Abstract

The present invention relates to a stopper with a container, consisting of the top of the stopper (1), the central part of the stopper (2), the working part of the stopper (3), the bottom of the stopper (4), the seal or the sealing foil (5); and which is filled with substance (6). The top of the plug (1) is threaded to the central part (2), which is tied to the bottom (4) by a bayonet type of tying. The central portion (2) can rotate independently of the bottom (4) around the longitudinal axis of the plug or only in the preferred direction. The working part (3) is located in the space of the central part (2). Rotation of the central part (2) with respect to the bottom of the plug (4) leads to the movement of the working part (3) with respect to the central part of the plug (2) and the bottom of the plug (4). The bottom of the cap (4) is designed to be easily penetrated by the workpiece (3). The advantages of this technical solution are that the top of the plug (1), the central part (2) and the bottom of the plug (4) can be arbitrarily shaped since they do not perform relative relative motions along the axis of symmetry.

Description

The field of technology

The present invention relates to a cap with a container. The technical field of the subject invention can be classified generally into container closures (caps); which are combined with other devices that do not have the role of closure; and where the closure, i.e. the cap, serves as a means of accommodating additional material. This material comes into contact with the main contents of the container through the action of the closure part - and without opening the closure itself - where the activation is done by rotating or turning the closure part.

Technical problem

The first technical problem solved by the invention in question is the improvement of the existing caps with a container, where, when opened, there is a space for the flow of liquid from the container without visible partition parts in the cap itself.

Another technical problem solved by the invention is the possibility of forming an arbitrary external appearance of the cap without impairing the functionality of the cap with container and its use on standard PET packaging.

State of the art

The state of the art for the subject invention is very rich. The use of the present invention is primarily directed to containers containing a drinkable substance, eg water, and where the cap itself contains a second substance (powder or liquid) that comes into contact with the first substance from the container by activating the cap of the container. The subject invention belongs to a set of technical solutions where said second substance stored in the cap comes out from the bottom of the cap into the main container where the substance from the container and the substance from the cap are mixed.

The first family of technical solutions discloses caps in which the relative rotation of the cap or part of the cap with respect to the base container leads to a puncture of the bottom of the container, where parts of the punctured bottom remain attached to the cap. Just by breaking through the bottom of the cap, the substance from the cap comes into contact with the substance in the base container. One such technical solution is provided by International Patent Application PCT/KR2007/005158, published as WO2008/048077A1 by PARK, Jeong-Oog. As can be seen in Drawing 4 of the same patent application, the piercing parts and the pierced lower part are visible from the user's position and do not appear aesthetically pleasing to the user who is used to seeing only the liquid of the basic container or the bottom of the basic container.

The second family of technical solutions represents a subset of the first family of technical solutions where only the piercing of the bottom of the container and the parts of the cap that perform the piercing are not visible to the user. Such a solution is given for example in the international patent application PCT/US2003/025987 published as WO2004/103853A1 of the applicant GIBLER, Gregory, A. This solution of the technical problem represents the closest state of the art according to the subject invention.

The main difference between PCT/US2003/025987 and the present invention is the number of component parts of the caps, which is admittedly greater in the present invention, but whose construction at the same time allows the exterior of the cap to remain unchanged before and after the bottom of the container is pierced in the cap. Such a construction gives stopper designers much more freedom in the creation of stoppers, since the stoppers with containers on the market are not small in size (see, for example, www.cedevitago.com) and are used with non-standard containers.

The essence of invention

The present invention relates to a cap with a container, which consists of the top of the cap (1), the central part of the cap (2), the working part of the cap (3), the bottom of the cap (4), a seal or sealing film (5); and which is filled with substance (6). The top of the cap (1) is threaded to the central part (2), which is attached to the bottom (4) with a bayonet type of connection. The central part (2) can be rotated independently of the bottom (4) around the longitudinal axis of the cap in both directions or only in the preferred direction. The working part (3) is located in the space of the central part (2). The rotation of the central part (2) in relation to the bottom of the plug (4) leads to the movement of the working part (3) in relation to the central part of the plug (2) and the bottom of the plug (4). The bottom of the cap (4) is made so that it can be easily penetrated by the working part (3). The advantages of this technical solution are that the top of the plug (1), the central part (2) and the bottom of the plug (4) can be shaped arbitrarily, since they do not perform relative movements along the axis of symmetry.

Detailed description of the invention

Drawing 1 shows all the details of the cap with container according to the subject invention in a longitudinal section. The cap consists of five basic parts:

- top of the cap (1),

- the central part of the cap (2),

- the working part of the plug (3),

- the bottom of the cap (4), i

- seal or sealing film (5), a

the cap is "filled" with a substance (6) that can be liquid or powdered. The mentioned substance (6) is mixed with the substance from the basic container after activation. The arrangement and appearance of each of the basic parts (1)-(5) is given in drawing 2. On parts (1), (2), (3) and (4) the positions of the threads are visible, the function of which will be discussed in more detail in the text.

Drawing 3 shows the top of the plug (1) which consists of the part (1.1) that rests on the central part of the plug (2), more precisely at the position (2.1); thread (1.2) - which is compatible with the thread (2.2) of the central part and, if desired, the derived upper part (1.3). The only technical requirement that is imposed on the top of the cap (1) is that it can be tightly threaded onto the central part of the cap (2) and form a whole with it. The inside of the plug must be formed with cylindrical symmetry for the sake of the thread, while the outside can be made arbitrarily.

Drawing 4 shows the central part of the cap (2). The position (2.1) has the role of abutting on the position (1.1) and stopping the top of the cap (1) which is wound onto the central part of the cap. There are no other requirements for thread (2.2) apart from compatibility with thread (1.2), and threads (1.2) or (2.2) can be made "steep" if desired. Position (2.3) represents the place where the seal or sealing foil (5) rests during the assembling and filling phase of the cap. Position (2.4) refers to the outer body of the central part of the plug (2). The outer body (2.4) must have internal cylindrical symmetry, while the outside can be formed as desired. In drawing 4, the outer part of the body (2), i.e. (2.4), has a cylindrical shape for easier understanding of the functionality of the invention.

Position (2.5) refers to the longitudinal grooves made inside the body (2.4). The minimum number of slots (2.5) for the functioning of the invention is 1, and there can be any number of them. A sufficient number of slots (2.5) for the good functioning of the invention is 2 or 3, and preferably they are distributed equidistantly - but this is not a requirement. Longitudinal grooves (2.5) made in (2.4) extend continuously to the cylindrical cavity (2.6) and form a whole with it, drawings 5 and 6. The technical role of the grooves (2.5) is to serve as guides for the protrusions (3.1) of the working part of the plug which moves within the space (2.9) and in the last phase within the cavity (2.6). Drawings 5 and 6 show cross-sections A-A and B-B of the body (2.4).

The position (2.7) is axially symmetrical and serves for a snap-on grip (for bayonet-type fastening) of the position (4.1) of the lower part of the plug, while the position (2.8) rests on the position (4.2). This results in the connection of the central part of the cap (2) with the bottom of the cap (4) in such a way that the central part (2) can be rotated independently of the bottom of the cap (4) around the longitudinal axis of the cap and that the central part of the cap is still tightly connected ( 2) and the bottom of the plug (4). This function is of the utmost importance for the perfect functioning of the subject invention, which will be discussed in more detail.

The working part of the plug (3) is shown in drawing 7, i.e. its section C-C in drawing 8. The role of the working part (3) is to move inside the bottom of the plug (4), more precisely its space (4.5) and break it (4.9) so that the substance (6) from space (3.4) of the working part brought into contact with the contents of the main tank. Position (3.1) is embossed on part (3.2), see drawing C-C. The number of positions (3.1) and the size of the part (3.2) are dimensionally made to match the number and size of the guides (2.5) and the inner diameter (2.4) on the central part (2) in such a way that the guides (2.5) and the part (2.4) they do not offer resistance to the movement of part (3.2), but still spatially fix it. Space (3.4) contains substance (6) and is bounded by part (3.3) whose outer diameter is slightly narrower than (3.2). On the lower part of the working part (3) there is a thread (3.5) which is compatible with the thread (4.4) on the bottom of the plug (4).

The role of the beveled part (3.6) enables the movement of the working part (3) relatively downward inside the bottom of the cap (4) to push the substance (6) into the area (3.4). The tip (3.7) has the role of piercing the very bottom (4.9) of the cap.

The bottom (4) of the plug is shown in drawing 9, i.e. its cross-section D-D in drawing 10. The role of positions (4.1) and (4.2) as well as the bayonet connection with positions (2.7) and (2.8) on the central part (2) of the plug it has already been explained earlier. In its central part, there is an external body (4.3), which on the inside has a thread (4.4) compatible with the thread (3.5), while on the outside it can be shaped according to the designer's wishes. Through the body (4.3) extends the volume (4.5) within which the working part (3) of the stopper moves. Position (4.6) carries a thread compatible with the thread on the bottle or container on which the cap according to the subject invention will be mounted and which enters the space (4.7) through the neck wall. The wall (4.8) separates the space (4.5) from the wall of the neck of the external tank and on its lower part has an attached or glued circular derived part (4.9) which can be broken through with a relatively small force/pressure. Such part (4.9) is known in the state of the art.

The relative circular movement of the bottom of the plug (4) in relation to the central part (2) drives the working part (3). In doing so, the working part (3) can be moved both up and down relative to the central part (2). In order to prevent the working part from moving upwards, it is necessary to specially design the contact sliding surfaces of the bottom of the plug (4) and the central part of the plug (2), more precisely surfaces (4.2) and (2.8).

Drawing 11 shows a section E-E of drawing 9. Drawing 11 shows a sliding surface (4.2) equipped with grooves (4.2') having a triangular shape cut into the material as shown in detail G of drawing 13.

Drawing 12 shows a section F-F of drawing 4. Drawing 12 shows a sliding surface (2.8) equipped with elastic wings (2.8') which rise from the surface on one side as shown in detail H of drawing 14.

The wings (2.8') are free at one end and raised above the surface (2.8) - drawing 14. When the end of the wing (2.8') which is raised from the surface (2.8) is pressed against the surface (2.8) - then the wings can sink into it in in its entirety. Dimensionally, the wings (2.8') are designed to be smaller than the surface of the slots (4.2') so that the wings (2.8') can rise up into the slots (4.2') and enter them completely. Also, it is desirable that the number of positions (2.8') and (4.2') be equal and that their positions correspond.

Drawing 15 shows the sliding of the surface (2.8) on (4.2) when the wings (2.8') do not correspond to the grooves (4.2'). Surface movement is possible in both directions as indicated by the arrows.

Drawing 16 also shows the sliding of the surface (2.8) along (4.2), but for the case when the wings (2.8') are above the grooves (4.2'). It is clear that the relative movement of the surfaces is now possible only in the direction of the arrows in drawing 16, because the wings (2.8') normally stick in the grooves (4.2'), which defines the preferred direction of the relative movement.

Such a construction of surfaces (4.2) and (2.8) with grooves (4.2') and wings (2.8') enables relative movement of the working part (3) only towards the position (4.9) of the bottom of the plug (4).

Assembling and filling the cap with the container according to the subject invention is relatively simple. All parts are molded from a suitable plastic - but this is not a requirement for the invention to function.

The working part (3) is screwed onto the bottom (4) of the container - as shown in drawing 17A - to the depth as shown in drawing 17B. On the parts placed in this way, making sure that the elements (3.1) enter the guides (2.5), the central part (2) is firmly pressed in order to achieve a solid connection between the bottom (4) and the central part (2) of the plug (see drawing 17C - below) . The "height" of the working part (3) inside the central part (2) is made such that the elements (3.1) are located almost at the top of the guides (2.5).

Now powder or liquid can be placed in the space (3.4) and sealed with a gasket or sealing film (5). Finally, the top of the plug (1) is screwed onto the entire structure.

Optionally, it is also possible to thermally join the plug (1) and the central part (2) or cover it with foil to obtain an easily separable connection between parts (1) and (2). This finally results in the filled structure shown in drawing 1, which is ready to be placed on a tank.

The method of using the subject invention is shown in the series of drawings 18A - 18F. Drawing 18A shows the cap with the container in the initial stage before it has been used. When the user wants to (and) use the cap, he grasps the tip (1) and/or the central part (2) of the cap with his hand and starts rotating them clockwise, looking from above. Such action causes the winding of the working part (3) inside the bottom (4). The result of such action can be seen in drawing 18B, the working part (3) begins to descend inside the central part (2). Continuing to rotate (1) and (2) brings the working part (3) to the critical position shown in drawing 18C when it touches the position (4.9) of the tank bottom. During this time, the bevel (3.6) pushes the substance (6) into the space (3.4), which prevents contamination of the threads. Further rotation results in perforation (4.9) as shown in drawing 18D and discharge of substance (6) into the base container. Even further turning (1) and/or (2) finally brings the working part (3) into a position where it can no longer be moved by (2). Namely, the protrusions (3.1) finally come into the space (2.6) and the higher turning (2) does not drive (3) inside the thread (4.4). The user "feels" this condition as a loss of resistance when turning part (2). In this position, the thread (3.5) secures the parts of the position (4.9) in a constant position as shown in drawing 18E.

Finally, the contents from the base container and the substance (6) from the cap are mixed and ready for use. If a breakable connection between the top of the plug (1) and the central part (2) was formed, it is now broken or removed and then it is possible to unscrew the top of the plug (1) from the central part (2).

This is followed by the unsticking (or removal) of the seal or sealing film (5), which enables consumption or other application of the mixture, after which the top of the cap (1) can be re-screwed/removed onto/from the central part of the cap (2) an arbitrary number of times.

Industrial applicability

The industrial applicability of the subject invention is unquestionable. This kind of cap with a container is extremely suitable for external design since the activation of the cap does not change its external shape, see for example drawing 19. Also, the view into the basic container after the cap is activated does not differ from a standard cap; you can see the liquid or the bottom of the bottle.
