Balloon garland assembly and balloon assemblies therefor

A balloon assembly comprising:

• a balloon having a body and a neck terminating in a lip;
• a port having only a single inlet for passage of gas into the body of the balloon;
• a valve assembly comprising an upper valve body and a separate lower valve body cooperating to define an interior bound between the upper and lower valve bodies;
• a valve member disposed in the interior which moves from a first position to a second position in response to the passage of air through the valve assembly from the single inlet of the port to the balloon;
• in the first position, the valve member is against the lower valve body, disabling the passage of air through the valve assembly from the balloon to the port;
• and
• in the second position, the valve member is away from the lower valve body, enabling the passage of air through the valve assembly from the single inlet to the balloon;
• wherein the port comprises:
• an inner sidewall and an outer sidewall spaced apart by a flange extending radially outward from the inner sidewall to the outer sidewall proximate a lower end of the outer sidewall;
• the inner sidewall has a lower end with a barb, an opposed upper end with a frustum, and an open central channel extending entirely through the inner sidewall from the lower to the upper end;
• and
• the outer sidewall has a lower end with a sloped lower surface, an opposed upper end defining an upper rim of the port, wherein the upper rim has a lip directed radially inward, and a socket in communication with the central channel.

A balloon assembly comprising:

• a balloon having a body and a neck terminating in a lip;
• a port, the port comprising:
• an inner sidewall and an outer sidewall spaced apart by a flange extending radially outward from the inner sidewall to the outer sidewall;
• the inner sidewall has a lower end, an opposed upper end with a frustum, and an open central channel extending entirely through the inner sidewall from the lower to the upper end;
• and
• the outer sidewall has a lower end, an opposed upper end defining an upper rim of the port, and a socket in communication with the central channel;
• and
• a valve assembly received in the socket of the port, the valve assembly comprising:
• a lower valve body comprising a sidewall extending from upper and lower ends, and having an inner flange defining an annular seat bounding a valve aperture within the lower valve body;
• an upper valve body comprising a lower collar, an upper cone projecting radially outward away from the lower collar, and a slotted cup therebetween;
• and
• a disc disposed between the upper and lower valve bodies for movement from a first position to a second position in response to passage of air through the valve assembly from the port to the balloon.
