Description

Technical Field

[0001] The present invention relates to the technical field of container cover structures, and in particular to a sealed cover structure for rapid packaging of containers. Background Art

[0002] Currently, most containers and their lid structures adopt a direct buckle combination method, such as self-flushing plastic milk tea cups. Although this method can meet certain sealing requirements, during transportation and use, the container and the lid are easily deformed and separated when subjected to squeezing, vibration and other external forces, causing the internal contents to spill out, bringing adverse effects. Therefore, how to strengthen the installation firmness of the structure between the container and the lid is a problem that needs to be solved.

[0003] After searching, the Chinese patent application number 201620050348.6 discloses a disposable milk tea cup. It includes a cup body 1 and a cup cover, and is characterized in that it also includes a trash cup, wherein the trash cup includes a cup body 2 with an inner cavity and an edge, and the inner cavity is divided into an upper cup bottom placement area and a lower garbage placement area. The cup bottom diameter of the cup body 1 is smaller than the cup mouth diameter of the cup body 2, and the cup bottom diameter of the cup body 1 is larger than the cup body diameter at the junction of the cup bottom placement area and the garbage placement area. The milk tea cup in the above patent has the following deficiencies: the cup body and the cup cover are prone to deformation and separation when subjected to squeezing, vibration and other external forces, causing the internal contents to spill out. Therefore, there is room for improvement. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a sealed cover structure for rapid packaging of a container.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A sealed cover structure for rapid packaging of a container, comprising:

[0007] A container assembly, the container assembly comprising a container body and a container eaves arranged on the outside of the top of the container body;

[0008] The cover assembly includes a cover body and a cover outer edge provided on the outside of the bottom of the cover body, and the cover assembly is detachably fastened to the outside of the container outer edge of the container body through the cover outer edge;

[0009] An annular sealing cover assembly is installed at the connection between the outer edge of the cover and the outer edge of the container;

[0010] Wherein, the annular cover assembly includes:

[0011] An annular connecting portion, the annular connecting portion is located on the outer side of the cover outer edge, and the annular connecting portion is provided with a brittle fracture groove;

[0012] The upper sealing and pressing part includes a first upper sealing and pressing body and a second upper sealing and pressing body. The first upper sealing and pressing body is arranged on the outer wall of the top of the annular connecting part, and the second upper sealing and pressing body is arranged inside the first upper sealing and pressing body. The second upper sealing and pressing body and the first upper sealing and pressing body form an L-shaped structure.

[0013] The lower sealing part includes a first lower sealing body and a second lower sealing body. The first lower sealing body is arranged on the inner side of the annular connecting part, and the second lower sealing body is arranged on the outer wall of the top of the first lower sealing body. When the annular sealing cover assembly is installed on the outer eaves of the cover and the outer eaves of the container, the second lower sealing body is stuck on the inner side of the outer eaves of the container, and the second upper sealing body is stuck on the top of the outer eaves of the cover.

[0014] Preferably, the sealed cover structure further comprises:

[0015] The top cover has a bottom circumferential outer wall connected to the second upper sealing and pressure body via a brittle-break connection portion.

[0016] Furthermore: a drinking port is provided on the cover body.

[0017] Further preferably, a spacer is provided in the drinking opening, and the edge of the spacer is connected to the inner wall of the drinking opening in a brittle fracture manner.

[0018] As a preferred embodiment of the present invention, the cross-sections of the outer eaves of the container and the outer eaves of the cover are in a matching L-shaped structure.

[0019] As a further preferred embodiment of the present invention: an inner protrusion is provided on a side of the outer edge of the cover close to the outer edge of the container, and the inner protrusion is annular in structure or is evenly distributed on the inner side of the outer edge of the cover.

[0020] As a further solution of the present invention: the upper sealing portion and the lower sealing portion are both circumferentially and equidistantly distributed on the annular connecting portion, and the upper sealing portion and the lower sealing portion are arranged in a staggered distribution.

[0021] Based on the above solution: an indicator mark is provided on the outer wall of one side of the first upper sealing and pressure body and the top cover.

[0022] Based on the above solution, it is preferred that the cover assembly, container assembly and annular sealing assembly are compatible with: round, square, oval or hexagonal bowl-shaped, box-shaped, barrel-shaped, cup-shaped or box-shaped structures.

[0023] Based on the above solution, it is further preferred that: the cover body assembly and the annular sealing cover assembly are in matching circular structures, and the annular sealing cover assembly is replaced with a detachable connection with the cover body assembly by means of threads or rotational engagement.

[0024] The beneficial effects of the present invention are:

[0025] 1. During installation, the present invention can buckle the cover assembly onto the outer side of the container outer edge of the container main body through the cover outer edge, and then move the annular cover assembly from top to bottom to elastically deform the second lower sealing pressure body into the inner side of the container outer edge, thereby achieving the purpose of limiting the bottom of the container outer edge by the second lower sealing pressure body and limiting the top of the cover outer edge by the second upper sealing pressure body, thereby achieving the purpose of strengthening the installation firmness of the cover assembly and the container assembly.

[0026] 2. The top cover of the present invention plays a role of sealing and dustproofing. When used without opening the main body of the cover, it is only necessary to pull the top cover upwards to break the brittle connection part and separate the top cover from the second upper sealing body, thereby exposing the main body of the cover for normal drinking through the drinking opening; when the main body of the cover needs to be opened, the annular connection part can be broken through the brittle groove, and the closed loop can be turned into an open loop, so that the annular sealing cover assembly can be removed, thereby unlocking the cover assembly and the container assembly, and the user can conveniently disassemble the cover assembly.

[0027] 3. When disassembling the present invention, after breaking off and separating the top cover, the second upper sealing body can be broken outward and then pulled toward the bottom of the container assembly to separate the annular sealing cover assembly from the corresponding container assembly; the advantage of this method is that the annular connection portion can still be kept intact for reuse.

[0028] 4. The present invention provides an inner protrusion, which can play a role in preventing the outer edge of the cover from retreating when it is stuck on the outer side of the outer edge of the container, thereby improving the structural strength. When it needs to be disassembled, the outer edge of the cover is deformed outward by applying external force, and the inner protrusion is moved outward synchronously, thereby separating the cover assembly from the container assembly.

[0029] 5. The present invention provides an indicator mark to serve as a reminder and facilitate user operation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0039] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0040] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0041] Example 1:

[0042] A sealed cover structure for rapid packaging of a container, such as Figure 1-8 Shown, including:

[0043] The container assembly includes a container body 13 and a container outer edge 15 integrally provided on the top outer side of the container body 13;

[0044] The cover assembly includes a cover body 11 and a cover outer edge 12 integrally provided on the outside of the bottom of the cover body 11. The cover assembly is detachably fastened to the outside of the container outer edge 15 of the container body 13 through the cover outer edge 12;

[0045] An annular sealing assembly is installed at the connection between the outer edge 12 of the cover and the outer edge 15 of the container;

[0046] Wherein, the annular cover assembly includes:

[0047] An annular connecting portion 1, the annular connecting portion 1 is located outside the outer edge 12 of the cover, and a brittle fracture groove 16 is provided on the annular connecting portion 1;

[0048] The upper sealing and pressing part 5 includes a first upper sealing and pressing body 8 and a second upper sealing and pressing body 7. The first upper sealing and pressing body 8 is integrally provided on the top outer wall of the annular connecting part 1, and the second upper sealing and pressing body 7 is integrally provided on the inner side of the first upper sealing and pressing body 8. The second upper sealing and pressing body 7 and the first upper sealing and pressing body 8 form an L-shaped structure.

[0049] The lower sealing part 6 includes a first lower sealing body 9 and a second lower sealing body 10. The first lower sealing body 9 is integrally arranged on the inner side of the annular connecting part 1, and the second lower sealing body 10 is integrally arranged on the outer wall of the top of the first lower sealing body 9. When the annular sealing cover assembly is installed on the outer eaves 12 of the cover and the outer eaves 15 of the container, the second lower sealing body 10 is stuck on the inner side of the outer eaves 15 of the container, and the second upper sealing body 7 is stuck on the top of the outer eaves 12 of the cover. The second lower sealing body 10 cooperates with the second upper sealing body 7 to press and fix the outer eaves 12 of the cover and the outer eaves 15 of the container based on their elastic force;

[0050] The top cover 4, the outer circumferential wall of the bottom of the top cover 4 is connected to the second upper sealing body 7 through the brittle connection part 3;

[0051] Wherein, the cover body 11 is provided with a drinking port;

[0052] A spacer is provided in the drinking opening, and the edge of the spacer is connected to the inner wall of the drinking opening in a brittle fracture manner;

[0053] The second upper sealing member 7 is then snapped back to its original position to allow the lid to be tightened and the lid closure 10 to be tightened.

[0054] In addition, the top cover 4 plays a role of sealing and dustproofing. When using the lid body 11 without opening it, it is only necessary to pull the top cover 4 upward to break the brittle connection part 3 and separate the top cover 4 from the second upper sealing body 7, thereby exposing the lid body 11 for normal drinking through the drinking opening; when the lid body 11 needs to be opened, the annular connection part 1 can be broken through the brittle groove 16, and the closed loop can be turned into an open loop, so that the annular sealing cover assembly can be removed, thereby unlocking the lid assembly and the container assembly, and the user can conveniently disassemble the lid assembly.

[0055] In addition, the user can also bend off and separate the top cover 4, then bend the second upper sealing body 7 outward, and pull it toward the bottom of the container assembly to separate the annular cover assembly from the corresponding container assembly; the advantage of this method is that the annular connection can still be kept intact for reuse.

[0056] In order to improve the firmness of the snap fit; Figure 8 As shown, the cross-sections of the container outer edge 15 and the cover outer edge 12 are adapted L-shaped structures.

[0057] In order to improve the firmness of the snap fit; Figure 8 As shown, the outer edge 12 of the cover is integrally provided with an inner protrusion 14 on one side close to the outer edge 15 of the container. The inner protrusion 14 is annular or equidistantly distributed on the inner side of the outer edge 12 of the cover;

[0058] By providing the inner protrusion 14, it can play a role in preventing the outer edge 12 of the cover from retreating when it is stuck on the outside of the outer edge 15 of the container, thereby improving the structural strength. When it needs to be disassembled, the outer edge 12 of the cover is deformed outward by applying external force, and the inner protrusion 14 is moved outward synchronously, thereby separating the cover assembly from the container assembly.

[0059] In order to improve the use effect; Figure 2-4 As shown, the upper sealing portion 5 and the lower sealing portion 6 are both circumferentially and equidistantly distributed on the annular connecting portion 1 , and the upper sealing portion 5 and the lower sealing portion 6 are staggered.

[0060] To improve practicality; Figure 1 As shown, the outer wall of one side of the first upper sealing body 8 and the top cover 4 is provided with an indicator mark 2;

[0061] The indicator mark 2 is provided to serve as a reminder and facilitate the operation of the user.

[0062] The cover assembly, container assembly and annular sealing assembly are in compatible shapes: round, square, oval or hexagonal bowl-shaped, box-shaped, barrel-shaped, cup-shaped or box-shaped structures.

[0063] The materials used for the cover assembly, container assembly and annular cover assembly have brittle fracture characteristics, such as aluminum and other metals, rubber, plastic, starch, paper, wood, bio-based materials and other biodegradable materials, etc.

[0064] The materials used for the cover assembly and the container assembly may also be food-grade stainless steel, glass, food-grade PP / PET, and the like.

[0065] Among them, there can be multiple options for the production and assembly of the cover body component, container component and annular sealing cover component, including but not limited to injection molding, vacuum molding, compression molding and other molding in a fully automatic or semi-automatic production line process, manual installation, manual installation using various tools, mechanical fully automatic installation, etc., because they are not limited to one or some methods, they are not listed in detail one by one.

[0066] There are also many ways to install this annular sealing cover assembly. In addition to first covering the cover body assembly with the container assembly and then assembling the annular sealing cover assembly, the cover body assembly that needs to be sealed and pressed can also be assembled with the annular sealing cover assembly in advance (for example, by gluing or structural inlaying, etc.), and then assembled together with the corresponding container assembly, and sealed and pressed into place. The material selected for the annular sealing cover assembly is deformable and rebounds to its original shape, which still ensures that this installation method can be successfully installed and sealed in place. The various installation methods are not limited to one or some methods, so they are not listed in detail one by one.

[0067] During installation, the cover assembly is fastened to the outer side of the container outer edge 15 of the container body 13 through the cover outer edge 12, and then the annular cover assembly is moved from top to bottom to elastically deform the second lower pressure sealing body 10 into the inner side of the container outer edge 15, thereby achieving the purpose of limiting the bottom of the container outer edge 15 by the second lower pressure sealing body 10 and limiting the top of the cover outer edge 12 by the second upper pressure sealing body 7, thereby achieving the purpose of strengthening the installation firmness of the cover assembly and the container assembly;

[0068] In addition, the top cover 4 plays a role of sealing and dustproofing. When it is needed, it is only necessary to pull the top cover 4 upward to break the brittle connection part 3, so that the top cover 4 can be separated for normal drinking through the drinking port, thereby improving practicality.

[0069] Example 2:
