Description

[Detailed description of the invention] (Industrial application field) This invention relates to a synthetic resin bottle box that can be detachably connected to each other with two bottle boxes facing each other. This invention relates to connectable synthetic resin bottle boxes on which conventional sized bottle boxes can be stacked and which prevents the engagement state of a handle for vertically moving a connecting member from being released inadvertently.

(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) In a bottle box having such a configuration, when the connecting member is fitted horizontally to the upper edge of the bottle box, when an impact is applied to the handle, the fitting state is changed. If it is released carelessly, there is a risk that the two bottle boxes will not be able to maintain their connection. If the connected state cannot be maintained, one of the bottle boxes may fall or cause an unexpected accident.

Moreover, when the bottle box is molded separately into two parts, 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 was not split and formed on top of these bottles, the bottoms of the conventional bottle boxes will not meet the side walls that were 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 above points,
Its purpose is to allow bottle boxes of the original size before division to be stacked, and to connect them so that the handle that moves the connecting member up and down will not be accidentally released. The purpose is to provide a synthetic resin bottle box.

(Means for Solving the Problems) In order to achieve the above object, this invention has the following structure.

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 engages with the upper part of the connecting member is pivotally supported on the upper frame, and two bottle boxes of the same shape are butted against each other. At this time, insert the other hook into the hook insertion hole of one bottle box,
In the bottle box in which two bottle boxes can be detachably connected by engaging the hook and the connecting member, the upper surface of the upper frame on the abutting surface side is formed into a wave shape by a convex part and a concave part, and the concave part is located on the extension line of the bottom rib perpendicular to the longitudinal side wall in a plane, the depth from the upper surface of the short upper frame is y, the protrusion height of the bottom from the lower flange is z, and y≧z,
Furthermore, the hook is formed into a substantially L-shape in plan, and the connecting member is provided with a pawl that is inserted into and engaged with the hook, and the hook is provided at a corner of either the outer surface of the upper frame or the inner surface of the handle, or It is characterized in that a locking protrusion is formed in the vicinity, and a locking rib or recess that engages with the locking protrusion is formed on the other side.

(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 grid-like partition wall 16 to separate and store the bottles. Furthermore, the side wall 5
A lower flange 19 is provided protrudingly 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.
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 orthogonal 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, ie, 2l.

On the other hand, the support column 4 has a so-called double wall structure in which a substantially triangular space 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 protrudes from the abutting surface 43 of the longitudinal side wall 5 by the recess dimension 1 of the abutting surface, and therefore, the external wall 35 and the hooks 31, 32, and 33 protruding from the support column 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 formed on the short side wall 8 side 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 protruded from the inner surface of the outer wall 35 on the abutting surface side. The guide rib 42 is connected to the insertion hole 3.
7, 38, and 39, and its lower end 24a 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 24a. (See Figures 1 and 3).

Figures 5 to 7 show an embodiment of this invention,
Fig. 5 is an explanatory perspective view with a part of the main body of the bottle box omitted with the handle removed, Fig. 6 is a perspective view of the handle, and Fig. 7 is a cross section showing the state of engagement between the handle and the upper edge of the bottle case. It is a diagram.

As shown in FIG. 5, the short upper frame 12 of the bottle box H,
A locking rib 45 is provided protruding from the outer surface of the upper edge of 13.
Further, protrusions 46 are provided protruding near the corners.

On the other hand, the short upper frames 12 and 13 of the handle 70
A locking projection 76 located at the lower end of the locking rib 45 is protruded on the inner surface in contact with the locking rib 45, and a recess 7 into which the projection 46 fits is provided near the corner.
7 is formed. When the handle 70 is attached to the bottle box H and fitted horizontally to the outer surface of the upper edge, the locking protrusion 76 engages with the lower surface of the locking rib 45 of the short upper frame 12, 13. At the same time, the protrusion 46 of the short upper frame and the recess 77 of the handle fit together.

Further, the handle 70 is rotatably supported by the short upper frames 12 and 13 by inserting a pin 74 into the mounting hole 72, and one end is inserted into the hollow 36 of the support column 4, and a connecting member (described later) is attached to the end. 50 easy-shaped teeth 5
Pinion-shaped teeth 75 are provided which mesh with 4.

In this embodiment, a locking rib 45 is provided protrudingly on the short upper frame, which is less likely to deform, and a recess is formed near the corner, so that even if the handle is caught and receives some impact, the handle will not move. It is possible to prevent the fitted state from being unintentionally released.

Figures 8 to 12 show other embodiments, Figure 8 is an explanatory perspective view of the bottle box body with the handle removed, Figure 9 is a perspective view of the handle, and Figure 10 is a top view of the handle and bottle box. FIG. 6 is a cross-sectional view of the edge in a locked state.

As shown in FIG. 8, a locking protrusion 46a is provided protruding near the corner of the outer surface of the upper edge of the longitudinal upper frame 11. A gap 47 is formed in which the lower end rib of the handle engages. In addition, short upper frame 1
The outer surface of the lower end of 2, 13 has an inclined surface 48a on the support 1 side.
A rib 48 is provided, and a recess 49 is formed between the rib 48 and the upper edge flange 41, which is approximately the same width as the handle.

In this way, when the rib 48 and the recess 49 are formed, together with the action of the locking protrusion 46a, the engaged state of the handle can be maintained more reliably. 49 and does not easily fall down.

The handle 70 has ribs 80, 81, 82, 83 protruding from the upper and lower ends of its inner and outer surfaces, respectively, and has a cross section of approximately I.
It is formed into a letter shape. When the handle 70 is attached to the bottle box H and fitted horizontally to the outer surface of the upper edge, the handle 70 is attached to the lower surface of the projection 46a of the longitudinal upper frame 11.
A rib 83 protruding from the lower end of the inner surface is configured to engage with the rib 83.

Figures 11 and 12 show another embodiment of the handle; in the previous embodiment, ribs were formed over the entire inner and outer surfaces, whereas in this embodiment, ribs were formed on either the inner or outer surfaces. This is what I did.

That is, the outer surface is a smooth surface 84 at the corner where the handle is most likely to get caught, and in the vicinity thereof;
Conversely, ribs 81 and 83 are formed on the back surface of this smooth surface 84, and ribs 80 and 83 are formed on the outer surface in other parts.
82, and the back surface was made smooth.

In this way, when the corners and the vicinity thereof are made smooth, it is possible to prevent the handle from being caught and the fitted state being inadvertently released.

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

As shown in FIGS. 6 and 7, 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. At the rear end of the slide plate 51, there is a pawl 5 perpendicular to the axial direction.
5, 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. At the bottom of the claws 55, 56 are rear plates 60, 61.
are arranged in succession in the same direction, and this back plate 60,
Horizontal reinforcing plates 62 and 63 are provided on the top of 61. The back plates 60 and 61 prevent rattling within the space 36 and are guided in contact with the guide ribs 42. Further, a triangular bottom plate 64 having substantially the same shape as the hollow 36 of the support column 4 is integrally provided at the lower part of the tab 57. Bottom plate 64 is empty
36 to prevent foreign matter from entering.

Hooks 31, 32, 33 are inserted into hook insertion holes 37,
38 and 39 respectively, and when the connecting member 50 inserted into the cavity 36 is raised, the pawl 5
5, 56 and 57 are configured to engage with hooks 31, 32, 33. Therefore, it is preferable that the inner surfaces of the pawls 55, 56, and 57 be sloped surfaces that gradually become thicker toward the bottom. In this way, when the inner surfaces of the tabs 55, 56, and 57 are made into sloped surfaces, there is no looseness in the engaged 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 outer surface of the lower end. Flexible piece for positioning 6
When the support column 5 is pushed down to the lowest position within the space 36, the protrusion 67 is fitted 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, rotate the handle 70 and lift the grip part 20 upward, and then connect the hook-shaped teeth 54 of the connecting member 50 and the handle 7.
0, and the hook insertion holes 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 the connecting member 50 is held without inadvertently moving up and down.

Next, the longitudinal side walls 5, that is, the abutting surfaces 43 are butted against each other, and the hook insertion holes 37, 38 and 39 are inserted into the hook insertion holes 37, 38 and 39.
Insert hooks 31, 32 and 33 into the holes, respectively. In this state, if the grip portion 20 of the handle 70 is rotated downward and the tip is raised, the handle 70
The pinion-shaped tooth 75 at the tip of the connecting member 50 meshes with the rack-shaped tooth 54 at the upper part of the connecting member 50, and the connecting member 50 gradually rises as the back plates 60, 61 are guided by the guide ribs 42, and the handle 70 becomes horizontal. At this point, the connecting member is pulled up to its uppermost position.

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 14-15).

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, a locking protrusion is provided protrudingly on the outer surface of the upper frame that contacts the handle, and a recess or a recess that fits with the protrusion is provided on the inner surface of the handle. Since the ribs are formed to engage with the protrusions, they fit or engage with each other, and the fitted state between the handle and the upper frame will not be released even with some impact.

Therefore, the two bottle boxes can be safely transported and stored while being connected.

On the other hand, since the bottle box body and the handle are made of synthetic resin, they are flexible, and by lifting the grip portion 20 by hand, the fitted state of the two can be released.
