Description

Dispensing cap with internal chamber
Field of technology
The solution falls in the field of packaging technology and it concerns a dispensing cap with an internal chamber, intended particularly for beverage bottles.
State-of-the-art
A large number of technical solutions describe the end-user-controlled dosage of a flavouring agent into a beverage bottle, with the bottle usually containing water in which the flavouring agent is to be dissolved.
HRP20080441 file describes an elongated cartridge passing through the bottle with water from the lid to the bottom. The cartridge is provided with side openings that are open by the mechanism linked to the bottle cap thereby mixing the flavouring agent with the water in the bottle. Sufficient mixing of the flavour with the water appears to be problematic. Another possible solution is to store the flavouring agent, whether powdered or liquid, in a chamber formed in the lid itself. Upon turning, pressing or unlocking a safety lock, the chamber opens and its contents is mixed with the liquid in the bottle. This principle is described for example in US2009321380A1 , US2010200536A1 , KR20090055374A, KR20100019600A, JP2009083923A,
KR20090052142A or KR20090005510U. WO2011/027177A1 file describes a solution in which the flavouring agent is placed in the cavity of the piston passing through the cap where it is integrated as a part; with covering foil penetrated the bottle must be shaken thoroughly to ensure complete emptying and flushing of the cavity into the contents of the bottle. The dosage of the mixture from the cap-formed chamber is also described in W02008110767A2, where the chamber is linked to the bottle contents only by a narrow pressing-in slot which only allows the liquid flavouring agents to be dispensed. The solution includes a telescopic piston which must first be activated to the working position before the liquid flavouring agent is driven into the bottle itself. Many of these solutions require a special type of bottle that is compatible with the cap and they cannot be used more generally for ordinary types of bottles. EP1737743 describes a double-acting container cap having an auxiliary space for storing the flavouring agent which is separated from the contents of the bottle by a sealing foil. A mandrel is located in the cap, extending vertically into the auxiliary space of the cap. The mandrel bottom is fitted with a piercing device to penetrate the sealing foil. Here, the auxiliary space in the cap is too small and is further reduced by a too large piercing device. Consequently, after mixing with the contents of the bottle, the flavouring effect is not sufficient, even with a seemingly small bottle volume of 300 ml. The content of such a small space allows only highly concentrated mixtures to be dosed, which must be significantly flavoured prior to filling, and this small space precludes the use of natural chemically unmodified mixtures, whether loose or liquid, the use of which in the bottle volumes of 300 to 500 ml would not sufficiently flavour the contents. The hitherto available solutions do not allow to follow the trends mainly in the field of healthy nutrition or in the fields where minimal technological intervention is required in the quality of flavouring agents, just because of the inability to apply the flavouring agent in such a quantity that would ensure a sufficiently intense taste of the bottle content. Another problematic issue is the fact that the mandrel is fitted to the cap body only by two or three plate-like elements which do not provide sufficient guidance and their sealing function is questionable too. Dispensing cap with internal chamber for flavouring agent and a mandrel with penetrator of the sealing foil is also described in EP2217508. Even with this solution, the location of the mandrel in the cap body incorporates the plate-like elements whose sealing and specifically guiding function is problematic. In addition, the design of the mandrel as a single piece does not allow more versatile use for different cap dimensions and the different volume of the flavour agent chamber, and the continuous filling of the internal chamber intended for the loose or liquid component as it prevents direct access of the filling device to its space, thereby greatly reducing accuracy and the speed of application in the production line. The present solution assumes that the said cap is filled at the moment when the piercing mandrel is not yet seated therein; instead it is inserted into the cap immediately after automatic filling of its internal chamber with a loose or liquid mixture, and subsequently the space is closed by a membrane.
The aim of the present technical solution is to present a dispensing cap with an internal chamber which is intended to contain a flavouring agent and which is separated from the bottle contents by a thin foil, the tearing of which leads to the flavour agent being mixed with the contents of the bottle, with a sufficient variability of the internal chamber volume ensured as well as its perfect emptying into the contents of the bottle and easy handling of the cap on the production and packaging line.
Main features of the technical solution
The objective is achieved by a technical solution which incorporates a dispensing cap comprised of a body that is formed by a cylindrical casing with a bottom-open and sealable internal chamber, where the cylindrical casing is provided with a coaxial mouthpiece nozzle at the top. The mouthpiece encompasses at least one through-flow passage leading into the internal chamber and a penetrating rod that is axially mounted and sliding in the through-piston cavity formed in its longitudinal axis. The mouthpiece nozzle features a mouthpiece that slides axially. The mouthpiece has a coaxial opening that is fitted with a closing flap in the form of an annular ring around the mouthpiece opening. The invention basically involves a penetrating rod that consists of demountable interconnected elements and a piercing mandrel, whose pushing element is placed in the piston cavity by means of a piston segment. The cross section of the piston segment corresponds to the inner cross section of the piston cavity. The middle part of the internal chamber, around its inner surface, features at least one chamber edge which divides the internal chamber axially into two or more parts. Every single part has a greater cross-section area than the one located above it.
The present invention achieves a new and a higher effect by retaining a compatible thread and enabling the use on bottles with various volumes. By a simple change of one part of the penetrating rod some other components can be used for a different volume of the internal chamber for the flavouring agent, thereby reducing the production costs and the dismountability of the rod also has a positive effect even when the inner chamber is being filled. Explanation for drawings
Specific examples of the technical solution are shown in the accompanying drawings which present:
Fig.1 a cross section view of the cap in the basic locked position with the penetrating rod in its upper end position, intact membrane and the lid attached,
Fig.2 a cross section view of the cap with the lid removed, the mandrel compressed, the membrane penetrated and the mouthpiece in its lower end position,
Fig.3 a cross section view of the cap with the mandrel compressed, the membrane penetrated and the mouthpiece in its upper end position,
Fig.4 an axonometric bottom view of the penetrating rod in an as-assembled condition.
The drawings illustrating the submitted technical solution and the following examples of a particular design do not, in any way, limit the scope of protection stipulated in the definition, yet merely illustrate the principle of the technical solution.
Examples of applied technical solution
The dispensing cap with the internal chamber, as illustrated in Fig. 1 to 3, comprises a cap body 1 formed by a cylindrical casing 11 in which a bottom-open internal chamber 1 12 is formed. Its outside bottom is fitted with a coaxial mounting element 12 that can be fixed to the opening of a container (not shown) and its upper area features a coaxial mouthpiece nozzle 13 whose outside surface is fitted with a hat-shaped mouthpiece 2 that can slide axially. A mouthpiece opening 22 is formed coaxially around the axial axis of the mouthpiece 2. The mouthpiece 13 incorporates along its axis a piston cavity 131 extending from above into the internal chamber 1 12 and at least one throughflow discharge channel 132 provided in the annular ring around the piston cavity 131 also leading from above to the internal chamber 1 12 . The discharge channel 132 is radially overlapped from above by the closing flap 21 of the mouthpiece 2^ wherein the sealing lip 211 of the flap 21 fits into the upper mouth of the discharge channel 132 when the mouthpiece 2 reaches its lower end position. The penetrating rod 3 is placed in the cap body 1, it can slide axially. The rod consists of a pushing element 31 whose piston segment 311 runs through the piston cavity 131. and a removable piercing mandrel 32 that is connected to the rod. The mandrel is situated in the internalchamber1 12 and its end features at least one penetrating edge 321. The cross section of the piston segment 311 corresponds to the inner cross section of the piston cavity 131 which is sealed by the piston segment 31 1. The lower end area of the pushing element 31 is provided with a flat sealing element 312 and its upper end area is fitted with a button 313. If the penetrating rod 3 is in its upper end position, the flat sealing element 312 fit tightly to the mouth of the discharge channel 132 into the internal chamber 112 and the upper edge of the button 313 overlaps the upper edge of the mouthpiece nozzle 13. In this position of the penetrating rod 3, the penetrating edge 321 is at the level of the plane defined by the circumference of the lower edge of the cylindrical casing 1 1_. The internal chamber 112 can be closed at its lower end by a membrane 113. In the central part of the inner chamber 112, at least one chamber edge 114 is formed around the circumference of its unlabelled inner surface, through which the internal chamber 112 is divided axially into two or more unlabelled parts. Every single part has a greater cross-section area than the one located above it. The mouthpiece 2 can be covered with the lid 4.
Industrial usability
The dispensing cap with internal chamber is useable in the food processing industry, especially for beverage bottles.
