Description

Technical Field

[0001] The invention relates to the technical field of container quick sealing and unsealing structures, in particular to a box-shaped or cup-shaped quick sealing and unsealing structure. Background Art

[0002] In the production and processing of some products (such as food, etc.), it is necessary to use various containers to package and seal them so as to obtain a complete saleable unit. The current sealing methods of sealed containers can be roughly divided into the following types: ① Using a spiral cover to connect and seal with the container body (for example, the sealing structure of some products such as toothpaste); ② Using a snap-on cover to connect and seal with the container body; ③ Using a brittle cover or sealing part to connect and seal with the container body (for example, sealing structures such as cans); ④ Using a film structure such as tin foil to connect and seal with the container body (for example, the sealing structure of yogurt, porridge and other foods on the market); ⑤ Using a spiral cover and a brittle limit ring to connect and seal with the container body (for example, the sealing structure of plastic beverage bottles such as cola on the market).

[0003] Although the sealing methods of the above-mentioned sealed containers can meet certain usage requirements, when sealing methods No. 1 and No. 2 are used for sealing, when the product is unsealed and then sealed again, its shape is the same as the original factory shape, resulting in consumers being unable to determine whether the product has been opened; when sealing methods No. 3 and No. 4 are used for sealing, the product cannot be sealed again after being unsealed, causing inconvenience to consumers; when sealing method No. 5 is used for sealing, although it can help consumers distinguish whether the product has been opened, it cannot quickly repackage qualified products; therefore, there is still room for improvement.

[0004] After searching, the Chinese patent application number CN201920286637.X discloses a food packaging box with good sealing performance, including a placement part, a cover part is provided on one side of the placement part, the placement part and the cover part are connected by a connecting part, a sealing groove is provided at the top edge of the placement part, and a sealing auxiliary component 1 and a card holder are provided at the edge corners of the placement part, and a card slot corresponding to the sealing groove is provided on the side of the cover part adjacent to the placement part, and a sealing strip matching the sealing groove is provided in the card slot, and an elastic card block and a through hole are provided on the outside of the card slot and at the top corners of the cover part, respectively, and the elastic card block matches the card holder, and a sealing auxiliary component 2 matching the sealing auxiliary component 1 is provided in the through hole. The food packaging box in the above patent has the following shortcomings: although it can meet certain packaging requirements, when the food packaging box is unsealed and sealed again, its shape is the same as the original factory shape, which makes it impossible for consumers to determine whether the product has been opened, and the food packaging box has a complex structure that is not conducive to production. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a box-shaped or cup-shaped quick sealing and unsealing structure.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A box-shaped or cup-shaped quick-sealing and unsealing structure comprises a container body, a container cover, and a surround-type sealing component, wherein a container outer eave is integrally provided at the edge of the top outer wall of the container body, a cover eave is integrally provided at the edge of the container cover, and the container cover is clamped to the outside of the container outer eave of the container body through the cover eave, a uniformly distributed top limiting component is provided at the top of the surround-type sealing component, and a uniformly distributed first limiting spring tooth is integrally provided at the bottom of the surround-type sealing component, the bottom surface of the first limiting spring tooth is an inclined structure, and the first limiting spring teeth are all inclined toward the inner and upper sides of the surround-type sealing component; an easy-to-break groove is provided on the outer wall of one side of the surround-type sealing component; the surround-type sealing component is clamped to the outside of the cover eave of the container cover; the cover eave is clamped between the top limiting component and the first limiting spring tooth; the shapes of the container body, the container cover and the surround-type sealing component are adapted.

[0008] Preferably: the top limiting assembly includes a limiting base and a first limiting portion, the limiting base is integrally arranged on the top outer wall of the surrounding sealing assembly, the same brittle connection portion is arranged at the bottom side edge of the limiting base and the top side edge of the first limiting portion, and a second limiting portion is integrally arranged on the outer wall on one side of the first limiting portion; the bottom end of the first limiting portion is clamped in the gap between the cover eaves and the surrounding sealing assembly, and the cover eaves is clamped between the first limiting spring tooth and the second limiting portion.

[0009] Furthermore: the inner wall of the cover eave is integrally provided with first limiting protrusions distributed at equal intervals; the outer eave of the container is clamped between the top inner wall of the cover eave and the top outer wall of the first limiting protrusion.

[0010] Further preferably, the circumferential inner wall of the cover eave is integrally provided with a surrounding second limiting protrusion, and the outer eave of the container is clamped between the top inner wall of the cover eave and the top outer wall of the second limiting protrusion.

[0011] As a preferred embodiment of the present invention, the top limiting assembly is replaced by a top limiting head, the top of the top limiting head is an inclined structure, and the bottom of the top limiting head is a flat structure adapted to the top of the cover eaves.

[0012] As a further preferred embodiment of the present invention: the distance between the bottom surface of the top limiting head and one end of the first limiting spring tooth close to the surrounding sealing assembly is greater than the thickness of the cover eaves.

[0013] As a further preferred embodiment of the present invention: the top limiting head is replaced by a second limiting spring tooth, the shape of the second limiting spring tooth is adapted to the first limiting spring tooth, and the second limiting spring tooth is symmetrically arranged with the first limiting spring tooth.

[0014] As a further solution of the present invention: the container body, the container cover and the surrounding sealing assembly are in a circular, elliptical, rectangular, square, triangular or other closed-loop shape.

[0015] On the basis of the above scheme: the container body and the container cover cooperate to form a box-type container, a cup-type container, a bottle-type container or a barrel-type container.

[0016] Based on the above scheme, it is preferred that the materials of the container body, container cover, surround sealing assembly, top limit assembly, first limit spring tooth and second limit spring tooth are one or more of plastic material, fiber material, food grade PP / PET, starch, paper, wood, bio-based degradable material and metal material.

[0017] The beneficial effects of the present invention are:

[0018] 1. The present invention provides structures such as a surround-type sealing assembly, so that when sealing and installing, the container cover can be connected to the outside of the container outer eaves of the container body through the cover eaves, and then the surround-type sealing assembly is clamped downward on the cover eaves. During this period, the first limiting spring tooth smoothly passes through the cover eaves in a deformed manner. When the cover eaves and the first limiting spring tooth are separated, the first limiting spring tooth is reset based on the rebound force. At this time, the cover eaves is limited by the top limiting assembly and the first limiting spring tooth. Since the first limiting spring tooth is inclined toward the inner and upper side of the surround-type sealing assembly, the cover eaves can be firmly limited to its top and ensure that The method not only retains the structural integrity of the container body and the container cover, so that they can still be sealed and used, but also has obvious differences from the factory state after unsealing, which is conducive to consumers' identification. In addition, after unsealing, the design can only take a new surrounding sealing component and re-seal it on the outside of the container body and the container cover, which is conducive to manufacturers to quickly seal qualified products again, saving costs and ensuring economic benefits.

[0019] 2. By providing the first limiting part, the second limiting part and the brittle-break connection part, during installation, the limiting base and the first limiting part can be kept in a parallel state first, so that there is enough space between the first limiting spring tooth and the first limiting part for the first limiting spring tooth to deform. When the cover eaves is stuck on the first limiting spring tooth from bottom to top, the first limiting part is rotated downward with the brittle-break connection part as the axis, and the deformation of the first limiting part is used to make the bottom end of the first limiting part stuck in the gap between the cover eaves and the surrounding sealing assembly. At this time, the second limiting part is located above the cover eaves, so as to achieve the purpose of limiting the movement of the cover eaves, and due to the rotation of the first limiting part, the movement space of the cover eaves is reduced, thereby ensuring the compactness and firmness of the structure. When unsealing, the user can also bend the first limiting part upward until the brittle-break connection part breaks, thereby removing the container cover and the container body from above the surrounding sealing assembly. The operation is convenient, the structure is simple and reliable, and the practicability is strong.

[0020] 3. By providing the first limiting protrusion or the second limiting protrusion, the outer edge of the container can be firmly restricted to the inner side of the cover edge, preventing the container body from being separated from the container cover without the action of external force, thereby improving reliability.

[0021] 4. By setting up structures such as the top limit head, when in use, the container cover can be first installed downward into the surround-type sealing assembly. Since the top of the top limit head is a sloped structure, it is convenient to cooperate with the surround-type sealing assembly to be inserted in a deformed manner, and then the container body is installed upward from the bottom of the surround-type sealing assembly. During this period, the first limit spring tooth deforms to allow the container outer edge of the container body to pass smoothly. When the container outer edge and the first limit spring tooth are separated, the first limit spring tooth is reset based on the rebound force. As the container outer edge moves upward, with the cooperation of the deformation of the cover edge, the container outer edge is reliably stuck between the second limit protrusion and the cover edge, completing the sealing installation work, and the structure is simpler and easy to produce.

[0022] 5. By providing a second limiting spring tooth that is compatible with the first limiting spring tooth, it is possible to facilitate the installation of the container cover from the upper and lower directions of the surround-type sealing assembly. During the installation process, the second limiting spring tooth or the first limiting spring tooth can be tilted outward to ensure that the container cover is smoothly installed, thereby improving the installation flexibility while meeting the requirements of sealing and structural firmness.

[0040] Embodiment 1:

[0041] A box-shaped or cup-shaped quick-seal unsealing structure, such as Figure 1 , Figure 2As shown, it includes a container body 1, a container cover 2 and a surrounding sealing component 4, wherein a container outer eave 8 is integrally provided at the edge of the top outer wall of the container body 1, and a cover eave 7 is integrally provided at the edge of the container cover 2. The container cover 2 is clamped to the outside of the container outer eave 8 of the container body 1 through the cover eave 7, and the top of the surrounding sealing component 4 is provided with evenly distributed top limiting components 5, and the bottom of the surrounding sealing component 4 is integrally provided with evenly distributed first limiting spring teeth 6, and the bottom surface of the first limiting spring teeth 6 is an inclined structure. The first limiting spring teeth 6 are all inclined upwardly and inside the surrounding sealing component 4; the outer wall of one side of the surrounding sealing component 4 is provided with an easy-to-break groove 3; the surrounding sealing component 4 is clamped to the outer side of the cover eave 7 of the container cover 2; the cover eave 7 is clamped between the top limiting component 5 and the first limiting spring teeth 6; the shapes of the container body 1, the container cover 2 and the surrounding sealing component 4 are adapted; by providing the surrounding sealing component 4 and other structures, the container cover 2 can be clamped to the outer side of the container outer eave 8 of the container body 1 through the cover eave 7 during the sealing installation. The first limiting spring tooth 6 is reset based on the rebound force when the cover eave 7 is separated from the first limiting spring tooth 6. At this time, the cover eave 7 is limited by the top limiting component 5 and the first limiting spring tooth 6. Since the first limiting spring tooth 6 is inclined upwardly toward the inner side of the surrounding sealing component 4, the cover eave 7 can be firmly limited to its top and the firmness of the structure is guaranteed. When unsealing is required, the user can move the surrounding sealing component 4 downwardly to the cover eave 7. The container body 1 and the container cover 2 can be smoothly taken out by breaking off the easy-to-break groove 3 of the sealing component 4 with force. This method not only retains the structural integrity of the container body 1 and the container cover 2, so that they can still be sealed and used, but also there is a clear difference between the factory state after unsealing, which is conducive to consumers to distinguish; in addition, after unsealing, this design can only take a new surrounding sealing component 4 and re-sleeve it on the outside of the container body 1 and the container cover 2, which is conducive to the manufacturer to quickly seal the qualified products again, saving costs and ensuring economic benefits.

[0042] In order to improve the reliability of the card connection; Figure 2As shown, the top limiting component 5 includes a limiting base 9 and a first limiting portion 10, the limiting base 9 is integrally arranged on the top outer wall of the surrounding sealing component 4, the bottom side of the limiting base 9 and the top side of the first limiting portion 10 are provided with the same brittle connection portion 13, and the outer wall of one side of the first limiting portion 10 is integrally provided with a second limiting portion 11; the bottom end of the first limiting portion 10 is clamped in the gap between the cover eaves 7 and the surrounding sealing component 4, and the cover eaves 7 is clamped between the first limiting spring tooth 6 and the second limiting portion 11; by providing the first limiting portion 10, the second limiting portion 11 and the brittle connection portion 13, during installation, the limiting base 9 and the first limiting portion 10 can be kept in a parallel state first, so that there is a gap between the first limiting spring tooth 6 and the first limiting portion 10. There is enough space for the first limiting spring tooth 6 to deform. When the cover eave 7 is stuck on the top of the first limiting spring tooth 6 from bottom to top, the first limiting part 10 is rotated downward with the brittle connection part 13 as the axis. The deformation of the first limiting part 10 is used to make the bottom end of the first limiting part 10 stuck in the gap between the cover eave 7 and the surrounding sealing component 4. At this time, the second limiting part 11 is located above the cover eave 7, so as to achieve the purpose of limiting the movement of the cover eave 7. Due to the rotation of the first limiting part 10, the movement space of the cover eave 7 is reduced, thereby ensuring the compactness and firmness of the structure. When unsealing, the user can also bend the first limiting part 10 upward until the brittle connection part 13 breaks, thereby removing the container cover 2 and the container body 1 from above the surrounding sealing component 4. The operation is convenient, the structure is simple and reliable, and the practicability is strong.

[0043] In order to improve the firmness of the connection between the container body 1 and the container cover 2; Figure 2 As shown, the inner wall of the cover eave 7 is integrally provided with first limiting protrusions 12 distributed equidistantly; the container outer eave 8 is clamped between the top inner wall of the cover eave 7 and the top outer wall of the first limiting protrusion 12; by providing the first limiting protrusion 12, the container outer eave 8 can be firmly restricted to the inner side of the cover eave 7, preventing the container body 1 from being separated from the container cover 2 without the action of external force, thereby improving reliability.

[0044] The container body 1 is in a box-shaped structure.

[0045] When sealing and installing the present embodiment, the user clamps the container cover 2 to the outer side of the container outer edge 8 of the container body 1 through the cover edge 7, firstly makes the limiting base 9 and the first limiting part 10 maintain a parallel state, so that there is enough space between the first limiting spring tooth 6 and the first limiting part 10 for the first limiting spring tooth 6 to deform, and clamps the cover edge 7 from bottom to top above the first limiting spring tooth 6, during which the first limiting spring tooth 6 smoothly passes through the cover edge 7 in a deformed manner, and when the cover edge 7 and the first limiting spring tooth 6 are separated, the first limiting spring tooth 6 is reset based on the rebound force, and since the first limiting spring tooth 6 is inclined toward the inner and upper side of the surrounding sealing component 4, the cover edge 7 can be firmly limited to its top, and the user rotates the first limiting part 10 downward with the brittle connection part 13 as the axis, and utilizes the deformation of the first limiting part 10 to make the bottom end of the first limiting part 10 clamped in the gap between the cover edge 7 and the surrounding sealing component 4, at this time the second limiting part 11 It is located above the cover eaves 7 to limit the movement of the cover eaves 7, and due to the rotation of the first limiting part 10, the movement space of the cover eaves 7 is reduced, thereby ensuring the compactness and firmness of the structure; when it is necessary to unseal, the user can forcefully break the easy-to-break groove 3 of the surrounding sealing component 4, and then smoothly take out the container body 1 and the container cover 2, or bend the first limiting part 10 upward until the brittle connection part 13 breaks, thereby taking out the container cover 2 and the container body 1 from above the surrounding sealing component 4. This method not only retains the structural integrity of the container body 1 and the container cover 2, so that they can still be sealed and used, but also has obvious differences from the factory state after unsealing, which is conducive to consumers' identification; in addition, after unsealing, this design can only take a new surrounding sealing component 4 and re-sleeve it on the outside of the container body 1 and the container cover 2, which is conducive to the manufacturer to quickly seal the qualified products again, saving costs and ensuring economic benefits.

[0046] Embodiment 2:

[0047] A box-shaped or cup-shaped quick-seal unsealing structure, such as Figure 3 , Figure 4 As shown, in order to meet the packaging requirements of containers of different shapes, this embodiment makes the following changes based on Embodiment 1: the container body 1 is replaced with a cup-shaped structure.

[0048] In order to facilitate reliable fixing of the container body 1 and the container cover 2; Figure 4 As shown, the circumferential inner wall of the cover eave 7 is integrally provided with a surrounding second limiting protrusion 14 , and the container outer eave 8 is clamped between the top inner wall of the cover eave 7 and the top outer wall of the second limiting protrusion 14 .

[0049] Embodiment 3:

[0050] A box-shaped or cup-shaped quick-seal unsealing structure, such as Figure 5 , Figure 6As shown, in order to provide another sealing method; this embodiment makes the following changes on the basis of embodiment 1: the top limit assembly 5 is replaced by a top limit head 15, the top of the top limit head 15 is a sloped structure, and the bottom of the top limit head 15 is a planar structure that is compatible with the top of the cover eaves 7.

[0051] To improve reliability; Figure 6 As shown, the distance between the bottom surface of the top limit head 15 and the end of the first limit spring tooth 6 close to the surrounding sealing component 4 is greater than the thickness of the cover eave 7; by setting the distance between the bottom surface of the top limit head 15 and the end of the first limit spring tooth 6 close to the surrounding sealing component 4 to be greater than the thickness of the cover eave 7, the first limit spring tooth 6 can have enough space to achieve reset after deformation, thereby improving reliability.

[0052] The container body 1 is in a box-shaped structure.

[0053] When the present embodiment is in use, the container cover 2 is first downwardly loaded into the surrounding sealing assembly 4. Since the top of the top limiting head 15 is an inclined structure, it is convenient to cooperate with the container cover 2 to be inserted in a deformed manner, and then the container body 1 is loaded upward from the bottom of the surrounding sealing assembly 4. During this period, the first limiting spring tooth 6 allows the container outer edge 8 of the container body 1 to pass smoothly in a deformed manner. When the container outer edge 8 and the first limiting spring tooth 6 are separated, the first limiting spring tooth 6 is reset based on the rebound force. As the container outer edge 8 moves upward, the container outer edge 8 is reliably stuck between the second limiting protrusion 14 and the cover eave 7 with the cooperation of the deformation of the cover eave 7. The sealing installation work is completed in the time; when it is necessary to unseal, the user can break off the easy-to-break groove 3 of the surrounding sealing component 4 with force, and then the container body 1 and the container cover 2 can be smoothly taken out. This method not only retains the structural integrity of the container body 1 and the container cover 2, so that they can still be sealed and used, but also has obvious differences from the factory state after unsealing, which is conducive to consumers to distinguish; in addition, after unsealing, this design can only take a new surrounding sealing component 4 and re-sleeve it on the outside of the container body 1 and the container cover 2, which is conducive to the manufacturer to quickly seal the qualified products again, saving costs and ensuring economic benefits.

[0054] Embodiment 4:

[0055] A box-shaped or cup-shaped quick-seal unsealing structure, such as Figure 7 , Figure 8 As shown, in order to meet the packaging requirements of containers of different shapes; this embodiment makes the following changes on the basis of Example 2: the top limit assembly 5 is replaced by a top limit head 15, the top of the top limit head 15 is a sloped structure, and the bottom of the top limit head 15 is a planar structure that is compatible with the top of the cover eaves 7.

[0056] To improve reliability; Figure 8As shown, the distance between the bottom surface of the top limiting head 15 and the end of the first limiting spring tooth 6 close to the surrounding sealing assembly 4 is greater than the thickness of the cover eave 7.

[0057] The container body 1 is in a cup-shaped structure.

[0058] Embodiment 5:

[0059] A box-shaped or cup-shaped quick-seal unsealing structure, such as Fig. 9 , Fig.10 As shown, in order to provide another sealing method; this embodiment makes the following changes on the basis of Example 3: the top limit head 15 is replaced by a second limit spring tooth 16, the shape of the second limit spring tooth 16 is adapted to the first limit spring tooth 6, and the second limit spring tooth 16 and the first limit spring tooth 6 are symmetrically arranged.

[0060] By providing a second limiting spring tooth 16 that is compatible with the first limiting spring tooth 6, it is possible to facilitate the installation of the container cover 2 from both the upper and lower directions of the surrounding sealing assembly 4. During the installation process, the second limiting spring tooth 16 or the first limiting spring tooth 6 can be tilted outward to ensure that the container cover 2 is smoothly installed, thereby improving the installation flexibility while meeting the requirements of sealing and structural firmness.

[0061] The container body 1 is in a box-shaped structure.

[0062] When the present embodiment is in use, the container cover 2 is first downwardly loaded into the surrounding sealing assembly 4. Since the second limiting spring tooth 16 and the first limiting spring tooth 6 are both inclined structures, it is convenient to cooperate with the container cover 2 to be inserted in a deformed manner, and then the container body 1 is loaded upward from the bottom of the surrounding sealing assembly 4. During this period, the first limiting spring tooth 6 allows the container outer edge 8 of the container body 1 to pass smoothly in a deformed manner. When the container outer edge 8 and the first limiting spring tooth 6 are separated, the first limiting spring tooth 6 is reset based on the rebound force. As the container outer edge 8 moves upward, the container outer edge 8 is reliably stuck on the second limiting protrusion 14 with the cooperation of the deformation of the cover edge 7. The sealing installation work is completed between the container body 1 and the cover eave 7; when it is necessary to unseal, the user can break off the easy-to-break groove 3 of the surrounding sealing component 4 with force, and then the container body 1 and the container cover 2 can be smoothly taken out. This method not only retains the structural integrity of the container body 1 and the container cover 2, so that they can still be sealed and used, but also has obvious differences from the factory state after unsealing, which is conducive to consumers to distinguish; in addition, after unsealing, this design can only take a new surrounding sealing component 4 and re-put it on the outside of the container body 1 and the container cover 2, which is conducive to manufacturers to quickly seal qualified products again, saving costs and ensuring economic benefits.

[0065] The container body 1 is in a cup-shaped structure.

[0066] In summary, the present invention proposes a box-type or cup-type quick sealing and unsealing structure, wherein the container body 1, the container cover 2, the surrounding sealing component 4, the top limiting component 5, the first limiting spring tooth 6 and the second limiting spring tooth 16 can all be made of various bio-based degradable materials, various plastic materials (including but not limited to such food-grade materials, etc.), various starch materials (including but not limited to such food-grade materials, etc.), various fiber materials (including but not limited to such food-grade materials, etc.), various paper, wood or other various food-grade materials, various metal materials such as aluminum alloy packaging materials, etc., including but not limited to the various materials listed above, etc., and can be adapted to various materials that need to achieve the purpose of sealing and packaging.
