It is explanatory drawing which shows the manufacturing process of the container with the enclosure of Example 1. FIG. It is explanatory drawing which shows the manufacturing process of Example 2 of the container with the to-be-enclosed body of this invention.

  Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a perspective view showing Example 1 of an encapsulated body-containing container according to the present invention, and a part thereof is shown in a longitudinal section. The container 1 to be encapsulated in the first embodiment includes a case 3 constituted by a bottomed container having an opening 2 and a closing member 4 for closing the opening 2 of the case 3.

  The case 3 is made of stainless steel and is formed in a bottomed cylindrical shape having a hollow portion 5 that opens upward. The hollow portion 5 which is the inside of the case 3 is communicated with the outside of the case 3 through the opening 2. The hollow portion 5 of the case 3 is filled with a liquid or gel encapsulated body 6 through the opening 2.

  The encapsulated body 6 may be anything that can be frozen, and is water in the first embodiment. The water 6 is frozen while being filled in the case 3. For example, the case 3 filled with water 6 may be accommodated in a freezer and the water 6 may be frozen by cold air in the freezer.

  The closing member 4 is made of stainless steel and is formed in a bottomed short cylindrical shape having a hollow portion 7 that opens downward. The closing member 4 is formed such that its vertical length is smaller than the vertical length of the case 3. The hollow portion 7 which is the inside of the closing member 4 is communicated with the outside of the closing member 4 through the opening 8.

  The closing member 4 is joined to the case 3 in a state where the water 6 is frozen. Specifically, the opening 2 of the closing member 4 and the opening 8 of the closing member 4 are closed to each other by joining the opening 8 of the closing member 4 to the opening 2 of the case 3 by friction welding. Thereby, the container 1 with the to-be-sealed body with which the water 6 was enclosed can be formed. The container 1 to be encapsulated in Example 1 is typically manufactured as follows.

  2 and 3 are diagrams illustrating an example of a method for manufacturing the container 1 to be encapsulated according to the first embodiment, FIG. 2 is a flowchart, and FIG. 3 is an explanatory diagram illustrating a manufacturing process. As shown in these drawings, in the manufacturing method of the container 1 to be encapsulated in the first embodiment, the molding step S1, the filling step S2, the freezing step S3, the joining step S4, and the finishing step S5 are sequentially performed.

  The molding step S1 is a step of forming the bottomed cylindrical case 3 and the bottomed cylindrical closure member 4. Typically, the case 3 and the closing member 4 are integrally formed separately by cutting. The forming step S1 can be omitted by using a commercially available bottomed cylindrical member as the case 3 and the closing member 4.

  The filling step S2 is a step of filling the case 3 with water 6. Typically, water 6 is poured into the hollow portion 5 of the case 3 through the opening 2 and filled. As shown in FIG. 3, when the water 6 is filled, a gap that is not filled with the water 6 is formed at the upper end of the hollow portion 5. Thereby, it is possible to prevent the frozen water 6 from bulging outward from the hollow portion 5 when the water 6 is frozen.

  The freezing step S3 is a step of freezing the water 6 in the case 3 in a state where the water 6 is filled in the case 3. Typically, as described above, the case 3 filled with the water 6 is housed in a freezer and the water 6 is frozen by the cold air in the freezer. At this time, the water 6 in the case 3 may be completely frozen, but it is sufficient that at least the surface of the water 6 is frozen.

  The joining step S4 is a step of joining the closing member 4 to the opening 2 of the case 3 by friction welding so as to close the opening 2 of the case 3 in a state where the water 6 is frozen. In this friction welding, frictional heat is generated by rubbing the members to be joined together, the members are joined by softening and pressing the members by the frictional heat, and a known friction welding device is used. It is done.

  In the first embodiment, the opening 8 of the closing member 4 is joined to the opening 2 of the case 3 by friction welding in a state where the case 3 and the closing member 4 are arranged so that the axial direction is along the vertical direction. . Specifically, the closing member 4 is joined to the case 3 by rotating the closing member 4 about its axis while the lower end portion of the closing member 4 is pressed against the upper end portion of the case 3. Thereby, the opening part 2 of case 3 and the opening part 8 of the closure member 4 can be obstruct | occluded mutually.

  The finishing step S5 is a step of polishing the case 3 and the closing member 4 joined by friction welding. In the above-described joining step S4, burrs are generated at the joining portion between the case 3 and the closing member 4 by friction welding. In the finishing step S5, burrs generated at the joint between the case 3 and the closing member 4 are removed by polishing, and the outer surfaces of the case 3 and the closing member 4 are smoothed by polishing.

  In this way, the container 1 to be encapsulated in Example 1 can be manufactured. The use of the container 1 to be encapsulated is not particularly limited. For example, the container 1 to be encapsulated is stored in a freezer and the internal water 6 is frozen. Typically, it is used when the container 1 containing the encapsulated body in which the water 6 inside is frozen is placed in the beverage to keep the beverage cold. It can also be used as a food that is placed under food such as sashimi to keep food cold. That is, the container 1 to be encapsulated can be used instead of ice.

  According to the manufacturing method of the container 1 to be encapsulated and the container 1 to be encapsulated in the first embodiment, the closing member 4 is joined to the case 3 by friction welding, which is compared with mere welding or joining by an adhesive. And it can join more reliably. Further, according to the first embodiment, the hollow portion 5 of the case 3 and the hollow portion 7 of the closure member 4 are joined by friction welding in a state where the water 6 in the hollow portion 5 of the case 3 is frozen. It is possible to prevent the air in the space formed by the expansion due to the frictional heat at the time of joining. Thereby, it is possible to prevent a bonding failure between the case 3 and the closing member 4, and it is possible to more reliably join the closing member 4 to the case 3. Therefore, according to the first embodiment, the opening 2 of the case 3 and the opening 8 of the closing member 4 can be closed more reliably, and the joint portion between the case 3 and the closing member 4 is used during use. Therefore, it is possible to prevent the internal water 6 from leaking out.

  Next, a manufacturing method of a container with an encapsulated body and Example 2 of the container with an encapsulated body of the present invention will be described. The manufacturing method of the encapsulated body-containing container 1 and the encapsulated body-containing container 1 according to the second embodiment basically have the same configuration as that of the first embodiment. Therefore, in the following description, the differences between the two will be mainly described, and corresponding portions will be described with the same reference numerals.

  FIG. 4 is an explanatory view showing an example of the manufacturing process of Example 2 of the container to be encapsulated according to the present invention. In the second embodiment, not only the case 3 but also the closing member 4 constituted by the bottomed container having the opening 8 is filled with the encapsulated body 6. That is, in the first embodiment, the closing member 4 is joined to the case 3 filled with the water 6, but in the present embodiment 2, the closing member 4 filled with the water 6 into the case 3 filled with the water 6. Are joined.

  The closing member 4 of the second embodiment is made of stainless steel and is formed in a bottomed cylindrical shape having a hollow portion 7 that opens downward. The hollow portion 7 which is the inside of the closing member 4 is communicated with the outside of the closing member 4 through the opening 8. The hollow portion 7 of the closing member 4 is filled with water 6 through the opening 8. For example, the water 6 is frozen by the cold air in the freezer by housing the closing member 4 filled with the water 6 in the freezer.

  As described above, the opening 8 of the closing member 4 in the state where the water 6 is frozen is joined to the opening 2 of the case 3 where the water 6 is frozen as described above by friction welding. Thereby, the opening part 2 of the case 3 and the opening part 8 of the closure member 4 are mutually closed, and the container 1 with an enclosure to be sealed with water 6 can be formed. The container 1 to be encapsulated in the second embodiment is also basically subjected to the molding step S1, the filling step S2, the freezing step S3, the joining step S4, and the finishing step S5 in the same manner as in the first embodiment.

Water 6 is poured through 8 and filled. At this time, a gap not filled with water 6 is formed at the upper end of the hollow portion 7 of the closing member 4.

  In the freezing step S3 of the second embodiment, in addition to the work performed in the freezing step S3 of the first embodiment, the water 6 in the closing member 4 is frozen while the water 6 is filled in the closing member 4. . This is done, for example, by storing in a freezer as in the case 3. Note that at least the surface of the water 6 in the closing member 4 may be frozen.

  In the joining step S4 of the second embodiment, the opening 8 of the closing member 4 is joined to the opening 2 of the case 3 by friction welding while the water 6 in the case 3 and the water 6 in the closing member 4 are frozen. Thus, the opening 2 of the case 3 and the opening 8 of the closing member 4 are closed. In the second embodiment, friction welding is performed using a known friction welding apparatus, and at the time of the friction welding, the opening 2 of the case 3 and the opening 8 of the closing member 4 are configured to open in the lateral direction. . Specifically, the opening 8 of the closing member 4 is joined to the opening 2 of the case 3 by friction welding in a state where the case 3 and the closing member 4 are arranged so that the axial direction is along the left-right direction. That is, the closing member 4 is joined to the case 3 by rotating the case 3 around its axis and pressing the opening 8 of the closing member 4 in contact with the opening 2 of the case 3. In the finishing step S5, burrs generated in the joining step S4 are removed by polishing, and the outer surfaces of the case 3 and the closing member 4 are polished and smoothly formed.

  According to the method for manufacturing the container 1 to be encapsulated and the container 1 to be encapsulated in Example 2, the water 6 in the case 3 is frozen, and the frozen water 6 is adhered and fixed to the case 3. be able to. Further, by freezing the water 6 in the closing member 4, the frozen water 6 can be adhered and fixed to the closing member 4. Thus, when the opening 2 of the case 3 and the opening 8 of the closing member 4 are joined in a state where the case 3 and the closing member 4 are arranged along the left-right direction, the opening 2 of the case 3 is joined. In addition, the water 6 can be prevented from spilling from the opening 8 of the closing member 4. In addition, when the case 3 is rotated, the water 6 in the case 3 can be prevented from splashing from the opening 2 to the outside. Thereby, a predetermined amount of water 6 can be sealed inside the container 1 to be sealed.

  Further, according to the second embodiment, the closing member 4 is joined to the case 3 by friction welding, so that the joining can be performed more reliably than simple welding or joining by an adhesive. Furthermore, according to the second embodiment, the hollow portion 5 of the case 3 and the closing member 4 are joined by friction welding while the water 6 in the case 3 and the water 6 in the closing member 4 are frozen. It is possible to prevent the air in the space formed by the hollow portion 7 from expanding. Therefore, the opening 2 of the case 3 and the opening 8 of the closing member 4 can be closed more reliably, and the water 6 leaks from the joint between the case 3 and the closing member 4 during use. Can be prevented.
