Description

  The present invention relates to a kitchen sponge as a cleaning tool used in a home kitchen or a restaurant kitchen.

For kitchen sponges composed of a single block sponge body such as urethane foam, sliding cleaning operation is performed with the smooth outer surface of the flexible sponge body directly against the surface to be cleaned such as dishes. Therefore, there is a problem that the scraping performance with respect to the dirt adhering to the surface to be cleaned is low, and the cleaning action part of the sponge body is easily deformed and deteriorated in a short period of time.
Therefore, conventionally, as shown in Patent Document 1, a block-like sponge body is wrapped with a synthetic fiber protective net sewn in a bag shape, and a peripheral portion of the protective net sewn in a bag shape and a peripheral portion of the sponge body A kitchen sponge made by sewing is proposed.
In the case of this kitchen sponge, when the object to be cleaned such as tableware is cleaned, the surface to be cleaned is cleaned by unevenness at the cleaning action site by the bag-like protective net while ensuring the cleaning liquid such as water from the sponge body oozes out. The dirt adhering to the surface can be scraped off smoothly, and deformation and deterioration of the sponge body can be suppressed by the bag-like protective net.

Japanese Utility Model Publication No. 6-46658

In the conventional kitchen sponge, the peripheral portion of the bag-shaped protective net and the peripheral portion of the sponge body are sewn, but in the majority of the cleaning action area other than the peripheral portion, the bag-shaped protective net and sponge The main body is in a state of being relatively movable in the surface direction and the thickness direction.
Therefore, when sliding cleaning operation is performed with the cleaning action part of the bag-shaped protective net applied to the surface to be cleaned, the cleaning action part of the bag-shaped protection net and the corresponding cleaning action of the sponge body The movement of the cleaning operation force is lost due to the movement in the surface direction with the part, and the state where the dirt scraping performance due to the unevenness of the protective net is not fully exhibited, and the cleaning operation that is experienced by the movement There is an inconvenience that the performance also decreases.
In addition, food residues etc. easily enter the gap between the cleaning action part of the bag-shaped protective net and the cleaning action part of the sponge body in the thickness direction, and the food residue etc. that has entered the bag Since it is held between the protective net and the sponge body in which the elastic restoring force is generated, it takes a lot of time to remove the food residue that has entered.
Furthermore, since it is necessary to sew the protective net in a bag shape while enclosing the sponge body, and to sew the peripheral part of the bag-like protective net and the peripheral part of the sponge body, This is inconvenient because it requires a lot of labor and increases the manufacturing cost.

  In view of this situation, the main problem of the present invention is to have both high cleanability and operability while suppressing deformation deterioration of the sponge body, and to facilitate the removal of food residues and the manufacture. The point is to provide a kitchen sponge that can be used.

  The first characteristic configuration of the kitchen sponge according to the present invention is that a protective net is attached to the outer surface of the sponge body.

According to the said structure, the sponge main body and the protective net located in the outer surface side are in the integrated state by which the relative movement in the surface direction and thickness direction was prevented by sticking of the said protective net.
Therefore, when sliding cleaning operation is performed with the cleaning action part of the protective net applied to an object to be cleaned such as tableware, between the cleaning action part of the protection net and the corresponding cleaning action part of the sponge body There is no movement in the surface direction, and the cleaning operation force can be efficiently transmitted to the cleaning portion of the protective net through the sponge body. Moreover, the cleaning operability can be improved by integrating the protective net and the sponge body.
Furthermore, there is no gap between the protective net cleaning action part and the sponge body cleaning action part in the thickness direction during the cleaning of the object to be cleaned. The food residue etc. which does not enter into the generated voids can be easily washed off the food residue attached to the outer surface of the kitchen sponge.
Therefore, the rational improvement of sticking a protective net on the outer surface of the sponge body can exert high cleaning function and high cleaning operability while suppressing deformation deterioration of the sponge body. It is possible to facilitate the removal of and to facilitate the manufacture.

In the second characteristic configuration of the kitchen sponge according to the present invention, the sponge body is configured in a block shape having a front surface, a back surface, and a peripheral side surface as the outer surface,
The protective net is in that it is attached to at least one of the front surface side and the back surface side of the sponge body.

  According to the above configuration, the protective net is attached to one of the front and back surfaces of the sponge body constituting the main cleaning action surface having a larger surface area than the side surfaces of each side constituting the peripheral side surface of the outer surface of the sponge body. By doing so, a higher cleaning function can be exhibited while suppressing deformation deterioration of the sponge body.

According to a third characteristic configuration of the present invention, the sponge body is configured in a block shape having a front surface, a back surface, and a peripheral side surface as the outer surface.
The said protection net | network exists in the point stuck on both the surface side of the said sponge main body, and the back surface side.

  According to the above configuration, the protective net is attached to each of the front and back surfaces of the sponge body constituting the main cleaning action surface having a larger surface area than the side surfaces of each side constituting the peripheral side surface of the outer surface of the sponge body. Thus, a higher cleaning function can be exhibited over a long period of time while further suppressing deterioration and deformation of the sponge body.

  A fourth characteristic configuration according to the present invention is that the protective net is not attached to the peripheral side surface of the sponge body.

According to the above configuration, the selection and use of protective nets attached to both the front and back sides of the sponge body allows the sponge body to maintain the function of suppressing deformation and deterioration of the sponge body and the high cleaning function over a long period of time. Since there is no protective net on the peripheral side surface of the main body, the cost can be reduced by reducing the number of manufacturing operations and manufacturing materials.
Furthermore, it is possible to avoid a decrease in deformation operation performance such as flexibility in the thickness direction (front and back direction) of the sponge body by sticking a protective net on the peripheral side surface side of the sponge body.

  A fifth characteristic configuration according to the present invention is that a nonwoven fabric is interposed between the protective net and the sponge body.

  According to the above configuration, at the time of cleaning an object to be cleaned such as tableware, the cleaning action part of the protective net reinforced with the nonwoven fabric while ensuring the exudation of the cleaning liquid such as water from the sponge body through the nonwoven fabric and the protective net. The dirt adhering to the surface to be cleaned can be efficiently and powerfully scraped off due to the unevenness at. Moreover, deformation and deterioration of the sponge body can be more effectively suppressed by the nonwoven fabric in addition to the protective net, and the surface of the nonwoven fabric on the protective net side can also be used as a decorative display surface such as a pattern.

  According to a sixth characteristic configuration of the present invention, the sponge net is configured such that the protective net is arranged in a direction in which the warp direction and the weft direction of the protective net intersect the side of the net sticking surface of the sponge main body. It is in the point stuck on the outer surface side.

  According to the above configuration, the characteristics of the protective net, that is, the warp direction and the weft direction are low in extensibility, and the warp direction and the direction intersecting the weft direction are high in extensibility. By setting the weft direction to the direction intersecting the side of the net attachment surface of the sponge body, the sponge body can be flexibly bent along the curved portion of the surface to be cleaned, and the cleaning operability can be further improved.
