TH5815B - Food containers with lids that are biased flexibly. - Google Patents

Abstract

A polymer container for food products is a sheet consisting of a bottom wall, an outer wall structure that extends upward from there, a lid, and all folding coverings that connect the lid to the structure. The outer wall, in which the fold-down portion causes the lid to tilt at an angle to the open position. Provide a force to keep the lid in the closed position. Determines a forced configuration that may be released by applying inward pressure to the front wall of the container, without manual internal force applied to the lid.

Claims (4)

1. a polymer container in combination with a vast number of sheets of food products stacked inside the container. The container consists of a bottom wall, an outer wall structure that extends upward from the bottom wall. A cover that consists of the top surface and the back wall extending outward from there. And all the folding closures that connect the flap to the peripheral wall structure. The hinges are soft so that the flap can be rotated through an angle of at least approximately 90 ° between the closed and open positions while still being welded to the peripheral wall structure. That can be closed. The peripheral wall structure consists of the front leather back wall, in contrast to the aforementioned rear wall. And a pair of opposite walls extending between such front and rear walls. The aforementioned peripheral wall structures and the aforementioned flap with a surface on it that define the mechanism for keeping it in stable mechanical balance in the said position. Such a soft foldable cover in a configuration under its cause corresponding to the open position of the cover contains particles of all commonly welded rectangular sections, which are described in order to operate. From the aforementioned rear wall of the said container to the said back wall of the airlock and includes the first part extending downward along that rear wall of the said cover and includes the first. That extends outward along the back wall of the container and leaves a space from there. The second segment extends generally back horizontally from the lower end of the first, third, fourth, and fifth segments, respectively, that extend upward. On the back and on the bottom, respectively With the third and fourth five approximately the same length. The sixth part that extends on the back And is less horizontal in size than the second part The seventh part extends up the way The top to the fold line which intersects with the back wall of the cover to define an upside-down U-shaped structure. A seventh segment that is less vertical than the first and has the same projected bottom edge raised to the bottom edge of the first and each cross section. The first three sections define the opening at the top, and the fifth, six, and seventh defining the opening at the top of the second with the third. Four and five define a downward opening that is positioned between the first two. The average uses the sidewalls with each other, such parts that determine their size and configuration relative to each other, and the folded part has a line of weakness at the intersection of the second and third, and the fifth and at. Six such So that, when moving the cover from its opening to the closed position, the initial rotational motion of the cover produces a bend of the folded part in the first way, which essentially consists of a line bend. Of the intersection between the second and third, and between the fifth and sixth, which can close the second compartment On its own So that the seventh is aligned with the intersection between the fourth and the fifth, and so that the first and third part move the same way to each other. And the top of the seventh section comes into contact with the first part, and so that the next replacement of the cap goes. To the closed position causing the first part to bend away from the back wall of the container. And the seventh part rotates away from the back wall of the cover until it is in its closed position. The back wall of the said cover is connected by the first such. And the seventh part connects the fourth and maintains the cover in the position closed by the mechanism forcing it. And so that in a closed position The flap was turned somewhat inclined to the open position by the foldable closure. And accumulate potential tower energy just in the foldable part to push the cover from the closed position to the open position on the occasion of release Forced mechanism 2. A combination of claim 1, which can release such a forced mechanism by hand-turning inward of the said peripheral structure without direct external force applied to such a cover. 3. Combination according to claim 1, the peripheral wall structure has a truly horizontal top edge surface, and the said cover at the corresponding area placed over that edge surface. When the cover is in the said position When such a cover has an open position, it is literally 180 ° from the said closing position, which aligns the said appropriate surface of the cover in a truly level where its raised is lower than the edge surface. Above in the above level 4.In combination according to claim 1, the aforementioned folding parts can accumulate sufficient potential energy to rotate the cover from the said closed position to the said open position for the opportunity to release the forced mechanism. say
