Concave appliance and its application method

Abstract

The present invention provides two concave utensils which can be identical or different, on their places to be combined the identical concave periphery / convex periphery or groove / tongue or identical locking mechanisms are set. Said two concave utensils can be combined together by means of the above-mentioned identical concave periphery / convex periphery or groove / tongue or identical locking mechanisms, and can be formed into packaging container box.

Description

technical field [0001] The invention relates to a concave utensil, and mainly relates to a container, a packing box (or generally called a box) and a box-type chessboard. Background technique [0002] At present, known public concave utensils, such as various packing boxes, box-type chessboards, basins, barrels, and concaves with walls to form an inner cavity, etc., two identical or different ones are designed and manufactured. All the mating structures of the joint where the mouth of the concave utensil is intended to contact, including the locking mechanism, the turning mechanism, etc., do not have the same concave-convex structure that is stable, dense, and complementary to each other, or do not pass through The turning mechanism, or the connection of the movable wall enclosure corresponds to complementary folding and closing, or is not one-piece manufacturing or simple manufacturing and one-time assembly or simple assembly; even if it is complementary, the application ra...

[0002] At present, known public concave utensils, such as various packing boxes, box-type chessboards, basins, barrels, and concaves with walls to form an inner cavity, etc., two identical or different ones are designed and manufactured. All the mating structures of the joint where the mouth of the concave utensil is intended to contact, including the locking mechanism, the turning mechanism, etc., do not have the same concave-convex structure that is stable, dense, and complementary to each other, or do not pass through The turning mechanism, or the connection of the movable wall enclosure corresponds to complementary folding and closing, or is not one-piece manufacturing or simple manufacturing and one-time assembly or simple assembly; even if it is complementary, the application range is limited and there are many shortcomings, such as joints or no Concave / concave / convex / groove / tenon, locking mechanism, turning mechanism, carrying mechanism and other concave-convex structures that are integral and identical, and corresponding to the opposite direction at the same time, have a single shape, complex components, many molds, cumbersome processes, and materials. Thick weight, overfolding of the end support, or protrusions on the surface of the device that cause space occupation and scratching, or inconvenient matching and color matching; or only rely on shaft support at both ends for folding, which is not firm and dense, and the material tends to be thinner when the size is too large When the plate surface and the connecting (chain) connecting plate parts as the movable wall are also easily deformed and bent, it is inconvenient to use; the function of the box box and the box-type chessboard is monotonous, and it is inconvenient to use both, especially the box-type chessboard lacks perfect packaging due to the above. It is only suitable for use as a box-type chessboard with a single function, and it is not suitable for use as a packaging container for goods in non-chess field and various corresponding non-chess fields while having the function of box-type chessboard. A carrier for the purposeful application of attachments; its production and assembly costs are high and resource utilization is low
