Insert assembly for changing temperature of quantity of liquid contained in bottle

An insert assembly for use in cooling the temperature of a quantity of liquid contained in a bottle, said insert assembly comprising:

• (a) an end cap securable to a top of the bottle;
• (b) an elongated hollow insert member filled with a quantity of freezable material, said insert attached to and extending downwardly from said end cap into the bottle and into the quantity liquid therein for cooling the quantity of liquid when said end cap is secured to the bottle;
• (c) means defined on said end cap for securing said end cap to the top of the bottle, said securing means being adapted to allow said end cap and insert member therewith to be removed from the bottle and placed in a freezer for freezing said quantity of liquid within said insert member and then re-secured on the bottle at a later time;
• and
• (d) an elongate protective cover adapted to removably fit over said hollow insert member and releasably attach to said end cap only when said end cap and insert member are removed from the bottle, said cover and end cap together enclosing said insert member so as to to maintain said insert member in a sanitary state when said end cap and insert member are not secured on the bottle.

A method of cooling a quantity of liquid contained within a bottle, said method comprising the steps of:

• (a) providing an end cap which may be removeably secured on a bottle containing a liquid to be cooled;
• (b) providing an elongated hollow insert member connected to the end cap so as to extend downward from said end cap and is filled with a quantity of freezable liquid;
• (c) providing a protective cover fittable over said insert member and releasably securable to said end cap such that together said cover and end cap enclose said insert member to protect said insert member from damage and maintain said insert member in a sanitary state, said connected cover, insert member and end cap thereby providing an insert assembly;
• (d) placing said insert assembly in a freezer at least until said quantity of liquid within said insert member is substantially frozen;
• (e) removing said insert assembly from the freezer;
• (f) removing said cover from said insert member and end cap;
• and
• (g) securing said end cap on the bottle so that said insert member extends downward into the bottle and into the quantity of liquid contained within the bottle thereby allowing for the transfer of heat from the quantity of liquid in the bottle to said quantity of frozen liquid within said insert member.

A method of cooling an insert assembly and maintaining said insert assembly in a sanitary state ready for use in cooling a quantity of liquid contained within a bottle, said cooling method comprising the steps of:

• (a) providing an end cap which may be removeably secured on a bottle containing a liquid to be cooled;
• (b) providing an elongated hollow insert member connected to the end cap so as to extend downward from said end cap and is filled with a quantity of freezable liquid;
• (c) providing a protective cover for enclosing said insert member and end cap so as to protect said insert member from damage and maintain said insert member in a sanitary state, said protective cover and said insert member and end cap enclosed therein thereby providing an insert assembly;
• and
• (d) placing said insert assembly in a freezer at least until said quantity of liquid within said insert member is substantially frozen.
