Abstract
A pallet container comprising a pallet, an outer housing and a plastics inner tank. The outer housing is releasably connected near its bottom edge to the pallet. The inner tank is introduced into the outer housing supported on the pallet. The pallet is formed with a peripheral groove for receiving the outer housing, which engages in the groove by way of its bottom edge. The bottom edge of the outer housing is secured in the groove by retaining tongues which extend through edge-closed recesses in the groove, engage over components of the bottom edge of the outer housing and are releasably secured in the pallet.
Description
The invention relates to a pallet container comprising a pallet, an outer housing and a plastics inner tank, the outer housing being releasably connected near its bottom edge to the pallet, the inner tank being introduced into the outer housing and supported on the pallet. The term "pallet container" refers to a unit which has the construction described and which through the agency of the pallet can be picked and manipulated by a fork lift truck or the like. The pallet has a~propLiate entry channels for the arms of a fork lift truck. As a rule, the inner tank is a thermoplastics blow moulding and serves to receive, store and transport substances, more particularly chemical substances.
In conventional pallet constainers comprising a pallet, an outer housing and a plastics inner tank, these components are manufactured independently of one another then subsequently interconnected. In use, the outer housing is usually non-releasably connected to the pallet.
In the known pallet container which forms the starting point for the invention (US 5 100 000) the outer housing, which is in the form of a lattice of round steel rods, is positively connected to the pallet by means of detent tongues which engage behind a bottom peripherally extending round steel rod. These features simplify connection of the outer housing to the pallet but demounting is elaborate because it is not a simple matter to bend back the detent tongues.
Here disclosed is a pallet container of the construction described with a simpleconnection and disconnection arrangement between the outer housing and the pallet. This enables the pallet to be released from the outer housing in operation, for example, in order to reuse the pallet elsewhere. The outer housing can readily be drawn off the inner tank of the disconnection if this is required and if the inner tank has been designed applupliately in view of the weight of the filling material.
More particularly, in accordance with the invention, there is provided, a palletcontainer which comprises a pallet, an outer housing and a plastics inner container within the outer housing, said housing ~eing supported on said pallet; a peripheral groove formed in the pallet, a bottom edge to said housing received in said peripheral groove, retaining tongues received in pockets in said pallet and securing said bottom edge of said housing in said groove, detent recesses formed in said tongues adjacent their ends and, detent elements formed in said pallet engageable under load in the inner container into said recesses for securing said tongues in reference position in said pockets.
.,~ - 2 -In a preferred embodiment of the invention, the receiving groove in the pallet is contrived by resilient shaping. To ensure that the connection described is reliable in operation and can be released reliably in a very simple way, the groove merges towards the centre of the pallet into pockets with which the pallet is formed to receive the tongues.
In other embodiments of the invention the pallet, outer housing and inner tank can have in plan any required contour, for example, a round contour. Preferably, however, the pallet is in plan view a figure of square or rectangular contour with rounded edges and the tongues and/or pockets are disposed along the sides of the square or rectangle. To secure the tongues they are forrned near their ends with detent recesses in which detent elements of the pallet engage and locate the tongues in their reference position in the pocket. This can be so effected that the tongues are secure when the inner tank is full but that the securing can be released quite simply when the tank is empty. To this end, the pallet is resiliently deformable in the zone near the detent elements, the detent elements release the detent recesses in the tongues in the undistorted state of such zone of the pallet and when the inner tank is full the detent elements can be pressed into the detent recesses by the weight of the filling and with resilient deformation of the resiliently deformable zones of the pallet.
The pallet can be made of a wide variety of materials. Preferably, the pallet ismoulded from plastics, more particularly a recycling thermoplastics. If the pallet is combined from two deep-drawn plastics shells, the bottom of which has recessed pallet feet and the top of which has the recessed peripheral groove, and the pockets are in the form of complementary facing relieved formations in the top shell and in the bottom shell, the formations co-operate with one another to form the pockets. The two plastics shells can be joined together by thermoplastic welding or in some other way to form the pallet, the guide channels for the fork arms of a fork lift truck being disposed between the pallet feet.
Embodiments of the invention will now be described with reference to the accompanying drawings in which:
Fig. 1 is a partial and partly fragmented front elevation of a pallet container embodying the invention, Fig. 2 is an inverted plan view of the pallet of Fig. 1, and Fig. 3 is an enlarged view of the part A of Fig. 1.
The pallet container shown in the drawings comprises as its fundamental construction a pallet 1, an outer housing 2 and a plastics inner tank or container 3. Near its bottom edge the housing 2 is releasably connected to the pallet 1. The inner tank 3 is introduced into the outer housing 2 and supported on the pallet 1. It is shown merely schematically in Fig. 1 that the inner tank 3 can have an outlet 4. It also normally has a top closure having a lid and the outer housing 2 extends up to the height of the top closure of the inner tank 3 in a manner which is not shown.
As a comparison of Figs. 2 and 3 will show, the pallet 1 is formed with a peripheral groove 5 to receive the outer housing 2, the same eng;~ging by way of its bottom edge 6 in the groove 5.
The bottom edge 6 of the outer housing 2 is secured in the groove 5 by retainingtongues 7. The same extend through edge-closed recesses 8 in the walls of the groove 5. They extend over parts of the bottom edge 6 of the housing 2 and are releasably secured in the pallet 1. In the embodiment the tongues extend through an opening in the lattice construction of the housing 2 and over the bottom peripheral lattice rod 9. As can be gathered from Fig. 3, the groove S is contrived in the pallet by plastics shaping. Following on from the groove S
there can be seen, extending towards the centre of the pallet, pockets 10 adapted to receive the tongues 7.
In the embodiment, and preferably, the pallet 1 is in plan of a rectangular contoured figure with rounded corners. The tongues 7 and the pockets 10 are disposed along the sides of the figure.
As can be seen in Fig. 3, the tongues 7 are formed near their end with detent recesses 11 in which detent elements 12 of the pallet 1 engage. Engagement of the elements 12 in the recesses 11 locate the tongues 7 in their reference position in the associated pocket 10. In the embodiment the recess 11 in the tongues 7 can be just a bore.
Fig. 3 shows a pallet container embodying the invention in a state in which the inner tank 3 is empty. As will be al~pa~nl, the pallet 1 is resiliently deformable in the zone 13 of the detent elements 12. The design is such that in the undeformed state of the associated zone 13 the detent elements 12 expose the recesses 11 adequately in the retaining tongues. Arrows 14 show how the weight of the filling material acts on the base 15 of the inner tank 3. The base then sags further and settles on the top of the pallet 1; when the inner tank 3 is full the detent elements 12 become pressed into the recesses 11 by the weight of the filling material and with resilient deformation of the resiliently deformable zones 13 hereinbefore described.
The result is a reliable locking which copes with all transport stresses, vibrations or the like.
,. . .
Special significance attaches to a pallet container comprising a pallet 1, an outer housing 2 and a plastics inner tank 3 which has been introduced into the outer housing 2 and loaded on the pallet 1, which is formed with a peripheral groove 5 to receive the outer housing 2, introduced by way of its bottom edge 6 into the groove 5, the edge 6 being secured in the groove 5 by retaining tongues 7 formed near the tongue ends with detent recesses 11 in which detent elements 12 of the pallet 1 engage and determine the reference position of the tongues 7 in pockets 10. The pallet 10 is resiliently deformable in the region of the detent elements 12 and in the undistorted state of this region the detent elements 12 leave clear the recesses 11 in the tongues 7. When the inner tank 3 is full the detent elements 12 are pressed into the recesses 11 by the weight of the filling material and with resilient deformation of the resiliently deformable zones 13 of the pallet 1.
