Description

A mask with a crease structure that makes the mask fold flat and three-dimensionally supported

technical field

The invention relates to a foldable mask, in particular to a mask with a crease structure which enables the mask to be folded flat and three-dimensionally supported.

Background technique

Generally, the existing folding mask structure only has folded creases repeatedly, and the folding methods and directions of each crease are single and parallel, without different changes. There are elastic bands for hanging ears at both ends of the body, so the following three defects are prone to occur;

First, because the folding method and direction of the folds of the existing folded masks are single and parallel, the three-dimensional structure in the stretched state will be limited by the creases of each level, so that the mask can be supported when unfolded. Insufficient strength;

Second, because the folding method and direction of the creases of the existing folded masks are single and parallel, when the masks are stretched, the supporting parts protruding from each crease will be misaligned, so that the supporting force is not concentrated, and the folding There will be unevenness when folding;

Third, because the existing folding masks are all ear-hanging type, the two ends of the mask do not have a constricting structure, so when the user unfolds the mask for use, the two ends of the mask form a semi-arc shape due to the pulling of the ear-hanging elastic belt The opening of the mask greatly affects the sealing and insulation of the mask;

To sum up, in order to overcome the aforementioned problems, a mask with a crease structure that enables the mask to be folded flat and three-dimensionally supported is needed.

Contents of the invention

The invention provides a mask with a crease structure that makes the mask fold flat and three-dimensionally supported. The main purpose of the mask is to make the mask have stronger support and three-dimensional effect when unfolded.

Another object of the present invention is to enable the mask to be quickly and flatly folded when being folded, so as to facilitate storage by the user.

Another object of the present invention is to improve the sealing degree of the mask during use, thereby improving the ability to filter dirty air and dust.

In order to achieve the aforementioned purpose, the present invention has a mask with a crease structure that makes the mask fold flat and three-dimensionally supported, and is used to cover the user's face, and the mask with a fold structure that makes the mask fold flat and three-dimensionally supported, include:

Two main body sheets, two folded parts and a main cover sheet are connected, the main body sheet, the folded part and the main cover sheet all extend along a transverse direction, and the main body sheet, the folded part and the main cover sheet are arranged in the horizontal direction The two ends respectively have a first end and a second end, the first ends of the main cover sheet, the main sheet, and the folded portion are superimposed on each other, and the main cover sheet, the main sheet, and the second end of the folded portion The ends are overlapped with each other, and the main mask sheet, the main body sheet, and the folded portion respectively form a crimping portion at the overlapped position of the first end and the second end;

2. the main body sheet is arranged along a stretching direction, and the stretching direction is perpendicular to the transverse direction; 2. the main body sheet is attached to the user's face;

2. The folded portion is connected between the two main body sheets and the main cover sheet, and the folded portion has at least three folded sheets connected in sequence;

Two ends of the main mask along the stretching direction are respectively connected to the two folded parts; and

an adhesive layer, located on the two main body sheets, the adhesive layer is used to adhere the two main body sheets to the user's face;

In the folded state, the two main body pieces are adjacent to each other, and the folded pieces are superimposed on each other; in the stretched state, the two main body pieces are away from each other along the center of the transverse direction, and the two main body pieces The first end and the second end are still superimposed on each other, and each of the folded pieces is stretched and not superimposed to form a three-dimensional structure.

Preferably, the main cover sheet, the main body sheet and the folded portion have a continuous three-dimensional fold extending along the stretching direction.

Preferably, the first end and the second end are respectively provided with an escape hole, and when the mask is unfolded, the mask with a crease structure that enables the mask to be folded flat and three-dimensionally supported is placed on both sides of the escape hole. The part of the side that will enter the escape hole overlaps.

As can be seen from the foregoing, the mask provided by the present invention has a crease structure that makes the mask fold flat and three-dimensionally supported mainly by making the two folded parts respectively connect the main cover sheet and the two main body sheets, because the two folded parts have at least three Therefore, in the state of stretching, each of the folded sheets will unfold and pull each other, and form a natural three-dimensional structure through the force of each of the folded sheets in the opposite direction, so as to achieve better support and strength of the mask. Three-dimensional purpose.

The present invention also forms the continuous three-dimensional crease extending along the stretching direction on the main cover sheet, the main body sheet, and the folded portion, so that the mask has better support in the stretched state, and can be folded in a folded state. It can be folded quickly and flatly.

In the present invention, the escape holes are respectively provided at the first end and the second end to avoid wrinkles and gaps at the connection between the main body sheet and the folded part at the first end and the second end when the mask is unfolded, Thereby, the purpose of improving the sealing degree of the mask is achieved.
