In a similar way, the design is also used for improving the heat preservation performance and facilitating the turnover after tearing, so that good avoidance is achieved.
As shown in the figures 1-2 of the drawings,
the lid cover plate 10 is provided with a cover-lifting slot 101 formed by downward sinking, and the cover-lifting lid 20 capable of being torn and turned over relative to the cup cover plate 10 is clamped in the cover-lifting slot 101. A cover-lifting clamping groove 101 is directly formed downwards on the cup cover plate 10, which simplifies the whole structure, and meanwhile, the designed cover-lifting clamping groove 101 can be used for fixing the torn turnover cover 20 after being turned over, so as to avoid the interference of the torn turnover cover 20
Further, as shown in fig. 2, the peelable flip-top lid 20 of the present embodiment includes a closing plate 2001, wherein a contact protrusion 2011 protruding upward is disposed on an upper surface of the closing plate 2001, and a molding groove 2021 corresponding to the contact protrusion 2011 is disposed on a lower surface of the closing plate 2001.
As shown in fig. 1, 2 and 4, the cover-lifting slot 101 has a first mating surface mating with the contact surface 201a and a second mating surface mating with the slope 201b, which is convenient for pulling the tearable flip cover 20 out of the cover-lifting slot 101, so as to avoid the situation that the tearable flip cover 20 is difficult to be pulled out due to vacuum formed between the tearable flip cover 20 and the slot bottom of the cover-lifting slot 101.
The convex part and the forming groove 2021 corresponding to the convex part are adopted, so that materials can be saved, and the weight of the cup cover can be lightened.
Next, as shown in fig. 2, a contact surface 201a inclined forward from top to bottom and a slope surface 201b connected between a top side of the contact surface 201a and an upper surface of the closure plate 200 are provided on the contact protrusion 2011.
The contact surface 201a forms an angle of 91-100 deg. with the upper surface of the cup cover plate, which is also designed to facilitate demolding.
Specifically, as shown in fig. 2 and 6, the tear line includes a U-shaped section 10a far away from the turning force-receiving connection point 40 side and arc-shaped sections 10b at both ends of the U-shaped section 10a, a tearable connection point 50 is formed between the U-shaped section 10a and the arc-shaped sections 10b, and the two tearable connection points 50 are symmetrically distributed about the axis of the drink hole 30, and a vertical distance one L1 from the tearable connection point 50 to the bottom of the U-shaped section 10a is greater than a vertical distance two L2 from the tearable connection point 50 to the turning force-receiving connection point 40.
As shown in fig. 3-4, an inner convex locking part 100a is provided on the lower side of the inner wall of the annular part 100, and when the cup cover is covered on the cup mouth of the pulp cup, the inner convex locking part 100a is located on the lower side of the outer convex part of the outer wall of the cup mouth of the pulp cup, that is, the inner convex locking part 100a and the outer convex part form a sealing lock, so that liquid leakage is avoided.
The cup cover plate is also provided with an air outlet hole 102 far away from the tearable flip-top 20.
Fig. 7 shows the tearable flip-top 20 in a state where it is torn along the tear line and flipped.
Example two
The peripheral side 200 forms a right angle or an obtuse angle with the wall of the drinking hole 30.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
