In order to provide a variety of tastes for users, sometimes different substances must be mixed to prepare a mixture, for example, coffee drinks can be mixed with sugar or cream in the bottle cap; the additive separation plays an important role in protection of some ingredients to prevent deterioration and keep the taste of some food, and can also greatly improve the overall shelf life. Similarly, it can be applied to drugs and chemicals.
  • In order to mix two substances, users must purchase two bottles to accommodate two substances, especially when the substances must be mixed in strict proportion, users must use a measuring implement to prepare the mixture; if there is no such measuring implement, it is hard to keep the correct proportion of the mixture, making the mixture incorrectly, even unable to use.
  • Therefore, in order to overcome the above problems, a bottle cap with additive separate from the bottled material is put forward. The majority of existing bottle caps with additive are complex in structure, high in cost and inconvenient in operation; after adding the additives to the bottle, the sealing performance of the whole bottle is compromised; the sealing piece for packaging the additives may fall into the bottle.
  • For the majority of bottle caps with additive, the additives and the bottled material are separated through closing two block pieces, the airtight integrity is poor, the bottled material may permeate into the additive after lengthy inversion.

  • The thickness of the bottom of the second outer skirt part 6 is smaller than that of the upper part of the second outer skirt part , and the bottom of the second outer skirt part 6 is named as the knocking part 16. The thickness of the knocking part 16 is smaller than that of other parts of the second outer skirt part 6 so that there is sufficient acting force applied to the crackable part 10 when pressing the storage cap 2 to ensure that all parts on the edge part 12, except for the thickened part 13, can be cracked by the applied pressure.
  • There is a cavity 18 fit to the upper part of the bottle and arranged between the first outer skirt part 5 and the second outer skirt part 6, the internal threads 17 that fit to the bottle are arranged in the first outer skirt part 5, external threads are arranged on the bottle, and the bottle is connected to the bottle cap body 1 through the threads.
  • During installation, additives are put into the storage cap 2, the second outer skirt part 6 is clamped into the mounting groove 8, the inside of the groove wall 9 is fit to the periphery of the second outer skirt part 6, the bottom of the groove wall 9 is positioned above the crackable part 10, the upper part of the storage cap 2 is exposed above the bottom of the step hole 7, at that time, the annular boss 20 is clamped into the annular groove so as to seal the interior of the storage cap 2 to avoid contamination of the additives. In use, the storage cap 2 is knocked downward forcibly, and the edge part 12 of the crackable part 10 is impacted by the lower end of the second outer skirt part 6; since the crackable part 10, the thickened part 13 and the second outer skirt part 6 are all made of plastic of certain elasticity, after the thickening part 13 is impacted by the knocking part 16, the thickened part 13 is squeezed to continue transferring the pressure to the thin edge part 12 of which the thickness is 0.01-0.5 mm only, so the thin edge part 12 can be cracked completely by the acting force produced by the downward displacement of the storage cap 2; after being moved downwards and abutted against the bottom of the step hole 7, the annular flange 14 stops moving, the step hole 7 plays a role in preventing the annular flange 14 from moving downwards and the thickened part 13 from being cracked by the continuous downward displacement of the annular flange 14. The additives fall into the bottle and mix with the bottled material. The thickened part 13 will not be cracked by the second outer skirt part 6 due to its greater thickness so as to ensure that the crackable part 10 can not fall into the bottle to affect the bottled material. After the crackable part 10 is impacted by the second outer skirt part 6, the annular flange 14 is clamped into the step hole 7 so as to make the bottle cap body 2 remain a sealed structure; when shaking the bottle, the bottled material will not leak out of the bottle cap body 1.
  • In a word, the above mentioned content is the optimal embodiment of the invention. All equivalent changes and modifications made according to the claims of the invention shall belong to the scope of the invention.
