Abstract

PROBLEM TO BE SOLVED: To obtain a squeeze type spray container which can produce a foamed substance from liquid content and air and instantaneously spray it to a distance and over a wide area when the container is squeezed, by specifying the volumetric mixing ratio of liquid to air of the foamed substance and the diameter of a nozzle. SOLUTION: When the body of a container main body of a squeeze type spray container 1 is squeezed, a liquid content and air in the container main body are respectively led to a liquid-gas mixing chamber 13 through a liquid inlet path 11 and an air inlet path 12 of a foamed substance sprayer 10. As a result, a foamed substance is produced through a net element 14 and sprayed outside from a spray nozzle 16 through a delivery path 15. The volumetric gas-liquid mixing ratio of the foamed substance [volume of foamed substance/(weight of foamed substance/density of foamed substance)] is specified within a range of 2-12. The diameter of spray nozzle is specified within a range of 0.3-3.0mm. Thereby the foamed substance is instantaneously sprayed to a distance and over a wide area.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a squeeze-type discharge container for squeezing a container body to form a foam from a liquid content and air in the container body and discharging the foam to the outside. The present invention relates to a squeeze-type discharge container capable of instantly spraying foam on a large area.

[0002]

2. Description of the Related Art As is well known, in a discharge container for discharging a liquid material as a foam, the liquid material and air inside the container body are squeezed by squeezing the body of the container. There are many types of discharge containers such as a squeeze-type discharge container that mixes and discharges a foam through a mesh.

The squeeze-type discharge container is used as a discharge container for discharging shampoo, rinse, face wash foam or the like as a foam.

In the conventional squeeze type discharge container, it is difficult to spread the discharged foamy material to a long distance, and
It was impossible to continuously discharge foam during use. Therefore, it is not suitable to be used for the purpose of spraying a bath cleaning agent or the like as a foam on a relatively large area such as a vertical wall surface of a bath.

Therefore, an object of the present invention is to provide a squeeze type discharge container capable of spraying foams to a long distance and instantaneously spraying foams over a wide area. .

[0006]

As a result of intensive studies, the inventors of the present invention have found that the gas-liquid mixing volume ratio [volume of foam / (weight of foam / density of liquid content)] and discharge port It has been found that a squeeze type discharge container having a diameter within a specific range achieves the above object.

The present invention comprises a container body for containing a liquid content and a foam discharge device attached to the mouth of the container body, wherein the foam discharge device comprises a liquid introducing passage and an air passage. An inlet passage, a gas-liquid mixing portion, a discharge flow passage, and a discharge port, and the liquid content and air inside the main body are squeezed by squeezing the body of the container main body with the discharge port facing downward. A squeeze-type discharge container for introducing foams from the liquid introduction path and the air introduction path into the gas-liquid mixing section to form foams, and discharging the foams from the discharge port to the outside through the discharge flow path. Therefore, the gas-liquid mixing volume ratio of the above foam [volume of foam / (weight of foam / density of liquid content)] is 2 to 12.
The above object is achieved by providing a squeeze-type discharge container characterized in that the discharge port has a diameter of 0.3 to 3.0 mm. The above gas-liquid mixing volume ratio [volume of foam /
(Weight of foam / density of liquid content)] is hereinafter referred to as “gas-liquid mixing ratio”.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the squeeze type discharge container of the present invention will be specifically described below with reference to the accompanying drawings.

FIG. 1 shows a squeeze type discharge container according to the present invention. FIG. 1 (a) is a view of the squeeze-type discharge container of the present invention seen from above, and FIG. 1 (b) is an enlarged cross-sectional view of a main part of the squeeze-type discharge container of the present invention. As shown in FIG. 1 (b), the squeeze-type discharge container of the present embodiment is a container body (not shown) for containing a liquid content, and a foam-like substance discharge device attached to the mouth portion 2 of the container body. It comprises a device 10. The foam discharge device 10 includes a liquid introduction path 11 and
Air introduction path 12, gas-liquid mixing section 13, and discharge flow path 15
And a discharge port 16, and by squeezing the body portion (not shown) of the container body, the liquid contents and the air inside the container body are respectively introduced into the liquid introduction passage 11
Further, the air is introduced from the air introduction path 12 into the gas-liquid mixing section 13, the foam is formed through the mesh body 14, and the foam is discharged from the discharge port 16 to the outside through the discharge flow path 15. Has become. Further, the foam discharge device 10 is formed so that the gas-liquid mixing ratio of the foam is 2 to 12, and the diameter of the discharge port 6 is 0.3 to 3.
It is 0 mm. The foam discharge device 10 attached to the mouth portion 2 of the squeeze-type discharge container shown in FIGS. 1A and 1B has four discharge ports.

Further, in the squeeze type discharge container of the present invention, the gas-liquid mixing ratio is set to 2 by forming the liquid introducing passage 11 and the air introducing passage 12 so as to have a proper cross sectional area. It is formed so that it becomes ~ 12. In addition,
The preferred gas-liquid mixing ratio is 8-12.

When the gas-liquid mixing ratio exceeds 12, when the body of the container body is squeezed and a foam is discharged, a large amount of air is mixed and the container body is often dented. It takes a long time for air to enter, continuous discharge cannot be performed for a long time, and since the proportion of air is high, it is not possible to spray foams to a long distance. When the gas-liquid mixing ratio is less than 2, bubbles are less noticeable, it is difficult to confirm the liquid on the adhering surface, and the liquid drips immediately. Further, since the sound of gas-liquid mixing is hardly generated when discharging the foam, there is no feeling of discharge.

In order to form the gas-liquid mixing ratio within the above range in the squeeze type discharge container of the present invention,
The ratio (a / b) of the cross-sectional area a of the liquid introduction passage 11 and the cross-sectional area b of the air introduction passage 12 is 1/1 to 1/6, preferably 1
It is formed so that it becomes / 2-1 / 4.

In the present invention, the gas-liquid mixing ratio means the value measured as follows. That is, 100 m of foam discharged from the squeeze discharge container of the present invention into a beaker.
1 is added, the weight of the foam is measured, and the gas-liquid mixing ratio is determined by the following formula. Gas-liquid mixing ratio = 100 (ml) / [(weight of foam 100 ml (g) / density of liquid content (g / ml)]]

Further, in the squeeze type discharge container of the present invention, the diameter of the discharge port is 0.1 to 3.0 mm,
It is preferably 0.5 to 2.0 mm. When the diameter of the discharge port exceeds 3.0 mm, continuous discharge cannot be performed for a long time, and foam cannot be sprayed to a long distance. 0.1
If it is less than mm, the liquid material is less likely to form bubbles, and the discharge amount is too small. Also, the squeeze pressure becomes too high.

Further, although the squeeze type discharge container in the above embodiment has four discharge ports, the number of the discharge ports is not particularly limited and may be any number. In the squeeze-type discharge container of the present invention, in order to eliminate coalescence of the foam, and to fly the foam over a wide range and far,
It is preferable to have 1 to 5 ejection ports.

Examples of the liquid contents contained in the container body of the squeeze-type discharge container of the present invention include bath cleaners, toilet cleaners, floor cleaners and car cleaners.
