Description
Technical field
One kind is the utility model is related to both without PUR, just can be by non-woven fabrics elastic saturating without stretched non-woven cloth
It is compounded under air film extended state thereon, and the ventilative folding of flexible arc of arc veneer is formed after air-permeable elastic film resilience reset
Crape formula sanitary napkin veneer, belong to amenities manufacturing field.
Background technology
CN204521234U, title " a kind of Leakproof sanitary towl ", including sanitary napkin body (100), sanitary napkin body upper table
Face is provided with fluid layer, and raise up construction camber veneer along its length in the middle part of fluid layer；Arc veneer periphery is provided with least
One of intake chute, by multiple continuous openings in fluid layer, arcuately the circumferentially distributed construction of veneer forms intake chute；Lead
Liquid layer periphery is provided with flank, and the junction of flank and fluid layer is configured to the liquid blocking strip to raise up；Report is provided with the outside of liquid blocking strip
Alarm device, warning device include inductive switch, power supply, drive circuit and buzzer, and inductive switch is used for when detecting liquid
Drive circuit is accessed into power supply so as to drive buzzer sounding.Its weak point：Arc veneer is convex veneer, it is therefore an objective to will
Both do not address how to efficiently reduce contact of the female private part with sanitary napkin by intake chute water conservancy diversion to both sides by centre through liquid
Face, also stored without solution through liquid and absorb problem.
Utility model content
Purpose of design：The weak point in background technology is avoided, design one kind is both without PUR, without stretched non-woven
Cloth, just non-woven fabrics can be compounded in thereon under air-permeable elastic film stretching state, and formed after air-permeable elastic film resilience reset
The ventilative folding crape formula sanitary napkin veneer of the flexible arc of arc veneer.
Design：In order to realize above-mentioned purpose of design.The utility model is in structure design：1st, the film surface of elastic membrane has
The design of many air-vents, is one of the technical characteristics of the utility model.The purpose so designed is：Due to the utility model
The air-permeable elastic film is under tension with nonwoven cloth cover without glue（Without PUR）It is compound, i.e. the film surface of elastic membrane be
It is compound with the direct hot pressing of non-woven fabrics under extended state, the phenomenon that PUR blocks elastic film surface air-vent will not occur.Secondly, bullet
Property ventilated membrane is advantageous in that：First, it can not only make this air-locked elastic membrane become ventilated membrane, and can make to be covered with
The extensibility increase of the elastic membrane of stomata --- it is elastic good, it is effectively improved the expansion and contraction of air-permeable elastic film；Second, use this reality
With new air-permeable elastic film, it can it substitute current sanitary napkin veneer using elastic make caused by manufacturing equipment answer
Miscellaneous, complex manufacturing technology, cost are high, and efficiency is low, and are declined, thoroughly using the sanitary napkin elastic force caused by adhesive positioning elastic
The defects of gas is poor, comfortableness difference.2nd, the elastic membrane with many air-vents is compound with non-woven fabrics hot pressing in a stretched state
Design, is the two of the technical characteristics of the utility model.The purpose so designed is：Because non-woven fabrics has good water preventing ability,
But elasticity is very small, is substantially negligible and disregards.The utility model by elastic membrane under tension with non-woven fabrics hot pressing
Resilience forms the ventilative folding crape formula sanitary napkin veneer of flexible arc, the ventilative folding crape formula sanitary napkin veneer institute structure of the flexible arc after compound
Into sanitary napkin in women in use, i.e. form nest shape and structure, the nest shape and structure both effectively reduced sanitary napkin face with
The contact area of female private part --- be only nest shape sanitary napkin veneer surrounding contacted with female private part, also solve collected through liquid,
Water conservancy diversion is with absorbing problem.3rd, the negative pressure suction inlet that air-vent shapes in elastic membrane is that this practicality is new along the design for being in boss mouth structure
The three of the technical characteristic of type.The purpose so designed is：Elastic film surface by negative pressure ventilation during being punched, its elastic membrane
Negative-pressure ward hole in face（Negative pressure air-out one end）Aperture along being in boss mouth, the boss platform is just just as cloth is multiple in elastic film surface
Hole shape support, film surface should be higher than due to the orifice part of hole shape support, therefore when it is contacted with sanitary napkin absorbent core layer so that inhale
Sandwich layer face is received to be combined in multiple mouthfuls of shape points with the boss mouth of elastic film surface, make between absorbent cores aspect and elastic membrane formation multichannel and
The hollow multi-point support that road road communicates, not only gas permeability is splendid, and has started the precedent of hollow multi-point support.
Technical scheme：A kind of ventilative folding crape formula sanitary napkin veneer of flexible arc, elastic membrane in a stretched state with non-woven fabrics
After hot pressing is compound, elastic membrane resilience, which resets, forces non-woven fabrics to form folding crape arcs of recesses sanitary napkin veneer.
The utility model is compared with background technology, first, without PUR, you can realizes non-woven fabrics and air-permeable elastic film
It is compound, it is ensured that the gas permeability of air-permeable elastic film and non-woven fabrics in itself is not influenceed by PUR；Second, realize air-permeable elastic
Film forces non-woven fabrics to reset shape with the resilience of air-permeable elastic film with non-woven fabric compounded rear, air-permeable elastic film resilience under tension
Into the ventilative folding crape formula sanitary napkin veneer of required elastic arcs of recesses, because arcs of recesses veneer is folding crape face, not only with blocking solution stream
Dynamic function, and with liquid storage, the function of water conservancy diversion；Third, the negative pressure suction inlet edge that air-vent shapes in air-permeable elastic film is in boss
The design of mouth structure, realize air-permeable elastic film and combined with more mouthfuls of shape points between absorbent core layer, not only gas permeability is splendid, and starts
The precedent of hollow multi-point support.
