[0003] Based on this, it is necessary to provide a lid and a packaging container to facilitate controlling the amount of liquid poured out, thereby improving the convenience of use.

[0004] According to one aspect of the present application, an embodiment of the present application provides a lid for a packaging container. The packaging container has a receiving cavity and an opening communicating with the receiving cavity. The lid includes:

[0025] In one embodiment, the cover body further includes a first blocking member provided on the covering member; in the covering state, the first blocking member blocks the liquid outlet member; and / or

[0026] The cover body further includes a second blocking member provided on the covering member; in the covering state, the second blocking member blocks the air inlet member.

[0033] The cover body, the liquid outlet member, and the air inlet member are of an integral structure.

[0034] According to another aspect of the present application, an embodiment of the present application provides a packaging container including the cover body in any one of the above embodiments.

[0035] In the above-mentioned cover body and packaging container, the cover body at least includes a cover main body, a liquid outlet member, and an air inlet member. The air inlet member is located on the first side of the cover body, and the liquid outlet member is located on the second side of the cover body. The first side of the cover body can be regarded as the inner side of the cover body approximately, and the second side of the cover body can be regarded as the outer side of the cover body approximately. That is to say, the liquid outlet member is arranged on the outer side of the cover body, and the air inlet member is arranged on the inner side of the cover body. Thus, by providing the liquid outlet member, the pouring amount can be correspondingly controlled by controlling the size of the liquid outlet channel of the liquid outlet member. When pouring out the liquid in the accommodating cavity of the packaging container through the liquid outlet channel of the liquid outlet member, the liquid flows out from the liquid outlet channel under the action of its gravity. At the same time, since the end of the liquid outlet member far away from the cover body is approximately located below the air inlet member, during the outflow process of the liquid, the gas on the outside can enter the accommodating cavity through the air inlet channel of the air inlet member, so that the air pressure in the accommodating cavity will not change significantly, which is conducive to the liquid in the accommodating cavity flowing out from the liquid outlet channel in a more stable state. Further, when the cross-sectional area of the liquid outlet channel has a decreasing trend along the extending direction of the liquid outlet channel and pointing away from the cover main body, it is beneficial to reduce the liquid outflow speed, and further improve the stability of the liquid outflow, and facilitate the control of the liquid outflow amount. When the cross-sectional area of the air inlet channel has a decreasing trend along the extending direction of the air inlet channel and pointing away from the cover main body, it is beneficial to increase the air inlet speed, and then improve the situation where the liquid state is unstable due to the formation of a vacuum environment in the accommodating cavity, and facilitate the liquid to flow out more stably. When the cross-sectional area of the liquid outlet channel has a decreasing trend along the extending direction of the liquid outlet channel and pointing away from the cover main body, and the cross-sectional area of the air inlet channel has a decreasing trend along the extending direction of the air inlet channel and pointing away from the cover main body, it is beneficial to reduce the air inlet speed while reducing the liquid outflow speed, improve the situation where the liquid state is unstable due to the air inlet speed being lower than the liquid outflow speed, and then improve the stability of the liquid while facilitating the liquid outflow and air inlet. Therefore, the cover body and the packaging container provided by the embodiments of the present application are convenient for controlling the amount of the poured liquid and improve the convenience of use. In addition, it is also convenient to realize the recycling of the cover body.

[0061] To make the above - mentioned objects, features and advantages of the present application more obvious and understandable, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0062] Currently, when a user uses a packaging container to pour out the liquid contained therein, it is difficult to control the amount of liquid poured out, resulting in inconvenient use. Taking a packaging container for flavoring food as an example, the bottle cap of the flavoring food container is usually configured as a bottle cap with a pull - ring structure. In order to control the amount of liquid poured out, it is usually adapted by controlling the size and shape of the pull - ring structure. However, on the one hand, if the area of the pull - ring structure is too small, it is easy to cause unsmooth liquid discharge; on the other hand, if the area of the pull - ring structure is too large, the smoothness of liquid discharge can be improved, but it is difficult to control the amount of liquid poured out.

[0063] Based on this, the embodiments of the present application improve the structure of the lid and the related liquid - discharging method to facilitate controlling the amount of liquid poured out, thereby improving the convenience of use.

[0064] Figure 1 FIG. shows a schematic structural diagram of a packaging container 10 provided by some embodiments of the present application; Figure 2 FIG. shows a three - dimensional structural diagram of a lid 200 provided by some embodiments of the present application; Figure 3 FIG. shows a cross - sectional structural diagram of a lid 200 provided by some embodiments of the present application; for the sake of convenience of explanation, only the content related to the embodiments of the present application is shown.

[0065] Please refer to Figures 1 to 3 , the embodiments of the present application provide a lid 200 for a packaging container 10. The lid 200 includes a lid body 210, a liquid - discharging member 220 and an air - inlet member 230.

[0066] The packaging container 10 is a device for storing liquids. The liquid can be edible oil such as peanut oil or soybean oil, or edible seasonings such as soy sauce or light soy sauce, or other liquids that need to be stored. The packaging container 10 has a receiving cavity Q and an opening w communicating with the receiving cavity Q, and the receiving cavity Q can be used to hold the liquid. Specifically, the packaging container 10 may include a bottle body 100, on which a bottle mouth portion 110 is provided. The bottle body 100 has a receiving cavity Q, and the bottle mouth portion 110 has an opening w communicating with the receiving cavity Q. The lid body 200 can be fitted to the bottle mouth portion 110 to cover the opening w. In Figure 1 it, the approximate shape and approximate position of the bottle mouth portion 110 are schematically shown by a dashed line, and the approximate positions of the opening w and the receiving cavity Q are schematically shown by dashed arrows.

[0067] The lid body 210 is the main structure of the lid body 200. The lid body 210 is used to cover the opening w. The lid body 210 has a first side c1 facing the receiving cavity Q and a second side c2 opposite to the first side c1. The first side c1 and the second side c2 are oppositely arranged along a first direction F1. The first side c1 of the lid body 200 can be regarded as the inner side of the lid body 200, and the second side c2 of the lid body 200 can be regarded as the outer side of the lid body 200. The lid body 210 is provided with a first hole u1 and a second hole u2 both communicating with the opening w. The first hole u1 and the second hole u2 are independent of each other. That is, the first hole u1 and the second hole u2 are not directly connected, and the contour edges of the first hole u1 and the second hole u2 are independent of each other. Exemplarily, the first hole u1 and the second hole u2 can both be circular holes.

[0068] Exemplarily, with reference to Figure 3 , the lid body 210 may include a first wall 211. The first wall 211 has a first surface s1 and a second surface s2 oppositely arranged along the first direction F1. The first surface s1 is provided on the first side c1 of the lid body 210, and the second surface s2 is provided on the second side c2 of the lid body 210. Correspondingly, the first hole u1 and the second hole u2 can be opened on the first wall 211, and the first hole u1 and the second hole u2 both penetrate the first wall 211 along the first direction F1. That is, the first hole u1 and the second hole u2 both penetrate the first surface s1 and the second surface s2. The first wall 211 can be covered at the opening w of the bottle mouth portion 110, and the first wall 211 and the bottle mouth portion 110 can be snap-fitted or other fitting methods that can relatively fix the first wall 211 and the bottle mouth portion 110, which are not specifically limited here.

[0069] The liquid discharging member 220 is a member for cooperating to pour out liquid. The liquid discharging member 220 is provided on the second side c2. The liquid discharging member 220 has a liquid discharging channel p1 communicating with the second hole u2. Specifically, the liquid discharging member 220 can be provided on the second surface s2 of the first wall 211. The liquid discharging channel p1 has a first opening k1 and a second opening k2 communicating with each other, and the second opening k2 is connected to the second hole u2. During the process of the liquid flowing out from the liquid discharging channel p1, the liquid located in the accommodation cavity Q flows into the second hole u2 and the second opening k2 through the opening w, then enters the liquid discharging channel p1, and then flows out from the first opening k1. The first opening k1 can be regarded as the liquid outlet, and the second opening k2 can be regarded as the liquid inlet. In the illustration, it can be generally regarded that the second opening k2 and the second hole u2 are located at the same position.

[0070] The size of the liquid discharging channel p1 can be set according to specific usage requirements. In this way, by providing the liquid discharging member 220 on the cover body 210, the pouring amount can be correspondingly controlled by controlling the size of the liquid discharging channel p1 of the liquid discharging member 220.

[0071] The air inlet member 230 is an air inlet component for cooperating with the liquid discharging member 220 to discharge liquid. The air inlet member 230 is provided on the first side c1. The air inlet member 230 has an air inlet channel p2 communicating the first hole u1 with the opening w. Specifically, the air inlet member 230 can be provided on the first surface s1 of the first wall 211. The air inlet channel p2 has a first air hole f1 and a second air hole f2 communicating with each other. The first air hole f1 is connected to the first hole u1, and the second air hole f2 is connected to the opening w. In the illustration, it can be generally regarded that the first air hole f1 and the second hole u2 are at the same position.

[0072] When the air inlet member 230 is located on the first side c1 of the cover body 200 and the liquid discharging member 220 is located on the second side c2 of the cover body 200, the first side c1 of the cover body 200 can be generally regarded as the inner side of the cover body 200, and the second side c2 of the cover body 200 can be generally regarded as the outer side of the cover body 200. In this way, when pouring out the liquid in the accommodation cavity Q of the packaging container 10 by means of the liquid discharging channel p1 of the liquid discharging member 220, the liquid flows out from the liquid discharging channel p1 under the action of its gravity. At the same time, since the end of the liquid discharging member 220 far from the cover body 200 is generally located below the air inlet member 230, during the outflow process of the liquid, the gas on the outside can enter the accommodation cavity Q through the air inlet channel p2 of the air inlet member 230, so that the air pressure in the accommodation cavity Q will not change significantly, which is beneficial to the liquid in the accommodation cavity Q flowing out from the liquid discharging channel p1 in a more stable state. In this way, the liquid can flow out of the accommodation cavity Q from the liquid discharging channel p1, and the gas can flow into the accommodation cavity Q from the air inlet channel p2. The liquid discharging member 220 and the air inlet member 230 cooperate with each other to enable the liquid to flow out smoothly.

[0073] Define at least one of the liquid outlet channel p1 and the air inlet channel p2 as the target channel. Along the extending direction of the target channel and pointing away from the cover body 210, the cross-sectional area of the target channel has a decreasing trend. That is to say, the liquid outlet channel p1 can be the target channel, or the air inlet channel p2 can be the target channel, or both the liquid outlet channel p1 and the air inlet channel p2 are the target channels.

[0074] It should be noted that the "decreasing trend" can include phased decreases, such as decreasing first, then remaining unchanged, and then decreasing again; it can also include continuous decreases, such as a consistent decreasing speed or decreasing rapidly first and then slowly. Taking the decreasing trend of decreasing first, then remaining unchanged, and then decreasing again as an example, the decreasing trend is divided into three stages: the "decreasing first" stage, the "remaining unchanged" stage, and the "decreasing again" stage. That is to say, the overall trend is decreasing.

[0075] When the liquid outlet channel p1 is the target channel, along the extending direction of the liquid outlet channel p1 and pointing away from the cover body 210, the cross-sectional area of the liquid outlet channel p1 has a decreasing trend. At this time, it is beneficial to reduce the liquid outlet speed, thereby further improving the stability of liquid outflow and facilitating the control of the liquid outflow volume. In the embodiment of the present application, the direction along the extending direction of the liquid outlet channel p1 and pointing away from the cover body 210 is the first direction F1.

[0076] When the air inlet channel p2 is the target channel, along the extending direction of the air inlet channel p2 and pointing away from the cover body 210, the cross-sectional area of the air inlet channel p2 has a decreasing trend. At this time, it is beneficial to increase the air inlet speed, thereby improving the situation where the liquid state is unstable due to the formation of a vacuum environment in the accommodation cavity Q, and facilitating the more stable outflow of the liquid. At the same time, due to a certain air inlet speed, pressure can also be exerted on the liquid to accelerate the outflow of the liquid from the liquid outlet channel p1. In addition, it is more difficult for the liquid to flow out from the air inlet channel p2. In the embodiment of the present application, the direction along the extending direction of the air inlet channel p2 and pointing away from the cover body 210 is the opposite direction of the first direction F1.

[0077] When both the liquid outlet channel p1 and the air inlet channel p2 are the target channels, along the extending direction of the liquid outlet channel p1 and pointing away from the cover body 210, the cross-sectional area of the liquid outlet channel p1 has a decreasing trend; along the extending direction of the air inlet channel p2 and pointing away from the cover body 210, the cross-sectional area of the air inlet channel p2 has a decreasing trend.

[0078] It can be understood that when the air inlet speed is lower than the liquid outlet speed, it may cause the air pressure in the accommodation cavity Q to briefly form a vacuum environment, resulting in unstable situations such as liquid splashing, oscillation, or turbulence, and further making the liquid may be in an unstable state, thus being unfavorable for controlling the liquid outflow volume.

[0079] When both the liquid outlet channel p1 and the air inlet channel p2 are target channels, it is beneficial to reduce the air inlet speed while reducing the liquid outlet speed, improve the unstable liquid state caused by the air inlet speed being lower than the liquid outlet speed, and further improve the stability of the liquid while facilitating liquid outlet and air inlet.

[0080] Therefore, the cover body 200 provided by the embodiment of the present application, by arranging a liquid outlet member 220 and an air inlet member 230 on different sides of the cover body 210 and correspondingly controlling the cross-sectional area of the liquid outlet channel p1 and / or the air inlet channel p2, enables air intake while discharging liquid, and the liquid outlet process and the air intake process have a certain stability. In this way, it is convenient to control the amount of liquid poured out and improves the convenience of use. Even if there is a situation where liquid covers the air inlet channel p2, due to the cross-sectional area of the target channel being configured to have a corresponding decreasing trend, the air inlet channel p2 can still intake air and block the liquid from flowing into the air inlet channel p2. In addition, compared with the cover structure adopting a pull-ring type structure, the cover body 200 provided by the embodiment of the present application not only has a simple structure and is easier to control the outflow amount of the liquid, but also can improve the problem that it is difficult to recycle after the pull-ring type structure is separated from the cover structure, and is more convenient to realize the recycling of the cover body 200.

[0081] In some embodiments, please continue to refer to Figure 3 , along the extending direction of the target channel and pointing away from the cover body 210, the cross-sectional area of the target channel gradually decreases. That is, the cross-sectional area of the target channel has been decreasing.

[0082] The gradual decrease can be a decrease that is fast first and then slow, or a decrease that is slow first and then fast, or a decrease in an irregular and fluctuating manner. Of course, it can also be a decrease in a regular manner, as long as the cross-sectional area of the target channel has been decreasing, and no specific limitation is made here.

[0083] Exemplarily, Figure 3 It shows the situation where the cross-sectional area of the liquid outlet channel p1 gradually decreases along the first direction F1 and the situation where the cross-sectional area of the air inlet channel p2 gradually decreases along the direction opposite to the first direction F1.

[0084] In this way, when the liquid outlet channel p1 is the target channel, by configuring the decreasing trend of the cross-sectional area of the liquid outlet channel p1 to gradually decrease, the liquid outlet speed can be continuously controlled, and further the stability of the liquid outlet is improved. When the air inlet channel p2 is the target channel, by configuring the decreasing trend of the cross-sectional area of the air inlet channel p2 to gradually decrease, the air inlet speed can be continuously controlled, which is further beneficial to air intake. Thus, by controlling the specific decreasing trend of the cross-sectional area of the target cross-section, it is further convenient to control the liquid outflow amount.

[0085] In some embodiments, with continued reference to Figure 3 , along the extending direction of the target channel and pointing away from the cover body 210, the cross-sectional area of the target channel decreases according to a first preset rule. That is to say, the cross-sectional area of the target channel decreases regularly. The first preset rule may be that along the extending direction of the target channel and pointing away from the cover body 210, the cross-sectional area of the target channel forms an arithmetic sequence, a geometric sequence, or other rules. For example, under the first preset rule, along the extending direction of the target channel and pointing away from the cover body 210, the cross-sectional area of the target channel may decrease linearly.

[0086] Exemplarily, Figure 3 schematically shows the situation where the cross-sectional area of the liquid outlet channel p1 has been decreasing regularly along the first direction F1, and the situation where the cross-sectional area of the air inlet channel p2 has been decreasing regularly along the direction opposite to the first direction F1. The rule for the decrease in the cross-sectional area of the liquid outlet channel p1 and the rule for the decrease in the cross-sectional area of the air inlet channel p2 may be the same or different, without specific limitation.

[0087] In this way, by further controlling the decreasing trend to be regularly decreasing, the continuity control of the corresponding fluid is further improved, and further, it is more convenient to control the liquid outflow rate.

[0088] Figure 4 Fig. shows a schematic cross-sectional structure diagram of the cover body 200 provided in some other embodiments of the present application; for the convenience of description, only the content related to the embodiments of the present application is shown.

[0089] In some embodiments, please refer to Figure 4 , the air inlet channel p2 includes a first air inlet section p21 and a second air inlet section p22 that are sequentially connected along the direction from the second side c2 to the first side c1. One end of the first air inlet section p21 away from the second air inlet section p22 is connected to the first hole u1, and one end of the second air inlet section p22 away from the first air inlet section p21 is connected to the opening w. Along the extending direction of the air inlet channel p2 and pointing away from the cover body 210, the cross-sectional area of the first air inlet section p21 remains unchanged, and the cross-sectional area of the second air inlet section p22 has a decreasing trend.

[0090] Specifically, a first air hole f1 as described above is provided at one end of the first air inlet section p21 away from the second air inlet section p22, and a second air hole f2 as described above is provided at one end of the second air inlet section p22 away from the first air inlet section p21. In the embodiments of the present application, the direction along the extending direction of the air inlet channel p2 and pointing away from the cover body 210 is the direction opposite to the first direction F1.

[0091] Thus, by configuring the intake passage p2 into a first intake section p21 and a second intake section p22, the intake passage p2 can have a certain intake volume by means of the first intake section p21, and the intake speed can be controlled by means of the second intake section p22. In addition, since the second intake section p22 is closer to the inside of the accommodation chamber Q, it can further prevent liquid from flowing into the intake passage p2. In this way, the convenience of use is further improved.

[0092] In some embodiments, please continue to refer to Figure 4 , along the extending direction of the intake passage p2 and pointing away from the cover body 210, the cross-sectional area of the second intake section p22 gradually decreases.

[0093] Thus, by configuring the decreasing trend of the cross-sectional area of the second intake section p22 to gradually decrease, not only can the intake speed be continuously controlled, which is further beneficial to intake, but also the difficulty of liquid flowing into the intake passage p2 can be further increased. In this way, the convenience of use is further improved.

[0094] In some embodiments, please continue to refer to Figure 4 , along the extending direction of the intake passage p2 and pointing away from the cover body 210, the cross-sectional area of the second intake section p22 decreases according to a second preset rule.

[0095] Thus, by controlling the decreasing trend of the cross-sectional area of the second intake section p22 to continuously decrease regularly, the continuous control of the gas is further improved, and the difficulty of liquid flowing into the intake passage p2 is further increased. Furthermore, it is more convenient to control the liquid outflow volume. In this way, the convenience of use is further improved to a greater extent.

[0096] It should be noted that the way of gradually decreasing the cross-sectional area of the second intake section p22 and the way of decreasing according to the second preset rule can be understood by referring to the "gradually decreasing" way and the "decreasing according to the first preset rule" way involved in the foregoing some embodiments, and will not be elaborated here. Among them, the first preset rule and the second preset rule can be the same or different.

[0097] Figure 5 shows Figure 3 a structural schematic diagram of the structure shown in the schematic diagram with relevant dimensions marked; Figure 6 shows Figure 4 a structural schematic diagram of the structure shown in the schematic diagram with relevant dimensions marked; For the convenience of description, only the structures related to the embodiments of the present application are shown.

[0098] In some embodiments, please continue to refer to Figure 3 and Figure 4 , and in combination with referring to Figure 5 andFigure 6 The minimum pore diameter of the liquid outlet channel p1 is 3 mm to 8 mm; and / or, the minimum pore diameter of the air inlet channel p2 is 1.5 mm to 3 mm; and / or, the maximum pore diameter of the air inlet channel p2 is 2.5 mm to 4 mm.

[0099] Exemplarily, the minimum pore diameter of the liquid outlet channel p1 is the first pore diameter d1, and the first pore diameter d1 can be 3 mm, 3.2 mm, 3.3 mm, 3.5 mm, 3.8 mm, 4 mm, 4.2 mm, 4.5 mm, 4.8 mm, 5 mm, 5.2 mm, 5.5 mm, 5.8 mm, 6 mm, 6.3 mm, 6.6 mm, 7 mm, 7.3 mm, 7.7 mm or 8 mm. The maximum pore diameter of the air inlet channel p2 is the second pore diameter d2, and the second pore diameter d2 can be 2.5 mm, 2.8 mm, 3 mm, 3.3 mm, 3.6 mm, 3.8 mm or 4 mm. The minimum pore diameter of the air inlet channel p2 is the third pore diameter d3, and the third pore diameter d3 can be 1.5 mm, 1.8 mm, 2 mm, 2.2 mm, 2.6 mm, 2.8 mm or 3 mm.

[0100] Thus, by controlling the minimum pore diameter of the liquid outlet channel p1, it is beneficial to control the liquid output; by controlling the maximum pore diameter of the air inlet channel p2, it is beneficial to increase the air intake; by controlling the minimum pore diameter of the air inlet channel p2, it is beneficial to block the liquid from entering the air inlet channel p2 or adhering to one end of the air inlet channel p2 away from the cover body 210 while having a certain air intake; by simultaneously controlling the minimum pore diameter of the liquid outlet channel p1, the minimum pore diameter of the air inlet channel p2, and the maximum pore diameter of the air inlet channel p2, in addition to the aforementioned advantages, the mutual cooperation of each pore diameter can further facilitate the control of the liquid outflow volume and further improve the user's feeling of controlling the volume.

[0101] In some embodiments, please continue to refer to Figure 3 and Figure 4 The air inlet channel p2 has a first air hole f1 communicating with the first hole u1 and a second air hole f2 communicating with the opening w. The first air hole f1 and the second air hole f2 communicate with each other and are oppositely arranged. The second air hole f2 is configured to be able to block the liquid from flowing into the air inlet channel p2.

[0102] In the embodiment of the present application, the first air hole f1 and the second air hole f2 are oppositely arranged along the first direction F1. The air intake while blocking the liquid can be achieved by controlling the size of the second air hole f2. The liquid can also be blocked by arranging a corresponding blocking mechanism at the second air hole f2. Of course, the second air hole f2 can also be arranged on the side wall of the air inlet member 230. It can be set according to the specific usage situation and is not specifically limited here.

[0103] Thus, by configuring the second air hole f2 to be able to block the inflow of liquid into the air intake passage p2, it is further conducive to the entry of gas into the air intake passage p2.

[0104] In some embodiments, please continue to refer to Figures 3 to 6 , the extending direction of the liquid outlet passage p1 is parallel to the direction from the first side c1 to the second side c2; and / or, the extending direction of the air intake passage p2 is parallel to the direction from the first side c1 to the second side c2.

[0105] In the embodiments of the present application, the extending direction of the liquid outlet passage p1, the extending direction of the air intake passage p2, and the direction from the first side c1 to the second side c2 are all parallel to the first direction F1.

[0106] Thus, by controlling the extending direction of the liquid outlet passage p1 and / or the extending direction of the air intake passage p2, it is not only convenient for processing and manufacturing the cover body 200, but also convenient for the user to use.

[0107] In some embodiments, please continue to refer to Figures 2 to 6 , along the first direction F1, the cross-sectional shape of the liquid outlet passage p1 can be a regular shape or an irregular shape, and the cross-sectional shape of the air intake passage p2 can be a regular shape or an irregular shape. For example, the regular shape can be a circle, a rectangle, a triangle, etc., and the irregular shape can be a shape composed of straight line segments, curved line segments, etc.

[0108] In the embodiments of the present application, along the first direction F1, the cross-sectional shapes of both the liquid outlet passage p1 and the air intake passage p2 are circular. In this way, it is conducive to the flow of the corresponding fluid in the liquid outlet passage p1 and the air intake passage p2.

[0109] Thus, according to the specific usage situation, the cross-sectional shapes of the liquid outlet passage p1 and the air intake passage p2 can be flexibly set.

[0110] Figure 7 Fig. shows the schematic structural diagram of the cover body 200 provided by some other embodiments of the present application in the closed state; Figure 8 Fig. shows Figure 7 the cross-sectional structural diagram of the structure schematically shown; Figure 9 Fig. shows the schematic structural diagram of the cover body 200 provided by some other embodiments of the present application in the open state; Figure 10 Fig. shows Figure 9 the cross-sectional structural diagram of the structure schematically shown; For the convenience of description, only the content related to the embodiments of the present application is shown.

[0111] In some embodiments, please refer to Figures 7 to 10, the cover body 200 further includes a covering member 240 that is mated with the cover main body 210. The cover body 200 has a closed state and an open state. In the closed state, the covering member 240 covers the second side c2 of the cover main body 210, and the covering member 240 and the cover main body 210 define a closed cavity for accommodating the liquid outlet member 220 and the first hole u1. In the open state, the covering member 240 is opened relative to the cover main body 210, and the liquid outlet member 220 and the first hole u1 are exposed on the second side c2 of the covering member 240.

[0112] In this way, by providing the covering member 240, the covering member 240 can be opened when it is necessary to pour out the liquid, and the covering member 240 can be closed when it is not necessary to pour out the liquid. In this way, it is not only convenient for the user to use, but also beneficial to keep the liquid outlet member 220, the air inlet member 230 and the accommodation cavity Q to a certain degree of cleanliness, and can also protect the liquid outlet member 220.

[0113] In some embodiments, please continue to refer to Figures 8 to 10 , the cover body 200 further includes a first plugging member 250 provided on the covering member 240; in the closed state, the first plugging member 250 plugs the liquid outlet member 220; and / or, the cover body 200 further includes a second plugging member 260 provided on the covering member 240; in the closed state, the second plugging member 260 plugs the air inlet member 230.

[0114] Exemplarily, taking Figure 8 as an example, in the closed state, the first plugging member 250 can be inserted into the liquid outlet channel p1, and the second plugging member 260 can be inserted into the air inlet channel p2. Of course, in some other embodiments, it may be that the liquid outlet member 220 is inserted into the first plugging member 250, and the second plugging member 260 covers the first hole u1. It can be set according to the specific usage situation, and no specific limitation is made here.

[0115] In this way, by providing the first plugging member 250 and / or the second plugging member 260, it is beneficial to improve the situation that when the packaging container 10 is subjected to an external force in the closed state, the liquid overflows to the second side c2 of the cover main body 210, and is beneficial to keep the cover body 200 to a certain degree of cleanliness.

[0116] In some embodiments, please continue to refer to Figure 7 and Figure 9 , the covering member 240 is swingably connected to the cover main body 210. That is, in the open state, the covering member 240 and the cover main body 210 are still in a connected state.

[0117] In this way, it is not only beneficial for the user to use, but also beneficial to make the cover body 200 a whole, which is convenient for recycling the cover body 200.

[0118] In some embodiments, please continue to refer to Figure 9 andFigure 10 The liquid outlet member 220 is farther away from the connection between the covering member 240 and the cover body 210 than the air inlet member 230.

[0119] In this way, in the open state, it is convenient for the user to use the packaging container 10 to pour out the liquid.

[0120] In some embodiments, please continue to refer to Figures 2 to 6 and Figures 8 to 10 , the first hole u1 and the second hole u2 are arranged at intervals. That is, the orthographic projection of the liquid outlet member 220 on the reference plane perpendicular to the first direction F1 is spaced apart from the orthographic projection of the air inlet member 230 on the reference plane perpendicular to the first direction F1.

[0121] In this way, by arranging the first hole u1 and the second hole u2 at intervals, the liquid outlet channel p1 and the air inlet channel p2 can be separated farther. In this way, it is beneficial to carry out the liquid outlet process and the air inlet process simultaneously, and further improve the situation where the liquid flows to the air inlet channel p2.

[0122] In some embodiments, please continue to refer to Figures 2 to 6 and Figure 9 , a flanging structure M is provided at one end of the liquid outlet member 220 facing away from the cover body 210.

[0123] Exemplarily, the flanging structure M can be arranged around the edge of the first port k1, and the flanging structure M can have an arc surface that is connected to the inner wall of the liquid outlet channel p1 and protrudes.

[0124] In this way, by providing the flanging structure M, the liquid flowing out from the liquid outlet channel p1 can be guided, and at the same time, the situation where the flowing out liquid adheres to the vicinity of the first port k1 of the liquid outlet channel p1 can also be improved.

[0125] In some embodiments, please continue to refer to Figures 3 to 6 , the inner wall of the liquid outlet channel p1 and the wall of the second hole u2 are connected by means of an arc transition section Y.

[0126] In this way, by providing the arc transition section Y, not only can the liquid flowing into the liquid outlet channel p1 be guided, but also the structural strength of the connection between the liquid outlet member 220 and the cover body 210 can be improved, and the risk of stress concentration can be reduced.

[0127] In some embodiments, please continue to refer to Figures 2 to 6 , a reinforcing portion J is provided on the second side c2 of the cover body 210, and the reinforcing portion J is arranged around the first hole u1.

[0128] Exemplarily, the reinforcing portion J generally forms a protruding structure. The reinforcing portion J can be configured as an annular shape. Specifically, the reinforcing portion J can be arranged around the edge of the first hole u1.

[0129] In this way, by providing a reinforcing portion J around the first hole u1, the flatness at the first hole u1 can be improved, and further the flatness at the first air hole f1 can be improved. Thus, the situation of warping and other deformations near the first hole u1 and near the first air hole f1 can be improved, which is beneficial to keeping the first air hole f1 and the first hole u1 with a certain aperture.

[0130] In some embodiments, please continue to refer to Figures 2 to 6 , the cover body 210, the liquid outlet member 220 and the air inlet member 230 are of an integral structure.

[0131] Integral connection means that two components are connected into a whole instead of two independent components. Exemplarily, the specific connection manner of the integral connection of the cover body 210, the liquid outlet member 220 and the air inlet member 230 can be hot melt welding or integral molding and other connection manners. Integral molding means a whole component formed by an integral molding process with the same material. For example, the cover body 210, the liquid outlet member 220 and the air inlet member 230 can be integrally injection molded. It can be selected according to the specific usage situation, and no specific limitation is made here.

[0132] In this way, by making the cover body 210, the liquid outlet member 220 and the air inlet member 230 of an integral structure, it is not only convenient for manufacturing, but also beneficial to improving the aesthetics.

[0133] Of course, in some other embodiments, all components of the cover body 200 except the covering member 240 can be set as an integral structure. It can be set according to the specific usage situation, and no specific limitation is made here.
