Capsule Bottle HDPE CFB-25
Plastic Capsule bottle external shapes of medical HDPE bottles are round, square and oval. The application of round bottle body is the largest, especially for the bottle body with a capacity of 15ml to 200ml. It is characterized by uniform wall thickness, high ability to absorb external impact energy, low production cost, and low utilization rate of effective area during storage or transportation. The square bottle has high utilization rate of effective area and good stability, but it is prone to bulging deformation. Elliptical bottles are the least used in drug packaging, but more used in cosmetic packaging. Due to the large amount of HDPE bottle, the shape is beautiful. It is suitable for the packaging of drug solid dosage form, and its bottle shape design has its own characteristics. The design of round bottle mouth, bottle neck shoulder, bottle body and bottle bottom is reasonable and has some characteristics. First, in order to facilitate the mechanical charging of tablet and capsule solid dosage forms, the design of bottle mouth diameter usually considers the single volume of drug and appropriate space. The cross section of the thread shape at the neck of the plastic bottle is mostly semicircular. From the outside, it is fine thread with two ends. There are also trapezoidal threads, which are called single thread. The shape design of the screw thread at the neck of the bottle mouth mainly depends on the good compatibility of the bottle cap, because the moisture resistance of the drug packaging largely depends on the fit between the bottle mouth and the bottle cap and the tightness after applying torque. Here is the main part reflecting whether the sealing performance of the bottle mouth is excellent or not. The original design is that there is a sealing gasket in the bottle cap and an anti-theft cap is used outside. This anti-theft cap can provide visible traces of seal damage. Its structure is mainly that there are a circle of small holes around the bottle cap along the bottom of the side skirt to form a broken line. When the bottle cap is twisted, because the wave flanging pawl is tightly locked under the convex ring at the lower end of the bottle mouth, the reverse rotation bottle cap can break along the folding line and the lock ring. At present, the plastic bottle mouth is sealed by electromagnetic induction with aluminum foil gasket, which has the properties of moisture-proof, sealing and anti-theft at the same time, so it is unnecessary to use the form of anti-theft cap. Secondly, from the design of bottle neck and bottle shoulder of HDPE, longitudinal dissection of bottle section shows that bottle neck and bottle shoulder are composed of two tangent arc radii, which are divided into two segments from the tangent point. The distance between the bottle neck and the center line, shoulder radius and neck arc radius should be calculated, and the total height between the bottle neck and the bottle shoulder should be obtained. The main factor affecting the strength of the bottle shoulder is the inclination angle of the bottle shoulder. When the bottle shoulder is too flat, the bottle body is prone to collapse. Therefore, when the length of the bottle shoulder is 10 mm, the inclination angle of the shoulder should be more than 15 degrees, and the thickness of this part should not be less than 1 mm, so as to ensure that the bottle body does not have shoulder fracture during the process of holding and storing drugs and using. Third, the bottle body of HDPE bottle is a cylindrical circular revolving body. The requirement for the bottle body is that the wall thickness is uniform. If the bottle wall is too thick, the weight of the bottle body will increase, the consumption of raw materials will increase, the internal stress of the bottle will increase, and the shrinkage will also increase. If the bottle wall is too thin, it is difficult to blow molding and the strength is low. -The general requirement is that the wall thickness of other parts should be uniform except that the reinforcement, rib and thread of the bottle mouth are thicker than that of the bottle body. In order to improve the barrier and strength of plastic bottle, the thickness of bottle body is generally 1.2-1.5mm. The design of the bottom of plastic bottle adopts concave bottom or flat bottom with double rounded corners. Concave bottom means that the bottom of the bottle is concave into the bottle to form an arch, which can enhance the anti internal pressure ability of the bottle and ensure the stability of the bottle. The concave bottom can also avoid plastic collapse and make the thickness of bottle bottom uniform during blow molding. The flat bottom and double rounded bottom structure is mostly suitable for large volume bottle bottom, which can better withstand the internal pressure.
