Description

Portioning device for a container.

Technical Field of the Invention

The invention relates to a package according with the preamble of claim 1.

State of the art

A state of the art is known from series of devices, which allow the transfer of solid substances susceptible to bleed. Thus, for example, the US document 5,692,868 shows a device that can be hung with a bag deformable reserve, at whose then lower end is provided a transfer device. After the opening of the output, this device allows, through the deformation of the reserve bag, a faster total transfer, that is, an emptying of the solid substance susceptible to sliding down.

It is known from US 6,834,995 a portioning device, in which this device assignment includes cords, in which through traction on These cords will control the opening of the lower outlet. He chamber content can then fall without exact dosage directly from the camera.

The mechanical properties of the device according to US 6,834,995 make the use convenient for the described emptying of containers with deformable chamber, in the that you can download volumetric contents of several liters totally or without exact measurement. Such containers do not adapt to a final consumer and are planned, for example, rather to feed containers, detergents or other products susceptible to shift, etc. In smaller packages, since there, despite of the size of the containers, it should be possible to perform dosages, for example, in the range of grams. To that end, The devices mentioned at the beginning are not practical.

It is known from the document US-A-3 179 301 a container with a portioning installation of the type mentioned to beginning.

The document US-A-5 307 955 publishes a container with a chamber with flexible material chamber walls, which form a support surface. A portioning facility that can be closed automatically is integrated within the areas bounded by the support surface in the container.

Summary of the Invention

Starting from this state of the art, the invention has the task of making the installation of portioning of a container of the type mentioned at the beginning for usual types of household products and especially for containers that form a deformable chamber.

This task is solved, according to the invention, with the features of claim 1.

The container has a chamber intended for housing of a product susceptible to bleed. This camera it can be closed by means of a portioning device adjacent to this camera, in which with the splitting device in portions in an open position can be set up, at least in part, a step in the lower end of the camera. The Portioning installation features two hatches of valve, which are connected to each other by means of at least one spring element, so that the closing edges of the valve flaps in the rest position of the spring elements, keep the camera closed against the medium ambient. In this way, through pressure on the flaps a valve hole can be achieved in a simple way more or less large step and, therefore, a simple dosage of products susceptible to bleed.

The device acts as a double device rocker for content output only when you are valve flaps remain pressed while get an automatic closing when the trap doors are released valve.

With a corresponding device you can manufacture bags for products in the mentioned quantities of several kilograms of weight that, despite everything, can be easily handled by the buyer.

Finally, these features allow the realization of an element of integrity guarantee through the simple extension of a edge of the material that forms the chamber, which closes by the exit of the division facility in portions.

The device, which can be placed in the opening of a container, for the transfer in portions of a content dispersible, it can be integrated in the sense that it is considered by the user as a single piece with the container.

Other advantageous embodiments are characterized in the dependent claims.

Detailed description of embodiments

Figure 1 shows a side view schematic, partially in section, of a lower section of a container 1 with a portioning device 2. The section upper can be configured as in the representation of the Figure 2. With the reference sign 3 a device of support and suspension, in which a bag 4 is fixed that It forms a camera. The suspension device 3 may contain also a bag closure (upper). The bag can be rigid, semi-rigid or flexible. It can be constituted as a sack, bag, fiber material, plastic sheet or of other materials; in a more advantageous way, the bag is flexible at least in its lower zone. It can be transparent or opaque Fields of application are animal feed, detergents and / or building materials. Such bags are offered in the retail with frequent on freight platforms, of so that the material of the bag is exposed to some external influences This also applies to the installation of split into portions 2. A possibility is described below. how this portioning facility can be protected 2, in connection with figures 3 and 5.

The material of the chamber 4 forms a box of cardboard or bag based on fiber or plastic material. The chamber 4 may be configured, for example, in the form of a sack, of so that the portioning installation 2 forms a Bag closure originally opened on both sides. The chamber 4 is then formed from two side plates rectangular, which close on the sides through the insert of an intermediate piece or directly. In the case of using plastic sheets, you can find also use a sheet Endless cylindrical bag. In the suspension device, the Rectangular sheets can be assembled again and welded, staple or close otherwise.

Portion 2 installation is constituted in the simplest case of the embodiment example represented here, when the bag is higher perpendicular to the drawing of the drawing in figure 1, which will be the general case, for two rigid, flat rectangular valve flaps 11 and 12, angular or in the form of a primitive circle, which are connected elastically with the help of at least one spring element 10. In this case, the position represented in Figure 1 is the position at rest, that is, the closing edges 16 on the side of the camera close the bag in front of the environment. Other words, the previous tension of the spring element 10 presses the closing edges 16 of the chamber side of the two hatches of valve 11 and 12 one above the other and separates the edges 15 from the side from the environment one out of the other. In a more advantageous way, along the longitudinal direction (i.e. perpendicular to the plane of the drawing in figure 1) are several provided, for example three spring elements 10 of this type, to maintain a uniform pressure and prior tension on The entire width of the bag. As spring elements 10 can be use, for example, springs, as they find application in called clothes pegs for sale in commerce, in which, so therefore, free ends of a wire pass over several turns to another free end, which is then embedded under previous tension corresponding on valve flaps 11 and 12. The elements of spring 10 are then, therefore, compression springs that They allow a twist around its main axis.

Valve flaps 11 and 12 do not have to extend over the entire width of the chambers 4; they can also form, for example, half or 2/3 of the lower end area or they can be placed on the corner.

Figure 2 now shows a side view schematic partially in section of the upper section e bottom of a container 1 with a split installation in portions 2 according to figure 1, in which the susceptible product 24 of flow flows from the exit hole. The same signs of reference designate in all the figures the same similar characteristics or characteristics. To this end, the user exerts, for example, with one hand pressure on the hatches of valve 11 and 12 according to arrows 31 and 32 represented opposite each other. The pressure must be carried out in the area of the free bottom edges 15, in any case below spring elements 10. Then the valve flaps 11 and 12 they fold around an axis provided through the or spring elements 10, perpendicular to the drawing plane of Figures 1 and 2 and the closing edges 16 are removed from the side of the chamber of each other and the songs on the side of the environment are move one over the other. The discharge hole 14 is maximum when the two valve flaps 11 and 12 are parallel between Yes, as depicted in Figure 2.

Pressure can be exerted from outside through of the sheet of the chambers 4, in a more advantageous way exerts pressure there on a corresponding mark. In this way, the discharge product 24 comes into contact with the hatches of valve 11 and 12. These may be constituted, for example, of Stable plastic, metal, wood or corrugated cardboard. The elements of spring 10, made of metal for example, may be wrapped also with plastic sheet, when the discharge product does not must come into contact with the elements of spring 10.

When the expected amount of material 24 susceptible to creep, the pressure of according to arrows 31 and 32, so that the elements of spring 10 again move the closing edges 16 on the side of the camera over each other until they close again totally the camera. In this case, they may be provided flexible and hermetic separators (not shown here) in these closing edges 16. It is also possible that closing edges 16 have combs that mesh with each other, which during gearing, or press successive material that can be shifted present in this area of return to the camera or let it out still. Through the controllable size of the outlet hole 14 and the automatic closing function of the split installation in portions 2, a simple and sufficient dosage is possible Exact for these application purposes.

In the area of the division facility in Portions 2 glue the bottom edges of the sheets to the less partially with the wall of the chamber 4.

The container 1 is represented in figures 3 and 5 in an upright position This way it can be offered in the Commerce. The container 1 is then placed, as can be deduced from figure 3, on two zones 5 of the chamber 4 filled with material, which are separate from the splitting facility in 2 triangular portions in the section. According to figure 3, the lower sections of the sheets protrude, against Figures 1, 2 and 4, beyond the installation of division in portions 2. According to the invention, then a integrity guarantee element provided with the sign of reference 21. This is present as a flat double sheet, that is, which consists of the two sheets of the two sections bottom of said side sheets, which are connected between yes at least in corresponding adhesive zones 23, for example a through gluing. In this way, in addition to the closing of the chamber 4 through the complete fence of the division facility in portions, it is also possible to remove the integrity guarantee element 21. It can be easily cut perpendicular to the drawing plane. Then the previous tension of the spring elements 10 will close the chamber on the edges 16 and the container can take a position, as shown in the Figure 1.

Instead of continuing to pull the blade existing camera material, you can also drive areas  flat walls of the chamber as such protruding more beyond the bottom side of the valve flaps 11, 12 and it can join together, to configure a guarantee element of integrity 21. Instead of adherent sheets with each other and that they can cut, breakable ribs are also conceivable.

Figures 1, 2 and 4 show by way of example the so-called stable bags, which can be hung over the head for portioning into devices on its side stable.

Instead of the advantageous inclusion of the installation of portioning 2 through the bag of chamber 4 for protection against damage, as shown in the Figures 1 to 3, the installation of division into portions 2 can be arranged, in principle, also outside the chamber 4. Figure 4 shows a partially schematic side view in section of a container of this type with a division installation in portions. Here the closing edges 16 are provided in the environmental side and free edges 15 are arranged in The side of the camera. Here you can apply the forces on the valve flaps 11 and 12 above the elements of spring. The initial forces will be directed in this case in the direction of arrows 31 and 32, so that the direction of the torque to be applied rotates then aligning the arrows, to get valve flaps 11 and 12 parallel, so that material 24 may come out in a manner similar to that shown in the Figure 2. In this exemplary embodiment, however, when the portioning device 2 is closed, the weight of the product 24 susceptible to sliding presses on the areas of the closing edges 16 of the valve flaps 11 and 12, in opposition to the example of embodiment of figures 1 and 2, where the portioning device 2 closes automatically. He reference sign 16 has been here as in figures 1 to 3 for closing songs, although these are arranged here in opposition to the mentioned figure, on the outside in relation to the container. The same applies to singing 15. But the installation of division in portions it can be protected according to another example of realization by means of zones, that is, it can be arranged countersunk, as depicted in figure 3.

Finally, Figure 5 shows another example of embodiment of the invention, in which the splitting installation in portions 2 with the valve flaps 11 and 12 is arranged as in figures 1 or 3. The difference lies in the configuration of integrity guarantee element 41. This is configured here as a flat sheet, which extends around the areas of the support surface 5 of the bag and is connected there with the removable bag. In this way, the installation of Portion 2 is kept inside the container in the resting position and in this way it can hardly be damaged only from the outside.

The valve flaps 11 and 12 and the integrity guarantee elements 21, 41 may be constituted  also for materials other than those indicated, for example The latter may be another wrap around the package. He Technician knows other embodiments.

In another embodiment shown in Figure 6, during the housing, the installation of division in Portions 2 does not form the bottom closure, but the container is on the section, in which the device is provided suspension 3. The suspension device 3 can also be a clamp of the material that is formed the bag, especially it can be constituted by an outstanding dejected section of One of the side plates. Then the installation of division in Portions 2 is placed up. It is also possible a lateral housing on the large surface side plates mentioned, so that the portioning installation 2 and the suspension device 3 protrude laterally from A pile of such containers.

Figure 6 also shows an installation of division into portions that yields a dose in each case. This is achieved because valve flaps 11 and 12 present in their free edge directed in a trapdoor projection 26 approximately L-shaped, which ends in a closing edge of 16 'dosage.

The closure of the container according to figure 6 with the integrity guarantee element 21 is solved as in the exemplary embodiment according to figure 3.

The representation of figure 6 shows the stable bag in its resting position, for example as offered for sale. After the opening of the guarantee element of integrity 21 and after the rotation and suspension of the container, close it securely through the closing flaps 16. These closing flaps 16 are not here any extensions aligned with the surfaces of the valve flaps 11 or 12, but are sections folded over each other. This way, the valve flap surfaces 11 or 12 are already further away from each other in the closed position. When applied a force for activation according to arrows 31 and 32, the closing edges move away from each other and the edges of dosage closure 16 'move towards each other until They close by contact. A technician can clearly recognize that material 24 susceptible to sliding from the container is dosed in an amount that essentially results through volume 27, that is, volume 27, which is formed by the polygon, which is delimited in the cross section by the surfaces of the valve flaps 11 and 12 and for a virtual surface of closure between the 16 'dosage closing edges. When release the valve flaps 11 and 12, they return from back to the starting position of figure 6 and the edges of closure close again the stable bag suspended by the head.

This dosage volume 27 may be also formed, in other embodiments, because either only the closing edges 16 and / or the closing edges dosing 16 'are aligned with each other in front of the valve flaps 11 and 12, so as to surround said volume dosing 27.

In other embodiments, the packages 1 they can also be divided in length and can contain different products, which can be extracted separately dosed through series of two valve flaps 11, 12 arranged one behind the other in the longitudinal direction of the valve flaps 11, 12.

The invention may also comprise examples. of realization, in which the installation of division into portions It is subsequently placed in a container. With other words, the portioning installation can be an element separated, which presents, for example, in the cross section only the shape of figure 1 without bag chamber 4. Then an exit hole can be cut, for example, in the container the one that inserts the installation of division into portions 2 separated with valve flaps 11 and 12. The zones designated in figures 1, 3 and 4 with the reference sign 22 is they can then glue on the valve flaps 11 and 12, for example with the help of an adhesive layer applied on the inside the bag, which is protected by means of a sheet of protection against material 24 susceptible to creep, and whose protective foil is then removed for insertion of the separate portioning installation 2. Extreme areas of the container can also be folded around the edges 15 of the valve flaps 11 and 12 and can then be retained, for example, by means of a flexible tape, which is placed around the lower area of the valve flaps 11 and 12, by means of retention teeth provided inwards on the surface of the valve flaps (which are pressed in the package) and / or through other elements known by the technically, so that the bottom of the bag container extends with shutter effect around a clamping installation corresponding portioning installation. The insertion of a portioning installation 2 separate from This type can be done in a particularly simple way, Naturally, by the user in a stable bag.

Obviously, it is understood that all essential characteristics of all embodiments are can combine with all corresponding features of other embodiments, especially, therefore, also the dosing system according to figure 6 with any container configuration according to figures 1 to 5 or the fixing installation not shown in the drawings for a separate portioning facility.
