Description

Technical Field

[0001] The present invention relates to the technical field of sanitary products, and particularly relates to a multi-level diversion light incontinence towel and its production process. Background Art

[0002] Light incontinence is common in middle-aged and elderly people and postpartum women. Under some circumstances where the intra-abdominal pressure increases, urine flows out of the urethra uncontrollably, resulting in odor and dampness, thus affecting normal life. A light incontinence towel is a disposable absorbent sanitary product for the group with mild urinary incontinence. The core is mostly composed of wood pulp and highly absorbent polymers for urine. When in use, it is placed in the underwear like a sanitary napkin. The light incontinence towel is light, unobtrusive and portable, not as heavy as adult diapers, and is suitable for the mild urinary incontinence population with urine leakage problems at present.

[0003] When the instantaneous urine outflow volume is too large, the existing light incontinence towels are difficult to absorb all the urine in a short time. Since three-dimensional side guards are generally provided on both sides of the light incontinence towel, urine generally does not leak from the side. However, when urine leaks, it mainly concentrates on the front side. Coupled with the stronger fluidity of urine, it is easy for urine to exceed the safety zone on the front side of the light incontinence towel, resulting in front leakage. In addition, problems such as slow urine absorption speed and poor air permeability of the existing light incontinence towels will also cause the contact part to be stuffy and prone to bacteria growth, thus forming odor and even causing physiological diseases, affecting the normal life and social interaction of the light incontinence population, and even causing psychological pressure to them.

[0004] At present, disposable absorbent articles such as sanitary napkins and light incontinence towels have a liquid-permeable upper layer, a liquid-impermeable lower layer, and an absorbent layer for liquid absorption and retention between the upper layer and the lower layer. In addition, in order to make the longitudinal sides thereof have leak-proof properties, standing leak-proof components are provided on both sides of the disposable absorbent article.

[0005] In common absorbent articles, standing leak-proof components are provided on both longitudinal sides. The leak-proof component is composed of a sheet material and an elastic member. The elastic member is wrapped by the sheet material. The longitudinal ends of the sheet material are joined to the upper layer or the lower layer. The leak-proof component stands up by the retraction of the elastic member and plays a leak-proof role. However, the above-mentioned existing leak-proof component presents a sheet shape after standing up, and the elastic member separates the sheet material from contacting the human body. During use, it rubs against the human body. The slender elastic member separates the sheet material from linearly contacting and rubbing against the human body, which is easy to damage the skin. The leak-proof component is sheet-shaped and stands up relying on the elasticity of the elastic member. In the case of being subjected to a lateral force, the standing stability of the leak-proof component is poor and it is easy to deform, with the risk of causing side leakage.

[0006] Common absorbent articles have a liquid-permeable upper layer, a liquid-impermeable lower layer, a liquid-absorbing and retaining absorbent layer between the upper layer and the lower layer, and a diversion layer between the upper layer and the absorbent layer. In addition, leak-proof components with erectability are provided on both sides. Since urine is different from menstrual blood, menstrual blood has a certain viscosity and its flow rate is relatively slow, while urine has little viscosity and is more fluid. When the instantaneous urine outflow is too large, the existing light incontinence pads are difficult to absorb all the urine in a short time, resulting in urine easily exceeding the safety zone in the front of the light incontinence pad and causing front leakage. Summary of the Invention

[0007] The present invention provides a multi-level diversion light incontinence pad and its production process to solve the technical problems in the prior art.

[0008] To solve the above problems, the multi-level diversion light incontinence pad provided by the present invention adopts the following technical solutions: including a longitudinally arranged absorbent layer, a surface layer located above the absorbent layer, and a back layer located below the absorbent layer.

[0009] A fan-shaped tail member for preventing front leakage is provided between the absorbent layer and the back layer, and the transverse width of the fan-shaped tail member is greater than that of the absorbent layer.

[0010] A diversion layer for drainage is provided between the absorbent layer and the surface layer.

[0011] The multi-level diversion light incontinence pad is provided with embossing lines for connecting the absorbent layer, the surface layer and the back layer. The embossing lines compress the absorbent layer in the thickness direction. The embossing lines include inner embossing lines and outer embossing lines. Both the inner embossing lines and the outer embossing lines are annular. A raised barrier ring is formed between the inner embossing lines and the outer embossing lines, and a receiving cavity for storing liquid and reducing liquid leakage is formed inside the barrier ring.

[0012] As a further improvement, a blue cotton layer is provided between the diversion layer and the surface layer. The outer edge of the blue cotton layer extends between the inner embossing line and the outer embossing line. The inner embossing line compresses the product in the thickness direction, and the edge of the blue cotton layer warps upward under pressure. The edge position of the blue cotton layer does not closely fit the absorbent layer.

[0013] As a further improvement, the fan-shaped tail member is provided on the front side of the multi-level diversion light incontinence pad, so that when in use, the fan-shaped tail member cooperates with the front side part of the female private part to form a funnel shape for draining urine and avoiding front leakage.

[0014] As a further improvement, leak-proof components for preventing urine side leakage are provided on both the left and right sides of the surface layer. The leak-proof components include an outer covering layer and an elastic member provided in the covering layer. The elastic member includes a buffer layer and a plurality of elastic members wrapped in the buffer layer.

[0015] As a further improvement, at least three elastic members are provided, at least two elastic members are provided on the side of the inner side of the light incontinence towel close to the inner side of the outer covering layer, and at least one elastic member is provided on the side of the outer side of the light incontinence towel close to the inner side of the outer covering layer.

[0016] As a further improvement, four elastic members are provided, three elastic members are provided on the side of the inner side of the light incontinence towel close to the inner side of the outer covering layer, and one elastic member is provided on the side of the outer side of the light incontinence towel close to the inner side of the outer covering layer.

[0017] The present invention also provides a production process for a multi-level diversion light incontinence towel, including the following steps:

[0018] S1. Preparation of the absorption layer; the core layer of the absorption layer is formed in the forming grinding wheel, and the lower covering layer of the absorption layer receives the core layer and covers the upper covering layer to obtain the absorption layer;

[0019] S2. Lamination of the back layer, the fan tail member and the absorption layer;

[0020] S3. Preparation of the leak-proof component and lamination with the surface layer;

[0021] S4. Lamination of the diversion layer, the blue cotton layer and the absorption layer; the diversion layer and the blue cotton layer are cut, the diversion layer is laminated on the upper side of the absorption layer, and the cut blue cotton layer is laminated on the upper side of the diversion layer;

[0022] S5. The back layer, the fan tail member, the absorption layer, the diversion layer, the blue cotton layer, the surface layer and the leak-proof component are sequentially arranged from bottom to top to form the light incontinence towel, and the inner embossing line and the outer embossing line press down on the light incontinence towel to form diversion embossing.

[0023] As a further improvement, in step S2, the back layer is laminated with the fan tail member cut into a fan shape and is laminated with the lower surface of the absorption layer, wherein the fan tail member is in the front end area of the absorption layer and in the front 1 / 2 part of the light incontinence towel.

[0024] As a further improvement, in step S3, the buffer layer of the leak-proof component is conveyed in the unfolded state, the elastic member is intermittently joined to the buffer layer in the stretched state, and the buffer layer is folded to form a double-layer elastic member. The elastic member is intermittently joined to the outer covering layer conveyed in the unfolded state in the stretched state, and one side of the outer covering layer is coated with glue and adhered to the other side of the outer covering layer, thereby forming a hollow structure wrapping the elastic member;

[0025] After the leak-proof component is formed, the bottom end of the leak-proof component is joined to the surface layer.

[0026] The beneficial effects of the above technical solutions of the present invention are as follows:

[0027] 1. By providing inner embossed lines and outer embossed lines, a raised barrier ring is formed on the upper surface of the absorption layer, making the contact part of this product with the female private parts present a "concave" shape. The concave area can ensure that the product does not closely contact the private parts, effectively reducing the discomfort caused by the friction between the product and the private parts when the user walks, which conforms to ergonomics.

[0028] A receiving cavity is formed inside the barrier ring. The receiving cavity can hold urine, reducing the diffusion of urine to the surrounding area. The urine in the receiving cavity penetrates downward and is quickly guided by the diversion layer to the surrounding absorption layer.

[0029] Compressed by the inner embossed lines and outer embossed lines, the surface layer presses downward on the barrier ring, making the density of the top of the barrier ring greater than that of the bottom of the barrier ring; when urine penetrates, it will preferentially penetrate into the fluffy area of the absorption layer, and the urine will finally penetrate into the denser top of the barrier ring. In this way, it can ensure that the top of the barrier ring in direct contact with the skin can remain dry for a long time.

[0030] 2. The fibers of the blue cotton layer are finer than those of the diversion layer. When urine flows onto the blue cotton layer, it can be quickly conducted to the diversion layer and absorbed by the absorption layer, effectively keeping the female private parts dry.

[0031] The blue cotton layer is arranged between the inner embossed lines and the outer embossed lines. The inner embossed lines compress the product in the thickness direction, and the edges of the blue cotton layer tilt upward under the pressure. The edge positions of the blue cotton layer do not closely fit the absorption layer. This elevated area can isolate the female private parts from this light incontinence towel to a certain extent during use, keeping the female private parts dry.

[0032] 3. A fan-shaped tail member is arranged on the front side of the absorption layer. The large fan head conforms to the shape of the front side of the female private parts, providing better coverage of the body during use. During use, a funnel shape is formed between the large fan head and the user's skin, buffering the urine and concentrating the urine to be drained quickly to the absorption layer for absorption, thereby reducing the situation of urine leakage in front due to excessive instantaneous urine outflow.

[0033] 4. In the leak-proof component, the buffer layer is folded and wrapped around the elastic member to form an elastic component. The two ends of the elastic component are fixed to the outer wrapping layer. With this setting, only the two ends of the elastic component and the outer wrapping layer are joined by an adhesive. On the one hand, this can reduce the use of adhesives. On the other hand, after not using the glue in the middle position, the outer wrapping layer will not show a locally hard situation, and it has a higher softness, thus obtaining a leak-proof component with higher comfort;

[0034] The left and right sides of the outer wrapping layer are joined to form a hollow structure. The elastic body stretches elastically in the hollow structure, making the leak-proof component form an arch. The contact surface between the skin and the leak-proof component is on the arc surface, avoiding the serrated edges of the sheet-shaped leak-proof component of the above-mentioned ordinary absorbent articles, and reducing the risk of skin abrasion caused by friction.

[0035] In addition, by adjusting the distribution of the elastic members, the situation of relatively large local tensile force of the three-dimensional crotch guard is reduced; at the same time, an elastic member is separately provided on one side far from the root of the thigh. When in use, the separately provided elastic member is stretched relatively longer, so that the tensile force generated by this independent elastic member is neither too large nor can the outer covering layer fit better with the skin, thereby realizing the reduction of the risk of urine leakage while improving the comfort level.

[0036] 5. By measures such as accelerating urine absorption and reducing side leakage, the present invention can reduce the growth of bacteria and the generation of odors, thereby reducing the impact of mild incontinence on the normal life and social interaction of the mild incontinence population, and even the situation of causing psychological pressure to them, and meeting the social needs and respect needs of the mild incontinence population.

[0047] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

[0048] Light incontinence pads are similar to sanitary napkins in some aspects and different in others. Most existing light incontinence pads have structures similar to sanitary napkins. However, compared with menstrual blood, urine has greater fluidity, resulting in a relatively higher risk of side leakage in existing light incontinence pads.

[0049] Regarding the above problems, the present invention reduces the risk of urine side leakage by adjusting the structure of the light incontinence pad from two dimensions: improving the urine absorption speed and reducing urine overflow.

[0050] Combined with ergonomics, the concave part of the barrier ring can ensure that the product does not closely contact the private parts, effectively reducing the discomfort caused by the friction between the product and the private parts when the user moves. At the same time, it can play a certain role in blocking urine and reducing the spread of urine to the surrounding area.

[0051] In addition, adopting the idea of multi-gradient drainage, by setting structures such as a barrier ring, a blue cotton layer, and a fan tail member, during urine absorption, each gradient will play a role in draining urine. The cooperation between the gradients can quickly guide urine from the surface of the product to the inside and from the local area to the whole, ensuring the absorption speed and the dryness of the product, and increasing the utilization rate of the product core and the absorption capacity of the product.

[0052] The leak-proof component adopts a design of a hollow tunnel structure, and an outer cladding layer is arranged outside the elastic member. This structure can avoid the appearance of serrated edges, reducing the risk of skin abrasion caused by friction, thereby improving the wearing comfort and making the leak-proof component better fit the skin. In addition, the elastic member is only coated with glue at the front and rear ends and connected to the outer cladding layer, further improving the softness of the outer cladding layer.

[0053] The elastic members of the leak-proof component adopt a dispersed design. The dispersed design does not evenly distribute the elastic members within the outer covering layer, but combines the force-bearing situation to distribute the elastic members on the left and right sides within the outer covering layer. Taking four elastic members as an example, three of them are arranged on the side close to the skin within the outer covering layer (i.e., the inner side close to the light incontinence towel), and the other elastic member is arranged on the other side within the outer covering layer. With this arrangement, when in use, the tensile force on the side of the outer covering layer close to the skin is reduced. Moreover, after changing from four elastic members to three elastic members, the intervals between the three elastic members are relatively farther apart, avoiding the problem of excessive force concentration and improving the wearing comfort. The single elastic member independently arranged on the other side can stretch the outer covering layer outward during use, improving the fit between the outer covering layer and the skin, reducing the gap between the outer covering layer and the skin, and thus improving the side leakage situation. Since the independently arranged elastic member is close to the outer side of the light incontinence towel, its tensile deformation is relatively larger when worn. Therefore, generally only one elastic member is independently arranged within the outer covering layer to avoid excessive tensile force affecting the comfort level.

[0054] When the elastic member is adhered inside the outer covering layer, it is in a stretched state. After the processing is completed, the elastic member shrinks, and the leak-proof component generates a structure similar to an arch, which can well resist the lateral force applied to the leak-proof component, and its standing property is better, effectively preventing the occurrence of side leakage.

[0055] Although the improved leak-proof component has a better anti-side leakage effect, the raw material cost increases, and the processing difficulty is greater. If the production problems are not solved, it will only make the product difficult to promote.

[0056] Firstly, it is the elastic member. In the present invention, the elastic member adopts a semi-open structure, that is, after the elastic member is adhered to the buffer layer, the buffer layer is directly folded in half to wrap the elastic member to form the elastic member. In this way, compared with the fully enclosed elastic member, the processing difficulty and cost of the semi-open elastic member are relatively lower. Moreover, since the elastic member is arranged inside the outer covering layer, the semi-open elastic member will not rub the skin due to its edges and corners.

[0057] The outer covering layer adopts strip-shaped cotton sheets or non-woven fabric sheets. After the front and rear ends are distributed and adhered to the elastic member, the left and right sides of the outer covering layer are adhered to form a hollow-structured outer covering layer. By this method, firstly, the processing difficulty is low. The elastic member is placed on the unfolded outer covering layer, and after applying glue to both ends to join the elastic member, the outer covering layer is folded over. These actions are relatively simple and can achieve mass production. At the same time, only applying glue to the front and rear ends not only reduces the amount of glue used and the production cost, but also in the middle part of the leak-proof component, the outer covering layer is not coated with glue and has no direct connection with the elastic member, making the outer covering layer relatively softer.

[0058] By adopting the above production process, the relative increase in the raw material cost of the leak-proof component is relatively small, the processing difficulty is low, and the processing procedures are not increased too much, thus laying a foundation for the mass production and market launch of this light incontinence towel.

[0059] After introducing the basic principles of the present invention, various non-limiting embodiments of the present invention will be specifically introduced below. Any element quantity in the drawings is for illustration rather than limitation, and any naming is only for distinction without any limiting meaning.

[0060] Below, with reference to several representative embodiments of the present invention, the principles and spirit of the present invention will be elaborated in detail.

[0061] Embodiment 1 of the multi-level diversion light incontinence towel provided by the present invention:

[0062] As Figures 3 - 5 shown, the multi-level diversion light incontinence towel includes a longitudinally arranged absorption layer 6, a surface layer 1 located above the absorption layer 6, and a back layer 8 located below the absorption layer 6.

[0063] A fan-shaped tail member 7 for preventing front leakage is provided between the absorption layer 6 and the back layer 8. The fan-shaped tail member 7 has a transverse width greater than that of the absorption layer 6; the fan-shaped tail member 7 includes a cotton core and a superabsorbent polymer (SAP) filled in the cotton core. The wider fan-shaped structure enables the fan-shaped tail member 7 to cooperate with the front side part of the female private parts to form a funnel shape during use, guiding urine to avoid front leakage.

[0064] A diversion layer 5 for guiding is provided between the absorption layer 6 and the surface layer 1. The diversion layer 5 is used to divert urine to the front and rear ends of the absorption layer 6.

[0065] The multi-level diversion light incontinence towel is provided with embossing lines for connecting the absorption layer 6, the surface layer 1, and the back layer 8. The embossing lines compress the absorption layer 6 in the thickness direction. The embossing lines include inner embossing lines and outer embossing lines. Both the inner embossing lines and the outer embossing lines are annular. A raised barrier ring 3 is formed between the inner embossing lines and the outer embossing lines. An accommodation cavity for storing liquid and reducing liquid leakage is formed inside the barrier ring 3. Figure 5 In the figure, L1 and L2 are the outer embossing line and the inner embossing line respectively. In other embodiments, embossing strips for compressing the absorption layer 6 in the thickness direction are further provided inside the barrier ring 3. Figure 5 In the figure, L3 is the embossing strip. The embossing strip can be a continuous line structure or a plurality of dot-like structures arranged at intervals. The embossing strip can reduce the thickness of the absorption layer 6 inside the barrier ring 3 and reduce the contact between the female private parts and this product. At the same time, a small annular protrusion is formed between the inner embossing line and the embossing strip, which is beneficial to increasing the contact area between urine and surface layers such as the blue cotton layer 4, accelerating the downward diversion of urine; when the urine volume is small, the small annular protrusion can also play a role in blocking urine and reducing urine flow.

[0066] By arranging small cotton cores at positions corresponding to the barrier ring 3 on the absorption layer 6, the height of the protrusion of the barrier ring 3 can be adjusted.

[0067] As Figure 5 shown, a blue cotton layer 4 is provided between the diversion layer 5 and the surface layer 1. The denier of the blue cotton is 1.5 - 7D. The outer edge of the blue cotton layer 4 extends between the inner embossed line and the outer embossed line. The inner embossed line compresses the product in the thickness direction. The edge of the blue cotton layer 4 warps upward under pressure, and the edge position of the blue cotton layer 4 does not closely fit with the absorbent layer 6.

[0068] Leak - proof components 2 for preventing urine leakage are provided on both the left and right sides of the surface layer 1. The leak - proof component 2 includes an outer cladding layer 203 and an elastic member provided inside the cladding layer. The elastic member includes a buffer layer 202 and a plurality of elastic members 201 wrapped inside the buffer layer 202.

[0069] As Figure 1 and Figure 2 shown, the production process of the existing leak - proof component 2 includes the following steps:

[0070] S1: Conveying process

[0071] The sheet material 9 is continuously conveyed at intervals;

[0072] S2: Elastic member 201 setting process

[0073] The elastic members 201 are set on one side of the sheet material 9 in a stretched state, and there are multiple elastic members 201;

[0074] S3: Folding process

[0075] The sheet material 9 is folded in half to wrap the elastic member, forming an elastic body with a two - layer structure;

[0076] S4: Flipping process

[0077] The elastic body with a double - layer structure is flipped upward and outward to form an elastic body with a four - layer structure on the inner side and a double - layer structure on the outer side;

[0078] S5: The formed elastic body is compounded above the surface layer 1 and the bottom film.

[0079] An adhesive is applied between the sheet materials 9 of the existing leak - proof component 2. The leak - proof component 2 is relatively hard, and the touch feeling when contacting the skin is poor; the formed leak - proof component 2 is sheet - shaped. The top of the sheet - shaped component has a linear contact with the human body and has serrated wrinkles, which are easy to damage the skin and are prone to deformation, and the stability is relatively poor.

[0080] As Figure 6 and Figure 7 shown, this embodiment discloses a production process of a multi - level diversion light incontinence towel, including the following steps:

[0081] S1. Preparation of the absorption layer 6; the core layer 601 of the absorption layer 6 in the forming grinding wheel is formed, and the lower cladding layer 602 of the absorption layer 6 receives the core layer 601 and is covered with the upper cladding layer 603 to obtain the absorption layer 6;

[0082] S2. Lamination of the back layer 8, the fan tail member 7 and the absorption layer 6; the back layer 8 is laminated with the fan tail member 7 cut into a fan shape and is also laminated with the lower surface of the absorption layer 6, where the fan tail member 7 is in the front region of the absorption layer 6 and in the front 1 / 2 part of the light incontinence towel;

[0083] S3. Preparation of the leak-proof component 2 and lamination with the surface layer 1; the buffer layer 202 of the leak-proof component 2 is conveyed in the unfolded state, and the elastic member 201 is intermittently joined to the buffer layer 202 in the stretched state;

[0084] And the buffer layer 202 is folded in half to form an elastic member with a double-layer structure, and the elastic member is intermittently joined to the outer cladding layer 203 being conveyed in the unfolded state in the stretched state, and this joining point is the first joining end 204

[0085] One side of the outer cladding layer 203 is coated with glue and adhered to the other side of the outer cladding layer 203, and this joining point is the second joining end 205, thereby forming a hollow structure that wraps the elastic member;

[0086] After the leak-proof component 2 is formed, the bottom end of the leak-proof component 2 is joined to the surface layer 1 to form the third joining end 206 and the fourth joining end 207.

[0087] S4. Lamination of the diversion layer 5, the blue cotton layer 4 and the absorption layer 6; the diversion layer 5 and the blue cotton layer 4 are cut, the diversion layer 5 is laminated on the upper side of the absorption layer 6, and the blue cotton layer 4 cut into a ring shape is laminated on the upper side of the diversion layer 5;

[0088] S5. The back layer 8, the fan tail member 7, the absorption layer 6, the diversion layer 5, the blue cotton layer 4, the surface layer 1 and the leak-proof component 2 are sequentially arranged from bottom to top to form a light incontinence towel, and the inner embossing lines and the outer embossing lines press down on the light incontinence towel to form diversion embossing.

[0089] Example 2 of the multi-level diversion light incontinence towel provided by the present invention:

[0090] The main difference from Example 1 is that:

[0091] In this embodiment, there are four elastic members. Three elastic members are provided on the side of the inner side of the outer covering layer close to the inner side of the light incontinence towel, and one elastic member is provided on the side of the outer covering layer close to the outer side of the light incontinence towel. During use, the three elastic members close to the inner side of the light incontinence towel are close to the root of the thigh, and the amount of deformation is relatively small, so that excessive pulling force will not be generated. Moreover, after changing to three elastic members, the interval is larger, avoiding excessive concentration of the pulling force, and the comfort level is also improved. The other elastic member is far from the root of the thigh, and its amount of deformation is relatively larger. Therefore, one elastic member can also generate sufficient pulling force, increasing the contact area between the outer covering layer and the human skin, better fitting the outer covering layer to the human skin, and reducing the situation of side leakage. At the same time, this independently provided elastic member can stretch the light incontinence towel outwards. To a certain extent, it can reduce the situation of wrinkles on the light incontinence towel. If there are wrinkles on the light incontinence towel, it will lead to a reduction in the absorption area, which is not conducive to the rapid absorption of urine or menstrual blood.

[0092] Although this specification has shown and described multiple embodiments of the present invention, it is obvious to those skilled in the art that such embodiments are provided only by way of example. Those skilled in the art will think of many changes, alterations, and alternative ways without departing from the spirit and concept of the present invention. It should be understood that various alternative solutions of the embodiments of the present invention described herein can be adopted in the process of practicing the present invention. The appended claims are intended to define the protection scope of the present invention, and thus cover the module compositions, equivalents, or alternative solutions within the protection scope of these claims.
