TECHNICAL FIELD OF THE INVENTION
The present invention relates to a container for forming spherical on-the-rock transparent ice in a general household freezer.
[0002]
[Prior art]
Conventionally, to make ice in a general household freezer, an ice tray attached to the freezer is used. This ice tray was made of metal or synthetic resin, and it was customary to make a substantially cubic ice by inserting a partition inside. However, the ice made in such ice trays does not become transparent and bubbles remain in the ice and often become cloudy.
[0003]
As a prior art for producing a bubble-free transparent spherical ice for on-the-rock, Patent Literature 1 discloses a method of starting ice formation from above an ice maker by using an insulating material and an air layer included in an ice maker outer tray, and forming an ice tray and an upper lid. After purifying the transparent ice in the first ice-making chamber formed in the above, the turbid air bubbles are trapped in the second ice-making chamber through the small holes to freeze ice, and then the transparent on-the-air purified in the first ice-making chamber is formed. There is a description about an ice maker that takes out ice for rock.
[0004]
In addition, Non-Patent Document 1 describes a container for making spherical ice, and the outline of the shape and structure is shown in FIGS. 6 and 7.
This container comprises a cylindrical outer cup 27 'with a bottom, an inner cup body 21', a lower spherical shell 11 'and an upper spherical shell 1', and the spherical first ice chamber 31 is formed by assembling these members. , A second ice-making chamber 32 ′, and an air layer 33 ′ surrounding the side surface and bottom surface of the second ice-making chamber 32 ′. Water is supplied to the first ice-making chamber 31 ′ and the second ice-making chamber 32 ′. Fill and freeze in the freezer.
[0005]
By providing the air layer 33 ', icing starts from the upper part of the first ice making chamber 31', and the icing gradually progresses downward, but the bubbles contained in the water are accompanied by the uniced water due to the volume expansion due to the icing. And moves to the second ice making chamber 32 'through a small hole 13' opened at the bottom of the lower hemispherical shell 12 'of the lower spherical shell 11'. The substantially central portion is clouded by bubbles 34 '.
[0006]
Then, the lower part 11 'of the spherical shell and the upper part 1' of the spherical shell assembled by the fitting portion (the locking peripheral strip 16 'and the locking peripheral piece 4') are connected to the knob 7 'attached to the upper part 1' of the spherical shell. The spherical ice lower part 11 'and the spherical shell upper part 1' are relatively disassembled by using, and the spherical ice is taken out and used.

[Problems to be solved by the invention]
However, in the container shown in FIGS. 6 and 7, there is no means for easily separating the upper part of the spherical shell and the lower part of the spherical shell assembled in an undercut shape at the fitting part. It is necessary to release the ice in the gap or the ice between the upper hemisphere shell or the lower hemisphere shell and the spherical ice sufficiently, and it takes time and effort to suspend water or leave it for several minutes, Requires considerable power.
[0009]
Therefore, the present invention has been made to solve the above-mentioned problems in the prior art, and an object of the present invention is to provide a spherical ice manufacturing container that can easily and quickly take out spherical ice after ice making.
[0010]
[Means for Solving the Problems]
In the present invention for solving the above technical problems, the means of the invention described in claim 1 is:
Having a bottomed cylindrical outer cup,
Having an inner cup body in which an outer cylinder is erected from the upper end of a bottomed cylindrical inner cup via an outer flange peripheral piece,
An inner cylinder is erected from the upper end of the lower hemispherical shell having a plurality of small holes formed at the bottom via a flange peripheral piece, and the lower part of the spherical shell is provided with a rectangular lower flange from the upper end of the inner cylinder. Having
An air hole is formed at the top, and the lower hemispherical shell is tightly fitted in an undercut shape so as to be rotatable, and an upright cylinder is erected from the periphery near the lower end of the outer surface of the upper hemispherical shell forming the spherical shell. A state in which the upper surface of the upright cylinder has a spherical shell upper portion with a rectangular upper flange attached to the upper edge, the lower surface of the outer flange peripheral piece abuts the upper end surface of the outer cup, and the inner cup is housed in the outer cup. In that, an air layer surrounding the side and bottom of the inner cup is formed,
A first ice making chamber is formed in the spherical shell;
With the lower surface of the lower flange in contact with the upper end surface of the outer cylinder, the spherical shell is housed in the upper portion of the inner cup body, and the second ice making chamber is formed by the inner cup and the lower hemispherical shell,
With the corners of the upper and lower flanges shifted from each other, pull up the corners of the upper flange and use them as knobs,
It is in.
[0011]
The container having the above configuration according to claim 1 has members of a spherical shell upper part, a spherical shell lower part, an inner cup body and an outer cup. Used as a container for manufacturing.
That is,
1. The inner cup is housed in the outer cup in a state where the lower surface of the outer flange peripheral piece is in contact with the upper end surface of the outer cup, and water is poured up to the outer cylinder set up on the upper part of the inner cup.
2. The upper and lower spherical shells are rotatably tightly fitted in an undercut shape, and the upper and lower hemispherical shells form a spherical shell to form a spherical first ice chamber.
3.1. 1. Inside the cup with water Push the spherical shell until it stops. At this time, the lower limit of the pushing is determined by the lower flange attached to the inner cylinder below the spherical shell abutting on the upper end surface of the outer cylinder of the inner cup body.
4. Water mainly fills the interior of the spherical shell (first ice chamber) through small holes formed at the bottom of the lower hemispherical shell, while allowing air to escape from the air holes formed at the top of the upper hemispherical shell.
[0012]
When the components are assembled as described above and placed in a freezer with water therein, icing starts from the upper part of the first ice making chamber due to the effect of the air layer surrounding the side surface and the bottom of the inner cup. The air bubbles gradually move downward, but the bubbles contained in the water move to the second ice making chamber through the small holes of the lower hemisphere shell with the water that has not been frozen due to the volume expansion due to the ice formation. A substantially central portion of the second ice-making chamber where ice is formed is clouded by bubbles, but transparent and spherical ice without bubbles is formed in the first ice-making chamber.
[0013]
Although the volume expands as the freezing progresses, in the first ice making chamber, water mainly flows out of the small holes into the second ice making chamber, and in the second ice making chamber, the spherical shell moves slightly upward in the inner cup body. This volume expansion is absorbed.
[0014]
Next, in order to remove the spherical ice formed in the first ice making compartment, the outer cup is removed from the container, water is gently applied to the whole, and the inner cup body is removed together with the ice in the second ice making compartment.
[0015]
Next, the upper part of the spherical shell is removed from the lower part of the spherical shell.However, in the conventional container, there is no means for easily separating the upper part of the spherical shell and the lower part of the spherical shell, and freezing in the gap such as the fitting portion, the upper hemispherical shell or the lower hemispherical shell. In order to sufficiently release the icing from the spherical ice, it takes time and effort to suspend water for several minutes or leave it for several minutes, and it requires considerable power.
[0016]
In the configuration of the first aspect, the upper flange of the upper spherical shell and the lower flange of the lower spherical shell are rotated to shift the positions of the corners thereof by shifting the positions of the upper flange at the upper part of the spherical shell. The corner of the flange can be pulled up and used as a knob, and by using this knob, the upper and lower shells fitted in an undercut shape can be easily separated in a short time. .
[0017]
If the upper flange of the upper part of the spherical shell and the lower flange of the lower part of the spherical shell have the same peripheral shape, by placing both flanges in the same direction, it is possible to compactly pack, pack, transport and display the product. Can be.
[0018]
In addition, since the rotation of the upper flange after ice making requires a relatively large amount of force due to icing, before use, the corners of the upper flange and the lower flange must be set in advance so that they can function as pull-up knobs. It is preferable to assemble the container in a shifted state.
[0019]
In addition, by displacing in advance as described above, the upper part of the spherical shell and the lower part of the spherical shell are relatively finely moved in a reciprocating manner by hooking a finger on the corner side of the upper flange. In addition, it is possible to reduce the freezing of the spherical ice and the upper hemispherical shell or the lower hemispherical shell and the freezing of the fitting portion.
[0020]
According to a second aspect of the present invention, in the first aspect, the peripheral shapes of the upper flange and the lower flange are substantially square.
[0021]
According to the second aspect of the present invention, the peripheral shape of the upper flange is substantially square, so that packaging and storage are facilitated, and a sufficient allowance for the pull-up knob can be secured.
[0022]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
1 to 5 show an embodiment of a spherical ice manufacturing container according to the present invention. The container of this embodiment is composed of five members, an outer cup 27, an inner cup body 21, a lower spherical shell 11, and an upper spherical shell 1. You.
[0023]
The outer cup 27 has a bottomed cylindrical shape, and the inner cup body 21 has an outer flange peripheral piece 23 on the upper end of a bottomed cylindrical inner cup 22 having both a smaller height and a smaller body diameter than the outer cup 27. The outer tube 24 is erected through the outer tube, and a fitting tube piece 25 that fits into the upper end portion of the outer cup 27 from the lower surface of the outer flange peripheral piece 23 and the vicinity of the peripheral edge is vertically provided.
[0024]
The spherical shell lower part 11 has a lower hemispherical shell 12 in which a plurality of small holes 13 are formed at the bottom, and forms a locking peripheral shape 16 on the inner surface from the upper peripheral edge of the lower hemispherical shell 12 via a flange piece 14, At the upper end of the inner cup 22, a locking cylinder piece 15 gently inscribed is erected, and further from the upper end of the locking cylinder piece 15 to the outer cylinder 24 of the inner cup body 21 via the flange peripheral piece 18. An inner cylinder 17 that is in contact with the inner cylinder 17 is erected, and a lower flange 19 whose outer peripheral shape is substantially square is attached to the upper end of the inner cylinder 17 in an outer flange shape.
[0025]
The upper part 1 of the spherical shell has an upper hemispherical shell 2 having an air hole 3 formed at the top, and the lower peripheral edge of the outer surface of the upper hemispherical shell 2 is engaged with the engaging periphery 16 of the lower part 11 of the spherical shell. A stopper piece 4 is provided around and a cylindrical upright cylinder 5 is erected from directly above the locking peripheral piece 4. This is a configuration in which an upper flange 6 which is the same as 19 is provided in an outer flange shape.
[0026]
Next, an example of an assembling procedure for use in ice making will be described.
The inner cup body is inserted into the outer cup 27 in a state where the fitting cylinder piece 25 is fitted into the upper end of the outer cup 27, the peripheral edge of the outer flange peripheral piece 23 is brought into contact with the upper end face, and the inner cup 22 is housed inside. Then, water is poured into the inner cup body 21 up to the outer cylinder 24.
At this time, an air layer 33 is formed so as to surround the side surface and the bottom of the inner cup 22.
[0027]
The spherical shell upper part 1 and the spherical shell lower part 11 are tightly assembled rotatably in an undercut shape by the locking peripheral piece 4 and the locking peripheral shape 16, and the spherical shell 9 is formed by the upper hemispherical shell 2 and the lower hemispherical shell 12. Then, the inside becomes a spherical first ice making chamber 31. At this time, the upper flange 6 and the lower flange 19 are assembled in such a manner that the directions thereof are shifted by 45 °. (The state shown by the two-dot chain line in FIG. 2)
[0028]
Next, the spherical shell 9 is slowly pushed into the upper portion of the inner cup body 21 containing water. At this time, the spherical shell 9 is positioned inside the upper portion of the inner cup body 21 at the pushing limit position determined by the contact between the lower flange 19 of the spherical shell lower part 11 and the upper end surface of the outer cylinder 24 of the inner cup body. A second ice chamber 32 is formed below the hemispherical shell 12.
[0029]
In addition, by pushing the inner cylinder 17 into the outer cylinder 24 while being gently inscribed, positioning of the pushing can be performed, and smooth pushing can be performed.
[0030]
In the above-mentioned pushing process, water enters the first ice making chamber through the small holes 13 formed at the bottom of the lower hemisphere shell 12 while allowing air to escape from the air holes 3 formed at the top of the upper hemisphere shell 2. , Filling the interior of the spherical shell 9.
[0031]
When the components are assembled as described above and the container is installed in the freezer in a state where water is filled, icing from the upper portion of the first ice making chamber 31 due to the effect of the air layer 33 surrounding the side and bottom of the inner cup 22. Begins, and the icing gradually progresses downward, but the bubbles contained in the water pass through the small holes 13 of the lower hemispherical shell 12 with the uniced water due to volume expansion due to icing and enter the second ice making chamber 32. As a result, the substantially central portion of the second ice-making chamber 32, which freezes the ice at the latest, becomes clouded by the bubbles 34, but in the first ice-making chamber 31, transparent and spherical ice without bubbles is formed.
[0032]
In the second ice making chamber 32, the whole spherical shell 9 moves upward in the inner cup body 22 to absorb the volume expansion due to ice formation.
[0033]
Next, in order to remove the spherical ice formed in the first ice making chamber 31, the outer cup 27 is removed from the container, water is applied to the whole, and the inner cup body is removed together with the ice in the second ice making chamber 32.
[0034]
Next, the upper part 1 of the spherical shell is removed from the lower part 11 of the spherical shell. At this time, since the upper flange 6 of the upper part 1 of the spherical shell is shifted from the lower flange 19 of the lower part 11 of the rectangular spherical shell by 45 °, the corners thereof are formed. Can be easily removed in a short period of time by using it as a pull-up piece 8 and pulling it up with a finger.
[0035]
Further, the upper ice shell 2 and the lower hemisphere shell 12 are relatively finely moved in a reciprocating manner by hooking a finger on the side of the pull-up knob 8 so that the spherical ice and the upper hemisphere shell 2 or the lower hemisphere shell 12 are moved. Icing and the icing of the fitted portion can be eased, and the lifting operation using the lifting knob 8 becomes easier.
[0036]
【The invention's effect】
The present invention has the above-described configuration, and has the following effects.
According to the first aspect of the present invention, the spherical ice after ice making can be easily and quickly taken out by using the corner of the upper flange attached to the upper part of the container as a pull-up knob.
[0037]
According to the second aspect of the present invention, by making the peripheral shape of the upper flange substantially square, it is easy to pack and store, and it is possible to secure a sufficient margin for picking with a finger.
