Description

Disposable sensitization anti-false sign

The utility model relates to a kind of mark, is a kind of being used in the packing of product exactly, has that the reservation that can not remove had been opened or the mark of used vestige, or is used for the mark of product false proof.The utility model is made up of reference lamina and the overlayer be located on the reference lamina, on contacted of overlayer wherein and the reference lamina tack coat is arranged.

China's utility model patent 92243695.9 discloses a kind of " disposable false proof seal laber ", this patent is to be made of overlayer, printed layers, tack coat etc., this label is attached to sealing place, when opening overlayer, the supratectal tack coat printed layers that it is set is down glued down, produce the sign that sealing place has been opened, reach false proof purpose.Similar to this patent is Chinese utility model patent 92244289.4 disclosed " compound stealthy label ".The aftermentioned patent is by plastic foil, adhesive-layer, form from shape layer, the reference lamina that has a color, and at unused state, plastic foil is covered with reference lamina, promptly exposes sign under it when opening plastic foil.The deficiencies in the prior art are that this having recorded is opened or used sign itself is repaired again and reused easily, and lose false proof effect; Another deficiency is that the manufacture craft of sign is comparatively simple, is made by lawless people easily.

The purpose of this utility model provides a kind of disposable anti-false sign that overcomes the prior art deficiency, and it can forever keep the mark that is opened or has been used, can not reuse once more, also is difficult for being made by lawless people.

The purpose of this utility model realizes by following measure: its color and luster is with the characteristic that deepens after utilizing photosensitive material to be subjected to illumination, use photosensitive material, as the printing paper of common not sensitization or the egative film of not sensitization etc., make reference lamina, the overlayer that has tack coat on it is being set on reference lamina, and overlayer wherein is provided with dark light-proof material.

The also available following measure of the purpose of this utility model realizes:

On the reference lamina that photosensitive material is made, do not adopting the mode of printing to be printed on certain mark in advance under the sensitization state, for example the part of certain pattern or certain pattern.

Overlayer of the present utility model can combine with light transmissive material and light-proof material, as on light transmissive material, being printed on lighttight certain dark pattern or part pattern in advance, perhaps, be on light transmissive material, to fix pattern or the part pattern that certain light-proof material is made in advance.

The utility model can embed or with the seal location place of glue fixing and packaging box, perhaps fix with glue at the seal location of the packing of product.The utility model also can directly be arranged on the product.

The utility model in use, the reference lamina that photosensitive material is made during overlayer on removing reference lamina is exposed, its color and luster is deepened gradually, and can not change again or by " reparation ", produce nonvolatil being opened or used mark thus.

The utility model has the advantages that: 1, can overcome the deficiencies in the prior art, after the packing of product is opened, stay the mark that to remove; 2, when adopting at the prior impressing pattern of reference lamina or/and adopt light transmissive material to make, and employing is printed on lighttight certain dark pattern or part pattern in advance on the overlayer of light transmissive material system, perhaps, on light transmissive material, in advance when being fixed with certain lighttight pattern or part pattern, can make sign itself that multiple variation is arranged; 3, because photosensitive material color and luster after exposure deepens that one section process is arranged, so the utility model can roughly be estimated the time that product is opened within the specific limits; 4, since the utility model need in the darkroom, carry out when making, to certain requirement of having created conditions, difficult for amateur production of units.

Accompanying drawing 1～5 is several embodiment of the present utility model, and Fig. 6 is the signal of the utility model practical application, below in conjunction with the accompanying drawing explanation.

Fig. 1 is a most basic a kind of embodiment of the present utility model, and (1) is overlayer among the figure, and (2) are reference lamina, and (3) are the bottom under the reference lamina.The overlayer of present embodiment (1) is to use light-proof material, and as black paper, or dark plastics etc. make, and goes up and the contacted face of reference lamina (2) scribbles dung at overlayer (1).Reference lamina (2) is to use the not photosensitive material of sensitization, and for example printing paper is made.Under the non-sensitization condition overlayer (1) is being covered on the reference lamina (2).But a side by the packing box sealing part of sign embedded product shown in Figure 1, or be fixed in the sealing part of the packing of product with glue, the part that overlayer on it (1) stretches out reference lamina is fixed in the opposite side that the packing of product is sealed, in the time will unpacking, overlayer (1) is promptly thrown off from reference lamina, make reference lamina (2) sensitization, its white reference lamina begins painted and deepens gradually, stays permanent marker.

Fig. 2 is another kind of embodiment, and its reference lamina (2) is gone up the triangle (4) that is printed on a dark color under sensitization state not in advance.When packing is opened overlayer (1) is thrown off from reference lamina (2), what at first see is the triangle (4) that a dark color is arranged on white substrate, and prolong in time, reference lamina (2) beginning of white is painted, and its color and luster is deepened gradually, finally becomes the triangle that a dark color is arranged in the dark substrate as shown in Figure 3.

Be on transparent overlayer (1), to be printed on lighttight dark annulus (5) among Fig. 4, and reference lamina is described consistent with Fig. 2, promptly under sensitization state not, on the reference lamina (2) that photosensitive material is made, is printed on the triangle (4) of a dark color in advance.The overlayer (1) that to scheme to scribble in (4) dung under non-sensitization condition is covered on the reference lamina (2), and makes supratectal annulus (5) be arranged in the triangle (4) that is printed on the reference lamina (2).Because the effect of transparent overlayer (1) has just made the reference lamina sensitization it under before throwing off overlayer, form dark substrate, and, the effect of the light tight annulus (5) on the overlayer (1) leaves the annulus of sensitization not on the reference lamina (2) owing to making.Visible mark as shown in Figure 5 after throwing off cap rock (1), the white annulus (6) that the dark triangle (4) that stamps is promptly arranged on the reference lamina (2) of dark color and form because of prior not sensitization.Prolong in time, the annulus (6) of white also becomes dark color, only leaves the triangle (4) and the dark substrate that stamp on it, becomes mark shown in Figure 3, forms nonvolatil mark thus.

Fig. 6 is that the utility model is used for the signal on the packing box.On one side (7) of the sealing part of packing box with embedding, as embed when making box, or fix the mark layer (2) that coverture (1) is arranged on it with glue and go to the bottom or bottom, and stretching out an end of reference lamina, coverture is fixed on the other end (8) that packing box seals, when opening the lid, coverture (1) is thrown off from reference lamina, as seen from the figure, has stayed nonvolatil mark on reference lamina (2) after packing box is opened.

A kind of embodiment of the present utility model directly is fixed with described sign outside product, with the anti-false sign as product.After throwing off overlayer, reference lamina does not gradually become painted by painted, with the difference fake products.
