Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
128 words
A method of forming a single piece drinking receptacle of a flowable and hardenable material having a rim and a bottom and a wall extending from said bottom to said rim comprising the steps of forming a lip of the material of said wall having a lip surface facing said rim and extending from said wall inwardly of said receptacle between said rim and said bottom, forming a guard of said lip and wall material extending from said lip surface toward said rim spaced from and generally parallel to said wall surface and having spaced portions thereof defining with said lip surface openings adjacent said lip surface, and subsequently moving said guard into a second position in which said guard extends inwardly of said receptacLe past said lip.
Claim 2
Independent Claim
128 words
A method of forming a single piece drinking receptacle of a flowable and hardenable material having a rim and a bottom and a wall extending from said bottom to said rim comprising the steps of forming a lip of the material of said wall having a lip surface facing said rim and extending from said wall inwardly of said receptacle between said rim and said bottom, forming a guard of said lip and wall material extending from said lip surface toward said rim spaced from and generally parallel to said wall surface and having spaced portions thereof defining with said lip surface openings adjacent said lip surface, and subsequently moving said guard into a second position in which said guard extends inwardly of said receptacLe past said lip.
Claim 3
Dependent Claim
130 words
The method of claim 1 wherein said forming steps include the steps of forming a parison, the parison being hollow and having an open end and a closed end, placing said parison in a first mold part, said first mold part having an open end and a closed end, said closed parison end being positioned adjacent to said closed mold end and said open mold end being positioned adjacent to said open parison end, inserting a second mold part having portions which are complements of said lip and guard into said parison through said open parison end, said parison having a sufficient volume of said material to fill the space between said first and second mold parts including said complemental portions, and filling said complemental portions and said mold space.
Claim 4
Dependent Claim
82 words
The method of claim 2 wherein said inserting step includes the step of inserting a plunger having a lip formed in its exterior surface separating a larger plunger portion adjacent a rim-forming portion and a smaller plunger portion adjacent a bottom-forming portion and a plurality of spaced cavities in said larger portion with openings arranged on said lip to be spaced apart and spaced from the exterior surface of said larger portion, and said filling step includes the filling of said cavities.
Claim 5
Dependent Claim
65 words
The method of claim 3 wherein said cavities are elongated and extend generally axially of said plunger, said openings being spaced and extending around said small portion, said first mold part having an interior surface, said interior surface being complementary to the exterior surface of a drinking receptacle, said exterior surface of said second mold part being complementary to the interior surface of said receptacle.
Claim 6
Dependent Claim
92 words
The method of claim 2 wherein said moving step includes the steps of breaking said first and second mold parts apart, removing said second mold part from within said molded part without removing the molded part from said first mold part, inserting a third mold part into the molded part previously formed by said first and second mold parts, engaging said guard with said third mold part, and moving said guard so as to extend inwardly of said receptacle past said lip while maintaining the shape of the remainder of said receptacle.
Claim 7
Dependent Claim
108 words
The method of claim 2 wherein said moving steps include the step of breaking said first and second mold parts apart, spacing said second mold part from said first mold part without removing the molded part from said first mold part, rotating said second mold part to misalign said guard with its complemental portions of said second mold part engaging said guard with said second mold part portions which are complemental to said lip, and moving said guard so as to extend inwardly of said receptacle past said lip by partially closing said first and second mold parts while maintaining the shape of the remainder of said receptacle.
