Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an additive container and more particularly, to a bottle cap type additive container that is connectable to a mineral water bottle to improve the flavor (and/or appearance) of the mineral water.

2. Description of the Related Art

Various different types of beverages including juices, mineral water, teas, herbal teas, and etc., are available on the market. Except mineral water, most packed commercial beverages contain a preservative. It is not healthful to drink a beverage containing a preservative. Further, different beverages provide different tastes. For different tastes, a consumer may have to purchase various different beverages. However, it is inconvenient to carry and store a number of packed beverages.

SUMMARY OF THE INVENTION

The present invention has been accomplished under the circumstances in view. It is one object of the present invention to provide a bottle cap type additive container, which is connectable to a mineral water bottle to improve the flavor (and/or appearance) of the mineral water. It is another object of the present invention to provide a bottle cap type additive container, which keeps the additive fresh for long. It is still another object of the present invention to provide a bottle cap type additive container, which uses a preservative-free additive to improve the labor and/or appearance of the drinking water of a water bottle.

To achieve these and other objects of the present invention, the bottle cap type additive container comprises a cylindrical container body, an insert, and a sealing film. The cylindrical container body has an inside chamber, a water-soluble food grade additive filled in the inside chamber, and an inner thread spirally extending along the inside wall near the bottom open side for threading onto the threaded neck of a bottle. The insert is inserted into the bottom open side of the cylindrical container body to seal the water soluble food grade additive inside the cylindrical container body, having an annular base and a filter element mounted within the annular base for allowing passing of a fluid in and out of the inside chamber of the cylindrical container body and filtering the fluid passing therethrough. The sealing film is sealed to the bottom open side of the cylindrical container.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1-3, a bottle cap type container in accordance with a first embodiment of the present invention is shown comprising a cylindrical container body 1, an insert 13, and a sealing film 134.

The cylindrical container body 1 has an inside chamber 11, which holds a food grade additive A, an inner thread 121 spirally extending along the inside wall near the bottom open side, an inside annular stop 12 protruded from the inside wall above the inner thread 121. The insert 13 has an annular base 131, a filter element, for example, a filter cloth 132 stretched on the annular base 131, and a pointed tip 133 extended from the bottom side of the annular base 131. After the prepared food grade additive A has been filled in the inside chamber 11 of the cylindrical container body 1, the insert 13 is inserted into the bottom open side of the cylindrical container body 1 with its annular base 131 stopped at the inside annular stop 12 to seal the food grade additive A inside the cylindrical container body 1, and then the sealing film 134 is sealed to the bottom open side of the cylindrical container body 1, keeping the cylindrical container body 1 in an airtight status. When assembled, the pointed tip 133 faces the sealing film 134. Further, the food grade additive A is a water-soluble substance to be added to a drinking water to improve flavor or appearance. The food grad additive A can be a flavor additive, Chinese medicine additive, nutrient substance, solid

Referring to FIGS. 2 and 3 again, when in use, the screw cap 21 is removed from the threaded neck 211 of the mineral water bottle 2, and then the sealing film 134 is detached from the cylindrical container body 1, and then the inner thread 121 of the cylindrical container body 1 is threaded onto the threaded neck 211 of the mineral water bottle 2 to pierce the pointed tip 133 through the top sealing film 22 of the mineral water bottle 2, and then the mineral water bottle 2 is turned upside down or shaken to have the mineral water go through the filter cloth 132 to dissolve the food grade additive A, thereby improving the flavor (and/or appearance) of the mineral water.

FIGS. 4 and 5 show a bottle cap type container in accordance with a second embodiment of the present invention. According to this second embodiment, the bottle cap type container is comprised of a cylindrical container body 1, an insert 14, and a sealing film 144. The cylindrical container body 1 has an inside chamber 11, which holds a food grade additive A, an inner thread 121 spirally extending along the inside wall near the bottom open side, an inside annular stop 12 protruded from the inside wall above the inner thread 121. The insert 14 has an annular base 141, and a filter cloth 142 stretched on the annular base 141. After the prepared food grade additive A has been filled in the inside chamber 11 of the cylindrical container body 1, the insert 14 is inserted into the bottom open side of the cylindrical container body 1 with its annular base 141 stopped at the inside annular stop 12 to seal the food grade additive A inside the cylindrical container body 1, and then the sealing film 144 is sealed to the bottom open side of the cylindrical container body 1, keeping the cylindrical container body 1 in an airtight status.

Referring to FIGS. 4 and 5 again, when in use, the screw cap 21 is removed from the threaded neck 211 of the mineral water bottle 2, and then the sealing film 144 is detached from the cylindrical container body 1, and then the inner thread 121 of the cylindrical container body 1 is threaded onto the threaded neck 211 of the mineral water bottle 2, and then the mineral water bottle 2 is turned upside down or shaken to have the mineral water go through the filter cloth 142 to dissolve the food grade additive A, thereby improving the flavor (and/or appearance) of the mineral water.

Although particular embodiments of the invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention.
