The wall 12 is tapered toward a bottom of the wall 12 such that an enclosed area at a top of the wall 12 is greater than an enclosed area at the bottom of the wall 12.

The wall 12 has an abutting edge 13 surroundingly disposed on the top of the wall 12 and outwardly extending from the top of the wall 12. The abutting edge 13 is in a rectangular annular shape to form a sealing collar 14 upwardly extending from the abutting edge 13, and has four abutting surfaces 132 and four curved corners 133. Each abutting surface 132 is disposed between adjacent two of the corners 133 of the abutting edge 13. The sealing collar 14 is located along the abutting edge 13 adjacent to the abutting surfaces 132 such that the sealing collar 14 is formed as a rectangular annular shape. Each corner 133 of the abutting edge 13 has an insert portion 131 formed on the corner 133.

Each insert portion 131 has a linking groove 134, an upper hole 135, a lower hole 136, an elongated positioning hole 1352, and an upper enlarged hole 1351. The linking groove 134 is defined in the insert portion 131. The upper hole 135 is defined through a top of the insert portion 131 and an inner surface of the linking groove 134. The lower hole 136 is defined through a bottom of the insert portion 131, aligned to the upper hole 135, and communicates with the linking groove 134. The elongated positioning hole 1352 is defined through the insert portion 131, crosses and communicates with the upper hole 135. The upper enlarged hole 1351 is defined in the inner surface of the linking groove 134, located adjacent to the upper hole 135, and communicates the upper hole 135 with the linking groove 134 such that an inner diameter of the upper enlarged hole 1351 is equal to or greater than a maximum diameter of the upper hole 135.

Each of the upper holes 135 and the aligned lower holes 136 is formed as an olivary shape. With reference to FIG. 3A, the upper hole 135 has a major axis imaginatively extending to meet any one of the two adjacent abutting surfaces 132 at a forty-five-degree angle, and the lower hole 136 has a major axis imaginatively extending to meet any one of the two adjacent abutting surfaces 132 at a forty-five-degree angle. With reference to FIG. 3B, each positioning hole 1352 is formed as an olivary shape, which is same as that of the upper hole 135, such that the positioning hole 1352 has a major axis imaginatively meeting the major axis of the crossed upper hole 135 at a forty-five-degree angle. The cap 21 is mounted on a top of the casing 10. The cap 21 is in a rectangular shape and has four depressions 211, an inner collar 212, and a sealing slot 213. The four depressions 211 are respectively defined in four corners of the cap 21. Each depression 211 has a middle part inwardly indented. The inner collar 212 downwardly extends from a bottom of the cap 21 and surrounds the bottom of the cap 21. The sealing slot 213 is defined between the inner collar 212 and an inner bottom surface for tightly receiving the sealing collar 14 of the casing 10. The four depressions 211 have four buckling portions 22 respectively outwardly extending from bottoms of the depressions 211 for corresponding respectively to the four insert portions 131 of the abutting edge 13. Each buckling portion 22 is a flat plate and has an outer surface aligned with an outer surface of a corresponding insert portion 131.

Each buckling portion 22 has a top hole 221, two buckling seats, and two slopes 231. The top hole 221 is defined through the buckling portion 22. The two buckling seats 23 are respectively formed on two sides of the top hole 221, and respectively located adjacent to two ends of a minor axis of the top hole 221 such that the two buckling seats 23 face to each other. Each buckling seat 23 protrudes from the buckling portion 22 such that the adjacent two slopes 231 are inclined from the buckling seat 23 toward the buckling portion 22. The two slopes 231 are respectively formed on two ends of each of the buckling seats 23. Each top hole 221 corresponds to and aligns with the upper hole 135 of a corresponding insert portion 131 and has an olivary shape corresponding to that of the aligned upper hole 135. A width and a length of each of the top holes 221 are respectively greater than those of each of the upper holes 135. Each top hole 221 has a rounded top enlarged hole 2211 and two auxiliary holes 2212. The rounded top enlarged hole 2211 is defined in a bottom of the cap 21, and aligns to and communicates with the top hole 221. The two auxiliary holes 2212 are defined through the buckling portion 22, are respectively located on two sides of the top hole 221, and communicate with the top enlarged hole 2211. Each of the auxiliary holes 2212 is tapered toward an outer end of the auxiliary hole 2212.

The at least one linkage disc 30 is partially inserted respectively into at least one of the linking grooves 134. Each linkage disc 30 has a thickness being equal to a width of the linking groove 134, a square central orifice 31 axially defined through a center of the linkage disc 30, and four connecting orifices 32 longitudinally defined through the linkage disc 30 and arranged around the central orifice 31. Each connecting orifice 32 has an olivary shape corresponding to that of each of the upper holes 135 for selectively communicating with the upper hole 135 and the lower hole 136 of one of the insert portions 131. With reference to FIG. 3C, two major axes of adjacent two of the connecting orifices 32 imaginatively extend and are perpendicular to each other.

Each one of the at least one buckling bolt 40 is inserted into the top hole 221 of one of the buckling portions 22, the upper hole 135 aligning to the top hole 221, the connecting orifice 32 of one of the at least one linkage disc 30 aligning to the upper hole 221, and the lower hole 136 aligning to the upper hole 221 for respectively locking one of the at least one linkage disc 30. Each buckling bolt 40 has a shank 41, an elongated knob 42, an elongated bottom blocker 43, an elongated middle blocker 44, and an elongated upper blocker 45.

The knob 42 is disposed on a top of the buckling bolt 40. The knob 42 has two ends radially extending from the shank 41 toward two opposite directions to form an olivary shape being same as that of each top hole 221 for buckling the knob 42 on the two buckling seats 23 of each of the buckling portions 22. The knob 42 extends along a direction being perpendicular to an axis of the shank 41. One of the two ends of the knob 42 is provided for selectively buckling on the middle part of an adjacent depression 211.

The bottom blocker 43 is disposed on a bottom of the buckling bolt 40. The bottom blocker 43 has two ends radially extending from the shank 41 toward two opposite directions and has an olivary shape being same as that of each top hole 221, such that a major axis of the bottom blocker 43 and that of the knob 41 imaginatively meet at a 45-degree angle in a longitudinal direction of the shank 41 for buckling a bottom surface of a corresponding insert portion 131.

The middle blocker 44 is disposed between the bottom blocker 43 and the knob 42. The middle blocker 44 has two ends radially extending from the shank 41 toward two opposite directions and has an olivary shape being same as that of each upper hole 135 to be received in a corresponding upper enlarged hole 1351 for buckling an inner top surface of the upper enlarged hole 1351.

The upper blocker 45 is disposed between the knob 42 and the middle blocker 44. With reference to FIG. 6, the upper blocker 45 is positioned adjacent to the knob 42, has two ends radially extending from the shank 41 toward two opposite directions, and has an olivary shape to fit with the two auxiliary holes 2212 of the corresponding buckling portion 22 such that the upper blocker 45 has a major axis defined in the upper blocker 45, imaginatively meeting the major axis of the knob 42 at a forty-five-degree angle in a longitudinal direction of the shank 41, and imaginatively meeting the major axis of the middle blocker 44 at a forty-five-degree angle in a longitudinal direction of the shank 41 for buckling with an inner top surface of the top enlarged hole 2211.

Preferably, the two buckling seats 23 can be omitted, such that the knob 42 of the at least one buckling bolt 40 is downwardly buckled on a top surface of the buckling portion 22 which is located on two sides of the corresponding top hole 221. When the knob 42 with the corresponding buckling bolt 40 are rotated at ninety degrees, the knob 42 is able to align with the corresponding top hole 221 such that the bottom of the knob 42 falls into the top hole 221.

With reference to FIG. 5, the casing 10 is hollow and the sealing slot 213 of the cap 21 is elastically engaged with the sealing collar 14 of the casing 10 such that the casing 10 is sealed to prevent air-leakage. The container of the present invention is able to receive food or clothes for moisture-proof or preservation purposes. Furthermore, the container of the present invention is floatable and is provided for survival during flood shortage or tsunami or any other disaster.

Multiple containers of the present invention can be assembled to form a floating platform. With reference to FIG. 7, four containers of the present invention are assembled. The abutting surfaces 132 of the containers are abutted against each other and the linkage disc 30 is positioned in a middle of the four containers. Four buckling bolts 40 are inserted into the linkage disc 30 for combining the four casings 10 and four caps 21 to form a survival floating platform.

With reference to FIGS. 8 to 9, multiple containers of the present invention can be assembled to form a bigger sized platform or a swimming pool.

With reference to FIGS. 10 to 12, originally, the knob 42 is buckled on the middle part of the depression 211 to prevent the knob 42 from detaching accidentally. When the cap 21 is unsealed, the knob 42 of the buckling bolt 40 needs to be applied with an external force and rotated at ninety degrees. The knob 42 is aligned with the top hole 221 but the upper blocker 45 is not aligned with the two auxiliary holes 2212, such that the buckling bolt 40 cannot be pulled out but the cap 21 is able to be detached.

The bottom blocker 43 and the middle blocker 44 of the buckling bolt 40 are both buckled with the insert portion 131. Even if one of the bottom blocker 43 or the middle blocker 44 is broken, the buckling bolt 40 will not be detached from the insert portion 131. The upper blocker 45 of the buckling bolt 40 is received in the positioning hole 1352 for positioning the buckling bolt 40.

The bottom blocker 43 and the middle blocker 44 of the buckling bolt 40 are not aligned with the lower hole 136 and the upper hole 135 during unsealing of the cap 21. The buckling bolt 40 is kept buckling with the insert portion 131. Therefore, the cap 21 can be detached without influencing the buckling bolt 40 to maintain a connection between containers.

With reference to FIG. 13, the container of the present invention is provided for receiving soil for plant-cultivation. The container of the present invention can also be perpendicularly utilized for storing books or tools, functioning as a bookcase or a tool cabinet.

With reference to FIG. 14, the containers can be stacked upon each other. The abutting edge 13 of the casing 10 abuts against the abutting edge 13 of another casing 10 such that a space is defined between the casing 10 and a bottom of another casing 10 for receiving the linkage disc 30 and the buckling bolt 40 for good storage.

Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
