Description:
BACKGROUND 
     Technology Field 
     The present disclosure relates to a portable container and a lid structure thereof. In particular, this disclosure relates to a portable container for preparing beverage and a lid structure thereof including an edible part. 
     Description of Related Art 
     Most of the conventional eco-friendly containers (portable containers) on the market only have the function of containing water or beverage for drinking. When using the eco-friendly containers to drink tea or coffee, most people use portable tea bags or coffee bags to brew so as to prepare the beverage. In this way, the consumers must purchase the portable containers and the tea bags or coffee bags at the same time. When preparing the beverage, the consumer needs to tear off the package of the tea bag or coffee bag, put the tea bag or pour the coffee powder from the package into the eco-friendly container, and then pour ice water or boiled water into the eco-friendly container for the purpose of brewing tea or coffee. This pstore the tea bags or coffee bags. In addition, this method can only allow the drinker to drink the beverage contained or brewed in the container, and the drinker cannot simultaneously enjoy beverages of different flavors in the same eco-friendly container. If the drinker wants to enjoy a snack, he/she needs to bring the snack additionally to accompany with the prepared beverage. 
     In addition, freshly brewed or filled beverages are often too cold or too hot for the drinker. However, the drinker may not recognize the exact temperature of the beverage by touching the container when the beverage is placed in the container, so the drinker may be easily scalded inadvertently. Moreover, even if the drinker has noticed that the beverage is too cold or too hot, he/she still has to sip the beverage or wait a long time until the temperature of the beverage rises or drops to a temperature suitable for drinking. If the waiting time is too long, the temperature of the beverage will change too much, so the drinker may not enjoy the beverage of the desired temperature. This is very inconvenient. 
     Furthermore, when using the eco-friendly container, if the user carries it carelessly or the container receives a collision, the liquid in the container may be spilled, which will not only cause waste, but also cause inconvenience to the drinker. 
     Therefore, it is an important subject to provide a portable container and a lid structure thereof that can adjust the temperature and flavor of the beverage in the container based on the design of the lid structure, so that the drinker can enjoy the beverage of different flavors with a proper temperature, thereby enhancing the convenience in drinking. In addition, the lid structure can provide a snack so as to increase the fun of drinking.

The flavor portions  313 ,  313   a ,  313   b , and  313   c  can be provided on at least a part of the inner surfaces of the bottom portion  311  and/or the annular wall  312  facing the accommodating space S by baking, spraying, coating, printing, screen printing, placing, embedding, or sticking. For example, the edible and soluble flavor portions  313 ,  313   a ,  313   b  and  313   c  can be used to increase the flavor of the liquid L (liquid L is shown by the horizontal dashed line in the figure) when the drinker drinks. In addition, although  FIG. 1H  shows that the flavor portion  313   c  of the first part  31   c  is only provided on a part of the inner surface of the bottom portion  311  and the annular wall  312  facing the accommodating space S and has a stripe shape, the flavor portion  313   c  can also be provided in a special pattern such as, for example but not limited to, a text, latte art, flower, animal or cartoon character, which can be used in conjunction with a transparent second part  32  for increasing the visual interest while adjusting the flavor and temperature of the beverage. 
     The operations of utilizing the flavor portion to increase the flavor of the contained liquid in the portable container will be described hereinafter with reference to  FIGS. 1C to 1E .  FIG. 1D  to  FIG. 1E  are schematic diagram showing the continuous operations in drinking status of the portable container of  FIG. 1C . When the user wants to add the flavor of the flavor portion  313  to the liquid L in the container, the portable container  1  should first be tilted toward the first opening  3121  for a few seconds to allow the liquid L to flow into the accommodating space S (as shown in  FIG. 1D ). Then, the portable container can be returned to the stand-up position. At this time, the excess liquid L will flow from the second openings  3122  (referring to  FIG. 1B , while the sectional views of  FIGS. 1C to 1E  do not show the second openings  3122 ) back to the inside of the containing portion  2 . Since the flavor portion  313  is edible and soluble, after the liquid L flows into the accommodating space S, it will contact the flavor portion  313 , so that the flavor portion  313  can be dissolved in the liquid L. Accordingly, the liquid L will be added with the flavor of the flavor portion  313 . After that, the portable container  1  is directly tilted toward the third opening  321  (as shown in  FIG. 1E ), and the user can drink the liquid L added with the flavor of the flavor portion  313 . For example, as shown in  FIG. 1C , the liquid L is hot coffee, and the flavor portion  313  is chocolate, which can be arranged on the inner surface of the bottom portion  311  and the annular wall  312  facing the accommodating space S by spraying, coating or sticking. The user can proceed the continuous operations with the portable container in drinking status so as to make the hot coffee enter the accommodating space S of the first part  31  from the first opening  3121 , and then shake the container or adjust the period of remaining the hot coffee in the accommodating space S based on personal taste. Accordingly, the chocolate is dissolved in the hot coffee, and then the hot coffee with a chocolate flavor (also called mocha coffee) can be provided from the third opening  321  of the second part  32 . Here, although the liquid L is hot coffee and the flavor portion  313  is chocolate as an example for illustration, the liquid L can be cold or hot drink such as, for example but not limited to, water, coffee, milk, black tea, green tea, milk tea or any of other drinks. The flavor portion  313  can be, for example but not limited to, cinnamon, cardamom, hazelnut, vanilla powder, vanilla block, chocolate powder, brandy, lemon peel, orange peel, coconut milk, coconut milk, coconut oil, cream, birch mushroom,  ganoderma, cordyceps , banana, blue-green seaweed, agave ginger syrup, turmeric powder, rosemary, honey, brown sugar, etc., or any of other materials with flavor function, or that material that can be added to beverage made of easily soluble biscuits, meringue, fondant, flavored ice cubes, liquid flavor packets, solid flavor packets, powder flavor packets or any of other easy-to-dissolve flavor combinations, and this disclosure is not limited thereto. The above-mentioned easily soluble biscuits, meringue, fondant, flavored ice cubes, liquid flavor packets, solid flavor packets, powder flavor packets, or a combination thereof can be provided on at least a part of the inner surfaces of the bottom portion  311  and/or the annular wall  312  facing the accommodating space S by baking, spraying, coating, printing, screen printing, placing, embedding, or sticking, and this disclosure is not limited thereto. That is, the type of liquid, the flavor and material of the flavor portion, the manner and range of arranging the flavor portion on at least a part of the inner surface of the bottom portion  311  and/or the annular wall  312  facing the accommodating space S can be made according to the needs of the user, and this disclosure is not limited thereto. 
     Referring to  FIGS. 1C to 1E , in this embodiment, the first part  31  is an artificial edible starch body, such as, for example but not limited to, baked hard biscuits or dentifrice. In details, the artificial edible starch body of the first part  31  is not easy soluble, and the flavor part  313  of the first part  31  is soluble (easy soluble). Therefore, when the liquid L enters the accommodating space S of the first part  31  through the first opening  3121  of the first part  31 , the flavor portion  313  can be dissolved in the liquid L (while retaining the edible starch body), and the user can drink the flavored liquid L containing the flavor portion  313  from the third opening  321  of the second part  32 . After the user finishes the beverage, he/she can take the first part  31  (the edible starch body) to eat directly. This not only can enjoy different flavored beverages, but also can enjoy flavored biscuits soaked in a drink so as to add fun. Particularly, the first part  31  not only comprises the flavor portion  313  to add flavor to the liquid L and can also be directly ate, but also has the function of maintaining and adjusting the temperature of the liquid L. When the liquid L enters the accommodating space S of the first part  31  from the opening  3121  of the first part  31 , a part of the liquid L can be allowed to stay in the accommodating space S to isolate it from the most part of liquid L in the containing portion  2 , thereby adjusting the temperature of the liquid L in the accommodation space S and maintaining the temperature of the liquid L in the accommodation space S by isolating the most part of liquid L in the containing portion  2  from the outside. In addition, the flavor of the flavor portion  313  can be added to the liquid L in the accommodating space S, and the user can drink from the third opening  321  of the second part  32  to enjoy the temperature-appropriate liquid L with the flavor of the flavor portion  313  (neither too hot nor too cold). 
     Referring to  FIGS. 1C to 1E  again, in this embodiment, the flavor portion  313  can also be mixed with the edible starch of the first part  31  and then made into an artificial edible starch body. In other words, the flavor portion  313  can be mixed with the edible starch of the first part  31 , and the flavor portion  313  and the edible starch of the first part  31  can together form an integrally formed single component (an edible starch body). When the liquid L enters the accommodating space S of the first part  31  from the first opening  3121  of the first part  31 , the flavor portion  313  mixed in the first part  31  can be dissolved in the liquid L (while retaining the edible starch). Then, the user can drink the liquid L with the flavor of the flavor portion  313  from the third opening  321  of the second part  32 . In particular, the edible starch ingredients such as, for example but not limited to, wheat flour (or flour),  quinoa  flour, potato starch, corn starch, sweet potato starch, glutinous rice flour, rice flour, cassava flour, lotus root flour or other edible starches well-known to skilled persons in the art.

Accordingly, when the second part  32  covers an outer periphery of the rim, it will not be interfered by the first part  31   f ′, which is disposed higher than the rim, and may fail to cap the containing portion  2 . In addition, the higher annular wall  312   f ′ can increase the capacity of the accommodating space S for accommodating the liquid L, so that it is possible to adjust the flavor and temperature of a larger amount of liquid L, thereby increasing the convenience of drinking. 
     Please refer to  FIGS. 5A to 5B , wherein  FIG. 5A  is a schematic diagram showing a portable container according to a fifth embodiment of this disclosure, wherein the lid structure is applied to the containing portion, and  FIG. 5B  is a perspective schematic view of the assembled portable container of  FIG. 5A . The structure, components and functions of the portable container  1   g  of the fifth embodiment are mostly the same as those of the above-mentioned portable container  1  of the first embodiment, so the detailed descriptions thereof will be omitted. The first embodiment and the fifth embodiment are different in the configuration of the first part of the lid structure. In this embodiment, the first part  31   g  of the lid structure  3   g  further comprises a partition portion  316   g . The partition portion  316   g  is configured on the inner surface of the bottom portion  311   g  facing the accommodating space S, and two ends of the partition portion  316   g  connect to the annular wall  312   g  for separating the accommodating space S into a first accommodating space S 1  and a second accommodating space S 2 . In this embodiment, the first part  1   g  comprises at least two flavor portions  313   g  and  313   g ′, and the at least two flavor portions  313   g  and  313   g ′ are arranged in the first accommodating space S 1  and the second accommodating space S 2 , respectively. In this embodiment, the outer periphery of the annular wall  312   g  is configured with a first opening  3121 , and the first opening  3121  is arranged corresponding to the partition portion  316   g . As shown in the figure, the first opening  3121  is arranged corresponding to one end of the partition portion  316   g  and also corresponding to both of the first accommodating space S 1  and the second accommodating space S 2 . 
     The operations of utilizing the flavor portion to increase the flavor of the contained liquid in the portable container will be described hereinafter with reference to  FIGS. 5C to 5E .  FIG. 5C  to  FIG. 5D  are schematic diagram showing the continuous operations in drinking status of the portable container of  FIG. 5B , and  FIG. 5E  is a schematic diagram showing another drinking status of the portable container of  FIG. 5B . For example, when the user wants to add the flavor of the flavor portion  313   g  to the liquid L in the container, the portable container  1   g  should first be tilted toward the first opening  3121  and the first accommodating space S 1  (see the arrow direction D 3  of  FIG. 5C ) for a few seconds to allow the liquid L to flow into the first accommodating space S 1  (as shown in  FIG. 5C ). Then, the portable container can be returned to the stand-up position. At this time, the excess liquid L will flow from the second openings  3122  back to the inside of the container portion  2 . Since the flavor portion  313   g  is edible and soluble, after the liquid L flows into the first accommodating space S 1  (as shown in  FIG. 5D ), it will contact the flavor portion  313   g , so that the flavor portion  313   g  can be dissolved in the liquid L. Accordingly, the liquid L will be added with the flavor of the flavor portion  313   g . After that, the portable container  1   g  is directly tilted toward the third opening  321 , and the user can drink the liquid L added with the flavor of the flavor portion  313   g . Similarly, when the user wants to add the flavor of the flavor portion  313   g ′ to the liquid L in the container, the portable container  1   g  should first be tilted toward the first opening  3121  and the second accommodating space S 2  (not shown) for a few seconds to allow the liquid L to flow into the second accommodating space S 2 . Then, the portable container can be returned to the stand-up position. At this time, the excess liquid L will flow from the second openings  3122  back to the inside of the container portion  2 . Since the flavor portion  313   g ′ is edible and soluble, after the liquid L flows into the second accommodating space S 2 , it will contact the flavor portion  313   g ′, so that the flavor portion  313   g ′ can be dissolved in the liquid L. Accordingly, the liquid L will be added with the flavor of the flavor portion  313   g ′. After that, the portable container  1   g  is directly tilted toward the third opening  321 , and the user can drink the liquid L added with the flavor of the flavor portion  313   g ′. In addition, when the user wants to add both of the flavors of the flavor portions  313   g  and  313   g ′ to the liquid L in the container, the portable container  1   g  should first be tilted toward the first opening  3121  (not shown) for a few seconds to allow the liquid L to flow into the first accommodating space S 1  and the second accommodating space S 2 . Then, the portable container can be returned to the stand-up position (As shown in  FIG. 5E ). At this time, the excess liquid L will flow from the second openings  3122  back to the inside of the container portion  2 . Since the flavor portions  313   g  and  313   g ′ are edible and soluble, after the liquid L flows into the first accommodating space S 1  and the second accommodating space S 2 , it will contact the flavor portions  313   g  and  313   g ′, so that the flavor portions  313   g  and  313   g ′ can be dissolved in the liquid L. Accordingly, the liquid L will be added with both flavors of the flavor portions  313   g  and  313   g ′. After that, the portable container  1   g  is directly tilted toward the third opening  321 , and the user can drink the liquid L added with the flavors of the flavor portions  313   g  and  313   g ′. For example, as shown in  FIG. 5B , the liquid L is hot coffee, the flavor portion  313   g  is chocolate, and the flavor portion  313   g ′ is milk, wherein the chocolate and milk can be arranged on the inner surface of the bottom portion  311   g  and the annular wall  312   g  facing the first accommodating space S 1  and the second accommodating space S 2  by spraying, coating, printing, screen printing, placing, embedding, or sticking. The user can proceed the continuous operations with the portable container in drinking status so as to make the hot coffee enter the first accommodating space S 1  and/or the second accommodating space S 2  of the first part  31   g  from the first opening  3121  so as the dissolve the chocolate and/or milk into the hot coffee. Accordingly, the hot coffee with a chocolate and/or milk flavor (chocolate coffee, latte or chocolate latte, also known as mocha flavored coffee) can be provided from the third opening  321  of the second part  32 . 
     Please refer to  FIGS. 6A to 6B , wherein  FIG. 6A  is a schematic diagram showing a portable container according to a sixth embodiment of this disclosure, wherein the lid structure is applied to the containing portion, and  FIG. 6B  is a perspective schematic view of the assembled portable container of  FIG. 6A . The structure, components and functions of the portable container  1   h  of the sixth embodiment are mostly the same as those of the above-mentioned portable container  1   g  of the fifth embodiment, so the detailed descriptions thereof will be omitted. The sixth embodiment and the fifth embodiment are different in the configuration of the first opening of the first part of the lid structure. In this embodiment, the outer periphery of the annular wall  312   h  comprises two first openings  3121  and  3121 ′, which are arranged corresponding the first accommodating space S 1  and the second accommodating space S 2 , respectively. Each of the first openings  3121  and  3121 ′ is disposed close to one end of the partition portion  316   h.    
     Please refer to  FIGS. 6C to 6D , wherein  FIG. 6C  to  FIG. 6D  are schematic diagram showing different drinking statuses of the portable container of  FIG. 6B . For example, when the user wants to add the flavor of the flavor portion  313   h  to the liquid L in the container, the portable container  1   h  should first be tilted toward the first opening  3121  and the first accommodating space S 1  for a few seconds to allow the liquid L to flow into the first accommodating space S 1  (as shown in  FIG. 6C ). Then, the portable container can be returned to the stand-up position. At this time, the excess liquid L will flow from the second openings  3122  back to the inside of the container portion  2 . Since the flavor portion  313   h  is edible and soluble, after the liquid L flows into the first accommodating space S 1  (as shown in  FIG. 6C ), it will contact the flavor portion  313   h , so that the flavor portion  313   h  can be dissolved in the liquid L. Accordingly, the liquid L will be added with the flavor of the flavor portion  313   h . After that, the portable container  1   h  is directly tilted toward the third opening  321 , and the user can drink the liquid L added with the flavor of the flavor portion  313   h . Similarly, when the user wants to add the flavor of the flavor portion  313   h ′ to the liquid L in the container, the portable container  1   h  should first be tilted toward the first opening  3121 ′ and the second accommodating space S 2  (not shown) for a few seconds to allow the liquid L to flow into the second accommodating space S 2 . Then, the portable container can be returned to the stand-up position. At this time, the excess liquid L will flow from the second openings  3122  back to the inside of the container portion  2 . Since the flavor portion  313   h ′ is edible and soluble, after the liquid L flows into the second accommodating space S 2 , it will contact the flavor portion  313   h ′, so that the flavor portion  313   h ′ can be dissolved in the liquid L. Accordingly, the liquid L will be added with the flavor of the flavor portion  313   h ′. After that, the portable container  1   h  is directly tilted toward the third opening  321 , and the user can drink the liquid L added with the flavor of the flavor portion  313   h ′. In addition, when the user wants to add both of the flavors of the flavor portions  313   h  and  313   h ′ to the liquid L in the container, the portable container  1   h  should first be tilted toward the first openings  3121  and  3121 ′ (not shown) for a few seconds to allow the liquid L to flow into the first accommodating space S 1  and the second accommodating space S 2 . Then, the portable container can be returned to the stand-up position (As shown in  FIG. 6D ). At this time, the excess liquid L will flow from the second openings  3122  back to the inside of the container portion  2 . Since the flavor portions  313   h  and  313   h ′ are edible and soluble, after the liquid L flows into the first accommodating space S 1  and the second accommodating space S 2 , it will contact the flavor portions  313   h  and  313   h ′, so that the flavor portions  313   h  and  313   h ′ can be dissolved in the liquid L. Accordingly, the liquid L will be added with both flavors of the flavor portions  313   h  and  313   h ′. After that, the portable container  1   h  is directly tilted toward the third opening  321 , and the user can drink the liquid L added with the flavors of the flavor portions  313   h  and  313   h ′. Compared to the fifth embodiment, this embodiment has a design of two first openings  3121  and  3121 ′, so that it is easier to control the liquid to flow into the first accommodating space S 1  only or into the second accommodating space S 2  only.
