Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a synthetic resin bottle box that can be connected to two bottle boxes facing each other in a detachable manner by operating a handle. This invention relates to a connectable synthetic resin bottle box with a firmly attached handle.

(Prior Art) Synthetic resin bottle boxes have conventionally been used to store and transport bottles for beer, soft drinks, etc. These synthetic resin bottle boxes generally have a lattice-like rib on the bottom, and a lattice-like partition wall between the side walls to separate and store the bottles.
There were 30 compartments, and bottles were stored in these compartments. These bottles and boxes are stored and transported in a stacked state.

However, when a large number of bottles are stored in one box, it is heavy and inconvenient to carry.

Therefore, in recent years, conventional bottle boxes have been split and molded into half the size to make them more compact, making them easier to carry, and the two split molded boxes can be connected together for storage. A bottle box with a structure that stabilizes the water has been proposed. For example, West German Patent Publication No.
No. 3034650 shows a bottle box that can be connected.

The connectable bottle boxes shown in the above-mentioned West German patent publication are formed into a rectangular shape in plan, with one side of the vertical side wall serving as an abutting surface, and a connecting hook provided on one of the supports adjacent to this abutting surface. ,
The other support has a double-walled structure with a hollow space inside, and has an insertion hole for the hook, and is equipped with a vertically movable connecting member inside.The hook is inserted into the hook insertion hole, and the hook The two bottle boxes are connected and fixed by engaging with a connecting member installed inside the double wall support.

The connecting member is raised and lowered by a handle attached to the upper edge of the bottle box. That is, when one end of the handle and the upper part of the connecting member engage and the handle is positioned horizontally, the connecting member rises to the uppermost end to connect the two bottle boxes, and the handle rotates. When it is moved to a vertical position, it is configured to release the engagement with the connecting member, so that the connecting member can be lowered to the lowest end and separated.

When connecting two bottle boxes with this type of configuration, hold the handles of the two bottle boxes hanging in both hands, butt the side walls of the two boxes together and face the respective hook insertion holes. Insert the hook of the bottle box and simply rotate both handles outward to connect them.

(Problem to be solved by the invention) Since a bottle box with such a structure is carried by hanging the handle, not only the handle itself but also the attachment part of the handle must have enough strength to withstand this. No.

However, the conventional handle mounting structure has a stud integrally protruding from the inside of the handle.
This stud is inserted into a mounting hole formed in the upper frame of the bottle box and is rotatably supported. Therefore, if you transport the handle with the handle suspended,
The studs bear all of the load of the bottle box, so if you lift it suddenly or apply strong force, the studs may break.

If the stud is damaged, the handle will no longer function properly, so not only will you be unable to carry it by holding it, but you will also be unable to move the connecting member up and down by rotating the handle.
It becomes impossible to use two bottle boxes connected together, which is a characteristic of this type of bottle box.

Furthermore, if the handle mounting structure does not have sufficient strength, there is a risk that the handle may fall during transportation or the handle may be damaged during transportation, causing the cargo to collapse.

Also, even if you try to stack these bottles of conventional size before connecting them and molding them separately, the bottoms of the conventional bottles are placed on the upper ends of the side walls that are butted against each other, and the top opening is Because they do not fit properly, stable stacking is not possible.

This idea was made in view of the above points,
The purpose is to provide a connectable synthetic resin bottle box that can be safely transported by making the attachment between the handle and the upper edge of the bottle box robust.

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

That is, one side of a vertical side wall of a rectangular bottle box with an open top is formed into a rectangular shape in a plan view, and one side wall adjacent to the butt surface is provided with a plurality of protruding hooks, and the other side is provided with a plurality of hooks protruding from one support. The pillar has a double wall structure with a hollow inside, and a plurality of hook insertion holes are formed on the abutting surface side of the external wall to penetrate the hollow, and the hollow is engaged with the hook. A vertically movable connecting member is attached, and a rotatable handle whose tip end engages with the upper part of the connecting member and fits on the outer surface of the upper frame is pivotally supported, and the upper frame has the same shape. When two bottle boxes are butted together, the other bottle box is inserted into the hook insertion hole of the other bottle, and this hook is engaged with a connecting member, whereby the two bottle boxes can be connected detachably. In the box, the upper surface of the longitudinal upper frame on the abutting surface side is formed into a wavy shape by a convex part and a concave part, the concave part is located on an extension line of the bottom rib perpendicular to the longitudinal side wall in a plane, and the short side of the concave part When the depth from the top of the frame is y and the protruding height of the bottom from the bottom flange is z, y
≧z, and furthermore, by protruding a boss part on the outer surface of the short upper frame, inserting the boss part into the handle mounting hole, and fitting a stud into the boss part to prevent the handle from falling off. It is characterized by a handle attached to it.

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

First, Fig. 1~ shows the bottle box H related to this invention.
This will be explained based on FIG.

The bottle box H is formed into a rectangular shape in a plane, with longitudinal side walls 5,
6. Connected by the short side walls 7 and 8, and further connected at the upper end by the long upper frames 10 and 11 and the short upper frames 12 and 13, and the part surrounded by the pillar, side wall, and upper frame is a window. It is set at 14.

Therefore, in this embodiment, the longitudinal upper frames 10, 11 and the shorter upper frames 12, 13 are used as handles.
The bottom part 15 of the bottle box H consists of a bottom frame 18 and a bottom rib 9, and the bottom frame 18 is connected to the upper frames 10, 11, 12 and 1.
The bottom ribs 9 are provided in the bottom frame 18 in a lattice pattern so as to protrude from the lower ends of the support column 14 and the side walls 5 to 8 so as to be located inside the inner surface of the bottom frame 18 in a plane. Inside the bottle box H, a compartment 17 is formed by a grid-like partition wall 16 to separate and store the bottles. Furthermore, the side walls 5 to 8
A lower flange 19 is provided protruding from the outer surface of the lower end.

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 longitudinal upper frame 10 will be explained.

The upper surface of the longitudinal upper frame 10 is formed into a wave shape. The depth of the upper surface of the longitudinal upper frame 10, that is, the depth of the protrusion 10a from the upper surface of the shorter upper frames 12 and 13 is x, and the depth of the recess 10b is y. x<z≦y, where z is the height of the protrusion of the bottom 15 from the lower surface of the lower flange 19,
Preferably x<(1/2 to 3/4)z. and,
It is desirable that the inclined surface 10c be an inclined surface with a slope as gentle as possible.

Further, the wave-shaped recess 10b is formed in a size such that the bottom rib 9 fits on an extension line of the bottom rib 9 which is perpendicular to the longitudinal side walls 5, 6 in a plane. Therefore,
When two bottle boxes H are placed side by side and a bottle box twice the size is stacked, the bottom rib of the upper bottle box fits into the recess 10b. The convex portion 10a and the concave portion 10b are continuous by an inclined surface 10c.

In addition, the upper surface shape of the longitudinal upper frame 10 is a wave shape,
In order to facilitate pulling out during loading and unloading, the protrusion 10a is formed lower than the upper surfaces of the short upper frames 12 and 13 by x, but the upper surface of the protrusion 10a is on the same plane as the short upper frames 12 and 13, i.e. , x may be set to 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 the materials are stacked in so-called sticks, the bottom frame 18 is locked by the protrusion 10a, allowing safe stacking.

In addition, two bottle boxes are connected with their longitudinal side walls 5 facing each other, and the same lattice-like bottom ribs are formed on the upper tier.
When bottle boxes of twice the size are stacked, the bottom rib of the upper bottle box 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 10 of the longitudinal upper frame 10
b are connected by the inclined surface 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, you can smoothly pull it out without getting caught. can.

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 side of the longitudinal side wall 5, which is the abutting surface of the support 1, is recessed by the same dimension as the abutting surface 43 of the longitudinal side wall 5, and has L-shaped hooks 31, 32 in a plane.
and 33 are provided to protrude outward. Hook 3
The protruding dimensions of 1, 32, and 33 are 1 to 2 times, preferably approximately 2 times, the concave dimension of the abutting surface of the support column 1.
Multiply that by 2.

On the other hand, the support column 4 forms a substantially triangular space 36 between the inner wall 34 and the outer wall 35. It has a so-called double wall structure, and the surface on the side of the longitudinal side wall 5, which is the abutting surface of the external wall 35, protrudes from the abutting surface 43 of the longitudinal side wall 5 by the size of the recess of the abutting surface of the support column 1. 35 and the hooks 31, 32, and 33 protruding from the support 1 are on the same plane.

Furthermore, insertion holes 37, 38, and 39 into which the hooks 31, 32, and 33 can be inserted when connected are formed in the abutting surface of the external wall 35. Further, a small hole 40 into which a positioning protrusion of a connecting member to be described later fits is bored in the short side wall 8 of the outer wall 35 (see FIG. 4).

The upper surface of the cavity 36 is closed, but the lower surface is open so that a connecting member can be inserted, and the cavity 36 is closed.
The upper part has an insertion hole 44 into which the end of the handle can be inserted.
is formed. A guide rib 42 for guiding the connecting member is provided on the inner surface of the abutting surface of the outer wall 35 in a protruding manner. The guide rib 42 is connected to the insertion hole 3.
7, 38, and 39, and its lower end 42a is at a height such that the bottom plate of the connecting member does not touch when the connecting member rises and reaches the uppermost end, preferably between the bottom plate of the connecting member and the lower end 42a. They are formed at heights with an interval of 1 to 2 mm (see FIGS. 1 and 3).

FIG. 5 is an explanatory perspective view with a part omitted of the bottle box body with the handle removed, and FIG. 6 is a perspective view of the handle.

A locking projection 45 is protruded near the corner of the outer surface of the upper edge of the longitudinal upper frame 11.
A gap 47 is formed between the upper edge flange 46 and the lower end rib of the handle, which will be described later.

A boss portion 48 for attaching a handle is protruded on the outer surface of the short upper frames 12 and 13.
The length of the handle is equal to or smaller than the width of the handle. Furthermore, a rib 49 with an inclined surface 49a on the support 1 side is provided on the lower end outer surface of the short upper frames 12, 13, and this rib 49 and the upper edge flange 4
6 is defined as a recessed portion 49b. The width of the recess 49b is approximately the same as the width of the handle, and its center perpendicular line approximately coincides with the center perpendicular line of the attachment hole of the handle.

In this way, when the rib 49 and the recess 49b are formed, together with the action of the locking protrusion 45, the fitted state of the handle can be maintained more reliably. 49b and is difficult to fall over.

Reference numeral 70 denotes a handle attached to the outer surface of the upper frame.Boss portions 79 are protruded from both ends of the handle 70, and a boss hole 72 of the boss portion 79 connects to a boss portion 78 protruding from the short side upper frame. It is sized to be inserted. A pinion-shaped tooth 7 is provided at one end of the handle 70.
5 is provided and is configured to mesh with the rack-shaped teeth 54 of the connecting member 50 when inserted into the cavity 36 of the post 4.

Furthermore, the outer surface of the corners and the vicinity thereof, where the handle 70 is most easily caught, is a smooth surface 76, and ribs 77, 78 are provided protruding from the upper and lower ends of the inner surface of this smooth surface 76.

FIG. 7 is a perspective view of the stud, and FIG. 8 is a sectional view showing how the handle and the upper frame of the bottle box are attached.

The stud 80 has a locking plate 82 at one end of an insertion section 81 inserted into the boss section 48 and a flange 8 at the other end.
3, and the front surface of the flange 83 has an inclined surface 84 for easy insertion, and a slit 85 is formed together with a part of the insertion portion 81. The locking plate 82
The outer diameter of the flange 83 is larger than the inner diameter of the boss hole of the boss portion 48 into which the flange 83 is inserted, and the locking plate 82 is particularly large enough to prevent the handle 70 from falling off.

To attach the handle 70, as shown in FIG.
is inserted into the boss hole of the boss portion 48 from the outside of the bottle box toward the inside and fixed.

In this way, the handle 70 is configured to fit into the boss portions 48 of the upper frames 12 and 13, and the stud 80 is inserted into the boss hole, so the load of the bottle box is not applied to the studs and is integrated with the upper frame. A robust mounting structure can be achieved by using the boss portion 48 that protrudes from the top.

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

As shown in FIGS. 9 to 11, the structure of the connecting member 50 is that the upper part of the slide plate 51 is cut to form a recess 52, and the upper plate 5 facing upward is inserted into the recess 52.
3 is followed by a lock-shaped tooth 54. On the rear surface of the slide plate 51, claws 55, 5 are provided in a right angle direction.
6 and 57 are provided protrudingly, and a back plate 60.61 is provided in succession in the same direction at the bottom of the pawls 55, 56, and a horizontal reinforcing plate 6 is provided on this back plate 60.61.
2,63 are provided. This back plate 60.6
1 is guided in contact with the guide rib 42.

Furthermore, a substantially triangular bottom plate 64 having a shape substantially similar to the shape of the hollow 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 and 33 are inserted into the hook insertion hole 3.
7, 38, and 39, respectively, and the empty 36
When the connecting member 50 inserted therein is raised, the pawls 55, 56 and 57 connect to the hooks 31, 32 and 33.
configured to engage with.

Reference numeral 65 denotes a positioning flexible piece formed on the side surface of the connecting member 50. The positioning flexible piece 65 is separated on three sides by a notch 66, and has a protrusion 67 formed at its lower end. When the positioning flexible piece 65 is pushed down to the lowest position within the cavity 36, the projection 67 is inserted into the small hole 40 formed in the outer wall 35 of the support column 4.

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, by rotating the handle 70 and rotating the grip portion upward, the pinion-shaped teeth 76 at the ends and the rack-shaped teeth 54 of the connecting member 50 are connected. Release the engaged state,
Pinion-shaped teeth 75 are directed downward. When the connecting member 50 is pushed down by the pinion-shaped teeth 75 to release the meshing state between the two, the protrusion 67 of the flexible piece 65 for positioning the connecting member 50 that has been pushed down while pressing the inner surface of the external wall 35 is small hole 4
0 is fitted. By fitting the projection 67 into the small hole 40, the connecting member is held without inadvertently moving up and down.

When the protrusion 67 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. Next, while holding the handle 70, squeeze the longitudinal side wall 5, that is, the abutting surface 43, and rotate the grip portion of the handle 70 outward, so that the hook is inserted into the hook insertion hole sequentially from below. Furthermore, since the upper portions of the bottle boxes are pressed against each other by the rotation of the handle 70, the two bottle boxes can be joined even more tightly.

As the handle 70 rotates, the pinion tooth 75 at the tip of the handle 70 and the rack tooth 54 at the top of the connecting member 50 mesh with each other, and the connecting member 50 gradually rises until the handle 70 becomes horizontal. To,
The connecting member is pulled up to the top.

When the connecting member 50 is pulled up, 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, and the claw 5
5, 56, and 57 are inserted inside the hooks 31, 32, and 33, and the two bottle boxes H are completely connected.

To separate two connected bottle boxes, use the handle 7.
0 to release the engagement between the connecting member 50 and the handle 70, the connecting member is pulled down and the pawls 55, 56, 57 and the hook 31,
Since the engagement state with 32 and 33 is also released, it is only necessary to separate the two bottle boxes.

(Effect of the invention) As described above, according to the synthetic resin bottle box of this invention, since the longitudinal upper frame on the abutting surface side is formed in a wavy shape, two bottle boxes can be connected and the pre-divided bottle can be placed on top of it. It is possible to stably stack bottle boxes twice the size of conventional ones.

In addition, the handle is attached to the top frame of the bottle box by fitting into the boss part that is integrally provided on the top frame, and the stud is simply provided to prevent the handle from falling off, so when the handle is hung, The load is applied to the boss and not to the stud.

Therefore, the handle attachment part can sufficiently withstand a large load, allowing safe transportation, and has great practical effects, such as being able to be used for a long period of time as a connectable bottle box.
