Abstract
Description
- The present invention relates to a container.
- In particular, it relates to a container equipped with a cap, preferably of the flip-top type.
- Caps, especially flip-top caps, are usually snap-fitted onto bottles or flasks. In this way, such caps cannot be removed. To demonstrate the integrity of a product, the flip-top cap can feature a breakable seal located near the openable part of the cap.
- Alternatively, caps can be screwed to flasks or bottles which have standardised necks featuring threads. The screwing-fitting thereof, is carried out using automatic machines. In this case, it is often useful to seal the cap and part of the container with a film to demonstrate that the cap has not been unscrewed and therefore the contents are intact.
- However, the film must be applied after the container has been filled, which is particularly inconvenient.
- Furthermore, this film is not very ecological as it must be disposed separately from the container.
-
- The object of the present invention is to provide a container which is an improvement on the prior art.
- A further object of the invention is to provide a container which is more environmentally compatible than those according to the prior art.
- A still further object of the invention is to provide a container wherein the removal of the cap is essentially prevented but the cap can still be fitted by means of the automatic machines already used for standard threaded necks.
- This and other objects are achieved by means of a container according to the technical teachings of the claims annexed hereto.
- Further features and advantages of the innovation will become clearer in the description of a preferred but not exclusive embodiment of the device, illustrated - by way of a non-limiting example - in the drawings annexed hereto, in which:
-
Figure 1 is a perspective view of a cap of a container according to the invention, in the open configuration; -
Figure 2 is a side view of the cap inFigure 1 ; -
Figure 3 is an axial sectional view of the cap inFigure 1 ; -
Figure 4 is the axial sectional view inFigure 3 viewed from another angle; -
Figure 5 is a partial axial sectional view of the container according to the present invention; and -
Figure 6 is an enlarged view of the detail circled inFigure 5 . - With reference to
Figure 5 , reference number 1 is used to denote, as a whole, a container. - The container 1 comprises a hollow body 8 (shown only partially in
Figure 5 ), which can have any shape. Thehollow body 8 features, in proximity to the opening 5, afirst thread 7. - The container also comprises a
cap 6, which is shown separately inFigures 1 to 4 . Thecap 6 comprises a substantiallycylindrical body 2 equipped with a dispensingport 3 and asecond thread 4 for coupling with thefirst thread 7 on thehollow body 8. - According to the invention, one of either the
first thread 7 or thesecond thread 4 is axially discontinuous. - In the configuration illustrated in the figures, the
first thread 7 is provided on a neck of thehollow body 8, while thesecond thread 4, which is the axially discontinuous thread, is provided on thecap 6. Obviously, a mirror configuration (not shown) is possible. - In this text, the term 'axially discontinuous' means that the thread has interruptions arranged in an axial direction. In other words, there is at least one plane (or rather a strip) - perpendicular to the container axis A - in which the thread is not present, but it is present both above and below the said plane or strip.
- Essentially, the axially
discontinuous thread 4 can be provided on a substantiallycylindrical surface 12. - In this text, the term 'substantially cylindrical' means a perfectly cylindrical or only slightly tapered surface, with a taper of between 0° and 2°.
- This taper may be useful to facilitate mutual centring of the hollow body and the cap.
- The substantially
cylindrical surface 12 can comprise a first substantiallycylindrical portion 12A featuring afirst part 10 of thediscontinuous thread 4, a second substantiallycylindrical portion 12B without a thread (corresponding to the said plane or strip), and a third substantially cylindrical portion featuring asecond part 11 of thediscontinuous thread 4. - The
second portion 12B can be interposed between thefirst portion 12A and thethird portion 12C. - The
second portion 12B can be configured to house aflange 14 in such a way that when theflange 14 is located in the saidsecond portion 12B, it is difficult or impossible to unscrew thecap 6 from thehollow body 8. - The
flange 14 can be radially continuous, essentially as already featured on the standard mouths of threaded flasks or bottles according to the prior art. - Alternatively, the said flange can be radially discontinuous, formed of a series of teeth or protuberances aligned on a plane.
- Advantageously, the
flange 14 has a perimeter such as to engage in an undercut manner with thefirst thread 7 on the hollow body 8 (or at least with the crest of the said thread) when the thread is engaged (or at least partially in contact) with theflange 14. - The
first part 10 of thediscontinuous thread 4 can extend axially in such way that when theflange 14 is positioned in thesecond portion 12B, thefirst part 10 of the discontinuous thread is disengaged from thethread 7. - This can be achieved by gauging the thread pitch so that it is, for example, between 0.5 mm and 20 mm, advantageously between 2 and 6 mm, and even more advantageously approximately 3 mm. Obviously the pitch should be optimised according to the cap diameter, which can be anything.
- Furthermore, the circumferential length of the
first part 10 of thethread 4 can be three quarters of a turn (i.e. 270°) and, in any case, less than a full turn (i.e. less than 360°). - Advantageously, the
first part 10 of the discontinuous thread and thesecond part 11 of the discontinuous thread have the same pitch and circumferential length. - The
second part 11 of thethread portion 11A which is substantially perpendicular to an axis A of the container, the saidportion 11A being preferably adjacent to the saidsecond portion 12B. - In this way, once the flange is interposed between the first and the second part of the thread (see, for example,
Figure 6 ), it is difficult to unscrew the cap since the substantially perpendicular part of the thread slides over the flange, without allowing the flange to 'hook' or engage the said thread. - In the figures shown here, the axially
discontinuous thread 4 is provided on an internal surface of saidcap 6, and the saidflange 14 is provided on an external surface of the saidhollow body 8; preferably the substantiallycylindrical surface 12 is an internal surface of the saidcap 6. - As already mentioned, however, a perfect mirror configuration is also possible, in which the axially discontinuous thread is provided on an external surface of the said
hollow body 8, and the said flange is provided on an internal surface of the said cap; preferably the substantiallycylindrical surface 12 is an external surface of the saidhollow body 8. - Advantageously, the
cap 6 is of the flip-top type and comprises alid 6A configured to hermetically seal theport 3 in the body of thecap 6. - Advantageously, the
cap 6 is made of a single piece of a plastic material. - The hinging 21 between the body and the lid can be made as a single piece, in a conventional way, by injection moulding a plastic material. Furthermore, the cap can also feature a
sealing lip 20 which cooperates with themouth 5 of thehollow body 8, again made as a single piece. - By way of example, the cap can be made of one or more of the following plastic materials: PP, PE, PA, and PLA, and possibly also appropriate 'green' or 'bio' materials.
- Between the
lid 6A and the cap there may be a seal (of a conventional kind, not shown) which shows that the cap has been opened. - It has been seen that the invention is particularly effective, since the cap can be mounted on hollow bodies (bottles, flasks etc.) with a standard screw neck, produced with standard design preforms.
- Furthermore, the cap can be fitted using the fitting machines already used for screwing on standard caps.
- The greatest advantage of the axially discontinuous thread is that the cap can be 'locked' on to the container in such a way that it cannot be tampered with or detached from the container during normal product use.
- This results, therefore, in the elimination of the protective film (usually of the heat-shrinkable kind), which is both a pollutant and hard to recycle.
- Furthermore, there is the indubitable advantage that a step which comes after the filling and closing of the container (i.e. the film application step) is eliminated, thereby reducing the cost of the finished product as well as production times.
- A container of this kind is particularly useful for bottles containing oil or, in any case, edible products, which cannot therefore be refilled (except through the
port 3 in the cap, which is very difficult). - Furthermore, it should be emphasized that a cap according to the invention remains permanently secured to the bottle or flask and is very hard (almost impossible) for the end user to remove.
- Various embodiments of the innovation have been disclosed herein, but further embodiments may also be conceived using the same innovative concept.
