Description

Technical Field

[0001] This invention relates to the field of packaging container technology, and in particular to a container encapsulation structure. Background Technology

[0002] High-pressure carbonated drinks and high-pressure sparkling wines refer to beverages or alcoholic drinks that contain gases such as CO2, such as Coca-Cola and champagne.

[0003] Currently, the cap assemblies used for sealing high-pressure soft drink or high-pressure spirits containers on the market typically use conventional cap assemblies. For example, the cap assemblies are connected to the container opening using snap-fit ​​or other connection methods. Because the beverage or alcohol contained in the container cavity contains gases such as CO2, the cap assembly is prone to separating from or loosening from the container opening under the action of these gases, which can easily lead to poor sealing. In addition, when the cap assembly is operated to open the container opening, the gas inside the container cavity will quickly accumulate and be released outward, causing the cap assembly to burst open due to the action of the gas. This can result in the cap assembly splashing and colliding with foreign objects or consumers, posing a problem of low safety in use.

[0004] In addition, if the cap assembly used to cover and seal high-pressure soda or high-pressure liquor containers is a cap assembly with a more complex structure, there will be problems of high manufacturing cost and inconvenience in use.

[0005] Therefore, this invention addresses the aforementioned problems. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a container packaging structure that can improve the problems existing in the prior art. By providing a first locking strip on the top cover for engaging with a first or second snap fastener, the top cover can be prevented from bursting open due to the gas inside the container body during the process of flipping and opening the container body, thus avoiding the top cover separating from the container body opening and splashing out, which could collide with foreign objects or consumers, ensuring safety. Alternatively, by providing a first locking strip and a second locking strip on the top cover for engaging with the first and second snap fasteners respectively, and by separating the first locking strip from the first snap fastener first and then the second locking strip from the second snap fastener during the top cover flipping process, a step-by-step separation can be achieved, making it convenient for the user to operate the top cover to flip and open the container body opening. It has the characteristics of being safe, reliable, easy to use, and labor-saving.

[0007] This invention is achieved through the following technical solution: This invention provides a container packaging structure, including a container body 1 with an opening, a cover seat 2 connected to the opening of the container body 1, and an upper cover 3 rotatably connected to the cover seat 2 for closing or opening the opening of the container body 1. A snap-fit ​​structure 4 is provided between the upper cover 3 and the container body 1 or the cover seat 2. The snap-fit ​​structure 4 includes at least a first snap 41 and a second snap 42 disposed at an upper-lower interval on the outer wall of the opening of the container body 1 or the cover seat 2. The snap-fit ​​structure 4 also includes at least a first locking strip segment 43 disposed on the upper cover 3 for engaging with the first snap 41 or the second snap 42. When the opening of the container body 1 is closed and sealed by the upper cover 3, the first locking strip segment 43 engages with the first snap 41. When the opening of the container body 1 is partially opened, the upper cover 3 flips relative to the cover seat 2 so that the first locking strip segment 43 separates from the first snap 41 and engages with the second snap 42.

[0008] As described above, in the encapsulation structure of a container, the upper cover 3 includes a cover body 31 for rotatably connecting with a cover base 2 and a cover side portion 32 provided on the side wall of the cover body 31, wherein the first locking strip segment 43 is provided on the inner wall of the cover body 31 and / or the cover side portion 32.

[0009] As described above, in the encapsulation structure of a container, the lid side 32 is provided with an opening lever 321 for assisting the lid side 32 to rotate relative to the lid body 31.

[0010] As described above, in the encapsulation structure of a container, the cover 31 is provided with an opening pressure plate 311 on the side away from the opening lever 321 to assist the upper cover 3 in flipping relative to the cover seat 2.

[0011] In the container encapsulation structure described above, the two sides of the lid side portion 32 are destructibly connected to the inner wall of the side wall notch 310 of the lid body 31.

[0012] In the container encapsulation structure described above, the lower port of the upper cover 3 and the upper port of the cover base 2 are malfunctionably connected.

[0013] As described above, in the encapsulation structure of a container, at least one end of the first clip segment 43 is provided with a first guide slope 431 for guiding and engaging with the first snap 41 or the second snap 42.

[0014] The present invention also provides a container packaging structure, including a container body 1 having an opening, a cover seat 2 connected to the opening of the container body 1, and an upper cover 3 rotatably connected to the cover seat 2 for closing or opening the opening of the container body 1. A snap-fit ​​structure 4 is provided between the upper cover 3 and the container body 1 or the cover seat 2. The snap-fit ​​structure 4 includes at least a first buckle 41 and a second buckle 42 disposed at an upper-lower interval on the outer wall of the opening of the container body 1 or the cover seat 2. The snap-fit ​​structure 4 also includes at least a first buckle 41 and a second buckle 42 disposed on the upper cover 3 respectively for… The first locking strip segment 43 and the second locking strip segment 44 are engaged with the first buckle 41 and the second buckle 42, respectively. When the opening of the container body 1 is closed and sealed by the upper cover 3, the first locking strip segment 43 is engaged with the first buckle 41, and the second locking strip segment 44 is engaged with the second buckle 42. When the opening of the container body 1 is partially opened, the upper cover 3 flips relative to the cover seat 2, causing the first locking strip segment 43 to separate from the first buckle 41, while the second locking strip segment 44 remains engaged with the second buckle 42.

[0015] In the container packaging structure described above, when the upper cover 3 is flipped relative to the cover seat 2 so that the first locking strip 43 separates from the first buckle 41, an clearance gap is formed between the second locking strip 44 and the second buckle 42.

[0016] As described above, in the encapsulation structure of a container, the upper cover 3 includes a cover body 31 for rotatably connecting with a cover base 2 and a cover side portion 32 provided on the side wall of the cover body 31, wherein the first locking strip segment 43 and the second locking strip segment 44 are provided on the inner wall of the cover body 31 and / or the cover side portion 32.

[0017] As described above, in the encapsulation structure of a container, the lid side 32 is provided with an opening lever 321 for assisting the lid side 32 to rotate relative to the lid body 31.

[0018] As described above, in the encapsulation structure of a container, the cover 31 is provided with an opening pressure plate 311 on the side away from the opening lever 321 to assist the upper cover 3 in flipping relative to the cover seat 2.

[0019] As described above, in the encapsulation structure of a container, the cover 2 is provided with a positioning groove 21 for the cover side 32 to be engaged and positioned when the upper cover 3 is flipped to cover the opening of the container body 1.

[0020] In the container packaging structure described above, a limiting structure 5 is provided between the positioning groove 21 and the lid side 32.

[0021] As described above, the container packaging structure includes a limiting structure 5 comprising a limiting protrusion 51 on the inner wall of the positioning groove 21 and a limiting recess 52 on the side wall of the cap side portion 32 for limiting engagement with the limiting protrusion 51.

[0022] In the container packaging structure described above, a tearable tear strip is provided between the lower port of the upper cover 3 and the upper port of the cover seat 2.

[0023] As described above, in the encapsulation structure of a container, at least one end of the first clip segment 43 is provided with a first guide slope 431 for guiding and engaging with the first buckle 41, and at least one end of the second clip segment 44 is provided with a second guide slope 441 for guiding and engaging with the second buckle 42.

[0024] Compared with the prior art, the present invention has the following advantages: 1. This invention provides a first locking strip on the top cover for engaging with a first or second snap fastener. When the first locking strip engages with the first snap fastener, the top cover stably and securely seals the opening of the container body. When the top cover is flipped relative to the cover seat to separate the first locking strip from the first snap fastener and engage with the second snap fastener, the opening of the container body is partially opened, allowing gas inside the container body to flow out. At this moment, the engagement of the first locking strip with the second snap fastener ensures a secure connection between the top cover and the container body, preventing the top cover from bursting open due to gas pressure, thus avoiding the top cover separating from the container body opening and splashing out, potentially colliding with external objects or consumers, and ensuring safe use.

[0025] 2. For ease of use, an opening lever is provided on the side of the cover to assist in rotating the side of the cover relative to the cover body. 3. At least one end of the first locking strip segment is provided with a first guide slope for guiding and engaging with the first buckle or the second buckle. In this invention, both ends of the first locking strip segment are provided with first guide slopes. When the upper cover is flipped relative to the cover seat to open the container body opening, the first guide slope on one end of the first locking strip segment guides and engages with the first buckle and the second buckle to facilitate the separation of the first locking strip segment from the first buckle or the second buckle, thereby avoiding the phenomenon of the first locking strip segment being stuck with the first buckle or the second buckle, which would affect the flipping of the upper cover. When the upper cover is flipped relative to the cover seat to close the container body opening, the first guide slope on the other end of the first locking strip segment guides and engages with the first buckle and the second buckle to facilitate the engagement of the first locking strip segment with the first buckle or the second buckle. Therefore, the above-mentioned guide structure facilitates the flipping of the upper cover relative to the cover seat to open or close the container body opening, which is a reasonable design.

[0026] 4. This invention provides a first and a second locking strip on the top cover for engaging with the first and second latches, respectively. When the first locking strip engages with the first latch and the second locking strip engages with the second latch, the top cover stably and securely seals the opening of the container body. When the top cover is flipped relative to the cover seat, separating the first locking strip from the first latch while the second locking strip remains engaged with the second latch, the opening of the container body is partially opened, allowing gas inside the container to flow out. At this point, because the second locking strip remains engaged with the second latch, the opening remains open. This design ensures a secure connection between the lid and the container body, preventing the lid from bursting open due to gas pressure and causing the lid to detach from the container opening and splash, potentially colliding with foreign objects or consumers, thus ensuring safety. The lid is then flipped relative to the lid base until the container opening is opened. During this flipping process, the second locking strip separates from the second latch. Therefore, this invention achieves step-by-step separation by first separating the first locking strip from the first latch and then separating the second locking strip from the second latch during the lid flipping process. This allows for convenient and labor-saving operation of the lid flipping mechanism to open the container opening. Attached Figure Description

Detailed Implementation

[0028] The following is in conjunction with the appendix Figure 1-12 The embodiments of the present invention will be described in detail.

[0029] like Figure 1-9 As shown, the present invention discloses a container packaging structure, comprising a container body 1 having an opening, a cover seat 2 connected to the opening of the container body 1, and an upper cover 3 rotatably connected to the cover seat 2 for closing or opening the opening of the container body 1. A snap-fit ​​structure 4 is provided between the upper cover 3 and the container body 1 or the cover seat 2. The snap-fit ​​structure 4 includes at least a first snap 41 and a second snap 42 disposed at an upper-lower interval on the outer wall of the opening of the container body 1 or the cover seat 2. The snap-fit ​​structure 4 also includes at least a first locking strip segment 43 disposed on the upper cover 3 for engaging with the first snap 41 or the second snap 42. When the opening of the container body 1 is closed and sealed by the upper cover 3, the first locking strip segment 43 engages with the first snap 41. When the opening of the container body 1 is partially opened, the upper cover 3 flips relative to the cover seat 2 so that the first locking strip segment 43 separates from the first snap 41 and engages with the second snap 42. This invention features a first locking strip on the top cover for engaging with either a first or second latch. When the first locking strip engages with the first latch, the top cover securely and stably seals the opening of the container body. When the top cover is flipped relative to the cover base, causing the first locking strip to separate from the first latch and engage with the second latch, the opening of the container body is partially opened, allowing gas inside the container to flow out. The engagement of the first locking strip with the second latch ensures a secure connection between the top cover and the container body, preventing the top cover from bursting open due to gas pressure and potentially scattering and colliding with objects or consumers, thus ensuring safety during use.

[0030] like Figure 1-9 As shown, the upper cover 3 includes a cover body 31 for rotatable connection with the cover base 2 and a cover side portion 32 provided on the side wall of the cover body 31, and the first retaining strip segment 43 is provided on the inner wall of the cover body 31 and / or the cover side portion 32. Figure 2 , 3 It can be seen that both the inner walls of the lid 31 and the lid side 32 are provided with first retaining strips 43. When it is necessary to operate the lid to flip open the container body opening, the user operates the lid side 32 to rotate outward relative to the lid 31, so that the lid side 32 is tilted relative to the container body opening, such as... Figure 5As shown, the upper cover is then flipped upwards relative to the cover seat, causing the first locking strip 43 to separate from the first latch 31 and engage with the second latch 32. At this moment, the opening of the container body is partially opened. The upper cover is then flipped upwards again relative to the cover seat until the opening of the container body is fully opened, thus separating the first locking strip 43 from the second latch 32. In this invention, the cover side 32 can also be rotated outwards or inwards relative to the cover body 31 to reset, causing the first locking strip 43 to separate from or engage with the first latch 31 and the second latch 32 accordingly.

[0031] like Figure 1-9 As shown, in order to make operation more convenient and labor-saving, the cover side 32 is provided with an opening wrench 321 for assisting the cover side 32 to rotate relative to the cover body 31.

[0032] like Figure 1-9 As shown, in order to make operation more convenient and labor-saving, the cover 31 is provided with an opening pressure plate 311 on the side away from the opening wrench 321 to assist the upper cover 3 in flipping relative to the cover seat 2.

[0033] like Figure 1-9 As shown, to achieve the anti-counterfeiting function, the two sides of the cover side portion 32 are detachably connected to the inner wall of the side wall notch 310 of the cover body 31. A tearable strip may also be provided between the two sides of the cover side portion 32 and the inner wall of the side wall notch 310 of the cover body 31.

[0034] like Figure 1-9 As shown, to achieve the anti-counterfeiting function, the lower port of the upper cover 3 and the upper port of the cover base 2 are tamper-proofly connected. A tear-resistant strip may also be provided between the lower port of the upper cover 3 and the upper port of the cover base 2.

[0035] like Figure 1-9 As shown, at least one end of the first latch segment 43 is provided with a first guide slope 431 for guiding and engaging with the first buckle 41 or the second buckle 42. In this invention, both ends of the first latch segment are provided with first guide slopes. When the upper cover is flipped relative to the cover seat to open the container body opening, the first guide slope on one end of the first latch segment guides and engages with the first buckle and the second buckle to facilitate the separation of the first latch segment from the first buckle or the second buckle, thereby avoiding the phenomenon of the first latch segment getting stuck with the first buckle or the second buckle and affecting the flipping of the upper cover. When the upper cover is flipped relative to the cover seat to close the container body opening, the first guide slope on the other end of the first latch segment guides and engages with the first buckle and the second buckle to facilitate the engagement of the first latch segment with the first buckle or the second buckle. Therefore, the above-mentioned guide structure facilitates the flipping of the upper cover relative to the cover seat to open or close the container body opening, and the design is reasonable.

[0036] To improve sealing, the inner bottom of the upper cover 3 is provided with an upper cover sealing plug for fastening into the opening of the container body 1.

[0037] like Figure 1-8 As shown in Figures 10-12, the present invention also provides a container packaging structure, including a container body 1 with an opening, a cover seat 2 connected to the opening of the container body 1, and an upper cover 3 rotatably connected to the cover seat 2 for closing or opening the opening of the container body 1. A snap-fit ​​structure 4 is provided between the upper cover 3 and the container body 1 or the cover seat 2. The snap-fit ​​structure 4 includes at least a first buckle 41 and a second buckle 42 disposed at an upper-lower interval on the outer wall of the opening of the container body 1 or the cover seat 2. The snap-fit ​​structure 4 also includes at least a buckle on the upper cover. The upper cover 3 has a first locking strip 43 and a second locking strip 44 respectively for engaging with the first buckle 41 and the second buckle 42; when the opening of the container body 1 is closed and sealed by the upper cover 3, the first locking strip 43 engages with the first buckle 41, and the second locking strip 44 engages with the second buckle 42; when the opening of the container body 1 is partially opened, the upper cover 3 flips relative to the cover seat 2, causing the first locking strip 43 to separate from the first buckle 41, while the second locking strip 44 remains engaged with the second buckle 42. This invention features a first and second locking strip segment on the top cover, respectively designed for engaging with a first and a second latch. When the first locking strip segment engages with the first latch, and the second locking strip segment engages with the second latch, the top cover stably and securely seals the opening of the container body. When the top cover is flipped relative to the cover seat, separating the first locking strip segment from the first latch while the second locking strip segment remains engaged with the second latch, the opening of the container body is partially opened. This allows gas inside the container to flow out. At this point, because the second locking strip segment remains engaged with the second latch, the opening remains open. This design ensures a secure connection between the lid and the container body, preventing the lid from bursting open due to gas pressure and causing the lid to detach from the container opening and splash, potentially colliding with external objects or consumers, thus ensuring safety. The lid is then flipped relative to the lid base until the container opening is opened. During this flipping process, the second locking strip separates from the second latch. Therefore, this invention achieves step-by-step separation by first separating the first locking strip from the first latch and then separating the second locking strip from the second latch, making it convenient for the user to flip the lid to open the container opening. This method is convenient and effortless.

[0038] Furthermore, when the upper cover 3 flips relative to the cover base 2, causing the first locking strip segment 43 to separate from the first buckle 41, a clearance gap is formed between the second locking strip segment 44 and the second buckle 42. This clearance gap facilitates the separation of the second locking strip segment 44 from the second buckle 42 during the process of opening the container opening by flipping the upper cover.

[0039] like Figure 1-8As shown in Figures 10-12, the upper cover 3 includes a cover body 31 for rotatable connection with the cover base 2 and a cover side portion 32 provided on the side wall of the cover body 31. The first locking strip segment 43 and the second locking strip segment 44 are provided on the inner wall of the cover body 31 and / or the cover side portion 32. In this invention, both the inner wall of the cover body 31 and the cover side portion 32 are provided with the first locking strip segment 43 and the second locking strip segment 44.

[0040] like Figure 10-12 As shown, the cover 2 is provided with a positioning groove 21 for the cover side 32 to be engaged and positioned when the upper cover 3 is flipped to close the opening of the container body 1. When the upper cover is flipped to close the opening of the container body, the cover side 31 is engaged and positioned in the positioning groove 21, so that the upper cover can accurately and stably close and seal the opening of the container body, avoiding the upper cover from shifting or misaligning and affecting the sealing effect.

[0041] like Figure 11 , 12 As shown, a limiting structure 5 is provided between the positioning groove 21 and the cover side 32, which makes the connection between the upper cover and the base more secure and avoids the situation where the upper cover flips relative to the cover base to open the mouth of the container body during storage, transportation and other processes.

[0042] like Figure 11 , 12 As shown, the limiting structure 5 includes a limiting protrusion 51 on the inner wall of the positioning groove 21 and a limiting recess 52 on the side wall of the cover side 32 for limiting engagement with the limiting protrusion 51. In use, the user simply pries the cover side 32 outward relative to the cover body 31, separating the limiting recess 52 from the limiting protrusion 51, making the operation convenient.

[0043] like Figure 1-8 As shown in Figures 10-12, to prevent counterfeiting, a tear-resistant strip is provided between the lower port of the upper cover 3 and the upper port of the cover base 2. Before flipping the upper cover, the tear strip needs to be torn, thereby destroying the integrity of the packaging structure and achieving the anti-counterfeiting effect.

[0044] like Figure 1-8 As shown in Figures 10-12, for ease of use, the first clip segment 43 has at least one end provided with a first guide slope 431 for guiding and engaging with the first buckle 41, and the second clip segment 44 has at least one end provided with a second guide slope 441 for guiding and engaging with the second buckle 42. In this invention, both ends of the first clip segment 43 are provided with the first guide slope 431, and both ends of the second clip segment 44 are provided with the second guide slope 441.

[0045] like Figure 1-8 As shown in Figures 10-12, in order to improve the sealing performance, the inner bottom of the upper cover 3 is provided with an upper cover sealing plug 312 for fastening into the opening of the container body 1.

[0046] like Figure 12 As shown, to facilitate opening the container body opening, the upper cover sealing plug 312 has a sealing plug notch 3121 on its side wall. When the upper cover 3 is flipped relative to the cover seat 2, causing the first locking strip 43 to separate from the first buckle 41, and the second locking strip 44 to remain engaged with the second buckle 42, the opening of the container body 1 can be opened. When flipping the upper cover, only a small rotation of the upper cover relative to the cover seat is needed to allow the sealing plug notch to connect the container body opening to the outside.
