sample perform a free-fall motion instantaneously. Each piece of palm is dropped once. When dropping, first, each bucket should be made Any point on the bottom edge collides with the ground, and then the point on the top edge of each bucket that is adjacent to the handle of the closure collides with the ground. After the test is completed, check whether the lid (bottom) is peeled off and whether the contents are spilled.

2 stacking test

This test is carried out to simulate the stacking and stowage requirements of the package during actual storage. There are 3 stacking samples and the stacking height is 3 meters.

Test method: Put the sample on the stacking ground, place the load plate at the center of the top surface of the sample, and then place the weight on the load plate without causing impact, so that it is evenly contacted with the load plate. The total weight of the weight and the load plate and the specified value should be controlled within ±2%. The stacking load is 4900N. No leakage or cracking occurs in 24 hours. Permanent deformation should not affect the stacking capacity of the drum.
