DESCRIPTION OF SPECIFIC EMBODIMENTS OF THE INVENTION

(5) As shown in FIG. 1, the container with fold-out opening is of the type used for storing and dispensing granulated or liquid contents or products.

(6) It comprises an initially closed vessel 1 with an essentially parallelepiped rectangular configuration, said vessel 1 resulting from the suitable bending and folding of a laminar body 2, which appears extended and represented schematically before the bending and folding thereof in FIG. 2.

(7) The laminar body 2 has transversal bending lines that define four essentially rectangular walls 21, 22, 23, 24 arranged adjacent to each other. After the suitable bending and folding of the laminar body 2, said four walls 21, 22, 23, 24 make up the lateral sides of the vessel 1.

(8) In this preferred embodiment, the four walls 21, 22, 23, 24 are in equal pairs, that is, the two walls 21 and 23 are equal to each other, and the other two walls 22, 24 are all equal to each other.

(9) The walls 21, 22, 23, 24 have an upper flap 3 that is common to them that is equipped with folding lines, which defines the upper base and an opening of the resulting vessel 1, as shall be explained bellow, and have another lower flap 4 that is common to them that is equipped with bending lines, which defines the lower support base of the resulting vessel 1.

(10) The upper flap 3 is equipped with two folding lines 31 that are symmetrical with respect to the axis of symmetry 5 of the central wall 23, said folding lines 31 being a continuation of the two bending lines 231 that define said central wall 23.

(11) Said folding lines 31 define three essentially rectangular portions 6, 7, 8 of the upper flap 3 and which are prolongations of each one of the walls 22, 23, 24 respectively.

(12) The central portion 7 has the same axis of symmetry 5 as the central wall 23 and is a continuation thereof.

(13) The other lateral portions 6, 8 are essentially symmetrical with respect to the axis of symmetry 5 and are a continuation of the walls 22, 24, respectively. Each one of the portions 6, 8 has additions 61, 81 on the edges opposite the contact thereof with the walls 22, 24.

(14) The portions 6, 8 and the additions 61, 81 have folding lines 63, 83 interposed therebetween and that simultaneously delimit the separation thereof, and which are essentially perpendicular to the axis of symmetry 5.

(15) The addition 61 has a transversal tear line 9 that is symmetrical with respect to the axis of symmetry 5 with a free edge 84 of the other addition 81, and therefore dividing the tear line 9 at the addition 61 into two dividing portions 611, 612, one dividing portion 612 being closer to the axis of symmetry 5 than the other dividing portion 611.

(16) The dividing portion 611 resulting from the path of the tear line 9 that is furthest from the axis of symmetry 5, is symmetrical to the addition 81 with respect to the same axis of symmetry 5.

(17) The portion 7 of the upper flap 3 has two folding lines 71, 72 that define three triangles. Two of them are right-angled triangles.

(18) In this preferred embodiment, the two folding lines 71, 72 are symmetrical with respect to the axis of symmetry 5, and start their path at the connection point and continue the bending lines 231 with the folding lines 31.

(19) The portions 6, 8 each have a folding line 62, 82 that defines a right-angled triangle adjacent to central portion 7.

(20) In this preferred embodiment, the folding lines 62, 82 are symmetrical with respect to the axis of symmetry 5, and start their path at the connection point and continue the bending lines 231 with the folding lines 31.

(21) Moreover, the portion 8 has a slot 10 in the right-angled triangle created by the folding line 82.

(22) The addition 81 of the portion 8 is essentially trapezoidal shaped, with the free edge 84 thereof closest to the portion 7 being arranged such that it provides a wedge shape to the addition 81.

(23) The tear line 9 and the free edge 84 are symmetrical with respect to the axis of symmetry 5, and the addition 61 has a tab 11 positioned on the dividing portion 612 thereof closest to the portion 7, and which can be engaged in the slot 10, as shall be seen below.

(24) In this preferred embodiment, the tear line 9 starts its path at the intersection point between the folding line 62 and the other folding line 63 interposed between the portion 6 and the addition 61.

(25) FIGS. 3, 4, 5, 6, 7 and 8 sequentially reproduce the opening process and subsequent closing of the vessel 1.

(26) Before it is handled, the user finds the vessel 1 closed, as seen schematically in FIG. 1, with the slot 10 covered by the tab 11.

(27) Then, the tongue 12 must be manually pulled, as seen schematically in FIG. 3. The tongue 12 is also represented in FIG. 2, with the laminar body 2 extended before the bending and folding thereof to constitute the vessel 1.

(28) The vessel 1, in its ready-to-use arrangement and before the manual manipulation and use thereof by the user, has the dividing portion 612 adhered by means of a joining means to the portion 8, in an area close to the slot 10. In this preferred embodiment, the joining means comprises an adhesive glue, which is not shown in the figures. In this way, the vessel 1 may remain closed when stored and transported before it is delivered to the user.

(29) When the tongue 12 is pulled, as well as tearing the adhesive glue that adheres the dividing portion 612 to the portion 8, the tear line 9 breaks, leaving the vessel 1 as shown schematically in FIG. 4, with the portion 7 described in the laminar body 2 oriented towards the inside of the vessel 1.

(30) The portion 7 must then be moved towards the outside of the vessel 1 so that it thus finally creates the opening 13, as shown schematically in FIGS. 5 and 6.

(31) With the opening 13 having been created in this way, the granulated or liquid content inside the vessel 1 may easily be released, it only being necessary to appropriately move and position said vessel 1 so that the opening 13 is appropriately oriented downwards in order to enable the outlet of said content due to the action of gravity, as shown schematically by the arrows in FIG. 7.

(32) The special arrangement of the opening 13 enables said outlet of the content or product housed inside the vessel 1 to be suitably controlled and channelled.

(33) To close the opening 13, the reverse operation to that explained above must be carried out, that is, the portion 7 must be moved towards the inside of the vessel 1 in order to return to the situation of FIG. 4.

(34) Then, the tab 11 must be manually inserted and adjusted in the slot 10, to ensure the permanent closure of the opening 13, the vessel 1 remaining a shown schematically in FIG. 8, with the tab 11 inserted in the slot 10 and in storage conditions.

(35) In order to successively open or close the opening 13 again, the tab 11 need only be manually removed from or inserted and adjusted in, depending on the case, the slot 10 and the unfolding or folds described above carried out, since the adhesive glue has already been initially torn and the tear line 9, having also been previously torn, does not perform any function either.

(36) In a preferred embodiment and in a condition prior to the use of the container with fold-out opening of the invention, the tongue 12 is bent and/or adhered on a lateral side adjacent to the vessel 1, as shown schematically in FIG. 9, and with the tab 11 inserted in the slot 10.

(37) This prevents possible leaks of the inner granulate or liquid product in the area of the vessel 1 in which the tongue 12 is bent.

(38) The present invention enables the manual opening of a vessel of the type commonly used for storing and dispensing granulated or liquid contents or products, and the subsequent closing thereof, which is also manual, successively, simply, effectively and securely for the uses of the user.

(39) The particular arrangement of the created and resulting opening 13 enables the user to carry out a dosage and pouring of the granulated or liquid product contained inside said vessel 1 with greater accuracy in accordance with their particular needs, unlike the possibilities of the current state of the art.

(40) The specific creation of the opening 13 in the upper base of the vessel 1, enables the free surface of the granulated or liquid product contained inside said vessel 1 to be almost touching or reaching said upper base, thus meaning that the useful volume of the vessel 1 containing the inner granulated or liquid product is almost the same as the inner geometric volume of said vessel 1.

(41) Said circumstance is a considerable advantage with respect to other vessels used in the state of the art, wherein the arrangements of the opening systems used that invade the lateral sides of the vessel reduce the useful volume with respect to the existing geometric volume.

(42) This entails significant and clear advantages in the production costs, inner storage capacity, etc.

(43) The details, shapes, dimensions and other accessory elements, as well as the materials used to manufacture the container with fold-out opening of the invention, may be suitably substituted for others which are technically equivalent, and do not diverge from the essential nature of the invention, nor the scope defined by the claims included below.
