[0030] Example 1

[0031] This embodiment provides a press-type sealing cap for sealing the opening of a container. Referring to Figures 1 and 2, the press-type sealing cap includes a face cover 1, a bottom cover 2, a pressing element 3, a sealing element 4, and a transmission mechanism 5. The face cover 1 and the bottom cover 2 are movably disposed relative to each other. The pressing element 3 is slidably disposed on the face cover 1 along the axial direction. The sealing element 4 is disposed on the bottom cover 2. The transmission mechanism 5 is disposed between the face cover 1 and the bottom cover 2, with one end of the transmission mechanism 5 connected to the pressing element 3 and the other end connected to the bottom cover 2. Pressing the pressing element 3 drives the transmission mechanism 5 to move the bottom cover 2 axially relative to the face cover 1, thereby moving the sealing element 4 and sealing the gap between the face cover 1 and the container body through the sealing element 4.

[0032] The top cover 1 and the bottom cover 2 are in a relatively movable state, and are arranged opposite each other along the axial direction. Referring to Figure 2, the upper surface of the top cover 1 is recessed downward to form a first recessed cavity 11, and the pressing member 3 is movably installed in the first recessed cavity 11, and the pressing member 3 can move axially. The outer peripheral surface of the bottom cover 2 is provided with an annular mounting groove 21, and the sealing member 4 is installed in the mounting groove 21.

[0033] Referring to Figure 3, the pressing component 3 includes a pressing base 31 and a pressing guide 32. The pressing base 31 is cap-shaped, and the pressing guide 32 is connected to the lower part of the pressing base 31. The pressing base 31 is movably installed in the first recessed cavity 11 and can move relative to the first recessed cavity 11. A guide groove 12 is axially provided on the side wall of the first recessed cavity 11. The pressing guide 32 is movably disposed in the guide groove 12 and moves axially along the guide groove 12, thereby restricting the axial movement of the pressing base 31 relative to the first recessed cavity 11 and preventing the pressing base 31 from detaching. In this embodiment, there are multiple pressing guides 32, and the number of guide grooves 12 is the same as the number of pressing guides 32. The pressing guides 32 correspond one-to-one with the guide grooves 12 and are movably connected. Preferably, the pressing guide 32 is hook-shaped, which not only limits its position but also facilitates its insertion into the guide groove 12.

[0034] Referring to Figure 1, the transmission mechanism 5 includes a transmission component 51 and a locking component 52. One end of the transmission component 51 is linked to the pressing member 3, and the other end of the transmission component 51 is connected to the bottom cover 2. One end of the locking component 52 is connected to the transmission component 51, and the other end of the locking component 52 is movably engaged with the pressing member 3. When the pressing member 3 is pressed, the bottom cover 2 is driven to move axially through the transmission component 51. Simultaneously, the locking component 52 engages or disengages from the pressing member 3 to keep the position of the bottom cover 2 unchanged, thereby keeping the position of the sealing member 4 unchanged and maintaining the open or closed state of the sealing cover.

[0035] The transmission assembly 51 includes a transmission seat 511 and a transmission arm 512. The transmission seat 511 is movably disposed on the outer side of the bottom of the first recessed cavity 11 and is connected to the bottom cover 2. The transmission arm 512 is disposed between the pressing member 3 and the first recessed cavity 11 and is hinged to the transmission seat 511. A transmission spring 513 is also provided between the top cover 1 and the transmission seat 511. One end of the transmission spring 513 abuts against the bottom of the first recessed cavity 11, and the other end of the transmission spring 513 abuts against the transmission seat 511, so that the transmission seat 511 always tends to move away from the top cover 1.

[0036] Specifically, the transmission base 511 includes a transmission base 5111, a first linkage part 5113, and a second linkage part 5114. The first linkage part 5113 and the second linkage part 5114 are disposed on the upper surface of the transmission base 5111. The first linkage part 5113 is used to connect with the transmission arm 512, and the second linkage part 5114 is used to connect with the locking assembly 52. ​​The transmission base 5111 is movably disposed on the outer side of the bottom of the first recess 11. The bottom of the first recess 11 is provided with a first opening 111 and a second opening 112. The first linkage part 5113 is movably inserted into the first opening 111, and the second linkage part 5114 is movably inserted into the second opening 112.

[0037] The outer peripheral surface of the transmission base 5111 is provided with a plurality of transmission connecting portions 5112, and the upper surface of the bottom cover 2 is provided with a bottom cover connecting portion 22. The inner peripheral surface of the bottom cover connecting portion 22 is provided with a plurality of bottom cover connecting positions 221. The transmission connecting portions 5112 correspond one-to-one with the bottom cover connecting positions 221, and the corresponding transmission connecting portions 5112 are screwed to the bottom cover connecting positions 221, thereby fixing the bottom cover 2 to the transmission base 511. The transmission base 511 drives the bottom cover 2 to move. In this embodiment, the transmission base 5111 adopts a disc structure.

[0038] One end of the transmission arm 512 is hinged to the transmission seat 511, while the other end is suspended. The transmission arm 512 can be flipped relative to the transmission seat 511, and when the sealing cover is open, the suspended end of the transmission arm 512 abuts against the inner cavity of the pressing member 3. To assist in the flipping of the transmission arm 512, a slide table 5121 is provided at the bottom of the first recessed cavity 11 and in the inner cavity of the pressing member 3. The end of the transmission arm 512 moves along the surface of the slide table 5121, allowing for smooth and uninterrupted flipping. Furthermore, to improve the reliability of the transmission, two transmission arms 512 are used, arranged symmetrically about the axis of the transmission seat 511 to enhance the transmission stability. Correspondingly, two linkage parts are also used, with each transmission arm 512 hinged to one of the linkage parts.

[0039] Referring to Figures 5 and 6, the locking assembly 52 includes a locking seat 521, a locking latch 522, and a locking reset member 523. The locking seat 521 is mounted on the second linkage part 5114, so that the locking seat 521 moves synchronously with the transmission seat 511. The locking latch 522 is movably disposed in the locking seat 521, and a reset spring 524 is provided between the locking seat 521 and the locking latch 522, so that the locking latch 522 always has an upward tendency to move. The first end 5231 of the locking reset member 523 is linked with the locking latch 522, and the second end 5232 of the locking reset member 523 moves along the locking reset channel 5212 of the locking seat 521.

[0040] Specifically, the locking seat 521 has a limiting groove 5211 on its side and the locking fastener 522 has a limiting part 5221 on its side. The limiting part 5221 moves along the limiting groove 5211 to limit the range of vertical movement of the locking fastener 522 and prevent the locking fastener 522 from disengaging from the locking seat 521.

[0041] The locking fastener 522 has a connecting hole 5222, and the first end 5231 of the locking reset member 523 is inserted into the connecting hole 5222. The upper part of the first end 5231 of the locking reset member 523 has an irregular surface 5233, and the lower part has an arc-shaped surface 5234. The shape of the connecting hole 5222 matches the shape of the first end 5231 of the locking reset member 523. When the locking fastener 522 moves up and down, it drives the locking reset member 523 to move up and down as well. Simultaneously, the locking reset member 523 can rotate around its first end 5231, allowing the second end 5232 of the locking reset member 523 to enter, exit, or move within the locking reset channel 5212. The locking reset channel 5212 has a locking position 52121. When the second end 5232 of the locking reset member 523 enters the locking position 52121, an external force is required to drive the second end 5232 of the locking reset member 523 to leave the locking position 52121.

[0042] The inner cavity of the pressing base 31 is provided with a fastening part 33, which is disposed opposite to the top of the locking fastening member 522. The top of the locking fastening member 522 is provided with two symmetrically arranged fastening arms 5223. Each fastening arm 5223 is connected to the locking fastening member 522 via a fastening elastic part 5224, giving the two fastening arms a tendency to open, and allowing them to close under external force. When the two fastening arms 5223 are closed, they can engage with the fastening part 33; when the two fastening arms 5223 are open, the fastening part 33 can disengage from the two fastening arms 5223. In this embodiment, the fastening part 33 adopts an inverted trapezoidal structure, the fastening arms 5223 adopt a hook structure, and the cross-section of the fastening elastic part 5224 is U-shaped.

[0043] The opening and closing principle of the sealing cap will be explained next:

[0044] First, the sealing cover is set to the open state. At this time, the fastening part 33 of the pressing member 3 is separated from the locking assembly 52 and is not connected, so that the transmission seat 511 is in an active state. Under the action of the transmission spring 513, the transmission seat 511 moves downward away from the top cover 1, and the bottom cover 2 and the sealing member 4 move accordingly, so that the sealing member 4 is separated from the inner wall of the container. At the same time, when the transmission seat 511 moves downward away from the top cover 1, the transmission arm 512 is driven to move through the first linkage part 5113. After the transmission arm 512 flips upward along the surface of the slide table 5121, the suspended end of the transmission arm 512 continues to press against the pressing member 3 and lifts the pressing member 3.

[0045] When the pressing member 3 is pressed down, it continuously presses against the suspended end of the transmission arm 512, causing the transmission arm 512 to flip downwards. Under the transmission of the first linkage part 5113, the transmission seat 511 moves upwards towards the top cover 1, and the bottom cover 2 and the sealing member 4 move accordingly, so that the sealing member 4 is tightly attached to the inner wall of the container, achieving a seal. At this time, it is in a sealed state. Simultaneously, when the pressing member 3 is pressed down, the fastening part 33 moves downwards and presses against the top of the locking fastening member 522. The locking fastener 522 moves downward, which in turn moves the locking reset 523, causing the second end 5232 of the locking reset 523 to enter the locking position 52121 along the locking reset channel 5212. At this time, the two fastening arms 5223 close under the restriction of the opening of the locking seat 521, so that the two fastening arms 5223 are engaged with the fastening part 33. The positions of the locking seat 521 and the transmission seat 511 are relatively fixed, thereby keeping the position of the sealing element 4 unchanged and maintaining the sealing state.

[0046] When the pressing member 3 is pressed down again, the second end 5232 of the locking reset member 523 leaves the locking position 52121 along the locking reset channel 5212. Under the action of the reset spring 524, the locking fastening member 522 moves upward. At this time, the two fastening arms 5223 are released from the restriction of the opening of the locking seat 521, and the two fastening arms 5223 are separated from the fastening part 33. At this time, the transmission seat 511 is in an active state, and under the action of the transmission spring 513, the transmission seat 511 moves downward away from the top cover 1, and the bottom cover 2 and the sealing member 4 move accordingly, so that the sealing member 4 is separated from the inner wall of the container. At the same time, when the transmission seat 511 moves downward away from the top cover 1, the first linkage part 5113 drives the transmission arm 512 to move, so that the transmission arm 512 flips upward along the surface of the slide table 5121, and the suspended end of the transmission arm 512 continues to press against the pressing member 3 and lifts the pressing member 3, returning to the open state.

[0047] For users, simply pressing the button 3 changes the state of the sealing cover. Opening and closing the cover is simple, easy, and convenient, and can be operated with one hand.

[0048] In addition, the press-type sealing cover also includes a time component 6, which is used to record time. Referring to the figure, the time component 6 includes a time segment 61 and a time counter 62. The time segment 61 is disposed on the cover body 1, and the time counter 62 is movably disposed on the time segment 61. The time counter 62 marks the date on the time segment 61 to record the time.

[0049] Specifically, the time-segment component 61 includes a time-segment portion 611, and a second recessed cavity 13 is provided on the upper surface of the cover body 1, with the time-segment portion 611 disposed on the second recessed cavity 13. At least one time-segment connecting portion 612 is provided on the lower surface of the time-segment portion 611, and at least one recessed cavity connecting portion 131 is provided on the second recessed cavity 13, with the time-segment connecting portion 612 and the recessed cavity connecting portion 131 correspondingly connected. In this embodiment, the second recessed cavity 13 has an annular structure and surrounds the first recessed cavity 11; correspondingly, the time-segment portion 611 has a circular structure. The time-segment connecting portion 612 has a hook structure, and the recessed cavity connecting portion 131 has a through-hole structure. There are three time-segment connecting portions 612, and correspondingly, there are also three recessed cavity connecting portions 131.

[0050] The time period section 611 includes a month segment 6111 and a day segment 6112, with the month segment 6111 and the day segment 6112 connected end to end. There are two timing units 62, one of which is attached to the month segment 6111 and the other is attached to the day segment 6112.
