Abstract
Abstract A method for producing frozen confections of re-entrant shape using moulds made of flexible, elastic material, comprising filling moulds made of said material with confection mix, inserting a handle into the mix, contacting the outside of the filled mould with a freezant so as to freeze the mix and anchor the handle, and withdrawing the handle, whereby the mould distorts and expands to release the frozen product. Distortion of the shape of the mould due to the pressure of liquid freezant is avoided by filling the mould with confection mix prior to its immersion in the freezant, partially immersing it until the exterior of the liquid mix has frozen, and then equalizing the levels of the mix and the freezant.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
114 words
A method of forming moulded ice confections of re-entrant shape comprising filling ice confection mix into a plurality of thin-wall flexible elastic moulds of cavity shape which is re-entrant along at least one wall surface from the deepest part of the mould to the mouth of the mould, inserting a handle into the ice confection mix in each mould, applying a liquid freezant to the outer surface of each mould so as to freeze the ice confection mix and anchor the handle while said thin-wall moulds are supported by said freezant, and withdrawing the handle so as to cause the moulds to distort and release an ice confection of re-entrant shape on the handle.
Claim 2
Independent Claim
114 words
A method of forming moulded ice confections of re-entrant shape comprising filling ice confection mix into a plurality of thin-wall flexible elastic moulds of cavity shape which is re-entrant along at least one wall surface from the deepest part of the mould to the mouth of the mould, inserting a handle into the ice confection mix in each mould, applying a liquid freezant to the outer surface of each mould so as to freeze the ice confection mix and anchor the handle while said thin-wall moulds are supported by said freezant, and withdrawing the handle so as to cause the moulds to distort and release an ice confection of re-entrant shape on the handle.
Claim 3
Dependent Claim
56 words
A method according to claim 1 in which the filled moulds are introduced into a liquid freezant tank to a position where liquid in the moulds is above that in the liquid freezant tank, and are maintained in this position until the shape has set by the exterior of the liquid within the mould becoming frozen.
Claim 4
Dependent Claim
34 words
A method according to claim 2 in which the liquid in the mould is brought to the same level as that in the liquid freezant tank subsequent to the setting of the mould shapes.
Claim 5
Dependent Claim
18 words
A method according to claim 3 in which the liquids are levelled by withdrawing liquid from the moulds.
Claim 6
Dependent Claim
22 words
A method according to claim 3 in which the liquids are levelled by immersing the moulds further into the liquid freezant tank.
