Description

The The invention relates to a packaging with a wall, z. B. a canister, bottle, tube, box, box, separate or molded closures, Lid and other accessories for such containers and the same. The invention particularly relates to a Blown bottle made of glass or preferably of plastic of any kind.

The The invention particularly, but not exclusively, relates to packaging materials of the type mentioned from a resilient plastic material as container for cleaning and care products. In such applications is by the consumer often he asked for a container to exert a squeezing force by hand must to the container contents put under pressure, allowing a metered delivery of the container contents made through a pouring opening can be. It can basically every spot of the container because of the sense of touch of the consumer because of the uniform surface finish the container no guidance for can provide a preferable job. Similar conditions exist when handling the containers, to move them from one storage place to another. there can the containers slip easily out of hand, especially if on the surface slippery deposits of the contents of the container have sold. Analogous conditions exist in closures, z. B. screw or Aufsteckkappen with which the pouring of containers can be closed. Furthermore, there is a need for individualizing visual Design possibility of Packaging means, without thereby their economical production is questioned.

Besides that is it often useful, if you have the spatial Location or orientation of the packaging means only by the Tatsinn alone can determine. This possibility is for example in containers for shampoo or shower room beneficial if the user because of the foam closed his eyes in his face and still notice want where the opening or the closure of the container is arranged and whether the container upright or in reverse Location is in his hand.

Of the Invention is therefore the object of a packaging to provide means of the type mentioned, the sense of touch of the To appeal to the user, so that the user in particular the spatial location / orientation of the Bottle can feel blind, without affecting the geometry of the packaging means to pay attention.

These Task is inventively characterized solved, that at least one localized area of the outer surface of the Wall has a plastic material with a hardness that varies to the hardness a plastic material on the rest Part of the outer surface of the Wall is.

The Invention busy especially with the so-called haptic, the doctrine of the sense of touch. According to the invention surface of packaging material in partial areas, also continuously on the Circumference, provided with a different plastic material, which is in the haptic and preferably also in the color of the remaining part the surface of the packaging means.

To the particularly simple and comfortable feeling of spatial location and orientation of the packaging means it is advantageous if the locally limited Area provided only in the lower or only in the upper part of the wall is.

If in a further advantageous embodiment of the invention in the lower Part of the wall at least one area with a lower hardness and is provided in particular with a rubber-like feel, places this close to the user, the packaging means in its lower Area to grab.

Farther It is suggested that the outer surface of the locally bounded area with the remaining part of the outer surface of the Wall substantially aligned. This embodiment offers advantages in terms of aesthetics and also the handling.

According to the current state of the art, blown bodies can only be produced with a uniform material surface. Only bubbles in the coextrusion process strip-like other, similar to the packaging material constructed material inclusions are possible. In the blown process, however, non-planar areas made of other materials, such. B. of thermoplastic elastomers (TPE) with a rubbery feel, which are also applied to complete peripheral areas realize. Therefore, it is proposed in a further particularly important embodiment of the invention that the locally limited area is part of a separate plastic part, which is connected to the remaining part of the wall. The main body of the packaging means, in particular the bottle body, is thus at least two parts. The body consists of the actual packaging material (the bottle), which later receives the product and a particular injection-molded additional part, which forms the second part of the outer surface of the packaging means. This additional part, which here also "separate plastic Part "is called, in particular firmly connected by clamping, screwing, gluing, welding or the like with the remaining part of the packaging means.

The injection-molded separate plastic part can be made differently be. It can consist of the material that gives the different surface feel. It But it is also possible that the separate plastic part is a two-component plastic molded part, manufactured by two-component injection molding is. This coextruded Part has an inner core material, which for secure connection with the rest Part of the packaging means is used, and an outer layer of the material with the desired Haptics. In this case, the core material partially in the outer layer protrude or with the surface the outer layer essentially aligned, so flush be or out of the outer layer protrude so that the core material protrudes slightly above the surface, next to the changed one Haptic to produce more optical effects.

Farther It is suggested that the harder Plastic material is a polyolefin and the softer plastic material an elastomeric material. It is preferred if the harder plastic material PE, so polyethylene, or PP, so polypropylene, and the softer Plastic material is a thermoplastic elastomer.

Farther it is beneficial if the local area is different than the rest Part of the outer surface of the Wall colored is. A different color can also be within the separate, two-component Plastic part be provided with advantage, namely, if the Core material and the outer layer colored differently are.

Farther The separate plastic part can not only by the material and possibly the color, but also by the geometric Design of the surface from the rest Part of the outer surface of the Distinguish wall. It is suggested that the at least a locally limited area arranged a variety of distributed having knob-like structures on the outer surface. The knob-like structures can be easily felt by the fingers of a consumer, so that he can find without looking the place of the wall, at the one Force should be preferred. The knob-like structures can about that Be designed to be slip-resistant. At the same time they exert an optical appeal to the consumer, especially if they are by an appropriate Coloring or structuring, z. B. roughness, clearly from the background area take off. They are therefore suitable to visually inspect the packaging to individualize and to promote the purchase decision.

proposed will continue that the knob-like structures over the remaining part the outer surface of the Project wall by a small amount.

From It is also an advantage when the knob-like structures have a greater hardness than that of the plastic material the rest Part of the outer surface of the Wall have. However, it is particularly preferred if the knob-like Structures a lower hardness as that of the plastic material of the remainder of the outer surface of the wall to have.

In a special advantageous embodiment is also proposed that the wall is multi-shelled with an inner shell area the plastic material with the greater hardness and an outer shell area is formed, wherein the knob-like structures of the inner shell portion outward stand out and embedded in the plastic material of the outer shell portion circumferentially are. The packaging means according to the invention can be economically easy to mass produce according to the two-component injection molding process.

Provided the knob-like structures a lower hardness than that of the plastic material the rest Part of the outer surface of the Wall can continue to be provided with advantage that the knob-like structures in openings sit in the wall.

Although the invention below with reference to concrete embodiments It will be understood that the invention is not limited thereto limited is, but always can be used to advantage if a packaging of any kind with regard to their sense of touch and possibly also improves their visual appearance shall be.

First, the first embodiment will be explained in detail, which in the 1 to 7 is shown.

The plastic bottle is intended as a container for a liquid shower product. The bottle consists essentially of three parts, the blown bottle body 5 which has an upper opening 6 ( 7 ), but otherwise closed. The bottle also consists of a separate plastic part 7 and a closure 8th which is constructed in a manner known per se and on the opening 6 of the bottle body 5 pressed on and connected by snapping it. Preferably, the three parts, the bottle body 5 , the separate plastic part 7 and the closure 8th a different color.

The closure 8th consists of the plastic polypropylene (PP). He has in a conventional manner a closure lid 9 up, about a movie hinge 13 or other hinge constructions is hinged and with the help of a recessed grip 14 can be opened.

The opposite to the blue closure 8th white colored bottle body 5 consists of the plastic polypropylene (PP). On the underside of the bottle body 5 is the yellow colored separate plastic part 7 put on and locked, as particularly clear 7 evident. The separate plastic part 7 is injection molded in a two-component process. The outer layer consists of the plastic TPE (thermoplastic elastomer), the inner layer, ie the core layer, consists of the plastic polypropylene (PP). The outside of the separate plastic part 7 wears a knobbed structure 4 in the form of individual pips extending slightly over the surface outwardly. On the outside of the bottom of the separate plastic part 7 ( 5 ) no pimples are provided. At four areas 15 the core layer of the plastic part extends 7 through the outer layer. This core layer is significantly harder than the outer layer, and the areas 15 serve as sliding aids for the container during transport in the filling plants. Similar elements can also on the outside of this plastic part 7 be attached as a design elements that may also have technical advantages. The bottom of the separate plastic part 7 ( 5 ) has any number of differently shaped openings, preferably two circular openings 19 ,

The connection of the separate plastic part 7 with the bottle body 5 becomes particularly evident in 7 , Four inside the plastic part 7 and longitudinally extending plastic tracks 16 engage in corresponding undercuts of the bottle body 5 one. The separate plastic part 7 will after completely pushing on the bottle body 5 of locking elements 18 of the bottle body 5 held, which with corresponding locking elements on the rails 16 of the plastic part 7 correspond.

The following will be on 8th Reference is made, showing a container according to the invention according to a second embodiment, the general reference numeral 1 wearing. From the container 1 are only the peripheral wall 2 and bottom wall 3 to see. The upper end of the container, not shown 1 can be configured in any way. For example, it may be provided with a pouring opening or the like closable by a closing cap. The peripheral wall 2 may have a cylindrical, rectangular, oval or other desired configuration.

At the peripheral wall 2 of the container 1 is near the bottom wall 3 a variety of knob-like structures 4 provided, their distribution over the peripheral wall 2 can be regular or interrupted. If desired, therefore, areas of the peripheral wall 2 without nubby structures 4 be provided. It is preferred that the knob-like structures 4 at diametrically opposite locations of the peripheral wall 2 are provided, so that from opposite points of the peripheral wall 2 from by means of the thumb and finger of a hand a squeezing force on the container 1 can be exercised, the knob-like structures 4 give an indication to the user at which point the squeezing force should preferably be exercised. Although the knob-like structures 4 in the present embodiment of the invention at a portion of the peripheral wall 2 near the bottom wall 3 the container are provided, instead of or in addition, other areas of the peripheral wall 2 to be selected. The knob-like structures 4 can with the surface of the peripheral wall 2 aligned or protrude above the surface by a small amount. They may have a round, square, oval, or other suitable cross-sectional configuration and may be flat, arched, smooth, or rough on the exposed surface.

The knob-like structures 4 exist in contrast to the previous embodiment of a plastic material having a hardness other than the hardness of the outer surface of the peripheral wall 2 forming plastic material. Depending on the choice of plastic material for the knob-like structures 4 Consequently, these can have a greater or lesser hardness than that of the surface of the peripheral wall 2 have plastic molding material.

Of the container is preferably produced after two-component injection molding, as is the expert in principle is known, wherein a component of the plastic material with the greater hardness and the other component is the plastic material with the lower one Hardness includes. A preferred plastic material of the former type is a Material from the group of polyolefins, in particular polyethylene (PE) or polypropylene (PP). A preferred plastic material the latter type is a material from the group of rubber-elastic Materials such as elastomers, especially thermoplastic elastomers.

When two-component injection molding a container with the knob-like structures 4 if this has a greater hardness than that of the plastic material on the outer surface of the peripheral wall 2 should have, preferably the procedure is such that in a first step, an inner shell of the container peripheral wall 2 from the harder plastic material together with the knob-like structures projecting outwardly therefrom 4 is injected. On the existing inner shell then becomes an outer surface of the peripheral wall 2 forming outer shell of the softer plastic material injected, whereby the knob-like structures 4 be embedded in the softer plastic material of the outer shell.

If it is desired that the knob-like structures 4 a lower hardness than that of the plastic material on the outer surface of the peripheral wall 2 should have, it is proceeded so that in a first step, the complete peripheral wall 2 is injected from the harder plastic material, wherein at the same time one of the plurality of knob-like structures 4 corresponding plurality of perforations in the peripheral wall 2 be provided. In a subsequent step, the softer plastic material becomes the perforations of the peripheral wall 2 sprayed to the knob-like structures 4 to accomplish. These can be on the inside of the peripheral wall 2 be connected by thin connecting webs like a net.

The wall thickness of the container perimeter wall 2 Can be over the entire length of the container 1 be substantially uniform. However, it can also be provided that the wall thickness at one of the knob-like structures 4 containing portion of the peripheral wall 2 larger than the remaining sections of the container 1 is, causing the container 1 near z. B. the bottom wall 3 a higher dimensional stability would be obtained than in the other areas. A reverse wall thickness distribution could be advantageous for some applications.

2 shows a Aufsteckkappe according to another embodiment of the invention, the general reference numeral 10 wearing. In this embodiment, the knob-like structures 4 in the peripheral wall 2 the slip-on cap 10 on diametrically opposite broadsides 12 intended. They thereby give the user an indication of where a finger should be applied to the broadsides 12 to deform. Such a deformation of the broadsides 12 is z. B. required to Rastmontagemittel 11 the slip-on cap 10 to bring out of engagement with complementary engaging means on a container (not shown), if desired, the Aufsteckkappe 10 Remove from the container to spend its contents. In an analogous manner, the peripheral wall of a screw cap could be designed to improve their handling. The knob-like structures could also be provided on an outer cap which includes an inner closure cap to facilitate removal of the outer cap.

Finally, can it desired be, the invention in additional equipment for packaging means of the aforementioned Art. For example, could the wall of a container or a cap mountable, z. B. clampable panel, Plaque, plate or the like (not shown) in the aforementioned manner be formed and provided with knob-like structures. Of the The term "ancillary equipment" further excludes a peripheral wall of a container or bandage comprising a closure cap (also not shown) one.
