Description

Technical Field

[0001] This utility model belongs to the field of packaging material technology, and relates to frame paper, specifically to a frame paper with a composite cushioning structure. Background Technology

[0002] Frame paper is the stiff paper that provides support inside a cardboard box, consisting of a front sheet and two side sheets, both connected to the front sheet. Frame paper is widely used in cigarette packaging. Existing frame paper side supports are mostly single-layer cardboard structures, which are prone to plastic deformation under pressure, making them unable to spring back to their initial state. Data shows that existing single-layer frame paper, after undergoing plastic deformation exceeding 30% under pressure, cannot spring back, resulting in a reuse rate of less than 50%.

[0003] During use, the frame paper is easily compressed under stress. When the pressure on the frame paper is removed, the frame paper cannot recover. There is a technical problem that the frame paper cannot recover after deformation. There is an urgent need to design a frame paper with a composite cushioning structure.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0042] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0043] refer to Figures 1 to 3 A composite cushioning structure for paperboard includes: a front support plate 1 for protecting the front of the paperboard box; and two side support plates 2, which are respectively connected to the two ends of the front support plate 1 in the width direction for protecting the sides of the paperboard box. The side support plates 2 include a first plate 3 and a second plate 5 that are elastically connected, so that the side support plates 2 are suitable for automatic reset after being compressed. That is, when the front is subjected to pressure and the pressure is within the bearing capacity of the side support plates 2, the side support plates 2 are suitable for automatic reset after the pressure is removed.

[0044] In some embodiments, the first plate 3 is connected to the front support plate 1; the second plate 5 is separated from the front support plate 1; a tensioning connector 4 is provided between the first plate 3 and the second plate 5 to separate the first plate 3 and the second plate 5 so that when the front support plate 1 is subjected to force, the first plate 3 and the second plate 5 are close to each other to buffer the force, and at the same time, after the force is removed, the first plate 3 and the second plate 5 are driven to return to their original state.

[0045] In some embodiments, the tensioning connector 4 includes a first end 41 connected to the first plate 3 and a second end 42 connected to the second plate 5; the middle part of the tensioning connector 4 is U-shaped or V-shaped; the tensioning connector 4 is separated from the front support plate 1 to ensure that the tensioning connector 4 separates the first plate 3 and the second plate 5.

[0046] In some embodiments, the tensioning connector 4 is made of an elastic material, preferably spring steel; there are multiple tensioning connectors 4 to achieve the desired effect.

[0047] In some embodiments, the first plate 3 is provided with an insert 31; the second plate 5 is provided with a connecting groove 51 for fitting the insert 31, so as to achieve connection between the first plate 3 and the second plate 5 when they are close together.

[0048] In some embodiments, the inserts 31 are evenly distributed on the first plate 3; the bottom of the connecting groove 51 is provided with a resilient reset member 52 so that after the inserts 31 are inserted too deeply into the connecting groove 51, the inserts 31 are pushed away from the bottom of the connecting groove 51, so as to provide the force for the first plate 3 and the second plate 5 to recover, and at the same time to buffer the force on the frame paper.

[0049] In some embodiments, the insert 31 is made of a rigid material, preferably plastic; the reset member 52 is fixedly connected to the bottom of the connecting groove 51 to prevent the reset member 52 from separating from the connecting groove 51; the reset member 52 is made of silicone rubber or polyurethane.

[0050] In some embodiments, the tensioning connector 4 is located between two adjacent inserts 31; the tensioning connector 4 is separated from the inserts 31 and the connecting groove 51 to avoid interference.

[0051] In some embodiments, the first plate 3 and the front support plate 1 are integrally formed to ensure good stability; the first plate 3 and the second plate 5 are adapted to rotate along the front support plate 1 to facilitate the installation of the frame paper into the paper box.

[0052] Working principle: When preparing to use the frame paper, first place the frame paper in the paper box. At this time, the front support plate 1 is close to the front of the paper box, and the two side support plates 2 are in contact with the sides of the paper box. When an external force is applied to the front of the paper box, the tensioning connector 4 will be partially compressed under the influence of the external force, and the second plate 5 and the first plate 3 will move closer to each other. As the force continues to increase, the first plate 3 and the second plate 5 move closer to each other until the insert 31 is inserted into the connecting groove 51, and the reset piece 52 will also be partially compressed. When the applied external force disappears, under the action of the reset piece 52 and the tensioning connector 4, the first plate 3 and the second plate 5 separate, and the frame paper returns to its initial state.

[0053] This invention achieves automatic reset of the frame paper after being compressed by the synergistic action of an elastic tensioning connector (U / V-shaped structure) and a slot structure with a reset component. Thanks to the elastic reset structure, the frame paper can fully recover its initial shape after being subjected to pressure of ≤10N, increasing the reusability rate by over 40%. When the pressure disappears, the elastic deformation portion of the tensioning connector 4 generates a rebound force, while the reset component 52 pushes the insert 31 outward, achieving automatic reset through this dual action.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0055] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
