背景技术Background technique
粮食是人们每天都离不开的最重要的生活必需品。几乎每个家庭都要存放各种粮食，如：大米、面粉、玉米、豆类、其他谷物等。目前，市场上用于装粮食的袋子种类很多。但目前已经公开的粮食的封口一般为上下面对齐平切，采用针线缝包，缝包针对底向编织布的破坏影响会降低底向拉力，使袋子缝合不够牢固。另外，这种袋子在灌装后袋体两侧突出，影响美观；而且一年四季气候不断变化，袋内物品容易受外界湿度影响。阀口方底袋设计的底部和顶部图案设计简单，图案或颜色需采用二次印刷，容易出现色差，影响外观。Food is the most important daily necessities that people cannot live without. Almost every household needs to store various grains, such as: rice, flour, corn, beans, other grains, etc. At present, there are many types of bags for storing grain on the market. But the sealing of the publicly disclosed grains is generally aligned and cut up and down, and the bag is sewn with needles and threads. The destructive influence of the sewed bag on the bottom to the woven cloth will reduce the bottom to the pulling force, so that the bag is not firmly stitched. In addition, this kind of bag protrudes on both sides of the bag body after filling, which affects the appearance; and the climate changes constantly throughout the year, and the contents of the bag are easily affected by the external humidity. The design of the bottom and top pattern of the valve port square bottom bag is simple, and the pattern or color needs to be printed twice, which is prone to color difference and affects the appearance.

具体实施方式Detailed ways
下面结合附图对本发明的较佳实施例进行详细阐述，以使本发明的优点和特征能更易于被本领域技术人员理解，从而对本发明的保护范围做出更为清楚明确的界定。The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.
请参阅图1-图3，本发明实施例包括：Please refer to Fig. 1-Fig. 3, the embodiment of the present invention comprises:
一种梯形袋，由编织布与BOPP材料复合而成，包括：袋子本体1，所述袋子本体1为长方体结构，包括底部封口2、顶部封口3、底部粘合线4和顶部粘合线5。A trapezoidal bag, which is composed of woven cloth and BOPP material, including: a bag body 1, the bag body 1 is a cuboid structure, including a bottom seal 2, a top seal 3, a bottom bonding line 4 and a top bonding line 5 .
所述袋子本体1包括正面11、背面12、左侧面13和右侧面14，所述袋子本体1的背面12含有由热熔胶挤压粘合而成的折合部6，所述折合部6位于袋子本体1的背面12的侧边靠近右侧面14处。The bag body 1 includes a front side 11, a back side 12, a left side 13 and a right side 14. The back side 12 of the bag body 1 contains a hinged portion 6 formed by extruding hot melt adhesive, and the hinged portion 6 is located on the side of the back side 12 of the bag body 1 near the right side 14 .
所述底部封口2在所述袋子本体1的背面12上下错开呈阶梯形结构，且所述底部封口2处涂布有热熔胶层。所述阶梯形结构的底部封口2的阶梯形过渡部位含有底部圆弧倒角7，经热熔胶粘合后能够有效地防止内部灌装物的泄露。The bottom seal 2 is staggered up and down on the back 12 of the bag body 1 to form a stepped structure, and the bottom seal 2 is coated with a hot melt adhesive layer. The stepped transition part of the bottom seal 2 of the stepped structure contains a bottom arc chamfer 7, which can effectively prevent the leakage of the inner filling after bonding with hot melt adhesive.
所述顶部封口3在所述袋子本体1的正面11上下错开呈阶梯形结构，且所述顶部封口3处由使用方在灌装时涂布热熔胶层。所述阶梯形结构的顶部封口3的阶梯形过渡部位含有顶部圆弧倒角8，经热熔胶粘合后能够有效地防止内部灌装物的泄露。The top seal 3 is staggered up and down on the front side 11 of the bag body 1 to form a stepped structure, and the top seal 3 is coated with a hot melt adhesive layer by the user during filling. The stepped transition part of the top seal 3 of the stepped structure contains a top circular arc chamfer 8, which can effectively prevent the leakage of the inner filling after bonding with hot melt adhesive.
所述底部粘合线4高于所述袋子本体1的背面底边，所述顶部粘合线5低于所述袋子本体1的正面顶边。在本实施例中中，所述底部粘合线4高于所述袋子本体1的背面底边10mm，所述顶部粘合线5低于所述袋子本体1的正面顶边10mm。The bottom bonding line 4 is higher than the back bottom edge of the bag body 1 , and the top bonding line 5 is lower than the front top edge of the bag body 1 . In this embodiment, the bottom bonding line 4 is 10 mm higher than the back bottom edge of the bag body 1 , and the top bonding line 5 is 10 mm lower than the front top edge of the bag body 1 .
由于底部封口2处涂有热熔胶，封装时，只需将底部封口2沿顶部粘合线5折起，经挤压粘合即可；同理，顶部封口3处在灌装时涂布热熔胶，罐装后，顶部封口3沿底部粘合线4折起，经挤压粘合即可。Since the bottom seal 2 is coated with hot melt adhesive, when packaging, it is only necessary to fold the bottom seal 2 along the top bonding line 5, and then squeeze and bond; similarly, the top seal 3 is coated during filling Hot melt adhesive, after canning, the top seal 3 is folded along the bottom bonding line 4, and then glued by extrusion.
本发明的梯形袋经灌装后袋体仍呈长方体，底部封合平整，外观可视度优于缝包袋、阀口袋。The bag body of the trapezoidal bag of the present invention is still cuboid after being filled, the bottom is sealed smoothly, and the appearance visibility is better than that of a sewn bag or a valve bag.
本发明结构牢固，底向拉力优于缝包袋，在底部封口和顶部封口处涂布热熔胶，并通过挤压粘合，替代传统的针线缝包，避免缝包针对底向编织布的破坏影响降低拉力。The structure of the present invention is strong, and the bottom pulling force is better than that of the seamed bag. The bottom seal and the top seal are coated with hot melt adhesive, and bonded by extrusion, replacing the traditional sewing bag with needles and threads, so as to avoid seaming for the bottom woven fabric. The breaking effect reduces pull.
本发明结构外观设计美观，底部和顶部图案设计可以与袋体整体设计，图案排布融为一体，无脱节，印刷一次完成，可以避免阀口袋底部和顶部图案设计简单，图案或颜色因二次印刷出现色差，影响外观等问题。The structure design of the present invention is beautiful, the pattern design of the bottom and the top can be integrated with the overall design of the bag body, the pattern arrangement is integrated, there is no disconnection, and the printing is completed at one time, which can avoid the simple design of the bottom and top pattern of the valve bag, and the pattern or color due to secondary changes Chromatic aberration occurs in printing, affecting the appearance and other problems.
本发明结构密封性优良，优于缝包袋、卷口方底袋，适用于包装粉状、颗粒状等物品，有效避免缝包袋、卷口方底袋密封不严灌装粉状、小颗粒状等物品出现泄漏；避免外界湿度对袋内物品的影响。The structure of the present invention has excellent airtightness, which is better than that of sewing bags and roll-top square bottom bags. Leakage of granular and other items; avoid the influence of external humidity on the items in the bag.
本发明揭示了一种梯形袋，通过将袋子本体的底部封口和顶部封口设计成上下错开的梯形结构，使得其灌装后仍呈长方体，且底部封合平整，图案排布融为一体，无脱节，印刷能一次完成，外观设计美观，还能提高底向拉力，使其封合牢固，不易受外界湿度影响。The invention discloses a trapezoidal bag.
