Description

Absorbent product with fit arc-shaped narrow crotch part

Technical Field

The utility model belongs to the technical field of disposable hygienic products, concretely relates to absorption goods with fit narrow crotch portion of body arc.

Background

Absorbent articles, also known as disposable absorbent articles or sanitary products, including diapers, sanitary napkins, pull-ups, and the like, have been widely used in personal care applications, allowing infants and other incontinent individuals to store excreta through the disposable absorbent articles and isolate the excreta from the body, clothing, bedding, and the like of the wearer, thereby improving the convenience of care and protecting the skin of the infants and other incontinent individuals.

The absorption medium of the absorption product is an absorption core body, and comprises a traditional absorption core body and a composite absorption core body, wherein the traditional absorption core body is formed by blending fluff pulp fibers and super absorbent resin particles. At present, the trend of the technical field is to use a composite absorption core as an absorption medium of an absorption product, and the composite absorption core has the characteristics of falling resistance, no fault, no lump, extremely ultra-thin and the like. In terms of structure, the composite absorption core is generally of a 5-layer structure, and comprises an upper covering layer, a lower covering layer and fluffy non-woven fabrics positioned between the upper covering layer and the lower covering layer from top to bottom, and granular super absorbent resin is implanted and embedded into the surface layer and the bottom layer of the fluffy non-woven fabrics respectively.

The traditional process causes the diaper to be thick and heavy, and the crotch part is not proper, so that the movement of the infant is inconvenient. On the other hand, after the absorption core body absorbs liquid, the absorption core body naturally sags under the action of gravity and even heaps and faults are formed, so that the absorption core body is very easy to squeeze or rub the crotch of an infant, inconvenience is brought to the activity of the infant, harm is brought to the health of the infant, and the healthy growth of the infant is influenced.

Most of the current diapers also focus on leakage protection. In order to make the baby more comfortable, the paper diaper is designed to be suitable for the cutting mode of the hip curve of the baby, and the structure of the absorbent product without inner side pressure on the legs of the baby is especially designed, so that the diaper is very important for the healthy growth of the baby.

Therefore, the patent with the publication number of CN203089561U provides a golden double-arc multi-layer core body diaper, which comprises a strip-shaped inner core body arranged in the diaper, wherein the inner core body is provided with concave arc lines for abdicating legs, and the concave arc lines are symmetrically arranged on two sides of the central line of the inner core body along the length direction of the inner core body; the inner core body comprises two end parts and a middle part positioned between the two end parts along the length direction of the inner core body, the width of the middle part is smaller than the width of the two end parts, the two ends of the middle part are respectively connected with the end parts through transition sections, and the transition sections are naturally connected from the middle part to the two end parts in a transition mode in a gradually widening mode. By accurately cutting the radian of the crotch part, a golden ratio double arc is formed, so that the inner sides of the legs of the baby are not stressed, the baby is more comfortable and fit after being worn on the body, and the movement is more convenient and free; and on the basis of ensuring the dryness and leakage prevention of the paper diaper, the paper diaper is lighter, thinner and more breathable, and the inner core body is not broken and does not stick together, thereby being beneficial to the healthy growth of the baby.

For another example, the utility model with publication number CN107361924A discloses a body fitting leakage-proof absorbent article, which comprises a liquid-permeable surface layer, a liquid-impermeable bottom layer and a dumbbell-shaped absorbent core, wherein both sides of the absorbent article in the width direction are respectively provided with a left leakage-proof separation edge and a right leakage-proof separation edge, each leakage-proof separation edge comprises a base portion, a free portion, and a flexible portion connected to the free portion and located at the upper end of the free portion, an elastic body is arranged in the flexible portion to make the leakage-proof separation edge have elastic flexibility in the longitudinal direction, each leakage-proof separation edge further comprises a body fitting connection portion arranged between the base portion and the free portion, the body fitting connection portion is arranged at the edge positions of both longitudinal sides of the crotch portion of the dumbbell-shaped absorbent core, and when the absorbent article is in a natural loose three-dimensional state, the leakage-proof separation edge at the connection portion between the free portion and the body fitting connection portion is inwardly contracted along the width direction of the crotch, each leakage-proof separation edge forms a three-dimensional arc-shaped leakage-proof separation edge in the width direction of the absorbent product.

Although the prior art sets up the absorbent core of absorbent article as the absorbent core that crotch portion is arc structure, also called dumbbell type absorbent core, the both sides of absorbent article still can carry out continuous friction to wearer's shank skin in the use, especially after the absorbent article droops because of the imbibition dead weight, very easily appears the scratch even red swelling inflammation on infant's skin.
