Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
102 words
A cheese mold of plastics material comprising: at least two matching shells each having an integral bottom member, said two shells and the bottom members when coupled together forming a hollow mold having a substantially constant integral cross-section along its length and with a bottom closure, said shells having a moisture permeably layer securely attached to their inner walls, said mold having at least one outlet opening for removing whey; said bottom members having a hinged connection therebetween and having adjacent thereto an annular recess and a hollow follower container member having edges frictionally engaged with said mold in said annular recess.
Claim 2
Dependent Claim
102 words
A cheese mold of plastics material comprising: at least two matching shells each having an integral bottom member, said two shells and the bottom members when coupled together forming a hollow mold having a substantially constant integral cross-section along its length and with a bottom closure, said shells having a moisture permeably layer securely attached to their inner walls, said mold having at least one outlet opening for removing whey; said bottom members having a hinged connection therebetween and having adjacent thereto an annular recess and a hollow follower container member having edges frictionally engaged with said mold in said annular recess.
Claim 3
Dependent Claim
23 words
Plastic cheese mold as claimed in claim 1, wherein the plastic shell parts are half-cylindrical shells being provided with half-cylindrical bottom end walls.
Claim 4
Dependent Claim
56 words
Plastic cheese mold as claimed in claim 1, wherein an end edge of a plastic shell part is provided with a groove whereas the opposite end edge of an other shell part is provided with a rib in such a manner that a dovetail connection is formed at an interaction of a rib and a groove.
Claim 5
Dependent Claim
24 words
Plastic cheese mold as claimed in claim 1, wherein the fixing means are clamping sledges (6) engaging protruding rib-shaped portions of the shell parts.
Claim 6
Dependent Claim
17 words
Plastic cheese mold as claimed in claim 1, wherein the shell parts consist of a thermoplastic material.
Claim 7
Dependent Claim
87 words
A plastic cheese mold as claimed in claim 1, wherein the inner edges of clamping sledges (6) and the outer edges of the protruding ribs on shell parts are diverging to the bottom side of the mold so that on moving the clamping sledges toward the direction of the open end of the molds, the shell parts and the bottom end walls are sealingly interconnected while a displacement of the clamping sledges toward the bottom side of the mold moves the shell parts apart from each other.
Claim 8
Dependent Claim
16 words
Plastic cheese mold as claimed in claim 1, wherein the two shell parts are pivotably interconnected.
Claim 9
Dependent Claim
