Definitions

• the present invention relates to a bottle cap made of a synthetic resin, which is attached to a mouth portion of a container, such as a PET bottle, and which stores therein an ingredient to be mixed, upon opening of the bottle, with a liquid content in the bottle body.
• the present invention provides a bottle cap, which comprises a cylindrical body to be attached to a mouth portion of a bottle, and providing a passage to communicate with an interior space of the bottle, and further comprising a lid body detachably attached to the cylindrical body, for closing an outlet end of the passage of the cylindrical body.
• the passage of the cylindrical body is provided with a dome-shaped bottom wall having a peripheral portion that projects towards the outlet end of cylindrical body.
• the lid body has a top wall and an inner wall adapted to surround and fit with a peripheral portion of the bottom wall, thereby forming a closed chamber within the cap for storing an ingredient to be mixed with a content in the interior space of the bottle, wherein said chamber is opened when the lid body is detached from the cylindrical body.
• the dome- shaped bottom wall has spokes for supporting and fixing the bottom wall to an inner wall of the cylindrical body, while maintaining the passage so that the passage can communicate with the internal space of the bottle.
• the closed chamber of the bottle cap according to the present invention serves to store the ingredient either alone or together with an inert gas.
• the bottom wall is fitted with the inner wall by an undercut.
• the bottle cap according to the present invention has a simple two- parts structure, comprised of a cylindrical body for sealing the mouth portion of a bottle and forming a ingredient storing chamber in cooperation with the dome- shaped bottom wall, and a lid body for covering the cylindrical body. Moreover, since the ingredient is supplied through a gap between the cylindrical body and the lid body into the interior space of the bottle and mixed with the content therein, the risk of any one component falling into the interior space of the bottle can be positively avoided upon opening of the ingredient-storing chamber.
• FIG. 1 is a sectional view of a bottle cap according to a preferred embodiment of the present invention.
• FIG. 2 is a bottom view of the bottle cap of FIG. 1 depicting the major components of the bottle cap.
• FIG. 3 is an explanatory view showing the ingredient as being added to, and mixed with the content in the bottle.
• FIG. 4 is an explanatory view showing how to pour the mixture from the bottle.
• FIG. 5 is an explanatory view showing how to charge the ingredient into the ingredient-storing chamber of the bottle cap.
• FIG. 6 is a sectional view of a bottle cap according to another embodiment of the present invention.
• reference numeral 1 denotes a cylindrical body of a bottle cap according to the present invention, which is threadedly attached to the mouth portion of a bottle.
• the cylindrical portion 1 has passages Ia communicating with the interior space of the bottle, when the cap is attached to the bottle.
• Reference numeral 2 denotes a lid body of the bottle cap, which is detachably attached to the cylindrical body 1 in appropriate manner, e.g., by a thread connection or by an undercut. When the lid body 2 is attached to the cylindrical body, the lid body 2 closes the outlet ends of the passages Ia of cylindrical body 1.
• Reference numeral 3 denotes a dome-shaped bottom wall provided at the center of the passages Ia in the cylindrical body 1.
• the bottom wall 3 has a peripheral region that projects toward the outlet end of cylindrical body 1.
• the bottom wall 3 is fixed to the inner wall of the cylindrical body 1 via supporting spokes 3a, which not only support the bottom wall 3, but also maintain the passages Ia.
• Reference numeral 4 denotes a cylindrical inner wall integrally constructed with the lid body 2.
• the inner wall 4 has an undercut to be fittingly engaged with the peripheral region of the bottom wall 3, such that a closed chamber M is formed within the lid body 2, for storing an ingredient to be added to the liquid content within the bottle body.
• the liquid content in the bottle body and the ingredient to be added to the liquid content for mixture are strictly separated from each other, so as to stably maintain the quality of the ingredient.
• the bottom wall 3 has a dome-like shape with the peripheral region projecting toward the outlet end of the cylindrical body, as shown in the figures, the ingredient stored in the chamber M is allowed to rapidly fall down along the slope of the bottom wall 3, as soon as the gap is formed between the inner wall 4 and the bottom wall 3.
• the lid body 2 is again threadedly connected with the cylindrical body 1 tightly, so as to allow an intensive shaking of the bottle body until the ingredient is fully mixed with the liquid content to give a uniform mixture.
• the cylindrical body 2 together with the lid body 3 is removed from the mouth portion of the bottle. It is now possible to pour from the bottle the uniform mixture obtained by dissolving the ingredient to the liquid content.
• the lid body 2 is inverted as shown in FIG. 5, so that the ingredient can be charged into a cavity defined by the inner wall 4 and the top wall. Then, while maintaining the lid body 2 in the illustrated orientation, the peripheral region of the dome-shaped bottom wall 3 is fitted with the inner wall 4 of the lid body 2. [0026] It is possible to fill the ingredient storage space M with an inert gas to prevent oxidation of the ingredient. Whether the ingredient is stored a solid, powder or liquid may be determined as appropriate, and the ingredient can be readily introduced into the space regardless of its selected physical form.
• the dome-shaped bottom wall 3 is fixed to the sidewall of the cylindrical body 1 via four supporting spokes 3a. It is of course that the number of supporting spokes 3a is not limited to four but may be more than four or fewer than four as needed, as long as the supporting arms do no interfere with the passage of the ingredient.
• the components of the bottle cap may be made of a polypropylene resin, but the material is not limited to any specific one.
• FIG. 6 Another embodiment of the bottle cap according to the present invention is shown in FIG. 6.
• the top surface of the lid body 2 covers the edge of the mouth of cylindrical body 1 and seals it by sandwiching the edge from both inside and outside.
• a virgin ring 5 is provided for the joining section between the cylindrical body 1 and the lid body 2
• another virgin ring 6 is provided for the joining section between the cylindrical body 1 and the mouth portion of the bottle, so as to allow detection or prevention of fraudulent opening of the bottle, if any.
• the present invention provides an ingredient-containing bottle cap of a two-parts structure with minimized number of components, and serves to positively avoid falling of any component when the ingredient is added to the liquid content in the bottle for mixture.
