Each compartment has a pocket 33; the mouth 33 is sealed by a sealing cap. The mouth 33 of the present embodiment is a hard mouth 33, such as a mineral water bottle mouth, which is screw-sealed with a sealing cap 33'. In order to achieve the sealing property of the partition surface 32 and the destructibility of the shallow connecting line, the partition surface 32 may be made of the same material as that of the bag body 31.

The plurality of compartments are filled with components with different properties, and during construction, the components of the plurality of compartments need to be mixed to form the components for construction. In order to mix the glue, the shallow connecting line 34 is arranged on the partition surface 32; the shallow lines 34 rupture upon pressure or lateral pulling from the cells on either side of the partition 32, allowing conduction between the cells on either side of the partition 32. Shallow interconnects 34 may be pressed to a depth 1/2-2/3 the thickness of septum 32, to facilitate fracture prior to sealing. The shallow lines 34 may be in the shape of a cross, or a cross or a circular arc, as shown in fig. 21 and 22.

Principle of operation

The respective compartments are filled with respective components, which may be in liquid, powder, gel, etc., through the bag opening 33, and then sealed and fixed. Before construction, the two sides of the bag body 31 are manually pulled or the compartments on one side are manually squeezed, so that the partition surface 32 is pulled or squeezed, the shallow connecting line 34 is broken, and the compartments on the two sides of the partition surface 32 are communicated.

Example 2

As shown in fig. 23, in this embodiment, sheet-like hand-breakable portions 35 are added to both sides of the partition surface 32 in order to facilitate breaking of the shallow connecting line 34, and the hand-breakable portions 35 may be soft or hard, and may be fixed to the bag body 31 so as to be flush with the partition surface 32. When the two manual breaking parts 35 are pulled, the partition surface 32 is pulled at two sides, and the shallow connecting line 34 is broken, so that the compartments at two sides of the partition surface 32 are communicated.

Example 3

As shown in fig. 24, unlike embodiment 2, the manual breaking portion 35 may be a plate-like structure annularly disposed around the partition surface 32, and is coplanar with the partition surface 32, so as to facilitate pulling from different directions to promote the overall rupture of the cross-shaped or crisscross-shaped shallow connecting line 34.

Example 4

As shown in fig. 25, 26 and 27, the present embodiment is different from embodiments 1 to 3 in that the partition surface 32 has a double-layer structure, the double-layer structure is a bag-shaped structure, the bag bottom is connected with the inner wall of the bag body 31 through a connecting sheet 36, and the bag mouth 33 is respectively sealed and fixed with the bag body 31; the bag body 31 is provided with a drawing opening 311 at the bag opening 33; shallow lines 34 are pressed on the connecting sheets 36, and the shallow lines 34 are pulled to be torn by a pulling strip 37. The drawing strip 37 extends from the bottom of the bag to the mouth 33, and penetrates through the drawing opening 311 on the bag body 31, the drawing strip 37 is pulled, the connecting sheet 36 is broken along the shallow connecting line 34, and the two side compartments are communicated.

The size of the drawing opening 311 is set according to the requirement, and generally only enough drawing strip 37 is needed to be pulled out, which is not easy to be too large, especially the boundary of the drawing opening 311 is not easy to be set at the corner of the bag body 31 (the cross section of the bag body 31 is generally square or rectangular) to reduce the stress concentration to cause the bag body 31 to break.

The end surface of the bag opening 33 is in arc transition with the side edge of the partition surface 32, so that stress concentration is reduced.

The driving mechanism 4:

as shown in fig. 28 and 29, the driving mechanism includes a housing 41, the interior of the housing 41 is divided into a pressurizing chamber 411 and a power chamber 412 by a partition 42, the glue mixing bag 3 is placed in the pressurizing chamber 411, and a power part 413 is fixed in the power chamber 412; the pressurizing bin 411 is provided with a glue outlet 415 for extending the bag opening; a cover cap 241 at the glue inlet end of the glue delivery pipe 24 is in threaded connection with the bag opening 33 through a glue outlet 415, and a rear pressurizing bin 411 is connected to form a sealing cavity; the partition 42 is provided with an air hole 414, an air pump 413 is fixed in the power bin 412, and the air pump 413 supplies air to the pressurizing bin 411 through the air hole 414 for pressurization. A pressure sensor may be disposed in the pressurizing chamber 411 to realize real-time adjustment of the air pump 413 according to the current pressure detected by the pressure sensor. By matching the glue mixing bag 3 with the air pump 413, glue can be evenly discharged according to multi-component liquid or glue with different viscosities.
