Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention mainly relates to a container for dispensing liquids such as instant adhesives and lubricating oils, and particularly relates to improvements in pen-type liquid dispensing containers.

[Technical background of the invention and its problems]

Conventionally, the above-mentioned pen-type liquid dispensing container consists of a container body that stores liquid, a tapered nozzle that doubles as a cap screwed onto the mouth of the container, and a nozzle that can be slid into the nozzle and is constantly rotated in the direction of the tip using a spring mechanism. It consists of a valve body with a small protrusion that is attached under pressure, and under normal conditions, the valve body presses against the inner surface of the spout at the tip of the nozzle due to the elastic force of the spring mechanism, stopping the flow of the liquid content, and when in use. By pressing the small protrusion at the tip of the valve body protruding from the spout of the nozzle against the target adhesive surface, etc., and moving the valve body against the spring mechanism to mix the small protrusion into the nozzle, the nozzle tip The spout opens so that the liquid content can be poured out.

By the way, such a conventional pen-type liquid dispensing container is provided with a spring mechanism that presses the valve body so that the dispensing port of the nozzle is always closed.
The configuration is complicated, making design and manufacturing difficult, leading to high costs. In addition, the liquid content can be poured out from the nozzle spout by pressing the small protrusion at the tip of the valve body, but when the pressing force is released, the valve body immediately returns to its closed state due to the elastic pressure of the spring mechanism. This will stop dispensing any more liquid. In other words, each time the small protrusion is pressed, the valve body returns to closed position, and only one drop of liquid can be poured out with each press, making it troublesome to pour out the appropriate amount of liquid. Furthermore, when dispensing the liquid, the small protrusion must be pressed against the target adhesive surface with a strong force that resists the spring force, which may cause the adhesive surface to move or deform. Furthermore, if the liquid is to be dripped deep into a small gap, a long and thin adapter is fitted onto the small protrusion and the liquid is allowed to flow down from the spout along the adapter. A structure in which the valve body does not open unless it is strongly pressed has the problem that this is impossible because the adapter will break.

[Purpose of invention]

This invention was devised in view of the above circumstances, and the purpose is to provide a liquid dispensing container that is extremely simple and highly practical, and can satisfactorily solve all of the conventional problems.

[Summary of the idea]

In order to achieve the above object, the liquid dispensing container of this invention has a container main body for storing a liquid such as instant adhesive, and a tapered spout at the tip that is screwed into the mouth of the container main body. A pouring nozzle that also serves as a cap,
A valve that is installed inside the nozzle and has a small protrusion at its tip that can be retracted and retracted from the distal end of the nozzle, and when the small protrusion is pushed from the distal end side, it retracts into the nozzle and opens the spout. Be equipped with a body,
The valve body has a rod that passes through the nozzle and projects into the container body, and the rod is necessary for at least opening the spout from the closed state of the valve body against the proximal closing wall of the container body. The container body has a bellows-like part that is expandable and retractable in the axial direction, and when the proximal end closing wall is pressed from the outside, the valve body opens the nozzle spout. It is characterized by a structure in which the rod can be pushed toward the distal end in the closed state.

This eliminates the need for a conventional spring mechanism that constantly presses the valve body in the closing direction, so if you push the small protrusion at the tip lightly once and retract the valve body to open the spout, the valve body will open. The open state can be maintained as is. For this purpose, it is possible to pour out an appropriate amount of the liquid content, rather than just a single drop, and by fitting a long and thin adapter into a small protrusion, the liquid content flows down from the spout along the adapter and drips deep into the small gap. You will be able to do things like this without any hesitation. After dispensing the liquid, by pressing the proximal end closing wall of the container body from the outside, the bellows-like portion of the container body is shortened in the axial direction, and the inner surface of the proximal end closing wall moves the rod distally. It is very easy to use and simple, as it allows the valve body to be moved back easily and the nozzle spout can be completely closed.

[Example of idea]

An embodiment of this invention will be described below with reference to the drawings. First, 1 in the figure is a cylindrical container body with moderate elasticity molded from a material such as polyethylene that does not adhere to instant adhesives, etc., and has a male thread on the outer periphery with a smaller diameter on the side opposite to the proximal end closing wall 1a. The container body 1 is provided with a liquid filling opening 1b, and a bellows-shaped portion 1c that is extendable and retractable in the axial direction of the container body 1 is formed at a portion of the peripheral wall of the container body 1 near the proximal end.

A cap nozzle 2 is coaxially attached to the container body 1 by screwing into the mouth 1b thereof. This nozzle 2 is a gradually tapered cylindrical molded product made of the same material as the container body 1, and has a mounting part 2a with a female thread at the base end that fits and screws into the mouth part 1b from the inside and outside. However, the tip has a tapered spout 2b with a further increased angle.

Moreover, a valve body 3 with a small protrusion 3a is built into the nozzle 2. This valve body 3 is also a molded product made of the same material as the container body 1, and has a rectangular truncated cylindrical shape.
It has the small protrusion 3a on its distal end side and a long rod 3b on its opposite base end side, which are arranged coaxially and integrally. The rod 3b is retractable and extends through the nozzle 2 and extends into the container body 1 near its base end. In other words, the length of the rod 3b is such that the valve body 3 has a sufficient distance from the proximal end closing wall 1a of the container body 1 for at least the backward movement stroke required to open the spout 2b from the closed state. The rod 3b is pushed distally by pressing the proximal end closing wall 1a from the outside so as to shorten the bellows-shaped portion 1c of the container body 1, so that the proximal end comes into contact with the inner surface of the proximal end closing wall 1a. It's starting to become easier.

In the liquid dispensing container configured as described above, the valve body 3 with the small protrusion 3a and the rod 3b is inserted into the nozzle 2 from its proximal end, and the valve body 3 is inserted into the nozzle by pushing the end rod 3b with a finger. 2 spout 2b
It presses against the inner circumferential surface to close the spout 2b. The nozzle 2 with the valve body assembled is screwed into the opening 1b of the container body 1 filled with a liquid such as instant adhesive. This completes the sealed state as shown in Figure 1, and provides it to the user in a protective cover such as a pack, and the purchaser removes it from the protective cover.
When dispensing the liquid content, hold the vicinity of the base end of the nozzle 2 between your fingers and lightly press the small protrusion 3a protruding from the tip against the target adhesive surface or other appropriate location. 3 to open the spout 2b of the nozzle 2 as shown in FIG. In this state, the peripheral wall of the container body 1 is appropriately pressurized with fingers to pour out the liquid content from the spout 2b of the nozzle 2. After dispensing an appropriate amount of liquid in this manner, press the proximal end closing wall 1a of the container body 1 with your finger to shorten the container body 1 in the axial direction via the bellows-shaped portion 1c, while Rod 3b with end closing wall 1a
Push the valve towards the tip and move the valve body 3 to the nozzle 2.
The spout 2b is brought into pressure contact with the inner circumferential surface of the spout 2b to return to the initial closed state shown in FIG. 1, thereby completely stopping the outflow of the liquid content and storing it until the next use.

In addition, when dispensing liquid into a small gap, a long and thin adapter (not shown) is fitted into the small protrusion 3a at the tip of the valve body 3, and in this state, the base end of the adapter is pressed with a nail etc. Valve body 3 together with protrusion 3a
is moved in and out to open the spout 2b, and in this state, the peripheral wall of the container body 1 is pressurized to drain the liquid content into the spout 2b.
From b, guide it along the adapter into the detailed area for the above purpose.

[Effect of idea]

Since this idea was made as described above, the conventional spring mechanism is not required and the configuration is simple.
This makes it easier to design and manufacture, reducing costs.
In addition, by lightly pressing the small protrusion at the tip of the valve body once, the valve body can be maintained in an open state, allowing the desired amount of liquid to be poured out, and after the liquid has been poured out, the valve body can be returned from the outside of the container body. It is extremely simple and practical, as it can be moved and the spout can be closed easily and reliably.
