Receptacle with vent

A receptacle configured to receive a liner, comprising:

• a bottom wall;
• a first chamber section at least partially defined by the bottom wall and a side wall;
• a second chamber section superjacent the first chamber section and at least partially defined by the side wall and a rim;
• and
• a vent configured to reduce negative pressure in the first chamber section as the liner is filled and/or removed from the receptacle;
• wherein the second chamber section has a wider internal width than an internal width of the first chamber section,
• wherein the vent is formed by first, second, third, and fourth outward protrusions along an outer periphery of the side wall and each protrusion includes two side surfaces,
• wherein each outward protrusion has an internal width between the two side surfaces ranging from about 1 inch to about 3.5 inches and a depth ranging from about 0.25 inches to about 0.90 inches,
• wherein the side wall includes a first side wall portion between the first and second protrusions, a second side wall portion between the second and third protrusions, a third side wall portion between the third and fourth protrusions, and a fourth side wall portion between the fourth and first protrusions,
• wherein a distance along the first side wall portion between the first and second protrusions and a distance along the third side wall portion between the third and fourth protrusions are both greater than a distance along the second side wall portion between the second and third protrusions and a distance along the fourth side wall portion between the fourth and first protrusions, and
• wherein no other outward protrusions are formed along the first side wall portion between the first and second protrusions and along the third side wall portion between the third and fourth protrusions.

A method of using a receptacle with a liner, comprising:

• pulling the liner from a first chamber section of the receptacle that is configured to receive items, the first chamber section having a bottom wall and a first side wall with a vent;
• and
• pulling the liner from a second chamber section of the receptacle that is located above the first chamber section, wherein the second chamber section has a second side wall and an internal width that is wider than an internal width of the first chamber section;
• wherein the liner is pulled from the first chamber section such that the vent provides fluid communication between the second chamber section and a bottom area of the first chamber section,
• wherein the vent is formed by first, second, third, and fourth outward protrusions along an outer periphery of the first side wall and each protrusion includes two side surfaces, and
• wherein each outward protrusion has an internal width between the two side surfaces ranging from about 1 inch to about 3.5 inches and a depth of about 0.25 inches to about 0.90 inches,
• wherein the first side wall includes a first side wall portion between the first and second protrusions, a second side wall portion between the second and third protrusions, a third side wall portion between the third and fourth protrusions, and a fourth side wall portion between the fourth and first protrusions,
• wherein a distance along the first side wall portion between the first and second protrusions and a distance along the third side wall portion between the third and fourth protrusions are both greater than a distance along the second side wall portion between the second and third protrusions and a distance along the fourth side wall portion between the fourth and first protrusions, and
• wherein no other outward protrusions are formed along the first side wall portion between the first and second protrusions and along the third side wall portion between the third and fourth protrusions.
