Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

Example 1 (conical paper cup) 

As shown in FIGS. 1-4 , the cup is composed of a cup bottom 1 , a cup body 2 , a first cover flap 4 , a second cover flap 5 and a third cover flap 6 . The cup opening of the cup body 2 extends upwards and has three equally divided (equally divided 360 degrees) foldable flaps for sealing the cup mouth, i.e. the first flap 4, the second flap 5 and the third flap Petal 6, the three flaps (4, 5, 6) are continuous wavy (∧-shaped and ∨-shaped combined connection), the flaps (4, 5, 6) have the same size, structure and shape, and the flaps (4, 5, 6) After being folded into the mouth of the cup, the flaps (4, 5, 6) are superimposed and fastened together to seal the mouth of the cup so that the liquid in the cup will not flow out, and the flaps (4, 5, 6) 6) By folding and opening, the lid and opening of the cup mouth can be realized. the

The first cover flap 4 is composed of a first button 41, a first gap 42, a first folding indentation 43, a first pressure flap 44, a first pressure receiving strip 45, a first pressure groove 46, a first fold indentation 47, The first pressure flap 48 and the first pressing groove 49 are composed; the second cover flap 5 is composed of the second button 51, the second gap 52, the second folding indentation 53, the second pressure flap 54, and the second pressure strip 55 , the second pressure groove 56, the second fold indentation 57, the second pressure flap 58 and the second pressure groove 59; the third cover flap 6 is composed of the third button 61, the third gap 62, the third folding pressure Mark 63 , third pressure flap 64 , third compression strip 65 , third compression groove 66 , third fold indentation 67 , third compression flap 68 and third compression groove 69 .

Taking the first cover flap 4 as an example, a first gap 42 is provided on the ∧-shaped top of the cover flap. One side of the first gap 42 is a first pressure flap 44, and the end of the first pressure flap 44 is a first button 41 ( arc-shaped), the other side of the first gap 42 is the first pressure flap 48, the first pressure flap 48 is provided with a first fold indentation 47, above the first fold indentation 47 is the first pressure strip 45, the first pressure strip 45 can be folded relative to the first pressure flap 48, and the first pressure strip 45 is also provided with an arched first pressure groove 46, and the first cover flap 4 (the second cover flap 5 The same as the third cover flap 6) is provided with an arc-shaped first folding indentation 43, the first cover flap 4 is also provided with an arched first pressing groove 49, and the second cover flap 5 is provided with an arched The second press-fit groove 59 is provided, and the third cover flap 6 is provided with an arched third press-fit groove 69 . the

The first cover flap 4, the second cover flap 5 and the third cover flap 6 are folded into the cup mouth through the first folding indentation 43, the second folding indentation 53 and the third folding indentation 63 respectively. After folding, the first cover Petal 4, the second flap 5 and the third flap 6 are stacked together in the same direction, and the pressure flap of the latter flap is pressed on the pressure groove of the pressure strip of the previous flap, that is, the second pressing The groove 59 and the first pressing groove 46 are arched (convex) to each other to form a pair of pressing together, and the third pressing groove 69 and the second pressing groove 56 are arched (convex) to each other to form a pair of pressing together. The pressing groove 49 and the third pressing groove 66 are arched (convex) to each other to form a pair of pressing together, because the mutual convex pressing force is increased, and it is more sealed. The mouth is sealed to become a cup with a lid (see Figure 2 and Figure 5). the

Because the cup is in the shape of a truncated cone, the diameter of the mouth of the cup is larger than that of the bottom of the cup. The folded area of the cover flap is larger than the area of the mouth of the cup. the

The fold and position indentations are usually thinner than the cup and compression flap. the

working principle

The cup is open when it is made (see Figure 1), and liquid (such as soybean milk) is put into it when in use, then the cover flap is folded to seal the mouth of the cup (see Figure 2), and the straw is inserted at the cross-marked 3.

features

Save the original plastic cover. The part extending from the edge of the cup is called the flap, and the flaps are combined to form a lid, which is convenient and easy to use.
