    • The easily openable synthetic resin bag substantially comprises a) a bag body having in an overlapped state front and rear walls of substantially rectangular shape, and a bottom wall interposed between the lower ends of the front and rear walls and having opposite side edges folded down in an inverted V-shape, and b) a tear string heat sealed on the inner side of the rear wall along an opening line at the upper end of the bag body and having opposite end portions thereof heat sealed in gripped state between corresponding portions of the lateral marginal seal portions of the bag body; the bag body having a width gradually broadened in a tapered fashion from the upper to lower end thereof. Accordingly, when the bag body is packed with a filling material and undergoes reductions in width in bag portions packed with the filling material, such bag portions still have a width which substantially equivalent to or which is not markedly smaller than the width of the unfilled upper bag portions. Therefore, when put on a shelf or a similar support surface, the bag can stand there in a quite stabilized state.
    • 容易打开的合成树脂袋基本上包括:a)具有重叠状态的袋体,前壁和后壁具有大致矩形形状,底壁插入在前壁和后壁的下端之间,并且具有向下折叠的相对侧边 倒V形,以及b)沿着袋体上端的开口线热封在后壁的内侧的撕裂线,并且其相对的端部在夹持状态下被相互的部分热封 袋体的侧边缘密封部分; 所述袋体的宽度从其上端向下端逐渐变宽。 因此,当袋体填充填充材料并且在填充有填充材料的袋部分中减小宽度时,这些袋部分仍然具有基本上等于或不显着小于未填充的上部的宽度的宽度 袋部分。 因此,当放在搁板或类似的支撑表面上时,袋可以处于非常稳定的状态。

    • An easy-to-open synthetic resin bag comprising: a bag body constituted by a laminated film formed by laminating several layers of synthetic resin film; a tear string bonded to part of an inner surface of the bag body corresponding to the opening thereof; and a tab formed at an end of the tear string; whereby pulling the tear string by the tab enables one side surface of the bag to be torn open, thereby allowing the bag to be opened. Also disclosed is a bag manufacturing apparatus capable of automatically bonding the tear string to the part of the inner surface of the bag body corresponding to the opening thereof when the bag body is being formed by employing the laminated film of the above kind.
    • 一种易于开放的合成树脂袋,包括:袋体,由通过层压多层合成树脂膜形成的层压膜构成; 与所述袋体的内表面的与其开口对应的一部分结合的撕裂线; 以及形成在所述撕裂线的端部处的突片; 由此通过拉片拉动撕裂线使得袋的一个侧表面被撕开,从而允许袋打开。 还公开了一种袋制造装置,其能够通过使用上述层压膜来形成袋体时,能够将撕裂线自动地接合到与其开口对应的袋体的内表面的部分。

    • Disclosed is a gas relief valve for a container for storing contents generating gases, having a support member having an aperture through which to discharge gases when they are filled in the container, when the gas relief valve is mounted on the container; an opening or closing member which closes the aperture of the support member in a normal state and which is caused to open by the gases discharged from the aperture when the gases filled in the gas relief valve reaches a predetermined inner gas pressure; and a pressing member disposed outside the opening or closing member so as to cause the opening or closing member to close the aperture of the support member so as to allow air outside the gas relief valve to fail to enter therein after the gases filled in the gas relief valve are discharged therefrom.
