[0029] Embodiment 1:

[0030] See also Figure 1 - Figure 3 As shown, the utility model is a single-cup bag that can be tightened and degraded, comprising: a bag body 1 and a tightening component for tightening the bag opening at the upper end of the bag body 1;

[0031] The tightening assembly includes a folding portion 2 fixed to the upper end of the bag body 1, a draw rope A31, and a tightening rope 4; the folding portion 2 is provided with perforations 3 symmetrically arranged up and down; tightening ropes 4 are arranged in the corresponding perforations 3 up and down; the folding portion 2 is presented as a circular array of multiple wedge-shaped objects at the upper end of the bag body 1.

[0032] In order to avoid the situation in winter or summer when the milk tea cup has a large amount of heat exchange with the outside air due to the unsealed upper port of the bag body 1, thereby causing the taste of the drink in the cup to be lost, during the specific operation, after the milk tea is filled into the cup, the bag mouth of the bag body 1 is first unfolded so that its upper port is in an open state, and then the cup is put into the bag body 1, and then the upper bag mouth of the bag body 1 is tightened by the tightening component to achieve the purpose of sealing the cup inside the bag body 1, thereby achieving the purpose of reducing the heat exchange between the cup and the outside air and prolonging the drinking taste of the drink in the cup.

[0033] like Figure 1 - Figure 3 As shown, the tightening assembly also includes a drawstring A31, and the drawstring A31 is located on the outside of the bag body 1.

[0034] like Figure 1 - Figure 3 As shown, both ends of the pull rope A31 are fixedly connected to the corresponding ends of the tightening rope 4; the middle part of the pull rope A31 presents a semicircular structure; and a fixing knot 311 is provided at the connection between the tightening rope 4 and the pull rope A31.

[0035] In order to achieve the purpose of quickly closing the bag opening, during the specific operation, after the cup is put into the bag body 1, the drawstring A31 is manually pulled, and the two tightening ropes 4 are driven by the drawstring A31 to move in opposite directions, thereby causing the folding part 2 to shrink and move closer, so as to achieve the purpose of quickly closing the bag opening at the upper end of the bag body 1. Finally, the bag body 1 can be taken away by pulling the middle part of the outer end of the drawstring A31.

[0036] Embodiment 2:

[0037] As another implementation mode of the present invention, Figure 4 - Figure 6 As shown, the tightening assembly includes a folding portion 2 , a tightening rope 4 , a connecting rope 322 and a draw rope B32 , and the connecting rope 322 is located inside the bag body 1 .

[0038] like Figure 4 - Figure 6 As shown, the corresponding tightening ropes 4 pass through the side wall of the bag body 1 to the inside of the bag body 1 and are fixed at both ends of the connecting rope 322; the lower end of the connecting rope 322 is commonly fixed with a pressure plate 321; the upper end of the outer surface of the bag body 1 is fixed with symmetrically arranged pull ropes B32.

[0039] In order to achieve the purpose of quickly and conveniently closing the bag opening at the upper end of the bag body 1, during the specific operation, when the cup is put into the bag body 1, the pressing plate 321 is pressed downward by the cup, and then the pressing plate 321 drives the corresponding tightening rope 4 to move in the opposite direction through the connecting rope 322, so as to achieve the effect of contracting the folding part 2, and then achieve the purpose of closing the upper end of the bag body 1. The pressure generated by the cup on the pressing plate 321 can realize the synchronous operation of bagging and closing the bag opening. The whole process is completed in one go with high efficiency. Finally, the bag body 1 can be taken away through the pull rope B32 symmetrically arranged on the outside.

[0040] like Figure 1 and Figure 4 As shown, the middle parts of the drawstring A31 and the drawstring B32 are both fixedly connected with a carrying portion 41, and the carrying portion 41 is used for lifting the bag body 1 by palm.

[0041] In order to prevent the person from feeling uncomfortable or slipping when holding the bag 1 containing the beverage cup for a long time, during the specific operation, a carrying portion 41 is provided in the middle of the pull rope A31 and the pull rope B32, so as to increase the contact area and friction between the pull rope A31 or the pull rope B32 and the palm, thereby eliminating the influence of the pull rope A31 and the pull rope B32 on the palm due to being too thin.

[0042] Embodiment three:

[0043] As another implementation mode of the present invention, Figure 7 As shown, a cross-shaped fold 5 is provided at the bottom of the bag body 1, and the fold 5 is used to fold the bag body 1; the upper end of the bag body 1 is circular, and the lower end of the bag body 1 is square.

[0044] By providing a cross-shaped fold 5 at the bottom of the bag body 1, the user can fold the bag body 1 at will to facilitate storage; by setting the upper end of the bag body 1 to be round and the lower end of the bag body 1 to be square, the stability of the bag body 1 when standing on the table can be improved, and through this structure with upper and lower supporting functions, the bag body 1 can be prevented from collapsing and being damaged when the cup exerts pressure on the pressure plate 321.

[0045] Working principle:

[0046] After the milk tea is filled into the cup, the bag body 1 is first unfolded to open its upper end, and then the cup is placed inside the bag body 1. The upper end of the bag body 1 is then tightened by a tightening component to seal the cup inside the bag body 1, thereby reducing the heat exchange between the cup and the outside air and prolonging the drinking taste of the beverage in the cup.

[0047] After the cup is put into the bag body 1, the drawstring A31 is manually pulled, and the two tightening ropes 4 are driven to move in opposite directions, so that the folding part 2 is contracted and brought closer, so as to quickly close the bag opening at the upper end of the bag body 1. Finally, the bag body 1 can be taken away by pulling the middle part of the outer end of the drawstring A31.

[0048] Alternatively, when putting the cup into the bag body 1, the cup presses the pressing plate 321 downward, and the pressing plate 321 drives the corresponding tightening rope 4 to move in the opposite direction through the connecting rope 322, so as to achieve the effect of contracting the folding portion 2, and then achieve the purpose of closing the upper end of the bag body 1. The pressure generated by the cup on the pressing plate 321 can realize the synchronous operation of bagging and closing the bag mouth, and finally the bag body 1 can be taken away by the pull rope B32 symmetrically arranged on the outside.
