     TECHNICAL FIELD 
     The present disclosure pertains to the field of liquid containers. More particularly, the present disclosure pertains to the field of containers that help maintain the liquid&#39;s temperature and allow for easy consumption. Even more particularly, the present disclosure relates to liquid containers which maintain the liquid&#39;s temperature, facilitate liquid consumption, minimize the chances of spillage and leakage. 
     BACKGROUND 
     In the related art, conventional closed liquid containers, often called bottles, cups, mugs, coffee cups, thermoses, etc., only allow easy access to the main reservoir of liquid. In the case of a liquid desired at an elevated temperature, this causes some problems. When considering a standard cup or bottle, one must wait until the liquid cools to a safe temperature before consuming. This waiting is also accompanied by frequent testing of the liquid to determine its temperature either by tasting it from the container and risking a burn, or pouring the liquid out and letting it cool in the air to the desired temperature. When the liquid reaches the desired consumption temperature a window of opportunity is then opened when the liquid must be consumed before it drops below such temperature. If the mug is not insulated, this window of time may be quite short. In the case of an insulated mug or container, the window of time to consume the liquid is much larger; however, the insulating properties of the container can also make it difficult to judge when the liquid is at a safe temperature to consume and will prolong the time taken for the liquid to reach the desired temperature, both problems of which are well-known to those who drink hot beverages. An additional issue with related art liquid containers is the ability to clean them effectively, especially when the container has moving and sealing components, in most instances the complexity of the pumps and valves of related art liquid containers, prevent them from being easily removable and cleaned.

     Shown throughout the figures, the subject matter of the present disclosure is generally directed toward an upper portion, such as a small cup shaped lid, which either has a pump or is facilitated by a pump for the purpose of pumping liquid from the inside of a bottle or container to a reservoir on the lid. 
     Example 1 
     Embodiment with a Closable Spout 
     Referring to  FIG. 1A , this diagram illustrates a perspective view of a vessel  1 , such as a bottle or a container, in accordance with an embodiment of the present disclosure. The vessel  1  comprises a lower portion  1   a , having a holding reservoir  2 , and an upper portion  1   b , having a drinking reservoir  3 , a closable spout  5 , and a pump mechanism  4 . The holding reservoir  2  is used to store the bulk of the liquid. When a user (not shown) desires, the user will use the accompanied pump mechanism  4  to move the liquid into the drinking reservoir  3  which accommodates a volume of liquid that is less than the maximum volume capacity of the holding reservoir  2 . Once the liquid (not shown) is disposed in the drinking reservoir  3 , the user may consume the liquid when it meets the user&#39;s specific preferences. The pump mechanism  4  comprises a pump membrane  4   a  coupled with a receiving edge of the upper portion  1   b.    
     Still referring to  FIG. 1A , in further detail, the holding reservoir  2  comprises a size for accommodating a volume of liquid that is adequate for a user consuming his or her beverage of choice. The size of the holding reservoir  2  is not limited, but is capable of accommodating a volume of liquid in a range of approximately 8 oz to approximately 32 oz. Likewise, the drinking reservoir  3  must be of an adequate size to meet the user&#39;s needs. The drinking reservoir  3  is not limited to, but is capable of safely accommodating a volume of liquid in a range of approximately 1 oz to approximately 4 oz without risk of spilling. The drinking reservoir  3  comprises a feature for facilitating liquid consumption by the user, such as: a lip, spout, straw, or any other feature that serves a similar function. The pump mechanism  4  comprises an adequate size for displacing the liquid from the holding reservoir  2  to the drinking reservoir  3  with a reasonable amount of effort by the user. The user should be able to initiate movement of the desired amount of liquid to the drinking reservoir  3  by actuating the pump, e.g., in a range of approximately 1 pump to approximately 6 pumps of the pumping mechanism  4 . 
     Referring to  FIG. 1B , this diagram illustrates another perspective view of a vessel  1 , such as a bottle or a container, as shown in  FIG. 1A , in accordance with the present disclosure. The vessel  1  comprises a lower portion  1   a , having a holding reservoir  2 , and an upper portion  1   b , having a drinking reservoir  3 , a closable spout  5 , and a pump mechanism  4 . The holding reservoir  2  is used to store the bulk of the liquid. When a user (not shown) desires, the user will use the accompanied pump mechanism  4  to move the liquid into the drinking reservoir  3  which accommodates a volume of liquid that is less than the maximum volume capacity of the holding reservoir  2 . Once the liquid (not shown) is disposed in the drinking reservoir  3 , the user may consume the liquid when it meets the user&#39;s specific preferences. 
     Referring to  FIG. 2 , this diagram illustrates a cross-sectional view of a vessel  1 , in accordance with another embodiment of the present disclosure. The vessel  1  comprises a lower portion  1   a , having a holding reservoir  2 , and an upper portion  1   b , having a drinking reservoir  3 , a closable spout  5 , and a pump mechanism  4 . The holding reservoir  2  is used to store the bulk of the liquid. When a user (not shown) desires, the user will use the accompanied pump mechanism  4  to move the liquid into the drinking reservoir  3  which accommodates a volume of liquid that is less than the maximum volume capacity of the holding reservoir  2 . Once the liquid (not shown) is disposed in the drinking reservoir  3 , the user may consume the liquid when it meets the user&#39;s specific preferences. The pump mechanism  4  comprises a pump membrane  4   a , a pump air inlet  6 , a pump air inlet valve  7 , a pump air outlet  8 , and a pump air outlet valve  9 . The vessel  1  further comprises a removable liquid dispensing tube  10  for facilitating liquid communication between the holding reservoir  2  and the drinking reservoir  3 . The vessel  1  further comprises a seal  11 , such as a circular seal, disposed between the lower portion  1   a  and the upper portion  1   b.    
     Still referring to  FIG. 2 , in further detail, the holding reservoir  2  is of a size to hold an amount of liquid adequate for an individual consuming their beverage of choice and may be of any shape that meets a user&#39;s demands, such as: as bag, a box, or other shaped container. The size of the holding reservoir  2  is not limited, but is capable of accommodating a volume of liquid in a range of approximately 8 oz to approximately 32 oz. Likewise, the drinking reservoir  3  must be of an adequate size to meet the user&#39;s needs. The drinking reservoir  3  is not limited to, but is capable of safely accommodating a volume of liquid in a range of approximately 1 oz to approximately 4 oz without risk of spilling. The drinking reservoir and cap  3  may have a structure for the user to consume the liquid easily, such as: a lip, spout, straw, or any other device that serves a similar function. The pump membrane  4   a  is of adequate size to cause the desired amount of liquid to move from the holding reservoir  2  to the drinking reservoir  3  in approximately 1 pump to approximately 6 pumps. The pump membrane  4   a  comprises at least one of a rubber, a flexible polymer, or any other material, such as an elastic material, that would provide the proper functionality. 
     Still referring to  FIG. 2 , the seal  11  prevents leakage between the lower portion  1   a  and the upper portion  1   b . The lower portion  1   a  and the upper portion  1   b  may coupled together by any technique, such as coupling by way of threaded surfaces, by way of an interference fit, and the like. The overall size of vessel  1  may be of a similar size to other containers holding a similar amount of liquid. When desired, the user depresses the pump membrane  4   a , which causes a positive pressure that is forced down the pump outlet  8  and through the pump outlet valve  9 , thereby increasing pressure in the holding reservoir  2  displacing and forcing liquid up the removable liquid dispensing tube  10  and out the closable spout  5 . The closable spout  5  comprises a latch mechanism. The liquid is then collected in the drinking reservoir  3 . Once the user removes pressure from the pump membrane  4   a , the pump membrane  4   a  reverts to its original form, whereby a negative pressure is effected in the pump membrane  4   a , thereby activating the pump air inlet valve  7 , thereby allowing air to pass through the pump air inlet  6 . The inflow of air from the pump air inlet  6  fills the pump membrane  4  and equalizes the pressure gradient. Once one cycle is complete, the user may repeat the action until the desired amount of liquid has filled the drinking reservoir  3 . 
     Referring to  FIG. 3A , this diagram illustrates a cutaway cross-sectional view of a sealing mechanism, such as closable spout  5  on a liquid exit  18  to a drinking reservoir  3  of the upper portion  1   b , such as a lid, of a vessel  1  in an open configuration, in accordance with an embodiment of the present disclosure. The closable spout  5  comprises a closable flap  12 , an opening lever  13 , a sealing valve  14 , a closable push point  15 , a closable flap latch  16 , a lid latch point  17 , and a closable flap pivot point  19 . The closable spout  5  seals the liquid exit  18  of the upper portion  1   b  and also serves to deflect incoming liquid from the liquid exit  18 , thereby preventing splashing liquid on the user. 
     Still referring to  FIG. 3A , when the user desires to close the container  1 , the user will push down on the closable push point  15 , thereby disposing the sealing valve  14  in relation to the liquid exit  18 , and thereby disposing the closable flap latch  16  in relation to the lid latch point  17 . The closable flap latch  16  will hold the closable flap  12  in place and insure a seal between the sealing valve  14  and the liquid exit  18 . In operating the vessel  1 , the user will push on the opening lever  13 , thereby releasing the closable flap latch  16  from the lid latch point  17 , thereby releasing the sealing valve  14  from the liquid exit  18 , and thereby allowing liquid to therethrough flow. In this configuration, the closable flap  12  also provides an adequate amount of protection so that the liquid from the liquid exit point  18  will be channeled into the drinking reservoir  3  without splashing the user. During the opening and closing cycles of the closable spout  5 , the closable flap  12  will pivot about the closable flap pivot point  19 . The closable spout  5  comprises a material having a rigidity, strength, and flexibility that is conducive to long-term cycling of the opening and closing action, such as at least one of a plastic, a composite, or a metal. The sealing valve  14  comprises a flexible material conducive to sealing the liquid exit  18 , such as a rubber or any other flexible polymer. 
     Referring to  FIG. 3B , this diagram illustrates a cutaway cross-sectional view of a sealing mechanism, such as closable spout  5  on a liquid exit  18  to a drinking reservoir  3  of the upper portion  1   b , such as a lid, of a vessel  1 , as shown in  FIG. 3A , in a closed configuration, in accordance with an embodiment of the present disclosure. The closable spout  5  comprises a closable flap  12 , an opening lever  13 , a sealing valve  14 , a closable push point  15 , a closable flap latch  16 , a lid latch point  17 , a liquid exit  18 , and a closable flap pivot point  19 . The closable spout  5  seals the liquid exit  18  and also serves to deflect incoming liquid from the liquid exit  18 , thereby preventing splashing liquid on the user. 
     Example 2 
     Embodiment with an Automatically Closable Spout 
     Referring to  FIG. 4A , this diagram illustrates a perspective view of a vessel  1  with a pump membrane  4   a  and an automatically closable spout  21 , in accordance with an embodiment of the present disclosure. The vessel  1  comprises a lower portion  1   a , having a holding reservoir  2 , and an upper portion  1   b , having a drinking reservoir  3 , an automatically closable spout  21 , and a pump mechanism  4 . 
       FIG. 4B  is a diagram illustrating another perspective view of a vessel  1  with a pump membrane  4   a  and an automatically closable spout  21 , as shown in  FIG. 4A , in accordance with an embodiment of the present disclosure. The vessel  1  comprises a lower portion  1   a , having a holding reservoir  2 , and an upper portion  1   b , having a drinking reservoir  3 , an automatically closable spout  21 , and a pump mechanism  4 . 
     Referring to  FIG. 5 , this diagram illustrates a cross-sectional view of a vessel  1  with a pump mechanism  4  and an automatically closable spout  21 , as shown in  FIG. 4A , in accordance with an embodiment of the present disclosure. The vessel  1  comprises a lower portion  1   a , having a holding reservoir  2 , and an upper portion  1   b , having a drinking reservoir  3 , an automatically closable spout  21 , and a pump mechanism  4 . The pump mechanism  4  comprises a pump membrane  4   a , a pump air inlet  6 , a pump air outlet  8 , a pump air outlet valve  9 , and a seal  11 . The vessel  1  further comprises a removable liquid tube  10 , such as a straw, for facilitating liquid communication between the holding reservoir  2  and the drinking reservoir  3 . The vessel  1  further comprises a seal  11 , such as a circular seal, disposed between the lower portion  1   a  and the upper portion  1   b.    
     Still referring to  FIG. 5 , the pump mechanism  4 , comprising a membrane pump  4   a , fits into a receiving depression RD. As the user depresses the pump membrane  4   a , a positive pressure is created inside, which pushes the pump membrane  4  against the edges of the receiving depression RD in the drinking reservoir  3 , which further sealing the pump membrane  4   a . When desired, the user will depress the pump membrane  4 , which causes a positive pressure through the pump outlet  8  and through the pump outlet valve  9 , thereby increasing pressure in the holding reservoir  2 . Once the user removes pressure from the pump membrane  4   a , the pump membrane  4   a  returns to its original form. This causes a negative pressure in the pump membrane  4   a , which activates the inlet valve  7  associated with the automatically closable spout  21 , thereby allowing gas, such as air, to pass through the pump air inlet  6 . The inflow of air (not shown) from the pump air inlet  6  fills the pump membrane  4   a , thereby equalizing the pressure gradient. Because the automatically closable spout  21  rests in the closed position, the increased pressure in the holding reservoir  2  remains until the user opens the automatically closable spout  21 , thereby allowing the internal pressure to force liquid to travel up the liquid dispensing tube  10  and into the drinking reservoir and cap  3 . Opening the automatically closable spout  21  will be discussed further in the following paragraphs. The user may repeat this process until the desired amount of liquid has filled the drinking reservoir  3 . 
     Referring to  FIG. 6A , this diagram illustrates a cutaway cross-sectional view of an automatically closable spout  21  to a drinking reservoir  3  of the upper portion  1   b  of a vessel  1  in an open configuration, in accordance with an embodiment of the present disclosure. The pump mechanism  4  comprises the pump membrane  4   a . The automatically closable spout  21 , shown here in the closed position, comprises a depressor valve  23 , the spout rod  24 , and the spout deflector seal  25 . The upper portion  1   b  comprises a gas inlet  6 , the gas outlet  8 , and the liquid exit  18 . In further detail, the spout rod  24  comprises a length such that a tension is effected between the depressor valve  23  and the spout deflector seal  25  by slightly deforming the spout deflector seal  25 . This also ensures an airtight seal from both ends of the automatically closable spout  21 . When the user desires liquid in the drinking reservoir  3 , the user will push the pump membrane  4   a  which actuates the depressor valve  23 , thereby deploying the automatically closable spout  21  into the open position. 
     Referring to  FIG. 6B , this diagram illustrates a cutaway cross-sectional view of an automatically closable spout  21  to a drinking reservoir  3  of the upper portion  1   b  of a vessel  1 , as shown in  FIG. 6A , now in the open configuration, in accordance with an embodiment of the present disclosure. The pump mechanism  4  comprises the pump membrane  4   a . The automatically closable spout  21 , shown here in the open position, comprises a depressor valve  23 , the spout rod  24 , and the spout deflector seal  25 . The upper portion  1   b  comprises a gas inlet  6 , the gas outlet  8 , and the liquid exit  18 . In further detail, a positive pressure is effected in the holding reservoir  2  by pressing the pump membrane  4   a , thereby actuating the depressor valve  23 , thereby moving the spout rod  24  away from the pump membrane  4   a , thereby moving the spout deflector seal  25  away from a wall  3   a  of the drinking reservoir  3 , and thereby allowing liquid to travel up the liquid dispensing tube  10  and through the liquid exit  18 . The spout deflector seal  25  comprises a shape, e.g., a semi-toroid shape, a convex flange, and the like, such that the liquid spray is captured and redirected (deflected) into the drinking reservoir  3 . The membrane depressor valve  23  and the spout deflector seal  25  each comprise a material having adequate necessary flexibility, elasticity, and sealing characteristics, such as a rubber, a flexible polymer, or a flexible composite material. The spout rod  24  comprises a rigid material, such as a plastic, a rigid composite material, a metal, a metal alloy. 
     Referring to  FIG. 7 , this diagram illustrates an exploded cutaway cross-sectional view of an automatically closable spout  21  and a pump membrane  4   a  coupled with an upper portion  1   b  of a vessel  1 , in accordance with an embodiment of the present disclosure. The pump mechanism  4  comprises the pump membrane  4   a  and the automatically closable spout  21 . The upper portion  1   b  comprises the pump air inlet  6 , the pump air outlet  8 , and the liquid exit  18 . The automatically closable spout  21  comprises a depressor valve  23 , a spout rod  24 , and a spout deflector seal  25 . The automatically closable spout  21  is shown in a disassembled state. In further detail, the automatically closable spout  21  can be fabricated by disposing the spout rod  24  and the spout seal deflector  25  in relation to an orifice O of the upper portion  1   b , disposing the depressor valve  23  in a receiving slot RS of the upper portion  1   b , disposing a distal end of the spout rod  24  into a receiving portion RP of the depressor valve  23 , whereby the distal end of the spout rod  24  is retained by a technique, such as an interference fit, and the pump membrane  4   a  is disposed in a receiving feature RF of the upper portion  1   b , whereby the pump membrane  4   a  is also retained by a technique, such as an interference fit. The foregoing configuration for the pump mechanism  4  facilitates disassembly and reassembly of the components, thereby facilitating cleaning of the passageways, e.g., the gas and liquid passageways of the upper portion  1   b  of the vessel  1 . 
     Some further benefits of the vessel  1  include, but are not limited to, minimizing a risk of spilling the bulk of a liquid disposed in the holding reservoir  2  while providing features that facilitate consumption of the liquid, and facilitating cooling only a small amount of the liquid at a time in the drinking reservoir  3  while maintaining the temperature of the bulk of a heated liquid, such as coffee or tea, for a longer period of time in the holding reservoir  2 , providing extended thermal maintenance of the liquid in the holding reservoir  2  by way of an insulated embodiment of the vessel  1 , providing easy drinkability by way of a simple mug configuration, travel mug configuration, desk mug configuration, or other appropriate drinking vessel configuration, facilitating fabrication by using a low number of parts, and facilitating cleaning by providing easy cleanability of the liquid and gas passageways by way of ready disassembly and reassembly of the low number of parts having easy coupling feature, such as an interference fit, for quick connect and quick disconnect. 
     In a general embodiment, the vessel  1  comprises a holding reservoir  2  that has a large volume for containing the bulk of a liquid, a drinking reservoir  3  that has a smaller volume for short term storage and consumption, and a transportation mechanism that moves the liquid from the holding reservoir  2  to the drinking reservoir  3 . The transportation mechanism is contemplated by the present disclosure to include a pump mechanism  4 , having a pump membrane  4   a , that facilitates proper cleaning, thereby providing a sanitary vessel  1 , and thereby minimizing the risk of food poisoning or the transmission of other infections to the user. The pump mechanism  4  contains fewer moving parts, has a smaller size, is less likely to inadvertently engage other objects, and is less likely to break than related art drinking vessel components. 
     Also contemplated by the present disclosure is the disposition of the pump membrane  4   a  in relation to the upper portion  1   b  for providing an ergonomic feature for the user, e.g., the vessel  1  facilitates single-handed operation of the pump mechanism  4  and facilitates redisposing the upper portion  1   b  in relation to the lower portion  1   a  after refilling the holding reservoir  2  with a liquid, e.g., a beverage, when transposing the upper portion  1   b  in relation to a lower portion  1   a  (with full pumping functionality) of any other vessel  1 , or when retrofitting the upper portion  1   b  to any other interfaceable preexisting drinking vessel by way of a technique, such as a complimentary threading and an interference fit. 
     Furthermore, in an embodiment of the vessel  1 , comprising the automatically closable spout  21 , hot liquids are prevented from spraying or splashing the user during operation by automatically sealing (undeployed state) and deflecting the liquid into the drinking reservoir  3  during filling (deployed state). Easy removal of the components of the pump mechanism  4  facilitates cleaning of the gas and liquid passage ways and help to reduce the risk of trapped hazardous materials, such as contaminants and pollutants, as well as trapped biohazardous materials, such as germs, e.g., bacteria, viruses, and the like.
