Description

Technical Field

[0001] This utility model relates to the field of shoe tree technology, and in particular to a cardboard lining that enhances elasticity, removes marks, and resists wrinkles. Background Technology

[0002] Shoe trees, also known as shoe linings, are widely used in various types of shoes, such as foam shoe trees and cardboard shoe trees. Cardboard shoe trees are usually made of cardboard or corrugated paper and are mainly used for shoe packaging, transportation, or storage to prevent shoes from sagging and deforming. However, existing cardboard shoe trees will form wrinkles on the surface of the shoe tree during the thermoforming process. This makes it easy for the shoe tree to form grooves or bulges on the shoe surface when it is supporting the shoe, which seriously affects the appearance of the shoe. Therefore, it is necessary to design a new type of cardboard shoe tree structure to solve the above problems. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a cardboard body for a cardboard lining that enhances warping, removes wrinkles, and resists creases. The cardboard body has grooves in the eyelet reinforcement area and tongue area of ​​the corresponding shoe. When the cardboard body is hot-pressed, the grooves can provide space for the warped parts of the cardboard body during molding and reduce the wrinkles caused by the shrinkage of excess cardboard during hot pressing. In addition, the grooves correspond to the harder parts of the shoe upper material, so they are not easily deformed by the pressure of the grooves, so as to prevent the grooves from forming grooves or bulges on the shoe upper, which would seriously affect the appearance of the shoe.

[0004] A type of cardboard liner for enhancing warping, removing marks, and resisting wrinkles includes a cardboard body with a hollow, arched structure in the front half of a shoe. The top surface of the cardboard body has grooves on the corresponding shoe eyelet reinforcement area and the shoe tongue area to allow the cardboard body to be formed and warped.

[0005] Preferably, the groove includes one or more, and the groove is a trapezoidal groove.

[0006] Preferably, the protrusion includes one or more, and the protrusion is a trapezoidal ridge.

[0007] Preferably, the groove includes one or more, and the groove is a U-shaped groove.

[0008] Preferably, the protrusion includes one or more, and the protrusion is a U-shaped ridge.

[0009] Preferably, the plurality of grooves are arranged sequentially along the length of the cardboard body, and the width of the plurality of grooves gradually decreases toward the rear side of the cardboard body.

[0010] Preferably, the plurality of protrusions are arranged sequentially along the length direction of the cardboard body, and the width of the plurality of protrusions gradually decreases toward the rear side of the cardboard body.

[0011] Preferably, the groove is a corrugated groove with uneven surfaces.

[0012] Preferably, the protrusion is a corrugated ridge with uneven surfaces.

[0013] The beneficial effects of this utility model are: the anti-wrinkle and anti-mark cardboard lining uses a combination of cardboard and grooves to create grooves in the eyelet reinforcement area and tongue area of ​​the corresponding shoe. When the cardboard is hot-pressed, the grooves provide space for the warped parts of the cardboard and reduce wrinkles caused by the shrinkage of excess cardboard during hot pressing. In addition, the grooves correspond to the harder parts of the shoe upper material, making them less susceptible to deformation from the pressure of the grooves, so as to prevent the grooves from forming depressions or bulges on the shoe upper, which would seriously affect the appearance of the shoe.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so as to provide a clearer understanding of the technical concept claimed by the present invention.

[0019] like Figures 1 to 3 As shown, a type of cardboard liner for enhancing warping, removing marks, and resisting wrinkles includes a cardboard body 1 with a hollow arched structure in the front half of a shoe. The top surface of the cardboard body 1 is provided with grooves 2 or protrusions at the positions corresponding to the eyelet reinforcement area and the tongue area of ​​the shoe to allow the cardboard body 1 to be formed and warped.

[0020] The working principle of the anti-wrinkle and anti-marking cardboard liner described in this utility model is achieved through the cooperation of the cardboard body 1 and the groove 2. Figures 1 to 3As shown, the cardboard body 1 has grooves 2 or protrusions in the eyelet reinforcement area (i.e., the area where the cardboard body bends most and is most prone to wrinkling during thermoforming) and the tongue area of ​​the corresponding shoe. It should be noted that if the shoe upper has rigid materials in other areas besides the eyelet reinforcement area and the tongue area, grooves 2 or protrusions can also be provided in other areas of the corresponding shoe where rigid materials (such as thick hard plastic) are provided. During thermoforming of the cardboard body 1, the grooves 2 or protrusions can provide space for the warped parts of the cardboard body 1. The grooves or protrusions can absorb the bending of the cardboard body at the instep area where the cardboard body is most prone to wrinkling. The material in the wrinkled area is partially removed, thereby eliminating the wrinkles caused by the material in the above-mentioned area of ​​the cardboard body not being able to be sucked away during the hot pressing of the mold. In addition, the groove 2 or protrusion corresponds to the position of the harder part of the shoe upper material, and is not easily deformed by the pressure of the groove 2 or protrusion, so as to avoid the groove 2 or protrusion forming grooves or bulges on the shoe upper, which would seriously affect the appearance of the shoe. Compared with traditional shoe linings, this anti-wrinkle and wrinkle-removing cardboard lining is provided with grooves 2 or protrusions for the cardboard body 1 to be hot pressed, which reduces the wrinkles generated by the cardboard body 1 and avoids forming grooves or bulges on the shoe upper, which would affect the appearance of the shoe.

[0021] Specifically, the groove 2 includes one or more, and the groove 2 is a trapezoidal groove; the protrusion includes one or more, and the protrusion is a trapezoidal ridge, such as... Figure 1 The illustration shows a first embodiment of grooves 2 and protrusions. Three grooves 2 or protrusions are used as examples. During the thermoforming of the cardboard body 1, the grooves 2 or protrusions provide space for the warped portions of the cardboard body 1 and reduce wrinkles caused by the shrinkage of excess cardboard during thermoforming. The grooves 2 or protrusions correspond to the position of the shoe tongue and prevent the formation of grooves or bulges on the shoe surface that would affect the shoe's appearance. There is one or more grooves 2, and each groove 2 is a U-shaped groove. There is one or more protrusions, and each protrusion is a U-shaped ridge, such as... Figure 2 The illustration shows a second embodiment of the groove 2 and protrusion. Two grooves 2 or protrusions are used as examples. During the thermoforming of the cardboard body 1, the protrusions provide space for the warped portions of the cardboard body 1 and reduce wrinkles caused by the shrinkage of excess cardboard during thermoforming. The grooves 2 or protrusions correspond to the position of the shoe tongue and prevent the formation of grooves or bulges on the shoe surface that would affect the shoe's appearance. Multiple grooves 2 are sequentially arranged along the length of the cardboard body 1, and the width of the multiple grooves 2 gradually decreases towards the rear of the cardboard body 1. Similarly, multiple protrusions are sequentially arranged along the length of the cardboard body 1, and the width of the multiple protrusions gradually decreases towards the rear of the cardboard body 1. The gradually decreasing width of the grooves 2 or protrusions corresponds to the shape of the shoe tongue portion, such as... Figure 3The third embodiment shown is a groove 2 and a protrusion. The groove 2 is a corrugated groove with undulating edges, and the protrusion is a corrugated ridge with undulating edges. When the cardboard body 1 is hot-pressed, the groove 2 or the protrusion can provide space for the warped part of the cardboard body 1 during molding and reduce the wrinkles caused by the shrinkage of excess cardboard during hot pressing. The groove 2 or the protrusion corresponds to the position of the shoe tongue and avoids the formation of grooves or bulges on the surface of the shoe, which would affect the appearance of the shoe.
