DETAILED DESCRIPTION

[0030] This disclosure is described below in further detail with reference to accompanying drawings and an embodiment.

Embodiment 1

[0031] This embodiment provides a cover, in particular, it can be used in cooperation with a water container body such as a cup. Referring to FIGS. 1 to 5, the cover of this embodiment comprises a cover base 11, an upper cover 12, a bracket 13, a pressing ring 14 and a button 15.

[0032] The cover base 11 has a first shaft hole 110 and a water outlet 111. The upper cover 12 has a first snap portion 121 and a water blocking member 12 for blocking the water outlet 111. The end of the upper cover 12 has a pair of second shaft holes 120 corresponding to each other, and the second shaft holes 120 and the first shaft hole 110 of the cover base 11 are arranged corresponding to each other. The upper cover 12 is hinged to the cover base 11. Specifically, the hinged connection between the upper cover 12 and the cover base 11 is achieved through a pivot shaft 17 with a torsion spring 161 fitted over the outside passing through the first shaft hole 110 and the second shaft holes 120.

[0033] The bracket 13 is located on the cover base 11 and provided with a set of first rotating shaft holes 130 arranged opposite to each other. The pressing ring 14 has two second rotating shaft holes 140 and a snap-fit portion 141 for snapping the upper cover 12, the snap-fit portion 141 is located at the upper end of the pressing ring 14, the two second shaft holes 140 are located on two opposite sides of the pressing ring 14, and the pressing ring 14 is hinged to the bracket 13 through a pivot shaft 17 passing through the second pivot hole 140 and the first pivot hole 130; a torsion spring 161 serving as a reset elastic member is fitted over the outer side of the pivot shaft 17, one end of the torsion spring 161 is connected to the pressing ring 14, and the other end of the torsion spring 161 is connected to the bracket 13 directly or indirectly.

[0034] The button 15 has an upper end 151, a lower end 152 and a fulcrum (not shown in the figures) between the upper end 151 and the lower end 152. The upper end 151 of the button 15 has a second snap portion 153 that is snap-fitted with the first snap portion 121 of the upper cover 12, and an elastic contact member 150 is formed on the lower end 152. The elastic contact member 150 can be made of an elastic silicone material; wherein the button 15 is arranged on the cover base 11 in a lever manner through the cooperation between the fulcrum and the cover base 11.

[0035] When the pressing ring 14 is turned relative to the bracket 13 and pushes against the lower end 152 of the button 15, a pushing force is applied to the lower end 152 of the button 15 to disengage the second snap portion 153 from the first snap portion 121.

[0036] That is to say, the user can turn the pressing ring 14 with one hand, and the snap-fit portion 141 of the pressing ring 14 is disengaged from the upper cover 12 first, and then continues to turn the pressing ring 14 so that the pressing ring 14 pushes against the lower end 152 of the button 15. The torsion spring 161 will be compressed and deformed due to the movement of the pressing ring 14. Since the button 15 is arranged on the cover base 11 in a lever manner, the elastic contact member 150 on the lower end 152 will push against the cover base 11, and the elastic contact member 150 is also compressed and deformed. Due to the existence of the above-mentioned fulcrum, the upper end 151 of the button 15 moves in a direction opposite to the lower end 152 (i.e., away from the cover base 11), so that the second snap portion 153 of the upper end 151 is disengaged from the first snap portion 121 of the upper cover 12, and then the entire upper cover 12 is completely opened. FIGS. 6, 7 and 8 respectively show the case where the upper cover is disengaged from the pressing ring, the case where the button is disengaged from the upper cover, and the case where the upper cover is fully opened. Since both the torsion spring 161 and the elastic contact member 150 have been compressed and deformed, after the overturning force applied to the pressing ring 14 is removed, the torsion spring 161 will be reset under the action of the elastic resilience, and the elastic contact member 150 will also produce a reset movement until the upper end of the pressing ring 14 and the button 15 return to their original positions again, as shown in FIG. 9 for details. Certainly, the user can perform a reverse operation on the cover with the upper cover opened with one hand, and then the upper cover 12 can close the cover base 11, thus finishing the single-handed cover closing operation for the cover.

[0037] In order to realize the snap fit between the upper cover and the pressing ring and between the upper cover and the button respectively, as shown in FIGS. 3 to 5, in this embodiment, the first snap portion 121 of the upper cover 12 comprises a first step 1211 and a second step 1212, and the second step 1212 is located below the first step 1211. The first step 1211 here is matched with the snap-fit portion 141 of the pressing ring 14 for a snap fit to achieve the snap fit between the upper cover 12 and the pressing ring 14. The second step 1212 is snap-fitted with the second snap portion 153 of the button 15 to achieve the snap fit between the upper cover 12 and the button 15.

[0038] In the process of closing the upper cover, in order to facilitate the upper cover to be able to achieve a snap fit with the pressing ring and the button respectively, referring to FIGS. 3, 4, 8 and 9, in this embodiment, a first guide surface 181 is arranged at the position where the first snap portion 121 comes into contact with the snap-fit portion 141 of the pressing ring 14, and a second guide surface 181 is arranged at the position where the first snap portion 121 comes into contact with the second snap portion 153 of the button 15. For example, the first guide surface 181 may be formed on the first snap portion 121, or may be formed on the snap-fit portion 141 of the pressing ring 14. Certainly, the second guide surface 181 may be formed on the first snap portion 121, or may be formed on the second snap portion 153 of the button 15. By arranging the first guide surface 181, the upper cover 12 can be snap-fitted with the pressing ring 14 more smoothly.

[0039] This embodiment further provides a water container, specifically comprising a water container body 2 and the cover 1, the cover 1 and the water container body 2 being fastened and assembled together in a detachable manner.

Embodiment 2

[0040] Different from the cover in Embodiment 1, as shown in FIG. 11, the reset elastic member in this embodiment is an elastic material component 162, specifically an elastic rubber ring, that is, one end of the elastic material component 162 is connected to the bracket 13 directly or indirectly, and the other end of the elastic material component 162 is connected to the pressing ring 14.

[0041] This embodiment also provides a water container, specifically comprising a water container body 2 and the cover 1, the cover 1 and the water container body 2 being fastened and assembled together in a detachable manner.
