Abstract

The utility model relates to a disposable moisture absorption article, and in particular relates to a paper diaper with diversion trenches. The paper diaper comprises a water permeable surface layer, a water non-permeable bottom film and an absorption core body arranged between the water permeable surface layer and the water non-permeable bottom film, wherein the water permeable surface layer, the water non-permeable bottom film and the absorption core body are integrated; and a plurality of downward extension diversion trenches are arranged at one side of the absorption core body near the water permeable surface layer along the length direction of the absorption core body. When liquid which is not absorbed by the water permeable surface layer infiltrates the absorption core body, the diversion trenches can rapidly guide infiltrated liquid to two ends of the absorption core body, so that the humidity of the absorption core body below the use part of a user is lower, and therefore, the water permeable surface layer is prevented from becoming damp as much as possible; the water permeable surface layer contacted with the use part of the user is kept dry; the comfort level of users is increased; and bacterial growth possibility is also reduced.

Description

A kind of diaper with guiding gutter

Technical field

This utility model relates to a kind of disposable absorbent article, is specifically related to a kind of diaper with guiding gutter.

Background technology

existing diaper generally all comprises 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, when using diaper to absorb the liquid of user discharge, what absorb at first liquid is the water penetration surface layer, when the water penetration surface layer is not enough to absorb, liquid can infiltrate the absorptive core under it, then slowly diffusion, the defective that existing this diaper exists is: the liquid that begins to absorb due to absorptive core mainly is positioned at the below that user uses the position, and liquid needs could slowly to spread apart for a long time, this just makes user use the absorptive core of below, position very large in long period humidity, therefore, the water penetration surface layer that easily causes this place gets damp, thereby make user use the position can't keep dry and comfortable, and easy breed bacteria.

The utility model content

The problems referred to above for the prior art existence, the purpose of this utility model be to provide a kind of can be fast with the two end portions from the liquid guide flow that oozes under the water penetration surface layer to the length direction of absorptive core, reduce and to be positioned at the humidity of absorptive core that user uses the below at position, thereby prevent that as much as possible the water penetration surface layer from getting damp, make the use position of user keep dry and comfortable diaper as far as possible.

For achieving the above object, this utility model adopts following technical scheme: a kind of diaper with guiding gutter, comprise water penetration surface layer, non-water penetration counterdie and be located at the water penetration surface layer and non-water penetration counterdie between absorptive core, described water penetration surface layer, non-water penetration counterdie and absorptive core are structure as a whole, it is characterized in that: described absorptive core is provided with a plurality of guiding gutters to downward-extension near on a side of water penetration surface layer along the absorptive core length direction.

Further, the width of described guiding gutter is 0.1-0.3mm, and the degree of depth of described guiding gutter is 0.15-0.25mm.

Described guiding gutter is parallel to each other, and evenly arranges along the absorptive core width.

with respect to prior art, the utlity model has following advantage: due on the close side of water penetration surface layer of absorptive core, be provided with a plurality of guiding gutters to downward-extension along the absorptive core length direction, when oozing to the absorptive core under the liquid that the water penetration surface layer does not have to absorb, guiding gutter can be rapidly with under the liquid guide flow that oozes to the two ends of absorptive core, make user use the absorptive core humidity of below, position lower, thereby prevent that as much as possible the water penetration surface layer from getting damp, the water penetration surface layer that uses the position to contact with user is kept dry, improved the comfort level of user, also reduced simultaneously the probability of bacteria breed.

The specific embodiment

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

Embodiment:Referring to Fig. 1, a kind of diaper with guiding gutter, comprise water penetration surface layer 2, non-water penetration counterdie 4 and be located at water penetration surface layer 2 and non-water penetration counterdie 4 between absorptive core 3, water penetration surface layer 2, non-water penetration counterdie 4 and absorptive core 3 can become one structure by gluing or pressing mode, absorptive core 3 is provided with a plurality of guiding gutters 31 to downward-extension near on a side of water penetration surface layer 2 along absorptive core 3 length directions.Preferably be parallel to each other between described guiding gutter 31, and evenly arrange along absorptive core 3 widths.The part that absorbs at first liquid due to diaper is the mid portion of diaper, when being seeped into absorptive core 3 under the liquid that the surface layer of diaper mid portion has not absorbed, the guiding gutter 31 that is arranged in parallel on absorptive core 3 can be more quickly with the two end portions of guiding fluid absorptive core 3, thereby reduce the humidity of diaper mid portion absorptive core 3; The guiding gutter 31 that is arranged in parallel is in addition adding man-hour, and technology controlling and process is convenient.

As optimization, the width of described guiding gutter 31 is 0.1-0.3mm, and the degree of depth of guiding gutter is 0.15-0.25mm.The width of guiding gutter refers to guiding gutter along the size of absorptive core width, the degree of depth of guiding gutter refer to guiding gutter from absorptive core near on a side of water penetration surface layer to the size of lower recess.The width of guiding gutter is too large, easy fracture after absorptive core absorption liquid; The width of guiding gutter is too little, and the refluence effect is undesirable; The degree of depth of guiding gutter is too large, and guiding gutter can form fin along the absorptive core length direction and easily allows user not feel well, thereby reduces comfort level; The degree of depth of guiding gutter is too little, and the effect that flows backwards is undesirable.Through repetition test, the applicant finds that the width when guiding gutter is 0.1-0.3mm, and when the degree of depth was 0.15-0.25mm, the water conservancy diversion effect was the most desirable, and the comfort level of user is the highest, also is difficult for producing simultaneously fracture after the absorption liquid of absorptive core.

During concrete enforcement, a kind of diaper with guiding gutter, comprise successively that stereo enclosure becomes 1, water penetration surface layer 2, non-water penetration counterdie 4 and be located at the water penetration surface layer and non-water penetration counterdie between absorptive core 3, this absorptive core 3 is near on a side of surface layer, be provided with along the absorptive core length direction a plurality of to downward-extension, and the guiding gutter 31 that is parallel to each other; Water penetration surface layer 2, non-water penetration counterdie 4 and absorptive core 3 can become one structure by gluing or pressing mode.
