Definitions
- the present invention relates to a container with its closure, said container being substantially cylindrical in shape and having a neck with a rim on which is welded a membrane and said closure comprising a bottom and a skirt at the periphery of said bottom and perpendicular to it, the inner part of the skirt comprising a thread intended to cooperate with the external thread of the container.
- jar closure systems substantially cylindrical shape, in which it is provided inside the cover a cushion.
- the advantage of having this cushion is that it allows after the first opening to guarantee a secondary seal, that is to say the seal during jar closings.
- the jar is closed with an aluminum seal which is sealed by induction on the opening of said jar.
- the problem with the current solution is that on the one hand the cushion is expensive and on the other hand, there must be a step additional to combine it with the seal before depositing it inside the lid.
- US Patent 4,531,649 the basis for the preamble of claim 1, relates to a jar closure system, in which we seal by induction a composite membrane on the rim of the jar and we have a closure with a system of three lips concentric.
- the utility model GM 8133968 also consists of a three-way locking system lips and in this case also, there is a risk of fusion of said lips at the time of induction sealing.
- the object of the present invention is to develop a cover in a single part and which would however guarantee a secondary seal equivalent to that obtained with the cushion with a sealing system with aluminum jar.
- the present invention relates to a container with its closure, said container being of substantially cylindrical shape and comprising a neck with a rim on which is welded a membrane and said closure comprising a bottom and a skirt at the periphery of said bottom and perpendicular to it, the inner part of the skirt comprising a thread intended to cooperate with the external thread of the container, in which the membrane is welded by induction on the edge of the container and the interior of the bottom of the closure has near the skirt a system of three concentric lips, namely inner lip, middle lip and outer lip, intended to rest on the rim of the container, the lip outer has a height x greater than the height y of the inner lip and the median lip a height z less than that of the inner lip, the distance which separates the inner lip from the outer lip corresponds substantially to the thickness of the container on which said closure is placed.
- the closure according to the invention is particularly suitable for containers comprising a membrane which is an aluminum sheet, the sealing of said membrane on the upper edge of said container having been made by induction.
- this induction sealing is done with the contents and with the closure and the membrane already in place.
- the presence of the three aforementioned concentric lips having different heights allows in any case three functionalities: the lip outer guarantees proper positioning of the membrane before the lip interior does not plate the membrane by partially deforming it around the rim of the container at the time of induction sealing and the middle lip guarantees after the first opening a good secondary seal.
- the lip median is the shortest of the three, the said tightness is totally guaranteed secondary.
- a middle lip is provided having a height less than both other lips, that is to say a lip which does not touch the rim of the neck of the container.
- the closure according to the invention is particularly suitable for plugging glass or plastic jars containing powdered products, such as cocoa powder or instant coffee powder.
- these two lips are normally arranged at a distance which corresponds substantially to the thickness of the jar on which is placed said cover. This distance is normally between 1 and 4mm. Regarding the height of these same lips, it is included for the height x between 4/10 mm and 4 mm, for the height y between 1/10 mm and 3 mm and for the height z between 5/100 mm and 1.8 mm.
- decreasing lip heights are provided, from the lip outer to the middle lip.
- outer, inner and middle lips respectively of height 1.5, 0.8 and 0.6 mm.
- the closure (1) comprises a bottom (2) and a side skirt (3).
- the interior of the skirt includes a thread (4) for hanging on the corresponding thread of the container containing the product to be stored.
- the closure is normally in plastic, such as high density polyethylene or polypropylene.
- the closed is preferably in the latter material. We can see on the figure that part A comprising the three concentric lips is located on the face inside the bottom and close to the skirt.
- FIG. 2 clearly shows the three-lip system.
- the outer lip (5) has a height x higher than the height y of the inner lip (6).
- the middle lip (11) is the one with the smallest dimension z.
- Figure 3 shows the closure (1) arranged for closing the container (7).
- the outer (5) and inner (6) lips rest respectively on the outer (8) and inner (9) parts of the rim (10) of the neck (13) of the container. After delamination of the membrane (12), it is the middle lip ( 11) which fully guarantees the tightness of the closure.
- the shape of the lips is not critical. We can very well consider them, seen in section, triangular in shape as in Figure 2. But it is also possible to have them in the form of tabs, as in figure 3. The only obligation is that the middle lip does not touch, at the time of sealing, the rim (10) of the container.
