TECHNICAL FIELD
[0001] The utility model relates to the field of medicine packaging, in particular to a novel medicine plastic bottle. BACKGROUND
[0002] In the field of medicine packaging, the traditional part of the medicine bottle has the problem of poor sealing. Many medicine bottles adopt a simple screw cap design, and the sealing between the cap and the bottle body only relies on the engagement of the threads. In actual use, for example, during transportation or long-term storage, external air can easily enter the bottle through the small gap between the cap and the bottle body, and after opening and closing multiple times, the sealing performance will gradually decrease, which can easily cause the medicine to be oxidized or damp, thereby affecting the drug efficacy.
[0003] In addition, these medicine bottles usually do not have precise dose control function, and patients often have difficulty in controlling the amount of medicine poured out when pouring medicine, especially for the elderly with less flexible hands and feet, who may pour out half of the medicine at once, then count and put the medicine back into the bottle, which can cause the medicine to be contaminated by hand bacteria, affecting the safety of the medicine. At the same time, the cap may also fall off or fall off and be difficult to pick up, and the medicine will be exposed to the external environment, which can not only cause contamination, but also accelerate the deterioration of the medicine. The above problems not only affect the patient's experience of taking medicine, but also pose a potential threat to medical safety. Therefore, it is of great significance to develop a medicine packaging container with improved sealing, quantitative pouring of medicine, and cap not easy to fall off, to improve the convenience and safety of medicine use.
