Various embodiments concern a handheld beverage container. The beverage container includes a vacuum chamber located radially between an inner tubular sidewall and an outer tubular sidewall and axially between an inner bottom wall and an outer bottom wall. The combined heat capacity of both of the inner tubular sidewall and the inner bottom wall can be greater than the combined heat capacity of both of the outer tubular sidewall and the outer bottom wall such that a vacuum insulated thermal reserve is formed. Heat can be exchanged between the thermal reserve and the beverage to stabilize the temperature of the beverage to counteract ambient cooling/heating of the beverage. Various embodiments concern a cap that seals with a disposable cup that is held within a container body, allowing a beverage to be contained in the disposable cup while being insulated by the container body, with or without a thermal reserve.

Gaskets and beverage container systems and kits comprising gaskets. An exemplary gasket of a beverage container insulating system disclosed herein includes a gasket body comprising a generally cylindrical shape, a gasket opening, and an inner wall that faces a central axis of the gasket body, at least one set of protrusions positioned on the inner wall and extending radially inward toward the central axis of the gasket body, the first set of protrusions defining at least one pressure-alleviating gap.

An insulating holder is provided for a conventional disposable beverage cup. The insulating holder includes an upward-facing flange that supports the beverage cup at its peripheral bead and without interfering with a disposable lid that may be fitted to the cup by snap fit over the peripheral bead. The insulating holder further includes a retaining mechanism that holds the disposable cup and lid in the holder without interfering with the ability of the user to drink from the cup. The insulating holder further includes means to facilitate insertion of the cup into the holder without requiring the user to hold the cup either by its bead or by the lid.

An assembly for holding a beverage cup is provided herein. The assembly may include a cup holder and a retainer. The cup holder may include a closed bottom, a generally cylindrical or frustoconical side wall, and an upper access opening configured to receive the beverage cup. An outer surface of the side wall of the cup holder may include a latch-engagement feature. The retainer may include a retaining ring, a skirt, a latch, and a hinge. The latch is configured to engage the latch-engagement feature.

Gaskets and beverage container systems and kits comprising gaskets. An exemplary gasket disclosed herein includes a gasket body comprising a generally cylindrical shape, at least two arcuate flanges positioned within a relative inside of the gasket body, the at least two arcuate flanges extending inward from the gasket body, and at least one gap existing between two arcuate flanges of the at least two arcuate flanges.

A device 200 is disclosed for holding a beverage container 216 having any size within a range of sizes. The holder 200 has a side wall 202 defining an opening 208 through which the beverage container is insertable and a base 204. A collar 210 is positioned within the opening 208, and the side wall 202 and the base 204 together define a cavity 214 for receiving the beverage container 216. The collar 210 is pliable and is arranged to deform to contact and grip the beverage container 216. The opening 208 has a first width and the collar 210 has an aperture 212 formed therein, the aperture 212 having a second width, the first and second widths being selected to adapt the device to the desired range of sizes.

Apparatuses and devices for preventing heat transfer through fluids contained in a fluid container are disclosed. The device comprises an insulation sleeve having at least one wall and a gripping ring having an inner surface configured to grip the fluid container and an outer surface configured to couple with an inner surface of the insulation sleeve. The insulation sleeve includes a first coupling mechanism and the gripping ring includes a second coupling mechanism. The first coupling mechanism and the second coupling mechanism are configured to couple with each other to snugly fit the insulation sleeve and the gripping ring over the fluid container.
