ABSTRACT:
The present invention concerns a packaging container with a closure means.
BACKGROUND OF THE INVENTION
Different means have been proposed in state of the art technology in order to prevent unwanted opening of a packaging container and/or, in a case of unauthorised opening, to make this opening process irreversible and therefore show this to subsequent users. Such sealing plays a particularly large part in packaging of foodstuffs, where particularly hygienic conditions are involved and where product consumers want to be sure of obtaining undamaged and irreproachable goods.
With use of containers as packaging, particularly for pourable goods such as spice powders, herbs or powder-form foodstuffs, there are primarily two sealing methods which are known. With first such sealing, a paper or plastic strip is stuck onto an actual container and onto a screwed-on or rotated cover, in order to prevent movement of a container and a cover relative to each other. Such seals nevertheless have a general disadvantage that they only connect a part of a cover and of a container to each other, such that it is possible for these to be removed and replaced without any trace of this being left. In packaging containers in which a cover member has one or more openings which can be aligned with corresponding openings in an actual container, to pour out a pourable product contained in it, unhygienic soiling of these cover openings is not prevented. A further disadvantage with curved sides is that removal of an adhesion-seal is more difficult for a user. In a case of a said second implementation of state of the art, a seal is stuck on over pour-openings. This seal can either be positioned under a screw-type or inserted cover, which acts as a mechanical closure of a packaging container concerned, or on a cover of a type mentioned above, provided with above-mentioned openings. In a first case, a buyer or user of a product can only see whether a seal has been removed or handled after unscrewing or removing a cover, and in a second case, movement of a cover is not eliminated, such that a cover concerned, if it can be removed for refilling, can actually be removed and replaced without a seal being damaged. In this case also, a customer cannot see whether a packaging container has been handled.
Therefore, there is still a need for a removable closure means, such as a seal for example, which prevents opening of a packaging container with cover openings, and which also ensures a hygienic state of cover openings, and irreversibly shows handling by a customer.
SUMMARY OF THE INVENTION
The present invention is therefore aimed at production of closure means, on a packaging container, which prevents opening of a packaging container and also functions as an indicator of intactness of a packaging container concerned, and simultaneously hygienically seals openings in a cover member of a packaging container.
This aim is achieved by production of a packaging container with a closure means in accordance with independent claim
1
. Further advantageous designs of a present invention follow from dependent claims, description and annexed diagrams.
A packaging container in accordance with a present invention is as follows:
an actual container (hereafter referred to as a ‘container’) for pourable products or goods such as spices, flours, dried fishfood, etc. A container concerned has, for example, in a main surface, its upper surface for example, one or more openings through which a pourable product can be poured.
a closure member, such as a cover for example, which is connected to an actual container and/or to a closure means, such that movement of a closure member and a container in relation to each other is prevented.
A pourable product can be removed from a packaging container concerned, by aligning openings in a container and a closure means, insofar as sealing means have been removed, whereupon, by inclining a packaging container concerned, a pourable product flows out under gravitational force.
An actual container concerned can have any appropriate form which serves application of a closure means and movement of closure means and of a container in relation to each other. A top surface, of a container concerned, with openings, can therefore be rectangular, square or quadrangular for example, hexagonal or curvilinear, oval-shaped or circular for example. In particularly favoured implementations of a present invention, a top surface of a container with openings is either circular or hexagonal. A container concerned is therefore preferably cylindrical or six-sided in form.
A container concerned can nevertheless have a top face which is different in size to an opposite face, such that a truncated cone-shape results, for example.
At least one side of a container concerned has at least one opening through which a pourable product can flow. It is nevertheless also possible to have several openings in this face. These can, for example, be of different sizes, in order to enable selection of one particular opening for pouring a very small quantity, for example. Such openings can be implemented as groups of holes, for example, such that variation of a quantity poured is possible by means of different numbers of holes or different sizes of holes poured through.
These holes can have different forms for specific purposes. It can, for example, be preferable for them to be circular or even oval, rectangular, or for them to have another form.
The number and size and form of holes can likewise be determined by a type of pourable product concerned. It can therefore happen that another form, size or number of openings proves useful for one pourable product than for another.
The container concerned can be provided with internal partitioning forming several separated container-sections. This facilitates simultaneous enclosure of different poured products in one container. In such a case, each partition must have at least one opening on a top face to enable selective extraction of a product.
In a case where several openings are disposed in a top face, a cover member of a packaging container can be moved such that in each case one of openings in a main side can be brought into alignment with an opening in a closure member. Insofar as openings are associated with different partitions, it is also possible to arrange these openings of a main surface, or to arrange an opening in a closure member such that simultaneous pouring of flowing products from more than one partition is possible, in order to mix these.
As described above, with arrangement of partitioning in a container concerned, this partitioning can be arranged such that they lie, with one side, on a top side of a container, such that their openings all lie on this top side. It is nevertheless also possible to introduce cross-walls such that openings lie on different sides of a container. It is possible, for example, to dispose a cross-wall parallel to a top face, in order to divide a container into two container sections. In this case an opening can be provided on a top side and an opposite second side.
Therefore, there are accordingly two cover members, one on a top face and one on a base surface. A container concerned can furthermore be provided with further openings enabling it to be filled with poured products in filling machinery. These openings are preferably larger than openings for a user to pour a product concerned through, in order to speed up a filling process as much as possible. In one preferred implementation of a present invention, a base, opposite a top face, can be removed so that a container concerned is accessible for filling over its whole base surface. This base can be attached, by known measures, to a container, glued, held under tension or fused on, for example.
Immediately opposite a top face, a cover member of a packaging container concerned is applied. A cover member concerned can have a form which exactly covers a form of a covered top face, nevertheless it can also be implemented smaller, leaving a section of a top face uncovered. Whatever, it must be shaped a
