A directional flow embossed pattern care pad

Abstract

This utility model relates to the field of nursing pad technology and discloses a directional flow-guiding embossed nursing pad. The upper surface of its absorbent layer is provided with flow-guiding embossed grooves. The flow-guiding embossed grooves include several parallel first oblique embossed grooves and several parallel second oblique embossed grooves. The first oblique embossed grooves and the second oblique embossed grooves form an obtuse angle and an acute angle. The obtuse angle faces the long side of the nursing pad, and the acute angle faces the short side of the nursing pad. By utilizing the different resistances of the obtuse angle and the acute angle between the flow-guiding embossed grooves to the liquid, the obtuse angle inhibits the flow, while the acute angle diffuses the flow. This makes the liquid flow velocity in the length direction of the nursing pad greater than the liquid flow velocity in the width direction, so that the liquid can diffuse relatively faster in the length direction of the nursing pad, thereby improving the overall utilization rate of the nursing pad and reducing or avoiding liquid leakage.

Description

Technical Field

[0001] This utility model relates to the field of nursing pad technology, and in particular to a directional flow embossed nursing pad. Background Technology

[0002] Nursing pads are disposable hygiene products. Depending on the user group, nursing pads can be divided into baby nursing pads, maternity nursing pads, and adult nursing pads. They are mainly used in hospital surgeries, gynecological examinations, maternal care, infant care, incontinence of paralyzed patients, and during menstruation. Baby nursing pads are mainly used for newborns and are primarily for absorbing urine. Nursing pads are meant to be laid flat. Although nursing pads can be purchased in different sizes according to needs, in actual use, when the liquid flow rate and velocity are too high, it is easy to cause leakage.

[0003] The applicant conducted sampling tests and research on existing nursing pads and found that liquid leakage from existing nursing pads all occurred along the long side, and the overall utilization rate of the nursing pads was generally low, indicating room for improvement. In view of this, the applicant innovatively designed the directional flow embossed pattern nursing pad of this application. Utility Model Content

[0004] The purpose of this invention is to provide a directional embossed pattern nursing pad, which improves the overall utilization rate of the nursing pad through directional embossed pattern design, thereby reducing or avoiding liquid leakage.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A directional flow-guiding embossed patterned nursing pad includes an absorbent layer. The upper surface of the absorbent layer is provided with flow-guiding embossed grooves, which include several parallel first oblique embossed grooves and several parallel second oblique embossed grooves. The upper surface of the absorbent layer forms parallelogram-shaped protrusions between the flow-guiding embossed grooves. The first and second oblique embossed grooves form an obtuse angle and an acute angle, with the obtuse angle pointing towards the long side of the nursing pad and the acute angle pointing towards the short side. By utilizing the different resistances of the obtuse and acute angles between the flow-guiding embossed grooves to the liquid, and by utilizing the inhibition of the obtuse angle and the diffusion of the acute angle, the liquid flow velocity along the length of the nursing pad is greater than the liquid flow velocity along the width. This allows the liquid to diffuse relatively faster along the length of the nursing pad, thereby improving the overall utilization rate of the nursing pad and reducing or avoiding liquid leakage.

[0007] Preferably, the obtuse angle ranges from 100° to 170°, and the acute angle ranges from 10° to 80°. This angle range effectively controls the diffusion speed and area of ​​the liquid in both the length and width directions, improving the overall utilization rate of the nursing pad.

[0008] More preferably, the width of the flow-guiding embossing groove is 0.5-3 mm, and the depth is 1-3 mm. This allows the liquid to have a better diffusion and absorption rate on the absorbent layer, reducing the time it takes for liquid to accumulate on the surface of the nursing pad.

[0009] To further improve the liquid diffusion and absorption rate, the side length of the protrusion should preferably be 5-15mm, and more preferably a rhombus shape with a side length of 10mm, which can reduce the liquid accumulation time by 1-2 seconds.

[0010] In a further preferred embodiment, the compacted area of ​​the absorbent layer is 10%-20% of the total absorbent layer area. This proportion of compacted area can effectively ensure the softness of the pad while improving its utilization rate and reducing or preventing liquid leakage, thus avoiding an unpleasant user experience caused by a hard feel due to high embossing density.

[0011] This utility model has a simple structure, is easy to produce, is highly practical, and has good performance, making it worthy of widespread promotion and use. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Example

[0018] See Figure 1-3 A directional flow-guiding embossed patterned nursing pad includes an absorbent layer 3, an outer covering layer 2, a surface layer 1 and a leak-proof layer 4 respectively on the top and bottom of the covering layer 2, the surface layer 1 being made of non-woven fabric, preferably hot-air non-woven fabric; the covering layer 2 being made of wet-strength paper, which can still maintain a certain strength when damp or soaked in water; the covering layer 2 is divided into upper and lower layers, the upper wet-strength paper is laid flat on the top of the absorbent layer 3, and the lower wet-strength paper covers the absorbent layer 3, and the leak-proof layer 4 is made of PE film.

[0019] The upper surface of the absorbent layer 3 is provided with a flow-guiding embossed groove 3-1. The width of the flow-guiding embossed groove 3-1 is preferably 0.5-3mm, and the depth is preferably 1-3mm. The compacted area of ​​the absorbent layer 3 is 10%-20% of the absorbent layer area to ensure the softness of the nursing pad. The flow-guiding embossed groove 3-1 includes several parallel first oblique embossed grooves 3-1-1 and several parallel second oblique embossed grooves 3-1-2. The upper surface of the absorbent layer 3 forms parallelogram-shaped protrusions 3-2 between the flow-guiding embossed grooves 3-1. The side length of the protrusions is preferably 5-15mm. The first oblique embossed grooves 3-1-1 and the second oblique embossed grooves 3-1-2 form an obtuse angle and an acute angle. The obtuse angle ranges from 100° to 170°, and the acute angle ranges from 10° to 80°. The obtuse angle is directed toward the long side of the nursing pad, and the acute angle is directed toward the short side of the nursing pad.

[0020] In this embodiment, a preferred solution is adopted for a 300mm x 450mm nursing pad. The flow-guiding embossing groove 3-1 is formed into a rhombus with a side length of 10mm. The angle of the obtuse angle is 120° and the angle of the acute angle is 60°. The width of the flow-guiding embossing groove 3-1 is 1mm and the depth is 2mm.

[0021] During production, the absorption layer 3 is compacted by a light roller, and then hot-pressed by an embossing roller with the corresponding embossing groove 3-1 pattern to form the embossing groove 3-1, and then combined with other layers.

[0022] By using the suppression effect of obtuse angles and the diffusion effect of acute angles, the liquid flow velocity in the length direction of the flow-guiding embossing groove 3-1 on the nursing pad is greater than the liquid flow velocity in the width direction. This allows for more efficient use of the length direction of the nursing pad, improves the overall utilization rate of the nursing pad, absorbs and stores more liquid, and reduces or avoids liquid leakage.

[0023] The nursing pads in the above embodiments have a soft feel, and the overall utilization rate of the nursing pads can be increased by 30%-40%.

[0024] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
