Description

Technical Field

[0001] This utility model relates to the field of flexible tube technology, specifically to a packaging flexible tube with an adjustable dispensing brush head. Background Technology

[0002] Packaging tubes are a common packaging material, widely used in various fields such as cosmetics, medical, and industry;

[0003] Existing packaging tubes mainly consist of three parts: the tube body (the main component), the tube itself, and the cap. The tube body is typically made of various materials, commonly plastics such as polyethylene (PE) and polypropylene (PP). These plastics offer good flexibility, facilitating compression. For example, polyethylene tubes are soft and suitable for packaging liquids with good flowability, such as shampoo and shower gel. Their flexibility allows consumers to easily squeeze the product out. Furthermore, the tube can be customized to different sizes according to the product's shape and capacity requirements during packaging. The nozzle is the channel through which the product is extruded and is usually equipped with a suitable cap. The shape and size of the nozzle are designed according to the product's nature and usage. For example, for paste-like products like toothpaste, the nozzle is relatively small and usually round, allowing for easy control of the extruded amount and preventing waste. For liquid products like hand sanitizer, the nozzle may be slightly larger to facilitate smooth liquid flow. The cap's main function is to seal the tube and prevent leakage.

[0004] However, when using this packaging tube for extrusion operations, it is difficult to control the amount of material extruded, which leads to waste if too much material is extruded. Therefore, it does not meet the existing needs. To address this, we propose a packaging tube with an adjustable discharge brush head. Utility Model Content

[0005] The purpose of this invention is to provide a packaging tube with an adjustable discharge brush head to solve the problems mentioned in the background art, such as the difficulty in controlling the amount of material extruded when using this packaging tube for extrusion operations, which would result in waste if too much material is extruded.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a packaging hose with an adjustable discharge brush head, comprising a packaging hose body, a hose thread head fixedly provided on the upper end face of the packaging hose body, a hose cap provided on the outer side of the hose thread head, an annular groove provided on the outer side of the upper end face of the hose cap, an external thread ring mounting groove provided on one side of the inner wall of the annular groove, an external thread ring fixedly provided inside the external thread ring mounting groove, an internal thread ring connected to the upper side of the outer surface of the external thread ring through a threaded structure, a transparent annular tube provided on the outer side of the internal thread ring, a scale fixedly provided on both the front and rear ends of the transparent annular tube, and a sealing cap covering the upper end face of the transparent annular tube.

[0007] Preferably, the lower end face of the hose cover is provided with an internal thread mounting groove at the middle position. The internal thread of the internal thread mounting groove matches the external thread of the hose thread head, and the hose cover is mounted on the outer surface of the hose thread head through the internal thread mounting groove.

[0008] Preferably, the transparent annular tube and the scale are both made of transparent plastic material in one piece, and the outer surface of the transparent annular tube is in contact with the inner wall of the annular groove.

[0009] Preferably, the threaded head of the hose is provided with a discharge port located in the middle of the inner wall of the upper end of the internal thread mounting groove, and the threaded head of the hose communicates with the interior of the transparent annular tube through the discharge port.

[0010] Preferably, a sealing filler plate located inside the transparent annular tube is fixedly provided on the inner side of the sealing cover. The outer surface of the sealing filler plate is in contact with the inner wall of the transparent annular tube. The sealing filler plate is slidably connected to the inner wall of the transparent annular tube, and the distance between the lower end face of the sealing filler plate and the discharge port is the same as the overall height of the scale.

[0011] Preferably, the outer side of the bottom end of the transparent annular tube is provided with an annular anti-detachment groove located on the inner wall of the annular groove, and the inside of the annular anti-detachment groove is provided with an anti-detachment ring sleeved on the outer surface of the transparent annular tube by a roller bearing, and the outer surface of the anti-detachment ring is in contact with the inner wall of the annular anti-detachment groove.

[0012] Preferably, a guide rod is fixedly provided at each of the four end corners inside the annular anti-detachment groove, and the guide rod moves vertically through the anti-detachment ring.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model features a transparent annular tube that can move up and down and has a sealing cap on its upper end, located on the outer side of the threaded head of a flexible tube. A scale is fixed to both the front and rear ends of the transparent annular tube. When a specific amount of liquid product needs to be extruded from inside the flexible tube, the height of the transparent annular tube is adjusted. As the tube moves, the scale fixed to it moves upwards. When the scale corresponding to the amount of liquid product is parallel to the upper end of the outlet located above the internal thread mounting groove, the flexible tube is squeezed. When the flexible tube is squeezed, the liquid product inside it enters the transparent annular tube through the threaded head and the outlet. Once the transparent annular tube is filled, the corresponding amount of liquid product has been extruded. This technical solution avoids waste caused by excessive extrusion.

[0015] 2. This utility model has an anti-detachment ring connected to the lower side of the outer surface of the transparent annular tube via a roller bearing. The anti-detachment ring, which is locked inside the annular anti-detachment groove, can prevent the transparent annular tube from falling off the hose cover. The above technical solution can prevent the transparent annular tube from falling off. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] The packaging hose body 1 (model 002), transparent annular tube 5 (model MUJIE), and guide rod 12 (model 304) mentioned in this utility model can be obtained from the market or through private customization.

[0023] Please see Figures 1 to 4 An embodiment of this utility model provides: a packaging hose with an adjustable discharge brush head, including a packaging hose body 1, a hose thread head 2 fixedly provided on the upper end face of the packaging hose body 1, a hose cover 3 provided on the outer side of the hose thread head 2, an annular groove 4 provided on the outer side of the upper end face of the hose cover 3, an external threaded ring mounting groove 8 provided on one side of the inner wall of the annular groove 4, an external threaded ring 9 fixedly provided inside the external threaded ring mounting groove 8, an internal threaded ring 10 connected to the upper side of the outer surface of the external threaded ring 9 through a threaded structure, a transparent annular tube 5 provided on the outer side of the internal threaded ring 10, a scale 6 fixedly provided on both the front and rear ends of the transparent annular tube 5, and a sealing cap 7 covering the upper end face of the transparent annular tube 5.

[0024] Above the threaded head 2 of the flexible hose is a discharge port 14 located in the middle of the inner wall of the upper end of the internal thread mounting groove 15, and the threaded head 2 of the flexible hose communicates with the interior of the transparent annular tube 5 through the discharge port 14; when it is necessary to squeeze out the corresponding amount of liquid product located inside the packaging flexible hose body 1, first manually rotate the transparent annular tube 5. When the transparent annular tube 5 rotates, the internal threaded ring 10 fixed to it will rotate along with it. Driven by the external thread of the external threaded ring 9, the rotating internal threaded ring 10 can move up and down. With the movement of the internal threaded ring 10, the transparent annular tube 5 fixed to it and the transparent annular tube 5 located on its outer surface are also affected. The scale 6 on the surface will move up and down together. At this time, adjust the height of the scale 6 until the scale of the corresponding part on the scale 6 is parallel to the upper end face of the discharge port 14 located above the internal thread mounting groove 15. Then squeeze the packaging hose body 1. When the packaging hose body 1 is squeezed, the liquid product inside it will enter the interior of the transparent annular tube 5 through the hose thread head 2 and the discharge port 14. When the interior of the transparent annular tube 5 is filled, the corresponding amount of liquid product is squeezed out. The above technical solution can avoid the situation of waste caused by excessive squeezing.

[0025] Once the inside of the transparent ring tube 5 is filled with liquid product, remove the sealing cap 7, then rotate the transparent ring tube 5 in the opposite direction. As the transparent ring tube 5 descends, the liquid product squeezed into the transparent ring tube 5 will gradually flow to the outside. The user can then apply the liquid product that has flowed to the outside to the corresponding area.

[0026] Both the transparent annular tube 5 and the scale 6 are made of transparent plastic material in one piece, and the outer surface of the transparent annular tube 5 is attached to the inner wall of the annular groove 4. By using transparent plastic material to make the transparent annular tube 5 and the scale 6, the user can observe from the outside whether the corresponding scale on the scale 6 is parallel to the upper end face of the discharge port 14, and whether the inside of the transparent annular tube 5 is filled.

[0027] A sealing filler plate 16 is fixedly provided inside the transparent annular tube 5 on the inner side of the sealing cap 7. The outer surface of the sealing filler plate 16 is in contact with the inner wall of the transparent annular tube 5. The sealing filler plate 16 is slidably connected to the inner wall of the transparent annular tube 5, and the distance between the lower end face of the sealing filler plate 16 and the discharge port 14 is the same as the overall height of the scale 6. The sealing filler plate 16 can improve the sealing performance between the sealing cap 7 and the transparent annular tube 5, thereby preventing leakage of the fluid product squeezed into the transparent annular tube 5.

[0028] An annular anti-detachment groove 11 is provided on the outer side of the bottom end of the transparent annular tube 5, located on the inner wall of the annular groove 4. An anti-detachment ring 13 is provided inside the annular anti-detachment groove 11 and is sleeved on the outer surface of the transparent annular tube 5 by a roller bearing. The outer surface of the anti-detachment ring 13 is in contact with the inner wall of the annular anti-detachment groove 11. A guide rod 12 is fixedly provided at each of the four corners inside the annular anti-detachment groove 11, and the guide rod 12 moves vertically through the anti-detachment ring 13. The anti-detachment ring 13, which is stuck inside the annular anti-detachment groove 11 and is vertically penetrated by the guide rod 12, can prevent the transparent annular tube 5 from falling off the hose cover 3. The above technical solution can prevent the transparent annular tube 5 from falling off.

[0029] The lower end face of the hose cap 3 is provided with an internal thread mounting groove 15 in the middle position. The internal thread of the internal thread mounting groove 15 matches the external thread of the hose thread head 2, and the hose cap 3 is installed on the outer surface of the hose thread head 2 through the internal thread mounting groove 15. After the liquid product inside the packaging hose body 1 is squeezed out, the hose cap 3 can be rotated to remove it directly from the outer surface of the hose thread head 2. After cleaning, it can be installed on a new packaging hose body 1 for continued use. The above technical solution enables the hose cap 3 to be reused.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
