Description

Easily folding theftproof packing box

Technical Field

The utility model relates to a packing box especially relates to an easy folding theftproof packing box.

Background

Present theftproof packing box sets up the zip fastener structure at the box top usually, tears the zip fastener when unpacking and can accomplish the operation of unpacking, and the destroyed tear strip also can play theftproof warning effect after the unpacking.

However, the packaging box still has some defects at present, such as: the top cover of the packing box usually comprises at least one outer cover and a pair of inner covers, 3-4 covers are required to be respectively folded and covered in sequence during folding and forming, and the packing workload is large.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that an easily fold theftproof packing box is provided, can be better compensate the not enough of prior art, folding convenient lower, easy rapid prototyping under the prerequisite of guaranteeing the theftproof function.

The utility model discloses a realize through following technical scheme:

easy folding theftproof packing box connects preceding curb plate, left side board, posterior lateral plate and the right side board as an organic whole including in order to and connect at the top cap at curb plate top, connect the bottom in the curb plate bottom, its characterized in that:

the top cover comprises an outer cover and a pair of inner covers arranged on the left side and the right side of the outer cover;

the outer cover can hermetically cover the top opening of the packing box and is provided with an outer cover edge which can be turned over downwards and covers the outer side of the front side plate; two tearing lines are punched on the outer cover edge, a tearing strip capable of tearing the cover opening of the packing box is formed in the area between the tearing lines, and an adhesive layer capable of fixing the outer cover edge and the front side plate together is arranged on the end part of the outer cover edge and/or the front side plate;

every inner cup is connected with the enclosing cover towards one side of enclosing cover, and the junction is equipped with first fold line, and two inner cup bottoms are connected with left side board, right side board respectively, and the junction is equipped with the second fold line, and the first fold line and the second fold line of every inner cup are crossing, and the third fold line is stretched out towards the one side slant relative with the second fold line to crossing, and the third fold line divides the inner cup into the last inner cup that can overlap from top to bottom after the infolding and lower inner cup.

During folding, earlier with preceding curb plate, the left side board, posterior lateral plate and right side board fold into the box in order, then the third folding line of aiming at two inner cups is controlled hard relatively towards the box inboard, first folding line this moment, second folding line and third folding line infolding, the inner cup intubate makes and covers in the range upon range of inner cup is covered down, the lid fits the packing box top, the enclosing cover turns over down along its folding line between and the posterior lateral plate, the lid fits the packing box top, the folding and the lid of three top apron are accomplished simultaneously in an action and close the operation, only need to utilize the viscose layer with outer cover marginal tip and preceding curb plate at last to glue the jail, can accomplish the packing operation.

In addition, after this packing box fold forming, go up the inner cup and range upon range of in covering down, the double before folding inner cup thickness increase is not folding, and the thickening inner cup has played the effect of strengthening whole box intensity.

Furthermore, the inner cover is as wide as the left side plate and the right side plate, so that the left side and the right side of the top of the box body can be better sealed.

Furthermore, the width of the inner cover after being folded inwards is less than or equal to half of the width of the outer cover. Avoid inner cup folding behind the shaping mutual interference, lead to box top unevenness.

Further, the included angles between the third folding line and the first folding line and between the third folding line and the second folding line 602 are both 45 °. After folding, the inner cover does not have the part exposed outside the box body, the sealing performance is good, and the appearance is more attractive.

Furthermore, the exposed edge of the inner cover is a right-angle edge, a bevel edge, an arc edge or other shapes which are convenient to process and fold.

Furthermore, at least one end of the tearing strip is provided with a tearing head which is internally contracted inside the notch on the outer cover edge, so that the tearing length is effectively reduced on the premise of not influencing the sealed package of the packing box, and the labor is saved during tearing; one end of the tearing head is large, the other end of the tearing head is small, the small end of the tearing head is connected with the tearing strip, the width of the large end is larger than that of the small end, the structure of the large end and the small end ensures that enough finger contact surfaces and easy force are generated during tearing, and meanwhile, the tearing force is prevented from being wasted due to the fact that the tearing strip is too wide, and the tearing head is prevented from being damaged; the breach is the tubaeform of macrostoma outwards, and the breach is passed through the tool line with tearing first both sides and is torn the groove disconnection with the profit, and the groove notch orientation of tearing the groove of profit keeps unanimous with place breach opening direction, and the wide end of the tank bottom that tears the groove of profit is less than the notch width, and the tank bottom is the acute angle tank bottom, and the structure in tubaeform tool line or acute angle profit tear the groove plays the guide effect hard to tearing when tearing and pulling, and once tearing to the end, it is more laborsaving to tear.

Furthermore, the width of the tearing strip is the same as that of the root of the small end of the tearing head, so that the tearing force is applied and the tearing is avoided.

And furthermore, a tearing reinforcing belt is fixedly communicated with the tearing strip and the tearing head along the length direction, so that the tearing strip is prevented from being broken midway.

Still further, the viscose layer coats and is stamped the release layer that can be torn down. From the viscidity that the type layer is used for protecting viscose layer, also avoid packing in-process viscose layer to glue other article simultaneously, finish the back at the packing, tear from the type layer, the packing can be accomplished to the lid closing enclosing cover, convenient and fast. The release layer can be release paper, a plastic release sheet, a plastic release film or other release structures which are easy to tear and are not easy to adhere to the adhesive layer.

And furthermore, at least one part of the outer edge of the release layer is exposed outside the adhesive layer to form an extended easy-tearing section, so that the isolation layer can be torn off from the adhesive layer quickly.

The beneficial effects of the utility model reside in that:

1. the folding and covering operations of the three top cover plates are completed simultaneously by one folding action, and the box body is easy to rapidly form during packaging;

2. the thickness of the inner cover is doubled after the inner cover is folded and formed, so that the overall strength of the box body is enhanced, and the box body is resistant to compression and falling;

3. under the same box body size, the tearing length of the tearing strip is relatively short, and the tearing is labor-saving;

4. the easy-tearing groove at the bottom of the horn-shaped knife line or the acute-angle groove is convenient for tearing the head of the tearing strip, and the box can be dismounted in a time-saving and labor-saving manner after the easy-tearing groove is torn to the bottom;

5. the big one end of tearing the pull head one end is little, guarantees to tear occasionally sufficient finger contact surface and easily exerts oneself, avoids simultaneously tearing the too wide tearing of drawing strip and leads to tearing strenuously, prevents that the tear from tearing the pull head.
