Description

  The present invention relates to a lid that closes a container, such as a can or any other container made of glass, plastic, or other suitable material. In particular, the present invention relates to a lid for use in cans for gradually consuming powdered or particulate bulk products such as certain foods and chemicals.

  Certain powdered or particulate bulk products, such as any food or potentially toxic or corrosive chemicals, must be kept sealed and the containers in which they are presented on the market before A clear visual indication to the consumer that it has not been opened needs to be provided.

  Since many of these products are consuming gradually, the lid that gives access to the contents of the can after the container is opened for the first time, is reclosed while consuming the stored product gradually It is essential that the sealed can can be reclosed as many times as necessary to ensure hermeticity and protect the contents remaining in it.

  In the art, a can is well known in which a lid is press-fitted to a surrounding structure ring portion that is inside the upper edge portion of a can body and is hermetically sealed and double-wound. In this type of construction, the hermeticity of the contents is ensured at the same time as the lid is fitted in the seat for seating and holding the lid, which is provided in the structural ring defining the upper annular wall of the can.

  Brazilian patent application No. 0003727-3 by the same applicant is a plastic lid, and is attached to a detachable sealing part which is seated and held on a seating part, and is arranged around an upper edge of the sealing part. A lid is described, which is provided with a pair of gripping strips that are generally semi-annular with both ends incorporated into the upper edge. The gripping strip is lifted from the inoperative position flush with the upper edge to the center after the rupturable means to connect the central area of the gripping strip to the sealing part of the plastic lid is torn. Can be displaced. At the operating position of the gripping strip, the user grips them and pulls out the can lid.

  Brazil patent application No. 0203950-8, also by the same applicant, discloses a plastic lid for cans, the sealing part which it comprises as a single piece is opened for the first time. An interrupting portion is provided that extends through the width of the upper annulus and at least a portion of the height of the lower skirt of the can in the circumferential extension. The closure portion of the lid incorporates a gripping tab that protrudes from the interrupting portion of the seal and can be actuated by hand only by breaking a portion of the seal. The user need only bend his finger into the shape of a hook and pull the lid out of the can.

  As can be seen, the above-described structure as well as other prior art structures have a plastic lid molded as a single piece, but the main problems are optimizing the closure of the lid and the metal seal. It also optimizes the provision of a tamper-evident seal that can be easily and safely broken without causing the user to be injured as would typically occur when the

  While the traditional problems inherent in known can closures have been solved, new problems have arisen, particularly when the contents are made of powdered or particulate material. Occurs when the is opened. Since the user pulls out the lid from time to time and pulls it out in the axial direction of the container, the container suddenly opens, and at that moment the lid is removed, forming a negative pressure at the opening of the container, Drag the particulate material and eventually sprinkle it. In addition to ruining and losing the product in this way, depending on the contents of the container there is also a risk of injury to the user or poisoning of the user.

  Accordingly, it is an object of the present invention to provide a lid for a container such as a can that guides the user to gently remove the lid to avoid undesirably sprinkling or dragging out the contents of the container. It is.

  This and other objects and advantages of the present invention include a closed end portion as a single piece having a peripheral area that is removably press-fitted to a seat provided on the container and incorporates a sealing portion for retention. This is achieved by providing a container lid of the type.

  According to the present invention, the lid further comprises a handle having at least one peripheral portion incorporated and seated in each extension of the peripheral area of the closed portion, and a central portion raised with respect to the closed end portion. The peripheral portion of the handle and the adjacent portion of the central portion are cut out by at least one radial cutout, and the fingertip terminal of at least one finger of the user is inserted radially from the outside to the inside of the lid And defining a radial opening having a dimension sufficient to allow the user's palm and / or wrist to be placed in the area of the sealed portion that is diametrically opposed to the radial opening. Thus, the user's hand forms a lever to help the user gradually open the lid from the surrounding area adjacent to the radial opening.

  The structural configuration of the lid of the present invention forces the user to remove the lid at an angle using the hand as a lever. As a result, the lid is gently removed to avoid abrupt air displacement at the opening of the container, which in the prior art could cause the lid to scatter or drag the contents of the container.

  The present invention is described below with reference to the accompanying drawings.

  According to the accompanying drawings, the present invention is a lid 30 made of a plastic material, such as polypropylene, polyamide, or any other suitable material, as a single piece by injection or otherwise molding, Incorporates a sealing portion 32 with a suitable structure to be removably seated and held in a seat “S” provided in the container 10 made of plastic, glass, or any other suitable material.

The circumferential rib 11a is defined by at least a portion of a circular arc, and the annular upper wall 11 has an outer edge with a seating portion "S" defined therein. The outer edge on the opposite side of the part is usually attached to the upper edge 10a of the peripheral side wall of the container 10 by double winding.

  Also in the embodiment shown in FIGS. 1 and 2, the sealing portion 32 of the lid 30 is defined by a circumferential cradle 32a, the cross section of the circumferential cradle 32a is in the form of an arc, on the inside of which the lid 30 is a container. When closed, the circumferential rib 11a of the annular upper wall 11 of the container 10 is fitted.

  The sealing portion 32 can also incorporate a continuous outer peripheral flange 32b that is seated on the adjacent portion of the annular upper wall 11 of the container 10 when the circumferential rib 11a is fitted to the circumferential cradle 32a of the lid 30. Then, the lid 30 is maintained in the closed state of the opening “A” of the container 10.

  On the other hand, in the embodiment shown in FIG. 3 and FIG. 4, the seating “S” of the container 10 is a suspended cylindrical protrusion 12 incorporated upward at the edge of the opening “A” provided in the annular upper wall 11. Defined by The suspended cylindrical protrusion 12 is curved inside the opening “A” so as to form a continuous cylindrical rib 13 that can have a circular shape, for example, and then upwards into the suspended cylindrical protrusion 12. A lower end portion that is curved towards is provided.

  Still in the embodiment shown in FIGS. 3 and 4, the peripheral area 31a of the closed end portion 31 of the lid 30 has an upper free edge 31b which is curved outward, downward and then towards the peripheral area 31a.
