Abstract
Description
Technical Field
[0001] This utility model relates to the field of chewing gel materials technology, and in particular to a chewing gel material dispensing device with an adjustable opening size. Background Technology
[0002] Chewing gel materials, as a special form of product, are widely used in many fields due to their soft texture and ease of chewing and swallowing. In oral care, they can be used to clean teeth and relieve oral discomfort; in nutritional supplementation, they can provide balanced nutrition for special populations such as children and the elderly; and in medical rehabilitation, they can assist patients with swallowing dysfunction in supplementing nutrition and medication.
[0003] However, current chewable gel dispensing devices on the market have many drawbacks. Most existing devices are simple tubular packages with a fixed dispensing opening size. When dealing with children or others who need to dispense small amounts, the fixed, large opening easily leads to excessive gel being dispensed, resulting in material waste and potential soiling of the user or the surrounding environment. Conversely, for adults who need to dispense larger amounts, the small opening increases the difficulty of dispensing, often requiring multiple squeezes, making the operation cumbersome, and easily contaminating the gel material during the squeezing process.
[0004] Furthermore, the existing dispensing device has significant shortcomings in its push-pull structure design. The piston of the push-pull assembly is often fixedly connected to the push rod and cannot be disassembled. After use, the gel material remaining on the piston surface is difficult to clean thoroughly, easily leading to bacterial growth and affecting the hygiene and safety of subsequent uses. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable opening size device for dispensing chewing gel materials.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: it includes a storage cylinder, both ends of which are provided with openings. A pushing component is connected to one of the openings, and a connecting cover is threaded to the other opening. A discharge pipe is connected to the side of the connecting cover away from the storage cylinder. A sleeve plate is welded to the surface of the connecting cover, and an opening adjustment component for adjusting the size of the discharge pipe outlet is connected to the sleeve plate.
[0007] As a further description of the above technical solution:
[0008] The pushing assembly includes a push rod and a piston slidably disposed in a storage cylinder. A threaded cylinder is fixedly connected to one side of the piston, and a threaded column is fixedly connected to one end of the push rod. The threaded column is threadedly connected to the threaded cylinder. One end of the push rod extends to the outside of the storage cylinder and is fixedly connected to a limit block. Slide plates are fixedly connected to both sides of the push rod. Slide grooves are formed on the inner surfaces of both sides of the storage cylinder. The two slide plates are slidably connected in the two slide grooves respectively.
[0009] As a further description of the above technical solution:
[0010] The piston has a sealing ring on its outer side wall with a circular cross-section, and the sealing ring fits tightly against the inner side wall of the storage cylinder.
[0011] As a further description of the above technical solution:
[0012] The piston is made of food-grade polypropylene plastic, and the sealing ring is made of food-grade rubber.
[0013] As a further description of the above technical solution:
[0014] The opening adjustment assembly includes four fixed blocks fixed at the four corners of one side of the sleeve plate. A lead screw is rotatably connected between two fixed blocks on one side. One end of the lead screw passes through a fixed block and is fixed to a rotating block. A slide rod is fixed between two fixed blocks on the other side. An L-shaped threaded sleeve is threaded to the outside of the lead screw. An L-shaped sliding sleeve is slidably connected to the outside of the slide rod. A sealing cap is fixed between the L-shaped threaded sleeve and the L-shaped sliding sleeve.
[0015] As a further description of the above technical solution:
[0016] A rubber gasket is bonded to the side of the sealing cover near the sleeve plate, and the rubber gasket is in close contact with the discharge pipe.
[0017] As a further description of the above technical solution:
[0018] The storage cylinder is transparent, and scale lines are provided on the outer wall of the storage cylinder along the axial direction.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Reference Figures 1-5An embodiment of this utility model includes a storage cylinder 1, with openings at both ends. A pushing component is connected to one opening, and a connecting cover 7 is threaded to the other opening. A discharge pipe 17 is connected to the side of the connecting cover 7 away from the storage cylinder 1. A sleeve plate 8 is welded to the surface of the connecting cover 7, and an opening adjustment component for adjusting the size of the outlet of the discharge pipe 17 is connected to the sleeve plate 8.
[0031] The pushing assembly includes a push rod 4 and a piston 6 slidably disposed in a storage cylinder 1. A threaded cylinder 9 is fixedly connected to one side of the piston 6, and a threaded post 10 is fixedly connected to one end of the push rod 4. The threaded post 10 is threadedly connected to the threaded cylinder 9. One end of the push rod 4 extends to the outside of the storage cylinder 1 and is fixedly connected to a limiting block 3. The limiting block 3 provides a gripping point for the user to push the push rod 4, and its size is larger than the opening of the storage cylinder 1 to prevent the push rod 4 from sliding completely into the storage cylinder 1, thus serving as a limiting function. Slide plates 5 are fixedly connected to both sides of the push rod 4, and grooves 2 are opened on the inner surfaces of both sides of the storage cylinder 1. The two slide plates 5 are slidably connected in the two grooves 2 respectively to ensure the stability and straightness of the push rod 4's movement. A sealing ring with a circular cross-section is provided on the outer wall of the piston 6. The sealing ring fits tightly against the inner wall of the storage cylinder 1, enhancing the sealing of the storage cylinder 1 and preventing the gel material from flowing out of the piston. The piston 6 is made of food-grade polypropylene plastic, and the sealing ring is made of food-grade rubber. The opening adjustment component includes four fixed blocks fixed at the four corners of one side of the sleeve plate 8. A screw rod 13 is rotatably connected between two fixed blocks on one side. One end of the screw rod 13 passes through a fixed block and is fixed to a rotating block 14. A slide rod 12 is fixed between two fixed blocks on the other side. An L-shaped threaded sleeve 16 is threaded to the outside of the screw rod 13. An L-shaped sliding sleeve 15 is slidably connected to the outside of the slide rod 12. A sealing cover 11 is fixed between the L-shaped threaded sleeve 16 and the L-shaped sliding sleeve 15. The L-shaped sliding sleeve 15 ensures the smooth movement of the sealing cover 11 under the guidance of the slide rod 12. A rubber pad is bonded to the side of the sealing cover 11 near the sleeve plate 8. The rubber pad is in close contact with the discharge pipe 17. The storage cylinder 1 is transparent. Scale lines are set on the outer wall of the storage cylinder 1 along the axial direction.
[0032] Working Principle: Before dispensing the chewable gel material, the size of the dispensing nozzle must be adjusted according to the usage requirements. The opening adjustment component plays a crucial role. Rotating the rotating block 14 causes the lead screw 13 to rotate between two fixed blocks. Since the L-shaped threaded sleeve 16 is threadedly connected to the lead screw 13, and the L-shaped sliding sleeve 15 slides on the slide rod 12, limiting the L-shaped threaded sleeve 16, the rotation of the lead screw 13 drives the L-shaped threaded sleeve 16 to move axially along the lead screw 13, thereby causing the L-shaped sliding sleeve 15 to slide synchronously on the slide rod 12, making the sealing cap 11 move closer to or away from the dispensing tube 17. As the sealing cap 11 gradually moves away from the dispensing tube 17, the outlet of the dispensing tube 17 gradually opens. By controlling the position of the sealing cap 11, the opening size of the outlet can be precisely adjusted to meet the needs of different dosages.
[0033] After adjusting the discharge port, the gel material can be pushed and collected. The pushing component starts working. Hold the limit block 3 and push the push rod 4. The slide plates 5 on both sides of the push rod 4 slide in the grooves 2 on the inner wall of the storage cylinder 1, providing guidance for the movement of the push rod 4. The push rod 4 is threadedly connected to the threaded cylinder 9 of the piston 6 through the threaded post 10, which will drive the piston 6 to slide forward inside the storage cylinder 1. The food-grade rubber sealing ring on the outer wall of the piston 6 fits tightly against the inner wall of the storage cylinder 1, ensuring the sealing of the inside of the storage cylinder 1 and preventing the gel material from leaking from the gap between the piston 6 and the storage cylinder 1. As the piston 6 advances, the chewable gel material in the storage cylinder 1 is squeezed and squeezed out through the discharge pipe 17 of the connecting cover 7. At this time, the amount of gel squeezed out can be precisely controlled by observing the scale lines on the outer wall of the storage cylinder 1 and combining the distance the piston 6 moves.
[0034] After use, rotate the rotating block 14 in the opposite direction so that the sealing cover 11 comes close to and fits against the discharge pipe 17. The rubber pad on one side of the sealing cover 11 is in close contact with the discharge pipe 17 to seal the discharge port, effectively preventing external dust, bacteria and other contaminants from entering the storage cylinder 1 and contaminating the gel material, while also preventing the gel material from drying out and deteriorating due to exposure to air.
[0035] When it is necessary to clean the device or replace the gel material, pull the limit block 3 to move the push rod 4 and piston 6 out of the storage cylinder 1. Since the push rod 4 and piston 6 are detachably connected by the threaded column 10 and the threaded cylinder 9, the push rod 4 can be rotated to separate it from the piston 6, which facilitates thorough cleaning and disinfection of the piston 6 and the sealing ring. At the same time, the connecting cover 7 is threadedly connected to the storage cylinder 1. By unscrewing the connecting cover 7, the inside of the storage cylinder 1 can be cleaned or refilled with gel material. The operation is convenient and ensures the hygiene and safety of the device.
