[0020] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention.

[0021] like Figure 1-4 As shown, a stand-up bag with a welded guide tube comprises:

[0022] The bag body 1 has a liquid containing cavity 13, and the bag body 1 is provided with a water outlet 12 connected to the liquid containing cavity 13;

[0023] The guide tube 3 is arranged at the water outlet 12. The guide tube 3 includes a first opening 31 and a second opening 35 facing the liquid containing chamber 13. A support ring 33 is arranged between the first opening 31 and the second opening 35. The support ring 33 is provided with reinforcing ribs 34 in a circumferential array. The reinforcing ribs 34 cooperate with the first opening 31 and the second opening 35.

[0024] Specifically, the solution cavity of the bag body 1 is used to store liquid, the guide tube 3 is placed at the water outlet 12, and the guide tube 3 is welded to the bag body 1 by a spot welding device. At the same time, the support ring 33 and the reinforcing ribs 34 provided on the guide tube 3 improve the fixing effect of the guide tube 3 and the bag body 1, and the reinforcing ribs 34 can be arranged in a circular manner or in a grid shape on the guide tube 3. If the bag body 1 is squeezed, the structure of the reinforcing ribs 34 improves the compressive strength of the guide tube 3 and reduces the situation where transition deformation makes it difficult to use. The guide tube 3 is made of PE plastic with a length of 15 mm and an inner diameter of 10 mm.

[0025] As an embodiment further provided by the present invention, an arc portion is provided on the reinforcing rib 34, and a first groove 341 is formed between two adjacent reinforcing ribs 34. The arc portion connects two adjacent first grooves 341 to improve the ventilation effect during welding. Ventilation grooves 36 are provided at the support ring 33 and the first opening 31. At least three venting grooves 36 are provided. When welding the guide tube 3, a gap will be generated between the guide tube 3 and the bag body 1 when the water outlet 12 is placed thereon. During welding, bubbles will be generated if the gas in the gap is not discharged. During welding, the gas in the first groove 341 will flow out from the venting groove 36 and be discharged from the first opening 31, thereby reducing the phenomenon of bubbles generated in the guide tube 3 during welding.

[0026] As a further embodiment of the present invention, the first opening 31 is provided with fitting grooves 311 in a circular array. When the bag body 1 and the guide tube 3 are welded, the arc grooves increase the fitting area between the first opening 31 and the bag body 1, further improving the fixing effect of the guide tube 3 and the bag body 1.

[0027] As an embodiment further provided by the present invention, the second opening 35 is provided with fan-shaped pieces 352 in a circular array, and second grooves 351 are provided between the fan-shaped pieces 352. The fan-shaped pieces 352 make the second opening 35 conical. When the guide tube 3 is installed in the bag body 1, since there is a second groove 351 between the two fan-shaped pieces 352, the fan-shaped pieces 352 are expanded outward to exert a certain squeezing force on the bag body 1, so that the guide tube 3 is more closely attached to the water outlet 12, and the second groove 351 improves the flow efficiency of the solution when the solution is poured.

[0028] As a further embodiment of the present invention, a tear strip 11 is provided on the bag body 1, and the tear strip 11 is provided at the water outlet 12. When using the solution in the bag body 1, the tear strip 11 is held by hand to separate one corner from the bag body 1, so that the water outlet 12 is exposed.

[0029] As an embodiment further provided by the present invention, the liquid containing cavity 13 includes a triangular arc-shaped portion 131, and the bag body 1 is provided with a standing portion 2 that cooperates with the triangular arc-shaped portion 131. When the liquid containing cavity 13 is filled with solution, the weight of the liquid is applied to the standing portion 2 through the triangular arc-shaped portion 131, so that the bag body 1 stands more stably.

[0030] Working principle: a water outlet 12 is arranged at an oblique angle of the bag body 1, the guide tube 3 is inserted into the water outlet 12, the second outlet is directed toward the liquid containing chamber 13, and the oblique angle is spot-welded by a spot welding device, so that the guide tube 3 is welded to the inner surface of the water outlet 12. The temperature of the spot welding device is controlled at 180-200°C, the pressure is controlled at 0.6-0.8MPa, and the welding time is 1-2.5 seconds to ensure the firmness of the welding.

[0031] The technical solution of the above utility model provides a solution that is significantly different from the prior art to address the technical problem that the prior art solution is too single. The parts not involved in the technical solution of this application are the same as the prior art or can be implemented by using the prior art and will not be described in detail.

[0032] The technical solutions in the above embodiments have clearly and completely described the contents of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
