とに成功したもので、以下、図示の実施例により
この考案を説明する。 In recent years, in the development of aerosol injection means for liquid foods such as liquid seasonings, from the viewpoint of food hygiene in particular, injection containers with an injection port that is normally closed and opened only during injection operation have been developed. It has started to be proposed. The "closed injection port type aerosol button" disclosed in Japanese Utility Model Application Publication No. 143007/1987 is an example of the above-mentioned proposal and was invented by the inventor of the present invention. However, in such conventional proposals, in cases where the injection valve is housed within the container body, such as a normal aerosol injection container, the distance from the injection valve to the injection port is long, so the injection valve is Even when the injection port is opened, sufficient injection pressure is not immediately applied to the liquid present inside the injection port, resulting in poor injection conditions at the initial stage of injection, which often results in liquid dripping or dripping. There is a very small amount of liquid remaining in the injection passage after the injection valve and injection port close due to the completion of the injection operation, and the liquid pressure of the remaining liquid decreases over time and the injection performance is lost. It is. This idea is
Having succeeded in eliminating the drawbacks of this kind associated with previous proposals, the invention will now be explained by means of the illustrated embodiment.

てしまう。(Constitution of the invention) In other words, 2 is the button body, valve stem 1
The crown is fixed to the. The valve stem 1 is used to open an injection valve in a container body (not shown) by being lowered, as in the case of an ordinary aerosol injection container, and an injection passage 11 is bored therein. A horizontal hole 21 is bored in the button body 2, and a sealing O-ring 22 is inserted into the inner part of the horizontal hole 21. Reference numeral 3 denotes a nozzle cylinder having an injection port 32 bored in an end wall 31. This nozzle cylinder 3 is fitted into a horizontal hole 21, and the inside of the nozzle cylinder 3 is connected to the injection passage 11 of the valve stem 1 described above.
It is connected to the. Reference numeral 4 denotes a valve rod having a stopper 41 at its tip that can fit into the injection port 32, and is loosely inserted into the nozzle tube 3, and this valve rod 4 is supported pivotally on the button body 2 via a sealing O-ring 22. ing. The valve stem 4 is horizontally supported horizontally by a coil spring 5, and the coil spring 5 has stronger elasticity than the above-mentioned injection valve. Next, 6 is a key-shaped spring lever, and a fulcrum for the key portion 63 is provided at the rear of the top of the button body 2. Spring lever 6
The lateral limb 61 has an elasticity comparable to that of the coil spring 5, and is floating above the top surface of the button body 2. The end of the vertical limb 62 of the spring lever 6 is anchored to the tail 42 of the valve stem 4. Here, "elasticity comparable to the coil spring 5" refers to an elasticity that is almost the same as that of the coil spring 5. If it is too weak, the injection port 32 will not open even if the side limb 61 is pressed, and if it is too strong, the pressure At the same time, the injection port opens.

る。 According to the illustrated example, the rear wall 23 of the button body 2
A through hole 24 for inserting the valve stem 4 is bored in the
If the tail portion 42 of the valve stem 4 is designed to be short as shown by the imaginary line, the through hole 24 is not necessary. 25 is a washer for four valve stems. In the illustrated example, the length of the nozzle tube 3 is designed to be considerably longer than the depth of the horizontal hole 21, so the front part of the nozzle tube 3 protrudes from the button body 2, and the aim of the injection is good during operation. It is considered to be.

ル筒３内はここでも外気から隔離されている。 This device is constructed as described above, and since the valve stem 4 having the plug 41 at its tip is elastically supported forward by the coil spring 5, in the non-operating state shown in FIG. The injection port 32 is closed,
Therefore, in normal times, the liquid filling the inner passage of the injection port 32 is completely shielded from the outside air, so that the liquid is always kept in a clean state.
Note that the valve stem 4 is pivotally supported by the button body 2 via a sealing O-ring 22 inserted deep into the side hole 21, so the inside of the nozzle cylinder 3 connected to the injection passage 11 is here. But it is isolated from the outside air.

レやポタ落ちが発生しない。 For the injection operation, the fingertip 7 is placed on the side leg 61 of the spring lever 6 and pressed, as shown in FIG. As mentioned above, the spring lever 6 is in the shape of a hook as shown in the figure, and the fulcrum for the key part 63 is provided at the rear of the top of the button body 2, and the lateral limb 61 is floating above the top surface of the button body 2. The end of the longitudinal limb 62 engages the tail of the valve stem 4. Therefore, lateral limb 6
1 is pressed by the fingertip 7, the end of the lateral limb 61 gradually sinks, and the valve stem 4 corresponds to the amount of the sinking.
The stress applied to the pull-out direction (to the right in the figure) gradually increases. By the way, as mentioned above, the elasticity of the lateral limb 61 is caused by the coil spring 5 elastically supporting the valve stem 4.
In addition, since the valve stem 4 receives the frictional force with the sealing O-ring 22 and the frictional force between the end wall 31 of the nozzle cylinder and the plug body 41 at the injection port 32, the fingertip 7 The injection port 32 remains closed until the pressing force overcomes the sum of the elasticity of the coil spring 5 and the frictional force described above. Next, lateral limb 6
1 is floated above the top surface of the button body 2 as described above, but if the lateral limbs 61 continue to be pressed, part of the lower surface of the lateral limbs 61 will come into contact with the top surface of the button body 2. If the button body continues to be pressed further, the button body begins to descend, the injection valve in the container opens, the pressurized liquid rises through the valve stem 1, and the liquid pressure in the nozzle cylinder 3 increases. The injection valve is fully opened at the bottom dead center of the stroke of the valve stem 1, and the lowering of the button body 2 is also stopped. Therefore, if the pressure of the horizontal limb 61 is continued, the withdrawal applied to the valve stem 4 by the vertical limb 62 will be removed. The stress in the direction increases more and more, and the stress finally increases the elasticity of the coil spring 5 and the sealing O-ring 22.
Overcoming the sum of the frictional force caused by this and the frictional force caused by the stopper 41, the stopper 41 is removed from the injection port 32 at the same time as the valve stopper 4 retreats, and the injection port 32 is opened. The liquid in the nozzle barrel 3, which is already under sufficient pressure as described above, is thus injected, followed by the injection of the liquid in the container. That is, according to this invention, the opening of the injection port 32 is delayed relative to the opening of the injection valve. In this way, the opening of the injection port 32 is slow, so the small amount of liquid filled in the passage from the injection valve to the injection port 32 is subjected to strong pressure by the propellant in advance with the injection port 32 closed during the injection operation. As a result, an extremely good spray condition is obtained from the beginning as soon as the injection port 32 opens, and as a result, an extremely good spray condition is obtained from the beginning, and no dripping or dripping occurs from the injection port.

することができる。(Effect of the invention) Thus, according to this invention, since the injection port is closed during normal times, the liquid inside the injection port is kept cleaner than the injection port, and liquid dripping is prevented from the beginning of the injection operation. It is possible to obtain excellent spray conditions without dripping or dripping. In addition, according to this invention, the injection valve inside the container body can be used as is, so there is no need to manufacture the injection container body as a special structure different from ordinary aerosol injection containers, and it has become more popular than ever. Since the inexpensive injection container body can be used as is, it is possible to provide an excellent and economical aerosol injection means, especially when it is required to ensure the cleanliness of foods and other injection liquids.
