  • a coffee-based beverage may be mixed with sugar or cream therein; medicines and chemicals are similar cases.
  • a bottle cap which contains an additive different from a bottled material has been proposed.
  • the bottle cap containing an additive is problematic in that the additive storage space of the bottle cap is exposed to the atmosphere or does not maintain a desired seal.
  • the fluidities of some additives contained in the bottle caps may change in accordance with variation in atmospheric temperature.
  • the seal of a bottle cap closely relates to changes in the quality and properties of an additive during long distance transportation of products and long-term storage of the products in changing seasons.
  • the seal structures of additive storage spaces of bottle caps have been actively studied.
  • a first object of the present invention is to provide a bottle cap which contains in an isolated additive storage space thereof an additive to be mixed with a bottled material, and opens the additive storage space simultaneously with an opening action thereof as desired, thus easily discharging the additive into the bottle body.
  • Another aspect of the first object of the present invention is to provide a bottle cap which maintains the desired seal on the additive storage space containing therein the additive, thus withstanding a change in inner pressure of the additive storage space, and preventing a change in quality of the additive during long-distance transportation or long-term storage of products, and, furthermore, preventing vapor or gases generated from a bottled material from being introduced into the additive storage space.
  • the present invention provides a bottle cap comprising: an opening unit inserted into the mouth of a bottle body and open at upper and lower ends thereof, with a cutting unit integrally provided in a lower portion of the opening unit; an additive storage container comprising a main cap fastened to the mouth through a screw-type engagement, and an additive storage part extending in an axial direction at a position inside the main cap and being inserted into the opening unit, with a recess provided at the lower end of the additive storage part and receiving therein the cutting unit, and a breakable part integrated with the lower end of the additive storage part such that the breakable part is cut by the cutting unit during rotation of the additive storage part, thus discharging an additive from the additive storage part; and an upper cap which opens or closes the upper end of the additive storage container.
  • a second object of the present invention is to provide a bottle cap which causes breakage of a locking ring simultaneously with a rotating action of an additive storage container, thus allowing a user to conveniently use the bottle cap.

  • a locking ring is coupled to a lower end of the main cap with a breakable line provided between the locking ring and the main cap, the locking ring being restricted from moving downward by an upper surface of a support ring which is formed around the outer circumferential surface of a lower portion of the mouth.
  • An annular space is defined between the locking ring and the outer circumferential surface of the mouth, thus allowing the main cap to be inserted into the annular space.
  • a fourth object of the present invention is to provide a bottle cap which is configured such that an outer cap and an opening unit can be removed from the mouth of a bottle body at the same time after an additive has been discharged, thus realizing a desired cutting structure and a desired sealing structure which may not be provided in a conventional structure to discharge the additive without using an isolating means.
