Abstract

This creation is a mask body with support strips. When manufacturing, the support strips are first combined and fixed between the fixed layer and the inner layer to form a pre-joining part, and then the outer layer and the middle layer are joined to the pre-joining part. Fix the edges of the outer layer, middle layer, and inner layer to each other. In this creation, through two processes, firstly, only the support bar and the fixed layer are combined with the inner layer, so the middle layer and outer layer will not be damaged during the combination process. The second processing is combined with the outer layer and the middle layer only at the edges, without affecting the overall filtering and protection. In this way, the outer layer and the middle layer of this creation will not have any combination marks such as indentations, and thus can avoid the wearer's doubts about the protective effect. This creation can improve the defect that the protective effect of the mask will be damaged when the support strip is installed on the existing cover.

Description

Cover body of mask with supporting strip

This creative department relates to a mask with supporting strips.

Please refer to FIG. 18, in order to improve the comfort of wearing a mask in the prior art, a support bar 91 is provided on the mask body, so that the mask body can maintain a forward curved shape, so that the mask body can be worn with A certain space is supported between the mouth and nose of the wearer, so as to prevent the cover from repeatedly touching and leaving the wearer’s facial skin during exhalation and inhalation, which will cause discomfort to the wearer.

However, the manufacturing method of masks with supporting strips in the prior art will result in serious shortcomings. Specifically, the masks of the masks in the prior art usually include three layers, which are an absorbent layer, a filter layer, and Waterproof layer, the water-absorbing layer is used to absorb the wearer's mouth foam, sweat or exhaled moisture, and the waterproof layer is used to prevent the penetration of droplets from the outside.

Generally, for masks without supporting strips, the aforementioned three layers of fabrics are directly superimposed on each other, and the ultrasonic welding wheel is pressed and rolled down to weld the edges of the three layers of fabrics together to form a cover.

However, when manufacturing masks with support strips in the prior art, before welding, the support strips are directly placed between the two layers of fabric, and then the ultrasonic welding wheel is pressed and rolled down, and the fabrics of each layer follow the upper and lower sides of the support strip. The two sides are welded and fixed to fix the position of the support bar. However, in addition to the edge welding and fixing of the three-layer fabric, as mentioned above, the support strip will also be welded and fixed between the three-layer fabric at the same time, and this will cause a serious disadvantage.

When welding through the ultrasonic welding wheel, a whole row of obvious indentations will be formed due to the high heat melting of the fabrics. The indentations are relatively weak in the structure, and they are easy to melt and cause damage or tear from there. However, users cannot confirm whether there is a hole or not, and they will have safety concerns about wearing, and the manufacturer cannot guarantee that there will never be a hole. Therefore, the risk is passed on to the user, especially in rapid production, if there is damage, Holes are not easy to find. When the indentation is located on the edge of the three-layer fabric, even if the edge of the indentation is partially damaged, since the damage is not on the main air circulation surface, the protection and filtering effect will not be affected. However, the support bar 91 is located in the center of the cover, so the two rows of indentations 92 on the upper and lower sides of the support bar 91 will span the center of the cover, that is, the mask mainly filters bacteria and viruses. Therefore, once the two rows of pressure Any damage to the mark 92 will result in a hole in the center of the mask, which will directly destroy the protective effect of the mask.

In addition, during the process of wearing the mask, the ears on both sides will inevitably be pulled, which will cause a certain pulling force on the mask body, which will lead to the indentation 92 at the support bar of the mask body. There is indeed a certain degree of tearing. risk.

In addition, when the ultrasonic welding wheel is welded, the temperature will become higher and higher with the continuous welding time. Therefore, the indentation 92 of the mask welded after long-term continuous use will cause the structure to be weaker and easier due to the high temperature. Tearing, breakage. Therefore, the risk of melting, tearing, and breakage of the indentation 92 located in the center of the cover cannot be ignored.

Therefore, the prior art masks with supporting strips and the manufacturing method thereof, in order to provide the supporting strips, have a very high risk of damaging the protective effect of the masks, and need to be improved.

In view of the aforementioned shortcomings and shortcomings of the prior art, this creation provides a method that can eliminate the damage of the protective effect of the prior art mask, and then creates a cover that does not affect the protective effect.

In order to achieve the above-mentioned creative purpose, the technical means used in this creation is to design a mask body with supporting strips, which contains A pre-bonding portion, which includes an inner layer and at least one support bar, the inner layer has a top side, a bottom side, and an intermediate part between the top side and the bottom side, and the at least one support bar is fixed to On the inner layer, and the position of the at least one support bar corresponds to the middle part of the inner layer; An outer layer and a middle layer. After the at least one support bar is fixed on the inner layer, the outer layer and the middle layer are bonded to the pre-bonding portion, and the edges of the outer layer, the middle layer and the inner layer are fixed to each other , The middle layer is located between the outer layer and the pre-bonding part.

In order to achieve the above creative purpose, this creation further provides a mask body with a support strip, which contains A pre-bonding portion, which includes an inner layer, a middle layer, and at least one support bar.

The advantage of this creation is that the prior art manufacturing process of one-time processing is divided into two processings. Firstly, only the support bar and its two layers are combined (for example, through ultrasonic welding) or only the support bar is combined to the inner layer. This can prevent damage to the middle and outer layers during the bonding process. Finally, they are combined together (for example, through ultrasonic welding) to other layers, and the second combination is only combined at the edge, so that this combination will not damage the center of each layer (the main air circulation surface). Will affect the effect of filtering and protection.

Compared with the prior art, the three-layer fabric will have indentations and is easy to tear, break and have a huge risk of holes. The outer layer or even the outer layer and the middle layer of this creation will not have indentations and other combined marks. It will be affected, so it can not only avoid the wearer's doubts about the protective effect, compared with the existing technology, this creation can greatly improve the protective effect, and can maintain the protective ability of the mask.
