【産業上の利用分野】この発明は、燃料容器等の、特に
内部に液体が貯蔵される容器中に、ウレタンフォ−ムを
均一に圧縮充填する方法に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for uniformly compressing and filling a urethane foam into a fuel container or the like, particularly a container in which a liquid is stored.

ある。BACKGROUND OF THE INVENTION In liquid containers, there are certain problems with the container being excited by the conditions of dynamic use. that is,
This is a drawback caused by the liquid in the container moving to one end of the container in the dynamic use state, that is, the center of gravity of the liquid moving due to the movement of the liquid in the container in the dynamic use state. That is, the sloshing phenomenon occurs in the container.

たものである。On the other hand, when the liquid in the container is discharged, uniform discharge cannot be expected if the liquid in the container swings. As a measure to solve these problems, there is an idea of filling a urethane foam material into a container in order to prevent the movement of the liquid. For example, Japanese Patent Publication 42-210
This is the technique disclosed in Japanese Patent Laid-Open No. 3 and is summarized as follows. A urethane foam is filled in a container to store a liquid. The purpose of this is to prevent a large movement of the liquid.

状態にあるときは少なからず液体の移動が起り、かつ、
液体の排出も均質に行われるとはいい難く、前述の問題
点を全面的に解決したものとは言えなかった。However, this technique also has the following problems. That is, since the urethane foam of a volume commensurate with the inside of the container is merely filled, the capillary phenomenon cannot be expected so much in the urethane foam, the liquid holding capacity is inferior, and the container is in a dynamic use state. When there is a large amount of liquid movement, and
It is hard to say that the liquid is uniformly discharged, and it cannot be said that the above problems are completely solved.

ことはできない。With respect to this point, it has been found that these drawbacks can be eliminated by filling the urethane foam in the container in a compressed state, but there is a problem in compressing and filling the container in the container. Has a problem that it is difficult to uniformly compress the urethane foam evenly.
When the urethane foam is simply compressed, unevenness in compression occurs, the unevenness remains in the form of streaks, and the liquid concentrates along the streaks to exert the effect of the characteristic container. Can not.

Such a urethane foam may be the one with the cell membrane attached at the time of foaming, but a so-called open cell without the cell membrane is preferably used. Open cell phone with the cell film removed
The method of forming a foam (three-dimensional reticulated foam) is, for example, by immersing in an alkaline aqueous solution or by an explosive method. Further, in the filled state of the urethane foam, it is compressed and filled in the cavity of the container, but in general, it is compressed in the minor axis direction of the cell of the foam, The compression may be mechanically compressed, or may be permanently deformed by, for example, thermal compression.

が原因となって大きなしわが生じてしまう。In the structure of the urethane foam, the bubbles forming the urethane foam are not a spherical shape but a series of egg-like bubbles. That is, when a urethane foam is manufactured, a polyol and a polyisocyanate are used.
It rises from the liquid raw material mixed with g. The rising direction is the major axis direction of the bubbles, and the direction perpendicular to this is the minor axis direction of the bubbles. However, when the foam is compressed by matching it with the direction of the major axis, the compression cannot be performed uniformly and unevenly, resulting in uneven compression, and in some cases, this causes large wrinkles.

である。INDUSTRIAL APPLICABILITY As described above, the present invention is a method of filling a urethane foam into a container by a process in which the directions of compression and pressing are different. The method of filling the urethane foam is compression filling. Since the urethane foam to be filled is uniformly compressed and filled, for example, when this is used for a fuel container, there is no great fluctuation in the fuel liquid inside, and the discharge and supply of the fuel liquid from the container is always performed. It will maintain a certain state, and its effect will be great. Therefore, the scope of application of the present invention is large, and it is widely used as a method for filling a urethane foam into a container used for supplying various oils, paints, inks, etc., not limited to a fuel container. It is a thing.
