The easy to uncover type emplastrum

Technical field

This utility model relates to a kind of emplastrum, is specifically related to a kind of easy to uncover type emplastrum.

Background technology

Emplastrum mainly is made up of substrate and adherent layer, and wherein substrate is made up of ointment layer and backing layer.Because the backing layer of traditional plaster is generally all nonelastic or unidirectional elasticity is arranged, therefore in process of production, backing layer can not had two ends of retractility to be fixed on the transporter; Ointment is housed in the feeding device, and is positioned at the top of backing layer transporter; Drive backing layer by transporter and on its non-bearing of trend, move, allow the interior ointment of feeding device directly coat the surface of backing layer; Again adherent layer is overlying on afterwards on the another side of ointment layer and gets final product.Because what traditional emplastrum adopted is the mode that directly is coated with the ointment layer, therefore in actual production process, can allows the area of adherent layer make and produce the difference level between substrate and the adherent layer greater than chip area.Like this, though can easily substrate be separated with adherent layer, need to increase the usable floor area of backing layer.

Because traditional substrate only has unidirectional elastic force, and elastic range is less, so emplastrum is difficult to the reliability that guarantees that it is applied ointment or plaster when use at frequent active position in the joint etc.For fear of involve sense, comfortableness when improving emplastrum and applying ointment or plaster, people have developed a kind of comprehensive elasticity fillet type emplastrum, the substrate of this emplastrum is all having great retractility aspect length and the width, no matter thereby apply ointment or plaster and all can apply ointment or plaster reliably at any position of human body, it is comfortable to apply ointment or plaster.But in view of existing manufacturing technique, make the substrate of this bidirectional elastic be difficult to be fixed on and directly cover medicine on the transporter, thereby ointment can only be coated earlier and transferred on the backing layer behind the adherent layer.The production technology of this transfer coated method can't make when section and produce the difference level between substrate and the adherent layer, and therefore in use, user is difficult to substrate is separated with adherent layer.

This shows, improve the structure of adherent layer, so that it can be at conservation and does not change under the prerequisite of existing technology, reducing substrate and adherent layer separating difficulty is one of present problem demanding prompt solution.

The specific embodiment

A kind of easy to uncover type emplastrum of this utility model mainly is made up of substrate 1 and adherent layer 2, and wherein substrate 1 comprises ointment layer 1-1 and backing layer 1-2.The ointment layer 1-1 that is overlying on backing layer 1-2 surface has one and fixes on viscosity, and adherent layer 2 and backing layer 1-2 lay respectively at the two sides of ointment layer 1-1, and the cohesive force of ointment layer 1-1 and backing layer 1-2 is greater than the cohesive force of ointment layer 1-1 and adherent layer 2.For in use, can easily substrate 1 be separated with adherent layer 2, offer the branch tangent line 2-1 more than 1 or 1 on the adherent layer 2 described in the utility model.So in use, the user both hands are respectively held on minute emplastrum of the both sides of tangent line 2-1, simultaneously to substrate 1 direction bending emplastrum, this moment adherent layer 2 branch tangent line 2-1 place can be under the effect of bending power to adherent layer 2 directions lift, adherent layer 2 and substrate 1 be at separating opening of its minute tangent line 2-1 place formation.Like this, after user finds this separating opening, just can take advantage of a situation the ointment layer 1-1 of whole adherent layer 2 from substrate 1 opened.

Tangent line 2-1 can be being located on the adherent layer 2 of non-perforation in described minute, and the two ends of promptly dividing tangent line 2-1 are also for extending to the edge of adherent layer 2.But in order can better adherent layer 2 to be opened from ointment layer 1-1, the branch tangent line 2-1 that is opened on the adherent layer 2 is preferably through minute tangent line 2-1, promptly the two ends of this minute tangent line 2-1 all extend to the edge of adherent layer 2, and the branch tangent line 2-1 of above-mentioned perforation is divided into adherent layer 2 more than 2 or 2.This just is equivalent to be coated with simultaneously on the surface of the ointment layer 1-1 of same substrate 1 the little anti-grume more than 2 or 2, and the edge of these little anti-grumes is close to mutually and is combined the area adherent layer 2 identical with shape with the area of substrate 1 with shape.The branch tangent line 2-1 that is opened on the adherent layer 2 can have any shape, as straight line, curve or broken line or the like, and the distribution between many branch tangent line 2-1 both can be parallel, also can intersect.But in order to form separating opening more easily, the shape of described minute tangent line 2-1 preferably can allow the ointment agent when bending, divides the both sides of tangent line 2-1 to form unbalanced force.When being 1, because of trade-off curve or the broken line of trying one's best, referring to Fig. 1 as the branch tangent line 2-1 on being opened in adherent layer 2.As the branch tangent line 2-1 on being opened in adherent layer 2 is 1 when above, can be opened in U-shaped line on the adherent layer 2 for symmetry, referring to Fig. 2.
