Description

Technical Field

[0001] This utility model relates to the field of packaging technology, and in particular to a connecting component and a container. Background Technology

[0002] Currently, containers that require airtight preservation (such as beverage bottles, sauce bottles, or medicine bottles) on the market typically use aluminum foil to heat-seal the container opening, thereby sealing the container. After sealing, the container lid is then put on.

[0003] However, when using the aforementioned containers, consumers need to open the container lid first and then manually tear off the aluminum foil in order to access the contents of the container, which is inconvenient for consumers. Utility Model Content

[0004] The purpose of this invention is to solve the problem of inconvenience in using current containers. This invention provides a connecting component and a container, which can effectively improve the convenience for consumers to open the container, while simplifying the production process and reducing costs.

[0005] To address the aforementioned technical problems, this utility model discloses a connecting component, comprising:

[0006] The lower connector has an opening;

[0007] An upper cover having a lower surface, the upper cover being disposed on the lower connector in a manner detachable from the lower connector;

[0008] Water-barrier and oxygen-barrier pads;

[0009] The connection component has an initial state and an open state;

[0010] In the initial state, the upper cover is placed on the lower connector, and the water-blocking and oxygen-barrier pads are fixed to the lower surface of the upper cover and the edge of the opening by melting, respectively, and sealing the opening;

[0011] In the open state, the upper cover is separated from the lower connector;

[0012] During the process of switching from the initial state to the open state, the upper cover causes the water-blocking and oxygen-barrier pad to separate from the opening.

[0013] By adopting the above technical solution, on the one hand, compared to some containers where only the water-barrier and oxygen-barrier gasket is heat-sealed to the lower connector while being fixed to the upper cap with additional fasteners, this application fixes the water-barrier and oxygen-barrier gasket to the lower surface of the upper cap and the edge of the opening by melting. This is equivalent to achieving heat sealing of the water-barrier and oxygen-barrier gasket to the lower surface of the upper cap and the edge of the opening during the cap production stage, eliminating the heat sealing process in the product manufacturing plant. Simultaneously, it also eliminates the need for additional fasteners, simplifying the process and saving costs. Furthermore, using a melting method to fix the water-barrier and oxygen-barrier gasket to the lower surface of the upper cap and the edge of the opening not only simplifies the process but also provides a more reliable fixation.

[0014] Furthermore, since water-barrier and oxygen-barrier gaskets are typically sealed directly to the bottle opening in the current market, the sealing process usually takes place at the product manufacturing plant. However, in this embodiment, both the upper cap and the lower connector are part of the bottle cap, and the water-barrier and oxygen-barrier gasket is sealed onto the lower connector. Therefore, the sealing process can be completed during the bottle cap production stage, and it will not be affected by the sealing equipment or operators of different manufacturers, thus avoiding a decrease in consistency and stability. In other words, the connecting assembly provided in this embodiment has better sealing stability.

[0015] On the other hand, in the initial state, when the consumer needs to break the seal of the water-blocking and oxygen-barrier gasket on the opening, since the water-blocking and oxygen-barrier gasket only melts with the edge of the opening and not with the entire opening, and the opposite side melts with the lower surface of the upper cover, the melting area of ​​the water-blocking and oxygen-barrier gasket and the upper cover is greater than the melting area of ​​the water-blocking and oxygen-barrier gasket and the lower connector. That is, the connection force between the water-blocking and oxygen-barrier gasket and the upper cover is greater than the connection force between the water-blocking and oxygen-barrier gasket and the lower connector.

[0016] In other words, simply opening the top cover and separating it from the lower connector allows the top cover to detach the water-blocking and oxygen-barrier gasket from the opening, thus disabling its sealing effect. Compared to existing technologies where consumers need to manually remove the water-blocking and oxygen-barrier gasket after opening the bottle cap, the connecting assembly provided in this application allows the water-blocking and oxygen-barrier gasket to be separated from the opening simply by the fixing force of the top cover during the opening process. This eliminates the need for additional operation by the consumer and effectively improves the convenience of opening the bottle.

[0017] Furthermore, in the prior art, after consumers tear open the water-blocking and oxygen-barrier pad, they still need to dispose of it as waste. However, in the embodiment of this application, since the water-blocking and oxygen-barrier pad is fixed to the lower surface of the upper cover by melting, the water-blocking and oxygen-barrier pad remains fixed to the upper cover after the consumer opens it. Therefore, the water-blocking and oxygen-barrier pad will not fall off, and there is no need to dispose of it as waste, which further improves convenience.

[0018] According to a specific embodiment of the present invention, the water-blocking and oxygen-barrier pad includes a first surface and a second surface, wherein the first surface is fixed to the lower surface of the upper cover by melting.

[0019] The second surface includes a first annular region and a sealing region. The sealing region and the first annular region are sequentially arranged in a direction extending outward from the center of the water-blocking and oxygen-barrier pad. The first annular region is fixed to the edge of the opening by melting, so that the sealing region seals the opening.

[0020] Using the above technical solution, the first annular area fits tightly against the edge of the opening, so that the sealing area covers the opening, thereby achieving a seal. In other words, the molten area between the water-blocking and oxygen-barrier gasket and the lower connector is only the first annular area, not the entire second surface, while the lower surface of the upper cover is molten with the entire first surface. Therefore, the molten area between the water-blocking and oxygen-barrier gasket and the upper cover is greater than the molten area between the water-blocking and oxygen-barrier gasket and the lower connector, meaning the bonding force between the water-blocking and oxygen-barrier gasket and the upper cover is greater than the bonding force between the water-blocking and oxygen-barrier gasket and the lower connector. In other words, simply opening the upper cover and separating it from the lower connector allows the upper cover to pull the water-blocking and oxygen-barrier gasket away from the opening, causing it to lose its sealing effect.

[0021] According to a specific embodiment of the present invention, the opening includes an edge region and a recessed region. The first annular region is fixed to the edge region of the opening by melting, so that the sealing region seals the recessed region. Along the height direction of the connecting component, the projection of the second surface minus the projection of the edge region is the projection of the recessed region.

[0022] According to a specific embodiment of the present invention, the water-blocking and oxygen-barrier pad further includes a second annular region. Along the direction extending outward from the center of the water-blocking and oxygen-barrier pad, the sealing region, the first annular region, and the second annular region are sequentially defined. Along the height direction of the connecting component, the projection of the second surface minus the projection of the opening is the projection of the second annular region.

[0023] Using the above technical solution, the projection of the second surface minus the projection of the opening equals the projection of the second annular area. This means the second annular area is neither fixed nor in contact with the opening. Furthermore, since the sealing area only serves a sealing function and does not fuse with the opening, the contact surface between the water-blocking and oxygen-barrier gasket and the upper cover (i.e., the entire first surface) is much larger than the contact surface between the water-blocking and oxygen-barrier gasket and the lower connector (i.e., the first annular area of ​​the second surface). Therefore, the connection force between the water-blocking and oxygen-barrier gasket and the upper cover is greater than the connection force between the water-blocking and oxygen-barrier gasket and the lower connector. In other words, simply opening the upper cover and separating it from the lower connector allows the upper cover to detach the water-blocking and oxygen-barrier gasket from the opening, thus eliminating its sealing effect.

[0024] According to a specific embodiment of the present invention, the area of ​​the second annular region accounts for 10% to 50% of the total area of ​​the water-blocking and oxygen-barrier pad.

[0025] By adopting the above technical solution, the area of ​​the second annular region accounts for a small proportion of the total area of ​​the water-blocking and oxygen-barrier pad. This allows for improved utilization of the water-blocking and oxygen-barrier pad while fixing it to the upper cover, thus saving on material costs.

[0026] According to a specific embodiment of the present invention, the water-blocking and oxygen-barrier pad is circular in shape.

[0027] According to a specific embodiment of the present invention, the water-blocking and oxygen-barrier gasket is a multi-layer sealing gasket containing aluminum foil.

[0028] According to a specific embodiment of the present invention, the water-blocking and oxygen-barrier pad includes a first adhesive layer, an intermediate layer, and a second adhesive layer. The material of the first adhesive layer is the same as or similar to the material of the upper cover. The first adhesive layer is fixed to the upper cover by melting. The intermediate layer is an aluminum foil layer. The material of the second adhesive layer is the same as or similar to the material of the lower connector. The second adhesive layer is fixed to the lower connector by melting.

[0029] According to a specific embodiment of this utility model, the water-blocking and oxygen-barrier pad includes a first adhesive layer, an intermediate layer, and a second adhesive layer. The material of the first adhesive layer is different from that of the upper cover. Adhesive is applied to the side of the first adhesive layer facing the upper cover, and the adhesive is fixed to the upper cover by melting. The intermediate layer is an aluminum foil layer. The material of the second adhesive layer is different from that of the lower connector. Adhesive is applied to the side of the second adhesive layer facing the lower connector, and the adhesive is fixed to the lower connector by melting.

[0030] According to a specific embodiment of the present invention, the lower connector has a top wall, and the opening is provided on the top wall.

[0031] According to a specific embodiment of the present invention, the top wall is provided with a first protrusion, which protrudes toward the upper cover body;

[0032] In the initial state, the sealing area of ​​the water-blocking and oxygen-barrier pad seals the opening of the first protrusion.

[0033] According to a specific embodiment of the present invention, the lower surface of the upper cover protrudes towards the lower connector, and the upper surface of the top wall is a plane; the second surface of the water-blocking and oxygen-barrier pad is flush with the lower surface of the protrusion.

[0034] This utility model also discloses a container, comprising:

[0035] The container body has a container opening;

[0036] The connecting component as described in any of the above specific embodiments is disposed on the container opening.

[0037] By adopting the above technical solution and incorporating the aforementioned connecting components into the container, the water-barrier and oxygen-barrier gasket can be easily separated from the opening during the process of opening the cap, eliminating the need for additional consumer intervention and effectively improving the convenience of opening the cap. Simultaneously, the water-barrier and oxygen-barrier gasket is fixed to the lower surface of the cap and the edge of the opening by a fusion process, essentially achieving heat sealing of the gasket to these surfaces during the cap manufacturing stage, thus eliminating the need for a heat-sealing process at the product manufacturing plant. Furthermore, it eliminates the need for additional fasteners, simplifying the process and saving costs. Moreover, the fusion method for fixing the water-barrier and oxygen-barrier gasket to the lower surface of the cap and the edge of the opening not only simplifies the process but also ensures a more secure fixation.

[0068] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0069] refer to Figure 1 This application discloses a container 100. The specific type of container 100 is not specifically limited in this application; for example, container 100 can be a beverage bottle, sauce bottle, or medicine bottle, etc., used to store solids or liquids. Exemplarily, this application uses a sauce bottle as an example to describe its structure in detail. Exemplarily, container 100 is a circular container (i.e., the cross-section of container 100 is circular), but it is not limited to this. In other possible embodiments, the cross-section of container 100 can also be rectangular, triangular, pentagonal, or other shapes.

[0070] In this embodiment, the container 100 is made of PET (Polyethylene terephthalate). However, it is understood that this embodiment does not impose any special limitations on the specific material of the container 100. For example, in other possible embodiments, the container 100 may also be made of PE (Polyethylene), PP (Polypropylene), glass, etc. In some other possible embodiments, the container 100 is a multilayer co-extruded bottle.

[0071] To facilitate a detailed description of the specific structure of container 100 later, the height direction Z and circumferential direction R of container 100 are defined here first. Among them, the circumferential direction R surrounds the height direction Z.

[0072] For example, refer to Figures 1 to 3 The container 100 includes a container body 101 and a connecting assembly 200. The container body 101 has a receiving cavity 102 and a container opening 103. The receiving cavity 102 is used to store sauce. The container opening 103 allows the sauce to flow out of the receiving cavity 102. The connecting assembly 200 is fitted onto the container opening 103. The connecting assembly 200 has an initial state and an open state; in the initial state, the connecting assembly 200 seals the container opening 103.

[0073] For example, the connecting component 200 is made of PP (Polypropylene). However, it is understood that the specific material of the connecting component 200 is not specifically limited in this application embodiment. For example, in other possible embodiments, the connecting component 200 may also be made of PE (Polyethylene), PET (Polyethylene terephthalate), etc. In some other possible embodiments, the connecting component 200 may also be made of other mixed materials.

[0074] Specifically, in this embodiment, the connecting component 200 includes: a lower connector 220, an upper cover 210, and a water-blocking and oxygen-barrier pad 300. The lower connector 220 covers the container opening 103, and the lower connector 220 has an opening 222 that extends through the lower connector 220 along the height direction Z, so that the sauce can flow out of the receiving cavity 102 of the container body 101 through the opening 222 for the consumer to use. For example, in conjunction with... Figure 4A The opening 222 has an edge area 2221 and a recessed area 2222. That is, the edge area 2221 is connected end to end to form the recessed area 2222. The sauce flows out of the cavity 102 of the container body 101 from the recessed area 2222 for consumers to take.

[0075] In this embodiment, the lower connector 220 covers the container opening 103 of the container body 101. That is, the lower connector 220 is a lower cover, and the connecting component 200 in this embodiment is a layered container cover.

[0076] Specifically, refer to Figure 3 The lower connector 220 is provided with an internal thread 2201, and the outer wall of the container opening 103 is provided with an external thread 104. The internal thread 2201 and the external thread 104 are threaded together so that the lower connector 220 covers the container opening 103 of the container body 101.

[0077] For example, the upper cover 210 has a lower surface 211, and the upper cover 210 is disposed on the lower connector 220 in a separable manner from the lower connector 220. When the upper cover 210 is disposed on the lower connector 220, the lower surface 211 of the upper cover faces the lower connector 220.

[0078] For example, the water-blocking and oxygen-barrier gasket 300 is fixed to the lower surface 211 of the upper cover and the edge region 2221 of the opening 222 by melting. That is, the water-blocking and oxygen-barrier gasket 300 is only melted with the edge region 2221 of the opening 222, but not with the recessed region 2222 of the opening 222, and only covers the recessed region 2222 of the opening 222 to achieve a sealing effect. The other side (i.e., the second side 302 described later) is melted with the lower surface 211 of the upper cover.

[0079] Therefore, due to the presence of the concave cavity 2222, the melting area of ​​the water-blocking and oxygen-barrier pad 300 and the upper cover 210 (i.e., Figure 4A The A1 area shown is for ease of display. Figure 4A The A1 area has been blackened (the area is larger than the melting area of ​​the water-blocking and oxygen-barrier pad 300 and the lower connector 220). Figure 4A The B1 area shown is for ease of display. Figure 4A The B1 area has been blackened, which is the first annular area 2221 described later. That is, the connection force between the water-blocking and oxygen-barrier pad 300 and the upper cover 210 is greater than the connection force between the water-blocking and oxygen-barrier pad 300 and the lower connector 220.

[0080] For example, the connection component 200 has an initial state and an open state. It should be noted that the initial state can be understood as the state of the connection component 200 when it is completed in production or shipped from the factory, or as an unopened state. The open state is the state of the connection component 200 after it has been unsealed or opened by the consumer.

[0081] In the initial state (e.g.) Figure 1 and Figure 3 As shown), the upper cover 210 covers the lower connector 220, and the water-blocking and oxygen-barrier gasket 300 seals the opening 222 of the lower connector 220. In the open state (e.g.) Figure 2 As shown, the upper cover 210 separates from the lower connector 220, and the water-blocking and oxygen-barrier pad 300 disengages from the opening 222. During the process of switching the connecting assembly 200 from the initial state to the open state, because the connecting force between the water-blocking and oxygen-barrier pad 300 and the upper cover 210 is greater than the connecting force between the water-blocking and oxygen-barrier pad 300 and the lower connector 220, the upper cover 210 causes the water-blocking and oxygen-barrier pad 300 to disengage from the opening 222.

[0082] In this embodiment, for example, the water-blocking and oxygen-barrier pad 300 is simultaneously fixed to the upper cover 210 and the lower connector 220. Specifically, in the initial state, the water-blocking and oxygen-barrier pad 300 is fixed to the lower surface 211 of the upper cover and the edge of the opening 222 by melting, thereby sealing the opening 222. After the water-blocking and oxygen-barrier pad 300 is melted with the lower connector 220, the water-blocking and oxygen-barrier pad 300 remains fixed to the lower connector 220 and seals the opening 222 without the action of external force. When the user opens the upper cover 210, because the connecting force between the water-blocking and oxygen-barrier pad 300 and the upper cover 210 is greater than the connecting force between the water-blocking and oxygen-barrier pad 300 and the lower connector 220, the upper cover 210 can exert an external force on the water-blocking and oxygen-barrier pad 300 greater than that exerted by the lower connector 220, thereby tearing the water-blocking and oxygen-barrier pad 300 from the lower connector 220 and allowing the water-blocking and oxygen-barrier pad 300 to detach from the opening 222. For example, when the user opens the upper cover 210, the force exerted by the upper cover 210 on the water-blocking and oxygen-barrier pad 300 is 6N to 20N (inclusive). However, it is not limited to this; it is acceptable as long as the water-blocking and oxygen-barrier pad 300 can be torn apart from the lower connector 220.

[0083] By adopting the above technical solution, on the one hand, compared to some containers where only the water-blocking and oxygen-barrier gasket is heat-sealed to the lower connector 220, while the upper cover 210 is fixed by another fastener, this application fixes the water-blocking and oxygen-barrier gasket 300 to the lower surface 211 and opening 222 of the upper cover by melting, which is equivalent to achieving heat sealing of the water-blocking and oxygen-barrier gasket to the lower surface of the upper cover and the edge of the opening during the bottle cap production stage. This eliminates the heat sealing process in the product manufacturing plant and also eliminates the need for additional fasteners, simplifying the process and saving costs. Furthermore, the method of fixing the water-blocking and oxygen-barrier gasket to the lower surface of the upper cover and the edge of the opening by melting not only simplifies the process but also provides a more reliable fixation.

[0084] Furthermore, since water-barrier and oxygen-barrier gaskets are typically sealed directly to the bottle opening in the current market, the sealing process usually takes place at the product manufacturing plant. However, in this embodiment, both the upper cap 210 and the lower connector 220 are part of the bottle cap, and the water-barrier and oxygen-barrier gasket 300 is sealed onto the lower connector 220. Therefore, the sealing process can be completed during the bottle cap production stage, and will not be affected by the sealing equipment or operators of different manufacturers, thus avoiding a decrease in consistency and stability. In other words, the sealing stability of the connecting component 200 provided in this embodiment is better.

[0085] On the other hand, in the initial state, when a consumer needs to take the sauce from the container 100, they only need to open the upper cover 210 to separate it from the lower connector 220. Since the connection force between the water-blocking and oxygen-barrier pad 300 and the upper cover 210 is greater than the connection force between the water-blocking and oxygen-barrier pad 300 and the lower connector 220, the upper cover 210 can drive the water-blocking and oxygen-barrier pad 300 to detach from the opening 222. Compared to sauce bottles on the market that require consumers to manually remove the aluminum foil after opening the cap, the container 100 provided in this application embodiment allows consumers to complete the action of separating the water-blocking and oxygen-barrier pad 300 from the opening 222 during the process of opening the upper cover 210, without requiring additional operation from the consumer. This eliminates the process of tearing off the water-blocking and oxygen-barrier pad after opening the cap, effectively improving the convenience of opening the cap for consumers.

[0086] Furthermore, in the current market, after consumers tear open the water-blocking and oxygen-barrier pads on sauce bottles, they still need to dispose of them as waste. However, in this embodiment, since the water-blocking and oxygen-barrier pads 300 are fixed to the lower surface 211 of the upper cover by melting, the water-blocking and oxygen-barrier pads 300 remain fixed to the upper cover 210 after the consumer opens the upper cover 210. Therefore, the water-blocking and oxygen-barrier pads 300 will not fall off, and there is no need to dispose of them as waste, further improving convenience.

[0087] For example, refer to Figure 2 The lower surface 211 of the upper cover is provided with a fixing groove 212. Exemplarily, combined with... Figures 4A to 4C The water-blocking and oxygen-barrier pad 300 includes a first surface 301 and a second surface 302. The first surface 301 is fused to the lower surface 211 of the upper cover, and the second surface 302 is fused to the edge area 2221 of the opening 222. Specifically, the first surface 301 is fused to the lower surface 2121 of the fixing groove. Along the height direction Z of the container 100, the projection of the first surface 301 is the lower surface 2121 of the fixing groove. Figure 2 The visible projection (i.e.) Figure 4A (As shown in area A1). Therefore, the area of ​​the water-blocking and oxygen-barrier pad 300 is the same as the area of ​​the fixing groove 212, which can effectively reduce the area of ​​the water-blocking and oxygen-barrier pad 300 and save the material cost of the water-blocking and oxygen-barrier pad 300.

[0088] For example, the second surface 302 includes a first annular region 3021 and a sealing region 3022. The first annular region 3021 is fixed to the edge region 2221 of the opening 222 in a molten manner, so that the sealing region 3022 seals the opening 222. Specifically, the first annular region 3021 is tightly fitted to the edge region 2221 of the opening 222, so that the sealing region 3022 covers the recessed area 2222 of the opening 222, thereby sealing the opening 222 and preventing the sauce from flowing out of the recessed area 2222.

[0089] In other words, along the height direction Z of the container 100 (that is, the height direction of the connecting component 200), the projection of the edge region 2221 of the opening 222 coincides with the projection of the first annular region 3021, and the projection of the recessed region 2222 of the opening 222 coincides with the projection of the sealing region 3022.

[0090] For example, the second surface 302 also includes a second annular region 3023 extending from the center of the second surface 302 to the outer periphery of the second surface 302 (i.e. Figure 4C (As shown in direction C), it passes sequentially through sealing area 3022, first annular area 3021 and second annular area 3023. That is, sealing area 3022 is the innermost, first annular area 3021 is in the middle, and second annular area 3023 is the outermost, and second annular area 3023 does not contact the lower connector 220.

[0091] In other words, along the height direction Z of container 100, the projection of the second surface 302 covers the projection of the opening 222, and the projected area of ​​the second surface 302 (i.e. Figure 4A The area of ​​region A1 shown is greater than the projected area of ​​opening 222. Specifically, the projection of the second surface 302 minus the projection of opening 222 equals the projection of the second annular region 3023 (i.e., Figure 4A (As shown in region B1).

[0092] It can be seen that the contact surface between the water-blocking and oxygen-barrier pad 300 and the upper cover 210 (i.e., the entire first surface 301) is much larger than the contact surface between the water-blocking and oxygen-barrier pad 300 and the lower connector 220 (i.e., the first annular area 3021 of the second surface 302). Therefore, the connection force between the water-blocking and oxygen-barrier pad 300 and the upper cover 210 is greater than the connection force between the water-blocking and oxygen-barrier pad 300 and the lower connector 220.

[0093] For example, the area of ​​the second annular region 3023 accounts for 10% to 50% (inclusive) of the total area of ​​the water-blocking and oxygen-barrier pad 300. Preferably, in this embodiment, the area of ​​the second annular region 3023 accounts for 15% of the total area of ​​the water-blocking and oxygen-barrier pad 300. This results in a relatively small proportion of the area of ​​the second annular region 3023 to the total area of ​​the water-blocking and oxygen-barrier pad 300, which improves the utilization rate of the water-blocking and oxygen-barrier pad 300 and saves on material costs while fixing the water-blocking and oxygen-barrier pad 300 to the upper cover 210.

[0094] It is understood that the embodiments of this application do not impose special restrictions on the proportion of the area of ​​the second annular region 3023 to the total area of ​​the water-blocking and oxygen-barrier pad 300. For example, in other possible embodiments, the area of ​​the second annular region 3023 may account for 10%, 20%, 30%, 35%, 40%, 46%, or 50% of the total area of ​​the water-blocking and oxygen-barrier pad 300.

[0095] In this embodiment, the water-blocking and oxygen-barrier pad 300 is circular, but it is not limited to this. In other possible embodiments, the shape of the water-blocking and oxygen-barrier pad 300 can also be a square, triangle, pentagon, or other polygon.

[0096] In the manufacturing process of the connecting assembly 200 of this application embodiment, the water-blocking and oxygen-barrier pad 300 is first placed in the fixing groove 212, and then fixed in the fixing groove 212 by melting. Finally, the upper cover 210 is placed on the lower connector 220, and the water-blocking and oxygen-barrier pad 300 is fixed to the lower connector 220 by melting. In other words, the connecting assembly 200 of this application embodiment completes the fixing of the water-blocking and oxygen-barrier pad 300 to the upper cover 210 and the lower connector 220 during the manufacturing process.

[0097] After the water-blocking and oxygen-barrier gasket 300 is fixed to the lower connector 220 by melting, the seal of the water-blocking and oxygen-barrier gasket 300 on the opening 222 can only be released by tearing the water-blocking and oxygen-barrier gasket 300 open with external force. In other words, when the consumer opens the upper cover 210, the upper cover 210 provides an external force to the water-blocking and oxygen-barrier gasket 300 to tear it open.

[0098] For example, refer to Figure 4D The water-blocking and oxygen-barrier pad 300 is a three-layer composite structure containing aluminum foil, including a first adhesive layer 310, an intermediate layer 320, and a second adhesive layer 330. However, it is not limited to this; a multi-layer structure can also be provided between the first adhesive layer 310 and the intermediate layer 320, for example, two, three, or four layers can be provided between the first adhesive layer 310 and the intermediate layer 320. Similarly, a multi-layer structure can also be provided between the second adhesive layer 330 and the intermediate layer 320, for example, two, three, or four layers can be provided between the second adhesive layer 330 and the intermediate layer 320.

[0099] Specifically, the intermediate layer is located between the first adhesive layer 310 and the second adhesive layer 330, and is bonded together. Figure 4B The first adhesive layer 310 is fixed to the upper cover 210 by melting, wherein the side facing the upper cover 210 is the first side 301 mentioned above. The second adhesive layer 330 is fixed to the lower connector 220 by melting, wherein the side facing the lower connector 220 is the second side 302 mentioned above.

[0100] For example, the material of the first adhesive layer 310 can be the same as that of the upper cover 210, such as PP (Polypropylene), or it can be similar to that of the upper cover 210, such as ABS (Acrylonitrile-butadiene-styrene), PE (Polyethylene), PET (Polyethylene terephthalate), etc. In this case, the first adhesive layer 310 can be directly fixed to the lower surface 211 of the upper cover by melting. The melting temperature is 60℃-250℃, and in this embodiment, 90℃ is used, but it can also be 60℃, 85℃, 100℃, 150℃, or 250℃, etc.

[0101] Similarly, the material of the second adhesive layer 330 can be the same as that of the lower connector 220, such as PP (Polypropylene), or it can be similar to the material of the lower connector 220, such as ABS (Acrylonitrile-butadiene-styrene), PE (Polyethylene), PET (Polyethylene terephthalate), etc. In this case, the second adhesive layer 330 can be directly fixed to the edge area 2221 of the lower connector 220 by melting. The melting temperature is 60℃-250℃. In this embodiment, for example, 90℃ is used, but it can also be 60℃, 85℃, 100℃, 150℃, or 250℃, etc.

[0102] For example, the material of the first adhesive layer 310 may be different from that of the upper cover 210, such as PC (Polycarbonate). In this case, adhesive is provided between the first adhesive layer 310 and the lower surface 211 of the upper cover (that is, adhesive is provided on the first surface 301). The adhesive is fixed to the lower surface 211 of the upper cover by melting. Specifically, the adhesive is fixed to the lower surface 211 of the upper cover after being heated and melted. The heating temperature of the adhesive is 60℃-250℃. In this embodiment, for example, 90℃ is used, but it can also be 60℃, 85℃, 100℃, 150℃, or 250℃, etc.

[0103] Similarly, the second adhesive layer 330 may be made of a different material than the lower connector 220, for example, it may be made of PC (Polycarbonate). Adhesive is applied between the second adhesive layer 330 and the edge area 2221 of the lower connector 220 (i.e., adhesive is applied to the second surface 302). The adhesive is fixed to the edge area 2221 of the lower connector 220 by melting. Specifically, the adhesive is heated and melted before being fixed to the edge area 2221 of the lower connector 220. The adhesive heating temperature is 60℃-250℃; in this embodiment, 90℃ is used, but it can also be 60℃, 85℃, 100℃, 150℃, or 250℃, etc.

[0104] The middle layer is an aluminum foil layer with a thickness of approximately 10μm to 200μm (inclusive), which can be adjusted according to the needs of the production process. As the core barrier layer, the aluminum foil layer reflects over 90% of infrared radiation and blocks oxygen, moisture, and light, preventing oxidation or moisture absorption of the contents of the container. The hot melt adhesive layer is used for heat sealing with the opening 222 after heating. Functional layers can be selected as needed, such as one or more combinations of polymer layers, foam material layers, and self-adhesive silicone layers. The water- and oxygen-barrier gasket 300 is low-cost, readily available, and economically viable.

[0105] Furthermore, the water-barrier and oxygen-barrier pad 300 has good barrier properties, capable of blocking oxygen and moisture in the air to a certain extent, thereby reducing the amount of oxygen and moisture entering the receiving cavity 102 of the container 100. For example, the water vapor transmission rate of the water-barrier and oxygen-barrier pad 300 is less than 0.1 g / m³. 2 • Oxygen permeability less than 0.1 cm over 24 hours 3 / (m 2 ·24h·0.1MPa).

[0106] Because the water-barrier and oxygen-barrier pad 300 has good water-barrier and oxygen-barrier properties, using the water-barrier and oxygen-barrier pad 300 as the water-barrier and oxygen-barrier pad 300 can reduce the dosage of preservatives added to the items in the container 100, which is beneficial to improving food safety.

[0107] It is understandable that the intermediate layer can also be made of other materials, such as PVDC (Polyvinylidene chloride[2], EVOH (ethylene vinyl alcohol copolymer), etc. As long as it has good barrier properties, it can block oxygen and moisture in the air to a certain extent, thereby reducing the oxygen and moisture entering the containment cavity 102 of the container 100.

[0108] It is understood that in some other embodiments, the upper cover 210 may not have a fixing groove 212. In this case, the first surface 301 of the water-blocking and oxygen-barrier pad 300 is in partial contact with the lower surface 211 of the upper cover 210. This embodiment does not limit the contact area between the first surface 301 of the water-blocking and oxygen-barrier pad 300 and the lower surface 211 of the upper cover 210, as long as it can be tightly fixed to the lower surface 211 of the upper cover 210 and simultaneously fixed to the edge area 2221 of the opening 222 by melting. This can be as follows: Figure 4A The A1 area shown can also cover the entire lower surface 211 of the upper cover 210.

[0109] Continue to refer to Figures 1 to 3 In this embodiment of the application, the lower connector 220 has a top wall 221 and an opening 222 is provided on the top wall 221.

[0110] Specifically, the top wall 221 of the lower connector 220 is provided with a first protrusion 223. When the upper cover 210 is placed on the lower connector 220, the first protrusion 223 protrudes towards the upper cover 210. Exemplarily, an opening 222 is provided on the first protrusion 223, and the opening 222 extends through the first protrusion 223 along the height direction Z. Exemplarily, in this embodiment, in the initial state, the first annular region 3021 of the water-blocking and oxygen-barrier pad 300 is fused to the first protrusion 223, sealing the opening 222.

[0111] For example, when the upper cover 210 is placed on the lower connector 220, the first protrusion 223 extends into the fixing groove 212, and the first protrusion 223 is press-fitted with the inner wall of the fixing groove 212 to snap the upper cover 210 onto the lower connector 220. At the same time, the press-fit between the first protrusion 223 and the fixing groove 212 further improves the sealing effect on the opening 222.

[0112] Understandably, once the consumer tears open the water-blocking and oxygen-barrier pad 300 through the top cover 210 for the first time, the sealing effect of the water-blocking and oxygen-barrier pad 300 on the opening 222 is no longer present. However, due to the interference fit between the first protrusion 223 and the fixing groove 212, the opening 222 can be sealed a second time, allowing the contents of the container 100 to continue to be stored for a period of time.

[0113] In some possible implementations, refer to Figures 5 to 6B The top wall 221 of the lower connector 220 does not have a first protrusion; that is, the upper surface of the top wall 221 of the lower connector 220 is a plane. Correspondingly, the lower surface 211 of the upper cover protrudes towards the top wall 221 of the lower connector 220 to form a fixing groove 212.

[0114] Correspondingly, a fixing groove 212 is provided on the lower surface of the upper cover 210, and the first surface 301 of the water-blocking and oxygen-barrier pad 300 is fixed in the fixing groove 212 by melting. Furthermore, the second surface 302 of the water-blocking and oxygen-barrier pad 300 is flush with the raised lower surface (i.e., the thickness of the water-blocking and oxygen-barrier pad 300 and the depth of the fixing groove 212 are both...). Figure 6A As shown in H), in the initial state, the water-blocking and oxygen-barrier pad 300 can contact the upper surface of the top wall 221, and the water-blocking and oxygen-barrier pad 300 can be fixed to the upper surface of the top wall 221 by melting, thereby sealing the opening 222. In other words, the side of the upper cover 210 facing the lower connector 220 (that is, the lower surface 211 of the upper cover) is recessed inward in a direction away from the lower connector 220 to form the aforementioned fixing groove 212. The water-blocking and oxygen-barrier pad 300 is placed in the fixing groove 212, and the depth of the fixing groove 212 is the same as the thickness of the water-blocking and oxygen-barrier pad 300.

[0115] Of course, it is understandable that in some other embodiments, the upper cover 210 may not have a fixing groove 212. In this case, the first surface 301 of the water-blocking and oxygen-barrier pad 300 is in partial contact with the lower surface 211 of the upper cover 210. In this embodiment, the contact area between the first surface 301 of the water-blocking and oxygen-barrier pad 300 and the lower surface 211 of the upper cover 210 is not limited. As long as it can be tightly fixed to the lower surface 211 of the upper cover 210 and can be fixed to the edge area 2221 of the opening 222 by melting, it can also cover the entire lower surface 211 of the upper cover 210.

[0116] For example, at this time, the opening 222 has an edge area 2221 and a recessed area 2222. That is, the edge area 2221 is connected end to end to form the recessed area 2222. The sauce flows out of the receiving cavity 102 of the container body 101 from the recessed area 2222 for the consumer to take.

[0117] For example, the second surface 302 of the water-blocking and oxygen-barrier pad 300 includes a first annular region 3021 and a sealing region 3022. The first annular region 3021 is fixed to the edge region 2221 of the opening 222 in a molten manner, so that the sealing region 3022 seals the opening 222. Specifically, the first annular region 3021 is tightly fitted to the edge region 2221 of the opening 222, so that the sealing region 3022 covers the recessed area 2222 of the opening 222, thereby sealing the opening 222 and preventing sauce from flowing out of the recessed area 2222.

[0118] In other words, along the height direction Z of container 100 (i.e., the height direction of connecting component 200), the projection of the edge region 2221 of opening 222 (i.e., Figure 5The projection of region B2 shown coincides with the projection of the first annular region 3021, and the projection of the recessed area 2222 of the opening 222 coincides with the projection of the sealing area 3022.

[0119] Exemplarily, extending from the center of the second surface 302 to the outer periphery of the second surface 302 (i.e. Figure 6B (As shown in direction C), it passes through the sealing area 3022 and the first annular area 3021 in sequence. That is, the sealing area 3022 is the innermost part, and the first annular area 3021 is the outermost part.

[0120] In other words, along the height direction Z of container 100, the projection of the second surface 302 coincides with the projection of the opening 222. Specifically, the projection of the second surface 302 minus the projection of the edge region 2221 equals the projection of the recessed region 2222, that is, the projection of the opening 222 is the projection of the second surface 302.

[0121] Since the sealing area 3022 of the second surface 302 only contacts the recessed area 2222 of the opening 222 and does not melt, it plays a sealing role. In other words, the contact surface between the water-blocking and oxygen-barrier gasket 300 and the upper cover 210 (i.e., the entire first surface 301) is larger than the contact surface between the water-blocking and oxygen-barrier gasket 300 and the lower connector 220 (i.e., the first annular area 3021 of the second surface 302). Therefore, the connection force between the water-blocking and oxygen-barrier gasket 300 and the upper cover 210 is greater than the connection force between the water-blocking and oxygen-barrier gasket 300 and the lower connector 220.

[0122] By adopting the above solution, a top wall 221 is provided on the lower connector 220, and the opening 222 is provided on the top wall 221. This makes the area of ​​the opening 222 smaller than the area of ​​the container opening 103. Therefore, the water-blocking and oxygen-barrier gasket 300 only needs to cover the opening 222 to achieve a seal on the container opening 103, reducing the area of ​​the water-blocking and oxygen-barrier gasket 300 required and saving material costs. Furthermore, since the area of ​​the opening 222 is smaller than the container opening 103, the seal of the water-blocking and oxygen-barrier gasket 300 on the opening 222 is more stable. This application embodiment does not impose special restrictions on the covering method of the upper cover 210 and the lower connector 220.

[0123] For example, in some possible implementations, refer to Figure 7 and Figure 8 The upper cover 210 is attached to the lower connector 220 via a snap-fit ​​mechanism. Specifically, the inner wall 213 of the upper cover 210 has a first snap-fit ​​2131. The top wall 221 of the lower connector 220 has a connecting wall 224, which extends along the circumferential direction R of the upper cover 210 (i.e., the circumferential direction of the container 100). The outer surface of the connecting wall 224 has a second snap-fit ​​2241. The first snap-fit ​​2131 engages with the second snap-fit ​​2241 to secure the upper cover 210 to the lower connector 220.

[0124] For example, in some other possible implementations, refer to Figure 9 and Figure 10 The upper cover 210 is threaded onto the lower connector 220. Specifically, the inner wall 213 of the upper cover 210 has an internal thread 2132. The top wall 221 of the lower connector 220 has a connecting wall 224, which extends along the circumferential direction R of the upper cover 210 (i.e., the circumferential direction of the container 100). The outer surface of the connecting wall 224 has a first external thread 2242. The internal thread 2132 and the first external thread 2242 are threaded together to secure the upper cover 210 onto the lower connector 220.

[0125] Using the above technical solution, the upper cover 210 and the lower connector 220 are connected by threads. When the consumer opens the upper cover 210, the upper cover 210 needs to be screwed on. This causes the upper cover 210 to drive the water-blocking and oxygen-barrier pad 300 to generate a circumferential rotational force R, thereby breaking the weld between the water-blocking and oxygen-barrier pad 300 and the lower connector 220, so that the water-blocking and oxygen-barrier pad 300 is separated from the opening 222.

[0126] For example, refer to Figure 2 and Figure 3 In some possible implementations, the container 100 of this application embodiment also includes a lid connecting part 201, one end of which is fixed to the upper cover body 210 and the other end is fixed to the lower connector 220. That is to say, the connecting component 200 of this application embodiment is a flip cover.

[0127] It should be noted that when the container 100 is provided with the lid connecting part 201, after the consumer opens the upper lid 210, the upper lid 210 is connected to the lower connector 220 through the lid connecting part 201. However, at this time, the upper lid 210 and the lower connector 220 are still in a separate state, that is, the upper lid 210 is not covered by the lower connector 220.

[0128] For example, in some other possible implementations, no cover connection is provided, that is, the upper cover 210 and the lower connector 220 are two independent components.

[0129] refer to Figures 1 to 3A silicone valve 230 is provided inside the opening 222 to control the flow rate of the sauce. For example, when the container 100 is normally inverted, the sauce in the receiving cavity 102 cannot be poured out due to the presence of the silicone valve 230, effectively preventing sauce leakage. When a consumer needs to take the sauce, they can squeeze the container body 101 to increase the pressure inside the receiving cavity 102, thereby allowing the sauce to flow out of the opening 222 through the silicone valve 230. Exemplarily, along the height direction Z, the water-blocking and oxygen-barrier gasket 300 is located above the silicone valve 230. In the initial state, because the water-blocking and oxygen-barrier gasket 300 seals the opening 222, the sauce cannot flow out of the opening 222 through the silicone valve 230. When the consumer opens the upper cover 210, thereby separating the seal from the opening 222, the sauce can flow out of the opening 222 through the silicone valve 230.

[0130] For example, combined Figure 4B The silicone valve 230 is confined within the opening 222 by a limiting member 231. Specifically, the limiting member 231 is an annular component with a limiting groove 2311 at its upper end and a first abutment portion 2312 on its outer side. Correspondingly, the outer edge of the silicone valve 230 has a limiting portion 2301. The inner wall of the opening 222 has a second abutment portion 232. The second abutment portion 232 abuts against the first abutment portion 2312 to confine the limiting member 231 within the opening 222. Along the height direction Z, the limiting portion 2301 is located between the limiting member 231 and the top wall 221, and the limiting portion 2301 is accommodated within the limiting groove 2311, thereby confining the silicone valve 230 within the opening 222.

[0131] The embodiments of this application do not impose special restrictions on the specific manner in which the silicone valve 230 is disposed within the opening 222. For example, in some possible implementations, the silicone valve 230 may also be disposed within the opening 222 by means of bonding or other methods.

[0132] refer to Figure 11 and Figure 12 In another possible implementation, the lower connector 220 is part of the container body 101. Specifically, the lower connector 220 is the sidewall of the container opening 103, that is, in this embodiment, the container opening 103 is a sidewall. In other words, in this embodiment, the upper cover 210 directly covers the container opening 103.

[0133] The specific manner in which the upper cover 210 is placed over the container opening 103 can be understood by referring to the previous section on the manner in which the upper cover 210 is placed over the lower connector 220. Correspondingly, the specific manner in which the water-barrier and oxygen-barrier pad 300 is fixed to the upper cover 210 can be understood by referring to the previous section on the specific manner in which the water-barrier and oxygen-barrier pad 300 is fixed to the upper cover 210.

[0134] For example, refer to Figure 12 In some possible implementations, the inner sidewall 213 of the upper cover 210 is provided with a first buckle 2131, and the outer wall of the lower connector 220 is provided with a third buckle 225. The first buckle 2131 and the third buckle 225 are engaged so that the upper cover 210 covers the lower connector 220.

[0135] For example, refer to Figure 13 In some other possible embodiments, the inner sidewall 213 of the upper cover 210 is provided with an internal thread 2132, and the outer wall of the lower connector 220 is provided with a second external thread 226. The internal thread 2132 and the second external thread 226 are threadedly engaged to cover the lower connector 220 with the upper cover 210.

[0136] Thus, this application describes a connecting component and a container. This application fixes water- and oxygen-barrier pads to the upper cover and the lower connector by melting, so that when the consumer opens the upper cover, the upper cover can drive the water- and oxygen-barrier pads to separate from the opening, so that the consumer can easily take out the items in the container, effectively improving the convenience of opening the lid for the consumer.

[0137] Although the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the present invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
