The plurality of partition walls 18 are provided to extend from the one end in the axial direction of the suction nozzle body 12 to the other end side by a predetermined length in parallel with the axis of the suction part 14. Each of the plurality of partition walls 18 is formed, for example, in a rectangular plate shape in cross section, and is formed apart from each other. A plurality of quadrangular suction ports 20 are provided on one end side of the suction section 14 in the axial direction by the plurality of partition walls 18.

Further, a plurality of, for example, circular through holes 22 are provided on the peripheral wall surface of the suction unit 14 at predetermined intervals in the circumferential direction. Each of the plurality of through-holes 22 is provided as a through-hole penetrating the peripheral wall surface (outer wall surface) of the suction unit 14 and communicating with the inside of the suction unit 14. Further, the suction unit 14 is provided with a mounting portion 24 for mounting a suction assisting tool 30 described later to the suction nozzle 10. The mounting portion 24 is formed, for example, in a cylindrical shape, and is disposed at a part of the plurality of suction ports 20.

A connection portion 16 is connected to the other end of the suction nozzle body 12 in the axial direction. The connecting portion 16 is formed, for example, in a substantially frustoconical cylindrical body tapering from one end to the other end in the axial direction. That is, the connecting portion 16 is formed with a tapered portion 16a that tapers from the axial center to the other axial end. In this case, since the connecting portion 16 is formed in a tapered substantially frustoconical cylindrical body, the other end of the suction nozzle 10 in the axial direction is a hose having a function as a suction portion of a vacuum cleaner (not shown). This facilitates the work of inserting and connecting to suction ports (not shown) such as pipes and extension pipes.

A suction assisting device 30 is detachably mounted on the mounting portion 24 of the suction portion 14. FIG. 3 is a plan view showing an example of a suction assisting device that can be attached to the suction portion of the suction nozzle of the compression storage bag according to the present invention, and FIG. 4 is a cross-sectional view taken along line IV-IV in FIG. The suction aid 30 includes a tubular pipe body 32. At one end of the pipe body 32 in the axial direction, for example, a U-shaped tubular hook portion 34 is formed. The pipe main body 32 and the hook portion 34 are integrally formed of a synthetic resin material such as high-pressure poly. The length of the pipe body 32 in the axial direction is, for example, as shown in FIG. 9, when the suction assisting tool 30 is mounted on the suction nozzle 10 of the compression storage bag, the outer valve portions 56 a, It is formed to be longer than the length of the valves 48a, 48b so as to protrude outside from 56b. In this embodiment, the pipe main body 32 and the hook portion 34 are formed to have, for example, an outer diameter of 7 mm and an inner diameter of 5 mm. The length of the pipe body 32 in the axial direction is, for example, 280 mm, and the length of the hook portion 34 is, for example, 70 mm.

The suction assisting device 30 is detachably mounted on a locking portion 24 provided on a part of the suction portion 14 of the suction nozzle body 12. In this embodiment, in particular, as shown in FIG. 1, the locking portion 24 is formed in a cylindrical shape, for example, and is disposed at one end in the axial direction of the suction portion 14 and at one end in the diameter direction thereof. The inner diameter of the locking portion 24 is formed slightly larger than the outer diameter of the hook portion 34 of the suction assisting device 30. The suction assisting device 30 can be detachably attached to the suction nozzle 10 of the compression storage bag by inserting the hook portion 34 into the locking portion 24 of the suction portion 14 and locking the same.

The suction nozzle 10 of the compression storage bag according to the present invention and the suction assisting device 30 which can be detachably attached to a part of the suction portion 14 thereof are, in particular, a futon (including a duvet), a blanket, and a thick cloth. It is applied to a compression storage bag 40 for compressing and storing items such as clothing. FIG. 5 is a plan view showing an example of a compression storage bag to which the suction nozzles of FIGS. 1 and 2 are applied, FIG. 6 is a cross-sectional view taken along line VI-VI of FIG. 5, and FIG. It is sectional drawing in line VII-VII. FIG. 8 is an illustrative view showing a main part of the operation state of the compression storage bag shown in FIGS. 5, 6 and 7. The compression storage bag 40 includes a flat storage bag 44 having an opening 42. The storage bag body 44 is formed, for example, in a rectangular shape in plan view. The storage bag body 44 is formed of a non-breathable synthetic resin material that does not allow air to pass through. The opening 42 is formed at one end in the length direction of the storage bag body 44 and from one end to the other end in the width direction. The storage bag body 44 stores, through the opening 42, storage items such as a futon (including a duvet), a blanket, and thick clothing.

The storage bag body 44 includes a base material 46 having a rectangular shape in a plan view and a thickness of, for example, 80 μm. The base material 46 has a so-called laminate structure in which a plurality of non-breathable plastic films are stacked and bonded. In this embodiment, for example, a plastic film using four materials, eval, polyethylene, nylon and linear lauren, is used. The base material 46 is formed by sequentially laminating EVAL, polyethylene, nylon, polyethylene and linear lauren in this order. In this case, the base material 46 is laminated so that polyethylene is arranged on both sides of nylon. Air leakage is prevented by protecting the nylon surface with polyethylene. In addition, EVAL is laminated on the inner surface of the storage bag body 44 and on the surface of the base material 44 which is the surface to be welded with an iron or the like.

[0015] Eval has a low melting temperature, and thus is easily welded at low and medium temperatures. Polyethylene has an appropriate strength as a surface protective film. Since nylon does not allow air to pass through, it has excellent insulation properties in vacuum packaging. Linear Lauren has tenacity and therefore has weather resistance to bending and scratches. For these plastic films, 100% virgin material is used, and no recycled material is used. Therefore, there is no fear of air leakage as compared with a plastic film using a recycled synthetic resin material, and the soft touch is achieved. In addition, the base material 46 is appropriately subjected to insect repellent, fungicide and deodorant treatment. The lamination method of these plastic films includes a dry lamination method, a hot melt lamination method, an extrusion lamination method, and a co-extrusion lamination method using a plurality of extruders, and can be appropriately selected.

The base material 46 is formed in, for example, a flat cylindrical shape, and is formed as the storage bag body 44 by welding one opening in the length direction thereof. Further, the storage bag body 44 may be formed by, for example, stacking two base materials 46 and heat-welding or bonding the peripheral portion except for one end in the length direction.

The storage bag 44 is formed with, for example, two valves 48 a and 48 b. The valves 48a and 48b are formed in a flat tubular shape from, for example, a plastic film having the same laminated structure as the base material 46. The valves 48a and 48b are formed by the same manufacturing method as that of the storage bag body 44. The valves 48a and 48b are disposed at the other end in the length direction of the storage bag body 44 and at both ends in the width direction thereof. The valves 48a and 48b are disposed such that one end in the length direction extends into the storage bag body 44 and the other end in the length direction extends outside the storage bag body 44, respectively. The hole 50a of the valve 48a and the hole 50b of the valve 48b communicate the inside and the outside of the storage bag body 44, and the holes 50a and 50b suck and deaerate air from the inside of the storage bag body 44, respectively. Thus, the inside of the storage bag body 44 is formed as a decompression port for bringing the inside of the storage bag body 44 into a negative pressure state (decompression state).

The storage bag body 44 has attachment portions 52a and 52b for attaching the valves 48a and 48b. The attachment portions 52a and 52b are formed at the other end in the length direction of the storage bag body 44 and at both ends in the width direction. The attachment portions 52a and 52b are formed by cutting holes 54a and 54b obtained by diagonally cutting both ends of a side of the storage bag body 44 facing the opening 42, for example. The cutting holes 54a, 54b are formed slightly larger than the width of the valves 48a, 48b. The valves 48a and 48b are attached to the storage bag body 44 by being inserted through and fixed to the attachment portions 52a and 52b, respectively. Each of the valves 48a and 48b has an outer surface at an intermediate portion in the length direction fixed to an inner surface of the storage bag body 44 by welding, bonding, or the like. In this case, the valves 48a and 48b are fixed to the storage bag body 44 so that the holes 50a and 50b are not closed.

Therefore, the valves 48 a and 48 b have an outer valve portion 56 a and 56 b disposed outside the storage bag 44 and an inner valve portion 58 a and 58 b disposed inside the storage bag 44, respectively. Is formed. The length of the outer valve portions 56a and 56b is formed to be appropriately longer than the length of the inner valve portions 58a and 58b. When the inside of the storage bag body 44 is suctioned and deaerated, as shown in FIG. 9, the suction nozzle 10 of the compression storage bag according to the present invention is inserted from the outer valve portions 56a, 56b to the inner valve portions 58a, 58b. The connection part 16 of the suction nozzle 10 is connected to a suction port 120 of a suction part such as a hose, a pipe and an extension pipe of a vacuum cleaner (not shown). When the inside of the storage bag body 44 is sucked and evacuated, for example, as shown in FIG. 8, the inner surfaces of the inner valve portions 58a and 58b are tightly closed to each other, so that the holes 50a and 50b of the valves 48a and 48b are closed. Closed. That is, the inner valve portions 58a and 58b have a function of blocking the inflow of outside air into the storage bag body 44.

Next, the work process of putting the duvet 100 (storage material) into the compression storage bag 40 and compressing and storing it, for example, using the suction nozzle of the compression storage bag according to the present invention will be described with reference to FIGS. This will be described with reference to FIGS. First, a duvet (not shown) is folded into the compression storage bag 40 and is inserted through the opening 42 of the storage bag body 44. Then, the duvet is moved toward the valves 48a and 48b, and the edges of the openings 42 are aligned. Further, the edge of the opening 42 of the storage bag body 44 is slowly pressed at a middle and low temperature by a heating device such as an iron, and is thermally welded as shown in FIG. Therefore, the opening 42 of the storage bag body 44 is sealed. The end of one valve 48b is heat-sealed in advance and hermetically sealed.

Then, as shown in FIG. 9, the suction nozzle 10 is inserted into the outer valve portion 56a of the other valve 48a. The suction nozzle 10 is connected in advance by inserting its connection portion 16 into a suction port 120 of a suction portion such as a hose or a pipe of a vacuum cleaner (not shown). In this embodiment, in particular, the suction assisting tool 30 is attached to the suction nozzle 10. The hook portion 34 of the suction assisting tool 30 is inserted into the locking portion 24 provided on the suction portion 14 of the suction nozzle 10 and locked. Further, the suction nozzle 10 is inserted into the outer valve portion 56a of the other valve 48a with the suction aid 30 attached. In this case, the suction nozzle 10 to which the suction assisting device 30 is attached is configured such that the other end in the axial direction of the pipe body 32 of the suction assisting device 30 projects from the outer valve portion 56a to the outside of the storage bag body 44. Inserted into the portion 56a.

Then, the air in the storage bag 44 is suctioned and deaerated by a vacuum cleaner, so that the pressure in the storage bag 44 can be reduced to a negative pressure state. At this time, since the inner surfaces of the inner valve portion 58a of the valve 48a are in close contact with each other, the storage bag body 44 is sealed. As the pressure in the storage bag 44 is reduced by the suction / aeration operation, the outer shape of the storage bag 44 becomes smaller, and the storage bag 44 and the duvet stored therein are compressed. Thereafter, the suction nozzle 10 is pulled out of the outer valve portion 56a of the valve 48a, the wrinkles of the outer valve portion 56a are extended, and the end of the outer valve portion 56a is welded with a heating device such as an iron, so that the hole of the valve 48a is opened. 50a is completely sealed. Thus, the duvet stored in the storage bag body 44 is compressed and stored.

In the suction nozzle 10 of the compression storage bag according to the present invention, a plurality of suction ports 20 defined by a plurality of partitions 18 are formed in the suction portion 14 of the suction nozzle body 12. Compared to the case where the suction nozzle 1 of the conventional vacuum cleaner shown in FIG. 17 is used, the side cloth of the duvet or the inner surface of the compression storage bag 40 is sucked into the entire suction section 14 during the suction and deaeration work. There is no intrusion. This is because even if the side fabric of the duvet or the inner surface of the compression storage bag 40 is attracted to the suction portion 14 of the suction nozzle body 12, any one of the plurality of suction ports 20,. This is because, since is opened, suction and deaeration can be performed from the opened portion. Further, since the plurality of suction ports 20 are arranged in a lattice, suction and deaeration can be performed more effectively.

Further, in the suction nozzle 10 of the compression storage bag according to the present invention, since a plurality of through-holes 22 communicating with the inside of the suction part 14 are provided on the peripheral wall of the suction part 14, Can also be suctioned and degassed.

Further, in the suction nozzle 10 of the compression storage bag according to the present invention, since the suction assisting tool 30 is detachably attached to a part of the suction portion 14 of the suction nozzle main body 12, the pipe of the suction assisting tool 30 is attached. The inside and outside of the storage bag body 44 are ventilated by the main body 32 and the hook portion 34, and an air inflow passage is formed. Therefore, even if the vacuum cleaner is driven for a long time, no load is imposed on the motor of the vacuum cleaner. For this reason, even if the user stands in the middle of something during the suction and deaeration work, the user must perform the compression and storage work continuously for a long time without turning off the vacuum cleaner switch each time. Can be.

In the above-described embodiment, the suction assisting device 30 is detachably formed. However, the suction assisting device 30 is configured so as to be integrally formed with the locking portion 24 of the suction portion 14. It may be done. Further, although the suction portion 14 of the suction nozzle 10 is formed in an elliptical cylindrical shape, the suction portion 14 may be formed in another rectangular tube shape such as a cylindrical shape, a quadrangular cylindrical shape, or the like. The plurality of suction ports 20 partitioned by 18 may also be formed in a polygon other than a quadrangle, for example, a polygon such as a triangle, a pentagon, or a circle, an ellipse, or another shape. Further, the suction assisting device 30 may be formed in a rectangular tube shape other than the cylindrical shape, for example, a triangle, a quadrangle, or another polygonal cross section. The shape of the locking portion 24 provided on the 14 may be appropriately changed.
