Summary of the Invention

Problems to be Solved by the Invention

[0004] However, the places where such toxic gas masks are placed are limited, such as workplaces, and it is difficult to be useful when needed as they are not close at hand.

[0005] Therefore, the inventor noticed that many people always keep their smartphones close at hand and can use them immediately, and discovered the possibility that the notebook-type smartphone cases in FIGS. 1 and 2 can be used as a smoke mask and a gas mask in case of a fire. Here, 10 is a smartphone, and 1' is a notebook-type smartphone case.

[0006] An object of the present invention is to provide a notebook-type smartphone case having a smoke mask and a gas mask function in view of the above problems of the conventional technology.

Means for Solving the Problems

[0007] The first aspect of the present invention is A notebook-type smartphone case that has a case function for smartphones and can be folded left or right or up or down, One or more sheets are rotatably mounted at designated locations inside the case. A face rest portion is formed using the surface of one sheet, the surfaces of multiple sheets together, or the surface of the sheet and the inner surface of the main part of the case. By pressing the aforementioned notebook-type smartphone case against the face while it is open, the face-support portion can cover at least the nose and mouth of the user's face. The aforementioned face covering portion has an enclosure member, The enclosure member is attached to only one sheet, or across the surfaces of multiple sheets, or across the surface of the sheet and the inner surface of any of the main parts, and can be positioned in an upright or reclining position. The aforementioned enclosure member has a folding structure, and is characterized by being able to lie flat when used as a smartphone case and stand up when used as a smoke or gas mask.

[0008] The second aspect of the present invention is: The enclosure member is attached across the surfaces of the multiple sheets or across the inner surface of the main part of either the surface of the sheets or the case, and has a V-fold folding structure centered on the boundary line between those surfaces, and when the sheets are opened, the enclosure member automatically stands upright, in the first notebook-type smartphone case of the present invention.

[0009] The third invention is, The enclosure member is attached only to the single sheet. The first notebook-type smartphone case of the present invention is characterized in that the surface of the sheet to which it is attached is the inner surface of the main part of the case that does not face the inner surface in which the smartphone is mounted.

[0010] The fourth aspect of the present invention is: The first to third notebook-type smartphone case of the present invention is characterized in that an air intake portion is provided in a part of the main part of the notebook-type smartphone case, or in a part of the enclosure member or the sheet.

[0011] The fifth aspect of the present invention is: The fourth version of the present invention is a notebook-type smartphone case, wherein the air intake section has a filter layer or filter member capable of filtering out smoke and toxic gases. [Effects of the Invention]

[0012] The first aspect of this invention makes it easy to convert a readily available notebook-style smartphone case into a smoke and gas mask in case of fire. Furthermore, because a sheet can be used, it is convenient for various unusual types of notebook-style smartphone cases as well, as the surrounding material does not get in the way when the smartphone is inserted and used.

[0013] The second aspect of this invention is that the enclosure member automatically rises up simply by opening the sheet, allowing for effective response even in a panic during a fire.

[0014] The third aspect of the present invention minimizes the risk of interference between the mounted smartphone and the enclosure member.

[0015] The fourth aspect of this invention is that it does not cause suffocation because it has an air intake.

[0016] The fifth aspect of this invention is that clean air can be taken in through filtering. [Brief explanation of the drawing]

[0018] Hereinafter, embodiments of the notebook-type smartphone case of the present invention will be described with reference to the drawings.

[0019] Figure 3 is a partial perspective view of a foldable notebook-type smartphone case in an embodiment of the present invention, with the enclosure member omitted. Here, one side of a sheet 52 is rotatably attached to a predetermined location inside the case 1'. In this example, the rear side 52b of the sheet 52 is rotatably attached to a basic fold line 53 located at the connection point between the inner surface 50a of the left main part 50 of the case 1' and the inner surface 50b of the right main part 50. A smartphone mounting member 51 is attached to the right inner surface 50b of the main part 50, and a smartphone can be mounted there. Note that the mounting position of the rear side 52b of the sheet 52 is not limited to the basic fold line 53; it may be offset, or it may be rotatably attached from the middle of the inner surface of the main part 50, or, as will be described later, it may be rotatably attached perpendicular to the line of the basic fold line 53, rather than parallel to it.

[0020] 54 are hook-and-loop fasteners provided at the four outer corners of the inner surface 50a of the left main part 50 of case 1' and the inner surface 50b of the right main part 50, and also at the corresponding four outer corners of the front and back surfaces of the sheet 52. Normally, the sheet 52 does not open, but in an emergency, it can be opened by hand. A smartphone mounting component 51 is attached to the inner surface 50b of the right main part 50, and it is desirable that the hook-and-loop fastener 54 on the sheet 52 at the corresponding position on the inner surface 50b of the right main part 50 attaches the sheet 52 to the hook-and-loop fastener 54 on the inner surface 50b of the right main part 50 when opening the sheet 52 in an emergency. This prevents the sheet 52 from attaching to or detaching from the inside when escaping from a fire.

[0021] Furthermore, the mounting position of the hook fastener 54 on the side of the main part 50 where the smartphone mounting member 51 is located may be positioned above the portion of the smartphone mounting member 51. The number and position of these fasteners are arbitrary.

[0022] Alternatively, the height of the hook-and-loop fastener 54 on the side of the main part 50 where the smartphone mounting member 51 is located may be increased so that when the sheet 52 is opened, even with the smartphone still mounted, the sheet 52 adheres firmly to the smartphone mounting member 51. As will be described later, one of the effects of having a higher hook-and-loop fastener 54 is that when the sheet 52 is opened, a gap is created between the sheet 52 and the inner surface 50b on the side of the main part 50 where the smartphone mounting member 51 is located, allowing air to enter and exit smoothly.

[0023] Figure 4 is a schematic perspective illustration of a partial embodiment of the present invention. Case 1' is opened, and the sheet 52 is further opened, so that the inner surface 50a of the main left part 50 and the left surface 52a of the sheet 52 are almost flush.

[0024] In this state, the enclosure member 2 automatically stands upright, as will be described later. In Figure 4, the thick line indicates the upper edge of the enclosure member 2 in its upright position. In this upright position, the enclosure member 2 can be placed against the face to help with smoke and gas protection.

[0025] A detailed explanation of the enclosure member 2 will be given based on Figures 5, 6, and 7. Specifically, the enclosure member 2 is formed by upper and lower members 2c, 2c and left and right members 2d, 2d, creating a continuous enclosure. Note that the enclosure member may be composed of other types of members besides these two.

[0026] Figure 5 shows the enclosure member 2 in a folded, lying-down state when sheet 52 is closed, with the left and right parts overlapping. Sheet 52 is omitted in the figure. When sheet 52 is opened, the enclosure member 2 automatically rises up, as shown in Figure 4.

[0027] Figure 6 shows the enclosure member 2 broken down into four parts. Specifically, members 2c, 2c are drawn vertically, and members 2d, 2d are drawn horizontally.

[0028] In this embodiment, the upper and lower members 2c are V-fold (diagonal fold) members centered on the boundary line between the inner surface 50a of the left main part 50 and the left surface 52a of the sheet 52. That is, the bottom edge 2c2 of the member 2c is cut in a V-shape in a planar state, and the lower end of the V-shape coincides with the basic fold line portion 53 described above. In other words, the V-fold is achieved by bonding the right side of this V-shaped bottom edge 2c2 to the surface of the sheet 52, and the left side of the bottom edge 2c2 to the inner surface 50a of the main part 50.

[0029] This V-fold fold itself is well known from pop-up books and the like. With this V-fold structure, when the sheet 52 is opened, the upper and lower members 2c automatically stand up.

[0030] Next, let's explain the left and right members 2d, 2d. Each has a slender trapezoidal shape. The upper and lower (on the drawing) hypotenuse 2d2 of the trapezoidal shape connect to one of the left and right sides 2c1 of the upper and lower members 2c.

[0031] In Figure 7, the right side shows the state where the hypotenuse 2d2 of the right member 2d is connected to the right side 2c1 of the upper member 2c, and the left side of Figure 7 shows the state after the connection, where the left member 2d is folded inward at one side 2c1.

[0032] In Figure 6, the angle B of the upper and lower members 2c and the angle A of the left and right members 2d coincide, but are not limited to this. Angle B is the angle made by one side 2c1 with respect to the imaginary line K parallel to the basic broken line 53. Angle A is the angle made by the hypotenuses of the trapezoids formed by the left and right members 2d.

[0033] Furthermore, in Figure 6, 2d1 of the left and right members 2d indicates a fold. When the upper and lower members 2c automatically stand up, the left and right members 2d connected to them are also pulled and try to stand up. At this time, it is desirable to have folds 2d1 on the left and right members 2d so that they can easily fold outwards. This allows the folds 2d1 to deform outwards as they fold, releasing the tension (stiffness) in the left and right members 2d when they stand up, preventing them from standing up folded inwards.

[0034] Furthermore, in order to prevent wrinkles or excessive force from forming in such shapes and arrangements, it is desirable to use materials with flexible elasticity.

[0035] In this embodiment of the present invention, when using the smartphone, the sheet 52 is attached to the inner surface 50a of the main left part 50 of the case using the hook-and-loop fastener 54. Therefore, the enclosure member 2 is in a folded, lying-down state. In this state, the sheet 52 covers the enclosure member 2 and does not interfere with the use of the smartphone.

[0036] In this state, if a fire breaks out, opening the sheet 52 will automatically raise the enclosure member 2, immediately providing gas protection and smoke protection. At that time, the sheet 52 is attached to the smartphone mounting member 51 side with the hook-and-loop fastener 54, so the sheet 52 does not stick to or detach, making it easy to handle.

[0037] Figure 8 shows another embodiment, an example of a state in which multiple sheets 52 are attached. The upper and lower members 2c are positioned across the boundary line between two sheets 52 to realize a V-fold structure. In this case, there is the advantage that the enclosure member 2 does not interfere with the inner surfaces 50a and 50b of the main part 50. Its usage is the same as in the example above.

[0038] Figure 9 shows another embodiment, in which the enclosure member 2 is attached to the inner surface 50a of the main part 50 on the left side, with the sheet 52 rotatably mounted perpendicular to the opening direction of the case 1'. In this case as well, the enclosure member 2 can be automatically opened by opening the sheet 52 vertically using the V-fold structure.

[0039] Figure 10 shows another embodiment in which the enclosure member 2 is attached only to the surface of the sheet 52, and the surface of the sheet 52 to which it is attached is the surface 52a of the left and right main parts 50 of the case 1' that does not face the inner surface 50b on which the smartphone is mounted. This makes it less likely for the smartphone to be interfered with by the enclosure member 2. In this embodiment, the enclosure member 2 does not stand up just by opening the sheet 52, so as will be explained in the embodiments related to the present invention described later, the enclosure member 2 is opened and raised with a finger.

[0040] Alternatively, as shown in Figure 10, the enclosure member 2' may be attached only to the inner surface 50a of the main part 50 on the left side. The sheet 52 will serve as a cover.

[0041] In the above embodiment, the air intake section 8, as described later, is provided in the portion of the main section 50 enclosed by the enclosure member 2. Alternatively, it may be provided on the enclosure member 2 itself. Alternatively, the air intake portion 8 may be located within the enclosed portion 2 of the sheet 52 itself. Even when the sheet 52 is opened and fastened with the hook-and-loop fastener 54, the height of the hook-and-loop fastener 54 creates a gap between the sheet 52 and the smartphone mounting component 51, resulting in an air layer. Therefore, even if the air intake portion 8 is located in the sheet 52 itself, air can be taken in and out.

[0042] Alternatively, the air intake section 8 may be provided in all of the main section 50, the enclosure member 2, and the sheet 52, or in any two of them.

[0043] Such an air intake unit 8 has a filter layer or filter member that can filter out smoke and toxic gases. The structure of this air intake unit 8 and the filter layer and filter member provided therein can be modified using the technologies of the related inventions described later.

[0044] Figure 11 shows another embodiment of the present invention. The difference from the embodiment in Figure 3 is that the opening direction of the upper and lower members 200c of the enclosure member 200 is reversed.

[0045] Here, Figure 12 is a planar view of one of the upper and lower members 200c. Figure 13 shows the left and right members 200d, 200d. Figure 14 is a diagram that depicts the overlapping when closed, with a slight shift in some parts to make it easier to understand.

[0046] 200c2 is the left end of the upper upper / lower member 200c, and 200c3 is the lower end of the upper upper / lower member 200c. 200c1 is the overlap portion.

[0047] 200d1 is the upper end of the left member 200d (upper side in Figure 11) and is joined to the left end 200c2 of the upper upper / lower member 200c. 200d3 is the fold line on the upper side of the left member 200d (upper side in Figure 11). Closing along this fold line makes it easier to fold.

[0048] 200d2 is the central curve line of the left member 200d, and it is curved. 200d4 is the folding line in the central part of the left member 200d. When closed, it becomes easier to fold.

[0049] 200d5 is the lower end of the left member 200d and is fixed to the inner surface 50a of the left main part 50, but it is desirable that its lower end 200d5 is fixed to the inner surface 50a of the main part 50 so as to be perpendicular to the lower end 200c3 of the upper upper and lower members 200c.

[0050] As shown in Figure 12, the lower end 200c3 of the upper and lower member 200c forms, for example, a 70-degree angle with respect to the center line M that is folded. When installed, it is set to 65 degrees.

[0051] Figure 15 shows a modified example of the upper and lower member 200c, which has upper and lower members 200c'. Here, 200c'-a is the upper end corner of the upper and lower member 200c', and it protrudes to the left and right. In other words, if a virtual line Z is drawn parallel to the center line M of the fold from the outer corner 200c3k of the lower end 200c3 of the upper upper and lower member 200c', the upper end corner 200c'a protrudes outward from that virtual line Z. As a result, when opened and stood upright, the enclosure member 2 tends to open outward, making it easier to put your face against it.

[0052] Furthermore, in order to prevent wrinkles or excessive force from forming in such shapes and arrangements, it is desirable to use materials with flexible elasticity.

[0053] Figure 16 is an explanatory diagram of the case 1' and a filter layer or filter component built into it, which can filter smoke and toxic gases, for the aforementioned notebook-type smartphone. Although the enclosure component 2 is omitted, its material is made of an airtight, non-permeable material. 52 is the sheet mentioned above.

[0054] In this example, case 1' is a bag-shaped box case, with the left side 1'L and the right side 1'R consisting of somewhat elastic but rigid walls, and the central part 1'C consisting of a flexible wall. Therefore, it can be folded. Furthermore, the material of the box-shaped case is made of an airtight, non-permeable material, except for the parts where the pores described below are formed.

[0055] The left side 1'L and the right side 1'R each house a filter layer / filter member 60L and 60R, respectively. The left filter layer / filter member 60L is in close contact with the inner surface 50a of the main left part 50 of the case 1' on the inner surface of the case 1' (the upper side in Figure 16, which becomes the inner side when folded) (see Figure 18).

[0056] Furthermore, in the inner surface 50a of the main part 50 on the left side of case 1', a large number of permeable pores are formed in all or part of the area 64 surrounded by the enclosure member 2 (reference numeral 64 in Figure 17 indicates the enclosed area of ​​the enclosure member 2) and in which the filter layer / filter member 60L is in close contact (see 61 in Figure 17). Even within the area 64 surrounded by the enclosure member 2, the parts where the filter layer / filter member 60L is not in close contact are sealed in a non-permeable state.

[0057] On the other hand, at least a portion of the wall of case 1' that is not enclosed by the enclosure member 2 has numerous pores that allow for ventilation. Preferably, these are formed on the outside of case 1' (the lower side in Figure 16, which is the side that becomes the outside when folded).

[0058] Furthermore, preferably, as shown in Figure 18, a number of pores 62 are formed on the outside of the main part 50 on the right side of case 1', and the right-side filter layer / filter member 60R is tightly fitted to the formed portion, so that the air passing through the pores 62 always passes through the filter layer / filter member 60R.

[0059] Furthermore, since two filter layers / filter components 60L and 60R are built into a single bag-shaped box case 1', even if the central part 1'C is somewhat narrowed, air is still in communication between the two.

[0060] Furthermore, the left-side filter layer / filter member 60L may be in close contact with the outer surface 63 of the left-side main part 50 of case 1', as shown in Figure 18, and may also have pores formed there.

[0061] Furthermore, in the case 1' wall, if the filter layer / filter member 60 is in close contact with either the pores within the area 64 enclosed by the enclosure member 2 or the pores in the area not enclosed by the enclosure member 2, a minimum level of filtering function can be achieved.

[0062] Furthermore, as a variation, aluminum foil may be attached to cover the areas where the aforementioned pores exist. This prevents deterioration of the filter layer and filter components 60L and 60R. Of course, it is necessary to attach it in a way that it can be peeled off by hand if necessary.

[0063] Figure 19 is a perspective view of a foldable notebook-type smartphone case in an embodiment of the invention related to the present invention, and Figure 20 is a perspective view showing the enclosure member of the notebook-type smartphone case in an upright position. Part of this technology is applied to each of the embodiments of the present invention described above.

[0064] In Figure 19, 1 is the main body of the smartphone case, 2 is the enclosed member in a folded state, 3 is the main surface of the main body 1 of the smartphone case, 4 is the base piece for attaching the smartphone 10 to the main body 1 of the smartphone case, 5 is the connecting piece when the notebook-type smartphone case is closed, 6 is the hook-and-loop fastener for joining the enclosed member 2 to the main surface 3 of the main body 1 of the smartphone case in a lying position, and 7 is the hook-and-loop fastener for joining the enclosed member 2 when it is folded. The enclosed member 2 is part of the face rest portion F of the present invention. That is, the face rest portion F in this embodiment is composed of a broad part of the main body 1 of the smartphone case and the enclosed member 2.

[0065] Here, Figure 19 shows the enclosure member 2 in a folded and laid-down state. The enclosure member 2 consists of an enclosure member 2a located at the top and bottom and an enclosure member 2b located on the left and right. The adjacent enclosure members 2a and 2b are folded at both ends as described later and are in close contact with the main surface 3 of the smartphone case body 1, and this contact is maintained by a hook-and-loop fastener 6. The enclosure members 2a and 2b are also in close contact with each other, and this contact is maintained by a hook-and-loop fastener 7.

[0066] Furthermore, although omitted in Figure 19, as shown in Figure 20, an air intake section 8 is provided on the main surface 3 of the smartphone case body 1. As shown in Figure 21, this air intake section 8 mainly consists of a protective surface layer 8a and a filter layer 8b, in that order from the outside. Note that this main surface 3 is almost the same as the main part 50 described above.

[0067] This filter layer 8b is a layer that has the function of filtering toxic gases such as carbon monoxide, soot, hydrogen chloride, and hydrogen sulfide. The protective surface layer 8a is the outer layer that protects the filter layer 8b and has many holes that allow air to take in. As described above, the enclosure member 2 is fully or partially bonded to this filter layer 8b when it is lying down. This enclosure member 2 is usually made of a material that does not allow air to pass through, but it can also be made to allow air to pass through when the function of the filter layer is to be performed.

[0068] Next, we will explain how to fold the enclosure member 2. Figure 22 shows one example of how to fold it. Figure 22(A) shows how to fold it so that the end 2a1 of the upper enclosure member 2a is on the bottom and the end 2b1 of the left enclosure member 2b is on the top (see the hollow arrow). Figure 22(B) shows the result. Note that this is not the only way to fold it; any folding method is acceptable.

[0069] Next, we will explain what to do in the event of a fire. First, open the main body 1 of the smartphone case to the left and right, and then remove the smartphone 10. After that, with the enclosure member 2 lying flat as shown in Figure 19, hook your finger at the location indicated by the hollow arrow and peel off the hook fasteners 6 and 7, and raise it to a fully upright position as shown in Figure 20. With the main body 1 of the smartphone case open and the enclosure member 2 fully upright in all directions, hold the front side with your palm as shown in Figure 23, and press the enclosure member 2 against your face so that it covers your nose and mouth. Figure 23(A) is a perspective view showing this, and Figure 23(B) is a schematic cross-sectional view showing this.

[0070] This method allows for emergency evacuation by filtering out toxic gases generated by the fire while breathing.

[0071] As shown in Figure 24, it is desirable to have a surrounding member 2 that fits the face of people of all ages and genders as much as possible. Therefore, it is desirable to first determine the shapes of various surrounding members 2 that can accommodate people of all ages and genders, attach them to the main body 1 of the smartphone case, and make them foldable. To achieve this, it is not always necessary to raise the surrounding member 2 from the outer edge of the main body 1 of the smartphone case. By doing so, it is possible to eliminate the gap between the face and the case. In other words, although the shape of the main body 1 of a smartphone case is usually rectangular, the shape of the surrounding member 2 is not limited to a rectangle.

[0072] Figures 25 to 30 show detailed specific examples of the air intake section 8.

[0073] <Specific example> This method involves creating a window 25 in the main surface 3 of the smartphone case body 1 (see Figure 28), and then fitting the assembled components into it as follows.

[0074] As shown in Figure 25, a filter member 21 having at least a filter layer is bonded to a rigid, sturdy perforated plate 20. This is then fitted into an aluminum frame 22. Figure 26(A) is a perspective view of the fitted state, and Figure 26(B) is a cross-sectional side view thereof. Figure 26(C) shows an example in which a spacer 23 is interposed between the perforated plate 20 and the filter member 21, in order to prevent the filter member 21 and the perforated plate 20 from being too tightly fitted together and thus reducing the filtering function.

[0075] Figure 27(A) is a perspective view showing the aluminum foil 24 attached to the front and back sides of the fitted component, and Figure 27(B) is a cross-sectional view thereof. The aluminum foil 24 is adhered to the aluminum frame 22, so it has high sealing properties.

[0076] Figure 28 shows how the aluminum foil 24 is bonded and the filter member 21 is sealed, and how this member is fitted into the main body 1 of a smartphone case, which has a window 25 cut into its main surface 3. It is necessary to firmly bond and secure it when fitting it in, because it should not wobble when the aluminum foil 24 is peeled off later. 26 is a spacer member, which prevents the main surface 3 from strongly contacting the filter member 21 when the main body 1 of the smartphone case is folded when the smartphone is not in use.

[0077] Thus, the filter layer or filter member 21 of the air intake section 8 is sealed using a sealing member composed of a metal plate, frame, or foil. The same applies to the following embodiments.

[0078] Figure 29 is an inside perspective view after the decorative sheet 27 has been applied on top, and Figure 30 is an outside perspective view.

[0079] In the embodiments and specific examples described above, in an emergency, the smartphone 10 can be removed, the enclosure member 2 can be raised, or the sheet 52 can be opened to cause the enclosure member 2 to automatically rise, and by peeling off the aluminum foil on the front and back, a smoke / gas mask can be immediately completed, making it easy to use even in a panic. In addition, since the filter member 21 is sealed with aluminum material, it can maintain its effectiveness for a long period of time.

[0080] Furthermore, the assembly sequence described in the above-mentioned specific example is not necessarily the same as the actual manufacturing sequence when producing the smartphone case of the present invention. Some parts of the explanation are deliberately presented in a sequential manner to make the structure easier to understand. Therefore, the manufacturing sequence and method are not limited to those described herein and can be any method.

[0081] As mentioned above, the enclosure member of the present invention does not necessarily have to be provided on the outer circumference of the smartphone case body. For example, it may be erected from the middle of the inner surface of the smartphone case body. Alternatively, a part of the enclosure member, for example, the upper part, may be provided on the outer circumference, and the remaining lower part may be erected from the middle of the inner surface of the smartphone case body.

[0082] Furthermore, the air intake section 8 is not necessarily required. In other words, by increasing the height of the enclosure, the enclosed space can be enlarged, and in such cases, for short distances of 10m or 20m, evacuation may be possible using only the air within that large space. This is because oxygen remains in the exhaled air. In any case, the goal is to prevent inhalation of carbon monoxide and other pollutants generated at the scene of a fire.

[0083] Furthermore, as described above, a part of the enclosure member of the present invention may be provided with an air intake section having a filter layer or filter member capable of filtering smoke and toxic gases. Alternatively, air intake sections having a filter layer or filter member may be provided on both the main body side of the smartphone case and the enclosure member side. The filter layer or filter member may, for example, consist of multiple layers of adsorption layers or catalyst layers.

[0084] Furthermore, it is possible for a person escaping a fire to peel off a pre-sealed aluminum bag containing the filtering material and then fit and attach it to the main body of a smartphone case with an enclosure and window, as in the above example. In such a case, care must be taken to avoid creating any gaps between the filter material and the main body of the smart case.

[0085] Furthermore, in this invention, the material is not limited to aluminum foil, aluminum plate, aluminum frame, etc., but other metals may also be used, and even if the sealing performance is slightly weaker, resin materials may be used instead.

[0086] Furthermore, the present invention is not limited to a type that opens and folds to the left and right, but may also be a type of notebook-style smartphone case that opens and folds to the top and bottom. This is because the straight part that folds when used in a fire can be aligned with the nose. [Industrial applicability]

[0087] The smartphone case of the present invention can be used as a smartphone case in everyday life, and because it is readily available in the event of a fire, it can be immediately used as a smoke or gas mask, making it useful as a smoke or gas mask during a fire. [Explanation of Symbols]
