Abstract

A roller assembly includes at least one roller, an L-shaped board and at least one L-shaped fixing member. The L-shaped fixing member is fixed on the L-shaped board; and the roller is fixed and connected on the L-shaped board through the L-shaped fixing member. A package includes a box and the roller assembly. The box contains at least one hole and the roller protrudes from the hole. Further, the package is used as follows. The box is opened and the matter to be packaged is put into the box. Then the roller assembly is placed into the box, and the roller assembly is sandwiched between the box and the matter. Next, the roller(s) is aligned with the hole(s). Subsequently, the box and the matter are compressed to make the roller(s) protrude from the hole(s). Finally, the box are sealed from the bottom surface to complete the package.

First claim

What is claimed is:

1. A package, comprising:
a box comprising a first corner edge and at least one hole formed at or adjacent to the first corner edge of the box; and
a roller assembly removably disposed inside of the box, wherein the roller assembly comprises:
an L-shaped board comprising a first portion, a second portion, and a first edge formed by the first and second portions;
at least one L-shaped fixing member, each of the at least one L-shaped fixing member comprising a third portion, a fourth portion, a second edge formed by the third and fourth portions, a roller bracket and a connecting rod, wherein
the third portion is fixedly connected to the first portion of the L-shaped board;
the fourth portion is fixedly connected to the second portion of the L-shaped board;
the second edge formed by the third and fourth portions is substantially parallel to the first edge formed by the first and second portion of the L-shaped board;
the roller bracket is formed at a side of the third portion opposite to the first portion of the L-shaped board; and
the connecting rod is fixedly connected to or integrally formed with the roller bracket; and

at least one roller, each respective roller in the at least one roller rotatably connected to the connecting rod of a corresponding fixing member in the at least one fixing member,
wherein the roller assembly is configured to be removably disposed inside of a box with the at least one roller protruded out of the box to allow transportation of the box by rolling;

wherein
the first and second portions of the L-shaped board of the roller assembly are disposed between the box and a matter packaged in the box;
the first edge formed by the first and second portion of the L-shaped board of the roller assembly is substantially parallel to the first corner edge of the box; and
the at least one roller of the roller assembly protrudes from the box through the at least one hole formed at or adjacent to the first corner edge of the box.

2. The package of claim 1 , wherein the box comprises a top surface, a plurality of sidewalls, and a bottom surface; the bottom surface is openable, the bottom surface meets the plurality of sidewalls to form a plurality of corner edges; the plurality of corner edges comprises the first corner edge.

3. The package of claim 2 , wherein a handle chamber is arranged on the top surface, and a foldable handle is installed in the handle chamber.

4. The package of claim 3 , wherein the handle chamber comprises a U-shaped groove, and the U-shaped groove is symmetrical with respect to a center line of the top surface.

5. The package of claim 3 , wherein the handle chamber comprises a bar groove, and an end of the bar groove is arranged on a center line of the top surface.

6. A method of making a rollable package, comprising:
obtaining the package of claim 1 ;
opening the box of the package and putting a matter to be packaged into the box;
placing the roller assembly of the package into the box, so that the first and second portions of the L-shaped board of the roller assembly are to be sandwiched between the box and the matter to be packaged upon completion of the rollable package;
aligning the at least one roller of the roller assembly with the at least one hole formed at or adjacent to the first corner edge of the box;
compressing one or more of the box and the matter to be packaged to make the at least one roller of the roller assembly protrude from the at least one hole formed at or adjacent to the first corner edge of the box;
sealing the box to complete the rollable package.

7. The package of claim 1 , wherein a number of the at least one roller is equal to a number of the at least one L-shaped fixing member.

8. The package of claim 1 , wherein for each respective roller in the at least one roller, the connecting rod passes through a center of the respective roller, two ends of the connecting rod are fixed and connected to the roller bracket, and the respective roller rotates around the connecting rod.

9. The package of claim 1 , wherein the at least one L-shaped fixing member is fixed on the L-shaped board by screws, or the at least one L-shaped fixing member is welded on the L-shaped board through solders.

10. The package of claim 1 , wherein the L-shaped board is made of a material selected from the group consisting of plastic, metal and rubber.

11. A package, comprising:
a box comprising:
a top surface;
a plurality of sidewalls;
a bottom surface that is openable;
a plurality of corner edges formed by the bottom surface and the plurality of sidewalls, wherein the plurality of corner edges comprises a first corner edge formed by the bottom surface and a first sidewall in the plurality of sidewalls; and
at least one hole formed at or adjacent to the first corner edge; and

a roller assembly removably disposed inside of the box, wherein the roller assembly comprises:
an L-shaped board configured to be removably disposed inside of the box, the L-shaped board comprising a first portion, a second portion integrally formed with the first portion, and a first edge formed by the first and second portions;
at least one fixing member fixedly connected to the L-shaped board, wherein when the L-shaped board is disposed inside of the box, the at least one fixing member is disposed at or adjacent to the at least one hole of the box; and
at least one roller, each respective roller in the at least one roller rotatably connected to a corresponding fixing member in the at least one fixing member, wherein when the L-shaped board is disposed inside of the box, each respective roller in the at least one roller is protruded outward from the box through a corresponding hole in the at least one holes of the box and rotatable around an axis substantially parallel to the first corner edge in the plurality of corner edges of the box, thereby allowing transportation of the box with the matter packaged in the box by rolling;

wherein when the L-shaped board is disposed inside of the box:
the first portion of the L-shaped board of the roller assembly is disposed between the first side wall in the plurality of sidewalls of the box and a matter packaged in the box;
the second portion of the L-shaped board of the roller assembly is disposed between the bottom surface of the box and the matter packaged in the box;
