Description

Stick cleaner {stick cleaner}

The present invention relates to a stick-type cleaner, and more specifically, to a stick-type cleaner that can easily remove and clean contamination on a surface to be cleaned without getting it on one's hands, thereby enhancing convenience in use.

When removing dirt from a floor, table, or car, it is common to use a cleaning towel or cloth designed for that purpose.

Cleaning towels and cloths come in a variety of sizes, from disposable to those that can be washed and used multiple times. Recently, microfiber and ultrafine fiber cleaning towels with added functionality have become more widespread.

However, since workers have to hold and use regular cleaning towels or cloths with their hands, their hands inevitably get contaminated, which reduces convenience in use. Therefore, there is a growing need for an improved stick-type cleaner.

Hereinafter, a preferred embodiment of the present invention will be described with reference to the attached drawings.

FIG. 1 is an actual product image of a stick-type cleaner according to a first embodiment of the present invention, FIG. 2 is a back image of FIG. 1, FIG. 3 is a drawing of FIG. 1, FIGS. 4 to 6 are drawings showing FIG. 3 from different angles, FIG. 7 is an exploded perspective view of FIG. 3, FIG. 8 is a partial cross-sectional structural view of FIG. 3, and FIGS. 9a to 9d are comparative examples before and after use.

Referring to these drawings, the stick-type cleaner (1) according to the present embodiment can easily remove and clean contamination on a surface to be cleaned without getting it on one's hands, thereby increasing convenience in use, and may include a cleaning foam (100), a stick (140), and a detachable coupling part (150).

The cleaning foam (100) is a means for easily removing and cleaning contamination on the surface to be cleaned. Contamination can be wiped off, and moisture can be absorbed. In particular, since the cleaning foam (100) is used by holding the stick (140), it does not get dirty, and the convenience of use can be greatly improved.

This cleaning foam (100) is made of an elastic material and includes a foam body (110) that is pressed against a surface to be cleaned to remove contamination on the surface to be cleaned, and a plurality of embossed protrusions (120) that are formed protrudingly on at least one surface of the foam body (110) and increase the contact area with the surface to be cleaned.

The foam body (110) includes a main body (111) having a plurality of embossed protrusions (120) formed on one surface, and a sub body (112) that is detachably laminated and joined to the main body (111) but formed with a thickness smaller than that of the main body (111) and provides rigidity to the main body (111), and has a different color from the main body (111).

Although the main body (111) actually plays a role in wiping off contamination or absorbing moisture, the sub body (112) also has some moisture absorption function. The materials of the main body (111) and the sub body (112) may be the same or different. In the latter case, the main body (111) and the sub body (112) can be manufactured separately and then bonded together.

In particular, the main body (111) of the foam body (110) can be manufactured using a conventional sponge material. For example, the main body (111) of the foam body (110) can be manufactured using a material such as melamine resin foam.

If the main body (111) of the foam body (110) is made of sponge material or melamine resin foam, the efficiency of removing contamination on the surface to be cleaned increases. In addition, since it easily absorbs moisture, the wet cleaning surface can be easily wiped off.

The embossed protrusion (120) is formed protrudingly on one surface of the foam body (110) and serves to increase the contact area with the surface to be cleaned. The embossed protrusion (120) is provided in multiple pieces as shown in the drawing.

In this embodiment, a plurality of embossed protrusions (120) are formed on one side of the foam body (110). The embossed protrusions (120) are provided at equal intervals. In addition, in this embodiment, the protrusion heights of the embossed protrusions (120) are the same.

As described above, these embossed protrusions (120) increase the contact area with the surface to be cleaned. Therefore, when the surface with the embossed protrusions (120) is placed against the surface to be cleaned and pressed against it while cleaning, contamination on the surface to be cleaned can be removed relatively easily, and moisture, etc. can be easily wiped off.

The stick (140) is a tool for using the cleaning foam (100). This stick (140) may include a handle portion (141) that the user holds and handles, and a connecting plate (142) that forms one side of the handle portion (141) and is connected to the cleaning foam (100). A hole (143) is formed at the end of the handle portion (141). A ring can be hung through the hole (143). The connecting plate (142) forms a place where the detachable coupling portion (150) is placed.

The detachable coupling part (150) is a means for detachably coupling the connecting plate (142) of the stick (140) to the cleaning foam (100).

This detachable joint (150) includes a first Velcro sheet (151) having one side joined to the cleaning foam (100), and a second Velcro sheet (152) having one side joined to the connecting plate (142) of the stick (140) and the other side detachably joined to the other side of the first Velcro sheet (151).

It is preferable that one side of the first Velcro sheet (151) be detachably connected to the cleaning foam (100) so that it can be used multiple times. It is also preferable that one side of the second Velcro sheet (152) be detachably connected to the connecting plate (142) of the stick (140) so that it can be used multiple times.

The structure of the first Velcro sheet (151) and the second Velcro sheet (152) allows the connecting plate (142) of the stick (140) to be detachably connected to the cleaning foam (100), thereby greatly improving the convenience of use. In other words, the cleaning foam (100) that has been used can be discarded and replaced with a new one.

In the case of the present embodiment described above, as shown in comparative examples in FIGS. 9a to 9d, not only can stains be easily removed and cleaned, but also the stained form can be easily removed again by washing with water, making it easy to wash and reuse the product. For reference, in FIGS. 9a to 9d, the left side is an image of a clean product before use, and the right side is an image of a product with stains or dirt after use.

According to this embodiment, which operates based on the structure described above, contamination on a surface to be cleaned can be easily removed and cleaned without getting it on the hands, thereby increasing convenience in use.

FIG. 10 is a plan view of a large-area disc foam connected to a cleaning foam applied to a stick-type cleaner according to the second embodiment of the present invention.

The cleaning foam (100) introduced in the above-described embodiment has a small size. Therefore, it is suitable for use in narrow spaces and is also easy to dispose of.

However, since individually manufacturing these cleaning forms (100) may result in increased costs, a large-area disc form (280) is applied in this embodiment.

That is, the cleaning foam (100) introduced in the above-described embodiment can be formed separately from the large-area disc foam (280). At this time, a plurality of cutting lines (281) are formed in the large-area disc foam (280) to easily cut and remove the cleaning foam (100) introduced in the above-described embodiment. Therefore, the cleaning foam (100) can be easily obtained even without scissors or a knife.

Even if this embodiment is applied, it is possible to easily remove and clean contamination on the surface to be cleaned without getting it on your hands, thereby increasing convenience in use.

FIG. 11 is an exploded perspective view of a stick-type cleaner according to a third embodiment of the present invention, and FIG. 12 is an enlarged structural view of area A of FIG. 11.

Referring to these drawings, the stick-type cleaner (1a) according to the present embodiment may also include a cleaning foam (100), a stick (140), and a detachable coupling part (350). The structures of the cleaning foam (100) and the stick (140) are the same as those of the first embodiment described above. Therefore, a duplicate description is omitted.

Meanwhile, in the present embodiment, the detachable coupling part (350) includes a first Velcro sheet (351) having one side coupled to the cleaning foam (100), and a second Velcro sheet (352) having one side coupled to the connecting plate (142) of the stick (140) and the other side detachably coupled to the other side of the first Velcro sheet (151). At this time, the areas of the connecting plate (142) of the stick (140), the first Velcro sheet (351), and the second Velcro sheet (352) are manufactured to be identical.

Additionally, a functional non-woven fabric layer (340) is interposed between the connecting plate (142) of the stick (140) and the cleaning foam (100).

The functional nonwoven layer (340) is laminated on the opposite side of the embossed portion (120) with respect to the foam body (110) so as not to interfere with the first Velcro sheet (151). A penetration portion (340a) is formed in the functional nonwoven layer (340) so as not to interfere with the first Velcro sheet (151). The penetration portion (340a) is smaller than the area of the first Velcro sheet (151). Therefore, when the first Velcro sheet (151) is combined with the cleaning foam (100) through the penetration portion (340a), it can also play a role of supporting the functional nonwoven layer (340).

The functional nonwoven layer (340) itself has a cleaning function that removes foreign substances such as dust and dirt. Therefore, the functional nonwoven layer (340) is formed in a sheet type with a thickness smaller than that of the foam body (110), that is, very thin, and can be adhesively bonded to the foam body (110).

This functional nonwoven fabric layer (340) includes a nonwoven fabric sheet body (341) made of polypropylene (PP), a plurality of foreign substance-catching irregularities (342) formed on an exposed surface of the nonwoven fabric sheet body (341) for foreign substance-catching, a foreign substance-catching space (343) formed between the foreign substance-catching irregularities (342) and in which the captured foreign substances are trapped, and a static electricity-generating fluffy portion (344, 345) forming the end portion of the foreign substance-catching irregularities (343) and maximizing the generation of static electricity.

In this structure, the length of the first static electricity generating fluffy part (344) on one side is formed shorter than the length of the second static electricity generating fluffy part (345) on the other side based on one foreign matter capturing uneven part (342). Accordingly, discharge of foreign matter captured in the foreign matter capturing space (343) can be naturally prevented.

Even if this embodiment is applied, it is possible to easily remove and clean contamination on a surface to be cleaned without getting it on one's hands, thereby increasing convenience in use.

In particular, in the case of the present embodiment, after the foam body (110) is used, when the foam body (110) is removed and discarded, other contaminated areas can be wiped off with the functional non-woven fabric layer (340) and then discarded, so that cleaning efficiency can be increased.

Fig. 13 is a partial cross-sectional structural diagram of a stick-type cleaner according to the fourth embodiment of the present invention.

Referring to this drawing, the stick-type cleaner (1b) according to the present embodiment may also include a cleaning foam (400), a stick (140), and a detachable coupling portion (150). As in the above-described embodiment, the cleaning foam (400) is composed of a foam body (410) and a plurality of embossed protrusions (120).

Meanwhile, in this structure, a finger insertion portion (470) for inserting a finger is formed in the foam body (410). At this time, the end of the finger insertion portion (470) has a closed structure.

When a finger insertion portion (470) is formed in the foam body (410) as in this embodiment, it can be advantageous to forcefully remove contaminants that are difficult to remove by inserting a finger into the portion and strongly pressing the embossed protrusion portion (120).

In addition, when removing the cleaning foam (400) that has been used from the stick (140), it can be used to easily remove the cleaning foam (400) that has been used from the stick (140) without contaminating the hands.

Even if this embodiment is applied, it is possible to easily remove and clean contamination on a surface to be cleaned without getting it on one's hands, thereby increasing convenience in use.

FIG. 14 is a cross-sectional view of a cleaning foam area in a stick-type cleaner according to the fifth embodiment of the present invention.

Referring to this drawing, in the present embodiment, as in the first embodiment, the cleaning foam (500) is made of an elastic material and includes a foam body (510) that contacts and presses against a surface to be cleaned to remove contamination on the surface to be cleaned, and a plurality of embossed protrusions (520) that are protruded on one surface of the foam body (510) and increase the contact area with the surface to be cleaned.

In this structure, the embossed protrusions (520) are provided with different protrusion heights. That is, the embossed protrusions (520) are provided with a greater protrusion height from the center area to the side area. This cleaning form (500) can be particularly effective when used on a surface that is not flat but curved.

Even if this embodiment is applied, it is possible to easily remove and clean contamination on a surface to be cleaned without getting it on one's hands, thereby increasing convenience in use.

FIG. 15 is a cross-sectional view of a cleaning foam area in a stick-type cleaner according to the sixth embodiment of the present invention.

Referring to this drawing, the cleaning foam (600) according to the present embodiment is substantially the same as the cleaning foam (700) of the fifth embodiment. That is, the embossed protrusions (620) provided on one side of the foam body (610) are provided such that the protrusion height increases as it goes from the center region to the side region.

Meanwhile, in this structure, additional dummy protrusions (621) are formed protruding from each of the embossed protrusions (620). When the size of the embossed protrusion (620) is small, one dummy protrusion (621) may be formed, and when the size of the embossed protrusion (620) is large, two or more dummy protrusions (621) may be formed. These dummy protrusions (621) can increase the contact area with the surface to be cleaned together with the embossed protrusion (620), thereby contributing to improving the cleaning efficiency.

Even if this embodiment is applied, it is possible to easily remove and clean contamination on a surface to be cleaned without getting it on one's hands, thereby increasing convenience in use.

As such, the present invention is not limited to the described embodiments, and it is obvious to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the present invention. Accordingly, such modifications or variations should be considered to fall within the scope of the claims of the present invention.
