Description

Field of technology

The invention relates to devices that are installed on packages for unloading the contents of the package.

Prior Art

The prior art knows a large number of packages made of flexible materials, such as boxes, bags for storing bulk granular or powdery products, in particular tea, coffee, cereals, etc. Such packages may contain a device for unloading the contents of the package. They are described in patents US 1847028 A, US 2064029 A, US 2593778 A, uS 2946496 A, US 3426955 A, etc.

So in patent US 2,069,281, publ. 02/02/1937, class. B65D 33/36 discloses a device for unloading the contents of a package, which is attached to the package, namely, above the hole located on its top flap. In the middle part of the top flap, lines of weakened strength are made to form a device for unloading the contents of the package, while the device for unloading the contents of the package contains a tray with an exhaust element and sides with end elements that ensure fixation of the tray to the surface of the top flap of the package in its open state.

However, this design of the device for unloading packaging has disadvantages, which are expressed in the fact that when installing the tray in the open state, the end elements of the sides of the tray allow the tray to be installed in a position where the opening angle is <90°. This position of the tray significantly limits the user's view of the area where the package contents are unloaded onto the tray. In conditions of limited visibility, the user is forced to resort to additional manipulations of the packaging to encourage the release of the contents. When folding the tray back inside the package, there is a possibility that the tray will fall inside the package, because The main fixation for this is only the thin edge part of the top flap of the package and the thin edge part of the unloading device, which is an unreliable means of fixation. In addition, the unloading device is located in the middle part of the top flap of the package, which leads to the appearance of blind spots on both sides of the device, the selection of contents from which is significantly difficult.

Another device for unloading the contents of a package is also known from the prior art, described in US patent 2,064,029, publ. 12/15/1936, class. B65D 33/36, (which is the closest analogue) containing a tray with sides and an exhaust element. The device for unloading the contents of the package is made on the narrow side wall of the package, as its continuation, which includes a tray for unloading with side edges that secure the tray in the open state, and an exhaust element as a protruding part of the tray for unloading.

However, this device also has design disadvantages, which are expressed in the fact that the width of the tray is equal to the width of the side wall of the package. And this leads to the fact that the amount of content unloaded from the packaging onto the tray may be disproportionately greater than the user needs. Those. the process of unloading content becomes uncontrollable. In addition, the device for unloading the contents of the package is fixed in a position where the opening angle cannot be >90°. This forces the user to make additional efforts to encourage the contents on the tray to drain into the container, i.e. make unnecessary movements that require good coordination. When the tray is folded back into the package, the rough edge of the tray will frictionally engage with the adjacent rough edge of the protruding portion of the package body, thereby holding the fixture in the closed position without the use of separate fastening means. However, this retention in the closed position is not completely reliable; if the package is turned on its side (or upside down), then there is a possibility of the contents coming out of the package under the influence of the weight of the contents.

The essence of the proposed decision

The technical problem that is solved by the claimed device is associated with eliminating the disadvantages of analogues known from the prior art.

The technical result that can be obtained by implementing this technical solution is to ensure reliable multiple fixation of the unloading device, both in the folded (closed) state, to cover the opening for unloading, and in the open state, at any angle selected by the user opening of the device, and as a result - increasing the controllability of the process of unloading the contents from the package.

The specified technical result is achieved by creating a device for unloading the contents of the package, placed above the opening of the package, including a tray with sides, an outlet valve and a support element, while in its folded state, the tray is located under the outlet valve and is held on the support element, where the outlet valve equipped with flaps designed to hold the sides of the tray and form an opening when the tray is switched to the open state.

In this case, the tray is made with the ability to tilt into the open state at an angle greater than 90°, and the ends of the sides of the tray on its three sides are free from attachments. The tray has an exhaust element, and

- 1 043999 slots are made on the supporting element. When folded, the tray is held by the sides of the tray, located in the slots made on the support element. In addition, the outlet valve flaps hold the tray in the folded state on the support element.

In a particular case of making a device for unloading, its elements - a tray with sides, an outlet valve and a support element can be made integral with the packaging formed from a single development.

In another particular case of making a device for unloading, the tray with sides, the outlet valve and the support element are made in the form of separate elements, with the possibility of installing these elements on the package above the outlet hole made on the package.

In another particular case of making a device for unloading, the tray with sides, the outlet valve and the support element can be a single structure, with the possibility of installing it on the package above the outlet hole made on the package.

In another particular case of making a device for unloading, the tray with sides, the outlet valve and the support element can be made in the form of a combination of elements, partly installed on the package and partly separately from it, with the possibility of attaching them to the package above the outlet hole made on the package.

The advantage of the claimed solution for a device for unloading the contents of a package is the ability to tilt the tray of the device for unloading at an angle greater than 90°, while maintaining the ability to tilt the tray of the device at angles less than 90°. This is achieved due to the fact that the sides of the tray are not attached to the package on which the unloading device is located, but are attached to the tray with only one of their edges along the long sides of the tray and the user can tilt the tray to the required angle. This position of the tray allows the user to control the viewing area of the outlet of the device for free unloading of the contents of the package, without additional manipulations with the packaging due to the possibility of installing the tray at an angle exceeding the angles of friction on the surface of the tray of the contents being unloaded from the package.

In this case, the user-selected position of the tray is reliably fixed by pressing the sides of the tray, from their outer side, with the release valve flaps. Additionally, such an angle for unloading the contents of the package provides the user with a complete opening of the viewing area for the device, and, as a result, maintaining control over the process of unloading the contents through the outlet.

After unloading the contents of the package, the outlet can be securely closed due to the fact that the tray can be freely returned to its original position through the outlet valve, close the outlet with the tray and fix the sides of the tray in the slots made on the support element. Additionally, the tray on top can be covered with outlet valve flaps, the connection line of which can be made curved so that the protruding elements of one flap are placed between the protruding elements of the opposite flap, forming connections like a flat zipper, and, due to the friction of the end surfaces nested in each other other protruding elements of the flaps, are held in the folded state, providing additional resistance to arbitrary opening of the packaging outlet.

Thus, the inventive device for unloading the contents of a package differs from solutions known from the prior art for devices for unloading the contents of a package.

Description of the invention

The present invention relates to a device suitable for discharging the contents of the package on which it is placed, for example, a powdered or granular product such as tea, coffee, cereals. The packaging itself can have different shapes and is made of flexible material, such as cardboard.

The invention is further disclosed in more detail with reference to the accompanying drawings, which schematically depict the structural elements of the device and options for its application.

More specifically, in FIG. 1 schematically shows a device for unloading the contents of a package.

The device for unloading the contents of the package 1 is placed above the outlet 12 of the package 1, and includes a tray 2 for unloading, on two sides of which there are sides 3 that limit the exit of the contents from the package 1 beyond the tray 2. The sides 3 can have a different shape, rectangular , rounded, figured, providing the function they perform. Sides 3 are attached with one of their edges to tray 2, all other edges of side 3 are free from fastening. On one more side of the tray 2, for example, by creasing, a line of weakened strength 18 is made (not indicated in Fig. 1), connecting the tray 2 with the exhaust element 4. The exhaust element 4 is a protrusion at the end of the tray 2, and the presence of a line of weakened strength 18 provides the ability to bend the exhaust element 4 in the plane of the tray 2. In this case, the line of weakened strength 18 can be made curved, which increases the rigidity of the exhaust element 4 after it is bent.

Another important element of the device for unloading the contents of the package 1 is the outlet valve 5 (see Fig. 2), which is formed by longitudinal flaps 6 and an end flap 7 with a label 8.

In fig. 2 illustrates the outlet valve 5 in a closed state. The outlet valve 5 is located above the tray 2 (not shown in Fig. 2) to unload the contents of the package 1. In the outlet valve 5, in its middle part, by means of creasing, a line of weakened strength 19 is made. The line of weakened strength 19 can be made straight or zigzag , with the formation of zigzag elements of the valves entering each other. When line 19 breaks, longitudinal flaps 6 are formed on the exhaust valve 5, the separation of which from each other allows the formation of an opening 11 of the exhaust valve 5. The exhaust valve 5 also includes an end flap 7, which is attached to the end sides of the longitudinal flaps 6, and has a label 8 with cutout 13 of tab 8. By turning tag 8 through cutout 13, the end flap 7 is separated with a bend along the line of weakened strength 20 from the outlet valve 5 and longitudinal flaps 6, providing access to the exhaust element 4 of tray 2. This makes it possible to pull the exhaust element 4, separate the longitudinal flaps 6 at the point where the line of weakened strength 19 of the outlet valve 5 passes and form an opening 11 through which tray 2 can be placed in the open state to unload the contents of the package 1 (see Fig. 1). In the open state, tray 2 is held due to frictional forces between the sides 3 of tray 2 and the longitudinal flaps 6 of the outlet valve 5, which are elastic stops for the sides 3 of tray 2. As previously mentioned, the advantage of this design is the fact that tray 2 is a fixture to unload the contents of the package 1 is securely held open due to the fact that the sides 3 of tray 2 are covered on both sides by the longitudinal flaps 6 of the outlet valve 5, but at the same time tray 2 can be in the open state, with a deviation from the package 1 at an angle >90 ° due to the fact that the sides 3 of the tray 2 are not attached to the package 1, in contrast to designs known from the prior art. The outer surfaces of the sides 3 of the tray 2, and the surfaces of the longitudinal flaps 6 of the outlet valve 5 in contact with them, can be made in relief so that the protruding parts of the surface of the sides 3 coincide with the depressions of the surface of the longitudinal flaps 6 to ensure reliable contact of the surfaces.

For each specific product contained in package 1, clearly visible lines can be additionally applied to the surfaces of the longitudinal flaps, indicating the optimal angle at which it is proposed to tilt tray 2, allowing for the unloading of the optimal amount of package contents. For the same purpose, on the contacting surfaces of the sides 3 of the tray 2 and the longitudinal flaps 6 of the outlet valve 5, special convexities and depressions can be made, tactilely indicating to the user that the optimal angle of rotation of the tray has been achieved for this particular product - contents packing 1.

In fig. 1 illustrates another structural element of the inventive device, namely, the support element 9. The support element 9 can be either part of the package 1 or be a separate element that can be attached to the package 1 in a known manner. The support element 9 is designed in such a way that the end part of the tray 2 rests on the surface of the support element 9, preventing the tray 2 from falling into the internal space of the package 1 when folding the device after use. Also, the support element 9 is equipped at one of its free ends with slots 10 (see Fig. 3-4), which can be straight or rounded. The slots 10 serve to securely hold the sides 3 of the tray 2 of the device for unloading the contents of the package 1, by wedging the sides 3 into the slots 10 when folding this tray after use inside the package, keeping said sides 3 from spontaneously coming out of the slots 10 under the influence of the weight of the contents from inside the package on tray 2 during various manipulations with a closed package, or turning over a closed package.

In fig. 1 also illustrates an outlet 12, which is provided on the package 1 and serves to allow the contents discharged from the package 1 to pass through it. The outlet 12 coincides with the outlet 21 of the support member and the outlet 11 of the outlet valve. The outlet opening 21 of the support element 9 serves to allow the contents unloaded from the package 1 to pass through it. In this case, the length of the hole 21 in the support element 9 must be less than the length of the tray 2, and the width of the hole 21 in the support element must be equal to the width of the tray 2 along the outer size of its sides 3. The length of the hole 21 of the support valve 9 determines the maximum flow rate that can be achieved when unloading the contents from package 1. In this case, reducing the length of hole 21 proportionally reduces the maximum flow rate achieved when unloading the contents from package 1, and vice versa, increasing the length of hole 21 increases the specified maximum flow rate.

The inventive device for unloading the contents of package 1 can be used in the following way.

A device for unloading the contents of package 1, consisting of a tray 2 with sides 3 and an exhaust element 4, an outlet valve 5 with longitudinal flaps 6 and an end flap 7 and a support element 9, is installed above the outlet 12 located on the package 1. In order to packaging 1 to unload a portion of the contents, the user, along the line of weakened strength 20, opens the end flap 7, which has a pre-made cutout 13 on the exhaust label 8. Having hooked the label 8 by the cutout 13, the user bends the end flap 7 by force, opening access to the exhaust element 4 of the tray 2. By bending the exhaust element 4 of tray 2 and grabbing it, the user uses force to move tray 2 from the folded state to the unloading position. When tray 2 is pulled out and rotated by the exhaust element 4, the bridges break along the line of weakened strength 19, and the longitudinal flaps 6 bend, forming the opening 11 of the exhaust valve 5. The opening 11 of the exhaust valve 5 corresponds in width to tray 2. Due to the fact that the sides The 3 trays 2 are disconnected from the sides of the package 1, this allows the user to tilt the tray 2 to unload the contents of the package 1 at an angle greater than 90° and securely hold it in this position due to the friction forces between the sides 3 of the tray 2 and the longitudinal flaps 6 of the outlet valve 5, which are elastic stops for the sides 3 of tray 2 and do not require additional means of fastening. All this allows you to reliably bring tray 2 into the open state and hold it in this position for the time necessary for unloading. This tilted position of tray 2 at an angle greater than 90° allows the user to maintain maximum visibility of the area of the outlet 21 of the support element 9 located under tray 2, and to organize a controlled, controlled unloading of the dosed portion of the contents of the package 1 into the container, without additional manipulations with the package 1, by tilting packaging 1 and unloading the contents through tray 2 into the container. The sides 3 of tray 2 reliably protect the unloaded portion of the contents of package 1 from spilling.

After unloading the required portion of the contents of the package 1, tray 2 can be returned to its original (folded) state inside the package 1. To do this, the user, holding the exhaust element 4, lowers the tray 2 through the opening 11 of the outlet valve 5 until it rests on the surface of the support element 9 The presence of an exhaust element 4 of tray 2 allows the user not to come into contact with the surface of tray 2 itself, ensuring conditions of sanitary standards. In this case, the user fixes the sides 3 of the tray 2 in the slots 10 of the supporting element 9. The slots 10 are made in such a way that when tray 2 is folded inside the package 1, the sides 3 fit into the slots 10 to the full height of the sides 3, wedge into them and ensure reliable fixation of the tray 2 in the folded state, which closes the hole 21 of the support element 9 and the outlet hole 12 of the package 1, and thereby prevents spontaneous unloading of the contents of the package 1 through the opening 11 of the outlet valve 5 and the hole 21 of the support element 9 during various spatial manipulations with the package 1. To make it easier for the sides 3 of the tray 2 to fit into the slots 10 of the support element 9, chamfers or roundings can be made on the leading parts of the slots 10.

Thus, the claimed invention, described by the combination of the listed features,

- 4 043999 provides reliable repeated opening and closing of the opening for unloading the contents of the package after unloading part of the contents, and also improves controllability and simplifies the unloading process.

Examples of the implementation of the device, which are non-limiting illustrations of the implementation of the claimed invention.

Example 1.

A device for unloading the contents of the package can be made on the package in the form of a box with an outlet hole and made of cardboard, which when unfolded represents a single development (Fig. 3). Such a package 1 has sides 14, top flaps 15 and bottom flaps 16. The elements of the device 17 for unloading the contents of the package 1 are made integrally with this reamer, from its main parts.

Thus, tray 2 with sides 3 and exhaust element 4 is mounted on one of the upper flaps 15 of package 1.

The longitudinal 6 and end flaps 7 with the label 8 of the outlet valve 5 are also made from the adjacent top flap 15 of the package 1, so that the longitudinal flaps 6 in their folded state are connected by means of a line of weakened strength 19, which can be made in the form of a straight line, or represent a curved line, which ensures reliable retention of the longitudinal flaps 6 with each other, in their folded state, and enhances the effect of their mutual adhesion. Separation of the valves 6 and 7 from each other allows you to form an opening 11 of the exhaust valve 5.

The support element 9 is made from another upper valve 15 of the package 1 and is equipped with a hole 21 for releasing the contents from the package 1 and slots 10 for holding the flaps 3 of the tray 2 in them when the tray 2 is in the folded state.

After connecting the side sides 14, the top flaps 15 and the bottom flaps 16 of the reamer to each other, a package in the form of a box is obtained (see Fig. 1-2). Where the elements - a tray with sides, a release valve and a support element of the device 17 for unloading the contents of the package are placed above each other and above the opening 12 of the package 1. Unloading the contents of this box can be carried out by using the device 17 for unloading the contents of the package in the manner described previously.

Example 2.

In fig. 4 illustrates the second embodiment of the device for unloading the contents of the package, when the tray 2 with sides 3 and the exhaust element 4, the outlet valve 5 formed by the longitudinal flaps 6 and the end flap 7 with a label 8 and the supporting element 9 with slots 10 and hole 21, are separate structural elements of the specified device for unloading and which are sequentially installed above each other and above the hole 12 made on the package 1. The connection of the specified elements of the device for unloading the contents of the package is carried out in a known way, and unloading the contents of the package can be carried out by using the device for unloading as described earlier way.

Example 3.

In fig. Figure 5 illustrates another example of a device for unloading the contents of a package, when tray 2 with sides 3 and exhaust element 4, outlet valve 5 formed by longitudinal flaps 6 and end flap 7 with label 8 and support element 9 with slots 10 and hole 21 represent is a pre-assembled device and which is installed above the opening 12 made on the package 1. Unloading the contents of the package can be carried out by using the unloading device in the previously described manner.

Example 4.

In another particular example of the implementation of the inventive device for unloading the contents of the package (not shown in the figures), when the tray 2 with sides 3 and the exhaust element 4, the outlet valve 5 formed by the longitudinal flaps 6 and the end flap 7 with a label 8 and the support element 9 with slots 10 and hole 21, can be made in the form of a combination of elements, partially installed on the package 1 and partially separately from it, with the possibility of attaching them to the package 1 above the outlet 12 made on the package 1. Unloading the contents of the package can be carried out by using devices for unloading in the manner described previously.
