Abstract

The utility model relates to a disposable moisture absorption article and specifically relates to a double-layered absorption core body and a paper diaper. The double-layered absorption core body is long strip-shaped; two sides of the absorption core body in a length direction are relatively folded to form a first folding part and a second folding part; and the first folding part and the second folding part are connected with one side surface of the absorption core body in a pressing or a bonding way. With the above design, a double-layered structure is provided for the absorption core body and thickness of an effective part of the absorption core body is thickened, so absorptive ability of the effective part is strengthened and problems of crack and leakage of the absorption core body after liquid absorption are prevented. The absorption core body of the paper diaper employs the above double-layered absorption core body, so the width of the area covered by the paper diaper is reduced, thereby improving usage comfortableness and most importantly preventing a baby from developing O-shaped legs as far as possible.

Description

A kind of double-deck absorptive core and the paper napkin

Technical field

This utility model relates to a kind of disposable absorbent article, is specifically related to a kind of double-deck absorptive core and the paper napkin.

Background technology

The existing paper napkin generally all comprise non-water penetration counterdie, absorptive core and water penetration surface layer, and absorptive core is between non-water penetration counterdie and water penetration surface layer; To effective absorption portion of user drain, it is in fact the mid portion of paper napkin length direction, but the absorptive core of existing paper napkin thickness is along its length all consistent, this just makes the part in the middle of absorptive core easily rupture owing to absorbing more liquid, the problem of fluid seepage; Generally elongated due to existing absorptive core in addition, the width of whole absorptive core is basic identical, this just makes to be positioned at user and uses the width of paper napkin body partly larger, not only can bring discomfort to user, and also easily forms " O " type lower limb for infant user.

Utility model content

The problems referred to above that exist for prior art, the purpose of this utility model is to provide and a kind ofly can prevents as far as possible absorptive core fracture, makes the paper napkin with double-deck absorptive core of fluid seepage.

For achieving the above object, this utility model adopts following technical scheme: a kind of double-deck absorptive core, described absorptive core is strip, it is characterized in that: the both sides of absorptive core length direction are bent to form to the first kink and the second kink in opposite directions, and described the first kink is connected with a side of absorptive core by pressing or adhesive means with the second kink.

Further, described the first kink and the second kink are arc along the pleat trace of the both sides of absorptive core length direction.

Further, the radian of the pleat trace of described arc is 1 ~ 1.5.

A kind of paper napkin, comprise water penetration surface layer, non-water penetration counterdie and be located at water penetration surface layer and non-water penetration counterdie between the absorptive core of strip, described water penetration surface layer, non-water penetration counterdie and absorptive core are structure as a whole, and described absorptive core is the double-deck absorptive core in technique scheme.

With respect to prior art, the utlity model has following advantage:

1, owing to the both sides of absorptive core length direction being bent to form in opposite directions to the first kink and the second kink, and these two kinks are connected with absorptive core, thereby make this absorptive core there is double-decker, thickeied the thickness of absorptive core live part, improved the absorbability of this part, thereby can effectively prevent from rupturing after absorptive core from absorbing liquid, make the problem of fluid seepage.

2, because the first kink and the second kink are arc along the pleat trace of the both sides of absorptive core length direction, what this made absorptive core is " X " type, and absorptive core in this during for the paper napkin, can effectively be prevented to paper napkin folding shelves.

While 3, using double-deck absorptive core as the absorptive core of the paper napkin, the paper napkin are positioned at user and use the width at position less, this not only can improve the comfort level of user, the more important thing is, can prevent as much as possible the formation of " O " type lower limb for infant user.

Accompanying drawing explanation

The structural representation of Fig. 1-this utility model embodiment.

In figure, the first kink 1, the second kink 2, absorptive core 3.

The specific embodiment

Below in conjunction with drawings and Examples, this utility model is described in further detail.

embodiment 1:double-deck absorptive core, this bilayer absorptive core is strip, the both sides of absorptive core length direction are bent to form to the first kink and the second kink in opposite directions, and described the first kink is connected with a side of absorptive core by pressing or adhesive means with the second kink.

Absorptive core is generally strip, the first kink and the second kink pleat trace on absorptive core length direction can be a straight line equal in length with absorptive core, such the first kink and the second kink are also strip, the first kink and the second kink are connected on a side of absorptive core, for the ease of narration, this side that the first kink and the second kink is connected to absorptive core is called joint face, the first kink and the second kink can have part overlapping on joint face, or have spacing.

Referring to Fig. 1, as preferably, the first kink and the second kink are arc along the pleat trace of the both sides of absorptive core length direction.The corresponding string of pleat trace of this arc and absorptive core equal in length.Such the first kink is the structure consisting of the circular arc string relative with circular arc with the second kink, the first kink and the second kink are connected on a side of absorptive core, the width of absorptive core is narrowed down to mid portion gradually from its two end portions, therefore, more meet ergonomics.

The radian of the pleat trace of arc is too large, the width of absorptive core mid portion can be narrower, although the thickness of mid portion is thicker like this, absorbing power strengthens, but easily produces side leakage, therefore, inventor is through test of many times and data analysis, finally obtain when the radian of the pleat trace of arc is 1 ~ 1.5, absorptive core not only absorbing power is better improved, and is not easy to produce side leakage.

During concrete enforcement, the first kink and the second kink can also be trapezoidal, and now, the first kink and the second kink pleat trace on absorptive core length direction forms by three sections, this three disconnected be respectively trapezoidal two hypotenuses and a minor face.

embodiment 2:a kind of paper napkin, comprise water penetration surface layer, non-water penetration counterdie and be located at water penetration surface layer and non-water penetration counterdie between the absorptive core of strip, water penetration surface layer, non-water penetration counterdie and absorptive core can be by gluing or be pressed into integrative-structure, absorptive core adopts the double-deck absorptive core described in embodiment 1, the both sides that are about to strip absorptive core length direction are bent to form the first kink and the second kink in opposite directions, the first kink be connected with a side of absorptive core by pressing or adhesive means with the second kink and, the first kink and the second kink are arc along the pleat trace of the both sides of absorptive core length direction.

During concrete enforcement, preferably absorptive core is connected to that side of the first kink and the second kink towards non-water penetration counterdie, thus more comfortable when user is used.

Finally explanation: above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although this utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
