Description

Disaster evacuation wipes {WET TISSUE FOR EMERGENCY ESCAPE}

The present invention relates to a disaster evacuation wipe that can be used as a so-called breathing towel, which is an evacuation handkerchief in disaster situations such as fire.

Wet wipes are used by individuals to conveniently remove foreign substances and contaminants by using wet (water) towels. .

On the other hand, in modern society, in accordance with urbanization caused by industrial development, large-scale architectural structures are built in order to secure insufficient residential and work space in the basement and above ground, and various transportation facilities are provided so that residents can be transported smoothly.

As a result, high-rise buildings and apartments are built in the city center, and a large number of floating people and residents live every day, and subways are being built and operated underground to transport a large number of floating people.

However, most of the underground or above-ground building structures and subways are used by many people for very complex structures and transportation facilities in a narrow space with many residents and floating populations, so special attention and management are required for their use and safety.

In particular, when a fire occurs in the inner space of a building structure underground or above ground, it is not easy to secure visibility due to the toxic gas generated from the building materials. It is not easy to evacuate, and if the toxic gas fills the room in an instant, the evacuees feel difficulty in breathing and suffocate because they cannot evacuate quickly. According to statistics, more than 90% of the biggest loss of life in a fire is due to asphyxiation.

In the event of a fire, there is no way to prevent suffocation due to toxic gas, and there is a problem in that there is only a room for evacuees to evacuate by covering their mouths with their hands or handkerchiefs and clothes, etc.

The best way to evacuate the floating population in case of a fire is to have enough gas masks to be worn by all the floating people in the building structure. However, to provide a gas mask at each site according to the large number of floating population in a large city, the equipment cost is very high, and it takes a large space to provide the equipment at each site, so it is not a realistic method.

Currently, the site is equipped with a certain number of gas masks for a small number of people who will lead the evacuation, and a large number of towels and water bottle sets for a large number of evacuees. cover them with a towel and evacuate.

However, the above-described equipment for a large number of evacuees also occupies a considerable amount of loading space by separately providing towels and water bottles, and the effect of blocking toxic gas was low compared to the cost.

The present invention proposes a disaster evacuation wipe that is used as a so-called breathing towel, which is an evacuation handkerchief, in disaster situations such as fire, and is used for a similar purpose to general wipes after evacuation.

The above-described objects, features and advantages will be described below in detail with reference to the accompanying drawings, and accordingly, those skilled in the art to which the present invention pertains will be able to easily implement the technical idea of the present invention. In describing the present invention, if it is determined that a detailed description of a known technology related to the present invention may unnecessarily obscure the gist of the present invention, the detailed description will be omitted.

In the drawings, the same reference numerals are used to refer to the same or similar elements, and all combinations described in the specification and claims may be combined in any manner. And unless otherwise specified, it is to be understood that references to the singular may include one or more, and references to the singular may also include the plural.

The terminology used herein is for the purpose of describing specific exemplary embodiments only and is not intended to be limiting. As used herein, singular expressions may also be intended to include plural meanings unless the sentence clearly indicates otherwise. The term “and/or” includes any and all combinations of the items listed therewith. The terms "comprises", "comprising", "comprising", "comprising", "having", "having" and the like have an inclusive meaning, so that these terms refer to their described features, integers, It specifies steps, operations, elements, and/or components and does not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

Figure 1a shows a folded state of the disaster evacuation wipes according to an embodiment of the present invention. The wet tissue of the illustrated embodiment is in the illustrated folded state when the sealing packaging material is peeled off, so that the evacuator can use it by directly covering his or her breathing apparatus (oral and nasal passages).

Figure 1b shows a state before and after folding of the disaster evacuation wipes according to an embodiment of the present invention. The wet wipes of the illustrated embodiment are unfolded in a state in which the simple coupling part (to be described later) is released, and after evacuation, the user unfolds the wipes to remove contaminants on the body, clothes, and portables in a disaster evacuation environment.

The illustrated disaster evacuation wipes include: a sheet laminate in which the unit sheet 20 is folded at least twice to cover the oral cavity of a person; a filter solution impregnated in the sheet laminate; And it may include a simple coupling portion 60 that combines a portion of the corners of the sheet laminate with a bonding strength that allows the user to intentionally peel the sheet laminate without peeling off while covering the oral cavity of the person.

The sheet stack of the disaster evacuation wipes shown is 300mm in width and 600mm in length when unfolded. First, fold in a zigzag shape in the vertical direction in the shape of a corrugated door, and then fold in half again in the horizontal direction. have. As a result, the final length of the wet tissue after all folding may be 150mm horizontally and 100mm vertically.

For a sufficient blocking effect against toxic gases generated in disaster situations such as fire, it is preferable that the grid planes of the unit sheet 20 overlap at least six surfaces in the intake direction in the sheet laminate. In the case of the illustrated sheet laminate, 12 grid planes are overlapped.

It is preferable in terms of cost and storage that the filter solution is purified water that does not deteriorate during long-term storage. On the other hand, in order to increase the blocking efficiency of toxic gas, a biocompatible / eco-friendly natural surfactant aqueous solution may be applied to the filter solution for the adsorption of fat-soluble molecules as well as the adsorption of water-soluble molecules.

For example, as the natural surfactant aqueous solution, a mixed aqueous solution of bamboo vinegar may be applied. Bamboo vinegar is an acidic liquid with acetic acid as its main component. It has very similar ingredients and color to vinegar, but vinegar is made by decomposing carbohydrates such as starch in grains with enzymes, whereas bamboo vinegar liquid is liquefied smoke from the process of making bamboo charcoal. After that, it is obtained by removing toxic and harmful substances.

In addition to acetic acid, which is the main component, bamboo vinegar contains about 200 kinds of natural ingredients such as alcohol, ester, aldehyde, and ketone. Acetic acid softens or contracts the dead skin cells on the skin surface, and alcohol has a sterilizing action to clean the skin. The aldehyde component has excellent permeability and is used as an ingredient in cosmetics. Above all, the acetic acid, alcohol component and aldehyde component increase binding to fat-soluble molecules contained in combustion gas, thereby effectively blocking the fat-soluble poisonous gas from breathing air.

In addition, even if the purified bamboo vinegar is stored for more than one month, E. coli or general bacteria are not detected at all, so it can be seen that the purified bamboo vinegar has a function of inhibiting growth of bacteria itself. Therefore, the inclusion of bamboo vinegar has the advantage of extending the shelf life (ie, storage period) of the disaster evacuation wipes.

For example, as the aqueous solution of the natural surfactant, a mixed aqueous solution of a natural extract containing at least one of Yeongyo extract, baeja extract, and grapefruit extract may be applied.

For example, based on 100 parts by weight of purified water, 1 to 5 parts by weight of the yeonkyo extract, 1 to 3 parts by weight of the pear extract, and 1 to 2 parts by weight of the grapefruit extract.

The natural extract is harmless even if a microscopic amount is introduced into the digestive system or respiratory tract, and by increasing the binding property to the fat-soluble molecules contained in the combustion gas, it is possible to effectively block the fat-soluble poisonous gas from the breathing air.

The simple coupling portion 60 is, when the user pulls the user to forcibly separate with a weak force while evacuating, while the user covers the lower face including the oral cavity with his or her hand and has sufficient bonding strength so that the coupling is not disassembled during movement It is provided to have a bonding strength that is easily dismantled.

For example, the simple coupling part 60 is a thread having strength that can be cut with a human finger at a point where the corners of the unit sheet 20 meet each other in the folded state of the unit sheet 20 as described above. It may be a sewing unit (overlock unit) sewn several times. In the drawings, two sewing units are expressed as an example.

For example, the simple coupling part 60 may be an ultrasonic welding part formed by applying ultrasonic waves to a point where the corners of the unit sheet 20 meet each other in the folded state of the unit sheet 20 as described above.

In addition, in order to ensure sufficient bonding strength and intentionally separable bonding strength during the evacuation described above, the simple bonding portion 60 has a suitable number of bonding points (two in FIG. 1A) for one sheet laminate. should have

For example, at a point where the corners of the unit sheet meet each other, 2 to 5 sewing units or ultrasonic welding points may be provided. Intentional separation is easy while preparing for a case in which a defect exists in one sewing part or ultrasonic fusion point during the manufacturing process or one sewing part or ultrasonic fusion point is separated in the packaging/delivery process.

For example, in the case of an implementation in which both outer surfaces of the sheet laminate have an envelope shape containing the rest of the folded sheet surfaces inside, two to five sewing units or ultrasonic fusion points are formed on the open sides of the envelope shape. It may be formed in such a way that the shape is closed.

Next, a preferred material of the unit sheet 20 will be described.

The unit sheet 20 may be implemented with any fabric or non-woven fabric used for conventional handkerchiefs or wet wipes.

However, the wet tissue used as a breathing towel is contaminated with a large amount of various pollutants in the process of blocking toxic gas and wiping off pollutants, making it difficult to reuse. can cause Therefore, the remaining disposal/treatment method is landfill, but chemical materials such as PE and acetate, which are widely used as wet wipes, take a very long time to decompose naturally during landfill, which may cause environmental problems.

As a solution to the above-mentioned problems, the present invention provides, as a material of the unit sheet 20, a pulp (fiber constituting the plant) made of vegetable fiber, particularly, a natural fiber derived from grass or tree trunk, which is inexpensive to manufacture. It is preferable that they are extracted and collected).

In view of harmlessness to the human body upon inhalation, manufacturing cost, sufficient strength as a breathing towel, and securing sufficient pores, it is preferable that the nonwoven fabric is made of bamboo fibers made of natural fibers physically extracted from bamboo.

The bamboo fiber nonwoven fabric can be manufactured by various methods, and the sheet of the present invention is not limited to a specific method for manufacturing the bamboo nonwoven fabric. For example, traditionally, evenly cut bamboo is crushed and pressed, soaked in lime water for several months, then the pulp from the bucket is pulled out through a wooden frame, and the skillful process of removing and drying each piece is repeated until a smooth paper form is obtained. Like the manufacturing method, it may be manufactured similarly to the manufacturing process of Korean paper.

On the other hand, as a method suitable for automation/mass production, the first step is to remove the leaves from the bamboo, cut and cut the bamboo, or use a drum chipper to produce chips of uniform thickness, and the second step is screening. The washing step, the pulping step as the 3rd step, the dust removal step of centrifugally removing foreign substances as the 4th step, and the 5th step are the cleaning steps to remove foreign substances using a pressure screen, and to put the less cooked part back into the cooking section It may be prepared as a step, a sixth step of washing the chemical solution from the pump using a decker, a washing and concentration step of squeezing out water to concentrate, a bleaching step as a seventh step, and a nonwoven fabric manufacturing step as an eighth step.

2a to 2c show packaging materials (1000, 2000, 3000) containing the disaster evacuation wipes according to the spirit of the present invention.

When the user cuts the packaging material along the cutting guide means 1005, 2005, 3005 of the packaging material 1000, 2000, 3000, the wet tissue is opened in a state in which it is folded as shown in FIG. can be In a disaster situation, the user can block the toxic gas by directly cutting the packaging material and attaching the breath towel obtained directly to the lower part of the face. Since the wet tissue of the present invention is contained in the packaging material impregnated with the filter solution, it is possible to immediately block the toxic gas without a separate operation such as pouring water from the bottled water.

It can be seen that the illustrated packaging materials 1000 , 2000 , and 3000 are provided with cutting guide means 1005 , 2005 and 3005 on all four sides of the rectangular packaging. Accordingly, in an emergency situation, even if the user holds the breathing towel contained in the packaging material in any form, the packaging material (1000, 2000, 3000) is immediately opened so that the breathing towel can be obtained.

On the other hand, in the case of FIGS. 2A and 2B, the cutting guide means 1005 and 2005 are formed on both ends of each side of the rectangular pavement, which reflects that the inner wet tissue may be damaged when the package is opened in the middle of the side. On the other hand, in the case of FIG. 2C , the cutting guide means 3005 is formed in the central area of each side of the rectangular pavement, so that even if the user hastily grabs it in an emergency situation, it supports the smooth unpacking.

Figure 3a shows an unfolded state of the disaster evacuation wipes according to another embodiment of the present invention, Figure 3b shows a folded state. Hereinafter, circled numbers in the drawings indicate the folding order during packaging. In the case of the wet tissue according to the illustrated embodiment, a wet tissue that can be a breathing towel having a mask shape for easy wearing and movement is proposed.

The illustrated disaster evacuation wet tissue is a wearing part 140 that fixes the sheet stacked body shown to the lower part of the person's face when worn by the user, and an earring string that can be fixed to the user's ear, and the earring string is attached to the unit sheet ( It further includes a wearing part attachment means 180 for attaching to the upper surface of the 120). The wearing part attachment means 180 may be, for example, a result of sewing or ultrasonic welding.

On the other hand, the illustrated unit sheet 120 is folded 5 times in the same direction on one side to constitute 6 layers, and in the final folding, a simple coupling part 160 made of two sewing parts or ultrasonic fusion points is formed on the opposite side of the folded side. formed.

Figure 4a shows an unfolded state of the disaster evacuation wipes according to another embodiment of the present invention, Figure 4b shows a folded state. In the case of the wet tissue according to the illustrated embodiment, a wet tissue that can be a breathable towel having a mask shape is proposed for easy wearing and movement, and a pleated type that alternates folding in and out in folding the unit sheet 220 It has the advantage of being able to quickly unfold when the user uses it as a wet tissue.

On the other hand, none of the four sides of the sheet laminate can be shaped to cover the entire layer, so a simple coupling part 260 made of a sewing part or ultrasonic fusion point is formed on all four corners of the sheet laminate. That is, a relatively large number of minimum required sewing units or ultrasonic welding points is required compared to other embodiments.

Figure 5 shows the unfolded state of the disaster evacuation wipes according to another embodiment of the present invention. In the case of the wet tissue according to the illustrated embodiment, both outer surfaces [1] and [2] of the sheet laminate are left on the rest of the sheet stack so that the user can quickly dismantle it for use as a wet tissue while helping to maintain the shape when used as a breathing towel. A structure in the shape of an envelope containing the sheet surfaces [3 to 6] constituting the inner lattice of the folded unit sheet 320 is proposed.

Compared with the previous embodiments, both outer surfaces [1] [2] of the sheet laminate serving as an envelope have a slightly larger area than the sheet surfaces [3-6] of other grids, so that the manufacturing process is slightly It can be cumbersome. However, when forming the simple coupling part 360 by a method such as sewing or ultrasonic welding, only both outer surfaces [1] [2] of the sheet laminate are bonded to each other and the sheet surfaces of other grids [3 to 6] is not combined, so it has the advantage of being able to dismantle (unfold) quickly. On the other hand, in the case of the previous embodiments, the unit sheet surfaces of all the grids are combined with each other by sewing or ultrasonic welding, etc., so the dismantling operation is rather difficult.

Figure 6 shows the unfolded state of the disaster evacuation wipes according to another embodiment of the present invention.

As in the case of FIG. 5, the disaster evacuation wipe shown in FIG. 6 also has an area of the lattice plane [1] [8] that becomes the 2 outer surfaces of the breathing towel in the folded state is slightly larger than the other grids, and accordingly the 2 outer surfaces is a kind of envelope shape, and it can be seen that the other grids [2 to 4] [5 to 7] are folded in a form that is accommodated inside the formed envelope.

As described above, the disaster evacuation wipe according to the spirit of the present invention has a relatively simple and inexpensive structure, but supports rapid wearing when used as a breathing towel in a disaster situation, and provides a sufficient blocking effect for the generated toxic gas. .

In order to maximize the effect of blocking toxic gas generated in disaster situations such as fire, a substance for filtering toxic gas may be added to the unit sheet itself constituting the disaster evacuation wipes. For example, the unit sheet may include zeolite and/or activated carbon particles.

The zeolite and activated carbon particles have micropores that widen the contact area with air, so they can adsorb toxic substances in the form of ultra-fine dust and ultra-fine dust, and can also adsorb toxic molecules themselves, which is effective in blocking toxic gas am.

Depending on the embodiment, the zeolite and/or activated carbon particles may be evenly distributed on the unit sheet or may be added to only a partial region of the unit sheet. In the former case, there is an advantage in that the manufacturing process is simple, and in the latter case, there are advantages in material cost reduction and securing the function of the contaminant removal wipes. In the former case, since the structure is simple, it can be applied to the above-described embodiments without additional explanation. Embodiments in the latter case will be described in detail with reference to the following drawings.

Figure 7a shows the unfolded state of the disaster evacuation wipes according to another embodiment of the present invention, Figure 7b shows a folded cross-section.

The unit sheet 620 of the embodiment shown in FIG. 7A has a form in which zeolite is added to the left grids [1 to 4] and activated carbon is added to the right grids [9 to 12], and the unit sheet 620 When folded to form a breath towel having 12 layers, the laminated structure of the cross-section is shown in FIG. 7b.

As shown in FIG. 7B , each sheet of grids 692 to which zeolite is added and each sheet of grids 694 to which activated carbon particles are added alternate with each other, so that various types of harmful molecules are included. The gas blocking effect can be increased.

On the other hand, by locating the zeolite addition region 692 of the unit sheet 620 on the left side and the activated carbon addition region 694 on the right side, the complexity of the process of partially adding different particles can be reduced as much as possible. have.

Figure 8a shows the unfolded state of the disaster evacuation wipes according to another embodiment of the present invention, Figure 8b shows a folded cross-section.

In the unit sheet 720 of the embodiment shown in FIG. 8A, zeolite is added to the upper lattices [1] [6] [7], and activated carbon is added to the lower lattices [3] [4] [9] And, the laminated structure of the cross-section when the unit sheet 720 is folded to form a breath towel having 9 layers is shown in FIG. 8b.

As shown, each sheet of the grids 792 to which zeolite is added and each sheet of the grids 794 to which activated carbon particles are added alternate with each other, so that toxic gas containing various types of harmful molecules is blocked While increasing the effect, the complexity of the process of partially adding different particles can be reduced as much as possible.

It should be noted that the above-described embodiment is for illustrative purposes only, and not for its limitation. In addition, those skilled in the art will understand that various embodiments are possible within the scope of the technical idea of the present invention.
