Abstract

An object imprinting sample collecting tablet is characterized in that: the utility model comprises a transparent protective film, an anti-sticking layer, a substrate layer, and a non-drying glue layer, the protective film and the anti-sticking layer are connected to the two terminals of the substrate layer respectively, the non-drying glue layer is attached to one side of the substrate, and the anti-sticking layer is bent and covered on the surface of the non-dry glue layer, further the protective film is bent and covered on the outer lateral of the anti-sticking layer. The utility model has the advantages of simple structure, convenient operation, low price, non-pollution of collected samples, and clear presentation of minutiae feature.

Description

Object impression sample collection sheet

Technical field

The utility model relates to a kind of object impression sample collection sheet, particularly a kind of object impression sample collection sheet that utilizes adhesive sticker and transparency protected film production.Be mainly used in case/incident fact-finding process the impression sample of the suspicion objects such as vehicle tyre of gathering shoes that the suspect wears and use.

Background technology

Prior art has printing ink stamp method and carbonless copying technology.Wherein printing ink stamp method need gathered coating one deck printing ink on the object, and to being a kind of pollution by gathering object, operation is also very inconvenient; And carbonless copying technical price costliness, collection effect is poor, ignores the minutia of object easily, can not reflect the specificity of object.

Summary of the invention

The purpose of this utility model just provides a kind of object impression sample collection sheet, and to solve prior art when gathering object impression sample, the minutia reflection is not obvious, pollutes easily and is gathered object, the problem of inconvenient operation.

The technical scheme that the utility model adopted is: comprise transparent protective film, adherent layer, substrate layer and non-drying glue layer; diaphragm and adherent layer are connected to the two ends of substrate layer; non-drying glue layer is attached to a side of described substrate layer; described adherent layer bending covers the surface of this non-drying glue layer, and described diaphragm bending covers the outside of this adherent layer.

Described substrate layer adopts plastics, paper or other materials is made and with mutual bonding connection of described diaphragm and adherent layer; Described non-drying glue layer adopts inferior light adhesive sticker.

The utility model has the advantages that: simple in structure, easy to use, cheap, can not pollute and be gathered object, the minutia reflection is obviously.

Embodiment

Referring to Fig. 1～Fig. 5; the utility model comprises diaphragm 3, adherent layer 2, substrate layer 1 and non-drying glue layer 4; diaphragm 3 and adherent layer 2 are connected to the two ends of substrate layer 1; non-drying glue layer 4 is attached to the inboard of described substrate layer 1; 2 bendings of described adherent layer cover this non-drying glue layer 4 above, described diaphragm 3 bendings cover the outside of this adherent layer 2.

Described diaphragm 3 adopts transparent membrane (or opaque material) to make; Described substrate layer 1 can adopt plastics, paper or other materials to make, and the bending edge 11 at its two ends is bonding mutually with the fillet of described diaphragm 3 and adherent layer 2; Described non-drying glue layer 4 adopts inferior light adhesive sticker.

Described non-drying glue layer 4 glues and gets the materials of being gathered on the object such as dust as the background and the carrier of object trace; Adherent layer 2 is protection non-drying glue layer 4 before the transportation neutralized product uses, and prevents that non-drying glue layer 4 from being polluted.Adherent layer 2 adopts the conventional separate paper that is coated with non-adhesive material, is convenient to open; Transparent protective film 3 is used to protect the object impression of collection, has transparent effect preferably, in case influence picture quality when taking pictures.On its arris line, be provided with scale 5, so that Taking Pictures recording, the big photo of the making original and measurement size.

Using method of the present utility model and principle of work are as follows:

On common and object that ground contacts, can be stained with small material grainses such as dust, with these transfer of granules to carrier the time with background, the background of carrier can reflect the surface of contact shape that contacts object with contrast between the particle, the impression that forms when this surface of contact shape contacts with ground with object has certain similarity, therefore the shape that has all reflected object just has the value of comparison and evaluation.

At first transparent protective film 3 is opened during use; then adherent layer 2 is opened; allow the suspicion object on non-drying glue layer 4, press; can stay the impression of object on the non-drying glue layer 4; at last transparent protective film 3 is sticked to non-drying glue layer 4; the impression that prevents object is damaged, and fills in corresponding informance in corresponding position.

Claims

1. object impression sample collection sheet; it is characterized in that: comprise transparent protective film, adherent layer, substrate layer and non-drying glue layer; diaphragm and adherent layer are connected to the two ends of substrate layer; non-drying glue layer is attached to a side of described substrate layer; described adherent layer bending covers the surface of this non-drying glue layer, and described diaphragm bending covers the outside of this adherent layer.

2. object impression sample collection sheet according to claim 1 is characterized in that: described substrate layer adopt be made of plastic or paper and with mutual bonding connection of described diaphragm and adherent layer; Described non-drying glue layer adopts inferior light adhesive sticker.
