The utility model discloses a cup, which comprises a cup body 1 and a cup cover 2.

In this embodiment, the cup body 1 may have a double-layer insulation structure or a single-layer structure. It should be noted that the cup body 1 with the double-layer heat insulation structure is the same as the prior art, and the description is omitted here.

In this embodiment, the cup body 1 has a cavity 11 and a cup opening 12, the cavity 11 is used as a main space for containing liquid, and the liquid can be poured out from the cavity 11 through the cup opening 12. The cup cover 2 covers the cup opening 12. In the present embodiment, the cup mouth 12 is closed by the structure of the cup lid 2.

The inner wall 13 of the cup opening is provided with an annular bayonet 14 which is arranged in a continuous annular shape on the inner wall 13 of the cup opening. By adopting the structure, the cup cover 2 can be inserted in any angle position relative to the cup body 1 in the circumferential direction, so that the cup cover 2 can be conveniently buckled into the cup mouth 12.

As shown in FIG. 3, the cup lid 2 includes a plug portion 21, in this embodiment, the plug portion 21 is used for being inserted into the cup opening 12, the outer portion of the plug portion 21 is substantially cylindrical, and the outer diameter of the plug portion 21 is slightly smaller than the inner diameter of the cup opening 12. The plug portion 21 is provided with a cavity 22, and the pressing head 3 for pressing operation is provided in the cavity 22. As shown in the figure, the top of the cavity 22 is an open opening, and after the pressing head 3 is placed in the cavity 22, the top of the pressing head 3 is exposed on the open opening, so that the pressing head 3 can be pressed. Usually, the cup lid 2 has an outer rim 31 on the outside of the plug 21, and the outer rim 31 is fitted on the outside of the cup opening 12. Through the structure that sets up outer fringe part 31, be convenient for handheld bowl cover 2.

The pressing head 3 is fixed with a plurality of jaws 4 laterally protruding from the surface of the pressing head 3. Usually, the number of the claws 4 is 2 or more, and the claws are uniformly distributed on the circumferential side of the pressing head 3. In the present embodiment, 8 claws 4 are provided. The outer end 41 of the claw is used for inserting the annular bayonet 14, the plug part 21 is provided with a channel 23, and the claw 4 passes through the channel 23 and is exposed out of the plug part 21. In the present embodiment, the jaws 4 are made of a plastic material, and the jaws 4 can be elastically deformed after being stressed.

The outer ends 41 of the jaws are always kept at the position extending into the annular bayonet 14, when the pressing head 3 is pressed downwards to make the pressing head 3 go downwards, the outer ends 41 of the jaws are supported on the channel 23 to cause the elastic deformation of the jaws 4 to make the outer ends 41 of the jaws exit the annular bayonet 14, and then the cup cover 2 can be taken down from the cup mouth 12. When the pressing head 3 is released from pressing downwards, the claws 4 are deformed again, so that the claws 4 extend out of the passages 23 and are inserted into the annular bayonets 14. It should be noted that, in a specific application, it is normal that the pressing head 3 is not pressed downward, so that the outer ends 41 of the claws are always kept at positions extending into the bayonets after the cup cover 2 is covered on the cup mouth 12.

It can be understood that, when the cup cover 2 is to be opened, the cup cover 2 and the cup opening 12 can be unlocked by pressing the pressing head 3 downwards, so that the cup cover 2 can be taken down from the cup body 1, and the operation can be completed by one hand, and the cup is simple and convenient to operate.

In the present embodiment, the jaw 4 has a portion 42 extending obliquely, as shown in the drawing, from a position where the jaw 4 is connected to the pressing head 3 to a position where an outer end 41 of the jaw extends obliquely with respect to the horizontal line, and the outer end 41 of the jaw is higher than a position where the jaw 4 is connected to the pressing head 3. The top of the outer end is a plane, and the top of the annular bayonet 14 is a plane, so that the top of the outer end is reliably contacted with the top of the annular bayonet 14, and when the plug part 21 bears the influence of air pressure in the cavity 11, the outer end 41 of the clamping jaw is prevented from being separated from the annular bayonet 14, so that the cup cover 2 and the cup body 1 are stably connected together. As shown in the drawings, the channels 23 are inclined with the outer ends of the channels 23 being higher than the inner ends of the channels 23, the outer ends of the channels being contacted by the outer ends 41 of the jaws. With this construction a large moment can be obtained which causes deformation of the jaws 4.

In this embodiment, the outer diameter of the plug portion 21 is slightly smaller than the inner diameter of the cup mouth 12, so that the exposed portions of the outer ends 41 of the jaws outside the channel 23 are relatively short, and therefore the outer ends 41 of the jaws have a greater bending resistance to ensure a secure connection between the lid 2 and the cup 1. In this embodiment, the distance from the plug 21 to the side wall 141 of the annular bayonet is smaller than the length of the jaw 4, so that the jaw 4 can be prevented from being deformed to a horizontal state with respect to the pressing head 3 when a large pressure is applied in the cavity 11. It will be appreciated that as the jaw 4 is deformed to the horizontal position, and the pressure in the cavity 11 is continuously increased, the jaw 4 will be further deformed to form the outer end 41 of the jaw lower than the position where the jaw 4 is connected to the pressing head 3, and this change in shape will result in the distance from the outer end 41 of the jaw to the pressing head 3 being reduced, so that the outer end 41 of the jaw is disengaged from the annular notch 14. That is, the distance from the plug portion 21 to the side wall 141 of the annular bayonet is smaller than the length of the claw 4, so that when a large pressure is applied to the cavity 11, the claw 4 can be effectively resisted from being excessively deformed, and the cup lid 2 and the cup body 1 can be firmly connected together.

As shown in the figure, the pressing head 3 is provided with a protruding edge 32 protruding laterally, and the plug 21 is provided with a stroke limiting groove 24 into which the protruding edge 32 is inserted. In a preferred embodiment, the stroke limiting groove 24 has an upper groove wall and a lower groove wall, which are abutted by the upward and downward convex edges 32, so that the stroke of the pressing head 3 is limited by the stroke limiting groove 24. As another structure, the stroke limiting groove 24 may not have a lower groove wall, and the bottom wall 221 of the cavity serves as a bottom dead center limit of the pressing head 3. In the present embodiment, the stroke of the pressing head 3 is limited by the structure of the stroke limiting groove 24, so that the pressing head 3 can be prevented from coming out of the cavity 22, and the jaws 4 can be prevented from being completely retracted into the passage 23.

In one embodiment, a compression spring (not shown) is further included, one end of the compression spring abuts against the pressing head 3, and the other end of the compression spring abuts against the inner wall of the cavity 22. Normally, the other end of the compression spring abuts against the bottom wall 221 of the cavity. Through the structure of the pressure spring, the jack catch 4 is favorable for being restored to an open state after elastic deformation.

In this embodiment, the plug portion 21 is in sealing engagement with the inner wall 13 of the rim of the cup by means of a sealing ring 51. Through the structure that sets up seal structure, improve the leakproofness of cup. Typically, the bottom of the cup 12 is provided with a constricted portion 15 for contact by the sealing ring 51. As shown in the drawing, the inner diameter of the throat portion 15 gradually increases from bottom to top. In a specific application, the sealing ring 51 can be tightly pressed on the necking part 15, and the sealing performance of the cup can be further improved by providing the necking part 15. The cup mouth 12 has a relatively large inner diameter at a position above the constricted portion 15, and may be in non-contact or light contact with the sealing ring 51. The cup cover 2 is convenient to disassemble and assemble. In the description of the present embodiment, the so-called light contact means that the plug portion 21 can be easily pulled out from the cup mouth 12. As another assembling structure of the gasket 51, a seal 52 for abutting the top of the cup mouth 12 is provided between the plug portion 21 and the outer rim portion 31.

The above embodiment is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited in this way, so: all equivalent changes made according to the structure, shape and principle of the utility model should be covered within the protection scope of the utility model.
