Definitions
- the present invention relates to a plastic crate according to the preamble of claim 1.
- Such a crate is known from DE-A-38 23 650.
- the lower edge of the handles is formed by a thick hollow part with a round cross section.
- the cavity in this hollow part is an elongated straight channel.
- the known crate has the disadvantage that the shape of the handle is still not optimal in order to lie easily in the hand.
- the object of the invention is to provide a plastic crate with improved handles.
- the channel-shaped cavity is curved it is possible to provide the crate with a handle, which has also a hollow part at its upper edge, so that the handle lies very easily in the hand and also has the required strength, whereas it is still possible to mould the handle in a technically and economically advantageous manner.
- the crate shown in Fig. 1 comprises a bottom 1, two long vertical side walls 2 and 3, and two short vertical side walls 4 and 5.
- the side walls of the crate are made double-walled.
- the two long side walls 2 and 3 lying opposite each other are each provided at the top side with a handle 6, 7 respectively, which at the bottom side is bounded by a handle opening 8, 9 respectively.
- the handles 6 and 7 are integral with the rest of the crate and are made partially hollow.
- Fig. 2 the handle part with the handle 7 is shown on an enlarged scale, the hollow part being indicated by the reference numbers 11a and 11b.
- the cavity in the hollow part 11a, 11b is in the form of an elongated channel 12a, 12b which is surrounded by wall parts 13a, 13b together forming an essentially closed wall.
- the channel-shaped cavity 12a, 12b is U-shaped, and the wall parts 13a, 13b form, as it were, a U-shaped tube.
- the channel-shaped cavity 12a, 12b has an essentially round cross-section.
- the legs of the U run parallel to the bottom 1 of the crate, and the wall parts 13a and 13b of the U-shaped channel 12a, 12b form the top and bottom part of the handle 7.
- a handle formed in this way lies well in the hand, so that great carrying comfort is achieved.
- the wall parts 13a, 13b of the U-shaped channel 12 are connected to each other by a connecting wall part 14.
- this wall part 14 lies on the outside of the crate, with the result that the handle 7 on the outside of the crate is smooth.
- the handle 6 is designed in the same way as the handle 7.
- side walls 4 and 5 of the crate can also be provided with a handle, like the handles 6 and 7.
- the wall part 14' connecting the wall parts 13a, 13b can also be provided approximately in the longitudinal centre plane 15 of the handle.
- the advantage of this is that the stress distribution in the handle is better.
- the channel-shaped cavity 12a, 12b is the shape of a U.
- the channel-shaped cavity can, however, be other shapes, for example the shape of a Z or an S.
- a handle of a crate designed in the manner described above lies easily in the hand and can be formed in a technically and economically advantageous manner.
- a method for forming a handle according to the invention is described in Applicant's Netherlands patent application No. 9002483 entitled: "Method and device for forming a cavity in a plastic injection-moulded product”.
- the invention is described for a crate of a particular shape.
- the invention is not, however, limited to such a crate, and can equally well be used for crates or trays of a different shape and different dimensions, provided with a framework or not.

Description
- The present invention relates to a plastic crate according to the preamble of
claim 1. - Such a crate is known from DE-A-38 23 650. In a particular embodiment of this known crate the lower edge of the handles is formed by a thick hollow part with a round cross section. The cavity in this hollow part is an elongated straight channel.
- The known crate has the disadvantage that the shape of the handle is still not optimal in order to lie easily in the hand.
- The object of the invention is to provide a plastic crate with improved handles.
- This object is attained by a crate according to
claim 1. - Due to the fact that the channel-shaped cavity is curved it is possible to provide the crate with a handle, which has also a hollow part at its upper edge, so that the handle lies very easily in the hand and also has the required strength, whereas it is still possible to mould the handle in a technically and economically advantageous manner.
- Preferred embodiments of a crate according to the invention are claimed in the sub-claims.
- The invention is explained in greater detail in the example of an embodiment which follows with reference the drawing, in which:
- Fig. 1 is a view in perspective of a plastic crate according to the invention;
- Fig. 2 is a view in perspective and on an enlarged scale of a handle part of the crate of Fig. 1, viewed from the inside of the crate;
- Fig. 3 is a cross-section on a further enlarged scale of the handle of Fig. 2, along the line III-III in Fig. 2;
- Fig. 4 is a longitudinal section on the same scale as in Fig. 3 of the handle of Fig. 2, along the line IV-IV in Fig. 3; and
- Fig. 5 is a cross-section similar to Fig. 3 of a slightly modified embodiment of a handle of a crate according to the invention.
- The crate shown in Fig. 1 comprises a
bottom 1, two longvertical side walls vertical side walls long side walls handle - The
handles - In Fig. 2 the handle part with the
handle 7 is shown on an enlarged scale, the hollow part being indicated by thereference numbers - As indicated in Figs. 3 and 4, the cavity in the
hollow part elongated channel wall parts shaped cavity wall parts shaped cavity bottom 1 of the crate, and thewall parts channel handle 7. A handle formed in this way lies well in the hand, so that great carrying comfort is achieved. - The
wall parts channel 12 are connected to each other by a connectingwall part 14. In the embodiment of Figs. 3 and 4 thiswall part 14 lies on the outside of the crate, with the result that thehandle 7 on the outside of the crate is smooth. - The
handle 6 is designed in the same way as thehandle 7. - It is pointed out that the
side walls handles - As indicated in Fig. 5, in a modified embodiment of a handle according to the invention the wall part 14' connecting the
wall parts longitudinal centre plane 15 of the handle. The advantage of this is that the stress distribution in the handle is better. - In the embodiment shown the channel-
shaped cavity - A handle of a crate designed in the manner described above lies easily in the hand and can be formed in a technically and economically advantageous manner. A method for forming a handle according to the invention is described in Applicant's Netherlands patent application No. 9002483 entitled: "Method and device for forming a cavity in a plastic injection-moulded product".
- In the example of an embodiment the invention is described for a crate of a particular shape. The invention is not, however, limited to such a crate, and can equally well be used for crates or trays of a different shape and different dimensions, provided with a framework or not.
