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. This invention relates to a synthetic resin bottle box that can be stacked on top of conventional bottle boxes.

(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 upper part of the connecting member are engaged 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 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 in the Prior Art) Conventionally, the following problems have occurred in the case of connectable bottle boxes that are split into half sizes.

In other words, if you try to stack a conventional size bottle box before split molding on top of two connected bottle boxes, the bottom rib and bottom frame of the upper bottle box will touch the upper edge of the abutting surfaces of the connected bottle boxes. Because they do not fit into the opening, stable stacking is not possible.

In addition, contrary to the above case, if two connected bottle boxes are stacked on top of a conventional bottle box, the upper frame of the lower bottle box will fit between the bottom frames of the butted part, and There is a problem that the bottle box cannot be pulled out.

FIG. 16 is a partially cross-sectional explanatory view showing a bottle box of a conventional size before being split and molded, and a bottle box that has been split and molded connected, and one of the bottles is stacked on top of the other.

A connectable bottle box H is connected and stacked on top of a bottle box C that is twice the size of the conventional bottle box, and when these are pulled out from a high place, the bottom frame of the bottle box H can fit into the upper opening. Since it protrudes beyond the lower flange, the upper frame W of the lower bottle box fits between the bottom frames when it is pulled out halfway and cannot be pulled out any further. If you want to pull it out further, you have to lift the upper bottle box while pulling it out. Similar inconveniences occur when stacking and unloading, because when the shelves are high, some of the stacks are left on top and slide.

In addition, in order to prevent the upper frame of the lower bottle box from fitting between the bottom frames of the bottle boxes connected as described above,
Although the problem shown in FIG. 16 can be solved by making the bottom frame on the abutting surface side bulge outward, it becomes impossible to stack identical bottle boxes on top of each other. That is, as shown in Fig. 17, if a bulge b is formed on the abutting surface side of the bottom frame, which forms a recess when connected, and is flush with the lower flange, it will be difficult to The bottom frame on the end side is placed on the upper frame of the lower bottle box, making it impossible to stack them.

(Purpose of the invention) This invention was made in view of the above points,
The purpose is to create connectable bottle boxes that are split and molded into half the size, and these two bottle boxes can be connected and stacked on top of a conventional size bottle box that has not been split and molded. Moreover, it is an object of the present invention to provide a synthetic resin bottle box that can be stacked and unloaded smoothly, and also enables the bottle boxes that can be connected to be stacked together in a so-called stick stack.

(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 engages with the upper part of the connecting member is pivotally supported on the upper frame, so that when two bottle boxes of the same shape are butted against each other, one side In a bottle box in which two bottle boxes can be removably connected by inserting the other hook into the hook insertion hole of the bottle box and engaging this hook with a connecting member, the top surface of the upper frame on the butting surface side is It 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, and the depth from the upper surface of the short side upper frame is y, and the depth of the bottom part from the lower flange is y. When the protrusion height is z, y≧z,
Furthermore, an adjustment rib is provided on the lower surface of the lower flange on the abutting surface side that bulges outward from the bottom frame, and the bottom frame on the lower end of the opposite side wall is recessed inward between the bottom ribs to provide a clearance for the convex portion. It is characterized by the fact that it has been formed.

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

Figure 1 is a plan view, Figure 2 is a bottom view, Figure 3 is a front view, Figure 4 is a back view with the right half sectioned, Figure 5 is a right side view, Figure 6 is Figure 1A- It is a longitudinal cross-sectional view taken along the A line.

The bottle box H connects the four corner pillars 1, 2, 3, and 4 below with longitudinal side walls 5, 6, and short side walls 7, 8, and furthermore, the upper end is connected with longitudinal upper frames 10, 11, short upper frames 12,
13, and the portion surrounded by the pillars, side walls, and upper frame is a window 14.

Furthermore, a handle 60 is rotatably supported on the outer surfaces of the upper frames 11 and 12. Bottle box H
The bottom part 15 is formed by a lattice-shaped bottom rib 16 provided parallel to the side wall and a bottom frame 17 around the four peripheries, and a lattice-shaped partition wall 18 is provided inside to separate and store the bottles. A chamber 19 is formed. The outer dimensions of the upper longitudinal frames 10 and 11 are approximately half that of a conventional bottle box before split molding, and the bottle box H shown in this embodiment has a total of two bottles in the transverse direction and five in the longitudinal direction. It is a bottle box containing 10 bottles.

Next, the longitudinal upper frame 10 will be explained.

The upper surface of the longitudinal upper frame 10 is formed into a wave shape.

That is, the depth from the upper surface of the short upper frames 12 and 13 to the upper surface of the longitudinal upper frame 10, that is, the depth of the wavy convex part 20 is x, the depth of the concave part 21 is y, and furthermore, the bottom part 1
5 and the protruding height of the bottom frame 17 from the lower flange 23 is z, x<z≦y, preferably x<(1/2 to 3/4)z.

Therefore, the upper surface of the wavy convex portion 20 is lower than the upper surface of other upper frames, for example, the short upper frames 12 and 13 by x, and the wavy recess 21 is perpendicular to the long side walls 5 and 6 in a plane. It is formed in a size such that the bottom rib 16 fits on the extension line of the bottom rib 16. Therefore, when a conventional bottle box of the size before division is stacked on top of two connected bottle boxes H, the bottom rib of the upper bottle box will fit. The convex portion 20 and the concave portion 21 are continuous by an inclined surface 22.

With this structure, conventional bottle boxes that are twice the size can be stacked on top of the connected bottle boxes, and in this case, the bottom rib and bottom frame of the upper bottle box are placed in the recess 21. On the other hand, the convex part 2
0 is inserted between the bottom ribs, the lower flange 23 can be placed on the upper surface of the upper frame of the lower bottle box, and the bottles can be stacked safely.

Furthermore, even when the upper bottle box is taken out, since the unevenness is continuous by the inclined surface, it can be easily pulled out in a direction parallel to the side wall on which the unevenness is formed.

Note that although the convex portion 20 is formed to be lower than the upper surfaces of the short upper frames 12 and 13 by x, the upper surface of the convex portion 20 may be on the same plane as the shorter upper frames 12 and 13, that is, x=0.

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 abutting surface of the support column 1 is recessed by a dimension l from the abutting surface 24 of the longitudinal side wall 5, and L-shaped hooks 30, 31 and 32 are provided to protrude outward in the plane. The protruding dimension of the hooks 30, 31, and 32 is 1 of the concave dimension l of the abutting surface of the support column 1.
~2 times, preferably approximately twice, i.e. 2 l.

On the other hand, the column 4 has a double wall structure that forms a triangular gap 28 between the inner wall 26 and the outer wall 27, and the abutting surface of the outer wall 27 is the same size l as the concave size of the column 1. It protrudes from the surface 24. Therefore, the abutting surface 24 of the side wall 5
Based on this, the external wall 27 and the hooks 30, 31, and 32 protruding from the support 1 are on the same plane.

Furthermore, hook insertion holes 33, 34, and 35 into which the hooks 30, 31, and 32 can be inserted when connected are formed in the abutting surface of the external wall 27. Further, a small hole 29 into which the positioning projection of the connecting member fits is bored on the short side wall 8 side of the outer wall 27.

The upper surface of the cavity 28 is closed, but the lower surface is open so that a connecting member can be inserted, and the cavity 28 is closed.
An insertion hole 36 into which one end of the handle can be inserted is formed in the upper part of the handle.

Next, the bottom shape of the bottle box H will be explained.

7 and 8 are cross-sectional views showing the bottom structure taken along lines B--B and C--C in FIG. 1.

An adjustment rib 40 protruding from the bottom frame 17 is provided on the lower surface of the lower flange 23 on the longitudinal side wall 5 side, located directly below the recess 21 on the longitudinal upper frame 10. As is clear from FIG. 2, the adjustment rib 40 is provided in a certain area adjacent to the bottom rib 16, and its outer surface is approximately flush with the outer surface of the lower flange 23, and its lower surface is approximately flush with the lower surfaces of the bottom rib 16 and the bottom frame 17, respectively. It is said that

Therefore, the lower surface of the lower flange 23 has the adjusting rib 4
0, there is a recess 4 that extends inward to the bottom frame 17.
1.

Note that the shape of the adjustment rib 40 is not limited to the embodiment. 2 when connected and stacked
It can be formed into any shape as long as the bottom surface of each bottle box is continuous in part or in its entirety and does not fit into the upper frame of the lower bottle box. Therefore, the adjustment rib 40
may be formed on the entire lower surface of the lower flange on the abutting surface side or only partially, and can be freely formed in any direction, and furthermore, it has a shape that extends and bulges the bottom frame 17 to the end surface of the lower flange 23. Good too.

Further, relief portions 42 are formed in the bottom frame 17 on the opposite longitudinal side wall 11 side by recessing inward at regular intervals between the bottom ribs 16 (see FIGS. 2 and 8). The relief part 42 is formed in the bottom frame at the lower end of the partition wall 18, so that when stacked, the bottom frame 17 is connected to the longitudinal upper frame 1.
It is formed as an allowance for the portion to be placed on the convex portion 20 of 0.

FIG. 9 is a perspective view of a handle attached to the outer surface of the upper frame of the bottle box H.

A pin 62 is inserted into a mounting hole 61 of the handle 60, and the handle 60 is rotatably supported by the short upper frames 12 and 13, and a pinion-shaped tooth 63 that engages with a connecting member to be described later is provided at the right end. This pinion-shaped tooth 63 is inserted into the gap 28 of the support column 4 through an insertion hole 36 formed on the side surface of the short upper frame 13, and is configured to mesh with the connecting member.

Next, the connecting member inserted into the gap 28 will be explained.

FIG. 10 is a perspective view of the connecting member, FIG. 11 is a front view, and FIG. 12 is a plan view.

The connecting member 50 is cut into the upper part of the slide plate 51 to form a recess 52, and above the recess 52, a lock-shaped tooth 53 is provided. Slide plate 51
At the rear end, claws 55, 56, and 57 are protruded at regular intervals according to the number of hooks, and when the connecting member is pulled up, they are inserted inside the hooks 30, 31, and 32 to engage them. The locking state is released when the connecting member is pulled down. The claws 55 and 56 have a back plate 7.
0 and 71 are consecutively arranged in the same direction, and the pawl 57
A substantially triangular bottom plate 72 having substantially the same shape as the gap 28 of the support column 4 is integrally provided at the lower end of the support column 4 .

Reference numeral 74 denotes a flexible piece for positioning the connecting member 50. The flexible piece 74 for positioning is separated on three sides by notches 75, and has a protrusion 76 formed on the outer surface of its lower end. When the positioning flexible piece 74 is pushed down to the lowest position within the cavity 28, the protrusion 76 is configured to fit into the small hole 29 of the external wall 27.

Next, a case will be described in which the bottle boxes H according to the above configuration are connected.

First, the handle 60 is rotated to lift the grip part upward, the meshing state between the rack-shaped teeth 53 of the connecting member 50 and the pinion-shaped teeth 63 of the handle is released, the connecting member 50 is lowered, and the hook insertion hole 3 is lowered.
3, 34, and 35 are completely opened. Connecting member 5
0 is pushed down, the protrusion 67 of the flexible positioning piece 65 fits into the small hole 29, and the connecting member 50 is held without inadvertently moving up and down. Next, the abutting surfaces 24 are abutted, and the hook insertion hole 33,
Hooks 30, 31 and 32 are inserted into holes 34 and 35, respectively. If the handle 60 is rotated in this state, the pinion-shaped teeth 63 of the handle 60 and the rack-shaped teeth 53 of the connecting member 50 will mesh with each other, so the connecting member 50 will be pulled up, and the pawls 55, 56, 57 will engage the hook 30, 31 and 32, and the two bottle boxes H are completely connected (13th
(see figure).

Further, it is possible to smoothly load and unload or stack two bottle boxes H connected to a conventional bottle box. That is, since the adjustment rib 40 is provided on the lower surface of the lower flange on the abutting surface side to partially protrude the bottom, the bottom surfaces of the two bottle boxes are continuous as the same surface, and as shown in FIG. Unlike the conventional case shown in the figure, the upper frame of the lower bottle box does not fit between the bottom frames.

Next, a case will be described in which the bottle boxes H are stacked together in a so-called stack.

FIG. 14 is a partially cross-sectional explanatory view of the bottle boxes H stacked up, and FIG. 15 is a partially enlarged view.

The front and back surfaces of the upper and lower bottle boxes H are reversed, respectively, and the upper bottle boxes H are stacked alternately so that the abutting surfaces are on the back side of the lower bottle boxes H. In this way, the adjustment rib 40 of the upper bottle box H is aligned with the lower bottle box H.
are stacked in contact with the inner surface of the longitudinal upper frame 11, and are stacked with deviations by the bulge dimension of the adjustment ribs 40.

However, the upper frame 10 and the bottom frame 17 at the lower end of the longitudinal side wall 6 overlap each other.
0 and the concave portion 21, and on the other hand, the part of the bottom frame 17 that is placed on the convex portion 20 is formed with an inwardly recessed relief portion 42. The part 20 will be inserted.

Therefore, even if the bottom frame 17 overlaps the longitudinal upper frame 10, the bottom frame 17 fits into the upper opening of the lower bottle box, and the bottle boxes H are stacked horizontally, and the relief part 42 By fitting the convex portion 20, stable stacking is possible without slipping. Furthermore, advantageously, the abutting surface side on which the hooks are protruded is placed inside the upper and lower bottle boxes, so that it is possible to prevent impacts to the hooks from outside during transportation or storage.

(Effects of the invention) As described above, according to the synthetic resin bottle box of this invention, the unevenness of the upper frame on the abutting surface allows two of these bottle boxes to be connected to form a bottle of the conventional size before split molding. It can be stacked stably with the box, and the bottom of the butt side has bulging adjustment ribs, so
It can be quickly stacked on or unloaded onto conventional bottle boxes.

In addition, together with the unevenness of the upper frame on the abutting surface side, the relief part of the bottom frame at the lower end of the opposite side wall makes it possible to stack the bottle boxes H together.
