  The ice container manufacturing device 1 according to the embodiment will be described below with reference to the drawings.

  As shown in FIG. 1, the ice container manufacturing device 1 according to the present embodiment includes an under cup 20 and a cap mold 30.

  As shown in FIGS. 1 to 4, the under cup 20 includes a cylindrical peripheral wall 21, a bottom lid 40 that closes one end of the peripheral wall 21 in the axial direction, and an opening 22 at the other end in the axial direction. ing. The opening 22 has a stepped portion 24 that fits with the cap mold 30 along the outer side of the edge.

  Further, the under cup 20 has a bottom plate 23 at a position facing the lid inner surface 43 of the bottom lid 40. The bottom plate 23 is a so-called partition plate that divides the space in the ice container manufacturing device 1 into a first space 2 in which an ice container is mainly formed and a second space 3 in which air is mainly stored. A hole 27 is provided in the center of the bottom plate 23. The first space 2 and the second space 3 are communicated with each other through a hole 27.

  More specifically, as shown in FIG. 4, the bottom plate 23 has a bulging portion 26 that bulges a part of the bottom plate 23 toward the first space 2 at the center thereof. The bulging portion 26 has a cylindrical extending wall 261 and a top portion 272 that continuously extend from the edge of the hole 27 of the bottom plate 23 toward the first space 2. Three slits 271 extending from the bottom plate 23 along the extending wall 261 to the top 272 are provided (see FIGS. 7 and 8).

  When manufacturing the ice container 50 using the ice container manufacturing apparatus 1 of the present embodiment, as will be described in detail later, as shown in FIG. 5, the protrusion 35 of the cap mold 30 is located in the freezer with the bottom lid 40 facing up. The ice container maker 1 is placed in the freezer so as to come into contact with the floor (not shown).

  As shown in FIG. 4, the first space 2 is formed between the undercup 20 and the cap mold 30 in a state where the undercup 20 and the cap mold 30 are fitted. The first space 2 is a bottomed cylindrical space for injecting water to form ice. The bottom portion of the first space 2 is designed to be thicker than other portions. In this way, by thickening the bottom of the first space 2, the bottom of the ice container 50 is made difficult to break, and the poured beverage allows the bottom to open earlier than the surrounding ice and open a hole. prevent.

  As shown in FIG. 4, the second space 3 includes a bottom plate outer surface 231, an extended wall outer surface 262, a surface of the top portion 272 on the bottom lid 40 side, and a bottom lid, with the bottom lid 40 closed. A space formed by the inner surface 43 of the lid 40 and the inner surface 25 of the peripheral wall. The second space 3 functions as a space for releasing the pressure accompanying the increase in the volume of water in the process of forming the ice container 50, which will be described later. Moreover, the 2nd space 3 functions as a heat insulation layer for freezing the water surface 54 vicinity lastly shown in FIG.

  By providing the bulging portion 26 on the bottom plate 23, as shown in FIG. 6, when the ice container 50 is formed, the ice in which the water in the second space 3 is iced and the ice in the first space 2 Are connected including the bulging portion 26. This prevents the ice container 50 from being easily detached from the undercup 20 and prevents the ice container 50 from rotating in the undercup 20. In particular, since the plurality of slits 271 extending in the axial direction along the extending wall 261 are provided in the hole 27 that connects the ice in the first space 2 and the ice in the second space 3, Ice in the two spaces 3 is firmly bonded through the three slits.

  In the ice container manufacturing device 1 according to the present embodiment, the holes for communicating the first space 2 and the second space 3 are the three slits 271, but the present invention is not limited thereto, and the first space 2 and the second space 3 are not limited thereto. The shape is not limited to this, as long as the holes can communicate with each other and can prevent the ice container 50 from rotating. For example, the position of the bottom plate 23 can be further shifted to the opening 22 side, and the bulging direction of the bulging portion 26 can be set to the second space 3 side. For the purpose of preventing the ice container 50 from rotating, the ice container 50 can be prevented from rotating by erecting the wing plate radially on the bottom plate 23 separately from the hole 27.

  Further, as shown in FIG. 4, a scale 28 indicating that an appropriate amount of water has accumulated is provided on the inner surface (extended wall outer surface 262) of the extended wall 261. The appropriate amount of water here refers to an appropriate air layer 52 in the first space 2 (FIG. 6) without overflowing even when the volume of the water changes to solid ice and its volume increases. This is the amount of water required to form ice in the state of having. Of course, in this state, since the ice includes the slits 271 provided in the bulging portion 26, the ice container 50 does not rotate.

  Further, by providing the scale 28, the user can be prevented from injecting water more than necessary, and an air layer can be formed in the first space 2 and the second space 3. The scale 28 is not limited to this. For example, when the under cup 20 is made of a transparent material, the scale 28 can be provided on the peripheral wall 21 of the under cup 20 (not shown).

  As shown in FIGS. 4 and 7, the bottom plate outer surface 231 of the bottom plate 23 is provided with a first inclined surface 232 that is inclined toward the first space 2 toward the hole 27. By providing the first inclined surface 232, when water 53 is injected from the second space 3 side, water droplets adhering to the periphery of the edge of the bottom plate outer surface 231 of the bottom plate 23 can also be efficiently used in the first space of the undercup 20. 2 can flow inside. In the present embodiment, three grooves are provided at equal intervals as the first inclined surface 232, but the number and interval of the grooves are not limited thereto.

  As shown in FIGS. 4 and 8, the bottom plate inner surface 234 of the bottom plate 23 has a substantially sector-shaped second inclined surface 233 inclined toward the second space 3 toward the hole 27. In addition, six radial drain grooves 251 (drain grooves) are provided on the inner surface 25 of the peripheral wall 21 of the under cup 20. The drainage groove 251 extends from the position below the lower end of the first frame 38 of the cap mold 30, which will be described later, to the bottom plate 23 in the vertical direction along the peripheral wall inner surface 25 in a state where the undercup 20 and the cap mold 30 are fitted together. Are provided linearly.

  Thereby, when the ice container 50 is used, the melted water flows to the air layer 52 along the drainage groove 251 by the pressure and heat applied to the undercup 20. Then, the water that has flowed to the air layer 52 flows to the hole 27 along the second inclined surface 233 of the bottom plate 23. The second inclined surface 233 is provided at a position facing the slit 271. For this reason, the water guided to the hole 27 through the second inclined surface 233 flows from the second inclined surface 233 to the slit 271. The water that has passed through the hole 27 in this way is accumulated in the second space 3.

  As described above, the water melted by the ice container 50 can be efficiently discharged into the second space 3, and the melted water from the vicinity of the opening 22 of the undercup 20 can be prevented from overflowing.

  In the present embodiment, six drain grooves 251 are arranged in the illustrated vertical direction along the peripheral wall inner surface 25 of the under cup 20, but the number of grooves is not limited thereto. For example, the drain groove 251 may be provided in a spiral shape on the inner peripheral surface 25 of the under cup 20.

  Further, the number of the second inclined surfaces 233 is not particularly limited, and can be appropriately adjusted in consideration of the number of slits 271 provided in the bulging portion 26 of the bottom plate 23. In this embodiment, since the second inclined surface 233 is provided on the bottom plate inner surface 234 side of the bottom plate 23 and the first inclined surface 232 is provided on the bottom plate outer surface 231 side, these two roles are exerted on the single bottom plate 23. The number of parts could be reduced.

  Next, the bottom lid 40 will be described.

  As shown in FIGS. 2 to 4, the bottom cover 40 is disposed to face the bottom plate outer surface 231 side of the bottom plate 23 and is detachably provided at one end of the peripheral wall 21.

  The bottom lid 40 has an annular fitting convex portion 41 that is inserted inside the circumferential wall 21 at one end of the circumferential wall 21, and a lid inner surface 43 that is inside the fitting convex portion 41. Moreover, the bottom cover 40 has an opening / closing protrusion 42 for facilitating the attachment / detachment of the bottom cover 40 on the periphery. The under cup 20 and the bottom lid 40 are fitted in close contact with each other to keep water tightness.

  The bottom lid 40 may be pushed from the second space 3 side due to an increase in air pressure in the second space 3 due to an increase in volume due to the water 53 inside the first space 2 icing. For this reason, it is preferable that the fitting convex part 41 of the bottom cover 40 has such a height that the bottom cover 40 cannot be removed even if the pressure in the second space 3 increases. As another method, when the internal pressure of the second space 3 rises above a certain level and the bottom cover 40 is lifted by a certain height, a hole for allowing the air in the second space 3 to escape outside is provided. It can also be provided in the fitting convex portion 41.

  Next, the cap mold 30 shown in FIGS. 1 to 4 will be described.

  The cap mold 30 is engaged with the undercup 20 to form a bottomed cylindrical first space 2. The cap mold 30 includes a bottomed cylindrical inner wall 32 that defines the inner surface of the first space 2, a cylindrical outer wall 31 that defines a part of the outer surface of the first space 2, and a bottom surface (bottom plate) of the first space 2. 23) and an annular top wall 33 that connects the inner wall 32 and the outer wall 31 that define the side away from the outer wall 31.

  The under cup 20 and the cap mold 30 are fitted so as to have a hermetic property such that water injected into the first space 2 does not leak. In order to maintain this hermeticity, a stepped portion 24 is provided outside the edge of the opening 22 of the undercup 20 so as to fit with the cap mold 30 along the edge.

  Corresponding to this, the edge of the outer wall 31 of the cap mold 30 has a stepped fitting step portion 36 protruding outward. The fitting step portion 36 has an annular fitting concave portion 37 for sandwiching the step portion 24 of the under cup 20 from inside and outside. As shown in FIG. 4, the fitting recess 37 is provided inside the fitting step portion 36, and a first frame 38 that contacts the inner surface of the edge of the opening 22 of the undercup 20, and the fitting step portion 36. A second frame 39 provided on the outer side and in contact with the stepped portion 24 of the undercup 20. Then, as shown in FIG. 4, the first frame 38 and the second frame 39 are fitted so as to sandwich the edge of the undercup 20 from inside and outside to form the first space 2.

  As shown in FIGS. 2 to 4, the inner wall 32 of the cap mold 30 is inserted and arranged inside the under cup 20 so as to define the inner surface of the first space 2 in a state of being fitted to the under cup 20. . Although it does not specifically limit about the protrusion length of the inner wall 32, If the amount is too short, the quantity of the drink accommodated in the ice container 50 will reduce. On the other hand, if it is too long, it may be too close to the bulging portion 26 of the undercup 20, and a hole may be opened in the bottom of the ice container 50, thus failing to serve as a container. For this reason, the protruding length of the inner wall 32 is appropriately adjusted depending on the capacity of the ice container 50 and the distance between the bulging portion 26.

  The top wall 33 has a plurality of protrusions 35 on the outer surface thereof. As will be described later, when the ice container 50 is manufactured, the cap mold 30 is placed downward and placed in the freezer (FIG. 5). At this time, by providing the protrusion 35 on the outer surface side of the top wall 33 of the cap mold 30, a gap is formed between the floor surface of the freezer and the top wall 33 of the cap mold 30, and the inner wall 32 is interposed via this gap. Outside air can be circulated efficiently inside.

  In the present embodiment, four protrusions 35 are provided, but the number and shape of the protrusions 35 are not limited thereto. For example, a plate-like wall may be provided along the top wall 33, and holes may be provided in the wall at regular intervals to form a fence. Also, the shape of the protrusion 35 is not a simple plate-like protrusion, but may be a cross when viewed in plan.

  In addition, the cap mold 30 according to the present embodiment has four knobs 34 for pinching when separated from the undercup 20. The knobs 34 are arranged radially with a constant interval outside the fitting step portion 36 of the outer wall 31. The knob 34 is provided with a non-slip 341 for preventing slipping when pinched. The position and number of the knobs 34 are not particularly limited. For example, a non-slip 341 provided on both surfaces of the knob 34, or a convex portion can be added to the tip of the knob 34. Moreover, it is good also as one disk-shaped protrusion connected to the perimeter of the outer wall 31.

  Next, the manufacturing method of the ice container 50 using the ice container manufacturing apparatus 1 mentioned above is demonstrated.

  First, as shown in FIG. 1, the undercup 20 and the cap mold 30 are fitted. Thereby, the first space 2 is formed. The fitting method is not particularly limited, but it is placed on a table so that the projection 35 of the top wall 33 of the cap mold 30 is on the bottom, and pressed from above to cap the step 24 of the opening 22 of the undercup 20. It is good to fit according to the fitting recess 37 of the mold 30. The bottom lid 40 is still removed at this time.

  After fitting the under cup 20 and the cap mold 30, the cap mold 30 is placed on the base with the top wall 33 facing downward (FIG. 5), and water 53 is poured from the second space 3 side of the under cup 20. Then, the water 53 is caused to flow into the first space 2 through the slit 271 of the bottom plate 23. As shown in FIG. 5, the water injection amount at this time is set to such an amount that the top portion 272 of the bulging portion 26 is immersed in the water 53. Specifically, water is poured to the position of the scale 28 (FIG. 5) provided on the extended wall outer surface 262 of the extended wall 261 of the bulging portion 26.

  After pouring the required amount of water 53, the bottom cover 40 is closed, and the first space 2 and the second space 3 are sealed. The ice container maker 1 filled with water 53 sufficient to form the ice container 50 is placed in a freezer so that the cap mold 30 faces down and frozen. The standard freezing time is about 12 hours in a general freezer for home use.

  After freezing, the ice container maker 1 is taken out of the freezer. The removed ice container manufacturing device 1 is immersed in water for a certain period of time. The reference time is such that the ice on the surface in contact with the outer wall 31 of the cap mold 30 can be melted, and is about 3 to 5 minutes with 25 ° water.

  Thereafter, the ice container manufacturing device 1 is taken out of the water. By immersing in water, a dissolved water layer is formed between the cap mold 30 and the ice container 50. In this state, the cap mold 30 is placed on a table such as a desk with the cap mold 30 facing down.

  The cap mold 30 is detached from the under cup 20 when the under cup 20 is pulled up while the knob 34 of the cap mold 30 of the ice container manufacturing device 1 placed on the table is pressed against the table by hand. In addition, the under cup 20 of the ice container manufacturing device 1 of the present embodiment also functions as a container holder after the ice container 50 is completed. For this reason, it is not necessary to prepare a container for containing the ice container 50 separately.

  Thereafter, when water is accumulated in the gap 51 (FIG. 6) between the ice container 50 and the under cup 20, the ice container 50 is turned upside down and wiped. The ice container 50 is now complete.

  Next, the process of forming ice in the ice container 50 of the ice container manufacturing device 1 shown in this embodiment will be described.

  The ice container manufacturing device 1 according to the present embodiment includes a first space 2 that forms an ice container 50 and a second space 3 having an air layer. The ice container maker 1 filled with the required amount of water 53 is placed in the freezer with the cap mold 30 facing down. By making the cap mold 30 ice down, ice is formed so that the top wall 33 of the cap mold 30 is the bottom and the vicinity of the bottom plate 23 is the upper surface (water surface 54). For this reason, since the part which contacts the mouth of the ice container 50 is iced without gap according to the round shape of the top wall 33, the mouthfeel of the ice container 50 can be made smooth.

  In order to form a beautiful bottomed cylindrical ice container 50 having an inner surface shape that follows the shape of the inner wall 32 of the cap die 30 and an outer surface shape that follows the shape of the outer wall 31 of the cap die 30, It is necessary that the water 53 in the cylindrical portion of the space 2 be evenly cooled from the inner wall 32 side and the outer wall 31 side of the cylinder. If the freezing speed of the water 53 on the outer wall 31 side is faster than the freezing speed on the inner wall 32 side, the stress caused by the volume that increases when the water 53 freezes is directed inward, and the inner wall 32 of the cap mold 30 is deformed. There is a risk. In addition, the ice container 50 may be cracked.

  Therefore, in the present embodiment, the projection 35 is provided on the top wall 33 of the cap mold 30 in order to guide cold air to the inner wall 32 side of the cap mold 30. Thereby, it is possible to prevent a temperature difference between the air on the inner wall 32 side and the air on the outer wall 31 side, and the water 53 in the first space 2 is cooled almost uniformly from both sides of the inner wall 32 side and the outer wall 31 side. can do.

  In addition, as shown in FIG. 5, the ice container maker 1 is provided with an air layer between the water surface 54 and the bottom lid 40. This layer of air functions as a heat insulating layer when the ice container maker 1 is frozen. For this reason, after putting the ice container manufacturing device 1 in the freezer, the water 53 in the first space 2 starts to ice first from the cylindrical portion sandwiched between the outer wall 31 and the inner wall 32 of the cap mold 30. And the part which hits the bottom of the ice container 50 begins to freeze, and finally the water 53 near the water surface 54 is frozen. Accordingly, the peripheral portion of the second space 3 (the bottom side of the ice container 50) is finally frozen.

  As a first effect of such an ice formation process, bubbles contained in the injected water can be efficiently discharged. That is, the water 53 just injected into the ice container maker 1 contains a lot of air. These air bubbles are attached to the undercup 20 and the cap mold 30. Part of the air is dissolved in the water 53. In the ice container manufacturing apparatus 1 of the present embodiment, since the water surface 54 is iced last, the air adhering to the undercup 20 and the cap mold 30 can be removed along with the freezing of the water 53, and the air is directed toward the water surface 54. To rise. At this time, since the water surface 54 is not iced, air can be discharged.

  Furthermore, as a second effect, the air layer (including the space 52 of the first space 2) in the second space 3 also functions as a space for absorbing the increase in volume when the water 53 is frozen. . As a result, it is possible to prevent a problem that the inner wall 32 of the cap mold 30 is deformed by the ice that has lost its escape location in the first space 2 being squeezed out to the second space 3 side. Further, by providing such an air layer, it is possible to prevent the ice container 50 from being deformed due to the fitting between the under cup 20 and the cap mold 30 due to the pressure when the water 53 is frozen. .

  In addition, this invention is not limited to said embodiment. For example, the shape of the under cup 20 and the cap mold 30 of the ice container manufacturing device 1 shown in the present embodiment is not limited to this, and any shape that can withstand a pressure change accompanying an increase in the volume of water due to cooling and freezing may be used.

  In the ice container manufacturing device 1 shown in the present embodiment, the under cup 20 is manufactured from polypropylene, and the cap mold 30 and the bottom lid 40 are manufactured from polyethylene. However, these materials are not limited thereto. For example, the under cup 20 can be made of polyethylene or silicon, and the cap mold 30 and the bottom lid 40 can be made of a cold-resistant resin material such as polypropylene, polycarbonate, or silicon. Further, in the present embodiment, the undercup 20, the cap mold 30, and the bottom lid 40 are fitted and brought into close contact with each other by pressure. However, as another method, a screw or the like can be used.

  Moreover, although the ice container 50 shown to this embodiment was manufactured using water as a liquid, it is also possible to manufacture an ice container using another drink.

  Of course, various modifications can be made without departing from the scope of the present invention.
