Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging bags, and in particular to a bag structure with a spout and a handle. Background Technology
[0002] Currently, most powder packaging bags on the market are made of PET / NY / PE or PET / PE material, which is relatively soft and has poor upright performance. Due to the rigidity of the material, the powder dispensing amount is difficult to control, and the bags tend to collapse after opening, making them difficult to store. This is especially true for tall, narrow stand-up pouches, gusseted pouches, and three-side seal bags, which are prone to collapsing after opening. Furthermore, ordinary stand-up pouches and spouted stand-up pouches, due to their material properties and lack of a good gripping point, make it difficult to accurately control the amount of product dispensed during use. Utility Model Content
[0003] To address the shortcomings of existing powder packaging bags, such as easy collapse, deformation during tipping, and difficulty in controlling the amount of powder used, this invention proposes a bag structure with a spout and handle, which provides stability when unfolded, prevents collapse and deformation, and facilitates control over the amount of powder poured.
[0004] This utility model proposes a bag structure with a spout and handle, comprising: a bag body, a spout, and a handle; the bag body, when laid flat, is a short and stout hexagonal structure, including a top edge, a bottom edge, a left diagonal edge, a right diagonal edge, a left vertical edge, and a right vertical edge; the top edge and the bottom edge are parallel and opposite to each other, and the left vertical edge and the right vertical edge are parallel and opposite to each other and perpendicularly connected at opposite ends of the bottom edge; the left diagonal edge is connected between the left vertical edge and the top edge; the right diagonal edge is connected between the right vertical edge and the top edge; the spout is located on the left diagonal edge, and the handle is located on the right diagonal edge.

[0010] Preferably, the angle between the left hypotenuse and the left vertical side is 30°, and the angle between the right hypotenuse and the right vertical side is 30°.
[0011] Preferably, the bottom end of the bag mouth outlet plane is located on the extension line of the left vertical side.

[0014] The advantages of this utility model are:
[0015] 1) The bag structure with added spout and handle proposed in this utility model improves the appearance of the current tall and thin stand-up pouches and makes them into short and stout stand-up pouches, which can effectively solve the problem of the product collapsing after use.
[0016] 2) In this utility model, the angle design of the bag mouth and the side where the handle is located, combined with the short and stout structure of the bag body, ensures the three-dimensional state of the bag body at any angle, avoids the bag body from collapsing during the tipping process, and makes it easier and more convenient to carry.
[0017] 3) In this utility model, the amount of contents poured out can be controlled more precisely through the special inner diameter of the bag mouth, the hard handle and the special size design.

[0023] 2. Pocket opening; 3. Handle buckle; Detailed Implementation
[0024] This embodiment proposes a bag structure with a spout and handle, comprising: a bag body 1, a spout 2, and a handle 3. The bag body 1 has a planar structure when laid flat and a standing three-dimensional structure with a cavity when unfolded.
[0025] The bag body 1 has a hexagonal structure when laid flat, including a top edge 101, a bottom edge 102, a left diagonal edge 103, a right diagonal edge 104, a left vertical edge 105, and a right vertical edge 106. The top edge 101 and the bottom edge are parallel and opposite to each other. The left vertical edge 105 and the right vertical edge 106 are parallel and opposite to each other and are vertically connected at opposite ends of the bottom edge 102. The left diagonal edge 103 is connected between the left vertical edge 105 and the top edge 101. The right diagonal edge 104 is connected between the right vertical edge 106 and the top edge 101. The bag opening 2 is set on the left diagonal edge 103, and the handle 3 is set on the right diagonal edge 104.
[0026] Specifically, the length-to-width ratio of bag 1 is 1:1.37, giving it a short and stout shape. This allows bag 1 to stand upright whether empty or full of products, without easily collapsing.
[0027] In this embodiment, when the bag body 1 is unfolded, the bottom of its cavity consists of two symmetrical boat-shaped structures about the plane where the top edge 101 is located, with the two boat-shaped structures abutting each other and their bottoms far apart. This allows the product to easily fill the bottom corners of the bag body 1 when it is filled, preventing deformation of the bottom corner cavity and thus improving the stability of the bag body 1 when standing. In a specific implementation, the hexagonal structure of the bag body 1 in its flat state can also be designed to be bilaterally symmetrical to further improve its stability.
[0028] The handle 3 uses a 12g six-tooth handle, which can ensure the best lifting feel and withstand 10 drops from a height of 2 meters without opening. The spout 2 uses a cylindrical structure with an inner diameter of 26mm. After testing, this diameter spout has the highest powder output rate and the smallest inner diameter when used with contents weighing 1.5-4.0kg, making it the most cost-effective.
[0029] The angle between the left hypotenuse 103 and the left vertical side 105 is within the range [25°, 35°], and the angle between the right hypotenuse 104 and the right vertical side 106 is also within the range [25°, 35°]. Preferably, the angle between the left hypotenuse 103 and the left vertical side 105 is 30°, and the angle between the right hypotenuse 104 and the right vertical side 106 is also 30°. Testing showed that this angle is the most effortless to lift the entire bag and yields the highest powder output, reaching a maximum of 89%. This design, while saving effort, also allows for better control of powder output through the tilt angle of the handle 3, preventing the bag body 1 from collapsing or deforming due to the material's hardness. The entire force point for lifting the bag is concentrated at the rigid handle.
[0030] The bottom of the outlet plane of the spout 2 is located on the extension line of the left vertical side 105. Testing has shown that this design achieves a high powder discharge rate and ensures that excess powder does not clog the bottom of the spout.
[0031] The bottom of the bag body 1 is provided with multiple vent holes 107 that communicate with the cavity and have a diameter of less than or equal to 0.5 mm. The distance between the vent holes 107 is greater than or equal to 30 mm, and a total of 8 vent holes 107 can be provided. The arrangement of the vent holes 107 can ensure the air pressure balance inside and outside the bag and ensure the powder output rate.
[0032] In this embodiment, multiple deformation holes 108 are provided at the bottom of both sides of the bag body 1. The diameter of the deformation holes 108 is greater than or equal to 8 mm. When the bag body 1 is unfolded, the deformation holes 108 are distributed at the four corners of the bottom of the bag body 1 and are located on the outer side of the bottom plane of the cavity. The setting of the deformation holes 108 can ensure the flatness of the bottom plane of the bag body 1 when the bag body 1 is unfolded, thereby improving the stability of the bag body 1 when standing, and also helping to prevent the bottom of the bag body 1 from deforming and squeezing the cavity, causing powder residue.
[0033] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
