Description

Technical Field

[0001] The utility model belongs to the field of packaging boxes, and in particular relates to a sealing sticker which is easy to distinguish the opening state. Background Art

[0002] Cosmetics refer to chemical industrial products or fine chemical products that are spread on any part of the human body surface, such as skin, hair, nails, lips and teeth, by smearing, spraying or other similar methods, for the purpose of cleaning, maintenance, beautification, modification and change of appearance, or correction of body odor and maintenance of good condition. Because they act directly on the human body surface, the management of their circulation is very strict.

[0003] At present, in order to prevent the cosmetics packaging box from being opened when consumers return the products, manufacturers usually have some special settings on the opening part of the cosmetics packaging box so that sales staff can quickly identify whether the returned cosmetics packaging box has been opened.

[0004] However, the above-mentioned special configurations cause manufacturers to spend extra costs on cosmetic packaging boxes. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a sealing sticker that is easy to distinguish the opening status. The sealing sticker only needs to be provided with a knife line to realize convenient identification of whether the packaging box has been opened, which significantly reduces the extra cost spent by manufacturers on cosmetic packaging boxes.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A sealing sticker with an easy-to-distinguish opening state is glued to the opening part of a packaging box and has a first end and a second end respectively located on both sides of an opening structural seam, and a straight line extending from the first end to the second end is used as an uncovering direction. The invention is characterized in that it has: a cutting unit located at the first end, the cutting unit includes a first knife line and a second knife line that are close to each other and gradually approach the opening structural seam, the first knife line is a V-shaped fold line with a tip away from the second knife line, and the orthographic projection of the second knife line along the uncovering direction completely blocks the orthographic projection of the first knife line along the uncovering direction.

[0008] Preferably, the second knife line is a straight line or a V-shaped fold line.

[0009] Furthermore, the second knife line is a V-shaped fold line with the tip facing the opening structural seam, and the acute angle of the fold line ranges from 60° to 90°.

[0010] Furthermore, the first knife line and the second knife line are both broken lines formed by two sides of an isosceles triangle, and the first knife line and the second knife line are mirror-symmetrical along the unveiling direction, and a line connecting the tips of the first knife line and the second knife line extends along the unveiling direction.

[0011] Furthermore, the first score line has two straight segments of the first score line, the second score line has two straight segments of the second score line, and the straight segments of the first score line are shorter than those of the second score line.

[0012] Furthermore, the intersection angle of the two straight segments of the first score line is defined as the fold angle of the first score line, the intersection angle of the two straight segments of the second score line is defined as the fold angle of the second score line, and the fold angle of the first score line is smaller than that of the second score line.

[0013] Preferably, the present utility model further includes a reverse notch unit located at the second end. The reverse notch unit includes a third score line, and the third score line is a V-shaped broken line formed by the two waists of an isosceles triangle, and the angle bisector of the third score line extends along the uncovering direction.

[0014] Furthermore, the reverse notch unit further includes a fourth score line, and the third score line and the fourth score line are close to each other and gradually approach the opening structure seam.

[0015] The fourth score line is a V-shaped broken line formed by the two waists of an isosceles triangle, and the orthographic projection of the fourth score line along the uncovering direction completely covers the orthographic projection of the third score line along the uncovering direction. Moreover, the connection line between the tips of the fourth score line and the third score line extends along the uncovering direction, and the third score line and the fourth score line are mirror-symmetrical along the uncovering direction.

[0016] Preferably, the present utility model further includes a glue-killing area extending from the edge of the first end.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] 1. Since the seal sticker for easily distinguishable open state of the present utility model has a cut unit at the first end, the cut unit includes a first cutting line and a second cutting line that are close to each other and gradually approach the opening structure seam. The first cutting line is a V-shaped broken line with the tip away from the second cutting line. The orthographic projection of the second cutting line along the uncovering direction completely covers the orthographic projection of the first cutting line along the uncovering direction. Since the opening of the packaging box must make the structural parts on both sides of the opening structure seam move away from each other, and this can only be achieved by peeling off the adhesively attached seal sticker for easily distinguishable open state. When the seal sticker is uncovered along the uncovering direction to the first cutting line, two tearing lines for the overall structure start to form at both ends of the first cutting line. Continuing to uncover the seal sticker, when reaching the second cutting line, since the orthographic projection of the second cutting line along the uncovering direction is larger than that of the first cutting line, both tearing lines intersect with the second cutting line and terminate at the second cutting line. Thus, when the seal sticker for easily distinguishable open state is completely uncovered, the first cutting line, the two tearing lines, and the second cutting line form a residual sticker remaining adhesively attached to the packaging box. Even if the seal sticker for easily distinguishable open state is adhesively attached to the opening part of the packaging box again, and the residual sticker is separated from the overall structure, the user can easily identify it by observation. Therefore, the present utility model only needs to set the cutting lines to achieve convenient identification of whether the packaging box has been opened, thereby significantly reducing the additional costs consumed by the manufacturer on the cosmetic packaging box.

[0019] 2. Since the second cutting line of the present utility model is a V-shaped broken line with the tip facing the opening structure seam, and the acute angle range of the broken line is 60° - 90°, therefore, the second cutting line of the present utility model is easy to process and form, and the structure of the second cutting line is not easily damaged under a relatively large tearing force and is easy to tear.

Detailed implementation manners

[0027] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the following embodiments will specifically elaborate on the seal sticker with an easily distinguishable open state of the present utility model in conjunction with the accompanying drawings. It should be noted that the descriptions of these embodiments are used to help understand the present utility model, but do not constitute a limitation to the present utility model.

[0028] <Embodiment 1>

[0029] As Figure 1 shown, the seal sticker 100 with an easily distinguishable open state in this embodiment is adhered to the opening part of the packaging box (not shown in the accompanying drawings), and has a first end 100a and a second end 100b respectively located on both sides of the opening structure seam G. The straight extension direction from the first end 100a to the second end 100b is taken as the peeling direction D. Specifically, the packaging box has a box body for accommodating the product and a cover for opening and closing the box body. An opening structure seam G is formed between the box body and the cover. When the cover is opened relative to the box body, the two are separated at the opening structure seam G; when the cover is closed relative to the box body, the two are closed at the opening structure seam G. Therefore, when the packaging box is changed from closed to open, the seal sticker 100 with an easily distinguishable open state must be peeled off from the surface of the packaging box, and it is obvious that the first end 100a to the second end 100b are respectively adhered to the surfaces of the box body and the cover.

[0030] The seal sticker 100 with an easily distinguishable open state has an adhesive area 1 and a glue-killing area 2. Specifically, the adhesive area 1 is fully adhered to the opening part of the packaging box, and its two ends are the first end 100a to the second end 100b.

[0031] The incision unit 11 is located at the first end 100a, and the incision unit 11 includes a first cutting line 111 and a second cutting line 112 that are close to each other and gradually approach the opening structure seam G.

[0032] The first cutting line 111 is a V-shaped broken line with its tip away from the second cutting line 112. The orthographic projection of the first cutting line 111 along the peeling direction D is completely blocked by the orthographic projection of the second cutting line 112 along the peeling direction D, and the second cutting line 112 is a straight line. Specifically, the first cutting line 111 is a V-shaped broken line formed by the two waists of an isosceles triangle. The second cutting line is perpendicular to the peeling direction D, and its layout shape is "<|". The direction perpendicular to the peeling direction D is taken as the pasting width direction. The extension length of the first cutting line 111 in the pasting width direction is less than the extension length of the second cutting line 112 in the pasting width direction, and the acute angle ranges of the broken lines of the first cutting line 111 and the second cutting line 112 are both 60° to 90°.

[0033] The glue-killing area 2 extends and is formed at the edge of the first end portion 100a. Specifically, the glue-killing area 2 has no bonding relationship with the packaging box and is used for consumers to peel off the sealing sticker 100 to easily distinguish the opening state.

[0034] <Example Two>

[0035] In the second embodiment, the same symbols are given to the same structures as in the first embodiment, and the same descriptions are omitted.

[0036] In the second embodiment, the difference between the sealing sticker 100 for easily distinguishing the opening state and that in the first embodiment is as follows:

[0037] As Figure 2 shown, the second cutting line 112 is a triangular broken line, and its layout shape is and one side of the second cutting line 112 is perpendicular to the peeling direction D, that is, this side extends along the pasting width direction. Specifically, the extension length of this side in the pasting width direction is greater than the extension length of the first cutting line 111 in the pasting width direction.

[0038] <Example Three>

[0039] In the third embodiment, the same symbols are given to the same structures as in the first embodiment, and the same descriptions are omitted.

[0040] In the third embodiment, the difference between the sealing sticker 100 for easily distinguishing the opening state and that in the first embodiment is as follows:

[0041] As Figure 3 shown, the second cutting line 112 is a V-shaped broken line with its tip facing the opening structure seam G. Both the first cutting line 111 and the second cutting line 112 are broken lines formed by the two waists of an isosceles triangle, and the connecting line of the tips of the first cutting line 111 and the second cutting line 112 extends along the peeling direction D.

[0042] As Figure 4As shown, the first cutting line 111 has two straight segments 1111 of the first cutting line, and the second cutting line 112 has two straight segments 1121 of the second cutting line. The straight segment 1111 of the first cutting line is shorter than the straight segment 1121 of the second cutting line, so that the positive projection of the second cutting line 112 along the uncovering direction D completely obscures the positive projection of the first cutting line 111 along the uncovering direction D.

[0043] Moreover, the seal sticker 100 with an easily distinguishable opening state further includes an inverse cutting unit 12.

[0044] The inverse cutting unit 12 is located at the second end portion 100b, and the cutting unit 12 includes a third cutting line 121.

[0045] The third cutting line 121 is a V-shaped broken line formed by the two waists of an isosceles triangle. The connecting line of the tips of the third cutting line 121 extends along the uncovering direction D, and the first cutting line 111 and the second cutting line 112 are mirror-symmetrical along the uncovering direction D, and the layout shape is "<>".

[0046] Specifically, when uncovering the seal sticker 100 with an easily distinguishable opening state along the uncovering direction D to the first cutting line 111, two tearing lines 11a for the overall structure start to form at both ends of the first cutting line 111. Continuing to uncover the seal sticker, when reaching the second cutting line 112, since the positive projection of the second cutting line 112 along the uncovering direction is greater than that of the first cutting line 111 or the third cutting line 121, both tearing lines 11a intersect with the second cutting line 112 and terminate at the second cutting line 112. Thus, when the seal sticker 100 with an easily distinguishable opening state is completely uncovered, the first cutting line 111, the two tearing lines 11a, and the second cutting line 112 form a residual sticker 11b with residual glue adhered to the packaging box.

[0047] Specifically, when reversely uncovering the seal sticker 100 with an easily distinguishable opening state along the uncovering direction D to the third cutting line 121, two tearing lines 11a for the overall structure start to form at both ends of the third cutting line 121. Continuing to uncover the seal sticker, when reaching the boundary between the first end portion 100a and the glue killing area 2, both tearing lines 11a intersect with this boundary and terminate at this boundary. Thus, when the seal sticker 100 with an easily distinguishable opening state is completely uncovered, the third cutting line 121, the two tearing lines 11a, and this form a residual sticker 11b with residual glue adhered to the packaging box.

[0048] <Example Four>

[0049] In Example Four, the same symbols are given to the same structures as in Example Three, and the same descriptions are omitted.

[0050] In Example Four, the difference between the seal sticker 100 with an easily distinguishable opening state and that in Example Three lies in:

[0051] AsFigure 5 As shown, the intersection angle of the two first cutting line straight segments 1111 is taken as the first cutting line fold angle 1111a, and the intersection angle of the two second cutting line straight segments 1121 is taken as the second cutting line fold angle 1121a. The first cutting line fold angle 1111a is smaller than the second cutting line fold angle 1121a, so that the positive projection of the second cutting line 112 along the uncovering direction D completely covers the positive projection of the first cutting line 111 along the uncovering direction D.

[0052] <Example Five>

[0053] In the fifth embodiment, the same symbols are given to the same structures as in the third embodiment, and the same descriptions are omitted.

[0054] In the fourth embodiment, the difference between the seal sticker 100 with an easily distinguishable opening state and that in the fourth embodiment lies in:

[0055] As Figure 6 shown, the reverse cutting unit 12 further includes a fourth cutting line 122, and the third cutting line 121 and the fourth cutting line 122 are close to each other and gradually approach the opening structure seam G.

[0056] The fourth cutting line 122 is a V-shaped broken line formed by the two waists of an isosceles triangle. The third cutting line 121 and the fourth cutting line 122 are mirror-symmetrical along the uncovering direction D, and the layout shape is "<>". Moreover, the positive projection of the fourth cutting line 122 along the uncovering direction D completely covers the positive projection of the third cutting line 121 along the uncovering direction D, and the connection line of the tips of the fourth cutting line 122 and the third cutting line 121 extends along the uncovering direction D. Specifically, the cutting unit 11 and the reverse cutting unit 12 are mirror-symmetrical along the uncovering direction D.

[0057] The above embodiments are preferred cases of the present invention and are not used to limit the protection scope of the present invention. Various deformations or modifications that can be made by those of ordinary skill in the art without creative labor within the scope of the appended claims still fall within the protection scope of this patent.
