Definitions
- the present invention relates to a preform and a container with reinforcing elements.
- the present invention relates to the field of providing protrusions and/or grooves in a preform and a container.
- the process of producing for example bottles for beverages includes injection- molding of a preform and blow-molding of the container is known in prior art.
- a major task within this field is to decrease the weight of the final container thereby maintaining the same filling volume.
- These light-weighting containers however come to their limits when the mechanical performance of the empty or filled container is negatively influenced, which makes the handling of the container in the production line and later during storage and transport more difficult or even impossible.
- the containers can deform or even get broken due to the external load, if the containers are not designed to withstand the external forces.
- a further problem with light- weighting containers arises when the container is filled with fluids under pressure, e. g. with carbonated beverages. In this case the container still has to provide enough strength to withstand the internal pressure.
- Thin and light-weighted containers which are blow-molded from a thin preform further pose problems during the production of the preform itself.
- the material is injected into the mold from the end cap, so that the material flows along the full preform length before forming the neck part.
- this requires a minimum wall thickness of the preform to allow the material to flow through the mold to fill the neck part.

- Figure 24 is a flow chart showing the process steps for producing a preform according to the present invention.
- Figure 25 is a flow chart showing the process steps for producing a container according to the present invention.
- the present invention generally relates to a plastic preform for a container comprising at least one protrusion and/or groove.
- the present invention relates to a preform comprising at least one reinforcing element.
- the reinforcing elements have an elongate or longish shape and are extending in any linear direction of the preform.
- the preform according to the present invention has variable wall thicknesses thereby providing a structure with elongate strengthening elements.
- the preform according to the present invention comprises elongate or linear protrusions and/or recesses.
- the preform according to the present invention has a substantially constant wall thickness and has one or more ribs extending inside and/or outside the preform.
- the ribs, grooves or the reinforcing elements on the outside wall can extend in a vertical, horizontal, diagonal or any other direction or into different directions being a combination of the before-mentioned possibilities.
- the ribs, grooves or reinforcing elements on the outside wall extend in a vertical direction.
- the problems with thin walled preforms during the injection-molding can be solved.
- a preform with thinner wall can be produced industrially as the material during the injection-molding can easily flow through the ribs to fill the neck part.
- the amount of material to produce a good looking slim container from the preform with sufficient mechanical properties is significantly decreased.
- containers can be produced being light-weighted and having thinner walls, but at the same time having an improved strength with respect to top-load and/or internal pressure.
- the container thereby has several improvements compared to prior art containers. Usually, when using a standard preform without ribs during the blow-molding reinforcement, ribs are added in the blow-mold to provide a container with improved strength. Such added ribs however result in an interrupted exterior surface of the container, which is not desirable from an aesthetic point of view. Further, with this method only outside ribs can be provided.
- the container according to the present invention is preferably a bottle, into which different kinds of fluids can be filled.
- fluids are beverages, e.g. water, juices or carbonated beverages.
- Figure 1A shows a vertical cross-section of a first embodiment of a preform 1 according to the present invention.
- a preform 1 comprises a neck portion 2 or thread portion, an intermediate portion 3 and a body portion 4.
- the neck portion 2 can comprise one or more protruding parts 5 which allow to attach the cap to the final container. The neck portion 2 during the blow-molding process remains unchanged.
- the preform 1 comprises side wall 6 extending from the neck portion 2 to the body portion 4 and forming the bottom 7 of the preform 1.
- the preform 1 according to the first embodiment comprises several ribs 10 extending in a vertical direction from a middle part 9 of the intermediate portion 3 to the bottom 7.
- the ribs 10 do not begin right below the neck portion 2, but their end is spaced apart from the neck portion 2 and begins within the intermediate portion 3. They are extending along at least a part of the length of the side wall 6 and join each other at the central point of the bottom 7.
- the preform in this embodiment can have a step 8, i.e. an increase in thickness of the side wall 6 along the vertical direction, so that the side wall 6 near the neck portion 2 is thinner than the side wall 6 near the body portion 4.
- the present invention also comprises preforms without steps having a substantially constant thickness of the side wall 6.
- preforms without steps having a substantially constant thickness of the side wall 6.
- ribs the term "ribs" is used, the present invention is not limited to ribs but can encompass any other type of elongate protrusion.
- the elongate protrusions serve as reinforcing elements.
- Figure IB shows a cross-section of the preform 1 as shown in Figure 1A along the line indicated by arrows A.
- the preform 1 along a horizontal circumferential line comprises a substantially constant thickness d of the side wall 6 and only at several points comprises inner ribs 10 protruding from the inside surface 6a of the side wall 6.
- the ribs have a substantially triangular cross-section.
- the triangular inner ribs 10 thus provide a selective thickening of the side wall 6 of the preform 1.
- the thickness of the sidewall 6 at the portions with no ribs can be made thinner than compared to standard preforms.
- standard preforms usually have a wall thickness of at least 2,2 mm.
- Figure 2A shows a vertical cross-section of the preform 1
- Figure 2B shows a horizontal cross-section of the preform 1 as shown in Figure 2A along the line indicated by arrows A.
- the different parts of the preform are identical to the preform according to the first embodiment as shown in Figure 1. However, is the length of the ribs is increased with respect to the preform as shown in Figure 1, so that the ribs extend along the complete sidewall from the neck portion 2 to the bottom 7 As can be seen in Figure 2B the wall 6 again comprises a substantially constant thickness d and a plurality of ribs 10 are protruding from the inside surface 6a of the side wall 6. The outer surface 6b of the side wall has no ribs.
- the ribs as shown in Figures IB and 2B have an equal distance between each other but it is also possible to provide ribs having different distances to each other.
- the number of ribs can be one, two or even more for example up to several hundred ribs depending on the type of final container.
- Figures 3 A and 3B again show a vertical cross-section and a horizontal cross- section through a third embodiment of a preform 1 according to the present invention.
- this preform there is not provided a substantially constant thickness of the side wall 6, but a rather constantly varying thickness of the side wall 6 is provided.
- the thickness of the side wall 6 along the vertical direction is always constant but varying along the horizontal direction of the side wall.
- grooves or recesses 20 having a minimum wall thickness dO of the side wall 6.

- the side wall 6 of the preform will result into a corresponding side wall 31 of the container.
- the side wall 31 also has an inner side 31a and an outer side 31b.
- the inner rib 12 of the preform will result in corresponding inner ribs 32 or protrusions or reinforcing elements in the final container.
- the transition from the inner rib 12 of the preform into the protrusion 32 of the final container is schematically indicated in Figure 11 with an arrow B.
- the surface of the final container will have a substantially continuous, i.e. a smooth shape.
- the surface of the container has no interruptions deriving from reinforcing or ornamental elements attached to the preform after producing the preform or attached to the container after blow-molding the container.
- This is schematically shown by the shape of the inner side 31a of the final container from which it can be seen that there is in fact a thickened portion which results from the inner rib 12, but it is smoothly integrated into the side wall 31 of the final container.
- FIG. 12 The same configuration for the case of outer ribs 13 is shown in Figure 12. Again a cross-section of a preform with four outer ribs 13 is shown. A part 30 of the final container is indicated by dashed lines. As can be seen the side wall 31 comprises an inner wall 31a being flat and an outer wall 31 having a smoothed rib or protrusion 33 resulting from the outer rib 13 of the preform. Thereby, the final container is strengthened,.

- Figure 19 shows a cross-section of a preform having outer horizontal ribs 15 according to the present invention. Also shown in Figure 19 is a part 30 of a final container blow-molded from such a preform 1.
- the final container in this case comprises a side wall 31 having a substantially flat outer side 31b and an inner side 31a having smoothed outer ribs 34.
- ribs which are already provided within the preform instead of attaching ribs during the blow-molding process to the container, a very smooth and substantially continuous inner surface can be achieved.
- the possibility of providing inner ribs 34 on the final container further is only possible when providing a preform with inner ribs 14.
- a preform and a corresponding container further has the advantage, that no protrusions will be present on the outer side, so that labeling applications are simplified. Labeling is improved since less problems with wrinkles or witness lines occur. This also makes the appearance of the final container more aesthetic.
- FIGS 20A and 20B different possibilities of positioning ribs according to the present invention are shown.
- a preform 1 is shown and the neck portion 2 is also schematically indicated.
