## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a packaging and display box for a circular product, and more particularly to a box for packing and displaying circular products.
2. Description of the Prior Art
Usually, different structures should be used when packaging, transporting, and displaying different products. Each of the conventional packaging box, transportation box and display box only has a single function, the operation for the conventional box is described as follows:
When packaging products, the user will put the products in arrays into a paper packaging box and seal it, making it convenient for storage.
When stacking and transporting the packaging box, the products in the packaging box is very heavy, plus the paper box doesn't have enough supporting strength, usually, the user can't stack several boxes together and transport them directly. Therefore, it is necessary to make shelves on the truck, and the shelves have to be transported, along with the products, to the buyer, the shopping mall, etc. The buyer or the shopping also has to arrange storage shelves in their storage space, such that a great number of packaging boxes can be stored. Furthermore, after the packaging boxes are removed from the storage shelves, the shelves will still take up a lot of space.
When displaying the products in a shopping mall, the user has to put the products on the display shelf one by one, and has to rearrange (an empty space will appear after the consumer takes away the outermost products) the products on the shelves, it is not beauty and is inconvenient for the user to take the products and for the seller to count the products.
Therefore, each of the conventional packaging box, the display shelf or the storage shelf only has a single function, it is impossible to utilize the space effectively and reduce the cost. Thereby, how to make a multifunctional box that can replace the packaging box, the display shelf and the storage shelf, is the chief problem the R&D personnel and the manufacturer want to solve.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a packaging and display box for a circular product.
In the lateral sides of the box body of the present invention are defined with a plurality of observing holes for enabling the user to clearly recognizing the products stored in the box body. The output hole and the input hole can be used to bring the display function of the box body into full play. At the corners of the box body are arranged supporting members for improving the carrying capacity and structural strength of the box body. The present invention can allow the packaging and display boxes to be stacked or transported directly, reducing the necessary storage space of many shops.
Another importance objective of the present invention is to provide a display box.
By using the slant sliding board inside the box body and the guideways of the guiding board, the present invention can enable the circular products to slide automatically to the output hole, and the circular products will be separated clearly and arranged in arrays, thus saving the time for tidying up. After the first circular product is taken away by the consumer, the next circular product following the first circular product will slide to the forefront of the output hole automatically, so that the consumer can fetch it conveniently without the risk of knocking over the neighboring products.
