ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a device for ladling an ice cream ball.
2. Description of the Related Art
Referring to
FIG. 1
, a conventional device
1
for ladling ice cream ball comprises a semicircle cup
11
, a first handle
12
, a pin
13
, a spring
14
, a rod
15
, a knife
16
, a fixed element
17
and a second handle
18
. The semicircle cup
11
is connected to the first handle
12
and the second handle
18
. The pin
13
passes through the spring
14
. The spring
14
comprises two ends
141
respectively placed in the first handle
12
and the second handle
18
. The first handle
12
comprises an extending portion
121
extending from the bottom of the first handle
12
. The second handle
18
comprises a serration portion
182
. An upward flange
123
hooks with a projection
184
. The rod
15
comprises a gear
151
connected to the serration portion
182
. The knife
16
is mounted inside of the semicircle cup
11
. A top end of the knife
16
is fixed on a top end of the semicircle cup
11
by the fixed element
17
. A down end of the knife
16
is connected to the rod
15
.
The device
1
is used to takes an ice cream ball. When the first handle
12
and the second handle
18
are forced inwardly, the serration portion
182
rotates the gear
151
, then rotates the rod
15
so that the knife
16
is driven to rotate along an inside edge of the semicircle cup
11
so as to separate the ice cream ball from the semicircle cup
11
. The elasticity of the spring
14
is able to drive the first handle
12
and the second handle
18
outwardly and to rotate the knife
16
return to the original position.
It is found that such a device
1
has shortcomings as follows.
1. The structure is too complex. The device
1
has too many elements so that the cost for manufacturing the device
1
is expensive.
2. It is difficult to clean the device
1
. Because the back of the knife
16
is closed to the semicircle cup
11
, there is a dead portion that is unable to clean completely.
SUMMARY OF THE INVENTION
One objective of the present invention is to provide a device for ladling an ice cream ball comprising a first portion and a second portion. The first portion has a first piece, a first connecting section and a first handle. The first handle has a first slot. The first connecting section is located between the first piece and the first handle. The second portion has a second piece, a second connecting section and a second handle. The second handle has a second slot. The second connecting section is located between the second piece and the second handle. The second connecting section is connected to the first connecting section by a pin. After the first connecting section connects to the second connecting section, the first piece connects to the second piece, and the first piece and the second piece are formed a cup to take an ice cream ball. A spring has two extending ends respectively placed in the first slot and the second slot. When the first handle and the second handle are forced inwardly, the cup is separated as the first piece and the second piece for separating the ice cream ball.
Another objective of the present invention is to provide a device for ladling an ice cream ball, comprising, a first portion having a first piece, a first connecting section and a first handle, the first handle having a first slot, the first connecting section being located between the first piece and the first handle, the first piece having a spherical sector contour having a first predetermined diameter dimension; a second portion having second piece, a second connecting section, and a second handle, the second handle having a second slot, the second connecting section being located between the second piece and the second handle, the second connecting section being connected to the first connecting section by a pin, the second piece having a spherical sector contour having a second predetermined diameter dimension, the second predetermined diameter dimension being greater than the first predetermined diameter dimension so that a portion of the second piece overlaps a corresponding portion of the first piece to form a semispherical cup as the first and second pieces are brought together to collect an ice cream ball therein; and, a spring disposed in a space formed between the first and second connecting sections and having two extending ends respectively placed in the first slot and the second slot; thereby when the first handle and the second handle are forced inwardly, the cup is opened as the first piece and the second piece are separated from each other for separating the ice cream ball thereform.
The device of the invention has the following advantages:
1. The structure of the device is simple. The device of the invention has few elements. Therefore, the device of the invention can be manufactured easily. The cost of the device is cheap.
2. It is easy to clean the device. Because the elements of the device are few, there is no dead portion between the elements.
