[0002] Menstrual pants, also known as female physiological pants, are underwear specially used for women during their menstrual period. Their basic structure is to add a layer of waterproof fabric at the bottom and back of the underwear, which can effectively prevent the occurrence of side and back leakage of menstrual blood. The current structure is shown in Chinese patent application CN 106535847 A, which is a disposable underpants, comprising: a ventral part and a dorsal part, the ventral part and the dorsal part are joined to each other by two joining parts at both ends along the waistline direction; a crotch part, the crotch part spans over two central parts joined to the ventral part and the dorsal part; a waist opening, the waist opening is formed by the two upper edges of the ventral part and the dorsal part; left and right leg openings, the left and right leg openings are formed by the ventral part, the dorsal part and the crotch part; a waist elastic part, the waist elastic part extends along the waistline directions of the ventral part and the dorsal part; and a first elastic part, the first elastic part rises from the lower part of the each joining part of the ventral part to the upper edge side and extends to the center of the waistline direction; its shape is to expand from the waist opening to the left and right leg openings below, and the central part of the upper edge of the ventral part is lower than the upper edge of the dorsal part.

[0003] The above technical solution shows that current disposable underwear or menstrual pants and other similar products have the problem that the waistline cannot fully fit the consumer. This technical solution designs a shorter crotch structure to avoid pressure around the wearer's navel and ensure stability when worn.

[0004] As for underwear products, under the premise of uniform elasticity of the outer sheet, the hip circumference of most wearers will be larger than the waist circumference. Under the traditional structure, the sealing edge of the waist circumference is in a straight edge sealing state (such as CN 106535847A Figure 4 As shown in the figure, the hip circumference and waist circumference of the underwear are consistent and cannot completely fit the wearer. Utility Model Content

[0005] Therefore, the utility model provides a closed wearable nursing product with front and rear equilateral waist openings welded in one body, which solves the problem that the existing underwear-type products cannot fit the waist and buttocks curves of the human body.

[0006] In order to achieve the above object, the utility model is realized by the following technical solutions:

[0007] A closed wearable nursing product with front and back equilateral waist openings welded in an integrated manner, comprising a main body formed by cutting an elastic sheet, a crotch piece arranged at the center of the main body, the length direction of the main body being defined as the longitudinal direction, and the width direction being the transverse direction, the main body being divided into a front piece, a crotch portion, and a back piece according to the position when worn, the ends of the front piece and the back piece having the same transverse width, being symmetrically folded and welded and sealed on both transverse sides to form a sealing edge, the distance between the two sealing edges gradually increasing from the longitudinal end of the main body to the crotch position, forming a bevel sealing structure.

[0008] Preferably, the body at both lateral sides of the crotch position is provided with leg openings for wearing, and the lateral width of the front piece at the leg openings is smaller than the lateral width of the back piece.

[0009] Preferably, the width of the sealing edge is 0.1-5 mm.

[0010] Preferably, the inclination angle of the sealing edge to the vertical direction is 0.5-30 degrees.

[0011] Preferably, the sealing edge is formed by ultrasonic welding or hot melt welding.

[0012] Preferably, the lateral width of the crotch piece on the back piece is greater than the lateral width of the crotch piece on the front piece; when the main body is folded and sealed, the crotch piece on the front piece is within the coverage range of the crotch piece on the back piece.

[0013] By adopting the above technical solution, the beneficial effects of the utility model are:

[0014] This technical solution is improved on the basis of traditional trouser-type nursing products, and a slanted welded sealing edge is designed to make the product's appearance design conform to the size of the human body's hip and waist circumference. Under the condition of uniform elasticity of the sheet, the lateral width at the hip position is increased, and the lateral size at the waist circumference is relatively shortened to form an appearance structure that better fits the human body's waist and hip curves, thereby improving the fit of the product, avoiding dislocation during activities, and avoiding situations where the waist circumference is too loose and the hip circumference is too tight, thereby ensuring comfort.

[0020] The following will describe the implementation methods of the present invention in detail in conjunction with specific embodiments, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0021] refer to Figures 1 to 4 A closed wearable nursing product with front and back equilateral waist openings welded in an integrated manner, comprising a body 1 formed by cutting an elastic sheet, a crotch piece 2 being arranged at the center of the body 1, the length direction of the body 1 being defined as the longitudinal direction, and the width direction being the transverse direction, the body 1 being divided into a front piece 11, a crotch portion 13 and a back piece 12 according to the position when worn, the ends of the front piece 11 and the back piece 12 having the same transverse width, and the two transverse sides are welded and sealed after symmetrical folding to form a sealing edge 14, and the welding form is ultrasonic welding or hot-melt welding; the distance between the two sealing edges 14 gradually increases from the longitudinal end of the body 1 to the crotch portion 13, presenting a bevel sealing structure; structurally, the width D1 of the sealing edge 14 is any value in the range of 0.1-5 mm; the inclination angle α of the sealing edge 14 to the vertical direction is 0.5-30 degrees, and can be arbitrarily adjusted according to the product size and design requirements to form a variety of product models to suit people of different body shapes.

[0022] The technical solution is improved on the basis of the traditional trouser-shaped nursing products, and a slanted welded sealing edge 14 is designed, so that the product's appearance design conforms to the size of the human hip and waist. Under the condition of uniform elasticity of the sheet material, the lateral width of the hip position is increased, and the lateral size of the waist is relatively shortened, so as to form an appearance structure that better fits the waist and hip curves of the human body, thereby improving the fit of the product, avoiding dislocation during activities, avoiding the situation where the waist is too loose and the hip is too tight, and ensuring comfort;

[0023] During the molding process, the conventional structure of the front sheet 11 and the back sheet 12 being equal in length is adopted, and then after being folded and sealed, the edges on both sides are cut off, and the cutting edge 151 of the cutting portion 15 is 0.5-5 mm away from the margin D2 of the sealing edge 14, so as to form the inclined sealing edge 14 structure and ensure that the structure of the sealing edge 14 is stable and meets the processing and molding process. For details, see Figure 2 ;

[0024] Structurally, the body 1 is provided with leg openings 16 for wearing at both sides of the crotch portion 13, and the lateral width of the front sheet 11 at the leg openings 16 is smaller than the lateral width of the back sheet 12. Figure 4As shown, most of the hollowing of the leg opening 16 is located on the front piece 11. Different from the appearance of the traditional front piece 11 and the back piece 12 openings being cut at the same time, the structural design of the present technical solution is more in line with the force applied to the product during activities such as human walking; at the same time, the area of ​​the back piece 12 is larger than that of the front piece 11, which also increases the coverage of the main body 1 on the human buttocks, thereby improving the support and wrapping properties.

[0025] In this technical solution, the lateral width of the crotch piece 2 on the rear piece 12 is greater than that of the crotch piece 2 on the front piece 11; that is, the crotch piece 2 is in a dumbbell-shaped structure with different sizes at both ends, and when the body 1 is folded and sealed, the crotch piece 2 on the front piece 11 is located within the coverage of the crotch piece 2 on the rear piece 12. This design increases the overall area of ​​the crotch piece 2, ensuring that the crotch piece 2 has sufficient coverage to fully wrap the female private parts.

[0026] Although the present invention has been specifically demonstrated and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes may be made to the present invention in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims, all of which are within the scope of protection of the present invention.
