Description

Packing box tearing head structure and packing box

Technical Field

The utility model relates to a packing box especially relates to a packing box tears first structure of drawing and packing box.

Background

For the theftproof and be convenient for unpacking, usually can set up two perforated lines at the packing box external cover interval parallel in the packing industry at present, the perforated line both ends run through the enclosing cover left and right sides, and the regional tearing strip that forms between two perforated lines, when opening the packing box, from tearing strip one end to the other end tear to accomplish unpacking operation on earth, after unpacking, destroyed tearing strip also can play the theftproof warning effect.

However, the existing packaging box structure still has some inconveniences when the box is unpacked, when the tearing strip starts to be torn, if the force application direction is not opposite, the packaging box plate is thicker, the tearing strip is too long or too wide, and the like, one or more tearing strips occur simultaneously, the tearing operation is more laborious, the tearing strip is not easy to tear and is easy to tear, and once the tearing strip is torn, the unpacking becomes a laborious thing.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a packing box tears first structure of drawing and packing box is provided, can be better compensate the not enough of prior art, tear laborsavingly and be difficult for the tear.

The utility model discloses a realize through following technical scheme:

packing box tears draw head structure, punches on the enclosing cover of packing box and sets up two and tear the line, tears the regional tear strip that can tear the packing box that forms between the line, its characterized in that:

at least one end of the tearing strip is provided with a tearing head which is retracted inside the notch on the outer cover;

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, and the large end of the tearing head is positioned outside the width of the small end;

the notch is in a horn shape with a large opening facing outwards, the notch and the two sides of the tearing head are disconnected through a knife line or a tearing groove, the direction of the notch of the tearing groove is consistent with the opening direction of the notch at the notch, the wide bottom of the groove bottom of the tearing groove is smaller than the width of the groove bottom, and the groove bottom is an acute angle groove bottom.

At least one end of the tearing strip is provided with a tearing head, and the tearing head is retracted inside the notch on the outer cover, 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 and the other end is small, so that sufficient finger contact surface is easy to apply force when tearing is carried out, and the tearing is prevented from being strenuous due to the fact that the tearing strip is too wide, and the tearing head is prevented from being damaged; the horn-shaped notch and the tearing groove on the two sides of the tearing head are disconnected through the horn-shaped knife line or the sharp tearing groove at the bottom of the acute angle groove, the guiding effect on tearing force is realized during tearing, and when the tearing is completed, the labor is saved when the tearing is started.

Furthermore, each tear line comprises a plurality of obtuse-angle bending punched lines, first assembly edges of the obtuse-angle bending punched lines are parallel and level to each other, second assembly edges are bent for more than 90 degrees relative to the first assembly edges towards the inside of the tear line, and the two tear lines are symmetrical along the length direction of the tear line. Compared with the tearing line formed by straight perforating lines, the second forming edge of the obtuse-angle bending perforating line is easier to break the connection between the tearing line and the outer cover when stressed, and the obtuse-angle bending perforating line is more labor-saving and smooth in tearing when torn.

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.

Furthermore, each tearing line further comprises a punching straight line, the punching straight line is located at the joint of the tearing line and the tearing head, and the punching straight line is flush with the first forming edge and is connected with the knife line or the easy tearing groove. The straight line that punches plays the transition effect, tears and draws more laborsaving and difficult tear.

Further, the tearing head is in a fan shape, a trapezoid shape, a semi-ellipse shape or other shapes capable of forming a big end and a small end.

Packing box, including as above arbitrary packing box tear tab structure, its characterized in that: the top of the packing box is provided with a pair of outer cover and inner cover which can be completely or partially overlapped and seal the top of the packing box when being covered, the outer cover and/or the inner cover are/is provided with an adhesive layer which can fix the outer cover and the inner cover together, and the adhesive layer is positioned on the outer side of the tearing strip; the viscose layer is covered with a release layer which can be torn down, and the outer edge profile of the release layer is positioned outside the outer edge profile of the viscose layer. Quick joint sealing when viscose layer structure does benefit to the packing is used for protecting the viscidity on viscose layer from the type layer, also avoids packing in-process viscose layer to glue other article simultaneously, finishes the back at the packing, tears from the type layer, and the lid closes the enclosing cover and can accomplish the packing, convenient and fast.

Furthermore, the release layer is release paper, a plastic release sheet, a plastic release film or other release structures which are easy to tear and not easy to adhere to the adhesive layer.

Furthermore, the upper edge and/or the lower edge of the release layer is/are the upper edge profile and/or the lower edge profile of the Z-shaped broken line to form a protruding easy-to-tear section, and the left edge and the right edge of the release layer are respectively flush with or positioned at the inner side of the left edge and the right edge of the outer cover; if the upper edge of the release layer is the contour of the upper edge of the Z-shaped broken line, the bottom edge of the Z shape is flush with the upper edge of the outer cover or is positioned at the inner side of the upper edge of the outer cover, and the top edge of the Z shape is positioned at the outer side of the upper edge of the outer cover. The easy-to-tear section is convenient for the isolating layer to be torn off from the adhesive layer quickly.

Furthermore, a tearing direction prompting patch is bonded on the release layer to form an extended easy-tearing section. The easy-tearing section is convenient for the isolating layer to be torn off from the adhesive layer quickly.

Furthermore, a tearing reinforcing band is fixedly communicated with the tearing strip and the tearing head along the length direction, and the tearing strip is further prevented from being torn midway.

The beneficial effects of the utility model reside in that:

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

2. 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;

3. one end of the tearing head is large, and the other end of the tearing head is small, so that enough finger contact surfaces are easy to apply force when tearing is carried out, and 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 torn;

4. the obtuse-angle bent punching line is more labor-saving in tearing and smooth in tearing, the punching straight line plays a transition role, and the tearing is labor-saving and not easy to tear;

5. the packing box can be repeatedly used for many times, and is environment-friendly and economical.
