Description

[Technical field]

[0001] The present application relates to the technical field of sealing thermal insulation cups, and in particular to a screwless press-type thermal insulation cup. [Background technology]

[0002] The sealed thermal cup is a container designed to retain the temperature of liquid (hot or cold), and features excellent sealing performance and thermal insulation effect. In order to meet consumer demand, the structural design of the thermal cup is gradually updated and optimized with the development of technology.

[0003] In the design of traditional thermal cups, the screw cap is the most common sealing method. This design requires the user to rotate the cup cap to achieve opening and closing. A Chinese utility model with registration number CN220713601U discloses a non-screw thermal cup, which includes a cup body and a cup lid, and the cup lid includes a lid body, a lifting material, a sealing material, a trigger, a locking material, a first spring, a second spring, a transmission material, and a sealing lid. When used, the lifting material is pulled up, and the locking material is inserted into the lifting material by the second spring to achieve the locking of the lifting material, at this time, the sealing material is deformed by the lifting material to seal and abut the cup body. When it is necessary to open, the trigger is pressed down, and the locking material is separated from the lifting material by the guide part, the pressure is released, and the lifting material is reset upward by the first spring, at this time, the sealing material restores its deformation and no longer plays a sealing role.

[0004] In contrast to the above-mentioned related art, the cup lid in the cited document is unlocked by a pulling operation, so there are two unlocking methods when removing the cup lid. In one method, it is operated with both hands, one hand pulls up the pull-up material, and the other hand presses the cup body. In the other method, it is operated with one hand, one finger pulls up the trigger, and two fingers press the lid body. Since the above two cup lid unlocking methods are relatively complicated, the present application provides a screw-free thermal cup that is easy to attach and detach.

The cup cap 6 is connected and fixed to the biasing assembly 5, and the unlocking drive member 7 and the position restricting assembly 8 are both provided on the cup cap 6. The locking of the biasing assembly 5 and the locking member 3 is achieved by pressing the cup cap 6, and the unlocking of both is achieved by pressing the unlocking drive member 7. The position restricting assembly 8 is used to limit the pressing of the unlocking drive member 7 to prevent erroneous contact.

[0037] 2 and 3, the locking member 3 includes a first locking ring 31 and a second locking ring 32, and the first locking ring 31 and the second locking ring 32 are connected in a sealed manner by screws. The first locking ring 31 has a T-shaped cross section in the axial direction, and includes a first positioning base 311 against which one end of the elastic seal ring 4 abuts, and a screw-fitting pin 312 provided at the top of the first positioning base 311. The first positioning base 311 has a circular cross section in the radial direction, and is disposed coaxially integrally with the screw-fitting pin 312. Toggle operation protrusions 3111 for rotation are provided symmetrically along the axis at the bottom of the first positioning base 311, making it easy to attach and detach the first locking ring 31 and the second locking ring 32.

[0039] 4 and 5, a seal ring groove 3121 is opened in the outer wall of the end of the screw pin 312, and a seal ring 33 is installed in the seal ring groove 3121.

[0040] The elastic seal ring 4 is an elastic rubber cover in the prior art, and both ends of the elastic seal ring 4 abut against the first positioning block 311 and the second positioning block 321, respectively. The bottom end surface of the threaded sleeve 322 further has an attachment ring groove 3222 into which one end of the elastic seal ring 4 is engaged while being positionally regulated. One side of the elastic seal ring 4 close to the first positioning block 311 has an elastic deformation part 41, and the elastic deformation part 41 as a whole is in the shape of a truncated cone. The outer wall of the threaded sleeve 322 has a positioning surface 3221 with which the top wall of the elastic deformation part 41 abuts, and further has a distortion gap 42 between the elastic deformation part 41 and the outer wall of the second lock ring 32, so that when the biasing assembly 5 moves toward the locking material 3, the elastic deformation part 41 as a whole expands and distorts outward, driving it to be sealed and engaged with the inner wall of the cup body 2, and realizing the fixing and sealing of the cup lid 1 and the cup body 2.

[0041] The top side of the second lock ring 32 facing the biasing assembly 5 has a mounting groove 323, and the mounting groove 323 and the screw pin 312 are arranged coaxially. A positioning pin 324 is integrally and coaxially provided on the bottom wall of the mounting groove 323 of the second lock ring 32, and a first elastic member 34 is fitted onto the positioning pin 324. The radial cross section of the positioning pin 324 is circular, and its outer diameter is smaller than the inner diameter of the mounting groove 323. Two locking grooves 3241 are opened symmetrically along the axis at the end of the positioning pin 324.

[0042] 3, 4 and 6, the biasing assembly 5 includes a biasing ring 51, a biasing block 52 attached to the top of the biasing ring 51 while being positioned in a restricted manner, and a second elastic material 53 connected to the biasing block 52.

[0043] The entire urging ring 51 is disk-shaped, and its outer diameter matches the outer diameter of the second positioning table 321. The distance from the bottom surface of the urging ring 51 to the top surface of the second positioning table 321 is the sliding range of the entire urging assembly 5. A plurality of urging arc-shaped blocks 511 for urging the elastic seal ring 4 in the circumferential direction along the axis are provided on the bottom of the urging ring 51. The second positioning table 321 has urging through holes 3211 that correspond one-to-one to the urging arc-shaped blocks 511 and through which the urging arc-shaped blocks 511 pass. An engaging arc-shaped block 5111 that is engaged with the second lock ring 32 is provided on the urging arc-shaped block 511 and extends toward the first lock ring 31, and the engaging arc-shaped block 5111 slides on the side wall of the screw-engagement sleeve 322 while being positionally restricted. In this embodiment, the biasing ring 51 has four biasing arcuate blocks 511 that are uniformly spaced apart in the circumferential direction.

[0044] A positioning sleeve 512 fitted onto the positioning pin 324 is provided integrally on the central axis of the bottom of the urging ring 51. The axial length of the positioning sleeve 512 matches the length of the sliding gap, so that the positioning sleeve 512 is always fitted onto and matches the positioning pin 324 when the urging assembly 5 is in the locked or unlocked state. The inner diameter of the first elastic member 34 is larger than the outer diameter of the positioning sleeve 512, and both ends of the first elastic member 34 abut against the bottom surface of the urging ring 51 and the bottom wall of the mounting groove 323, respectively.

[0045] The urging ring 51 has lock through-holes 513 that penetrate both end faces and correspond to the positioning pins 324. The urging assembly 5 has two urging blocks 52 that are attached to the urging ring 51 while sliding in the radial direction. The top surface of the urging ring 51 has a position restriction block 514 to which the urging blocks 52 are attached and positionally restricted, and an abutment block 515 with which one end of the second elastic member 53 abuts.

[0046] The ends of the two urging blocks 52 facing the lock through hole 513 each have a lock block 521 for insertion into the lock groove 3241, and one side of the urging block 52 away from the lock block 521 has an abutment groove 522 with which the other end of the second elastic material 53 abuts. Both ends of the second elastic material 53 abut against the abutment block 515 and the bottom wall of the abutment groove 522, respectively. In the normal state of the second elastic material 53, the lock block 521 corresponds to the lock through hole 513. In this embodiment, the first elastic material 34 and the second elastic material 53 are both spring materials of the prior art.

[0047] 4, 5 and 6, the bottom of the lock block 521 facing the lock through hole 513 further has a first lock arc surface 5211. The end of the positioning pin 324 has a second lock arc surface 3242 matching the first lock arc surface 5211, and the bottom wall of the second lock arc surface 3242 facing the mounting groove 323 extends below the lock groove 3241, so that when the user presses the biasing ring 51 to lock it, the positioning pin 324 drives the two biasing blocks 52 to move in directions away from each other.

[0048] The cup cap 6 is covered by the biasing ring 51, and the axial length of the cup cap 6 is greater than the distance from the biasing ring 51 to the second positioning stand 321, so that the inner wall of the cup cap 6 corresponds to the second positioning stand 321 in both the locked and unlocked states of the biasing assembly 5.

[0049] 7 and 8, the cup cap 6 is inserted and fixed into the urging ring 51, both sides of the urging block 52 on the top surface of the urging ring 51 have a number of insertion pins 516, and the inner top wall of the cup cap 6 has an insertion cover 61 that corresponds to and matches the insertion pins 516. The top of the cup cap 6 has a sliding groove 62 in which the unlocking driving member 7 is attached. The sliding groove 62 is a circular groove, and the bottom wall has an unlocking through hole 621 that communicates with the urging ring 51. The unlocking through hole 621 and the positioning pin 324 are coaxially arranged.

[0050] The unlocking drive member 7 includes an unlocking button 71 and an unlocking piece 72 provided at the bottom of the unlocking button 71 and adapted to abut against the biasing block 52. The biasing block 52 has an unlocking block 523 corresponding to the unlocking piece 72 on both sides toward the end of the lock through-hole 513. Here, the lock block 521 is located between the unlocking blocks 523, and the distance between the corresponding unlocking blocks 523 of the two biasing blocks 52 in the unlocked state is smaller than the distance between the two lock blocks 521. The unlocking block 523 has a first unlocking arc surface 5231 provided on one side toward the cup cap 6, and the unlocking piece 72 has a second unlocking arc surface 721 matching the first unlocking arc surface 5231, so that when the user presses the unlocking drive member 7, the two biasing blocks 52 can be moved away from each other more easily.

[0051] The position restriction assembly 8 includes a position restriction ring 81 rotatably provided in the sliding groove 62, and an elastic plug material 82 for locking and matching with the position restriction ring 81. The cup cap 6 further has a rotation through hole 63 horizontally communicating with the outside on the side wall of the sliding groove 62, and a toggle operation block 83 extending outside the rotation through hole 63 is attached to the position restriction ring 81. The toggle operation block 83 is engaged and matched with the position restriction ring 81, and both sides of the end of the toggle operation block 83 have two engaging blocks 831. The engaging block 831 has a certain degree of elastic deformation performance. The position restriction ring 81 has an engaging groove 811 with which the engaging block 831 is elastically engaged.

[0052] The horizontal radians of the pivot through hole 63 is the pivot range of the position restriction ring 81. The bottom of one end of the position restriction ring 81 away from the toggle operation block 83 has two lock holes 812, which are spaced apart in the circumferential direction along the axis. The elastic plug material 82 is consistent with the spring plug structure of the prior art and is arranged corresponding to the lock holes 812. By pivoting the toggle operation block 83 back and forth, the two lock holes 812 are matched up with the plug heads in turn.

[0053] The position restriction ring 81 has a position restriction arrangement groove 813 that penetrates both upper and lower end faces and in which the unlock button 71 is arranged. A plurality of pressing position restriction portions 711 are provided at intervals in the circumferential direction of the outer wall of the unlock button 71. The pressing position restriction portions 711 and the unlock button 71 are integrally molded and arranged to extend along the radial direction. The position restriction arrangement groove 813 of the position restriction ring 81 is provided with a position restriction lock groove 814 that corresponds one-to-one to the pressing position restriction portions 711. The position restriction lock groove 814 includes a first groove 8141 and a second groove 8142, and the first groove 8141 penetrates and communicates with the top of the position restriction ring 81, and the axial depth of the second groove 8142 is the same as the thickness of the pressing position restriction portion 711.

[0054] After one of the locking holes 812 of the position restricting ring 81 is locked by the elastic plug material 82, the pressing position restricting part 711 corresponds to the first groove 8141, at this time, the unlocking drive material 7 is in an unlocked state and can slide and be pressed in the vertical direction; after the other of the locking holes 812 of the position restricting ring 81 is locked by the elastic plug material 82, the pressing position restricting part 711 corresponds to the second groove 8142, at this time, the pressing position restricting part 711 is restricted in position by the second groove 8142 and cannot slide in the vertical direction; when normally positioned, it can reduce erroneous contact with the unlocking drive material 7 and improve convenience of use.

[0055] The top of the cup cap 6 further has a sealing lid 64 that covers the sliding groove 62, and the sealing lid 64 is sealed and engaged with the inner wall of the sliding groove 62 and is used to reduce the probability of external dust and other contaminants entering the position control ring 81.

[0056] In the second embodiment, except that the cup cap 6 is provided with a handle portion 65, all other structures are the same as those of the first embodiment.

[0057] 9 and 10, in order to easily hold the thermal cup, a handle portion 65 is further provided on the outer wall of the cup cap 6, and the handle portion 65 is located on one side away from the toggle operation block 83. The handle portion 65 is integrally provided on the side wall of the cup cap 6, and the cross section of the handle portion 65 is U-shaped. In another embodiment, the handle portion 65 is provided on the side wall of the cup cap 6 so as to be rotatable.

[0058] The principle of implementation of the screwless press-type sealed heat-retaining cup of the embodiment of the present application is as follows. When attaching the cup lid 1 and the cup body 2, first adjust the positioning pin 324 and the biasing block 52 to the unlocked state, and then insert the cup lid 1 into the cup body 2. The second positioning block 321 abuts against the open end surface of the cup body 2 while positioning it, and biases the cup cap 6 and the biasing assembly 5 downward. Due to the matching between the first locking arc surface 5211 and the second locking arc surface 3242, the positioning pin 324 passes through the locking through hole 513, and the locking block 521 corresponds to the locking groove 3241. Then, the second elastic material 53 automatically inserts the locking block 521 into the locking groove 3241 to lock the positioning pin 324 and the biasing ring 51. At the same time, the biasing arc block 511 biases the elastic sealing ring 4 downward, causing the elastic deformation part 41 to expand and engage between the first positioning block 311 and the inner wall of the cup body 2.

[0059] When it is necessary to release the lock, first, rotate the toggle operation block 83 to drive the position control ring 81 to rotate, adjust the pressing position control portion 711, the first groove 8141 and the unlocking drive member 7 to the unlocked state, and then press the unlocking drive member 7 downward, so that the unlocking piece 72 abuts against the unlocking block 523 through the unlocking through hole 621 and continues to press, driving the lock block 521 to separate from the lock groove 3241 by the first unlocking arc surface 5231 and the second unlocking arc surface 721, loosening the unlocking drive member 7, and the cup cap 6 and the biasing ring 51 are automatically reset upward by the first elastic material 34, realizing the lock between the positioning pin 324 and the biasing ring 51, and the elastic sealing ring 4 also restores its distortion, and at this time, the cup lid 1 can be removed from the cup body 2.

[0060] The above are preferred embodiments of the present application, and do not limit the scope of protection of the present application, so that any equivalent changes made based on the structure, shape, and principle of the present application shall be covered by the scope of protection of the present application.
