Description

Technical Field

[0001] This application relates to the technical field of container containers, and in particular to a sealing cap for flavoring raw material containers that facilitates sampling. Background Technology

[0002] Fragrances, also known as flavorings, are substances that can be smelled or tasted. They are used as raw materials for flavoring. The production of flavorings requires a variety of preparation tools. When adding ingredients during the product formulation process, raw material containers are needed to hold the raw materials. Later, when preparing the flavoring, the raw materials in the raw material containers need to be introduced into the container for mixing.

[0003] The existing announcement number CN222555614U, entitled "Anti-Drip Flavor Raw Material Bucket," belongs to the technical field of raw material storage containers. It includes a raw material bucket with a discharge pipe fixedly connected to its bottom. A switch valve is installed in the middle of the discharge pipe, and a connecting pipe is fixedly connected to its end. A rotating groove is provided on the outside of the connecting pipe, and a discharge pipe is rotatably connected inside the connecting pipe. A fixing block is fixedly connected to the outside of the discharge pipe and rotatably connected inside the rotating groove. A rotating shaft is fixedly connected to the outside of the end of the discharge pipe, and a cap is rotatably connected inside the rotating shaft. The discharge pipe has an L-shaped structure. When discharging flavor raw materials, the discharge pipe is rotated so that the end opening is vertically downward, thus discharging the flavor raw materials. After discharging, the discharge pipe is rotated so that the end opening is vertically upward, and then the cap is rotated to close the discharge port, preventing dripping and avoiding the release of harmful gases from residual flavorings.

[0004] Regarding the aforementioned technologies, the inventors discovered that the raw material barrel discharge pipe and connecting pipe are assembled using a rotating connection method. However, the discharge pipe and connecting pipe lack limiting and locking components after rotation. Later, there is residual flavoring material in the discharge pipe, which increases the overall weight of the discharge pipe. Later, under the influence of gravity, the discharge pipe rotates on the connecting pipe, causing the discharge pipe port to face downwards, resulting in the residual material in the discharge pipe flowing downwards. Utility Model Content

[0005] To overcome the lack of limiting and locking components between the existing rotating discharge pipe and connecting pipe, which leads to residual flavoring material in the discharge pipe and increases the overall weight of the discharge pipe, and the discharge pipe rotating on the connecting pipe due to gravity, causing the discharge pipe port to face downwards and resulting in the residual material flowing down the discharge pipe, this application provides a sealing cap for flavoring raw material barrels that facilitates sampling.

[0006] The sealing cap for flavoring raw material containers that facilitates sampling provided in this application adopts the following technical solution:

[0007] A sealing cap for a flavoring raw material barrel that facilitates sampling includes a raw material barrel and a barrel lid. One end of the raw material barrel is open, and the barrel lid is assembled at the opening. A connecting pipe is horizontally connected and fixed to the bottom of the front face of the barrel lid, and the other end of the connecting pipe is connected and assembled with a valve. The other end of the valve is connected and provided with a discharge pipe. The discharge pipe includes a connecting pipe, an L-shaped pipe, and a sleeve. One end of the connecting pipe is connected and assembled to the other end of the valve, and the other end of the connecting pipe is horizontally connected and fixed with the sleeve. One end of the L-shaped pipe is horizontally connected and fixed with a limiting cylinder, and the limiting cylinder is rotatably sleeved on the sleeve. Multiple slots are evenly opened on the inner wall of the limiting cylinder near the opening end. A locking strip is horizontally fixed on the top of the outer wall of the sleeve away from the opening end, and the locking strip is limited and engaged with the slots on the limiting cylinder.

[0008] By adopting the above technical solution, the flavoring raw materials are added to the raw material tank during use, and then the tank lid is threaded and sealed to the opening of the raw material tank. When it is necessary to discharge the flavoring raw materials from the raw material tank later, the connecting pipe and the discharge pipe are connected and assembled through a valve. To discharge the flavoring raw materials from the raw material tank, first, pull the limiting cylinder at the liquid inlet end of the L-shaped tube and slide it on the sleeve of the connecting pipe, causing the groove on the inner wall of the limiting cylinder to slide out of the retaining strip on the outer wall of the sleeve. Then, rotate the L-shaped tube to set the discharge port downwards, and then loosen the limiting cylinder at the liquid inlet end of the L-shaped tube from the sleeve of the connecting pipe. Slide the valve to engage the groove on the inner wall of the limiting cylinder with the locking strip on the outer wall of the sleeve. Then, rotate the valve to allow the flavoring raw material to be guided from the raw material barrel into the L-shaped tube through the connecting pipe and discharged. After discharge, to prevent excess raw material from dripping down the L-shaped tube, repeat the above operation. Rotate the L-shaped tube to set the discharge port upward, and then loosen the limiting cylinder at the liquid inlet end of the L-shaped tube and slide it on the sleeve of the connecting pipe to engage the groove on the inner wall of the limiting cylinder with the locking strip on the outer wall of the sleeve. This prevents the L-shaped tube from deflecting later, causing the discharge port to face downward and resulting in raw material dripping.

[0009] Optionally, a first spring is horizontally sleeved on the outside of the sleeve, with one end of the first spring rotatably connected to the end of the sleeve and the other end of the first spring fixed to the end of the limiting cylinder.

[0010] By adopting the above technical solution, the presence of the first spring creates deformation pressure between the L-shaped tube and the connecting tube, which facilitates the subsequent secure assembly and docking of the limiting cylinder at the liquid inlet end of the L-shaped tube on the sleeve of the connecting tube.

[0011] Optionally, a rotating plate is horizontally fixed on the outer wall of the vertical part of the L-shaped tube, and a tube is vertically rotatably connected to the top surface of the rotating plate.

[0012] By adopting the above technical solution, the insert connected to the rotating plate fixed on the outer wall of the L-shaped tube is convenient for later rotation and offset of the sealing component used to seal the opening of the L-shaped tube.

[0013] Optionally, a pull bracket is vertically slidably inserted into the insert, and a second spring is vertically fixed at the bottom of the pull bracket, with the bottom end of the second spring fixed to the top surface of the insert.

[0014] By adopting the above technical solution, in order to ensure the sealing tightness of the sealing component at the opening of the L-shaped tube during use, the deformation force of the second spring is used to push the pull bracket to drive the sealing component to seal the opening of the L-shaped tube.

[0015] Optionally, a pressure cap is vertically fixed to the top of the bracket, and a sealing gasket is fixed to the outside of the pressure cap.

[0016] By adopting the above technical solution, the pressure cap at the top of the bracket drives the sealing gasket to be inserted into the opening of the L-shaped tube, and the sealing gasket improves the sealing firmness of the opening of the L-shaped tube.

[0017] Optionally, a sealing cylinder is fixedly connected to the vertical opening of the L-shaped tube, and a pressure cap is inserted into the sealing cylinder.

[0018] By adopting the above technical solution, the sealing gap between the sealing cylinder of the L-shaped tube and the sealing gasket of the outer wall of the pressure cover is sealed, ensuring the sealing firmness of the discharge end of the L-shaped tube and preventing the fragrance in the L-shaped tube from escaping.

[0019] Optionally, both the connecting pipe and the end of the connecting pipe near the valve are connected to and fixed with a threaded tube, and the threaded tube is threadedly assembled and connected to the valve.

[0020] By adopting the above technical solution, the connecting pipe and the threaded pipe that are fixed to the connecting pipe are assembled and connected to the valve threadedly, which facilitates the assembly and connection of the valve with the connecting pipe and the connecting pipe and the connecting pipe, and ensures a firm connection.

[0021] Optionally, the inner wall of the opening of the raw material barrel is provided with internal threads, and the outer side of the barrel cover is provided with external threads, and the barrel cover is threadedly connected to the opening of the raw material barrel.

[0022] By adopting the above technical solution, the opening of the raw material barrel is threadedly assembled with the barrel lid, which facilitates later disassembly and assembly, and the addition of supplementary flavoring raw materials.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] During use, the flavoring raw materials are added to the raw material tank, and then the tank lid is threaded and sealed to the opening of the raw material tank. When it is necessary to discharge the flavoring raw materials from the raw material tank later, the connecting pipe and the discharge pipe are connected and assembled via a valve. To discharge the flavoring raw materials from the raw material tank, first pull the limiting cylinder at the inlet end of the L-shaped tube and slide it on the sleeve of the connecting pipe, causing the groove on the inner wall of the limiting cylinder to slide out of the retaining strip on the outer wall of the sleeve. Then, rotate the L-shaped tube to set the discharge port downwards. Finally, release the limiting cylinder at the inlet end of the L-shaped tube and slide it on the sleeve of the connecting pipe to allow the limiting cylinder to slide out. The groove on the inner wall of the cylinder is engaged with the retaining strip on the outer wall of the sleeve. Then, the valve is turned to allow the flavoring raw material to be guided from the raw material barrel through the connecting pipe into the L-shaped pipe for discharge. After discharge, in order to prevent excess raw material in the L-shaped pipe from dripping downwards, the above operation is repeated. The L-shaped pipe is rotated to set the discharge port upwards, and then the retaining cylinder at the liquid inlet end of the L-shaped pipe is released and slid on the sleeve of the connecting pipe. This allows the groove on the inner wall of the retaining cylinder to engage with the retaining strip on the outer wall of the sleeve, preventing the L-shaped pipe from deflecting later and causing the discharge port to face downwards, resulting in raw material dripping.

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] This application discloses a sealing cap for flavoring raw material containers that facilitates sampling. (See also...) Figure 1 , Figure 2 , Figure 3 and Figure 4A sealing cap for a flavoring raw material barrel that facilitates sampling includes a raw material barrel 1 and a barrel cover 2. One end of the raw material barrel 1 is open, and the barrel cover 2 is assembled at the opening of the raw material barrel 1. A connecting pipe 3 is horizontally connected and fixed to the bottom of the front end face of the barrel cover 2, and the other end of the connecting pipe 3 is connected and assembled with a valve 5. The other end of the valve 5 is connected and provided with a discharge pipe 4. The discharge pipe 4 includes a connecting pipe 41, an L-shaped pipe 42 and a sleeve 43. One end of the connecting pipe 41 is connected and assembled to the other end of the valve 5, and the other end of the connecting pipe 41 is horizontally connected and fixed with the sleeve 43. One end of the L-shaped pipe 42 is horizontally connected and fixed with a limiting cylinder 46, and the limiting cylinder 46 is rotatably sleeved on the sleeve 43. Multiple slots 47 are evenly opened on the inner wall of the limiting cylinder 46 near the opening end. A locking strip 44 is horizontally fixed on the top of the outer wall of the sleeve 43 away from the opening end, and the locking strip 44 is limited and locked with the slots 47 on the limiting cylinder 46.

[0033] By adopting the above technical solution, the flavoring raw material is added to the raw material tank 1 during use, and then the tank lid 2 is threaded and sealed to the opening of the raw material tank 1. When it is necessary to discharge the flavoring raw material from the raw material tank 1 later, the connecting pipe 3 and the discharge pipe 4 are connected and assembled through the valve 5. To discharge the flavoring raw material from the raw material tank 1, firstly, the limiting cylinder 46 at the liquid inlet end of the L-shaped pipe 42 is pulled and slid on the sleeve 43 of the connecting pipe 41, so that the groove 47 on the inner wall of the limiting cylinder 46 slides out from the retaining strip 44 on the outer wall of the sleeve 43. Then, the L-shaped pipe 42 is rotated so that the discharge port is set downward. Then, the limiting cylinder 46 at the liquid inlet end of the L-shaped pipe 42 is released from sliding on the sleeve 43 of the connecting pipe 41. The movement causes the groove 47 on the inner wall of the limiting cylinder 46 to engage with the retaining strip 44 on the outer wall of the sleeve 43. Then, the valve 5 is turned to allow the flavoring raw material to be guided from the raw material barrel 1 through the connecting pipe 3 into the L-shaped pipe 42 for discharge. After discharge, in order to prevent excess raw material in the L-shaped pipe 42 from dripping downwards, the above operation is repeated. The L-shaped pipe 42 is rotated to set the discharge port upwards. Then, the limiting cylinder 46 at the liquid inlet end of the L-shaped pipe 42 is released and slides on the sleeve 43 of the connecting pipe 41, so that the groove 47 on the inner wall of the limiting cylinder 46 engages with the retaining strip 44 on the outer wall of the sleeve 43 for limiting. This prevents the L-shaped pipe 42 from deflecting later, causing the discharge port to drop downwards and resulting in raw material dripping.

[0034] Reference Figure 4 A first spring 45 is horizontally sleeved on the outside of the sleeve 43, with one end of the first spring 45 rotatably connected to the end of the sleeve 43 and the other end of the first spring 45 fixed to the end of the limiting cylinder 46. The presence of the first spring 45 creates deformation pressure between the L-shaped tube 42 and the connecting tube 41, which facilitates the later secure assembly and docking of the limiting cylinder 46 at the liquid inlet end of the L-shaped tube 42 with the sleeve 43 of the connecting tube 41.

[0035] Reference Figure 4 and Figure 5A rotating plate 421 is horizontally fixed to the outer wall of the vertical part of the L-shaped tube 42, and a tube 422 is vertically and rotatably connected to the top surface of the rotating plate 421. The tube 422 rotatably connected to the rotating plate 421 fixed to the outer wall of the L-shaped tube 42 facilitates later rotation and offset for sealing the sealing component at the opening of the L-shaped tube 42. A pull bracket 423 is vertically slidably inserted into the tube 422, and a second spring 424 is vertically fixed to the bottom of the pull bracket 423, with the bottom end of the second spring 424 fixed to the top surface of the tube 422. In use, to ensure the sealing tightness of the sealing component at the opening of the L-shaped tube 42, the deformation force of the second spring 424 pushes the pull bracket 423 to drive the sealing component to seal the opening of the L-shaped tube 42.

[0036] Reference Figure 4 and Figure 5 A pressure cover 425 is vertically fixed to the top of the pull bracket 423, and a sealing gasket 426 is fixed to the outside of the pressure cover 425. The pressure cover 425 at the top of the pull bracket 423 drives the sealing gasket 426 to be inserted into the opening of the L-shaped tube 42, and the sealing gasket 426 improves the sealing firmness of the opening of the L-shaped tube 42. A sealing cylinder 427 is fixedly connected to the vertical opening of the L-shaped tube 42, and the pressure cover 425 is inserted into the sealing cylinder 427. The sealing cylinder 427 of the L-shaped tube 42 and the sealing gasket 426 on the outer wall of the pressure cover 425 seal the gap, ensuring the sealing firmness of the discharge end of the L-shaped tube 42 and preventing the fragrance in the L-shaped tube 42 from escaping.

[0037] Reference Figure 3 and Figure 4 Both the connecting pipe 3 and the connecting pipe 41 have a threaded pipe 6 fixedly connected to one end near the valve 5, and the threaded pipe 6 is threadedly assembled with the valve 5. The threaded connection between the connecting pipe 3 and the connecting pipe 41 and the valve 5 facilitates the assembly and connection of the valve 5 with the connecting pipe 3 and the connecting pipe 41, ensuring a secure connection.

[0038] Reference Figure 2 and Figure 3 The inner wall of the opening of the raw material barrel 1 has an internal thread, and the outer side of the barrel cover 2 has an external thread. The barrel cover 2 is threadedly connected to the opening of the raw material barrel 1. The threaded connection between the opening of the raw material barrel 1 and the barrel cover 2 facilitates later disassembly and assembly for adding and replenishing flavoring raw materials.

[0039] The implementation principle of the sealing cap for a flavoring raw material barrel that facilitates sampling in this application embodiment is as follows: During use, flavoring raw materials are added to the raw material barrel 1, and then the barrel cap 2 is threaded and sealed to the opening of the raw material barrel 1. When flavoring raw materials need to be discharged from the raw material barrel 1 later, the connecting pipe 3 and the discharge pipe 4 are connected and assembled through the valve 5. To discharge flavoring raw materials from the raw material barrel 1, firstly, the limiting cylinder 46 at the liquid inlet end of the L-shaped pipe 42 is pulled and slid on the sleeve 43 of the connecting pipe 41, causing the groove 47 on the inner wall of the limiting cylinder 46 to slide out of the retaining strip 44 on the outer wall of the sleeve 43. Then, the L-shaped pipe 42 is rotated so that the discharge port is facing downwards. Then, the limiting cylinder 46 at the liquid inlet end of the L-shaped pipe 42 is released and slid on the sleeve 43 of the connecting pipe 41, causing the groove 47 on the inner wall of the limiting cylinder 46 to engage with the retaining strip 44 on the outer wall of the sleeve 43. Finally, the valve 5 is rotated, allowing the flavoring raw materials to be guided from the raw material barrel 1 into the L-shaped pipe through the connecting pipe 3. After discharge, to prevent excess material from dripping downwards from L-shaped tube 42, repeat the above operation. Rotate L-shaped tube 42 to set the discharge port upwards, then loosen the limiting cylinder 46 at the liquid inlet end of L-shaped tube 42 and slide it on the sleeve 43 of connecting pipe 41, so that the groove 47 on the inner wall of the limiting cylinder 46 is engaged with the locking strip 44 on the outer wall of the sleeve 43. At the same time, during discharge, pull the puller 423 to slide vertically upwards in the insert 422. The second spring 424 deforms, and then the insert 422 rotates on the rotating plate 421, causing the pressure cover 425 to shift off the discharge port of the L-shaped tube 42. When the material is discharged, the insert 422 rotates on the rotating plate 421, so that the pressure cover 425 is positioned above the discharge port of the L-shaped tube 42. The pull bracket 423 is released, and under the action of the deformation force of the second spring 424, the pressure cover 425 is pushed to drive the sealing gasket 426 to seal the discharge port of the L-shaped tube 42.

[0040] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
