Description

Technical Field

[0001] This utility model relates to the field of metal packaging box technology, and in particular to a metal box for compressed candy with a sliding opening and closing structure. Background Technology

[0002] As a common food form (such as lozenges, nutritional supplement tablets, etc.), the packaging of compressed candies needs to take into account food protection (moisture-proof, oxidation-proof, pollution-proof), ease of use, and appearance. For example, the sliding-opening compressed candy box disclosed in Chinese invention patent No. 2018116539104 includes a bottom cover, a sealing element, and a top cover. The sealing element and the top cover are sequentially fastened to the bottom cover. The bottom cover is provided with a receiving groove, and a candy chamber for accommodating compressed candies is formed between the sealing element and the bottom cover. It also includes an outlet baffle and a sliding element that are connected to each other. The sealing element is provided with a first candy outlet hole and a first sliding groove. The top cover is provided with a corresponding second candy outlet hole and a second sliding groove. The outlet baffle is fastened to the first candy outlet hole and slidably disposed in the first sliding groove. The sliding element is slidably connected to the second sliding groove. The outlet baffle slides along the first sliding groove, causing the sliding element to slide along the second sliding groove. A switch assembly is provided between the sealing baffle and the sliding element.

[0003] The aforementioned candy box has a relatively complex structure and a complex production process. The assembly process is time-consuming, resulting in high production costs. Moreover, assembly requires highly skilled production staff, which compresses the already limited profit margins in the candy box industry, thus necessitating improvements. Summary of the Invention

[0004] This utility model aims to solve one of the technical problems existing in the prior art.

[0005] This application provides a metal box for compressed candy with a sliding opening and closing structure, comprising an upper box body and a lower box body that are positioned opposite each other. The box body and the lower box body are characterized by an integrally injection-molded intermediate component. The intermediate component is installed at the opening of the lower box body via an interference fit, and the upper box body is installed on the side of the intermediate component away from the lower box body via an interference fit. After installation, the upper box body can slide laterally relative to the intermediate component. Both the upper and lower box bodies are made of metal, while the intermediate component is made of plastic. The intermediate component has a through hole for the compressed candy to pass through.

[0006] Preferably, the upper and lower box bodies each have an inwardly rolled edge at their openings. The injection-molded intermediate part includes an intermediate plate and an annular protrusion connected to the lower surface of the intermediate plate. The intermediate plate forms a trapezoidal protrusion structure with a trapezoidal cross-section, extending upward from the left to the right from the upper surface. Upper locking blocks at the same height are provided on the front and rear sides of the trapezoidal protrusion structure to engage with the edge of the upper box body. The through hole is located on the left side of the trapezoidal protrusion structure. Lower locking blocks at the four corners of the intermediate plate on the outer wall of the annular protrusion are provided to engage with the edge of the lower box body. The four lower locking blocks are at the same horizontal height, with each pair located on the front and rear sides of the annular protrusion.

[0007] Preferably, the lateral length of the upper block is greater than half the lateral length of the trapezoidal protrusion structure.

[0008] Preferably, the lower surface of the trapezoidal protrusion structure is provided with a trapezoidal groove that matches its shape.

[0009] Preferably, the lower surface of the annular protrusion has upward notches between the four corners, and the cross-section of the four corners between the four notches is L-shaped.

[0010] Preferably, the top of the trapezoidal protrusion structure is further provided with a top small trapezoidal protrusion layer, the upper surface height of the top small trapezoidal protrusion layer is greater than the height of the top of the trapezoidal protrusion structure, and the trapezoidal height of the top small trapezoidal protrusion layer is less than half of the trapezoidal height of the trapezoidal protrusion structure.

[0011] Preferably, the lower surface of the top trapezoidal protrusion layer is provided with a small trapezoidal groove that matches its shape.

[0012] Preferably, the through hole is located on the left front side of the trapezoidal protrusion structure.

[0013] The aforementioned metal box for compressed candy with a sliding opening and closing structure addresses three core pain points of existing sliding candy boxes: complex structure and high cost, difficult assembly, and difficulty in balancing protection and sliding performance. It achieves comprehensive advantages of low-cost production, convenient assembly, high protection, and smooth use. It can be widely adapted to various products such as regular compressed candy and sensitive nutritional tablets, and is especially suitable for the large-scale production needs of mid-to-high-end food packaging.

[0021] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0022] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0023] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific examples and application scenarios.

[0024] Example 1:

[0025] like Figures 1-6As shown, a metal box for compressed candy with a sliding opening and closing structure includes an upper box body 1 and a lower box body 2 that are opposite each other. In a specific embodiment of this utility model, an integrally injection-molded intermediate part 3 is provided between the upper box body 1 and the lower box body 2. The injection-molded intermediate part 3 is installed at the opening of the lower box body 2 by interference fit. The upper box body 1 is installed on the side of the injection-molded intermediate part 3 away from the lower box body 2 by interference fit. After installation, the upper box body 1 can slide laterally relative to the injection-molded intermediate part 3. The upper box body 1 and the lower box body 2 are both made of metal, and the injection-molded intermediate part 3 is made of plastic. The injection-molded intermediate part 3 has a through hole 4 for the compressed candy to pass through.

[0026] Existing sliding candy boxes require multiple components (such as seals, outlet baffles, sliders, and switch components as described in the background technology). This application integrates three major functions—sealing, sliding guidance, and through-hole opening / closing—through an "integrated injection-molded intermediate component 3," significantly reducing the number of parts compared to existing technologies. The integrated injection molding process eliminates the need for separate processing of multiple parts (such as cutting and grinding). The injection-molded intermediate component 3 is formed in a single injection molding process, shortening the processing cycle and significantly reducing production time and costs. The upper box body 1 and lower box body 2 are made of metal, offering superior moisture resistance, oxidation resistance, and impact resistance compared to existing all-plastic sliding boxes. The metal box body blocks external moisture and oxygen intrusion, extending the shelf life of compressed candies (such as sensitive compressed candies containing probiotics and vitamins). Simultaneously, the gloss and hardness of the metal material enhance the product's appearance and texture, meeting the packaging needs of mid-to-high-end compressed candies. The injection-molded intermediate part 3 is made of plastic. Utilizing the elasticity and low friction characteristics of plastic, it achieves a tight fit with the metal box body through interference fit (avoiding moisture leakage through gaps) and ensures smooth lateral sliding of the upper box body 1.

[0027] Example 2:

[0028] The difference from Embodiment 1 is that, in addition to including the structural features of the aforementioned embodiments, in this specific embodiment of the present invention, the upper box body 1 and the lower box body 2 are respectively provided with an inwardly rolled edge 5 at their openings. The injection-molded intermediate part 3 includes an intermediate plate 31 and an annular protrusion 32 connected to the lower surface of the intermediate plate 31. The intermediate plate 31 forms a trapezoidal protrusion structure 33 with a trapezoidal cross-section, which is raised from the left to the right from the upper surface. The trapezoidal protrusion structure 33 has upper locking blocks 34 at the same height on both the front and rear sides for engaging with the edge 5 of the upper box body 1. The through hole 4 is located on the left side of the trapezoidal protrusion structure 33. The annular protrusion 32 is provided on the outer wall of the intermediate plate 31 at the four corners, and lower locking blocks 35 are respectively provided for engaging with the edge 5 of the lower box body 2. The four lower locking blocks 35 are at the same horizontal height, and each pair is located on the front and rear sides of the annular protrusion 32.

[0029] The upper box 1, lower box 2, and injection-molded intermediate part 3 are all assembled by interference fit, without the need for additional fasteners (such as screws, clips) or professional assembly tools: the inward rolled edge 5 of the lower box 2 directly engages with the lower locking block 35 of the injection-molded intermediate part 3. During assembly, simply align the injection-molded intermediate part 3 with the opening of the lower box 2 and press it down. Since the injection-molded intermediate part 3 is made of plastic, it will deform slightly. The upper box 1 and lower box 2 are both made of metal, which ensures structural strength. During assembly, the plastic part located in the middle deforms independently. The inward rolled edge 5 of the upper box 1 is adapted to the upper locking block 34 of the injection-molded intermediate part 3. Pressing down and then pushing laterally into place completes the pressing and sliding assembly.

[0030] The entire assembly process does not require professional staff; ordinary workers can operate it after simple training. The assembly efficiency is increased several times over the existing technology, directly reducing labor costs and assembly defect rate (existing technology is prone to assembly misalignment due to the cooperation of multiple components).

[0031] In a specific embodiment of this utility model, the lateral length of the upper locking block 34 is greater than half the lateral length of the trapezoidal protrusion structure 33.

[0032] The upper locking block 34 (horizontal length > 1 / 2 of the trapezoidal protrusion structure 33) engages with the inward rolled edge 5 of the upper box body 1. The trapezoidal protrusion structure 33 restricts the lateral sliding stroke of the upper box body 1, preventing excessive sliding and detachment. The upper locking block 34, in conjunction with the inward rolled edge 5 of the upper box body 1, provides vertical positioning. The lower locking block 35 (symmetrically distributed at the four corners) engages with the inward rolled edge 5 of the lower box body 2, and, in conjunction with the annular protrusion 32, ensures that the injection-molded intermediate part 3 and the lower box body 2 are assembled without wobbling.

[0033] In a specific embodiment of this utility model, the lower surface of the trapezoidal protrusion structure 33 is provided with a trapezoidal groove 36 that matches its shape. This is used to reduce costs and provide greater storage space.

[0034] In a specific embodiment of this utility model, upward-facing notches 37 are provided between the four corners of the lower surface of the annular protrusion 32, and the cross-sections of the four corners between the four notches 37 are L-shaped. This provides a certain deformation space for the injection-molded intermediate part 3 to be installed into the lower box 2 (facilitating interference fit assembly), avoids plastic cracking caused by stress concentration at the four corners, extends the service life of the injection-molded intermediate part 3, and reduces material costs and the overall weight of the product (making it easy to carry).

[0035] In a specific embodiment of this utility model, the top of the trapezoidal protrusion structure 33 is further provided with a top small trapezoidal protrusion layer 38. The height of the upper surface of the top small trapezoidal protrusion layer 38 is greater than the height of the top of the trapezoidal protrusion structure 33, and the trapezoidal height of the top small trapezoidal protrusion layer 38 is less than half of the trapezoidal height of the trapezoidal protrusion structure 33.

[0036] The small trapezoidal protrusion layer 38 at the top further optimizes the sliding guide, reduces the offset when the upper box 1 slides laterally, and ensures smooth operation even after long-term use. It also provides vertical force deformation to cooperate with the upper latch 34 and the inward rolled edge 5 of the upper box 1, making the assembly of the upper box 1 and the injection-molded intermediate part 3 more secure. This also makes the sliding of the upper box 1 feel better and prevents it from opening easily. At the same time, the trapezoidal height of the small trapezoidal protrusion layer 38 is small (less than 1 / 2 of the trapezoidal protrusion structure 33), which reduces sliding resistance and further optimizes the feel.

[0037] In a specific embodiment of this utility model, the lower surface of the top small trapezoidal protrusion layer 38 is provided with a small trapezoidal groove 39 that matches its shape.

[0038] This is intended to further reduce costs and provide some storage space. It also aims to reduce material costs and the overall weight of the product (making it easier to carry).

[0039] Example 3

[0040] The difference from Embodiment 1 is that, in addition to including the structural features of the aforementioned embodiments, in the specific embodiments of this utility model, such as... Figure 4 and Figure 6 As shown, the through hole 4 is located on the left front side of the trapezoidal protrusion structure 33.

[0041] The through-hole 4 of the injection-molded intermediate part 3 (located on the left / front left side of the trapezoidal protrusion 33) precisely matches the sliding stroke of the upper box 1: when the upper box 1 slides to the right, the through-hole 4 is fully exposed, allowing one or two compressed candies to be removed at a time (the through-hole size is adapted to the diameter of regular compressed candies to prevent multiple candies from falling out); when sliding to the left, the inner wall of the upper box 1 completely covers the through-hole 4, achieving a sealed closure. The entire opening and closing process only requires a single-handed horizontal push, making the operation simpler than the existing structure that requires "pressing + sliding," and is especially suitable for children, the elderly, and other groups.

[0042] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. Furthermore, it should be noted that the scope of the methods and apparatuses in the embodiments of this application is not limited to performing functions in the order shown or discussed, but may also include performing functions substantially simultaneously or in the reverse order, depending on the functions involved. For example, the described methods may be performed in a different order than described, and various steps may be added, omitted, or combined. Additionally, features described with reference to certain examples may be combined in other examples.

[0043] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
