Figures 1-4 illustrate a first embodiment of a lid assembly of the present invention. Figure 1 illustrates that a container 100 comprising a base member 102, a lid assembly 104 on top of the base member 102. The base member 102, for example, is cylindrical in profile and is configured to contain liquid such as water. The cross section, in traverse plane, of the lid assembly 104 is sized and shaped corresponds to the cross section, in traverse plane, of the base member 102, and thus the lid assembly 104 is assembled on top of the base member 102 by common closure means such as screw closure or quick-fit well known in the art. For brevity purpose, the closure means is well understood by those skilled in the art and thus is not explained in details herein. The lid assembly 104 comprises a lid body 106 and a cover body 108. The cover body 108, for example, is profiled in a ring shape having an arcuate notch, thus the cover body 108 is provided with two opposite ends 108A, 108B at the notch thereof. Said two opposite ends 108A, 108B pivotably engaged with the lid body 106 allows the cover body 108 to move pivotably about an axle. Pivotal engagement between the lid body 106 and the cover body 108 will be described subsequently in greater details. As seen, the substantial central portion of the cover body 108 is hollow, therefore, when the cover body 108 sits on the lid body 106, as illustrated in Figure 1, the upper surface (or the top surface) of the lid body 106 can be seen by naked eyes. The pivotal movement of the cover body 108 with respect to the lid body 106 can be seen clearly in a closer view of the lid assembly 104 illustrated in Figures 2A and 2B. For brevity’s sake, figure 2B shows the assembly with some parts of the lid body 106 and the cover body 108 remove. Said pivotal movement, for example, is embodied by respective connection between the two opposite ends 108A, 108B and plateaus 109A, 109B. Referring to figure 2B, it can be seen that the plateaus 109A and 109B each is a standing wall in a recessed area provided on the perimeter of the top side of the lid body 106, wherein the recessed area is distant from the lock 112. The opposite ends 108A, 108B and plateaus 109A, 109B are internally provided with a groove defining an aperture 110 for receiving an axle (for brevity’s sake, the axle is not shown in figures) for allowing the pivotal movement of the cover body 108 with respect to the lid body 106. Advantageously, in a manufacturing process, the axles are metal pins respectively arranged penetrating through the two opposite ends 108A, 108B and plateaus 109A, 109B. Figure 3A-C illustrate the lid assembly 104 is in different configurations, in which figure 3A illustrates the cover body 108 is locked, figure 3B illustrates the cover body 108 is unlocked, and figure 3C illustrates the cover body 108 is fully opened Referring to figure 3A, it can be seen that a lock 112 is provided to the lid assembly 104. When the lock 112 is open, the cover body 108 is allowed to move away or towards the lid body 106 about the axles penetrating through the two opposite ends 108A, 108B and plateaus 109A, 109B. When the lock 112 is closed, it restricts the movement of the cover body 108 about the axles and the cover body 108 is secured on top of the lid body 106. As an illustrative example in figures 3A and 3B, the lock 112 comprises a tongue 112A pivotably connected to the cover body 108 about axles 112B, 112C, and a hook 112D provided to the outer circumferential wall of the lid body 106. The operation of the lock 112, for example, can be implemented by an interlocking relationship between the tongue 112A and the hook 112D by hingedly moving the tongue 112A towards the hook 112D about the axles 112B, 112C, when the tongue 112A abuts the hook 112D, the tongue 112A and the hook 112D can be interlocked, for example by snap fitting, by snapping the tongue 112A slightly further against the hook 112D. When the lock 112 is required to be unlocked, it can be implemented by snapping the tongue 112A slightly away from the hook 112D to release the interlocking between the two members, by then the cover body 108 can be moved freely about the axles. Operation of the lock 112 can be referred to figures 3A-C. Advantageously, the tongue 112A or the hook 112D, for example, is prepared with resilient materials, allowing easier the interlocking between the two members. The lid assembly 104 further comprises an orifice 120, as shown in figure 3C which shows that the cover body 108 is opened 180° degrees from its locked configuration. As shown, the orifice 120 is exposed and thus be seen at the edge of the upper surface of the lid body 106. By definition, “upper surface of the lid body” in the context of this aspect of invention refers to the outwardly facing surface of the lid body 106 when the lid body 106 is assembled to the base member 102. Advantageously, the orifice 120 is suitable for drinking hot liquid contained in the base member 102, since the orifice 120 is dimensioned small thus the flow rate of the hot liquid can be controllably adjusted. The orifice 120 is provided with a dispensing system operably connecting the orifice 120 and the internal cavity of the base member 102, allowing user to drink via the orifice 120. For brevity, the dispensing system is well understood by those skilled in the art and thus is not explained in details herein. Figure 3C shows that a protrusion 122 is provided on the underside of the cover body 108. By definition, “underside of the cover body” in the context of this aspect of invention refers to the inwardly facing surface of the cover body 108 when the cover body 108 is locked. The position of the protrusion 122 corresponds to the position of the orifice 120. The orifice 120 is sized and shaped fit to receive the protrusion 122, whereby spilling is prevented when users carrying the container 100. Advantageously. the protrusion 122, for example, is prepared in resilient materials. The lid assembly 104 further comprises a spout 130. The spout 130 is provided with a dispensing system allowing user to drink the beverage in the container via the spout 130. For brevity, the dispensing system is well understood by those skilled in the art and thus is not explained in details herein. Referring to figures 4A-B, it can be seen that the spout 130 is receivable in a chamber 140 formed in the lid body 106. The chamber 140, for example, is defined by a pair of opposite internal walls 140A and 140B of the lid body 106 extending downwards from the upper surface of the lid body 106, the inner surface 140C of the vertical surrounding wall of the lid body 106, and inner surface 140D of the bottom of the lid body 106. By definition, “inner surface of the bottom of the lid body” in the context of this aspect of invention refers to the surface of the bottom of the lid body 106 facing away the internal cavity of the base member 102 when the lid assembly 104 is assembled to the base member 102; and “the inner surface of the vertical surrounding wall of the lid body” in the context of this aspect of invention refers to the inwardly surface of the surrounding wall of the lid body 106. The chamber 140 is dimensioned fit to receive the spout 130. In other words, the shape of the chamber 140 corresponds to the shape of the spout 130. Still referring to figure 4B, as seen, the spout 130 is positioned inside the chamber 140 and is pivotably connected to the lid body 106. For example, the spout 130 is configured to pivotably connect to the pair of opposite internal walls 140A and 140B of the lid body 106 or to pivotably connect to the inner surface 140D of the bottom of the lid body 106. Accordingly, the spout 130 is adapted to assume a first configuration in which the spout 130 is received inside the chamber 140 or a second configuration in which the spout 130 erects substantially perpendicular with respect to the inner surface 140D of the bottom of the lid body 106. Advantageously, as shown in figures 3A-C, the spout 130, for example at its middle portion, is provided with a plate 150 pivotably connected thereat. When the spout 130 is received in the chamber 140 in its first configuration, the plate 150 covers the spout 130, preventing the spout 130 from contaminating from dust. When the spout 130 is received in the chamber 140 in its first configuration, the spout 130 is configured to be sealed or disengaged from the dispensing system by way of, for example, folding the tube in the dispensing system connecting between the spout 130 and the internal cavity of the base member 102 or disengaging the spout 130 from said tube. For brevity purpose, the means for sealing or disengagement is well understood by those skilled in the art and thus is not explained in details herein. Advantageously, as shown in figures 3C and 4A, it can be seen that when the lid body 106 is assembled to the base member 102, the lid body 106 is designed in that the height of the lid body 106 gradually increases from its one end adjacent the axles to its other end adjacent the orifice 120. The design of the lid body 106 provides an advantage that the orifice 120 is in a raised position, providing convenience to users to drink. Meanwhile, when the spout 130 is received in the chamber 140, the lower portion of the spout 130 and the plate 150 lie substantially flat, in particular advantageously lie substantially flat with the center portion of the upper surface of the lid body 106, as illustrated in figures 3A-C. By definition, “the lower portion of the spout” in the context of this aspect of invention refers to the portion of the spout 130 uncovered by the plate 150, and is adjacent to the pivotal connection to the lid body 106. The middle portion of the spout 130 is provided with the plate 150 provides another advantage is that the plate 150 is act as a handle allowing users to pivotally move the spout 130 from its first configuration to its second configuration, thus users do not need to contact the spout 130 for movement by finger(s) or hand. Figures 5-6 illustrate a second embodiment of the lid assembly of the present invention. It illustrates a beverage mug having a lid assembly 300 assembled to a base member. The lid assembly 300 has an outer lid 310, a middle lid 320 and an inner lid 330.
