Abstract

Plastic crate for transporting bottles has designs, e.g. letters, on its walls (1). These are produced by forming apertures filled with mesh (7) which are then filled with a different plastic, or differently colored plastic, to form raised characters. An independent claim is included for a method for making the crate in which the outer walls are molded in a first stage and the raised letters produce din a second stage using a different mold.

Description

The The invention relates to a plastic transport box in particular for the Transport of bottles, consisting of a bottom and four side walls and a method for its production.

such transport boxes are in great variety known. The bottler and beverage manufacturers put big ones It is important that your company name as well as your company logo and possibly more information big and clearly on the outside of the box are visible. That's why you have the outside for decades the boxes printed with these details by screen printing. This imprint was at longtime Use of the boxes unsightly in the harsh operation of bottle washing and bottling plants because the ink rubbed off. A few years ago, it was over to, instead of the post-box printing in the injection mold of Insert printed transparencies at the back, and print on them no longer rubbed off, because the printing on the box outer wall but protected by the foil.

A even more impressive advertising on the outside of a transport box are raised signs, letters and decorative elements on the side walls of a Box made of a different colored plastic than the side wall. The production of such raised signs on box walls, in spite of Years of harsh handling of boxes in operation not unsightly been, was previously not possible or only with a very large effort.

The Invention avoids the disadvantages of the prior art. It is the object of the invention, with a relatively low effort sublime Fonts and other characters and representations of a different color Plastic on sidewalls of plastic boxes made safe and clean, too with different depth, to install.

The Invention is that in at least one side wall in places a grid is formed, that of another and / or differently colored Plastic is interspersed, the sublime on the eye side, so letters, numbers or other additional information protruding from the wall or decorative elements forms.

This the ornamental or additional elements such as letters, numbers, pictorial Representations and other sign-forming plastic may be on its outer surface as well worn out and rubbed off, by its sublimity becomes the Only slight material removal is barely visible.

at Such a plastic transport box, it is favorable that the side wall on the inside in the area of the grid the gate marks the other or differently colored plastic. There are she for the viewer of the box invisible.

Around also the gate marks and flow channels too From the inside of the box to keep invisible, it is in this transport box made of plastic advantageous if the side wall with that of a other or differently colored plastic enforced by lattice a second inner sidewall is deposited which the gate marks and flow channels hidden.

there It is beneficial if the inner sidewall is different or differently colored plastic is sprayed.

The inventive method for producing a plastic transport box by injection molding, in particular for the transport of bottles is suitable and from a soil and four side walls is characterized by the fact that first injected a blank that's out of the final Floor and four inner sidewalls is that then in a second injection process at least one outer side wall with a different or different colored plastic after replacement of external parts the molding tool or after reacting the molded molding first is injected into a two tes mold, which next to the outer side wall also forms the lattice located in this, and that then after Exchange of external parts the mold against those on the outside of the outer side wall Form additional or ornamental elements, or after implementing the now a double sidewall sprues in a weiters Mold on the outer side wall Additional or ornamental elements sprayed in a third injection process become.

There In this process, everyone following the first injection molding more injection already can then be done when a stability of the molded part has just been reached, the production is done quite quickly and safely.

there it is convenient when the for the formation of additional or decorative elements needed plastic through channels in the between the outer and the inner wall cross-shaped molding tools is supplied.

there the supply of material can be achieved by means of the molding tools which engage between the outer and the inner wall carried out, which serve the formation of hollow columns.

It is practically the case that a shape tool is used, the forming of the outer side of the inner wall serving, used in the first injection mold plates are exchangeable against the molding of the outer side of the outer wall used in the second injection molding plates, while for the third injection molding only parts of the outer wall used in the second injection mold plates are interchangeable ,

The Essence of the invention is shown below on a in the drawing embodiment explained in more detail. It demonstrate:

1 a side view of a transport box before attaching the additional or decorative elements

2 a side view of a transport box after attaching the additional or decorative elements

The side wall 1 The transport box has different ribs 2 and 3 in the upper area, the handle opening 4 enclose. Also in the lower area, the side wall 1 of the transport box ribs 5 on. In the middle area between the ribs 2 and 5 Additional and decorative elements 6 , in this case raised lettering out of the side wall letter "EFEF" to install in a separate injection process, has the side wall 1 at the place of attachment of these additional and decorative elements 6 one grid each 7 on, which is flowed through by the plastic forming the raised additional and decorative elements and is usually enclosed. These grids 7 anchor the additional and ornamental elements 6 in the sidewall 1 ,

Claims (8)

Plastic transport box. in particular for the transport of bottles, consisting of a bottom and four side walls. characterized in that in at least one side wall in places a grid is formed, which is interspersed by another and / or differently colored plastic, which forms on the outside raised letters, numerals, as well as additional or ornamental elements. Plastic transport box according to claim 1, characterized characterized in that the side wall is on the inside in the area the grid gates the other or differently colored plastic. Plastic transport box according to claim 1, characterized characterized in that the side wall with that of another or differently colored plastic interspersed grid by a second inner Sidewall is deposited, which obscures the gate marks. Plastic transport box according to claim 1, characterized characterized in that the inner side wall of another or differently colored plastic is sprayed. Method for producing a transport box made of plastic by injection molding, in particular for the transport of bottles is suitable and from a soil and four side walls consists, characterized, that first a blank that is sprayed out of the final Floor and four inner side walls, that then in a second injection process at least one outer side wall with a different or different colored plastic after replacement of external parts the molding tool or after reacting the molded molding first is injected into a second mold, which next to the outer side wall also forms the lattice in this one, and that then after replacement of external parts the mold against those on the outside of the outer side wall Additional or ornamental elements form, or after converting the now from a double sidewall existing injection molding in a further mold on the outer side wall additional or decorative elements are sprayed in a third injection process.
