The present invention relates generally to a medicine bottle having a solid silica flaky drying agent, in the technical field of pharmaceutical packaging.
Medicine, as a kind of special merchandise related to human health, has special security requirements for every step of manufacturing, packaging, transportation and using, wherein the requirements for drying agent in packaging step are even more critical. The drying agent currently used in this industry is medicinal silica gel drying agent, using solid paper packaging or plastic vials packaging with numerous small holes. The silica gel is non-degradable, and has poor plasticity and, therefore, the packaging and bottling can not depart from human hand (the drying agent is first placed into a packaging bag or a bottle firstly, and then the packaged drying agent is put into a medicine bottle, requires two production processes). It is well known that, hand contact is likely to cause secondary pollution, and leave a small amount of crumb. The silica gel drying agent has a poor moisture absorption capacity, especially at 99% relative humidity. Its absorption saturation is reached only in 24 hours and the silica gel loses effectiveness.
In this regard, a Chinese utility model No. 200710094046.4, entitled “silicon oxide drying agent and the production method thereof” discloses a solid silica flaky drying agent comprising of 80-85% silicon oxide power and 15-20% starch. This product uses natural silica as raw material, which is non-toxic, odorless, and has a strong moisture absorption capacity; there is no change in color, no deliquescence and no pollution after moisture saturation. The significant advantages of this solid silica flaky drying agent, as compared with other drying agent, are: lasting moisture absorption effect, balanced moisture absorption rate, thus ensuring the quality of medicines. The compressive strength of the solid silica flaky drying agent is good, and there is no crumbling, no dust. Furthermore, the drying agent is sealed in a filter paper packaging, preventing a direct contact between the drying agent and the medicine, and greatly reducing the pollution source of dust particle and microbial contamination. However, due to the similar shape of the solid silica flaky drying agent and the medicine, putting the drying agent and the medicines together could easily lead to erroneously intake by senior citizens and children.
The present invention provides a medicine bottle with a solid silica flaky drying agent. Using the medicine bottle of the present invention can effectively prevent erroneous intake by senior citizens and children, and improve the safety in the use of medicine.
The present invention, by reducing the packaging link and making the packaging process in one step, enables the safety, effectiveness and homogeneity of the medicine. Compared with the existing pharmaceutical packaging technology (placing the drying agent into a packaging bag or a bottle, then putting the packaged drying agent into a medicine bottle, two production processes are required), the present invention reduces a production process, thus greatly increasing labor productivity and improving labor intensity and conditions.
The medicine bottle of the present invention includes a bottle cap in which a bottle cap screw thread is provided and a bottle body, a bottle body screw thread which can match with the bottle cap screw thread is provided on the outside of upper portion of the bottle body, the structural features are that: a circular bottle cap locking notch is provided between the bottle cap screw thread and the inner top end of the bottle cap, a bubble cap-type solid drying agent is installed between the circular bottle cap locking notch and the top of the bottle cap; or a circular bottle body locking notch is provided on the lower end of the bottle body, and a bubble cap-type solid drying agent is installed between the inner bottom end of the bottle body and the circular bottle body locking notch.
The bubble cap-type solid drying agent comprises a solid silica flaky drying agent, a tea filter paper, a bubble cap baseplate and a bubble cap, and moisture absorption openings from inside to outside; the moisture absorption openings penetrate the bubble cap, and the shape of the moisture absorption openings is circular or square, or triangular.

The shape and size of the bubble cap baseplate are compatible with the shape and size of the inner bottom end of the bottle body, while the thickness is consistent with the size of the gap between the inner bottom end of the bottle body and the circular bottle body locking notch, in order that the bubble cap-type solid drying agent is locked, so that it will not loose and fall off.
The solid silica flaky drying agent is a silicon oxide drying agent formed by 80-85% silicon oxide power and 15-20% starch by weight through mixing uniformly, sieving, pressing into tablets and drying.
The present invention includes the following advantages:
1. Because the medicine bottle of the present invention is configured such that the solid silica flaky drying agent is installed in the bottle cap or on the bottom end of the bottle body, and the solid silica flaky drying agent is fixed by the bottle cap ring-shaped locking notch or the bottle body ring-shaped locking notch, thus having an effect of being retained in the bottle, and will not be erroneously taken as medicine by the elderly or children.
2. The present invention uses a solid silica flaky drying agent, a filter paper, a bubble cap baseplate and a bubble cap to form a bubble cap type solid drying agent, and thus good drying effect can be guaranteed. In addition, the solid drying agent has better compressive strength, no crumbling, no dust, and the bubble cap prevents the direct contact between the drying agent and the medicine, and thus greatly reducing the potential danger of pollution source of dust particle and microbial contamination to the medicine.
3. The solid drying agent of the present invention is produced by using natural silica as a raw material, so it is non-toxic, odorless, and has a strong adsorption capacity as compared to the existing silica gel drying agent. It has the advantages of no change in color, no deliquescence and no reverse osmosis after moisture saturation, lasting moisture absorption effect and uniform moisture absorption rate, etc.
4. The present invention uses a method of creating moisture absorption openings on the bubble cap, ensuring the dryness of the medicines in the bottle, and the duration of drying lasts long, with the saturation time of absorption more than seven days at 99% relative humidity (the saturation time of absorption of the existing drying gel is only one day, 24 hours at 99% relative humidity), therefore providing a reliable guarantee for making the packaging process into one step, that is fully automated packaging.
5.
