DETAILED DESCRIPTION

[0035] The specific solutions and specific embodiments of the present invention are further described in conjunction with the accompanying drawings, to make the technical solutions clearer.

Example 1

[0036] As shown in FIG. 1a-1d, this example discloses a quick uncapping structure, comprising a cover body; the cover body comprises a cover 2, an elastic sealing ring 21, an annular guide piece 22, a guide rod 23 and a lever 24. The guide rod 23 comprises a supporting bottom plate 231 and a vertical rod 232; the vertical rod 232 penetrates through a center hole of the cover 2 to be rotationally connected with the external lever 24 of the cover 2; the annular guide piece 22 is sleeved on the vertical rod 232 and the upper end is in contact with the top surface of the cover 2; the elastic sealing ring 21 is sleeved on the vertical rod 232 and the upper end is in contact with the lower end of the annular guide piece 22, the bottom surface of the elastic sealing ring 21 is in contact with the supporting bottom plate 231;

[0037] The inner wall of a cover 2 makes contact with the outer wall of a drinking opening 12 of a main body 1 for accommodating liquid; the inner wall of the drinking opening 12 is provided with a concave elastomer deformation accommodating area 3; the elastomer deformation accommodating area 3 is annular and is used for accommodating an annular elastic sealing ring 21; and when a lever 24 is rotated to a locking state, a guide rod 23 is driven to move upwards to compress the elastic sealing ring 21 to deform and enter the elastomer deformation accommodating area 3 to be in a sealed state.

[0038] In a first example, the elastic sealing ring 21 and an annular guide piece 22 are in a conventional cylindrical shape, and holes are formed in the middle parts of the elastic sealing ring and the annular guide piece and used for installing a vertical rod 232.

[0039] In a second example, a first limiting part 221 is arranged on the lower end face of the annular guide piece 22; a second limiting part 211 is arranged on the upper end face of the elastic scaling ring 21; and when the elastic sealing ring 21 and the annular guide piece 22 are sleeved on the vertical rod 232 after the holes are formed in the middle parts, the first limiting part 221 and the second limiting part 211 are matched to limit movement between the elastic sealing ring 21 and the annular guide piece 22. As shown in FIGS. 1a-1c, the first limiting part 221 adopts a single convex block (or a circular convex ring), the second limiting part 211 adopts a single groove (or a circular groove), and the convex block (or the circular convex ring) is embedded in the groove (or circular groove) to realize limiting between the elastic sealing ring 21 and the annular guide piece 22. Or as shown in FIG. 4, the first limiting part 221 adopts a single groove (or a circular groove), the second limiting part 211 adopts a single convex block (or a circular convex ring), and the single convex block (or the circular convex ring) is embedded in the single groove (or the circular groove) to realize limiting between the elastic sealing ring 21 and the annular guide piece 22.

[0040] The matched grooves and convex blocks can be set as single or multiple distributed along the peripheries of the upper and lower end faces; and the matched circular grooves and circular convex rings can be set as single circles or multiple circles concentrically distributed along the peripheries of the upper and lower end faces.

[0041] In this example, a through hole is formed in the top of the vertical rod 232, and a pin shaft 5 penetrates through the lever 24 and the through hole to complete assembling of the vertical rod 232 and the lever 24. The lever 24 in the example is in an L shape; a connecting part 241 at one end of the lever 24 is rotationally connected with the vertical rod 232 through the pin shaft 5; and by pressing a pressing part 242 at the other end, the lever 24 does not make contact with the cover 2 in the opening state as shown in FIG. 1a; and in the sealing state, the L-shaped lever 24 is rotated around the pin shaft 5 till the inner wall of the lever 24 is attached to the upper surface and the side wall of the cover 2 to reach the locking state. In the rotating process of the lever 24, the vertical rod 232 and a supporting bottom plate 231 are driven to move upwards, and then the annular guide piece 22 and the elastic sealing ring 21 are driven to move upwards; because the distance between the inner top face of the cover 2 and the supporting bottom plate 231 is continuously decreased, the annular guide piece 22 is made of hard materials and does not deform, the elastic sealing ring 21 has elasticity and is pressed to generate transverse deformation, the inner side and the outer side of the elastic sealing ring 21 transversely extrude the inner walls of the vertical rod 232 and the drinking opening 12, and finally an effective sealing state is formed.

[0042] The elastic sealing ring 21 is made of silica gel, rubber or various existing elastic plastic materials. When the lever 24 is opened and turned upwards, the whole lever 24 is tilted above the cover 2, the elastic sealing ring 21 is in an elastic recovering and releasing state and does not make contact with the inner wall of the drinking opening 12, and sealing is not realized, so that a cover body can be quickly opened. When the guide rod 23 is tensioned upwards through the lever 24, the elastic sealing ring 21 is in a compressed state, the materials such as the silica gel of the transversely-deformed elastic sealing ring are squeezed into the elastomer deformation accommodating area 3 to make contact with the inner wall of the drinking opening 12 in a jacking and abutting mode, and thus the sealing effect is achieved through deformation of the materials; and the lever is used for controlling the elastic sealing ring to be compressed and released to seal the main body or release sealing so that a purpose of quickly opening the cover body can be directly achieved.

[0043] In this example, the outer wall of the elastic sealing ring 21 is an arc-shaped face or a straight face.

[0044] The outer wall of the annular guide piece 22 is in clearance fit with the inner wall of the drinking opening 12, and the inner diameter of the drinking opening 12 is about 0.2-0.5 mm larger than the outer diameter of the annular guide piece 22. Specifically, an annular flange 121 is arranged on the inner wall of the drinking opening 12; and when the quick uncapping structure is assembled to the main body 1, the outer wall of the annular guide piece 22 is in clearance fit with the surface of the annular flange 121.

[0045] The example also provides a container, which comprises the quick uncapping structure and a main body 1 for accommodating liquid. The outer wall of the lower end of the drinking opening 12 is provided with a boss 11, and the lower end face of the cover 2 makes contact with the boss 11 in a jacking and abutting mode when the cover 2 covers the drinking opening 12.

[0046] In this example, the bottom of the main body 1 adopts a plane or a plane of which the center is arched upwards. The main body 1 can be of a single-layer or double-layer structure, and vacuum can be designed between the inner layer and the outer layer of the double-layer structure to be used as a vacuum cup.

[0047] In a specific example, the container also comprises a connecting belt 4, and two ends of the connecting belt 4 are connected to the outer wall of the main body 1 and the outer wall of the cover 2 respectively, particularly connected to the side wall (or the top) of the cover 2.

[0048] Preferably, a connecting part of the connecting belt 4 and the cover 2 is in the direction opposite to the rotating direction of the lever 24, and interference is not formed so as to facilitate use.

[0049] The main body 1 adopts the shapes of various conventional containers such as a bottle body, a tank body and a cup.

[0050] In this example, the guide rod can adopt a structure integrally formed by the abovementioned supporting bottom plate 231 and the vertical rod 232, and also can adopt an assembly structure shown in FIGS. 3a and 3b. As shown in FIG. 3a and FIG. 3b, the guide rod 23 comprises the supporting bottom plate 231, the vertical rod 232 and a connecting screw 233; and the connecting screw 233 passes through the lower part of the supporting bottom plate 231 and extends into a hole below the vertical rod 232 to be fixed. A through hole 232b in the top of the vertical rod 232 is used for mounting the pin shaft 5.

Example 2

[0051] Different from the Example 1, as shown in FIGS. 2a-2c, the quick uncapping structure in this example is characterized in that, a groove 25 is formed in the outer top face of the cover; a clamping groove 251 is formed in the inner wall of the groove 25; in this example, the lever 24 is rotated around the pin shaft 5; the lower end of the lever 24 is positioned in the groove 25; and a protruding part 243 positioned between the pressing part 242 and the connecting part 241 is embedded in the clamping groove 251 to lock the lever 24 on the cover 2.

[0052] In this example, the quick uncapping structure further comprises a gasket 6 arranged in an accommodating groove 252 in the center of the groove 25; the vertical rod 232 penetrates through the center hole of the cover 2 and the gasket 6, and is connected to the connecting part 241 of the lever through the pin shaft 5; and the lever 24 can be rotated around the pin shaft 5.

[0053] In one example, as the gasket 6, the annular guide piece 22 and the elastic sealing ring 21 sleeve the vertical rod 232 in sequence from top to bottom, and the upper end of the elastic sealing ring 21 is assembled with the lower end of the annular guide piece 22, in order to achieve axial installation and positioning, a guide bar 232a is longitudinally arranged at the outer periphery of the vertical rod 232; gaps 61 are respectively formed in the through holes in the centers of the gasket 6 and the annular guide piece 22; and when the vertical rod 232 penetrates through the annular guide piece 22 and the gasket 6 for assembling, the guide bar 232a penetrates through the gap of the annular guide piece 22, the gap of the center hole of the cover 1 and the gap 61 of the gasket 6 to finish directional accurate assembling.

[0054] In this example, two ends of the connecting belt 4 are respectively connected to the outer wall of the main body 1 and the outer top face of the cover 2.
