Description

Technical Field

[0001] This invention relates to the field of thermos cup processing technology, specifically to a threadless cup and its manufacturing method. Background Technology

[0002] During the production of thermos cups, their heat preservation performance needs to be tested after the product is manufactured to distinguish between good and bad products, and to remove the bad products. The principle of testing the heat preservation performance of thermos cups is to heat and keep the outer (or inner) wall of the thermos cup at a certain temperature, and then measure the temperature of the inner (or outer) wall of the thermos cup after a period of time. The temperature difference between the inner and outer walls of the thermos cup is then compared to evaluate the heat preservation performance of the thermos cup.

[0003] Chinese Patent Publication No. CN 215953428 U provides a vision-based detection device for the heat preservation performance of thermos cups, belonging to the technical field of detection devices. The detection device includes a control cabinet and a rotating platform and a mounting bracket located on the upper part of the control cabinet. The rotating platform has multiple thermos cup placement holes, and heating elements and heat insulation cotton are installed in the thermos cup placement holes. A first vision detection camera and a second vision detection camera are installed on the mounting bracket.

[0004] In the aforementioned patent, when testing a thermos cup, the cup is placed over the cup's placement hole, and a heating element is used to heat the inside of the cup. This thermos cup testing device has the following problems: 1. The turntable has multiple testing stations, requiring a heating element to be placed in each cup's placement hole. Because the turntable rotates indefinitely, the wiring for the heating elements is difficult to route, easily leading to breakage and damage. 2. The heating speed of the heating element is slow, while the turntable's rotation speed is constant. This results in insufficient time for the thermos cup to heat up, or insufficient time for testing after heating, leading to inaccurate test results. 3. The thermos cup is simply placed over the placement hole; there is no sealing effect, making it easy for heat to escape, thus reducing the accuracy of the insulation test. Summary of the Invention

[0051] A threadless cup includes an insulated cup inner liner 110, an insulated cup outer shell 109, and a sealing assembly, wherein the insulated cup inner liner 110 is located inside the insulated cup outer shell 109;

[0052] The sealing assembly includes an outer cover 108, a fixed base 104, a button 112, a movable bracket 102, a water-sealing silicone 103, and a spring-loaded component. The outer cover 108 is located on the outer shell 109 of the thermos cup. The fixed base 104 is fixedly disposed inside the outer cover 108. The button 112 is reciprocally disposed above the fixed base 104. The movable bracket 102 can reciprocate on the fixed base 104. The upper end of the water-sealing silicone 103 is fixedly connected to the fixed base 104, and the lower end of the water-sealing silicone 103 is fixedly connected to the outer peripheral wall of the movable bracket 102. The spring-loaded component is disposed on the fixed base 104.

[0053] The spring-loaded component includes a snap-fit ​​spring 107 and a snap-fit ​​106. The snap-fit ​​spring 107 is fixedly connected to the fixed base 104 and is located on one side of the fixed base 104. The snap-fit ​​106 is fixedly connected to the snap-fit ​​spring 107 and is located on one side of the snap-fit ​​spring 107.

[0054] The sealing assembly also includes a limiting ring 105, which is rotatably connected to the outer cover 108 and is located on the side of the outer cover 108 near the button 112.

[0055] The sealing assembly also includes a venting silicone 101, which is fixedly connected to the fixing seat 104 and located on the side of the fixing seat 104 near the movable bracket 102.

[0056] The screwless cup also includes an anti-slip rubber base 111, which is fixedly connected to the outer shell 109 of the thermos cup and located on one side of the outer shell 109 of the thermos cup.

[0057] Furthermore, please refer to the appendix. Figure 14 The limiting ring 105 has multiple protrusions F, which are arranged in a ring array along the limiting ring 105 and are correspondingly slidably connected to the arc-shaped groove on the top of the outer cover 108. The protrusions F on the limiting ring 105 can slide in the arc-shaped groove. When the protrusion F rotates to point b, the button 112 has a space for movement, allowing the button 112 to move up and down. When the protrusion F rotates to point a, the protrusion F on the limiting ring 105 is in a locked state, and the button 112 cannot be activated.

[0058] In this invention, when it is necessary to seal the thermos cup shell 109, the outer cap 108 is pressed downwards. Then, under the contact between the side wall of the thermos cup shell 109's opening and the movable support 102, the movable support 102 is pushed upwards. The movable support 102 moves upwards along with the sealing silicone 103, thereby increasing the diameter of the sealing silicone 103. This sealing silicone 103 then blocks the opening of the cup, thus enabling a quick seal at the opening of the thermos cup shell 109 (e.g., ...). Figure 13 );

[0059] When opening is required, pressing button 112 causes it to move downwards and pushes latches 106 to the sides. After both latches 106 move to the sides, the middle of the latches 106 will also move out of the through hole of the movable bracket 102. Then, the outer cover 108 and the fixed base 104 are lifted upwards together. Without the latches 106 limiting the movement, the movable bracket 102 will reset downwards under the action of the sealing silicone 103, thereby reducing the diameter of the sealing silicone 103, making it easier to remove the bottle cap from the mouth of the cup (e.g., Figure 16 (As shown).

[0060] Finally, the venting silicone 110 is fixedly connected to the fixed base 105 and located on the side of the fixed base 105 near the movable bracket 107. The venting silicone 110 is adhered to the fixed base 105 and can block the air holes of the movable bracket 107. When the button 106 is pressed, the movable bracket 107 moves under the reset action of the sealing silicone 103, and the air holes of the movable bracket 107 are opened, so that the gas in the cup body 101 can be discharged through the air holes on the movable bracket 107, thereby reducing the air pressure in the cup body 101.

[0061] A method for preparing a screwless cup includes the following steps:

[0062] S1. Purchase or manufacture (or produce) buttons 112, buckles, outer covers, limit rings, fixing bases, venting silicone, movable brackets, buckle springs, thermos cup shells, water-sealing silicone, venting silicone, thermos cup inner liner, and anti-slip rubber bottoms.

[0063] S2. Assembly of the thermos cup body: The inner liner of the thermos cup is installed inside the outer shell by welding the inner liner to the outer shell of the thermos cup. The anti-slip rubber bottom is installed on the bottom of the outer shell of the thermos cup by glue.

[0064] S3. Assemble the thermos cup lid: Place the buckle spring into the buckle hole, and fix the buckle as a whole through the slot on the top of the fixing base, so that the buckle can be limited to reciprocating within the slot. Insert the venting silicone into the cylindrical slot of the fixing base, with the venting silicone located directly above the vent hole of the movable bracket. Rotatably lock the limiting ring into the outer cover. Insert the button into the outer cover. Fix the fixing base inside the outer cover with screws. Slide the movable bracket onto the fixing base. Insert the upper end of the sealing silicone into the slot on the outer peripheral wall of the fixing base for fixation. Insert the lower end of the sealing silicone into the lower slot of the movable bracket for fixation.

[0065] S4. Attach the lid of the thermos to the body of the thermos and test the sealing performance of the thermos using a sealing test device.

[0066] S5. Test the heat preservation performance of the thermos cup using heat preservation testing equipment;

[0067] S6. Pack the insulated cups that have passed the inspection.

[0068] In this embodiment, step S5 involves testing the heat preservation performance of the thermos cup using a heat preservation testing device. This device includes a housing 1, with a rotating platform 4 fixedly mounted on top of the housing 1. A rotating disk 11 is fixedly mounted on the rotating platform 4, and a housing 5 is provided outside the rotating disk 11, fixed to the housing 1. The rotating disk 11 has multiple sliding grooves arranged in a circular array. A sealing heating element 7 is slidably connected within each groove. The sealing heating element 7 includes a top-load spring 71, a sliding plate 72 above the top-load spring 71, and a rubber seat 73 bonded above the sliding plate 72. An air inlet 75 is located within the rubber seat 73. A cup removal assembly 8 is also fitted to the outside of the sealing heating element 7.

[0069] In this embodiment, a limiting plate is welded onto the inflation nozzle 75, which is located below the sliding plate 72; the lower end of the inflation nozzle 75 is welded and fixed to the lower end of the top force spring 71; an outer ring 74 is provided on the outside of the rubber seat 73; the outer ring 74 is fixed to the rotating disk 11 by bolts.

[0070] Furthermore, a fixing frame 16 is also fixed on the casing 1, and a pressing cylinder 14 is fixed on one side of the fixing frame 16 by bolts; a pressure plate 15 for pressing down the thermos cup is fixed on the cylinder rod of the pressing cylinder 14.

[0071] By adopting the above technical solution, during use, the operator places the thermos upside down on the rubber base 73. As the rotating disk 11 rotates, when the thermos rotates to below the pressure plate 15, the cylinder rod of the pressing cylinder 14 retracts, causing the pressure plate 15 to press down on the thermos. Under the pressure of the thermos, the rubber base 73, together with the sliding plate 72, compresses the top spring 71, causing the inflation nozzle 75 to abut against the top of the conical nozzle 13a. At this time, the sliding plate 72 is in contact with the bottom of the groove opened on the rotating disk 11. The cylinder rod of the pressing cylinder 14 continues to retract, causing the rubber seat 73 to be fully embedded in the mouth of the thermos. At this time, the inflation nozzle 75 extends into the cavity of the thermos after passing through the rubber seat 73. The steam generator delivers high-temperature gas to the thermos through the steam pipe 13 and the inflation nozzle 75, thus heating the thermos. Heating the thermos with high-temperature gas has the advantage of fast heating speed, which meets the required time for thermos testing when the rotating plate speed is constant.

[0072] As further explained, after heating is complete, the cylinder rod of the pressing cylinder 14 extends, and the pressure plate 15 does not press the thermos cup. At this time, the top spring 71 lifts the sliding plate 72 and the rubber seat 73; while the air inlet 75, which is welded to the lower end of the top spring 71, retracts from the rubber seat 73 under the traction of the top spring 71; at this time, the elastic hole at the top of the rubber seat 73 shrinks, which can reduce the loss of heat inside the thermos cup and improve the testing accuracy of the thermos cup.

[0073] In this embodiment, a wireless temperature sensor 9 is bonded to the top of each of the rubber seats 73; the wireless temperature sensor 9 is wirelessly connected to the temperature control display 10; multiple temperature control displays 10 are provided, all of which are embedded in the outside of the frame body 6; the frame body 6 is fixed to the rotating disk 11 by bolts.

[0074] By adopting the above technical solution, while the thermos cup is keeping warm, the wireless temperature sensor 9 will measure the temperature of the thermos cup in real time and transmit the test temperature to the temperature control display 10 for display. The staff can determine the temperature loss of the thermos cup based on the temperature prompt on the temperature control display 10, and thus determine whether the thermos cup is qualified.

[0075] In this embodiment, the cup removal assembly 8 includes a lifting plate 81 with a circular hole and sleeved on the outside of the rubber seat 73; one end of the lifting plate 81 is slidably connected to the sliding column 82, and a hook column 83 is welded to the bottom of the lifting plate 81; the lower end of the hook column 83 extends through to the bottom of the rotating disk 11 and is fitted with a stop 12; a first spring 84 is sleeved on the sliding column 82.

[0076] Specifically, the lower end of the hook head post 83 is provided with a hook bend, in which a latch 85 is fittingly installed; the latch 85 is slidably connected to an L-shaped plate 87, and the L-shaped plate 87 is fixed at the bottom of the rotating disk 11; the latch 85 is arranged in a "double-T" shape, and a second spring 86 is sleeved on the latch 85; the upper surface of the end of the latch 85 that mates with the hook bend is arranged in an arc shape.

[0077] By adopting the above technical solution, when the vacuum cup is pressed down, the cup mouth of the vacuum cup exerts a downward pressure on the lifting plate 81. While being pressed down, the lifting plate 81 compresses the first spring 84, and the bottom of the hook head post 83 presses the latch 85. Since the upper surface of the end of the latch 85 that mates with the hook bend is arranged in an arc shape, the latch 85 will compress the second spring 86 and slide to one side at this time; when the groove at the lower end of the hook head post 83 is aligned with the latch 85, the latch 85 is inserted into the groove under the pushing force of the second spring 86 to lock the hook head post 83, preventing the lifting plate 81 from jacking up the vacuum cup.

[0078] The component used in cooperation with the cup disengaging assembly 8 further includes a stopper 12. The stopper 12 includes a circular seat 121 fixed to the upper surface of the cabinet body 1. A support arm 122 is welded on the circular seat 121, and a rubber shifting head 123 for the latch 85 to shift is fixed at the upper end of the support arm 122.

[0079] When the vacuum cup needs to be taken out after the detection is completed, as the rotating disk 11 rotates, when the groove at the lower end of the hook head post 83 rotates to the rubber shifting head 123, the latch 85 will be shifted out of the groove under the blocking of the rubber shifting head 123. At this time, the first spring 84 will jack up the lifting plate 81, and the lifting plate 81 clamped at the cup mouth of the vacuum cup will jack up the vacuum cup, so that the vacuum cup can be disengaged from the rubber seat 73, which is convenient for the staff to take down the vacuum cup.

[0080] In this embodiment, the bottom of the inflation nozzle 75 is connected to a tapered nozzle 13a, and the tapered nozzle 13a is fittingly installed on the steam pipe 13; the steam pipe 13 is a stainless steel pipe, which is fixed above the cabinet body 1 through a pipe clamp; the other end of the steam pipe 13 is connected to a steam generator; the steam generator is arranged in the cabinet body 1.

[0081] Heating the vacuum cup through the steam generator has the advantage of fast heating speed, and meets the time required for the vacuum cup test under the condition that the rotating speed of the rotating disk is constant.

[0082] In this embodiment, the lower end of the rotating table 4 is fittingly installed on the speed reducer 3, the speed reducer 3 is fixedly installed in the cabinet body 1, and the speed reducer 3 is further in transmission connection with the servo motor 2.

[0083] The working principle of the present invention is as follows,

[0084] In this invention, during use, the operator places the thermos upside down on the rubber base 73. As the rotating disk 11 rotates, when the thermos rotates to below the pressure plate 15, the cylinder rod of the pressing cylinder 14 retracts, causing the pressure plate 15 to press down on the thermos. Under the pressure of the thermos, the rubber base 73, together with the sliding plate 72, compresses the top spring 71, causing the inflation nozzle 75 to abut against the top of the conical nozzle 13a. At this time, the sliding plate 72 is already in contact with the bottom of the groove on the rotating disk 11, and no longer... The cylinder moves downward; while the cylinder rod of the pressing cylinder 14 continues to retract, causing the rubber seat 73 to be fully embedded in the mouth of the thermos cup. At this time, the inflation nozzle 75 extends into the cavity of the thermos cup after passing through the rubber seat 73. The steam generator delivers high-temperature gas to the thermos cup through the steam pipe 13 and the inflation nozzle 75, thereby heating the thermos cup. Heating the thermos cup by means of high-temperature gas heating has the advantage of fast heating speed. Under the condition that the speed of the rotating plate is constant, it meets the time required for testing the thermos cup.

[0085] After heating is complete, the cylinder rod of the pressing cylinder 14 extends, and the pressure plate 15 no longer presses the thermos cup. At this time, the top force spring 71 lifts the sliding plate 72 and the rubber seat 73. The air inlet 75, which is welded to the lower end of the top force spring 71, retracts from the rubber seat 73 under the traction of the top force spring 71. At this time, the elastic hole at the top of the rubber seat 73 shrinks, which can reduce the loss of heat inside the thermos cup and improve the testing accuracy of the thermos cup.

[0086] While the thermos keeps the contents warm, the wireless temperature sensor 9 measures the temperature of the thermos in real time and transmits the measured temperature to the temperature control display 10. Staff can then determine the temperature loss of the thermos based on the temperature display 10, thereby determining whether the thermos is qualified.

[0087] When the thermos cup needs to be removed after inspection, as the rotating disk 11 rotates, when the groove at the lower end of the hook post 83 rotates to the rubber dial 123, the pin 85 will be pulled out of the groove by the rubber dial 123. At this time, the first spring 84 will lift the lifting plate 81, and the lifting plate 81, which is stuck at the mouth of the thermos cup, will lift the thermos cup, thereby detaching the thermos cup from the rubber seat 73, making it easier for the staff to remove the thermos cup.

[0088] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of the present invention based on the above embodiments and make different extensions and variations, but as long as they do not depart from the spirit of the present invention, they are all within the protection scope of the present invention.
