【０００４】[0004]
【考案の実施の形態】本考案に係る粉体包装用紙袋は、図１に示すように袋 本体１の口部左右に三角折曲部２、３を形成し、両三角折曲部２、３にわたつて 平行の折曲線４、５を施し、その外側を口部閉鎖片６、７とする。そして図２に 示すように折曲線４、５の間に一方の三角折曲部２側に偏して偏平に畳んだ状態 の筒状弁８を接着するが、この筒状弁８は図７に示すように内面に熱溶融性接着 剤層９を形成し、粉体充填後筒状弁８の部分を加熱することにより弁の内側全体 を接着させる。又他方の三角折曲部３に偏して密封紙片１０を当てその裏面にコ 形に接着剤ｎを塗布して一部を口部閉鎖片６、７に、他の一部を三角折曲部３に 接着し、口部閉鎖片６、７の外側の三角部２ａ、３ａ及び口部閉鎖片７の端部に 接着剤ｎを塗布して（図２参照）図３及び図４に示すように折曲げて接着し、そ の上に図５に示すように化粧紙１１を貼つて袋は完成する。又筒状弁８は図９に 示すように注入口８ａの両端に短いスリット１２を、又他端の送出口８ｂの両端 に比較的長いスリット１３を設けてもよい、この場合注入口８ａはスリット１２ により口部が開き易くなり粉体注入ノズルの挿入が容易となる。又送出口８ｂに 設けた長いスリットは粉体充填後の内圧によるストップ弁としての作用効果が増 大するものである。尚上記実施例には一層の図面が記載されているが、通常は多 層に形成される。DESCRIPTION OF THE PREFERRED EMBODIMENTS The powder packaging paper bag according to the present invention has triangular bent portions 2 and 3 on the left and right sides of the mouth of a bag body 1 as shown in FIG. The parallel folding curves 4 and 5 are applied over 3 and the outsides thereof are mouth closing pieces 6 and 7. As shown in FIG. 2, a cylindrical valve 8 which is flat and folded toward one of the triangular bent portions 2 is bonded between the fold curves 4 and 5, and this cylindrical valve 8 is formed as shown in FIG. As shown in (1), a hot-melt adhesive layer 9 is formed on the inner surface, and after filling with powder, the portion of the tubular valve 8 is heated to bond the entire inside of the valve. Also, a sealing paper piece 10 is applied to the other triangular bent portion 3 in a biased manner, and an adhesive n is applied to the back surface thereof in a U-shape. Adhesive n is applied to the triangular portions 2a, 3a outside the mouth closing pieces 6, 7 and the end of the mouth closing piece 7 (see FIG. 2) as shown in FIGS. Then, the bag is completed by attaching the decorative paper 11 thereon as shown in FIG. As shown in FIG. 9, the cylindrical valve 8 may be provided with short slits 12 at both ends of the inlet 8a and relatively long slits 13 at both ends of the outlet 8b at the other end. The slit 12 facilitates opening of the mouth and facilitates insertion of the powder injection nozzle. In addition, the long slit provided in the delivery port 8b increases the effect as a stop valve due to the internal pressure after the powder is filled. Although the above embodiment shows a single-layer drawing, it is usually formed in multiple layers.
【０００５】[0005]
【考案の効果】本考案によれば、筒状弁の内側全面に熱溶融性接着剤層を設 けてあるので、粉体充填後弁部を加熱することで筒状弁の内側全体が接着される ので、確実に密封され、充填した粉体が漏洩するおそれがない。又筒状弁の反対 側を密封紙片で被覆しているため袋体口部全体を確実に密封することができる。 更に筒状弁は前述のよう注入口にスリットを施すことで粉体注入用ノズルの挿 入が容易となり、又送出口に設けたスリットにより粉体充填後の内圧によるスト ップ弁としての作用効果は増大する。[Effects of the Invention] According to the present invention, a heat-meltable adhesive layer is provided on the entire inner surface of the cylindrical valve. Therefore, there is no danger of leakage of the filled powder. Also, since the opposite side of the cylindrical valve is covered with a sealing paper piece, the entire mouth of the bag body can be securely sealed. In addition, the cylindrical valve has a slit at the injection port to facilitate insertion of the powder injection nozzle as described above, and the slit at the delivery port acts as a stop valve due to internal pressure after powder filling. The effect increases.
