Abstract
Abstract Apparatus and method for changing and setting a peeled, warm or hot hard-boiled egg into a desired shape, for example a cubic shape. This apparatus comprises a tubular chamber having a required inner cross sectional shape and having a threaded neck portion, a bottom plate for closing one end of the chamber, a pressing member for progressively pressing the boiled egg contained in the chamber, and a threaded cap for progressively threadably pressing the pressing member. By putting an unshelled hot egg soon after being boiled, then inserting the pressing member through an open inlet of the neck of the chamber and progressively pressing this egg thereby, and keeping this pressed state of the egg for some time while leaving it to be cooled, it is possible to obtain a boiled egg which has been changed into a shape defined by the chamber and the pressing member. Also, by the use of a bottom plate having indentation formed on its egg-contacting surface, and after the processed egg is taken out, by cutting away those portions of the egg which have filled in the indentation when the egg was pressed, the surface of the boiled egg is imparted with the pattern of the indentation.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
112 words
An apparatus for deforming a boiled egg, comprising: a chamber defining a tubular space of a desired configuration; means positioned to close one end of said tubular space; smoothly inclined portion extending continuously from the top edges of the other end of said tubular space and having a progressively enlarged cross section as it goes farther from the top edges of said tubular space, said cross section of the inclined portion being larger than the cross section of the tubular space; a pressing member having a pressing surface with a shape substantially identical with the cross section of said tubular space; and means operable to move said pressing member within said chamber.
Claim 2
Independent Claim
112 words
An apparatus for deforming a boiled egg, comprising: a chamber defining a tubular space of a desired configuration; means positioned to close one end of said tubular space; smoothly inclined portion extending continuously from the top edges of the other end of said tubular space and having a progressively enlarged cross section as it goes farther from the top edges of said tubular space, said cross section of the inclined portion being larger than the cross section of the tubular space; a pressing member having a pressing surface with a shape substantially identical with the cross section of said tubular space; and means operable to move said pressing member within said chamber.
Claim 3
Dependent Claim
16 words
An apparatus according to claim 1, in which: said tubular space has a square cross section.
Claim 4
Dependent Claim
24 words
An apparatus according to claim 2, in which: each side of said square cross section is between 3 cm and 5 cm in length.
Claim 5
Dependent Claim
62 words
An apparatus according to claim 1, further comprising: a cylindrical neck portion having a threaded groove and coupled to one end of said chamber, and in which; said means of moving the pressing member is constructed of a cap having a threaded groove, and said threaded groove formed on said cylindrical neck portion for engagement with said threaded groove of said cap.
Claim 6
Dependent Claim
38 words
An apparatus according to claim 1, in which: said means for moving the pressing member is constructed of a cap having a tooth, and a tooth formed on said chamber for engagement with said tooth of the cap.
Claim 7
Dependent Claim
35 words
An apparatus according to claim 1, in which: said means for closing one end of said tubular space is constructed of a removable bottom plate applied to the bottom of said chamber in this chamber.
Claim 8
Dependent Claim
53 words
An apparatus according to claim 6, in which: said bottom plate is of a dimension defining, between this bottom plate and a side wall of said chamber, a gap which allows the passage therethrough of air and moisture but does not allow the passage of a portion of the boiled egg itself therethrough.
Claim 9
Dependent Claim
21 words
An apparatus according to claim 6, in which: said bottom plate has a recessed groove pattern formed on one surface thereof.
Claim 10
Independent Claim
177 words
An apparatus for deforming a boiled egg, comprising: a main body consisting of a chamber defining a square tubular space therein and having an open top end and an open bottom end and a tubular portion coupled to said open top end through a smoothly inclined portion extending continuously from the edges of said open top end of said tubular space and having a progressively enlarged cross section as it goes farther from the top edges of said tubular space, said cross section of the inclined portion being larger than the cross section of the tubular space; means positioned to close said open bottom end of said chamber; a gap defined between said closing means and the inner side walls of said chamber for the passage of air and moisture therethrough; a pressing member having a pressing surface with a shape substantially identical with the cross section of said tubular space; and a cap having a threaded groove engaging in the threaded groove provided on said tubular portion and having a portion for pressing-on said pressing member.
Claim 11
Independent Claim
177 words
An apparatus for deforming a boiled egg, comprising: a main body consisting of a chamber defining a square tubular space therein and having an open top end and an open bottom end and a tubular portion coupled to said open top end through a smoothly inclined portion extending continuously from the edges of said open top end of said tubular space and having a progressively enlarged cross section as it goes farther from the top edges of said tubular space, said cross section of the inclined portion being larger than the cross section of the tubular space; means positioned to close said open bottom end of said chamber; a gap defined between said closing means and the inner side walls of said chamber for the passage of air and moisture therethrough; a pressing member having a pressing surface with a shape substantially identical with the cross section of said tubular space; and a cap having a threaded groove engaging in the threaded groove provided on said tubular portion and having a portion for pressing-on said pressing member.
Claim 12
Dependent Claim
35 words
An apparatus according to claim 9, in which: said means for closing said opening provided on the other end of the chamber is constructed of a bottom plate having a pattern of a recessed groove.
