The present disclosure relates generally to absorbent articles, and more particularly relates to nursing pads, and related methods for using nursing pads.
Nursing pads are typically worn by nursing mothers to absorb breast milk that has leaked from the mother's breast. The pads are typically applied to the mother's breast Nursing pads are typically worn by nursing mothers to absorb breast milk that has leaked from the mother's breast. The pads are typically applied to the mother's breast and maintained in position by a garment or article of clothing such as a bra. At least some known nursing pads include an adhesive on a surface of the nursing pad that faces away from the mother's breast when applied to the mother's breast. The adhesive adheres to the bra in order to maintain the nursing pad in position during use. However, the nursing pad may still move relative to the mother's breast because the adhesive that adheres the nursing pad to the bra may be inadequate and may lead to the nursing pad bunching up within the bra, causing discomfort and leakage. Additionally, at least some known nursing pads are made with undesirable materials, such as non-organic materials, that may provoke allergic reactions, not allow breathability, may not be absorbent, and may not be biodegradable or compostable. Moreover, at least some known nursing pads are flat and not contoured to the shape of the user's breast. The flat shape of the nursing pad does not allow the nursing pad to conform to the user's breast when the nursing pad is positioned against the breast. Further, the pads do not have a means of securing to the breast or being fixed in place. As a result, there is slippage and leakage.
One aspect of the present disclosure relates to a stick on, peel off disposable nursing pad including an absorbent pad and an adhesive. The absorbent pad defines a first side and a second side and has a contoured shaped configured to correspond to a shape of a user's breast. The adhesive is attached to the second side of the absorbent pad and is configured to adhere the absorbent pad directly to the user's breast.
Another aspect of the present disclosure relates to a nursing pad including an absorbent pad and an adhesive. The absorbent pad defining a first side and a second side and is formed of a plurality of layers of organic cotton. The adhesive may be attached to the second side of the absorbent pad and is configured to adhere the absorbent pad to the user's breast.
Another aspect of the present disclosure relates to a method of using a nursing pad. The method includes providing the nursing pad including an absorbent pad and an adhesive. The adhesive includes an adhesive substance and a backing. The method also includes removing the backing to expose the adhesive substance. The method further includes applying the nursing pad to a user's breast by adhering the adhesive substance to the user's breast.
Yet another aspect of the present disclosure relates to a method of making a nursing pad. The method includes applying an adhesive to a first quilted layer of an absorbent pad. The method also includes applying a backing onto the adhesive to protect the area of the adhesive before use. The method also includes layering at least one additional layer of an absorbent pad on the first quilted layer of an absorbent pad. The method also includes applying a barrier layer on the at least one additional layer of the absorbent pad. The method also includes compressing the first quilted layer of an absorbent pad, the at least one additional layer of an absorbent pad, and the barrier layer together.
The foregoing has outlined rather broadly the features and technical advantages of examples according to the disclosure in order that the detailed description that follows may be better understood. Additional features and advantages will be described hereinafter. The conception and specific examples disclosed may be readily utilized as a basis for modifying or designing other structures for carrying out the same purposes of the present disclosure. Such equivalent constructions do not depart from the spirit and scope of the appended claims. Features which are believed to be characteristic of the concepts disclosed herein, both as to their organization and method of operation, together with associated advantages will be better understood from the following description when considered in connection with the accompanying figures. Each of the figures is provided for the purpose of illustration and description only, and not as a definition of the limits of the claims.
Implementations are disclosed in association with the accompanying drawings in which:
In the illustrated embodiments, the absorbent article 100 includes a nursing pad 100. In alternative embodiments, the absorbent article 100 may be any type of absorbent article including, without limitation, bandages, feminine hygiene products, diapers, sanitary articles, and/or any other article configured to absorb liquid.
In the illustrated embodiment, the nursing pad 100 includes an absorbent pad 102 and an adhesive 104 attached to the absorbent pad 102. The absorbent pad 102 is configured to be attached to a user's breast by the adhesive 104 and to absorb liquid (breast milk) produced or leaked from the user's breast. Specifically, the absorbent pad 102 includes a first side 108 and a second side 106. The adhesive 104 is attached to the first side 108. The user exposes the adhesive 104 and applies the first side 108 of the absorbent pad 102 to the user's breast such that the adhesive 104 maintains the absorbent pad 102 in place on the user's breast. The user can remove the absorbent pad 102 from the user's breast by peeling the absorbent pad 102 away from the user's breast such that the adhesive 104 no long adheres the absorbent pad 102 to the user's breast. Accordingly, the nursing pads 100 described herein enable the absorbent pad 102 to be adhered to a user's breast without additional support from clothing (e.g., bras or other supportive articles of clothing) and improves the absorbency of the absorbent pad 102 by adhering the absorbent pad 102 directly to the user's breast.
The absorbent pad 102 is formed from a plurality of layers (shown and described in
In the illustrated embodiment, the layers of absorbent material each include a layer of absorbent material formed in a quilted pattern on the first side 108 of the absorbent pad 102 to provide breathability and to pull or wick moisture away from the user's breast and maintain the integrity of the adhesive 104. In some embodiments, the layers of absorbent material are formed into a waffle pattern to support the adhesive 104 on the first side 108 of the absorbent pad 102. In some embodiments, the quilted or waffle pattern provides additional support for the adhesive 104 such that the adhesive substance remains on the absorbent pad 102 when the nursing pad 100 is removed from and reapplied to the user's breast. Additionally, in order to reduce leaks, the absorbent pad 102 may include a barrier layer 110 positioned on the second side 106 of the absorbent pad 102. The barrier layer 110 may be formed of various materials configured to act as a vapor barrier, a liquid barrier, and/or a liquid and vapor barrier.
The absorbent pad 102 is formed by compressing the layers of absorbent material and the barrier layer 110 (if included) until the layers from a cohesive absorbent pad 102. Specifically, in the illustrated embodiment, the layers of absorbent material are stacked on the barrier layer 110 (if included) until the predetermined thickness of the absorbent pad 102 is achieved. The layers are then compressed by a compression machine or manually such that the layers from the cohesive absorbent pad 102. In some implementations, the compression machine compresses the layers such that the outer diameter of the absorbent pad 102 has a seal 124 that prevents liquid from escaping the absorbent pad 102. Additionally, the compression machine may cut the layers into the shape of the absorbent pad 102. In alternative embodiments, the layers may be stitched together to form the seal 124 rather than compressed to form the seal 124.
The nursing pad 100 includes the barrier layer 110, a plurality of intermediate layers of absorbent material, and an inner layer to be in contact with the skin of the user. The layers of the nursing pad 100 may include a variety of materials. For example, the barrier layer may be formed of biodegradable vapor barriers. In some implementations, the intermediate layers of absorbent material may include a hydrophilic cotton core formed by layers of the certified organic cotton, or other material, in order to improve the distribution or dispersion of the liquids absorbed by the absorbent pad 102, optimizing the absorption capacity of the nursing pad 100. In some implementations, the inner layer is formed of the quilted certified organic cotton. The hydrophilic cotton core wicks moisture away, reducing clogs that may develop because of stagnant liquid near the user's breast.
As shown in
The adhesive 104 includes an adhesive substance (not shown) attached to the first side 108 of the absorbent pad 102 and a backing 112 selectively attached to the adhesive substance. In the illustrated embodiment, the adhesive substance includes a medical grade adhesive. In alternative embodiments, the adhesive substance may be any type of adhesive that enables the nursing pad 100 to operate as described herein. In another alternative embodiment, the nursing pad 100 may not include the adhesive 104. Rather, the absorbent pad 102 may be maintained on the user's breast with an article of clothing (e.g., a bra).
The backing 112 covers and protects the adhesive substance prior to use to maintain the adhesive substances ability to bond the absorbent pad 102 to the user's breast when not in use. The backing 112 has a shape that corresponds to the shape of the adhesive substance on the first side 108 of the absorbent pad 102. In the illustrated embodiment, the adhesive substance is formed in an adhesive ring and the backing 112 has a corresponding ring shape. In alternative embodiments, the adhesive substance and the backing 112 may have any shape that enables the nursing pad 100 to operate as described herein. In the illustrated embodiment, the backing 112 includes a wax paper covering including a pull tab 114 for removal of the backing 112. In alternative embodiments, the backing 112 may be any type of covering that enables the nursing pad 100 to operate as described herein.
The compressed organic cotton absorbent pad 102 maintains the adhesive substance on the absorbent pad 102 during use. In some implementations, the compressed organic cotton absorbent pad 102 provides a robust substrate that retains the adhesive substance on the absorbent pad 102 so that the absorbent pad 102 may be repeatedly applied to and removed from the user's breast, for example, if a user needs to remove the absorbent pad 102 to nurse. Further, the compressed organic cotton absorbent pad 102 enables the nursing pad 100 to be applied and removed to and from the user's breast multiple times throughout the use of the nursing pad 100 without the adhesive substance adhering to the user's breast.

As shown in
In some implementations, a plurality of nursing pads 100 may be stored and transported in a container. In some examples, the container includes a bag. In alternative embodiments, the container may include any other container including, without limitation, a box or a tube. Additionally, the container may be stored or transported in another container. Moreover, the nursing pads 100 may be individually wrapped in the container. In some embodiments, the container may be configured to store and transport 30 or more nursing pads 100.
Yet another aspect of the present disclosure relates to a method of making a nursing pad. The method includes applying an adhesive to a first quilted layer of an absorbent pad. The adhesive may be applied in a variety of locations on the first quilted layer. For example, in some implementations, the adhesive is applied in a ring or circular shape. The method also includes applying a backing onto the adhesive to protect the area of the adhesive before use. The backing is applied to the area of adhesive that does not contact the first quilted layer. A user can later remove the backing and affix the adhesive to the user's breast during use. In some implementations, the backing may include a pull tab for later removal of the backing from the adhesive. The method also includes layering at least one additional layer of an absorbent pad on the first quilted layer of an absorbent pad. In some implementations, the at least one additional layer may be numerous (e.g., 4-5) layers (e.g., of organic cotton). The method also includes applying a barrier layer on the at least one additional layer of the absorbent pad. In some implementations, the barrier layer may be a vapor barrier or other material that resists diffusion of moisture and keeps the nursing pad from leaking milk. The method also includes compressing the first quilted layer of an absorbent pad, the at least one additional layer of an absorbent pad, and the barrier layer together. The compressing of the first quilted layer of an absorbent pad, the at least one additional layer of an absorbent pad, and the barrier layer may be performed manually or by machine. In some implementations, the first quilted layer of an absorbent pad, the at least one additional layer of an absorbent pad, and the barrier layer together are stitched together (e.g., with thread or nylon). The stitching may occur around the perimeter of the absorbent pad or in other locations.
