Abstract

end. The technical field to which the invention described in the claims belongs.

The present invention relates to a cup lid, in particular characterized in that the sealing means formed in the opening.

I. The technical problem the invention is trying to solve.

The lid used in the portable cup is inclined at the top surface and has a functional structure in which an opening is formed at the lower side of the inclined top surface so that the liquid does not easily flow out when being carried. Since it is impossible to prevent the outflow of oil, recently, a plug is formed in this opening portion so as to be slidably opened and closed.

However, this stopper only allows the opening of the opening, and there is no sealing function, so the inconvenience of having to carry it with the cup upright, the liquid spilling out when the cup falls down, and the inclination during the drink There is a disadvantage that the stopper comes down to close the top surface.

All. The gist of the solution of the invention.

Therefore, the double cup lid of the present invention seeks for convenience by taking a sealing means at the opening to prevent the leakage of liquid completely, and opening and closing the stopper by a rotation method by shaft coupling to fix the lid when opening and closing. By doing so, the user's convenience is intended.

Cup lid.

Description

Cup lid {A cup cover}

The present invention relates to a lid used for a cup, and in particular, a sealing means for openings is made so as to completely block the outflow of liquid when carrying.

In the case of a cup having a double structure of an inner layer and an outer layer, it is commonly used as a portable cup for a car in a state of containing a drink because it is possible to keep warm or cool by an air layer filled between the inner layer and the outer layer.

Therefore, in the case of a cup lid that can be utilized for this purpose, the top surface of the lid is inclined as shown in FIG. 8, and the opening 100 is formed to drink a drink to the lower side of the inclined top surface. When the vehicle is carried by the shaking of the vehicle, the liquid swells and flows out through the opening 100, so that the liquid can be easily flowed back through the opening 100 so as to be easily carried in the vehicle. .

However, the drawback of this is that when the vehicle is severely shaken, the liquid is so swelled that the fluid flows out through the opening 100. Recently, as shown in FIG. 9, the upper surface of the opening 100 is slidably formed. Although there is one to solve the above disadvantages by forming a stopper 200 to be opened and closed, the disadvantage of this stopper 200 there is a gap between the opening 100 and the stopper 200, only blocking the opening 100 Because there is only a function, there is no sealing function, when the double cup is knocked down, liquid is leaked through the gap, and the stopper 200 can be closed down by closing the inclined top surface while drinking a drink. There is discomfort.

Therefore, the present invention has been devised to solve the above-mentioned problems. The object of the present invention is to form a stopper in the lid, which can be sealed in the opening and prevents the opening and closing of the stopper. It is intended to provide convenience of

To this end, the cup lid of the present invention forms a concave concave part to the upper surface of the cap to form an opening at the lower end thereof, and the upper part of the opening is axially coupled to both sides of the concave part so as to be opened and closed in a rotary manner. A stopper is formed to be fixed and a packing for sealing the opening is formed inside the stopper.

Hereinafter, with reference to the accompanying drawings will be described in detail the most preferred embodiment of the present invention. First, in describing the drawings, the same reference numerals are used to refer to the same elements even though they are shown in different drawings.

1 and 2, the cup lid of the present invention has a concave inlet 10 which is inclined toward an upper surface thereof, and an opening 20 for outflow of liquid to the lower end thereof is formed, and In the upper portion is formed a stopper 30 is axially coupled to the groove (10a) formed on both sides of the concave inlet portion 10 to be opened and closed by 180 ° rotation to form a packing 31 formed on the inside of the stopper 30 is the opening It is characterized by being inserted into (20) to be sealed.

At this time, the inclined stepped jaw 21 is formed at the edge of the opening 20, and the protruding jaw for entering and seating through the inclined stepped 21 at the edge of the packing 31 inserted into the opening 20 ( 31a) is formed to prevent any missing of the packing 31 inserted into the opening 20.

In addition, the end of the stopper 30 is protruded to the upper end is formed with a locking portion 33 of the structure in which the front end is rolled outwards is caught on the edge surface of the lid on which the opening 20 is located when the opening 20 is blocked. The front end of the part 33 is locked so that the closed stopper 30 can be fixed so that any opening of the stopper 30 can be prevented. In this case, the locking part 33 for improving the fixing force of the stopper 30 is prevented. The protruding portion (33a) is formed at the tip of the.

In addition, when opening the stopper 30, when the stopper 30 is flipped backward and rotated to 180 °, the outer edge of the locking portion 33 is fixed to the rear of the lid edge so as to be fixed to the lid edge of the opposite side where the opening 20 is located. A cutout portion 50 having a width corresponding to the stopper 30 is formed on the surface, and a lid corresponding to the outer side of the stopper portion 33 and the lid corresponding to the stopper portion 33 for durability in the state seated on the cutout portion 50. Fixing means is formed on the rim surface of the, as the fixing means in the present invention is to take the shape of the groove 34 and the projection 35.

Meanwhile, the method of fixing the stopper 30 to the rim surface of the lid when opening and closing the stopper 30 can be fixed by using the elastic force peculiar to the plastic because the lid of the present invention is made of a plastic material, and also fixed Can be disassembled using the same elastic force.

In addition, the concave inlet 10 is formed with a vent hole 40 to the rear of the opening 20 so that the liquid can flow out smoothly when drinking the beverage through the opening 20, stopper 30 When closing, a packing 32 is formed inside the stopper 30 to be in close contact with the ventilation hole 40 as a means for preventing the leakage of the liquid through the ventilation hole 40 and increases the adhesion of the packing 32. For this purpose, the inclined stepped portion 41 is formed on the edge of the vent hole 40 as in the case of the opening portion 20.

On the other hand, in the case of the packing 31, 32 formed on the stopper 30, because the material of the stopper 30 is a hard body, but is formed of a soft body, the stopper 30 is the packing after the primary molding using the hard body ( 31) 32 is produced by a double injection method made through the secondary molding process.

Therefore, the cup lid of the present invention configured as described above may be sealed in the opening 10 by forming the packing 31 and 32 which are inserted into the opening 10 and the ventilation hole 40 in close contact with the stopper 30. Therefore, it is possible to completely prevent the leakage of the liquid when carrying the cup, the stopper 30 is to be opened and closed rotationally, and the locking portion 33 is fixed to the edge of the lid when opening and closing the stopper (30) Since the state of being opened and closed can be maintained, the opening and closing of the stopper 30 can be prevented.

As described above, the cup lid of the present invention can completely prevent the outflow of liquid due to the sealing function at the opening, so that the cup can be freely carried, and the opening and closing of the cap can be prevented, so that the cap is closed while drinking a drink. There is an advantage that can provide convenience in use by preventing that.
