Elastic band for mask and production method of elastic band

Abstract

The invention relates to an elastic band for a mask and a production method of the elastic band. The elastic band comprises a flat and tubular elastic band body, strip-shaped gaskets used for being arranged around ears of a human body during wearing are uniformly arranged in an inner cavity of the elastic band body in the length direction, and the distance between the middle points of every two adjacent gaskets is 16-22 cm; and the average width of the gaskets is not less than 0.4 cm. According to the elastic band for the mask, production equipment does not need to be additionally arranged, the elastic band can directly replace a common elastic band to be produced on a high-speed mask machine, and compatibility is good; according to the mask using the elastic band, the gaskets increase the contact area of the elastic band and the ear roots of the human body, the width of the tail end of the gasket is increased, the gasket makes contact with the soft ear lobes, more pressure can be borne, and the comfort level is increased; and moreover, due to the fact that the arrangement cost of the gaskets is low, the gaskets are suitable for being applied to the disposable mask, and the good application prospect is achieved.

Description

technical field [0001] The invention belongs to the technical field of elastic bands, and in particular relates to an elastic band for masks and a production method thereof. Background technique [0002] Disposable masks made of melt-blown cloth and elastic belts have become a must-have item for people to travel at present. The low cost of disposable masks and the characteristics of throwing away after use enable people to use them at a relatively low cost, providing people with Great convenience and enough protection. The elastic belt of the mask is mostly fixed with elastic string and the main body of the mask by ultrasonic welding. When the mask is worn, the elastic string hangs on the ear. The elastic string is easy to be strangled or even strangled during wearing, especially when wearing a disposable mask with high protection level (such as N95, etc.), a more elastic elastic string is required, and it is easy to produce strangle marks after long-term use , Redness, sw...

Problems solved by technology

The elastic belt of the mask is mostly fixed with elastic string and the main body of the mask by ultrasonic welding. When the mask is worn, the elastic string hangs on the ear. The elastic string is easy to be strangled or even strangled during wearing, especially when wearing a disposable mask with high protection level (such as N95, etc.), a more elastic elastic string is required, and it is easy to produce strangle marks after long-term use , it is common to have redness, swelling and tingling at the strangle mark

[0003] The application number is CN201520519389.0, and the utility model patent named "A Medical Surgical Mask" discloses a medical surgical mask with a silicone pad in the middle of the elastic band, which has good comfort and will not wear for a long time. There is a feeling of discomfort, but medical surgical masks are usually disposable, and this medical surgical mask with a silicone pad will undoubtedly greatly increase the cost of the mask, causing waste and pollution; and, if the silicone pad is fixed on the On the elastic belt, this will undoubtedly increase the difficulty of production. Even if additional silicone pads are added to fix professional equipment, the production efficiency and yield rate will be greatly reduced.

[0004] The application number is CN202020925809.6, and the utility model patent titled "A Mask Easy for Children to Wear" discloses a mask with a protective cover on the surface of the elastic band. The setting of the protective cover is more flexible, but Also due to higher production and material costs, it is still not suitable for the production of disposable masks
