Abstract A disposable apparatus for disposal of spittle is disclosed which includes a receptacle having a top and a base. A lid including a disk-shaped member having an aperture of selected diameter disposed therethrough is attached by a channel member which is adapted to expand outwardly to allow passage of a lip of a receptable into the channel to secure the lid to the receptacle. A hollow truncated conical section extends from the lid into the receptacle.

Claim 1
Independent Claim
343 words
A disposable apparatus for disposal of spittle, comprising: (a) a receptacle having a top and a base and a known distance between the top and the base, the receptacle being shaped in a truncated conical configuration slightly tapered inwardly from the top to the base and open at the top, the receptacle further including a lip disposed around the top having a known outer diameter; and (b) a lid comprising: (i) a generally disk-shaped member having an aperture of selected diameter disposed therethrough, the disk-shaped member having an outer diameter approximately equal to the outer diameter of the lip; (ii) a channel member connected transverse to the disk-shaped member around the perimeter of the disk-shaped member such that the channel member extends on one side of the disk-shaped member, the channel member being comprised of an elastic material and being shaped to form a mating recess to snuggly receive and mate with such a lip of such a receptacle when the lid is attached to the receptacle, the channel member being further adapted such that the channel member expands outwardly to allow passage of such a lip of a receptacle into the channel when the lid is being attached to the receptacle and substantially returns to shape once such a lip is in place in the channel to form a substantially fluid-tight seal; and (iii) a hollow truncated conical section having a first open end of inner diameter substantially equal to the diameter of the aperture of the disk-shaped member and a second open end of inner diameter less than the diameter of the first open end, whereby the conical section has a tapered bore extending therethrough, the first open end of the conical section being secured to the disk-shaped member such that the bore aligned with the aperture and such that the conical section extends transversely from the disk-shaped member on the same side of the disk-shaped member as the channel member, the conical section further having a length of one-half to three-fourths of the distance from the top to the base.

Claim 6
Dependent Claim
295 words
A lid for a receptacle such as a paper or plastic cup having a top and a base, the receptacle being open at the top and having an outwardly extending lip of known outer diameter disposed around the top, the lid comprising: (a) a generally disk-shaped member having an aperture of selected diameter disposed therethrough; the disk-shaped member having an outer diameter approximately equal to the outer diameter of the lip; (b) a channel member connected transverse to the disk-shaped member around the perimeter of the disk-shaped member such that the channel member extends on one side of the disk-shaped member, the channel member being comprised of an elastic material and being shaped to form a mating recess to snuggly receive and mate with such a lip of such a receptacle when the lid is attached to the receptacle, the channel member being further adapted such that the channel member expands outwardly to allow passage of such a lip of a receptacle into the channel when the lid is being attached to the receptacle and substantially returns to shape once such a lip is in place in the channel to form a substantially fluid-tight seal; and (c) a hollow truncated conical section having a first open end of inner diameter substantially equal to the diameter of the aperture of the disk-shaped member and a second open end of inner diameter less than the diameter of the first open end, whereby the conical section has a tapered bore extending therethrough, the first open end of the conical section being secured to the disk-shaped member such that the bore aligns with the aperture and such that the conical section extends transversely from the disk-shaped member on the same side of the disk-shaped member as the channel member.
Claim 7
Dependent Claim
295 words
A lid for a receptacle such as a paper or plastic cup having a top and a base, the receptacle being open at the top and having an outwardly extending lip of known outer diameter disposed around the top, the lid comprising: (a) a generally disk-shaped member having an aperture of selected diameter disposed therethrough; the disk-shaped member having an outer diameter approximately equal to the outer diameter of the lip; (b) a channel member connected transverse to the disk-shaped member around the perimeter of the disk-shaped member such that the channel member extends on one side of the disk-shaped member, the channel member being comprised of an elastic material and being shaped to form a mating recess to snuggly receive and mate with such a lip of such a receptacle when the lid is attached to the receptacle, the channel member being further adapted such that the channel member expands outwardly to allow passage of such a lip of a receptacle into the channel when the lid is being attached to the receptacle and substantially returns to shape once such a lip is in place in the channel to form a substantially fluid-tight seal; and (c) a hollow truncated conical section having a first open end of inner diameter substantially equal to the diameter of the aperture of the disk-shaped member and a second open end of inner diameter less than the diameter of the first open end, whereby the conical section has a tapered bore extending therethrough, the first open end of the conical section being secured to the disk-shaped member such that the bore aligns with the aperture and such that the conical section extends transversely from the disk-shaped member on the same side of the disk-shaped member as the channel member.
Claim 8
Dependent Claim
