Description

A valve for admitting only one-way flow}

The present invention relates to a valve that can flow only in one direction, and more particularly, to a valve for allowing gas, such as gas, to flow out in one direction.

Conventionally, in packaging materials for packing various materials such as fertilizers, feed, compost, chemical products, food, and the like, packaging materials are packaged after the materials are put. During this packaging, as the packaging material is sealed, gas enters the packaging material. When the packaging material in which gas enters in this way is stacked (when piled up in a high stage at the time of pallet loading), the packaging material is bulging due to the gas in the packaging material. Therefore, when the packaging material is loaded at a certain height or more, there is a fear of collapse, so that it is often impossible to load safely.

In addition, if the material in the packaging material is a fermentation material, the material is fermented to release a gas, such gas will expand the packaging material. Therefore, the gas is expanded in such a packaging material and becomes full in the packaging material during long-term storage, and an accident may occur due to the gas pressure when the packaging material bursts due to an unavoidable impact during transportation or movement. In addition, due to the toxicity of the gas generated when the general user opens the package, it can not only smell bad, but also cause serious harm to health.

Until now, in order to prevent such a risk, there is a case in which a separate pinhole (pin-hole) is used in the packaging material itself, but in this case, foreign substances, moisture, etc. may penetrate through the pinhole and damage the contents.

The present invention is intended to solve the above problems. In other words, the present invention uses a valve to allow gas such as gas to flow out in only one direction, and in relation to the logistics management of the packaging material, in particular, when it is stacked (when stacked at a high stage during pallet loading), the gas inside the packaging material, etc. Allow gas to escape naturally from inside the packaging. Therefore, it is easy and safe to load and store the packaging material to a certain height or more, thereby improving efficiency in terms of logistics management.

In addition, when the material inside the package is a fermentation material, gas or the like generated inside the packaging material can be discharged to the packaging material at a simple pressure (that is, a pressure enough to hold the packaging material, etc.), but the outside gas is introduced into the packaging material. It is to provide a valve that can flow in only one direction to prevent inflow.

Therefore, the present invention not only prevents the risk of an accident due to the pressure of gas or the like in the packaging material, but also protects the user from harmful gases such as odor when the packaging material is opened.

In addition, the present invention is to provide a valve that can flow in only one direction attached to the packaging material in a simple configuration and low price.

In addition, Figure 2c shows a disk-shaped composite pad portion (C) according to the present invention, which is composed of a cushion and breathable material 200 and the material 100 to block the gas flow.

As shown in FIGS. 2A and 2B, the annular portion 3 of the first body A and the annular recess 30 of the second body B are matched and engaged at the time of engagement. The outer diameter d1 of the annular portion 3 is larger than the outer diameter d3 of the cylindrical portion 2 by a predetermined size, and the outer diameter d2 of the annular recess 30 is the inner diameter d4 of the cylindrical portion. Larger than a predetermined size. In addition, as described above, the outer diameter d1 of the annular portion 3 and the outer diameter d2 of the annular recess 30 are such that the annular portion 3 and the annular recess 30 are matched at the time of engagement. It is configured almost identically.

In addition, the outer diameter d3 of the cylindrical portion 2 in the first body A and the inner diameter d4 of the cylindrical portion 20 in the second body B are substantially the same.

As such, in the present invention, but not limited to, the diameters of the holes 4 and 40 of the first body A and the second body B are preferably about 3 mm, respectively. In addition, although not limiting, the inner diameter d5 of the cylindrical portion 2 formed on the disc portion 1 of the first body A is 1-4 mm larger than the outer diameter of the disc-shaped composite pad portion C. Larger is preferred.

Thus, since the said annular part 3 and the annular recessed part 30 are comprised, after joining the said 1st body A and the 2nd body B, they become hardly separable. In other words, it is almost inseparable unless a significant physical force, i.e., a driver or the like is inserted between the first body A and the second body B, for example, and is pulled out with a considerable force.

In addition, although the outer diameter of the disk-shaped composite pad part C of this invention is not restrict | limited, about 8 mm is preferable.

Next, with reference to Figures 3a to 3c, the operating principle of the valve that can flow only in one direction according to the present invention will be described.

3A is a cross-sectional view when the valve capable of flowing in only one direction according to the present invention is coupled to the packaging material D. FIG. 3C is a cross-sectional view showing the principle that the inflow of external gas into the packaging material D is blocked.

First, referring to Figure 3a, the first body (A) and the second body (B) is inserted into each other in the packaging material (D) is formed a hole of the appropriate size, where the first body (A) in the disc shape The composite pad portion C is inserted. As shown in FIG. 3A, the first body A and the second body B may be interchanged with each other. That is, the first body A is inside the packaging material and the second body B is outside the packaging material. The left view of FIG. 3A shows that the first body A is outside the packaging material and the second body B is The right side is inside the packaging.
