Abstract
Abstract A base-cup for supporting a bottle in an upright position is disclosed for use with a bottle having a semi-hemispherical bottom and having a radial indentation in the lower portion of its otherwise generally cylindrical body. The base-cup includes a sole plate and a cylindrical side wall having an open top edge with an annular bead on the inside thereof, and a bottom edge smoothly merging into the sole plate. The base-cup also includes limit means projecting upward from the sole plate into the interior of the base-cup for preventing the over-insertion of the bottle into the base-cup. Preferred embodiments of the limit means are illustrated which include circumferentially equally spaced and radially extending fillet webs joining the side wall to the sole plate, and upwardly projecting rings situated approximately midway between the center of the sole plate and the point at which the side wall smoothly merges into the sole plate.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
115 words
A base-cup for supporting a bottle in an upright position, the bottle having a semi-hemispherical bottom and having a radial indentation in a lower portion of its otherwise generally cylindrical body, the base-cup comprising: (a) a sole plate, (b) a cylindrical side wall having an open top edge and a bottom edge smoothly merging into the sole plate, (c) an annular bead on the inside of the top edge for engaging the radial indentation of the bottle body, and (d) limit means for preventing the over-insertion of the bottle into the base-cup, the limit means comprising at least three circumferentially equally spaced and radially extending fillet webs joined to the side wall of the base-cup.
Claim 2
Dependent Claim
115 words
A base-cup for supporting a bottle in an upright position, the bottle having a semi-hemispherical bottom and having a radial indentation in a lower portion of its otherwise generally cylindrical body, the base-cup comprising: (a) a sole plate, (b) a cylindrical side wall having an open top edge and a bottom edge smoothly merging into the sole plate, (c) an annular bead on the inside of the top edge for engaging the radial indentation of the bottle body, and (d) limit means for preventing the over-insertion of the bottle into the base-cup, the limit means comprising at least three circumferentially equally spaced and radially extending fillet webs joined to the side wall of the base-cup.
Claim 3
Dependent Claim
13 words
The base-cup of claim 1 wherein each of said fillet webs is solid.
Claim 4
Dependent Claim
39 words
The base-cup of claim 1 wherein each of said fillet webs is hollow, there being a hollow present in a lower portion of the side wall and an outer portion of the sole plate corresponding to each fillet web.
Claim 5
Dependent Claim
17 words
The base-cup of claim 1 wherein the interior surface of each of said fillet webs is concave.
Claim 6
Dependent Claim
148 words
A base-cup for supporting a bottle in an upright position, the bottle having a semi-hemispherical bottom and having a radial indentation in a lower portion of its otherwise generally cylindrical body, the base-cup comprising: (a) a sole plate, (b) a cylindrical side wall having an open top edge and a bottom edge smoothly merging into the sole plate, (c) an annular bead on the inside of the top edge for engaging the radial indentation on the bottle body, and (d) limit means projecting upward from the sole plate into the interior of the base cup for preventing the over-insertion of the bottle into the base-cup, the limit means being normally downwardly spaced from the bottle bottom yet in sufficient proximity to contact the bottle bottom if the bottle is inserted significantly beyond the point of engagement of said annular bead and said radial indentation on the bottle bottom.
Claim 7
Dependent Claim
148 words
A base-cup for supporting a bottle in an upright position, the bottle having a semi-hemispherical bottom and having a radial indentation in a lower portion of its otherwise generally cylindrical body, the base-cup comprising: (a) a sole plate, (b) a cylindrical side wall having an open top edge and a bottom edge smoothly merging into the sole plate, (c) an annular bead on the inside of the top edge for engaging the radial indentation on the bottle body, and (d) limit means projecting upward from the sole plate into the interior of the base cup for preventing the over-insertion of the bottle into the base-cup, the limit means being normally downwardly spaced from the bottle bottom yet in sufficient proximity to contact the bottle bottom if the bottle is inserted significantly beyond the point of engagement of said annular bead and said radial indentation on the bottle bottom.
Claim 8
Dependent Claim
27 words
The base-cup of claim 5 wherein the limit means comprises a ring situated approximately half way between the center of the sole plate and the cylindrical sidewall.
Claim 9
Dependent Claim
27 words
The base-cup of claim 6 wherein the ring is hollow, there being a hollow present in the lower surface of the sole plate corresponding to the ring.
Claim 10
Dependent Claim
52 words
The base-cup of claim 6 wherein the sole plate periphery is flexible whereby the ring can be displaced upwardly and downwardly with respect to the open top edge of the side wall, the displacement causing respectively a corresponding proportional upward and inward, and downward and outward, displacement of the sole plate periphery.
Claim 11
Dependent Claim
150 words
A base-cup for supporting a bottle in an upright position, the bottle having a semi-hemispherical bottom and having a radial indentation in a lower portion of its otherwise generally cylindrical body, the base-cup comprising: (a) a sole plate; (b) a cylindrical side wall having an open top edge and a flexible bottom edge smoothly merging into the sole plate, (c) an annular bead on the inside of the top edge for engaging the radial indentation on the bottle body, and (d) a ring situated approximately half way between the center of the sole plate and the cylindrical sidewall, and projecting upward from the sole plate into the interior of the base-cup a distance insufficient to normally contact the bottle bottom yet sufficient to contact the bottle bottom if the bottle is inserted significantly beyond the point of engagement of said annular bead and said radial indentation of the bottle body.
Claim 12
Dependent Claim
150 words
A base-cup for supporting a bottle in an upright position, the bottle having a semi-hemispherical bottom and having a radial indentation in a lower portion of its otherwise generally cylindrical body, the base-cup comprising: (a) a sole plate; (b) a cylindrical side wall having an open top edge and a flexible bottom edge smoothly merging into the sole plate, (c) an annular bead on the inside of the top edge for engaging the radial indentation on the bottle body, and (d) a ring situated approximately half way between the center of the sole plate and the cylindrical sidewall, and projecting upward from the sole plate into the interior of the base-cup a distance insufficient to normally contact the bottle bottom yet sufficient to contact the bottle bottom if the bottle is inserted significantly beyond the point of engagement of said annular bead and said radial indentation of the bottle body.
Claim 13
Independent Claim
215 words
A method of ensuring stable vertical alignment of the bottle having a semi-hemispherical bottom comprising the steps of: (a) providing a bottle having a semi-hemispherical bottom with a radial indentation in a lower portion of the otherwise generally cylindrical body of the bottle; (b) providing a base-cup for supporting the bottle with a sole plate, a cylindrical side wall having an open top edge and a bottom edge smoothly merging into the sole plate, an annular bead on the inside of the top edge for engaging the radial indentation of the bottle body, and limit means projecting upward from the sole plate into the interior of the base-cup for preventing the over insertion of the bottle into the base-cup; (c) axially aligning the open top of the base-cup with the semi-hemispherical bottom of the bottle; (d) telescopically moving the base-cup and bottle together along a common axis until the annular bead of the base-cup is received in the radial indentation of the bottle body, the limit means preventing the insertion of the bottle into the base-cup significantly beyond the point of bead-indentation engagement; and (e) releasing any axial pressure on the base-cup and bottle combination due to the relative telescopic movement therebetween whereby the limit means assumes a position downwardly spaced from the bottle bottom.
