Description

[Detailed explanation of the idea] This case relates to a trigger set sprayer.

This type of atomizer is generally removably screwed onto the mouth and neck of a liquid container using a screw tube with the main body of the atomizer rotatably installed at the bottom of the device. Pull with your finger to get a spray.

However, if the above-mentioned screw tube becomes even a little loose, or if it becomes loose during use, the main body of the sprayer will rotate, making it difficult to operate the trigger, and the force will not be applied.

In consideration of this point, an upright part is provided protruding from the rear part of the body of the liquid container, and this is engaged with the rear part of the atomizer body, or a recess is formed in the rear part of the body of the liquid container, and the part of the atomizer body is connected to the upright part. A hanging piece is hung from the rear part, and it is held in the recess,
There are some products that solve the above problems, but with this type of product, the grip part becomes quite thick due to the raised parts and hanging pieces, and there are restrictions on the shape of the grip part, making it difficult to grip. There are drawbacks.

Furthermore, there is a drawback that the hanging piece of the upright part obstructs the rotation of the screw cylinder.

The present invention attempts to eliminate such conventional inconveniences and shortcomings.

The illustrated embodiment will be described below.

In the figure, 1 is a liquid container made of synthetic resin, and 11 is a liquid container made of synthetic resin.
The mouth and neck portion 12 is a thread formed on the outer periphery of the mouth and neck portion;
13 is the trunk, and 14 is the top surface of the mouth and neck.

2 is a synthetic resin sprayer main body, 21 is a screw tube rotatably attached to the lower part thereof, 22 is a screw thread formed on the inner periphery of the screw tube to be screwed into the screw thread 12, and 23 is a An outward flange 24 at the bottom of the sprayer body, the upper end of which is rotatably supported at the lower part of the sprayer body, and whose lower surface abuts against the top surface 13, is suspended from the bottom of the sprayer body within the spiral cylinder. This is a suction pipe that hangs down into the liquid container.

A fitting cylinder 25 that fits into the mouth and neck part 11 from the lower surface of the flange 23 is integrally provided, and the outer peripheral surface of the fitting cylinder 25 has a plurality of longitudinal protrusions with edges at the tips. The outer periphery of the lower end of the fitting tube 25 is tapered to facilitate fitting, and the inner edge of the mouth portion 11 is made to have a slightly larger diameter to facilitate fitting.

Incidentally, instead of the protrusions 26, vertical knurling portions may be provided to protrude.

According to the present invention, the fitting cylinder 25 that fits into the mouth and neck part 11 from the sprayer main body 2 is suspended, and a plurality of longitudinal protrusions 26 or knurling portions are provided on the outer peripheral surface of the hanging tube. When the fitting cylinder 25 is fitted into the mouth part 11, not only the fitting but also the pressurized jets of the protrusions 26, etc. act, and a large frictional effect against rotation acts, causing the screw cylinder 21 to Even if it is a little loose, or even if it becomes loose during use, the sprayer main body 2 will not rotate with the trigger operation, and the trigger operation will not be difficult or require force.

In addition, there is no need for an upright part from the liquid container or a hanging piece from the sprayer main body, and the upper part of the liquid container, that is, the gripping part, can be formed into a thin and arbitrary shape, making it easy to grip. There are no obstacles such as standing parts or hanging pieces.

Furthermore, a fitting tube 25 and a protrusion 26 are provided on the side of the sprayer main body 2.
. . , etc., the conventional liquid container 1 can also be used without any problem, which is convenient.

The structure and production are simple, and together with the fact that it can be provided at low cost, it is extremely useful in practice.
