Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a synthetic resin bottle box that can be removably connected to two bottle boxes facing each other. This invention relates to a connectable synthetic resin bottle box with a hook protruding from the bottom.

(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 into half the size to make them more compact, making them easier to carry, and the two split-molded bottles can be interconnected 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 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.

(Problems to be Solved by the Invention) The connecting hook in the above configuration projects downward and engages with the recess of the connecting member. Therefore, in order to ensure the engagement between the hook and the recess, it is necessary to increase the amount of downward protrusion of the hook, but increasing the amount of protrusion not only increases the risk of breakage, but also makes the corresponding recess larger. It is also difficult to form. Further, the insertion hole into which the hook is inserted is provided with sufficient clearance to facilitate insertion of the hook. For this reason, when two bottle boxes are connected, the clearance between the hooks and the hook insertion holes is large, and the looseness between the hooks and the hook insertion holes becomes correspondingly large. If there is a lot of looseness between the two when connected in this way, it may cause damage to the hook during storage or transportation.
In addition, since stable stacking is not possible, there is a risk of the cargo collapsing, making it impossible to perform safe work.

Furthermore, if you try to connect two split-molded bottle boxes and stack a conventional bottle box of the original size before splitting on top of this, the bottom of the conventional bottle box will be placed on the top of the side wall. There is a problem that stable stacking is not possible.

This idea was made in view of the above points,
The purpose is to have enough clearance when inserting the hook so that it is easy to insert, but after the hook is inserted and the connection is completed, there is almost no clearance between it and the insertion hole, so the hook has a structure that does not cause rattling. The purpose of the present invention is to provide a connectable synthetic resin bottle box that can be safely transported and stored.

(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. When a connecting member is attached and two bottle boxes of the same shape are butted against each other, insert the hook of the other bottle into the hook insertion hole of one bottle box,
In a bottle box in which two bottle boxes can be detachably connected by engaging the hook with a connecting member, the upper surface of the longitudinal upper frame on the abutting surface side is formed into a wave shape by a convex portion and a concave portion, When the recess 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, and the protrusion height of the bottom from the lower flange is z, y≧z. None, and 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 height of the hook is directed toward the tip rather than the base. It is characterized in that it is gradually made smaller so that the upper and lower surfaces are sloped surfaces, and that the hook insertion hole is slightly larger than or almost the same size as the root of the hook.

(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 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. 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=O.
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, 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 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.

5 and 6 are a cross-sectional view and a perspective view showing the hook and the hook insertion hole, and show the hooks 31, 32.
The heights of and 33 are formed to be gradually smaller toward the tip than that at the root, and the upper and lower surfaces are sloped surfaces. That is, the height of the base of the hooks 31, 32, and 33 is T, and the height of the tip is t.
Then, t<T. The heights of the hook insertion holes 37, 38, and 39 are formed so that there is almost no clearance between them and the base of the hook, and are slightly larger than or approximately the same as the height of the base of the hook. If the height of the insertion hole is T', then T≦T'.

Therefore, it is easy to insert the hook, and
Once the hooks are inserted and the two bottle boxes are connected and fixed, the hooks 31, 32, 33 and the hook insertion hole 3
Since there is no play between the hooks 7, 38, and 39, transportation and storage operations can be carried out safely, and the hooks will not be damaged.

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 abutting surface of the outer wall 35 is recessed by the size l of the abutment surface of the support column 1. The hooks 31, 32 and 3 protrude beyond the abutting surface 43 of the side wall portion, and therefore protrude from the outer wall 35 and the support column 1.
3 is the same surface.

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. 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 wall 35. (See Figure 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.
An insertion hole 42 is formed in the upper part of the handle, into which the end of the handle can be inserted while rotating.

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

As shown in FIGS. 7 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 rack-shaped tooth 54, and the rear surface of the slide plate 51 has pawls 55, 56 and 57 protruding in the right angle direction.

More specifically, the lock-shaped tooth 54 has a recess 52.
A reinforcing plate 58 is integrally formed on one side of the rack-shaped tooth 54.
Back plates 60 and 61 are provided in succession in the same direction at the bottom of the claws 55 and 56, and these back plates 60 and 61
Horizontal reinforcing plates 62 and 63 are provided on the upper part of the frame. In addition, the lower part of the pawl 57 is provided with the space 3 of the support 4.
A substantially triangular bottom plate 64 having substantially the same shape as 6 is integrally provided.

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 engaged 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 lower surface of its lower end. When the positioning flexible piece 65 is pushed down to the lowest position within the gap 36, the protrusion 67
is configured to be inserted into a small hole 40 bored in the outer wall 35 of the support column 4.

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 cavity 36 of the post 4 through the insertion hole 42, and the end is provided with pinion-shaped teeth 75 that mesh with the rack-shaped teeth 54 of the connecting member 50.

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 to release the engaged state of the handle 70 of the connecting member 50, and then insert the hook insertion holes 37, 38 and 39. fully open. When the connecting member 50 is pushed down to completely release the engaged state, the protrusion 66 of the flexible positioning piece 65 of the connecting member 50 that has been pushed down while pressing the inner surface of the external wall 35 fits into the small hole 40. be done. By fitting the projection 66 into the small hole 40, the connecting member is held without inadvertently moving up and down.

Next, the longitudinal side walls 5, that is, the butting surfaces 43 are butted against each other, and the hook insertion holes 37, 38, and 39 are inserted.
Insert hooks 31, 32 and 33 into the holes, respectively. In this state, if the grip part 20 of the handle 70 is rotated downward to raise the tip, the pinion-shaped teeth 75 at the tip of the handle 70 and the rack-shaped teeth 54 at the upper part of the connecting member 50 will mesh and connect. As the member 50 gradually rises and the handle 70 becomes horizontal, 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
will be completely connected (see Figures 12 and 13).

To separate the two connected bottles, rotate the handle 70 to release the engagement between the connecting member 50 and the handle 70, the connecting member will be pulled down, and the claws 55, 56, 57 and the hook 31 will be pulled down. ,3
Since the engagement state with 2 and 33 is also released, it is only necessary to separate the two bottle boxes.

The bottle box according to this invention is not limited to the above structure, but may have a double-walled structure in which all four corner supports have voids inside, and the connecting member can be raised and lowered by turning the handle. Instead of the mechanical engagement, the structure may be such that the operating protrusion of the connecting member protruding from the external wall is moved up and down.

(Effect of the invention) As described above, according to the synthetic resin bottle box of this invention, the height of the connecting hook is gradually reduced from that at the base toward the tip, and the upper and lower surfaces are sloped. Since the hook insertion hole is made to have a height that is slightly larger than or approximately the same as the base of the hook, the following specific effects can be achieved.

In other words, since there is sufficient clearance between the tip of the hook and the hook insertion hole, not only can two bottle boxes be easily connected, but also the base of the hook and the hook insertion hole can be easily connected after connection. Since there is almost no clearance between them, there is no backlash and transport and storage operations can be carried out safely. Furthermore, since there is no backlash, damage to the hook can be prevented.

Furthermore, by connecting two bottle boxes of this invention, it is possible to stably stack a bottle box twice the size of the conventional bottle box before division.
