Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique of suspending a water-permeable bag containing powdered soap, shavings, dried sardines, etc. in water.

[0002]

2. Description of the Related Art Soap powder has few environmental hygiene problems,
In addition, since it enables reuse of resources, it is preferably used widely. Since laundry detergents used at home are predominantly synthetic detergents, the usage of powdered soap naturally follows that of synthetic detergents, and the powdered soap is weighed with a cup and then placed in the washing tub.

When the shavings are taken out, the shavings are left as they are or put in a water-permeable bag and poured into hot water.

[0004]

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In the soap powder used in this manner, particles of the soap powder are not easily dissolved in water as a lump in water, and when the lump adheres to laundry, it takes time to rinse. There is a problem that it takes a lot of water.

In addition, it may take time and effort to recover the scraped-out knot after removing it from the water. Shavings placed in a water-permeable bag can cause the bag to sink in the water. If the pot or other container used for taking out the container is large, it may take some time to collect the sunk bag.

An object of the present invention is to make such a powdered soap easy to use in a washing machine and to save time and trouble when taking out the soap.

BEST MODE FOR CARRYING OUT THE INVENTION Floating in water according to the present invention
Taking as an example a water-permeable bag for powder soap, the details of the water-permeable bag will be described below with reference to the accompanying drawings.

[0017] Figure 1 and 2, the bag 1 is one example of a water-permeable bag
2 is a partially cutaway perspective view and a sectional view taken along line II-II of FIG. 1. The bag 1 is a bag body portion 1A for containing powdered soap,
It is composed of a floating storage portion 1B and a float 9 that is stored in the storage portion 1B. The main body portion 1A and the storage portion 1B are integrally formed by a water-permeable sheet made of thermoplastic synthetic resin, and one rectangular sheet is folded along a folding curve 3 that bisects its longitudinal direction. The overlapping and overlapping sheets are joined at a side edge of the bag 1 at a first welding line 2A extending in the vertical direction and a second welding line 2B extending in the width direction in parallel with the folding curve 3. In the portion 10 outside the first welding line 2A, the overlapping sheets are in a non-bonded state.

The main body portion 1A has a pair of first and second side walls 4 and 5 facing each other and a top opening 31, and the bottom of the bag is formed by the second welding line 2B. The first and second side walls 4, 5 are not joined in the vicinity of their upper edges 4A, 5A, so that the opening 31 can be expanded into a V-shape as shown when viewed from the side. In the sheet forming the bag 1, the first and second extension portions 6 and 7 extending beyond the upper edges 4A and 5A of the first and second side walls 4 and 5 are folded back to the outside of the bag 1 to form the first welding line. Second welding line 2 located on the extension of 2A
In C, the first pocket 17 and the second pocket 18 that open downward are formed by joining the side edges of the first and second side walls 4 and 5.

The storage portion 1B includes a folding curve 3 of the bag 1 and a second
A part of the normally closed bag defined by the welding line 2B and the fourth welding line 2D extending downward from the first welding line 2A, in which the float 9 is housed.

The water-permeable sheet forming the bag 1 enables the infiltration of water into the main body 1A and the exudation of the powdered soap dissolved in the infiltrated water from the main body 1A. A cloth, a net, a perforated plastic film or the like, which is water-permeable, is used. The water-permeable sheet is preferably made of a thermoplastic synthetic resin so that it can be joined to each other by welding.

The float 9 is a means for imparting a buoyancy force for floating the bag 1 containing the powdered soap in the main body portion 1A in water, and is preferably made of foamed plastic such as foamed polyethylene, foamed polystyrene or urethane sponge. The product is used. Instead of foamed plastic, a piece of wood or a small balloon inflated with air can also be used as a means for imparting buoyancy to the bag 1.

3 and 4 are a plan view of the bag 1 in which the powdery soap 100 is put and then the opening is closed, and a sectional view taken along line IV-IV thereof. To close the bag 1, the corner portion 32 (see also FIG. 1) of the main body portion 1A is bent in the directions of arrows P and Q so that the first extension portions 6 overlap each other. At the same time as the bend,
Alternatively, after the bending, the second extension 7 is turned over to form a third pocket 18B that opens downward, and the top of the first side wall 4 and the first extension 6 are housed in the third pocket 18B ( (See FIG. 4).

When the bag 1 shown in FIG. 4 is placed in a water tank of a washing machine, it dissolves in the water into which the powdery soap 100 has infiltrated while floating in water and gradually exudes out of the bag 1 to wash the laundry. The dirt can be removed. The water-insoluble powder soap 100 does not get out of the bag 1 and therefore does not adhere to the laundry. Therefore, there is no need to use a lot of water for rinsing the laundry and take a long time as in the conventional case.
In the bag 1, the first to fourth welding lines 2A to 2D may be parts having relatively high rigidity. However, in this bag 1, the first, third and fourth welding lines 2A, 2 extending to the side edge portion of the bag 1 are used.
Since there is a non-welded flexible sheet portion 10 outside C and 2D, the rigid welding lines 2A, 2C and 2D do not get caught on the laundry and hurt it.

5 and 6 are drawings similar to FIGS. 1 and 2 showing an example of the embodiment of the present invention. In this bag 1, the bottom portion of the bag body portion 1A is formed by bending a water-permeable sheet along folding lines 3A and 3B, and a portion 1 for accommodating the float 9 is formed.
B is formed near the top opening 3. Body part 1
The bottom of A is bent so that the cross section has a W shape. The storage portion 1B includes the first pocket 17 shown in FIG.
After the float 9 is put in the pocket 17 by using the above, the first extension 6 of the first side wall 4 is joined to the side wall 4 by the fifth welding line 2E extending in the width direction of the main body portion 1A, and the opening is opened. Just close it.

FIG. 7 is a drawing similar to FIG. 4 when the soap 1 is put into the bag 1 of FIGS. 5 and 6 and closed. This bag 1
Then, by putting powdered soap 100, the main body 1
The bottom of A spreads out, and has good stability when placed on a flat object 101. In order to close the opening 3, the float 9 contained in the storage portion 1B is stored in the third pocket 18B obtained by turning over the second extension portion 7. Since the third pocket 18B swells due to the float 9, the sheet forming the storage portion 1B and the sheet forming the second extension portion 7 are relatively strongly adhered to each other, and the soap powder 100 remains as powder and both of them remain. It can prevent going out between the seats.

FIG. 8 is a drawing similar to FIG. 2 showing an example of the embodiment of the present invention. In this bag 1, the first extension 6 of the first side wall 4 is bent inside the bag 1, and the second extension 7 of the second side wall 5 is bent outside of the bag 1. Top opening 3
To close 1, reverse the second extension 7 to create a third pocket similar to that of FIG. 3 and insert the first side wall 4 into the pocket.
And the first extension portion 6 may be inserted. Since the sheets forming the first side wall 4 and the first extension portion 6 are overlapped with each other, the rigidity of the sheet in the portion to be put in the pocket is increased, and the work of inserting the sheet is facilitated. However, in this embodiment, if there is no such need, it is possible to carry out the present invention without the first extension portion 6.

In the illustrated example of the invention, the first and second side walls 4,
Although the side edge portion of No. 5 is in a non-bonded state in the vicinity of the top opening 31, the present invention can be carried out in a state in which all the side edge portions of the first, second side walls 4, 5 are bonded to each other. Further, in the present invention, the means for opening and closing the top opening 31 is not limited to that shown in the drawings. For example, the first and second side walls 4 and 5 may be provided with opening / closing means such as tape fasteners that are engaged and disengaged from each other to implement the present invention. When using a non-woven fabric with a relatively small basis weight and a large fiber gap as the water-permeable sheet, use two or more non-woven fabrics so that the soap powder does not leak from the gap as powder. You can also

In the present invention, if shavings or dried sardines are put in the bag 1 instead of the powdery soap 100 and taken out, the bag 1 is suspended in the final water, so that the bag 1 can be easily collected.

[0029]

According to the present invention, the powdery soap is put in a water-permeable bag, and the bag is floated in the water so that the powdery soap does not remain in the laundry in the form of particles. , It takes less time to rinse laundry with soap powder and less water is required. If shavings and the like are put into this bag and taken out, the shavings can be easily collected.
