Abstract
Description
Technical Field
[0001] This utility model relates to a packaging box liner, and more particularly to a one-piece molded paper tray liner. Background Technology
[0002] Plastic materials possess advantages such as light weight, high strength, good impact resistance, transparency, moisture resistance, aesthetic appeal, chemical stability, good toughness, and corrosion resistance. They have widely replaced metals, wood, paper, glass, and leather in the packaging industry, thus playing an irreplaceable role in alleviating resource and energy pressures in my country. However, plastic materials have a fatal weakness: their long natural degradation time, sometimes exceeding 100 years. This non-degradability means that plastic waste persists for a long time, and since it is often discarded after a single use, plastic packaging waste has become an increasingly prominent environmental problem, forming so-called "white pollution" and placing significant pressure on the human environment.
[0003] Bottled medicines (such as oral liquids) typically have an inner liner inside the packaging box to separate and limit the placement of the bottles. Currently, most of these inner liners are made of plastic, which is not only more complex and costly to manufacture, but also difficult to degrade and environmentally unfriendly. Utility Model Content
[0004] The purpose of this invention is to overcome the existing defects and provide a one-piece molded paper tray liner, which solves the problems of complex production process and environmental unfriendliness of the current packaging box liners made of plastic.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0006] A one-piece molded paper tray liner includes a cardboard body. Each of the four sides of the cardboard body has horizontally extending outer baffles. Each outer baffle can be folded upwards to be perpendicular to the cardboard body. The outer baffles are connected end-to-end in the horizontal direction and together with the cardboard body to form a storage space. Inner partitions are cut at equal intervals on the cardboard body. The same side of each inner partition in its arrangement direction is connected to the cardboard body as a bottom edge. The other three sides of each inner partition are separated from the cardboard body by through-cuts. Each inner partition can be folded upwards along its bottom edge to be perpendicular to the cardboard body. Storage grooves are formed between adjacent inner partitions and between the outermost inner partition and the outer baffles.
[0007] Furthermore, a first crease is provided at the connection between each of the outer baffles and the cardboard body, and each of the outer baffles can be folded upward along the first crease.
[0008] Furthermore, a second crease is provided at each of the bottom edges.
[0009] Furthermore, each of the two opposing outer baffles is provided with an outwardly extending adhesive plate at its horizontal ends, and a third crease is provided at the connection between the adhesive plate and the outer baffle.
[0010] Furthermore, the side of the inner partition plate opposite to the bottom edge is the top edge, and the middle part of the top edge is higher than the two ends, that is, the inner partition plate as a whole is convex.
[0011] This utility model discloses a one-piece molded paper tray liner, which is made of a single piece of cardboard, and then folded and glued to form the tray. The production process is simple and the production cost is low. It replaces the traditional plastic liner and eliminates the problems of plastic liner being difficult to degrade and not environmentally friendly. Attached Figure Description
[0012] The accompanying drawings are provided to further illustrate the present invention and form part of the specification. They are used together with the embodiments of the present invention to explain the present invention, but do not constitute a limitation thereof. In the drawings:
[0013] Figure 1 This is a schematic diagram of the present invention before folding and bonding;
[0014] Figure 2 This is a schematic diagram of the present invention after folding and gluing. Detailed Implementation
[0015] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0016] like Figure 1 , 2 As shown, a one-piece molded paper tray liner includes a cardboard body 1. The four sides of the cardboard body 1 are respectively provided with horizontally extending outer baffles 2. Each outer baffle 2 can be folded upward to be perpendicular to the cardboard body 1. The outer baffles 2 are connected end to end in the horizontal direction and together with the cardboard body 1 to form a storage space. Inner partitions 3 are cut at equal intervals on the cardboard body 1. The same side of each inner partition 3 in the arrangement direction is connected to the cardboard body 1 as the bottom edge. The other three sides of each inner partition 3 are separated from the cardboard body 1 by through-cutting. Each inner partition 3 can be folded upward along the bottom edge to be perpendicular to the cardboard body 1. A storage groove is formed between adjacent inner partitions 3 and between the outermost inner partition 3 and the outer baffles 2.
[0017] Each outer baffle 2 has a first crease at the connection point with the cardboard body 1, and each outer baffle 2 can be folded upwards along the first crease. Each bottom edge has a second crease, and each inner partition 3 can be folded upwards along the second crease.
[0018] Two opposing outer baffles 2 are provided with outwardly extending adhesive plates 4 at their horizontal ends, and a third crease is provided at the connection between the adhesive plate 4 and the outer baffle 2.
[0019] Working principle:
[0020] 1. Using a single piece of cardboard as raw material, cut and press it to obtain the cardboard body 1, outer baffle 2, inner partition 3, gluing board 4, and various creases;
[0021] 2. Fold the adhesive board 4 upwards along the third crease until it is perpendicular to the outer baffle 2, and apply glue to the outer side of the adhesive board 4;
[0022] 3. First, fold the two outer baffles 2 with the adhesive board 4 upward along the first crease until they are perpendicular to the cardboard body 1. Then, fold the other two outer baffles 2 upward along the first crease until they are perpendicular to the cardboard body 1. At the same time, glue the adhesive board 4 to the two outer baffles 2.
[0023] 4. Fold the inner partition 3 upwards along the second crease until it is perpendicular to the cardboard body 1. The inner lining of the paper tray is now formed and can be used to hold medicine bottles, batteries and other items before being placed into the packaging box.
[0024] The creases throughout the design reduce the difficulty of folding and ensure the quality of folding.
[0025] The edge opposite the bottom edge of the inner partition 3 is the top edge. The middle of the top edge is higher than the two ends, meaning the inner partition 3 is convex in shape. The middle of the top edge ensures the isolation between the storage compartments, while the two ends of the top edge facilitate the removal of items from the storage compartments.
[0026] This utility model discloses a one-piece molded paper tray liner, which is made of a single piece of cardboard, and then folded and glued to form the tray. The production process is simple and the production cost is low. It replaces the traditional plastic liner and eliminates the problems of plastic liner being difficult to degrade and not environmentally friendly.
[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
