Abstract
Abstract A blow dart game comprises a tube having an abutment therein for abutting against a dart which is inserted into the tube, thereby preventing the dart from coming out of the tube and being ingested or swallowed by a user. The abutment may be provided directly on the tube, or on a mouthpiece which is connected to the tube at one end of the tube. The darts have suction cups at the front ends thereof and a seal for providing a substantial air seal against the inner surface of the tube. The dart further has a shock absorbing section at the forward portion thereof to enhance its adherence to non-flat and/or non-perpendicular target surfaces. An impact member is provided in some of the darts to improve adherence to the target surface.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
209 words
A blow dart game comprising: an elongated hollow tubular member which is open at both ends; abutment means spaced inwardly from an end of said elongated tubular member and comprising an abutment internally of said elongated tubular member; a dart having a front target impacting suction cup member, an air guiding section extending rearwardly of said target impacting member, and a resiliently yieldable shock-absorbing portion extending rearwardly of said target impacting member, said shock absorbing portion comprising at least two resilient, spaced apart members coupling said front target impacting member with said air guiding section of said dart; and sealing means on said dart for providing a substantial seal interior of said elongated tubular member when said dart is placed interior of said elongated tubular member, said sealing means being rearward of said target impacting suction cup member, said suction cup member being smaller in diameter than said sealing means so that said suction cup member passes substantially freely through said tubular member; said abutment means being abuttable against at least a portion of said dart when said dart is interior of said elongated tubular member to prevent said dart from inadvertently coming out of the end of said elongated tubular member at which said abutment means is located.
