Abstract
Description
Technical Field
[0001] This utility model belongs to the field of kudzu polysaccharide storage technology, and specifically relates to a sealed container for storing kudzu polysaccharides that is protected against oxidation and moisture. Background Technology
[0002] The sealed containers used for storing kudzu polysaccharides are often barrel-shaped containers made of thickened cardboard, also known as cardboard drums. The drums are usually lined with double-layer film or aluminum foil bags, and the lids of the cardboard drums have steel hoops. One end of the steel hoop has a rotating shaft, and a clamping handle is fixed on the circumference of the shaft. By tightening the steel hoop with the clamping handle, the cardboard drum and the lid are fixed under pressure, thereby achieving an anti-oxidation and moisture-proof seal.
[0003] In existing technology, the steel hoop of cardboard drum lid is usually an open ring structure with the two ends not connected. When tightened by pressing the handle, the contraction of the steel hoop does not cause the two ends of the steel hoop to connect, and there is always a gap at the opening at both ends, making it difficult to form a continuous and complete sealing ring between the lid and the drum body.
[0004] Moisture and oxygen from the outside air can easily seep into the container through the tiny gap caused by this opening, causing the kudzu polysaccharide to absorb moisture, clump, and oxidize, seriously affecting the product quality and shelf life.
[0005] Furthermore, the locking mechanism of existing clamping handles typically relies on friction for its locking state. Under conditions of transportation, handling, or environmental vibration, it is prone to loosening or even accidental disengagement, leading to a sudden drop in sealing pressure and causing seal failure. Operators also cannot visually and reliably determine whether the container is in a fully locked and sealed state. Utility Model Content
[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a sealed container for storing kudzu polysaccharides to prevent oxidation and moisture.
[0007] To achieve the above objectives, this utility model adopts the following technical solution: a sealed container for storing kudzu polysaccharides, comprising a barrel body and a barrel lid. A steel hoop is provided on the surface of the barrel lid. One end of the steel hoop is rotatably connected to an end shaft. A clamping handle is provided on the circumference of the end shaft. A sealing module is provided at the end of the steel hoop near the end shaft. A fixing module is provided on the inner wall of the clamping handle. The sealing module includes: a driven gear fixed to the circumference of the end shaft; an arc-shaped groove formed on the circumference of one end of the steel hoop; a T-shaped limiting member whose surface is slidably connected to the inner wall of the arc-shaped groove; a U-shaped toothed member whose two ends are fixed to the circumference of the T-shaped limiting member, and whose inner circumference has a toothed groove; and a U-shaped arc member whose outer circumference is fixed to the inner circumference of the T-shaped limiting member.
[0008] Preferably, the end of the U-shaped arc member near the other end of the steel hoop is set as a tapered end, the thickness of the tapered end gradually decreases towards the other end of the steel hoop, and the edge of the tapered end near the other end of the steel hoop is set as a rounded edge.
[0009] Preferably, both ends of the U-shaped arc member are set as arched ends, one end of the arched end is fixed to the outer peripheral surface of the T-shaped limiting member, and the side of the arched end near the clamping handle is set as a parallel end.
[0010] Preferably, a shielding arc plate is fixed to the arched end surface away from the clamping handle, and the inner circumferential surface of the shielding arc plate is tightly fitted to the arc groove on the outer circumferential surface of the steel hoop.
[0011] Preferably, the fixing module includes: a rotating column disposed on the inner wall of the pressing handle; a return spring, one end of which is fixed to one end of the rotating column; an elliptical component, one side of which is fixed to the other end of the rotating column; a fixing post, one end of which is fixed to one end of the elliptical component; and a fixing groove, one side of the pressing handle having a fixing groove whose diameter matches the diameter of the fixing post.
[0012] Preferably, a control handle is fixed to the other side of the elliptical component; and multiple limiting points are fixed to one side of the clamping handle.
[0013] Preferably, a large-diameter plate is fixed to one end of the rotating column near the return spring, and one end of the large-diameter plate is fixed to one end of the return spring; a limiting groove is provided at the rotating column on the inner wall of the clamping handle.
[0014] Preferably, the inner wall of the clamping handle is provided with an arc groove near the rotating column, and the edge of the arc groove away from the limiting circular groove is set as a guiding arc surface; the inner wall of the arc groove is nested with a positioning arc piece, and both ends of the positioning arc piece are fixed to the circumference of the rotating column.
[0015] In summary, this utility model has the following beneficial effects: 1. This utility model provides a sealing module at the open end of a steel hoop. This module includes a T-shaped restrictor that can slide along an arc groove and a U-shaped arc member fixed thereto. When the clamping handle drives the module to move through the meshing of the driven gear with the tooth groove on the U-shaped arc member, the U-shaped arc member can fill and seal the gap between the two ends of the steel hoop, forming a continuous sealing ring that effectively prevents water vapor and oxygen from entering from here. 2. This utility model incorporates a fixing module within the clamping handle. This module includes a fixed insertion post driven by a rotating column and a corresponding insertion slot. When the clamping handle is in the locked position, the operator can pull down the control handle and rotate the elliptical component around the rotating column, causing the insertion post to align with the insertion slot under the constraint of the limiting point. Under the action of the return spring, the insertion post engages with the insertion slot, forming a mechanical interlock and effectively preventing loosening due to vibration. 3. This utility model sets the end of the U-shaped arc piece to a gradually thinning end and a rounded edge, which facilitates its smooth insertion and docking and prevents the U-shaped arc piece from damaging the barrel body; the shielding arc plate further covers the gaps in the arc groove, further preventing the T-shaped restrictor from sliding to the limit of one end of the steel hoop, which would cause part of the arc groove to lose its shielding and reduce the moisture-proof and dust-proof effect.

[0018] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.
[0019] The specific embodiments of this utility model are described below with reference to the accompanying drawings: Example
[0020] refer to Figures 1-11 A sealed container for storing kudzu polysaccharides, resistant to oxidation and moisture, includes a barrel body 1 and a barrel lid 101. A steel hoop 102 is provided on the surface of the barrel lid 101. One end of the steel hoop 102 is rotatably connected to an end shaft 104. A clamping handle 103 is provided on the circumference of the end shaft 104. A sealing module 2 is provided at the end of the steel hoop 102 near the end shaft 104. A fixing module 5 is provided on the inner wall of the clamping handle 103. The sealing module 2 includes a driven gear 201, which is fixed to the end shaft 104. The shaft 104 has a circumferential surface; an arc-shaped groove 206 is formed on the circumferential surface of one end of the steel hoop 102; a T-shaped restrictor 203 is slidably connected to the inner wall of the arc-shaped groove 206; a U-shaped toothed member 204 is fixed at both ends to the circumferential surface of the T-shaped restrictor 203, and a toothed groove 205 is formed on the inner circumferential surface of the U-shaped toothed member 204; and a U-shaped arc member 202 is fixed to the inner circumferential surface of the T-shaped restrictor 203.
[0021] Specifically, by setting up a sealing module 2, this module includes a driven gear 201 fixed on the end shaft 104, an arc groove 206 formed on the steel hoop 102, a T-shaped restrictor 203 slidably connected to the arc groove 206, a U-shaped toothed member 204 fixed to the T-shaped restrictor 203 and having a toothed groove 205 formed on its inner circumferential surface, and a U-shaped arc member 202 fixed to the T-shaped restrictor 203. When the clamping handle 103 is rotated, the meshing of the driven gear 201 and the U-shaped toothed member 204 drives the entire sealing module 2 to move along the arc groove 206, causing the U-shaped arc member 202 to fill the gap at both ends of the steel hoop 102, achieving dynamic sealing at the opening of the steel hoop 102, effectively filling the inherent gaps in the traditional structure, and significantly improving the overall moisture-proof and oxidation-proof performance of the container.
[0022] The end of the U-shaped arc member 202 near the other end of the steel hoop 102 is set as a tapered end 3. The thickness of the tapered end 3 gradually decreases towards the other end of the steel hoop 102, and the edge of the tapered end 3 near the other end of the steel hoop 102 is set as a rounded edge.
[0023] Specifically, by setting one end of the U-shaped arc 202 near the other end of the steel hoop 102 as a gradually thinning end 3 with a gradually decreasing thickness, and setting its edge as a rounded edge, good guidance is provided and sharp edges are eliminated, ensuring that the sealing components can smoothly and without damage complete the butt seal, and avoiding scratches or damage to the container or other components during the sealing process.
[0024] Both ends of the U-shaped arc member 202 are set as arched ends 4. One end of the arched end 4 is fixed to the outer peripheral surface of the T-shaped restrictor 203, and the side of the arched end 4 near the clamping handle 103 is set as a parallel end 401.
[0025] A shielding arc plate 6 is fixed on the surface of the arched end 4 away from the clamping handle 103. The inner circumferential surface of the shielding arc plate 6 is tightly fitted with the arc groove 206 on the outer circumferential surface of the steel hoop 102.
[0026] Specifically, by setting both ends of the U-shaped arc member 202 as arched ends 4 to increase structural rigidity, and fixing a shielding arc plate 6 to one of the arched ends 4 so that it fits tightly against the outer circumference of the steel hoop 102 at the arc groove 206, the gap that may be exposed by the sliding trajectory of the T-shaped restrictor 203 is shielded, thereby enhancing the structural strength and stability of the sealing module 2 and further improving the protection level of the sealing area to prevent dust and moisture from entering from the gaps of the moving parts. The other arched end 4 is set as a parallel end 401 to prevent it from colliding with the clamping handle 103.
[0027] The fixing module 5 includes: a rotating post 501, which is disposed on the inner wall of the clamping handle 103; a return spring 502, one end of which is fixed to one end of the rotating post 501; an elliptical part 503, one side of which is fixed to the other end of the rotating post 501; a fixing post 504, one end of which is fixed to one end of the elliptical part 503; and a fixing groove 505, which is provided on one side of the clamping handle 103, and the diameter of the fixing groove 505 matches the diameter of the fixing post 504.
[0028] A control handle 7 is fixed to the other side of the elliptical part 503; multiple limiting points 802 are fixed to one side of the clamping handle 103.
[0029] A large-diameter plate 8 is fixed to one end of the rotating column 501 near the return spring 502, and one end of the large-diameter plate 8 is fixed to one end of the return spring 502; a limiting groove 801 is provided at the rotating column 501 on the inner wall of the clamping handle 103.
[0030] Specifically, after the staff fixes the barrel body 1 and the barrel lid 101, they can pull down the elliptical part 503 by controlling the handle 7, causing the elliptical part 503 to leave the inner wall of the clamping handle 103. At the same time, the return spring 502 stretches and accumulates elastic potential energy, and the large-diameter plate 8 limits the length of the rotating column 501 away from the clamping handle 103. Then, the staff rotates the elliptical part 503 around the rotating column 501 as the axis, so that the insertion post 504 is aligned with the insertion groove 505. Then, the staff releases the handle, causing the return spring 502 to release elastic potential energy and pull the rotating column 501 and the elliptical part 503 back, so that the insertion post 504 is inserted into the insertion groove 505, thereby preventing the clamping handle 103 from being opened by transportation or accidental operation, and improving the moisture-proof and dust-proof sealing effect.
[0031] An arc groove 901 is provided on the inner wall of the clamping handle 103 near the rotating column 501. The edge of the arc groove 901 away from the limiting circular groove 801 is set as a guiding arc surface 902. A positioning arc piece 9 is nested in the inner wall of the arc groove 901. Both ends of the positioning arc piece 9 are fixed to the circumference of the rotating column 501.
[0032] Specifically, when the elliptical part 503 is inside the clamping handle 103, the positioning arc plate 9 is nested in the inner wall of the arc groove 901 to temporarily fix the elliptical part 503, thereby preventing the elliptical part 503 from detaching from the inner wall of the clamping handle 103 when subjected to vibration. The guiding arc surface 902 facilitates the positioning arc plate 9 to detach from the arc groove 901, thereby facilitating operation by the staff. Example
[0033] refer to Figures 1-11 Staff members used the structure disclosed in this utility model in the GMP cleanroom of a kudzu deep processing enterprise. A batch of freshly extracted kudzu polysaccharides is undergoing packaging. Operators are using the anti-oxidation and moisture-proof sealed container of this invention for sealing. The container is made of a five-layer composite cardboard body, with a 0.1 mm thick aluminum foil bag lined the inner wall. The steel hoops around the lid are made of 1.2 mm thick 304 stainless steel strips, 25 mm wide, and connected to the clamping handle via an end shaft.
[0034] When the operator heat-seals the aluminum foil bag filled with kudzu polysaccharide and places it into the barrel, closes the lid, and presses down the handle, the driven gear of the sealing module 2, fixed to the end shaft, begins to rotate, forming a transmission with the toothed groove on the inner circumference of the U-shaped toothed component. The U-shaped toothed component drives the T-shaped limiting component to slide smoothly along the arc groove at the end of the steel hoop, pushing the U-shaped arc component towards the opening of the steel hoop. The U-shaped arc component is made of food-grade silicone, and its 3mm thick tapered end and rounded edge design allow it to smoothly insert into the gap at the end of the steel hoop, ultimately forming a complete sealing ring with the other end of the steel hoop.
[0035] After the initial sealing is completed, the operator applies a 5-Newton pull downwards by gripping the control handle, causing the elliptical component to move the rotating post outwards by 3 mm, overcoming the resistance of the return spring made of 65Mn spring steel. The elliptical component is then rotated 15 degrees, aligning the 6 mm diameter insertion post with the insertion slot on the side of the barrel, guided by the limiting point. Releasing the control handle causes the return spring to push the insertion post precisely into the insertion slot, forming a mechanical interlock. At this point, the positioning arc plate disengages from the recessed groove of the clamping handle, and its POM material surface makes smooth contact with the guide arc surface.
[0036] Tests showed that, under accelerated testing conditions of 40°C and 75% relative humidity, the moisture content of kudzu polysaccharides stored in this container increased only from the initial 5.3% to 5.8% after 180 days, far lower than the 7.2% of samples stored in traditional containers. In simulated transport vibration tests, the fixing module remained locked after 2000 vibration cycles, and the opening pressure of the clamping handle remained above 50 Newtons. This sealing structure effectively ensures the quality stability of kudzu polysaccharides within a 24-month shelf life, enabling the product to meet the food preservation standards for export to the European Union.
[0037] The working principle of this utility model: Step 1: Cover the barrel 1 containing the inner bag of kudzu polysaccharide with the barrel lid 101. The operator holds the clamping handle 103 and pulls it towards the center of the barrel lid 101. This action tightens the steel hoop 102 through the end shaft 104, so that the steel hoop 102 tightens the joint between the barrel lid 101 and the barrel 1, achieving initial sealing and fixation.
[0038] Step 2: During the process of turning the clamping handle 103, the driven gear 201 fixed on the end shaft 104 rotates accordingly.
[0039] The driven gear 201 meshes with the tooth groove 205 on the inner circumferential surface of the U-shaped tooth 204. Therefore, the rotation of the gear drives the entire U-shaped tooth 204 to slide along the pre-set arc groove 206 on the steel hoop 102.
[0040] The U-shaped toothed component 204 drives the U-shaped arc component 202 to move synchronously via the T-shaped limiting component 203. The sliding of the T-shaped limiting component 203 within the arc groove 206 ensures the stability and precision of the movement trajectory.
[0041] As the clamping handle 103 closes, the U-shaped arc 202 is precisely pushed to the opening gap at both ends of the steel hoop 102. Its unique arc structure perfectly fills this traditional physical gap, forming a complete and continuous sealing ring together with the main body of the steel hoop 102.
[0042] The tapered end 3 and rounded edge design of the U-shaped arc component 202 ensure smooth insertion and docking, preventing interference or scratches with the barrel 1 or other components. Simultaneously, the shielding arc plate 6 fixed to it moves along with it, always maintaining a tight fit against the outer circumference of the steel hoop 102, concealing any gaps exposed after the movement of the arc groove 206, further enhancing dust and moisture protection.
[0043] Step 3: After the clamping handle 103 is pulled to the fully locked position, the operator needs to activate the fixing module 5 to achieve mechanical interlock.
[0044] The operator grasps the control handle 7 and pulls it downwards, causing the elliptical component 503 and the rotating column 501 to move outwards against the elastic force of the return spring 502. The engagement of the large-diameter plate 8 with the limiting groove 801 limits the maximum stroke of the pull-out. At this time, the positioning arc plate 9 disengages from the embedded arc groove 901, and its guiding arc surface 902 makes the disengagement action smoother.
[0045] In the pulled-out state, the elliptical part 503 is rotated around the pivot 501, so that the insertion pin 504, guided by the limiting point 802, is aligned with the insertion slot 505 provided on the clamping handle 103 or adjacent parts.
[0046] After alignment, release the control handle 7. The reset spring 502 releases its elastic potential energy, quickly pulling back the rotating column 501 and the entire linkage mechanism, driving the insertion pin 504 to accurately insert into the insertion slot 505.
[0047] This locking action forms a robust mechanical lock, physically preventing the clamping handle 103 from rebounding and opening due to vibration or accidental impact, thus ensuring the long-term stability of the sealing pressure.
