Abstract

A packing box comprises a cylindrical box body (1) which is opened at two ends and box covers (2) which seal the openings at two ends of the box body (1), wherein the edge of at least one opening at two ends of the box body (1) is inwards bent to form a hook buckle. The box cover (2) is a sheet component of which shape is same to the opening of the box body (1), and the edge of the sheet component is bent towards center thereof, wherein the bent edge is buckled with the hook buckle in the box body (1). The packing box avoids wasting energy, provides aesthetic sealing, protects the environment, and effectively improves the production efficiency.

Description

Instruction box

Technical field

[1] The present invention relates to a sealed packaging container, and more particularly to a packaging.

Background technique

[2] The traditional sealed packaging container, especially the cylindrical packaging box, is bent at an angle of 90 degrees inward at the edge of the opening of the box, and the edge of the sheet is placed inside to make the edge fit, and then the heat is applied. The pressing process seals the package; or forms a ring seat at the opening of the box, and then places the edge of the sheet cover on the ring seat and glues to form a sealing structure.

[3] In the above method, if the hot pressing process is used, not only the hot pressing process consumes heat energy, but also energy is wasted, and since the packaging box generally uses more plastic materials, the sealing portion also forms wrinkles due to the hot pressing process. It is not beautiful enough; if glue is used for bonding, not only the additional glue investment is required, but also the bonding process generally needs to be done manually, which is not efficient, resulting in excessive investment of material resources and human resources.

Disclosure of invention

technical problem

[4] In view of this, it is necessary to provide a package that is easy to seal and environmentally friendly.

Technical solution

[5] A package comprising a box body and a lid open at both ends, the lid closing the opening of the box body

An edge of at least one of the two ends of the box body is curled inwardly to form a hook, the lid is a sheet member having the same shape as the opening of the box body, and the edge of the sheet member is curled toward the center, the box The cover is fastened to the hook inside the box body.

[6] The box body and the edge of the lid are crimped and fastened together, which is purely mechanically combined and easy to handle.

[7] In a preferred embodiment, the fastening of the lid to the casing is formed by the edge of the lid being attached to the edge of the opening of the casing and then co-rolling into the casing. The combination of the co-rolls ensures a tight seal.

[8] In a preferred embodiment, the casing or the lid is constructed of two or more layers.

[9] In a preferred embodiment, the box has a wall thickness of 0.05 mm to 1 mm. [10] In a preferred embodiment, the casing has a diameter of from 20 mm to 1000 mm.

[11] In a preferred embodiment, the material produced is phthalate glycol, polycarbonate, polylactic acid, polystyrene, polyethylene, polyvinyl chloride or polypropylene.

[12] Figure 1 is a schematic view of the package;

[13] Figure 2 is a longitudinal sectional view of the package.

[14] Further explanation will be given below with reference to the drawings.

BEST MODE FOR CARRYING OUT THE INVENTION

[15] The process of sealing the box with the edge of the lid and the edge of the opening of the box seals the package, which has the advantages of simple treatment and environmental protection.

[16] Example 1

[17] As shown in Figure 1, it is an overall schematic view of the appearance of the package. The package includes a case 1 and a cover 2, and the case 1 has a cylindrical shape with open ends, and the cover 2 seals the opening at both ends of the case 1.

[18] As shown in Figure 2, is a longitudinal section of the package. The edge of the opening at both ends of the casing 1 is curled inwardly to form a hook 11 which is a circular sheet member whose edge is curled in the center direction, and the lid 2 is located inside the casing 1 with its curled edge and hook 11 buckled. The fastening structure of the cover 2 and the casing 1 can be formed by aligning the edge of the cover 2 with the edge of the opening of the casing 1 and then co-rolling into the casing. In other embodiments, it is also possible to use a hook-and-loop structure at only one end opening and another structure at the other end.

[19] The box can be made transparent, translucent or opaque using different materials depending on the application. The material produced is APET 'mold polyethylene terephthalate PETG, glycol-modified polyethylene terephthalate, GAG, multi layer of PETG or

APET&PETG), polycarbonate (PC), polylactide polymers, high impact polystyrene, polyethylene, polyvinyl chloride (PVC, polyvinyl chloride) ) or polypropylene (PP, polypropylene).

[20] The package in this embodiment can be used in any case where a sealed package is required, and the size of the package depends on the use. The shape may be a circular, elliptical, polygonal or the like suitable for packaging or aesthetic appearance, preferably circular. Too large a package may not achieve the desired effect in the sealing process. Too small a package is not widely used, and there should be a better sealing method. Therefore, it is preferable that the size of the package is the diameter of the case. For boxes from 20mm to 1000mm, the height depends on the specific capacity. For example, the packaging box for decoration, the box body is made transparent, and the interior is provided with small ornaments, which can be placed on the desk for decoration, generally not too large, and the diameter is about 50 mm.

[21] Example 2

[22] In the above embodiment, the sealing portion of the package is formed by a method of aligning the edge of the cover 2 with the edge of the opening of the casing 1 and co-rolling the inside of the casing. For a relatively large package, in order to maintain its strength, the wall of the casing 1 needs to be made thicker, which brings certain difficulties to the curling of the edge of the opening. Therefore, the casing 1 can take the structure of the double wall, and the edge of the casing 1 is attached to the edge of the cover 2, and then rolled into the casing 1 to form a sealing structure. For example, a package for packaging larger toys has a casing 1 diameter of up to 1000 m. The use of double-walled walls not only saves material, but also facilitates the use of the above-mentioned co-rolling process, and also ensures sealing to a certain extent.

[23] In other embodiments, it is not limited to the double-wall and the single-layer cover co-rolling, or the multi-layer wall and the single-layer or multi-layer cover may be co-rolled, as long as the strength and sealing of the package are ensured. Sexual requirements can be.

[24] Because the edge of the opening of the box is combined with the edge of the lid to form a roll, it is a purely mechanical combination, no glue is needed, so it is environmentally friendly and will not be lost due to deterioration of the glue after long day. The viscosity is not sealed; no hot pressing process is required, so the appearance is beautiful. After the crimping, a ring-shaped base in which the multi-layered material is closely adhered is formed, so that the strength is high and the sealing property is good.

The above-described embodiments are merely illustrative of several embodiments of the present invention, and the description thereof is not to be construed as limiting the scope of the invention. It should be noted that various modifications and improvements can be made by those skilled in the art without departing from the spirit and scope of the invention. Therefore, the scope of protection of the invention should be subject to the appended claims.
