Description

Technical Field

[0001] The present invention relates to the technical field of liquid containers, and in particular to a cup cover and a cup. Background Art

[0002] In order to meet people's daily drinking water needs and take into account the convenience of drinking water, many manufacturers have integrated drinking straws into cup lids to make drinking water more convenient.

[0003] Currently, when drinking water, the straw needs to be exposed outside the cup for convenient drinking, but the straw needs to be able to be stored in the cup when not drinking water. Most existing cups have the straw in the shape of a hose and are provided with an openable flip cover. When the flip cover is closed, the drinking end of the straw is pressed and folded for storage. When the flip cover is opened, the straw is released for drinking water. However, after long-term use, the straw will be deformed or damaged due to repeated folding, which will shorten the service life of the straw. Moreover, the folded and stored straw often cannot be quickly and smoothly reset outward when the flip cover is opened. Sometimes, the straw needs to be manually moved to a larger angle for convenient drinking, which can easily cause the problem of straw contamination. Summary of the Invention

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] See also Figure 1-11 The present invention provides a cup cover, including a cover body 100 having a through hole 101 thereon; specifically, the through hole 101 can be opened at any position on the surface of the cover body 100, preferably in the center position, which can improve the aesthetics; specifically, the surface of the cover body 100 has a mounting groove 102, and the mounting groove 102 can be a closed groove structure or a semi-open groove structure with one end extending to the edge of the cover body 100 used in this application.

[0024] The tube body 200 passes through the through hole 101 and is slidably matched with the cover body 100 , and an elastic member 201 is sleeved on the tube body 200 ; specifically, the tube body 200 is made of a hard environmentally friendly material; specifically, the elastic member 201 can be a spring.

[0025] The plug 300 is used to seal the tube body 200; specifically, a sealing gasket is provided inside the plug 300 to ensure that when the cup lid is in the closed state, after the plug 300 is connected to the tube body 200, the end of the tube body 200 can be effectively sealed to prevent liquid leakage.

[0026] The unlocking member 400 is provided on the cover 100 ; specifically, it is installed in the installation groove 102 .

[0027] When the cup cover is in the initial state, the tube body 200 is in the open state, and the end portion is located outside the cover body 100; When the cup lid is in a closed state (since the cup lid is used together with the cup body 600 described later, the closed state here means that when the cup lid is connected to the cup body 600, the tube body 200 is also in a completely sealed state, and the liquid contained in it will not leak out), the end of the tube body 200 is sealed by the plug 300 and is located in the lid body 100, and the plug 300 is locked by the unlocking member 400; When the cup lid is in the open state (since the cup lid is used together with the cup body 600 described later, the open state here refers to the tube body 200 being in the pop-up open state, that is, in the drinkable state, rather than the separation of the cup lid and the cup body 600), the unlocking member 400 releases the locking plug 300, and the elastic member 201 restores the tube body 200 to its initial state.

[0028] In this embodiment, when the cup lid is in a closed state, the plug 300 is pressed against one end of the tube body 200, and the plug 300 is located inside the cover body 100. At this time, the unlocking member 400 locks the plug 300, so that the cover body 100 is in a sealed state as a whole. When drinking water is needed, the unlocking member 400 is operated to release the lock of the plug 300. At this time, the elastic member 201 recovers its deformation and applies an outward force to the tube body 200, so that the tube body 200 moves as a whole and partially extends out of the cover body 100. When the tube body 200 moves outward, the plug 300 will also be separated from the tube body 200 under the action of the impact force, so that the part of the tube body 200 that contacts the mouth is directly exposed.

[0029] The present invention arranges the tube body 200 to slide with the cover body 100 and cooperates with the use of the elastic member 201. When drinking water, the unlocking member 400 is toggled to make the tube body 200 move outward as a whole for a distance, thereby avoiding damage to the tube body 200 and improving the service life. In addition, through the cooperation between the plug 300 and the unlocking member 400, the plug 300 has the functions of sealing the tube body 200 and locking the tube body 200 at the same time, which has a compact structure and reduces costs.

[0030] In one embodiment, the cover 100 is provided with a vent hole 104 , and the unlocking member 400 is pressed against the vent hole 104 . When the cup cover changes from a closed state to an open state, the vent hole 104 is opened as the unlocking member 400 moves.

[0031] This embodiment is configured such that when the cup lid is in a closed state, the unlocking member 400 presses on the vent 104, and the vent 104 is in a closed state. When the tube body 200 is unlocked, the unlocking member 400 is controlled to move. As the unlocking member 400 moves, the vent 104 is opened. At this time, the air inside and outside the cup body 600 is connected, achieving a pressure relief effect, avoiding the problem of excessively high liquid temperature in the cup body 600 and the difference in air pressure inside and outside the cup body 600, which may cause splashing outwards, thereby improving safety.

[0032] In one embodiment, a hollow tube 103 connected to the cover body 100 is further included, and a ventilation groove 1031 is provided on the inner surface of the hollow tube 103. When the cup cover changes from a closed state to an open state, the ventilation groove 1031 is opened as the tube body 200 moves, and remains open before the cup cover changes to a closed state.

[0033] Specifically, one end of the vent groove 1031 extends to the end of the hollow tube 103, and the other end is located inside the hollow tube 103; specifically, a plurality of vent grooves 1031 can be provided on the inner surface of the hollow tube 103; This embodiment is configured such that, by placing the tube body 200 in the channel and slidingly cooperating with the hollow tube 103, it can provide guidance for the tube body 200 during the unlocking and locking movement, making the movement of the tube body 200 more stable, thereby improving the service life of the cup cover.

[0034] In order to avoid the problem of sucking difficulty and difficulty in drinking water effectively when drinking water, a ventilation groove 1031 is provided. When the tube body 200 is unlocked, as the tube body 200 moves, the sealing ring 202 will be driven to move to the ventilation groove 1031. Since the ventilation groove 1031 is opened on the inner surface of the hollow tube 103, when the sealing ring 202 moves to the ventilation groove 1031, there will be a gap between the outer wall of the sealing ring 202 and the inner surface of the hollow tube 103. At this time, the space inside the cup 600 is connected with the external space, achieving the effect of balancing the internal and external air pressure, making drinking water smoother and there will be no problem of drinking water resistance.

[0035] It should be noted that, in this embodiment, the tube body 200 is slidably fitted with the hollow tube 103, and the elastic member 201 is correspondingly arranged in the hollow tube 103. If the hollow tube is not provided, the elastic member 201 can be connected to the cover body 100 at one end and to the tube body 200 at the other end, and the function of the tube body 200 popping out can also be realized.

[0036] Preferably, a sealing ring 202 having a diameter the same as the inner diameter of the hollow tube 103 is provided on the outer surface of the tube body 200 .

[0037] Specifically, the sealing ring 202 can be a rubber ring or a silicone ring that is installed later, or can be directly integrally formed with the hollow tube 103 .

[0038] This embodiment is configured such that the sealing effect between the tube body 200 and the hollow column 103 can be improved by configuring the sealing ring 202. In addition to the sealing provided by the plug 300, a further sealing function is provided to ensure that the liquid does not leak out through the tube body 200.

[0039] In one embodiment, a pressing member 500 is further included, which cooperates with the cover body 100 to limit the unlocking member 400. The pressing member 500 has a first card slot 501 and a second card slot 502, wherein a first boss 1021 that cooperates with the first card slot 501 is provided in the installation slot 102, and a second boss 402 that cooperates with the second card slot 502 is provided on the unlocking member 400.

[0040] This embodiment is configured such that the pressing member 500 is tightly connected to the cover body 100 through the first slot 501 and the first boss 1021, and the pressing member 500 stably installs the unlocking member 400 on the cover body 100 through the second slot 502 and the second boss 402, making the unlocking member 400 more stable during movement.

[0041] In one embodiment, the plug 300 is softly connected to the lid 100 or the pressing member 500, and the plug 300 automatically separates from the tube 200 when the cup lid changes from a closed state to an open state. Specifically, the inner diameter of the plug 300 is larger than the outer diameter of the tube 200.

[0042] This embodiment is configured such that, during the unlocking process of the tube body 200, as the elastic member 201 applies an outward force to the tube body 200, the plug 300 can automatically detach from the tube body 200 under this force, and the plug 300 does not need to be removed manually, and drinking water can be directly performed, thereby improving convenience.

[0043] In one embodiment, the unlocking member 400 is automatically reset by the restoring member 401 after releasing the locking plug 300 .

[0044] Specifically, the reset member 401 may be a spring.

[0045] This embodiment is configured such that, through the configuration of the reset member 401, after the unlocking member 400 is pushed to complete the unlocking of the tube body 200, the unlocking member 400 is released, driving the unlocking member 400 to automatically reset, thereby facilitating efficient reuse. The difficulty of operation is reduced, and it is only necessary to operate the unlocking member 400 during the unlocking process. During the locking process, it is only necessary to press the tube body 200 through the plug 300, first making the plug 300 press against the unlocking member 400, and then applying a greater force so that the plug 300 pushes the unlocking member 400 to move until the unlocking member 400 and the plug 300 form a locking fit, thereby completing the locking.

[0046] It should be noted that, since the present application adopts a technical solution of automatic reset of the unlocking member 400, it is necessary to set up a vent hole 104 and a vent groove 1031. If the unlocking member 400 needs to be manually reset after unlocking, that is, the vent hole 104 is always in an open state, then there is no need to set up the vent groove 1031. The two implementation methods can be used in parallel or superimposed, and both fall within the scope of protection of the present application.

[0047] In one embodiment, the plug 300 has a limiting groove 301 that cooperates with the unlocking member 400 .

[0048] In one embodiment, the unlocking member 400 includes a sliding portion 4001 and a locking portion 4002 , and the locking portion 4002 can move relative to the sliding portion 4001 under the action of an external force; Preferably, two locking parts 4002 can be provided and are symmetrically distributed relative to the sliding part 4001.

[0049] In one embodiment, the locking portion 4002 has an arcuate surface 4002a that contacts the end surface of the plug 300 during the locking process and a sliding surface 4002b that contacts the limiting groove 301 during the unlocking process.

[0050] This embodiment is configured such that the arcuate surface 4002a is configured so that during the locking process, after the plug 300 contacts the locking portion 4002, a force is applied to break through the obstruction of the locking portion 4002, and when the limiting groove 301 passes, the locking portion 4002 is reset and snapped into the limiting groove 301, completing the locking; the sliding surface 4002b is configured so that during the unlocking process, the unlocking member 400 is pushed to move, and the sliding surface 4002b slides along the limiting groove 301 until it is completely disengaged from the limiting groove 301, thereby releasing the lock on the tube body 200 and completing the unlocking, and the locking portion 4002 will be reset in time after being completely disengaged from the limiting groove 301, so that the locking can be repeated subsequently.

[0051] In one embodiment, the sliding portion 4001 and the locking portion 4002 are integrally formed or movably connected via a connecting piece.

[0052] Specifically, when the integral molding is set up, the locking part 4002 is elastically connected to the sliding part 4001, and when the plug 300 contacts the locking part 4002, the locking part 4002 opens to the side through the weak position thereon under the push of the plug 300, and is locked into the limiting groove 301 when it passes through.

[0053] Specifically, the connecting member may be a combination of a pin and a torsion spring.

[0054] This embodiment is configured so that during the cup lid locking process, as the plug 300 presses the tube body 200 to move and contacts the locking portion 4002, a greater force is applied to allow the plug 300 to break through the obstruction of the locking portion 4002. When the limiting groove 301 passes the locking portion 4002, the locking portion 4002 loses the external force and resets, and then is stuck in the limiting groove 301 to achieve locking.

[0055] The present invention also provides a cup, please refer to Figure 12 , including the cup cover and the cup body 600 as described above.

[0056] Specifically, the cup cover is threadedly connected to the cup body 600 .

[0057] In one embodiment, a water pipe 601 connected to the tube body 200 is provided in the cup body 600 .

[0058] Specifically, the water pipe 601 can be a hose or a hard pipe. If a hose is used, a suitable length needs to be retained in the cup body 600 so that after the tube body 200 is unlocked, the water pipe 601 can still contact the bottom of the cup body 600; if a hard pipe is used, the tube body 200 is slidably connected to the water pipe 601, and a bracket for fixing the water pipe 601 is provided in the cup body 600.

[0059] It should be noted that if the embodiments of the present invention involve directional indications such as up, down, left, right, front, back, etc., then the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture as shown in the accompanying drawings. If the specific posture changes, the directional indication will also change accordingly.

[0060] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features.
