Description

Strapless mask and method for manufacturing the same

The present invention relates to a mask without ear straps and a method of manufacturing the same, and more particularly, a mask without ear straps, including an accessory band for wearing a mask that is detachably coupled with the mask body and can be used semi-permanently, and the same It relates to a manufacturing method.

Recently, in order to prevent the spread of the novel virus Corona-19, each individual wears a mask.

In other words, since the only option to protect individual lives by blocking transmission by droplets referred to as the path of infection of viruses such as Corona-19, masks are essential for each individual.

Therefore, since it is required to wear a mask until the development of a new drug vaccine is developed after the virus outbreak, there is a phenomenon that the supply of manufacturing the mask in the production plant cannot keep up with the demand for the mask.

In general, the mask is composed of a mask body that covers the face under the eyes, and ear straps integrally connected to both side ends of the mask body through a thermocompression process.

In the mask production process, the mask body may be repeatedly produced hundreds to thousands of sheets for a certain period of time, but there is a problem in that the process of thermocompressing the ear straps to the mask body takes a long time.

Moreover, as the both ends of the ear straps are thermally compressed on both sides of the mask body, a total of four thermal compressions are required, so that the process of thermally compressing the ear straps to the mask body is inevitably performed more slowly.

For example, the production speed and quantity of the mask body coming out of the mask body manufacturing machine of the mask production line is about three times faster than the quantity and working speed of heat bonding the ear straps, resulting in a delay in the mask production speed. Inevitably, the mask production efficiency is inevitably reduced.

Accordingly, if up to three ear string thermal bonding machines are placed on the mask production line compared to one mask body manufacturing machine, the mask production speed can be improved, but the mask manufacturing cost can be greatly increased due to additional arrangement of production facilities.

In addition, since the surface of the mask body becomes contaminated when the mask composed of the mask body and ear straps is worn several times, most of the mask is discarded as it is, and thus, environmental pollution problems due to the disposal of the mask may occur.

That is, although the surface of the mask body constituting the mask is properly discarded because it is in a contaminated state, even the ear straps are discarded as it is, which is inefficient in terms of resource recycling.

Moreover, since a rubber band for providing elasticity is embedded inside the ear straps constituting the existing mask, there is a problem of causing environmental pollution because it does not rot if discarded as it is.

As an example of the prior art, Publication No. 10-2019-0132620 discloses a mask in which a fashion design is combined, and a mask in which various fashion designs or functional designs are combined on the front surface of the mask is disclosed.

As another example of the prior art, Publication No. 10-2017-0043858 discloses that a blank mask and a photo mask using the same, as a material forming a hard film, capable of reducing the damage of the lower light-shielding film during the photomask manufacturing process. have.

As another example of the prior art, registration number 10-2107161 discloses a length string connection mechanism of a mask to provide a convenient function of reducing the string through a bonding process with the mask body.

However, the above-described prior art and other mask-related technologies are mostly technologies that advocate fashion design or have a convenience function to reduce ear straps, and are limited to a technology for producing a mask including ear straps.

In addition, the binding mechanism 40 may be adopted as a variety of binding mechanisms such as tongs and Velcro tape.

Preferably, when molding and manufacturing the accessory band 20 for wearing the mask, the acupressure protrusion 22 is integrally protruded on the local surface, and the acupressure protrusion 22 is an earring part by wearing a mask. When fatigue is accumulated, the ear is pressed or rubbed to help blood circulation.

Meanwhile, as shown in FIGS. 5A to 5E, an accessory 30 for length adjustment is further inserted into the accessory band 20 for wearing a mask.

The length adjustment accessory 30 is manufactured in a plate body structure in which the accessory band 20 for wearing the mask is inserted and two or more band length adjustment holes 32 passing through it are formed.

Accordingly, the desired wearing length of the accessory band 20 for wearing a mask is adjusted by holding and pulling the accessory band 20 at the portion passing between the band length adjustment holes 32 of the length adjustment accessory 30. Can be.

In particular, the length adjustment accessory 30 is manufactured in a structure in which various characters are printed on a plate body made in any one shape selected from heart-shaped, circular, square, and elliptical as shown in FIG. 6, thereby making it an accessory fashion product. It can be actively used for corporate promotion advertisements as it creates new trends and can selectively print various shapes and designs.

Therefore, when the user wants to wear a mask, after binding the mask-wearing accessory band 20 to the mask body 10 without ear straps manufactured as described above using the above-described type of binding mechanism 40, The mask body 10 is in close contact with the face and at the same time, the accessory band 20 can be hung on the ear and used usefully.

On the other hand, when the mask body 10 is contaminated due to wearing for a certain period, the user releases the binding mechanism 40 from the mask body 10 to separate the mask accessory band 20 and the length adjustment accessory 30. Accordingly, the user can discard the mask body 10 as it is, and the separated mask-wearing accessory band 20 and the length adjustment accessory 30 can be reused semi-permanently, such as binding again to a new mask body.

As seen above, by discarding only the mask body 10 and reusing the accessory band 20 for wearing the mask, it is possible to prevent environmental pollution caused by discarding the mask with ear straps as it is, and is efficient in terms of resource recycling. It can provide an advantage.

In addition, the accessory band 20 for wearing a mask is provided with various binding mechanisms (tick buttons, hooks, rotation pins, tongs, etc.) for binding with the mask body 10 to make it a single product and sell it to increase consumer purchase desire. And economic revitalization, and the length adjustment accessory 30 is also manufactured in various shapes (heart type, circle, square, oval), and at the same time, various patterns and characters are printed on the surface and sold as a single product. By making it possible, it can contribute to the increase of consumer purchase desire and creation of added value.

On the other hand, the anti-pollution coating layer made of an anti-pollution coating composition may be applied to the accessory band 20 for wearing a mask so as to effectively prevent adhesion and removal of contaminants.

The antifouling coating composition contains cocoamphodiacetate and alkyl glycol ether in a molar ratio of 1:0.01 to 1:2, and the total content of cocoamphodiacetate and alkyl glycol ether is 1 to 10% by weight based on the total aqueous solution. to be.

The molar ratio of the cocoamphodiacetate and the alkyl glycol ether is preferably 1:0.01 to 1:2. If the molar ratio is out of the above range, the applicability of the accessory band 20 for wearing a mask decreases or the surface moisture after application There is a problem that the coating film is removed due to increased adsorption.

The cocoamphodiacetate and alkyl glycol ether is preferably 1 to 10% by weight in the total aqueous solution of the composition, and if it is less than 1% by weight, there is a problem that the applicability of the accessory band 20 for wearing a mask is degraded, If it is exceeded, crystal precipitation is likely to occur due to an increase in the coating film thickness.

On the other hand, as a method of applying the present antifouling coating composition on the accessory band 20 for wearing a mask, it is preferable to apply it by a spray method. In addition, the thickness of the final coating film on the accessory band 20 for wearing a mask is preferably 550 to 2000 Å, more preferably 1100 to 1900 Å. When the thickness of the coating film is less than 550 Å, there is a problem of deterioration in the case of high-temperature heat treatment, and when it exceeds 2000 Å, crystal precipitation on the coated surface is liable to occur.

In addition, the present antifouling coating composition may be prepared by adding 0.1 mol of cocoamphodiacetate and 0.05 mol of alkyl glycol ether to 1000 ml of distilled water, followed by stirring.

In addition, the length adjustment accessory 30 may be coated with a fragrance material mixed with a functional oil that helps in sterilization and stress relief.

The mixing ratio of the perfume material and the functional oil is 95 to 97% by weight of the perfume material and 3 to 5% by weight of the functional oil is mixed, and the functional oil is 50% by weight of Conifer note oil, and Wormwood oil. oil) 50% by weight.

Here, the functional oil is preferably mixed in 3 to 5% by weight based on the fragrance material. When the mixing ratio of the functional oil is less than 3% by weight, the effect is insignificant, and when the mixing ratio of the functional oil exceeds 3 to 5% by weight, the effect is not greatly improved, while the manufacturing cost is greatly increased.

Conifer note oil is good for neuralgia, muscle pain, antidepressant, and stress relief.

Wormwood oil has excellent effects on detoxification, treatment of skin diseases, sterilization, relief of itchiness, clearing of the head, and relaxation of tension.

Therefore, as the perfume material mixed with such a functional oil is coated on the length adjustment accessory 30, effects such as sterilization treatment of the length adjustment accessory 30 and reducing operator fatigue can be obtained.

The reason for limiting the constituents and limiting the numerical value of the mixing ratio for the fragrance substance and the functional oil is that the present inventors have repeatedly failed several times and analyzed through the test results. Is shown.

In addition, a corrosion-resistant coating layer may be applied to the knife 110 for forming the first incision part to prevent corrosion of the metal surface.

The coating material of this anticorrosive coating layer is triethanolamine 15% by weight, indiazole 25% by weight, hafnium 20% by weight, molybdenum emulsified (MoS ² ) 10% by weight, titanium oxide (TiO ² ) 15% by weight, propionamide 15% by weight It is composed of %, and the coating thickness can be formed to 8㎛.

Triethanolamine, indiazole, and propionamide play a role in preventing corrosion and discoloration.

Hafnium is a transition metal element with corrosion resistance and plays a role in having excellent waterproof and corrosion resistance.

Molybdenum emulsified plays a role of imparting wetness and lubricity to the surface of the coating film.

Titanium oxide is added for the purpose of fire resistance and chemical stability.

The reason why the ratio of the constituent components and the coating thickness were numerically limited as described above is that the present inventors analyzed through the test results while repeatedly failing several times, and as a result, the optimum anti-corrosion effect was exhibited at the ratio.
