Medicine bottle with solid silica flaky drying agent

Abstract

A medicine bottle with a solid silica flaky drying agent is disclosed. The solid silica flaky drying agent is wrapped in a filter paper and packed inside a bubble cap on which a number of holes are provided for moisture absorption. The bubble cap containing the solid silica flake drying agent can be attached to the cap of the medicine bottle via a baseplate behind a circular locking notch for preventing the solid silica flake drying agent from falling off the cap, or placed at the bottom of the medicine bottle which has a circular locking notch to prevent the solid silica flake drying agent from falling out of the medicine bottle.

DETAILED DESCRIPTION OF THE INVENTION

(8) Referring to FIGS. 1-5, based on the 5 ml to 5 l capacity of a circular or rectangular medicine bottle, estimate the amount of the solid silica flaky drying agent being 0.5-500 g. Then, in accordance with the content of Chinese patent application entitled “silicon oxide drying agent and the production method thereof”, No. 200710094046.4, mix 80-100 g of commercially available silicon oxide power with silica sol in a weight ratio of 1:0.8-0.9 to obtain a mixture, and then mix the mixture with starch in a weight ratio of 4-4.25:0.75-1; add mold-release agents magnesium stearate containing the magnesium stearate in an amount of 0.5˜1% of the total weight of the mixture. After screening the final mixture and compressing it into tablets, oven-drying the tablets and vacuum treatment, the solid silica flaky drying agent 4 is obtained.

(9) The solid silica flaky drying agent 4 is wrapped with a tea filter paper 3, which is produced by Zhejiang Hangzhou Xinhua Paper Industry Co., Ltd. or Zhejiang Puruike Special Paper Co., Ltd. and meets the pharmaceutical use requirements with the specifications of 10-50 g/M2.

(10) Then hot-press the solid silica flaky drying agent 4 wrapped by the tea filter paper 3 integral with the PE film by using a DPT-190 bubble packaging machine produced by Jinzhou Aluminum Plastic Machinery Co., Ltd, obtaining a bubble cap type solid drying agent. Specific pressing processes are as follows: press-form the PE film that is used to make the bubble cap in accordance with the hot-pressing temperature of PE to obtain bubble cap 5; perforate four symmetric moisture absorption openings around the circumference of the bubble cap 5; put the solid silica flaky drying agent 4 wrapped by the tea filter paper 3 into the space in bubble cap 5; thereafter, cover the bubble cap 5 with bubble cap baseplate 1 for heat-sealing and pressing to obtain the bubble cap type solid drying agent.

(11) The bubble cap baseplate 1 is a medical paper-plastic PE baseplate produced by Shanghai Yate Yingyi Packaging Material Co., Ltd. The shape and size of the bubble cap baseplate 1 is compatible with the shape and size of the inner top end of the bottle cap, 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 (12) or compatible with the shape and size of the inner bottom end of the bottle body. The shape and size of the bubble cap baseplate 1 is compatible with the shape and size of the inner bottom end of the bottle body 10, 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 (12).

(12) The bubble cap 5 uses a PE film with the thickness specification of 100-500 μm produced by Hunan Qiyang New Wuzhou Packaging Co., Ltd. Firstly, opening four equidistant moisture absorption openings 2 in the connection of bubble cap 5 and bubble cap baseplate 1 with the size of the moisture absorption openings 2 being selected in the range of 1-50 mm depending on the size specification of the medicine bottle.

(13) In addition, adding a circular locking notch to the structure of bottle cap 6 and bottle body 9 in order to fulfill the requirement for mounting the bubble cap-type solid drying agent.

(14) Specific processes are as follows:

(15) The method of adding the circular bottle cap locking notch 7 to the bottle cap 6 is as follows: a circular projection is provided between the bottle cap screw thread 9 and the inner top end of the bottle cap 6, forming the circular bottle cap locking notch 7, the bubble cap-type solid drying agent is installed between the circular bottle cap locking notch 7 and the top of the bottle cap 6, so that the bubble cap-type solid drying agent will not fall off because of the circular bottle cap locking notch 7. Finally, the bottle cap 6 installed with the bubble cap-type solid drying agent, after sealing, is sent to a pharmaceutical packaging workshop for packaging the pharmaceuticals.

(16) It should be noted that the bottle body 10 has a circular projection which is used as the circular bottle body locking notch 12, and the bubble cap-type solid drying agent is installed between the inner bottom end of the bottle body 10 and the circular bottle body locking notch 12. The bubble cap-type solid drying agent will not fall off because of the blocking of the circular bottle body locking notch 12. Finally, the bottle body 10 installed with the bubble cap-type solid drying agent, after sealing, is sent to a pharmaceutical packaging workshop for packaging the pharmaceuticals.
