Description

Fully-pasted or partially-pasted fixed mask

Technical Field

The utility model belongs to the technical field of the personal protection gauze mask technique and specifically relates to a paste fixed gauze mask entirely or partly.

Background

The mask is a sanitary product, is generally worn at the mouth and nose part for filtering air entering the lung so as to achieve the effect of blocking harmful gas, smell, spray, virus and other substances, and has a very good protection effect when the mask is worn in respiratory infectious diseases and works in the environment polluted by dust and the like.

The gauze mask that uses at present requires with the fine laminating of face, but because everybody facial characteristics is different, the gauze mask of industrialization batch production can not be fine hugs closely with face, and harmful gas leaks the entry nose side from the space of never hugging closely with face easily, reduces the protective effect of gauze mask. In addition, since the existing mask is fixed on the face by straps, the fixing mode usually causes users to feel a binding feeling, when the straps are too tight, the users feel uncomfortable on the face or ears, and when the straps are not tight, the users are exposed to harmful air because the mask is often dropped off during movement. The defects of the masks affect the health and wearing comfort of users.

Chinese patent documents: CN201320653195.0, application date 2013.10.22, patent names: a gauze mask without laces. The strapless mask comprises a mask main body for covering the mouth and the nose, wherein a pressure-sensitive adhesive tape layer is arranged on the outer edge of the inner side of the mask main body and used for keeping the mask main body on the face and closing a gap between the skin of the face and the mask main body; the mask main body is flat after being unfolded, and two ends of a long shaft of the mask main body are mutually bonded by pressure sensitive adhesive attaching layers, so that the mask main body forms a three-dimensional convex structure, and fin-shaped convex structures are formed at two ends of the long shaft of the mask main body; the pressure-sensitive adhesive sticking layer is covered with the dissociation paper layers with the same size, and the dissociation paper layers at the two ends of the long shaft of the mask main body are peeled off from the surface of the pressure-sensitive adhesive sticking layer and turned over, so that the pressure-sensitive adhesive sticking layers at the two ends of the long shaft of the mask main body are provided with the folding and bonding parts.

Chinese patent documents: CN201320145575.3, application date 2013.03.28, patent names: a duckbill mask. Discloses a duckbill-shaped mask, which consists of an upper single surface of the mask, a lower single surface of the mask, mask elastic bands, a nose bridge line and an inner plastic film sheet; the upper single face of the mask and the lower single face of the mask are the same in shape and size, and are of an inverted trapezoidal structure formed by overlapping two layers of PP anti-sticking non-woven fabric, one layer of melt-blown non-woven fabric of 50g/m2 and one layer of breathable film, a nose bridge line is arranged in the upper single face of the mask, and inner plastic film sheets are adhered to the upper single face and the lower single face of the mask; the upper single face of the mask and the lower single face of the mask are overlapped together, the edges of the rest positions are bonded into a whole except that the upper edge of the inverted trapezoid is not bonded, and two ends of the mask elastic band are bonded at two ends of the opening face of the mask in a natural state without external force.

In the above patent document CN201320653195.0, a bridgeless mask is provided, in which pressure sensitive adhesive layers are bonded to both ends of a long axis of a mask body, and a dissociation paper layer having the same size is coated on the surface of the pressure sensitive adhesive layer, so that the utility model has the advantages of airtightness, air permeability, and water resistance; the mask has the advantages of simple structure, convenient use and comfortable wearing because no fixed lacing or nose bridge clip structure is arranged in the structure, and the mask body has no ventilation valve structure, but the mask also needs to be folded and bonded by a wearer in the use process and is more complex to use; in the duckbill-shaped mask disclosed in patent document CN201320145575.3, the upper and lower surfaces of the mask are respectively adhered with inner plastic film sheets, and the edges of the rest positions are adhered into a whole except that the upper edge of the inverted trapezoid is not adhered, so that the utility model can effectively filter particles in the air and separate spray, blood, body fluid and secretion. The utility model discloses be fit for medical personnel and use, also be fit for numerous public health protection usefulness, but still the design has the elastic cord, so uncomfortable when wearing, the steam that produces when breathing also spills and atomizing eyes through nose line department easily in addition, influences user's sight.

In summary, there is a need for a fully or partially adhesive fixed mask that can be tightly attached to the face of a user, prevent harmful gases from leaking into the nose and mouth from the gap that is not tightly attached to the face, improve the protective effect of the mask, and has a simple structure, and can avoid the structure of the nose bridge, and can partially or completely omit the strap structure, so that the mask is comfortable to wear, and has the function of preventing the breathing water vapor from fogging the eyes or the goggles upwards.

Disclosure of Invention

The utility model aims at overcoming prior art's not enough, provide one kind can closely laminate with user's face, prevent that harmful gas from leaking the inlet port nose side from the space of hugging closely with the face never, improve the protective effect of gauze mask, and use simple structure, removed the bridge of the nose structure from, also can partly or wholly save the lacing structure, wear comfortablely, have simultaneously and prevent the fixed gauze mask of pasting or partly pasting of the wet eyes of breathing fog or goggles.

In order to achieve the purpose, the utility model adopts the technical proposal that:

a full-sticking or partial-sticking fixed mask is characterized in that a fixed mask body comprises an external waterproof layer, a middle filter layer, an internal skin-friendly layer, a pressure-sensitive adhesive sticking layer and a dissociation paper layer; the outer edge of the fixed mask body is of an outwards extending widening structure, and the extending distance is 0.5-1.5 cm; the outer waterproof layer, the middle filter layer and the inner skin-friendly layer are fixedly arranged from outside to inside in sequence; the pressure-sensitive adhesive layer is arranged on the surface of the extended and widened structure outside the fixed mask body; the dissociation paper layer is covered on the surface of the pressure-sensitive adhesive sticking layer.

As a preferred technical scheme, the fixed mask body is of a duckbill-shaped structure folded transversely from top to bottom, a C-shaped structure folded longitudinally from left to right or a planar structure.

As a preferred technical scheme, fixed gauze mask body be horizontal folding duckbilled type structure from top to bottom, and pressure sensitive adhesive pastes the layer and is that the whole circle locates fixed gauze mask body outside extension widen formula structural surface, the gauze mask is opened the back, forms spatial structure naturally.
