RU203818U1 - Industrial tray with reinforced edge - Google Patents

Abstract

The utility model relates to industrial trays with a reinforced rim designed for storing and transporting bread, bakery and confectionery products. The technical result, which consists in increasing the rigidity of the front side of the tray, excluding its deflection, is provided due to the presence of three sides in the tray with a reinforced flange, equipped with stiffening ribs and flanging, along the entire length of the front side, a channel is made into which a metal spoke is inserted. 2 c.p. f-ly, 5 dwg

Description

The utility model relates to three-sided plastic trays for storing and transporting bread, bakery and confectionery products and can be used for multi-turn circulation by industrial bakery enterprises, small bakeries.

Trays for bakery and confectionery products, according to GOST 8227-56, must be made of materials permitted by the Ministry of Health for contact with hot bakery products: wood, metal, coated or uncoated polymer materials.

Recently, bakeries are switching to plastic trays and boxes because they have a number of advantages. After each use, the trays, as established by the sanitary rules and norms of SanPiN 2.3.4.545-96, must be washed with hot water and disinfected at least once every 5 days. Obviously, the service life of plastic trays for this reason is much longer compared to wooden ones. Plastic trays are not confirmed to be infested and reproduced by insects as they do in wooden trays, indicating an additional hygiene benefit. Plastic trays are lighter, well ventilated, and have two possible transport positions: when the trays are empty or when filled with products. In the position with the products, the plastic trays are stacked on top of each other, empty they are put one inside the other. With the use of plastic trays, it became possible to use standard vans instead of specialized bread trucks. The dimensions of the plastic tray are in accordance with established standards.

So, from the prior art, a plastic tray for bakery and confectionery products RU104 540 (publication date 05/20/2011, B65D 1/34) is known, in which the end walls have different heights, the side walls of the tray are mated to the front end wall by means of side bevels; flanging is made along the upper cut of the side and rear end walls; the rear end and side walls are provided with grooves of different sizes, made in pairs; end back and side walls are provided with stiffening ribs. With all the advantages of the known tray, it has disadvantages. When hot bread from ovens is put into a tray, the plastic loses its load-bearing properties due to the high temperature and sags under the weight of the bread, which leads to deformation of the tray, especially in three-sided trays with different heights of the end walls, since the design does not provide for strengthening the rigidity of the front of the tray. This decision was made as the closest analogue.

The problem to be solved by the present utility model is to modify the transport multi-turn stackable three-sided tray, which would eliminate its deformation. When solving this problem, a technical result is achieved , which consists in increasing the rigidity of the front side of the tray, excluding its deflection. Taking into account the specifics of the device (contact with food), when achieving the specified result, it is important to comply with the requirements of sanitary rules and norms for the material and processing of trays.

The technical result is achieved due to the fact that in an industrial tray made of plastic containing a bottom, side and end walls, three sides are equipped with stiffeners and flanging, a channel is made along the entire length of the front wall, into which a metal spoke is inserted, and the channel contains holes (perforations), staggered. Metal spoke with food grade powder paint

The tray is made of food grade plastic, which does not affect the taste of food, is safe, environmentally friendly and is approved for contact with food, such as low pressure polyethylene (HDPE).

Tray sizes can be 700x465x145 / 95/65/25, 600x400x100 / 75/120/410, which meet the established standards.

The tray has a bottom 1, a side board 2, a rear end board 3 and a front end board 4, the height of which is lower than the rear 3. The bottom 1 and sides 2 and 3 of the tray can be perforated or solid (without perforation). The sides of the tray 2, 3 contain a flange 5, which makes it possible to stack the trays. Also, the tray is equipped with stiffening ribs 6 for the frame reinforcement of the plastic.

Unlike the closest analogue in the proposed solution, it is proposed to strengthen the front bead 4 with a metal spoke 7, for which a channel 8 is provided in the bead 4 for its installation. Channel 8 is a narrow hollow space along the length of the entire bead 4. In this case, the upper 9 and lower 10 sides of the bead 4 are made perforated, and the holes of the correct shape are arranged in a staggered manner. Considering that the trays are washed with water after each use, the execution of perforations (holes) and their staggered arrangement allows water not to linger in the channel, to flow out of the holes. The spoke is made of metal and painted with a powder paint approved for contact with food products. The spoke is located along the entire length of the channel. The spoke reinforces the rigidity of the low bead so that the bead does not bend. From general knowledge, it is also obvious to a specialist that making a knitting needle from a different material (wood or plastic) would not ensure the achievement of the specified result.

Example 1 of the implementation of the utility model is shown in Fig. 1-4.

3-sided stacking tray with perforated sides and bottom. The absence of a front end board allows for increased ventilation of the stacked bakery products. The presence of flanges and ribs of rigidity allows stacking products in a pile, which saves space in the enterprise and in transport. The front board is equipped with a metal spoke, so when stacking hot bread, it does not bend. The tray is a reusable container for storing and transporting bread and pastries.

Example 2 (Fig. 5) is characterized in that the bottom is solid without perforation.

Thus, the presence of a perforated channel 8 in the front end board 4 with a metal spoke 7 located inside reinforces the low board, increasing its rigidity, thereby eliminating the sag of the tray.
