Abstract
The invention relates to the technical field of hygienic products, and provides an absorbing core. The absorbing core comprises an absorbing core body, the absorbing core body comprises a coating layer, a surface layer, a first adhesive layer, a middle layer, a second adhesive layer and a bottom layer, wherein the surface layer, the first adhesive layer, the middle layer, the second adhesive layer and the bottom layer are sequentially arranged in an overlapped mode, the coating layer coats the surface layer, the middle layer and the bottom layer, and a third adhesive layer is arranged between the bottom layer and the coating layer; compared with those of the middle layer, the two ends of the side edges of the surface layer, the two ends of the side edges of the first adhesive layer and the two ends of the side edges of the second adhesive layer retract toward the middle, four open grooves denting toward the middle are formed by the two ends of the side edges of the surface layer, the two ends of the side edges of the first adhesive layer and the two ends of the side edges of the second adhesive layer as well as the two ends of the side edges of the coating layer and the middle layer, the two ends of the side edges of the middle layer are spaced from the inner wall of the coating layer by 3-15 mm respectively, and the two ends of the side edges of the bottom layer are connected with the inner wall of the coating layer. The problems that the two ends of the bottom layer and the two ends of the middle layer of the absorbing core body are poor in absorbing effect and used insufficiently are solved.
Description
Technical field
The present invention relates to hygienic article technical field, particularly to a kind of absorptive core.
Background technology
At present in disposable sanitary articles, wherein absorptive core accounts for Main Function, and absorptive core is to play water conservancy diversion, absorb, store, pin the function of liquid and determine the quality of product.In the past in order to enable absorptive core more preferably to absorb liquid, it uses " sandwich " absorptive core to improve the speed absorbing body fluid, described " sandwich " absorptive core is divided into three layers, top layer, middle level, bottom, each layer is combined by fine hair oar and the polymeric absorbent resin particle of varying number.The bulk density of its top layer and bottom is less than middle level bulk density, because absorptive core is first to absorb from top layer to be absorbed by middle level, bottom and then and pin when absorbing body fluid.Being by substantial amounts of fine hair oar and the zoarium of polymeric absorbent resin particle because of middle level again, can expand after absorption, thus can produce the phenomenon of " colloid obstruction ", the absorber in its lower floor cannot absorb, and the waste causing material is little with absorbtivity.Absorptive core in the most existing disposable sanitary articles is vertical bar shaped, dumb-bell shape, hourglass shape design form, vertical bar shaped core body absorbtivity is big, but polymeric absorbent resin can expand several times after absorbing body fluid, and front and back width is consistent with crotch width, in use process, user can feel that substantial amounts of dilatant is deposited in crotch and does not feels well.Dumb-bell shape, hourglass shape meet human body physiological characteristics but decrease the absorbtivity of crotch, thus the left and right sides can be caused to there is the risk of side leakage.
Summary of the invention
Therefore, for above-mentioned problem, the present invention proposes the absorbing material that a kind of infiltration rate is fast, make full use of in core body, the absorptive core that can prevent left and right sides side leakage.
For solving this technical problem, the present invention takes below scheme: a kind of absorptive core, including absorptive core body, described absorptive core body includes clad and the top layer being cascading, first bonding glue-line, middle level, second bonding glue-line and bottom, described clad is coated on top layer, outside middle level and bottom, the 3rd bonding glue-line it is provided with between described bottom and clad, described top layer, first bonding glue-line and second bonding glue-line side two ends respectively compared with side two ends, middle level all to centre indentation, described top layer, the side two ends of the first bonding glue-line and the second bonding glue-line constitute four flutings to medial recess with the side two ends in clad and middle level, side two ends, described middle level and clad inwall are respectively separated 3mm-15mm, described bottom side two ends are all connected with clad inwall.
Further improving, described absorptive core body is vertical bar shaped or dumb-bell shape.
Further improve, the side two ends of described top layer, the first bonding glue-line and the second bonding glue-line respectively compared with side two ends, middle level all to centre indentation 5mm-30mm.
Further improving, described clad is liquid permeability toilet paper or non-woven fabrics.
Further improving, described top layer, middle level and bottom all include fine hair oar and polymeric absorbent resin particle.
By using preceding solution, the invention has the beneficial effects as follows: pass through top layer, the side two ends of the first bonding glue-line and the second bonding glue-line all form multiple fluting to middle indentation respectively compared with side two ends, middle level, two ends, middle level and clad interval arrange i.e. past relative to bottom middle indentation, the absorptive core making the present invention takes full advantage of absorptive core bottom, polymeric absorbent resin with rear and front end, middle level, absorptive core body is when absorbing body fluid, through both sides fluting absorptive core under the effect by leg grip force and extruding, the naturally regular bending along with the feature of Human Physiology, prevent crotch that substantial amounts of deposit occurs, improve infiltration rate and also reduce the risk of left and right sides side leakage simultaneously, and it is the most comfortable when dressing, skin is made to keep dry and comfortable.
Accompanying drawing explanation
Fig. 1 is the lateral cross section structural representation of the embodiment of the present invention.
Detailed description of the invention
In conjunction with the drawings and specific embodiments, the present invention is further described.
nullWith reference to Fig. 1，The preferably absorptive core of the present invention，Including absorptive core body，Described absorptive core body is vertical bar shaped，Described absorptive core body includes clad 1 and the top layer 2 being cascading、First bonding glue-line 3、Middle level 4、Second bonding glue-line 5 and bottom 6，Described clad 1 is coated on top layer 2、Middle level 4 and bottom 6 are outside，The 3rd bonding glue-line 7 it is provided with between described bottom 6 and clad 1，Described top layer 2、First bonding glue-line 3 with second bonding glue-line 5 side two ends respectively compared with side two ends, middle level 4 all to centre indentation 8mm，Described top layer 2、First bonding glue-line 3 and the side two ends of the second bonding glue-line 5 constitute four flutings 8 to medial recess with the side two ends in clad 1 and middle level 4，Side two ends, described middle level 4 and clad 1 inwall are respectively separated 8mm，Described bottom 6 side two ends are all connected with clad 1 inwall，Described clad 1 is liquid permeability non-woven fabrics，Described top layer 2、Middle level 4 and bottom 6 all include fine hair oar and polymeric absorbent resin particle，Wherein fine hair oar and the polymeric absorbent resin particle density in middle level 4 is higher than top layer 2 and bottom 6，Described first bonding glue-line 3、Second bonding glue-line 5 and the 3rd bonding glue-line 7 are PUR and are formed.
