Description

Multifunctional bottle

The present invention relates to a multi-functional bottle, characterized in that the content can be removed in two different output paths

Containers for liquid or viscous media such as food preparations, cosmetics, pharmaceuticals, disinfectants, lubricants and construction chemicals are known in many embodiments.

The containers have a dispensing opening adapted to their content. Most of these are openings in the neck of the container, which are closed by caps, screw caps or valves (normal discharge opening).

Already hundreds of years ago, the discharge openings in amphorae were sealed with wax. Over time, the closure methods have been refined, for. B. were compressible materials such. As cork, pressed into the discharge openings to protect the container safe from leaking. Many of the closures used earlier were no longer completely sealed after the first opening. With the onset of machining it was possible to produce threads for closure purposes in sufficient quantities, so screw caps were soon standard, as they guarantee a safe reclosure even after the first opening. In the era of plastics processing, closures that have been bounced or stuck on are added to the conventional screw cap, as they are easier to manufacture and machine. By way of example, those cited by the company Menshen (D - Finnentrop), which produce and distribute a comprehensive range of closures with dispensing opening and for dispensing openings and sell - z. B. Hinge Bounces, Flip Top Caps, Turret Push On Cap, Turret Screw Cap. Due to the high production precision and the durable materials, it is possible to produce and use very inexpensive and sealed closures.

Most of the known containers are also filled by the later discharge opening. In order to achieve a fast filling, the openings must therefore have a certain size. It must also be ensured that a pressure equalization can take place during the filling, in some cases containers have a further opening for this purpose. For controlled removal, the opening used for filling is usually too large, so that it has long been common practice to limit the width of the openings through apertures or valves. Valves also have the advantage that they allow the passage of media only in one direction and open only at a certain, if usually only at a low, overpressure, s

Another variant of the output is the active removal of the contents by means of a pump. Thus, for many media special pumps are available which are usually operated by hand or just a finger and allow a targeted application. For low-viscosity media, there are corresponding pumps that have a nozzle plate in their discharge opening, which allows a targeted spraying The spray pumps are usually screwed or bounced as a closure in the container neck. For example, DE 196 18 71 1 may be mentioned here, which describes a commercial atomizer pump.

A property of liquid or viscous media which substantially affects the dispensing method is their behavior under shear stress. Thus, it is possible to produce media which have a gel-like, non-fluid character at rest, but whose viscosity is reduced under shear stress such that they become flowable and even finely sprayable.

German patent application 103 43 851 describes gel-type, finely dispersed systems of the oil-in-water type and hydrodispersion gels, preferably as cosmetic or dermatological preparations. Despite their gel structure, these preparations are sprayable formulations which have a viscosity and / or yield point of over 2500 mPas to a creamy consistency. They can be sprayed by "normal" spray heads, since the shearing silicates collapse in the short term and reversibly due to the shearing forces that occur when pressure is applied to the spray head (feed pump) and the preparation becomes thin and sprayable (thixotropy). Normally, sprayable formulations must have a viscosity of less than 1000 mPas, better still less than 500 mPas (or water-thin), in order to be sprayable with normal spray heads.

Depending on the application, however, the amount dispensed from a spray pump is too low, so that many pump surges are necessary to z. B. enough preparation to disinfect or cream. However, because of the thixotropic properties of the preparations according to DE 103 43 851, dispensing from a container having a "normal" opening is likewise possible since it is not a matter of thin preparations.

For facial applications there is a risk of eye contact during spraying, which means that lotions that can be applied to the hand are a suitable alternative. In whole-body applications, however, spraying offers an advantage in terms of even distribution on the skin.

In the case of disinfectants, the application by means of a spray pump is ideal for surface disinfection, while for hand disinfection the preparation is taken directly from the normal discharge opening.

These advantages combine the packaging according to the invention, for. For example, skin protection and care products for face and body applications may be presented from a container.

According to the current state of the art, the manufacturer and the consumer of a preparation (as described, for example, in DE 103 43 851) are forced to use two containers, one with a spray pump and one with a 'normal' dispensing opening.

Market research has shown that consumers shy away from buying a second container with a normal dispensing opening and only purchase a container with a spray pump. The removal of larger quantities of preparation then takes place by simply unscrewing the atomizer pump.

However, the opening of the container has the disadvantage that germs can be introduced by contact with the external environment (eg contact of the suction tube with the depositing surface when the atomizer pump is deposited), which leads to the spoiling of the preparation. For many preparations z. B. be applied to surfaces or a living body, the use of preservatives is undesirable, so that only the absolutely necessary amounts are used. Contamination must therefore be largely excluded.

For a person skilled in the art surprising and unpredictable was that a container with two different output options, circumvents the problems outlined above. The invention relates to a container for preparations which are suitable both for the output from normal container openings and for spraying with atomizer pumps (pump sprayers).

The inventive container therefore has two different output options, a normal dispensing opening and a Zerstäuberpumpe.

It is also within the meaning of the invention instead of the atomizer pump, which produce a spray, to use pumps that allow a jet-shaped product output. This is z. B. in the technical field of advantage if the preparations are to be sprayed specifically to less accessible places (eg, lubricants, food, such as spice preparations, mustard, ketchup, decoration preparations).

According to the invention, the normal dispensing opening is closed by a hinged bumper, hinged screw cap, flip-top closure, push-pull closure, rocker arm bumpers, toggle screw caps or simple screw cap. The dispensing opening can advantageously be provided with a valve to better control the amount to be dispensed and prevent run-off of the contents.

The dispensing openings of the container according to the invention are advantageously embedded in different side walls, wherein the arrangement is preferred on opposite side walls. Under sidewalls here are all areas to understand that separate the content from the environment, thus the floor and head area.

It is particularly advantageous to let the normal discharge opening into the bottom of the bottle. The closure of this opening can be done by flip-top, push-pull or screw, with a high stability is given by the accumulating in the bottom area fluid (focus in the area of the bottom).

The container then has the advantages of a floor standing bottle, it can be delivered closed on one side and filled via the upper neck of the bottle. The upper neck of the bottle is closed after being filled by the atomizer pump. The container according to the invention relates to filling systems such as a conventional atomizer bottle, with which it can be processed on the conventional filling machines. In order to improve the emptying of the container, it is advantageous to form the bottom of the bottle curved, with the curvature facing away from the interior. The curvature reduces the volume area whose level lies below the recessed opening. Especially advantageous is the variant of the invention, in which the bottom is formed as a bottleneck and the base is formed only by the closure.

The first (usually upper) bottle opening has a removal pump, with no restrictions on the nature and operation. Advantageous pumps have a riser whose end is not cut vertically. It is advantageous riser pipes, which have a notch or oblique or cannula-like end, as this is the only way to prevent the riser end is closed by the wall of the container. It is also advantageous in terms of a better emptying, to make the riser so long that it does not push perpendicular to the container bottom, but rests obliquely.

The container according to the invention can be produced very expediently by injection stretch blow molding or extrusion blow molding.

All thermoplastic materials are suitable for the production, polyethylene, polypropylene or polyethylene terephthalate being particularly advantageous.

The containers according to the invention are very particularly preferably made from polyethylene terephthalate or laminates, since this material has a very high diffusion resistance and is thus suitable for a large number of preparations with sensitive ingredients.

The new multifunctional container according to the invention thus create the balancing act between a container with a spray pump and a container with a normal dispensing opening.

The pictures show:

Figure 1 multi-function bottle with screw cap in the bottom area and attached atomizer.

Figure 2 multi-function bottle with hinged bounce closure in the bottom area and attached atomizer pump. Figure 3 Different embodiments of riser ends a) crescent-shaped oblique end and b) V-shaped end.

Figure 1 shows an example of a container according to the invention, wherein the container body 10 at its lower and upper container end each having a threaded container neck 14 and 15. In the upper container neck 14, a spray pump 1 1 is used. From the atomizer pump 11 is a riser 12 to the bottom of the bottle, so that a good emptying is possible. The lower container neck 15 is closed by a screw cap (13) whose outer contour ensures stability. In the container neck 15, a perforated plate 16 is used, which restricts the removal amount.

Figure 2 shows another embodiment of a container according to the invention, in which case the container body 20 carrying the container necks 25 and 26 is closed by a spray pump 21 on the container neck 25 and by a hinged bounce closure 23 on the container neck 26. The hinge bounce closure 23 engages with the container body in the areas 24 with a nearly permanent connection is formed. Container body and hinge bounce closure have to pin and recesses, which interlock. The hinge lid 27 closes the remaining opening 28 reversibly.

In Figures 3a and 3b, two possible embodiments of riser ends are shown, which are not closed by contact with the container wall. 3a has a crescent-shaped bevel, in FIG. 3b the riser end is cut in a V-shape.

For the containers according to the invention, in particular the preparations listed in the examples are suitable. The matched to the containers of the invention consistency is achieved in particular by gel and structuring agents. In particular, one or more thickening agents are used, which or which can be advantageously selected from the group of polyacrylates, silicon dioxide, phyllosilicates, polysaccharides or their derivatives, for. Alginates, gellan gum, carrageenates, pectin, xanthan gum, hydroxypropyl methylcellulose,

Very particularly advantageous are polyacrylates from the group of so-called carbopols, for example Carbopols of the types 980, 981, 1382, 2020, 2984, 3128, 5984 and permulenes TR1, TR2, in each case individually or in combination. The preferred gel and structuring agents (in particular Permulen TR 1 and Carbopol 3128) are characterized on the one hand by very good emulsifying properties. On the other hand, they lead to a strong shear-thinning, rheological behavior, they form a strong structure, but collapses spontaneously under shear.

This property is described by the yield point. The yield stress is the critical shear stress of the flow curve.

The flow curve is measured on a shear stress controlled rheometer at 25 ⁰ C +/- 1 ⁹ C with 25 mm plate / plate geometry at a gap between 0.8 mm and 1, 2 mm, which is filled structure gentle. A suitable constant shear stress ramp is specified and a corresponding structure recovery time is maintained before the test and the critical shear stress with the associated viscosity is specified at the maximum of the flow curve.

A viscosity measurement, however, is carried out with the viscose VT 02 from Haake at 25 ⁹ C +/- 1 ⁹ C., spindle 1. The reading takes place after 30 seconds.

In particular, for cosmetic sunscreen preparations (see Examples 1 to 3), the containers according to the invention show great advantages, since the beach z. B. only one container must be taken.

Sunscreen preparations, in addition to the customary raw materials of the cosmetic preparations, also contain substances which protect the skin after application of the preparation from the action of harmful radiation (usually UVA and UVB radiation). Sunscreen filters are partially organic substances, such as. As cinnamic or triazine derivatives and partially also inorganic pigments. The following examples are intended to illustrate the present invention without limiting it. Unless indicated otherwise, all amounts, proportions and percentages are based on the weight and the total amount or on the total weight of the preparations. The flow curves measured for the example formulations A and C are shown in FIGS. 4 and 5. Clearly visible is the significant drop in viscosity in the range of 30 Pa shear.
