Description

A kind of simple and easy case lid

Technical field

The utility model relates to packing technique field, specifically, relates to a kind of simple and easy case lid.

Background technology

The case lid of packing chest has a variety of, and some is converted into case lid analogue by the flap at packing chest top, and the case lid of separation type, commonly paper box form, can be separated easy to use, when covering on casing, have and can maintain good stability.

Traditional paper box case lid, its manufacturing process is first separation, then slots, then carry out nail case or stick box shaping after pack.But traditional paper box case lid has following weak point: owing to have passed through nail case or this technique of stick box, the packing after making paper box shaping can only be staggered stacking, and four limits are tied up without any, thus in transit due to automobile bumpiness, easily damage product; Generally adopt metal filament nailing when following closely case, and nailing machine is huger, operative does not note causing accident on duty, can there is the risk being punctured hand by nail when client uses yet; Case lid four limit employs the technique of nail case, to such an extent as to has damaged paperboard surface, and stick box technique generally can only the manual stick box of workman in addition, and the manual dexterity degree of workman is different, and the shaping rear aesthetics of canopy is also different, and this all makes the aesthetic property of case lid greatly reduce; Paper box need be processed through grooving machine, and be all generally that grooving machine processing sent into by paper by workman one by one, process nail case or stick box are also at the completion date adding work virtually simultaneously.

Utility model content

The purpose of this utility model is to provide a kind of simple and easy case lid, manufactures simple and easy to use, convenience when further improves use while cost-saving and safety, and is convenient to bulk transport and improves conveying efficiency, reduces traffic cost.

The purpose of this utility model is achieved in that

A kind of simple and easy case lid, comprise a rectangle lid, the four sides of described rectangle lid stretches out and forms four tegmental walls respectively, the each self-forming in junction broken line of described tegmental wall and rectangle lid, wherein the both ends of two relative tegmental walls cut out a draw-in groove respectively, and the two ends of another two relative tegmental walls form a buckle respectively to extension.

Wherein, described buckle stretches out from the end of the tegmental wall of its correspondence and reduces gradually, and when buckle inserts draw-in groove, the less meeting in end of buckle is easier to insert draw-in groove, and it is more convenient to operate.

More preferably, described draw-in groove comprises the first draw-in groove and the second draw-in groove, and the head end of described second draw-in groove is connected with the end of described first draw-in groove.Wherein, described first draw-in groove to move towards its corresponding broken line parallel, the trend of described second draw-in groove is extend from the end of described first draw-in groove to corresponding broken line.When buckle inserts draw-in groove, the first draw-in groove and the second draw-in groove shape have angle, can the opening of relatively large angle, be convenient to buckle insert wherein, and after being buckled in insertion wherein, a protection face between the first draw-in groove and the second draw-in groove, can be formed, the fixing of buckle can be conducive to.

Wherein, the angle between described second draw-in groove and the first draw-in groove is not less than 90 degree; Preferably, the angle between described second draw-in groove and the first draw-in groove is greater than 90 degree.

Further, described buckle intermediate shear forms a shear line, and described buckle is cut into two parts, and when buckle inserts draw-in groove, a part can be positioned at case lid inside, a part is positioned at case lid outside, strengthens the stationarity of buckle further.

The utility model is owing to have employed technique scheme, compared with prior art there is following beneficial effect: the simple and easy cover structure of the utility model is simple, no longer need to carry out nail case or stick box in the process manufactured, simplify production technology, reduce productive costs; And this structure makes case lid in flat state in the process of bulk transport, superposition of can tiling is convenient to tie up, and is conducive to the protection in packing and transporting, case lid is not easily damaged in the process of transport; Owing to no longer needing to follow closely case, remain the aesthetic property on case lid surface; And avoid the risk that user occurs to be stabbed by nail in use.

Accompanying drawing explanation

By following embodiment of the present utility model and description taken together with the accompanying drawings, other advantage of the present utility model and feature are shown, this embodiment provides by way of example, but is not limited to this, wherein:

Fig. 1 is the sheet structure schematic diagram of a kind of simple and easy case lid of the utility model.

The A portion structure enlarged detail that Fig. 2 is sheet material shown in Fig. 1.

Fig. 3 for sheet material shown in Fig. 1 be folded into case lid after structural representation.

Detailed description of the invention

One preferred embodiment of the simple and easy case lid of the utility model as shown in the figure, can form by sheet material 10 is folding, sheet material 10 comprises a rectangle lid 15, and the four sides of rectangle lid 15 stretches out and forms tegmental wall 11, tegmental wall 12, tegmental wall 13 and tegmental wall 14 respectively.Each tegmental wall with each self-forming in the junction of rectangle lid broken line 16.Wherein the both ends of two relative tegmental walls 12 and tegmental wall 14 cut out a draw-in groove 17 respectively, and the two ends of another two relative tegmental walls 11 and tegmental wall 13 form a buckle 18 respectively to extension.

Shown in composition graphs 2, the head end that draw-in groove 17 comprises the first draw-in groove 171 and the second draw-in groove 172, second draw-in groove 172 is connected with the end of the first draw-in groove 171.Parallel with the broken line 16 between tegmental wall 12 and rectangle lid 15 for the trend being located at draw-in groove 17, first draw-in groove 171 on tegmental wall 12, the trend of the second draw-in groove 172 is extend from the end of the first draw-in groove 171 to this broken line 16.An obtuse angle is formed between second draw-in groove 172 and the first draw-in groove 171.Buckle 18 stretches out from the end of the tegmental wall of its correspondence and reduces gradually, and a shear line 181 is established in the centre of buckle 18, after shear line 181 is sheared, buckle 18 is cut into two parts.

The utility model is owing to being sheet material, and in flat state in the process of bulk transport, superposition of can tiling is convenient to tie up.During use, each tegmental wall is folded along broken line 16, then buckle 18 is inserted draw-in groove 17, form case lid 1.Folding case lid, buckle 18 is sheared line 181 and cuts into two parts, and a part is positioned at case lid inside, and a part is positioned at case lid outside, and therefore the sizing of case lid is fine.

Although the utility model is illustrated hereinbefore according to preferred embodiment, but this does not represent that scope of the present utility model is confined to above-mentioned structure, as long as the equivalent substitution structure that those skilled in the art can develop easily after reading above-mentioned explanation, the equalization done under the spirit not departing from the utility model and scope changes and modifies, and all should be covered by within the utility model the scope of the claims.
