Abstract

PROBLEM TO BE SOLVED: To prevent the engagement of a container main body and a cap from becoming insecure due to the adherence of a leaked liquid on the engaging surfaces of the container main body and the cap by a method wherein on the top surface in the cap where a needle pin is provided, a liquid reservoir part is provided, and the cap is constituted in such a manner that a leaked liquid which generates when the cap is removed from the container main body, is taken into the liquid reservoir part by the needle pin. SOLUTION: This liquid container consists of a container main body 1 which has a discharging port 4 at the tip of a nozzle part 3, and a cap 5 which is engaged with the container main body 1, and wherein a needle pin 6 of which the forward part is inserted in the discharging part 4, is provided. A liquid reservoir part 7 which is provided on the internal top surface of the cap 5 is constituted by forming a large number of recesses into a ring-shape, or of an annular groove, etc. The shape of the liquid reservoir part 7 can be simultaneously formed when the cap is formed, and it is advantageous cost-wise. Therefore, a leaked liquid which generates when the cap 5 is removed from the container main body 1, does not stick to the engaging surfaces between the container main body 1 and the cap 5, and is reserved or lead out to other part, and the engagement between both parts is prevented from becoming insecure.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a cyanoacrylate.
Containers for liquids that dislike moisture, such as instant adhesives that absorb water in the air and solidify and become unusable, especially when the cap is disengaged due to leaking liquid The present invention relates to a liquid container in which moisture is disliked as much as possible.

[0002]

2. Description of the Related Art A description will be given with reference to FIG. Reference numeral 1 internally has a liquid storage chamber 2 for storing a liquid such as a cyanoacrylate type instant adhesive that absorbs water in the air to solidify and become unusable. A nozzle portion 3 is fixed to the front of the nozzle portion 3, and a discharge hole 4 is provided at the tip of the nozzle portion 3.
The container is in a closed state until the start of use, and is a container main body having a needle pin 6 on the top surface of the cap 5 which will be described later when in use.
It is made of polypropylene, polyethylene terephthalate, nylon, or the like, and at least a part of the liquid storage chamber 2 is pressurized by pressing at least a part of the liquid storage chamber 2 so that the liquid can be discharged to the discharge hole 4. It is made of synthetic resin having elastic restoring force. The nozzle part 3
It is known that the one is integrally molded and the other is integrally molded and then integrated. Reference numeral 5 is a cap that is engaged with the container body 1 by means such as fitting, screwing, or simply press fitting, and the cap 5 has needle pins 6 planted on its inner top surface. It should be noted that the needle pin 6 is inserted and arranged in the discharge hole 4 as shown in the figure during storage after the start of use.

[0003]

When the cap 5 is to be used from the state of storage shown in FIG. 10, the cap 5 is first detached from the container body 1. However, when the cap 5 is detached, a problem may occur. Become. The problem is, as a conclusion, that the engagement between the container body 1 and the cap 5 becomes uncertain, but it is roughly classified into the following two depending on the position of the container body at the time of detachment. The problem at the time of detaching the cap 5 is that, like the engagement by fitting, the container body 1
Occurs remarkably when the cap 5 and the cap 5 are more reliably engaged with each other to more reliably block the air inside the cap from the outside air (air-tight).

The first problem is a problem which occurs when the container body (cap) is directed upward and the cap 5 is removed. When the cap 5 is removed, the cap 5 is in a depressurized state and the liquid is sucked up. The sucked liquid is transmitted from the discharge hole 4 of the nozzle portion 3 to the outer peripheral surface of the nozzle portion 3 and finally reaches the engagement surface with the cap 5 and is solidified there. As a result, the subsequent engagement between the container body 1 and the cap 5 cannot be ensured (if the liquid is not solidified, the container body 1 and the cap 5 may be bonded), and the container body 1 and the cap 5 There is a problem that the air flows in from between 5 and the tip portion of the nozzle portion 3 is solidified by the moisture contained in the air, which hinders the subsequent use.

The second problem is a problem that occurs when the container body (cap) is oriented horizontally or downward and the cap 5 is removed. When the cap 5 is removed, the cap 5 is depressurized and liquid Part of the liquid is transmitted from the discharge hole 4 of the nozzle portion 3 to the outer peripheral surface of the needle pin 6 by its own weight,
It moves to the inner top surface of the cap 5, and finally reaches the engagement surface with the cap 5. When the cap 5 is engaged with the container body 1 in such a state, the liquid that has moved to the inner top surface of the cap 5 flows along the inner surface of the cap 5 to the engagement surface between the container body 1 and the cap 5. As in the first problem, the engagement between the container body 1 and the cap 5 is not ensured, and the subsequent use is hindered.

[0006]

SUMMARY OF THE INVENTION An object of the present invention is to provide a liquid container which is free from moisture which is free from the engagement failure of the cap that occurs after the cap is removed. Based on the assumption that it is difficult to prevent the phenomenon of flowing from the outer circumference of the part or the top surface inside the cap from the needle pin, it is conceivable that the flowing liquid should be led to a part that does not affect the engagement of the cap. The present invention has been completed based on, and has a liquid storage chamber for storing a liquid that dislikes water inside, and a container main body having a discharge hole at the tip of the nozzle portion, and engaging the container main body, The front side of the inner top surface is composed of a cap provided with a needle pin to be inserted and arranged in the discharge hole, and the water in the liquid storage chamber is drawn out from the nozzle tip by pressurizing the liquid storage chamber. Hate liquid A liquid container which is provided with a liquid retaining portion on the top surface of the cap provided with the needle pin and takes in the leaking liquid generated when the cap is detached from the container body into the liquid retaining portion from the needle pin. The first gist of the invention, a container main body having a liquid storage chamber for storing a liquid that dislikes moisture therein, having a discharge hole at the tip of a nozzle portion, an outer container main body storing the same, and the outer container main body And a cap provided with a needle pin on the inner top surface of which the front portion is inserted and arranged in the discharge hole. By pressing the liquid storage chamber, the liquid in the liquid storage chamber is drawn out from the tip of the nozzle. In the liquid container which does not like water, the container body is arranged such that the nozzle portion is projected in the outer container body, and the first body is connected between the tip of the outer container body and the container body to communicate with the inside of the cap. Set up space Second communicating with the first space between the outer container body inner surface and the container body outer surface
And a second liquid container which dislikes water such that leaking liquid generated when the cap is detached from the outer container body is taken into the first and second spaces from the outer periphery of the nozzle.
Is the summary of.

[0007]

In the present invention, since the liquid retaining portion is provided on the top surface of the cap provided with the needle pin, the leaking liquid generated when the cap is detached from the container body can be taken into the liquid retaining portion from the needle pin. According to the present invention, a first space portion communicating with the inside of the cap is provided between the outer container body tip portion and the container body, and a second space communicating with the first space portion between the outer container body inner surface and the container body outer surface. Since the portion is provided, the leaking liquid generated when the cap is detached from the outer container main body can be taken into the first and second spaces from the outer periphery of the nozzle, and the leaking liquid is the relationship between the container main body (outer container main body) and the cap. The problem that they adhere to the mating surface and the engagement of the two becomes uncertain is eliminated as much as possible.
