Abstract

A method for making a mask body of a face mask with supporting strips has the following steps: connecting at least one supporting strip (50) to an interior layer (10) to jointly form a pre-connection portion, and then connecting an exterior layer (30) and a middle layer (20) to the pre-connection portion to make a margin of the exterior layer (30), a margin of the middle layer (20), and a margin of the interior layer (10) connected mutually. The filtering effect of the mask body of the present invention is free from being affected by the pressure marks during connecting, which significantly promotes protection effect of the mask body.

Description

MASK BODY OF FACE MASK WITH SUPPORTING STRIPS AND METHOD FOR MAKING THE SAME Field of the Invention
The present invention relates to a face mask with supporting strips and a method for making said face mask.
Description of Related Art
With reference to Fig. 18, in order to promote comfort for wearing a face mask, a conventional face mask has a mask body and a supporting strip 91 deployed on the mask body to make the mask body bent and curved forward. Consequently, a certain space is formed between the mask body and a nose and a mouth of a wearer to prevent the mask body from repeatedly contacting and departing from the skin of the wearer’s face and causing discomfort of the wearer.
However, a conventional method for producing the conventional face mask has a serious defect. Specifically, the mask body of the conventional face mask has three layers. The three layers respectively are an absorbent layer, an impermeable layer, and a filter layer disposed from inside out. The absorbent layer is configured to absorb saliva, sweat, and breath vapor of the wearer. The impermeable layer is configured to prevent droplet from permeating the mask body.
A traditional face mask without any supporting strip is made by abovementioned three-layer fabric plied together and compressed by a rolling ultrasonic welding wheel. Margins of the three layers are fused together to form the mask body.
Nevertheless, in the method for producing the conventional face mask, the supporting strip is directly deployed between two of the layers before welding. Then the ultrasonic welding wheel rolls above and below the supporting strip for fusion and connection and to fix a position of the supporting strip. However, in addition to fusing and fixing the three-layer fabric, the supporting strip is also fused and fixed between the three layers. As mentioned above, the  supporting strip is fused and fixed between the three layers, which is a serious defect.
Due to welding by the ultrasonic welding wheel, an obvious row of pressure marks is formed due to adhesion of said fabric by high temperature melting. The pressure mark is a relatively weaker portion in structure and may be broken by melting or tearing. The wearer cannot make sure whether the mask body has holes and doubts safety of wearing the face mask. A manufacturer also cannot make sure that the mask body is absolutely free from holes. Therefore, the risk is transferred to the wearer. Especially in rapid production, it is not easy to find breaks and holes. When the pressure marks are disposed at the margins of the three-layer fabric, even if the margins are partially damaged, since the damage is not at a main ventilation surface, the protection and filtering effect will not be affected. However, the support strip 91 is disposed at a central portion of the mask body, such that two rows of pressure marks 92 respectively disposed at the upper and lower sides of the support strip 91 will extend across the central portion of the mask body, which is the main region of the mask body for filtering bacteria and viruses. Therefore, once the two rows of pressure marks have a broken portion, the broken portion will result in a hole in the central portion of the mask body, which will directly endanger the protecting effect of the face mask.
In addition, in the process of wearing the face mask, the ear loops disposed at both sides will inevitably be pulled, which will cause a certain pulling force on the mask body. Therefore, it will lead to a certain risk of tearing at the pressure mark 92 next to the supporting strip of the mask body.
In addition, with the continuous welding time, the temperature of the rolling ultrasonic welding wheel will become higher and higher. Therefore, the face mask made by a rolling ultrasonic welding wheel, which has continuously welded so many face masks for a long time, will be weaker in structure and is easier to be torn and broken in the pressure marks 92 due to the high  temperature. Therefore, the risk of breaking due to melting and tearing of the pressure mark 92 disposed at a central portion of the mask body cannot be ignored.
Therefore, in order to be equipped with the supporting strip, the conventional face mask and the method for making the conventional face mask having high risk of damage an inherent protecting effect of the face masks have to be improved indeed.
Summary of the invention:
The main objective of the present invention is to provide a method to eliminate that the supporting strips of the conventional face mask damage protecting effect of the face masks and to create a method for a making mask body and the mask body that is free from jeopardizing the protecting effect.
A method for making a mask body of a face mask with supporting strips has the following steps: connecting at least one supporting strip to an interior layer to jointly form a pre-connection portion, and then connecting an exterior layer and a middle layer to the pre-connection portion to make a margin of the exterior layer, a margin of the middle layer, and a margin of the interior layer connected mutually.
The advantage of the present invention is that the one-time manufacturing process of the method for making the conventional face mask is divided into the two steps. In the first step, the at least one supporting strip and two of the three layers are connected together (ex. via ultrasonic welding) or the at least one supporting strip is merely connected to the interior layer. Therefore, the middle layer and the exterior layer are free from being damaged during the manufacturing process of the present invention. In the second step, the structure produced in the first step is jointly connected to the other layers. In the second step, the connection is applied only at margins of the mask body. Therefore, the connection in the second step is free from damaging the central portions of each layer (the main ventilation surface) and from diminishing filtering and protection effect of  the mask body.
The mask body of the conventional face mask manufactured by the conventional method for making the conventional face mask has the pressure marks, is easy to be torn and damaged, and has high risk of breaking. Compared to the conventional method for making the conventional face mask, the exterior layer or even the exterior layer and the middle layer of the mask body of the present invention do not have marks of connection such as pressure marks and are free from being affected by the pressure marks. Compared to the conventional method for making the conventional face mask, the present invention significantly promotes protection effect of the mask body and sustains inherent effect of the face masks.
A method for making a mask body of a face mask with supporting strips has the following steps: connecting at least one supporting strip between a middle layer and an interior layer to jointly form a pre-connection portion, and then connecting an exterior layer to the pre-connection portion to make a margin of the exterior layer, a margin of the middle layer, and a margin of the interior layer connected mutually.
A mask body of a face mask with supporting strips has a pre-connection portion, an exterior layer, and a middle layer. The pre-connection portion has an interior layer and at least one supporting strip. The interior layer has a top edge, a bottom edge, and a central portion disposed between the top edge and the bottom edge. The at least one supporting strip is fixed on the interior layer and corresponds to the central portion of the interior layer in position. After the at least one supporting strip is connected to the interior layer, the exterior layer and the middle layer are connected to the pre-connection portion. And a margin of the exterior layer, a margin of the middle layer, and a margin of the interior layer are connected mutually. The middle layer is disposed between the exterior layer and the pre-connection portion.
A mask body of a face mask with supporting strips has a pre-connection portion and an  exterior layer. The pre-connection portion has an interior layer, a middle layer, and at least one supporting strip. The interior layer has a top edge, a bottom edge, and a central portion disposed between the top edge and the bottom edge. The at least one supporting strip is fixed between the middle layer and the interior layer and corresponds to the central portion of the interior layer in position. After the at least one supporting strip is fixed between the interior layer and the middle layer, the exterior layer is connected to the pre-connection portion. And a margin of the exterior layer, a margin of the middle layer, and a margin of the interior layer are connected mutually. The middle layer is disposed between the exterior layer and the pre-connection portion.

Detailed description
The method for making a mask body of a face mask with supporting strips and the mask body has eight embodiments but are not restricted by the eight embodiments. The first to the third embodiments, and the fifth to the seventh embodiments include the following two steps.
Step 1: with reference to Fig. 5, deploy at least one supporting strip 50 between a fixation layer 40 and an interior layer 10. The interior layer 10 has a top edge 11, a bottom edge 12, and a  central portion 13 disposed between the top edge 11 and the bottom edge 12. The at least one supporting strip 50 is disposed at the central portion of the interior layer 10 corresponding in position. Preferably, with reference to Fig. 6, said supporting strip 50 corresponds to a nose, a mouth, or a nose bridge of a wearer in position.
A height of the fixation layer 40 is preferably smaller than a height of the interior layer 10. In the first embodiment (Fig. 4) and in the fifth embodiment (Fig. 11) , a width of the fixation layer 40 is preferably larger than a width of the supporting strip 50 to make sure that the fixation layer 40 can cover the said supporting strip 50. The fixation layer 40 is not restricted to entirely cover the said supporting strip 50. Two ends of the said supporting strip 50 can extend to two lateral sides of the fixation layer 40. Moreover, the width of the fixation layer 40 is preferably equal to a width of the interior layer 10 so that the two lateral sides of the fixation layer 40 can be fixed to the other layers at least. However, the width of the fixation layer 40 is not restricted to be equal to the width of the interior layer 10. In addition, an area of the fixation layer 40 may be equal to an area of the interior layer 10 as illustrated in the third embodiment (Fig. 8) and the seventh embodiment (Fig. 13) . The mask body can be considered as a structure with four layers accordingly.
Then, fix the said supporting strip 50 between the fixation layer 40 and the interior layer 10, and a pre-connection portion is jointly formed by the said supporting strip 50, the fixation layer 40 and the interior layer 10. Preferably, with reference to Fig. 17, the said supporting strip 50, the fixation layer 40, and the interior layer 10 can be fused by an ultrasonic welding wheel 80 for connection. Nevertheless, the said supporting strip 50, the fixation layer 40, and the interior layer 10 are not restricted to be connected by the ultrasonic welding wheel 80 and can also be connected via glue or other connection means.
Step 2: with reference to Figs. 3 to 5, connect an exterior layer 30 and a middle layer 20 to the pre-connection portion, and make a margin of the exterior layer 30, a margin of the middle  edge layer 20, and a margin of the interior layer 10 connected mutually (as shown in Figs. 1 and 2) to form the mask body of the face mask. Preferably, the exterior layer 30, the middle layer 20, and the pre-connection portion are fused together by ultrasonic welding. However, the exterior layer 30, the middle layer 20, and the pre-connection portion are not restricted to be connected by ultrasonic welding and may be connected via other connection means.
Meanwhile, when the area of the fixation layer 40 and the area of the interior layer 10 are equal as illustrated in the third embodiment (Fig. 8) and in the seventh embodiment (Fig. 13) , a margin of the fixation layer 40 is also connected to the margins of the exterior layer 30, the middle layer 20, and the interior layer 10 together.
Besides, said margins connected together are not restricted to entirely encircle the mask body. For example, the said margins connected together can be merely two opposite edges fixed together (such as top edge 11 and bottom edge 12) .
In addition, when the exterior layer 30 and the middle layer 20 are connected to the pre-connection portion, the exterior layer 30 and the middle layer 20 are connected in a direction that the middle layer 20 is disposed between the exterior layer 30 and the pre-connection portion. Moreover, the fixation layer 40 may be disposed between the middle layer 20 and the interior layer 10 like the first embodiment (Fig. 4) and the fifth embodiment (Fig. 11) . The interior layer 10 can be disposed between the middle layer 20 and the fixation layer 40 like the second embodiment (Fig. 7) and the sixth embodiment (Fig. 12) .
Furthermore, when the area of the fixation layer 40 and the area of the interior layer 10 are equal, the mask body may be considered as a structure with four layers. A layer disposed at an innermost side can be the fixation layer 40 like the third embodiment (Fig. 8) . The layer disposed at the innermost side may be the interior layer 10 alternatively like the seventh embodiment (Fig. 13) .
In a preferred embodiment, the exterior layer 30 is an impermeable layer, the middle layer 20 is a filter layer, and the interior layer 10 may be an absorbent layer or a skin layer. Materials of the fixation layer 40 and the exterior layer 30 may be the same. However, the material of the fixation layer 40 is not restricted to be same as the material of the exterior layer 30, and the material of the fixation layer 40 may be same as the material of the interior layer 10 or be adjusted depending on demand.
With reference to Figs. 9 and 14, the fourth embodiment and the eighth embodiment of the method for making the mask body also include two steps. The fourth embodiment and the eighth embodiment differ from aforementioned six embodiments in that the fixation layer is omitted in the fourth and the eighth embodiments and replaced by the middle layer 20. And the mask body is still a structure with three layers. Therefore, in the step 1, the said supporting strip 50 is fixed between the middle layer 20 and the interior layer 10 alternatively. And the said supporting strip 50, the middle layer 20, and the interior layer 10 are formed to be the pre-connection portion jointly. In step 2, the exterior layer 30 is connected to the pre-connection portion to also make the margins of the exterior layer 30, the middle layer 20, and the interior layer 10 fixed together.
In addition to the abovementioned, details of the fourth embodiment and the eighth embodiment are substantially same as the aforementioned six embodiments and are not repeated here.
In addition, the mask bodies of the aforementioned eight embodiments can be configurations without pleats (such as three-dimensional face masks) or with pleats (such as surgical masks) . The configurations with pleats may at least include lightning type (such as the first embodiment to the fourth embodiment) and omega type (such as the fifth embodiment and the eighth embodiment) .
When the height of the fixation layer 40 is smaller than the height of the interior layer 10  and the mask body (the interior layer 10) is a configuration with pleats, the height of the fixation layer 40 preferably corresponds to one of the pleats of the interior layer 10 specifically illustrated as follows. Besides, when the mask body is a configuration with pleats, the exterior layer 30, the middle layer 20, and the interior layer 10 all have pleats. The following description only takes the interior layer 10 as an example.
The lightning type: with reference to Figs. 3 to 5, the interior layer 10 has a first pleat 13, a second pleat 14, and a third pleat 15 disposed parallel to one another and arranged at intervals. The first pleat 13 is disposed adjacent to the top edge 11 of the interior layer 10, the second pleat 14 is disposed below the first pleat 13, and the third pleat 15 is disposed below the second pleat 14. The third pleat 15 may be disposed adjacent to the bottom edge 12 of the interior layer 10, or there may be more pleats disposed between the third pleat 15 and the bottom edge 12 of the interior layer 10.
The first pleat 13 includes a first exterior sheet 131 and a first interior sheet 132. A bottom side of the first exterior sheet 131 and a bottom side of the first interior sheet 132 are connected in a bending manner.
The second pleat 14 includes a second exterior sheet 141 and a second interior sheet 142. A bottom side of the second exterior sheet 141 and a bottom side of the second interior sheet 142 are connected in a bending manner. A top edge of the second exterior sheet 141 and a top edge of the first interior sheet 132 are connected in a bending manner.
The third pleat 15 includes a third exterior sheet 151 and a third interior sheet 152. A bottom side of the third exterior sheet 151 and a third interior sheet 152 are connected in a bending manner. A top edge of the third exterior sheet 151 and a top edge of the second interior sheet 142 are connected in a bending manner.
The fixation layer 40 and the said supporting strip 50 are connected to the second exterior  sheet 141. And the height of the fixation later 40 corresponds to the height of the second exterior sheet 141 but is not restricted thereto. That is, the fixation layer 40 extends upward to a bending connection between the top edge of the second exterior sheet 141 and the top edge of the first interior sheet 132, and the fixation layer 40 extends downward to a bending connection between the bottom side of the second exterior sheet 141 and the bottom side of the second interior sheet 142.

As stated above, we know that in the first to the third embodiments and in the fifth to the seventh embodiments, the at least one supporting strip 50 is connected between the fixation layer 40 and the interior layer 10. And in the fourth and the eighth embodiments, the at least one supporting strip 50 is connected between the middle layer 20 and the interior layer 10 but not restricted to that. With reference to Fig. 16, the supporting strips 50 can be merely connected to the interior layer 10. In other words, the pre-connection portion does not include the fixation layer 40 and the middle layer 20, the pre-connection portion just includes the at least one supporting strip 50 and the interior layer 10. And in the step 1, only the at least one supporting strip 50 is connected to the interior layer 10 such as welding the at least one supporting strip 50 to the interior layer 10 by ultrasonic welding or adhering the at least one supporting strip 50 to the interior layer 10 by glue, etc., to avoid damage to the middle layer 20 and the exterior layer 30 as well. Such manner can also be suitable for variations mentioned above, such as the lightning type, omega type, or various positions of the at least one supporting strip 50, and so on.
To sum up, the abovementioned content is explaining the manufacturing process of the mask body. In the aforementioned process, the ear loops 60 and the nose clip 70 may be connected to the mask body at the same time. The ear loops 60 and the nose clip 70 can be connected to the mask body after said mask body is manufactured.
An advantage of the present invention is that via two steps, the at least one supporting strip 50 and two of the three layers (the fixation layer 40 and the interior layer 10, the middle layer 20 and the interior layer 10) are connected together firstly, the connection process at this stage is free from damaging the middle layer 20 and the exterior layer 30. Eventually, the structure manufactured in step 1 is connected to the other layer. In step 2, margins of the three layers are connected without damaging the central portion of the main ventilation surface and are free from diminishing the filtering and protecting effect. The present invention makes sure that the exterior layer 30 (the fourth embodiment and the eighth embodiment) or even the exterior layer 30 and the middle layer 20 (the rest six embodiments) is free from being affected and can maintain original structural rigidity.
Inside the mask body, with reference to Fig. 2, the pressure marks 51 are still formed at the at least one supporting strip 50 and the interior layer 10. However, outside the mask body, with reference to Fig. 1, there are no the pressure marks generated in the connection process disposed at the exterior layer 30 and the at least one supporting strip 50.
The present invention can effectively decrease impact on rigidity of the overall structure as the at least one supporting strip 50 is connected to the three layers and sustains a certain protecting effect, and there is no pressure mark disposed outside. The present invention can prevent the wearer from doubting protecting effect of the present invention and let the wearer feel relieved psychologically.
In addition, the other advantage of the present invention is that the manufacturer can directly use the present face mask manufacturing apparatus (ultrasonic welding wheel) to process the two connections by ultrasonic welding with slight adjustment and without purchasing other equipment. Thereby, the mask body with aforementioned functions can be manufactured without costing a lot.
