Another example of optional configuration, whether complementary or not, is that the base of the outer skirt (8) is parallel to the base of the cover (3) and may be in the same plane above or below it.

Examples of optional external skirt configurations (8) are illustrated in FIGURE 3.

Snap connectors (4) according to the present invention are formed by connector pairs which can be snapped together. Preferably, a same cap according to the present invention is provided with plug connectors (4) of compatible shape and size, so that two equal caps can be fitted together.

Optionally, caps according to the present invention may also contain snap-fit connectors (4) which do not allow fitting between two equal caps (for example, caps having 2mm diameter female (10) niches and cylindrical male pins (9) with 4 mm diameter), but can be compatible with other caps also according to the present invention (for example, caps having 4 mm diameter female (10) niches and 2 mm diameter male (9) cylindrical pins).

Plug connectors (4) may assume different configurations, including male pin-type systems (9) and female niches (10), as exemplified in FIGURE 4, groove systems such as those exemplified in FIGURE 5, groove systems. such as hooks and rails such as those exemplified in FIGURE 6 or systems with cutouts such as those exemplified in FIGURE 7.

In interesting constructions, the plug connectors (4) constituting the caps of the present invention are of the male pin (9) and female niche (10) type.

According to the present invention, male pins (9) are any protrusions capable of being inserted and inserted into cavities.

An example of optional conformation is that wherein the male pins (9) according to the present invention are essentially cylindrical. Also optionally, male pins (9) may have different shapes, such as polygonal prisms or other shapes. Additionally, they may also be formed of separate sets of parts which together delimit the outer perimeter of cylinders or polygonal prisms.

Interesting shape options for male pins (9) include, for example, cylindrical pins with cutouts to allow seating and engagement with another cap having constitutive elements that would coincide with the positioning of such male pins ( 9) in cap according to the present invention, if they were not cut. The presence of cut-out barrel shaped studs (9) may be particularly interesting, for example in the case of caps according to the present invention where studs (9) are present on the outer wall of the top surface (2-e). ) and female niches (10) are located in the lower portion of the other cap in positions where the base of the other cap would collide with one or more of the male pins (9) if they had fully circular cross-sections without clipping.

Still in relation to the shapes, the male pins (9) may have their slightly rounded or chamfered ends, to facilitate their introduction into female niches (10) of other caps.

According to the present invention, the male pins (9) may have various shape dimensions and dimensions. An example of an interesting optional shape and size is that of cylinders where the outside diameter of the male pins (4) is (4.8 ± 0.1), (6.5 ± 0.1) or (9.4 ± 0.2) millimeters. In the case of cylindrical male pins (4) made of non-deformable materials, the outer diameter (DE) corresponds to the diameter of the outer circular section of the pin itself. For differently shaped male studs (9) constructed of slightly deformable materials, the outer diameter (DE) corresponds to the diameter of the smallest circumference surrounding the cross section of the stud. Male pins (4) constructed of deformable materials and having a variable outside diameter (ED) when pressed shall be considered to have a diameter of (4.8 ± 0.1), (6.5 ± 0.1) millimeters or ( 9,4 ± 0,2) millimeters where they can be inserted under pressure into cylindrical holes of these diameters.

Regarding their length, the male pins (9) may have different dimensions. For example, lengths of about 1 to 10 millimeters. The use of longer studs (9) may be particularly interesting when they are constructed of more deformable materials such as polypropylene and polyethylene or when studs (9) are positioned under the inner wall of the lid surface. (2i). Especially in the case of longer male studs (9), it may be interesting to use small sleepers or walls interconnecting the base of two or more male studs (9) to prevent or minimize their deformation or misalignment over time.

Examples of possible male pin configurations (9) are illustrated in FIGURE 8.

According to the present invention, female niches (10) are any recesses into which protrusions of building blocks may be inserted and fitted, such as male pins (9) located on other covers. Female niches (10) according to the present invention may assume multiple shapes. Interesting shapes of female niches (10) that tangent at least three cylinder points that can be inserted into them are interesting.

Optional female niche shape options (10) comprise, for example, cylindrical holes, polygonal prismatic holes, inner portions of tubular ducts, essentially parallel cylinder-spaced spaces, essentially parallel flat surfaces, overhangs or fins arranged in configuration to form essentially parallel planes or combinations thereof. Essentially parallel means planes or straight lines with an angle of inclination of up to fifteen degrees to one another. In examples of optional conformations, the female niches 10 are delimited by elements totally parallel to each other.

According to the present invention, the female niches (10) may have various shape sizes and dimensions. An example of an interesting optional shape and size is that of cylindrical spans where the internal diameter (D1) of the female niches (10) is (4.8 ± 0.1) millimeters, (6.5 ± 0.1) millimeters or (9,4 ± 0,2) millimeters. In the case of cylindrical female niches (10) constructed of poorly deformable materials, the inner diameter (D1) corresponds to the diameter of the inner circular section of the niche itself. For female niches (10) of different shapes consisting of slightly deformable materials, the inside diameter (D1) corresponds to the diameter of the largest caliber cylinder that can be inserted into the niche. Female niches (10) constructed of deformable materials and having a variable internal diameter (Dl) when pressed shall be considered to have a diameter of (4.8 ± 0.1) millimeters, of (6.5 ± 0.1) millimeters. or (9,4 ± 0,2) millimeters, when cylinders of these diameters can be inserted into them under pressure.

An interesting conformation for female niches (10) is that formed by a space delimited by a male niche (10) in the form of a cylindrical tube (TC), with an outer diameter of (6.5 ± 0.1) millimeters and an inner diameter (Dl). (4.8 ± 0.1) millimeters or with an outer diameter (DE) of (13.0 ± 0.2) millimeters and an inner diameter (Dl) of (9.4 ± 0.2) millimeters by the parallel faces of two fins (AL) pointing towards the cylinder tube (TC), where the apexes of such fins (AL) and a semi-straight in the outer wall of the cylindrical tube (TC) delimit female niches (10) with internal diameters (Dl) of (4,8 ± 0,1) millimeters or (9,4 ± 0,2) millimeters, respectively.

Regarding depth, female niches (10) may have different dimensions. For example, depth of about 1 to 10 millimeters. The use of deeper female niches (10) may be particularly interesting when caps according to the present invention are combined with other caps containing longer male pins (9). Especially in the case of deeper female niches (10), it may be interesting to use small sleepers or walls interconnecting the outer walls of two or more female niches (10) to prevent or minimize their deformation or misalignment over time.

In relation to the cap location, the female niches (10) and / or the male pins (9) may be seated or attached to any cap components, including the outer surface of the top surface (2-e), or extension thereof, the inner wall of the top surface (2-i) or the side wall (1) or the optional cover skirt (6).

Depending on optional configurations, the elements forming the female niches 10 may be arranged integrally in the lid portion which is in contact with the inner part of the package to be closed. According to a second optional embodiment, the members forming the female niches (10) may be arranged partly on the part which is in contact with the inner part of the package and partly on the part which is not in contact with the inner part, as for example. , the inner wall of the outer skirt (8). According to a third optional configuration, the female niches (10) may be disposed integrally in the part that does not contact the inner part of the package. This third embodiment is particularly interesting for cases where it is not desirable to include additional elements inside the package.

Examples of possible optional configurations of female niches (10) are illustrated in FIGURE 9.

Regarding orientation, according to the present invention, the male pins (9) and / or the female niches (10) may be oriented in various ways. In an optional embodiment example, the female niches (10) and / or the male pins (9) are arranged with their longitudinal axes in a direction essentially parallel to the inner portion of the side wall (1). Essentially parallel means planes or straight lines with an angle of inclination of up to fifteen degrees to one another. In examples of optional arrangements, the male pins (9) and / or the female niches (10) are arranged with their longitudinal axes in a direction totally parallel to and between the inner portion of the sidewall (1).

As an optional specific aspect, the caps comprised by the present invention not only have male pins (9) and / or female niches (10) with specific dimensions, but also have specific spatial distributions for such pins and niches: When two or more are present male pins (9) with a diameter of (4.8 ± 0.1) or (6.5 ± 0.1) millimeters, the spatial distribution of such pins optionally corresponds to that of quadrangular matrix points formed by multiple parallel and orthogonal lines. with a distance of (8.0 ± 0.1) millimeters from each other. When two or more male pins (9) with a diameter of (9.4 ± 0.2) millimeters are present, the spatial distribution of the center of such pins corresponds to that of quadrangular matrix points formed by multiple parallel and orthogonal lines with a distance of (16 ± 0,2) millimeters to each other. When two or more female niches (10) with an internal diameter of (4.8 ± 0.1) or (6.5 ± 0.1) millimeters are present, the spatial distribution of the center of such niches corresponds to that of matrix points. square formed by multiple parallel and orthogonal lines with a distance of (8.0 ± 0.1) millimeters, optionally containing an additional female niche (10) at the intersection of the diagonal lines of the squares of such matrix. When two or more female niches (10) with an internal diameter of (9.4 ± 0.2) millimeters are present, the spatial distribution of the center of such niches corresponds to that of quadrangular matrix points formed by multiple parallel and orthogonal straight lines. (16 ± 0.2) millimeters apart, optionally containing an additional female niche (10) at the intersection of the diagonal lines of the squares of such a matrix.

Regarding the number and distribution of male pins (9) and female niches (10) may be present in different quantities and locations. In certain types of optional constructions, they feature distributions that allow caps according to the present invention to be simultaneously fitted with three or more other caps in multiple positions and configurations, including diagonal stacking of caps where one or more male studs ( 9) or female niches (10) on the same surface are available for additional fittings even when the cover is already attached to another cover. For this purpose, it may be interesting to place two or more plug connectors (4) (eg female niches (10) or male pins (9)) apart and close to the perimeter of the top surface (2) at their outer wall (2-e) and / or its inner wall (2-i).

Examples of non-removable opening systems (5) constituting the caps of the present invention include, for example, fliptop opening systems, wherein the lid opening cap (7) is formed by an overcap (11). attached to the lid by means of a hinge (12) (FIGURE 10), tilting type systems, wherein the lid opening (6) is positioned in a tilting element and the lid opening lid (7) is comprised of extension of the sidewall (1) (FIGURE 11), movable ring-type systems, wherein the lid opening lid (7) is of longitudinally sliding element in the lid opening entrance duct (6) (FIGURE 12) or further, for example, rotary disc type systems, wherein the lid opening (6) is exposed by the hole encounter in the upper surface (2) and rotary overcap hole (11) (FIGURE 13).

In an optional configuration, the non-removable opening system is of the fliptop type, where the overcap (11) is free of snap connectors (4). Such a configuration may be particularly interesting in order to prevent undesirable opening of the lid from the lid opening (7) hindering the process of assembling and disassembling connection block assemblies formed by the covers of the present invention (FIGURE 14).

In an optional configuration, the non-removable opening system is of the fliptop type, wherein the overcap (11) has snap-on connectors (4). Such a configuration may be particularly interesting when it is desired to take advantage of the hinge paper element as a functional element of building block assemblies (FIGURE 15).

Similarly, the application or not of snap-fit connectors (4) on movable elements of the lid opening assembly (6) and lid opening lid (7) can be explored in other types of opening system. For example, in rotary disc type opening systems, the rotation of the elements may be exploited so that the cap assembly with the rotary element (13) as a whole acts as the axis of rotation (FIGURE 16). In the case of non-removable movable and tilting ring-type opening systems (5), opening systems can be used both as decorative elements in locking block assemblies and as functional elements, such as for the inclusion of drains. or vents in assembly block assemblies.

According to another optional specific aspect, the covers comprised by the present invention may have parallelepipedal shape in which the top surface (2) is rectangular, with at least one lateral dimension (L) of (((N x 8) - 0.2) ± 0.2) millimeters, where N is an integer. Still in this case, optionally there will be a male pin (9) or a female niche (9) in diameter (4.8 ± 0.1) millimeters with center positioned at a distance of (((nx 8) - 4.1) + 0.1) mm from the top surface edge or there will be a male pin (9) or a female niche (10) in diameter (9.4 ± 0.2) mm with center positioned at a distance of (((nx 16) - 8,2) ± 0,2) mm from the edge of the top surface (2), where n is an integer, independent of N.

In yet another optional aspect, the caps comprised by the present invention have the top surface (2) and the base of the lid (3) in the form of parallel planes and at a height (H) of ((M x 3.2 ) ± 0,2) millimeters, where M is an integer.

In another optional aspect, the closures comprised by the present invention may be associated with a closure seal (14), which may or may not detach from the closure at the time of opening of the package. Commonly, the rupture seal (14) is shaped like a ring attached to the base of the lid (3) by means of small perforated connections or a thin wall made of the material with which the lid is made, such connections being thin or thin. wall are broken when the lid is removed from the packaging. In cases where the base of the lid (3) has small indentations or teeth, the appearance of the assemblies formed by the side wall (1), lid base (3) and molding seal (14) may be of small windows at cover base (3). FIGURE 17 presents examples of optional closure seals (14) for the caps.

In addition to its functional lid locking application and indication of packaging tampering, the use of removable molding seals (14) may be particularly interesting in cases where the distribution of plug connectors (4) over the outer wall of the sealing surface. top (2-e) and under the inner wall of the top surface (2-i) could form nestable pairs when two lids, without the sealing caps (14), were linearly stacked. In such cases, the temporary elongation of the sidewall (1) by the seal (4) may be used to prevent unwanted connection between two lids, for example in package closure lines.

Optionally, caps according to the present invention may further be provided with opening locking systems that minimize the risk of unwanted opening of the caps, such as those described, for example, in US2012211505 or WO2012094713. Example of optional embodiment of cover provided with flip-off non-removable opening system (5) wherein overcap (11) is provided with snap-on connectors (4) and wherein overcap (11) has an opening lock in the form of The bolt (15) that needs to be pushed towards the lid sidewall so that the overcap (11) can be raised to the lid opening is illustrated in FIGURE 18.

Several other additional aspects may be used in conjunction with the covers comprised by the present invention, including the use of reliefs or patterns on their surfaces that may form predetermined mosaics or figures, use of materials with different colors, transparencies and compositions. Optionally combinations of the covers of the present invention with slots, cutouts and other types of connectors may also be used, such as those described in the publications referenced on pages 1 and 2 above.

According to a second main aspect, the present invention consists of the use of the caps according to the present invention for the assembly of connected cover assemblies, by means of the plug connector socket (4) of a first cover according to the present invention with plug connector. (4) from another lid. The use of caps according to the present invention for assembling connected cap assemblies can be applied in various types of industries. For example, in the toy industry, the furniture industry, the construction industry, as a structural element of thermal insulation, sound insulation, among other applications.

According to a third main aspect, the present invention consists of closure production processes according to the present invention. Such production processes include injection or compression molding processes.
