Description

Technical Field

[0001] This utility model relates to the field of packaging technology, specifically to a paper-plastic inner tray. Background Technology

[0002] In existing technologies, paper-plastic inner trays used to store chargers and data cables typically employ a simple dual-cavity structure design. This means the inner tray itself has only two independent cavities: one for the charging adapter and the other for the data cable. This traditional structure has significant drawbacks: Firstly, because the data cable and charging adapter are placed in separate cavities, the data cable lacks effective restraint within the cavities. During storage and transportation, it is prone to free movement due to vibration, causing frequent friction between the cable and the cavity walls. This not only easily leads to wear and tear on the cable sheath but may also generate noise due to the movement. Secondly, limited by the cavity's space, the data cable must be coiled into a small loop to fit inside. This small bending radius causes the cable to be in a state of excessive bending for extended periods, frequently resulting in tangled and knotted cables that require time to untangle before normal use, significantly reducing ease of use. Furthermore, it may lead to fatigue fracture of the internal copper wires or aging and cracking of the outer sheath, affecting the data cable's lifespan. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a paper-plastic inner tray.

[0008] Preferably, the bottom of the second groove is provided with a protrusion, which is arranged along the width direction of the second groove.

[0009] The beneficial effects of this utility model are: the surrounding grooves on the outside of the first and second cavities increase the bending radius of the wire, reduce the degree of deformation of the data cable, avoid knotting during use, and also reduce the risk of aging and breakage caused by excessive bending, thus extending the service life; the stepped depth structure of the first and second grooves is adapted to the stacking height of the wires, making the overall storage flat and compact, and improving the neatness of the packaging.

[0013] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0014] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0015] The technical solution of this utility model will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] See Figure 1 As shown, the structure of this utility model is as follows: a paper-plastic inner tray, including an inner tray body 1, on which a first cavity 2 is integrally formed. The first cavity 2 is used to accurately accommodate the charger body, and the stable positioning of the charger body is achieved through shape matching, preventing shaking during storage or transportation. A second cavity 3 is provided at one end of the first cavity 2, which is used to accommodate the charger plug. A receiving groove 4 is arranged around the outer side of the first cavity 2 and the second cavity 3. The receiving groove 4 provides winding space for the data cable. The winding path of the cable is constrained by the contour of the groove. The large-diameter winding space formed by the receiving groove 4 around the cavity can reduce the bending degree of the data cable. The larger the diameter, the larger the bending radius of the cable, reducing the risk of deformation and breakage caused by long-term excessive bending, and extending the service life of the data cable. At the same time, the cooperation between the groove and the recess makes the cable winding more regular, avoiding messy winding and making it easier to pick up. For added convenience, the inner tray body 1 is provided with a first groove 5 and a second groove 6. The first groove 5 and the second groove 6 are respectively used to accommodate the two interfaces of the data cable. By inserting the two interfaces of the data cable into the first groove 5 and the second groove 6 respectively, the user can intuitively see the interface type through the transparent outer packaging. The first groove 5 and the second groove 6 are connected to the receiving groove 4 through the corresponding first wire groove 7 and the second wire groove 8 respectively. The bottom of the first groove 5 and the first wire groove 7 are flush with the bottom of the receiving groove 4. The depth of the second groove 6 and the second wire groove 8 is less than that of the first groove 5 and the first wire groove 7. The first groove 5 and the first wire groove 7 cooperate to provide an initial fixing position for one end of the data cable interface. Its flat bottom design provides stacking space for cable winding. The stepped depth difference between the second groove 6 and the second wire groove 8 is adapted to the stacking height after the data cable is wound, so that the end interface remains flat after being inserted.

[0017] like Figure 1 As shown, the inner side of the receiving groove 4 is provided with limiting protrusions 9. Specifically, the two limiting protrusions 9 are arranged opposite each other and extend into the groove from both sides of the inner wall of the receiving groove 4. The height of the limiting protrusions 9 does not exceed the height of the groove opening of the receiving groove 4, which can limit the data cable wound in the receiving groove 4. Through the blocking effect of the limiting protrusions 9 on both sides, the data cable is prevented from coming off the receiving groove 4 during storage or transportation.

[0018] like Figure 1As shown, the first cavity 2 is provided with a retrieval slot 10 at the end away from the second cavity 3. Specifically, when it is necessary to remove the charger, the retrieval slot 10 can form a force fulcrum with the second cavity 3. The user can hold the end of the charger located on the side of the retrieval slot 10 and the plug part on the side of the second cavity 3 with both hands, and can easily remove the charger from the first cavity 2.

[0019] like Figure 1 As shown, one end of the inner tray body 1 is provided with a recess 11. Specifically, one end edge of the inner tray body 1 is formed with an inwardly recessed recess 11. The recess 11 is set independently of the cavity and the receiving groove 4 structure. When the outer packaging is opened, the user can insert his / her finger into the recess 11 and use the force point provided by the recess 11 to easily remove the inner tray body 1 completely from the outer packaging box.

[0020] like Figure 1 As shown, the bottom of the second groove 6 is provided with a protrusion 12. The protrusion 12 is set along the width direction of the second groove 6. Specifically, the protrusion 12 is located in the middle of the bottom of the groove and its height does not exceed the depth of the second groove 6. When it is necessary to remove the data cable interface, press the end of the data cable interface near the data cable. The protrusion 12 forms a lever action as a fulcrum, which can make the other end of the interface naturally lift up, making it easy for the user to quickly remove the data cable.

[0021] In practical use, align the charger body with the first cavity 2 of the inner tray body 1, and insert it vertically after matching the outline of the body with the shape of the cavity until the charger body is completely embedded in the first cavity 2 for stable positioning. At this time, the metal plug of the charger is inserted into the second cavity 3. Then, take one end of the data cable interface, align it with the first groove 5 of the inner tray and press it vertically so that the interface is completely inserted into the first groove 5. The end of the cable is then introduced into the receiving groove 4 through the first cable groove 7. Then, the cable is wound into the receiving groove 4 in an orderly manner, keeping the cable in line with the outline of the groove during the winding process, and naturally stacking it using the large diameter space. When the cable is wound to the end, guide the other end of the data cable interface through the second cable groove 8 to the second groove 6 and press it vertically to insert the interface into the groove. At this time, due to the stepped depth design of the second groove 6 and the second cable groove 8, the end interface is kept at the same height as the cable stacked in the receiving groove 4, completing the overall storage.

[0022] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
