Packaging strip

Abstract

A packaging strip comprises a plastic lock bar, each of the upper and lower faces of the plastic lock bar is provided with a plurality of rows of anti-pullback clamp teeth, each row includes two anti-pullback clamp teeth, one end of the plastic lock bar is provided with a lock cylinder, each of the front and rear ends of a lock hole of the lock cylinder is provided with a bolt, each bolt has a unidirectional-insertion reverse-fastening structure; a plastic lock bar receiving space is formed between the front and rows of the bolts. The plastic lock bar and the lock cylinder are formed by singleinjection molding; the production process is simplified; production capacity is improved. The lock bar and the lock cylinder are of double-side anti-pullback structure, top-bottom double safety is achieved by single locking via the lock hole, and pullback of the strip is effectively avoided; the efficient space is reserved between the two rows of the bolts in the lock cylinder, and slight packaging force can be ensured for application of the packaging strip. The packaging strip has the advantages of simple structure, good convenience of use and good durability.

Description

technical field [0001] The invention relates to the technical field of packaging tools for packaging after sorting goods in the express delivery industry, in particular to a sealing strip. Background technique [0002] Sealing strips are widely used in the packaging of goods in major express, express, and logistics industries, and iron pins are aimed at the express packaging industry. At present, there are roughly three types of sealing strips on the market. One is to use stainless steel metal materials to make reverse pull cards. Welding, low production capacity, high cost, low product qualification rate, and the steel sheet contained in it cannot be crushed and reused; the second type is plastic with one-time injection molding and double-safety locks, but there are troubles in use and misuse of sealing single-way locks. The risk of insurance function from the start; the third type uses plastic injection molding to complete the single insurance lock, but there are defects ...

AI Technical Summary

Problems solved by technology

At present, there are roughly three types of sealing strips on the market. One is to use stainless steel metal materials to make anti-pull back cards. After sealing, the metal cards play a role in anti-pull back. Due to the complicated process, including injection molding, assembly, thermal crimping or ultrasonic Welding, low production capacity, high cost, low product qualification rate, and the steel sheet inside cannot be crushed and reused; the second type is plastic one-time injection molding with double safety locks, but there are troubles in use and misoperation of sealing single-way locks. The risk of starting to the insurance effect; the third type uses plastic injection molding to complete the single insurance lock, but there are defects in the use of strong sealing force and high risk of pullback
