Description

Technical Field

[0001] The present invention belongs to the technical field of water cups, and particularly relates to a double - lid straw cup. Background Art

[0002] Existing dual - purpose cups can be used to drink water through a nozzle or a direct - drinking opening to meet different usage needs of users. The applicant has applied for a double - lid dual - purpose cup (Patent No.: 2024206635801). When using this water cup, pressing the switch button once opens the outer flip - lid, exposing the nozzle, and the user can drink water through the nozzle; pressing the switch button again opens the inner flip - lid, exposing the direct - drinking opening, and the user can drink water through the direct - drinking opening. In other words, if the user wants to drink water through the direct - drinking opening, pressing the lid - opening button once cannot open both the outer flip - lid and the inner flip - lid simultaneously, and it needs to be pressed twice.

[0003] Therefore, it is necessary to make improvements. Summary of the Invention

[0004] The purpose of the present invention is to provide a double - lid straw cup that can open the outer lid or simultaneously open the outer lid and the inner lid by pressing a button once.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is:

[0006] A double - lid straw cup includes a cup body and a cup lid. The cup lid includes a cup - lid body, an inner lid, an outer lid, a convection member, and a nozzle. The first side of the cup - lid body is rotatably connected to the inner lid, and the second side of the cup - lid body is engaged with or separated from the inner lid. The first side of the cup - lid body is rotatably connected to the outer lid, and the second side of the cup - lid body is engaged with or separated from the outer lid. The cup - lid body is provided with a first water outlet and a second water outlet. The inner lid is provided with a first mounting hole and a second mounting hole. The convection member is inserted through the first mounting hole, and the nozzle is inserted through the second mounting hole. The convection member is provided with a convection hole, and the nozzle has a sucking channel. When the inner lid is engaged with the cup - lid body, the lower end of the convection member abuts against the orifice edge of the first water outlet, the convection hole corresponds to and is in communication with the first water outlet, the lower end of the nozzle abuts against the orifice edge of the second water outlet, and the sucking channel corresponds to and is in communication with the second water outlet. The nozzle is inclined towards the convection - member side. When the outer lid is engaged with the cup - lid body, the nozzle is pressed between the inner bottom wall of the outer lid and the outer top wall of the inner lid, thereby closing the sucking channel of the nozzle, and the side surface of the nozzle blocks the convection hole. It is characterized in that,

[0007] The engaging end of the outer lid is provided with a second snap - ring. The engaging end of the inner lid extends downward to form an elastic member. The top end of the elastic member is connected to the inner lid. A card slot is provided in the middle of the elastic member, and a first snap - ring is provided at the bottom end of the elastic member. The outer lid is also provided with a buckle for engaging with the card slot.

[0008] The cup cover body is provided with an opening button. A compression spring is arranged between the opening button and the cup cover body. The opening button is provided with a first slot and a second slot. The rear side wall of the first slot is provided with a first hook, and the first hook can be buckled with a first snap ring to keep the inner flip cover in a buckled state. The rear side wall and the front side wall of the second slot are respectively provided with a second hook and a third hook. The third hook is located above the second hook. The second hook can be buckled with a second snap ring to keep the outer cover in a buckled state. The third hook can be buckled with the second snap ring to keep the outer cover in a semi-open state.

[0009] The cup cover body is further provided with a locking member which has a locking tongue. A chute extending circumferentially is formed on the cup cover body. The locking member is embedded in the chute. The switch button is further provided with a notch for the locking tongue to extend into. The notch is communicated with the first slot. The locking member can move in the chute so that the locking tongue can move between a locking position and an unlocking position.

[0010] When the locking tongue is in the locking position, pressing the opening button can push the locking tongue and the elastic member to move backward together. The clamping groove on the inner cover is disengaged from the buckle on the outer cover. Since the locking tongue abuts against the first snap ring of the elastic member, the inner cover cannot be opened. When the locking tongue is in the unlocking position, the positions of the locking tongue and the elastic member are staggered, so that the inner cover can be opened.

[0011] The beneficial effects of the double-cover straw cup provided by the present invention are as follows: Compared with the prior art, firstly, an elastic member is provided at the buckling end of the inner cover. The elastic member is provided with a clamping groove and a first snap ring. The inner cover can be buckled with the buckle of the outer cover through its clamping groove. Secondly, a locking member is added to the cup cover body. When the locking member is in the locking position, pressing the opening button will squeeze the locking member and the elastic member. When squeezing the elastic member, the clamping groove of the inner cover is disengaged from the buckle of the outer cover, so that the outer cover is not restricted by the inner cover, and the locking member squeezes the first snap ring on the elastic member to prevent the inner cover from being opened. When the locking member is in the unlocking position, the inner cover can be opened. Pressing the switch button, since the inner cover is buckled with the buckle of the outer cover through its clamping groove, the inner cover and the outer cover are opened simultaneously. That is, when the user wants to drink water through the nozzle, the locking member is toggled to the locking position. At this time, pressing the opening button, only the outer cover is opened to expose the nozzle. When the user wants to drink water through the direct drinking port, the locking member is toggled to the unlocking position. At this time, pressing the opening button, the outer cover and the inner cover are opened simultaneously to expose the direct drinking port. By adding the structure of the locking member and the elastic member, the present invention realizes that pressing the opening button once can open the outer cover or open the outer cover and the inner cover simultaneously.

[0012] In one embodiment, the cup cover body includes a first body and a second body. A chute is provided on the outer peripheral side of the first body. The second body is provided with a window corresponding to the position of the chute. The second body is sleeved outside the first body. The locking member is further provided with a dial block. The locking member is installed in the chute, and the dial block is located at the window. Applying force to the dial block can make the locking member slide.

[0013] In one embodiment, an anti-fooling pattern is provided near the window on the second body. The anti-fooling pattern is used to indicate that the dial block is on the left side of the window, that is, the suction nozzle mode is in effect when the locking member is in the locked position; when the dial block is on the right side of the window, that is, the direct drinking mode is in effect when the locking member is in the unlocked position.

[0014] In one embodiment, the locking tongue of the locking member is made of an elastic material. BRIEF DESCRIPTION OF THE DRAWINGS

Exhaust steam in the semi-open state to prevent hot water steam from scalding the human body. Release the open lid button 7, and under the elastic restoring force of the compression spring, the open lid button 7 moves forward, the third hook 73 disengages from the second snap ring 32, and under the elastic force of the straw 5, the flip-up cover 3 opens upward (as Figure 15 , 16 shown). Since the outer cover 3 and the inner cover 2 are always buckled together by the buckle 31 and the card slot 210, the outer cover 3 and the inner cover 2 are opened together.

[0056] When the user wants to drink water in the sipping mode, toggle the locking member 103 to make the locking member 103 in the locking position. Press the open lid button and only the outer cover is opened (as Figure 10 shown), exposing the sipping nozzle. In the sipping mode, the convection member plays a convection role to make drinking smooth. When the user wants to drink water in the direct drinking mode, toggle the locking member 103 to make the locking member in the unlocking position. At this time, press the open lid button 7, and the outer cover 3 and the inner cover 2 are opened simultaneously, exposing the direct drinking port. In the direct drinking mode, the first water outlet 101 serves as the water outlet, and the second water outlet 102 plays a convection role to make drinking smooth.

[0057] Compared with the prior art, the double-lid straw cup provided by the present invention has the following features: First, an elastic member 21 is provided at the fastening end of the inner lid 2. A card slot 210 and a first snap ring 211 are provided on the elastic member 21. The inner lid 2 can be fastened to the buckle 31 of the outer lid 3 through its card slot 210. Second, a locking member 103 is added to the cup lid body 1. When the locking member 103 is in the locked position, pressing the open lid button 7 will squeeze the locking member 103 and the elastic member 21. When squeezing the elastic member 21, the card slot 210 of the inner lid 2 is disengaged from the buckle 31 of the outer lid 3, so that the outer lid 3 is not restricted by the inner lid 2, and the locking member 103 squeezes the first snap ring 211 on the elastic member 21 to prevent the inner lid 2 from being opened. When the locking member 103 is in the unlocked position, the inner lid 2 can be opened. Pressing the switch button 7, since the inner lid 2 is fastened to the buckle 31 of the outer lid 3 through its card slot 310, the inner lid 2 and the outer lid 3 are opened simultaneously. That is, when the user wants to drink water through the straw, the locking member 103 is toggled to the locked position. At this time, pressing the open lid button 7 will only open the outer lid 3, exposing the straw. When the user wants to drink water through the direct drinking port, the locking member 103 is toggled to the unlocked position. At this time, pressing the open lid button 7 will open the outer lid 3 and the inner lid 2 simultaneously, exposing the direct drinking port. By adding the structure of the locking member 103 and the elastic member 21, the present invention realizes that pressing the open lid button once can open the outer lid or open the outer lid and the inner lid simultaneously.

[0058] In one embodiment, the elastic member 21 is made of an elastic material such as PP (polypropylene) or PCT (polyvinyl chloride). Since PP and PCT have elasticity, the locking member 103 can squeeze the elastic member 21 to disengage the card slot 210 of the inner lid 2 from the buckle 31 of the outer lid 3.

[0059] In one embodiment, referring to Figure 2 and Figure 6 , the cup lid body 1 is further provided with a straw 8. The upper end of the straw 8 is communicated with the second water outlet 102, and the lower end of the straw 8 extends to the inner bottom of the cup body 4.

[0060] In one embodiment, referring to Figure 16 , the cup lid body 1 is further provided with an annular direct drinking water guiding member 11. The direct drinking water guiding member 11 is wound around the outer peripheral sides of the first water outlet 101 and the second water outlet 102 to guide the water flow when drinking.

[0061] In one embodiment, referring to Figure 2, the cup lid body 1 includes a first body 104 and a second body 105. A sliding groove 1040 is provided on the outer peripheral side of the first body 104. The second body 105 is provided with a window 1050, and the window 1050 corresponds to the position of the sliding groove 1040. The second body 105 is sleeved outside the first body 104. The locking member 103 is further provided with a dial block 1032. The locking member 103 is installed in the sliding groove 1040, and the dial block 1032 is located at the window 1050. Applying force to the dial block 1032 can make the locking member 103 slide.

[0062] In one embodiment, refer to Figure 16 , a foolproof pattern 1060 is provided on the second body 105 near the window 1050. The foolproof pattern 1060 is used to indicate that it is the suction nozzle mode when the dial block 1032 is located on the left side of the window (i.e., the locking member is in the locked position); it is the direct drinking mode when the dial block 1032 is located on the right side of the window (i.e., the locking member is in the unlocked position).

[0063] In one embodiment, the locking tongue 1031 of the locking member 103 is made of an elastic material. When both the outer lid 3 and the inner lid 2 are opened and the locking member 103 is in the locked position (the dial block 1032 is located on the left side of the window), when the inner lid 2 is covered, the first snap ring 211 of the inner lid 2 touches the locking tongue 1031 of the locking member 103 and presses down the locking tongue 1031. After the inner lid 2 is snapped in place, the locking tongue 1031 of the locking member 103 rebounds upward, and the locking tongue 1031 abuts against the first snap ring 211 of the elastic member 21. This can avoid the situation where the inner lid 2 cannot be snapped in when the locking member 103 is in the locked position.

[0064] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
