Description

  The present invention relates to a packaging box that can be packaged while protecting a cap portion of a straight tube lamp.

  In general, a rectangular tube-shaped packaging material obtained by bending corrugated cardboard is used for packaging a fluorescent lamp that is a straight tube lamp. Moreover, the thing as described in the following patent document 1 is known as a packaging box of a compact type fluorescent lamp.

  In this packaging box, as shown in FIG. 11, a rectangular tube-like peripheral wall 51 into which a compact fluorescent lamp 61 is inserted is formed by connecting side plates 52 as respective surfaces thereof, and two opposing side plates are provided. An isosceles triangular inner end plate 53 is extended with the upper end side of 52 as one equilateral side, a holding piece 54 is provided continuously on one side of the inner end plate 53 inclined with respect to the equilateral side, and the upper end of the other side plate 52 is The outer end plate 55 and the insertion piece 56 are sequentially connected to the side.

  When packaging the fluorescent lamp 61 in the packaging box, the fluorescent lamp 61 is inserted into the peripheral wall 51, the pair of inner end plates 53 are bent in the direction of the opposing side plates 52, and the holding piece 54 is moved downward. Folding is performed, the protruding portion of the base 62 is sandwiched between the pair of holding pieces 54, the outer end plate 55 is closed, and the insertion piece 56 is inserted into the box and sealed.

  In recent years, as a lighting lamp for commercial buildings, public facilities, etc., instead of fluorescent lamps, power-saving and long-life straight tube LED lamps have begun to spread.

  Since such straight tube LED lamps are long and heavy, and the price is quite expensive, the cap is attached with a resin cap, and then inserted into a rectangular tubular cardboard packaging material in a lying state. Protects against load and impact of

Japanese Utility Model Publication No. 63-154425

  By the way, when packaging straight tube LED lamps, using not only corrugated packaging materials but also resin caps, packaging costs are high, so a packaging box with an end structure as described in Patent Document 1 is used. It is conceivable to use and protect the base.

  However, in this packaging box, when stacked in a lying state, the holding piece 54 does not function as a support column, so that the end of the peripheral wall 51 is deformed, a large load acts on the base, and the base may be damaged.

  In addition, the straight tube LED lamp corresponding to the 110W type fluorescent lamp has a length of about 2500 mm, and if it is to be inserted from the end face of the peripheral wall, a work space of 5 m or more is required, so that a work place can be secured. There is also a problem that it is difficult and requires careful work.

  Therefore, the present invention is intended to provide a packaging box that can protect a base such as a straight tube LED lamp from a large load without using a resin cap, and can easily carry out packaging work.

  In order to solve the above-described problems, the present invention provides a rectangular box-shaped peripheral wall into which a straight tube lamp is inserted, in a packaging box formed by continuously connecting side plates serving as respective surfaces thereof, at the end portion of the peripheral wall. From a triangular inner end plate extending with the end of the side plate as the base, a diagonal support plate and a restraining piece extending sequentially from two sides inclined with respect to the bottom of the inner end plate, and from the end of the side plate on the other side It has an extended outer end plate, and the oblique support plate and the restraining piece are sequentially folded into a mountain and a valley, and the inner end plate is bent in the direction of the opposing side plate, and repulsion is suppressed by the inner surface of the peripheral wall and the restraining piece. The slanted support plates are placed between the opposing side plates in a palm-mounted state, and the protruding portion of the base of the straight tube lamp is accommodated inside the space formed by the inner end plate and the slanted support plates. The outer end plate was closed.

  Further, the packaging box is divided into two in the length direction of the straight tube lamp, and the two half boxes are connected to each other, and one half box serves as a connecting portion with the other half box. A slit was made from the edge to the edge of the peripheral wall, and when connecting both half-boxes, the side plate forming the peripheral wall of one half-box was bent inward and inserted into the peripheral wall of the other half-box It is.

  In the straight tube lamp packaging box according to the present invention, both the oblique support plates extending from the triangular inner end plate are suppressed without spreading by the inner surface of the peripheral wall and the restraining piece, and the strut has a truss-like structure in the end portion of the peripheral wall. Since the pressure resistance strength from the outer peripheral direction of the end portion of the peripheral wall is strengthened, the protruding portion of the base accommodated in the space formed by the inner end plate and the both diagonal support plates is the product in the sideways state. Reliable protection from overload and impact.

  In addition, if a slit is made in the peripheral wall ridge part of one half box divided into two in the length direction of the straight tube lamp, it is smoothly inserted into the peripheral wall of the other half box while the side plate of that part is bent inward. Thus, the half-box bodies can be connected to each other, and even if the straight tube lamp is very long, the packaging operation can be easily performed without requiring a large work space.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  As shown in FIG. 1, this packaging box is a cardboard box for packaging a straight tube LED lamp 31 corresponding to a 110 W type fluorescent lamp. As shown in FIG. It is set as the structure which divides | segments and connects the two half box bodies 21 and 22 with the same outer periphery dimension.

  The straight tube LED lamp 31 conforms to the JEL801 standard, has a base 32 at both ends, one ground pin protrudes from the base 32 on one end side, and from the base 32 on the other end side, Two power supply pins protrude.

  The said half box bodies 21 and 22 are formed from a blank as shown in FIG.3 and FIG.4. In the blanks of the half-boxes 21 and 22, the side plates 2 which are the respective surfaces of the rectangular cylindrical peripheral wall 1 are continuously provided in five rows through long side crease lines. The reason why each blank has five rows of side plates 2 is to overlap the side plates 2 in the end rows on one surface of the peripheral wall 1 during assembly.

  Of the side plates 2 that overlap when the blanks are assembled, one side plate 2 is shorter than the other side plate 2, and one end thereof is a stopper edge 2 a when the half-box bodies 21 and 22 are connected.

  Among the side plates 2 that overlap at the time of assembly at the end portions of the blanks that are both ends of the packaging box, the inner side plates 3 that are isosceles triangles with the end sides as the base sides are formed on the end sides of the side plate 2 that is the inner side. The oblique support plate 4 and the restraining piece 5 are sequentially provided on two sides that are provided continuously and are inclined with respect to the bottom side of the inner end plate 3. The ruled lines at the boundary between the inner end plate 3 and the oblique support plate 4 and the boundary between the oblique support plate 4 and the restraining piece 5 are lead rules with intermittent cuts in order to reduce bending resistance.

  Further, among the side plates 2 that overlap when assembled, an end plate of the side plate 2 that is the outer side is connected to an intermediate end plate 6 that is obliquely cut at one side of the base, and an end side of the side plate 2 that is adjacent to the end plate. A trapezoidal middle end plate 7 is continuously provided.

  Furthermore, a square outer end plate 8 is connected to the side of the side plate 2 facing the side plate 2 to which the inner end plate 3 is connected at the time of assembly, and a sealing piece 9 is provided on one side of the outer end plate 8. It is connected continuously.

  An insertion piece 10 projects from the side plate 2 of one end row of each blank, and the U-shaped side plate 2 of the other end row has a U-shape along a ridge with the side plate 2 adjacent thereto. An insertion hole 11 is formed by cutting. Arc-shaped cuts 12 are formed at the ridges between the side plates 2 of each blank in order to reduce bending resistance.

  In the blank of the half box body 21, a notch to be a slit 23 is formed in the ridge portion of the peripheral wall 1 connected to the half box body 22, and a U-shaped cut is formed in the same ridge portion as the insertion hole 11. The insertion hole 24 is provided. And the corner | angular part of the side plate 2 of this edge part side is cut | disconnected diagonally. Further, the blank of the half box body 22 is provided with a connection lock piece 25 at an end on the connection side.

  In order to assemble the blank as described above into the shape shown in FIG. 1 and wrap the straight LED lamp 31, as shown in FIG. 2, the side plates 2 of the half-box bodies 21 and 22 are folded so as to be wound, The side plates 2 are overlapped to form a square cylindrical peripheral wall 1, and the insertion piece 10 is inserted into the insertion hole 11 to retain the shape of the peripheral wall 1.

  Next, the end of the half box body 21 which is one end of the packaging box is closed, and the straight tube LED lamp 31 is inserted into the peripheral wall 1 from the base 32 on the ground side, and then the straight tube LED lamp 31 is connected to the power supply side. Is inserted into the peripheral wall 1 of the half-box body 22, the half-box bodies 21 and 22 are connected, and the end of the half-box body 22 that is the other end of the packaging box is closed.

  At this time, in order to close the ends of the half-boxes 21 and 22 which are both ends of the packaging box, first, as shown in FIG. 5, the oblique support plate 4 is projected from the inner end plate 3 and the surface side of the cardboard is convex. Then, the restraining piece 5 is folded from the oblique support plate 4 so that the surface side of the cardboard is concave.

  Next, as shown in FIG. 6, when the inner end plate 3 is bent in the direction of the opposing side plate 2, the restraining piece 5 comes into contact with the end surface of the base 32, and the inner surface of the peripheral wall 1 and the restraining piece 5 are obliquely supported. The repulsion of the plate 4 is suppressed, and both the oblique support plates 4 are in a state where they are present between the side plates 2 facing each other in the palmed state.

  As a result, the protruding portion of the base 32 of the straight tube LED lamp 31 is accommodated inside the space formed by the inner end plate 3 and the both diagonal support plates 4, and in that state, as shown in FIGS. 7 and 8. As shown, the middle end plates 6 and 7 are bent, the outer end plate 8 is closed, and the sealing piece 9 is inserted into the box and sealed. 5 to 8 illustrate the end portion of the half box 22.

  And if both ends of a packaging box are closed in this way, the both diagonal support plates 4 function as struts that form a truss-like structure within the end of the peripheral wall 1, and the pressure resistance strength from the outer peripheral direction of the end of the peripheral wall 1 Therefore, the projecting portion of the base 32 accommodated in the space formed by the inner end plate 3 and the both diagonal support plates 4 is reliably protected from a load and an impact in a sideways state.

  Moreover, since the deformation | transformation in which the surrounding wall 1 becomes parallelogram shape is also prevented, the slip-out of the sealing piece 9 is prevented and sealing by tape sticking becomes unnecessary.

  On the other hand, in order to connect the half-boxes 21 and 22, as shown in FIGS. 9 and 10, the end side plate 2 having the slit 23 and the insertion hole 24 of the half-box 21 is connected to the half-box 22. It inserts in the inside of the peripheral wall 1 of the edge part which has the connection lock piece 25. FIG.

  At this time, since the corners of the side plate 2 of the half box body 21 are cut obliquely, the side plates 2 are guided to the inside of the peripheral wall 1 of the half box body 22, and slits 23 are inserted in the ridges of the peripheral wall 1. Therefore, the side plate 2 can be bent inward so that the outer peripheral diameter of the peripheral wall 1 becomes small, and can be smoothly inserted into the peripheral wall 1 of the half box 22.

  And when the stopper edges 2a of the half-box bodies 21 and 22 abut, the insertion of the half-box body 21 into the half-box body 22 is restricted, and the packaging box corresponds to the length of the straight tube LED lamp 31. The half-boxes 21 and 22 are fixed in a connected state by inserting the connection lock piece 25 into the insertion hole 24 with a predetermined dimension.

  With such a connection structure, the bending rigidity of the packaging box is secured by the insertion portion of the half box body 21 into the half box body 22, and the side plate 2 is doubled only on one surface having the stopper edge 2a. Since the side plate 2 is single on the other surface, the feeling of stiffness of the cardboard is suppressed.

  In addition, since the packaging box is divided into two in the length direction of the straight tube LED lamp 31, even if the straight tube LED lamp 31 is very long, it can be easily packaged without requiring a large work space. Can do.

  In addition, since the cardboard die can be made compact, the manufacturing cost of the packaging box can be suppressed, and the transportation cost to the manufacturer that manufactures the straight tube LED lamp can also be suppressed.

  In addition, in the said embodiment, since it illustrated about what wraps the long straight tube | pipe LED lamp 31 equivalent to a 110W type | mold fluorescent lamp, it is set as the structure divided into 2 in the length direction of the straight tube | pipe LED lamp 31, However, 20W type | mold When a short straight tube LED lamp corresponding to a 40 W fluorescent lamp is packaged, it is not necessary to have a two-divided configuration.

  Moreover, although illustrated about the case where a straight tube | pipe LED lamp is packaged, the above packaging boxes can be used also for the packaging of the conventional straight tube | pipe type fluorescent lamp.

  In addition, although the example having a buffer fixing structure for protecting the base at both ends of the packaging box is illustrated, when used for packaging such as a compact fluorescent lamp having a base at only one end, It is good also as what has a buffer fixation structure only in one edge part.
