Description

Container lid for container.

Field of the invention

The present invention concerns a lid container container, which comprises a closed compartment  which contains a material that can flow, such as a sauce suitable for a salad or other product arranged in the container, when sufficient external force is applied to said cover and this is attached to the mouth of a corresponding container. When the lid is not attached to a container, it is capable of resist crushing, constituting a unit that allows both its storage and its transport without breaking the compartment, when supported on a surface.

Background of the invention

Different packaging proposals are known divided into several compartments or cameras, each containing of them a different substance or material and being able to mix said substances after the breakage of the wall separating said compartments

Serve as an example of this kind of packaging the US4836370, which proposes a container divided by a dividing wall, in two receiving chambers. Each camera houses in its inside a different material, for example a yogurt in one and some cereal flakes in the other. The container includes components structural that will create an opening in the dividing wall in response to a predetermined manipulation of the external part of the container so as to allow the material contained in the two Cameras combine into one. Different examples of realization with different forms of containers, cameras and, especially of structural components to offer different alternatives for breaking the dividing wall and, consequently,  the mixing of the two types of materials. While any of these alternatives propose a breakage system similar to proposed by the present invention, it is linked to full container, since the lid is not claimed but the container, in addition to lacking an option that prevents breakage of the dividing wall when an external pressure occurs.

Devices with a double are also known function, to serve as a lid for a container and to be them Same container containers of different kinds of substances. The Following documents give a fairly accurate idea of the state of the Technique of such devices:

The utility model, in the public domain, ES-A-231221 proposes a cover container for boats intended to be applied to a boat or similar container, which may contain an article that, without being of nature related to the contents of the boat, must be supplied together with it. The document claims that the content of said cover is a promotional item, such as a series of discs to be used as templates for He drew. To access this article it is necessary to separate from the cover an auxiliary disk that does the basic functions to support the article contained inside. In said utility model it is not indicated that the contents of said lid can be a material liable to flow, such as a sauce, nor that it is liable to be mixed with a second material contained in the canister where said lid is attached.

US2766796 proposes a receptacle that It serves as a cover, capable of containing inside Different vacuum packed products, such as products pharmaceutical or food, which can be mixed, a once removed, with the contents of the container on which it is attached Said receptacle. Unlike the present invention so that mixing the contents of both, the receptacle used as lid and the container on which it is attached, is produced is necessary remove a cover from the receptacle at the top and also remove the receptacle from the container, that is to say that both the receptacle and the container, are coupled in an indivisorial way, since the wall that separates them, the base of the receptacle, is not breakable

US3662913 also proposes a cover which also does the functions of packaging, similar to the one proposed by the present invention, but with the main difference that here the dividing wall of the lid and the container on which it is placed it is not breakable, but must be extracted manually, previously removing the lid of the container.

US5255812 describes a cover of container with an internal chamber to hold a liquid. Wall  The bottom of the chamber is flat and provides a central area weakened, the upper wall of the chamber is a membrane deformable from an initial configuration convex to a configuration flat end when exerting pressure on it. Top wall integrates a piercing member that projects to the wall lower. When the user presses the upper wall, the member perforator bore the weakened area of the lower wall, thus causing the liquid stored inside the chamber internal flow to the related container. The periphery of the lid is configured as an annular flange with an annular groove bottom to engage the peripheral edge of the container and a upper raised annular edge. The upper raised annular edge acts as a support that allows stacking several covers of container.

US4634003 describes a container for separately accommodate a couple of liquids, such as water mineral and whiskey, which includes a main body to accommodate a first liquid, a small cup to accommodate a second liquid, provided with a flange that extends from the entire periphery of an upper end of the small cup and a skirt that projects down from the entire periphery of an upper end of the flange, and a flexible lid to seal against the passage of liquids a top free opening of the small cup. The little cup is fits into a top free opening of the main body by coupling  the flange and skirt with all the periphery of an upper end of the main body. The small cup has a specified area, on a bottom wall, at least partially bordered by a line branded. The lid has a downward projection. Area specified is broken by pushing down the lid until a Projection tip presses to break the specified area, through which the second liquid flows down entering the main body and mixes with the first liquid in the body principal.

It is therefore necessary to offer an alternative to the state of the art as far as this class of devices is refers, that offer, unlike the antecedents commented, a triple function, to serve as a receptacle and container capable of keep and store a first substance inside, thanks to the solidity of its base in storage situation, which can serve as a lid of a container container that may contain a second substance, and that facilitate the mixing of said substances by breaking a dividing wall that makes base of said lid, without the need to remove the lid of the container to carry out said action and, in turn, allow that after said break the discharge of the fluid product or substance can be done in a staggered way, depending on the amount of said first substance to be supplied, that is to say allow a dosage at the user's discretion.

Brief exposition of the invention

The present invention proposes a cover container container, which comprises a series of walls laminar delimiting a compartment, closed, containing a material that can flow, such as a sauce. That cover It has a support configuration capable of resisting a crushing said compartment when it is supported On a surface. It also includes a perimeter configuration closure adapted to be attached to the mouth of a corresponding container covering the compartment, and at least one weakened area formed in a lower laminar wall, which makes the base lid times, adapted to be broken by a deformation of the compartment caused by the application of a sufficient external force, enabling this breakage the discharge of said material capable of flowing into Said container.

Thanks to that weakened area formed in said lower laminar wall is only breakable when the lid It is attached to the container, and not when it is supported on a surface, the lid can also be used to store and keep the material inside, being able to stack some covers over others without risk of breakage.

The container on which the lid is placed could contain a second substance that would be mixed, in the container, with the material capable of flowing contained in the lid, once the Lower laminar wall of it was broken.

Detailed description of an embodiment example

As the attached figures show, the cover container container proposed by the present invention together it comprises an upper laminar wall 1; a wall lower laminar 2; at least one perimeter laminar wall 3, of low height in relation to the extension of said walls upper and lower laminar 1, 2, and extending between upper and lower laminar walls 1, 2 delimiting a compartment 4, closed, containing a material capable of flow; at least one support configuration 5 formed in at least one of the upper or lower laminar walls 1, 2 and susceptible of making contact with the other of the lower laminar walls or upper 2.1 to resist crushing said compartment 4 when it is supported on a surface; a closing perimeter configuration 7 adapted to be attached to the mouth of a corresponding container 8 covering the compartment 4; and at least one weakened zone 6 formed in the lower laminar wall 2 adapted to be broken by deformation of compartment 4 caused by the application of a force sufficient exterior in order to pour said susceptible material of flowing into said container 8.

In Figs. 3, 4 and 6 can look like the wall lower laminar 2 comprises at least one configuration of lower expansion 9 defined by a fold that extends to along a closed contour surrounding said weakened area 6 and liable to deploy downwards due to said force exterior forming a discharge funnel finished in said area weakened 6 rotates when the lid is installed in the container 8. It can also be seen how the upper laminar wall 1 comprises at least one upper expansion configuration 10 defined by a crease that extends along a closed contour.

In a preferred embodiment, said lower laminar wall 2 and said perimeter laminar wall 3 form a single sheet, which is stackable on other equal sheets, in a non-fitting way, for storage and transport.

In Figs. 3, 4 and 6 can be seen as said lower expansion configuration 9 is sunk inward  of compartment 4 and said upper expansion configuration 10 it is substantially symmetrical to speculate about said lower expansion configuration 9, including both lower and upper expansion configurations 9, 10 ones respective peaks of support in mutual contact, which constitute the cited support configuration 5, which is at least one. also can be seen as at least the bottom laminar wall 2 comprises several of said lower expansion configurations 9, in an arrangement concentric surrounding said weakened area 6, which delimit some annular portions of compartment 4 and which are susceptible to deploy stepwise from the most central to the most peripheral as the external force applied with the in order to dose the spillage of the product contained in said annular portions of the compartment 4.

In Figs. 3, 5 and 6 can look like the wall upper laminar 1 has integrated or joined a prominence 11 that extends into the compartment 4 facing said weakened area 6 of the lower laminar wall 2 and adapted to break said weakened zone 6 when said outer force is applied on the upper laminar wall 1.

The lid proposed by the present invention is formed by a first sheet 20 that integrates the laminar wall upper 1 and said closing perimeter configuration 7, and a second sheet 30 that integrates the lower laminar wall 2, the wall perimeter laminar 3, which is at least one, and a binding strip perimeter 12 attached to a lower face of said first sheet 20, said perimeter junction strip 12 being smaller than the closing perimeter configuration 7, which is free. This way subsets 20 and 30 can be fed automatically in a machine for lid manufacturing container of the invention. For this purpose it is also planned that subset 30 has a configuration that allows stacking no fit between each of the units, partially introduced in the twin.

In the exemplary embodiment shown in Fig. 6 the perimeter closure configuration 7 comprises a flat band adapted to be attached to a corresponding flat band 13 formed next to a mouth of the container 8. Instead in another example of embodiment, shown in Fig. 3, the perimeter configuration of closure 7 comprises a groove adapted to receive fitted to press a corresponding flange 14 formed next to a container mouth 8.

A configuration can be seen in Fig. 7 different from lid with a substantially square shape, to unlike the previous embodiments in that this It was circular, once it has been attached to a container, logically with an opening also substantially square.

Finally in Fig. 8 shows another example of embodiment in which two of the caps shown in Figs. 1, 2, 3, 4, 5 and 6 are integrated as a subset in a single cover greater than it covers both, being able to include each one of said covers a different matter, or the same, allowing a dosage major or minor

The embodiments of Figs. 9 to 11 show various alternative forms of cover execution that they are not part of the invention, with variants in the means for break one of the walls of the lid and support configurations crush resistant, offering differentiated areas for other functionalities (free area of the lid for another receptacle, etc.).

The cover to which this invention refers can defined in a generic way, contemplating the different implementations of the drawings, as a body comprising in set:

- an upper wall 1, with at least a portion flexible (to allow the other wall to break);

- a bottom wall 2;

- at least one perimeter wall 3, of sparse height in relation to the extension of said upper walls and lower 1, 2, and extending between them delimiting a compartment 4, closed, containing a material capable of flow;

- at least one weakened area 6 formed in the bottom wall 2, adapted to be broken by a deformation of the compartment 4 caused by the application of an external force sufficient in order to pour said flowable material inside said container 8;

- at least one support configuration 5 formed in at least one of the upper or lower laminar walls 1, 2 and liable to make contact with the other laminar walls lower or upper 2, 1 in order to effectively resist a crushing said compartment 4; Y

- a closing perimeter configuration 7, attached at least to the edges of one of the walls 1, 2, provided to be attached to the mouth of a corresponding container 8 spanning compartment 4 (so that when one of the breaks is broken the walls the contents of compartment 4 pass inside the cited container).

In the examples in Figs. 9 and 10, which are not part of the invention, the bottom wall is formed by a heat sealable film. On the other hand, in Fig. 11 The bottom wall is formed by a membrane.

In the examples of Figs. 9 to 11, the support configuration 5 is made from a plurality of 31 partitions or nerves that intersect along a common axis and they are spaced the same separation distance. Such configuration also helps provide stability when the caps are stacked as shown in Fig. 9c. Bliss nerve configuration 31 also provides a means to break the bottom wall in all variants of Figs. 9 a eleven.

In the variant of Figs. 10 there are at least two additional support configurations 5a, 5b formed in said wall perimeter 3, and which are constituted by generating nerves 5a, 5b protruding from the outer face of said wall 3 of the compartment 4, although they could also protrude from the face inside.

A subject matter expert could introduce changes and modifications in the described embodiments (particularly if, and because, the lid has walls or flexible portions, which allow adopting different shapes and a variety of contours) without departing from the scope of the invention according to It is defined in the attached claims.
