The present invention relates to a detergent sheet, a rinse sheet, a portable washing kit, and a washing method for removing dirt adhering to a washing target such as clothes.
Hitherto, in case where dirt adheres to clothes or the like, for example, out of home, the dirt is removed generally by washing with use of detergent, for example, after returning home. See Japanese Patent Application Laid-open No. 2017-184961.
However, in many cases, once the dirt adhering to the clothes or the like penetrates their textiles and solidifies therein over time, the dirt cannot be removed even by the washing with use of detergent thereafter, and remains as a stain.
In addition, the textiles are damaged by repeated attempts to remove the stain with use of detergent.
In such a case, when the attempt to remove the dirt is made with wet wipes in hand, a residue of the dirt remains.
Specifically, the wet wipes are formed by coating spongy pulp with synthetic resin, and hence are hardly soluble. In addition, the wet wipes are designed to wipe off the dirt under a state in which chemical liquid is retained on surfaces of the wipes (wet state).
Thus, chemical liquid is difficult to ooze therefrom, and cannot be applied to an application target by a large amount.
Although the wet wipes physically clean off the dirt, the dirt is inevitably present on their surfaces. Even after the dirt is dissolved by the chemical liquid, the residue remains on the surfaces.
The present invention has been made in view of such circumstances, and an object thereof is to provide a portable washing kit and a washing method with use of which dirt can be immediately and easily cleaned off even out of home.
A portable detergent kit according to a first aspect of the present invention includes:
A washing method according to the first aspect of the present invention includes:
A portable detergent kit according to a second aspect of the present invention includes:
A washing method according to the second aspect of the present invention is implemented by using the portable detergent kit according to the second aspect, the washing method including:
A portable detergent kit according to a third aspect includes:
According to the present invention, the portable cleaning kit and the washing method with use of which dirt can be immediately and easily cleaned off even out of home can be provided.
Below, portable washing kits and washing methods according to embodiments of the present invention are described.

The bar member 33 is formed of a non-water-absorbing member such as plastic or a metal. With this, the liquid cleaner can be prevented from permeating the bar member 33.
The cotton wad portions 35 and 37 are impregnated with the liquid cleaner.
The cotton wad portions 35 and 37 are formed of fibers, and are capable of causing capillary action to retain and ooze the liquid cleaner, thereby applying the liquid cleaner to a washing target.
The cotton wad portions 35 and 37 are each, for example, of a grooved type.
Details of the cotton wad portions 35 and 37 and the liquid cleaner being impregnant therein are described below.
The detergent packet 11 is formed, for example, of an aluminum film.
The liquid cleaner to be used contains, as its components, a bleaching detergent composition containing an organic peracid precursor that reacts with hydrogen peroxide in water to produce an organic peracid having an alkyl group with 7 to 19 carbon atoms and a hydrogen-peroxide releaser, a proteolytic enzyme, sodium bicarbonate, and water.
[Rinse Packet 13]
The rinse packet 13 is waterproof, and holds a rectangular rinse sheet therein. When using, a user unseals the rinse packet 13, for example, with his/her fingers, and takes out the rinse sheet.
This rinse sheet is made of a water-absorbing material such as fibers of cotton or the like, and is capable of causing the capillary action to retain and ooze the liquid cleaner, thereby applying rinse liquid to the washing target.
The rinse sheet has a three-layer structure including a cotton layer 23, a cotton PET layer 25, and another cotton layer 27.
The rinse sheet is impregnated with the rinse liquid. The rinse liquid to be used contains, as its components, for example, preservative containing at least one of benzazirconium chloride and citric acid, and water.
An amount of the impregnation of the rinse sheet with the rinse liquid is, for example, 8 ml to 12 ml.
[Support Sheet 15]
The support sheet 15 is a water-absorbing sheet to be used for sandwiching, after the liquid cleaner is applied from the cotton swab 31 to a spot on the washing target that has got dirt on the spot, the washing target between the support sheet 15 and the rinse sheet at a time when the rinse sheet is pressed against the dirt spot.
The support sheet 15 is made, for example, of pulp.
The support sheet 15 is packed, for example, in a transparent waterproof packet.
[Holder 21]
The holder 21 is formed, for example, of a single sheet, and includes two folding portions 23 and 25 located at a predetermined distance in its longitudinal direction. The holder 21 is folded in three by being divided by the folding portions 23 and 25 into a first holder-sheet portion 41, a second holder-sheet portion 42, and a third holder-sheet portion 43 arranged in the stated order.
A holding portion 47 that holds the detergent packet 11, the rinse packet 13, and the support sheet 15 is formed in the first holder-sheet portion 41.

[Washing Method]
Below, a use method (washing method) for the portable washing kit 1 is described.
The portable washing kit 1 is suited to removing a stain of approximately 5 cm square on clothes, for example, out of home.
In case where dirt (stain) adheres to the washing target, the user brings the portable washing kit 1 into the open state, and takes out and unseals the detergent packet 11, thereby taking out the cotton swab 31 therefrom.
Then, the user presses the cotton wad portions 35 and 37 of the cotton swab 31 against a spot on the washing target that has got the dirt on the spot.
In this way, the dirt on the washing target becomes dirt that is hydrolyzed by the liquid cleaner being the impregnant in the cotton wad portions 35 and 37 and trapped by the liquid cleaner.
Next, the user takes out the rinse packet 13 and the support sheet 15 from the portable washing kit 1. After that, the user unseals the rinse packet 13, and takes out the rinse sheet therefrom.
Then, the user sandwiches the washing target between the rinse sheet and the support sheet 15, and presses the rinse sheet against the washing target.
In this way, the rinse liquid is oozed from the rinse sheet into the washing target, and the liquid cleaner trapping the dirt is mixed into the rinse liquid.
Then, the rinse liquid in which the liquid cleaner trapping the dirt has been mixed is absorbed into the support sheet 15. By repeating this operation, substantially all the rinse liquid is absorbed into the support sheet 15.
As described above, in the portable washing kit 1, the holder 21 accommodates the detergent packet 11, the rinse packet 13, and the support sheet 15 in its portable size. Thus, the user can easily clean off the dirt adhering to the clothes or the like out of home.
Further, by using the portable washing kit 1, specifically, by pressing the cotton wad portions 35 and 37 of the cotton swab 31 packed in the detergent packet 11 against the dirt spot, the liquid cleaner being the impregnant in the cotton wad portions 35 and 37 can be applied only to the dirt spot. With this, the stain of approximately 5 cm square on the clothes can be effectively cleaned off.
