The terms "first" and "second" are only for descriptive convenience and have no other directional meaning, and should not be construed as limiting the present utility model.

[0046] It should be noted that similar reference numerals represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it may not be further defined and explained in subsequent drawings.

[0047] As Figure 1-2 shown, this embodiment provides a packaging structure of boxed pull-out wound terry cloth, which includes a packaging box 1, two thin-walled support members 2, and a tearable towel roll 3. The support member 2 is obtained by thermoforming a thin-walled plastic sheet or is formed by pulp molding. It has the characteristics of convenient processing, high processing efficiency, low cost, and light weight, and is easier to degrade and more environmentally friendly.

[0048] Specifically, as Figure 1-6As shown, the support member 2 includes a bottom wall 21 and side support walls 22 extending toward the first side around the bottom wall 21. A positioning convex portion 23 that protrudes toward the first side and has a circular contour is provided in the middle of the bottom wall 21. The packaging box 1 includes two end walls 11 and a box peripheral wall 12, and the support members 2 are respectively provided inside the end walls 11; the bottom wall 21 abuts against the inner surface of the end wall 11, and the side support walls 22 extend toward the axis side of the tearable towel roll 3 and cooperate with the inner contour of the box peripheral wall 12 to play a supporting role.

[0049] The tearable towel roll 3 is axially arranged between the two support members 2, and the positioning convex portion 23 extends into the core 31 of the tearable towel roll 3 to play an internal support role. A strip-shaped opening 13 parallel to the axis of the tearable towel is provided on the box peripheral wall 12 of the packaging box 1, and the tearable towel roll 3 can rotate around the positioning convex portion 23 to realize the gradual conveyance of the free end S of the towel from the strip-shaped opening 13.

[0050] The tearable towel roll rotates with its core 31 and the positioning convex portion 23 as the axis, and is kept at a certain distance from the inner wall of the packaging box 1 under the support of the positioning convex portion 23, reducing and even eliminating the friction between the two, making the pulling and tearing process of the tearable towel cloth smoother. The packaging box and the support member can be reused. After the tearable towel roll is used up, only need to reload another tearable towel roll as a replacement part, which is not only simple to replace, but also more environmentally friendly.

[0051] Further, the support member 2 is formed by thermoforming a plastic sheet with a thickness range of 0.03 - 0.08 mm; the side support walls 22 are continuous annular walls, thereby improving the lateral support performance and the assembly stability of the support member 2.

[0052] It should be recognized that the support member 2 not only provides rotational support for the towel roll, but also can strengthen the ends of the packaging box 1, improve the strength of the whole package, and also play a certain waterproof role for the ends and side edges of the package, avoiding the dampness and soiling of the towel roll after the end of the packaging box 1 gets damp.

[0053] Due to the lubricity of the surface of the bottom wall 21 of the support member 2 during the thermoforming process, its surface can avoid damaging the towel roll and is more conducive to the rotation of the towel roll.

[0054] As Figure 4-7 shown, the annular wall of the support member 2 forms a receiving groove, and the end of the tearable towel roll 3 is located in the receiving groove, which can also prevent the end of the towel roll from approaching the inner surface of the box peripheral wall 12 of the packaging box 1 too closely, reducing the adverse effect of the inner surface of the box peripheral wall 12 of the packaging box 1 with higher surface roughness on the rotation of the towel roll.

[0055] The two end walls 11 of the packaging box 1 are provided in the form of an open box cover, and after the tearable towel roll 3 is loaded into the inner cavity of the packaging box 1, the support member 2 is inserted into the packaging box 1 and fits with the end of the tearable towel roll 3, and then the box cover forming the end wall is closed, so that the assembly is more convenient.

[0056] Furthermore, the inner cavity of the packaging box 1 is rectangular in cross section, and the annular wall of the support member 2 is adapted to the inner cavity of the packaging box 1 and elastically stuck in the box peripheral wall 12. The adaptation and limitation of the rectangular structure also prevents the support member 2 from being driven when the towel roll rotates.

[0057] like Figure 4 As shown, the strip opening 13 is located on a side wall of the packaging box 1 and deviates from the center line of the side wall, so that the packaging structure has different usage states and is suitable for different usage scenarios.

[0058] The usage status includes Figure 1 The end walls 11 are arranged vertically in the first state, as shown in FIG. Figure 3 The end walls 11 are arranged horizontally on the left and right sides and the side walls with strip openings 13 are facing upwards in the second state and as shown in FIG. Figure 2 The end walls 11 are arranged horizontally on the left and right sides, and the side walls with the strip openings 13 face forward and the strip openings 13 are located at a lower position in the third state. Figure 2 As shown, the second state is suitable for the scenario where the packaging structure is placed on a support surface M such as a desktop, and the user takes a towel from it. Figure 2 As shown, the third state is applicable to the scenario where the packaging structure is placed on a bracket N similar to a wall T, and the user draws the towel sideways downward. Figure 1 As shown, the first state is suitable for a scenario in which the user pulls the towel upward, downward, or flatly from the front after placing it on the support surface M.

[0059] like Figure 4 As shown, preferably, the packaging box 1 is a paper box with flip-openings on both sides, so as to facilitate the assembly of the towel roll and the support 2. Preferably, circular expansions e are provided at both ends of the strip-shaped opening 13, and a semicircular expansion f is provided on one side of the strip-shaped opening 13. The circular expansions e at the ends can prevent the towel from being scratched against the edge of the opening when it is pulled out and inserted into the strip-shaped opening 13, thereby making the pulling and pulling smoother.

[0060] like Figure 6-8 As shown, a circular groove depression 24 is formed at the corresponding position of the positioning protrusion 23 on the side away from the tearable towel roll 3; the bottom wall 21 is provided with a plurality of annular convex ribs 25 protruding toward the axial side of the tearable towel roll 3 and coaxial with the positioning protrusion 23, and an annular depression 26 is formed on the side away from the tearable towel roll 3. The provision of the annular convex ribs 25 enhances the strength of the bottom wall 21, so that the supporting performance of the entire support member 2 is better.

[0061] The annular rib 25 presses against the end of the tearable towel roll 3, which can increase friction, making the rotation of the towel roll have appropriate damping and preventing the towel from being pulled out excessively. Moreover, the annular rib 25 can also play a certain limiting role for the towel roll, improving the problem of the towel being loose and guiding the rotation.

[0062] As Figure 7 shown, the cross-section of the surface contour of the annular rib 25 is arc-shaped, thus avoiding damage to the end face of the towel roll and also avoiding the rotation obstacle caused by pulling the edge of the towel due to the sharp corner.

[0063] As Figure 9 shown, in another embodiment, a flanging 27 that bends outward is provided on the outer edge of the annular wall, and the width of the flanging 27 is less than 1.5 mm. Due to its small width, this flanging 27 has good flexible deformation ability and can support on the inner surface of the peripheral wall 12 of the box after deformation, thereby improving the position limitation between the support member 2 and the packaging box 1 and making the assembly more stable.

[0064] The above introduces the support member and the packaging structure of the boxed pull-out winding type towel cloth provided by the present utility model. Specific examples are used in this article to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the present utility model and its core idea. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and modifications can be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
