Abstract
Abstract A balloon filler than includes a two piece evacuation housing arranged to receive a balloon attachment unit that holds a balloon in where the balloon end projects into the evacuation housing and receives a spreader tube whose insertion into the balloon unit attachment opens the balloon mouth and provides a seal between the exterior neck of the balloon and a shoulder of the balloon attachment unit base, a motor and blower are provided to create a sub-atmospheric pressure in the evacuation housing and an object holding tube receiving a balloon on one end and is telescoped onto a pressure tube connected at its opposite end to a pressure chamber receiving pressurized air from the blower.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
122 words
A balloon filler comprising, an evacuation housing consisting of upper and lower sections, for releasable coupling in sealing engagement along common edges at a middle of said evacuation housing and having a combined internal volume for accommodating a filled balloon; means for providing full access to the interior of said evacuation housing; means to hold a balloon in position where the balloons end thereof projects into the interior of said evacuation housing through an opening in said evacuation housing; means to both open the mouth of a balloon secured to the means to hold the balloon and to seal the opening in the said evacuation housing around the open balloon neck; and means to provide a sub-atmospheric pressure in the evacuation housing.
Claim 2
Dependent Claim
122 words
A balloon filler comprising, an evacuation housing consisting of upper and lower sections, for releasable coupling in sealing engagement along common edges at a middle of said evacuation housing and having a combined internal volume for accommodating a filled balloon; means for providing full access to the interior of said evacuation housing; means to hold a balloon in position where the balloons end thereof projects into the interior of said evacuation housing through an opening in said evacuation housing; means to both open the mouth of a balloon secured to the means to hold the balloon and to seal the opening in the said evacuation housing around the open balloon neck; and means to provide a sub-atmospheric pressure in the evacuation housing.
Claim 3
Dependent Claim
47 words
A balloon filler as in claim 1, wherein the evacuation housing upper and lower sections are each formed as a truncated cone, the base of each having a greatest diameter, the lower housing section rotated to receive in sealing engagement the base of said upper housing section.
Claim 4
Dependent Claim
21 words
A balloon filler as in claim 2, further including handle means fixed to the upper housing section, adjacent the base thereof.
Claim 5
Dependent Claim
113 words
A balloon filler as in claim 3, wherein the upper housing section includes a sleeve defining an opening through the truncated end thereof and into the upper housing; and the means to hold a balloon in position where the balloons end projects into the interior of the evacuation housing comprises a balloon attachment unit with a cylindrical body for telescoping into said opening through the truncated end of the upper housing, a diaphragm in the cylindrical body where around a plurality of flexible flaps are pivotally connected to extend into the cylindrical body, and said flexible flaps include outwardly projecting hook means on the ends thereof to receive the mouth of a balloon.
Claim 6
Dependent Claim
86 words
A balloon filler as in claim 4, wherein the means to open the mouth of a balloon comprises a spreader tube for telescoping into the balloon attachment unit so as to spread the flexible flaps, thereby opening the mouth of a balloon mounted to the hooks on the flexible flap ends and to move the neck of the balloon into sealing engagement with a shoulder at a base of said balloon attachment unit that defines an opening through the truncated end and into the upper housing.
Claim 7
Dependent Claim
115 words
A balloon filler as in claim 5, wherein the means to provide a sub-atmospheric pressure in the evacuation housing comprises, means defining an opening through the truncated end of the lower evacuation housing; and a motor housing fixed to the truncated end of the lower housing and having a motor therein containing a blower driven by motor for pulling air from the evacuation housing through the opening formed through said truncated end of said lower evacuation housing, a pressure chamber receiving pressurized air from said blower, a discharge outlet through said motor housing and a check valve in said discharge outlet arranged to open when a predetermined air pressure is achieved in said pressure chamber.
Claim 8
Dependent Claim
61 words
A balloon filler as in claim 6, further including a standpipe having one end connected to the discharge outlet and a screen cover over the other end; and an article holding tube having one end telescoped over the end of the standpipe wherever said screen is positioned, and a flared opposite end arranged to receive the mouth of a balloon thereover.
Claim 9
Dependent Claim
84 words
A balloon filler as in claim 2, wherein the means to open the mouth of a balloon comprises a spreader tube for telescoping into a balloon attachment unit so as to spread flexible flaps thereof opening the mouth of a balloon attached over hook means on the flexible flaps and to move the neck of the balloon into sealing engagement with a shoulder at the base of said balloon attachment unit that defines an opening through the truncated end and into the upper housing.
Claim 10
Dependent Claim
119 words
A balloon filler as in claim 2, wherein the means to provide a sub-atmospheric pressure in the evacuation housing comprises means defining an opening through the truncated end of the lower evacuation housing; and a motor housing fixed to the truncated end of said lower evacuation housing and having a motor therein and a blower driven by said motor for pulling air from the evacuation housing through the truncated end of said lower evacuation housing, a pressure chamber receiving pressurized air from said blower, a discharge outlet through said motor housing from said discharge outlet, and a check valve in said discharge outlet that is arranged to open when a predetermined air pressure is present in the pressure chamber.
