The present invention is a foam generating attachment that is used by being attached to the outside of a discharge port such as a normal pump container or an aerosol container containing various liquid contents.

In other words, it is an externally attached cylindrical member, and the liquid content flowing in from the discharge port of the pump container or the like to which it is attached is made into a foam by passing it through a mesh inside the cylindrical shape and then external space. It is equipped with a function to release.

Examples of liquid contents to be applied include soaps, disinfectants, cosmetics, emulsions, shaving foams, hair styling foams, detergents, hair dyes, shampoos, rinses, and insecticides as described below.

In the present specification, the term “container” is used to include not only the container body in which the liquid contents are stored but also the entire structure from the container body to the nozzle, and the outlet of the foam generating attachment. The side (left side in FIG. 1 and the like) is referred to as “front”, and the opposite nozzle side (right side in FIG. 1 and the like) is referred to as “rear”.

For example, Patent Document 1 below discloses a discharge mechanism having a function of generating bubbles of liquid contents contained in a pump container or the like.

In the discharge mechanism of Patent Document 1, a concave portion is provided at the tip (discharge port) of an ejection nozzle for container contents (nasal spray), and a cylindrical nozzle tip for foam generation is attached to the concave portion together with a mesh member. It is a thing.

As described above, the conventional liquid content discharge mechanism having a bubble generation function is formed by forming a recess at the tip discharge port of the nozzle itself, and a cylinder corresponding to the bubble generation mesh member and its downstream member. So-called nozzle tip is incorporated.

That is, a cylindrical nozzle tip for foam generation is provided in an internal space region that constitutes a part of the nozzle tip side portion as an output side discharge passage for the liquid content.

Therefore, the size of the nozzle tip in the longitudinal direction and the radial direction is naturally limited by the size range of the internal space region of the nozzle, and the nozzle tip having a size that exhibits a sufficient bubble generating action of the liquid content is provided. It was difficult to use.

Also, it was difficult to improve the efficiency of the entire nozzle assembly work because a small-sized nozzle tip or mesh member had to be incorporated in the narrow internal space area at the nozzle tip side.

Therefore, in the present invention, a foam generation attachment comprising a cylindrical portion externally attached to the discharge port of the liquid content is provided, and the size restriction at the time of creating the foam generation member is eliminated, The object is to simplify the operation of attaching the generating member to the nozzle side.

Also, the purpose is to achieve foam release in various liquid content release mechanisms that do not have the foam generation function of pump containers and aerosol containers.

The present invention solves the above problems as follows.

The present invention is directed to a foam generation attachment for a container content having the above-described configuration, and a pump-type product and an aerosol-type product provided with the foam generation attachment.

In this way, the present invention uses the foam generating attachment consisting of a cylindrical portion that is externally attached to the discharge port of the liquid content, thus eliminating the size restriction when creating the foam generating member. Further, it is possible to further simplify the operation of attaching the foam generating member itself.

By this pumping action, the liquid content stored in the storage space area between the suction valve and the discharge valve becomes “content passage 2a—first space area 3a—groove 4b—second space area 4c”. -Flows through the hole 4a "into the internal space of the foam generating attachment 5 in a fog state.

The liquid content that has flowed into the foam generating attachment 5 passes through the rear mesh 5e, and further passes through the front mesh 5f before being discharged into the external space.

Upon release to the external space, the liquid content is agitated by hitting the rear mesh 5e, the front mesh 5f, and the inner peripheral surface of the foam generating attachment 5, and is in a state of being finely divided. It changes into a foam-like content that contains.

Outside air is sucked from the slit 5d and taken into the attachment in a form corresponding to the air content used for the generation of the foamed contents, or in a form corresponding to the flow of the liquid contents flowing into the foam generating attachment 5. It is.

As the rear mesh 5e and the front mesh 5f incorporated in the foam generating attachment 5, the lattice mesh 11, the honeycomb mesh 12, the circular mesh 13 and the target mesh 14 shown in FIG. 3 are used. The same applies to each mesh in each of the foam generating attachments 5 ′, 5 ″ and 6.

When the rotation operation of the trigger lever 1 is stopped, the piston 2 moves upward by the action of a coil spring (not shown) of a known pump mechanism. The trigger lever 1 rotates in the clockwise direction in the figure by a cam action with the cylindrical portion 2b as the piston 2 moves, and returns to the stationary mode in FIG.

Of course, the present invention is not limited to the above-described embodiment. For example, as a component for stirring the liquid contents into a foam state, the foam is formed on the inner peripheral surface of the foam generation attachment. An uneven portion and a rib-shaped portion that are made are also used.

Further, the number of the air generating slits 5d of the

foam generating attachments

5, 5 ', 5 "and the number of the air intake hole portions 6b of the foam generating attachment 6 are arbitrary.
