[0003] A fully assembled beverage container 10 is shown in Figures 1-3. Although the beverage container 10 is illustrated as a drinking tumbler, it may also take the form of a glass, mug, cup, goblet, stein, tankard, vessel, beaker, drinkware, beverage container, food container, or other vessel that contains beverages or food for drinking or consumption, with or without a handle, with or without a lid. In addition, although the beverage container 10 is illustrated and described as being for beverages, the container may also be used to contain a number of other substances, materials, or items, such as medicines, oils, flowers (i.e., vases), coins, and keys, and only a few of its many uses may be specified for the container.

[0004] The beverage container 10 has a body 12 that tapers downwards, with an upper end portion 14 wider than the lower end portion 16 and an intermediate portion 18 extending between them. If desired, the beverage container 10 may be constructed of a substantially cylindrical body. The beverage container 10 shown has neither a handle nor a lid, but other forms of the container may include a handle and / or a lid.

[0005] The main body 12 is elongated and has a vertically oriented central axis 20. As shown in Figure 4, the main body 12 has a two-layer structure, with the inner main body 22 positioned inside and within the outer main body 24. The inner main body 22 has an inner main body side wall 26, and the outer main body 24 has an outer main body side wall 28. The inner main body side wall 26 and the outer main body side wall 28 are fully extended and symmetrical with respect to the longitudinal axis 20.

[0006] The inner body 22 has an upper body end 30 at the upper end portion 32 of the inner body and a lower body end 34 at the lower end portion 36 of the inner body. The inner body end wall 38 closes the lower end portion 36 of the inner body 22 so as to define an internal cavity 39 that opens upward to the inner body for holding a beverage or other substance, material, or item (not shown) inside when the beverage container 10 is in an upright position, and engages with the inner body side wall 26 at the lower end portion 36 of the inner body in a fluid seal.

[0007] The outer body 24 has an upper body end 40 at the upper end portion 42 of the outer body and a lower body end 44 at the lower end portion 46 of the outer body. The annular outer body end wall 48 is located at the lower end portion 46 of the outer body 24. The annular outer body end wall 48 has an outer peripheral edge portion 50 and an inner edge portion 52, the inner edge portion defining the central opening 54 of the annular outer body end wall. The peripheral edge portion 50 engages with the outer body side wall 28 at the lower end portion 46 of the outer body 24 for fluid sealing. In a preferred embodiment, the outer body 24, including the annular outer body end wall 48, is formed as a single structure.

[0008] In Figure 4, a flexible elastic stopper 60 is shown detachably positioned within the central opening 54 of the annular outer body end wall 48, and engages fluidly with the inner edge portion 52 of the annular outer body end wall. The stopper 60 is shown removed from the central opening 54 in Figures 5, 6, 11, 12, and 19. Although the inner body side wall 26 and the outer body side wall 28 have a circular cross-section, other shapes may be used for the inner body 22 and the outer body 24. Similarly, although the inner body end wall 38 and the annular outer body end wall 48 are generally circular in shape, they may have other shapes that conform to the shape of the lower end portion 36 of the inner body 22 and the lower end portion 46 of the outer body 24, respectively. The central opening 54 of the annular outer body end wall 48 and the outer circumference of the stopper 60 are also circular in shape, but may have other shapes that conform to them.

[0009] The upper end portion 32 of the inner body 22, located at the upper end 30 of the main body, firmly connects and fluid-seals to the upper end portion 42 of the outer body 24, located at a location 56 below the outer end 40 of the outer body. In the illustrated embodiment, the inner body 22 and the outer body 24 are made of glass, and the firm connection and fluid-sealing engagement are achieved by flame welding the upper end portion 32 of the inner body to the upper end portion 42 of the outer body. In practice, this forms an annular connector portion 61 having an outer edge portion 61a that fluid-seals with the outer body sidewall 28 and an inner edge portion 61b that fluid-seals with the inner body sidewall 26, as shown in Figure 4A before the inner and outer bodies 22 and 24 are firmly connected together, and in Figure 4 after the inner and outer bodies are firmly connected together. A portion 58 of the upper end portion 42 of the outer body 24 extends upward beyond the location 56 where the upper end portion 32 of the inner body 22 connects to the upper end portion of the outer body.

[0010] The inner body end wall 38 that closes the lower end 34 of the inner body 22 is located above the stopper 60 and the annular outer body end wall 48 located at the lower end 44 of the lower end portion 46 of the outer body 24, with a gap between them.

[0011] The internal space 62 is defined on the one hand between the inner body side wall 26 and the inner body end wall 38, and on the other hand between the outer body side wall 28 (at least the portion below location 56), the annular outer body end wall 48, and the stopper 60. The internal space 62 includes a first internal space portion 64 and a second internal space portion 66. The first internal space portion 64 is located around the inner body side wall 26, between the inner body side wall and the outer body side wall 28, and extends circumferentially from location 56 where the upper end portion 32 of the inner body 22 connects to the upper end portion 42 of the outer body 24 to the annular outer body end wall 48. The second internal space portion 66 is located below the inner body end wall 38, between the inner body end wall and the stopper 60. When the stopper 60 is installed, the internal space 62 becomes a hollow fluid-sealed chamber.

[0012] The inner body sidewalls 26 and outer body sidewalls 28, as well as the inner body end wall 38 and the annular outer body end wall 48, are made of hard glass, but may be made of another hard material. Preferably, at least the outer sidewalls 28 are transparent or at least translucent and not opaque. By using glass, a beverage container is provided that is easier to wash and more durable compared to some other materials.

[0013] Regardless of whether it is used to hold beverages or other substances, materials, or items, one use of the beverage container 10 is to give the beverage container a pleasant, informative, or attention-grabbing appearance, or to at least conceal, or completely hide, the contents placed in the internal cavity 39 of the inner body 22 from being seen by a person through the outer body side wall 28 of the beverage container. This is achieved by placing a sheet-like material 68 in the first internal space portion 64 of the internal space 62 (between the inner body side wall and the outer body side wall 28) that conceals or completely hides the contents placed in the internal cavity 39 of the inner body 22 so that they are not visible through the outer body side wall. Although the material 68 is described and illustrated as a sheet-like material, other materials such as confetti, ribbons, and various other materials may be used. Preferably, the material 68 extends circumferentially around the inner body sidewall and longitudinally from the point 56 where the upper end portion 32 of the inner body 22 connects to the upper end portion 42 of the outer body 24 to the annular outer body endwall 48. Preferably, the material 68 is located within the first internal space portion 64, and its side surface 69 is intended to face outward or very close to the inner 28a of the outer body sidewall 28. By using a transparent or at least translucent material, such as glass, for at least the outer sidewall 28, the outward-facing side surface 69 of the material 68, including the texture of the material and any letters or designs 70 that appear on the outward-facing side surface of the material, will be easily visible to a person. Since the internal space 62 is a fluid-sealed chamber, the material 68 within the internal space will be protected from deterioration or discoloration resulting from moisture, dust, or other harmful substances present outside the chamber.

[0014] As described above, when the stopper 60 is installed at a fixed position within the central opening 54 of the annular outer body end wall 48, it fluid-tightly engages with the inner edge portion 52 of the annular outer body end wall, resulting in an internal space 62 that is a hollow fluid-tight chamber. To achieve this, the stopper 60 is preferably made of a soft, flexible, elastic silicone material that provides fluid tightness against glass.

[0015] In the illustrated embodiment, best shown in FIGS. 4, 11, and 19, the stopper 60 has a central portion 72 and an outer peripheral portion 74 that extends to its periphery. The outer peripheral portion 74 has an upper flange 76 that extends around the periphery of the central portion 72, and a lower flange 78 that is spaced below the upper flange and extends around the central portion. It defines a groove 80 that opens laterally outward between the two flanges, sized to firmly receive and grip the inner edge portion 52 of the annular outer body end wall 48 when the stopper is installed in the central opening 54 of the annular outer body end wall 48. Since the outer body side wall 28 and the annular outer body end wall 48 are preferably made of hard glass or another hard material, the stopper 60 must be quite bendable / flexible so that, as will be described in more detail below (see FIGS. 13 and 14), it can be easily installed by the user's hand into the central opening 54 of the annular outer body end wall. The upper and lower silicone flanges 76 and 78 grip the inner edge portion 52 of the annular outer body end wall 48 once installed, but if the stopper 60 is subjected to inward and outward forces during normal use, the degree of flexibility of the stopper can lead to the stopper accidentally moving out of the central opening 54 of the annular outer body end wall 48.

[0016] To address the flexibility issue, the central portion 72 of the stopper has a central cavity 82 that opens downward. The central cavity sidewall portion 84 extends around the periphery of the central cavity 82 and is laterally inside the upper and lower silicon flanges 76 and 78 and the groove 80 in the outer peripheral portion 74 of the stopper 60. The central cavity 82 has a central cavity upper end wall 86 and a downward central cavity opening end 88. The outer peripheral portion 74 further includes a groove 90 that communicates with the central cavity 82 and extends around the inner periphery of the outer peripheral portion of the stopper 60 and opens laterally inward. The groove 90 is present adjacent to the central cavity upper end wall 86 and extends laterally outward beyond the central cavity sidewall portion 84.

[0017] During normal use of the beverage container 10, once installed in the central opening 54 of the annular outer body end wall 48, the beverage container 10 further includes a substantially rigid and removably insertable reinforcing wall member or disk 92 with a central wall portion 94 and an outer peripheral edge portion 96 extending around it to provide rigidity to the stopper 60. When the disk 92 is positioned in the central cavity 82 adjacent to the central cavity upper end wall 86, it has a diameter / width slightly larger than the diameter / width of the central cavity sidewall portion 84 such that the peripheral edge portion 96 of the disk is positioned within the groove 90. The beverage container 10 is shown in FIGS. 5 and 6 in a pre-assembled state with the stopper 60 and the disk 92 separated from the body 12.

[0018] To install the disc 92 within the central cavity 82 of the stopper 60, the stopper is first installed within the central opening 54 of the annular outer body end wall 48. Then, the disc 92 is aligned with the central cavity 82 and pushed into the central cavity. The stopper 60 is sufficiently flexible and elastic, allowing the user to insert the disc 92 from the central cavity opening end 88 using manual pressure, and then move the disc axially along the central cavity side wall portion 84, with the outward lateral pressure applied by the disc compressing the central cavity side wall portion in the outward lateral direction. The disc 92 moves inward within the central cavity 82 to a fixed position adjacent to the central cavity upper end wall 86, with a peripheral portion 96 that aligns with the groove 90. When it reaches that position, the elasticity of the central cavity side wall portion 84 causes the central cavity side wall portion to move inward laterally, overlapping the peripheral edge portion 96 of the disc 92, and during normal use of the beverage container 10, the disc is securely held in place within the central cavity 82 with its peripheral edge portion in the groove 90, adjacent to the upper end wall 86 of the central cavity.

[0019] When fully inserted into the central cavity 82 of the stopper 60, the presence of the disc 92 provides the stopper 60 with additional rigidity, preventing it from moving accidentally during normal use, compared to the situation where a flexible stopper is not reinforced by the disc. However, the disc 92 can be removed when the user wishes to remove the stopper 60 from the central opening 54 of the annular outer body end wall 48, for example, to remove the sheet material 68 from the first internal space portion 64 of the internal space 62 for cleaning or replacement with a different sheet material.

[0020] The upper and lower silicone flanges 76 and 78 of the stopper 60, as well as the groove 80, tend to grip the annular outer body end wall 48 more securely than a typical smooth-walled plug that is pushed by hand into the central opening 54 of the annular outer body end wall, and as a result of using the rigid disc 92, the stopper 60 tends to be held more securely in place during use of the beverage container 10, but it should be noted that the stopper is detachable when the user wishes to remove it.

[0021] As described above, the central opening 54 of the annular outer body end wall 48 and the outer circumference of the stopper 60 are circular in shape, but may have other shapes to match. Similarly, although the central cavity 82 opening downwards in the central portion 72 of the disc 92 and the stopper 60 are described and illustrated as being circular in shape, they may have other shapes, including a central cavity side wall portion 84 and groove 90 extending around the periphery of the central cavity to receive the peripheral portion 96 of the disc in the groove 90. Furthermore, although the reinforcing wall member / disc 92 is described and illustrated as a flat disc, the reinforcing wall to be reinforced may be a thin cylindrical member, an annular member such as a ring, a C-clip, or a member of other shape that reinforces the stopper or, otherwise, can be positioned in the central cavity 82 of the central portion 72 of the stopper 60 to hold the stopper in place in the central opening 54 of the outer body end wall 48 during normal use of the container 10, and preferably to facilitate fluid sealing of the stopper with the outer body end wall.

[0022] To illustrate the use and assembly of the beverage container 10 more clearly, Figures 7 and 8 show the body 12 with a sheet-like material 68 intended to be positioned in a rolled shape within a first internal space portion 64 of the internal space 62 located below the lower end portion 16 of the body, with the stopper 60 removed from the central opening 54 of the annular outer body end wall 48. Figures 9 and 10 show the more tightly rolled sheet-like material 68 within a tube, with a diameter small enough to pass through the central opening 54 of the outer body 24 and a central tunnel 98 large enough to receive the lower end portion 36 of the inner body 22 inside. The tightly rolled sheet-like material 68 moves axially until it is completely within the first internal space portion 64, as shown in Figures 11 and 12, and is able to spread out sufficiently so that the outward-facing side surface 69 of the material is positioned close to, or very close to, the inside 28a of the outer body side wall 28.

[0023] Next, as shown in Figures 13 and 14, one side of the stopper 60 is oriented at an angle, and a portion of the inner edge portion 52 of the annular outer body end wall 48 is moved so that it is positioned between the upper flange 76 and the lower flange 78 of the outer circumference portion 74 of the stopper. As is most clearly seen in Figure 13, the stopper 60 is then bent and pushed axially with sufficient force so that the entire upper flange 76 is above the inner edge portion 52 of the annular outer body end wall 48, and the entire lower flange 78 remains below the inner edge portion, with the inner edge portion located within the groove 80 between the upper and lower flanges, as shown in Figures 15 and 16.

[0024] As also shown in Figures 15 and 16, the next step is to position the disc 92 below the central cavity 82 of the stopper 60, and then, as shown in Figures 17 and 18, one side of the disc is oriented at an angle and moved so that a portion of the peripheral portion 96 of the disc is positioned into the central cavity 82 of the stopper and into the groove 90 of the outer circumference 74 of the stopper. The disc 92 is then pushed upward in the axial direction with sufficient force so that the disc is completely inside the central cavity 82 and adjacent to the upper end wall 85 of the central cavity, with the peripheral portion 96 of the disc positioned in the groove 90, as shown in Figures 1-4.
