Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a pallet container having a pallet, an outer casing, and an inner plastic storage tank which is introduced into the outer casing and supported on the pallet.

The term "pallet container" as used herein means a container unit having the above-mentioned structure and capable of being lifted and processed by the fork list vehicle or the like by the pallet. The pallet has appropriate clearance for the arms of the forklift vehicle to enter. The internal storage tank is basically blow-molded with a thermoplastic resin, and is mainly used for receiving, storing and transporting chemicals.

[0003]

In a conventional pallet container having a pallet, an outer casing and an internal plastic reservoir,
Each component is manufactured separately and then the outer casing is integrally joined to the receiving and shipping pallet.

The known pallet container (US Pat. No. 5,100,000), which is the starting point of the present invention, has a casing in the form of a round bar grid secured to the pallet by locking tongues which engage behind the round bar extending around the bottom edge. Is bound to. This feature simplifies the connection of the outer casing to the pallet, but its disassembly is cumbersome as it is not easy to unbend the locking tongue.

[0005]

SUMMARY OF THE INVENTION It is therefore an object of the present invention to develop a pallet container of the above construction which facilitates the connection of the outer casing to the pallet and the disassembly of the outer casing and the pallet. .

[0006]

However, the above-mentioned object is
The pallet is formed with a peripheral groove for receiving the outer casing, the introduction of which into the peripheral groove is made possible by the bottom edge of the pallet, which is ensured by the retaining tongue in the peripheral groove. The locking projection of the pallet is locked in the locking recess formed near the inner end of the tongue to secure the position of the tongue in the pocket. It has been found by the present inventors that this can be achieved by a pallet container

In the preferred embodiment of the invention, the recesses or pores in the pallet are elastically formed. In order to reliably and easily disengage the locking described above, the recesses or holes are connected to pockets formed in the pallet for receiving the tongue towards the center of the pallet.

Within the scope of the present invention, the pallet, the outer casing, and the inner storage tank can have any desired shape in their plane, for example, a circular contour, but the pallet surface has a square or rectangular shape with rounded corners. Preferably, the tongue and / or pocket are
Placed along the edge. According to the invention for fixing the tongue, according to the invention, a locking recess is formed near the inner end of the tongue and a pallet locking projection is engaged therewith to bring the tongue into place in the pocket. Place in place. This is the storage material in the internal storage tank,
For example, when chemicals are filled, locking is performed,
This is accomplished by allowing this to be released from the locked condition when the reservoir is empty. For this reason, in the present invention, the pallet is elastically deformable at least around the locking projections, and when this zone is not elastically deformed, the recesses or pores do not engage with it and chemicals or the like are stored in the internal storage tank. When the storage material is stored, the zone is pressed down by the weight of the material and elastically deforms, so that the concave portion of the tongue and the projection of the pallet can be engaged.

In the present invention, the pallet can be made of various kinds of materials, but it is preferable that the pallet is made by blow molding a plastic, especially a recycled thermoplastic resin. In the process of connecting the outer casing to the pallet, the pallet is composed of upper and lower deep-drawing sleeves each having a hollow pallet leg at the bottom and a circumferential groove at the top of the pallet. Part,
This can be easily achieved by forming a pocket by combining the two. Both of these sleeves are joined by thermoplastic fusion or other means into a pallet and by inserting the arms of the forklift vehicle into the gap between the legs,
It can be easily received, lifted and transported, and it can be placed anywhere by dropping it.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail below with reference to the accompanying drawings which exemplarily show embodiments of the present invention.

The illustrated pallet container has a pallet 1, an outer casing 2 and an inner plastic storage tank 3 as its basic structure. The outer casing 2 is detachably connected to the pallet 1 near the bottom edge 6 thereof. The inner tank 3 is introduced into the outer casing 2 and supported on the pallet 1. FIG. 1 only schematically shows that the inner tank 3 can have an outlet 4. Although not shown, this inner tank generally has a lid, and the outer casing 2 extends to this top lid.

As can be seen by comparing FIGS. 2 and 3, on the pallet 1 there is provided a peripheral groove 5 for receiving an outer casing 2, which casing 2 is surrounded by its bottom edge 6. It is engaged with the groove.

The bottom edge 6 of the outer casing 2 is fixed to the circumferential groove 5 by a holding tongue 7. This tongue extends through the recessed hole 8 in the wall of the circumferential groove 5. These pores 8 extend over the bottom edge 6 of the casing 2.
In this embodiment, the tongues extend through the apertures of the lattice structure of the casing 2 and over the lattice rod 9 around the bottom. As can be seen from FIG. 3, the peripheral groove 5 is provided in the pallet obtained by plastic molding. Following the circumferential groove 5, a pocket 10 adapted to receive the tongue 7 extends towards the center of the pallet.

In this embodiment, the pallet 1 has a rounded corner in its plane and the tongues 7 and / or pockets 10 are arranged along each perimeter of the contour of the pallet 1.

As can be seen in FIG. 3, the tongue 7 has a locking recess 11 formed near its inner end with which the locking projection 12 of the pallet engages. Due to the engagement of the projection 12 with the recess 11, the tongue 7 is placed in the corresponding pocket 10 in the illustrated manner. In the illustrated embodiment,
The recess 11 is formed as a void.

In FIG. 3, the pallet container according to the present invention is shown with the internal plastic storage tank 3 in an empty state. As a matter of course, the pallet 1 is elastically deformable in the peripheral region of the locking projection 12, so that the projection 12 can be engaged with the recess 11. The arrow 14 indicates the direction in which the weight of the storage material acts on the bottom 15 of the internal plastic storage tank 3.
The weight 5 hangs down due to this weight and contacts the surface of the pallet 1. When the internal storage tank 3 is filled, the engaging projection 12 further hangs due to the elastic deformation of the projection peripheral zone 13 due to the weight of the storage material, and as a result, the engaging projection 12 is reliable in response to any stress, vibration, etc. during transportation. Bring to a standstill.

A special feature of a pallet container having a pallet 1, an outer casing 2 and an inner plastic reservoir 3 which is introduced into the outer casing 2 and mounted on the pallet 1 is that the outer casing 2 at its bottom edge 6 is
The holding tongue 7 is fitted into the circumferential groove 5 formed in the pallet.
This fitting state is ensured by means of the recesses or holes 11 formed near the end of the tongue and the projection 12 of the pallet 1.
By engaging with and, the tongues 7 in the illustrated mode in the pocket 10 of the pallet are positioned. The pallet 1 is elastically deformable in the peripheral zone of its engaging projection, and in this non-deformed state, the engaging projection 12 does not have to engage with the recessed portion or the hole 11 of the tongue 7 and the internal plastic reservoir. When 3 stores the storage material, its projections 12 reliably engage the recesses or pores due to the deformation of the elastic deformation zone 13 in the pallet 1 due to the weight of the storage material.
