Description
Technical Field
The utility model relates to a double-sided tape technical field especially relates to a double-sided tape structure of anti-overflow glue.
Background
The double-sided adhesive tape is a roll-shaped adhesive tape which is prepared by using paper, cloth and a plastic film as base materials and uniformly coating an elastomer type pressure-sensitive adhesive or a resin type pressure-sensitive adhesive on the base materials, and consists of the base materials, an adhesive, release paper (film) or silicone oil paper. As the usage scenarios of the double-sided adhesive tape become more and more complicated, that is, the amount of the double-sided adhesive tape used is large, the double-sided adhesive tape also needs to be stored in a good manner. For example, the roll-core type double-sided tape has a certain thickness of the substrate, so that when the double-sided tape is stored, the double-sided tape may be stuck with some paper scraps or other impurities affecting the quality of the double-sided tape due to the glue overflow, and the use experience of a user may be affected.
Therefore, a double-sided adhesive tape with a more reasonable structure is urgently needed in the market.
SUMMERY OF THE UTILITY MODEL
Aiming at the defects in the technology, the utility model provides a double-sided adhesive tape structure for preventing the overflow adhesive tape; the problem that the side of a base material is affected by glue overflow of the existing double-sided adhesive tape in the background art is solved.
In order to realize the above-mentioned purpose, the utility model provides an anti-overflow adhesive's double faced adhesive tape structure, establish from type layer and clamp including first, second from type layer substrate between type layer, substrate and first from type layer and second are provided with first, second ya keli glue film between the type layer respectively, first type layer is provided with first plane portion, first plane portion with first ya keli glue film is hugged closely, first plane portion's both sides extend and form first side portion, first side portion to first ya keli glue film lateral buckling just hugs closely on the side surface of first ya keli glue film.

Detailed Description
In order to make the present invention clearer, the present invention will be further described with reference to the accompanying drawings.
The utility model provides a double-sided adhesive tape structure for preventing glue overflow, please refer to fig. 1, which comprises a first release layer 1 and a second release layer 2; and press from both sides and establish substrate 3 between first type layer 1, the second type layer 2, substrate 3 and first type layer and second are provided with first ya keli glue film 4, second yakeli glue film 5 respectively from type layer, first type layer is provided with first plane portion 11, first plane portion 11 is hugged closely with first yakeli glue film 4, the both sides of first plane portion 11 extend and form first side portion 12, first side portion 12 is buckled to first yakeli glue film 4 one side and is hugged closely on the side surface of first yakeli glue film 4. In a general double-sided tape structure, a base material is generally a tissue paper base, and then an acrylic adhesive layer is coated on upper and lower surfaces of the tissue paper base, that is, the side of the tissue paper base where adhesive overflow may occur is also coated and isolated by a release paper. The double-sided tape is not sealed in the prior art, although a plastic bag is usually wrapped when the double-sided tape is sold out of a factory, in practical life, the double-sided tape cannot be used up at one time, and overflow glue on the side is adhered to other impurities such as paper scraps and dust when the double-sided tape is stored, so that the quality of the double-sided tape is not affected, and the double-sided tape is used by pinching a roll core type double-sided tape with double fingers by a user, the double-sided tape is not pinched on the side, and the side of the acrylic adhesive layer is contacted, so that the use experience is very bad. And utilized to cover the side from type paper, not only can the separation external impurity with dampproofing, also can be better tear when using from type paper, because the coverage of side is less relatively, tear the upper strata can be more convenient find the point of entry tear from type paper.
As a more preferable mode, the first side surface portion 12 is closely attached to the side surfaces of the first acrylic adhesive layer 4, the base material 3, and the second acrylic adhesive layer 5 in sequence. Although the first side surface part is covered by the first acrylic adhesive layer, the use experience can be improved to a great extent, and the contact area between the acrylic adhesive layer and the outside is also reduced, as a more roll core type double-sided adhesive tape, the side surface can be completely covered,
in this embodiment, the thickness of the first side surface portion 12 is smaller than that of the first plane portion 11 because the plane portion is to ensure that the phenomenon that the first plane portion is too thin and the adhesive residue is too much does not occur when the tape is torn, and the first side surface portion of the side surface is sufficient only to play a certain role of blocking, so that the thickness of the side surface portion should be smaller than that of the plane portion without affecting the overall thickness of the tape and in consideration of cost saving.
In the present embodiment, referring to fig. 2, similarly, in order to make the product symmetrical and beautiful, two sides of the second plane portion 21 extend to form a second side portion 22, and the second side portion is bent toward one side of the second acrylic adhesive layer and is tightly attached to the side surface of the second acrylic adhesive layer; first plane portion hugs closely on the side surface of first ya keli glue film, brings to the double faced adhesive tape of some non-book heart type to say, can all set to the structure that has side portion from type paper two-layer from top to bottom completely, hugs closely first ya keli glue film and second ya keli glue film respectively, and more preferred is that the thickness of first, second side portion is unanimous, can not influence beautifully.
In this embodiment, please refer to fig. 3, the first side surface is sequentially attached to the first acrylic adhesive layer and the side surface of the substrate, and the second side surface is attached to the side surface of the second acrylic adhesive layer, because in the actual production process, it is required to ensure that the acrylic adhesive layer has a certain layer thickness to ensure a certain viscosity, the first and second acrylic adhesive layers are 30-60um thick, the corresponding substrate is 20-40um thick, and the first and second flat surfaces are 90-140um thick; that is, the thickness of the first and second side portions is smaller than 90 um.
The utility model discloses when using, to roll up heart type's double-sided tape as an example, take off whole sticky tape earlier, paste earlier on the material surface that needs to paste, then take off first from the type layer and paste. After the double-sided adhesive tape is used for a certain length, the side face of the residual unused double-sided adhesive tape is isolated and protected by the first side face part, and the failure part is greatly reduced.
The utility model has the advantages that:
the conventional double-sided tape cannot well protect the side surface of the tape after being used, the overflowing adhesive can be infected with dust or other impurities, so that the service life of the tape is shortened, the protection of the first side surface part can well isolate the side surface of the tape from the outside, and the service life of the tape is prolonged; when a user takes the double-sided adhesive tape, the adhesive does not touch the overflow of the side edge of the adhesive tape, so that the experience of the user is improved; and have had this side portion to let the user can be better tear from type paper, facilitate the use.
The above disclosure is only for the specific embodiments of the present invention, but the present invention is not limited thereto, and any changes that can be made by those skilled in the art should fall within the protection scope of the present invention.
