[0002] The packaging container includes a container body for storing an item. In order to facilitate use, a lid assembly is further provided on the container body, which can facilitate the opening and sealing of the container body. In order to further protect the safety of the item stored in the container body and prolong the shelf life, the packaging container can further include a sealing film. The sealing film can be cut open when the packaging container is first opened by a consumer, thereby facilitating the pouring of the item in the container body out of the container body. SUMMARY

[0003] Embodiments of the present application provide a flow guide component, a lid assembly, and a packaging container. In the flow guide component, the structural design of the transition portion and the cutting portion not only ensures the guidance of the transition portion to the cutting portion, but also avoids excessive extrusion of the transition portion to the cutting portion, avoids the influence of the cutting action of the transition portion to the cutting portion, and improves the cutting efficiency and yield of the cutting portion.

[0004] At least one embodiment of the present application provides a flow guide component, comprising: a tube body, the tube body comprising a tube opening and a sealing film sealing the tube opening, the sealing film comprising a main body portion, a weak portion surrounding the main body portion, and a transition portion connecting the main body portion and the weak portion; and a cutting ring, the cutting ring being at least partially located in the tube body and comprising a cutting portion for cutting the sealing film, wherein the orthogonal projection of the cutting portion on the sealing film overlaps the transition portion, and the overlapping area is located within 1 / 3 of the side of the transition portion close to the weak portion.

[0005] For example, in the flow guide component provided by an embodiment of the present application, the cutting portion comprises a cutting surface, the transition portion comprises a transition surface, the transition surface is configured to be in contact with the cutting surface when the cutting portion cuts the sealing film, and the contact area of the cutting surface and the transition surface is located within 1 / 3 of the transition surface close to the weak portion.

[0006] For example, in the flow guide component provided by an embodiment of the present application, within the cross section passing through the central axis of the tube body and the cutting portion and being perpendicular to the sealing film, the cutting surface comprises a first end and a second end, the transition surface comprises a third end and a fourth end, the distance between the third end and the first end along a reference direction is a first distance, the distance between the third end and the fourth end along the reference direction is a second distance, the ratio of the difference between the second distance and the first distance to the second distance is greater than 0 and less than or equal to 1 / 3, and the reference direction is parallel to the sealing film.

[0007] For example, in a flow guiding component provided in one embodiment of the present invention, the ratio is greater than or equal to 10% and less than or equal to 20%.

[0008] For example, in a flow guiding component provided in one embodiment of the present invention, the sealing membrane further includes a thickened portion, which surrounds the weak portion and connects the weak portion and the tube body. Along the central axis of the tube body, the thickness of the thickened portion is greater than the thickness of the weak portion.

[0009] For example, in a flow guiding component provided in an embodiment of the present invention, an inner guiding element is provided on the inner sidewall of the tube body. The inner guiding element includes an internal thread, and the distance by which the thickened portion extends from the inner sidewall of the tube body toward the central axis of the tube body is less than or equal to 2 / 3 of the height of the internal thread.

[0010] For example, in a flow guiding component provided in one embodiment of the present invention, the angle between the transition surface and the surface of the weak part ranges from 120 degrees to 150 degrees.

[0011] At least one embodiment of the present invention provides a cover assembly, including: any of the above-described flow guiding components; and a cap, wherein the tube body further includes an opening opposite to the sealing membrane, and the cap is configured to seal the opening or expose the opening.

[0012] For example, in a cap assembly provided in one embodiment of the present invention, the cap is sleeved on the outer periphery of the tube body and is configured to be rotatable relative to the tube body. The cap includes a driving part, and the cutting ring includes a driven part. The driving part and the driven part are configured such that when the cap rotates relative to the tube body, the driving part and the driven part abut against each other, so that the rotation of the cap drives the cutting ring to rotate and causes the cutting ring to cut the sealing film around the central axis of the tube body.

[0013] At least one embodiment of the present invention provides a packaging container, including the aforementioned cap assembly and container body, wherein the cavity of the container body is isolated from the outside world by the sealing film of the flow guiding component and communicates with the outside world after the sealing film is cut open by the cutting ring.

[0030] When packaging containers include a sealing film, designing the sealing film and lid assembly to simultaneously ensure both airtightness and ease of use, thereby improving the user experience, has become a crucial direction in packaging container design. For example, during the design process of the sealing film, flow guide components, and lid assembly, it is essential to ensure successful cutting of the sealing film during the opening process. Poor cutting can lead to sealing failure, affecting user experience. Furthermore, after the sealing film is cut and opened, it needs to be flipped over to facilitate the pouring of items from the container.

[0031] This utility model provides a flow guiding component, a cap assembly, and a packaging container. The flow guiding component includes a tube body and a cutting ring. The tube body includes a nozzle and a sealing film for sealing the nozzle. The sealing film includes a main body portion, a weak portion surrounding the main body portion, and a transition portion connecting the main body portion and the weak portion. The cutting ring is at least partially located within the tube body and includes a cutting portion for cutting the sealing film. The orthographic projection of the cutting portion onto the sealing film overlaps with the transition portion, and the overlapping area is located in the 1 / 3 region of the transition portion near the weak portion.

[0032] By making the orthographic projection of the cutting part on the sealing film overlap with the transition part, the transition part can guide the cutting part. After partially cutting the sealing film, the overlap between the transition part and the cutting part also facilitates the flipping of the sealing film. By making the overlap area of ​​the orthographic projection of the cutting part on the sealing film and the transition part located in the 1 / 3 area of ​​the transition part closer to the weak part, excessive compression of the cutting part by the transition part can be avoided, the pressure of the transition part on the cutting part can be reduced, the cutting part can be guaranteed to cut the sealing film, and the cutting efficiency and yield of the cutting part can be improved.

[0033] The flow guiding component, cover assembly, and packaging container provided in the embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0034] This utility model provides a flow guiding component and a cover assembly. Figure 1 This is a schematic diagram of the structure of a cover assembly provided in an embodiment of the present utility model; Figure 2 for Figure 1 A schematic cross-sectional view of the cover assembly along the vertical sealing film and through the cut portion; Figure 3A for Figure 2 A partially enlarged schematic diagram of the flow guiding component shown; Figure 3B for Figure 2 The diagram shows a top view of the sealing membrane.

[0035] like Figures 1-3B As shown, the cap assembly 200 includes a flow guide 100 and a cap 210. The flow guide 100 includes a tube body 110 and a cutting ring 120. The tube body 110 includes an opening 111 and a sealing membrane 130 that seals the opening 111. The sealing membrane 130 includes a main portion 131, a weak portion 133 surrounding the main portion 131, and a transition portion 132 connecting the main portion 131 and the weak portion 133. The cutting ring 120 is at least partially located within the tube body 110 and includes a cutting portion 121 for cutting the sealing membrane 130. The orthographic projection of the cutting portion 121 onto the sealing membrane 130 overlaps with the transition portion 132, and the overlapping area is located in one-third of the area of ​​the transition portion 132 near the weak portion 133. Figure 3BThe shaded lines indicate the 1 / 3 region of the transition portion 132 near the weak portion 133. For example, the overlapping region may be located within the 1 / 4 region of the transition portion 132 near the weak portion 133. For example, the overlapping region may be located within the 1 / 5 region of the transition portion 132 near the weak portion 133. In this embodiment of the invention, the 1 / 3 region, 1 / 4 region, or 1 / 5 region respectively refer to approximately 1 / 3, approximately 1 / 4, or approximately 1 / 5 of the region.

[0036] like Figures 1-3B As shown, by making the orthographic projection of the cutting portion 121 on the sealing film 130 overlap with the transition portion 132, the transition portion 132 can guide the cutting portion 121, allowing the cutting portion 121 to cut the weak portion 133 along the transition portion 132, thereby improving the cutting efficiency of the cutting portion 121. Furthermore, after the sealing film 130 is partially cut, the interaction force between the transition portion 132 and the cutting portion 121 facilitates the flipping of the sealing film 130, allowing for better flipping. By ensuring that the overlap area of ​​the orthographic projection of the cutting portion 121 on the sealing film 130 and the transition portion 132 is located in the 1 / 3 region of the transition portion 132 near the weak portion 133, excessive overlap between the cutting portion 121 and the transition portion 132 can be avoided, preventing excessive compression of the cutting portion 121 by the transition portion 132 and the resulting deformation of the cutting portion 121, and avoiding adverse effects of the transition portion 132 on the cutting movement of the cutting portion 121. Thus, through the above structural arrangement, the transition part 132 can minimize the squeezing force of the transition part 132 on the cutting part 121 while guiding the cutting part 121, thereby reducing the impact on the cutting movement of the cutting part 121, ensuring the cutting of the sealing film 130 by the cutting part 121, and improving the cutting efficiency and yield of the cutting part 121.

[0037] For example, if the overlap area between the cutting section and the transition section is large, the transition section will exert a large compressive force on the cutting section. This large compressive force will cause the cutting section to deform, thereby affecting the cutting of the sealing film and causing the sealing film to fail. For a detailed description of the cutting failure, please refer to the section below. Figure 5B The description.

[0038] Figure 4 for Figure 1 The diagram shows a partially enlarged view of the cutting section of the flow guide component cutting the sealing film. (See attached image.) Figures 1-4As shown, the cutting portion 121 includes a cutting surface 1210, and the transition portion 132 includes a transition surface 1321. The transition surface 1321 is configured such that when the cutting portion 121 cuts the sealing film 130, the cutting surface 1210 contacts the transition surface 1321, and the contact area between the cutting surface 1210 and the transition surface 1321 is located in the 1 / 3 region of the transition surface 1321 near the weak portion 133. When the cutting portion 121 cuts the sealing film 130, the cutting surface 1210 abuts against the transition surface 1321, and the transition surface 1321 guides the cutting surface 1210. By ensuring that the contact area between the cutting surface 1210 and the transition surface 1321 is located in the 1 / 3 region of the transition surface 1321 near the weak portion 133, the contact area between the transition surface 1321 and the cutting surface 1210 can be minimized. Therefore, under the premise that the transition surface 1321 guides the cutting part 121, the squeezing force of the transition surface 1321 on the cutting part 121 and the influence on the cutting motion of the cutting part 121 can be reduced, thereby improving the cutting efficiency and yield.

[0039] For example, the contact area between the cut surface 1210 and the transition surface 1321 is located in the 1 / 4 region of the transition portion 132 on the side closer to the weak portion 133. For example, the contact area is located in the 1 / 5 region of the transition portion 132 on the side closer to the weak portion 133.

[0040] In some examples, such as Figure 3A and Figure 4 As shown, the tip 121a of the cutting portion 121 falls into the weak portion 133 in the orthographic projection of the sealing film 130, so that the tip 121a contacts the sealing film first. Thus, the weak portion 133 of the sealing film 130 can be cut.

[0041] In some examples, such as Figure 2 As shown, the cutting ring 120 includes two cutting portions 121. The two cutting portions 121 are spaced apart in the circumferential direction, so that when the cutting ring 120 rotates downwards in the Z direction and approaches the sealing film, the two cutting portions 121 can simultaneously cut the sealing film 130, thereby increasing the speed of cutting the sealing film 130. Of course, this embodiment of the invention does not limit the number of cutting portions included in the cutting ring; the number of cutting portions can be one or more.

[0042] Figure 5A for Figure 1 The diagram shows the relative position of the tip of the cut portion of the flow guide component and the sealing membrane. To clearly illustrate the relative positional relationship between the cut portion and the sealing membrane, Figure 5A Only the tip of the cutting section and part of the sealing membrane structure are shown. (For example...) Figure 2 , Figure 4 and Figure 5AAs shown, the line connecting the tips 121a of the two cutting portions 121 in the orthographic projection of the sealing film 130 does not pass through the center O of the sealing film 130. For example, when the cutting portion 121 cuts the sealing film 130, the line connecting the initial positions where the tips 121a of the two cutting portions 121 contact the sealing film 130 does not pass through the center O of the sealing film 130.

[0043] In some examples, such as Figure 2 , Figure 4 and Figure 5A As shown, the two cutting portions 121 include a first cutting portion 1211 and a second cutting portion 1212. For example, when the cutting portion 121 cuts the sealing film 130, the initial position where the tip 121a of the first cutting portion 1211 contacts the sealing film 130 is the first starting point P1, and the initial position where the tip 121a of the second cutting portion 1212 contacts the sealing film 130 is the second starting point P2. The line connecting the first starting point P1 and the second starting point P2 does not pass through the center O of the sealing film 130. For example, the line connecting the first starting point P1 and the second starting point P2 around the center O includes a major arc C1 and a minor arc C2. The major arc C1 and the minor arc C2 form a circle with the center O. For example, while the tip 121a of the first cutting portion 1211 cuts the first starting point P1, the tip 121a of the second cutting portion 1212 cuts the second starting point P2. The first cutting part 1211 cuts the sealing membrane 130 along the major arc C1, and the second cutting part 1212 cuts the sealing membrane 130 along the minor arc C2. Since the line connecting the first starting point P1 and the second starting point P2 does not pass through the center O of the sealing membrane 130, when the second cutting part 1212 moves along the minor arc C2 to the first starting point P1, the first cutting part 1211 has not yet moved along the major arc C1 to the second starting point P2. Therefore, when the two cutting parts 121 cut the sealing membrane 130, the sealing membrane 130 can be in an open state relative to the tube body 110, and can also remain connected to the tube body 110 at the connection position P3.

[0044] Figure 5B This is a schematic diagram illustrating the failure of a sealing membrane due to cutting. Figure 5B As shown, during the movement of the second cutting section from the second starting point P02 along the minor arc C02 to the first starting point P01, when the second cutting section is very close to the first starting point P01, the distance between the second cutting section and the first starting point P01 is very small. If the overlap area between the cutting surface of the cutting section and the transition surface of the transition section is large, a large compressive force will be applied to the sealing film at that position (i.e., the sealing film between the second cutting section and the first starting point P01). During the stress process on the sealing film at the above position, on the one hand, the sealing film will undergo plastic deformation under the action of the second cutting section, bending towards the tip of the second cutting section; on the other hand, the second cutting section may pass through the sealing film at that position under the strong compression of the transition surface, causing the sealing film at that position to be unable to be cut by the second cutting section. See also Figure 5BAs shown, the sealing membrane is finally connected to the tube at position P04. Since the sealing membrane is still connected at position P03, the sealing membrane fails to open.

[0045] like Figure 3A , Figure 3B and Figure 4 As shown, the overlapping area or contact area of ​​the cutting surface 1210 of the cutting part 121 of the flow guide component 100 and the transition surface 1321 of the transition part 132 is located in the 1 / 3 area of ​​the transition surface 1321 near the weak part 133. Under the premise of ensuring the guiding function, the excessive compression of the transition surface 1321 on the cutting surface 1210 can be reduced, and the cutting part 121 can be prevented from deforming and passing over the part to be cut of the sealing film. This allows the cutting part 121 to smoothly cut the weak part 133 of the sealing film 130. In particular, when only a small part of the sealing film remains to be cut, the sealing film at that position can be cut smoothly, avoiding the sealing film failure caused by poor cutting.

[0046] Figure 6 for Figure 3A A magnified view of the cut surface and transition surface shown. (See attached image.) Figure 3A and Figure 6 As shown, in the cross-section passing through the central axis Z of the tube body 110 and the cutting section 121 and perpendicular to the sealing membrane 130, the cutting surface 1210 has a curved cutting line, which includes a first end P1 and a second end P2. The transition surface 1321 also has a curved cutting line, which includes a third end P3 and a fourth end P4. The distance between the third end P3 and the first end P1 along the reference direction X is the first distance D1, and the distance between the third end P3 and the fourth end P4 along the reference direction X is the second distance D2. The ratio of the difference between the second distance D2 and the first distance D1 to the second distance D2 is greater than 0 and less than or equal to 1 / 3. The reference direction X is parallel to the sealing membrane 130. Figure 3A and Figure 6 Within the cross-section, by ensuring that the ratio of the difference between the second spacing D2 and the first spacing D1 to the second spacing D2 is greater than 0 and less than or equal to 1 / 3, when the cutting surface 1210 abuts against the transition surface 1321, the contact area between the transition surface 1321 and the cutting surface 1210 can be reduced, thus decreasing the force exerted by the transition surface 1321 on the cutting surface 1210 and reducing the influence of the transition surface 1321 on the cutting action of the cutting part 121, thereby improving cutting efficiency and yield. For example, the aforementioned ratio is greater than or equal to 10% and less than or equal to 20%. This embodiment of the invention does not limit the specific value of the aforementioned ratio and can adjust it according to materials, structure, etc.

[0047] In some examples, such as Figures 2-4As shown, the sealing membrane 130 and the tube body 110 can be integrally formed. Integral forming improves the yield rate of the seal, simplifies the manufacturing process of the flow guiding components, and increases the integration level of the flow guiding components. The cutting ring mates with the tube body, and the sealing membrane and tube body are integrally formed, thereby ensuring the dimensional and positional relationship between the cutting ring and the sealing membrane, and ensuring effective cutting of the sealing membrane by the cutting ring. Of course, this embodiment of the invention is not limited in this respect. For example, the sealing membrane can be formed on the tube body through a post-processing technique.

[0048] In some examples, such as Figures 2-4 , Figure 6 As shown, the sealing membrane 130 also includes a thickened portion 134, which surrounds the weak portion 133 and connects the weak portion 133 and the tube body 110. In the direction parallel to the central axis Z of the tube body 110, the thickness H of the thickened portion 134 is greater than the thickness of the weak portion 133. By providing the thickened portion 134, the molding process of the flow guiding component 100 can be improved, and the product yield can be increased.

[0049] For example, when the sealing membrane 130 and the tube body 110 are integrally molded, during the injection molding process of the flow guiding component 100, if the thickness of the weak portion 133 is small and the width is large (this width is the distance between the transition portion 132 and the thickened portion 134), the weak portion 133 will affect the fluid flow. By setting the thickened portion 134, the width of the weak portion 133 can be reduced, thereby reducing the distance between the transition portion 132 and the thickened portion 134, improving the fluid flow, increasing molding efficiency, and improving yield.

[0050] In some examples, such as Figures 2-4 , Figure 6 As shown, the thickness H of the thickened portion 134 is greater than 1.2 times the thickness of the weak portion 133. For example, the thickness of the thickened portion 134 is greater than 1.5 times the thickness of the weak portion 133. This embodiment of the invention does not limit the thickness of the thickened portion 134, and it can be adjusted according to the product dimensions and process parameters.

[0051] In some examples, such as Figures 2-4 As shown, an inner guide element 112 is provided on the inner wall of the tube body 110. For example, the inner guide element 112 includes an internal thread. For example, an outer guide element 124 is provided on the outer wall of the cutting ring 120. For example, the outer guide element 124 includes an external thread. Through the interaction between the outer guide element 124 of the cutting ring 120 and the inner guide element 112 on the inner wall of the tube body 110, the cutting ring 120 can rotate about the central axis Z of the tube body 110. Thus, the cutting ring 120 can cut and flip the sealing membrane 130 during rotation.

[0052] In some examples, such as Figures 2-4 ,Figure 6 As shown, the distance D3 by which the thickened portion 134 extends from the inner wall of the tube body 110 toward the central axis Z of the tube body 110 is less than or equal to 2 / 3 of the height D4 of the inner guide element 112, i.e., the internal thread. Therefore, the thickened portion 134 can be prevented from affecting the rotation of the cutting ring 120.

[0053] In some examples, such as Figure 4 As shown, the included angle θ between the transition surface 1321 and the surface of the weak portion 133 ranges from 120 degrees to 150 degrees. On the one hand, this ensures the thickness of the transition portion 132 along the central axis Z direction of the tube body 110, improving fluid flowability during the injection molding process of the flow guide component 100. On the other hand, it facilitates the fit between the cutting surface 1210 of the cutting portion 121 and the transition surface 1321, ensuring that the contact area between the two is controlled within 1 / 3 of the area of ​​the transition surface 1321 near the weak portion 133.

[0054] Figure 7 for Figure 2 The diagram shows the open state of the sealing membrane. Figure 2 and Figure 7 As shown, the cutting ring 120 also includes a retaining portion 122, which is located on both sides of the cutting portion 121 along the circumference of the cutting ring 120, and the cutting portion 121 protrudes from the retaining portion 122 in the direction toward the sealing film 130. The retaining portion 122 is used for flipping the sealing film 130, and after the sealing film 130 is flipped, it can also play an auxiliary role in retaining the sealing film 130, keeping the sealing film 130 in the flipped state and preventing the sealing film 130 from shaking or shifting.

[0055] For example, the cutting process of the cutting part in the flow guiding component of this utility model is as follows: Figure 5A and Figure 7As shown, when the cutting ring rotates, the first cutting part 1211 cuts the sealing membrane 130 along the superior arc C1, while the second cutting part 1212 cuts the sealing membrane 130 along the inferior arc C2. When the second cutting part 1212 passes the first starting point P1 along the inferior arc C2, most of the sealing membrane 130 is disconnected from the tube body 110, and the sealing membrane 130 is in a relatively relaxed state. At this time, when the first cutting part 1211 continues to move along the superior arc C1 towards the second starting point P2, because the sealing membrane 130 is in a relatively relaxed state, it is easier for the sealing membrane 130 to flip under the action of external force than to be cut. When the transition surface 1321 guides the cutting surface 1210 of the first cutting part 1211, the transition surface 1321 of the sealing film 130 is subjected to the reaction force of the cutting surface 1210 of the first cutting part 1211. This reaction force causes the sealing film 130 to flip over. Furthermore, under the guidance of the holding part 122, the sealing film 130 is flipped over by the cutting ring 120. After the sealing film 130 flips over, it remains in the flipped state under the action of the cutting part 121 and the holding part 122 of the cutting ring 120, thus realizing the change of the pipe opening 111 of the tube body 110 from a sealed state to an open state.

[0056] In some examples, such as Figures 1-3A As shown, the cap assembly 200 includes a flow guide 100 and a cap 210. The tube body 110 also includes an opening 113 opposite to the sealing membrane 130, and the cap 210 is configured to seal the opening 113 or expose the opening 113. The cap assembly 200 has the beneficial effects corresponding to the beneficial effects of the flow guide 100, which will not be described in detail here.

[0057] In some examples, such as Figures 1-3A As shown, the cap 210 is fitted around the outer periphery of the tube body 110 and is configured to rotate relative to the tube body 110. For example, the internal thread on the inner sidewall of the cap 210 engages with the external thread on the outer sidewall of the tube body 110 to allow the cap 210 to rotate relative to the tube body 110.

[0058] Figure 8 for Figure 1 Another cross-sectional view of the cover assembly along the vertical sealing membrane is shown. (See diagram below.) Figure 8 As shown, the cap 210 includes a driving part 211, and the cutting ring 120 includes a driven part 123. The driving part 211 and the driven part 123 are configured such that when the cap 210 rotates relative to the tube body 110, the driving part 211 and the driven part 123 abut against each other, so that the rotation of the cap 210 drives the cutting ring 120 to rotate and causes the cutting ring 120 to cut the sealing film 130 around the central axis Z of the tube body 110.

[0059] For example, before the cap 210 is first opened (or loosened), the cap 210 is in the initially tightened position, and the cutting ring 120 is also in the initial position. Figure 8As shown, the cutting ring 120 is completely located inside the tube body 110, and the cutting portion 121 and the sealing membrane 130 are spaced apart, meaning they do not contact each other, and the cap 210 seals the opening 113. For example, when the cap 210 is loosened for the first time, the cap 210 is rotated about the central axis Z of the tube body 110 (for example, in...). Figure 1 (In the counter-clockwise direction) and moves away from the sealing film 130, the driving part 211 of the cap 210 abuts against the driven part 123 of the cutting ring 120, and drives the cutting ring 120 to rotate around the central axis Z of the tube body 110 (for example, in Figure 1 (The direction is counterclockwise). The aforementioned rotation of the cap 210 causes it to move away from the sealing membrane 130 and eventually detach from the tube body 110, exposing the opening 113. The aforementioned rotation of the cutting ring 120 causes it to approach the sealing membrane 130 and cut it. As the cutting ring 120 rotates, the sealing membrane 130 is partially cut and flipped. At this time, both ends of the tube body 110 of the guide component 100 are connected to the outside. The above structural arrangement allows the opening action of the cap 210 and the opening action of the sealing membrane 130 to be performed simultaneously, achieving continuity between the two actions. Moreover, it avoids the user's manual operation of opening the sealing membrane 130, improving user convenience and user experience.

[0060] This utility model embodiment also provides a packaging container. Figure 9 This is a partial structural diagram of a packaging container provided for an embodiment of the present utility model. (See diagram below.) Figure 9 As shown, the packaging container 300 includes any of the lid components 200 described above, and thus, the packaging container 300 has the beneficial effects corresponding to the beneficial effects of the lid component 200, which will not be repeated here.

[0061] In some examples, such as Figure 1 , Figure 2 , Figure 7 and Figure 9 As shown, the packaging container 300 also includes a container body 310. The cavity of the container body 310 is isolated from the outside world by the sealing membrane 130 of the flow guiding component 100, and is connected to the outside world after the sealing membrane 130 is cut open by the cutting ring 120. Thus, the sealing membrane 130 can effectively protect the items stored inside the container body 310. For example, in this invention, the items may include liquid food, thereby extending the shelf life of the liquid food. Furthermore, the design of the cutting ring 120 and the cap 210 facilitates the opening of the sealing membrane 130, improving user convenience and user experience.
