Description

Technical Field

[0001] This utility model belongs to the field of packaging bag technology, and specifically relates to a granule packaging bag with a bag mouth extender. Background Technology

[0002] In today's production, storage, and sales processes, the rationality of packaging bag design has a crucial impact on product quality protection, logistics, and consumer convenience. As the "outer garment" of a product, packaging bags are widely used in various fields such as food, daily necessities, and industrial raw materials, and their performance directly affects the product's market competitiveness. Currently, the design of most packaging bags on the market is relatively traditional, with a prominent problem: the length of the discharge port is fixed, making it impossible to flexibly adjust according to actual usage scenarios. This design mainly stems from the limitations of traditional packaging concepts and manufacturing processes. From a manufacturing perspective, the production process of packaging bags with fixed discharge port lengths is mature and simple, enabling large-scale, standardized, and efficient production. For example, common plastic film packaging bags can quickly complete forming and heat-sealing processes on production lines, resulting in lower production costs and suitability for mass production of various product packaging. Simultaneously, in the product packaging filling stage, a fixed-length discharge port facilitates precise docking with automated packaging equipment, improving the efficiency and stability of packaging operations.

[0003] However, the drawbacks of a fixed spout length are more pronounced when pouring contents. For granular or powdery items, such as rice or laundry detergent, a shorter spout can cause the material to scatter at the container opening when poured into bottles or cans, making it difficult to accurately control the amount poured into the container. This inconvenience is particularly pronounced in scenarios requiring precise measurements, such as adding seasonings during cooking.

[0004] Therefore, this application provides a granule packaging bag with a bag opening extender, which is designed to allow users to flexibly adjust the position of the bag opening, thereby improving the convenience of pouring out the contents and bringing consumers a better user experience. Utility Model Content

[0005] This invention provides a granule packaging bag with a bag opening extender, which aims to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A granule packaging bag with a bag mouth extender includes: a packaging bag body, wherein a discharge nozzle is provided on the upper part of the packaging bag body;

[0008] The discharge nozzle includes: a fixed tube fixedly connected to the packaging bag body, a telescopic tube slidably connected to the middle of the fixed tube, and a cap threadedly connected to the upper end of the telescopic tube;

[0009] The upper part of the fixed tube is a regular hexagonal clamping tube, and the lower part is a round tube. The upper part of the telescopic tube is provided with a hexagonal receiving cavity that mates with the clamping tube. The outer side wall of the clamping tube is provided with a clamping flange, and the hexagonal receiving cavity is provided with a clamping groove that mates with the clamping flange.

[0010] Furthermore, the inner wall of the fixed tube is provided with a plurality of elastic sealing rings, and the upper and lower parts of the outer wall of the telescopic tube are respectively provided with sealing grooves for cooperating with the elastic sealing rings.

[0011] When the upper sealing groove engages with the elastic sealing ring, the telescopic tube is located at the lower limit position; when the lower sealing groove engages with the elastic sealing ring, the telescopic tube is located at the upper limit position.

[0012] Furthermore, the lower end of the telescopic tube is provided with a limiting flange, which cooperates with the lower end of the fixed tube to prevent the telescopic tube from falling out of the fixed tube.

[0013] Furthermore, a limiting cavity is provided at the lower part of the fixed tube, which is used to accommodate the limiting flange.

[0014] Furthermore, the middle part of the packaging bag body is a storage cavity, and the edge of the packaging bag body is provided with a bag body seal and a discharge nozzle seal, and the discharge nozzle seal cooperates with the round tube part of the fixed tube in the discharge nozzle.

[0015] Furthermore, a grip opening is provided at the top of the packaging bag body.

[0016] Furthermore, the edge of the grip opening is provided with a flexible pad.

[0017] Compared with the prior art, the present invention has the following technical effects:

[0018] 1. The granule packaging bag with a bag mouth extender described in this utility model features a design where a telescopic tube and a fixed tube are slidably connected, allowing the length of the discharge nozzle to be flexibly adjusted according to actual needs. When granule material needs to be poured into a deeper container, the telescopic tube can be pulled out from the fixed tube to extend the length of the discharge nozzle, allowing the granules to fall directly into the bottom of the container, preventing granules from spilling during pouring and improving the accuracy and efficiency of pouring.

[0019] 2. The granule packaging bag with a bag mouth extender described in this utility model has a cap threadedly connected to the upper end of the telescopic tube. When the packaging bag is not in use, the cap can be tightened to effectively prevent the granule material from getting damp, contaminated, or leaking. The threaded connection of the cap provides a good sealing effect, ensuring that the quality of the granule material inside the packaging bag is not affected by the external environment, thus extending the shelf life of the material.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to specific embodiments of this application and the accompanying drawings.

[0029] like Figure 1 and Figure 3-4 As shown, a granule packaging bag with a bag mouth extender includes: a packaging bag body 1, wherein a discharge nozzle 2 is provided on the upper part of the packaging bag body 1;

[0030] The discharge nozzle 2 includes: a fixed tube 201 fixedly connected to the packaging bag body 1, a telescopic tube 202 slidably connected to the middle part of the fixed tube 201, and a cap 203 threadedly connected to the upper end of the telescopic tube 202.

[0031] The upper part of the fixed tube 201 is a regular hexagonal clamping tube, and the lower part is a round tube. The upper part of the telescopic tube 202 is provided with a hexagonal receiving cavity 205 that cooperates with the clamping tube. The outer side wall of the clamping tube is provided with a clamping flange 204. The hexagonal receiving cavity 205 is provided with a clamping groove 206 that cooperates with the clamping flange 204.

[0032] The design of the sliding connection between the telescopic tube 202 and the fixed tube 201 allows the length of the discharge nozzle 2 to be flexibly adjusted according to actual needs. When it is necessary to pour granular materials into a deeper container, the telescopic tube 202 can be pulled out from the fixed tube to extend the length of the discharge nozzle 2, so that the granules can fall directly into the bottom of the container, avoiding spillage during the pouring process and improving the accuracy and efficiency of pouring.

[0033] When the telescopic tube 202 retracts, the locking tube engages with the hexagonal receiving cavity 205, restricting rotation between the telescopic tube 202 and the fixed tube 201, facilitating the tightening of the cap 203 at the end of the telescopic tube 202. The engagement of the locking flange 204 and the locking groove 206 provides a fixing function between the telescopic tube 202 and the fixed tube 201, preventing the telescopic tube 202 from slipping out of the fixed tube 201 when not in use.

[0034] like Figure 3 As shown, a plurality of elastic sealing rings 207 are provided on the inner cavity sidewall of the fixed tube 201, and the upper and lower parts of the outer sidewall of the telescopic tube 202 are respectively provided with sealing grooves 208 for cooperating with the elastic sealing rings 207.

[0035] When the upper sealing groove 208 is engaged with the elastic sealing ring 207, the telescopic tube 202 is located at the lower limit position; when the lower sealing groove 208 is engaged with the elastic sealing ring 207, the telescopic tube 202 is located at the upper limit position.

[0036] An elastic sealing ring 207 is provided on the inner wall of the fixed tube 201, and a sealing groove 208 is provided on the outer wall of the telescopic tube 202. When the telescopic tube 202 is in different positions (upper limit position and lower limit position), the elastic sealing ring 207 can be tightly embedded in the sealing groove 208. This design can effectively prevent particulate materials in the packaging bag from leaking out from the connection gap between the telescopic tube and the fixed tube.

[0037] When the telescopic tube 202 reaches its upper or lower limit position, the tight fit between the elastic sealing ring 207 and the sealing groove 208 ensures that the telescopic tube remains relatively stable in that position. When pouring granular materials, the telescopic tube 202 will not easily change position due to external forces, ensuring the stability and reliability of the discharge process and helping to improve the accuracy and efficiency of discharge. During the extension and retraction of the telescopic tube 202, when the elastic sealing ring 207 enters or disengages from the sealing groove 208, the user will feel a certain change in resistance. This change in resistance serves as operational feedback, allowing the user to more intuitively understand the positional status of the telescopic tube 202.

[0038] like Figure 3 As shown, the lower end of the telescopic tube 202 is provided with a limiting flange 209, which cooperates with the lower end of the fixed tube 201 to prevent the telescopic tube 202 from falling out of the fixed tube 201.

[0039] like Figure 3 As shown, a limiting cavity 210 is provided at the lower part of the fixed tube 201, and the limiting cavity 210 is used to accommodate the limiting flange 209.

[0040] The limiting flange 209 at the lower end of the telescopic tube 202 cooperates with the lower end of the fixed tube 201 to effectively prevent the telescopic tube 202 from falling out of the fixed tube 201. During normal use, the packaging bag may undergo various operations, such as stretching, shaking, and squeezing. Without the limiting structure, the telescopic tube 202 may separate from the fixed tube due to excessive stretching, causing the bag opening extension function to fail and affecting the normal use of the product. The presence of the limiting flange 209 ensures that the telescopic tube 202 and the fixed tube 201 always remain connected, maintaining the integrity of the packaging bag structure. When the telescopic tube 202 retracts, the limiting flange 209 enters the limiting receiving cavity 210, allowing the telescopic tube 202 and the fixed tube 201 to fit tightly together, preventing any residue of the packaging bag contents from being unable to be poured out.

[0041] like Figure 2 As shown, the middle part of the packaging bag body 1 is a storage cavity 101, and the edge of the packaging bag body 1 is provided with a bag body sealing edge 102 and a discharge nozzle sealing edge 103. The discharge nozzle sealing edge 103 cooperates with the round tube part of the fixed tube 201 in the discharge nozzle 1.

[0042] like Figure 1-2 As shown, the upper part of the packaging bag body 1 has a grip opening.

[0043] like Figure 1 As shown, a flexible pad 3 is provided on the edge of the grip opening.

[0044] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present utility model, and these all fall within the protection scope of the present utility model.
