Description

The invention relates to a plastic bottle crate according to the preamble of patent claim 1.

In bottle crates, which are predominantly injection-molded in one piece from plastic, the most varied of embodiments are known, but all of them have in common that at least one handle, primarily in one of the side walls, is provided which facilitates the handling of the crate, in particular its transportation. The predominant handle design is that a through opening is provided in a side wall near the upper edge of the box, which delimits a spar-like handle body between itself and the upper box edge. To grasp the box, one grips the hand from above over the upper edge of the box and reaches through the handle opening with the fingers so that the hand encloses the spar-like upper box edge and thus the box can be lifted and transported. For crates that are filled with full bottles, especially the 20-way crates that are mainly used, this causes difficulties due to the weight. The ideal shape of a handle as a fully solid handle cannot reasonably be realized for reasons of the necessary material savings in boxes molded from plastic. In addition, certain cycle times are specified in the manufacture of bottle crates which do not allow a handle to be fully shaped as a full profile on the bottle crate, especially since such a handle would also experience cooling difficulties. A fully trained handle would also lead to a corresponding weight gain and thus run counter to the efforts to make the bottle crate as light as possible.

Another disadvantage of the conventional bottle crate for the carrying behavior is that the upper crates of the crate are mostly profiled for reasons of stabilizing the side walls and also the grip areas of the crates, so that when the crates are gripped, one grips the profile edges of the profiles by hand, which press into the hand with the appropriate weight of the boxes.

The object of the invention is to provide a bottle crate which, with sufficient stability, ensures a material-saving grip design compared to a full profile, which enables bottle crates to be carried comfortably.

This object is achieved by the features contained in the characterizing part of claim 1.

According to the invention, the grip areas of a handle are divided into a large number of closely disputed lamellae, whereby one comes close to the ideal shape of a full profile with a closed grip surface, but nevertheless achieves a material-saving effect and a sensible production technology implementation Handles reached taking into account the cooling cycles of plastic injection molded boxes. The lamellae, which are preferably designed with round edges, provide a quasi-closed grip surface, which makes it easier to carry even heavy bottle crates. Furthermore, the lamella formations in the area of the grip areas, which are endangered for reasons of stability, lead to an increase in stability, which has an overall positive effect on the rigidity of the bottle crates. Compared to a conventional handle of a bottle crate with a U-shaped handle bar, a handle with slats only increases the weight by about 10 to a maximum of 30%, which is extremely cheap compared to the full profile and nevertheless guarantees the advantages of the full profile.

The lamellae can be raised in relation to the handle body, wherein they can be arranged on only one or more surfaces of the handle body and partially or over the entire circumference of the body. According to an alternative embodiment, the lamellae are formed in that corresponding recesses are formed next to one another in the handle body, two adjacent recesses between them delimiting the lamellae, which advantageously runs flush with the rest of the handle body, i. H. the generators of the slats merge flush into the box wall sections adjacent to the grip area.

To increase the grip area, it is preferred that the free lamellar edges are formed in the manner of knobs. However, the lamellar edges are rounded in a structurally simple manner.

According to an advantageous development of the invention, the slats are formed in a carrier element which can be retrofitted into a correspondingly profiled grip body, the protruding slats then forming the actual gripping surface of the bottle crate.

• 7 shows a part of a bottle crate for showing a handle body in a sectional view,
• Fig. 8 is a schematic plan view of a handle body with three alternative embodiments of lamella designs.

In the bottle crate shown in FIGS. 1 to 3, a handle 2, best seen in FIG. 2, is formed in the narrow side labeled 1, the T-shaped handle body 3 of which is delimited by two L-shaped through openings 4a and 4b. The handle body 3 is composed of a handle bar 5 on a vertical handle bar 6. The handle bar 6 is designed as a hollow profile, as best seen in the sectional view of FIG. 1.

1 and 2, the handle bar 5 is divided on its surface facing the inside of the box and at the top of the box into individual lamellae 7, which are closely spaced and arranged parallel to one another. These lamellae 7 are formed by corresponding cutouts 8 in the handle body or in the handle bar 5, each lamella 7 being delimited by two cutouts 8. Thus, in the embodiment according to FIGS. 1 to 3, the handle area of the handlebar 5 is that which is when the box is carried is gripped by hand on the handle bar 5, broken down into individual, closely spaced lamellae 7. If necessary, the vertical handle bar 6 can be divided into slats.

The shape of the slats 7 or the recesses 8 is best shown in FIG. 3. Thereafter, the handle body 3 is formed in the region of the handle bar 5 from an L-shaped web 9, from the inside 10 of which the slats 7 towards the inside of the box protrude at right angles. 3 runs flush with the upper end 12 of the web 9 and the inner edge 13 of the web 7 runs essentially parallel to the web 9 and flush with the end 14 of the web 9 Gripping the box with the hand coming edge 15 of the slats 7 is rounded. The ends 12 and 14, into which the lamella edges merge, are also preferably rounded. In the embodiment of FIGS. 1 to 3, the slats 7 are regular, that is. H. Equal to each other and have the same narrow distance from each other, so that a quasi-closed, that is to say a largely adapted to a closed grip surface is formed, which allows a comfortable gripping of the bottle crate.

In addition to the T-shaped handle 2 in the narrow side 1 of the box, a further, formed by a passage opening 16 handle is formed in the longitudinal side wall of the box, the upper handle bar 17 can also be formed with lamellae 18, but only schematically without further details are shown in Fig. 3. 3 leaves however recognize that the slats 18 are of different lengths and thus adapted to the grip surface of the hand.

The embodiment according to FIGS. 4 to 6 differs only slightly from the embodiment according to FIGS. 1 to 3, as far as the formation of the L-web 9 and the slats 7 are concerned. In particular, the L-leg 19 of the web 9 is angled upward at its front end, but here again the inner edge 13 of the lamella 7 runs flush with the rounded front end 14 of the web 9. Fig. 5 shows that in the area of the transition between handle bar 5 and vertical handle bar 6, the slats 7 are formed with increasing length.

Fig. 7 shows the upper part of a box edge, which forms a U-shaped handle body 3, which is delimited below by a recess 19 in the side wall of the box. Slats 7 extend at a short distance from one another within the profile of the handle body 3, a slat 7 being visible on the basis of the sectional illustration in FIG. 7. The lamella 7 is convexly curved outwards in the region of the grip surface at 20.

FIG. 8 shows only schematically different designs of lamella edges, the lamellae 7 being expanded like a mushroom at 21 at the upper end in accordance with the illustration on the left. The lamellae shown in the middle are round at their free lamella edges at 22, whereas the lamellae shown on the right are lump-shaped at 23 at their ends. Because of the lateral widening of the free lamella edges 21 and 23, these embodiments are characterized by a grip surface that is largely approximated to the closed grip surface. Of course, further deviations of the slat shape and the slat arrangement are possible. In particular, the slats can be aligned horizontally and / or vertically and / or diagonally, intersect and. Like ..
