【具体实施方式】  【detailed description】
下面结合附图与具体实施方式对本发明作进一歩的描述： 如图 1-5所示； 一种真空包装袋， 包括有袋体 3、 袋体活动封口 和位于袋体上的真空抽气阀 4， 袋体 3包括有一前袋片 1和一后袋片 The present invention will be further described with reference to the accompanying drawings and specific embodiments. As shown in FIG. 1-5, a vacuum packaging bag includes a bag body 3, a bag body active sealing and a vacuum suction valve on the bag body. 4, the bag body 3 includes a front bag piece 1 and a back bag piece
2， 在前袋片 1下部和后袋片 2下部的边缘处通过热封合并使前袋片2, at the edge of the lower part of the front pocket piece 1 and the lower part of the back pocket piece 2, the front bag piece is combined by heat sealing
1和后袋片 2形成袋体 3， 在袋体 3上开设有一真空抽气阀 4。 即前 袋片 1下边和后袋片 2下边热封合，前袋片 1下部侧边和后袋片 2中 下部侧边热封合， 使前袋片 1和后袋片 2形成袋体 3， 这样的袋体 3 的底部为一尖底如图 1、 2、 3所示。 一般来说袋体 3的材质为塑料。 当然前袋片 1和后袋片 2下边之间也可以根据需要连接有其它连接片 10， 使袋体 3的底部变成平底， 如图 4、 5、 6所示。 1 and the back pocket sheet 2 form a bag body 3, and a vacuum suction valve 4 is opened in the bag body 3. Immediate The lower side of the bag piece 1 and the lower side of the back bag piece 2 are heat-sealed, and the lower side of the front bag piece 1 and the lower side of the back bag piece 2 are heat-sealed, so that the front bag piece 1 and the back bag piece 2 form the bag body 3, The bottom of the bag body 3 has a pointed bottom as shown in Figs. 1, 2, and 3. Generally, the bag body 3 is made of plastic. Of course, other connecting pieces 10 may be connected between the front bag piece 1 and the lower side of the back bag piece 2 as needed, so that the bottom of the bag body 3 becomes a flat bottom, as shown in FIGS. 4, 5, and 6.
所述前袋片 1上部和后袋片 2上部的未热封处张开后形成一开叉 口 8， 该开叉口 8呈 Y形状， 如图 1、 7所示。 在袋体上还设有一与 上述开叉口 8接合的盖片 5，该盖片 5包括有连接边 52和活动边 51。 所述盖片 5的连接边 52分别与上述开叉口 8处的前袋片 1和后袋片 2的边缘处热封， 使其密封连接。  The unsealed portion of the upper portion of the front pouch sheet 1 and the upper portion of the back pouch sheet 2 is opened to form a split mouth 8, which has a Y shape, as shown in Figs. A cover sheet 5 joined to the slit opening 8 is further provided on the bag body, and the cover sheet 5 includes a connecting side 52 and a movable side 51. The connecting edges 52 of the cover sheets 5 are heat-sealed with the edges of the front and rear pocket sheets 1 and 2 at the slits 8, respectively, to be sealed.
所述盖片 5的活动边 51则与上述开叉口 8处的前袋片 1上边缘 形成包装袋的开口 6， 在包装袋开口 6处设有一用于开合包装袋开口 6的扣合装置 7。所述扣合装置 7由设置在盖片 5上的凹槽 72及设置 在前袋片 1上边缘处并可插入凹槽 72内的凸条 71组成， 凸条 71卡 入凹槽 72 内完成封合。 具体来说所述凹槽 72设在盖片 5的活动边 51上， 凸条 71设在前袋片 1的上边， 如图 3、 图 6所示。  The movable edge 51 of the cover sheet 5 forms an opening 6 of the packaging bag with the upper edge of the front pocket piece 1 at the slit opening 8, and a fastening for opening and closing the opening 6 of the packaging bag is provided at the opening 6 of the packaging bag. Device 7. The fastening device 7 is composed of a recess 72 disposed on the cover sheet 5 and a rib 71 disposed at an upper edge of the front pocket piece 1 and insertable into the recess 72. The rib 71 is engaged in the recess 72. Sealed. Specifically, the recess 72 is provided on the movable side 51 of the cover sheet 5, and the rib 71 is provided on the upper side of the front pocket piece 1, as shown in Figs.
如图 9所示； 如上所述的真空袋还可与硬质的箱体 9组合使用。 由于在袋体 3的开口端顶部连接有盖片 5， 因此操作者将棉被放 入袋体内时，袋体 3不会因为棉被放入后使其膨胀而导致开口 6无法 合拢， 封闭开口 6更加简单、 更加省力、 快捷， 另夕卜， 袋体的开口可 以根据棉被的大小而设置。该真空袋还可以与一种箱体 9如无纺布箱 等进行组合使用， 以对真空袋起到保作用， 延长使用寿命。 以上实施例是供理解本实用新型之用，并非是对本实用新型的限 制， 有关领域的普通技术人员， 在权利要求所述技术方案的基础上， 还可以作出多种变化或变型， 例如本发明所述袋体也可以由一前袋 片、 一后袋片及条状的侧袋片构成， 还可以由一前袋片、 一后袋片、 一条状的底袋片及条状的侧袋片构成，另外还可以由无缝管的一端封 合构成。所述的各个袋片边缘的结合可以不限于热封工艺， 其它形式 的结合工艺如粘合或者物理方式的装订均可。 As shown in Fig. 9, the vacuum bag as described above can also be used in combination with the rigid case 9. Since the cover sheet 5 is attached to the top of the open end of the bag body 3, when the operator puts the quilt into the bag body, the bag body 3 does not expand due to the quilt being placed, and the opening 6 cannot be closed, and the opening is closed. 6 is simpler, more labor-saving and quicker. In addition, the opening of the bag body can be set according to the size of the quilt. The vacuum bag can also be used in combination with a box 9 such as a non-woven box to protect the vacuum bag and prolong its service life. The above embodiments are for the understanding of the present invention, and are not intended to limit the present invention. Those skilled in the relevant art can make various changes or modifications based on the technical solutions of the claims, for example, the present invention. The bag body may also be composed of a front bag piece, a back bag piece and a strip side bag piece, and may also comprise a front bag piece, a back bag piece, a strip bottom bag piece and a strip side bag.
