Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging box technology, and is mainly used for display packaging boxes for fruits, vegetables and food. Specifically, it is a self-sealing lid for open boxes. Background Technology
[0002] In the current fruit market, a common packaging phenomenon exists. Many fruit varieties, such as blueberries, grapes, tomatoes, and Shine Muscat grapes, after undergoing a series of processes including careful harvesting, sorting, and packing at the plantation, are mostly packaged in open-top boxes. The popularity of this packaging method is primarily based on its unique advantages in the end-market sales stage. When these fruits are transported to supermarkets and other sales venues, open-top boxes can be easily stacked and displayed. Their open design allows the fruit to be presented to consumers without any obstruction, greatly enhancing the product's display effect and quickly attracting consumers' attention, stimulating their desire to buy. Furthermore, for some fruits with extremely high requirements for freshness and requiring cold chain transportation, open-top boxes play an irreplaceable role. During cold chain transportation, cold air can circulate freely inside the open-top box, achieving ideal preservation effects, maximizing the fruit's freshness period, and ensuring that consumers can enjoy the original, fresh flavor of the fruit. Even for fruits transported at room temperature, open-top boxes offer a significant advantage in ventilation compared to other packaging methods such as top-and-bottom boxes, corrugated cardboard boxes, and integrated boxes. Good ventilation effectively prevents spoilage and rot caused by poor air circulation during transportation and storage, providing strong protection for the fruit's quality. Open-top box packaging also excels in cost control. Compared to other more complex and sophisticated packaging types, the manufacturing process of open-top boxes is relatively simple, using more basic materials. This allows for effective cost reduction in large-scale production, making them more price-competitive.
[0003] However, open-top box packaging is not without its drawbacks in the end-sales stage, exhibiting several undeniable shortcomings. When customers want to purchase entire boxes of fruit as gifts, the limitations of open-top boxes become glaringly apparent. To meet the demand for full-box purchases or gift-giving, sales staff often need to take additional measures. A common practice is to re-lid the open box, usually by using a different box lid. However, this method doesn't adequately address aesthetics and compatibility. Furthermore, additional carrying bags are needed for easier handling, undoubtedly increasing sales costs and workload. Simultaneously, the overall harmony and aesthetics of the original open box are significantly diminished after adding a lid and bag, appearing rather awkward and rudimentary. Another approach is to directly repackage the fruit from the open box into a dedicated gift box. While this method enhances the fruit's perceived value and image as a gift, it introduces a series of new problems. First, gift boxes are typically more expensive, leading to a substantial increase in sales costs, which in turn necessitates a corresponding increase in the fruit's price, ultimately borne by the consumer. Secondly, the process of repackaging fruit from open boxes to gift boxes consumes a significant amount of time and effort for sales staff, severely impacting sales efficiency, especially during peak sales seasons. Furthermore, the original open boxes are discarded after repackaging, resulting in a substantial waste of resources, which contradicts current advocacy for environmental protection and conservation.
[0004] Another simpler and more direct method is to secure the open box with a rope tied in a cross shape for easy carrying. However, this method is extremely inconvenient in practice. When customers carry it horizontally, the rope's limited and unstable points of contact can easily cause their hands to get caught, and the box is difficult to balance, requiring extra caution while walking, as the fruit may easily spill. From an aesthetic point of view, an open box tied with rope looks very simple and rough, lacking any beauty and seriously affecting the overall image of the product. When given as a gift, this packaging method fails to reflect the intended quality and sincerity of the gift, greatly diminishing its effectiveness and failing to meet consumers' demands for exquisite and elegant gifts in social etiquette. Summary of the Invention
[0005] To address the shortcomings and defects of the existing technology, the inventors have innovatively designed and improved a self-sealing lid for open-top boxes that is more environmentally friendly, more economical, reduces resource duplication and waste, and can be flexibly matched to customer requirements at the point of sale, reducing the cost for merchants to remake gift boxes. Specifically, this utility model is implemented as follows:
[0006] A self-sealing lid for an open box, used for assembly with the open box, includes: a lid body having a plurality of transverse pre-compression creases and vertical pre-compression creases for covering and enclosing the front opening area of the open box; end heads located at both ends of the lid body in the length direction, formed by transverse pre-compression creases, the end heads being able to fit against the end face of the open box; side portions located on both sides of the lid body in the width direction, formed by vertical pre-compression creases, for attaching to or inserting into the side of the open box from the outside or inside to position the lid body; and adhesive portions, at least at one end of the lid body, or at opposite ends, for bonding and fixing to the side wall, end wall, or bottom of the open box to position and fix the lid body.
[0007] Furthermore, the transverse pre-compression crease includes two sets of first transverse pre-compression creases and second transverse pre-compression creases. An adhesive portion is formed between the first transverse pre-compression crease and the end edge. An end head is formed between the first transverse pre-compression crease and the second transverse pre-compression crease. A side portion is formed between the vertical pre-compression crease and the side edge. The two second transverse pre-compression creases and the two vertical pre-compression creases constitute the front area of the cover body. The adhesive portion is attached to the bottom surface of the open box end.
[0008] Furthermore, a transversely penetrating zipper-like tear strip is pre-pressed onto the end head, which can be torn to cut off the end head for opening the cover.
[0009] Furthermore, at least one perforated display window is provided on the front area of the cover body. The perforated display window is in a perforated state, or a transparent material is glued or pre-glued to the inner edge of the perforated display window.
[0010] Furthermore, the end head is pre-pressed with two hook holes for inserting handle lugs, and the open box also has the same hook holes at the same position on the same side of the end head, so that the lugs at both ends of the handle can pass through the two sets of hook holes at once to install the handle.
[0011] Furthermore, the width and length of the end head are adapted to the width and length of the end face of the open box; the dimensions of the front area of the cover body are adapted to the dimensions of the front of the open box.
[0012] Furthermore, the cover body is integrally molded from paper material or PVC plastic sheet, and the outer surface is printed with decorative or promotional patterns, textures, text, trademark graphics or LOGO by means of printing, lamination, hot stamping, embossing or partial UV printing.
[0013] Furthermore, the adhesive part is disposed on the inner side of the end head at one or both ends; or the adhesive part is disposed on the inner side of the side portion on one or both sides; or the adhesive part is disposed on the inner side of the end head at both ends and the side portion on both sides; the adhesive part is double-sided adhesive, pre-adhesive, and can be used immediately by tearing it off.
[0014] The working principle of this utility model is as follows: First, by setting horizontal and vertical pre-compression creases on the lid body, it can be folded conveniently and quickly during use. The pre-made dimensions of the front area of the lid body are adapted to the shape and size of the open box. An adhesive portion is formed between the first transverse pre-compression crease and the end edge. This adhesive portion is used to bond the lid to the bottom surface of the open box, thus fixing the lid to one end of the open box. An end head is formed between the first and second transverse pre-compression creases, and a side portion is formed between the vertical pre-compression crease and the side edge. The end head fits against the end face of the open box, and the side portion is attached from the outside or inserted from the inside to help position the lid body, ensuring that the lid can stably cover the front opening area of the open box. Then, the lid body is placed on the open box, and the other end head also fits against the other end face of the open box. After peeling off the paper covering of the other adhesive portion, it is bonded to the bottom surface of the other end of the open box. At this point, the self-sealing lid is combined with the open box, effectively covering the fruit inside. Finally, the handle is inserted through the buckle hole on the end head and the buckle hole on the end of the open box to complete the assembly process. Consumers can easily open the box by tearing the zipper-like tear strip at the top. A perforated display window on the front of the lid allows the contents to be shown without opening the lid; a transparent window can also provide protection. Furthermore, the lid is made of paper or directly molded from a single piece of PVC plastic, offering good workability and economy. The outer surface can be printed with various decorative or promotional content, enhancing the product image and commercial value. This self-sealing lid design provides the open box with excellent sealing and display capabilities, while also improving aesthetics and portability, effectively addressing many shortcomings of traditional open boxes in relevant applications.
[0015] The beneficial technical effects of this utility model are as follows:
[0016] (1) This invention solves the packaging problem of open boxes when sold in bulk at the terminal. By setting horizontal and vertical pre-compression creases, the lid can be folded conveniently and quickly during use. It is fixed to the bottom of the open box by adhesive parts, and the side parts are attached from the outside or inserted from the inside, which can stably position and fix the lid body from all directions, ensuring that the lid can cover the front opening area of the open box well, and achieving rapid adaptability packaging. The integrated lid design of this invention is made of cardboard or PVC sheet, which is inexpensive and space-saving, and is convenient for storage, transportation and retail. The quick-installation design with handles also makes it convenient to carry and retail. There is no need to find a separate cardboard lid. Compared with cardboard lids, this lid is cheaper, uses less material, is more environmentally friendly and economical, reduces resource duplication and waste, is easy to operate, has fewer folding steps than cardboard lids, occupies less storage space than cardboard lids, is lighter and easier to operate, and reduces the cost for merchants to remake gift boxes.
[0017] (2) A horizontally through zipper-like tear strip is pre-pressed at the end head. When consumers open the package, they only need to tear the zipper-like tear strip to cut off the end head, which can realize convenient opening operation, which is both ceremonial and easy to operate.
[0018] (3) At least one perforated display window is opened on the front area of the lid body, or a transparent PVC sheet is used directly as the lid body, so that the contents of the open box can be displayed without opening the lid body, making it easy for consumers to intuitively understand the contents. Alternatively, a transparent material window can be glued or pre-glued to the inner edge of the perforated display window, which can also play a protective role while displaying the contents, thus improving the display and aesthetics of the product. The lid body is made of paper material or PVC plastic sheet in one piece. The outer surface can be printed with decorative or promotional patterns, textures, text, trademark graphics or LOGO through printing, lamination, hot stamping, embossing or partial UV printing, which can improve the aesthetics of the product and create a good product image. This is very beneficial for whole box sales and application scenarios such as gifts, and also helps to improve commercial value.
[0019] Overall, this self-sealing lid allows open boxes to offer excellent sealing and display properties when sold in bulk or as gifts, while also enhancing aesthetics and portability. It effectively addresses many shortcomings of traditional open boxes in relevant application scenarios, significantly improving overall performance and offering good practicality and economy.
