Description

Technical Field

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

[0002] In containers with lids in related technologies, the adhesive strips connecting the lid and the container body have high strength in order to ensure the reliability of the seal between the lid and the container body. This is especially true for food plastic containers with high-temperature cooking-grade lids, where a large tearing force is required when tearing the lid, resulting in a poor user experience for consumers, especially the elderly and children.

[0003] The above statements are for the purpose of providing background information in relation to this application only, and do not necessarily constitute prior art. Utility Model Content

[0004] The purpose of this application is to provide a container that addresses the problem that the adhesive strip connecting the lid film and the container body has high strength, requiring a large tearing force when tearing the lid film, resulting in a poor user experience for consumers, especially the elderly and children.

[0005] To achieve the above objectives, a first aspect of this application provides a container, comprising: a container body including a top opening and an edge portion disposed along the outer periphery of the top opening on the outside of the top opening; and a cover film covering the top opening and the upper side of the edge portion, the cover film being connected to the edge portion by an adhesive strip to seal the top opening, the adhesive strip being closedly disposed along the outer periphery of the top opening, including an adhesive strip body and a protruding structure protruding relative to the adhesive strip body toward a side away from the top opening.

[0006] In some embodiments of the container, the protruding structure is a V-shaped structure, with the tip of the V-shaped structure located on the side away from the top opening.

[0007] In some embodiments of the container, the angle of the tip of the V-shaped structure is acute, right, or obtuse.

[0008] In some embodiments of the container, the cover film also includes a tear-off portion disposed on the side of the cover film away from the top opening of the protruding structure.

[0009] In some embodiments of the container, the adhesive strip is a heat-sealing strip formed by heating the cover film.

[0010] In some embodiments of the container, the width of the adhesive strip is between 1.5 mm and 10 mm.

[0011] In some embodiments of the container, the protruding structure protrudes from the adhesive strip body by a distance greater than or equal to 1.5 mm.

[0012] In some embodiments of the container, the edge includes an inclined surface that slopes upward or downward relative to the top opening, and the adhesive strip is located on the inclined surface.

[0013] In some embodiments of the container, the angle at which the inclined surface is tilted upward or downward relative to the top opening is between 5 and 10 degrees.

[0014] In some embodiments, the container is a food-grade plastic container with a high-temperature retort-grade lid.

[0015] By setting a protruding structure that extends away from the top opening relative to the adhesive strip body, a breakthrough point is provided for tearing the cap film from the container body. This reduces the tearing force required to tear the cap film while minimizing the impact of the protruding structure on the sealing performance of the container body, thereby improving the consumer experience.

[0027] Unless otherwise required by the content, throughout the following description, the word “including” and its variations, such as “comprising” and “having”, will be interpreted in an open-ended, inclusive sense, that is, as “including but not limited to”.

[0028] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0029] like Figures 1 to 3 As shown, the container in this embodiment includes a container body 10 and a lid 20. The container body 10 includes a top opening 10A and an edge portion 11 disposed along the outer periphery of the top opening 10A. The lid 20 covers the top opening 10A and the upper side of the edge portion 11, and the lid 20 is connected to the edge portion 11 by an adhesive strip B to seal the top opening 10A. The adhesive strip B is closedly disposed along the outer periphery of the top opening 10A and includes an adhesive strip body B1 and a protruding structure B2 protruding from the adhesive strip body B1 toward the side away from the top opening 10A.

[0030] By providing a protruding structure B2 that protrudes from the adhesive strip body B1 away from the top opening 10A, a breakthrough point is provided for tearing the cover film 20 from the container body 10. This reduces the tearing force required to tear the cover film 20 while minimizing the impact of the protruding structure B2 on the sealing performance of the container body 10, thereby improving the consumer experience.

[0031] like Figures 1 to 3 As shown, in some embodiments of the container, the protruding structure B2 is a V-shaped structure, with the tip of the V-shaped structure located on the side away from the top opening 10A.

[0032] The protruding structure B2 adopts a V-shaped structure, and the cover film 20 is easier to tear at the apex of the V-shaped structure, thereby reducing the tearing force used to tear the cover film 20.

[0033] like Figure 1 As shown, in some embodiments of the container, the angle of the tip of the V-shaped structure is acute, right, or obtuse.

[0034] By adjusting the angle of the tip of the V-shaped structure, the tearing force required to tear the cap film 20 can be adjusted, thus achieving the best user experience. The smaller the angle of the tip of the V-shaped structure, the less tearing force is required; the larger the angle of the tip of the V-shaped structure, the less impact the protruding structure B2 has on the sealing performance of the container body 10.

[0035] like Figure 1 As shown, in some embodiments of the container, the cover film 20 also includes a tear-off portion 21, which is disposed on the side of the cover film 20 located away from the top opening 10A of the protruding structure B2.

[0036] By providing a tearing part 21, which is located on the side of the cover film 20 away from the top opening 10A of the protruding structure B2, an operational force is provided for the consumer to apply tearing force to tear the cover film 20, thereby improving the consumer's user experience.

[0037] like Figure 1 As shown, in some embodiments of the container, the adhesive strip B is a heat-sealing strip formed by heating the cover film 20.

[0038] The adhesive strip B is in the form of a heat-sealing strip formed by heating the cover film 20, which avoids the need to set an additional adhesive strip B to connect the cover film 20 and the container body 10, thereby simplifying the production process and reducing production costs.

[0039] like Figure 1 As shown, in some embodiments of the container, the width of the adhesive strip B is between 1.5 mm and 10 mm.

[0040] By setting the width of the adhesive strip B appropriately, it is easier to control the tearing force required to peel off the cover film 20, thereby improving the user experience.

[0041] like Figure 1 As shown, in some embodiments of the container, the protruding structure B2 protrudes from the adhesive strip body B1 by a distance greater than or equal to 1.5 mm.

[0042] By reasonably setting the distance of the protruding structure B2 relative to the adhesive strip body B1, it is convenient to control the tearing force required to tear the cover film 20, while reducing the structural impact of the protruding structure B2 on the container body 10 and the cover film 20, as well as reducing the impact of the protruding structure B2 on the sealing ability of the container body 10.

[0043] like Figures 2 to 3 As shown, in some embodiments of the container, the edge portion 11 includes an inclined surface 111 that slopes upward or downward relative to the top opening 10A, and the adhesive strip B is located on the inclined surface 111.

[0044] By setting an inclined surface 111 that is tilted upward or downward relative to the top opening 10A, the contents spilled on the inclined surface 111 can automatically slide down, avoiding the contents remaining on the edge 11, thereby improving the reliability of the seal between the cover film 20 and the edge 11.

[0045] like Figures 2 to 3 As shown, in some embodiments of the container, the inclined surface 111 is inclined upward or downward at an angle between 5 degrees and 10 degrees relative to the top opening 10A.

[0046] By reasonably setting the angle of the inclined surface 111 relative to the top opening 10A, the contents spilled on the inclined surface 111 can automatically slide down while ensuring that the cover film 20 is connected to the edge 11, thereby avoiding the contents remaining on the edge 11 and affecting the seal of the cover film 20.

[0047] like Figures 2 to 3 As shown, in some embodiments, the container is a food-grade plastic container with a high-temperature retort-grade lid.

[0048] The following combination Figures 1 to 3 The containers of the embodiments of this application will be described in more detail.

[0049] like Figures 1 to 3 As shown, the container in this embodiment is a food plastic container with a high-temperature cooking-grade lid, including a container body 10 and a lid 20.

[0050] The container body 10 includes a top opening 10A and an edge portion 11 disposed along the outer periphery of the top opening 10A outside the top opening 10A. The top opening 10A is circular. In embodiments not shown, the top opening 10A can be other shapes, such as elliptical, rectangular, etc.

[0051] like Figure 2 As shown, the edge portion 11 includes an inclined surface 111 that slopes upward relative to the top opening 10A. The angle between the inclined surface 111 and the horizontal plane is denoted by A. In other embodiments, such as Figure 3 As shown, the edge portion 11 includes an inclined surface 111 that slopes downward relative to the top opening 10A. The angle between the inclined surface 111 and the horizontal plane is denoted by A. Figure 2 or Figure 3 In the embodiment shown, the angle A between the inclined surface 111 and the horizontal plane is between 5 degrees and 10 degrees, and the angle at which the inclined surface 111 is inclined upward or downward relative to the top opening 10A is, for example, 6 degrees, 7 degrees, 8 degrees, or 9 degrees.

[0052] A cover film 20 covers the top opening 10A and the upper side of the edge portion 11. The cover film 20 is connected to the edge portion 11 by an adhesive strip B to seal the top opening 10A. The adhesive strip B is disposed along the outer periphery of the top opening 10A. The width of the adhesive strip B is between 1.5 mm and 10 mm. For example, the width of the adhesive strip B is 2 mm, 5 mm, or 8 mm. The adhesive strip B includes an adhesive strip body B1 and a V-shaped structure protruding from the adhesive strip body B1 away from the top opening 10A. The tip of the V-shaped structure is located on the side away from the top opening 10A. The distance by which the V-shaped structure protrudes from the adhesive strip body B1 is greater than or equal to 1.5 mm. The distance by which the V-shaped structure protrudes from the adhesive strip body B1 can be, for example, 1.8 mm, 2 mm, or 2.5 mm.

[0053] The angle of the tip of the V-shaped structure is preferably an acute angle, such as 45 degrees. The angle of the tip of the V-shaped structure can be adjusted according to the specific requirements of container processing. The V-shaped structure is not limited to the form of a sharp angle. In some embodiments of the container not shown, the connection between the two sides of the V-shaped structure can be rounded. The protruding structure B2 is not limited to the form of a V-shaped structure. For example, in some embodiments of the container not shown, the protruding structure B2 can be an arc-shaped structure.

[0054] In this embodiment, the adhesive strip B is a heat-sealing strip formed by heating the cover film 20. In some embodiments, the heat-sealing strip needs to be heated twice.

[0055] The adhesive strip B is not limited to the form of a heat-sealing strip. For example, in some embodiments not shown, the adhesive strip B is in the form of an adhesive strip.

[0056] The cover film 20 also includes a tear-off portion 21, which is disposed on the side of the cover film 20 located away from the top opening 10A of the protruding structure B2. The tear-off portion 21 provides an operating force portion for opening the cover film 20.

[0057] The cover film 20 can be any suitable material, including plastic such as polypropylene, or a composite film of metal and plastic. The cover film 20 can be flat or embossed, and can be in various colors.

[0058] The following describes the structure, parameters, and preparation process of a container according to an embodiment of this application.

[0059] The container body 10 is a round bowl made of PP material, with an outer diameter of 142 mm at the rim (i.e., the outer diameter of the edge 11). The angle A between the inclined surface 111 and the horizontal plane is 10 degrees. The lid film 10 is a composite film of AlOx-PET12 / Ink and NY15 / RCPP70. When sealing the container, the food processing plant heats the lid film 20 located on the inclined surface 111 at 190°C for 1.5 seconds, and heats it twice to form a heat seal strip with an outer diameter of 136 mm, an inner diameter of 130 mm, and a width of 3 mm. The heat seal strip forms a V-shaped structure on the side near the tear-off portion 21, with the tip of the V-shaped structure located away from the top opening 10A, and the tip of the V-shaped structure is 2 mm away from the outer edge of the heat seal strip. This achieves the sealing of the food inside the container.

[0060] The containers implemented in this application underwent burst pressure tests at 50 kPa and 90 kPa in GB / T15171-1994 "Test Method for Sealing Performance of Flexible Packaging", and showed no leakage, thus passing the tests. According to test method 6.6.2.2 in GB / T41220-2021 "Composite Plastic Cover Film for Food Packaging", the improved tear strength was reduced from an average of 32.25 N / mm to an average of 19.90 N / mm, a decrease of 38.29%. This meets the requirements for peelability in GB / T41220-2021 "Composite Plastic Cover Film for Food Packaging" while also satisfying the product's sealing performance test requirements.

[0061] When consumers consume food from the container, they apply tearing force to the lid film 20 through the tearing part 21. Since the heat seal has a V-shaped structure on the side near the tearing part 21, the tearing force required to tear the lid film 20 is greatly reduced under the same heat sealing conditions, thus improving the consumer's user experience.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and not to limit them; although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this application or equivalent substitutions can be made to some technical features, all of which should be covered within the scope of the technical solutions claimed in this application.
