Detailed Description

The following detailed description will be provided for the embodiments of the present invention with reference to specific embodiments, so that how to apply the technical means to solve the technical problems and achieve the technical effects can be fully understood and implemented.

Examples

Referring to fig. 1, 2 and 3, a sanitary napkin with an absorbent core body having a ring groove structure comprises a sanitary napkin body having two side flaps, the sanitary napkin body comprises a bottom layer 1, an absorbent core 2 and a surface layer 3 which are stacked, the flaps and the bottom layer 1 are provided with bonding portions and corresponding anti-sticking release paper 4 for being stuck on a wearer, a flow guiding layer 5 is arranged between the absorbent core 2 and the surface layer 3, the flow guiding layer 5 is positioned at the center of the sanitary napkin body, the absorbent core 2 is provided with an annular indent 7 extending inwards along the peripheral side of the absorbent core 2, the width a of the annular indent 7 is 0.1-10 mm, specifically 5 mm, the flaps at two sides of the sanitary napkin body are symmetrically provided with side sheets 6, one end of the two side sheets 6 close to each other is positioned outside the annular indent 7 and inside the absorbent core 2, four corners of the annular pressure groove 7 are in a fillet structure, the radius r of the annular pressure groove is 0.1-50 mm, and the radius r is 10 mm;

the sanitary towel structure of the technical scheme adopts the technical scheme that the annular pressing groove 7 is arranged at the position, close to the edge, of the traditional absorption core 2, so that the absorption core 2 can be separated by the annular pressing groove 7 after the sanitary towel is worn, and an inner core body and an outer core body are formed, so that the core body can be bent to a certain degree by taking the annular pressing groove 7 as a boundary, the core body can be adapted to the curve of a human body when the sanitary towel is worn, the peripheral side of the absorption core 2 is attached to the surface of the human body, the inner position has a certain absorption space, and the functional partition of main absorption of the core body at the inner position and main leakage prevention of the core body at the outer position is formed;

in this embodiment, the sanitary napkin body is defined to have a longitudinal direction in the longitudinal direction and a transverse direction in the width direction, the face sheet 3 entirely covers the upper surface of the absorbent core 2, and both sides in the transverse direction of the face sheet 3 are adhered to the lower surfaces of the side sheets 6; the positions and the sizes of the annular pressing groove 7 and the side sheet 6 are designed, so that the usability of the annular pressing groove 7 is ensured, a double leakage-proof structure can be formed by matching the annular pressing groove 7 with a round angle structure with the side sheet 6, the sanitary towel cannot be excessively abrupt to the corner structure to rub the skin when being worn, the periphery of the sanitary towel is excessively smooth, and the wearing comfort is improved in appearance;

in this embodiment, the thickness of the absorbent core 2 outside the annular compressed groove 7 is greater than the thickness of the absorbent core 2 inside the annular compressed groove 7. Therefore, the absorbing core 2 outside the annular pressing groove 7 has enough thickness to be attached to a human body to form annular package of the absorbing core 2 in the annular pressing groove 7, and all-round leakage prevention on the peripheral side is formed;

in the concrete production, absorb core 2 including core upper strata, core lower floor and press from both sides and establish the inner core wherein, annular indent 7 is through the shaping of a indent forming mechanism 8, specifically refer to fig. 4, indent forming mechanism 8 is in before being used for not covering at the core upper strata the inner core upper surface forms the primary indent mechanism 81 of cell type structure, is used for forming the secondary indent mechanism 82 of cell type and is used for the ultrasonic bonding mechanism 83 of core upper strata, core lower floor joint after covering at the core upper strata. This kind of production mechanism's design when making annular indent 7, through twice indent shaping, once extrudees the rudiment shape that forms the indent behind the inner core, carries out the secondary indent again after the core upper strata covers, can reduce the inside core material volume of annular indent 7 like this, is convenient for form sunken shape, also provides sufficient deformation space for the core upper strata simultaneously, makes annular indent 7 structure after the shaping more stable, is difficult for taking place deformation and leads to the function to lose.

Meanwhile, in order to achieve a structure with different thicknesses inside and outside the annular pressure groove 7, the primary pressure groove mechanism 81 can extrude the inside of the annular pressure groove 7, and the external extrusion amount is small, or the structure is realized by changing the mold structure of the molding drum.

The two groove pressing mechanisms have substantially the same structure, and are well known to those skilled in the art, and will not be described herein.

Example two

Referring to fig. 5, compared with the first embodiment, in the present embodiment, the annular pressure grooves 7 are arranged intermittently, and are composed of pressure groove regions 71 with a width b of 0.1-200 mm and non-pressure groove regions 72 with a width c of 0.1-200 mm. The widths of the indent region 71 and the non-indent region 72 are not specifically set, and can be within the above range, and the selection of the numerical value depends on the size of the product and the applicable scene; in this way, the liquid-absorbing material of the absorbent core 2 inside and outside the annular compressed groove 7 can be communicated, and after the liquid absorption of the absorbent core 2 inside or when the liquid amount is large, the absorption can be supplemented by the absorbent core 2 outside, thereby avoiding the waste of the liquid-absorbing material and improving the absorption amount.

While the utility model has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the utility model as defined by the appended claims.
