Description

Three-dimensional mask and its manufacturing method

The present invention relates to a mask, in particular to a three-dimensional mask that is soft, can be worn on the face and can block droplets, bacteria or viruses, and a manufacturing method thereof.

Masks have been widely used in various occasions for the purpose of isolating polluted air or dust and ensuring that the human body or products are not contaminated. In addition to the expansion of severe and special infectious pneumonia, the demand and consumption of masks are increasing. How to provide a mask with proper function, low cost and comfortable to wear is a major issue for the current industry. Generally, traditional masks have no more than flat gauze (or cotton) with a single layer or multiple layers on the outer layer, or Single-layer, multi-layer flat paper products (or non-woven products), and with elastic bands that can be hung on the user’s ears.

The flat structure will press on the human face and directly touch and rub with the human mouth, which will easily wet the mask with saliva and produce peculiar smell; there are obvious gaps around, and the adhesion effect is not good, causing air pollutants or germs to remain. It will pass through the edge of the mask and be inhaled by the user; the ears will feel uncomfortable under the force of the string-like elastic band for a long time. Due to the above-mentioned problems, the practicability of conventional flat masks is not good, and there should be a need for improvement.

The main purpose of the present invention is to provide a three-dimensional mask and its manufacturing method. The mask can be worn on the face, and its elastic ears increase the comfort of wearing for a long time, and can isolate and filter harmful substances.

In order to achieve the above-mentioned object, the present invention provides a three-dimensional mask, which includes: an outer layer, made of elastic cloth, with a mask part; two hanging ears, respectively arranged on two sides of the mask part; at least one middle layer, A filter layer; an inner layer; the middle layer is located between the outer layer and the inner layer; wherein: the periphery of the mask portion of the outer layer, the periphery of the middle layer and the periphery of the inner layer are bonded to each other; the outer layer, The middle layer and the center of the inner layer are adhered from the top edge to the bottom edge to form an arc-shaped adhesive line, which protrudes from the outer surface of the outer layer.

Wherein, the top edge of the middle layer and the inner layer is bonded to the outer layer by a top bonding line; the bottom edge of the middle layer and the inner layer is bonded to the outer layer by a bottom bonding line; the middle layer is bonded to the outer layer The two sides of the inner layer are each bonded to the outer layer by a bonding wire on one side.

Wherein, the top bonding line, the bottom bonding line and the two-side bonding line are symmetrically located on both sides of the arc-shaped bonding line.

Wherein: the top adhesive line is inclined outwards and downwards on both sides of the arc-shaped adhesive line; the bottom adhesive line is inclined outwards and upwards on both sides of the arc-shaped adhesive line.

Wherein, the mask part of the outer layer and the ear hangers are integrally formed.

Wherein, the middle layer is a melt-blown non-woven fabric, which is an electrostatic filter layer, which can filter bacteria or viruses.

Among them, the inner layer is made of skin-friendly material, made of woven or non-woven fabric, which can absorb sweat and grease.

Preferably, in the three-dimensional mask provided by the present invention and its manufacturing method, after the outer layer, the middle layer and the inner layer are folded in half, the middle bonding line is welded/bonded into an arc with high frequency, and the arc is not cut when cutting The shape of the adhesive knot makes the mask a three-dimensional shape after opening, which can be comfortably attached to the user's face.

Preferably, the three-dimensional mask provided by the present invention has a better adhesion effect because it fits on the face of the user, and it is not easy to cause air pollutants or germs to pass through the edge of the mask and be inhaled by the user. When exhaling, the hot air rushes upwards, causing the glasses to fog.

Preferably, the three-dimensional mask provided by the present invention has soft elasticity and recovery characteristics in the outer layer, so the tension and contraction recovery force are moderate, and the ear hook and the mask part are integrally formed. Compared with the traditional elastic band ear hook mask, The ears are less stressed, thus providing better comfort.
