Abstract

A crate 1 for bottles with cylindrical body portions has double-skinned corner portions 7 which define with portions 13 of an internal partitioning grid 5 corner compartments 6a for bottles. The inner skin 12 of the corner portion is formed with vertical ribs 14 adjacent the grid portions 13. These ribs, which are interconnected with the outer skin 8 of the corner portion to form hollow columns 14a therewith, strengthen the corner portions and allow the spacing of the skins thereof to be reduced so that the size of the compartment can be increased for given external crate dimensions, and as the ribs are located adjacent the partitioning portions 13 they occupy space which would otherwise be free and do not reduce the effective size of the corner compartments.

Description

[Detailed Description of the Invention] The present invention relates to a frame box (grade, box with partitions), more specifically,
The present invention relates to a generally rectangular crate having a base and sidewall means and an internal partition grid for accommodating items such as a plurality of pins or the like.

Such a frame box must be strong and capable of being stacked in a stable state.

To increase the strength of the structure, double walls are used on its side walls (
・It is known that this occurs especially at the corners. However, this has the disadvantage of reducing the effective internal cross-sectional area of the crate for a given external cross-sectional area. This disadvantage is especially true when it is undesirable to increase the external side dimensions of the crates, for example because multiple crates are required to be stacked on a pallet with a given dimension. This is a serious obstacle. It is an object of the present invention to minimize the effective cross-sectional area of the crates and to enable stacking of the crates as an alternative to stacking them vertically in columns. The goal is to provide frames that are used in The present invention relates to a generally rectangular crate used for a plurality of articles having a cylindrical main body, the crate having a base and side wall means, and comprising an internal partition grid, the side wall means comprises four double-walled corner portions, each of said corner portions for accommodating one of said articles with an adjacent mutually orthogonally extending portion of said partition grid connected to a respective corner portion; A frame box defining a division and consisting of an outer panel having mutually orthogonal parts and an inner panel spaced apart from the outer panel,
The inner plate of each of the corner portions has a respective grooved rib extending away from the outer plate and connecting each of the mutually orthogonally extending partition grid portions to the inner plate. The side wall means is formed to extend perpendicularly to the base, the side wall means comprising a spaced apart outer plate and an inner plate and having a double walled side wall portion extending between the corner portions. further portions of the grid extending perpendicularly toward the inner plate of the sidewalls, each of the at least longer sidewalls being adjacent to at least one of the further partition grid portions of the grid; The inner plate is formed with a groove-shaped rib extending away from the outer plate of the side wall portion and extending in a direction perpendicular to the base portion. , the sidewall means defining an upper rim of the crate having a substantially uniform thickness, the base comprising a plurality of downwardly extending structures with a plurality of structures between the structures; defining a groove in which rim portions of adjacent sidewalls of said sidewall means of two similar crates in which said crates are arranged in side-by-side stacking relationship are disposed; The groove-shaped ribs are arranged in the groove or adjacent to the groove, so that the two groove-shaped ribs arranged side by side are
Rims of adjacent sidewalls of similar crates, which are located in any one of said grooves, are at each end of said groove proximate to said groove-shaped rib or said groove. A frame box is provided that extends directly below the mold ribs.

Such channel ribs on both the corner portions and the side wall portions of the side wall means are adapted to form an abutment with the partition grid, the dimensions of the channel ribs being such that within the compartments of the crate, the channel ribs are is spaced apart from the cylindrical body of the article, and the spacing between the inner and outer panels of the portions not adjacent to the partition grid portion can be correspondingly reduced, thereby increasing the strength of the side wall portion. It will be understood that it is possible to strengthen the

Additionally, the crate may be provided with a groove in its base into which the rims of adjacent side walls of two similar crates arranged side by side in stacking relationship can be placed. Not only can the crates be vertically stacked one on top of the other to form a stable stack, but also the side wall means can be provided with grooved ribs so that the crates can be stacked as described above. when the rims of adjacent sidewalls of two similar crates placed in said groove are close to said grooved rib at each end of said groove or are in contact with said grooved rib. It will be appreciated that the grooves in each corner extend downward and help distribute the stack load through the layers of the stack, allowing the bottom layer of the box to better support the stack load. Preferably, the mold ribs are adapted to join the skin at the farthest ends of the ribs and are completely hollow at the corners.

In order that the invention may be better understood, one embodiment of the invention, given by way of example only, will be described below with reference to the accompanying drawings, in which: FIG.

In the drawings, there is shown a rectangular frame box 1 for use with a plurality of pins (not shown) having a cylindrical body portion.

The crate 1 has a base 2 and side wall means 3 formed of double plates extending upwardly from the base to an upper rim 4 surrounding the open upper end of the crate. An internal partition grid 5 is provided to form compartments 6 within the box, one compartment per pin. The side wall means 3, best seen in cross-section in FIG. It consists of an outer panel 8 having mutually perpendicular sections 9 and 10 and an inner panel 12 spaced from the outer panel 8.

Each corner section 7 together with adjacent mutually orthogonally extending sections 13 of the partition grid 5 forms a corner section 6a used for one pin, and the inner plate 12 has these partition grid sections 13.
A rib 14 extending away from the outer panel 8 and perpendicular to the base 2 is formed adjacent to each of the ribs 14 . The ribs rise from the base and extend slightly below the upper rim 4. The ribs 14 are combined with the skin 8 to form hollow columns 14a extending perpendicularly from the base 2. In the illustrated box frame, the ribs 14 at each corner are connected to the outer skin by means of a support member 24 at the outer end so that the corner is completely hollow. As can be seen from the circle 15 drawn in FIG. 1 to indicate the planar dimensions of the main body of the pin, by providing the lip 14 adjacent to the lattice section 13, the corner section can be reduced without reducing the effective area of the section. Strength can be increased.

This is because the ribs are located in locations within the compartment that cannot normally be utilized effectively. Due to the reinforcing effect of the ribs, it is possible to reduce the gap between the outer plate and the inner plate at the corner portion, and thus to increase the compartment area, without affecting the strength of the corner portion. To provide a more rigid structure and facilitate molding, the inner plate can be replaced with the outer plate and upper rim 4.
Although it is advantageous to keep the inner panels parallel to the outer panels in the central vertical plane of the corner sections, it is advantageous to separate them into compartments for a box with constant external dimensions. The distance between possible adjacent corners can be increased.

However, the only condition is that this length extends only in one direction, for example, along the long side of the crate, as shown in the illustrated crate, which is the central length extending through the short side of the crate. vertical plane,
That is, this can be achieved by making the inner plate parallel to the outer plate in the plane DD of the section 6a in FIG. As shown in the illustrated frame box, the strength of the corner portion is determined by curving the inner plate 12 facing the curved portion 11 of the outer plate with a radius larger than that of the curved portion 11 and over a wider area than the curved portion 11. This can be beneficially increased by increasing the space between the inner and outer plates.

It must be understood that doing so does not reduce the effective area of any corner section. The side wall means includes a double side wall extending between the corners 7, the long and short side walls being designated 16 and 17 respectively in the drawings. These side walls are respectively an outer panel 18 and an inner panel 1.
Consists of 9. The partition grid 5 includes a portion 20 extending towards a side wall, which in view of the above may be provided with ribs similar to the ribs 14 adjacent to one or more grid portions 20. It will be understood that it can be strengthened. In the illustrated embodiment, one such rib 21 is formed in the middle of each of the longer sidewalls 16. The openings 22 formed through the side wall means 3 form handles for the crate, and apart from these openings 22 and the recesses 23 formed above said openings, the frame formed by the skins 8 and 18 The outer casing of the box is smooth and continuous.

The inner plate 12 of the corner section 7 is also continuous, but is also connected to the outer plate 18 of the side wall by a support member 24 provided between the outer plate and the inner plate and reinforcing the structure of the side wall. A hole is bored in the inner plate 19 of the side wall portion. The inner plate of the longer side wall is formed between the top strip and the bottom strip of the longer side wall so that the longer side wall is a continuous double wall at the top and bottom. It is shown as having a rectangular hole 25 located in it. A hole 26, shown rising from the bottom of the inner plate and extending just below opening 22, is formed in the shorter side wall. By forming the holes 25 and 26, significant material savings can be made and the weight of the crate can be significantly reduced without weakening the side wall structure. The base 2 of the crate is also perforated and is shown as a lattice with a plurality of downwardly extending structures 27 shown arranged in three rows and four columns.

Adjacent rows and columns of the structure have corresponding grooves 28 between them.
(Fig. 3) and 29 (Fig. 2). Each groove has a uniform thickness as can be seen from FIG. It has a width such that it is located in the groove. The provision of this groove not only allows the crates to be vertically aligned and stacked on top of each other, but also stabilizes the stacked crates. As best seen from Figure 1,
The ribs 14 at the corners are adjacent to the side walls of the groove 28, and the outer walls of the groove 29 and the ribs 21 on the longer side walls are located in the middle of the intermediate groove 29.

Therefore, when superimposed as described above, groove 28 or 29
Adjacent upper rims of adjacent lower crates located therein are provided with ribs 14 or 2 at each end of said groove.
It extends to the vicinity of or directly below 1. In this way, the lowest one of the stacked boxes can better absorb the weight of all the boxes stacked above it. The illustrated crate is made of plastic material by injection molding, together with its sidewall means and the partition grid 5.
