Title: An apparatus for squeezing and sieving
Inventor: HASMAH MOHIDIN
Filed: 2010-09-02
Abstract: An apparatus (100) for squeezing and sieving a liquid extract out from a food product is disclosed. More particularly, the apparatus (100) is used to extract coconut milk from coconut meat. The apparatus (100) comprises of two cups (110,120), one slightly bigger than the other such that the smaller cup (110) can be placed into the bigger cup (120) to form a gap (130) between the outer surface of the smaller cup (110) and the inner surface of the bigger cup (120). The cups (110,120) are attached to each other by a pivot (140), which is a hinging mechanism, such that the smaller cup (110) can be removed or placed into the bigger cup (120). The hinging mechanism is preferably attached to a ring element (102) of the cups that forms the circumference of the cup. Also attached to each of the ring element of the cups is a handle (150) in which the user grips and presses to compress the smaller cup (110) against the bigger cup (120) when a certain food product is placed in the gap (130). When in use, the compression of the cups (110,120) causes the liquid extract of a food product to ooze out from the body (110a,110b) of the cups.
