Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container, which is attached to the mouth of a container, sucks the liquid in the container into the cylinder by the reciprocating movement of a piston which is interlocked with the movement of a push button, pressurizes it, and flows out from an outlet. And a thumb-operated push-type manual dispenser for lowering the nozzle head with the thumb.

2. Description of the Related Art Due to the problem of depletion of the ozone layer by chlorofluorocarbon gas, a manual dispenser that pressurizes and discharges liquid by a pump operation using a piston without the use of chlorofluorocarbon gas is drawing attention. This type of manual dispenser is roughly classified into a trigger type and a push type (also referred to as finger type).

In both the trigger type and push type manual dispensers, the dispenser body is attached to the mouth of the container, and the reciprocating motion of the piston sucks and pressurizes the liquid from the container into the cylinder to let it flow out. Match and differ only in the operation that causes the piston to reciprocate.

In a trigger-type manual dispenser, as shown in FIG. 16, in the palm of the dispenser body, the dispenser body is placed on both sides of the thumb and other fingers (for example, the index finger,
It is pinched by the middle finger). When the trigger-111 is pulled by the index finger and the middle finger, the piston reciprocates in the cylinder in conjunction with the trigger. An orifice communicating with the cylinder via the secondary valve is formed at the tip of the nozzle cap,
Pressurized liquid flows out from this orifice.

In the push type manual dispenser, as shown in FIG. 17, four fingers other than the index finger are entangled so that the entire palm is brought into close contact with the container from the dispenser body to the container. Then, the push button (also called the head) at the tip of the piston is pushed in with the index finger to lower the piston.

The beak 117 is formed integrally with the push button 620, and the pressurized liquid flows through the outflow passage inside the beak, passes through the secondary valve,
It flows out from the orifice at the tip of the outflow passage.

In the small push type manual dispenser, as can be seen from FIGS. 18 (A) and 18 (B), the beak is omitted, and the pressurized liquid flows out from the orifice 731 of the nozzle 730 embedded in the push button 720. To be done.

According to the trigger-type and push-type manual dispensers having such a configuration, the pressurization is performed by pulling the trigger (in the case of the trigger-type) or pushing the push button without using CFC gas. The liquid is atomized and discharged.

If a foaming means such as a net or sponge is arranged in front of the orifice, the pressurized liquid can be foamed and flowed out.

[0010]

DISCLOSURE OF THE INVENTION Dispensers using chlorofluorocarbon gas for pressurization (eazol type dispenser)
Said), if the nozzle is pressed continuously, the pressurized liquid continuously flows out, and a large amount of the pressurized liquid can be easily obtained.

On the other hand, in the manual dispenser, a large amount of liquid cannot flow out unless the pulling operation of the trigger (in the case of the trigger type) or the pushing operation of the push button is repeated.

The outflow amount (unit outflow amount) of the liquid in one stroke in the manual dispenser is a value (SA) obtained by multiplying the stroke (S) of the piston by the inner area (A) of the slinder. The lengths of the piston and cylinder are limited due to the design, and it is difficult to increase the stroke. Compared to the stroke, the increase in the inner area of the cylinder is not so difficult in terms of design. However, if the inner area of the cylinder is increased, it is necessary to apply a large pushing force to the piston.

Aerosol type, trigger type manual type,
In any push-type manual dispenser, the nozzle head (azole type) is pushed in, the push button (push type manual type) is pushed in,
Trigger pulling (trigger-type manual operation) is performed with the index finger. However, since the index finger is not so strong, a large pushing force and traction force cannot be obtained. Also,
Poor operability due to a small degree of freedom in twisting the index finger and a narrow operating range.

In particular, in the push type manual dispenser, as can be easily understood from the experience, the index finger for pushing the push button is not suitable for pushing with a large pushing force. Therefore, the inner area of the cylinder cannot be set large, and a large unit outflow amount cannot be secured.

Recently, thumb operated aerosol dispensers have been provided. For example, the actual public Sho 62
As disclosed in Japanese Patent Publication No. 042776, in this type of dispenser, a plastic handle is fitted in a metal container, and the valve stem can be pushed by a lever lever. When a finger other than the thumb is locked to the handle and the container is lifted and the tip of the lever lever is pushed with the thumb, the valve stem descends and the liquid flows out.

The thumb-operated freon gas type dispenser has an advantage that a large pushing force is originally generated by pushing with the thumb and the pushing force is increased by the principle of leverage. Also, good operability can be obtained.

As described above, when the thumb is operated, a large pushing force and good operability can be secured, but a thumb-operated manual dispenser is not known.

An object of the present invention is to provide a combination of a container for storing a liquid and a thumb-operated push type manual dispenser.

[0019]

In order to achieve this object, according to one embodiment of the present invention, a container is formed in a shape that can be held by a finger other than a thumb, and a finger for holding the container is engaged. A flange is formed on the cylinder to prevent it from slipping upward. The rotation of the push button is prevented by the rotation preventing means, and the cylinder is attached to the container opening so that the flange is in substantially the same direction as the orifice of the push button.
