SUMMARY OF THE INVENTION Therefore, an object of the present invention is to solve the above problems, and to provide a sterilization bag which has a simple structure and can be folded into a small size when not in use, and in which objects to be sterilized can be easily stored and taken out.

[0012]

To achieve the above object, the present invention provides a sterilization bag for accommodating an object to be sterilized such as a mattress or a tatami mat and sterilizing the object to be sterilized with ozone. A bag-shaped flow in which an ozone inlet and an ozone outlet are provided at one end of the body, and one end is connected to the ozone inlet and a plurality of ozone ejection holes are formed inside one surface of the bag. A passage is provided, and an opening / closing port is formed at the other edge while leaving one side edge of the bag body, and a fastener or a magic tape is provided at the opening / closing port.

In addition to the above structure, the present invention attaches the hook portion of the other velcro tape to one surface of the bag body and allows the hook portion to be detachably attached to the other surface of the bag body when the bag body is folded. The pile part of another velcro tape is attached so as to be joined.

In addition to the above construction, the present invention is one in which a spacer is inserted into the bag-like flow path of the bag body and a hole in the bag-like flow path is formed at the end.

[0015]

According to the above construction, when the sterilization bag is used, the fastener is opened or the Velcro is peeled off to open the opening / closing opening of the bag body, and the fastener is closed after the object to be sterilized is stored from the opening / closing opening, or The objects to be sterilized can be easily stored without sticking the objects to be sterilized by simply sticking the velcro tape. After sterilization, the object to be sterilized can be easily taken out only by opening the fastener or peeling off the velcro and opening the opening / closing port of the bag.

Since the bag-shaped flow path for introducing ozone into the bag body is formed integrally with the bag body, it is highly flexible, and the bag body can be folded together with the flow path when not in use. In the folded state, the bag body is stored in the folded state only by bringing the hook portion on one surface of the bag body into contact with the pile portion on the other surface.

By inserting a spacer into the bag-shaped channel of the bag and forming a hole in the bag-shaped channel at the end, when the object to be sterilized is stored in the bag, It is prevented that the flow path is blocked by the outside of the object and the object to be sterilized, and ozone is sufficiently distributed to the object to be sterilized.

[0018]

An embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a conceptual view of an embodiment of the sterilization bag of the present invention.

In the sterilization bag 31 shown in the figure, an ozone introduction port 33 and an ozone exhaust port 34 are provided at one end 32a of a substantially rectangular bag body 32. A substantially U-shaped sheet 36 having a plurality of ozone ejection holes 35 formed therein is attached to the inside of one surface of the bag body 32, and one end of the sheet 36 covers the ozone introduction port 33. There is. The sheet 36 and the bag body 32 integrally form a bag-shaped flow path 37.

A flexible tube 211 or the like as a spacer is inserted into the flow path 37, and the air outlet 35 is formed at a position where it is not blocked by the spacer.

The bag body 32 has a U-shaped opening / closing port 38 formed at the other end edge portion, leaving one side end edge portion 32a. Fasteners 39 are provided along the opening / closing port 38 so that the bag body 32 can be spread in a sheet shape with the one end edge portion 32a as the center.

A hook portion 40 of another velcro tape is attached to one surface (front side of the paper surface) of the bag body 32, and another velcro tape is attached to the other surface (back side of the paper surface) of the bag body 32. The pile portion 41 is attached. The hook portion 40 and the pile portion 41 are attached to a position where they are attached when the bag body 32 is folded (or rolled).

Next, the operation of the embodiment will be described.

For example, when sterilizing a mattress,
First, when the fastener 39 of the sterilization bag 31 is opened, the bag body 32 spreads like a sheet. By placing the mattress on the bag body 32 that spreads like a sheet and closing the fastener 39 after sandwiching the mattress with the bag body 32, the mattress can be easily formed without shaking the bag body 32 or pushing the mattress. It is accommodated in the bag body 32. After accommodating the mattress, the ozone introduction port 33 and the ozone exhaust port 34 are connected to the connection ports 10 and 11 of the sterilizer 1 by gas hoses 42 and 43. When the sterilizer 1 is operated, ozone gas passes through the gas hose 42 and the ozone inlet 33, and then passes through the flow path 3 of the bag 32.
Introduced in 7. Ozone is ejected from the ozone ejection hole 35 into the bag body 32.

In the spacer in the flow path, the bag-like flow path is folded or compressed between the mattress and the bag body, and the flow path from there is closed, and the ozone gas is blown out into the bag body. It is intended to prevent unevenness. Further, the position of the blowout hole 35 is also opened in such a positional relationship that it is not blocked by the spacer itself.

The mattress in the bag body 32 is sterilized and deodorized by the ozone blown from the blowout hole 35. After the time required for sterilization has passed, the control device stops the operation of the ozone generator 5 and operates the vacuum pump 7. The ozone in the bag body 32 is decomposed into oxygen by the ozone killer 6 of the sterilization apparatus 1 via the ozone exhaust port 34 and the gas hose 43, and then exhausted to the outside of the sterilization apparatus 1 from the exhaust port 9.

The control device stops the vacuum pump 7 after a lapse of the time required for exhausting ozone to complete the sterilization of the mattress.

After the sterilization is completed, by opening the fastener 39, the bag body 32 spreads like a sheet and the mattress can be easily taken out.

In this sterilization bag 31, the flow passage 37 is integrally formed inside the bag body 32. Therefore, when the sterilization bag 31 is not used, after folding the bag body 32 together with the flow passage 37, the velcro tape is used. The bag body 32 is stored in a folded state only by bringing the hook portion 40 of the above into contact with the pile portion 41.
Unlike the sterilization bag shown in FIG. 2, since the pipes 27 and 28 are not used, the flanges 23 and 24 are not required, and the number of parts is reduced accordingly.

As described above, according to the present embodiment, since the flow path for introducing ozone into the bag is formed in a bag shape, there is no rigid pipe, so that the structure is simple, and when not in use, it can be folded into a small size to be sterilized. No more getting caught in the pipe when storing or taking out. Further, since the sterilization bag is inexpensive, the entire bag body can be replaced when it is stored when it has a long life. Further, since the spacer is provided in the bag-shaped flow path, the mattress in the bag can be sufficiently spread with the ozone gas without being crushed.

FIG. 2 is a conceptual diagram of another embodiment of the sterilization bag of the present invention.

The difference from the embodiment shown in FIG. 1 is that a velcro tape is used at the opening / closing port instead of a fastener to seal the bag body.

The sterilization bag 310 shown in the figure has an opening / closing port at one end (left side in the figure). In order to maintain the airtightness of the bag 311, the bag 311 is arranged so as to be closed in a state where the end (opening / closing side) 311a of the bag 311 is bent a plurality of times (for example, a hook portion of a magic tape is provided on the surface of the bag 311). 21
2 is attached, and the pile portion 213 is attached to the back surface of the bag body 311 in parallel with the hook portion 212 at a constant interval).

When sterilizing the mattress, the bag 31
The mattress is stored from the opening / closing opening of No. 1 and the end portion 311a is bent, and the hook portion 212 of the velcro and the pile portion 2
13 is attached and hermetically sealed, and the ozone inlet 3
3 and the ozone exhaust port 34 are connected to the connection port 1 of the sterilizer 1, respectively.
When 0 and 11 are connected by gas hoses 42 and 43 and the sterilizer 1 is operated, ozone is introduced into the sterilization bag 20 and the mattress is sterilized and deodorized.

After the sterilization, the hook portion 2 of the Velcro tape
The mattress can be taken out by peeling 12 and the pile portion 213 and opening the bag 311.

In the above-mentioned embodiment, the bag-like flow path is formed in a substantially U-shape, but the present invention is not limited to this, and the V-shape, U-shape, T-shape, etc. Other shapes may be used. Further, in the figure, the number of hook portions and pile portions of the velcro tape is one each, but it is not limited to this.

[0038]

In summary, according to the present invention, the following excellent effects are exhibited.

Since a bag-shaped flow path for introducing ozone gas into the bag body is integrally formed in the bag body and a fastener or a magic tape is provided at the opening / closing port, the object to be sterilized can be stored with a simple structure. It is easy to take out and can be folded into a small size when not in use.
