Latching device and exempt from adhesive tape rescue bag vanning
Technical field
The utility model relates to a kind of technology of packaging field, specifically a kind of latching device and exempt from adhesive tape rescue bag
Vanning.
Background technique
Packing case is widely used in actual life, and in recent years in particular with the fast development of express delivery industry, packing case makes
Dosage increases severely.Overwhelming majority packing case will use adhesive tape in encapsulation process at present, and adhesive tape has one in process of production
Fixed environmental pollution, it is often more important that adhesive tape is degraded relatively difficult in the environment, certainly will will cause new environmental pollution in this way, together
When during unpacking using sharp instrument unpacking be likely to result in unpacking personnel scratch the problems such as.
At present during using packing case, often there is violence sorting in especially express delivery and logistic industry, and the people that obtains employment
Member or other staff appear in the newspapers situations such as stealing article in case end repeatly, how effectively to guarantee that packing case Neto posts the safety of object,
As many people's concerns.
To solve the above problems, occurring double-sided adhesive packing case scheme on existing market.This kind of packing case is in top lid and bottom
It covers and double-sided adhesive adhesive area is respectively set, tear strip is set in top cover, theft-prevention structure is set in adhesive area, as theft-prevention structure is broken
It is bad then illustrate in packing case that article is stolen or is changed.This kind design still has the deficiency in environmental protection, increased technique and auxiliary material
Also bringing along production efficiency reduces the problems such as rising with product cost, while facing in antitheft and safety Design and once occurring
The theft-prevention structure of adhesive area is damaged to be will be unable to differentiate packing case to be the problem that recipient destroys or destroys when stolen.
Utility model content
The utility model In view of the above shortcomings of the prior art, proposes a kind of latching device and exempts from adhesive tape rescue bag
Vanning can be achieved with safe joint sealing by self structure, do not having to its advantage is that reducing auxiliary material use to greatest extent
In the case of adhesive tape again, it will be able to effectively achieve antitheft effect, improve support and post object safety, can ensure that each side's equity can reach
To the purpose of protection environment.
The utility model is achieved through the following technical solutions:

The utility model relates to one kind to exempt from the vanning of adhesive tape rescue bag, be equipped with:
Cabinet, including bottom plate and around the sidewall paneling of bottom plate;
Case lid is used for closed box, including box cover body and the flange connecting with box cover body;
Latching device as described above, including slot, connecting plate, plate and lock tongue;The slot is arranged on flange or case
On the sidewall paneling to offset in body with flange, the connecting plate is correspondingly arranged on the sidewall paneling to offset in cabinet with flange or flange
Upper, rotatably fold;The plate is rotatably turned down relative to connecting plate;The lock tongue is arranged at left and right sides of plate, is opposite
It rotatably turns down in plate, is pressed when plate is inserted into slot with plate, locked after plate is inserted into slot in nature open configuration
Tight case lid and cabinet.
Preferably, the slot is equipped with arc protection tongue on one side, protects after latching device is inserted into slot plate,
Reduce the size that plate protrudes from slot, avoids latching device from being pulled, further increase the safety of packing case.
Preferably, described to exempt from the vanning of adhesive tape rescue bag using corrugated board integrated molding;
It is further preferred that it is described exempt from adhesive tape rescue bag vanning be correspondingly provided on bottom plate and the sidewall paneling to offset with bottom plate
Latching device can reduce one of gluing process or flat wire nail case process, reduce cost.
Latching device is correspondingly provided with, it can be achieved that without auxiliary material in the two side wall panels of fitting it is highly preferred that crowding around in the cabinet
Joint sealing is more advantageous to environmental protection.
It is described to exempt from the vanning of adhesive tape rescue bag equipped with failure line of unpacking, it takes out to hold in the palm by failure line opening cabinet of unpacking and post
Object improves convenience of unpacking.
Technical effect
Compared with prior art, the utility model can be realized the effective antitheft of packing case by latching device, improve support
Post the safety of object;It could only be stolen by destroying cabinet or latching device, replace to hold in the palm in packing case and post object, and cabinet or lock
The damage of buckle mechanism easily identifies, it is thus possible to ensure each side's equity, support is avoided to post unnecessary caused by the stolen grade of object evade
It disputes over trifles;And adhesive tape is not used, and it economizes on resources, be conducive to environmental protection, additionally it is possible to the efficiency of packing case recycling and reusing is improved, while
Without changing existing carton production technology, process equipment, it is suitable for marketing.
