Description

[Detailed description of the invention] (Industrial application field) This invention relates to a synthetic resin bottle box that can be detachably connected to two bottle boxes facing each other, and in particular, the connecting member can be moved up and down. This invention relates to a connectable synthetic resin bottle box whose handle is prevented from being accidentally caught.

(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 void inside, and is provided with 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 Both bottle boxes are connected and fixed by engaging 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 top 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 moved to a vertical position, the coupling member is disengaged from the coupling member, and the coupling member is 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.

(Problems to be Solved by the Invention) The bottle box having such a structure is manufactured from synthetic resin, and the handle for raising and lowering the connecting member is also manufactured from synthetic resin. Since the handle is used to hang and carry the bottle while it is stored, it must be strong enough to withstand this. On the other hand, it is known that increasing the thickness of a synthetic resin not only increases manufacturing time but also causes deformation. Therefore, in general, reinforcing ribs are formed at the upper and lower ends in order to reduce the wall thickness to prevent deformation and at the same time to provide strength.

Reinforcing ribs are usually provided protruding from the outer surface of the handle, but if the ribs are provided protruding from the outer surface, the ribs may get caught and cause an unexpected accident. For example, in the bottle filling process, when the bottles are transferred horizontally on an inclined conveyor, the handles of the front and rear bottle boxes may get caught, and there is a risk that the two bottle boxes will become disconnected and unable to maintain their connected state.

When a conventional bottle box is divided into two halves, side walls are naturally formed in the divided parts. 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 formed separately on top of these bottle boxes, the bottom steps of the conventional bottle boxes will not meet the side walls that were butted against each other. Because they are placed on the top edge of the stack and do not fit into the top opening, stable stacking is not possible.

This idea was made in view of the above points,
The purpose of this is to prevent the handle, which is pivoted on the upper edge of the bottle box and moves the connecting member up and down, from being accidentally pulled up if it gets caught during transportation or storage, and to stack it with conventional bottle boxes before division. It is an object of the present invention to provide a connectable synthetic resin bottle box.

(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 support column has a double wall structure with an internal gap, and a plurality of hook insertion holes are formed on the abutting surface side of the external wall to penetrate the gap, and the gap is movable up and down to engage with the hook. A connecting member is attached to the upper frame, and a rotatable handle whose tip end engages with the upper part of the connecting member is pivotally supported, so that when two bottle boxes of the same shape are butted against each other, one side Insert the other hook into the hook insertion hole of the bottle box,
In the bottle box in which two bottle boxes can be detachably connected by engaging the hook and the connecting member, the top surface of the upper frame on the abutting surface side is formed in a wave shape with a convex part and a concave part, and the concave part is formed on the extension line of the bottom rib and bottom frame perpendicular to the long side wall in a plane, and the depth from the top surface of the adjacent short side upper frame is y,
When the protrusion height of the bottom from the lower flange is z, y≧z, a locking protrusion is formed at or near the corner of the outer surface of the upper frame, and the handle has a smooth outer surface at the corner and its vicinity. It is characterized in that the inner surface is provided with a protruding rib that engages with the locking protrusion, and the other portions are provided with ribs protruding from the outer surface, and the inner surface is made smooth.

(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 when viewed from above, and the 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 14 It is said that

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 protrude from the lower ends of the support columns 1 to 4 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 lattice-like partition wall 16 to separate and store the bottles. Furthermore, the side wall 5
A lower flange 19 is provided protruding from the outer surface of the lower end portion of .

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 short upper frame 1
The depth of the convex portion 10a from the top surface of 2, 13 is x, the depth of the recess 10b is y, and the height of the protrusion of the bottom 15 from the bottom surface of the lower flange 19 protruding from the lower end of the side wall is z. Then, 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.

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 stacking so-called sticks, the bottom frame 18 has a convex 1
0a allows for 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, the upper bottle box can be pulled out smoothly without getting caught by simply lifting the bottom of the front side slightly. 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 column 1 is recessed by a dimension l from the abutting surface 43 of the longitudinal side wall 5, and has L-shaped hooks 31 and 32 in the 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 l of the abutting surface of the support 1.
Double that, 2l.

On the other hand, the support column 4 has a so-called double wall structure in which a substantially triangular gap 36 is formed between the inner wall 34 and the outer wall 35, and the surface on the longitudinal side wall 5 side, which is the abutting surface of the outer wall 35, is the support column 1. It protrudes from the abutting surface 43 of the longitudinal side wall 5 by the concave dimension l of the abutting surface, and therefore, the external wall 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 into the cavity 36.
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 41 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 41. They are formed at heights with intervals of 1 to 2 mm (see Figures 1 and 3).

FIG. 5 is an explanatory perspective view with a part omitted of the bottle case body with the handle removed, FIG. 6 is a perspective view of the handle, and FIGS. 7 and 8 are cross-sectional views of the handle.

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

Furthermore, a rib 48 having an inclined surface 48a on the support 1 side is provided on the outer surface of the lower end of the short upper frames 12, 13, and a recess 49 is formed between the rib 48 and the upper flange 46. The width of the recess 49 is approximately the same as the width of the handle, and its center line approximately coincides with the center line of the attachment hole of the handle. In this way, when the locking protrusion 45 is provided protrudingly, the fitted state of the handle can be maintained even more reliably, and when the handle is stood vertically, it fits into the recess 49 and is less likely to fall. . However, the rib 48 and the recess 49
The formation of may be omitted if necessary.

A handle 70 is attached to the outer surface of the upper frame, and the handle 70 is rotatably supported by the short upper frames 12 and 13 by inserting a pin 74 into a mounting hole 72. One end of the handle 70 is inserted into the insertion hole 4 of the column 4
4 into the cavity 36, and the end thereof is provided with pinion-shaped teeth 75 which mesh with the rack-shaped teeth 54 of the connecting member 50.

Further, the outer surface of the corner and the vicinity thereof where the handle 70 is most easily caught is a smooth surface 76, and ribs 77 and 78 are provided protruding from the upper and lower ends of the inner surface of this smooth surface 76. The grip portion 20 has ribs 80 and 81 protruding from its outer surface, a reinforcing member 85 is wound around it, and furthermore ribs 82 and 83 are protruded from the portion where the attachment hole 72 is formed. Therefore, the grip portion 20 and the attachment hole 72 have a structure opposite to that of the corner and its vicinity.

In this way, when ribs are provided on the outer surface of the grip, sufficient strength can be maintained even if the reinforcing member is wound with a certain distance between the ends without butting each other to save material. be able to.

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 the right angle direction.
6 and 57 are provided in a protruding manner, and rear plates 60 and 61 are connected to the lower portions of the claws 55 and 56 in the same direction. These back plates 60, 61 are connected to the guide ribs 42.
You will be guided by the

Further, a substantially triangular bottom plate 64 having a shape substantially similar to the shape of the gap 36 of the support column 4 is integrally provided at the lower part of the pawl 57 . In this way, when the shape of the bottom plate 64 is made almost the same as that of the gap 36 and the size is such that there is almost no gap, the gap 36 is
4, the air gap 36
It is possible to prevent foreign objects such as pebbles from entering the interior. In this seed bottle box, the bottom of the cavity 36 is open for inserting the connecting member, so preventing foreign matter from entering is important for smooth lifting and lowering of the connecting member.

The claws 55, 56 and 57 are the hooks 31, 32,
It is preferable that the inner surface that joins with 33 is an inclined surface that gradually becomes thicker toward the bottom. in this way,
When the inner surfaces of the pawls 55, 56, and 57 are 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 formed on the side surface of the connecting member 50. The flexible piece 65 for positioning is separated on three sides by a notch 66, and a protrusion 67 is formed on the lower surface of the lower end. Flexible piece for positioning 6
5 is configured such that when pushed down to the lowest position within the cavity 36, the protrusion 67 is inserted into the small hole 40 formed in the outer wall 35 of the 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, rotate the handle 70 to lift the grip part 20 upwards, and then connect the rack teeth 54 of the connecting member 50 and the handle 7.
The coupling member 50 is pushed down by the engagement with the pinion-shaped teeth 75 of 0, and the hook insertion hole 37,
38 and 39 are completely opened.

When the connecting member 50 is pushed down, the protrusion 67 of the flexible positioning piece 65 fits into the small hole 40 and is held without inadvertently moving up and down.

Next, the longitudinal side walls 5 are butted together and the hooks 31 and 3 are inserted into the hook insertion holes 37, 38 and 39, respectively.
Insert 32 and 33. In this state, handle 7
If the grip part 20 of the handle 70 is rotated downward and the tip is raised, the pinion-shaped teeth 7 at the tip of the handle 70 will be removed.
5 and the hook-shaped teeth 54 on the upper part of the connecting member 50 mesh with each other, and the connecting member 50 gradually rises while being guided by the guide ribs 42 of the back plates 60 and 61, and the handle 7
When 0 becomes horizontal, the connecting member is pulled up to the top.

At this time, pawls 55, 56, and 57 are hook 3.
Inserted inside 1, 32, 33, two bottle boxes H
are completely connected (see Figures 12-13).

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.

(Effects of the invention) As described above, according to the synthetic resin bottle box of this invention, the corners where the handle is most likely to get caught and the outer surface near the corners are made smooth, so there is no need to worry about accidental damage during transportation or storage. It can be transported and stored safely without getting caught.

Furthermore, since reinforcing ribs are provided on the inner surface at the corners and on the outer surface at areas other than the corners, the handle can maintain sufficient strength.

Further, since the locking projections are provided at the corners of the upper frame, they engage with the corners of the handle, and the handle is securely held on the outer surface of the upper frame. In addition, when the longitudinal upper frame sides with the uneven portions are butted against each other and bottle boxes twice the size in plane are stacked on the upper tier, the bottom ribs and bottom frame of the upper tier bottle boxes fit into the recessed portions. The bottom of the upper bottle box fits into the upper opening of the lower bottle box, allowing safe stacking.
