Description

Technical Field

[0001] The invention relates to the technical field of aqueous solution packaging bags, in particular to a high-barrier pesticide emulsifiable concentrate aqueous solution packaging bag. Background Art

[0002] Emulsifiable concentrate is a type of pesticide formulation. It is a liquid made by dissolving a relatively high concentration of active ingredients in a solvent and adding an emulsifier. It is usually diluted with a large amount of water to form a stable emulsion and then sprayed with a sprayer. Recently, low-volume spraying and even ultra-low-volume spraying are also used. Emulsifiers are mostly mixtures of non-ionic and anionic surfactants, and solvents are mostly petroleum solvents such as xylene and methylnaphthalene. In addition, alcohol solvents such as methyl isobutyl ketone and isopropyl alcohol are also used.

[0027] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0028] The following describes an embodiment of the present invention based on its overall structure.

[0029] A high barrier pesticide emulsifiable concentrate aqueous solution packaging bag, such as Figures 1 to 7 As shown, it includes an outer shell 1, and the outer shell 1 includes a protective shell 101. The internal sliding sleeve of the protective shell 101 is provided with an inner ring 102, and the inner wall of the inner ring 102 is rotatably connected to multiple groups of extrusion rollers 103. The inner wall sliding sleeve of the protective shell 101 is provided with an outer ring 104, and the outer wall of the protective shell 101 is fixedly connected to multiple groups of limiting teeth 105. The inner wall of the outer ring 104 is slidably connected to a limiting pin 106, and the limiting pin 106 abuts against the outer wall of a group of limiting teeth 105. The side wall of the limiting pin 106 is fixedly connected to two groups of spring sheets 107, and the end of the spring sheet 107 is fixedly connected to the inner wall of the outer ring 104. The outer wall of each group of extrusion rollers 103 is respectively fixedly connected to multiple groups of convex strips.

[0030] The outer ring 104 is pushed so that the outer ring 104 drives the inner ring 102 to slide upward, and the inner ring 102 drives the squeezing roller 103 to move during the upward sliding process. In the process of the squeezing roller 103 moving upward, the convex strips on the outer wall of the squeezing roller 103 fit with the lower seal 202, so that the squeezing roller 103 rolls on the outer wall of the lower seal 202. As the squeezing roller 103 moves upward, the multiple groups of squeezing rollers 103 squeeze the polymer soft liner 201, so that the pesticide emulsifiable concentrate inside the polymer soft liner 201 When the outer ring 104 drives the inner ring 102 to slide upward, the outer ring 104 drives the limit pin 106 to move upward, so that the limit pin 106 is pushed by a group of limit teeth 105, so that the limit pin 106 slides toward the inner wall of the outer ring 104 and compresses the elastic sheet. After the outer ring 104 stops pushing, the rebound force of the spring sheet 107 causes the limit pin 106 to slide back and reset, so that the limit pin 106 is blocked by the limit teeth 105 again, thereby preventing the outer ring 104 from being accidentally pushed during storage.

[0031] Please refer to Figure 2 , Figure 3, Figure 4 , Figure 5 and Figure 6 The bottom end of the protective shell 101 is provided with an inner bag body 2, and the inner bag body 2 includes a sleeve 204, and the sleeve 204 is sleeved on the inner wall of the protective shell 101 near the top, and the sleeve 204 and the protective shell 101 are limited by interference fitting. The inner wall of the sleeve 204 is sleeved with an upper seal, and the bottom end of the upper seal is fixedly connected with a polymer soft liner 201, and the top of the upper seal is provided with multiple groups of discharge ports 203, and the bottom end of the polymer soft liner 201 is fixedly connected with a lower seal 202, and the lower seal 202 extends between multiple groups of extrusion rollers 103, and the lower seal 202 is attached to the outer wall of multiple groups of convex strips. The inner wall of the sleeve 204 A plurality of groups of pointed cones 205 are fixedly connected, and a through hole 206 is provided at the connection between the sleeve 204 and the pointed cone 205, and the through hole 206 is communicated with the discharge port 203. An upper cover 207 is slidably sleeved on the inner wall of the sleeve 204, and a plurality of groups of silicone sheets 208 are fixedly connected to the top of the upper cover 207, and a protective cover 211 is slidably sleeved on the outer wall of the upper cover 207. A small hole is provided on the top of the silicone sheet 208, and the small hole is sleeved on the outer wall of the pointed cone 205. A plurality of groups of elastic protrusions 209 are fixedly connected to the inner bottom end of the sleeve 204, and a plurality of groups of grooves 210 are provided on the inner wall of the upper cover 207, and the inner wall of the groove 210 matches the end of the elastic protrusion 209.

[0032] Before squeezing out the pesticide emulsifiable concentrate, remove the protective cover 211 and push the upper cover 207, so that the upper cover 207 drives the silicone sheet 208 to move downward, so that the pointed cone 205 passes through the small hole on the silicone sheet 208, so that the small hole is opened by the pointed cone 205, and the groove 210 is driven to move during the downward sliding of the upper cover 207. When the upper cover 207 contacts the elastic protrusion 209, it pushes the elastic protrusion 209 until the elastic protrusion 209 is aligned with the groove 210, and the elastic protrusion 209 rebounds and embeds into the groove 210. In the process of squeezing out the pesticide emulsifiable concentrate in the polymer soft liner 201, the upper cover 207 is subjected to a certain degree of pressure, and the groove 210 is used to limit the elastic protrusion 209 to a certain extent, so that when there is no When manually pulled, the upper cover 207 will not rebound automatically. After the required amount of pesticide emulsifiable concentrate is squeezed out, the upper cover 207 is pulled to retract the pointed cone 205. At this time, the silicone sheet 208 rebounds, so that the small holes on the silicone sheet 208 are sealed under the elasticity of the silicone sheet 208 itself, and then the protective cover 211 is covered back on the outside of the upper cover 207 again, thereby completing the extrusion operation of the pesticide emulsifiable concentrate, and the sleeve 204 and the protective shell 101 are assembled together by interference fit, so that after the pesticide emulsifiable concentrate inside the polymer soft liner 201 is used up, the sleeve 204 can be pulled out, and then the polymer soft liner 201 filled with pesticide emulsifiable concentrate and the sleeve 204 connected thereto are fixed inside the protective shell 101.

[0033] When in use, the outer ring 104 is pushed so that the outer ring 104 drives the inner ring 102 to slide, so that multiple groups of extrusion rollers 103 extrude the polymer soft liner 201, so that the pesticide emulsifiable concentrate inside the polymer soft liner 201 is squeezed out, and the limiting pin 106 is limited by multiple groups of limiting teeth 105, so that when the pesticide emulsifiable concentrate is extruded, the amount of the extruded pesticide emulsifiable concentrate can be freely controlled according to the area of ​​the pesticide spraying, thereby avoiding waste in the process of spraying pesticides.
