DETAILED DESCRIPTION

[0020] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0021] To solve the problem that the film is broken after the existing cream outlet end, and the film scraps are discharged with the medicine when the cream tube is squeezed, please refer to Figures 1-4 The utility model discloses a gel cream extrusion nozzle, can be in the cream storage tube sleeve nozzle at the same time, resist broken film. The cream extrusion nozzle has the cap 2 for closing the cream tube 1 export, the cream tube 1 is rotatably sleeved with the lead-out assembly 3, and the cream tube 1 includes a storage portion 101 and a tube head portion 102 connected with the opening end of the storage portion 101. The tube head portion 102 is connected with a sealing film 103. When the whole gel cream is not split, the cap 2 is sleeved on the outlet end of the cream tube 1. Conversely, when the gel cream needs to be split for use, the cap 2 is rotated and removed from the tube opening of the cream tube 1, and then the other end of the cap 2 is aligned with the sealing film 103 on the tube head portion 102 of the cream tube 1, and the sealing film 103 is pierced by extrusion. Then, the lead-out assembly 3 is detachably sleeved on the outer surface of the tube head portion 102 of the cream tube 1, and at the same time of sleeving, the pierced sealing film 103 is pressed against the inner wall of the tube head portion 102, thereby effectively avoiding affecting the discharge rate of the medicine.

[0022] Specifically, the lead-out assembly 3 includes an extended nozzle 301 detachably connected to the cream tube 1. The inner wall of the extended nozzle 301 is provided with a pressing structure 302 that presses the broken sealing film 103 to the inner wall of the tube head portion 102 after being connected with the cream tube 1. The groove formed between the pressing structure 302 and the extended nozzle 301 has a width greater than the wall thickness of the tube head portion 102. As described above, when the extended nozzle 301 is sleeved on the outer surface of the tube head portion 102, the pressing structure 302 is correspondingly pushed inward along the inside of the tube head portion 102. In this way, the broken sealing film 103 is gradually adjusted from a nearly planar state to a state of being attached to the inner wall of the tube head portion 102, thereby effectively avoiding its influence on the discharge rate of the medicine, and avoiding its discharge into the patient's body along with the medicine.

[0023] As Figure 1 and Figure 3As shown, the pressing structure 302 comprises a pressing ring 3021 connected to the inner wall of the extended nozzle 301, and the inner diameter of the pressing ring 3021 is smaller than the inner diameter of the tube head part 102. The extended ring 3022 is mounted on the groove part of the inner wall of the pressing ring 3021, and the difference between the outer diameter of the extended ring 3022 and the inner diameter of the tube head part 102 is adapted to the thickness of the sealing film 103, so as to provide sufficient space for the sealing film 103 to be pierced to fit the inner wall of the tube head part 102.

[0024] As described above, due to the gap between the extended ring 3022 and the tube head part 102, part of the cream will enter the gap when the cream tube 1 is squeezed, affecting the discharge of the cream. In order to solve this problem, as shown in the figure, Figure 3 The silicone ring 3023 is connected to the end of the extended ring 3022 away from the pressing ring 3021, and the side surface of one end of the silicone ring 3023 is seamlessly fitted with the inner wall of the tube head part 102. The inner diameter and the outer diameter of the silicone ring 3023 gradually decrease from one side to the other side away from the extended ring 3022. The inclined angle of the inner wall of the extended ring 3022 is consistent with that of the silicone ring 3023, and the inner wall diameter of the pressing ring 3021 is consistent with the diameter of the smallest part inside the extended ring 3022. The silicone ring 3023 itself has a certain elasticity, and its own shape can change slightly during the process of penetrating the sealing film 103. After penetrating, the side surface of one end of the silicone ring 3023 returns to the state of seamlessly fitting with the inner wall of the tube head part 102, thereby sealing the gap between the extended ring 3022 and the tube head part 102, effectively preventing the cream from entering the gap when being squeezed out. In addition, the silicone ring 3023 and the extended ring 3022 with inclined inner wall form a transition between the cream tube 1 and the extended nozzle 301, and the smooth inner wall facilitates the flow of the cream.

[0025] As shown in the figure, Figure 4 The extended nozzle 301 is composed of a connecting section 3011, an arc transition section 3012 connected to the connecting section 3011, and a tapered tube section 3013 connected to one end of the arc transition section 3012. The entire surface of the extended nozzle 301 is smooth without burrs, and the head part is arranged in an arc shape without burrs. The outer surface is provided with wavy anti-skid corrugations, which facilitates rotation, disassembly and assembly. The inner surface is provided with internal threads matched with the external threads of the cream tube 1, and the injection port is arranged in the vertical rib groove.

[0026] As shown in the figure, Figure 2As shown, one side of the cap 2 is provided with a spiral groove 201, and the inner diameter of the spiral groove 201 is consistent with the outer diameter of the pipe head part 102, and the other side of the cap 2 is provided with a notch 202, and the inner wall of the notch 202 is provided with a spike 203. The cap 2 is in a structure close to a cone, and the surface is also provided with a wavy anti-skid corrugation, which is convenient for rotating, disassembling and assembling, and at the same time, the arc transition has no dead angle, which is convenient for cleaning and sterilization. In addition, the spike 203 is in a conical shape, which is used for opening the sealing film 103 of the ointment tube 1, and the diameter of the spike 203 is (6.5-7.5) mm.
