Description

Technical Field

[0001] The utility model relates to the technical field of heat preservation containers, in particular to a safety cup cover and a beverage container. Background Art

[0002] Thermos cup is a common container in daily life. The cup body is generally a water container made of ceramic or stainless steel with a vacuum layer. There is a cup lid on the top and it is tightly sealed. The vacuum insulation layer can delay the heat dissipation of the water and other liquids inside to achieve the purpose of heat preservation. Due to its heat preservation effect, when it is used to hold hot or cold drinks, it can effectively delay the temperature change of hot or cold drinks. It is easy to carry and easy to use, and can meet people's different usage needs.

[0003] In order to make the cup lid open quickly and conveniently, the prior art generally uses a one-touch lid design. However, during the use of the thermos cup, it is found that the cup lid is often opened by mistake, causing leakage of the internal liquid, especially when it is filled with hot drinks, which can easily cause burns. To solve this technical problem, a thermos cup lid structure with a safety lock has appeared on the market. In the Chinese patent document with the announcement number CN204541575U and the invention name of the new bounce cup lid, a new bounce cup lid is disclosed, which adds a lock to the base and provides an outward protrusion on the upper cover. After the upper cover is closed, the lock is turned up and buckled on the protrusion. At this time, the upper cover cannot bounce up even if the button is pressed. When drinking water, before pressing the button to open the lid, the lock must be turned down and unlocked before the upper cover can be smoothly popped up.

[0004] Although the above cup cover structure increases the safety of the cup cover to a certain extent, it is inconvenient to open the cup cover when the cup cover needs to be operated with one hand. For example, when a driver uses a thermos cup with such a cup cover to hold a drink while driving, he needs to open the lock first and then press the unlock button to open the cup cover to drink the drink, which is inconvenient for the driver and poses a great safety hazard.

[0005] Therefore, the cup cover structure needs to be further improved to reduce the probability of accidental opening of the cup cover switch while improving the convenience of opening the cover. Utility Model Content

[0032] The edge of the top cover 1, 1' is provided with hooks 11, 1'1 towards the bottom cover 3, a driving connecting rod 6 is provided inside the bottom cover 3, buttons 2 corresponding to the driving connecting rod 6 are symmetrically provided on both sides of the bottom cover 3, and a buckle 61 corresponding to the hooks 11, 1'1 is provided at one end of the driving connecting rod 6. When the top cover 1, 1' is connected to the bottom cover 3, the buckle 61 can be pressed onto the hooks 11, 1'1, thereby limiting the hooks 11, 1'1 and preventing the top cover 1, 1' from rotating in a direction away from the bottom cover 3 to open the cup cover, so as to maintain the sealing of the cup cover.

[0033] like Figure 3-4As shown, the two sides of the buckle 61 of the driving connecting rod 6 are respectively provided with a first driving groove 62 and a second driving groove 63. Preferably, the first driving groove 62 and the second driving groove 63 are symmetrically arranged, and the first driving groove 62 is integrally connected with a first elastic arm 64 and a first fulcrum 641 on the same side, and the second driving groove 63 is integrally connected with a second elastic arm 65 and a second fulcrum 651 on the same side; the bottom cover 3 is provided with a first button 21 corresponding to the first driving groove 62 and a second button 22 corresponding to the second driving groove 63, and the first button 21 is provided with a first driving block 211 facing the first driving groove 62, and the first driving block 211 abuts against the inclined surface of the first driving groove 62, and the pressing When the first button 21 is pressed, the first driving groove 62 is affected by the force component of the first driving block 211, and is horizontally displaced away from the buckle 61, compressing the first elastic arm 64. The first elastic arm 64 is elastically deformed with the first fulcrum 641 as the force fulcrum, that is, the first elastic arm 64 is compressed, deformed or rebounded with the first fulcrum 641 as the force fulcrum. The horizontal displacement of the first driving groove 62 can only drive the buckle 61 to partially displace relative to the hook 11, 1'1, and cannot completely separate the buckle 61 from the hook 11, 1'1, so that the buckle 61 can only partially detach from the hook 11, 1'1, and cannot release the limit of the buckle 61 on the hook 11, 1'1. Therefore, in the case of a single When the first button 21 is pressed alone, the top cover 1, 1' cannot be opened; when the force restriction of the first button 21 is removed, the first driving groove 62 is reset under the rebound action of the first elastic arm 64, and the first button 21 is reset under the action of the first driving groove 62; the second button 22 is provided with a second driving block 221 facing the second driving groove 63, and the second driving block 221 is in inclined contact with the second driving groove 63. When the second button 22 is pressed, the second driving groove 63 is affected by the force component of the second driving block 221, and is horizontally displaced away from the buckle 61, compressing the second elastic arm 65, and the second elastic arm 65 is elastically deformed with the second fulcrum 651 as the force fulcrum. shape, that is, the second elastic arm 65 is compressed and deformed or rebounded with the second fulcrum 651 as the force fulcrum, and the horizontal displacement of the second driving groove 63 can only drive the buckle 61 to partially displace relative to the hook 11, 1'1, and cannot separate the buckle 61 from the hook 11, 1'1, so that the buckle 61 can only partially disengage from the hook 11, 1'1, and cannot release the limit of the buckle 61 on the hook 11, 1'1. Therefore, when the second button 22 is pressed alone, the top cover 1, 1' cannot be opened. When the external force restriction of the second button 22 is removed, the second driving groove 63 is reset under the rebound force of the second elastic arm 65, and the second button 22 is also reset under the force of the second driving groove 63;By pressing the first button 21 and the second button 22 at the same time, the driving link 6 can drive the first driving slot 62 and the second driving slot 63 to move away from the buckle 61 under the simultaneous action of the first driving block 211 and the second driving block 221, and the first elastic arm 64 and the second elastic arm 65 elastically deform to drive the buckle 61 to disengage from the hook 11, 1'1, and release the limit of the hook 11, 1'1, so that the top cover 1, 1' can be opened. Preferably, the driving link 6 is an integrated molding setting, which effectively reduces the number of components of the safety cup cover and is conducive to improving the assembly efficiency of the safety cup cover. ;

[0034] In an exemplary example, the first driving block 211 is slidably connected to the first driving slot 62, and the second driving block 221 is slidably connected to the second driving slot 63, and the movement directions of the first driving block 211 and the second driving block 221 are perpendicular to the movement directions of the first driving slot 62 and the second driving slot 63.

[0035] In one embodiment, a torsion spring 7 is provided between the top cover 1, 1' and the bottom cover 3. When the first button 21 and the second button 22 are pressed simultaneously to disengage the buckle 61 from the hook 11, 1'1, the top cover 1, 1' can be bounced open relative to the bottom cover 3 under the action of the torsion spring 7, thereby opening the water outlet channel 4.

[0036] like Figure 3-8 As shown, the second embodiment of the utility model relates to a safety cup cover. The second embodiment is substantially the same as the first embodiment, with the main difference being that in the second embodiment, a pressure relief valve 8 is further provided on the top cover 1'. The pressure relief valve 8 can effectively release the air pressure in the beverage container. As is known to all, when the air pressure in the container is too high, the top cover 1' is opened, and the high-pressure gas and liquid in the beverage container will be rapidly discharged from the water outlet channel 4, which may cause harm to the human body.

[0037] The top cover 1' is provided with a pressure relief valve 8, and the pressure relief valve 8 includes a valve cavity 84 arranged toward the bottom cover 3, and a valve stem 81 penetrated in the valve cavity 84, a cavity bottom 85 of the valve cavity 84 is provided with a through hole, one end of the valve stem 81 is arranged through the cavity bottom 85, and the end of the valve stem 81 facing the bottom cover 3 is provided with a valve head 83 for sealing the through hole, and an elastic component 82 is provided between the end of the valve stem 81 away from the bottom cover 3 and the cavity bottom 85.

[0038] The pressure relief valve 8 includes a valve cavity 84 arranged at the center of the top cover 1' and arranged toward the bottom cover 3, the valve cavity 84 is arranged corresponding to the water outlet channel 4, a valve stem 81 is arranged in the valve cavity 84, a cavity bottom 85 of the valve cavity 84 is provided with a through hole, one end of the valve stem 81 passes through the through hole and is arranged toward the water outlet channel 4, and a valve head 83 is arranged at the end facing the water outlet channel 4; an elastic component 82 is arranged between the end of the valve stem 81 away from the water outlet channel 4 and the cavity bottom 85, when the valve stem 81 is not subjected to external force, under the action of the elastic component 82, the valve head 83 abuts against the cavity bottom 85 to seal the through hole, so as to block the communication between the valve cavity 84 and the water outlet channel 4; when the valve stem 81 is pressed toward the bottom cover 3, the valve head 83 is separated from the cavity bottom 85, and the valve cavity 84 is connected with the water outlet channel 4 through the through hole of the cavity bottom 85, so as to safely release the air pressure in the beverage container.

[0039] For example, when a beverage container contains high-temperature liquid or carbonated beverage, the beverage container is likely to generate a higher air pressure than the external air pressure. Before opening the top cover 1', the valve stem 81 can be pressed to slowly release the air pressure in the beverage container to prevent the high-pressure gas and / or liquid in the beverage container from being rapidly discharged from the water outlet channel 4 when the top cover 1' is opened, thereby preventing harm to the human body.

[0040] The third embodiment of the utility model relates to a beverage container, which comprises a container body (not shown in the drawings) having an open end, and a safety cup cover as described above arranged at the open end.

[0041] Compared with the prior art, the safety cup cover and beverage container provided by the utility model have a setting in which the buckle and the hook can be disengaged only by the linkage of the first button and the second button, thereby reducing the probability of the top cover opening due to the cup cover accidentally touching the button, and can effectively reduce the risk of liquid leakage in the beverage container. At the same time, when holding the container body, the first button and the second button can be pressed by the thumb and other fingers at the same time, thereby improving the convenience of opening the cup cover. On the other hand, through the setting of the pressure relief valve on the top cover, the air pressure in the beverage container can be safely released, thereby reducing the risk of using the beverage container.

[0042] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present invention, and in actual applications, various changes may be made thereto in form and detail without departing from the spirit and scope of the present invention.
