TW202007605A - Lid assembly for cup - Google Patents

Abstract

A lid assembly generally includes a shell body, a sealing member, and a nut. The shell body has a top portion and a circumferential portion. The shell body defines a water outlet and an air vent at an annular top surface thereof, and defines a through hole at a recessed surface thereof. The circumferential portion is provided at its outer surface with upper and lower flanges and connection means. The sealing member has a connection wing and a central shaft. The connection wing is provided with two pads capable of sealing the water outlet and the air vent, respectively. In use, the sealing member can be rotated forwardly to seal the water outlet and the air vent, thereby closing a cup fitted with the assembly. When drinking the beverage contained in the cup, the sealing member can be rotated reversely to uncover the water outlet and the air vent.

Description

Cup lid

The invention relates to a cup cover, in particular to a type that can prevent liquid leakage in the cup body and is more convenient to use.

Press, in order to prevent the leakage of the liquid contained in the cup body, and it is convenient for the cup body to carry around, most of the cups are provided with a cup cover, and the general combination of the cup cover and the cup body is screw thread. The cup lid is screwed on the cup body. When you want to drink boiled water, you must unscrew the cup lid and screw the cup lid tightly after drinking to prevent the liquid in the cup from seeping out. This screw lock cup The capping method cannot be used with one-handed operation, and the cap is easily lost after it is removed from the cup body, which can easily lead to the situation where the cap cannot be found when it is intended to be used. Therefore, it is extremely inconvenient in use; A cup lid with a flip lid is pivotally connected to the body, a torsion spring is provided at the pivotal connection between the flip lid and the lid body, and a buckle switch is provided at the opposite side of the pivot joint to screw the lid body onto the cup body first , And use the snap switch to set the flip cover buckle on the cover body. When drinking water, the user only needs to press the snap switch with one hand to open the flip cover by the elastic force of the torsion spring. At this time, press the lid back onto the lid body and buckle it. However, although this kind of cup lid with a lid can be operated with one hand, it is more convenient to use, but its snap switch is easy to be mistaken If the cover is opened by mistake, the liquid in the cup leaks out, and the bags and items are wetted, which is still not ideal in use.

The main purpose of the present invention is to provide a cup lid, which can effectively solve the shortcomings of the conventional cup lid when it is used.

The cup cover of the present invention includes: a cover body, a concave surface is provided in the center of the top surface of the cover body, a perforation is provided in the concave surface, an arc-shaped limiting groove is provided on the wall surface of the perforation, and the top surface of the cover body One edge is provided with a water outlet, the top surface of the cover body is provided with an air hole on the edge of the water outlet, the cover body is provided with a ring groove on the outer wall surface, and a snap flange is provided above the ring groove. The bottom surface of the buckle flange is provided with a positioning convex body corresponding to the position of the water outlet and the air hole, a positioning baffle is provided below the ring groove, and a group for assembling with the cup body is provided at the bottom of the cover body The connecting part; a sealing spiral body, which is set on the upper part of the cover body, the middle part of the sealing spiral body corresponding to the concave surface of the cover body is set as a concave arc surface, and each side of the sealing spiral body extends downward A buckle part, a buckle flange is provided on the inner surface of the buckle part, a locating slot is provided on the buckle flange, and the bottom surface of the sealing rotator is provided with a water outlet corresponding to the water outlet of the cover body An anti-relief pad is provided with an air vent anti-relief pad corresponding to the position of the air hole of the cover body. A connecting rod is provided in the middle of the bottom of the sealing rotating body. The connecting rod penetrates into the perforation of the cover body. A leak-proof washer is provided. The lower part of the connecting rod is provided with an externally threaded section. The externally threaded section protrudes from the bottom of the cover body. The connecting rod is provided with a limit stop body. The limit stop system is provided on In the limiting groove of the cover body; a nut is screwed on the external thread section of the connecting rod of the sealing rotary body, and the nut is provided with an internal thread for screwing with the external thread section.

The cup cover of the present invention, wherein the snap flange provided above the ring groove of the cover body is set to an oval shape, and the snap flange corresponds to the portion between the water outlet and the air hole relative to the ring groove The depth is set to be deeper, and the depth between the snap flange perpendicular to the opposite part of the water outlet and the air hole to the ring groove is set to be shallower.

According to the cup cover of the present invention, the buckle flange provided above the ring groove of the cover body is set to be thicker corresponding to the opposite portion of the water outlet and the air hole, and the buckle flange is perpendicular to the The thickness of the opposite part of the water outlet and the air hole is set to be thin, so that the buckle flange is gradually tapered from thick to thin, and when the sealing rotary body is rotated to the sealing position, the sealing rotary body follows The buckle flange can be slightly depressed under the change of the slope of thinning and thickening, and the water outlet relief pad and the air hole relief pad can completely close the water outlet and the air hole of the cover body, otherwise, the When the sealing rotating body is rotated away from the water outlet and the air hole, the water outlet stop cushion and the air hole stop cushion can be slightly loosened and no longer adhere to the top surface of the cover body, which can facilitate the rotation of the seal Spin.

The advantage of the cup cover of the present invention is that when the sealing rotary body rotates on the cover body, the bottom of the snap flange of the cover body is gradually thinned and the thickness is gradually inclined, so that the water outlet of the sealing rotary body can be used to stop the leakage pad and The air hole anti-leakage pad gradually presses on the water outlet and air hole of the cover body. When the positioning protrusion of the cover body is inserted into the positioning card slot of the sealing rotary body for positioning, the function of completely sealing water and air can be achieved , Can prevent the liquid in the cup from leaking out, and the cup lid can be used to drink the liquid in the cup body directly from the water outlet on the cup body without removing from the cup body. The risk of loss is more convenient in use.
