Description

[Detailed description of the invention] (Industrial application field) This invention relates to a synthetic resin bottle that can be removably connected to two bottle boxes facing each other, and particularly relates to a hook of the other bottle box. This invention relates to a connectable synthetic resin bottle box in which connecting members can be moved up and down smoothly.

(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 divided into half the size to make them more compact, making them easier to carry, and the two split-formed bottle 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-wall 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, and the hook is inserted into the hook insertion hole, and the hook is connected to 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) In a bottle box having such a configuration, in order to ensure the connection, it is necessary for the connecting member to move up and down smoothly. However, since the connecting members in conventional bottle boxes are rod-shaped bodies, they are heavy and difficult to move smoothly, and it is also difficult to hold them at predetermined positions at the upper and lower ends.

This idea was made in view of the above points,
The purpose is to reduce the weight of the connecting member, prevent deformation, and provide a connectable synthetic resin bottle box that can be moved up and down smoothly.

(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 and fits on the outer surface of the upper frame is pivotally supported, and two of the same shape are attached. When the bottle boxes are butted together, the hook of one bottle box is inserted into the insertion hole of the other bottle box, and the hook and the connecting member are engaged with each other, thereby allowing the two bottle boxes to be removably connected. A guide rib for guiding the connecting member is formed on the inner surface of the double wall column, and the lower end of this guide rib is formed at a height so that the bottom plate of the connecting member does not touch when the connecting member rises, and a connecting position confirmation hole is formed on the side surface. Further, the connecting member has a substantially U-shaped cross section having a rib with a slit and a back plate, and a confirmation display section that is displayed in the connection position confirmation hole is provided on the lower side surface, and furthermore, The member is characterized in that it has a bottom plate having a similar shape to the gap and having a size that almost closes the gap.

(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 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. Letting z be the height of the protrusion of the bottom 15 from the lower surface of the lower flange 19, 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 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, it can be pulled out smoothly 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, or 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.

Further, the upper surface of the cavity 36 is closed, but the lower surface is open so that a connecting member can be inserted thereinto.
An insertion hole 44 into which the end of the handle can be inserted is formed in the upper part of the cavity 36.

Furthermore, on the inner surface of the abutting surface of the external wall 35,
A guide rib 42 for guiding the connecting member is provided in a protruding manner. The guide rib 42 is inserted into the insertion holes 37 and 38.
and 39 in the longitudinal direction, and its lower end 4
5 is formed at a height such that the bottom plate of the connecting member does not come into contact with it when the connecting member rises and reaches the uppermost end, preferably with a distance of 1 to 2 mm between it and the bottom plate of the connecting member ( (See Figures 1 and 3).

Further, a small hole 40 into which the positioning projection of the connecting member fits is bored on the short side wall 8 side of the external wall 35.
A connecting member position confirmation hole 80 is bored below the small hole 40 (see FIG. 4).

The positioning protrusion of the connecting member fits into the small hole 40, and the connecting member is held in a predetermined position, and its height position is confirmed by the position confirmation hole 80.

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

As shown in FIGS. 5 to 9, the connecting member 50 has a plate-like or frame-like structure instead of a conventional rod-like structure in order to reduce weight.

More specifically, a recess 52 is formed by cutting the upper part of a rib 68 provided on the front surface of the slide plate 51, and a rack-shaped tooth 54 is provided in this recess 52 following an upwardly facing upper plate 53. Pawls 55, 56, and 57 are protruded from the rear surface at right angles.

Furthermore, a slit 68a is formed in the rib 68 to prevent deformation during molding.

The rack tooth 54 is provided only in the upper part of the recess 52, and a reinforcing plate 5 is provided on one side of the rack tooth 54.
8 are integrally formed. The claws 55, 56 have back plates 60, 61 connected in the same direction,
A horizontal reinforcing plate 6 is attached to the upper part of the back plates 60 and 61.
2 and 63 are provided, and slits 60a and 61a are formed to prevent deformation during molding. The back plates 60, 61 are guided in contact with the guide ribs 42.

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, since the bottom of the cavity 36 is open for insertion of the connecting member, it is important to prevent foreign matter from entering in order to smoothly raise and lower the connecting member.

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, 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 pawls 55, 56, and 57 are made into sloped surfaces, there is no looseness in the engagement state with the hook.
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
5 is configured such that when pushed down to the lowest position within the cavity 36, the protrusion 67 is fitted into a small hole 40 formed in the outer wall 35 of the column 4.

Further, below the positioning flexible piece 65, confirmation characters, marks 83, 84, etc., which constitute a position confirmation display section 81, are provided.

That is, a rectangular recess 82 is formed, and above the recess 82, characters 83 for confirming that the connecting member 50 has been lowered to the lowest end are displayed, for example, ``Release'' indicating a separated state. In addition, the recess 82
Below , characters 84 are displayed to confirm that the connecting member has risen to the uppermost position, for example, ``SET'' indicating the assembled state.

The confirmation characters and marks 83, 84, etc. are configured to appear in the connection member position confirmation hole 80 when the connection member is moved up and down and held at the uppermost or lowermost end (Fig. 10). and 11th
(see figure). The confirmation characters, marks 83, 84, etc. that constitute the position confirmation display section 81 can be displayed by any method such as labeling, printing, engraving, etc.

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 connected to the cavity 36 of the column 4.
A pinion-shaped tooth 75 is provided at the end portion of the connecting member 50 to engage with the rack-shaped tooth 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, by rotating the handle 70 and rotating the grip part upward, the pinion-shaped teeth 75 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 and the meshing state between the two is released, the external wall 35
The projection 67 of the flexible positioning piece 65 of the connecting member 50 that has been pushed down while pressing the inner surface of the connecting member 50 is fitted into the small hole 40 . By fitting the projection 67 into the small hole 40, the connecting member is held without inadvertently moving up and down. At the same time, the upper position confirmation display section 83 is displayed within the position confirmation hole 80.

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, the longitudinal side wall 5,
That is, by abutting the abutting surfaces 43 and rotating the grip portion of the handle 70 outward, the hooks are sequentially inserted into the hook insertion holes from below, and moreover, by the rotation of the handle 70, the upper portions of the bottle boxes are brought into contact with each other. Because of the pressure, the two bottle boxes can be joined more tightly.

As the handle 70 rotates, the pinion-shaped tooth 75 at the tip of the handle 70 and the rack-shaped tooth 54 at the upper part of the connecting member 50 mesh with each other, and the connecting member 50 gradually moves as the back plates 60, 61 are guided by the guide ribs. When the handle 70 is raised and the handle 70 is horizontal, the connecting member is pulled up to its uppermost position.

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, the two bottle boxes H are completely connected, and the lower position confirmation display part 84 appears in the position confirmation hole 80 (Figs. (See Figure 13).

In this way, if characters or marks are provided as the position confirmation hole and position confirmation display part of the connecting member, the position of the connecting member can be easily confirmed, so two bottle boxes can be reliably connected and separated. This allows safe transportation work and prevents damage to the connecting hooks.

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, it is possible to reduce the weight of the connecting member, prevent deformation during molding, and moreover, the guide ribs make it possible to smoothly It is possible to go up and down.

Further, since the height position of the connecting member is confirmed by the connection position confirmation hole and the confirmation display section, reliable and safe connection is possible.

Furthermore, the bottom plate of the connecting member has a similar shape to the gap,
Since it is sized to almost close the gap, the intrusion of foreign matter is prevented and the connecting member can be moved up and down more smoothly.
