DETAILED DESCRIPTION

[0032] In the following, the present disclosure is further explained in detail combining with the accompanying drawings and specific embodiments.

[0033] FIGS. 1 to 6 and FIGS. 10 to 11 shows a packaging box for an illumination source, the illumination source may be bulb lamp, corn lamp, halogen lamp, incandescent lamp, and the like, in the following, the technical scheme of the present disclosure is described mainly by taking the bulb lamp as an example:

[0034] A packaging box of the present disclosure comprises an enclosure body 100 having a cavity formed inside, the outer side wall of the enclosure body 100 forms the outer side wall of the packaging box (the packaging box is only composed of the enclosure body 100), the enclosure body 100 can enclose a bulb lamp 200 in the cavity along the circumferential direction thereof, the inner circumferential surface of the enclosure body 100 has at least one press-contact portion capable of abutting against the bulb lamp 200, the press-contact portion can press against and tightly hold the outer periphery of the bulb housing, so that the bulb lamp 200 can be stabilized in the cavity.

[0035] Specifically, the packaging box is composed only of the enclosure body 100, and no other structural parts, and the enclosure body 100 is composed only of one single cardboard (the cardboard material may be 300 grams of ivory board, 350 grams of ivory board, 350 grams of grey manila board, etc.) that bent into shape, or the enclosure body 100 may be composed of one single plastic sheet that bent into shape, however, when compared with the cardboard, the cost of using plastic sheet as the material of the enclosure body will be slightly increased. But when compared with the conventional art, the use of cardboard or plastic sheet greatly reduces the use of raw materials and greatly simplifies the production process.

[0036] In this embodiment, the enclosure body 100 is composed of one single cardboard or plastic sheet that bent to form a polygonal shape (using regular polygon, which makes it easier to package the illumination sources and easier to arrange and place the packaging boxes in the subsequent box packaging operation), that is, for the formed enclosure body 100, its inner circumferential surface extends along a straight line in the height direction of the cavity, and two end portions of the cavity are open, when compared with the existing packaging box, the opening of both ends saves the use of the cover material, and eliminates the manual work and process of folding the upper and lower covers compared with the conventional art, further reducing the production cost.

[0037] For the bulb lamp 200 with a bulb housing of a maximum outer diameter of 60 mm, it is most appropriate to bend the cardboard or plastic sheet into a regular hexagon shape (see FIG. 3), of course, regular quadrilateral shape (see FIG. 1), regular pentagon shape (see FIG. 2), regular heptagon shape (see FIG. 4), regular octagon shape (see FIG. 5) and so on can also be considered, and compared with the regular quadrilateral packaging design, in the case of equal inscribed circle diameter, the regular hexagonal packaging design has an enclosure body 100 with shorter perimeter, that is, the material is used less, and in the regular octagonal packaging design, in the case of equal inscribed circle diameter, although the regular octagonal packaging design has an enclosure body 100 with shorter perimeter, and the material is also used less, its single side width is narrow, which cannot meet the needs of LOGO printing on one side, therefore, after many verification considerations, a regular hexagonal shape is most appropriate for the bulb lamp 200 with a bulb housing of a maximum outer diameter of 60 mm.

[0038] In this embodiment, after the enclosure body 100 using cardboard as the material is bent to a regular polygonal shape, the inscribed circle diameter of its inner circumferential surface is smaller than the maximum outer diameter of the bulb housing of the bulb lamp 200, so that the enclosure body 100 can tightly hold the bulb housing of the bulb lamp 200 after the bulb lamp 200 is placed, and for the enclosure body 100 using cardboard as the material, it must be bent into a polygonal shape to effectively hold the bulb lamp 200, the inscribed circle diameter of the polygonal enclosure body 100 is less than the maximum outer diameter of the bulb housing, and when placing the bulb lamp 200 into the cavity, the periphery of the polygonal enclosure body 100 can be expanded outward, and if the enclosure body 100 is provided in cylindrical shape, the periphery of the enclosure body 100 cannot be expanded outward (or there is a very slight expansion, depending on the type of cardboard used), so the enclosure body 100 must be bent into a polygonal shape; specifically, for the case where the maximum outer diameter of the bulb housing of the bulb lamp 200 to be packaged is 60 mm, and the enclosure body 100 uses cardboard as the material, the inscribed circle diameter of the inner circumferential surface of the enclosure body 100 should be 57 mm, that is, the difference value between the inscribed circle diameter of the inner circumferential surface of the enclosure body 100 and the maximum outer diameter of the bulb housing is 3 mm, and the tightness of the difference of 3 mm is the most appropriate.

[0039] Of course, if the material of the enclosure body 100 is plastic sheet, according to the specific plastic material, the toughness and plasticity of the enclosure body 100 will be different, therefore, after the enclosure body 100 using plastic sheet as the material is bent into a polygon, the difference between the inscribed circle diameter of its inner circumferential surface and the maximum outer diameter of the bulb housing of the bulb lamp 200 may be selected according to the specific plastic material, which will not be repeated here. In addition, if the material of the enclosure body 100 employs plastic sheet, the enclosure body 100 can also be curled into a cylindrical shape besides being bent to a polygon, because the plastic material has better deformability than the cardboard, the inner diameter of the cylindrical enclosure body 100 can be slightly smaller than the maximum outer diameter of the bubble housing, and if the enclosure body 100 of the cardboard material is provided to be circular, the bulb lamp 200 cannot be held tightly when the inner diameter is too large, and the bulb lamp 200 cannot be placed in the cavity when the inner diameter is too small due to that the cardboard has no good deformability.

[0040] Further, the height of the cavity inside the enclosure body is at least greater than or equal to the length of one bulb lamp 200, or the height of the cavity may be greater than or equal to the length of two bulb lamps 200, or the height of the cavity may be greater than or equal to the length of three bulb lamps 200.

[0041] When the height of the cavity is greater than or equal to the length of one bulb lamp 200, the inner cavity of the enclosure body 100 can only accommodate one bulb lamp 200 (as shown in FIG. 10);

[0042] When the height of the cavity is greater than or equal to the length of two bulb lamps 200, the inner cavity of the enclosure body 100 can accommodate two bulb lamps 200 in the length direction, the inner circumferential surface of the enclosure body 100 has two press-contact portions capable of respectively abutting against the bulb housings of the two bulb lamps 200, that is, the bulb lamps 200 are packaged in the form of two-pack (as shown in FIG. 11);

[0043] When the height of the cavity is greater than or equal to the length of three bulb lamps 200, the inner cavity of the enclosure body 100 can accommodate three bulb lamps 200 in the length direction, the inner circumferential surface of the enclosure body 100 has three press-contact portions capable of respectively abutting against the bulb housings of the three bulb lamps 200, that is, the bulb lamps 200 are packaged in the form of three-pack.

[0044] Further, no matter the enclosure body 100 is composed of cardboard or plastic sheet, it is necessary to form a bonding portion 101 on one side of the enclosure body 100, the bonding portion 101 may connect and fix the two sides of the enclosure body 100 after the bending of the enclosure body 100, the difference is that when the enclosure body 100 is composed of cardboard, the bonding portion 101 may be fixedly connected with the other side of the enclosure body 100 by glue, and when the enclosure body 100 is composed of plastic sheet, the bonding portion 101 may be fixedly connected with the other side of the enclosure body 100 by high-temperature hot melting.

[0045] In addition, after packaging the bulb lamp 200 with the packaging box of the present disclosure, batches of packaging boxes may be placed in a larger packaging case 300 for arrangement and placement, the respective packaging boxes can be close to each other, with no space waste (as shown in FIG. 7), the batches of packaging boxes may be placed in a single layer (as shown in FIG. 8), may also be placed in two layers, but with the need of arranging a partition plate 301 between the two layers to separate them (as shown in FIG. 9), or may be placed in more than two layers.

[0046] In summary, the packaging box for an illumination source of the present disclosure is composed of one cardboard or one plastic sheet that bent into shape, which is simpler in manufacture and greatly reduces the use of raw materials compared with the conventional art; in addition, the packaging box stabilizes the illumination source in the cavity by the holding force of the enclosure body to the illumination source, which can meet International Standard ISO 2248-1985 (product drop test), and avoid the use of a package with inner liner to clamp product, which simplifies the production process and further reduces the use of raw materials, greatly reducing the production costs; due to the open design of the two end portions of the packaging box, the material consumption of the internal cavity caused by arranging the upper and lower covers is reduced, and cancel of the upper and lower covers greatly facilitates the operation of placing and picking the illumination source.

[0047] Although the present invention has been disclosed in the form of embodiments and variations thereon, it will be understood that numerous additional modifications and variations could be made thereto without departing from the scope of the invention.

[0048] For the sake of clarity, it is to be understood that the use of ‘a’ or ‘an’ throughout this application does not exclude a plurality, and ‘comprising’ does not exclude other steps or elements.
