the exemplary embodiments of the present invention are described and illustrated below as a fluid container , referred to below as a “ sippy straw cup ”, comprising a cup and corresponding lid having a sliding actuator to regulate fluid communication between an interior of the sippy straw cup and an external environment . the various orientational , positional , and reference terms used to describe the elements of the present invention are therefore used according to this frame of reference . however , for clarity and precision , only a single orientational or positional reference will be utilized ; and , therefore it will be understood that the positional and orientational terms used to describe the elements of the exemplary embodiment of the present invention are only used to describe the elements in relation to one another . referring to fig1 and 2 , an exemplary embodiment of a sippy straw cup 10 includes a cup 12 , a lid 14 , a sliding actuator 16 , and a straw 18 providing a selectively sealed fluid reservoir 20 available for holding a fluid therein , that may include , without limitation , a beverage . in an open position , as shown , the straw 18 is erect and provides fluid communication between the fluid reservoir 20 and an external environment 22 . the straw 18 may include two or more sections , with a first section 24 being resilient and a second section 26 coupled to the first section 24 that is less resilient and not readily amendable to spatial deformation . referencing fig2 - 4 , the cup 12 includes a cavity 28 partially defined by an exterior wall 30 of an inner cup 32 and partially by an interior wall 34 of an outer cup 36 . the cavity 28 may be adapted to receive a graphical expression ( not shown ), in which case the outer cup may be transparent to facilitate visual appeal . the graphical expression may include a lenticular or holographic image on a medium positioned within the cavity 28 . those of ordinary skill in the art are familiar with the methods of forming lenticular , holographic , or other images onto various mediums . the inner cup 32 includes an interior wall surface 38 defining the reservoir 20 and a spout 40 having spiral protrusions 42 on an exterior surface 44 adapted to be received within corresponding grooves 70 within the lid 14 for securing the lid 14 to the cup 12 . the spout 40 includes a ledge 46 transitioning into a circumferential wall 48 forming a recess 50 between the circumferential wall 48 and the exterior wall 30 of the inner cup 32 . the recess 50 is adapted to receive a top portion 52 of the outer cup 36 , where the outer cup 36 and the inner cup 32 may be coupled together by spin sealing . the outer cup 36 transitions from the top portion 52 into a sill 54 circumferentially thereabout that tapers inward to create a first indentation 56 . the first indentation 56 leads into a first mound 58 that gives rise to a second indentation 60 and thereafter a second mound 62 . each indentation 56 , 60 and each mound 58 , 62 is circumferentially distributed about the outer cup 36 . the second mound 62 transitions into a smooth taper terminating at a bottom aspect 64 having a dome shaped underneath surface 66 . referencing fig5 - 8 , the lid 14 is substantially domed shaped having a plurality of raised areas 68 circumferentially distributed thereabout to facilitate gripping as the corresponding grooves 70 within an outer wall 72 receive the spiral protrusions 42 of the inner cup 32 to couple the lid 14 to the cup 12 ( see fig1 ). a fluidic seal is created between an interior surface 74 of the outer wall 72 and the exterior surface 42 of the inner cup 32 , as well as between an interior surface 76 of an inner lip 78 ( extending from the outer wall 72 ) and the interior surface 38 of the inner cup 32 . the outer wall 72 transitions upward from the inner lip 78 in an arcuate manner until terminating at a recess 80 . the recess 80 includes a side surface 82 being essentially square with an arcuate top surface 84 . the arcuate top surface 84 defines an orifice 86 therein and gives rise to a conduit 88 extending from the top arcuate surface 84 of the recess 80 to an underneath surface 90 of the lid 14 . the conduit 88 includes circumferential projection 92 separating a first cylindrical portion 94 and a second cylindrical portion 96 having a greater diameter than the first cylindrical portion 94 . a groove 97 , adapted to receive the straw 18 , is formed within the recess 80 and includes a finger 98 abutting the orifice 86 . the side surface 82 of the recess 80 includes a guide notch 100 cut therein following the generally arcuate shape of the recess that is adapted to receive guide pins 102 of the sliding actuator 16 ( see fig9 - 11 ). referring to fig9 - 12 , the sliding actuator 16 is adapted to be received within the recess 80 and includes a generally arcuate shape from the side , where an underneath surface 104 is adapted to ride along the top surface 84 of the recess 80 and a top surface 106 of the actuator 98 is adapted to be substantially flush with the outer wall 72 of the lid 14 upon being seated within the recess 80 . two guide pins 102 protrude from each side 108 of the actuator 16 and are operative to guide the actuator 16 within the recess 80 from a closed position where the straw 18 is wedged between the underneath surface 104 and the top surface 84 and an open position where the straw 18 is erect . a contoured ridge 110 extends across the actuator 16 and includes two sliding guides 112 adapted to slide along the outer wall 72 . the contoured ridge 110 provides an actuation point for a user to push against or pull on the ridge 110 to effect motion of the actuator 16 with respect to the recess 80 . the underneath surface 104 includes a pair of rectangular projections 113 forming a mating channel 114 therebetween . the front 116 of the actuator 16 is partially open to guide the cylindrical nature of the straw 18 into the mating channel 114 when the actuator 16 is in the closed position . the straw 18 may include exterior features such as guide grooves or ridges ( not shown ) to further facilitate alignment within the groove 97 and the mating channel 114 . referencing fig1 , the open position of the sippy straw cup 10 is shown having the first section 24 of the straw 18 partially received within the conduit 88 and includes an exposed section 120 with a tip 122 at the end not received within the conduit 88 . an orifice 124 defined by a wall 126 of the straw 18 provides a generally constant internal diameter providing a circular cross - sectional area available for fluid flow therethrough . this generally constant internal diameter continues for the length of the first cylindrical portion 94 and part of the second cylindrical portion 96 . the radius of orifice 124 and the radius of the wall 126 aggregate to approximate the internal diameter of the conduit 88 . the straw 18 includes an indentation 128 that receives the circumferential projection 92 seating the straw 18 within the conduit 88 . the wall 126 increases in thickness to abut an interior wall 130 of the second cylindrical portion 96 , and when teamed with the indentation 128 and the circumferential projection 92 , inhibits vertical movement of the straw 18 within the conduit 88 . just beyond the exit of the conduit 88 , a step change within the straw is present where the orifice 124 increases in cross - section to receive the second section 26 adapted be in direct contact with the beverage occupying the reservoir 20 of the sippy straw cup 10 . referring to fig1 , the closed position of the sippy straw cup 10 is shown having the straw 14 wedged between the underneath surface 104 of the actuator 16 and the top surface 84 of the recess 80 . in practice , as the actuator 16 is repositioned from the open position to the closed position , the front 116 of the actuator 16 contacts the external wall 126 of the exposed section 120 of the straw 18 and pushes the straw forward . the open section of the front 116 of the actuator 16 and the mating channel 114 receives the exposed section 120 of the straw 18 as the actuator 16 continues moving forward , thereby pushing the straw 18 over the finger 98 projecting outward from the conduit 88 and into the groove 97 formed within the recess 80 . as the straw 18 is received within the groove 97 and mating channel 114 , the finger 98 forces one side of the straw wall 126 against the other side of the straw wall 126 , discontinuing the orifice 124 within the straw 18 to inhibit fluid communication between the second section 26 and the tip 122 of the straw 18 . the forward movement of the actuator 16 pushes the straw 18 completely within the groove 97 and mating channel 114 while the rear section 118 of the actuator 16 covers the orifice 86 . when moving from the closed to the open position , the actuator 16 is moved backward , gradually uncovering the exposed section 120 of the straw 18 previously seated within the groove 97 and mating channel 114 such that the resiliency of first section 26 of the straw 18 gradually raises the straw 18 to an erect position abutting the front 116 of the actuator 16 . following from the above description and invention summaries , it should be apparent to those of ordinary skill in the art that , while the methods and apparatuses herein described constitute exemplary embodiments of the present invention , the inventions contained herein are not limited to these precise embodiments and that changes may be made to them without departing from the scope of the invention as defined by the claims . additionally , it is to be understood that the invention is defined by the claims and it is not intended that any limitations or elements describing the exemplary embodiments set forth herein are to be incorporated into the meanings of the claims unless such limitations or elements are explicitly recited in the claims . likewise , it is to be understood that it is not necessary to meet any or all of the identified advantages or objects of the invention disclosed herein in order to fall within the scope of any claim , since the invention is defined by the claims and since inherent and / or unforeseen advantages of the present invention may exist even though they may not have been explicitly discussed herein .
