TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a hygiene mask, and can be mainly used in the food sales and barber / beauty fields that require hygiene and appeal for hygiene, and in the manufacturing industry of articles that slightly dislike saliva adhesion.
[0002]
[Prior art]
In the past, work was done by putting a face-mounted hygiene mask with filters such as gauze on the face. However, there were many inconveniences such as discomfort peculiar to the mask due to breathlessness, stuffiness and restraint, and inconvenience in keeping makeup, pronunciation and expression transmission, which hindered communication. For this reason, sales performance and work efficiency may be reduced, and in many cases, work is done without a mask in order to simply take care not to spit. In foreign countries, gauze hygiene masks are rarely seen, because gauze does not prevent the invasion of viruses from the outside air and does not originally sterilize it, but rather as a breeding ground for the propagation of various bacteria It is said that there are cases. Although there are other industries such as windshields for helmets that cover the entire face with a transparent plate and dust masks, they are not used as hygiene masks because of the drawbacks of the shape and the weight and cost due to the protective function that covers the eyes.
[0003]
[Problems to be solved by the invention]
In the mouth, there are an average of 100 million bacteria per milliliter of saliva, and every three are said to have Staphylococcus aureus in their nostrils, which causes food poisoning. In addition, it is said that saliva is scattered about 2 meters in a normal conversation, 3 to 5 meters in a cough, and up to 10 meters in a sneeze. Therefore, it is desirable to use a mask, but as described above, the conventional mask imposes a great burden on the wearer both physically and mentally. Rather, there are cases where it is easier to judge harm, freshness and quality by not masking as in the flavor of foodstuffs, or in the case of waiting on customers, even if you have a cold feeling, wearing a mask without wearing a mask and securing conversation and emotional expression. Was. Therefore, if you do not wear a mask, there is a concern about hygiene problems and loss of trust due to saliva if you do not wear a mask, and if you do, work problems due to worker stress, misjudgment and lack of communication may occur. But he had a problem. The present invention has been made in view of the above circumstances, and aims to provide an inexpensive mask that can prevent breath from being blown toward an opposing object on the face and can work with breathing and feeling close to nature. It is.
[0004]
[Means for Solving the Problems]
The transparent face plate and the mounting support attached to the human head are interposed by the connecting portion. The gist is to provide the face plate with a gap in the mouth and nose, and to open the periphery of the gap and the eye to the atmosphere. The position of the face plate was adjusted according to the individual circumstances (A), (B), and (C) in which a transparent plate-shaped part was interposed on the human head.
(A) A mode in which the mounting support is detachably engaged.
(B) A mode in which the head belt and one sheet are formed.
(C) A mode in which the attachment is made to a connecting portion fixed to the head ring.
[0005]
【Example】
FIG. 1 is an overall explanatory view showing a first example of the second embodiment, and is a convenient configuration example when a mask is stored or washed separately from a mounting support (hat). A connecting portion 2 was provided in which the mounting support 1 was locked at the upper end and the face plate 3 was locked at the lower end. The face plate 3 has at least the mouth and nose portions made transparent and the eye portions open. In the present embodiment, as the locking means, the mounting support 1 is detachably attached to the mounting support 1 by using a clip 2a in the form of a clothespin, and the position can be freely adjusted by changing the location and angle of the engagement. The U-shaped leaf spring 2c as seen in document binding is used to clip the front plate 3 and the position can be freely adjusted by sliding. In addition, one or both of the connecting portion 2b and the face plate 3 of the present embodiment are configured to be deformable with a material that is plastically deformed when a condition such as an external force that is not in a normal wearing environment is applied, and further as a means of local deformation. The connecting portion 2b and the clip 2a are pivotally or pivotally mounted in an appropriate braking state.
[0006]
The face plate 3 supported by the above configuration can adjust the relative position with the mounting support 1 according to the face shape when worn, and is provided on the face, and the periphery of the gap is directly opened to the atmosphere for mounting. By doing so, it is possible to prevent breath from being blown toward the opposing object on the face and to obtain breathing and feeling close to nature.
[0007]
Regarding the scope of the present invention, a hat is illustrated as a mounting support in this example, but other examples include a headband, a headband, and a headband, and glasses may be used as the mounting support depending on the size. If there is another means for adjusting the position, the locking means does not necessarily need the function of adjusting the position. Therefore, screwing, vacuum pads, clamps, hooks, or adhesive tapes can also be used as locking means other than the example shown in the drawing, and the present invention only requires that the locking means be detachable from the mounting support. And Although the present embodiment has illustrated various types of position adjustment means, the purpose can be achieved by any single means or an appropriate combination depending on the degree of adjustment amount. Therefore, the present invention is limited to the means shown in the drawings for position adjustment. Not something. Also, the present invention does not specify the position and number of the connecting portions. For example, if the locking portion is soft, the connecting portion 2 is provided on the left and right of the head, and conversely, if the locking portion is rigid, the connecting portion is provided. Only one side of the face can be provided to achieve the purpose.
[0008]
FIG. 2 is an overall explanatory view showing a second example of the second embodiment, which is a simplification of the first example. The face plate 6 locked to the mounting support 4 was extended to the vicinity of the mounting support 4, and at least the mouth and nose were made of a transparent material, the eyes were opened, and conditions such as external force which were not in a normal wearing environment were applied. It is made of a material that sometimes undergoes plastic deformation. In this embodiment, as a locking means, a clip 5a in the form of a clothespin is used to clamp the mounting support 4 and a large number of mesh threads are used as a locking means between the clip 5a and the face plate 6 at the time of connection. A so-called planar fastener 5c that is entangled with the base member 5c is adopted, and a male piece 5d is fixed to the clip 5a, and a female piece 5e is fixed to the face plate 6 in a vertically long manner. In addition, the clipping portion 5c of the clip 5a has a wide mouth and the locking portion is complemented.
[0009]
If the position and angle of the locking are changed and the face plate 6 is plastically deformed by the above configuration, the relative position of the face plate 6 with the mounting support 4 can be adjusted according to the face shape when worn. By mounting the face plate 6 in the face and opening the space around the gap directly to the atmosphere, it is possible to prevent breath from being blown to the opposing object on the face and to obtain breathing and feeling close to nature.
[0010]
The scope of the invention is the same as in the section “0007”. Therefore, instead of the planar fastener 5c of the present embodiment, a rubber disk (not shown) that sucks by contacting with a vacuum by obtaining a vacuum on the contact surface by pressing, or simply a planar surface excluding the clip 5a of the present embodiment is used. An embodiment of the present invention includes a fastener (not shown) using only a fastener or a vacuum pad.
[0011]
FIG. 3 is an overall explanatory view showing an example of the third embodiment, and shows an intermediate state of attachment / detachment of a sheet-shaped mask provided with a portion of the headband portion 7. This is a convenient configuration example in a case where a wide area including a hair part is covered at once or disposable. As shown in the figure, a fence 8 having a transparent mouth and nose 8b and an opening in the eye 8a is provided, and the unfolded form is a substantially flat plate-shaped mask which is formed into a single sheet which can be deformed into a curved shape when worn. . Glue that can be repeatedly adhered is applied in advance to the band ends of the head band portion 7 to form locking means 7a at both ends.
[0012]
When the sheet-shaped mask having the above configuration is formed into a conical partial band shape in accordance with the shape of the individual head when worn, the band end of the head band portion 7 is locked, so that the mask can be worn on the head and a gap formed on the face. It secures and prevents exhalation from being blown to the opposing object on the face, and obtains breathing and feeling close to nature. Flat plates are extremely easy to manufacture, transport, and store, and are low in cost. Curving is advantageous for strength, design, and safety.
[0013]
As a result of conducting a trial production of a transparent plastic having a high elasticity for various thicknesses, a plastic having a thickness of 0.1 to 0.5 mm was good, but there was a difference in a feeling of wearing. That is, although the thing having a thickness of 0.5 mm was rich in rigidity and had a high-grade appearance, it was slightly heavy and sometimes shifted due to inertia when the head was shaken violently. On the other hand, the one having a thickness of 0.1 mm was flexible and cheap, but was not heavy and did not shift. An object having a thickness of 0.1 mm or less was severely deformed by exhalation and was distracted. Therefore, a thickness of about 0.2 mm was determined to be a practical range, depending on the material, shape and working environment. In addition, when the transparent plastic was not used, sweat on the forehead was a concern, but when the untwisted cloth was stuck on the inner periphery of the headband, the discomfort and the slippage due to friction were improved.
[0014]
Regarding the scope of the invention, the present invention does not limit the specific size and decoration of the headband 7. In this example, the earband in which the wavy part 7b is colored as the headband part 7 and a number of small holes 7c are opened in the hearing part is shown. However, depending on the width and decoration, so-called headbands, Japanese hats, cook hats, etc. The design can be made, and if the back of the head is covered in addition to the ears, the scattering of hair is more reliably prevented. Also, `` substantially flat '' means that there are curvatures due to manufacturing convenience, work convenience, design, etc., and even if there are irregularities corresponding to the ear nose part of the face etc. This is a plane within a range that does not extremely hinder production and transportation. The term “deformation” refers to a resultant deformation of a material, and does not distinguish between plastic deformation and elastic deformation. The term "one sheet" includes a form in which a plurality of members are fixed, and the present invention is convenient for manufacturing convenience, working convenience, and design for widespread use. In addition, in addition to the present example, there are many other means for achieving the purpose such as clips, screwing, clamps, vacuum pads, hooks, fasteners, adhesive tapes, staples and the like, and holds the formed conical ring. All the locking means can be adopted as the present invention.
[0015]
FIG. 4 is an overall explanatory view showing an example of the fourth embodiment, and shows a state in which the joint 10 is disassembled. The mounting support and the connecting portion in claim 1 are directly fastened to each other, so that the position adjustment each time a mask is worn is omitted, and the strength is increased to form a single hanging type which is lighter to reduce the feeling of foreign substances when worn. It is a thing. In the illustrated product, a single bent wire 9 is sandwiched between joints 10, and a transparent plate 12 covering the mouth and nose is attached to the underlined portion 9 d by locking means 11. The upper part forms a ring-shaped head ring 9a, has a maximum assumed head diameter in a manufacturing stage, slides the joint 10 with respect to the head ring 9a in the initial stage of wearing, narrows the ring diameter, and adjusts the head diameter to match the head end. 9b is refracted to maintain the ring diameter. In addition, since the torsional rigidity of the wire at the joint 10 is improved as the joining lines are closer to each other, the joining lines are slid up and down in this example. The joint 10 has a structure in which a large number of grooves are formed in the main body 10a, and after the wire 9 is embedded, the lid 10b is fixed by the refraction leaf spring 10c. The connecting portion 9c of the middle wire portion is bent inside the joint 10 after being bent to increase the torsional rigidity. The wire 9 is made of a material that undergoes plastic deformation when a condition such as an external force that does not exist in a normal wearing environment is applied. When a semi-hard steel wire with a diameter of about 2 mm was used for the prototype, local plastic bending requires tools, but gentle plastic bending can be done only by human power, and it is an appropriate material with a displacement amount that does not touch the skin under normal use conditions. Was.
[0016]
The wire rod 9 having the above-described configuration is formed in accordance with the shape of the head and face in the initial stage of wearing, and the face plate 12 is provided on the face, and the periphery of the gap is directly opened to the atmosphere for mounting. Prevents being blown and obtains breathing and feeling close to nature.
[0017]
As to the scope of the invention, in this example, the wire 9 is a single semi-hard steel wire, but the present invention does not specify the material, the cross-sectional shape, or the number, but requires the property of deformation of the material. For example, the cross section does not matter even if it is a tube or a band. In addition, for example, the head ring 9a may be constituted by using a part of the circumference of metal and the remaining circumference of cloth or rubber. In addition, for example, even if the connecting portion 9c is separated from the head ring 9a and configured as a separate component, the object of the present invention can be achieved as long as the connection portion 9c is fixed to the joint 10 or the head ring 9a. In this case, the joint 10 has a different shape from that of the drawing, but it is a requirement of the joint that the joint 10 has at least a function of changing the diameter of the head ring 9a. Therefore, for example, a buckle, a clip, a hook, a fastener, or an elastic cord can also be employed as the joint of the present invention. The locking means 11 requires the mounting of the transparent plate 12 on the underlined portion 9d, and does not limit a specific measure. For example, screwing, vacuum pads, clips, hooks, fasteners, adhesives, and adhesives can also be employed as the locking means of the present invention.
[0018]
FIG. 5 is a partial view of an essential part showing an embodiment of claim 5, wherein the wearer's eyes look down at an example of a locking means of a transparent mask capable of temporarily moving the face plate off during tasting or gargle. It is shown in the state in which it was set. The face plate 15 is mounted on the protruding shaft 14a and is interposed between the board surface 14b and the oblique bar end 13a. When the transparent mask is worn, the outer periphery 15a abuts on the boss 14c as a stopper due to the weight of the face plate 15 at all times. When the shaft 14a is rotated in the reverse direction with respect to the core, a connecting portion is provided in which the turning support 14 is arranged so that the outer periphery 15a moves away from the boss 14c. Also, when an external force which is not in a normal wearing environment is applied, the swash bar 13 slides in the axial direction, so that the contact pressure between the board surface 14b and the swash bar end 13a against the face plate 15 is changed. The oblique bar 13 was fitted into the boss 14c by obliquely intersecting with the shaft of the thirteen. Although not shown, the swivel support 14 is mounted on the mounting surface via a connecting portion that is vertically provided only on one side of the face by means of attaching the board surface 14b to the connecting portion or forming the swash bar 13 itself as a connecting portion. Attach to In addition, the face plate 15 can be always adjusted in position by appropriate means.
[0019]
The wearer of the transparent mask having the above configuration wears the face plate 15 in the mouth and nose with the outer periphery 15a of the face plate 15 in contact with the boss 14c and directly opens the periphery of the gap to the atmosphere. As a result, it is possible to prevent breath from being blown toward the opposing object on the face and to obtain breathing and feeling close to nature. Also, if the face plate 15 slides on the board surface 14b and the swash bar end 13a so that the face plate 15 rotates lightly about the protruding shaft 14a, the finger or the like is touched and the face plate 15 is reversed, and the face plate 15 is temporarily Since it is possible to move away from the garment, it is possible to easily realize a work with a more natural feeling when tasting or gargling.
[0020]
As to the scope of the present invention, the present embodiment shows a structure in which the contact pressure against the face plate 15 is variable by the swash bar 13, but the present invention requires the attachment of the face plate to a shaft and a stopper for rotation. This is a reference example outside the requirements. In addition, there is no particular limitation on the structure of the rotation and the stopper. For example, a rotating structure using a screw, a stud, or a nail, a stopper that can be relocated as a separate component, a stopper having a buffering function, or a stopper that involves light tightening at the time of abutment are also effective as the swivel support of the present invention. Also, in this example, the own weight of the face plate is used as a means for contacting the stopper, but the present invention requires a constant contact that separates by manual operation, and the elasticity of the component parts depends on the turning direction of the face plate and the operational convenience. The present invention can also employ the use of a deformation force, a spring force, or a magnetic force as a means for contacting the stopper.
[0021]
The scope of the invention common to all the embodiments will be described below. First, the “transparent” of the present invention refers to the present invention if the facial expression of the mouth and nose of the mask wearer can be visually recognized even if there is clouding or coloring (so-called translucent) due to manufacturing convenience, working convenience, or design. Within the range. Further, "directly open to the atmosphere" refers to a form in which breathing can be performed without passing through an airflow resistor such as a filter or a ventilation pipe. In addition, it is an invention to provide a twisted cloth etc. on the inner periphery of the mounting support to prevent discomfort of sweat and slippage due to friction, and to apply antibacterial agents, fragrances, antifogging agents etc. to the face plate However, this is not a requirement of the present invention.
[0022]
【The invention's effect】
In conventional sanitary masks such as gauze, the exhalation only weakens the momentum and scatters, and the entire amount is always discharged to the surroundings.Therefore, as in the face plate of the present invention, a complete block of ventilation is in front of the mouth and nose. If it is, there is a more reliable hygiene effect than that of the conventional hygiene mask with respect to the performance of preventing the exhalation and saliva from flying to the opposing object on the face.
[0023]
On the other hand, the air supply / exhaust from the opening around the face plate is a direct ventilation with the atmosphere without passing through an airflow resistor such as a filter or a ventilation pipe, so that the wearer obtains breathing that is almost natural. When wearing it, you may feel a slight air current, but it is so thin that it can be said that there is no discomfort peculiar to the mask due to breathlessness, stuffiness or restraint. In addition, the eyes are open to the atmosphere, so that both odor and sight can be sensed directly.
[0024]
Also, since the mask of the present invention does not come into contact with the skin of the face, there is no makeup loss or pronunciation problems, the movement of the muscles is not restricted by the mask, and since the mouth and nose are transparent, natural expressions and voices can be expressed.・ Can communicate. Therefore, the conversation and the emotional expression between the customer and co-workers are hardly hindered, but rather, it is possible to make the other party feel the care that takes care of hygiene, and to give a favorable impression silently.
[0025]
In terms of cost, it is extremely inexpensive and requires only a small amount of material and simple processing / assembly.
[0026]
As described above, the mask of the present invention has a great effect that is not provided by the conventional hygiene mask. Work difficulties due to lack of communication are greatly reduced, and a “human-friendly work environment” that could not be realized even if money was conventionally used is realized. Conversely, in workplaces where no masks were worn, the masks of the present invention can be adopted without hesitation because they have few disadvantages and are low in cost, and hygiene work that prevents breathing and saliva splashing on the opposing object on the face and external work Can build trust and. In other words, the present invention is a very useful invention that solves contradictory themes at once and improves the hygiene practices of the industry.
