Description

Detailed Description of the Invention (Industrial Application Field) The present invention is an apparatus that has the function of squeezing the body of a soft plastic container to release a surface-active content liquid in the form of a foam when the container is used facing downward. Regarding.

(Prior Art) An example of a conventional instrument is shown in Figure 5. In the figure, 16 is an air pipe constituting a flow path 18 for air 2, 17 is a soft bottle containing content liquid 1 with high surface activity, and 2
Reference numeral 0 denotes a mixer for liquid 1 and air 2, in which liquid 1 entering from the liquid flow path 19 is combined with air 2 at the lower end of the air pipe 16, and the liquid 1 enters the mixer 2.
The liquid 1 and the air 2 are mixed inside the container 2, and after being regulated by the net 21, they are released as foam 3 from the tip of the inner stopper 22.

The cap 23 prevents the foam 3 from being released when not in use.

Since the conventional device is constructed as described above, it has the function of squeezing the body of the bottle 17 to mix the content liquid 1 with high surface activity with air 2 and release it as foam 3. Since the squeezing force is done by hand, it is not constant, the output of the foam 3 is not stable, it takes time to suck in the air that is continuously ejected, the air pipe 16 becomes loose, and the mixture between the liquid 1 and the air 2 is The workability is poor because the ratio changes, and the structure is complicated and the equipment is expensive.

(Problems to be Solved by the Invention) From the above-mentioned background, the structure and assembly are simple without using the air pipe 16, and when used facing downward, the generation of bubbles is stable and the bubble jetting operation is achieved. The purpose of the present invention is to provide a foam generating device that can be used easily.

(Means for solving the problem) The present invention generates foam 3 through a foam generator 11 installed in the mouth 12 by squeezing the soft plastic container 5 with the outlet 13 facing downward. A device that can be used within the cap mechanism 12 or
and the soft plastic container 5 to seal the container 5 and place the foam 3
an inner stopper 6 equipped with a mixing chamber 9 having the function of generating
A foam generating device comprising a net or foam 11 for homogenizing the foam 3 between the cap 12 and the inner stopper 6, and connecting the mixing chamber 9 of the inner stopper 6 and a soft thin-walled inner container 4. The inner container 4 contains the liquid content l, is connected to the mixing chamber 9, and has at least one air hole 8 through the inner stopper 6 that communicates the inside of the mixing chamber 9 of the inner stopper 6 with the inside of the bottle 5. is provided on the side wall of the soft plastic container 5 to allow air 2 to flow in from inside the soft plastic container 5 outside the medium container 4, so that the content liquid 1 and the air 2 are separated within the container 5, and the air pipe 16 is This is a foam generating device that is intended to be used facing downward, and is characterized by the fact that it is not necessary.

(Function) When the conventional bottle 17 is used facing downward to generate bubbles, the air 2 is sent through the air pipe 16.
Inside and bottle] The inside of 7 is filled with bubbles 3, and the ratio of air 2 and liquid 1 becomes out of order.

In addition, there is resistance to returning the inside of the bottle 17 to its original state by sucking in the air 2, and it takes time to restore the interior to its original state. Further, if the air pipe 16 is open, the state of the bubbles 3 will change if the liquid 1 enters the air pipe 16, and if a bag is attached to the rear of the air pipe 16, it will become complicated and expensive.

In the present invention, first, in order to simplify the structure, the air pipe 16
Instead, we decided to introduce air between the very simple thin-walled inner container 4 and the soft squeeze bottle 5.

Therefore, the method of taking the liquid 1 and air 2 is completely different from the conventional mechanism, and therefore, it is possible to separate the liquid 1 and air 2 within the bottle 5, and the state of the foam 3 can be stabilized.

Since the medium container 4 is used, when the liquid 1 becomes empty, it can be used again simply by refilling with a new medium container 4.

Further, since the squeeze bottle 5 is oriented downward, if the content liquid 1 is likely to drip due to its own weight before any force is applied to the squeeze bottle 5, the pulp mechanism 10 can be provided to prevent the liquid from dripping.

Therefore, if the present invention is carried out, when the foam 3 is generated by downward use, the foam can be produced stably, and a squeezing foam producing device that can be used in a wide range of applications becomes possible.

Furthermore, since there is no air pipe 16, the liquid 1 can be used without any problems even when gas is likely to be generated.

(Example 1) Figure 1 is a cutaway side view showing one example of carrying out the present invention.

In the figure, 5 is a soft cylindrical bottle made of low-density polyethylene, which is placed downward as shown in the figure.
A screw is carved on the outside of the bottom opening. 4 is made of extremely thin low-density polyethylene and fills the bottle 5 with air 2.
The inner container is also placed facing downward, and contains a liquid 1 having high surface activity. Reference numeral 6 denotes an inner stopper made of rigid low-density polyethylene, which has a shallow bowl shape, and the upper end of the peripheral wall engages with the outer periphery of the lower end of the bottle 5 to support it, and the central part is tower-shaped and has a soil part. The opening supports the lower end opening of the middle container 4, and at least one air hole 8 is bored in the middle peripheral wall to allow the air 2 in the bottle 5 to flow in, and the liquid content 1 in the middle container 4 to flow down from the upper opening. A mixing chamber 9 is formed in which the mixture is mixed. 12 is a cap at the lower end, and the bowl-shaped main body is made of net or foam material on one side and holds the inner stopper 6.
Bottle 5
The lower part is shaped like a tube and forms a discharge port for the foam 3.

When the bottle 5 is grasped and squeezed, the air 2 inside flows from the air hole 8 into the mixing chamber 9 of the inner stopper 6, and at the same time, the built-in medium evaporator 4 is also squeezed, and the liquid inside flows into the lower part. As it flows into the mixing chamber 9 of the inner stopper 6 from the opening, the content liquid 1 and air 2 collide and mix in the mixing chamber 9, generating bubbles 3, which are homogenized by the net or foam 11 at the bottom. , is discharged from the discharge port 13 at the lower end of the cap 12.

Next, Figure 2 illustrates a convenient method for attaching the inner container 4 to the head of the inner stopper 6. That is, as shown in the same figure (al),
An aluminum foil 14 laminated with plastic is pasted to the lower end opening of the inner container 4 to seal it, while as shown in the same figure (bl),
If the breaking nozzle 15 with a sharp upper end is set in the head opening of the inner stopper 6 and the lower end of the inner container 4 with the aluminum foil 14 affixed thereto is inserted, the sealing aluminum foil I4 will be inserted into the breaking nozzle 15. The fitting of the middle container 4 into the inner stopper 6 is completed at the same time as it is broken at the sharp upper end. With this configuration, go inside bottle 5.
'After attaching the inner container 4, I tried squeezing the bottle 5, but no problems were found and good results were obtained.

(Example 2) Figure 3 is a cutaway side view showing another example of implementing the present invention.

This example is characterized by the provision of a valve mechanism lO that lightly closes the inlet of the liquid content 1 of the inner container 4 into the mixing chamber 9 at the upper end of the inner stopper 6, and other aspects are the same as in the first embodiment. .
□ That is, since the present invention is configured to generate bubbles downward, both the bottle 5 and the inner container 4 are assembled and stored with the opening facing upward. In addition, this configuration was devised to be applied when such a phenomenon is considered to be undesirable, in which the liquid content l sometimes drips from the inner container 4 due to its own weight even though it is not squeezed.

Therefore, in this example, even if the device is reversed and the opening is directed downward, the valve mechanism 10 lightly suppresses the inflow of the liquid content 1 into the mixing chamber 9 of the inner stopper 6, so that the liquid content 1 The liquid does not push open the valve mechanism 10 due to its own weight and does not flow into the mixing chamber 9, so that the liquid content does not drip from the discharge port 13. However, when the bottle 5 is squeezed, the inner container 4 is also squeezed, and the liquid content 1 is compressed and generates pressure 5, which pushes open the valve mechanism 10 and flows back into the mixing chamber 9. The mixing with air 2 in this process is rather accelerated and produces foam 3 of good quality. In this case, the content liquid 1 has a high surface activity, a relatively low viscosity, and a preferable foam state can be obtained when the liquid is 50 centivoise or less.

(Example 3) Figure 4 shows a cutting diagram showing yet another example of implementing the present invention. FIG.

In this example, the center lower end of the inner stopper 6 protrudes in a spherical shape, and is configured to block the upper end of the lower center outlet 13 of the cap 12 to block the flow path of the bubbles 3. 12 is provided with a screw that engages with the lower outer wall of the bottle 5 on the inner wall of the upper bowl-shaped part, and the cap 1 is attached by placing a hand on the outer wall of the bowl-shaped part.
The upper end opening of the discharge port 13 can be opened and closed by rotating the discharge port 2 and raising and lowering the discharge port 13.

That is, in this example, the foam 3 generated in the mixing chamber 9 of the inner stopper 6 is transferred to the discharge port 3.
This has the effect of being able to control the amount discharged.

The rest is the same as in Example 1.

(Effects of the invention) In conventional instruments that use pipes, when squeezing is repeated to continuously generate bubbles, the voids and air holes are filled with bubbles and the ratio of liquid and air changes. . In addition, if the pipe is made of a material that generates gas in the liquid, the opening time may cause the pipe to erupt.

In the present invention, since the liquid and air are separated in the container, the ratio of liquid and air is constant, and a constant amount of bubbles can be produced from the beginning to the end of use. When only the gas is released, the liquid content will not spill out.

The present invention has a simple structure and can produce consistent foam.

Practical tests were carried out by carrying out the present invention by storing mold cleaner, microwave cleaner, glass cleaner, etc. in the inner container 4 as the liquid content 1, and good results were obtained even when the container did not fall over.
