Description

A container for products, in particular for fruit or vegetables

The present invention relates to a container of a transparent plastic material.

The container according to the invention is preferably manufactured from PET and is used to contain products, in particular fruit or vegetables.

The prior art containers of a flexible transparent plastic material for fruit or vegetables come in various shapes and sizes, and consist essentially of an open top container body and an articulated lid to the container body along a side, designed to close the top of the container and present adequate retention means to keep the lid in the closed position.

The retention means usually consist of pressurized die-cast parts that form at the edges of the container opposite the articulated side.

Vessels of the prior art of this type, such as those of GB 2 339 766, are reinforced to protect the fruit or vegetables they contain (and to enable them to be stacked conveniently for storage and transport) . The reinforcement consists of suitable reinforcement ribs in the form of molded projections that are distributed along the side walls of the container body and the lid and which also extend over the top of the lid.

A disadvantage of prior art containers of this type is due to the shape of the reinforcement ribs and their distribution over the different parts of the container.

In fact, these ribs normally protrude from the plane defined by the walls of the container and have a substantially arc-shaped cross section.

Reinforcement ribs of the prior art of this type have the disadvantage of preventing the contained products from being properly seen, mainly due to the fact that the shape of the rib distortes the view of the product inside the offered container. from outside the container, which means that consumers are prevented from fully appreciating the quality of the products inside such prior art containers.

To address the present deficiency of the prior art, the present invention provides a container for products, in particular for fruit or vegetables or similar products, according to claim 1.

The rib of the type that is disclosed confers considerable rigidity to, and reinforces, the container. In addition, such a rib does not distort the view of the products in the container offered from outside the container itself.

According to another advantageous aspect of the invention, to further increase the rigidity of the container according to the invention, the side thereof opposite to that in which the lid is articulated to the container body comprises mutual engagement means, designed to prevent the lid from sliding sideways in relation to the container body. In this way, the lid and the container body cooperate more effectively to confer greater structural rigidity to the container as a whole.

Other advantageous aspects of the container according to the present invention are set forth in the other claims.

The technical characteristics and advantageous aspects of the invention are evident from the detailed description that follows, with reference to the attached drawings, which illustrate the preferred embodiments of the invention, provided merely by way of example without restricting the scope of the concept. inventive, and in which:

Figure 11 is a cross section of an enlarged detail, similar to that of Figure 6, of the fourth preferred embodiment of the container according to the present invention.

With reference to the accompanying drawings, the first preferred embodiment 10 of the container according to the present invention is made of a transparent plastic material, in particular PET, and comprises an open top container body 12, which has a plurality of side walls, labeled 14, 16, 18, 20 in the drawings, and a substantially horizontal bottom, labeled 22.

The container according to the invention also comprises a lid 24 associated with the container body 12 in such a way as to close the same and which, in turn, comprises corresponding short side walls 26, 28, 30, 32, each one of which is connected, through a respective curved connecting wall, to a horizontal upper part 34 that forms part of the lid.

The curved connecting walls, labeled 36, 38, 40, 42 in the accompanying drawings, extend along the sides of the lid according to the guidelines of a corresponding cylindrical surface, that is, in a manner such as to forming a sector of a cylindrical surface, which joins the side walls of the lid to the horizontal upper part 34 of the lid.

As illustrated, the connection walls of the cover 24 comprise a plurality of ribs, collectively labeled 44.

The shape of the ribs 44 includes a curved portion 44a, which is recessed or serrated in relation to the respective curved connecting wall 36, 38, 40, 42 and extending transversely according to the guidelines of a cylindrical surface correspondent.

The recessed portion 44a of the rib 44 is joined to the corresponding curved connecting wall 36, 38, 40, 42 by means of opposite lateral reinforcement portions 44b, 44c extending from the opposite edges of the recessed portion 44a and which They are found in substantially vertical planes.

The substantially vertical reinforcing portions 44b, 44c form a "segment-like" surface that extends between the recessed portion 44a and the curved connecting wall 36, 38, 40, 42 and whose height h (see detail of Figure 6), or the radial distance between portions 44a and 36, 38, 40, 42 curves, increases to a maximum (h) at an intermediate point of the reinforcing portion 44b, 44c.

The reinforcing portions 44b, 44c formed in this way confer considerable flexural stiffness to the rib.

In addition, the shaped rib 44 as described above allows the product inside the container to be properly viewed, because there are no corrugated or curved surfaces to distort the view of the product, as occurs with the ribs. of reinforcement on the prior art containers.

The interior of the container is vented by means of orifice 46. These holes are made in the recessed portion 44a of the rib 44.

More specifically, the orifice means consist of an elliptical or oblong opening 46, the width of which is approximately one third of the width of the lowered portion 44a of the rib 44. Preferably, the opening is placed in the center inside the portion lowered, as shown in the drawings.

To allow good ventilation and to allow the contents of the container to be properly seen, the ventilation opening 46 extends along a length substantially equal to the length of the recessed portion 44a, but is slightly longer in the end thereof extending over the top of the lid.

As illustrated, the side walls 26, 28, 30, 32 of the lid comprise, respectively, a vertical bottom portion 26a, 28a, 30a, 32a, which forms a single piece with a portion 33a, 33b, 33c, 33d of corresponding horizontal perimeter, of a lower peripheral lip 33 of the lid.

The lower vertical portion 26a, 28a, 30a, 32a joins, through a peripheral substantially horizontal stepped portion 26b, 28b, 30b, 32b, to a vertical wall portion 26c, 28c, 30c, 32c extending vertically and which, at the top, forms a single piece with the corresponding upper connection wall 36, 38, 40, 42, through a corresponding substantially horizontal stepped portion 26d, 28d, 30d, 32d.

The upper portions 26c, 28c of the sides of the cover have reinforcement ribs, labeled 48. Looking more closely, some of these are found in the ribs 44 made on the long sides of the connection walls of the lid, in the openings 46. As illustrated, the ribs 48 are approximately of a width equal to the holes 46 and are designed to reinforce the portions in the vicinity of the openings themselves.

As illustrated, the ribs 48 comprise a flat recessed portion 48a and molded parts 48b, 48c on the opposite side.

Corresponding reinforcing ribs 50 are made in the lower portion of the side wall of the cover in the curved corner portions 25, 27, 29, 31 of the side walls.

The ribs 50 comprise a flat recessed portion 50a and molded parts 50b, 50c on the opposite side.

As illustrated, reinforcement ribs 48, similar to the widest ribs 44 that are made in the portions that join the top of the lid, are made in the upper portions of the side walls, in the corner portions of the lid, to coincide with the ribs 50. Therefore, the corners of the lid are reinforced and highly resistant.

Numbers 35 in the drawings indicate pressure molded parts designed to hold the lid in the closed position and comprising protruding closure portions that fit into matching receptacle portions that are made in the container body in a manner such as to close the lid and keep it in the closed position.

On the opposite side to that on which the pressure-molded molded parts 35, 35 are made, there is an articulation portion whereby the lid pivotally joins the container body.

This articulation portion, which is indicated in its entirety by the number 37 in the drawings, comprises two long molded portions having a substantially C-shaped cross section, labeled 37a, 37b and joined to each other by a band portion horizontal, labeled 37c.

The side opposite the articulated side also comprises suitable means, which are indicated in their entirety by the numbers 52 and 54, by which the lid engages with, and rests on, the container body.

In addition, the portion 52 on the lid acts in conjunction with the portion 54, which projects upwardly from the upper edge of the longitudinal wall 14 of the container body.

More specifically, the first engagement means 52 are made in an intermediate area of one of the walls of the lid and extend from a lower edge of this wall towards the upper edge of a coincident wall of the container body to engage with the second coupling means 54 projecting from the upper edge of the wall of the container body.

Advantageously, the first coupling means on the cover take the form of wide teeth 52a, 52b, 52c, which fit in the coincident spaces between the teeth 54a, 54b, 54c, 54d of the second coupling means on the container body

This guarantees a secure closure and prevents the lid from sliding sideways in relation to the container body.

These teeth have surfaces 52 ’, 52 ″ and 54’, 54 ”of convergent lateral contact, which engage with each other.

This facilitates the insertion of the teeth inside the matching tooth spaces, which ensures a complete adjustment that avoids lateral movements between the lid and the body and confers compactness and rigidity to the container according to the invention.

Advantageously, these means for engaging and retaining the lid sideways on the container body are made on the side walls opposite the joint 37, which joins the lid to the container body. Therefore, the side wall of the lid rests on the coincident side wall of the container body, which confers greater flexural rigidity to the lid wall and, therefore, also greater rigidity to the part of above the lid.

Advantageously, the latch retention means and laterally comprise teeth with substantially semicircular profiles, labeled 52a, 52b, 52c, which extend downwardly from the horizontal lip 33b protruding horizontally from the corresponding vertical wall of the container lid.

The coincident semicircular teeth 54a, 54b and arc-shaped portions of end 54c, 54d, on each side of the central teeth 54a, 54b, extend along the upper edge of the corresponding wall of the container body and they are conveniently separated in a manner such as to form spaces for housing substantially semicircular teeth 52a, 52b, 52c, of the engagement means on the lid of the container.

As illustrated, the semicircular teeth that are formed on the container body fit into the semicircular spaces that are made by the conveniently separated teeth 52a, 52b, 52c that are formed on the lid of the container.

The tooth configuration described above uniformly distributes the force applied to the tooth, thereby avoiding excessive deformation on the tooth and significantly reducing the risk of teeth deforming.

The thickness of the contact surfaces 52 ’, 52 ″ and 54 ″, 54” of the engagement teeth is such as to ensure a good distribution of the retention action laterally between the lid and the container body.

As clearly shown in Figure 1, the lower teeth extend from a side portion of a peripheral lip 33 of the container body, which - thanks to the hooking means 52 and 54 and the joint 37 - is keeps the peripheral lip 35a slightly free of the lid, leaving an air gap S through which the product is vented inside the container.

According to another aspect of the invention, as illustrated in the drawings, the upper portions 26c, 28c, 30c, 32c of the side walls 26, 28, 30, 32 of the cover comprise reinforcing portions 56, which they protrude from the corresponding wall and which extend from the horizontal stepped portion 26b, 28b, 30b, 32b that joins the lower portions 26a, 28a, 30a, 32a of the side walls to the upper portions of the side walls of the top.

The protruding portions 56 constitute means for reinforcing the side walls of the lid.

Looking in more detail at the container body 12, it can be seen that the bottom 22 is attached to the side walls by a corresponding recessed portion 14a, 16a, 18a, 20a in the form of a curved portion connecting the walls 14, 16, 18, 20 lateral to the bottom 22 of the container body.

The side walls of the container body 14, 16, 18, 20 are joined to each other by means of arc-shaped portions indicated by numbers 15, 17, 21 and 23 in Figure 4.

According to another advantageous aspect of the invention, the reinforcement ribs on the side walls of the lid are made only in, or in the vicinity of, these curved connecting portions 15, 17, 21, 23 at the corners of the body of container.

These reinforcement ribs at the corners of the container body allow the product inside to be seen clearly through the walls of the container, but without weakening the structure of the container itself.

More specifically, these corner reinforcement ribs take the form of "wear" and comprise a first substantially flat recessed portion, labeled 60a, which is connected by ribbed portions, labeled 60b and 60c, to adjacent portions of the wall side.

As illustrated in the drawings, these reinforced rib portions 60b and 60c are convergent upwards.

These "raised" ribs are made on the long sides 14, 16 of the container.

The corners that join the long sides 14, 16 to the short sides 18, 20 also have second reinforcement ribs.

Each of these second "raised" ribs comprises a recessed portion, labeled 62a, which has side portions, labeled 62b and 62c, which bind it to adjacent portions that are in the same plane as the side walls of the container body Again, these portions of the reinforcing ribs 62 are convergent upwards, as illustrated.

As illustrated in the drawings, the reinforcement portions 60, 62 recessed on the container body define similar recessed reinforcement portions 60 ', 62' in section 14a, 16a, 18a, 20a below the container body .

The above characteristics confer resistance to the container body without using vertical ribs, such as those of prior art containers of a similar type, on the intermediate portions of the container body, and thus offering a clear view of the products in the inside of the container

The container body further comprises reinforcing portions, labeled 66, which extend vertically on, and protrude from, the corresponding walls of the container on each side of the corner ribs 62.

As illustrated in the drawings, the lid also has a top surface designed to engage with the bottom of a container placed above it, this top surface being delimited by an essentially quadrangular edge 34 'extending in a level slightly higher than the point above the connecting portion 36, 38, 40, 42.

More specifically, as illustrated in Figure 6, the lower edge 44'a of the rib surfaces showing only the rib 44c in Figure 6 - has a radius Ri of curvature that is greater than the radius Re of curvature of the edge 44'c upper surface 44c of rib.

As illustrated, the convexity of these edges, which define the rib surface, is oriented upwards, that is, it is oriented towards the outside of the container.

More specifically, the ratio between the radius Ri of curvature of the lower edge 44'a and the radius Re of curvature of the upper edge 44'c varies advantageously from 1.2 to 2 and is preferably between 1.3 and 1, 8 ideally 1.5.

Advantageously, the radius Re of curvature of the upper edge 44'c ranges from 5 to 15 mm and is preferably between 7 and 13 mm, ideally 10 mm, while the radius Ri of curvature of the lower edge 44'a varies from 10 to 20 mm and is preferably between 12 and 18 mm, ideally 15 mm.

More specifically, as clearly illustrated in Figure 6, which shows only the rib 44c, each rib has a lower end extending from the stepped portion 28d whose thickness or height is less than the maximum height or thickness h of the rib itself while, at the opposite end, the edges of the rib are convergent and join with each other at the top of the lid.

In addition, the width "L" of the intermediate connection portion 44a, which extends between the first and second lateral reinforcement portions 44b, 44c, ranges from 6 to 18 mm, is preferably between 8 and 14 mm and, ideally, 12 mm This gives sufficient stiffness to the rib while, at the same time, it is transparent so that the product inside the container can be seen clearly.

Looking in more detail, the oblong ventilation opening 46 is preferably 4 to 8 mm wide and, ideally, has a width "l" of 5 mm.

According to another advantageous aspect, each of the corner portions 25 ’, 27’, 29 ’, 31’ 31 ’has the shape of a vault that connects side walls adjacent to the transverse top surface 34.

Advantageously, each corner portion 25 ', 27', 29 ', 31' in the shape of a vault has, in the horizontal plane, a radius of curvature "Ro" which varies from 14 to 20 mm and is preferably 17 mm , while the radius of curvature "Re" of each portion 25 ', 27', 29 ', 31' of a vaulted corner in any vertical plane may vary from 5 to 15 mm, preferably between 7 and 13 mm, and It is, ideally, 10 mm.

As illustrated, the vaulted corner portion 25 'is delimited laterally by a first reinforcement rib 44', which is made in a portion 36 of the lid, and by a second reinforcement rib 44 ", made on a portion 40 adjacent to (and with right angles with) that in which the first reinforcement rib is made. This confers considerable rigidity to the corner portion.

In addition, the height Vl of the side walls 26, 28, 30, 32 is less than the height Vr of the connecting portion 36, 38, 40, 42.

Looking in more detail, the height V'l of the lower vertical portions 26a, 28a, 30a, 32a, and the height V "l of the upper vertical portions 26c, 28c, 30c, 32c of the walls 26, 28, 30, 32 sides of the lid are substantially the same.

As illustrated, the container body 12 has reinforcing ribs on its side walls only in the corner portions, conferring a structural rigidity to the container as a whole, while at the same time providing a better view of the interior of the container .

The reinforcing ribs, which are made only in the corner portions of the side walls of the container body 12, are delimited by the vertical protruding reinforcing portions 66.

Each rib 44 extends beyond the circumferential edge 34 'that delimits the upper transverse surface 34 and does not protrude upward relative to this upper transverse surface 34, which makes it possible to obtain a rigid structure that can be made using a simplified mold of lower cost.

Figure 8 illustrates a second preferred embodiment 100 of the container according to the present invention, the present embodiment being substantially the same as the first preferred embodiment, from which it differs in that it has a lesser number of ribs, labeled 144 , the short sides of the container having only a rib 144 that is made in each of them.

In another embodiment, which is illustrated in an exploded view in Figure 9, the lid 224 is not articulated to the container body as in the embodiments described above, but is separated from the container body 212. The container, in the present third preferred embodiment 200, is of a substantially square shape when viewed from above, and its lid has the same number of ribs 244 over all four

5 faces of it.

Figures 10 and 11 illustrate a fourth preferred embodiment 300 of the container. In these illustrations, parts of the fourth embodiment that are identical to those of the first preferred embodiment are indicated by the same reference characters. In the fourth preferred embodiment, the rib surfaces 344b and 344c of the rib 344 on the lid begin in a stepped portion 345, which extends horizontally between the

10 space or recess defined by the rib surfaces 344b and 344c, starting from a substantially vertical extension 328e of the horizontal stepped portion 28d of the lid. This confers greater rigidity to the part at the base of the rib, which makes the container more resistant as a whole to vertical loads.

The first preferred embodiment of the vessel illustrated is approximately 187.5 mm long, 118 mm

15 wide and 90 mm high. The second preferred embodiment of the vessel illustrated is approximately 127.5 mm long, 96.5 mm wide and 80 mm high. In the third preferred embodiment of the vessel illustrated, the length of the sides is approximately 186 mm and the height is 114 mm. You can, however, imagine containers with different dimensions from the previous ones. The container according to the present invention is manufactured by molding a plastic material, especially by thermoforming.

It will be understood that the invention may be subject to modifications and variations without thereby departing from the scope of the claims. In addition, all the details of the invention can be replaced by technically equivalent elements.
