Description

[Detailed description of the invention] (Industrial application field) This invention relates to a synthetic resin bottle box with a partition wall, and in particular, the bottle box is split into half the size, and two of the bottle boxes are placed side by side. This invention relates to a synthetic resin bottle box on which conventional size bottle boxes before division can be stably stacked.

(Prior art) Synthetic resin bottle boxes conventionally used for storing and transporting bottles for beer, soft drinks, etc. are designed with vertical and horizontal lattice-like partition walls installed between the side walls to separate and store the bottles. Between 20 and 30 bottles can be stored in the chamber formed by the tile.

However, when a large number of bottles are stored in one box, it is heavy and inconvenient to carry.

Therefore, in recent years, we have tried to downsize the conventional bottle box by dividing it in half and stacking two of these bottle boxes next to each other and then stacking the bottle boxes of the size before split molding. A bottle box configured to allow for transportation and storage has been proposed. For example, a bottle box having such a structure is shown in German Patent Application No. 3034650.

(Problems in the Prior Art) The conventional bottle box as described above is divided into halves in size as follows.

FIG. 6 is a plan view showing a conventional bottle box before division.

Reference numeral 1 denotes an upper flange provided at the upper end of the four circumferential side walls. Inside, a compartment 3 for bottle storage is formed by a lattice-shaped partition wall 2, and a lattice-shaped bottom rib 4 is attached to the bottom frame at the lower end of the side wall. Together with 6, it forms the bottom 5.
The lower surface of the bottom part 5 protrudes below the lower flange 7 at the lower end of the side wall, and is structured to fit into the opening of the upper bottle box when stacked, allowing stable stacking.

This example shows a bottle box containing 20 bottles, but in order to make it smaller, the bottle box is divided into two parts in the longitudinal direction from the partition wall located at 1/2 of the length l in the transverse direction. It is molded.

Figure 7 shows the divided molded bottle boxes lined up and the size before the divided molding (i.e. the original size 2
This is a cross-sectional view of stacked bottle boxes (double the size).
In this way, when the bottle box is divided and molded to be half the size, a side wall is naturally formed on the dividing surface. However, when two bottles with this structure are placed side by side and a conventional size bottle before split molding is stacked on top of it, the bottom of the conventional bottle is placed on the top of the side wall, making it unstable. Cannot be stacked.

In addition, if the size is such that they can be stacked on top of each other as shown in Figure 7, upper and lower flanges are formed for reinforcement, so if the compartments are the same size, the overall width is only the width of the new flanges. The size of the compartment becomes larger, and the dimensions of the compartment become smaller accordingly.In order to make the dimensions of the compartment the same as before, the side walls must be shifted outwards.

However, if the side walls are shifted outward, the following problems arise. That is, FIG. 8 is a partial cross-sectional view showing the structure of the lower end of the side wall and the bottom, but when the side wall 8 is shifted outward as shown by the imaginary line in order to increase the size of the compartment, the bottom frame 6 itself Since the bottle cannot be moved outward due to stacking with a conventional bottle box, the bottle is placed on the connecting part 9 that connects the lower end of the side wall 8 and the bottom part 5, so that the bottle can be stored stably. The problem was that I couldn't do it.

(Purpose of the invention and means for solving problems) This invention was made in view of the above points,
The purpose is to create bottle boxes that are split into half the size, so that two of these bottle boxes can be placed side by side, and a conventional bottle box that has not been split can also be stacked stably. To provide a synthetic resin bottle box which can stably store bottles and has a robust bottom structure.

In order to achieve the above object, this invention has the following configuration.

That is, the bottom is formed by a lattice-shaped bottom rib parallel to the side wall and a bottom frame at the lower end of the side wall, and a compartment is formed inside by a lattice-shaped partition wall, and the bottom rib and the bottom frame are arranged at the lower end of the side wall. For bottle boxes that protrude below the lower flange of the bottle, the normal size bottle box is divided into two parts, the outer dimension of the short upper frame is approximately half that of the normal bottle case, and the outer dimension of the longer upper frame is The upper surface of one side is formed in a wave shape with convex portions and recessed portions alternately, and the recessed portion is formed on an extension line of the bottom rib perpendicular to the longitudinal side wall in a plane, and has a depth dimension y from the upper surface of the short side upper frame, and a lower portion. When the protruding height of the bottom from the flange is z, y≧z, and furthermore, the bottom rib of the bottom and the top surface of the bottom frame are approximately the same plane, and the lower end of at least one longitudinal side wall and the bottom frame are partition walls. It is characterized in that it is connected by a connecting cross section that is approximately doglegged in cross section and is provided at the lower end.

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

FIG. 3 is a plan view, FIG. 4 is a rear view cut in the left half, and FIG. 5 is a front view.

The bottle box H is formed into a rectangular shape in a plane, and the lower parts of the support sections 11, 12, 13, and 14 at the four corners are connected by the longitudinal side walls 15, 16 and the short side walls 17, 18, and the upper end is connected by the longitudinal upper frame 20, 21, short upper frame 22,
23, and the portion surrounded by the pillars, side walls, and upper frame is a window 24.

Further, a handle 30 is rotatably supported on the upper frames 22 and 23, and the upper frames 22 and 23 are configured in a substantially U-shape so as to fit into the outer surfaces of the upper frames 21, 22 and 23 when laid down horizontally. . The bottom part 25 of the bottle box H is formed by a bottom frame 28 and lattice-like ribs 40 provided inside the bottom frame 28 in parallel with the side walls. Thus, a compartment 27 is formed for storing the bottles in isolation. The outer dimensions of the short upper frames 22 and 23 are approximately half that of a conventional bottle box (original size bottle box) before split molding, and the bottle box H shown in this embodiment is This is a bottle box containing 10 bottles in total, 2 bottles and 5 bottles in the longitudinal direction.

The upper surface of the longitudinal upper frame 20 is formed in a wave shape, the upper surface of the wavy convex part 20a is slightly lower than the upper surface of the short upper frame 22, 23, and the wavy recessed part 20b is formed in the longitudinal side wall 20, 21 in a plane. It is located on the extension line of the bottom rib 40 orthogonal to the bottom rib 40, and is located below the bottom rib of the upper bottle box when two of these bottle boxes H are stacked side by side and conventional bottle boxes of twice the size are stacked. too,
The convex portion 20 is formed at a depth that does not contact the bottom rib.
a and the recess 20b are continuous by an inclined surface 20c.

That is, the depth dimension from the upper surface of the short upper frames 22, 23 to the upper surface of the longitudinal upper frame 20, that is, the depth dimension of the wavy convex part 20a is x, the depth dimension of the concave part 20b is y,
Furthermore, the lower flange 2 of the bottom part 25 and the bottom frame 28
When the height dimension from 9 is z, x<z≦y
and preferably x<(1/2 to 3/4)z.

With this structure, bottle boxes H with the same shape
In the case of so-called stick stacking, the bottom frame 2 of the bottom part 25
8 is locked by the protrusion 20a. Furthermore, by butting these bottle boxes together, a conventional bottle box of twice the size can be stacked on top of it, and in this case as well, the bottom rib and bottom frame of the upper bottle box are placed in the recess 20b. Therefore, the lower flange 29 can be placed on the upper surface of the upper frame of the lower bottle box and stacked safely (see FIG. 7).

Furthermore, even when taking out the upper bottle box, since the unevenness is continuous due to the sloped surface, the bottom of the upper bottle box can be lifted slightly, without getting caught, and it can be removed in a direction parallel to the side wall where the unevenness is formed. It can also be easily pulled out.

FIG. 1 is a partially enlarged plan view of a bottle box according to this invention, and FIG. 2 is a sectional view taken along the line A--A in FIG.

At the lower end of the longitudinal side wall 15, a gap 45 and a connecting bar 46, which are the features of this invention, are provided on the inner surface of the lower end of the longitudinal side wall 15, and the upper surface of the bottom frame 28a and the upper surface of the bottom rib 40a are substantially on the same plane.

The lower end of the longitudinal side wall 15 and the bottom frame 28 are connected by a connecting bar 46
connected by. The connecting bar 46 has a substantially doglegged cross section with its upper surface protruding into the bottle box, and is formed integrally with the lower end of the partition wall 26, with its tip preferably having a length so as not to come into contact with the stored bottle B.

The inner surface of the lower end of the longitudinal side wall 15 is connected to the bottom frame 2 as described above.
8, and a connecting bar 46 is formed integrally with the lower end of the partition wall, so that the gap 45
The portion has a structure similar to a recess formed by cutting out the connecting bar 46.

Therefore, even if the side walls are moved outward to increase the size of the compartment, bottles can be stored stably, and the connecting bars prevent the bottom from expanding outward, and the strength is maintained sufficiently. .

In the above embodiment, the gap 45 on the inner surface of the lower end of the side wall and the connecting bar 46 are provided only on one longitudinal side wall 15 side, but they can be provided on the other longitudinal side wall 16 side as well, if necessary.

(Effects of the invention) As described above, according to the synthetic resin bottle box of this invention, unevenness is formed on one side of the upper longitudinal frame, and a gap is provided between the inner surface of the lower end of the side wall and the bottom frame. Since the bottom frame and the bottom frame are connected by connecting bars that are long enough not to touch the bottles, it is possible to not only make the bottle storage area sufficiently large, but also to arrange two bottle boxes side by side. The bottle boxes can be stacked on top of each other with bottles twice the size before being divided, and even when the same bottle boxes are piled up in a so-called stack, they can be stacked stably without slipping.

In addition, the bottom part is half the size before being divided by the connecting bars, and even if two bottles are placed side by side, they are the same size as a conventional bottle box. Can be stacked.

Furthermore, since the connecting bars are long enough not to touch the bottle, the bottle can be stored stably, and the bottom structure can be made more robust by the connecting bars.
