Description
Technical Field
The utility model relates to the field of sanitary products, in particular to a pair of briefs type sanitary towel which accords with human engineering.
Background
Menstrual pants type sanitary napkins generally consist of an absorbent layer comprising a liquid permeable top layer, an absorbent core and a liquid impermeable bottom layer, which are laminated in this order from top to bottom. The outer clothing layer comprises an outer clothing layer, a spandex silk elastic material layer and an inner clothing layer which are sequentially laminated from outside to inside. The garment layer is divided into a front piece and a rear piece with the narrowest part of the garment layer (the narrowest part of the O-shaped ring) as a limit, and the front piece and the rear piece are respectively provided with a left end and a right end.
When a human body moves (walking, squatting, leg lifting and the like), because the legs move forwards and upwards, the upward pulling force is basically generated on trousers, so that the design of underpants and menstrual briefs is suitable for ergonomics, the principle that the front piece should be repaired without leg clamping, the rear piece can be covered by a triangle area and does not exceed the leg lifting line of the triangle area, so that the daily actions such as leg lifting, walking and the like are influenced, and the rear piece can be covered by the hip to the smile line of the buttocks as much as possible, so that the problems of absorber displacement and side leakage and back leakage are reduced.
Referring to fig. 1, the front and rear panels of the conventional panty-type sanitary napkin have the same width, and when the front and rear panels are worn after the front and rear panels are sealed, the seal line 1' is positioned at the left and right ends of the human body, and when a person moves, the front panel is pulled to the position behind the front panel, so-called "leg-clamping" is limited, and the rear panel cannot be wrapped forwards, so that the overall wrapping performance is poor.
