Pasty Pesticide Applicator and Applying Method Thereof

Abstract

The present invention relates to a pasty pesticide applicator, comprising a cavity for containing pasty pesticide, an ointment base mounted inside the cavity and bonded together with pasty pesticide, and a screw for driving the ointment base to move along the inner wall of the cavity. One end of the screw is inserted into the inside of the cavity and the other end is outside the cavity and connected to a rotary handle. During application of pesticide, the operator removes the cap of the applicator from the cavity, rotates the rotary handle or the cavity to push the pasty pesticide in the applicator out of the cavity, holds the cavity in hand and directly smears the pasty pesticide on the target applying positions. The pesticide applying device provided by the present invention is characterized by safe use, simple structure, easy storage and portability.

Claims

1. A pasty pesticide applicator, comprising a cavity for containing pasty pesticide, an ointment base mounted inside the cavity and bonded together with pasty pesticide, and a screw for driving the ointment base to move along the inner wall of the cavity; one end of the screw being inserted into the inside of the cavity and the other end being outside the cavity and connected to a rotary handle.

2. The applicator according to claim 1, wherein the ointment base comprises a base plate and a sleeve inserted to the base plate and having internal thread; the screw passing through the sleeve and fitting with the internal thread of the sleeve to realize stretch-out and draw-back of the ointment base.

3. The applicator according to claim 1, wherein the applicator further comprises a cap, which covers an ointment discharge end of the cavity and may be sleeved on a rotary handle.

4. The applicator according to claim 1, wherein stripes are designed on the external surface of the cap to increase friction force.

5. A pesticide applying method of the pasty pesticide applicator of claim 1, including the following steps: removing the cap of the applicator from the cavity, rotating the rotary handle or the cavity, and driving the ointment base to move relatively along a screw inside the cavity and push pasty pesticide in the applicator out of the cavity; holding the cavity in hand and directly smearing pasty pesticide to the target applying positions; after application, reversely rotating the rotary handle or the cavity to take the pasty pesticide into the cavity.

6. The pesticide applying method according to claim 5 further comprising removing the cap and sleeving it onto the rotary handle to make for the rotation of the rotary handle.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0023] FIG. 1, FIG. 2 and FIG. 3 show a pasty pesticide applying device, comprising a cavity 1, an ointment base 2, a screw 3 and a cap 4. The cavity 1 is tubular and intended to contain pasty pesticide and comprises a first end and a second end. The first end of the cavity 1 is open. The pasty pesticide may stick out of cavity 1 from the first end. The ointment base 2 is mounted to the second end of the cavity 1. The ointment base 2 comprises a base plate 20 and a sleeve 21 inserted to the middle position of the base plate 20 and having internal thread. The screw 3 passes through the cavity 1 and the sleeve 21 from the second end of the cavity 1 and fits with the internal thread of the sleeve 21. The other end of the screw 3 is located outside the cavity 1 and connected to a rotary handle 30. By rotating the rotary handle 30, the ointment base may be moved from the second end of the cavity 1 to the first end or be drawn back from the first end of the cavity 1 to the second end, i.e.: stretch pasty pesticide out of the cavity 1 or draw it back into the cavity 1. As a preferred scheme, the screw 3 is inserted into the cavity 1 from the second end of the cavity 1 and extends till the second end of the cavity 1, or in other words, the length of the screw 3 is close to the length of cavity 1.

[0024] The cap 4 covers the first end of the cavity 1 and is intended to seal pasty pesticide in the cavity 1 to protect it from contamination. During application by the pesticide applying device, the cap 4 is pulled out from the first end of the cavity 1. The cap 4 is sleeved onto the rotary handle 30 to increase the contact area of the handheld location during rotation of the screw 3, making for rotation of the rotary handle 30 and preventing loss of the cap 4.

[0025] In this embodiment, the pesticide applying device further comprises a strut 5 mounted on the cavity wall of the second end of the cavity 1 in a fixed manner. The strut 5 is coaxial with the screw 3 and intended to support the screw 3.

[0026] As shown in FIGS. 4, 5, 6a and 6b, during use, the target object for application of pesticide is found at first, the applicator is taken out and the cap 4 of the applicator is removed from the cavity. The cap 4 may be sleeved onto the rotary handle 30 to increase the torque of the rotary handle 30 and friction force during rotation, thereby making for rotation of the rotary handle 30, then the rotary handle 30 or the cavity 1 is rotated to drive the ointment base to move relatively along the screw inside the cavity and push the pasty pesticide 10 out of the cavity 1 from the applicator;

[0027] The cavity 1 is held in hand, and the pasty pesticide 10 is directly smeared to the target applying position;

[0028] After application, the rotary handle 30 or the cavity 1 is rotated reversely to take the pasty pesticide 10 into the cavity 1.

[0029] The foregoing embodiments are only a few embodiments of the present invention. Their descriptions are concrete and detailed, but they shall not be therefore understood as limitations to the scope of the present invention patent. It shall be noted that for those skilled in the art, various changes and modifications may be made to the embodiments without departing from the spirit of the present invention, such as: combinations of different features of the embodiments. All these shall be in the protective scope of the present invention.
