Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a vacuum packing method for clothes, bedding, etc.,
In particular, the present invention relates to a method for storing a vacuum pack such as clothes or bedding for the purpose of reducing the storage location.

[Prior Art] Clothing or bedding is usually folded as it is and stored in a closet, a closet or the like. If they are applied with too much force, they may cause damage such as wrinkles, and they may be damaged by mold, moisture, insect worms, etc. over a long period of time, so relatively careful handling is required.

[Problems to be Solved by the Invention] Clothing and bedding have a very large volume as compared with the overlapping thereof, and due to the recent narrowing of the housing, the storage place of these at home or in the cleaning industry etc. Have a hard time. In addition, the large volume causes difficulties in handling and moving them. Furthermore, because it is necessary to use different clothing and bedding depending on the season, out-of-season clothing is usually stored for more than half a year, for example, so the problem of the storage location is only highlighted. In addition, there is concern about damage due to insects, moisture, mold, etc. during storage.

For this reason, conventionally, there has been a demand for a method of reducing the storage space for clothes or bedding in the home or cleaning industry, etc., and storing them without fear of damage due to insects, moisture, etc. It was rare.

In view of the above problems, an object of the present invention is to provide a storage and storage method for economically reducing the storage space of clothes or bedding and eliminating the risk of damage due to insects, moisture, mold, etc. It is to provide a simple handling method for transportation.

[Means and Actions for Solving the Problems] The object of the present invention is achieved by the following vacuum packing method for clothes or bedding and a vacuum bag storage bag.

Clothing or bedding is stored in the temporary bag 1 having the opening 2 and the exhaust port through the opening 2, and after sealing the opening 2, the air inside the temporary bag 1 is exhausted and decompressed through the exhaust port, A clothing or a bedding in which the entire temporary bag is housed in a storage bag 1 ′ having an opening 2 ′ and an exhaust port through the opening 2 ′, the opening 2 ′ is sealed, and exhaust pressure is reduced from the exhaust port of the storage bag. Vacuum packing method.

Further, the temporary bag 1 is a single-layer bag having a size sufficient to store clothes or bedding, and the storage bag 1'is sufficient to store at least one temporary bag 1 containing compressed clothes or bedding. It is preferable to use a laminated layer having a size of.

A single-layer temporary bag 1 having a size sufficient to store clothes or bedding, including an opening 2 for storing clothes or bedding and an exhaust port for exhausting and decompressing the air inside after closing the opening 2; A bag having a size capable of accommodating clothes or bedding and evacuating and depressurizing the temporary bag 1. The inside air is exhausted after sealing the opening 2'and the opening 2'for storing the temporary bag 1. Laminate layer storage bag 1'with an exhaust port for decompressing
Storage bag for vacuum packing of clothing or bedding.

Here, the temporary bag refers to one in which clothes or bedding stored in the bag can be reduced by decompressing the inside of the bag.

Further, the temporary bag 1 and the storage bag 1 ′ each have at least the opening 2,
The 2'sealing portion is made of a thermoplastic resin material, and the sealing can be performed by heat sealing. The knowledge of the present invention is as follows. It has not been conventionally considered to reduce the size of a bag containing clothes or bedding by reducing the pressure inside the bag (hereinafter referred to as a vacuum) for storage. Based on this idea, the applicant confirmed by conducting various experiments that there is no possibility of causing irreversible shrinkage deformation to these clothes and bedding when pulled in a vacuum, and further used for storage. It solves the economic problem caused by the size and material of the bag suitable for vacuum storage.

As an example of pulling a vacuum on conventional clothes, for the purpose of safe long-term storage such as fur coats, these are stored in a bag of polyethylene or the like in a multilayer and then vacuum is drawn, and then nitrogen is filled to eliminate the pressure difference between the inside and outside The only reason why it was so limited was that
One reason is that there is concern about damage to clothes due to long-term vacuum storage, and that it is extremely expensive when the vacuum storage bag becomes large, and this is because it is economical.

According to the present invention, a method of temporarily storing clothes or bedding in an inexpensive temporary bag made of polyethylene or the like, and storing the clothes or bedding in a storage bag for long-term storage after being reduced by vacuum suction is provided. As a result, the size of the storage bag can be made extremely small. Further, since this storage bag can be made strong in terms of mechanical strength, it can be suitable for transportation and transportation in addition to long-term storage.

[Embodiment] An embodiment of the vacuum packing method according to the present invention will be described with reference to the drawings.

FIG. 1 is a schematic view showing the structure of a thermoplastic resin (polyethylene) auxiliary large bag 1 which is a temporary bag and a storage small bag 1'which is a storage bag used in the present invention. Auxiliary bag has a thickness of 0.05
It has a main body made of a single layer polyethylene bag of ~ 0.1mm and has an opening 2 on one side, and an exhaust port 3 which is also a short tube of polyethylene tube at the corner continuing to the other side.
It is provided on the bag body by heat bonding. On the other hand, the storage pouch 1'has a similar shape and has a thickness of 0.1 to 0.15 mm.
Consisting of laminated layers of layers. The outermost layer and the intermediate layer are made of polyethylene, and the intermediate layer is made of polyvinyl alcohol (bovar) resin for a long-term storage bag with a storage period of less than 1 year, and the storage period is about 6 months. For storage bags, polyvinylidene chloride coat (K coat) is used respectively.

FIG. 2 is a diagram showing a portable vehicle-mounted vacuum pack device 4 which also serves as a bag sealing power supply and a vacuum suction device, which are devices used in the present invention, and their accessories. . The bag sealer 5 as an accessory of the vacuum suction device is composed of two heaters having an elongated rectangular shape, and the heaters are provided with a nichrome wire heater 52 inside and a Teflon coating 53 on the surface. Has been applied. The heating power is supplied to each of the heaters from the vacuum packing device 4 via the power cord 51. The vacuum suction nozzle 6 is a stop valve whose handle is provided on the front surface of the vacuum packing device.
A tube 61 is provided between the suction tube 62 and
The air from is discharged by the vacuum pump 41 housed inside the vacuum pack device 4. The vacuum pump 41 has a capacity of 50 l / min, and the reason why the capacity of the vacuum pump can be set low is that the 100 l vacuum tank 7 is separately provided. The vacuum pump 41 is operated prior to use of the apparatus, and the vacuum tank 7 is always kept in a vacuum state.

Next, the vacuum packing method of the present invention for a futon as an example will be described step by step. After the futon to be stored is stored in the auxiliary large bag 1 of FIG. 1, the opening 2 is sandwiched by the two heaters of the bag sealing device 5 and heat sealed. The auxiliary large bag 1 does not adhere to the heater 52 due to the Teflon coating 53. After the suction tip 62 of the vacuum suction nozzle 6 is inserted into the auxiliary large bag from the exhaust port 3, the exhaust port 3 is sandwiched from above by a sealing clip to prevent air leakage between the exhaust port and the suction nozzle.

When the stop valve 42 on the front surface of the vacuum packing device 4 is opened, the air inside the auxiliary bag 1 is vacuumed by the vacuum tank 7 and the vacuum pump.
Exhausted by 41. As a result, the pressure inside the auxiliary bag is about 600 to 700 mmHg, and the futon volume is 1/4 to 1
Reduce to about / 5. For clothing and blankets, this reduction ratio is 1/3 to 1/4. After drawing the tip 62 of the suction nozzle close to the tip inside the exhaust port 3 while taking care not to leak air, the bag sealing device 5 seals the bag near the inner root of the exhaust port. As a result, the exhaust port 3 is closed and loses its role. Immediately after this, the reduced futon is stored together with the auxiliary large bag 1 in a storage small bag 1'having a predetermined size.

A deoxidizer is stored in the storage bag 1'at the same time. The storage pouch receives air permeation according to the size of the surface area, and therefore permeates 1 to 7 cc of oxygen per 24 hours. For example, 180 cc to 1,260 cc of oxygen permeates into the bag every 6 months. Will be done. Therefore, by using more than the appropriate amount of oxygen scavenger, in the case of the above example, the amount of oxygen absorber that absorbs 2,000 cc of oxygen, the oxygen content inside the bag will be kept substantially 0. ， The worry of insects and molds is eliminated. In addition, since other components in the permeating air are small in amount, the increase in pressure inside the bag does not actually pose a problem.

When the whole of the storage pouch 1'is stored, the opening 2'is sealed via the bag sealing device 5 in the same manner as the auxiliary pouch. In addition, the heating current in the case of this sealing needs to be about twice as large as that in the case of the auxiliary large bag. Further, after evacuation is performed from the exhaust port 3'via the suction nozzle 62, the exhaust port 3'is also closed as in the case of the auxiliary large bag. Futon has an internal pressure of 600m
Since the volume is about 1/5 under a reduced pressure of about mHg, the size of the storage bag 1'is usually 1 / the size of the auxiliary large bag 1.
A size of about 5 is sufficient, and several sizes will be prepared for this purpose. The merit of reduction by this method is that, for example, one futon can be stored in the storage space for five futons, and the size of the laminated heavy bag for storage can be reduced to about 1/5 by using an auxiliary large bag as a temporary bag. It will be clear if you think about it.

It was confirmed that the resilience of clothing and futon after storage could be restored to at least 80% after 3 hours from opening even when stored for 6 months. In the case of a futon, if it is sun-dried, it will be restored to nearly 100%.
Experiments have also confirmed that in the case of short-term storage, it can be restored to 90% or more almost instantly. Therefore, it can be stored by this method without damaging the material except for a very small part of the clothes and futon.

The numbers shown for the vacuum pressure and the like are merely examples, and are not intended to limit the scope of the present invention.

[Effects of the Invention] In the method of the present invention, when storing clothes and bedding, they are temporarily stored in an inexpensive temporary bag, evacuated, vacuumed, and then stored as a whole in a storage bag suitable for long-term storage. With the configuration in which the exhaust port is closed after evacuation, not only the size of clothing and bedding can be reduced, but also vacuum storage can be performed without fear of damage by insects, moisture, mold, etc. Since the size of the storage bag or the bag for transportation can be made extremely small, economical or damage-free long-term or short-term storage and convenient handling of clothes or bedding have become possible.
