As used herein, the meaning of'comprising' embodies certain properties, regions, integers, steps, actions, elements and/or components, and other specific properties, regions, integers, steps, actions, elements, components and/or groups It does not exclude the existence or addition of.

Hereinafter, a bag having a buffer function according to an embodiment of the present invention (hereinafter, a bag having this buffer function is referred to as a'bag') will be described with reference to the accompanying drawings.

1 to 3, the bag 10 of this example includes an outer bag portion 100 and an inner bag portion 200.

The outer bag portion 100 includes a receiving space (first receiving space) R11 in which the inner bag portion 200 is built.

The outer bag part 100 includes a lower part (not shown), a side part 120 connected to the lower part, an upper part 130 connected to the side part 120, and a moving part 140 attached to the side part 120. ).

The lower part is a part that forms the bottom of the outer bag part 100, has various planar shapes such as a square or a circle, and a reinforcing plate (not shown) for supporting the weight of the bag 10 is built in. Can. At this time, the reinforcing plate may be made of plastic or the like.

The side part 120 forms the body of the outer bag part 100.

The side 120 is shaped according to the planar shape of the lower portion connected to itself, and when the lower portion has a rectangular planar shape, the side portion 120 has a rectangular pillar shape having a receiving space R11 in the middle. You have.

The lower edge portion of the side portion 120 is connected to the edge portion of the lower portion 110 through a sewing operation or the like.

Due to this, the empty space formed by being surrounded by the lower part 110 and the side part 120 becomes a receiving space R11 in which the inner bag part 200 is embedded.

However, in an alternative example, the outer bag portion 100 may have at least one additional receiving space in addition to the receiving space R11 using a separate partition.

The upper part 130 is connected to the side part 120, and an incision part OP11 is positioned on a part, so that at least a part of the upper part 130 functions as a cover that can be opened and closed.

A zipper is located in the incision part OP11 of this example to control the opening and closing operation of the cover, but the present invention is not limited thereto, and the incision part OP11 is opened or closed by using another locking means such as a velcro. To make it happen.

Due to this, when the incision OP11 located in the upper part 130 is closed, the upper part of the receiving space R11 is closed by the upper part 130, and the contents located in the receiving space R11 are drained outward. It does not come out and is safely located in the receiving space R11.

The planar shape of the upper 130 is determined according to the planar shape of the side portion 120 connected to it, and in this case, since the side portion 120 has a rectangular planar shape, the upper portion 130 may also have a rectangular planar shape. have.

The moving part 140 is for moving the bag 10, and consists of two belts attached to the corresponding part of the side part 120. Accordingly, the user can move the bag 10 on the shoulder using these belts 140.

The belt 140 may be connected to the corresponding portion of the outer bag portion 100 in a detachable structure.

However, unlike in the present example, in an alternative example, in addition to the mobile unit 140 that can be worn on the user's shoulder, a handle that allows the user to lift the bag 10 by hand may be mounted on the upper portion 130 or moved. Instead of the portion 140, only the handle can be mounted to the upper middle portion.

In addition, at least one of the side portion 120 and the upper portion 130 of the outer bag portion 100 is provided with one or more incision portions OP12 that can be opened and closed using a locking means such as a zipper or velcro. However, in an alternative example, the locking means may not be located in the incision OP12.

Therefore, the user does not open the cover located on the upper 130 and opens and closes the incision OP12 located at the corresponding portion of the upper 130 or the

sides

120 and 130 to take out the contents located in the bag 10 or the bag (10) The contents are stored inside.

The inner bag portion 200 is provided with a receiving space (second receiving space) R21 therein, as shown in FIG. 4, and inserted into the receiving space R11 of the outer bag portion 100 as required by the user. It can be positioned or removed outside the accommodation space (R11) and used as a separate bag.

5, the inner bag portion 200, as shown in Figure 5, the outer shell 210, the cushion portion 220, the protection portion 230, the inner shell 240, located on the cushion portion 220, And it is provided with a moving unit 250.

The outer shell 210 is a portion forming the outermost side of the inner bag portion 200 and is an outer portion of the inner bag portion 200.

The cushion part 220 includes two

sheets

2201 and 2202 facing each other in opposite directions as shown in FIG. 5, and air is injected between the two

sheets

2201 and 2202 or the injected air is discharged to the outside. do. Therefore, when air is injected between the two

seats

2201 and 2202, an air cushion portion is provided to provide an air layer between the two

seats

2201 and 2202 to reduce shock applied from the outside.

The cushion portion 220 has a shape determined according to the shape of the inner bag portion 200.

Referring to the developed view shown in FIG. 6, the cushion portion 220 includes a main body 221, a connection portion 222, and a valve insertion portion 223 having a valve insertion hole 2231.

When the inner bag part 200 is used as a separate bag, the main body 221 is a part capable of injecting air between the two

sheets

2201 and 2202 because the two

sheets

2201 and 2202 are not joined and separated. , It has a lower surface (S221) forming the bottom and a side (S222) forming the side.

To this end, of the edge portions of the body 221, the two

seats

2201, 2202 located at all edge portions except the valve insertion hole 2221 are joined to each other and are surrounded by the body portion 221 surrounded by the joined edge portions. The two

sheets

2201 and 2202 are separated without being joined.

Therefore, the main body 221 forms one air bag in which only the valve opening 2223 is opened.

The connecting portion 222 is located in the middle portion of the cushion portion 220 surrounded by the edge portion of the main body 221, the number of which is one or more.

Each of these connecting portions 222 is a region formed by bonding two

sheets

2201 and 2202 positioned in a portion that completely encloses a defined region, and is a region in which air injection is not performed.

Therefore, the

sheets

2201 and 2202 located at the edge portion of each connecting portion 222 are joined to each other.

Due to this, the two sheets are completely joined at the edge portion of the connecting portion 222, but the two

sheets

2201 and 2202 located at the portion surrounded by the edge portion are not joined but are separated from each other.

The connection portion 222 is connected to the corresponding portions of the outer shell 210, the protective portion 230, and the inner shell 240 of the cushion portion 220 through a sewing operation or the like, thereby fixing the position of the cushion portion 220 .

As already described, the periphery of the connection portion 222 is completely blocked and thus blocked from the main body 221 through which air is injected, and thus a hole such as a needle hole in the connection portion 222 due to a sewing operation for fixing the position of the cushion portion 220 Even when this occurs, the air of the body 221 is not discharged through the hole formed in the connection portion 222.

The connection part 222 may be mainly located between a portion where a folding operation is performed to form a desired shape of the cushion part 220, for example, between the lower surface S221 and the side surface S222 of the cushion part 220. .

Therefore, when air is injected into the main body 221, since the air is not injected into the connecting portion 222, the assembling operation of the inner bag portion 200 is easily performed.

In addition, the air injection into the cushion 220 is more uniformly made and the air injection becomes easier as the connection portion 222 where air injection is not performed is located in the middle of the cushion portion 220.

The valve inserting portion 223 is a portion into which an air injection valve 300 (eg, a first valve), such as a check valve, is inserted, and is a portion protruding from the main body 221 to the outside.

In addition, the valve insertion portion 223 is provided with a valve 400 for discharging air for discharging the air in the cushion portion 220 to the outside as well as the valve 300 for injecting air. The valve insertion portion 223 has a portion where the two

seats

2201 and 2202 are separated from each other because the two

seats

2201 and 2202 are not joined at the edge portion of the body 221, as already described. Forms a valve insertion hole 2231.

The valve inlet 2223 is provided with a valve 300 for air injection and a valve 400 for air discharge (eg, a second valve), so that the outer surfaces of the corresponding

valves

300 and 400 and the two seats contacting the outer surfaces ( The parts of 2201, 2202) are joined to each other.

By this bonding, air injection into the body 221 is made only through the inlet 320 formed in the valve 300 for air injection, and air discharge from the inside of the body 221 to the outside is the valve 400 for air discharge It is done through.

As such, in the case of this example, the valve insertion portion 223 protruding outward from the main body 221 is provided for valve insertion, but unlike this, the valve insertion portion 223 may be omitted. In this case, the valve insertion holes for the two

valves

300 and 400 are portions where the two

seats

2201 and 2202 are not adhered to each other at the edge portion of the body 221, but are partially open.

6, the body 221 of the cushion part 220, that is, at least one of the bottom surface S221 and the side surface S222, the two

seats

2201, 2202 are bonded to each other so that air injection is not performed The plurality of joints 224 are dispersed and located.

At this time, the area of each junction 224 is made of a point shape or various other shapes, and has a size smaller than that of each connection 222, and the distance between two adjacent junctions 224 may be constant or irregular.

The joining portion 224 is also a portion in which two

sheets

2201 and 2202 are joined to each other, and is a portion in which air injection is not performed.

Therefore, when air is injected through the valve 300 for air injection, the surface of the main body 221 has an uneven structure, so that the distribution of air injected into the main body 221 is more uniform.

However, the junction 224 may be omitted if necessary.

In addition, as shown in FIG. 6, in the case of the present example, among all sides of the lower surface S221, there may be a side where the side surface S22 is not connected, so that the main body 221 has an open portion that does not have a side surface. It is provided, and is located on the opposite side of the lower surface (S221), the upper surface, which is the surface facing the lower surface (S221) does not exist, so the surface facing the lower surface (S221) of the main body (221) is open.

For this reason, when the inner bag portion 200 is located in the accommodation space R11 of the outer bag portion 100, a portion where the cushion portion 220 is unnecessary, for example, the inner bag portion 200 is the outer bag portion When inserted into the accommodation space (R11) of (100), the cushion portion 220 is not present in a portion positioned to correspond to the bottom of the outer bag portion 100, thereby reducing the amount of material consumed.

In addition, when the inner bag portion 200 is located in the accommodation space R11 of the outer bag portion 100, a portion corresponding to a portion where the cover or incision OP1 of the outer bag portion 100 is located (eg, Since the cushion portion 220 is also not located in the upper surface of the inner bag portion 200), when the cover or incision OP12 of the outer bag portion 100 is opened, the receiving space of the inner bag portion 200 ( R21) leads directly to the outside. Due to this, the contents located in the accommodation space R21 of the inner bag portion 200 are easily taken out or stored by the user.

However, unlike in this example, in the alternative example, when manufacturing the inner bag portion 200, the cushion portion 220 is not located so that there is no portion, the inner bag portion 200 on all sides It can be manufactured so that the cushion portion 220 may exist.

The air injection valve 300 is connected to the main body 221 so as to be in communication with the inside of the main body 221, and a small air pump used in a dust removal pump or toy used as one of the photographing equipment, such as an air pump made of rubber. An air pump, such as, is connected to inject air into the body 221.

The blocking film 310 for preventing air injected into the main body 221 from being discharged to the outside is located in the valve 300 for air injection.

Accordingly, when an air pump having an air outlet for air discharge is inserted into the inlet 320 of the air injection valve 300, the air outlet inserted into the air injection valve 300 pushes the blocking film 310. The blocking film 310 is opened by the pushing force. Due to this, the air outlet passes through the blocking film 310 so that air is injected into the main body 221.

However, when the air outlet is removed from the blocking film 310, the position of the blocking film 310 is restored to the initial position by the restoring force of the blocking film 310 to maintain the closed state, which is the initial state. Due to this, the air located in the main body 221 is not discharged to the outside.

The air discharge valve 400 is also connected to the main body 221 to be in communication with the inside of the main body 221, for example, the exhaust port of the valve 400 by a force applied from the outside in an initial state in which the exhaust port 410 is blocked 410 has a structure that is automatically opened. At this time, when the applied force is removed, the state of the exhaust port 410 of the valve 400 for air discharge is automatically switched to the closed state by the restoring force using a spring or the like.

By the air discharge valve 400, the user can discharge the air inside the main body 221 to the outside at a desired amount at a desired time.

In addition, the cushion unit 220 is further provided with a pressure gage 500 that is connected to the main body 221 in communication with the interior of the main body 221. At this time, the pressure gauge 500 is also located in the valve insertion portion 223 or is located to be connected to the interior of the body 221 in another portion of the cushion portion 220.

For this reason, the air pressure in the main body 221 is displayed outside to inform the user of the air pressure inside the main body 221. Therefore, the user can control the amount of air injected into the main body 221 using the size of the air pressure output through the pressure gauge 500, so that the body 221 does not have excessive force due to air pressure. .

However, the present invention is not limited thereto, and the pressure gauge 500 may be omitted if necessary. In addition, the pressure gauge 500 may be combined with the valve 300 or the valve 400.

The cushion portion 220 is manufactured using two

seats

2201 and 2202 as described above, and the shapes of the two

seats

2201 and 2202 are the same.

Accordingly, two

sheets

2201, 2202 having the same shape are positioned to face each other, and then two sheets located at the edge portion of the region where the corresponding edge portion and the connection portion 222 of the main body 221 are located using high frequency ( 2201, 2202). Accordingly, two

sheets

2201 and 2202 are joined to the edge portion of the body 221 and the edge portion that completely surrounds each connection portion 222, thereby joining portions L1 and L2 sealing the body 221 and the connection portion 222, respectively. ) Is formed.

At this time, the joining operation of the edge portion of the main body 221 and the joining operation of the edge portion of the connecting portion 222 may be performed simultaneously or separately.

Then, the two

valves

2201 and 2202 are not joined to each other and the corresponding

valves

300 and 400 are inserted into the valve insertion hole 2231 formed in the valve insertion portion 223 which is an edge portion of the body 221 that is open. do. At this time, even when the pressure gauge 500 is present, in order to mount the pressure gauge 500, two

edges

2202 and 2202 are not joined to the edge portion of the main body 221, and an open portion is also present. The pressure gauge 500 is inserted into the opened portion to perform the following operation. When the

valves

300 and 400 are inserted into the valve insertion port 2231, the corresponding valves inserted by irradiating high frequencies to the outer surfaces of the

valves

300 and 400 and the two

seats

2201 and 2202 contacting the outer surfaces ( The

seats

2201 and 2202 contacting the outer surfaces of 300 and 400 are bonded to the outer surfaces of the corresponding

valves

300 and 400.

For this reason, the valve insertion port 2231 is blocked by the

valves

300 and 400, and input/output of air to the main body 221 is possible only through the injection port of the valve 300.

In the joining operation between the inserted

valves

300 and 400 and the corresponding

seats

2201 and 2202, a high frequency joining operation is performed using a molding frame having a shape determined according to the outer shape of each

valve

300 or 400. That is, after positioning the main body 221 in which the

valves

300 and 400 are inserted in the forming frame, a high-frequency irradiation is performed to join the outer surfaces of the

respective valves

300 and 400 and the corresponding seat. Due to this, the

valves

300 and 400 and the seat are joined without gaps, thereby preventing air in the body 221 from flowing out.

In the case of this example, since the valve insertion portion 223 protruding from the main body 221 is present, the high-frequency bonding operation is performed after the protruding valve insertion portion 223 is placed in the forming frame, so that the valve attachment operation is more easily It is done quickly and the occurrence of defective rate is reduced.

When joining the outer surfaces of the

respective valves

300 and 400 and the corresponding

seats

2201 and 2202, the

valves

300 and 400 are centered around the corresponding

valves

300 and 400 so that no unbonded portion occurs. The junction portion (L1) portion of the body 221 located at the upper and lower portions of the body (221) to be overlapped with the high-frequency irradiated portion (A1) for bonding with the valve (300, 400) (see Fig. 6).

Therefore, as shown in FIG. 7, the body 221, more specifically, the junction portion L1 formed at the edge of the body 221 to seal the body 221 and each

valve

300, 400 combined with the body 221 As the airtightness is secured by overlapping junctions L3 formed on the outer surfaces of the

valves

300 and 400, the inlet 320 or the exhaust port 410 of the

valves

300 and 400 are excluded from the cushion 220 And make sure that no air in and out occurs.

Through this process, as the cushioning part 220 of this example is manufactured, the manufacturing process of the cushioning part 220 is simplified and productivity is improved.

Meanwhile, in FIG. 7, the valve 300, the valve 400, and the pressure gauge 500 are shown separately, but at least one of them may be formed by being coupled to each other.

Next, an existing case of manufacturing an air bag having an air inlet such as a valve will be described.

In the conventional case, since only one of the two sheets is equipped with an air inlet, first, a work of drilling a portion to which the air inlet is to be attached to one sheet is performed, and the air inlet is bonded at a high frequency according to the position. When overlapping the sheet having the air inlet and the sheet not having the air inlet, the positions of the two sheets (lower or upper) are separated and positioned.

By separating the positions and positioning the corresponding sheets, the edges of the two sheets overlapping each other are completely joined through a high-frequency bonding process.

As described above, since there is a sheet on which an insertion hole is formed and a sheet on which an insertion hole is not, an operation of separating and positioning two sheets in a manufacturing process is required, and a process of forming a separate insertion hole on the corresponding sheet should be added.

However, in the case of this example, since the two

seats

2201 and 2202 having the same shape are mounted by inserting a valve in a part of an open portion of the edge portion in contact with each other, it is necessary to distinguish the

seats

2201 and 2202 for valve insertion. There is no need for a process for forming an insertion port for valve insertion in either seat.

In addition, the joining process of the edge portion where the valve is inserted is made easier than the existing process, which is the joining process of the air inlet located in the corresponding seat, and the occurrence of defective rate is less.

For this reason, in the case of this example, productivity is improved and the defect rate of the product is reduced compared to the existing case.

In this example, the material of the two

seats

2201 and 2202 constituting the cushion portion 220 is made of a material having elasticity such as polyurethane (PU, polyurethane), PVC (poly vinyl chloride) or rubber, and aging resistance. Better is better.

In addition, the endurance pressure of each

sheet

2201 and 2202 is preferably larger than the maximum air injection pressure of the air pump, and may be, for example, 200 mmHg to 600 mmHg, whereby each

sheet

2201 and 2202 has a specified endurance pressure. It is good to have a thickness that satisfies the conditions. As an example, the thickness of each

sheet

2201 and 2202 may be 0.2 mm to 0.5 mm.

In this example, the thickness of each

seat

2201 and 2202 is referred to as the thickness of the cushion portion 220.

Body 221, that is, the endurance pressure of the cushion 220 is greater than the maximum air injection pressure of the air pump as a result, as shown in Figure 9, the air injected through the air pump to the maximum air injection pressure (P12) the body (221) Even if it continues to flow inside, it becomes smaller than the endurance pressure (P11) of the body 221, so that the body 221 stably withstands air pressure, thereby preventing damage to the body 221 due to air pressure of the air pump. .

When the cushion portion 220 of this example is made of polyurethane, the impact resistance is better than that of PVC. Therefore, the contact defect rate generated during high frequency contact is reduced, and the risk of damage due to external impact is also reduced.

In addition, since the endurance pressure of polyurethane is better than that of PVC, when the main body 221 is made of polyurethane, the risk of damage due to the air pressure of the main body 221 is also reduced compared to the case of PVC.

In addition, since portions of the

valves

300 and 400 that are adhered to the corresponding

seats

2201 and 2202 are also made of polyurethane, an increase in adhesion between the two seats and the

valves

300 and 400 is increased during a high-frequency bonding process, thereby reducing the defect generation rate. .

The protection unit 230 is positioned to correspond to the cushion unit 220 on the cushion unit 220, and the receiving material in the receiving space R21 formed in the cushion unit 220 and the cushion unit 220 located at a lower portion from external impact. Protect.

In this example, the protective part 230 is a foam sheet part made of a high-density baldoxite such as EVA (ethylene vinyl acetate copolymer).

Due to the protection unit 230, it is possible to prevent a hole in the cushion unit 220 or damage to the cushion unit 220 by contents such as photographing equipment located in the receiving space R21 of the inner bag unit 200 do.

In addition, the protection unit 230 acts as a support portion for fixing the shape of the inner bag portion 200, so that the shape of the inner bag portion 200 maintains a desired shape.

As described above, since the protection part 230 is located on the cushion part 220 located at the bottom thereof, it has a shape similar to the cushion part 220 located at the bottom and additionally has an upper surface.

Therefore, as shown in FIG. 8, the developed view of the protection unit 230 is a surface (S231) forming a lower surface, a plurality of surfaces (S232) connected to the lower surface (S231) and forming a side surface, and a side surface ( S232) and has upper surfaces S2331 and S2332 positioned to correspond to the lower surfaces S231.

At this time, as shown in FIG. 8, the protection unit 230 also has a side to which the side surface S232 is not connected among the various sides of the lower surface S231, such as the cushion part 220, and the side surface S232 is not present. The position of the side which does not correspond to the position of the side of the cushion part 220.

That is, since one of the roles of the protection unit 230 is to protect the cushion unit 220 positioned below the protection unit 230, the protection unit 230 does not need to exist in the portion where the cushion unit 220 does not exist. For this reason, the manufacturing cost for manufacturing the protection unit 230 is reduced.

The upper surfaces S2331 and S2332 include first and second upper surfaces S2331 and S2332 that are connected to the upper edge of the same side, which is one of the plurality of sides S232, and are fixed to the side surfaces. The second upper surfaces S2331 and S2332 are separated from each other by the cutout OP21. Accordingly, an incision OP21 is positioned between the first upper surface S2331 and the second upper surface S2332 surrounded by the first upper surface S2331.

The protection unit 230 may be omitted if necessary, and in this case, the cushion unit 220 may be made of a material that is not easily damaged or damaged by external impact or physical force.

The endothelial 240 is a portion that forms the inner surface of the inner bag portion 200, the entire interior exposed to the outside of the inner bag portion 200, for example, the upper surface (S2331, S2332) of the protective portion 230 ).

However, not only the inner portion of the upper surfaces S2331 and S2332 of the protective portion 230 exposed to the outside, but also the outer portion of the lower surface of the cushion portion 220 exposed to the outside may be enclosed together.

The endothelial 240 may be made of a material having a waterproof and antifouling function.

The outer shell 210 is a part that forms the outer surface of the inner bag portion 200, and surrounds the entire outer portion of the inner bag portion 200, and is coupled to each other by an inner shell 240 and a sewing operation. Therefore, the portion where the cushion part 220 and the protection part 230 do not exist is also wrapped by the outer shell 210.

In addition, a locking means 260, such as a zipper or a velcro, is located in the portion of the outer shell 210 corresponding to the incision OP21 positioned between the first upper surface S2331 and the second upper surface S2332.

Therefore, when the locking operation is performed by the locking means 260, the first upper surface S2331 and the second upper surface S2332 are connected through the locking means 260.

However, when the locking means 260 is opened, the first upper surface S2331 and the second upper surface S2332 are separated from each other. At this time, the inner shell 240 and the outer shell 210 surrounding the first upper surface S2331 are connected to the inner shell 240 and the outer shell 210 surrounding the corresponding side surfaces of the adjacent cushion part 220 and the protective part 230. Are connected to each other.

Accordingly, the second upper surface S2332 of the protection unit 230 becomes a movable state based on the corresponding side surface S232 connected thereto, and functions as a cover capable of opening and closing the inner bag unit 200.

In addition, a portion of the protective portion 230, a portion of the inner shell 240 and a portion of the outer shell 210 corresponding to the connecting portion 222 of the cushion portion 220 are connected to each other by a sewing operation or the like, and each component is It is combined with each other to complete the inner bag portion 200.

In this example, the outer shell 210 and the inner shell 24 are a cover portion surrounding the cushion portion 220 and the protective portion 230, and the outer shell 210 and the inner shell 240 are collectively referred to as a cover portion. In this case, a lock means is positioned on the cover portion positioned to correspond to the incision portion OP21 between the first and second upper surfaces S2331 and S2332 to open and close the second upper surface S2332 which is a cover.

As already described, since the air connection is not made to the connection part 222 of the cushion part 220 and is completely physically blocked from the air injection made body 221, even if a needle hole or the like occurs in the connection part 222, the body 221 ), the operation of discharging the air injected is not performed.

In the present example, the inner skin 240 and the outer skin 210 are made of different materials, and the colors are different from each other, but the present invention is not limited thereto, and may be made of the same material and the colors may be the same.

In addition, a handle 250 is positioned on the inner bag portion 200 to facilitate the movement of the inner bag portion 200 to more easily position the inner bag portion 200 into the outer bag portion 300. Alternatively, the inner bag portion 200 located in the outer bag portion 300 can be easily removed.

In addition, when the inner bag portion 200 is removed from the outer bag portion 100 and used as a separate independent bag, the convenience of using the inner bag portion 200 is improved by using the handle 250.

When the inner bag portion 200 is inserted into the outer bag portion 100, as shown in FIG. 3, the position of the outer bag portion 100 may be changed without changing the position (that is, without a rotation operation) or in a desired direction. After changing the position by rotating to be inserted into the outer bag portion 100.

In the case of this example, the inner bag portion 200 is inserted into the receiving space R11 of the outer bag portion 100 after being rotated to the left in the normal position as shown in FIG. 4.

For example, the portion of the inner bag portion 200 in contact with the bottom surface of the outer bag portion 100 is such that the side portions of the cushion portion 220 and the protective portion 230 do not exist, and the cushion portion 220 ) In the open part (for example, the upper surface of the cushion part 220) is located in the outer bag part 100 where the incision parts OP11 and OP12 that can be opened and closed are located in the upper part 130 or the side part 120. Position them correspondingly.

Accordingly, as shown in FIG. 3, before putting the inner bag part 200 into the outer bag part 100, the user first opens the locking means 260 of the inner bag part 200 and then moves the cover S2332 toward the adjacent side. By moving, the cover S2332 is completely opened to expose the receiving space R21 of the inner bag part 200.

Then, by adjusting the position of the inner bag portion 200 so that the exposed receiving space R21 is positioned adjacent to the corresponding surfaces to which the incisions OP11 and OP12 are attached, the receiving space R11 of the outer bag portion 100 is adjusted. ).

For this reason, when the locking means mounted on the corresponding incision portions OP11 and OP12 of the outer bag portion 100 is opened, the receiving space R21 of the inner bag portion 200 is exposed to the outside, so that the user can press the inner bag. The contents existing in the accommodation space R21 of the portion 200 can be easily and quickly taken out or a desired object is placed in the accommodation space R21 of the inner bag portion 200.

In an alternative example, if there are side surfaces connected to both sides of the lower surface S221 of the cushion portion 220 and the lower surface S331 of the protection portion 230, the open portion of the cushion portion 220 In the outer bag portion 100, the upper portion 130 or the side portion 120 may be positioned to correspond to a portion in which incision portions OP11 and OP12 are opened and closed.
