Definitions

  • This invention relates to a dosing container for the discharge of pasty or viscous product by manual pressure on the container.
  • Containers of this nature are also known as tubes which can be emptied by pressing on the outside.
  • Appropriate tubes are normally used for toothpaste, tomato purée, mayonnaise, mustard and similar products.
  • Generic tubes may consist of a metal foil.
  • Toothpaste tubes are also known which are made from a film material which is initially circumferentially formed as a tube and the tube is closed off by welding at the end remote from the discharge opening. At the oppositely situated end a container head is provided, forming the removal opening.
  • tubular containers of the generic type one of the problems is obtaining the most complete discharge of the tube possible.
  • tubes of plastic material there is also the problem that although the content can be discharged by pressing against the external surface of the tube, release inevitably leads to the return of the tube to its original shape and therefore to air being drawn into the tube.
  • the dosing container should have a characteristic of this nature in particular if exact dosing of the contents of the container is desired.
  • the object of the invention is to provide a dosing container which is as adaptable as possible with regard to the problems described above.
  • the invention assumes a dosing container as is known for example from DE-A-24 60 440.
  • This state of the art discloses a dosing container comprising two side walls which are arranged substantially parallel to each other and which are connected and spaced to each other by two face-side walls.
  • the face-side walls have at least one side fold through which the face-side walls are divided into at least two face-side wall segments which can be laid against each other and/or against the inside of the side walls.
  • the side walls are joined together and abut each other at an end remote from the removal opening.
  • the face-side wall segments project inwards.
  • a removal opening is provided on a container head extending substantially at right angles with respect to the side walls.
  • the prior-art dosing container can be emptied as far as possible due to its container shape, because with increasing emptying the face wall segments can be laid next to one another or inside on the oppositely situated side walls, which leads to the dosing container being capable of being almost fully emptied.
  • the prior-art dosing container however has no restoring properties which prevent air from being drawn in nor does it promote precise dosing when product is discharged from the dosing container.
  • the present invention provides a remedy in that it suggests that the dosing container is formed from a film material which is joined to a shoulder element.
  • the shoulder element surrounds the removal opening and creates predefined functional surfaces on the otherwise flatly formed film material, which normally at the most has been formed by folding and welding (longitudinal welded seam) the layers against one another to form an accommodating tube.
  • the film material can be closed off at one end by welding (transverse welded seam).
  • the shoulder element is normally located which surrounds the removal opening.
  • the shoulder element can form a container head which extends substantially at right angles to the side walls and forms a removal opening which is of small cross-section compared to the container cross-section at this end.
  • the shoulder element can also have functional surfaces for attaching a cap or an applicator at the approximate height of the film material, i.e. in the region of the external circumference of the formed film material.
  • Functional surfaces of this nature can be formed, for example, by a contour provided on the external circumferential surface of the shoulder element and against which a container head, an applicator or a container cover is secured.
  • the joint can, for example, be made by bonding a cap or applicator to the external contour.
  • the shoulder element is formed by means of injection moulding, very complicated modules can be formed with it and then joined to the film material. In this way a container meeting individual requirements can be relatively economically manufactured.
  • the major part of the container i.e. in particular the container volume, is here made available using the relatively economical film material, whereas only the shoulder element is formed by means of injection moulding from high quality plastic, which is in any case however, thick-walled compared to the film material.
  • a plastic film is in particular a film with a thickness of less than 1 mm, preferably less than 0.1 mm.
  • a co-extruded film with various layers is used.
  • the film normally consists exclusively of polyolefins such as PE, PP, PVC or PS.
  • this shoulder element In the embodiment of this shoulder element together with the container head, due to its geometrical embodiment, a certain restoration capability can be imparted to the film material which initially exhibits no predetermined elasticity.
  • the film material of the dosing container can be formed elastically in a predetermined manner when the shoulder element is moulded on. It is possible to preform the film material when the shoulder element is attached such that the side walls contact one another centrally and the face wall segments abut one another or at the edge on the internal surface of the side walls.
  • a tendency is impressed on the film material to deform inwards when the dosing container is increasingly emptied.
  • the film material can therefore promote a discharge of product out of the dosing container, but, after discharge of material from the dosing container, it can in all cases prevent this elastic restoration and the drawing in of air.
  • the film material can be held in a bloated state on attaching the shoulder element.
  • this bloated, i.e. relatively large volumetric, orientation of the film material is predefined.
  • the dosing container has a tendency to form a relatively large internal volume.
  • This dosing container according to the invention has two oppositely situated side walls which often form the main side walls of the dosing container and converge slightly and in fact from the end with the removal opening to the opposite end.
  • the side walls come together at this end.
  • an appropriately embodied container can have a wedge-shaped form.
  • an essentially rectangular embodiment is also conceivable, whereby the side walls are formed to converge on one another only in the rear end section at the closure side of the dosing container.
  • the container according to the invention also has face-side walls which join together the oppositely situated side walls.
  • These face-side walls are divided into at least two face-side wall segments, between which a side fold is located and which can be laid against each other and/or the inner side of the side walls.
  • the particular embodiment of the two face-side wall segments accordingly leads to the possibility of the dosing container folding up like a bellows in the region of the face sides.
  • the face-side wall segments initially approach one another.
  • the face-side wall segments With the embodiment normally realised in which the face-side wall segments are pressed inwards and the side fold is located within an envelope area which envelopes the circumference of the dosing container in a transverse cross-section, the face-side wall segments approach one another with their outer surface with increased emptying of the dosing container, whereas the inner surfaces of the respective face-side wall segments move increasingly towards the inner surfaces of the side walls.
  • This approach can be supported by suitable tensing of the material forming the container so that the dosing container has a tendency to reduce its volume automatically due to the adjacently located face-side wall segments.
  • the container With increasing emptying of the dosing container the container is folded up in the region of its face-side walls by means of which the inner surfaces of the side walls abut one another and the filling volume reduces continuously.
  • This restoration movement into a folded up state can also be promoted by suitable shaping of the face-side wall segments and on the joining lines between these segments and the side walls so that the dosing container closes increasingly from the rear closed end in the direction of the removal opening due to folding up.
  • the dosing container according to the invention is mainly formed from a film material and preferably exclusively from plastic.
  • This film material can for example be manufactured by injection moulding, blow-moulding or preferably by longitudinal welding and folding of a fed film web.
  • the film material can be formed multi-layered for forming barrier layers, in particular for the case in which foodstuffs are to be accommodated in the dosing container.
  • the barrier layers prevent the ingress of oxygen and/or UV radiation into the container.
  • the film material and the shoulder element can be joined by means of moulding on, welding or adhesive bonding.
  • stiffening ribs are formed on the side walls. These stiffening ribs are formed such that they improve the restoration of the container to the original state, i.e. the state which an unfilled container would assume with the removal opening open.
  • the stiffening ribs are preferably formed in the longitudinal direction and on the outer side of the container. It has proven expedient to provide two stiffening ribs on each side wall and in fact at the edge. Therefore, appropriate stiffening ribs are preferably formed in the region of each edge extending in the longitudinal direction of the dosing container.
  • the stiffening ribs as such can also be essential to the invention, i.e. characterising the invention together with the pre-characterising features.
  • the stiffening ribs can be joined to the film material by means of injection moulding or by means of welding.
  • the stiffening ribs and the shoulder element are formed on the film material in the same working step.
  • the stiffening ribs are allowed to open out at their ends remote from the removal opening into a container reinforcement which extends transversely to the longitudinal direction of the container.
  • a cover which is formed in one part with the shoulder element and connected to it by a film hinge, is provided to close the container head.
  • This aspect as such may be essential to the invention.
  • the stated solution is characterised apart from the prior art in that the cover is provided in one part with the shoulder element which in turn is joined in one piece to the film material of the container by overmoulding or welding.
  • the container is formed together with the container head in the course of injection moulding.
  • a second component is fitted which forms the cover and a pivotable cover base which is joined to the cover and can be connected to the container head.
  • stiffening grip elements reinforcing the film material are formed on both side walls at the container head end. These grip elements extend for example over approx. 5 to 25% of the longitudinal extension of the film material and are normally formed when injection moulding the shoulder element.
  • the grip elements are normally joined to the film material on the side walls. Normally the joint is made over the full area so that the movement of the grip elements is directly transferred to the film material.
  • the grip elements are particularly preferably supported pivotable about a pivot axis which runs parallel to a joining edge of the side wall and container head. The grip elements can accordingly be pivoted essentially in the region of the front edge of the container head.
  • the grip elements not only provide stiffening of the film material, but rather impart a certain tendency for the film material to return to its original shape.
  • the grip elements can act on the film material such that the dosing container is restored to a large initial volume.
  • the grip elements can promote automatic collapsing of the dosing container.
  • the present invention offers the possibility of forming initially functional elements of the container or functional elements which can be provided for use with the container or its content as part of the injection moulded shoulder element.
  • Such functional elements can just as well be plugged onto a unit at the end consisting of the shoulder element and film material which for example also comprises the container cap.
  • plugging on or welding on the further functional elements there is the possibility of plugging on or welding on the further functional elements.
  • consideration is especially given to a joint by means of a predetermined breaking point which is designed such that a functional element, which is provided for use with the container content, can be released by manual shearing off.
  • the grip elements are formed continuing as a contour of the cover in the longitudinal direction of the dosing container. In the longitudinal direction of the dosing container there is accordingly no discontinuity between the grip elements and the cover.
  • the cover also has on its side walls, which are formed corresponding to the side walls of the container, elevations, the contour of which is continued by the grip elements.
  • the grip elements preferably protrude beyond a contact base, formed by the shoulder element, for the cover.
  • This contact base interacts with the front of the cover on the container side.
  • the elevations on the cover are formed inwardly offset in relation to the cover, so that the part of the grip elements protruding beyond the contact base protrudes beyond the phase boundary between the shoulder element and the cover whilst transferring directly into the elevation.
  • the thickened material of the grip elements preferably continues on the container head, stiffening it, in a radial extension in relation to the inside of the container.
  • the grip elements can be joined to the side walls.
  • the stiffening effect can however already be achieved if the grip elements are only assigned to the side walls without being directly joined to them.
  • the stiffening effect of the grip elements then occurs when a user presses against externally located grip elements from the outside.
  • the grip elements are formed separately from the film material, this offers the possibility of enabling the grip elements to separately pivot back into their initial position when released without the tube in the region of the grip elements also being simultaneously extended and optionally drawing oxygen into the tube.
  • the grip elements are preferably provided with a surface designed to improve the surface feel.
  • the design of the surface to improve the surface feel may include groove-shaped elevations, dimples or other surface profiles.
  • the size of the side wall segments may vary depending on the purpose and the definitive dimensioning of the dosing container.
  • the side wall segments may each have about half the width of the side wall so that the side folds touch or almost touch in the inside of the dosing container when it is empty.
  • the filled container which has not yet been emptied has essentially a square cross-sectional area. If rectangular cross-sectional areas are required, with the container completely empty the side folds are normally situated inside, but spaced to one another.

  • the side wall segments 11 , 12 are orientated inwards and are therefore located outside of the envelope surface. Accordingly, the dosing containers 1 can be stored relatively compact adjacent to one another and vertically upright and offered for sale in cardboard packaging.
  • the cap 17 forms a standing base for the upright dosing containers 1 .
  • the material forming the container can be cardboard, composite material, laminate or film, in particular plastic film. With composite material a material is preferentially preferred, the inner layer of which is formed from a plastic film. In this way the inner surfaces of the material forming the dosing container 1 can be welded together.
  • the material should preferably have at least one plastic or cardboard layer which lends a certain inherent stability to the container. Special restoring action can be imparted to the plastic material so that the dosing container automatically folds up as it is increasingly emptied. In any event the contouring should be such that the container shows no restoration after removal of product from the container 1 , which would draw air into the container. The inherent stability is thus selected such that the container exhibits no corresponding restoration with the removal opening open and the side walls 2 released.
  • FIG. 24 illustrates a relatively simply arranged embodiment of a dosing container 1 according to the invention.
  • the main part of the container 1 is produced from folded film material 25 formed to a tube by a longitudinal welded seam and welded at one end.
  • the film material 25 has a welded lug 10 at one end.
  • a shoulder element in the form of a shoulder ring 43 .
  • This shoulder ring 43 is adhesively bonded to the inner circumferential surface of the film material and has a base area essentially corresponding to the base area of the previously described container head 4 , so that the folded film material can be connected to the shoulder ring 43 in the same manner as has been described with reference to the previous embodiments.
  • the shoulder ring 43 has a slightly conical, inwardly sloping mounting section 44 to which the film material 25 is connected on one end. At the oppositely situated end the mounting section 44 has in each case a nozzle 45 contoured to the external circumferential surface protruding over it.
  • the contouring on the external circumferential surface of the nozzle 45 corresponds here essentially to the inner circumferential surface of the supporting ring 46 of an injection moulded end cap 47 .
  • the end cap 47 only represents one example of an end closure of the dosing container 1 .
  • injection moulded elements can be mounted on the nozzle 45 . In this respect the mounting is preferably realised by bonding onto the closing element.
