Drinking container

Abstract

A drinking container is provided that can include a lid member and a cup member. The lid member can include a base member and a spout extending up from the base member. The spout can provide a fluid passageway from outside the drinking container to the volume of the cup member so that a child may drink liquid contained within the cup member. When the lid member is removably coupled to the cup member, two or more seals are created around the circumference of the drinking container between the lid member and the cup member to decrease the likelihood of leakage from between the cup member and the lid member when the lid is coupled to the cup member.

Description

TECHNICAL FIELD

Embodiments disclosed herein are generally related to fluid containers, and more particularly to apparatuses and methods for a drinking container with lid.

BACKGROUND

Conventional drinking cups for children can include removable lids that help prevent large spills or leaks, especially when children are using the cups. These conventional lids are configured to be removable as needed, yet snugly fit to the upper rim of the cup to prevent leakage from the cup when used. These conventional lids can include drinking spouts or openings. Some conventional drinking spouts extend upward from the lid, while other openings may extend out from the lid or be positioned through the lid. The spouts and/or openings can include holes or slots so that when children place their mouths around or adjacent to the spout, they can receive fluids from inside the cup through the hole or slot(s), for example when the cup is tilted and/or inverted. Certain forms of these drinking cups for children are referred to as “sippy cups” or “training cups” (herein collectively referred to as “children's training cup” or “training cup”.

Despite the lids being designed to snugly fit to the lids of the respective children's training cup, spills still occur. Conventional training cups only include one seal between the lid and the cup. Most often, the seal is provided between the upper rim of the cup and a recessed cavity that lines the circumference of the lid. If there are any deformities in either of the lid or the upper rim area of the cup, the single seal may be compromised and leaking can occur. Even without a defect in the lid or the upper rim area of the cup, this conventional cup and lid design that includes only one seal is still susceptible to leaks.

SUMMARY

The present disclosure relates to a drinking container that can provide two or more sealing areas (e.g., circumferential sealing area or sealing points, when viewed in cross-section) between a lid member and a cup member. The lid member can be removably coupled with the cup member. The lid member also can include a spout, similar to those described above, that extends up from a top surface of the lid member. The spout may include one or more holes, slots, or other apertures through which a child may be able to draw liquid from within the cup member. Drawing liquid from the cup member in this way may be limited to when the drinking container is tilted or inverted, or may be possible even when the drinking container is upright.

An upper end of the cup member (which may be shaped and sized in a number of ways) may include a first outward extending step wall extending horizontally or substantially horizontally in a radial direction away from the main side wall of the cup member. A first upper portion wall of the cup member may extend generally upwardly from the first outward extending step wall. Both the first outward extending step wall and the first upper portion wall of the cup member can extend around the circumference of the cup member. A second outward extending step wall can extend outwardly from the top end of the first upper portion wall of the cup member. The second outward extending step wall also can extend around a circumference of the cup member. At the intersection or joint between the first upper portion wall and the second outward extending step wall, a rib or flange member can extend inwardly (e.g. radially inwardly) toward the longitudinal axis of the cup. Additionally, a second ridge or flange member can extend upwardly from the top surface of the second outward extending step wall, and/or a depression, recess, or valley can extend concavely down into the top surface of the second outward extending step wall.

The lid member can include a first downward flange member that extends generally axially downwardly from a bottom surface of the lid member and can define an annular wall along the bottom of the lid member. An outward facing bulb member or protrusion can be positioned on the first downward flange member, and can be enlarged radially outwardly (toward the outside of the cup). The first downward flange member can be positioned at a pre-determined location that allows the bulb member or protrusion to slide along and subsequently abut the inward facing rib or flange member when the lid member and the cup member are selectively engaged with one another. Engaging the first downward flange member of the lid member with the inward facing rib or flange member of the cup member can cause the first downward flange member to deflect radially inwardly in order for the bulb member or protrusion to slide along and past the inward facing rib or flange member. Once the bulb member or protrusion has passed over the inward facing flange member, the first downward flange member resiliently returns to its resting state or to nearly it's resting state. The abutment between the bulb member or protrusion of the first downward flange member and the radially inward facing rib flange member of the cup member forms a first seal (e.g., a first circumferential seal) between the lid member and the cup member.

A second seal can also formed between the cup member and the lid member between a second downward flange member of the lid member, and the ridge or depression positioned along the second outward extending step wall of the cup member. The second downward flange member can extend generally axially downward from a bottom surface of the lid member and can define a second annular wall along the bottom of the lid member. The second downward flange member can be positioned radially outwardly from the first downward flange member. When the lid member and the cup member are removably coupled to one-another, the second downward flange member can abut the ridge and/or fits down into all or a portion of the recess or depression provided along the second outward extending step wall. This can create the second seal (e.g., the second circumferential seal) between the lid member and the cup member.

When the lid member is selectively removably coupled to the cup member, pressure exerted inwardly by the inward facing rib or flange member on the first downward flange can pull the second downward flange into a stronger abutment with the ridge and/or depression. Similarly, pressure exerted outwardly by the ridge and/or depression on the second downward flange, can pull the first downward flange member into a stronger abutment with the inward facing rib or flange member and the first upper portion wall. This can increase the seal strength of each of the first and second circumferential seals between the lid member and cup member.

FIG. 1 is a cross-sectional view of a drinking container 1, in accordance with one example embodiment of the disclosure. Referring now to FIG. 1, the drinking container 1 can include a lid member 3 and a cup member 5. The lid member 3 is configured to be selectively coupled to and decoupled from the cup member 5 (as described in detail herein below).

The cup member 5 can include a bottom surface 51 and one or more side walls 6 extending generally up from the bottom surface 51. In certain example embodiments, the bottom surface 51 can have a generally circular shape or outer perimeter shape. In other example embodiments, the bottom surface 51 can have any other shape including, but not limited to, oval, square, rectangular, another multi-sided geometric shape, or the like.

In one example embodiment, the cup member 5 has a single side wall 6 that extends up from the bottom surface 51 and has a generally circular cross-sectional shape along an axis orthogonal to the vertical axis. In certain example embodiments, the one or more side walls 6 of the cup member 5 can extend vertically or substantially vertically upward, can taper inwardly from top to bottom, can taper outwardly from top to bottom, or any combination thereof. Tapering of the side walls 6 may make the cup member 5 easier for a child to grasp. Other shapes for the cup member 5 are also envisioned herein as would be understood in the art.

The lid member 3 may include a base having a top surface 52 and a bottom surface 53. The lid member 3 can further include a spout 7 extending upwardly from a top surface 52 of the lid member 3 therefrom and integrally formed with the lid member 3. The spout 7 may include one or more holes, slots, or other apertures 49 that, with the spout 7, provide a fluid passageway through which a user, such as a child, may be able to draw liquid from within the cup member 5.

FIG. 2 is a partial cross-sectional view of a portion of an attachment between the cup member 5 and the lid member 3 of the drinking container 1 of FIG. 1, in accordance with one example embodiment of the disclosure. Referring now to FIGS. 1 and 2, the enlarged view more closely illustrates the structure of an upper end 9 of the one or more side walls 6 of the cup member 5. The upper end 9 of each of the one or more side walls 6 can include a first outward extending step wall 11 that extends horizontally or substantially horizontally outward away from the central longitudinal axis Y in a radial direction and away from an upper end 9 of the side wall 6, in one example embodiment. The first outward extending step wall 11 can have a first end coupled to or integrally formed with and extending from upper end of the side wall 6 and a distal second end. In other example embodiments, the first outward extending step wall 11 may extend outwardly away from the central longitudinal axis Y of the cup member 5 with an incline or decline relative to the horizontal. In one example embodiment, the angle of incline or decline from the horizontal can be anywhere in the range of substantially 0 degrees to substantially 45 degrees and more preferably substantially 0 degrees to substantially 20 degrees.

Each of the one or more side walls 6 of the cup member 5 can also include a first upper portion wall 15. The first upper portion wall 15 can include a first end coupled to or integrally formed with the second end of the first outward extending step wall 11 and a distal second end. In one example, the first upper portion wall 15 extends generally upwardly from the first outward extending step wall 11 in a vertical or substantially vertical direction from the second end of the first outward extending step wall 11. In other example embodiments, the first upper portion wall 15 can be tapered inwardly or outwardly from the first end to the second end of the first upper portion wall 15 with respect to a vertical axis.

Each of the first outward extending step wall 11 and the first upper portion wall 15 of the cup member 5 may extend around the circumference of the cup member 5. Further, the upper end 9 of each of the one or more side walls 6, the first outward extending step wall 11, and the first upper portion wall 15 can together define a top surface along the top edge of the first outward extending step wall 11 that is horizontal or substantially horizontal and extends along a horizontal or substantially horizontal axis to create a flat or substantially flat surface.

The first upper portion wall 15 has an inner circumference defined by its inwardly facing surface as it extends around the cup member 5 that is larger than the inner circumference of the inwardly facing surface of the one or more side walls 6 at a point immediately below an intersection of the one or more side walls 6 and the first outward extending step wall 11. Because the first upper portion wall 15 has an inner circumference larger than the inner circumference of the one or more side walls 6 at the point immediately below the intersection of the one or more side walls 6 and the first outward extending step wall 11, the cup member 5 is provided with a somewhat increased volume at the first upper portion wall 15 than if the first upper portion wall 15 had an inner circumference equal to the upper end 9 of the one or more sides 6 at the point immediately below the intersection of the one or more side walls 6 and the first outward extending step wall 11.

As shown in FIG. 2, the first upper portion wall 15 may extend at an angle that is parallel or substantially parallel to the angle of the one or more side walls 6 of the cup member 5. In one example embodiment, the angle can be anywhere within the range of substantially 80 to substantially 110 degrees from a horizontal axis. In alternative embodiments, the first upper portion wall 15 may have an angle different than the angle of the one or more side walls 6 and can be somewhat angled inwardly or outwardly relative to the angle of extension of the one or more side walls 6 of the cup member 5.

The cup member 5 can also include a second outward extending step wall 17 that extends horizontally or substantially horizontally outward in a radial direction away from the central longitudinal axis Y, in one example embodiment. The second outward extending step wall 17 can have a first end coupled to or integrally formed with and extending outward from the second end of the first upper portion wall 15 and a distal second end. In other example embodiments, the second outward extending step wall 17 may extend outwardly with an incline or decline to the horizontal. In certain example embodiments, the angle of extension of the first outward extending step wall 11 is parallel or substantially parallel to the angle of extension of the second outward extending step wall 17.

The second outward extending step wall 17, like the first outward extending step wall 11, extends around the circumference of the cup member 5. In certain example embodiments, the second outward extending step wall 17 increases the circumference of this portion of the cup member 5 relative to the first upper portion wall 15 and the upper end of the one or more side walls 6 of the cup member 5. In alternative embodiments, the second outward extending step wall 17 may extend outwardly from the second end of the first upper wall portion 15 in an inclined or declined direction relative to the horizontal. In one example embodiment, the angle of incline or decline from the horizontal can be anywhere in the range of substantially 0 degrees to substantially 45 degrees and more preferably substantially 0 degrees to substantially 20 degrees.

The cup member 5, can also include a radially inwardly extending circumferential rib or flange member 19 that extends inwardly (toward the longitudinal axis Y) from the second end of the first upper portion wall 15 adjacent to the intersection between the first upper portion wall 15 and the second outward extending step wall 17. The rib or flange member 19 can extend circumferentially along the inner circumference of the first upper portion wall 15. The radially inwardly extending rib or flange member 19 may have a rounded inner facing wall (the wall closest to the longitudinal axis Y), or may be any other suitable shape as would be understood by those of ordinary skill in the art. The example rib or flange member 19 creates a smaller inner circumference at the inner wall of the rib or flange member 19 than the inner circumference of the inner surface of the rest of the first upper portion wall 15 of the cup member 5.

FIG. 2 also illustrates a portion of the lid member 3 in greater detail. As shown in FIG. 2, the lid member 3 can further include a first downward flange member 21 that extends downwardly in a vertical or substantially vertical direction from a bottom surface 53 of the lid member 3. The first downward flange member 21 can include a first end and a distal free end. The first end of the first downward flange member 21 can be coupled to or integrally formed with the bottom surface 53 of the lid member 3. In one example, the first downward flange member 21 defines an annular ring or wall that extends axially down from the bottom surface 53 and extends circumferentially along the bottom surface 53 of the lid member 3 in a circular or substantially circular manner. Alternatively, multiple first downward flange members 21 may be provided along the bottom surface 53 of the lid member 3, each first downward flange member 21 being a discrete flange that that extends axially down from the bottom surface 53 but is not continuously extending circumferentially along the bottom surface 53 of the lid member 3. The multiple first downward flange members 21 may be positioned equidistantly or randomly along a circumferential path along the bottom surface 53 of the lid member 3. In one example, the first downward flange member 21 is integrally formed with the lid member 3.

In some example embodiments, an outward facing bulb member or protrusion 23 is provided along a radially exterior-facing side of the free end of the first downward flange member 21. The example outward facing bulb member or protrusion 23 can be integrally formed with the first downward flange member 21 and causes the free end of the first downward flange member 21 or a portion adjacent thereto to have a greater width than the remainder of the member 21 and to be enlarged radially outwardly (toward the outer perimeter of the lid member 3) that creates a larger outer circumference along the part of the member 21 having the bulb member or protrusion 23 than the rest of the first downward flange member 21. In certain example embodiments, the first downward flange member 21 can be positioned at a pre-determined location along the bottom surface 53 of the lid member 3 that allows the bulb member or protrusion 23 of the first downward flange member 21 to slide along an interior side of and subsequently abut the radially inwardly extending rib 19 of the cup member 5 when the lid member 3 and the cup member 5 are removably coupled to one another. When the lid member 3 engages with the cup member 5 as they are being removably coupled to one-another, at least a portion of the flange member 21 deflects radially or substantially radially inwardly in order for the bulb member or protrusion 23 to slide along and past the inward extending rib or flange member 19. Once the bulb member or protrusion 23 has been slid passed the rib or flange member 19, the first downward flange member 21 resiliently returns to its resting state or to nearly it's resting state as will be discussed below.

As shown in FIG. 2, when the outward facing bulb member or protrusion 23 abuts the inwardly extending rib or flange member 19, a first seal 27 (e.g., a first circumferential seal) is formed between the bulb member or protrusion 23 of the first downward flange member 21 and the radially inwardly extending rib or flange member 19 of the cup member 5. The first seal 27 is configured to act as a fluid seal between the lid member 3 and the cup member 5 to help to retain liquid within the cup member 5 and prevent leaks and/or spills. The resiliency or spring-biasing force of the first downward flange member 21 and the positioning of the bulb member or protrusion 23 below or immediately below the radially inwardly extending rib or flange member 19 to contact the first upper portion 15 below or immediately below the rib or flange member 19, allows the first seal 27 to resist removal of the lid member 3 from the cup member 5

A second seal 29 (e.g., a second circumferential seal) can also be formed between the cup member 5 and the lid member 3. For example, the lid member 3 can include a second downward flange member 31 extending downwardly in a vertical or substantially vertical direction from the bottom surface 53 of the lid member. The second downward flange member 31 can include a first end and a distal free end. The first end of the second downward flange member 31 can be coupled to or integrally formed with the bottom surface 53 of the lid member 3. In one example, the second downward flange member 31 defines an annular ring or wall that extends axially down from the bottom surface 53 and extends circumferentially along the bottom surface 53 of the lid member 3 in a circular or substantially circular manner. As shown in FIG. 2, the second downward flange member 31 may be positioned radially outwardly from the first downward flange member 21 along the bottom surface 53 of the lid member 3. The second downward flange member 31 may not extend as far downwardly as the first downward flange member 21 (e.g., the axial length of the second downward flange member 31 can be shorter than the axial length of the first downward flange member 21), as is shown in FIG. 2. In some alternative example embodiments, rather than a single annular ring, multiple second downward flange members 31 may be provided along a circular path, wherein each of the second downward flange members 31 may be a discrete flange member that does not encircle the lid member 3.

To engage with the second downward flange member 31, the second outward extending step wall 17 may include a ridge 33 and/or a depression 35 disposed along its top surface and provided around its full circumference or in discrete locations. While the second outward extending step wall 17 can include a substantially flat and/or horizontal top surface, the ridge 33 can extend to a height above the remainder of the substantially flat top surface (similar to a bump or hill) of the second outward extending step wall 17. In examples where a depression 35 is provided, the depression 35 can be a recess or indentation along the substantially flat and/or horizontal top surface that extends below the level of the substantially flat and/or horizontal top surface of the second outward extending step wall 17.

The second downward flange member 31 may be positioned and located on the lid member 3 to abut the ridge 33 and/or fit down into the depression 35 of the second outward extending step wall 17 when the lid member 3 is removably coupled to the cup member 5. When the second downward flange member 31 and the ridge 33 and/or depression 35 abut one another, as shown in FIG. 2, a second seal 29 between the cup member 5 and the lid member 3 is created.

As noted above, when the lid member 3 is removably coupled to the cup member 5, the rib or flange member 19 may press inwardly on the first downward flange member 21, and/or the first upper portion wall 15 may press inwardly on the bulb member or protrusion 23. As a result, the first downward flange member 21 applies a radially outward force on the first upper portion wall 15 and/or rib or flange member 19 of the cup member 5, and the first upper portion wall 15 and/or the radially inward extending rib or flange member 19 of the cup member 5 applies a radially inward force on the free end of the first downward flange member 21. At the same time, the second downward flange member 31 applies at least a partially radially inward force on the ridge 33 and/or depression 35, and the ridge 33 or depression applies a radially outward force on the free end of the second downward flange member 31.

Thus, when the lid member 3 is removably coupled with the cup member 5, the first downward flange member 21 and the second downward flange member 31 can provide biasing forces against one another in opposite radial directions. For example, as the first downward flange 21 is forced radially inwardly, it pulls the second downward flange 31 into a stronger abutment with the ridge 33 and/or depression 35. Similarly, as the ridge 33 and/or depression 35 exert radially outward pressure on the second downward flange 31, the first downward flange member 21 is pulled into a stronger abutment with the radially inwardly extending rib or flange member 19 and first upper portion wall 15. This can increase the seal strength of each of the first and second seals 27, 29, and otherwise more securely couples the lid member 3 to the cup member 5.

As will be understood, the structure by which the remainder of lid member 3 and cup member 5 engage may take many forms. As shown in FIG. 2, the cup member 5 can further include a rim 37 that extends generally upward from the second end (e.g., radially outer edge) of the second outward extending step wall 17 and extends substantially around the circumference of the cup member 5 at a top portion thereof. The rim 37 may include each of an inner wall 39 and an outer wall 41 coupled or integrally formed with one-another. The inner wall 39 can include a first end coupled to the second outward extending step wall 17 and can extend generally upwardly to a second end. The outer wall 41 can include a first end coupled to and positioned radially outward from the second end of the inner wall 39 and can extend generally downward from the first end of the outer wall 41 to a second distal free end.

The lid member 3 is also provided with a corresponding rim 43 that is shaped substantially similarly to the rim 37 of the cup member 5. Like the rim 37 of the cup member 5, the rim 43 of the lid member may extend around the entirety of the circumference of the lid member 3. Further, the rim 43 can include each of an inner wall 54 and an outer wall 55 positioned radially outward from the inner wall 54. The inner wall 54 and outer wall 55 can be coupled to each other or the rim 43 can further include a top wall 56 extending between the inner wall 54 and the outer wall 55. The inner wall 54 can include a first end coupled to the top surface 52 of the lid member 3 and can extend generally upwardly from there to a second end. The outer wall 55 can include a first end coupled to and positioned radially outward from the second end of the inner wall 54 and can extend generally downward from the first end of the outer wall 55 to a second distal end. Alternatively, the top wall 56 can include a first end coupled to the second end of the inner wall 54 and a distal second end coupled to the first end of the outer wall 55. As shown in FIG. 2, when the lid member 3 and the cup member 5 are removably coupled to one another, the rims 37, 43 may but do not necessarily abut one another and can provide a third seal (e.g. a third circumferential seal) between the lid member 3 and the cup member 5.

As shown in FIG. 2, the lid member 3 may also include a rounded tab hinge 45. The rounded tab hinge 45 may extend outwardly away from the rim 43 and radially outward from the outer wall 55. The rounded tab hinge 45 may extend around all or a portion of the circumference of the lid member 3 and may provide a gripping area by which a user can grip the lid member 3 to hingedly couple and decouple the lid member 3 from the cup member 5, as will be understood to those of ordinary skill in the art. In an alternative embodiment, the rounded tab hinge 45 may be excluded.
