Description

FIELD OF THE INVENTION

The present invention relates to a package box and particularly to an improved package box for holding a plurality of products of different dimensions.

BACKGROUND OF THE INVENTION

It is a common practice for many vendors to design and prepare different sizes of package boxes to hold finished products of different dimensions in a steady manner. The package boxes have to match the product type and size, such as small electronic elements (transformers, inductor, coils, etc.), medium size electronic elements (network adapter cards, temperature regulators, serial communication conversion modules, etc.), or large electronic elements. Refer to FIG. 1 for a conventional package box for electronic elements. It has only one container 1 designed to match the size of an electronic element to be held. Hence package boxes of different sizes of containers have to be designed to hold different sizes of electronic elements. For vendors having dozens of products, they have to prepare dozens of different package boxes. This is not only costly, but also bad for the environment.

Hence there is a requirement to hold more electronic elements in one package box to reduce usage of package boxes.

One approach is to add a spacer layer in the container to increase the housing space. FIG. 2 shows such an example. A spacer layer 5 is added in a package box 3 to form a partition to hold goods intimately. However, the spacer layer 5 is movably rested on the bottom of the goods held in the box and cannot hold the goods steadily.

SUMMARY OF THE INVENTION

In view of the aforesaid problems, the primary object of the present invention is to provide an improved package box that can hold goods steadily even when subject to shaking or vibration.

In one aspect, the improved package box according to the invention has a plurality of folding spacer layers formed in an integrated manner to hold goods of different sizes.

In another aspect, the improved package goods according to the invention are adaptable to varying product dimensions to overcome the problem of producing one package box for one product.

To achieve the foregoing object, the improved package box according to the invention includes a body, which has two bendable folds on two opposing sides, extended to form a first plate and a second plate. The first plate and the body are coupled to form a first interface, and the first plate and the second plate are coupled to form a second interface. On the first and second interfaces, flanges and corresponding indentations are formed, and containers are provided for holding goods of varying dimensions. The flanges and indentations are paired and coupled with each other such, that the first plate and the body, and the second plate and the first plate can be repeatedly opened to access the goods held in the containers as desired or closed securely to hold the goods steadily.

The body also includes a third plate extended from a bendable fold of one remaining side of the body to form a third interface with the second plate. The second and third plates have respectively a flange and an indentation on the third interface that match each other and a container for holding goods of varying dimensions. The flange and indentation are paired and coupled with each other such, that the third plate and the second plate can be repeatedly opened to access the goods held in the container as desired or closed securely to hold the goods steadily.

In addition, the body further includes a fourth plate extended from a bendable fold of another remaining side of the body to form a fourth interface with the third plate. The third and fourth plates have respectively a flange and an indentation on the fourth interface that match each other to form a container for holding goods of varying dimensions. The flange and indentation are paired and coupled with each other such, that the fourth plate and the third plate are repeatedly opened to access the goods held in the container as desired or closed securely to hold the goods steadily.

The foregoing, as well as additional objects, features and advantages of the invention will be more readily apparent from the following detailed description, which proceeds with reference to the accompanying drawings.

The package box according to the invention is formed in a single shell from a foamed material. It mainly includes a body 7, a first plate 9 extended from one side of the body 7 in an integrated manner, and a second plate 11 extended from the opposite side of the body 7 in an integrated manner.

The body 7 has an indentation 13 on the periphery directing downwards to form a container 15 within the boundary thereof for holding various types of electronic elements. The body 7 has a membrane type bendable fold 17 on one side connecting to the first plate 9, which has a size matching the body 7 and can be flipped to cover the top side of the body 7. The first plate 9 has a flange 19 formed on an interface covering the body 7. The flange 19 matches the shape and depth of the indentation 13, so that the flange 19 can be coupled with the indentation 13 to allow the first plate 9 to be opened or closed as desired.

The first plate 9 further has an indentation 21 formed on the periphery to form at least one container 24 within the boundary thereof for holding various types of goods.

The second plate 11 is connected to another side of the body 7 opposite to the first plate 9 through a bendable fold 23 and has a size matching the first plate 9. Moreover, the second plate 11 has a flange 27 formed on an interface covering the first plate 9. The flange 27 matches the shape and depth of the indentation 21 of the first plate 9 and may be flipped to couple with the indentation 21 to allow the second plate 11 to be opened or closed over the first plate 9 as desired.

Within the boundary of the flange 27 of the second plate 11, a recess 29 may be formed corresponding to the container 24 of the first plate 9 to increase the holding capacity of the container 24.

By means of the construction set forth above, when in use, the first plate 9 is flipped to couple with the body 7 to allow the container 15 formed between the first plate 9 and the body 7 to hold goods of the corresponding size. And the second plate 11 is flipped to couple with the first plate 9 to combine the container 24 and the recess 29 for holding an electronic element of the matching size. The flanges and the indentations can be wedged and coupled securely.

Refer to FIGS. 4A and 4B for another embodiment of the invention. It differs from the one shown in FIGS. 3A and 3B by having an additional plate. Namely, the embodiment shown in FIGS. 3A and 3B has two plates, but the embodiment shown in FIGS. 4A and 4B has three plates.
