Description

Cardboard stacking and embedding structure

The present invention relates to a carton stacking and locking structure, in particular to a carton containing fruits, which can be tightly closed without the need for adhesive tape when the two upper cover sheets of the top opening are closed, and when two cartons are stacked up and down, the four uniquely arranged locking and positioning protrusions on the top of the lower carton can be inserted into the four corresponding locking holes on the bottom of the upper carton to form a feature of the upper and lower cartons being firmly buckled and not easily tipped over. It is indeed a unique invention that facilitates stable stacking and can increase economic benefits.

According to Taiwan, which is a production area of various fruits, when packing fruits, the fruit is usually packed into cartons and then the opening is sealed manually with tape to ensure the integrity of the fruit cartons. When there are many cartons containing fruits, workers will stack the cartons upwards. However, in order to prevent the cartons from slipping or tipping over due to stacking too high, which may cause damage to the fruits, there is a height limit, which wastes the use of space. Therefore, how to pack the fruits in a way that saves manpower and does not require additional tape to tightly close the opening of the cartons, and how to facilitate stacking cartons without causing the stacked cartons to slip or tip over and cause damage to the fruits, is a direction that the industry is eager to improve and design.

In view of this, the inventor of this case, based on his many years of research and development experience in related fields, conducted in-depth research on the above-mentioned deficiencies and actively sought solutions based on the above-mentioned needs. After a long period of hard research and multiple tests, he finally completed this invention, which solves the shortcomings of the application and enhances its unprecedented progress and practicality.

Therefore, the main purpose of the present invention is to provide a "carton stacking and locking structure", which is mainly to provide two locking protrusions on each of the two upper cover sheets at the top opening of the carton, and to cooperate with the locking holes on the two lower upper cover sheets, so that the locking protrusions can be locked into the locking holes, so that the top opening of the carton can be tightly sealed without the need for manual additional adhesive tape and not easily opened.

The secondary purpose of the present invention is to provide a "carton stacking and embedding structure", which mainly forms two embedding and positioning convex pieces at 90 degrees upward at the 4th fold line of the edge of the side sheet of the first long paperboard and the 9th fold line of the edge of the side sheet of the second long paperboard on the top end surface of the carton, and forms two embedding holes at the 6th fold line and the 10th fold line symmetrically below the embedding and positioning convex pieces, so that when the cartons of the present invention are stacked up and down, the embedding holes of the upper carton can be inserted into the embedding and positioning convex pieces of the lower carton, thereby achieving the stability of the stacking and preventing the stacked cartons from slipping.
