Detailed Description

Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. In the following description, a description of technologies that are well known in the art and are not directly related to the present disclosure may be omitted to clearly convey the gist of the present disclosure.

Advantages and features of the present disclosure and methods of accomplishing the same will become apparent by reference to the embodiments of the present disclosure described in detail below with reference to the accompanying drawings. This disclosure may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In the present disclosure, like elements are denoted by like reference numerals.

Throughout the specification, when an element such as a layer, region or substrate is described as being "on," "connected to" or "coupled to" another element, it can be directly on, "connected to" or "coupled to" the other element or intervening one or more other elements may be present therebetween. In contrast, when an element is referred to as being "directly on," "directly connected to" or "directly coupled to" another element, there may be no intervening elements present therebetween.

Although terms such as "first", "second", and "third" may be used herein to describe various elements, components, regions, layers or sections, these elements, components, regions, layers or sections are not limited by these terms. Rather, these terms are only used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, a first element, component, region, layer or section discussed in the examples described herein could be termed a second element, component, region, layer or section without departing from the teachings of the examples.

Spatially relative terms, such as "above," "upper," "lower," and "lower," may be used herein to facilitate describing one element's relationship to another element as shown. Such spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "above" or "upper" relative to other elements would then be "below" or "lower" relative to the other elements. Thus, the term "above" includes both an orientation of above and below, depending on the spatial orientation of the device. The device may be otherwise oriented (e.g., rotated 90 degrees or at other orientations) and the spatially relative terms used herein are to be interpreted accordingly.

Fig. 1 shows an exploded view of the structure of the left half of a mask according to one embodiment of the present application. As shown in fig. 1, the left half of the mask includes an outer layer 101, a first adhesive film layer 102, an intermediate layer 103, a second adhesive film layer 104, and an inner layer 105. It should be understood that the inner and outer in this application are relative to the direction when worn by the user. Specifically, the side close to the face of the user is the inner side of the mask, and the side far away from the face of the user is the outer side.

The outer layer 101 is a one-piece structure and includes a face region for covering the face of a user and an ear loop region for hanging over the ears of the user. The ear loop region can be formed, for example, by mechanical cutting. The outer layer 101 may be constructed of an elastic fabric (e.g., nylon, or a blend of nylon and spandex, such as 70% nylon plus 30% spandex) so that it can fit users of various sizes. The outer layer 101 can be cut freely, whereby the outer layer 101 can hold the edge well even after repeated water washing. Alternatively, the outer layer 101 is made of a material having a waterproof and breathable function. For example, the outer layer 101 may have a structure of warp knitted fabric (Tricot), weft knitted double-sided fabric (Interlock), single jersey (single jersey), or the like. For example, the outer layer 101 may be a nylon, a nylon spandex blend, a pure cotton, a polyester spandex blend, or the like. For example, the outer layer 101 may be treated after finishing with a water repellent aid to achieve a water repellent function.

The inner layer 105 is configured to contact the facial skin of a user. For example, the inner layer 105 may be made of a material having a sterilization and deodorization function. For example, inner layer 105 may be of weft-knit double-faced fabric, single-faced plain knit fabric, or the like. For example, the composition of the inner layer 105 may be nylon, nylon spandex blends, pure cotton, cotton plus modal, and the like. Inner layer 105 may correspond only to the facial area of outer layer 101, thereby reducing the thickness of the earring area of outer layer 101; but is not limited thereto.

The intermediate layer 103 may be composed of a material with protective filtration. For example, the intermediate layer 103 may be composed of polytetrafluoroethylene PTFE, but is not limited thereto. The PTFE used to form the intermediate layer 103 may have a small fiber diameter, for example, may be below 100nm, and have a porosity of up to 85%. One or both sides of the PTFE layer may be covered with a non-woven fabric to collectively form the intermediate layer 103. As with the inner layer 105, the intermediate layer 103 may correspond only to the facial area of the outer layer 101, thereby reducing the thickness of the earring area of the outer layer 101; but is not limited thereto.

The first adhesive film layer 102 is used to bond the outer layer 101 and the intermediate layer 103 together. The second adhesive film layer 104 is used to bond the inner layer 105 and the intermediate layer 103 together. As shown, the first and second adhesive film layers 102 and 104 are disposed only at edge portions of the intermediate layer 103 and/or the inner layer 105 to connect the layers and not necessarily applied to the entire surface of the intermediate layer 103 and/or the inner layer 105. The first and second adhesive film layers 102 and 104 may be formed of, for example, a Polyurethane material, such as Thermoplastic Polyurethanes (TPU), Ester polyurethanes (Ester polyurethanes), and the like.

The right half of the mask has a symmetrical structure with the left half. Therefore, the symmetrical shape of each component of the exploded view shown in fig. 1 is suitable for the right half of the mask, and will not be described in detail herein.

Although a three layer construction (outer, middle and inner) mask is shown, it should be understood that the middle layer 103 is optional and that a seamless mask according to the present application may also be a two layer construction including an outer layer and an inner layer. In the following description, description will be made with reference to a mask of a three-layer structure.

Hereinafter, an exemplary structure of a mask according to the present application will be described in connection with a manufacturing process of the mask.

Fig. 2A shows a schematic view of the material of fig. 1 laminated for bonding and heat pressing to form two half portions of a mask. Fig. 2B shows a schematic view of the material of fig. 2A bonded and heat pressed to form two halves of a mask.

As shown in fig. 2A, the outer layer 101, the first adhesive film layer 102, the intermediate layer 103, the second adhesive film layer 104, and the inner layer 105 of the left and right mask halves are laminated between the hot press plates in this order from the bottom up. The first adhesive film layer 102 and the second adhesive film layer 104 bond the outer layer 101, the intermediate layer 103, and the inner layer 105 together by a heat pressing process, forming a seamless-joined left half portion and a seamless-joined right half portion. It should be understood that in the present application, a "seamless" connection is referred to with respect to a stitched connection by stitches. Because the suture is not sewn through stitches, discomfort caused by contact with the suture thread does not exist at the connection part. Fig. 2B shows an internal structural view of the left and right halves formed by the process of fig. 2A.

FIG. 3 shows a schematic view of the left and right halves of the mask body formed by the conformable heat press shown in FIG. 2A being spliced together.

It should be understood that the left and right halves formed by the conformable heat press shown in fig. 2A are planar structures. After the left half part and the right half part are aligned and overlapped, the redundant seam allowance can be cut off from top to bottom through the ultrasonic cutting die 301 with the preset shape, and meanwhile, the two cut pieces of the left half part and the right half part are spliced together. The masks before and after splicing are shown by structures 302 and 303, respectively, in fig. 3. The shape of the splice and/or the shape of the ultrasonic blade die may be arranged such that the desired 3D structure is formed when the left and right halves are attached to each other. In the spliced structure, the outer layers of the left half and the right half are flush with each other.

Fig. 4 is a schematic view showing a decorative material covering the mask body formed by splicing. As shown in fig. 4, the decorative material 401 is covered on the joint of the left half and the right half, and the mask body 402 with the decorative material 401 attached thereto is placed on a shaping mold 403 for hot press shaping, so that the decorative material 401 is shaped at the joint to obtain the final mask. Trim material 401 is preferably strip-shaped. The trim material 401 may be, for example, a trim adhesive film, or may be another material attached by an adhesive. For example, the decorative material 401 may also be a fabric material, a microfiber material, a leather material, or a plastic sheet with a good supporting and protecting effect. The finishing material 401 may be joined to the splice of the left and right halves, for example, by ultrasonic welding. The finishing material 401 may also be an adhesive tape or fabric bonded to the outer layer by heat pressing. The shape and color of trim material 401 may have any design features as long as it covers the splice. The finishing material 401 may function to protect the splice and prevent the splice from breaking. The finishing material 401 may be formed of, for example, polyurethane PU, thermoplastic polyurethane TPU.

It should be understood that although the decorative material is shown as being disposed at the splices on the outside of the mask, the decorative material may alternatively be disposed at the splices on the inside of the mask, or at the splices on the inside surface of the outer layer.

Fig. 5A, 5B and 5C show front, bottom and cross-sectional views, respectively, of a mask according to the present application. Fig. 6 shows a schematic view of a user wearing a mask.

As shown in fig. 5A, there is a trim material 401 at the splice of the left and right halves. On the one hand, the decorative material 401 may seal the ultrasonic splice to ensure protection; on the other hand, the decorative material 401 can increase the support of the three-dimensional effect and keep the good three-dimensional effect, so that the three-dimensional shape of the mask is not easy to collapse and deform.

As shown in fig. 5B, since the layers of the mask are joined together seamlessly, the mask does not come into contact with foreign matter such as a sewing thread when worn by a user, and thus comfortable wearing feeling can be ensured.

Fig. 5C shows a cross-sectional view along line a-a of fig. 5B. As shown, an outer layer 101, a first adhesive film layer 102 (only at the edge), an intermediate layer 103, a second adhesive film layer 104 (only at the edge), and an inner layer 105 are laminated in this order from the outside to the inside. The above layers are made of a material that can be repeatedly washed with water, and are materials that can withstand the high temperatures of hot press molding.

As shown in fig. 6, when a user wears the mask according to the present application, a certain space is formed between the mouth of the user and the mask due to the three-dimensional shape of the mask, thereby effectively improving comfort and maintaining a good breathing feeling. The ornamental material of concatenation department can seal the concatenation position in order to ensure the protection nature to the support nature of multiplicable stereoeffect makes the gauze mask can keep better stereoeffect, is difficult to flat collapse or warp.

Comfort, appearance and protection are improved due to the seamless connection between the components (as opposed to sewing). Because the outer layer is freely cut and the inner layer and the middle layer do not extend to the edge of the outer layer, the edge of the mask does not bring uncomfortable feeling to the skin of a wearer.

Fig. 7 shows a flowchart of a mask manufacturing method according to an exemplary embodiment.

In step 701, the left and right halves of the mask are formed by seamlessly joining the inner and outer layers, respectively. The materials and the joining means of the inner and outer layers have been described above and are therefore not described in detail here.

Optionally, an intermediate layer for filtration is further provided in addition to the inner layer and the outer layer. In the case of having the intermediate layer, the left half and the right half of the mask are formed by seamlessly joining the inner layer and the outer layer, respectively, to the intermediate layer. The materials and the bonding means of the intermediate layer are also described above and will therefore not be described in further detail here.

At step 702, the formed left and right halves are seamlessly spliced to form the desired volumetric shape. For example, the left half and the right half can be seamlessly spliced by means of ultrasonic cutting to form the desired three-dimensional shape.

Optionally, at step 703, a finishing material may be covered at the splice of the left and right halves to ensure protection and to increase the support of the stereoscopic effect.

It should be understood that the technical features described with reference to fig. 1 to 6 are all applicable to the method of fig. 7. Therefore, the respective features already described are not described repeatedly.
