Description

[Detailed description of the invention] Industrial field of application The invention relates to an applicator for applying chemical solutions such as detergents, cleaners, paints, insecticides, repellents, disinfectants, fragrances, glues, and anti-inflammatory analgesics. .

Conventional Technology A variety of structures have been proposed as applicators for chemical solutions such as cleaning agents. Strongly acidic or strongly alkaline liquids such as cleaners may be dangerous to the human body handling them, and paints may be difficult to remove from skin or clothing, and they may be difficult to remove when applied. In cases where the area is large, construction is difficult and workability is poor. Furthermore, when applying natural or synthetic resin brushes, brushes, non-woven fabrics, etc. to ceilings, walls, etc., the liquid often drips and stains the floor, workers' hands, clothes, etc. Moreover, it ran out of liquid quickly and had to be reapplied several times, making the work unhygienic and inefficient.

Problems to be Solved by the Invention The purpose of the present invention is to eliminate the problems found in the conventional applicator mentioned above and to provide a high-quality applicator with improved workability at a low cost.

Means for Solving the Problems That is, the present invention consists of a liquid extrusion container 1 having a support base 6 made of polyethylene on the upper part, and a liquid extrusion container 1 made of open-cell foamed polyethylene sponge, which is attached to the support base 6 by applying ultrasonic welding means. An application section 2 having a line-bonded part, and a liquid guide tube 3 having one end opening at the bottom of the container 1 and the other end penetrating the support base 6 and opening into the application section 2. The present invention relates to an applicator characterized in that the peripheral edge of the applicator 2 protrudes outward from the peripheral edge of the support base 6.

The applicator of the present invention has the above-described structure, and when the container 1 is gripped and pressed to deform in the state shown in FIG. 1, the pressure inside the container 1 increases, so that the liquid content 5 is It is supplied to the coating section 2 from the lower end opening 3a of the tube 3 through the inside thereof. In this way, by appropriately pressing and deforming the container 1 with the hand holding the container 1 and supplying the content liquid 5 to the applicator 2, the application work can be continued, and by appropriately adjusting the pressing deformation force, the content liquid 5 can be An appropriate amount can be continuously supplied to the application section 2 without dripping or splashing.
Application work can be performed efficiently and hygienically.

In the present invention, the container 1 may have any shape and structure as long as it can be pressed, deformed, released, and restored while the body is being held.For example, a transparent plastic container can be used to see through the inside and the contents can be seen through. This is suitable because the liquid level can be checked from the outside.

In the present invention, the applicator 2 connected to the upper end of the container 1 via the support 6 is made larger than the support 6. With this configuration, the applicator of the present invention not only improves the workability of coating when coating a wide area such as a flat surface, but also enables successful coating even in narrow areas such as the boundary between walls. Moreover, there is no fear that the support base will come into contact with the surface to be processed and damage it. On the other hand, application section 2
If this is smaller than or the same as the support base 6, it is inevitable that the support base 6 will come into contact with the surface to be treated and damage it during the coating operation.

The application section 2 has an open-cell foamed polyethylene sponge as its constituent member. Polyethylene sponge is stable against strong acids and strong alkalis, does not deteriorate or become brittle, and has excellent durability.

The thickness of the applicator 2 is appropriately determined depending on the type of chemical solution used and the application of the obtained applicator, and is not particularly limited. In such cases, it is appropriate to set it to approximately 5 mm to 50 mm.

The applicator 2 shown in FIG. 1 is fixed to the container 1 via a smaller support 6, but the support 6 may be molded integrally with the container. Although there is no risk of the support base 6 coming into contact with the object to be coated, its corners are rounded and the peripheral portion is relatively thin to provide elasticity, while the center portion is relatively thin to provide strength. You can also make it more targeted. The support base 6 is made of polyethylene, and is molded using, for example, an injection molding method. The thickness of the support base 6 is determined as appropriate in the same way as the coating part 2, but it is usually appropriate to set it to about 0.5 to 3 mm. The application part 2 and the support base 6 are bonded by applying ultrasonic welding means, and as a result, high adhesive strength can be obtained even though it is a bond between polyethylenes, which is difficult to apply adhesive, and cleaning liquid etc. The use of chemical solutions can eliminate the problem of peeling. Also, if the bonding is done by ultrasonic welding,
The continuous foam sponge that makes up the application section 2 melts at the bonded part with the support base 6, causing clogging. When communicating, communication becomes uncertain and there is a risk of producing defective products. In the present invention, clogging occurs in a linear manner by linear bonding, thereby substantially eliminating any adverse effects on the communication surface.

The attachment direction of the applicator 2 to the container 1 is horizontal in FIG. 1, but it is not limited to this horizontal type, and may be an inclined type as shown in FIG. 2, or a vertical type. In particular, the inclined type is preferable in terms of coating workability.

In FIG. 1, a tube 3 is used as a liquid guide means for supplying the medicinal solution in the container 1 to the applicator 2, and the tube 3 and the weight 4 provided in the lower end opening 3a are used to hold the applicator of the present invention upright. use, inverted use,
Although the content liquid 5 can be stably supplied to the application section 2 regardless of the orientation of the container 1 such as when used horizontally,
Thus, according to the applicator of the present invention, paints, cleaning agents,
Chemical liquids such as shoe cleaners, carpet cleaners, glues, anti-inflammatory analgesics, repellents, bactericides, insecticides, and repellents can be applied to objects to be treated with good coating work. In particular, when using the applicator of the present invention as a cleaning agent applicator to clean a bathroom, etc., it is difficult to reach areas such as the boundary line between the bathtub and the floor, or the boundary line or boundary point between the wall and other areas that are difficult to reach with a normal sponge. It has the advantage of being able to clean even border areas very well, and is extremely effective for cleaning small areas such as bathrooms, washrooms, kitchens, sinks, sinks, and gas ranges. Furthermore, the application part and its support base, which come into direct contact with cleaning fluids and other chemicals, are both made of polyethylene, which has good chemical resistance, so they have excellent durability, and they are bonded using ultrasonic welding, so they are strong Despite being made of polyethylene, which can be bonded, has low material cost, and is easy to mold, there is no risk of the applied part peeling off from the support base, and a high-quality product can be provided at a low cost.
