The specific implementation mode is as follows:
the present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1, the packaging container is formed by two-part engagement of a first sheet 100 and a second sheet 200. Wherein the EPE material is used for both the first sheet 100 and the second sheet.
As shown in fig. 1 and 2, the first sheet 100 includes three portions, namely, a first side 101 for forming the container, and a second side 102 and a third side 103 connected to the first side, the three portions are integrated into a rectangular sheet before being folded, a first folding groove 104 is formed at the connection portion of the second side 102 and the first side 103 to the first side 101, and the first sheet 100 is folded along the first folding groove 104 to form a u shape. The width and depth of the first folding groove 104 may be selected according to the thickness of the product. An engaging groove 105 for engaging with the second sheet 200 is formed in the edge surface of the first sheet 100.
As shown in fig. 1 and 3, the second sheet 200 also includes three portions, namely, a fourth side 201 for forming the container, and a fifth side 202 and a sixth side 203 connected to the fourth side 201, and similarly, the three portions are also integrated, and before folding, the sheet is a rectangular sheet, and a second folding groove 204 is formed at the connection position of the fifth side 202, the sixth side 203 and the fourth side 201, and the u shape is also formed after the second sheet is folded along the second folding groove 204. The width and depth of the second folding groove 204 is the same as the width and depth of the first folding groove 104 of the first sheet 100. An engaging projection 205 is formed at an edge end of the second sheet for engaging with the first sheet 100.
The first folding groove 104 and the engaging groove 105 of the first sheet 100 and the second folding groove 204 and the engaging projection 205 of the second sheet 200 are formed by embossing. The bottom of the molded fold channel 104, 204 may protrude toward the outer surface of the sheet to facilitate side folding. The folding grooves 104 and 204 are inverted splayed, wherein a convex strip can be molded on one side of the inverted splayed, a groove can be molded on the other side, and when two adjacent side surfaces are folded to be in a vertical state, the convex strip on one side of the folding groove is clamped into the groove on the other side, so that the sealing effect between the two side surfaces is improved.
The engaging protrusion 205 may be formed in a drop-like structure as shown in fig. 3, a lance-like structure, a substantially dovetail-like structure, or other structures that facilitate processing and facilitate engagement, and the engaging groove 105 may be formed to match the shape of the engaging protrusion 205.
In order to achieve better sealing, a plurality of small grooves may be provided on the engaging protrusion 205, a plurality of small ribs are correspondingly provided in the engaging groove 105, and the small ribs and the small grooves form a tight fit. The number of the small convex ribs and the small grooves is preferably four. To the setting of little protruding muscle in the block groove 105, wherein two little protruding muscle settings are in the position that is close to the recess opening, two liang of oppositions, and two other little protruding muscle are relative salient along the direction that is roughly parallel to the sheet surface, and two other little protruding muscle symmetries set up the position that is close to the recess bottom. The small groove on the engaging protrusion 205 is disposed corresponding to the small rib in the engaging groove 105.
How the two sheets are combined into a packaging container is described below in connection with fig. 1.
Firstly, the second side 102 and the third side 103 of the first sheet 100 are turned upwards along the first folding groove 104 to form a u shape as shown in fig. 1, similarly, the fifth side 202 and the sixth side 203 of the second sheet 200 are turned upwards along the second folding groove 204 to form a u shape as shown in fig. 1, the engagement protrusion 205 on the folded u-shaped second sheet 200 is inserted into the engagement groove 105 of the folded u-shaped first sheet 100, during the engagement process, the small convex rib in the engagement groove 105 is engaged with the small groove on the engagement protrusion 205, and the tight fit formed between the engagement protrusion 205 and the engagement groove 105 enables the self-sealing of the packaging container formed by combining the first sheet 100 and the second sheet 200.
The above only describes a combination of the packaging container, for the purpose of convenient operation, any one of the surfaces can be selected as the bottom surface, or the sequence of the side surface folding is selected, and it is not necessary that both sheets are folded into u shape and then fastened, for example, the second side surface 102 of the first sheet 100 can be folded to be perpendicular to the first side surface 101, the second side surface 102 is used as the bottom surface, the first side surface 101 is used as the rear surface, the three surfaces of the second sheet 200 folded into u shape are fastened to the bottom surface and the rear surface to form the containing space, then the article is placed, and finally the third side surface 103 is fastened as the top surface.
For the articles with high sealing requirements, a layer of adhesive tape can be wound outside the articles or plastic package is carried out, and then further sealing can be formed.
A protective layer may be further added to the inside and/or outside of the first sheet 100 and the second sheet 200, and the protective layer may be bonded to the sheets by bonding, laminating, overlaying, or other suitable means, wherein the inner protective layer is made of a material having a hardness lower than that of the sheets and a certain softness, and the outer protective layer is made of a material having a hardness higher than that of the sheets, so as to enhance the strength of the container.
The above description is only a preferred embodiment of the present invention, and therefore should not be taken as limiting the scope of the utility model, which is defined by the appended claims and their equivalents and modifications within the scope of the description.
