Description

Reusable self-sealing carton

Technical Field

The utility model relates to a carton technical field, concretely relates to repeatedly usable proclaims oneself carton.

Background

Traditional carton, as shown in fig. 1, connect preceding shrouding 1 on the preceding boxboard 3 of box, connect back shrouding 2 on the back boxboard, connect left shrouding on the left boxboard, connect right shrouding on the right boxboard, its upper shed seals to cover in the upper portion of left and right shrouding through preceding shrouding 1, 2 upsets of back shrouding, then glues the box sealing area (not shown in the figure) and realizes. The carton is at the in-process that recycles, takes place the relapse bonding of joint sealing area, tears to go, can cause the damage of preceding, back shrouding 2, influences the outward appearance quality of carton. In addition, the problem that the carton can not be packaged can be caused when the carton sealing belt is not provided.

Among the prior art, the hook face and the hair face of the magic tape are respectively arranged between the relative end faces of the front and the rear sealing plates and the left and the right sealing plates (under the packaging state of the carton), the self-sealing of the carton is realized by using the magic tape, and meanwhile, the magic tape can avoid the damage of the front and the rear sealing plates in the repeated packaging process, thereby ensuring the appearance quality of the carton. But can produce the clearance between preceding, back shrouding and the left and right shrouding, influence the encapsulation effect of carton.

From the sealing film on the sealing carton through preceding shrouding and the anchor coat on the shrouding bonds with the back shrouding, realizes the encapsulation of carton, and simultaneously, the adhesive linkage and the anchor coat of sealing film downside can bond repeatedly, so the carton is recycling, the in-process of encapsulation, preceding, back shrouding can not damage, but the adhesion stress of this structure is compared in the adhesion stress between sealing area and shrouding will be little.

To this end, we propose a reusable self-sealing carton.

Detailed Description

To make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the attached drawings in the embodiments of the present invention are combined to clearly and completely describe the technical solution in the embodiments of the present invention, and obviously, the described embodiments are part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Example 1

Referring to the attached drawings 2-4, the reusable self-sealing carton comprises a carton body, wherein the carton body is formed by sequentially connecting and enclosing a front carton board, a left carton board, a rear carton board and a right carton board, the front carton board is connected with a front sealing plate 1, the rear carton board is connected with a rear sealing plate 2, the left carton board is connected with a left sealing plate, and the right carton board is connected with a right sealing plate;

the upper surface of the front sealing plate 1 is provided with a front gap extending from top to bottom along the thickness direction, the bottom of the front gap is bonded with a packaging film 6, the packaging film 6 extends backwards through the edge of the front sealing plate 1, and the packaging film 6 comprises an isolation layer 6b and a bonding layer 6a arranged from top to bottom;

the upper surface of the rear sealing plate 2 is provided with a rear notch extending from top to bottom along the thickness direction, the bottom of the rear notch is provided with a bonding layer, the upper part of the rear notch is provided with a protective film 4, the protective film 4 extends forwards through the edge of the rear sealing plate 2, a clamping groove is formed between the protective film 4 and the bonding layer, the upper surface of the bonding layer is smooth, the opening of the packaging film is facilitated, and meanwhile, a silicon oil layer can be locally arranged on the upper surface of the bonding layer, so that the opening of the packaging film is further facilitated;

the front end of packaging film 6 can stretch into and press from both sides the dress inslot, and adhesive linkage 6a and anchor coat laminating, adhesion, protective film 4 and the laminating of isolation layer 6b, protective film 4 through isolation layer 6b after extend forward and with the laminating of the upper surface of preceding shrouding 1, the front end of protective film 4 contacts with preceding shrouding 1 promptly, difficult actuation, can avoid the encapsulation to be difficult to punch the card after protective film 4 and the actuation of isolation layer 6 b.

When encapsulating the box upper shed, will turn over left and right shrouding downwards to the horizontal state that fig. 3 shows earlier, secondly cover the upper portion of left and right shrouding with the upset of back shrouding 2, then upwards lift protective film 4, cover the upper portion of left and right shrouding with the upset of preceding shrouding 1 again, simultaneously, the straight and binding course laminating of rear end of encapsulating film 6, close protective film 4 at last and laminate with isolation layer 6b, can realize the encapsulation of box upper shed.

The depth of the front gap and the depth of the clamping groove are equal to the thickness of the packaging film 6, the sum of the depth of the clamping groove and the thickness of the binding layer is equal to the depth of the back gap, and the lengths of the front gap, the back gap, the protective film 4, the packaging film 6, the binding layer are equal to the lengths of the front sealing plate 1 and the back sealing plate 2. Through the control of each layer thickness, each breach, the groove degree of depth, ensure the encapsulation back, protective film, anchor coat respectively with the laminating of encapsulation membrane, preceding, back shrouding respectively with left and right shrouding laminating, further improve the sealed effect of encapsulation.

In the figure, 5 is a left closing plate connected to the upper end of the left box plate of the box body.

In addition, the bottom of the case body directly contacts with the bottom surface, so that the self-locking bottom structure disclosed in utility model patent with publication number CN207497128U can be adopted.

Example 2

Example 2 differs from example 1, with reference to fig. 5, only in that: both ends around the left boxboard of box, both ends around the right boxboard set up locking band 8 respectively, and the upper end of locking band 8 is connected with the hair side that the magic was pasted, and the upper surface of preceding shrouding, back shrouding is connected with the hook face that the magic was pasted, and locking band 8 passes through the magic with preceding shrouding, back shrouding and pastes the connection, tighten the back, can further improve the reliability of overall structure encapsulation. The locking band 8 is preferably an elastic band. The magic subsides of this department play the effect of supplementary fixed shrouding, set up in the corresponding shrouding outside, can not influence sealedly.
