Title: Packaging box with cleaning function

Description:
BACKGROUND OF THE INVENTION  
       [0001] I. Field of the Invention  
       [0002] This invention relates generally to a packaging box with cleaning function and, more specifically, to a packaging box with cleaning function that can have the optical coating lenses packed directly for supersonic wave cleaning or washing, and drying up to achieve simplified, fast cleaning and packaging.  
       [0003] II. Description of the Prior Art  
       [0004] Heretofore, it is known that in the manufacturing process of the electro-optical coating lenses, after the lens is coated, it has to be placed into a slot (a 3 ) of a clean-up basket (a) (as shown in FIG. 5), then the clean-up basket (a) filled up with lenses (c) is placed into a supersonic wave water tank for cleaning up; after cleaning up, the clean-up basket (a) is taken out to dry up all the lens (c); after drying up all the lenses (c) have to be taken out manually from the clean-up basket (a) and inserted into the slot (b 3 ) with a bottom (b 2 ) of the carrier (b 1 ) of the packaging box (b) (as shown in FIG. 3, FIG. 4), finally cover with a top (b 4 ) to finish the packaging. Based on above description, the most disadvantage is to place the lenses (c) into the clean-up basket (a) and then remove the lenses (c) from the clean-up basket (a) to the carrier (b 1 ) manually, the procedure not only increase and waste manpower but also might cause stains on the surface of those lenses to degrade the quality.  
       [0005] A perspective view of the prior art, as shown in FIG. 5, the clean-up basket (a) consists of a frame (a 1 ) and several sticks (a 2 ) span over the two sides of the frame (a 1 ), on both sides of the stick (a 2 ) has several indentation (a 3 ) in wave shape, every lens (c) is held vertically by two indentation (a 3 ) of two neighboring sticks (a 2 ), several supporting sticks (a 4 ) are on the bottom of the frame (a 1 ) to hold the bottom of the lenses (c). A plurality number of long hole (a 5 ) are on both sides of the frame (a 1 ) to adjust the width of two neighboring sticks (a 2 ) for different size of lenses (c); the stick (a 2 ) passes through the long hole (a 5 ) and is fastened by nut (a 6 ) on both ends of the long hole (a 5 ). The known prior art is very complex and not very convenient to apply, the adjustment of the width of stick (a 2 ) for different size of lenses (c) also influences the process. Certain parts of the traditional clean-up basket (a) are made of metal, after sometimes, they might be oxidized that might causes stains to the lenses (c). The known clean-up basket (a) are also very expensive.  
       SUMMARY OF THE INVENTION  
       [0006] It is therefore a primary object of the present invention to provide a packaging box with cleaning function comprising a carrier in tray shape and a top cover, several slots are on the carrier, several indentations are vertically on both sides of the slot, every corresponding pair of the indentations is to place a optical coating lens, such mechanism can reduce the numbers of optical coating lenses movements to make cleaning, drying up and packaging finished within the same carrier to reduce the overall cost.  
       [0007] It is a further objective of the present invention to provide a packaging box with cleaning function in which reduces the numbers of optical coating lenses movements, such mechanism can avoid the optical coating lenses from staining for better quality.  
       [0008] It is another objective of the present invention to provide a packaging box with cleaning function in which applies no metal material, no oxidation will happen to stain the optical coating lenses, such mechanism can offer better quality products.  
       [0009] It is still a further objective of the present invention to provide a packaging box with cleaning function in which the carrier can be applied as a clean-up basket for a short period of time, to avoid the expensive cost and the width adjustment problems of prior art.

     DESCRIPTION OF THE PREFERRED EMBODIMENT  
     [0016] Referring to FIG. 1 and FIG. 2, the present invention is composed of a carrier  10  in tray shape and a top cover  20 ; several slot  11  are on the carrier  10 , several indentation  12  are vertically on both sides of the slot  11 , every corresponding pair of the indentation  12  is to place a optical coating lens  30 .  
     [0017] Based on above structure, the bottom  11   a  of the slot  11  has a long open  11   b , the bottom  11   a  is inclined downward; a plurality numbers of small hole  14  are on top  13  (or higher location) of the carrier  10 ; the inclined bottom  11   a  are in funnel shape (as shown in FIG. 2) not only easier to drain water but also can hold the optical coating lens  30  in the indentation  12 ; the small hole  14  can exhaust air when the carrier  10  is placed into the water tank but also drain water easier when the carrier  10  is taken out of the water tank.  
     [0018] The optical coating lens  30  are placed vertically into the indentation  12  of the slot  11  while finish plating, the carrier  10  and all the optical coating lens  30  are placed into water tank (not shown in FIG) to clean with supersonic wave or clean water; after cleaning up, all the water will flow along the inclined bottom  11   a  and go out from the long open  11   b ; the top cover  20  is on after all dry up. Such scheme can achieve manpower, manufacturing cost saving and avoid human stains and traditional clean-up basket oxidation stains for better quality.  
     [0019] Referring to FIG. 2, the top  13  of the carrier  10  is inclined (or double inclined) up to keep water from staying; such scheme can achieve faster water flowing.  
     [0020] Referring to FIG. 1, a bottom cover  40  is added to achieve complete dust-free effect.  
     [0021] While a preferred embodiment of the invention has been shown and described in detail, it will be readily understood and appreciated that numerous omissions, changes and additions may be made without departing from the spirit and scope of the invention.
