In the figure is shown a collecting bag, which in this example comprises a bag body 1, the bag body 1 having a bag mouth 1.1, the bag body 1 having a bag cavity 1A. The bag mouth 1.1 is also provided with a left ear 1.1A and a right ear 1.1B which are extended and raised upwards. Fig. 3 shows that the bag opening 1.1 is torn through the left ear 1.1A and the right ear 1.1B, and after the bag opening 1.1 is opened, the left ear 1.1A and the right ear 1.1B make the left and right sides of the bag opening extend upwards and bulge and the front and back are sunken downwards.

In the figure, it is shown that, as is preferred, the edges of the left ear 1.1A and the right ear 1.1B are in the shape of a circular arc or an elliptical arc. Meanwhile, the bag opening front recess 1.1C and the bag opening rear recess 1.1D are arc-shaped or elliptic arc-shaped structures, so that the edges of the left ear 1.1A and the right ear 1.1B form smooth transition.

Fig. 3 shows that, as a preference, in this example, the left ear 1.1A and the right ear 1.1B form an oval bell-mouth structure with the mouth 1.1 of the bag.

In this example, the bag mouth 1.1 is a structure which extends and protrudes from left and right directions and is concave from front to back, so that the bag mouth 1.1 can be more attached to the structure shape around the mouth of a human body.

The present invention suggests that in this example, the material for making the bag body 1 is preferably a material capable of both air permeability and saliva barrier, such as non-woven fabric or woven fabric; film or paper is a less preferred material. And may be a composite of one or more of the above materials. In specific implementation, the bag body 1 can be made of conventional mask making materials and making methods.

The present invention suggests that, in this example, the bag body 1 has a two-sided structure having left and right side surfaces. It should be noted that, since the pouch body 1 is made of a soft material, the opened structure shape is not regular.

The utility model suggests that when the collection bag adopts the structure of the fourth embodiment, the left ear 1.1A and the right ear 1.1B can be respectively and fully attached to the inner side surfaces of the left lug 2.1A and the right lug 2.1B by molding the ear shaping piece 1.31.

The utility model suggests that when the collection bag adopts the structure of the fifth embodiment, the support tube adopts the structure of the tenth embodiment. In practice, 4 parts of the upper orifice 2.1 of the supporting tube are respectively and correspondingly inserted into 4 sleeve bags on the outer sides of the left and right ears of the collecting bag to form fixation.

The utility model suggests that when the collection bag adopts the structure of the sixth embodiment, correspondingly, the support tube adopts the structure of the eleventh embodiment. In the implementation, at the bag mouth 1.1 of the collecting bag, the left lug 2.1A and the right lug 2.1B of the upper pipe orifice 2.1 of the supporting pipe are respectively and correspondingly inserted into the bag cavities of the left sleeve bag 1.1A1 and the right sleeve bag 1.1B1 at the outer sides of the left ear 1.1A and the right ear 1.1B to form a fixed structure, and at the bag bottom 1.2 of the collecting bag, the drawstrings 1.3 positioned at the left side 1_1 and the right side 1_2 of the bag body 1 respectively extend from the two sides of the lower pipe orifice 2.21 from the inside of the supporting pipe and then are sleeved on the drawstring fixing pieces 2.41 and 2.42 at the left outer side and the right outer side, so that the bag body 1 is pulled and fixed from the upper pipe orifice 2.1 to the lower pipe orifice 2.21 and the inner bag cavity is simultaneously torn.

In this case, for the best effect, the size of the supporting tube cavity should match the size of the opened bag cavity of the bag body. Fig. 20 shows that the distance between the drawstring fasteners 2.41 and 2.42 should match the lateral width of the inner lumen of the support tube, so that the inner lumen is pulled into a rectangular or square configuration (ensuring that the lumen at the bottom 1.2 of the bag is also open).
