Abstract

The utility model relates to storage containers, namely hermetically sealed containers. A container lid is offered, which is made of thin-sheet polymer material of a rectangular shape with rounded corners. The lid has a rectangular central part and an L-shaped belt molded along its periphery, the upper shelf of which is located above the surface level of the central part and is connected by a flat wall to the central part. On the central part, on opposite sides, there are recesses in which folding latches are installed. Each latch consists of sequentially connected sections: a lower horizontal section installed in the recess of the central part with the possibility of rotation relative to the central part, a central vertical section, an upper horizontal section and an extreme vertical section with a lock. The thrust part of the latch is located between the latch rotation axis and the upper horizontal section. The technical result consists in ensuring reliable fixation of the lid on the container and increasing its service life due to the design of the latches.

Description

The utility model relates to storage containers, namely hermetically sealed containers.

A package is known that contains a container associated with a lid equipped with reversible and reusable locking means. The cover is made of plastic, contains a central closing panel, extending with a peripheral boundary section having a cross-section in the shape of an inverted letter "U", the bottom of which is equipped with a seal. In addition, the lid comprises at its periphery at least two locking tabs, each of which includes at least a locking portion suitable for releasably engaging an external structural member referred to as a "complementary locking structural member" located on the side of the upper boundary portion of the container body, during the operation of rotating the locking tab to the “locked” position, and the corresponding interaction simultaneously includes the approach between said peripheral boundary portion of the lid and the upper edge of the container to achieve compression of the seal (according to patent RU2424167, B65D 43 /26, published 07/20/2011).

The disadvantage of this solution is the unreliable fastening of the locking tabs, which can be destroyed after repeated use.

A container and a sealed lid are known. The container has a bottom wall and a vertical peripheral wall ending in an upper edge surrounding an open neck. The replacement cap has a central top flat wall and an inverted U-shaped periphery that ends in an outer rim skirt. A pair of latches rotate on a cap adjacent to the outer skirt of the rim and are positioned to engage protruding latch hooks on the peripheral wall of the container to release the cap over the neck of the container (US Pat. No. 7,090,089, B65D 45/16, publ. 08/15/2006 ).

Also known is a lid having a plurality of molded latches, each of which is hinged on the molded lid, and a container closed by the molded lid. Each latch is hingedly supported by a clamp mounted between the molded cover and the latch. The lid molding includes at least one formation for each latch, whereby a stop will be formed that will reduce the likelihood of the latch being pulled away from the lid molding as a result of the latch moving upward about its rotation axis. Each latch provides at least one cylindrical surface that can be secured by at least one latch element, thereby providing a trunnion bearing defining the axis of rotation (US Patent 8596485, B65D 45/16, publ. 05.08. 2008).

The disadvantage of these solutions is the unreliability of fixing the latches on the container, associated with the location of the rotation axis of each latch relative to the stops interacting with the container.

The closest technical solution is a storage container, which includes a body and a removable lid. The removable lid includes a flexible sealing lip that extends around the perimeter of the rigid center portion of the lid. At least one vent hole may extend through the rigid center portion of the lid. Additionally, the storage container may include a latch movable between a locked position and an unlocked position. The latch may include a gripping portion configured to engage a peripheral edge of the container body and a sealing portion configured to close the vent hole when the latch is in a locked position. When the latch is in the unlocked position, the sealing portion can open the vent to allow steam and other gases to escape from inside the storage container (US Pat. No. 10173826, B65D 81/34, B65D 45/18, published 01/08/2019).

The description of the cover design does not indicate the relative position of the latch's rotation axis and the locking protrusion on it. The reliability of the latch when it is fixed and removed from the container depends on this.

The technical result of the proposed utility model is to ensure reliable fixation of the lid on the container and increase its service life due to the design of the latches.

This technical result is achieved by the fact that the container lid is made of thin-sheet polymer material of a rectangular shape with rounded corners, has a rectangular central part and an L-shaped belt molded along its periphery, the upper shelf of which is located above the surface level of the central part and is connected by a flat wall to in the central part, on the central part on opposite sides there are recesses in which folding latches are installed, each latch consists of sequentially connected sections: a lower horizontal section installed in the recess of the central part with the possibility of rotation relative to the central part, a central vertical section, an upper horizontal section and extreme vertical section with a latch, and is characterized in that the thrust part of the latch is located between the axis of rotation of the latch and the upper horizontal section.

For the purposes of this application, the terms "top" and "bottom" refer to the position of the lid when mounted on the container, just as the terms "horizontal" and "vertical" are generally relative positions and may allow for some deviation from the horizontal and vertical positions, respectively.

The utility model is illustrated by drawings, which show:

fig. 2 – container lid without latches, axonometry;

fig. 3 – latch, axonometry;

fig. 4 – container lid, cross section;

fig. 5 – container lid with raised latches, axonometry.

The lid 1 (Fig. 1) of the container is made of thin-sheet polymer material of a rectangular shape with rounded corners 2. The lid 1 has a central part 3 of a rectangular shape and an L-shaped belt molded along its periphery, consisting of an upper shelf 4 and a flat wall 5. Upper shelf 4 is located above the surface level of the central part 3 and is connected by a flat wall 5 with the central part 3. On the central part 3, folding latches 6 are installed on opposite sides. The latches 6 are installed in recesses 7 (Fig. 2), at the ends of which holes 8 are located.

The latch 6 (Fig. 3) consists of sequentially connected sections: a lower horizontal section 9, a central vertical section 10, an upper horizontal section 11 and an outer vertical section 12 with a latch 13. On the lower horizontal section 9 there are cylindrical projections 14, which are inserted into the holes 8 recesses 7 and provide rotation of the latch 6.

The thrust part 15 (Fig.4) of the latch 13 is located between the axis of rotation 16 of the latch 6 and the upper horizontal section 11.

Application.

Cover 1 is used in conjunction with a container of the appropriate shape. The lid 1 can be used to seal, for example, a food container. The lid 1 is put on the container (not shown in Fig.), while the latches 6 (Fig. 5) are raised and then lowered, covering the protruding edge of the container on both sides. After that, the latches 6, with the application of force to the outermost vertical sections 12, snap into place in such a way that the latch 13 engages with the edge of the container, ensuring that the lid 1 is tightly pressed. To open the container, it is necessary to pull the outermost vertical sections 12 away from the container so that the latch 13 comes out from engagement with the edge of the container. After this, the cover can be removed.

The location of the thrust part 15 of the latch 13 between the rotation axis 16 of the latch 6 and the upper horizontal section 11 ensures reliable fixation of the lid 6 on the container. In this case, when closing and opening, a large deformation of the latch 6 is not required, which is possible when the thrust part 15 of the latch 13 is located below the axis of rotation 16. Since in this case a stronger deformation of the outermost vertical section 12 will be required, based on the trajectory of its movement when turning the latch 6 .

Thus, the proposed technical solution ensures reliable fixation of the lid on the container and increases its service life due to the design of the latches, and thereby allows achieving the stated technical result.
