As used in the description of the embodiments of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
Referring to fig. 1-5, the embodiment of the present invention provides a hot melt adhesive paper packaging box with firm bonding, and as can be seen from the figure, the hot melt adhesive paper packaging box with firm bonding comprises a box body 10, an upper glue plate 4, a bonding plate 6 and a rocking cover 5. The box body 10 comprises a front surface 1, a back surface 2 and two side surfaces 3.
The gluing plate 4, the bonding plate 6 and the rocking cover 5 are all arranged at the opening of the box body 10.
The bonding plate 6 is fastened with the rocking cover 5 through a buckle 7. The adhesive plate 6 and the rocking cover 5 are not easy to separate through the buckle 7, and the matching is firm.
The bonding plate 6 is provided with grains 8; the upper adhesive plate 4 is connected with the bonding plate 6 through hot melt adhesive; the hot melt glue penetrates into the texture 8. The permeability of the hot melt adhesive can be improved through the lines 8 at the bonding plate 6, so that the bonding strength is improved.
In some embodiments, such as this embodiment, the ridges 8 are serrated lines. The serrated knife line is formed by serrated knife machining.
Alternatively, in other embodiments, the texture 8 is a half-hole or a cut groove. The half-pressed hole is formed by processing through a half-pressing process. The cutting groove is formed by a cutting process.
In the utility model, the space between the lines 8 is related to the size of the bonding plate 6 and the distance between the gluing points, if the space between the lines 8 is too small, the production cutting is too close, and the paper box is easy to be damaged; if the spacing distance between the lines 8 is too large, the hot melt adhesive is not easy to permeate.
Therefore, the spacing d between the ridges 8 satisfies
Wherein, a is the length of the bonding plate 6, b is the width of the bonding plate 6, and c is the distance between the gluing points of the hot melt adhesive.
Further, the depth of the ridges 8 is related to the thickness of the adhesive sheet 6. In the utility model, the depth f of the lines 8 is more than or equal to 0.3e and less than or equal to 0.7 e; wherein e is the thickness of the adhesive sheet 6.
Further, the box body 10, the gluing plate 4, the bonding plate 6 and the rocking cover 5 are all made of cardboard.
Further, the outer surface of the paperboard is provided with a protective layer. The protective layer may be specifically a film coating layer or an oil coating layer.
Further, the material of the paperboard is one of white cardboard, grey cardboard, white bottom white cardboard and grey bottom white cardboard.
Further, the gram weight of the paperboard is 190g/m2～500g/m2And certain strength and certain toughness of the paperboard are ensured.
Furthermore, cutting lines are processed on the upper rubber plate 4, so that a user can conveniently open the hot melt adhesive paper packaging box which is firmly bonded.
Furthermore, the cutting lines enclose a prepressing shape, the length i of the prepressing shape is more than or equal to 0.2g and less than or equal to i and less than or equal to 0.6g, and the width j of the prepressing shape is more than or equal to 0.2h and less than or equal to j and less than or equal to 0.6 h; wherein g is the length of the upper glue plate 4 and h is the width of the upper glue plate 4.
Further, the cutting depth of the cutting line is the same as the thickness of the upper rubber plate 4. And the cutting line needs to be discontinuous to ensure that the cutting line cannot fall off under the condition of no action of external force.
Further, the hot melt adhesive is a rubber pressure-sensitive hot melt adhesive, the softening temperature of the hot melt adhesive is 90-92 ℃, the temperature-viscosity curve is shown in figure 5, and the main relationship is as follows: 180-3050-3150 cps, 170-3900-4000 cps, 160-5150-5250 cps and 150-7050-7150 cps. If the viscosity of the hot melt adhesive is too high, the fluidity of the hot melt adhesive is small, and the production is difficult, so that the preferable heating range of the hot melt adhesive is 165-190 ℃ in the actual production process.
It should be further noted that the outer surface of the paperboard is provided with a protective layer (a film coating layer or an oil coating layer), so that the bonding surfaces of the bonding plate 6 and the rocking cover 5 are provided with the protective layer, and if a conventional hot melt adhesive is used, the protective layer affects the performance of the hot melt adhesive, so that the bonding is not firm, and the glue is not adhered. Therefore, in the embodiment, for the adhesion of the packaging box with the protective layer on the adhesion surface, the rubber pressure-sensitive hot melt adhesive is specially selected, and the rubber pressure-sensitive hot melt adhesive has a temperature-viscosity curve as shown in fig. 5, and is matched with the texture and the buckle, so that the firm adhesion of the packaging box can be further ensured.
