Japanese Patent Laid-Open No. 10-167278

  However, a beverage container such as the above-described conventional beer barrel container needs to clean a metal container body having a large volume and weight in order to be used repeatedly, and the cleaning cost increases. Further, the metal material of the container body must be determined in consideration of the resistance of the cleaning agent and the like, and the cost of the container itself is increased.

  The present invention has been made in view of such circumstances, and provides a returnable beverage container that does not require washing or can reduce washing of the container.

The beverage container according to the present invention has an outer container in which an opening first mouth is formed at the upper end, and an inner container in which an opening second mouth is formed in the upper end and is accommodated in the outer container. When, wherein the removable and becomes the first mouth portion, the second way mouth abuts from the inside to the first mouth portion, the second opening portion the first mouth portion third mouth you fixed and a lid formed, the lid is releasably sealed to said second opening portion with said first mouth portion relative to the second The tip of the mouth is sandwiched between the outer surface of the step formed on the outer edge of the lid and the inner surface of the step formed on the first mouth, and the second mouth is It becomes the structure fixed to the 1 mouth part .

With such a configuration, the second mouth portion of the inner container accommodated in the outer container is fixed to the first mouth portion with a detachable lid , and the first mouth portion and the second mouth portion. There therefore comes to be blocked by the third mouth the lid body formed of, it becomes possible out of the beverage into the inner vessel through the third mouth of the lid, removable of the lid Thus, the inner container accommodated in the outer container can be exchanged.

Then, a function as a mouth portion fixing member lid, a second mouth portion of the inner container housed in the outer container by attaching the lid to the first mouth of the outer container is first Therefore, the number of parts of the beverage container can be reduced, and the structure can be made simpler.

  Further, in the beverage container according to the present invention, the lid body has a shape that can enter from a circular opening of the first mouth portion, and a screw thread formed on an outer peripheral surface of the lid body has the first mouth portion. The first mouth portion is formed on each of the inner peripheral surface of the first mouth portion and the outer peripheral surface of the lid body. A portion that sandwiches the second mouth portion that is in contact with the inside of the second mouth portion may be formed.

  With such a configuration, when the lid is screwed so as to fit into the first mouth of the outer container from the opening, the second mouth of the inner container housed in the outer container becomes the first mouth. And the first mouth and the second mouth can be closed by the lid.

  Further, in the beverage container according to the present invention, the lid body has a shape covering the first mouth part which is a circular opening, and a screw thread formed on an inner peripheral surface thereof is the first mouth part. A peripheral edge that forms a circular opening of the first mouth and a portion of the lid that covers the peripheral edge. Each may have a configuration in which a portion for sandwiching the second mouth part in contact with the first mouth part from the inside thereof is formed.

With such a configuration, when the lid is turned and covered so as to cover the first mouth of the outer container, the second mouth of the inner container accommodated in the outer container is fixed to the first mouth. And the first mouth and the second mouth can be closed by the lid.

  In the beverage container according to the present invention, the outer container may be a metal container, and the inner container may be a soft and flexible synthetic resin container.

  With such a configuration, the outer container can be increased in rigidity and mechanical strength, and can be easily handled such as replacing the inner container.

  Moreover, the container for drinks which concerns on this invention WHEREIN: The said inner container can be set as the structure which has a shape extended-contracted in the direction which crosses an up-down direction.

  With such a configuration, the inner container has a shape that expands and contracts in a direction crossing the vertical direction. Therefore, even if the opening diameter of the first mouth portion of the outer container is small, the inner container having a relatively large capacity can be shrunk. The container can be accommodated in the outer container, and the inner container can be easily replaced. In addition, since the inner container having a shrunk shape can be molded from a synthetic resin, a resin molding machine (such as a mold) for molding the inner container can be downsized.

  Furthermore, in the beverage container according to the present invention, the inner container may have a configuration that expands and contracts in the vertical direction.

  With such a configuration, since the inner container in a contracted state can be formed of synthetic resin, a resin molding machine (such as a mold) for forming the inner container can be reduced in size.

  According to the beverage container of the present invention, it is possible to replace the inner container accommodated in the outer container and filled with the beverage by attaching and detaching the mouth fixing member, so the inner container of the used container is replaced. Thus, it is possible to realize a returnable beverage container that does not need to be cleaned or that can be simply cleaned of the outer container.

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

  The beverage container according to the first embodiment of the present invention is configured as shown in FIGS. In addition, the container for drinks concerning this embodiment is a beer barrel container, FIG. 1 is an external appearance perspective view which shows the external appearance of the beer barrel container, and FIG. 2 shows the structural member of the beer barrel container. FIG. 3 is an exploded perspective view, FIG. 3 is a sectional view showing an internal structure of the beer barrel container, and FIG. 4 is a detailed view of a portion A in FIG.

  1 to 3, the beer barrel container has an outer container 10 and an inner container 20 accommodated in the outer container 10. The outer container 10 is composed of an outer container body 11 having a curved bottom and an open top, and an outer container top 12 having an outer shape of a substantially truncated cone shape. The outer container 10 (the outer container body 11 and the outer container top 12) is a metal container having a thickness of about 1.0 mm formed of, for example, an aluminum alloy. The opening edge portion of the outer container body 11 and the end edge portion of the joining edge portion 122 of the outer container top 12 are joined and fixed by double winding (may be welding), and the outer container body 11 and the outer container top 12 are fixed. And the outer container 10 is configured integrally. At the upper end of the outer container top 12, that is, at the upper end of the outer container 10, an outer opening 121 (first opening) that opens in a circular shape is formed. The inner container 20 is, for example, a soft and flexible synthetic resin container formed of LDPE (low density polyethylene) resin and having a thickness of about 0.4 mm. A portion 201 (second mouth portion) is formed.

  Similar to the outer container 10, the lid 30 is a metal basin made of an aluminum alloy and having a thickness of about 1.0 mm, for example, and covers the center of the disk surrounded by the outer edge 31. The mouth portion 32 (third mouth portion) is provided. A screw thread is formed on the inner peripheral surface that continues from the circular opening of the outer opening 121 of the outer container top 12 described above, and the lid 30 can enter from the circular opening of the outer opening 121 and the outer edge. A thread that meshes with the thread formed on the inner peripheral surface of the outer opening 121 is formed on the outer peripheral surface of 31. The cap 40 can be attached to and removed from the lid opening 32 formed in the lid 30. Moreover, the specific structure of the lid part 32 can be the same as that provided in a known beer barrel container. For example, a base structure that can be attached with a valve for taking out beer can be used.

  When the lid 30 is screwed into the outer opening 121 so as to be fitted from the circular opening, the inner opening 201 of the inner container 20 accommodated in the outer container 10 (the outer container main body 11 and the outer container top 12) becomes the outer container. 10 (outer container top 12) is fixed so as to come into contact with the inner side of the outer mouth part 121, and the outer mouth part 121 and the inner mouth part 201 are sealed by the lid 30. Further, in detail, as shown in FIG. 4 (detailed view of the portion A in FIG. 3), a step portion 31 a in which the tip portion of the inner mouth portion 201 of the inner container 20 is formed on the outer edge portion 31 of the lid body 30. And the inner opening 201 of the inner container 20 are fixed to the outer opening 121 of the outer container top 12. The inner opening 201 of the inner container 20 is fixed to the outer opening 121 of the outer container top 12.

  Thus, the lid 30 has the original function of closing the inner mouth portion 201 of the inner container 20 together with the outer mouth portion 121 of the outer container 10, and the outer mouth portion of the outer container 10. And a function as a mouth fixing member that is fixed to 121.

  An upper bumper 50 is fixed to the upper portion of the outer container body 11 by adhesion or the like so as to cover the outer container top 12. The upper bumper 50 is made of, for example, ABS resin, and handles 51a, 51b, 51c, 51d are formed around the upper bumper 50. Further, similarly to the upper bumper 50, a lower bumper 60 formed of, for example, ABS resin, NBR rubber or the like is fixed to the lower portion of the outer container body 11 by adhesion or the like. The upper bumper 50 and the lower bumper 60 allow the beer barrel containers to be stacked, and the beer barrel containers can be carried by the handles 51a, 51b, 51c, 51d formed on the upper bumper 50.

  In the beer barrel container having such a structure, when the inner container 20 is replaced, the lid 30 is removed from the outer mouth part 121 of the outer container top 12 to remove the outer container top of the inner mouth part 201 of the inner container 12. After releasing the fixing to the mouth part 121, the inner container 20 is pulled out from the outer container 10 through the outer mouth part 121. Thereafter, as shown in FIG. 5, the new inner container 20 is put into the outer container 10 from the outer opening 121 of the outer container top 12 in a contracted state. The lid 30 seals the outer mouth part 121 and the inner mouth part 201 while fixing the inner mouth part 201 of the inner container 20 to the outer mouth part 121 of the outer container top 12.

  Thereafter, as shown in FIG. 6, beer is injected from the lid opening portion 32, and the inner container 20 in the outer container 10 is filled with beer. And the cap 40 is mounted | worn with the lid part 32, and the said beer barrel container (the outer container 10 and the inner container 20) is sealed.

  According to the beer barrel container having such a structure, the inner container 20 can be attached to and detached from the outer container 10. Therefore, by replacing the inner container 20 together with the lid 30, a metal container having a large weight and volume can be used. Returnable use is possible without cleaning an outer container. In this case, the used inner container 20 and lid 30 can be discarded. Since the outer container 10 basically has few parts that directly touch the contents, even when it is cleaned, for example, the use of chemicals can be reduced. It can be reduced. Further, the lid body 30 may be washed and used repeatedly as necessary.

  An inner container 21 as shown in FIG. 7 can be used.

  The inner container 21 is formed of a synthetic resin such as an LDPE resin as well as the inner port portion 211 formed at the upper end portion thereof, as in the example described above. And the crease | fold part 212a, 212b, 212c, 212d is formed in the trunk | drum part of the inner container 21 so that it may extend in an up-down direction. Since each of the fold portions 212a, 212b, 212c, and 212d bends and extends, the inner container 21 expands and contracts in a direction H that crosses the vertical direction as shown in FIG.

  Such an inner container 21 is inserted into the outer container 10 from the outer opening 121 of the outer container top 12 in a state in which the inner container 21 is contracted in a direction H crossing the vertical direction. As in the example described above (see FIGS. 1 to 4), as shown in FIG. 9, the inner mouth portion 211 of the inner container 21 is fixed to the outer mouth portion 121 of the outer container top 12 by the lid 30. The outer mouth part 121 and the inner mouth part 211 are sealed.

  By using such an inner container 21, the same function and effect as the beer barrel container as described above can be obtained, and even if the opening diameter of the outer opening 121 of the outer container top 12 is small, the capacity is relatively large. By shrinking the large inner container 21, it can be accommodated in the outer container 10, and the inner container 21 can be easily replaced. In addition, since the inner container 21 having a contracted shape can be formed of a synthetic resin, a resin molding machine (such as a mold) for forming the inner container 21 can be downsized.

  Furthermore, an inner container 22 as shown in FIG. 10 can be used.

  The inner container 22 is formed of a synthetic resin such as an LDPE resin as well as the inner port 221 formed at the upper end thereof, as in the above-described example. And the crease | fold part 222a, 222b, 222c, 222d is formed in the upper part of the trunk | drum part of the inner container 21, and it extends in the up-down direction, and the bellows 223 is formed in the downward part. Since each of the crease portions 222a, 222b, 222c, and 222d bends or extends, the upper portion of the body portion where these crease portions are formed is similar to the above-described example shown in FIGS. It expands and contracts in a direction that crosses the direction. Further, since the bellows 223 expands and contracts in the vertical direction, the lower part of the body part where the bellows 223 is formed expands and contracts in the vertical direction V as shown in FIG. Note that the diameter of the body portion of the inner container 22 is set to be substantially the same as the diameter of the circular opening of the outer opening 121 formed in the outer container top 12.

  Such an inner container 22 is inserted into the outer container 10 from the outer opening 121 of the outer container top 12, particularly in a state of being contracted in the vertical direction. As in the example described above (see FIGS. 1 to 4), as shown in FIG. 11, the inner opening 221 of the inner container 22 is fixed to the outer opening 121 of the outer container top 12 by the lid 30. The outer opening 121 and the inner opening 221 are sealed.

By using such an inner container 21, the same operation and effect as a beer barrel container similar to those described above can be obtained, and the upper part is shrunk in the vertical direction and the lower part is shrunk in the vertical direction. Since the inner container 22 having a shape can be formed of a synthetic resin, a resin molding machine (such as a mold) for forming the inner container 22 can be downsized.

  Next, a beverage container according to a second embodiment of the present invention will be described.
