  In this patent document 1, the structure is simple and can spray as much mist as possible on the spray target location and spray target object, and the spraying of excess mist is limited to areas other than the spray target location and spray target object. The effect of being able to be demonstrated.

  However, in the prior art disclosed in Patent Document 1, a part of the sprayed content liquid adheres to the inner peripheral surface of the hood and forms water droplets. There was a problem of dripping outside to wet the surroundings illegally or to get dirty.

  Accordingly, the present invention was devised to solve the above-described problems in the prior art, and technically prevents the content liquid adhering to the inner peripheral surface of the hood from forming water droplets from dropping from the hood. It is an object of the present invention to obtain an appropriate regulated spray of the content liquid without causing illegal wetting and contamination due to the dripping of the content liquid.

Among the present invention for solving the above technical problems, the means of the first invention is that the diameter is expanded in a trumpet shape from the base end opening part fitted to the nozzle head of the sprayer toward the front end opening part. The liquid absorbing member is provided at the tip opening.

In this first invention, the content liquid sprayed from the nozzle of the nozzle head of the sprayer is not scattered unnecessarily by the hood, and the spraying range is precisely regulated at the target location. Scatter.

During the spray operation of the content liquid, a part of the content liquid that adheres to the hood and forms water droplets collects into large water droplets and flows down the inner peripheral surface of the hood. The liquid content that has flowed down the inner peripheral surface of the hood flows toward the front end opening, but the front end opening is provided with a liquid absorbing member. It is absorbed by the absorbent member and does not drop out of the hood from the tip opening. Since the content liquid absorbed by the liquid absorbing member is appropriately evaporated from the liquid absorbing member, the hood can be reused.
Furthermore, in the first invention, since the liquid absorbing member is made of sponge or non-woven fabric, the hood can be formed of a resin sheet material, and the sponge or non-woven fabric can be provided on the hood.

Furthermore, in the first invention, a liquid absorbing member is provided on the entire periphery of the tip opening.

According to a second invention, in the first invention, a locking circumferential groove is provided on the outer peripheral surface of a cylindrical fitting jig that is externally fitted to the nozzle head, and a plurality of inner flange pieces are provided in the base end opening. The locking rib piece is inserted into and locked in the locking circumferential groove of the fitting jig to achieve assembly to the nozzle head.

In the second invention, the hood can be suitably assembled to the existing sprayer without difficulty. In particular, when the hood is formed by rounding the sheet material, the base end opening is circular, so that it is unsuitable for assembly with the nozzle head of the sprayer whose external shape is a triangular prism shape. By using the fitting jig in such a case, the assembly of the hood to the sprayer can be suitably achieved.

The third invention is the first or second invention, which is molded in a fan shape to expand the flaring cylindrical body, the one side edge of the body sheet, opened a plurality of engagement holes, the body sheet A plurality of engaging protrusions that fit into and engage with the engagement holes are provided at the other side end of the body, the main body sheet is rolled up, and the engagement protrusions are engaged with the engagement holes. Is added.

In this third invention, it is possible to provide the body sheet with an engagement hole and an engagement protrusion, and to obtain the hood at low cost and easily using thermoforming, etc. Attaching the hood to the body can be achieved easily and in a favorable state.

  Since the present invention has the above-described configuration, the following effects can be obtained.

In the first invention, the liquid content, without scattered unnecessarily around, while being-regulating precisely the intended position, can be sprayed.

In addition, even if the content liquid that adheres to the inner surface of the hood and drops into water droplets flows down the inner peripheral surface of the hood and flows toward the tip opening, it is absorbed by the liquid absorbing member and is removed from the hood. Therefore, the surrounding liquid is not wetted or soiled by the sprayed content liquid. Since the content liquid absorbed by the liquid absorbing member is appropriately evaporated from the liquid absorbing member, the hood can be reused.
Furthermore, the liquid absorbing member can be easily provided on the hood using a sponge or a non-woven fabric.

Furthermore, in the first invention, the content liquid can be absorbed by the tip opening regardless of the position of the hood, and the content liquid flowing down from the tip opening can be eliminated. As a result, it is possible to reliably prevent the surrounding liquid from being wetted and contaminated.

In the second invention, the hood can be suitably assembled to the existing sprayer without difficulty, so that it is possible to obtain an appropriate utilization without unreasonableness of the hood.

In the third invention, the hood can be obtained inexpensively and easily, and the attachment of the hood to the container body with the sprayer can be achieved easily and in a preferable state, and a preferable handling can be obtained. it can.
