Description

Technical field

The invention relates to a device for storing and supplying bulk (bulk) goods sold by weight. The invention may find application, for example, in stores when selling by weight of bulk goods. However, it is applicable in other situations related to the handling of bulk goods sold by weight.

State of the art

In the sale of bulk goods (including consumer goods), sold by weight (sometimes called "bulk goods"), such as sweets, tea, cereals, nuts, etc., various systems are used for storage and provision the availability of goods to consumers. These systems often contain one or more containers for storing goods. The containers are placed in the store so that customers can transfer the right amount of goods from the container to the package or similar container available (available) to the buyer. Then the buyer can take this package to the counter in the store for weighing and paying for the goods.

If the store offers several varieties of a certain product, then usually containers, each of which contains one of these varieties, are installed next to each other, often in the form of a matrix formed by horizontal rows and vertical columns of containers. In this case, the buyer can simply select or pour the desired amount of each variety of goods and put everything in a common package to get a mixture of these varieties. This type of sales by weight of bulk goods allows the store manager to effectively use the space, reduce the cost of packaging and provide the buyer with the opportunity to purchase the desired amount of a mixture of varieties of goods. With the appropriate configuration of the containers, it is also possible to demonstrate the goods in a visual and attractive way, providing the buyer with high-quality information and, in addition, contributing to the growth of sales.

The systems used can be divided into two main groups: open systems and closed systems. When using open systems, customers can access the goods stored inside the corresponding container in the form of direct contact with them. Usually, in this case, the buyer uses a spoon or scoop to transfer the goods from the container to the bag or other container. In closed systems, direct contact is excluded because they are designed in such a way that the goods can be dispensed without giving the buyer the opportunity to touch him before the goods leave the container in which he was contained.

Known open systems for the sale of bulk goods often contain a container for the goods, equipped with a front, custom opening, to which the buyer has easy access. As a rule, a spoon or a scoop is located near the container, so that the buyer can select the desired amount of goods without touching it with his fingers. A loading opening may be provided at the rear of the container to reduce the risk of foreign objects and particles, such as dust and debris, entering the container. Both openings are usually equipped with hinged covers that can be in the open or close position. To facilitate access to the goods through the user hole, the bottom wall of the container can be made inclined in the direction of this hole. When a certain quantity of goods is selected and retrieved, the corresponding amount of goods remaining in the container slides into the area adjacent to the user hole, which facilitates access to the goods for the following customers. An example of an open system is described in EP 2394535 A1.

The use of such open systems is sometimes undesirable, since access to the interior of the container can be considered as creating a risk of contamination of the goods in the container.

In the case of closed systems, the risk of contamination of the goods in the container is reduced, since access to the interior of the container is prevented. EP 2294948 A1 describes a closed system containing a so-called "gravity hopper". This device comprises a housing with an internal container and with a discharge zone located beneath it, passing into the outlet channel in the form of an outlet nozzle. A working tool is attached to the housing with a possibility of rotation, which is also connected with a door located in an opening located between the internal cavity and the outlet nozzle. By manipulating the working tool, the user can open the door, so that the bulk product located in the cavity can, under the action of gravity, exit by gravity through the outlet nozzle. The issued goods may be collected in a receiving container held by the user under the outlet nozzle. Upon completion of the delivery of the desired quantity of goods, the working tool is released, and the door closes.

Such closed systems with gravity feed for storage and delivery of bulk goods have the advantage that they exclude direct contact of buyers with the goods contained in them. This reduces the risk of contamination of the goods. Therefore, closed systems are often considered more hygienic, which contributes to the growth of sales of goods to the benefit of the seller.

However, it was found that closed systems with gravity feed have serious drawbacks in relation to the issuance of certain types of goods. Some types of sweets, including sweets and marmalade, are examples of products whose issuing from closed systems creates problems. So, sweets that have a sticky surface and have a non-rigid (soft) consistency tend to stick together to form “lumps”. This often leads to the fact that the internal channels of the container, in particular its dispensing device, are clogged (blocked). It turned out, for example, that sweets having a jelly-like consistency, in particular jelly worms and jelly babies chewing marmalade and especially large jelly sweets, are very difficult to dispense when using closed systems. The longitudinal size of an individual unit of such large-sized sweets can reach or exceed 5 cm. The channels with the smallest cross-section, such as the installation zones of dampers, valves or other means for regulating the flow of goods dispensed, are most likely to block or clog. In addition, even if it is possible to dispense such sticky products, the formation of lumps makes it very difficult, if not impossible, to ensure the correct dosage of the dispensed goods.

Considerable efforts have been made in the past to solve this problem of storage and dosed delivery of sticky and soft bulk goods from closed systems. Various systems and devices have been tested, equipped with automatic dispensers of various types, including rotary and progressive valve components, worm feeders, endless conveyor belts and feed plungers. However, to date, no satisfactory solutions have been found. In US 4718578, GB 2254315 and US 4889263 described various closed systems for the dosed delivery of bulk goods. These systems use a working tool that can be manipulated on the outside of the container and which extends into the container. By operating this tool from the outside, the user can manually push the products in the container to the outlet of the container. To ensure the full functionality of the container in a closed system, all known systems are equipped with a manually controlled outlet damper. Thus, in order to complete the dosed dispensing operation from these systems, the user must individually control the working tool. This requirement to control the two components is a significant drawback, since the user must use both hands in the issuing operation. Therefore, first he has to fix the receiving tank on the container or otherwise fix it at the outlet.

Disclosure of invention

In this regard, the invention is directed to an improved device for storing and supplying bulk goods sold by weight.

The invention is also directed to the creation of a device of this type, providing the ability to store and conveniently dispense any desired quantities of goods of various types while preventing access from the outside to the goods inside the device.

The problem solved by the invention also consists in creating a device which, for dispensing any desired quantity of goods, can be easily and conveniently controlled with one hand.

Another task is to create a device that provides the ability to conveniently and accurately dispense bulk goods having a relatively sticky outer surface and a soft consistency.

An additional task is to create a device that is simple in design and reliable in operation.

Another task is to create such a device that allows you to attractively demonstrate the goods inside it.

These and other problems are solved by creating the device described in the restrictive part of claim 1 of the attached claims, while its special technical features are given in the distinctive part of claim 1.

The proposed device is intended for storage and supply of bulk goods sold by weight. It contains: a container with a loading hole and a dispensing hole; closing means to prevent access from the outside, through the dispensing opening, to the interior of the container and feeding means for removing goods from the interior of the container through the dispensing opening. The supply means comprises a hand-operated feed unit movably attached to and protruding from the outer wall of the container. In this case, the feed unit comprises a gripper located outside the container, and a working tool located inside the container and configured to move the goods to the dispensing hole while holding and manipulating the gripper with his hand. This node is made with the possibility of linear movement along the first axis and rotation at least around two mutually orthogonal axes. Closing means is attached to the feed unit, configured to open to expel goods through the dispensing opening as a result of hand manipulation of the feed unit.

Since the device contains closing means to prevent access from the outside, through the dispensing opening, to the interior of the container, the risk of contamination of the product is low. The presence of a translationally moving and rotatable feed unit allows the user to purposefully manually manipulate the feed unit, which contains a grip located outside the container and a working tool located inside the container to actively, with the application of force, move the product to the dispensing hole. A device made in this way allows the user to use their senses to consciously control the working tool of the feed unit. Thanks to this control, it becomes, for example, possible to separate the adhered units of goods (hereinafter referred to as products) from each other and push or pull a single product or a desired amount of products to the dispensing opening. Thus, the device allows the user to use their intelligence to actively manipulate the feed unit in order to separate and issue the desired quantity of goods. At the same time, the ability to store and distribute goods that were previously considered unsuitable for storage and delivery through closed systems was confirmed in practice. Examples of goods that have proven suitable for storage and dispensing by the device of the invention are sticky and soft sweets such as jelly babies chewing marmalade and larger, sticky and soft jelly worms chewing marmalade. The attachment of the closing means to the feed unit further provides automatic opening of the closing means when manipulating this unit. This greatly facilitates the issuance operation. Indeed, this operation can be completely carried out with one hand, so that the user can use his second hand when performing the dispensing operation, for example, to hold the receiving container at the dispensing opening. This can be of great importance, for example, when the user must place in front of the dispensed opening and hold a bag or other container to receive the dispensed goods.

The feed unit may be movably attached to the outer wall of the container, attached, with the possibility of rotation, at least one of the adjacent walls of the container. In this case, the closing means has an inner wall attached to the specified outer wall with the possibility of movement, together with the outer wall, between the closing position at which the dispensing opening is closed and the opening position at which the dispensing opening is open. Thanks to this embodiment, the automatic opening of the closing means is provided in a simple, cost-effective and reliable way, requiring the use of a relatively small number of moving parts.

The closure means may comprise a valve component mounted to move between a closing position in which the dispensing opening is closed and an opening position in which the dispensing opening is open. In this case, the feed unit is connected to the valve tool by means of mechanical coupling, capable of moving the valve component to the opening position when moving the tool of the feed unit in the direction of the dispensing hole. This embodiment corresponds to an alternative design that provides automatic opening in an inexpensive and reliable manner.

The mechanical connection may include a flexible wire attached to the feed unit and to the valve component. This solution results in a simple and reliable design at very low production costs.

Alternatively, the mechanical coupling comprises a linkage attached to the feed assembly and to the valve component. In this embodiment, closing of the closing means can also be provided when the working tool is retracted from the dispensing opening.

The feed unit may be rotatable around three mutually perpendicular axes, one of which is the first axis. By increasing the number of degrees of freedom in the feed unit with respect to the container, it will be easier for the user to freely manipulate the feed unit. In some applications, for effective handling, it may be sufficient to make the feed assembly movable along one axis and rotatable around two axes. However, in more complex applications, it is desirable that the feed assembly, in addition to mobility along the axis, be able to rotate around three mutually orthogonal axes.

The feed unit may comprise an elongated part, the longitudinal axis of which defines the first axis. This embodiment makes it possible in a simple, reliable and inexpensive way to ensure accurate and precision handling, involving significant movement of the working tool.

The user gets the opportunity to manipulate the feed unit in such a way as to promote individual products to the dispensing hole even without the ability to see the goods through the wall of the container. However, the active and targeted manipulation of the feed unit to effectively remove the desired quantity of goods is greatly facilitated if the user can see the goods. Therefore, it is desirable that at least a portion of the container is made transparent. Such a transparent portion preferably includes container walls that are located between the eyes of the user and the operating area of the working tool as part of the feed assembly.

In some applications, it is desirable to make essentially the entire container from a transparent material. In this option, the conditions for viewing the product and detecting any lumps formed in it are improved. In addition, this option allows you to more clearly demonstrate the goods placed in the container.

The dispensing opening may be close to the dispensing tray. With this embodiment, the feed unit can be used to actively promote the goods (pushing or pulling) directly to the dispensing tray. After that, the removal of goods from the device is provided under the action of gravity acting on the goods. This embodiment facilitates, for example, the collection of output goods, since the receiving container can be held in a position in which the dispensing tray is located inside this container.

The closure may include a one-way valve that does not impede the delivery of goods and prevents the introduction of foreign objects into the container from the outside. In this embodiment, ease of elimination is combined with the presence of an effective means to prevent, in a simple and inexpensive way, the contamination of the goods.

In this case, a one-way valve can be installed in the dispensing tray and contain a pre-loaded valve component, configured to open in the direction of delivery under the action of gravity acting on the goods falling on the valve component. The preload is applied to the valve component in the direction of its locking, so that the combination of the properties of preventing the ingress of foreign objects and the possibility of dispensing goods is achieved in a simple, reliable and cost-effective way.

Other objectives to be solved by the invention and its properties will become apparent from the following detailed description of its variants and from the attached claims.

All terms used in the claims should (unless expressly agreed otherwise) be interpreted according to their usual meanings in the technical literature. All references to a component, device, instrument, tool, operation, etc. should (unless expressly agreed otherwise) be interpreted not in a restrictive sense, but as indicating the presence of at least one component, device, tool, tool, operation, etc. Any operations described must not (unless expressly agreed otherwise) be performed in the manner described.

In figure 2, the device of figure 1 is presented in a perspective image, in the open state.

Figure 3 in a perspective image shows the feed node, which is part of the device of figures 1 and 2.

Figure 4 presents a perspective image of a system containing two devices installed side by side with one another of the type shown in figures 1 and 2, with the feed nodes removed from them.

The implementation of the invention

The invention will now be described in more detail with reference to the accompanying drawings, in which certain embodiments of the invention are presented. However, the invention can be implemented in many different forms and therefore should not be construed as limited to the presented options. On the contrary, these options are presented only as examples to make this description detailed and complete, i.e. giving professionals a clear idea of the scope of the invention. The designations used correspond to the same elements throughout the description.

The device shown in figures 1 and 2, contains a container 10 and a feeding means in the form of a node 20 supply. The walls of the container 10 together form an internal space for storing bulk goods sold by weight, such as sweets, candies, peanuts, cereals, tea, coffee, and the like. The device is especially suitable for storing and dispensing loose goods having a sticky surface, possibly in combination with a relatively soft texture, and goods that tend to stick together to form “lumps” containing a certain number of units of goods (products). Examples of such products are jelly candies, such as jelly babies and jelly worms. The container 10 has a back side and a front side with which the device should face the user. Between the rear and front walls there are mutually parallel and essentially flat side walls. Thanks to this embodiment, it is possible to install containers next to each other, as illustrated in FIG. 4 using two containers as an example. The walls forming the back, front and sides are made of a transparent polymer material. Thanks to this embodiment, a convenient and attractive presentation of the stored goods is achieved. As will be shown in detail below, the transparency of at least some parts of the container also makes it easier for the user to operate the device.

The container has an upper loading opening, which is closed by a removable lid 11 during normal use of the device. In the presented embodiment, the lid 11 consists of two parts 11a, 11b pivotally connected to one another, so that the loading opening can be accessed by turning the front part 11a of the lid 11 around the hinge axis 11c extending between the side walls of the container 10 perpendicular to them.

On the front of the container 10 there is a dispensing hole 12. It is located on the first end of the dispensing tray 13. The second end of the dispensing tray 13 is located at the front wall of the container, so that the tray communicates with the interior of the container 10. Thus, the inlet of the tray is formed in the intersection plane front wall and tray 13.

The container also has a bottom wall 16, made inclined and located between the rear of the container and the inlet of the tray. The presence of an inclined bottom wall 16 allows for the supply of goods in the direction of the inlet of the tray, which facilitates the movement of goods under the influence of gravity (gravity feed), and also contributes to the implementation of the principle of "first-come-first-sold" to products in the container.

The container also includes closing means 30 to prevent outside access to the interior of the container 10 through the dispensing hole 12. The closing means 30 includes a shutter 31 defining the outer wall of the container and pivotally connected to the rest of the container 10. The shutter 31 has an upper wall 32, front the (inner) wall 33 and two side walls 34. The front wall 33 and the side walls 34 of the shutter are inserted in a tight fit into the corresponding rectangular opening 14 of the container 10. The dimensions of the upper wall 32 are wound such that when the flap 31 is in the closing position shown in Figure 1, it covers the entire opening 14. At each end of the back edge of the upper wall 32 of the damper 31 is fixed a pivot pin 35, oriented in the transverse direction. Each hinge pin 35 is inserted into a corresponding finger slot 15 secured to the edge of the container opening 14 so that the shutter 31 can rotate relative to the rest of the container 10 between the closing position shown in FIG. 1 and the opening position shown in FIG. 2 .

In the closing position, the upper wall 32 completely covers the opening of the container 14, so that access to the interior of the container through the opening 14 is not possible. In addition, in the closing position, the front wall 33 of the shutter closes the inlet of the tray. Thus, the front wall 33 prevents the exit of the goods from the container through the tray 13, as well as the ingress of foreign objects into the interior of the container 10 through the dispensing hole 12 and the tray 13.

When the shutter 31 is rotated to the opening position shown in FIG. 2, the upper wall 32, the front wall 33 and the side walls 34 of the shutter 31 still block access to the interior of the container 10 through the opening 14. However, in the open position, the front wall 33 of the shutter 31 diverted from the inlet of the tray, so that the goods can approach the inlet from the interior of the container. From this hole, the goods can be fed under the action of gravity along the tray 13 and through the dispensing hole 12.

As shown most clearly in FIG. 3, the feed unit 20 includes parts such as a gripper 21 and a working tool 22. In the illustrated embodiment, the feed unit also contains an elongated part in the form of a cylindrical rod 23, to the ends of which a gripper 21 and a working tool 22 are attached. To facilitate the installation of the feed unit on the container, the gripper 21 and / or the working tool 22 can be mounted on the shaft 23 in a removable manner. In the illustrated embodiment, the working tool 22 is essentially in the form of a scapula or scoop. A stop in the form of an elastic washer 25 is mounted on the rod 23 along a sliding fit.

As shown in FIGS. 1 and 2, the feed assembly 20 is fixedly attached to the container 10. In the presented embodiment, the rod 23 of the supply unit 20 is inserted into the through circular hole 36 made in the upper wall 32 of the shutter 31. The supply unit 20 is installed so that the gripper 21 is located outside the upper wall 32, and the washer 25 and the working tool 22 are on the other side the upper wall 32 and the round hole 36. The diameter of the round hole 36 slightly exceeds the outer diameter of the rod 36, so that the rod 23 and the feed unit as a whole can move relative to the shutter 31 and the rest of the container 10. The movement of the feed unit 20 is limited by COROLLARY washer 25, the tool 22 and the grip 21, since the dimensions of these components exceed the diameter of the circular hole 36. This arrangement guarantees mobility with respect to feed unit 20 of the top wall 32 and flap 31 of the container 10.

More specifically, the supply unit 20 is attached to the container 10 with the possibility of linear movement along the axis of the rod 23 and rotation about this axis of the rod 23 and two other axes orthogonal to one another and the longitudinal axis of the rod 23.

Next will be described in detail the operation and use of the device. The damper 31 is in the initial state in the closing position shown in FIG. In this position, the product can be loaded into the container 10 through the loading hole by folding the front part 11a of the lid 11 for this purpose. The goods loaded into the container 10 can be stored in it, and buyers can see it through the transparent walls. The inclination of the bottom wall 16 ensures that the goods under gravity are fed to the dispensing tray 13, so that there are always products ready for dispensing near the dispensing tray 13. Since the front wall 33 of the shutter closes the inlet of the tray, the goods cannot exit the container 10.

When the user wants to remove a certain quantity of goods from the container, he places a bag or similar container at the dispensing opening 12 of the tray 13. To minimize the risk of spilling goods, the outer dimensions of the tray can be selected so that the dispensing opening 12 can fit inside the receiving container intended for use together with the device.

The user then grasps the gripper 21 of the feed assembly 20 to control this assembly with one hand. When controlling the feed unit 20, a working tool 22 is used to separate the desired quantity (desired portion) of products from the mass of goods stored in the container. In the presented embodiment, such control is facilitated by the fact that the user can see the goods through the transparent walls of the container. It was, however, found that the desired quantity of goods can be separated from the mass of the goods and blindly. This is because the user is able to assess the condition of bulk goods and the degree of adhesion of units of goods based on the "feeling" of the goods through the feed node. Therefore, even in the case of opaque containers, the user can manipulate the feed unit in a directional manner to separate a predetermined quantity of goods from the mass of bulk goods in the container.

After that, the user manipulates the feed unit 20 so as to move, for example, push or pull, the desired amount of goods to the inlet of the tray. This movement of the feed unit 20 is accompanied by an increase in the angle between the rod 23 and the upper wall 32, as can be seen from FIG. 2. The rod 23 will in this case contact and interact with the edge of the circular hole 36 in the upper wall 32 of the shutter, which will lead to a pivotal rotation of the shutter 31 with its transition to the open position. However, it should be noted that the shutter 31 can be moved to the opening position by many other options for moving the feed unit 20, and also, if necessary, simply by grabbing and lifting the upper wall 32 of the shutter 31.

After the shutter 31 has reached the opening position, and the desired quantity of goods has been brought via the feed unit 20 to the inlet of the tray, this quantity of goods will pass through the tray and through the dispensing hole 12 into the receiving container.

Obviously, the dispensing operation can be repeated until the desired quantity of goods is in the receiving container. When the user releases the feed assembly 20, the shutter 31 will rotate in the opposite direction under the action of gravity, i.e. will return to the closing position shown in figure 1.

Thus, the device according to the invention provides a convenient and reliable means for storing in a closed container and for issuing from it the desired amount of bulk goods, even if the goods are products that are sticky and soft or otherwise making it difficult to dispense from known closed systems .

Figure 4 shows how it is possible to install two devices according to the invention next to one another for forming a system. In Fig. 4, the dispensing units are not shown, i.e. only containers 10, 10 'are shown. The dispensing trays 13, 13 'of the two containers 10, 10' have slightly different shapes that are designed for different types of goods and for various types of receiving containers.

The invention has been described above with examples of some of its variants. However, as will be appreciated by those skilled in the art, other variations from those described are included in the scope of the invention defined by the appended claims.

For example, the feed assembly may be movably attached to the container in various ways. So, in an alternative example, the outer wall of the container is provided with a socket in which the movable ball is held. A rectangular hole is made in the ball, into which a part of the cylindrical rod, which is part of the feed assembly, is inserted. This embodiment allows you to move the feed node in the axial direction and rotate it relative to the ball. In this case, the ball, together with the feed unit inserted into it, can rotate relative to the outer wall of the container around two orthogonal axes.

Instead of making the closing means in the form of a shutter having an outer wall to which the feed unit is movably attached, the closing means may be connected to the feed unit in other ways. Thus, the closing means may include a valve component mounted near the dispensing opening with the possibility of rotation between the closing and opening positions. For automatic opening of the valve component during the manipulation of the feed unit in order to remove the goods, the feed unit can be mechanically connected to the valve component, for example, by means of a flexible wire or a lever mechanism. The closure means may also be provided with a one-way valve installed in the dispenser tray below the damper or valve component. A one-way valve may comprise a preloaded valve component that is normally closed and that opens in the dispensing direction under the action of gravity acting on products fed to or dropped onto the valve component.

The device may also contain additional means to prevent foreign objects from entering the container. For this purpose, the tray can, for example, be given dimensions that make it impossible to insert human fingers or hands into the container. Alternatively or additionally, needles or similar parts may be installed in the tray or in another dispensing channel, creating a risk of damage to part of the body when attempting to enter the container.
