Description

The utility model relates to containers for placing and packaging products, such as green vegetables, fruits or seedlings. In particular, we are talking about the design of packaging made of corrugated cardboard, designed to accommodate green vegetables, fruits or seedlings in individual nests in order to preserve their presentation and integrity.

Green vegetables include lettuce, spinach, leeks, celery, etc. These are perishable products that last only for several days and quickly lose their marketable qualities. Due to the large evaporation surface, green vegetables quickly fade. In addition, these vegetables are characterized by low mechanical strength and are severely damaged during harvesting and transportation. The use of plastic packaging allows you to extend the shelf life of green vegetables. In rack boxes lined with film, in plastic bags of 0.5-1.0 kg, closed tightly, lettuce, celery leaves and parsley are stored for up to 3 months with insignificant losses. Packages are set upright in crates or small vegetable containers. When storing green vegetables in plastic bags with a gas mixture, the shelf life increases to 1 ... 2 months. During long-term storage in a warehouse, green vegetables are placed in a refrigerator or in a room with a low ambient temperature. Therefore, boxes with chilled goods are transported to the consumer. The same goes for fruits.

Regarding the transportation of seedlings, it should be indicated that 1-2 days before transportation seedlings are stopped watering. This reduces the watering of the tissues, and the plants become more elastic, less brittle. To prevent the stems from being injured during rolling in vehicles, it is advisable to attach seedlings of cucumbers, zucchini, watermelons, melons, tall tomatoes and a number of ornamental plants to the support. To do this, as a rule, a strong stick is inserted into the pot at a distance of 3-4 cm from the stem and the plant is gently wrapped around it in some places, fixed with a soft rope or wire coated with a plastic sheath. This will avoid unnecessary injuries and protect seedlings from diseases. Low stem tomatoes form a thick sturdy stalk and do not require garter support. To do this, the pots with seedlings are placed in a tight box so that they are adjacent to each other and do not hang out. The height of the box is selected taking into account the height of the plants so that the upper leaves do not change when closed. Closed boxes keep warm air for a while, and plants are almost stress free.

Thus, it is clear that the issue of transporting green vegetables or seedlings requires compliance with certain rules, one of which is the reliable positioning of one item relative to adjacent items, the second is that all items to be transported should be oriented vertically, tuber or rhizome down. The third rule is that it is necessary to create certain climatic conditions inside the box or box: humidity, temperature, ventilation, etc. In addition, since green vegetables or seedlings are placed in boxes in a refrigerated state, condensation may form on the walls of the box during transportation. In this regard, it is necessary to provide means that exclude the soaking of the cardboard, which can lead to the loss of the spatial shape of the box or box made of corrugated cardboard.

So, a box for vegetables, fruits or seedlings is known, which is a four-valve box made of corrugated cardboard, formed from a sheet blank by bending along the fold lines of the lower flaps of the side walls towards each other to form a bottom used to place a lodgement with nests for green vegetables or seedlings (DE 202013000742, A47F 7/00, B65D 5/22, B65D 5/32, B65D 5/48, B65D 5/52, publ. 04.29.2014).

This decision was made as a prototype for all declared facilities.

In DE 202013000742, the lodgement is made of complex shape. In fact, the lodgement consists of two adjacent parts inside the box, each of which is a plate with holes that are nests for green vegetables or seedlings. Valves are placed on the long sides of this plate, one of which is folded up and attached to the side wall of the box, and the other, is folded down and serves as a support to the bottom of the box. Both parts are in contact with the valves bent down. With this design, the plates are at the same level above the bottom, forming a space between the bottom of the box and the plates with holes.

In the side walls of the box above the level of the location of the plates with holes made transversely elongated slots forming handles for carrying the package. And in the bottom of the box holes are made to remove moisture and ventilate the space between the bottom of the box and plates with holes. Separate items such as green vegetables or seedlings, which are rhizome or tuber in a plastic bag or in a pot and stem, are placed with a rhizome or tuber in a nest until they stop in the bottom of the box, so that the stem in a plastic bag is located in the cavity of the box above the plates. The box is closed by a lid and fed to the stack for transportation from the warehouse to the trading area.

In addition to the complexity of the design of such packaging in such a box, all the required conditions for preserving the transported goods are not created. First of all, there are no means of positioning each item placed in the nest with respect to adjacent items. After laying the rhizome in the nest, the stem can bend, which will lead to the tilt and displacement of the rhizome. In this position, the object lies on a nearby object. Since green vegetables for transportation are removed from the refrigerator, when resting on the bottom, condensation on the bottom wall leaves in the rhizomes. The bottom is soaking, which can lead to loss of the shape of the box and its bearing capacity. The presence of ventilation holes in the bottom of the box does not solve the ventilation problem, since each box in the stack is stacked with the bottom either on a pallet or on the lid below the box. In this position, these openings in the bottom of the box are always closed and closed. Lack of ventilation in the bottom leads to dampening of the bottom and loss of bearing capacity.

When transporting green vegetables packed in plastic packaging, the likelihood of wetting the bottom is significantly less, but it exists, since these bags are easily torn. But there is always condensation on these bags. And when transporting seedlings, the likelihood of gulf and getting wet bottom of the box is incredibly high.

This useful model is aimed at achieving a technical result, which consists in improving the performance of the box by maintaining the spatial shape of the box when forming the bottom of the ventilation openings of a developed area.

The specified technical result is achieved in that in a box for vegetables or seedlings, which is a four-valve box made of corrugated cardboard, formed from a sheet blank by bending along the fold lines of the lower flaps of the side walls towards each other to form a bottom, used to place a tray-shaped insert under the vegetables or seedlings, each lower valve of each side wall is connected to the lower valve of an adjacent side wall through a fold line passing through the fold line of these adjacent but located side walls, while in each valve of each side wall the fold line is made of two segments located opposite each other and at a distance from each other, while on each lower valve additional fold lines are made parallel to the fold lines of the side walls and extended from the ends of the segments facing each other to the edge of the lower valve along its long side.

For a box, the insert can be made in the form of a lodgement with nests for laying seedlings or vegetables. Moreover, in this lodgement, the nests are recesses, some of which are made with a depth greater than the depth of other nests. Part of the nests in the lodgement can be located opposite the sections of the cross-shaped bottom of the box between the walls of these sections in the cavity of the cross-shaped bottom of the box.

The lid of the box can be made in the form of a tray put on on the side walls of the box or made in the form of upper flaps of the box bent towards each other.

Two parallel lines of weakened cross-section can be made along the perimeter of the side walls with the formation of a tear tape to separate the upper part of the box from the bottom, and an opening is made on one of the side walls at the location of the tear tape to allow this tape to be caught and torn out.

Through holes can be made in the box in one side wall of the box opposite each other at a level above the tear-off tape, and in other side walls of the box located opposite each other at a level above the tear-off tape, holes can be formed in the area from these holes to the top the edges of these side walls of the handle.

These features are significant and are interconnected with the formation of a stable set of essential features sufficient to obtain the desired technical result.

The present utility model is illustrated by a specific example of execution, which, however, is not the only possible one, but clearly demonstrates the possibility of achieving the required technical result.

According to this utility model, the design of a box made of corrugated cardboard is considered, designed to place green vegetables, fruits or seedlings in individual nests of the lodgement in order to preserve their presentation and not to be damaged before this product enters the trading area. In addition, the design of the box under consideration allows for a demonstration in the form of a showcase in the trading floor of a product laid in a lodgement.

The box for green vegetables (fruits) or seedlings contains a four-valve box made of corrugated cardboard and a lodgement with nests for green vegetables or seedlings placed on the bottom of the box.

A four-valve box made of corrugated cardboard is formed from a sheet blank (Fig. 1) by inflection along the fold lines of the lower flaps of the side walls towards each other to form a bottom. The four-valve box, which has the shape of a parallelepiped, is formed by the method of bending its parts along the fold lines from a sheet blank with the formation of a bottom (bottom) and side walls 1. In FIG. 2 shows a general view of such a box assembly. The lateral walls in the form of rectangles are interconnected by fold lines 2. After bending, the side walls 1 are connected to each other by one of the known methods (gluing, staples, etc.) by attaching a valve 3 at one of the extreme side walls to the side wall 1 s opposite side of the workpiece.

The upper part of the box can be made in the form of upper valves 4, which are a continuation of the side walls 1. To form a cover for the box, these valves are bent from the side walls towards each other. The box can be made without top valves. For such an example of the box execution, the lid can be made in the form of a tray placed on the side walls of the box, turned upside down.

The bottom (bottom) or bottom zone of the box is made in a cross-shaped form from the lower valves 5, which extend from the side walls 1. The lower adjacent valves are interconnected through the fold line 5, which coincides with the fold line 2 of adjacent side walls, the continuation of which these valves are .

The bend line of each lower valve is made discontinuous in the middle part of the valve with the formation of two sections 6 and 7, the ends facing each other connected to additional bend lines 8 directed from these ends to the valve edge perpendicular to these sections (additional lines are made on each lower valve fold 8, parallel to the fold lines of the side walls and stretched from the opposite ends of the segments to the edge of the lower valve along its long side). These additional fold lines 8, together with the fold lines from two sections 6 and 7, are designed to press the surface parts of the lower flaps located between the additional fold lines of adjacent lower flaps into the cavity of the box (Fig. 2) to form a cross-shaped bottom plan ( Fig. 4). To eliminate overvoltage in the gorfromaterial during indentation of the lower walls of the side walls with a longer length along the communication line with the lower valves, additional lines of weakened cross-section or fold lines are made 9. When the parts of the lower valves are bent, a cross-shaped bottom is formed in the form of flat bottom sections 10 and side walls 11 along the perimeter of these sections (see Fig. 4). In fact, the bottom turns into a tray that has a cruciform shape in plan. The bottom of this tray is the support of the whole box, that is, the bottom of the box. Moreover, the corner zones of the bottom of the entire box (as can be seen in Fig. 4) are ventilation windows of a developed area. These windows are open not only in terms of the box, but also on the side of the side walls, which is guaranteed to blow out the bottom of the box and ventilation of the internal cavity of the box, even if it is placed in a stack.

An insert is placed on the cross-shaped bottom of the box, which is the area for placing green vegetables, or fruits, or seedlings. In a simple design, this insert can be made in the form of a tray with means that exclude contact between the objects. But the most rational is the execution of the liner in the form of a lodgement 12 with nests 13 for laying seedlings or vegetables (Fig. 2). In the lodgement, nests 13 for laying seedlings or vegetables are made in the form of recesses, part 14 of which are made with a depth greater than the depth of the recesses 15 of the other nests. Moreover, part of the nests in the lodgement are located opposite the cross-shaped sections in the plan of the bottom of the box for placing the bottom parts of these recesses between the walls of the cross-shaped sections in the bottom plan (Fig. 5). The lodgement is made of pulper cardboard (made of molded paper fiber (FBV)) and is a lamellar base in which nests are made in the form of recesses, some of which, located in the corner zones, are made deeper than the other depths. Part of the nests in the tool tray is located opposite the sections of the cross-shaped bottom of the box between the walls of these sections in the cavity of the cross-shaped bottom of the box. Thus, the recesses of lower height are placed in a cross-shaped bottom tray between the walls 11, and the recesses of greater height are located in the corner zones of the open ventilation openings of the bottom of the box and partially serve as an additional support for the entire bottom of the box. In this case, through the ventilation openings in the bottom, air exchange is provided between the bottom walls and the lodgement walls forming the recesses and the surrounding external environment. Pulpboard cardboard belongs to the environmentally friendly type of material, holds its spatial shape well even when wet, has good adhesion to a large number of surfaces of different nature of origin. High grip qualities allow you to securely hold the item, even if it is packed in a plastic film or placed in a bag of polyethylene material in the position in which it was placed in the nest. Thus, the lower zone of the liner is in a state of open access to the external environment, which allows you to dry wet areas naturally during storage or transportation. In addition, the lodgement is guaranteed to be securely laid on the bottom of the box and is the power part of this bottom, eliminating the deformation of the spatial shape of the box. In addition, pulper cardboard in the form of a lodgement can be used as portioned nests for land with seedlings.

A feature of the box is also that along the perimeter of the side walls there are two parallel lines 16 of weakened cross section for forming the tear-off tape 17 in order to separate the upper part 18 of the box from the lower part 19 of the box in which the lodgement is placed (Fig. 5). On one of the side walls or on several side walls at the location of the tear-off tape or at the place of its location, a hole 20 or several holes 20 (Fig. 1) is made for the fingers to be able to grip this tape and tear it out (see Fig. 5).

As a rule, greens enter the trading floor when the box lid is removed or the upper valves are open. This is done so that the buyer can get the item out of the box. But at the same time, the item itself is not completely visible, which leads to the fact that the buyer begins to choose, taking out one item after another. When re-styling an object that is not of a good appearance, a styling violation occurs, which leads to damage to the presentation of the product. In addition, with high side walls of the box, it becomes inconvenient to take the goods out of the box. If seedlings are placed in the lodgement, then the process of removing one item leads to damage by a number of stacked items. To eliminate this phenomenon, it is proposed that when setting up a box of goods on the trading floor, a box with a lodgement should be turned into a display case.

When tearing a tear tape, which is stretched around the perimeter of the box, the upper part 18 of the box is separated from its lower part, in which the lodgement is located. In the example of FIG. 5, it is shown that the tear tape is parallel to the lower edge of each side wall. But this is optional. This tape can be made arbitrarily located on the side walls. The main thing is that the separation of the upper part of the box from the bottom occurs at a level above the location of the lodgement. In this case, parts of the side walls enclose the lodgement, do not allow it to move, but at the same time, the products in the lodgement become visually accessible to the buyer from all sides, which will allow you to choose the product without removing it from the lodgement.

Through one side wall of the box opposite each other at a level above the tear-off tape, through holes 21 can be made through which air is exchanged between the box cavity and the external environment if this air exchange is necessary for a particular type of green vegetables or seedlings. And for the convenience of carrying the boxes in the other side walls of the box located opposite each other at a level above the tear-off tape, holes 22 are formed which form a handle from these holes to the upper edge of these side walls of the handle. These handles also function as openings for air exchange of the box cavity with the external environment.

This utility model is industrially applicable; it can be manufactured using industrial technologies for cutting blanks from corrugated cardboard with subsequent assembly and laying of the nesting box from pulper cardboard. Such a box makes it possible to reliably hold greens or seedlings in the nests and at the same time divides the box cavity into a sub-well well-ventilated zone and a super-root zone, in which moderate air exchange is maintained to maintain moisture in the foliage. The novelty also lies in the form of execution of the bottom of the box, which is made crosswise and simultaneously solves two functions: it organizes ventilation openings for blowing the lodgement and is a seat for the nests of the lodgement, which leads to an increase in the bearing capacity of the bottom and maintaining the spatial shape of the box. An additional effect is the organization of a display case from a drawer to ensure visual accessibility of the goods.
