Title: Bottle

Description:
TECHNICAL FIELD  
      The present invention relates, in general, to a bottle equipped with a mixing means containing an additive and, more particularly, to a bottle equipped with a mixing means  
     BACKGROUND ART  
      For sale to general consumers, coffee drinks or carbonated beverages such as soda pop are stored in stores in closed containers such as cans, plastic bottles, and the like. Alternatively, the beverages are sold while being stored in open disposable containers at, for example, coffee shops or snack corners of theaters. Recently, a market for hybrid beverages, which combine one material with another different material, has been gradually growing in the world. In hybrid beverages, consumers may want to mix general beverages with different materials according to their tastes. For example, coffee with cream or ice cream is popularly sold. Also, people drink soda pop with ice cream added thereon.  
      Most beverage articles currently for sale, however, are difficult to apply additives to. Because the beverage articles displayed in markets have contents in closed containers, additives must be added externally in addition to being prepared separately. In the case of coffee shops, coffee, when ordered, is provided with ice cream in arbitrary amounts which are usually decided by the seller, but not by the customer. Thus, the customer may not be satisfied with the coffee drinks provided.  
      As for the coke float which is soda pop with ice cream added thereon, the ice cream mass floating on the soda is readily dissolved to form a milkshake-like beverage.

     BEST MODE FOR CARRYING OUT THE INVENTION  
      Reference should now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout. The embodiments are described below in order to explain the present invention by referring to the figures.  
      A bottle having a mixing means according to a first embodiment of the present invention is shown in an exploded cross sectional view of  FIG. 1  illustrating the entire structure, a cross sectional view of  FIG. 2  illustrating a combined state, and a plan view of  FIG. 3  illustrating a communication passage.  
      As seen in the figures, a bottle in accordance with the first embodiment of the present invention comprises a bottle body  100  having a mouth  110 , an adaptor  200  which is detachably inserted into the mouth  110 , an additive container  300  which is detachably combined with the adaptor  200  at one portion and has an open accommodation space  302  to contain an additive therein at the other portion, a communication passage which is adapted to communicate the accommodation space  302  via the adaptor  200  to the inside of the bottle body  100  or to prevent this communication using a screw-type engagement, a cover  400  which openably covers the additive container  300  at the open end and has at least one discharging port  430  through which the contents of the accommodation space  302  are drained, and a top cap  500  which openably closes the discharging port  430 .  
      The adaptor  200  comprises an outer cap  210  having negative threads on the inner side and an inner cap  220 , positioned inside the outer cap  210 , extending in an axial direction. The inner cap  220  is inserted into the mouth  110  by pressure and is provided with a communication hole  222  at the bottom. Also, the adaptor  200  is integrated with a connection portion  230  which extends from the outer cap  210  in the lengthwise direction and has a locking groove  232  around the inner circumferential surface thereof.  
      Constituting the additive container  300 , a cylindrical housing  304  provides the accommodation space  302  therein and protrudes at one end (bottom in the figure) to form a first protrusion  310 , with an open portion at the other end (upper portion in the figure). Provided to the bottom portion of the housing  304 , a first protrusion  310  is combined with the connection portion  230 , with a locking ring  312  formed around the external circumferential surface thereof. The locking ring  312  is locked into the locking groove  232 . Further protruding from the first protrusion  310  in the axial direction, a second protrusion  320 , which is configured to be inserted into the inner cap  220 , is integrally formed to have a smaller diameter than that of the first protrusion  310 . At the bottom of the second protrusion  320 , a drain hole  322  is formed corresponding to the communication hole  222 .  
      The communication passage is structured in such a manner that while the second protrusion  320  of the additive container  300  is in surface contact with the inner cap  220  of the adaptor  220 , the communication hole  222  and the drain hole  322  are coincident with or arranged crosswise with each other when the additive container  300  is turned. Thus, the accommodation space communicates with or is isolated from the interior of the bottle body, as shown in  FIG. 3 , so as to allow the content of the bottle body to mix with the additive of the container or to prevent the mixing.  
      The cover  400  is generally comprised of a hemispherical covering part  410 , with a fitting groove  420  formed around the circumference of the bottom of the covering part  410 , and has a discharging port  430  protruding in a pipe form at the center top of the covering part  410 .  
      A top cap  500  is provided to openably close the discharging port  430 . Preferably, the top cap  500  is fitted onto the discharging port  430  by pressing so as to readily open or close the discharging port  430 . More preferably, the top cap  500 , as will be explained later, is integrated via a connection cord  520  to the cover  400 , so that it can be utilized without loss. The connection cord  520  may be used as a carrying strap for the bottle. Alternatively, the top cap  500  may be tightened to the discharging port  430  through a screw-type engagement. In this case, the top cap has a structure that turns with respect to the connection cord.  
      In the figures, reference numeral  224  represents a seal flap which functions in conjunction with a seal ring  314  to prevent the leakage of the contents.  
      In this structure, the bottle according to the first embodiment of the present invention is assembled as follows. When the first protrusion  310  is pressed against the connection portion  230 , the locking ring  312  is locked with the locking groove  232  so that the additive container can rotate with restricted motion in the axial direction. In this state, the accommodation space  302  is filled with an additive, followed by the application of the cover  400  to the additive container and then the combination of the top cap  500  with the discharging port  430 . While being stored in the accommodation space  302 , the additive is sold to consumers. After removing a cap from the beverage bottle body  100 , consumers can screw the outer cap  210  to the mouth  110  to assemble a bottle as shown in  FIG. 2 . At this time, because the communication hole  222  does not communicate with the drain hole  322 , the contents of the bottle body  100 , such as coffee or soda water, are not introduced into the accommodation space  302  even when the bottle body is turned upside down.  
      The rotation of the additive container  300  around the adaptor may make the communication hole  222  coincident with the drain hole  322 , thereby communicating the interior of the bottle body with the accommodation space  302 . A user can drink the contents of the bottle body by taking off the top cap  500  and turning the bottle upside down. During passage through the accommodation space, the contents of the bottle body dissolve the additive contained in the accommodation space and then acquire appropriate tastes.  
      Although a description is given of a bottle which is sold containing an additive in the accommodation space  302 , the present invention is not limited thereto. The bottle according to the first embodiment of the present invention may be marketed with the accommodation space  302  void. That is, consumers may fill the accommodation space with additives appropriate for their tastes after removing the cover  400  from the additive container  300 , whether the additive container is combined with or separated from the bottle body  100 .  
       FIG. 4  is an exploded cross sectional view showing the structure of a bottle according to one version (1-1 embodiment) of the first embodiment of the present invention. This version has the same purpose as the first embodiment of the present invention.  
      Within the additive container  300 , a guiding conduit  340  extending in the axial direction is integrally provided. The guiding conduit preferably has a hemispheric end, with a plurality of spraying holes  342  uniformly formed therethrough.  
      In accordance with the 1-1 embodiment, while moving along the guiding conduit, the contents of the bottle body are effused through the spraying holes  342  in such a large contact area with the additive mass as to effectively dissolve the additive.  
      With reference to  FIG. 5 , there is an exploded cross sectional view showing the structure of a bottle according to another version (1-2 embodiment) of the first embodiment of the present invention. This version provides a model which avoids the difficulty in injection molding the guiding conduit.  
      In this embodiment, the guiding conduit is independently formed, and fitted into the first protrusion  310  through a screw-type engagement. That is, internal threads  316  are formed on the inner surface of the first protrusion  310 , while the guiding conduit  340  is provided with external threads  344  corresponding to the internal threads  316  on the outer surface at its open terminal portion and has a plurality of spraying holes  342  formed therethrough.  
      As such, the guiding conduit  340  is separately molded and combined with the first protrusion  310 . The 1-2 embodiment, although suffering from an increase in the number of used parts, enjoys the advantage of easy moldability and high workability.  
      Alternatively, the guiding conduit  340  may be combined with the first production  310  in a tight fitting manner instead of a screw-type engagement.  
      Referring to  FIG. 6 , there is a cross sectional view showing the structure of a bottle in accordance with the second embodiment of the present invention. This structure makes it easy to mix the contents with the additive and allows a consumer to drink the contents and the additive separately or mixed using a straw.  
      As in the previous embodiment, the bottle according to the embodiment is generally comprised of a bottle body  100 , an adaptor  200 , an additive container  300 , and a cover  400 .  
      The adaptor  200  comprises an engagement portion  240  which can be removably combined with the mouth of the bottle body, and a cylindrical support  250  which extends from the engagement portion  240  at a predetermined angle in external radial and axial directions with a locking ring  252  formed around the external circumferential surface thereof. A lower blocking panel  260  which blocks the flow of the contents in the axial direction is integrated into the support  250 . At the center of the lower blocking panel  260 , a lower shutter ring  270  having a communication hole  272  is integrally provided.  
      The additive container  300  having a locking groove  352  formed around the inner circumferential surface thereof is removably combined with the adaptor  200  by locking the locking groove  352  to the locking ring  252 . The additive container  300  is restricted from moving in the axial direction but can be rotated around the adaptor  200 . In the additive container  300 , an accommodation space  302  which is open at one end is provided to contain one or more additives therein. Defining the accommodation space  302  in the widthwise direction, an upper blocking panel  360  is integrally formed. At the center of the upper blocking panel  360 , an upper shutter ring  370  having a drain hole  372  is integrally formed.  
      As seen in the figure, the lower blocking panel  260  of the adaptor  200  runs upwards at an angle to the center while the upper blocking panel  360  of the additive container  300  runs downwards at an angle to the center.  
      Protruding from a central portion of the lower blocking panel  260 , the lower shutter ring  270  may be in a cylindrical form. The communication hole  272  is preferably formed at the bottom as well as lateral sides of the cylindrical lower shutter ring  270 . Likewise, the upper shutter ring  270  extends upwards from a central portion of the upper blocking panel  360  and is provided with a drain hole which is formed at opposite ends and lateral sides of the upper shutter ring  270 , corresponding to the communication hole  272 .  
      To be inserted into the upper shutter ring  360 , an extension part  274  is provided on the top of the lower shutter ring  260 , so as to prevent the contents from flowing out.  
      In the figure, reference numeral  224  represents a seal flap which functions in conjunction with a seal ring  314  to prevent the leakage of the contents.  
      Since the communication hole  272 , the drain hole  372 , the mouth  110  and the discharging port  430  are coaxially formed in the bottle of the second embodiment, a straw S can be inserted as seen in  FIG. 6 . In particular, whether the contents or the additive are consumed depends on the depth of insertion of the straw. For example, when the straw is inserted deeply, only the contents of the bottle body  100 , e.g., the soda pop or coffee, are consumed. On the other hand, shallow insertion allows the ingestion of the additive stored in the additive container as well as the contents. Because it has a structure such that both the communication hole  272  and the drain hole  372  are always open, this bottle itself is for sale only. When it is sold with an additive in the additive container, the bottle needs an additive element for closing the engagement portion  240 , such as a stopper or sticker.  
      In accordance with the present invention, the lower blocking panel  260  and the upper blocking panel  360  may run upwards and downwards, respectively, to the center at such angles as to be in surface contact with each other.  
       FIG. 7  is an exploded cross sectional view showing the structure of a bottle according to one version (2-1 embodiment) of the second embodiment of the present invention. In this embodiment, a communication hole and a drain hole, which are provided to the lower shutter ring and upper shutter ring, respectively, are coincident with or arranged crosswise with each other by turning the additive container around the adaptor. Thus, as the bottle body is opened or closed by changing the relative position of the communication hole and the drain hole, the contents remain isolated or become mixed with the additive.  
      In accordance with this embodiment, the lower blocking panel  260  protrudes upwards from its central portion to form a hemispheric lower shutter ring  270 . The lower shutter ring  270  has two or more communication holes which are formed at equal intervals around the axis. Protruding upwards from a central portion of the upper blocking panel  360 , an upper shutter ring  370  is configured to be a hemisphere such that it can be in surface contact with the lower shutter ring  270 . Corresponding to the communication holes  272 , two or more drain holes  372  are formed at equal intervals in the upper shutter ring  370  around the axis.  
      As the additive container rotates around the adaptor, the communication holes  272  and the drain holes  372  communicate with or across from each other. Since the holes are positioned in the center of the additive container, the contents of the bottle body are readily mixed with the additive of the additive container.  
      With reference to  FIG. 8 , there is an exploded cross sectional view showing the structure of a bottle according to a third embodiment of the present invention. In the bottle of this embodiment, an additive container is integrated into an adaptor. Thus, the bottle is generally comprised of a bottle body  100 , an additive container  600 , and a cover  400 .  
      Outlined by a support  620 , the additive container  600  is generally in a cylindrical form and has a funnel configuration at the bottom. At the end of the funnel, an engagement  610  is provided which is internally threaded and removably combined with the mouth  110  of the bottle body  100 . Acting as a bottom septum for an accommodation space, a blocking panel  630  is integrally formed within the support  620 . The blocking panel  630  protrudes at a central portion to form a hemispherical protrusion, around the circumference of which a plurality of communication holes  642  is preferably provided. Similar to the 2-1 embodiment, this bottle itself is for sale only. When it is sold with an additive in the additive container, the bottle needs an additive element for closing the engagement  610 , such as a stopper or sticker. Reference numeral  614  designates a fixing ring which is fitted onto the mouth  110  to immobilize the additive container.  
       FIG. 9  illustrates the structure of a bottle according to one version (3-1 embodiment) of the third embodiment in an exploded cross sectional view. In the bottle of this embodiment, not only are an additive container compartment and an adaptor compartment integrally formed, but also an inner cap is provided as an inner septum for the adaptor compartment.  
      In accordance with the 3-1 embodiment, the bottle has an inner cap  650  which is formed inside the engagement  610  and is inserted into the mouth  110  by pressing, with a plurality of communication holes  652  formed at the end thereof.  
      Press fitted into the mouth  110 , the inner cap  650  guarantees excellent sealing performance. The bottle can be marketed with a sticker attached using an adhesive to the end of the inner cap  650 . For use, the sticker may be detached.  
      With reference to  FIG. 10 , there is an exploded cross sectional view showing the structure of a bottle according to a fourth embodiment of the present invention.  FIGS. 11 and 12  further illustrate this bottle in an exploded perspective view and a cross sectional view showing an assembled state, respectively. The same elements as in previous embodiments are designated by the same or like numerals, with the omission of detailed descriptions therefor. This embodiment is concerned with a structure which more rapidly discharges the contents and more effectively closes or opens the communication passage upon rotation of the additive container.  
      Outlined by a support  250 , the adaptor  200  is generally cylindrical and has a funnel configuration at the bottom, with a locking ring formed around the external circumferential surface thereof. At the end of the funnel configuration, an engagement  240  is provided which is internally threaded and removably combined with the mouth  110  of the bottle body  100 . Acting as a top septum for the cylindrical adaptor, a lower blocking panel  260  is integrally formed at the top end of the support  250 . Two or more communication holes  262  are formed at equal intervals in the lower blocking panel  260 .  
      The additive container  300  comprises a cylindrical housing  350  defining an accommodation space  302  and has a locking groove  352  which is formed around the inner circumferential surface of the cylindrical housing  350  to lock with the locking ring  252 . Within the housing  350 , an upper blocking panel  360  is integrally formed, compartmentalizing the accommodation space in two in the transverse direction. Also, two or more drain holes  362  corresponding to the communication holes  262  are provided at equal intervals in the upper blocking panel  360 .  
      As shown in  FIG. 11 , the communication holes  262  and the drain holes  362  may each have a fan shape so that they coincide with or across from each other in response to the rotation of the additive container  300  around the adaptor  200 .  
      At least one of the communication holes  262  includes a stop flange  262   a  which protrudes upwards to be inserted into the drain holes  362 . Likewise, at least one of the drain holes  362  is provided with a stop flange  362   a  which protrudes downwards to be inserted into the communication holes  262 . If any of the holes has a stop flange, the same effect can be obtained whether the stop flange is provided to the communication holes or the drain holes.  
      In the fourth embodiment, the communication holes and the drain holes are large enough to allow the additive and the content to readily mix with each other.  
      With reference to  FIG. 13 , there is a cross sectional view showing the structure of a bottle according to a fifth embodiment of the present invention. As seen, the bottle includes an additive container which has an eggshell shape. In accordance with this embodiment, the bottle comprises a bottle body  100  having a mouth  110  with an external thread  112  formed around the external circumferential surface thereof, and an additive container  300  having an accommodation space  302  to contain an additive therein. The additive container  300  is provided at a predetermined position with an engagement  200  which is fitted onto the mouth  110  of the bottle body  100 . Further, the additive container  300  includes an outwardly protruding discharging port  304  at a position opposite the engagement  200 .  
      The engagement  200  consists of an outer cap  210  having an internal thread  212  engaged with the external thread  112  formed on the external circumferential surface of the mouth, and an inner cap  220  extending in the axial direction inside the outer cap  210 , defining an inlet  222  which communicates with the interior of the bottle body  100  and is tightly fitted into the mouth  110 .  
      Having an eggshell shape, the additive container  300  is preferably made from a flexible material which is readily deformed by external force.  
      The discharging port  304 , even though provided at an off-center position in the figure, may be formed at any position. When designing the bottle, the length and diameter of the discharging port must be taken into consideration. That is, the length and diameter may be determined on the basis of the output rate according to the inclination angle of the bottle.  
      The additive container containing ice cream in the accommodation space  302  may be displayed in a showcase, with aluminum foil closing the inlet  222  and the discharging port  304 . After removing the aluminum foil from the inlet  222  first, a consumer may tighten the additive container to the mouth  110  using the screw type engagement and then open the discharging port  304  to enjoy the taste provided.  
      When the bottle body is turned upside down, the contents such as soda pop are effused from the discharging port, dissolving the ice cream contained in the container.  
       FIG. 14  illustrates one version (5-1 st ) of the fifth embodiment of the present invention (the same elements as in the fifth embodiment are designated by the same reference numerals, without descriptions therefor. The bottle of this embodiment is characterized by a backflow preventer which functions to prevent the additive of the additive container  300  from flowing downwards into the bottle body  100 .  
      In the inlet, an anti-backflow valve is provided to allow the contents of the bottle body to flow into the additive container but prevent the reverse progress.  
      The anti-backflow valve includes a valve body  230  which extends from the inlet  222  toward the accommodation space  301  in the axial direction. The valve body  230  has a closed end and a holed side wall in which a valve hole  232  is formed. Within the valve body  230 , a valvule  240  is positioned to move in the axial direction so as to open or close the valve hole  232 . Formed around the inner circumferential surface of the inlet  222 , a protrusion ring  234  prevents the valvule  240  from being separated from the valve body  230 .  
      The valvule  240  is depicted to have a lozenge-shaped cross section, but is not limited thereto. For example, the valvule  240  may be a sphere.  
      When the bottle body  100  stands upright or the mouth  110  is directed upwards, the valvule  240  descends due to the inherent weight of the protrusion ring to close the valve hole  232 , thereby preventing the additive from flowing downwards into the bottle body  100 . On the other hand, when the bottle body  100  is turned upside down, the valvule  240  goes down to the closed end to open the valve hole  232 , so that the contents of the bottle body can flow into the accommodation space and effuse out of the discharging port.  
      Therefore, the installation of the anti-backflow valve in the inlet  222  makes it possible to prevent the additive from flowing into the bottle body from the accommodation space  302 . In the case that the additive container is filled with ice cream, its easy fusion at ambient temperatures provides greater opportunity to mix with the contents of the bottle body. The mixture of the melted additive and the contents, although effected, does not guarantee the tastes intended by the providers.  
       FIG. 15  is a view showing another version (5-2 embodiment) of the fifth embodiment of the present invention (in which the same elements as in Example 5 are designated by the same reference numerals, without an additional description therefor). This embodiment highlights the appearance of the additive container.  
      In this embodiment, the additive container  300  has an ice cream appearance. This increases product recognition as well as enhances brand images. Particularly, children may be attracted to such characteristic appearances.  
      Although shown as an ice cream shape, the additive container may be molded into various shapes. For example, if the additive emits an apple fragrance or provides an apple taste, the additive container may be in the shape of an apple. Of course, animal characters may be applied to the additive container.  
      With reference to FIGS.  16  to  18 , the structure of a bottle according to a sixth embodiment of the present invention is illustrated (in which the same elements as in the previous embodiments are designated by the same reference numerals, without an additional description therefor). In this embodiment, different configurations are given to the additive container and the cover and the accommodation space are divided into two.  
      The bottle according to this embodiment comprises a bottle body  100 , an engagement  200  fitted onto the mouth of the bottle body, an additive container  300 , integrated into the engagement  200 , having an accommodation space which is compartmentalized into a first space  302   a  and a second space  302   b  by an inner container  310 , and a cover  400  for covering the second space  302 , with a discharging port  402  formed thereon.  
      The inner container  310  is comprised of a connecting portion  312  extending inward in the radial direction from an open end, a vertical wall portion  314  extending in the axial direction from the connecting portion  312 , and a closing portion  316  defining a bottom. In the connecting portion, a plurality of communication holes  302   a  is formed to communicate the first space  302   a  with the second space  304   a.    
      A top cap  500  is provided on the discharging port  402 , functioning to open or close the second space  302   b.    
      When being removed from the discharging port  402 , the top cap  500  does not become separated from the bottle because it is connected to a connecting cord  520 , one end of which is fixed to a predetermined portion of the cover.  
      Also, the cap  500  has a pressure hole  510 . The same effect can be obtained by the formation of a pressure hole in the cover  400 .  
      A plurality of hooking protrusions  320  is formed around the circumferential surface of the open end of the additive container  300 . Correspondingly, a plurality of elastic hooks  412  hooked on the hooking protrusions  320  are formed in the lower end of the hemispherical covering part  410 .  
      When the bottle body having this structure according to the sixth embodiment is turned upside down, the contents, after being introduced into the first space  302   a , flow along the vertical side wall  314  and then into the second space  302   b  through the communication hole  312   a . Thereafter, the contents dissolve the additive contained in the second space  302   b  and flow out of the discharging port  402 .  
      When the bottle is turned from an upside down state to an upright state, the contents introduced into the second space  302   b  for the most part collect in the lower portion of the second space  302   b  while only a small portion returns back to the bottle body  100 . Thus, the contents remaining in the second space  302   b  dissolve the lower portion of the additive confined within the second space  302   b . When the bottle is tilted again, the contents sufficiently mixed with the additive are first effused, so that the user can enjoy the taste. Particularly, the bottle of this embodiment provides a solution to the problem caused by the entrance of the additive into the bottle body  100 .  
       FIG. 17  shows the structure of a bottle according to one version (6-1) of the sixth embodiment of the present invention (in which the same elements as in the previous embodiments are designated by the same reference numerals, without an additional description therefor). This embodiment is characterized by a different anti-backflow means.  
      In this bottle, an interceptive wall  230  protrudes toward the first space  302   a  from the inlet  222 , with a gap in the bottom of the inner container  310 .  
      In accordance with this embodiment, the mixture of the contents and the additive, even if remaining in the first space  302   a , scarcely flows back into the bottle body due to the interceptive wall, so that the contents can be kept pure in the bottle body. This structure is particularly useful when an additive is present in a large amount. Because the second space  302   b  is full of additive at first, the additive is ready to flow down through the communication hole  312   a . As the amount of additive introduced into the first space increases, there is an increasing possibility that the contents become turbid.  
      In  FIG. 18 , the structure of a bottle according to another version (6-2 embodiment) of the sixth embodiment of the present invention is depicted (in which the same elements as in the 6-1 embodiment are designated by the same reference numerals, without additional description therefor). The structure of this bottle is suitable for the case where the second space contains ice.  
      The inner container defining the second space  302   b  has a plurality of communication holes  312   a  in the connecting portion  312  and a plurality of communication holes  316   a  in the bottom  316 . The position of the communication holes  316   a  in the bottom  316  of the inner container is out of the area corresponding to the inlet, that is, beyond the interceptive wall  230 . In this structure, the contents which have been in the second space  302  are prevented from re-entering the bottle body when they fall from the second space into the first space through the communication holes  316   a.    
      When the bottle is stood upright after the contents of the bottle body flow into the second space through the communication holes  312  of the connection portion  312 , the remaining contents which are not discharged out of the discharging port  402  gather in the second space  302  and are introduced through the communication holes  316   a  of the bottom  316  into the first space  302   a . These returning contents cannot flow into to the bottle body due to the interceptive wall, but remain in the first space  302   a . Subsequently, when the bottle body is again turned upside down, the contents remaining in the first space  302   a  are first introduced into the second space  302   b.    
      As mentioned above, the 6-2 nd  embodiment of the present invention is suitable for the case in which the additive is ice. That is, when the contents inflowing from the bottle body  100  are brought into contact with the ice contained in the second space  302 , the consumer enjoys cool tastes. Additionally, because the contents which are not discharged but remain in the second space  302   b  go back to the first space  302   a  through the communication holes  316   a , the ice is prevented from being melted by the remaining contents in the second space  302 .  
       FIG. 19  shows the structure of a bottle according to a further version (6-3) of the sixth embodiment of the present invention (in which the same elements as in the 6-1 embodiment are designated by the same reference numerals, without additional description therefor). The bottle of this embodiment is featured by an enlarged volume of the first space in the additive container  300 .  
      The additive container  300  has a bottom  300  which is inclined downwards at a predetermined angle from the outer cap  210 .  
      Accordingly, as shown in  FIG. 19 , the bottom, together with the interceptive wall  230 , increases the volume of the first space. This structure can store a significant amount of contents without the help of the interceptive wall  230 . Particularly, the external circumference of the additive container  300  is disposed near that of the bottle body  100 , so that the bottle looks neat in its entirety and has a uniform appearance.  
      With reference to  FIG. 20 , a bottle structure is depicted according to a still further version (6-4 th ) of the sixth embodiment of the present invention (in which the same elements as in the sixth embodiment are designated by the same reference numerals, without additional description therefor). The feature of this embodiment resides in that the inner surface of the cover is provided with baffles impeding the flow of the contents so as to increase the mixing efficiency between the contents and the additive.  
      In accordance with this embodiment, a plurality of concentric ring-type protrusions  420  is provided around the axis on the inner surface of the cover  400 . The ring-type protrusions  420  are arranged at equal intervals and each is inclined at an acute angle against the flow of the contents.  
      The ring-type protrusions  420  function to prolong the time during which the contents are influent through the communication holes  312   a  and cause turbulent content flow, so that the influent contents flow with prolonged contact with the additive, thereby improving the mixing efficiency therebetween.  
      In the 6-4 th  embodiment of the present invention, the problem expected where the contents flowing through the communication holes  312   a  into the second space  302   b  flow without resistance and are discharged out of the discharging port  402 , that is, the problem in which the contents are discharged unmixed, can be solved.  
       FIG. 21  shows the structure of a bottle according to still another version (6-5 th ) of the sixth embodiment of the present invention (in which the same elements as in the fifth and sixth embodiments are designated by the same reference numerals, without additional description therefor). The bottle is based on the structure described in the sixth embodiment while adopting the anti-backflow means of the fifth embodiment.  
      In the inlet  222 , an anti-backflow valve, including a valve body  230  and a valvule  240 , is provided. The valve body  230  has a valve hole  232 . Formed around the inner circumferential surface of the inlet  222 , a protrusion ring  234  prevents the valvule  240  from departing from the valve body  230 . As seen in the figure, the valve body  230  is in close contact with the bottom of the second space  302   b  or is integrated into the second space  302   b.    
      When the bottle in accordance with the 6-5 th  embodiment of the present invention is turned upside down, the valvule  240  moves down due to its inherent weight to open the valve hole  232 , so that the contents of the bottle body can flow into the accommodation space and effuse out of the discharging port. On the other hand, when the bottle is stood upright or the mouth  110  is directed upwards, the valvule  240  descends due to its inherent weight to close the valve hole  232 , thereby preventing the additive from flowing downwards into the bottle body  100 . At this time, the contents present in the second space are completely confined by the vertical side wall  314  of the inner container  310 , so that the contents of the bottle body  100  are kept more pure.  
       FIG. 22  is a view of a bottle according to yet another version (6-6) of the sixth embodiment of the present invention (in which the same elements as in the fifth and sixth embodiments are designated by the same reference numerals, without an additional description therefor). The feature of this embodiment resides in that the inner container  310  is separately formed to be more moldable, and is then combined with the additive container in a tight fitting manner.  
      Separately from the additive container  300 , an inner additive container  310  is molded. A plurality of vertical piece couples  350 , each couple having a fitting gap  352  therebetween, is provided on the external side walls of the inner container  310  while a plurality of fixing ribs  360  to be inserted into the fitting gap  352  is formed on the inner side walls of the additive container  300 . A locking protrusion  354  is provided on each vertical piece  350 . Correspondingly, a locking groove  362  to which the locking protrusion  354  is locked is formed on each side of the fixing rib  360 . Accordingly, when combined with the additive container, the inner container is restricted from moving in the axial direction.  
      In the 6-6 th  embodiment of the present invention, when the inner container is inserted into the additive container  300  with the fixing rib  360  targeting the fitting gap  352 , the fixing rib  360  interferes with the locking protrusion  354  to further open the couple of the vertical pieces. Subsequently, when the fixing rib  360  is further inserted into the fitting gap until the locking protrusion  354  reaches the locking groove  362 , the vertical pieces  350  are elastically restored to combine with the fixing rib  360 . Preferably, the inner container is structured to put the bottom of the connection portion  312  on the top of the fixing rib  360  in synchronicity with the combination of the locking protrusion  354  with the locking groove  362 . Additionally, the bottom  316  of the inner container  310  must be spaced apart at a predetermined distance from the interceptive wall  230  when the connection portion  312  is put on the fixing rib  360 .  
      Structured to tightly fit the inner container  310  to the additive container  300 , the bottle according to the 6-6 th  embodiment can be readily assembled and is easy to clean.  
      With reference to FIGS.  23  to  25 , the structure of a bottle according to a 6-7 th  embodiment of the present invention (in which the same elements as in the 6-6 th  embodiment are designated by the same reference numerals without additional description therefor) is shown. This embodiment features an engagement structure between the cover  400  and the additive container  300 .  
      In this embodiment, a seating groove  370  is formed around the external circumferential surface of the open end of the additive container  300 , with a ring-type locking protrusion  372  formed at the end thereof. A fixing ring  430  tightly fitted to the seating groove  370  is integrated through a support piece  432  to the lower end of the cover  400 . A stopper  434  which protrudes outwards in the radial direction is formed on one side of the fixing ring  430 . A locking piece  416  having a locking hole  416   a  into which the stopper  434  is inserted is integrally provided to the lower end of the cover  400 . Also the cover has a locking protrusion  414  to which the locking protrusion is locked.  
      A sleeve  440  integrally and axially extends in the cover  400  at a predetermined position spaced inward apart from the end of the cover  400 . An extension part  442  is integrally formed at a part of the sleeve  440  which is provided with the support piece  432 . The extension part  442  extends downward such that it has an inclined part.  
      In each of the 6-7 th  embodiment of the present invention, an inner container  310  is assembled in the additive container  300  as shown in  FIG. 24 . A fixing ring  430  is fitted around a seating groove  370  at a position above the top of the inner container  310 . The cover  400  is rotatable around the support piece  432  so that the cover  400  can be opened as shown in  FIG. 13   c  or closed and firmly locked as shown in  FIG. 13   b  in which the stopper  434  engages with the locking hole  416   a  of the locking piece  416 . The locking piece  416  is made of a plastic material so that the piece  416  can be elastically deformed, thus elastically engaging with or disengaging from the stopper  434 . The extension part  442  acts as a position guider to determine the assembling position of the cover  400  when the cover  400  is assembled with the storage container  300 .  
      Thus, the cover  400  is not undesirably detached from the additive container  300 , so that the cover  400  can be easily handled and managed by a user, and can be firmly locked to the additive container  300  when necessary.  
       FIG. 26  shows the structure of a bottle according to a seventh embodiment of the present invention (in which the same elements as in the sixth embodiment are designated by the same reference numerals, without additional description therefor). The feature of this embodiment is a light emitting means provided on the external circumference of the cover.  
      On the external circumference of the cover, a ring-type protrusion  450  is provided, along which a plurality of light emitting diodes  452  are arranged. A battery  530  is installed within the top cap  500 , with a circuit board  532  positioned atop the battery  530 . The circuit board  532  is finished with a cap  534 .  
      From the battery  530 , electric power is supplied to the light emitting diodes  452  through an electric wire  538  embedded in the connection cord  520 .  
      Additionally, a switch  536  which is exposed from the lower end of the top cap  500  is provided on the circuit board  532 . Whenever the top cap  500  is closed, the switch is pressed by the discharging port  402  to connect or disconnect the battery power.  
      When the top cap  500  is opened, the switch is in an ON-state so as to supply electric power to the light emitting diodes  452 . According to the design of the circuit board  532 , the light may be emitted when the top cap  500  is opened or closed. In addition, music IC may be further provided to the bottle, so that music may be generated along with the light.  
      The application of the light emitting means to the surface of the bottle in accordance with the seventh embodiment of the present invention may create interest and curiosity in the product, particularly at night.  
      With reference to  FIG. 27 , a bottle is illustrated in accordance with a 7-1 st  embodiment of the present invention, featuring a light emitting means provided on the additive container. As seen in the figure, a plurality of light emitting diodes  382  is embedded in a ring-type protrusion  380  formed around the external circumferential surface of the additive container  300 . The connecting cord  520  is connected to the ring-type protrusion  380 . The rest of the structure is the same as in  FIG. 26 .  
       FIG. 28  shows a structure according to an eighth embodiment of the present invention (in which the same elements as in the sixth embodiment are designated by the same reference numerals, without an additional description therefor). This embodiment features a mixing means adapted to be useful for wide-mouth containers such as cups.  
      A cup body  100  is provided which has an open end  710  with an external thread  712  formed around an external circumferential surface thereof. Likewise, a corresponding internal thread  390  is formed around an internal surface of a lower end of an additive container  300 . The cup body  100  is tightened to the additive container  300  through a screw type engagement. Within the additive container  300 , an inner container is integrally formed which defines the accommodation space  302  together with the cover and has therein communication holes  312   a  for communicating the accommodation space  302  with the interior of the cup body  700 . A cover  400  having a discharging port  402  therein is mounted onto the additive container  300 , opening or closing the accommodation space  302 . A top cap  500  is provided atop the discharging port  402  and is settled on the cover  400  or the additive container  300  through a connection cord  520  which is directly connected to the top cap  500  at one end and to the cover  400  or the additive container  300  at the other end. The engagement between the additive container  300  and the cup body  700  may be accomplished in a tight fitting manner instead of a screw-type manner.  
      In this embodiment, an additional adaptor (not shown) may be provided for coping with changes in the size of the cup body mouth. When the cup body has a mouth size different from that of the additive container, an adaptor is used to connect them, thereby enhancing the compatibility of the bottle. Additionally, a sealable hole to which a straw can be applied may be provided in the bottom  316  of the inner container  310  as shown in  FIG. 6 . Also, the bottom  316  of the inner container  310  may be stepped. Straws are individually applied to the steps formed. A deep step may be used as a space for containing ice cream therein while a shallow step may be a passage through which the contents of the cup body  700  are directly consumed by use of a straw. In this regard, the content of the cup body  700  can be consumed using a straw penetrating through the shallow step while another straw is applied to the deep step to consume the ice cream or a mixture of the ice cream and the contents. For this, of course, two straws are used (in this case, the top cap must have two holes for respectively adopting the two straws): one penetrates through the shallow bottom to remove the contents of the cup body  700  therethrough: the other is applied to the shallow bottom to directly remove ice cream or an ice cream mixture (coke float) therethrough. The transportation of the contents from the cup body into the accommodation space may utilize the communication holes when the cup body is pressed or a passage formed when a straw penetrates through the bottom of the additive container. The transportation passages may be selected by the manufacturer or the user.  
      The eighth embodiment of the present invention is suitable for wide-mouth bottles and, particularly when contents and an additive are consumed simultaneously at home. For example, because contents are difficult to put into a narrow-mouth bottle at home, the eighth embodiment of the present invention is very useful.  
      Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.  
     INDUSTRIAL APPLICABILITY  
      As described above, the present invention provides a bottle comprising a bottle body for containing contents therein, an additive container for containing an additive therein, a cover, capped with a top cap, for covering the additive container and defining an accommodation space together with the additive container, and an engagement for combining the bottle body with the additive container and optionally communicating the interior of the bottle body with the accommodation space, which can be distributed on the market while the accommodation space retains an additive. Therefore, the bottle of the present invention has a structure which allows at least two different materials to be carried and efficiently mixed immediately before ingestion.  
      Additionally, the bottle body may be separated from the additive container so that different materials can be separately stored and then combined with each other upon use. Accordingly, the bottle of the present invention can open a new market with greatly enhanced storage performance and economical advantages.
