Description

Technical Field

[0001] This utility model relates to an aluminum tube for packaging, and more particularly to an aluminum tube with a nozzle. Background Technology

[0002] Currently, silicone sealant is mainly packaged in plastic bottles or plastic bags. The plastic bottles are tubular, with a dispensing port at one end and a stopper at the other. They require a caulking gun for use. To use, the dispensing port is screwed with an injection nozzle, and the caulking gun is used to push against the stopper, expelling the silicone sealant from the bottle. The plastic bags are elongated, with a dispensing port at one end and a closed end. To use, the dispensing port is screwed with an injection nozzle, and the entire bag of silicone sealant is placed into the barrel of a sleeve-type caulking gun and squeezed out.

[0003] In summary, the aforementioned silicone sealant containers need to be used with a caulking gun, and the sealant capacity is relatively large. If only a small amount of sealant is needed in the application, the user will need to provide a caulking gun. Furthermore, after using a small amount of sealant, the unused sealant is prone to failure, resulting in significant waste. Utility Model Content

[0004] The purpose of this invention is to provide an aluminum tube with a nozzle that has a simple and reasonable structure and is easy to use.

[0005] The purpose of this utility model is achieved as follows: An aluminum tube with a nozzle includes an aluminum tube body and a plastic cap. The aluminum tube body includes a tube body, a tube shoulder, and a nozzle from bottom to top. The nozzle is a spray nozzle with a length greater than 2 cm. The nozzle has an internal spray channel. The walls of the spray channel and the nozzle are both tapered, wider at the bottom and narrower at the top. The outer periphery of the nozzle is also provided with connecting threads, the lower end of which is separated from the tube shoulder. The plastic cap has a double-layer structure. The inner layer covers the nozzle and is threadedly connected to the nozzle. The lower end of the plastic cap is suspended above the tube shoulder. The inner top surface of the plastic cap protrudes downward with a conical or spherical plug that abuts against the edge of the nozzle's outlet.

[0006] The objective of this utility model can also be achieved by the following technical measures: As a more specific embodiment, the wall thickness of the nozzle is greater than the wall thickness of the shoulder, and the wall thickness of the shoulder is greater than the wall thickness of the body.

[0007] As a further option, the nozzle has a wall thickness of 1-2mm and an outlet diameter of 2-8mm, which can meet the general injection requirements for glass glue.

[0008] As a further embodiment, the inner layer of the plastic cap includes a threaded sleeve and a top cover. The threaded sleeve is straight and has an internal thread on its inner wall that is threaded to the nozzle. The top cover is located at the upper end of the threaded sleeve, and the plug is located on the inner top surface of the top cover. A partition is provided on the outer periphery of the connection between the threaded sleeve and the top cover. An outer layer is provided on the outer periphery of the partition. The upper part of the outer layer is separated from the top cover to form an upper interlayer, and the lower part of the outer layer is separated from the threaded sleeve to form a lower interlayer.

[0009] As a further solution, the inner top surface of the upper cover is provided with a protruding ring corresponding to the outer periphery of the plug, and the protruding ring abuts against the top surface of the nozzle to play a secondary sealing role.

[0010] As a further solution, the lower end of the outer layer is lower than the bottom surface of the threaded sleeve to prevent the threaded sleeve from being exposed and to improve aesthetics.

[0011] As a further embodiment, the upper end of the outer layer is higher than the top surface of the upper cover.

[0012] As a further solution, the upper interlayer is also provided with reinforcing ribs, which improves the rigidity of the outer layer and the upper cover and prevents them from being crushed and deformed.

[0013] As a further improvement, the outer surface of the plastic cover is provided with anti-slip texture.

[0014] As a further solution, the outer diameter of the upper interlayer is smaller than the outer diameter of the lower interlayer, and the inner diameter of the lower interlayer is smaller than the outer diameter of the upper interlayer; this achieves a certain misalignment between the upper and lower interlayers, and combined with the function of the partition, makes the plastic cover more resistant to torsion.

[0015] The beneficial effects of this utility model are as follows: The aluminum tube body of this utility model is mainly used for encapsulating glass glue. It is equipped with a nozzle, which, together with the extrusion of the tube body, can extrude the glass glue. The plastic cap adopts a double-layer structure with a larger outer diameter, which generates greater torque when rotated, so as to tighten it and ensure that the plug and the discharge edge of the nozzle are tightly abutted to prevent air from entering.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments: See Figures 1 to 5 As shown, an aluminum tube with a nozzle includes an aluminum tube body 1 and a plastic cap 2. The aluminum tube body 1 includes a tube body 11, a tube shoulder 12 and a nozzle from bottom to top. The nozzle is a nozzle 13 with a length greater than 2 cm. The nozzle 13 has a material injection channel 15 inside. The walls of the material injection channel 15 and the nozzle 13 are both conical with a wider bottom and a narrower top. The outer periphery of the nozzle 13 is also provided with a connecting thread 14, the lower end of which is separated from the tube shoulder 12. The plastic cap 2 has a double-layer structure. Its inner layer covers the nozzle 13 and is threadedly connected to the nozzle 13. The lower end of the plastic cap 2 is suspended above the tube shoulder 12. The inner top surface of the plastic cap 2 protrudes downward with a conical or spherical plug 28, which abuts against the edge of the discharge port 151 of the nozzle 13.

[0022] The wall thickness of the nozzle 13 is greater than the wall thickness of the shoulder 12, and the wall thickness of the shoulder 12 is greater than the wall thickness of the body 11.

[0023] The nozzle 13 has a wall thickness of 1-2 mm and a discharge port 151 diameter of 2-8 mm.

[0024] The inner layer of the plastic cover 2 includes a threaded sleeve 22 and an upper cover 23. The threaded sleeve 22 is straight and has an internal thread that is threaded to the connecting thread 14 of the nozzle 13. The upper cover 23 is located at the upper end of the threaded sleeve 22, and the plug 28 is located on the inner top surface of the upper cover 23. A partition 24 is provided on the outer periphery of the connection between the threaded sleeve 22 and the upper cover 23. An outer layer 21 is provided on the outer periphery of the partition 24. The upper part of the outer layer 21 is separated from the upper cover 23 to form an upper interlayer 26, and the lower part of the outer layer 21 is separated from the threaded sleeve 22 to form a lower interlayer 25.

[0025] The inner top surface of the upper cover 23 is provided with a protruding ring 29 corresponding to the outer periphery of the plug 28, and the protruding ring 29 abuts against the top surface of the nozzle 13.

[0026] The lower end of the outer layer 21 is lower than the bottom surface of the threaded sleeve 22.

[0027] The upper end of the outer layer 21 is higher than the top surface of the upper cover 23.

[0028] The upper interlayer 26 is also provided with reinforcing ribs 27.

[0029] The outer surface of the outer layer 21 of the plastic cover 2 is provided with anti-slip texture 211.

[0030] The outer diameter of the upper interlayer 26 is smaller than the outer diameter of the lower interlayer 25, and the inner diameter of the lower interlayer 25 is smaller than the outer diameter of the upper interlayer 26.

[0031] The aforementioned aluminum tube is mainly used for sealing with silicone sealant (when sealing with silicone sealant, the tail of the tube body 11 is folded and pressed tightly to seal). Since the aluminum tube does not automatically return to its original position after being extruded (unlike plastic extrusion tubes), it avoids the formation of negative pressure and the intake of air during material recovery deformation, thus preventing the oxidation of the remaining silicone sealant. The plastic cap 2 adopts a double-layer structure, increasing its outer diameter and facilitating tightening. After tightening, the plug in the plastic cap fits tightly with the nozzle outlet, and the convex ring also fits tightly with the top surface of the nozzle, achieving a double seal.

[0032] The above describes the preferred embodiments of this utility model, illustrating and describing its basic principles, main features, and advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made without departing from the spirit and scope of this utility model, and all such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
