For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] In the existing packaging technology field, there are problems such as the need to destroy part of the packaging material when taking out small-volume items, the small-volume items in the package may be touched when taking out, and the destroyed packaging material may remain in the package. Therefore, the present invention provides an easy-to-pull packaging board 100 that can be torn cleanly by hand at one time, which can avoid touching the items when tearing to take out the items, and no packaging material remains. In addition, the present invention also provides a method for preparing the easy-to-pull packaging board 100.

[0033] like Figures 1 to 5 As shown, the specific structure of the easy-to-pull packaging board 100 and its specific preparation process according to a preferred embodiment of the present invention are explained.

[0034] like Figures 1 to 5 As shown, the easy-to-pull packaging board 100 includes a bottom plate 10 and a cover plate 20, wherein the bottom plate 10 is formed with a plurality of accommodating pits 11 at intervals for accommodating articles; the cover plate 20 is formed by a sealing film 21 and an easy-to-pull layer 22, the cover plate 20 and the bottom plate 10 are sealed and connected, and the cover plate 20 is preset with a plurality of easy-to-pull pieces 23 at positions corresponding to the accommodating pits 11 by means of dot breaks or half-cut indentations, the easy-to-pull pieces 23 are formed with a picking groove 231 and at least one folding mark 232 by means of dot breaks or half-cut indentations, wherein the picking groove 231 is formed in the easy-to-pull layer 22 so that the easy-to-pull piece 23 can be pulled and torn, and the folding mark 232 is arranged on the pulling path of the easy-to-pull piece 23, and is used for folding the easy-to-pull piece 23 along the folding mark 232 when the easy-to-pull piece 23 is pulled and subjected to force through the picking groove 231, so as to prevent the easy-to-pull piece 23 from falling into the accommodating pit 11.

[0035] It can be understood that the cover plate 20 forms a dotted line or a half-cut indentation by dotted or half-cut indentation, thereby forming the easy-to-pull piece 23, that is, the easy-to-pull piece 23 has an easy-to-tear edge 233, and the easy-to-tear edge 233 is a dotted line or a half-cut indentation, so that when the easy-to-pull piece 23 is pulled through the groove 231, the easy-to-pull piece 23 can be completely torn along the easy-to-tear edge 233, that is, the easy-to-pull piece 23 can be completely torn at one time. Therefore, the present invention provides an easy-to-pull packaging plate 100 with a simple structure and convenient tearing, which can facilitate actual use by users.

[0036] Optionally, the shape of the easy-to-pull-out piece 23 is circular, elliptical or polygonal, wherein the shape of the easy-to-pull-out piece 23 is specifically set according to the shape of the receiving pit 11, that is, the shape of the receiving pit 11 can be one or more of circular, elliptical and polygonal, that is, the easy-to-pull-out packaging board 100 can be simultaneously provided with the receiving pits 11 and the easy-to-pull-out piece 23 of various shapes to meet the packaging requirements of different products, and the number, shape and size of the receiving pits 11 can be specifically set according to the number, shape and size of the items to be packaged, that is, the present invention does not limit the number, shape and size of the easy-to-pull-out piece 23 and the receiving pits 11.

[0037] Moreover, the easy-to-pull member 23 is provided with the folding mark 232. When the easy-to-pull member 23 is pulled, the easy-to-pull member 23 is subjected to force and naturally folded along the folding mark 232. Figure 4 and Figure 5 As shown, the easy-to-pull piece 23 is folded in a direction away from the receiving pit 11, so as to prevent the easy-to-pull piece 23 from falling into the receiving pit 11 during the pulling process, and also prevent the user's hands from contacting the items in the receiving pit 11, ensuring that the items are clean and hygienic. In addition, when the easy-to-pull piece 23 is folded in half, it can be easily held by the user with two fingers, so as to facilitate the tearing of the easy-to-pull piece 23.

[0038] It should be understood that the easy-to-pull packaging board 100 of the present invention may include a plurality of parallel folding marks 232 , and the present invention does not impose any limitation on the number of the folding marks 232 .

[0039] Preferably, the folding mark 232 is arranged in the middle of the easy-to-pull piece 23 , so that the easy-to-pull piece 23 can be folded along a pre-designed pulling path, thereby facilitating the quick pulling and tearing of the easy-to-pull piece 23 .

[0040] It is worth mentioning that the shape of the picking groove 231 is crescent-shaped or U-shaped, which conforms to the ergonomic design and can facilitate the user to open the easy-to-pick-out piece 23 according to the designed easy-to-tear path with bare hands at one time. In other words, the easy-to-pick-out piece 23 does not need to be torn with the help of other auxiliary tools, nor does it need to be torn open with both hands as in the prior art. Therefore, the easy-to-pick-out packaging board 100 of the present invention can not only facilitate the picking of items, but also prevent the items from contacting with hands and being squeezed and damaged.

[0041] In particular, the groove 231 of the easy-to-pull piece 23 is only formed in the easy-to-pull layer 22, that is, the portion of the sealing film 21 corresponding to the groove 231 is retained, that is, when the groove 231 is formed, the sealing film 21 will not be damaged, which is conducive to ensuring the sealing of the connection between the cover plate 20 and the bottom plate 10 when the cover plate 20 is sealed and connected with the bottom plate 10 via the sealing film 21. In addition, since the sealing film 21 is relatively thin, when the user pulls out the groove 231, the sealing film 21 is torn by force and torn away together with the easy-to-pull piece 23, so that the packaging material can be prevented from falling into the receiving pit 11.

[0042] In other words, the sealing performance of the position of the groove 231 corresponding to the receiving pit 11 is maintained by the sealing film 21 to ensure the overall sealing performance of the easy-to-pull packaging board 100 .

[0043] It is worth mentioning that the cover plate 20 forms a sealed connection structure with the bottom plate 10 through the sealing film 21. Specifically, the sealing film 21 of the cover plate 20 forms a sealed connection structure with the bottom plate 10 by heat sealing or self-adhesive cold sealing.

[0044] In addition, it is worth mentioning that the sealing film 21 can be made of aluminum-plastic film. The sealed cover plate 20 is formed by covering and compounding the aluminum-plastic film on the easy-to-pull layer 22, and then the cover plate 20 is sealed and connected to the bottom plate 10 to form the easy-to-pull packaging plate 100.

[0045] It can be understood that the cover plate 20 is pre-set with a plurality of the easy-to-pull parts 23 by means of dot breaks or half-cut indentations, that is, the cover plate 20 is sealed with the easy-to-pull layer 22 through the sealing film 21 in advance, and then forms a sealed connection with the base plate 10, thereby forming the easy-to-pull packaging board 100, so as to facilitate the production of the easy-to-pull packaging board 100.

[0046] It should be understood that the easy-to-pull packaging plate 100 of the present invention is suitable for small-volume items such as medicines or foods, and the present invention does not limit the application of the easy-to-pull packaging plate 100.

[0047] It is worth mentioning that the bottom plate 10 is a PVC plate, and the easy-to-pull layer 22 of the cover plate 20 is a cardboard or a PVC plate. Preferably, in this preferred embodiment of the present invention, the easy-to-pull layer 22 is cardboard, that is, the cover plate 20 is formed by a composite of cardboard and aluminum-plastic film. In the actual application of the easy-to-pull packaging plate 100, the top of the cover plate 20 can be printed with product information and / or product usage prompt information. For example, when the easy-to-pull packaging plate 100 is used as a medicine packaging plate, the easy-to-pull part 23 of the cover plate 20 can be printed with the type and quantity of medicine and the date of consumption of the medicine to remind the user of the time to take the medicine, and the medicine can be classified and quantified through different containing pits 11, which is convenient for users to use.

[0048] It is understandable that the present invention further provides a method for preparing the easy-to-pull packaging board 100, comprising the steps of:

[0049] A. forming a bottom plate 10 by means of a mold, and forming a plurality of receiving pits 11 on the bottom plate 10 for receiving articles;

[0050] B. Compounding the sealing film 21 and the easy-to-pull layer 22 to form a cover plate 20;

[0051] C. Pre-forming a plurality of easy-to-pull pieces 23 corresponding to the receiving pits 11 on the cover plate 20 by means of dot breaks or half cuts, and pre-forming a pull groove 231 on the easy-to-pull piece 23 by means of dot breaks or half cuts, and pre-forming at least one folding mark 232 on the path where the easy-to-pull piece 23 is pulled through the pull groove 231; and

[0052] D. The cover plate 20 and the bottom plate 10 are sealed and connected to form the easy-to-pull packaging plate 100.

[0053] It should be understood that, in the actual preparation process, the processing of the cover plate 20 and the base plate 10 is performed independently, so the step A and the step B and the step C can be steps performed in parallel, that is, in the actual processing, the step B and the step C can be performed sequentially while the step A is being performed, that is, the present invention does not limit the execution order of the step A, the step B and the step C.

[0054] In addition, in the actual processing, the step between step A and step D further includes placing the article in the corresponding receiving pit 11. That is, the easy-to-pull packaging board 100 of the present invention is first loaded with articles and then the cover board 20 and the bottom board 10 are packaged.

[0055] It is worth mentioning that in step C, the shape of the easy-to-pull-out piece 23 formed is circular, elliptical or polygonal, and the easy-to-pull-out piece 23 has an easy-to-tear edge 233, and the easy-to-tear edge 233 is a dotted line or a half-cut indentation, and the shape of the formed picking groove 231 is crescent-shaped or U-shaped.

[0056] In addition, it is worth mentioning that in step C, the folding mark 232 is arranged in the middle of the easy-to-pull piece 23 so that the easy-to-pull piece 23 can be folded along a pre-designed pulling path, thereby facilitating the quick pulling and tearing of the easy-to-pull piece 23.
