Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a synthetic resin bottle box having a lattice-like bottom rib. This invention relates to a synthetic resin bottle box in which bottle boxes twice the size can be stably stacked.

(Prior Art) Generally, synthetic resin bottle boxes are used to store and transport bottles for beer, soft drinks, etc.
These bottle boxes generally have a lattice-like rib on the bottom, and a space inside to store the bottles in isolation.
20 by vertical and horizontal lattice-like partition walls installed between the side walls.
There are 30 compartments, and bottles are stored in these compartments. These bottles and boxes are stored and transported in a stacked state.

(Problem to be solved by the invention) However, when a large number of bottles are stored in one box like this, it is heavy and inconvenient to carry.

Therefore, in recent years, conventional bottle boxes have been made smaller by splitting and molding them into half the size, and bottle boxes with a structure that connects the two split-molded bottle boxes to each other during storage have been developed. is proposed.

FIG. 1 is a plan view showing a conventional bottle box.

A is an upper flange provided at the upper end of the four circumferential side walls. Inside, a compartment d for storing the bottle is formed by a lattice-shaped partition wall c, and a lattice-shaped bottom rib e forms the bottom part f. are doing. The bottom part f protrudes below the lower flange g at the lower end of the side wall, and when stacked, it fits into the upper opening of the lower bottle box to ensure stable stacking. In this example, a bottle box containing 20 bottles is shown, but in order to achieve miniaturization, the bottle box is divided in the longitudinal direction, for example, at a partition wall located at a position half the length l in the transverse direction. When the two bottle boxes are molded separately in this way, side walls are naturally formed in the divided portions as well. Even if you try to butt two bottle boxes that have been formed separately in this way and stack a conventional size bottle box that has not been split and formed on top of these bottles, the bottoms of the conventional bottle boxes will overlap the side walls where they are butted together. Since it is placed on the top edge and does not fit into the top opening, stable stacking is not possible.

This idea was made in view of the current situation, and its purpose was to transform the conventional bottle box into a two-dimensional design.
A synthetic resin bottle box that can be split and molded into 1/2 the size, and by butting two of these split molded bottle boxes together, can stably stack the conventional size bottle boxes before splitting. This is what we intend to provide.

(Means for solving the problem) In order to achieve the above purpose, this invention has the following configuration.

It consists of a bottom frame whose bottom part protrudes downward from a lower flange with four circumferences, and bottom ribs formed in a lattice shape inside the bottom frame, and a compartment for storing bottles is formed by a lattice-shaped partition wall inside the side wall. In a rectangular bottle box, convex portions and concave portions are formed alternately in a wavy shape on the upper surface of one long upper frame, the convex portions and concave portions are connected by an inclined surface, and further, the concave portions are made long in a plane. Formed on the extension line of the bottom rib and bottom frame perpendicular to the side wall,
When the depth of the recess from the upper surface of the adjacent short upper frame is y, and the height of the bottom protruding from the lower flange is z, y≧z.

(Function) Even if bottle boxes twice the size in plane are stacked on the upper tier with the long upper frame sides with the recessed portions butted against each other, the bottom rib and the bottom frame will fit into the recessed portions.

Therefore, the bottom of the upper bottle box is not placed on the upper frame of the lower bottle box.

Further, the sloped surface that connects the convex portion and the concave portion allows for smooth withdrawal without the bottom rib and bottom frame being caught when the upper bottle box is pulled out.

(Example) Hereinafter, this invention will be described in detail based on an illustrative example.

Figures 2 to 5 show bottle boxes that can be detachably connected.Bottle box H has four corner supports 1, 2, 3, and 4 connected below by long side walls 5, 6 and short side walls 7, 8. Furthermore, the upper end portions are attached to long upper frames 10, 11 and short upper frames 12, 1.
3, and the portion surrounded by the pillars, side walls, and upper frame is a window 14. Therefore, in this embodiment, the long upper frames 10, 11 and the short upper frames 12, 13
is used as a handle.

The bottom part 15 of the bottle box H consists of a bottom frame 18 and a bottom rib 9. The bottom ribs 9 are provided in a lattice pattern within the bottom frame 18. Inside the bottle box H, a compartment 17 is formed by a grid-like partition wall 16 to separate and store the bottles. Furthermore, a lower flange 19 is provided protruding from the outer surface of the lower end portion of the side walls 5 to 8.

Therefore, the bottom 15 protrudes below the lower flange 19, and when stacked, the lower flange 19 is placed on the upper frames 10 to 13, and the bottom 15
fits into the upper opening.

Next, the long upper frame 10 will be explained.

The upper surface of the long upper frame 10 is formed into a wave shape.
The corrugated convex portion 10a is slightly lower than the upper surface of the short upper frames 12, 13, and the corrugated concave portion 10b has the bottom rib 9 fitted onto an extension line of the bottom rib 9 which is orthogonal to the long side walls 5, 6 in a plane. It is formed to a size that Therefore, when bottle boxes of twice the size are stacked on top of each other, the bottom ribs of the bottle boxes of twice the size fit together. The convex portion 10a and the concave portion 10b form an inclined surface 10.
Continuous by c.

That is, the depth of the upper surface of the long upper frame 10, that is, the depth of the protrusion 10a from the upper surface of the short upper frames 12 and 13 is x, the depth of the recess 10b is y, and furthermore, When the height dimension of the protrusion of the bottom part 15 from the lower surface of the lower flange 19 provided is z, x<
z≧y, preferably x<(1/2 to 3/4)z. Further, it is desirable that the slope 10c has a slope as gentle as possible.

The upper surface of the long upper frame 10 is wave-shaped, and the protrusion 10a is formed lower than the upper surface of the short upper frames 12 and 13 to facilitate pulling out during loading and unloading, but the upper surface of the protrusion 10a is It may be on the same surface as the short upper frames 12 and 13, that is, x=0. Further, the convex portion 10a and the concave portion 10b may be curved surfaces.

With this structure, bottle boxes H with the same shape
When stacking so-called sticks, the bottom frame 18 is locked by the protrusion 10a, allowing safe stacking.

In addition, when two bottle boxes are connected with their long side walls 5 facing each other, and two bottle boxes of twice the size are stacked with the same lattice-like bottom ribs formed on the upper tier, the bottom of the upper tier The rib will fit into the recess 10b. Therefore, unlike in the past, the bottom of the upper bottle box is not placed on the upper frame of the connected lower bottle box H, but is completely fitted into the upper opening of the lower bottle box, reducing the risk of slipping. Can be safely stacked without any damage.

Furthermore, the convex portion 10a and the concave portion 10b of the long upper frame 10
are continuous by the slope 10c, so even when loading and unloading a bottle box twice the size, just by slightly lifting the bottom of the upper bottle box in front of it, it can be pulled out smoothly without getting caught. .

Next, another structure of this bottle box H will be explained.

The corners of pillars 2 and 3 are said to be rounded,
The corners of the pillars 1 and 4 are formed at approximately right angles.
The long side wall 5 side of the support 1 has a dimension l from the outer surface of the long side wall 5.
The outer surface is provided with hooks 31, 32, and 33 that are L-shaped in plan and protrude outward.

On the other hand, the support column 4 has a so-called double wall structure in which a triangular gap 36 is formed between the inner wall 34 and the outer wall 35, and the hooks 31, 32 are provided on the long side wall 5 side of the outer wall 35. and 33 are inserted into insertion holes 37, 38, and 39. Furthermore, a small hole 40 into which a positioning protrusion of a connecting member, which will be described later, fits is formed on the short side wall 8 side of the outer side 35 (see FIG. 5). The upper surface of the cavity 36 is closed, but the lower surface is open so that a connecting member can be inserted therein, and an insertion hole 42 into which the end of the handle can be inserted is formed in the upper part of the cavity 36 (Fig. 12). ~See Figure 14).

Next, the connecting member 50 inserted into the cavity 36 will be explained.

As shown in FIGS. 6 to 10, the structure of the connecting member 50 is that a recess 52 is formed by cutting the upper part of a slide plate 51, and an upper plate 5 facing upward is formed in this recess 52.
3, a rack-shaped tooth 54 is provided, and the rear end of the slide plate 51 is provided with a pawl 55, which is orthogonal to the axial direction.
56 and 57 are provided protrudingly.

Further, in detail, the rack-shaped tooth 54 is formed in the recess 5.
2, and is provided only on the upper part of the rack tooth 54.
A reinforcing plate 58 is integrally formed on one side. Rear plates 60, 61 are connected to the claws 55, 56, and horizontal reinforcing plates 62, 63 are provided above the rear plates 60, 61. The back plates 60 and 61 prevent rattling within the gap 36. Furthermore, a substantially triangular bottom plate 64 having substantially the same shape as the gap 36 of the support column 4 is integrally provided at the lower part of the pawl 57 . The bottom plate 64 prevents foreign matter from entering the cavity 36.

Hooks 31, 32, 33 are inserted into hook insertion holes 37,
38 and 39 respectively, and when the connecting member 50 inserted into the gap 36 is raised, the pawl 5
5, 56 and 57 are configured to engage with hooks 31, 32, 33. Therefore, hook 3
It is preferable that the inner surfaces of 1, 32, and 33 are sloped surfaces that gradually become thicker toward the bottom. In this way, when the inner surfaces of the pawls 55, 56, and 57 are formed into sloped surfaces, there is no looseness in the engagement state with the hook, and the connection can be made more securely.

Reference numeral 65 denotes a flexible piece for positioning the connecting member 50. The flexible piece 65 for positioning is separated on three sides by a notch 66, and has a protrusion 67 formed on the outer surface of its lower end. The projection 67 of the flexible positioning piece 65 is configured to be inserted into a small hole 40 formed in the outer wall 35 of the support column 4.

FIG. 11 shows a handle 70 rotatably supported on the outer surface of the upper frame of the bottle box H.

The tip of the handle 70 is rotatably supported by the upper frames 12 and 13, and is configured to fit into the outer surfaces of the upper frames 11, 12, and 13 when the handle 70 is laid down horizontally.

That is, the handle 70 is attached to the short upper frame 12 by inserting the pins 74 into the mounting holes 72 and 73 formed at the tip thereof.
and 13 so as to be rotatable. Therefore,
When the handle 70 is rotated and made horizontal, the upper frame 11,1
2 and 13 so that other bottle boxes can be stacked on top. One end of the handle 70 is inserted into the gap 36 of the support column 4 when rotated horizontally, and the end has the hook-shaped teeth 54 of the connecting member 50.
Pinion-shaped teeth 75 are provided which mesh with.

Next, the operation for connecting or separating the bottle boxes H according to the above configuration will be explained.

First, when connecting two bottle boxes H, use the handle 7
0 to rotate the grip portion 76 upward, thereby releasing the meshing state between the pinion-shaped teeth 75 at the end and the rack-shaped teeth 54 of the connecting member 50,
Point the pinion-shaped teeth downward. pinion tooth 75
When the connecting member 50 is rotated downward to push down the connecting member 50 and completely release the engaged state, the protrusion 66 of the positioning flexible piece 65 of the connecting member 50 that has been pushed down while pressing the inner surface of the external wall 35 is fitted into the small hole 40. By fitting the projection 66 into the small hole 40, the connecting member is held without inadvertently moving up and down.

When the protrusion 66 fits into the small hole 40, the connecting member 5
0 claws 55, 56 and 57 are all insertion holes 3
7, 38, and 39, the insertion holes 37, 38, and 39 are completely opened (see FIG. 12).

In this way, by rotating the handle 70, the connecting member 50 is pushed down and the insertion holes 37, 3 are pushed down.
After opening 8 and 39, the long side walls 5 are butted together and the hooks 31, 32 and 33 of the mating bottle box are inserted into the insertion holes 37, 38 and 39, respectively.
Next, when the handle 70 is rotated to raise its tip, the upper end of the pinion-shaped teeth 75 first comes into contact with the upper plate 53, and then engages with the rack-shaped teeth 54, and the handle 7
0 rotates, the connecting member 50 gradually rises, and the handle 70 becomes horizontal and the upper frame 11,1
2 and 13, the connecting member 50
is pulled up to the top.

When the connecting member 50 is pulled upward, the protrusion 67 of the flexible positioning piece 65 separates from the small hole 40 and rises while pressing the inner surface of the external wall 35.
The claws 55, 56 and 57 are inserted inside the hooks 31, 32 and 33, and the two bottle boxes H are completely connected (see FIGS. 13 and 14).

Next, to separate the two connected bottle boxes, as is clear from the above, rotate the handle 70,
When the meshing between the rack teeth 54 and the pinion teeth 75 is released, the connecting member 50 is pushed downward, and the pawls 55, 56 and 57 and the hooks 31, 32
and 33 are also released, and the insertion holes 37,
Since 38 and 39 are open, the two bottle boxes H can be separated by pulling out the claws 55, 56 and 57.

As in the above embodiment, the connecting member is raised and lowered by the rotation of the handle, and the hook is moved up and down by engaging the rack-shaped teeth formed on the connecting member and the pinion-shaped teeth formed at the tip of the handle. When the bottle box is connected by engaging the claws, the following effects can be obtained.

In other words, if the device is separated into two pieces when carried, it is lightweight and convenient, and can be carried in the hand.

By butting two bottles together and connecting them, they can be stacked stably and safely stored and transported.

Moreover, since a plurality of teeth mesh with the tip of the handle and the connecting member through the rack-shaped teeth and pinion-shaped teeth, the vertical stroke of the connecting member 50 can be increased, and the meshing is ensured. Furthermore, since it is only necessary to rotate the handle 70, the connection and separation operations are easy.

Figures 15 and 16 show other embodiments of this invention. In the above embodiment, the bottle boxes that can be connected have been described, but the bottle boxes Ha shown in this embodiment cannot be connected. This bottle box Ha has four corner supports 8
0 are connected by a long side wall 81 and an end side wall 82, and the upper part is connected by a short upper frame 79 and a long upper frame 83 having a U-shaped cross section.

Support column 80, side walls 81, 82 and upper frame 79, 83
The part surrounded by is a window 84, and the bottom frame 89
A bottom portion 85 is formed by the bottom rib 86 and the bottom rib 86 . The bottom frame 89 is similar to the upper frames 79 and 83 in a plane.
The support column 8 is positioned inside the inner surface of the support column 8.
0, connected from the lower ends of the side walls 81 and 82,
The bottom ribs 86 are provided in the bottom frame 89 in a grid pattern. Furthermore, inside the side wall, there is a grid-like partition wall 8.
A compartment 88 for storing bottles in isolation by 7.
is formed.

Furthermore, a lower flange 90 is provided protruding from the lower ends of the support column 80 and the side walls 81, 82. Therefore, the bottom part 85 protrudes below the lower flange 90, and when stacked, the lower flange 90 is placed on the upper frames 79, 83, and the bottom part 85 is fitted into the upper opening of the lower bottle box. Ru.

The upper surface of either one of the long upper frames 83 is formed into a wave shape consisting of a convex portion 91 and a concave portion 92. The upper surface of the convex portion 91 is lower than the upper surface of the short upper frame 79, and the recessed portion 92 is formed in a size such that the bottom rib fits on an extension line of the bottom rib perpendicular to the long side wall 81 in a plane. Therefore, when bottle boxes Hb of twice the size are stacked on top, the bottom rib 86a and bottom frame 89a of the top bottle box fit together. Further, the convex portion 91 and the concave portion 92 are continuous by an inclined surface 94.

That is, the recess 92 is located below the bottom rib 86a and bottom frame 89a of the upper bottle box, and the depth from the top surface of the short upper frame 79 to the top surface of the protrusion 91 is x,
The depth of the recess 92 is y, and the bottom 85
If the protruding height dimension from the lower flange 90 is z, then x<z≦y, preferably x<(1/2 to 3/
4) Let it be z.

Note that the upper surface of the convex portion 91 and the upper surface of the short upper frame 79 may be on the same plane. The convex portion 91 and the concave portion 92 are continuous by an inclined surface 94, and it is desirable that the inclined surface 94 has a slope as gentle as possible.
Further, the convex portions 91 and the concave portions 92 forming the waveform
may be a curved surface. Furthermore, the side wall and the upper frame may be continuous without forming a window between the long side wall and the upper frame.

According to the embodiment, the following effects can be achieved.

That is, as shown in FIG. 16, two bottle boxes Ha each having a recess 92 formed therein are joined by butting their side walls where the recess 92 is formed, and a bottle twice the size is placed on top of the two bottle boxes Ha. When the boxes Hb are stacked, the bottom rib 86a and bottom frame 89a of the bottle box Hb form the recess 92.
, the lower flange 90a is placed on the upper frames 79, 83 of the lower bottle box H, and the bottom part 85a is fitted into the upper opening of the lower bottle box H. Furthermore, when the same bottle boxes Ha are piled up in a pile, the bottom frame 89 is locked by the protrusion 91, so there is no risk of them slipping off.

Moreover, since the unevenness is formed only on one side of the long upper frame 83, the strength of the bottle box is not impaired.

Furthermore, since the convex part and the concave part are connected by an inclined surface, the upper bottle box can be slid and pulled out by simply lifting the front of the bottom of the upper bottle box, facilitating cargo handling operations.

(Effects of the invention) (1) An uneven part is formed on the upper surface of one of the long side walls, and the recessed part is formed on the extension line of the low rib and bottom frame that are perpendicular to the long side wall in a plane, and the concave part is formed on the upper surface of the adjacent short upper frame. Since the depth was formed to be the same as or deeper than the protruding height of the bottom rib and the bottom frame, the long upper frame sides on which the uneven parts were formed were butted and joined, and the upper part was made with a piece twice the size on the plane. When the bottle boxes are stacked, the bottom rib and bottom frame of the upper bottle box fit into the recess, and the bottom of the upper bottle box fits into the upper opening of the lower bottle box, allowing safe stacking.

(2) Since the uneven parts are continuous by the slope,
It can be easily pulled out by simply lifting the front of the bottom of the upper bottle box.
