Description

Self-locking type environment-friendly carton without adhesive tape

Technical Field

The utility model relates to a carton technical field especially relates to a no sticky tape is from locking-type environmental protection carton.

Background

In present product packaging, adopt carton packing usually more, especially at the very big today of express delivery logistics demand, for convenience carton packing, adopt plastic tape to seal usually. The use of the adhesive tape not only increases the cost of sealing the box, but also causes environmental pollution because the plastic adhesive tape is difficult to be decomposed by soil due to special materials after being used and discarded. If not using the sticky tape joint sealing, the sticky tape carton structure of exempting from and production technology that have existed on the market are too complicated, and manufacturing cost is higher, and artifical inefficiency in the unit interval just can open under the not destroyed prerequisite of carton simultaneously, and factor of safety is low, so in actual popularization, the acceptance among the market in-service use is not high, makes the original intention of the use amount reduction of sticky tape on the carton not reach.

In order to solve the above problems, the chinese patent with application number 201810720525.0, entitled "a tape-free anti-theft carton" discloses the following contents: this exempt from sticky tape theftproof carton realizes the chucking joint sealing through the structure of self, specifically blocks the locking tongue through the locking dog and moves and realize. Although the technical solution of this publication can avoid the use of tape on the top surface of the carton, the bottom surface of the carton disclosed in this patent still requires tape encapsulation.

In order to solve the technical problem that the bottom surface still needs to be packaged by an adhesive tape, a chinese patent with application number 201910773529.X and name "a zero adhesive tape express delivery carton" discloses the following contents: the bottom plate is a whole piece of paperboard without any structural line, and the side plates, the end plates and the cover plate of the carton all use the bottom plate as a center and are assembled and molded after rotating 90 degrees in space. Although the bottom surface of the patent does not need an adhesive tape, the weight of the articles in the box is totally acted on the bottom plate, and the bottom plate is easy to fall off under stress in the process of carrying to cause article damage.
