Description

Spray Barrel {Barrel of Sprayer}

The present invention relates to a spray cylinder, and more particularly, to a spray cylinder which is improved in durability and easy to manufacture since the body is divided into a part having an injection hole and a press-in hole and a part having a pedestal, and fused and integrated. .

In general, the spray bottle manufactures a cylindrical body by blow molding, and attaches a separate flooring material to the lower end of the body to stabilize the bottom surface. That is, when the cylindrical body is formed by blow molding, traces obtained by cutting the bottom of the parison remain on the bottom of the body, and thus the flat surface is not formed, and therefore, it is not erected in place. In addition, when the tubular body is blow-molded by using a clogged tubular parison, the bottom surface is rounded off by the blow pressure and loss of stability is lost.

Therefore, as shown in FIG. 1, the conventional spray cylinder is integrated by tightly fixing a cylindrical bottom member 4 having a flat bottom in a lower part of the body 2 manufactured in a blow shape by using an adhesive or the like. do.

In the conventional spray cylinder made as described above, the adhesive portion 6 of the body 2 and the flooring material 4 is easily detached due to the low adhesive strength. That is, the adhesive part 6 bonded using an adhesive or the like changes the properties of the adhesive due to a change in temperature, inflow of chemicals (pesticides, etc.), and as a result, the adhesive force is lowered so that the body 2 and the flooring material 4 are reduced. When the flooring material 4 is separated from the body 2, the spraying is impossible because the flooring material 4 is not stably erected on the ground.

In addition, in the conventional spray bottle, the bottom of the body 2 formed by cutting off the bottom of the parison may be broken when the joint portion has a high pressure acting on the inside of the body 2. In other words, if the bottom of the parison is insufficiently bonded in the process of forming the body 2 by blow molding, if a high pressure is applied to the inside of the body 2, there is a fear that the pressure is easily broken.

An object of the present invention is to solve the above problems, the body is manufactured by injection molding divided into a part having a pedestal and a portion having an injection hole and indentation, etc., respectively by heating heating by installing a heating wire in the middle of the body divided into two It is to provide a spray cylinder excellent in pressure resistance and durability by integration by fusion.

Is connected to a power source (not shown), heated, and cut.

The injection hole 14 is for injecting a chemical such as pesticide into the second body 10, the stopper (not shown) is coupled. The inner circumferential surface of the injection hole 14 is formed with a female screw to which the stopper is coupled.

The press-fitting inlet 16 is installed and coupled to a bulanza (not shown) to which the hose is connected while applying pressure to the liquid stored in the first body 10.

Male threads are formed in the inlet 14 and the inlet 16.

The support protrusion 28 of the second body 20 is formed at a predetermined height so that the bottom surface is positioned at a predetermined distance from the ground to reduce the risk of damage or breakage.

It is possible to form a predetermined scale (not shown) on one side of the outer surface of the second body 20 so as to know the level of the medicine injected therein.

As shown in FIGS. 6 and 7, the first body 10 and the second body 20 form the insertion part 12 in the second body 20, and the fusion unit described above. It is possible to form 22 in the first body 10 described above.

The first body 10 may be provided with a discharge port 17 in addition to the injection port 14 and the indentation port 16 described above.

It is possible to protrude outwardly the support portion 21 in contact with the end surface of the insertion portion 12 in the position where the insertion portion 12 end of the fusion portion 22 is located.
