Description

Hygroscopic gasket and mask with hygroscopic gasket

The present invention relates to an absorbent pad, in particular to an absorbent pad containing an adhesive layer and a mask with the absorbent pad.

In recent years, due to the increasing pollution of airborne particulates and the spread of diseases through droplets, masks that can block germs or particles have gradually received attention.

Since the mask usually needs to be worn for a long time, the mask is easily exposed to a large amount of moisture exhaled from the wearer's mouth and nose, and is dampened, thereby reducing the barrier effect of the mask itself. The existing solution is to put a moisture absorption pad that can absorb moisture inside the mask and then put it on to absorb the moisture exhaled from the wearer's mouth and nose, so that the barrier effect of the mask can be continued.

However, the above-mentioned absorbent pads tend to shift with the action of the wearer or fall off when the wearer removes the mask, which may easily lead to that the absorbent pad cannot effectively prevent the moisture from directly contacting the mask, or the absorbent pad needs to be replaced. Wet gasket.

Therefore, the purpose of the present invention is to provide an absorbent pad which can overcome the above-mentioned shortcomings of the prior art.

Therefore, the novel absorbent pad includes a breathable hydrophilic layer, a breathable water-repellent layer, and an adhesive layer. The breathable water repellent layer is attached to one side of the breathable hydrophilic layer. The adhesive layer is adhered to a side of the breathable water repellent layer opposite to the breathable hydrophilic layer.

Therefore, another object of the present invention is to provide a mask with an absorbent pad, which can overcome the above-mentioned shortcomings of the prior art.

Thus, the mask of the present invention having an absorbent pad includes an inner layer, a filter layer laid on the inner layer, an outer layer laid on the filter layer, and an absorbent pad as described above. This inner layer is suitable for contact with the wearer's skin. The filter layer is suitable for blocking germs or particles. The outer layer is suitable for blocking droplets or liquids, and forms a three-layer structure together with the inner layer and the filter layer. The absorbent pad is adhered to the inner layer by the adhesive layer.

The effect of the present invention is that the hygroscopic pad can be fixedly adhered to the inner layer of the mask, and will not shift with the action of the wearer or fall off when the wearer removes the mask.

The following will explain the new content in detail:

Preferably, the breathable hydrophilic layer and the breathable water-repellent layer have substantially the same shape and size.

Preferably, the shapes of the breathable hydrophilic layer and the breathable water-repellent layer are in the shape of dumbbells whose middle part is slightly narrower than both ends. More preferably, the adhesive layer is adjacent to both ends of the breathable water repellent layer.

Optionally, the breathable hydrophilic layer is selected from hydrophilic nonwoven fabric, hydrophilic modified polyethylene breathable film, hydrophilic modified polypropylene breathable film or hydrophilic foam.

Optionally, the breathable water-repellent layer is selected from water-repellent nonwoven fabric, polyethylene breathable membrane, polypropylene breathable membrane or polytetrafluoroethylene (PTFE) breathable membrane.

Optionally, the adhesive layer is selected from hot melt adhesive or double-sided adhesive.

Preferably, the novel absorbent pad further includes a release paper covering the adhesive layer.

Preferably, the mask of the present invention with an absorbent pad further includes two ear hooks, which are respectively installed on two opposite short sides of the three-layer structure.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same number.

The present invention will further explain the following embodiments, but it should be understood that this embodiment is for illustrative purposes only, and should not be construed as a limitation of the implementation of the new model.

Referring to FIG. 1, an embodiment of the novel absorbent pad 1 includes a breathable hydrophilic layer 11, a breathable water repellent layer 12, an adhesive layer 13 and a release paper 14.

In this embodiment, the breathable hydrophilic layer 11 is a hydrophilic non-woven fabric.

The breathable water-repellent layer 12 is attached to one side of the breathable hydrophilic layer 11. In this embodiment, the breathable water-repellent layer 12 is a water-repellent non-woven fabric.

The adhesive layer 13 is adhered to a side of the breathable water repellent layer 12 opposite to the breathable hydrophilic layer 11. In this embodiment, the adhesive layer 13 is double-sided adhesive.

The air-permeable hydrophilic layer 11 and the air-permeable water-repellent layer 12 have the same shape, size and thickness. The shapes of the breathable hydrophilic layer 11 and the breathable water-repellent layer 12 are in the shape of dumbbells whose middle part is slightly narrower than both ends. The adhesive layer 13 is adjacent to both ends of the breathable water repellent layer 12.

The release paper 14 covers the adhesive layer 13 removably.

Referring to FIG. 2, the mask 2 of the present invention having an absorbent pad 1 includes an inner layer 21, a filter layer 22 laid on the inner layer 21, an outer layer 23 laid on the filter layer 22, and an absorbent pad Piece 1 and two ear hooks 24.

The inner layer 21 is suitable for contact with the skin of the wearer.

The filter layer 22 is suitable for blocking germs or particles.

The outer layer 23 is suitable for blocking droplets or liquids, and forms a three-layer structure together with the inner layer 21 and the filter layer 22.

After the release paper 14 of the absorbent pad 1 described above is torn off, the adhesive layer 13 is fixedly adhered to the inner layer 21.

The ear hooks 24 are respectively installed on two opposite short sides of the three-layer structure.

In summary, the new absorbent pad can be fixedly adhered to the inner layer of the mask by the adhesive layer to absorb the moisture exhaled from the wearer's mouth and nose, and will not follow the wearer's action Displacement or falling off because the wearer removes the mask can keep the mask dry, so it can really achieve the purpose of new cost.

However, the above are only examples of the new model. When the scope of the new model cannot be limited by this, any simple equivalent changes and modifications made according to the patent application scope and patent specification content of the new model are still regarded as Within the scope of this new patent.
