BACKGROUND OF THE INVENTION
The present invention relates to specification switching member which is inserted vertically in a cardboard box that is formed by at least one of the inner and outer flaps and top and bottom surfaces a rectangular shape.
[0002]
[Prior art]
The prior art will be described by taking the most common cardboard box (referred to as A-1 type case) classified as “0201 type” of JISZ1507 as an example.
[0003]
The cardboard box, as shown in FIGS. 8 to 1 0, and both side lengths surface 1,1, cylindrical body A by the both side width surface 2,2 is formed, provided on both upper and lower sides of the main body A The pair of inner flaps 3 and 3 and outer flaps 4 and 4 are folded inward and outward to form an upper surface and a bottom surface.
[0004]
Here, the length dimension f1 (shown in FIG. 8 ) of the inner flaps 3 and 3 is such that the tips of the inner flaps 3 and 3 are separated from each other in the folded state, and the width dimension f2 of the outer flaps 4 and 4 is in the folded state. The size is set so that the tips of each other touch each other.
[0005]
In this corrugated cardboard box, the contents are stored separately orderly the contents to prevent or each other collide or scattered clutter inside and reinforced against compressive load W in the vertical direction indicated by the arrow in FIG. 1 0 A partition plate may be provided for the purpose.
[0006]
In the figure, a case where a pair of U-shaped partition plates 5 and 5 in which blade pieces 7 and 7 are integrally provided on both sides of the main portion 6 is used is illustrated.
[0007]
The partition plates 5 and 5 have the main portions 6 and 6 in contact with each other back to back and cross the lengths 1 and 1 of the box body A, and the side wing pieces 2 and 2 have lengths on both sides. It is inserted vertically into the box body A in contact with the inside of the surfaces 1 and 1.
[0008]
Conventionally, the upper and lower end surfaces of the partition plates 5 and 5 are flush with each other (the height dimension is uniform throughout). The body A is divided into left and right by the partition plates 5 and 5, and the inner and outer flaps are separated. 3 and 4 are supported in a folded state, and the entire box is reinforced particularly with respect to the compressive load W in the vertical direction.
[0009]
[Problems to be solved by the invention]
However, the conventional partition plate 5 has the following drawbacks.
[0010]
As shown in FIG. 1 0, between a state of closing the inner and outer flaps 3 and 4, but the inner flap 3 is supported in contact with the wing piece portions 7, and the inner flap 3 and the outer flap 4 Since a step a occurs in the gap, a gap corresponding to the step a is formed between the outer flap 4 and the partition plates 5 and 5, and the outer flaps 4 and 4 are not supported by the partition plates 5 and 5 until the gap is filled. Become.
[0011]
Therefore, up to the compression amount of the gap, the reinforcing function of the partition plates 5 and 5 hardly works, and the compression load W must be supported only by the box. The purpose of the period was not fully met. For this reason, the amount of compressive deformation of the box is increased, and the contents may be damaged.
[0012]
The present invention eliminates the clearance between the outer flap and the partition plate to fill the level difference between the inner and outer flaps, to support the compressive load applied to the outer flap from the first specification carton can be enhanced compressive strength A cutting member is provided.
[0013]
[Means for Solving the Problems]
This onset Ming, both side lengths surface, both side width surface comprises a top surface and a bottom surface, at least one of said top and bottom, vertically cardboard inner box formed by a pair of inner flaps and outer flaps folded in and out The partition member to be inserted has the following configuration.
[0014]
(A) It consists of a pair of partition plates.
[0015]
(B) The both partition plates are formed by extending a pair of wing pieces at right angles on both sides of the main portion that crosses between the length surfaces on both sides of the cardboard box.
[0016]
(C) The H-shaped assembly in which the both side blade pieces extend in the same direction, and the pair of partition plates are back-to-back with the main parts back to back, with a half-cut line connected by only one side liner of the cardboard. It is configured to be assembled and deployed in a state and a flat-plate-like deployed state.
[0017]
(D) An outer flap supporting portion for supporting the outer flap is a region straddling the main portion of the both partition plates and a base side portion of the both-side blade pieces continuous to the main portion, and the other region is the inner flap. To be the inner flap support part that supports
[0018]
(E) Both end portions in the height direction of the outer flap support portion protrude outwardly from the inner flap support portion to form a convex portion, and this convex portion fills the step between the inner and outer flaps and fills the outer flap. that it is configured to contact the.
[0019]
According to the above configuration, in a state of inserting the specification switching member in the box, eliminating the clearance between the outer flap and the partition member to fill the level difference between the inner and outer flap by the convex portion, the first from the partition member (protrusion) Since the outer flap can be supported by this, the reinforcing effect against the original compressive load of the partition member can be enhanced and the compressive strength of the entire box can be improved .
[0020]
In this case, making the integral of two partition plates from one cardboard, for installation into the box in one piece (partition member), it is possible to improve the assembling workability of the box. In addition, since production errors and installation errors of both partition plates are unlikely to occur, the compressive load support action by both partition plates is evenly performed, and the effect of improving the compressive strength becomes higher.
[0021]
DETAILED DESCRIPTION OF THE INVENTION
The embodiments of the present invention will be described by FIGS. 1-7.
[0022]
In the following embodiments, the “0201 type” cardboard box (A-1 type case) of JISZ1507 is taken as an example in accordance with the description of the prior art. Also omitted, in the following embodiments, since configuration cardboard box itself is the same as the conventional, the same parts as the parts shown in FIGS. 8 to 1 0 are denoted by the same reference numerals, and the duplicated description.
[0023]
The implementation partition according to the member B is Ru is constructed by integrating the partition plates 11, 11 of a pair of U-shaped.
[0024]
Both partition plates 11 and 11, like the partition plate 5 and 5 shown in FIGS. 8 and 9, each formed Tsubasahen portions 13 on both sides of the main portion 12 is extended in the same direction in the U-shape As shown in FIGS. 1 to 3, the main parts 12 and 12 are in contact with each other and cross between the lengths 1 and 1 on both sides of the box body A, and the side blade parts 13 and 13 are It is inserted vertically into the box body A in an H-shaped state in contact with the inside of the length surfaces 1 and 1 on both sides.
[0025]
The partition member B (both partition plates 11 and 11) is manufactured by cutting a rectangular cardboard as shown in FIGS. 4 to 6, and the main parts 12 and 12 are only one side liner of the cardboard. Assemble and unfold into the H-shaped assembled state in which the main parts 12 and 12 are back to back as shown in FIGS. 1 to 3 and the flattened expanded state shown in FIG. It is configured freely.
[0026]
The partition plates 11, 11 have outer flap support in which the regions straddling the main portion 12 and the base side portions of the side blade piece portions 13, 13 continuous to the main portion 12 support the outer flaps 4, 4. A portion S1 (see FIG. 4) and the end side regions of the remaining side blade pieces 13 and 13 form an inner flap support portion S2 that supports the inner flaps 3 and 3.
[0027]
Here, both end portions in the height direction of the outer flap support portion S1 protrude outward from the inner flap support portion S2 by the thickness of the outer flap 4 (corrugated cardboard as a material for the box) to form a convex portion 14. As shown in FIG. 7, the projecting portion 14 fills the step a between the inner and outer flaps 3 and 4 and contacts the outer flap 4 with the partition member B inserted into the box.
[0028]
Therefore, by using this partition member B, the outer flap 4 can be supported by the convex portion 14 from the beginning (before the compression load W acts) as shown in FIG. The box can be prevented from being deformed by the gap, and the compressive strength of the entire box can be increased.
[0029]
Table 1 shows the result of the packing compressive strength test conducted by the inventor in order to confirm the reinforcing effect of the partition member B.
[0030]
Test, using a conventional pair of partition plates 5 and 5 shown in FIGS. 8 to 1 0, the partition member B according to the implementation embodiments, both of the same material, the material of the cardboard box is applied partition member B A box having a lower strength than a box in which a conventional product is used was used.
[0031]
[Table 1]

[0032]
As is clear from the above table, the packing compressive strength could be greatly increased even if the material of the cardboard box was lowered. For this reason, the amount of compression of a box can be made small and the contents can be protected reliably.
[0033]
In addition, since the pair of partition plates 11 and 11 are integrated and installed in the box as an integrated object, the assembling workability of the box can be improved, and manufacturing errors and installation errors of the partition plates 11 and 11 occur. Since it is difficult, the support function of the compressive load by the partition plates 11 and 11 is evenly performed, and the effect of improving the compressive strength becomes higher .
[0034]
In time and, in the above embodiment has illustrated cardboard box both upper and lower surfaces are formed by inner and outer flaps ( "0201 form" of JIS Z1507) as the application target, the present invention is at least one of the top and bottom surfaces The present invention can be widely applied to cardboard boxes formed by inner and outer flaps similar to the above embodiment.
[0035]
