Description

Test solution pack and composition to block the contact of the solution with air{STORAGE PACK FOR EXPERIMENTAL LIQUID}

The present invention relates to a test solution pack and configuration for blocking contact of a solution with air, and when using a solution in the environment and chemical fields, the solution is prevented from being oxidized and contaminated by blocking contact with air. As injection and discharge are possible without use, contamination by the syringe is prevented, and safety accidents due to leakage of the solution can be prevented in advance by further providing a valve so that it can be discharged only when a certain pressure is applied. It relates to a test fluid pack and configuration for blocking the contact of the solution with air.

In general, in the field of environment and chemical engineering, a solution prepared at a certain concentration is repeatedly used, so a large amount of solution is prepared and used in a container.In some cases, such a solution is composed of strong acids and strong bases, so safe storage of the solution is essential. In addition, it should be stored so as to prevent deterioration of the solution.

As such a prior art, there is disclosed Patent Publication No. 10-1998-0009055 "Chemical Solution Container",

And at least one mold separation seam or combination of materials due to manufacturing presents a container that is placed vertically with respect to the floor, respectively.

However, as mentioned above, the prior art also has a problem in that it is impossible to completely block air and there is a risk of safety accidents, and a more accurate experiment cannot be performed due to contamination, deterioration, reaction, etc. of the solution.

Therefore, the present invention is conceived to solve the above problem,

Consisting of a body having a receiving part for receiving a solution, an injection line, and a discharge line, and a cap detachably coupled to the discharge line, the body is composed of a sealed member made of PP or LDPE, specifically a sealed pouch. The purpose of this study is to provide a test solution pack that prevents the solution from being oxidized by contact with air.

In addition, an object of the present invention is to provide a test fluid pack comprising a valve further provided in the discharge hole formed in the discharge line so that the solution can be discharged only when a certain pressure is applied.

Furthermore, the cap is composed of a first cap that closes the discharge line, and a second cap that can automatically supply a solution to a separate device through an infusion tube provided with an infusion tube, thereby providing a test fluid pack that enhances the convenience of use. Is another purpose.

In order to achieve the above object, the test fluid pack according to the present invention

As shown in Figs. 1 to 3, the test fluid pack P and configuration for blocking contact of the solution with air according to the present invention are largely composed of a main body 10 and a cap 20.

When the main body 10 is described in more detail with reference to FIG. 1, the main object of the present invention is to accommodate a solution prepared at a certain concentration in the environment and chemical fields so as not to come into contact with air. (10) is made in the shape of a sealed member, more precisely, a pack sealed so that all sides are sealed, and a receiving portion 11 is formed therein to store a solution.

The material of the main body 10 is preferably made of PP (Polypropylene) or LDPE (Low Density Polyethylene) material, and is preferably formed in double or triple in order to completely block contact with air.

PP is a thermoplastic resin obtained by polymerizing propylene, and propylene is produced with ethylene when naphtha is decomposed in a petrochemical plant, and a Ziegler-Natta catalyst (typical is a complex salt consisting of titanium trichloride and diethyl aluminum chloride) is added to the nucleic acid. It is easily synthesized by making and passing propylene therein at about 70°C and 5 atm. It has an isotactic structure, and thus methyl groups are arranged in the same direction as shown in the structural formula. The melting point is 165℃, and continuous use under load is possible at 110℃. The density is 0.9 to 0.91, and the crystallinity is large, but after molding, it decreases to 70% or less. The electrical properties are excellent because it consists only of carbon and hydrogen, and is second to that of polyethylene. Polypropylene, along with polyethylene, PVC, and polystyrene, is one of the four major general-purpose resins, and the proportion of thermoplastic resins used is 24%. It also has the advantage of being advantageous in terms of cost and environment. Applications are variously used as packaging films, stretched tapes, and the like.

LDPE refers to low-density polyethylene. It is a synthetic resin produced by polymerizing ethylene. It is a transparent solid (density of 0.91 to 0.94) at room temperature and has low crystallization and has excellent processability, flexibility, and transparency. , It is used as a raw material for various wraps.

The solution in the present specification is generally composed of reagents used in the test, and refers to all reagents prepared for the test, acidic, basic, neutral, and the scope of the rights is not limited thereto.

The main body 10 generally has a quadrangular shape as shown in the drawing, but is not limited thereto and may be configured in various shapes, and a separate mounting hole 17 for mounting the main body 10 in the upper portion thereof. ) Is formed, and it is possible to form a fixing part 31 as in another embodiment shown in FIG. 3, which will be described in more detail below.

It is preferable that the rim of the main body 10 is formed so as to form the sealing portion 12 through a sealing process using heat, so that air is not introduced into the body 10 so as to be completely blocked.

A separate injection line 13 for injecting a solution into the receiving part 11 and a discharge line 15 for discharging the solution in the receiving part 11 are respectively provided below the main body 10.

First, the injection line 13 is provided for injecting a solution into the receiving portion 11, and when the infusion pack P according to the present invention is manufactured, the injection line 13 includes the receiving portion 11 and The injection hole 131 of the injection line 13 is kept open to communicate with each other.

Accordingly, when a user injects a solution, a separate tube is connected to the injection line 13 to inject the solution, and then thermocompression and cutting are performed to close the injection hole 131, so that the solution goes to the outside. Try to prevent air from entering the interior while preventing it from flowing out.

At one side of the injection line 13, a discharge line 15 for discharging the solution in the receiving part 11 is formed, and the discharge line 15 is a discharge hole 151 communicating with the receiving part 11 As the formed tube, it is preferable that it is formed under the main body 10.

The present invention further includes a separate cap 20 to prevent the solution from leaking out through the discharge hole 151, wherein the cap 20 includes a first cap 21 and a second cap. (22) consists of one set,

The first cap 21 is a cap 20 provided in the discharge line 15 to close the discharge hole 151 of the discharge line 15 when not in use, that is, when the solution is stored without discharging, (See Fig. 1[A]]

The second cap 22 is a cap 20 designed to be injected without using a needle when in use, that is, when the solution is discharged to a device to be injected (more precisely, an automatic measuring device). (Fig. 1[B] Reference]

Specifically, the cap 20 has a separate thread 24 formed inside the cap 20 to be coupled to the discharge line 15, and the discharge line 15 corresponds to the thread 24, although not shown in the drawing. A corresponding screw portion is formed so that the cap 20 (referring to both the first cap 21 and the second cap 22) can be fastened to the end of the discharge line 15.

However, the screwing method is one embodiment, and although not shown in the drawings, any one of various conventional coupling methods, such as a coupling method of a protrusion and a groove, and a one-touch coupling method, may be adopted.

The first cap 21 is used to block the discharge hole 151 of the discharge line 15, and the shape may be variously implemented, but the second cap 22 supplies a solution to an automatic measuring device. The second cap 22 is provided with an injection pipe 221 that can be connected to an automatic measuring device at the bottom of the second cap 22, so that the user does not need to discharge the solution using a needle, etc. The problem of reacting the needle and the solution can be prevented in advance.

In addition, in the case of a strong acid or strong base solution, there is a problem that a burn may occur if the solution leaks out.

Accordingly, the present invention is characterized in that a valve 153 is further provided in the discharge line 15, more precisely, in the discharge hole 151 so that the solution can be discharged only when a certain pressure or more is applied.

The valve 153 is composed of a first film 153A and a second film 153B provided in the discharge hole 151, and ends of the first film 153A and the second film 153B are the The discharge hole 151 is closed as the discharge hole 151 contacts each other at the center of the discharge hole 151 and is bent downward as shown in FIG. 2.

At this time, when pressure is applied from the top, the first film 153A and the second film 153B are further formed so that the ends of the first film 153A and the second film 153B are separated from each other to form the opening 153C. By bending, the solution is discharged through the opening 153C.

For this, it is preferable that the first layer 153A and the second layer 153B are made of a material having an elasticity with a restoring force.
