Description

Dispensing closure

Technical Field

The present invention relates to dispensing closures for metering a formula into a bottle containing a liquid.

Background

Some prior art solutions involve the possibility of adding ingredients, in particular in powder form, to bottles containing liquids, so that this step can be carried out only by the consumer who produces the beverage himself. The bottle contains mostly unflavored water to which a powdered mix or liquid syrup concentrated to flavor ingredients should be added later. This addition is completed until the flavouring substance previously contained in the capsule is in the bottle containing the water. The flavouring formulation is released from the small container by opening the closure, as in application HR20080441a2, or the powder or other substance is contained only within the chamber of the lid, which is unscrewed, pressed or unlocked to allow its contents to fall freely into the liquid in the bottle. Such a principle is known, for example, from documents US2009321380a1, US2010200536a1, KR20090055374A, KR20100019600A, JP2009083923A, KR20090052142A or KR 20090005510U. The individual solutions differ from each other in the procedure for opening the powder container after opening the bottle, or in the way they close the powder in the cap. Some of these solutions require a special form or size of bottle for their intended function. In some known solutions, the cap comprises several small containers of flavouring substances, but with their opening the entire quantity of contained ingredients is emptied without any possibility of controlling the quantity of powder poured into the bottle. All the above korean documents representing the most similar background art are not able to ensure complete pouring of the capsule chamber. Some of the filled substance may adhere to the small container wall and not enter the bottle. The mixture contained in the chamber after the membrane has been pierced falls freely and is not sure that the entire load is actually entered into the bottle at all times. It appears from the above document that some closures cannot be reclosed after the release of the powdered ingredient, which is why such beverages are suitable for immediate consumption and that such bottles with remaining beverage cannot be safely transported without risk of spillage. The internal mechanical systems of the caps are complex to assemble and therefore their main cost may adversely affect the final product price. The flavor intensity cannot be adjusted by controlling the amount of flavor formulation added and for caps with a particular bottle format, it is not possible to simply buy a cap with flavor and use it on a bottle that someone is using on their own.

Disclosure of Invention

The dispensing closure according to the invention comprises a closure body with a metering chamber, the principle being that the dispensing closure body has at its bottom at least two chambers which enter an upper guide part of the body in the form of a guide body, the cross section of which coincides with the cross section of the chambers at a transition point, in each chamber a piston is accommodated, which at its upper part has a catch which prevents unintentional unscrewing of the plastic cap and at its bottom side the piston is provided with a plastic cutter for piercing the cover foil, the body accommodating the piston being shielded from the upper side by a rotatably mounted plastic cap which features a detachable catch which prevents any interference, the chambers being closed from the lower side of the body by a cover foil. The chambers of the dispensing closure are formed in the form of equi-armed triangles, the longest side of which has the form of a circular sector. The piston is hollow in a direction from the circular side of the piston towards the center. The said detachable lock against interference is fitted with an accessory ring. The plastic cutter of the piston is shaped as an extension of the circular edge of the piston.

The dispensing closure according to the present invention has several advantages over the background art. One of these is that a dispensing closure with several flavoring substances can be used multiple times. Which can be used separately with bottles that have already been emptied. This has environmental savings and low plastics environmental pollution. When transported, for example on a trip, only one bottle and several closures that require little space need to be transported. The capped chamber may be filled with powder, liquid mixtures or even pills because it ensures that the contents are poured into the liquid contained in the bottle without sticking residues on the chamber walls.

Drawings

The invention will be explained in detail on the basis of the attached drawings, in which:

Fig. 3 includes a fully-deployed closure assembly of a plastic closure.

Figure 4 shows the release of the flavour compound by one stroke of the piston.

Detailed Description

The dispensing closure is designed such that it comprises a body 1 with three chambers 3, said three chambers 3 entering (forcing intos) an upper guide portion of the body 1 in the form of a guide body 2, the cross section of which coincides with the cross section of the chambers 3 at the transition point. In each chamber 3a piston 4 is arranged, which in its upper part has a catch preventing unintentional unscrewing of the plastic cap 5, and in its bottom part the piston 4 is provided with a plastic cutter for piercing the cover foil 6. The body 1 containing the piston 4 is shielded from the upper side by a rotatably mounted plastic cover 5, which features a detachable catch 7 that prevents any interference. The chamber 3 is closed from the underside of the body 1 by a cover foil 6. The chamber 3 of the dispensing closure is formed in the form of an equi-armed triangle (equi-triangular) with the longest side in the form of a circular sector. The piston 4 is hollow in the direction from the circular side of the piston 4 towards the centre. The detachable locking catch 7, which prevents any interference, is fitted with an attachment ring. The plastic cutter of the piston 4 is shaped as an extension of the circular edge of the piston 4.

The dispensing closure is filled such that the chamber 3 is in an inverted position, with the bottom facing upwards, filled with the desired flavouring substance and closed by an aluminium foil 6. The dispensing closure with the snap ring is then screwed onto the bottle and the latter is so snapped as to prevent unintentional opening. Using a part of the plastic cover 5 with a detachable catch 7, one of the three pistons 4 can be accessed after pulling out the detachable catch 7. By rotating (twisting) the opening in the plastic cap 5, the desired flavour component is selected in the chamber 3. When the plastic cover 5 is rotated clockwise over a step on the piston 4, the step represents a catch that prevents unintentional twisting of the plastic cover 5. By pushing the piston 4 with the plastic cutter on the annular cutting edge of the piston 4, the cover foil 6 located below the selected piston 4 is pierced and the contents 8 of the chamber 3 are released into the bottle onto which the dispensing closure is fitted. After the bottle is emptied, the dispensing closure is rotated open, the bottle is again filled with fresh water, and the dispensing closure can be screwed on. It is therefore possible for the dispensing closure to be used for so many bottle fillings, depending on how many chambers 3 the dispensing closure comprises. The dispensing closure is designed for 38mm screw-top bottles.

Industrial applicability

The dispensing closure according to the present invention for metering flavouring ingredients into a bottle containing a liquid can be used for any kind of drink demand, and the end consumer can prepare his drink with his own desired taste and quantity. It is therefore used in the beverage branch of the food industry.
