Background of the Invention

Field of the Invention

The invention consists of: 1) an airtight lid fitted by pressure to protect containers closed by the graph and opened with the fingers; 2) a container and its airtight closure lid by the pressure that is opened with the fingers and replace of the sunken graphed lid. The invention prevents a sunken lid, such as an aluminum beverage can, from accumulating dirt in transport and storage. It also improves its aesthetics and can be used as diffusion media. The lid is installed by the beverage or food manufacturer.

0 State of the Art

Metal containers such as the congratulated aluminum can closes by tapping the lid onto the container, which creates a sunken cover where dirt accumulates that makes contact with the product when draining or drinking. This makes it prone to contaminate the product and the consumer, which caused death. The invention proposes an airtight lid that protects dirt from sunken closure containers. Although the proposed cap is of low cost, it is additional as can is used at this time. The invention furthermore proposes a modified container which is hermetically closed by a lid derived from it first, which is snap-closed and opened without tools. The invention can be used with current containers, can be made and placed with the same machines, reduces costs and avoids contamination.

It is an object of the invention to provide a hermetic protective cap on top of the sunken caps of the food and drink containers, pressurized after filling, which is opened without tools and closes the container after opening. This cover can be embossed and has a space for advertising insertion.

A second object of the invention is to provide a container that can be hermetically sealed by a snap-on lid which can be opened without tools.

A third object of the invention is to provide a hermetically sealed closure cap, which is machined after the filling, which is opened without tools, covers the contaminated areas that make contact with the product while consuming and closes the container of the second object of the invention.

A fourth object of the invention is to provide an insert receptacle that can be housed in the cavity created in the preceding caps.

Current Technique Description

The closure by the graph requires space for the inner roll which leaves a sunken lid exposed to dirt and contamination which may disperse diseases. Although food and beverages are packaged by comassepsy manufacturers, it is lost during transportation and storage, which can be a consumer hazard. Despite the variety of arts, tinned food drink manufacturers do not have cheap and effective means to protect the exposed areas of the container. They use, for example, covered with aluminum foil, which are fragile and airtight (Kronseder, US2004134913). They also use plastic envelopes.

In the art there are several covers proposed to protect the container once it has been opened, to facilitate the consumption of the product or to protect it from external elements, such as CA2262341 which is fixed by pressure, but not designed for industrial use. (Reusable Beverage Can Cap, Robinson Kenton I). It also allows to insert a norecipiente thin disk. Telmon (US2004226951 Pressure-appIied Iid forcanned beverages) This lid can be opened by snapping a tongue and includes break lines indicating yes the can has been opened.

The invention differs from the above in several respects. For example, this invention in addition to using two ring that creates a groove where it inserts into the rim of the container, its inner and outer sides have the shape of this rim to ensure hermeticity, essential for health protection, while maintaining the condition. just to be paid off with your fingers. The cover of the invention is airtight even though a part of this ring is broken for safety intentions. The covers of the invention are designed to be machine-placed by the food or food manufacturer, as most of the above are designed to be consumer-mounted. The aforementioned does not include a protruding ring or grooves for retaining inserts within the lid or a sealed receptacle accommodating in such a space. The space created between the protective cover and the surface of the container is variable and may take various forms depending on the intent of disclosure. The invention includes various safety mechanisms to show yes the lid has been opened.

Up to pressure closure systems, the art review shows Uhlig (US 4487326, Carbonate beverage package) which proposes a plastic snap closure for a specially designed container. Hancocks (EP761557, Wide-mouthed pressurable beverage container) proposes a screw closure that resists internal pressure within the container. The present invention differs from the proposals in that it is designed to be used in actual containers, and the proposed modifications are made and installed with the same engraving equipment.

Summary of the Invention

The airtight lid of containers such as the canned bottle is obtained with a design that takes advantage of some of its features. The inventive lid is essentially composed of a fixed protective cover (2) fixed to the closed container by the sunken surface (02), joined to an outer ring (5) that conforms exactly and fits the edge of the container (05). It also has an internal ring (4), that together with the outer ring (5) forms a solid (7) on the protective cover. The protective cover (2) extends downward to form a protective skirt (8) adapted to the shape of the container to be protected.

The lid is snap-fastened, without adhesive, and covers the top of the sides of the container that may be in contact with dirt on the consumer's lips. It also has a protruding ring (3) on the inside of the cover to ensure pressure in the groove. (3A) paincipient. The function of these three elements (3, 4 and 5) is to secure, without adhesives, the protective cap to the upper part of the container by acting individually or cooperating.

The cap also includes an inner safety ring (10) which is an extension of the inner side of the ring (5) and a hinge (9). Also includes stacked edges (6). The inner ring (4) has at least one projecting ring or groove (4B).

Comprising of the inner ring (5) the protective cap has an inner surface (5B) with shape and dimensions equal to those of the outer protruding ring (05B) to ensure hermetic sealing, with a plane (05B ") that holds it in position. Protective skirt (8) has a sealing edge (8B) which mates with edge 8A in the container.

It is possible to manufacture a cover that replaces the sink and prevent contamination. The container of the invention does not have a sunken surface (02) and its edge (05) protrudes on both sides (05A, 05B). This container is closed by a cap derived from the foregoing which on its edge (5) forms an inner surface (5A) with shape and dimensions that match those of the protruding contour on the inner side of the container (05A) to ensure airtight closure. The surface (2) is an inverted arc whose base (05A ') contacts the protruding (05A ") of the container and holds the lid in position. The container and its closure are made with the equipment used to make the aluminum can.

Brief Description Of Drawings

The invention is exemplified in the following drawings, which do not limit its scope: Figures 1 to 6 show the airtight protective cap, closed container and lid assembly, and a receptacle when in the container to protect it has its own lid.

Figures 7 to 10 show an open container and its airtight closure when the content generates internal pressure, as in carbonated beverages and beer. Although described, examples of containers and their hermetic closure are not shown when the contents do not generate internal pressure.

Figure 11 shows examples of the rollers for stapling the metal cap.

Detailed Description of the Invention

The following broad examples illustrate the invention but do not limit its scope:

Referring generally to FIGS. 1 to 6, the inventive closure is comprised of a protective cover (2) attached to the nipple closed by its sunken surface (02), joined to an outer ring (5) that exactly conforms to the nipple edge (05). It also has an inner ring (4) which joins with the outer ring (5) forms a groove (7) in the protective cap. The protective cover (2) extends downwards forming a protective skirt (8) adapted to the container shape to be protected, which has a closing edge (8B), also useful when the cover is installed.

The lid is pressed into a typical copper beverage can and seals the top and sides of the container that may be in contact with the product and the consumer lips. It also has a protruding ring (3) on the protective covered inlet which enters pressure into the recipient groove (3A). The function of these three elements (3, 4 and 5) is to secure the protective cap to the top of the container by acting individually or cooperating.

The lid also includes an inner safety ring (10) which is an extension of the inner side of the ring (5) and a hinge (9) to discard the lid along with the container. This safety ring can be located in several locations. includes stacked edges (6). The inner ring (4) has at least one protruding ring or groove (4B) to secure inserts in the gap (11) created between the sunken surface (02) and the protective cover (2), which also has the rings (3, 3B). These edges (3B, 4B) also serve to secure a sealed receptacle (1) that can be inserted into the opening (11).

The outer ring (5) has an inner surface (5B) with the same shape and dimensions as the outer protruding edge of the container (05B) to ensure airtight closure, plus a coupling plane (05B ") that retains it in position.

In this invention it is essential to achieve airtightness with precise adjustment to the protruding contours of the receiving edge and not just the plane that attaches the lid to the L hooks. This is used to support and retain, but not to seal, because it can be loosened as part inner ring safety.

The Graphic 1 shows the perspective and section of the datamp section with the protective cover (2), the protruding ring (3), the inner ring (4), the outer ring (5) and the groove (7), which exactly houses the rim of the container. (05) to ensure pressure cap and create airtight closure. It also shows the protective skirt (8) extending downwards taking the shape of the container to be protected. As indicated, the intent of these elements is to secure the protective cap to the top of the container, acting individually or in combination, to generate a substantially airtight seal and to cover the top and sides of the container to prevent contamination of these surfaces, which may be in contact with them. lips of the consumer or the product while drinking to the drain.

0 Graphics 1 also shows the inner safety ring 10 which detaches from the lid and shows without having been previously opened. There are several suitable sites for giving covers proper means of safety. This ring also serves to hold the lid to the container by means of the hinge (9) when the lid is discarded. This figure also shows tongue (12) when the current security system is used, which will be described later.

It also shows the stacking edge (6) which should preferably be discontinuous to prevent dirt and water from accumulating on the protective cover. The figure illustrates the outer ring (5) the inner surface (5B) with shape and dimensions that match those of the outer protruding edge (05B) of the container to ensure hermetic closure, and the engaging plane (05B ").

In the protected space (11) it may house the spreading insert held with the protruding ring or groove (4B) of the inner ring (4) or by 3B of the ring (3). In this invention this space is of variable height (15) since the protective cover (2) may have different heights with respect to the container edge, allowing for the insertion of inserts of various sizes. As mentioned, these blunt edges (3B, 4B) are also used to hold the embossed receptacle into the gap (11).

The Graphic 2 shows the perspective and section view of a typical metal beverage container with the opening tongue (01), the sunken lid (02), the groove (03) and the embroidery (05) with its inner side (05 A) and (05B) and its lower coupling planes (05A ") and (05B"), the inclined surface (08) and the container body (09).

The Graphic 3 shows the perspective and section view of a typical protective cap coupled to a typical container showing the elements described above, including the insert receptacle described below.

0 Graphics 4 shows the perspective and section section of a typical receptacle (1) for special inserts. Although the inserts may be placed directly into the protected space (11) and held by the edges or grooves (4B, 3B), some may be removed from the lid with this protection to be worn later. The sealed receptacle (1) is formed by a flat ring (16) for grasping the sealed cover (17) of all media and with appropriate material, by grooves or edges (14) that engage the edges or grooves (4B or 3B). It also has a base (19) and walls (20) that form the receptacle with its cavity (18). These elements have shapes that conform to the contour and the dimensions of each container and the height of the protective cover (2) so that the receptacle adopts the shape of the lid span (11).

0 Graphics 5 shows the perspective and section of the other options section of the protective cover shape (2), including a vault that allows it to be stacked (Figure 5a). However, these surfaces may vary in shape and size according to the diffusion needs. In its simplest form (Graph 5b), the non-inventive protective cap does not have the safety ring (10), the tab (12) for removing safety elements, the ring (3), the protective skirt (8), or the edges of the stacked (6). Others will be designed to create the maximum space without interfering with the dispensing machines, others without interfering with shafts, such as the Gráf dome. 5a, and others without limitation of form, in accordance with the objectives of diffusion. Similarly, the sealed receptacles will have shapes that fit into each lid design.

The Graphic 6 shows examples of lid applications such as carrying a plurality of containers (Graph 6a) with means (23) forming part of their manufacture and removable from the lids with cavities for introducing a handle (21, 22). An element in the collection (Graph 6 b) and an element for setting objects with the lid (Graph 6 c).

The Graphic 7 shows the perspective and section section of a typical open container, without the sunken surface (02), double graphed alkyl is created a new edge (050) which has two protruding, inner (05A) and outer (05B) sides and planes. (05A ", 05B") where a gasket can be accommodated (24 ') · Edge and surface geometry (05A, 05B) cooperate with correspondent in groove (070) of the inventive cap.

The gasket (24 ') whose function is to ensure the hermetic contact between the corresponding planes (05 "and 05B") at the cap (5 To and 5B'), it must be of the material that complies with the norms and may be a ring or perhaps more shaped. In practice, the embossing is made of a metal sheet, co-extruded on one or both sides with a polymer, as is done at this time, which gives more volume to the edge and more contact area. In this case the container will have a finish that avoids the direct contact of the lips with the metal. The projecting sides nor their downward length must be symmetrical, one side may be more protruding and broad than the other and have different geometries on their surfaces. What is essential is that they conform to their counterparts on the lid.

The Graphic 8 shows the perspective and section of the typical hermetic closure for the open container of the invention. This closure has the same elements of the protective cap already described (Figs. 1 to 6), to which are added: the groove (070) has the inner (5 A) and outer (5B) sides that conform to the inner and outer side (05 A) and (05B) the graphed edge of the container. The groove geometry (070) and its side surfaces (05A ', 5B') cooperate with their similarities (05 "and 05B") on the open container's graphed edge and create airtight closure. If the container is constructed of plastics or glass the inner and outer protuberances will form in the mold and will require the gasket only in the lid when it is metallic. In an example of the metal lid the preceding elements extend downwardly forming a slit (2A) and a plane (2B) which contacts the inner ring (05B ") on the edge. This plane has gasket (24 ') to ensure airtight seal. The closing cover (2') has an inverted arcuate shape (25), which by mechanical action and pressure of the content gas, creates airtight seal on the contact planes (2B, 05B "). As is well known in the art, the uncovered alloy, radios and rings reinforce the ability to withstand pressure and blunt. The concavity is covered with a lid (2E) which houses in the groove (2A), or catches on the surface (2C). You can have a tongue (2D) to remove it. This can also be obtained with pre notches in (2E).

The groove (070) engages at the edge (050) of the container and the graphite rollers press and print their shapes to the edge and lid (Graph. 7b) in order to complete the closure. The lid cover (070) may be slightly open before replacing it (Fig. 7c) and receiving the final pressure with the rollers. The edge of the plastic closures may also be impressed with heat or non-heat rollers with oulaser thermofusion and other techniques applied for similar intentions. For each case it will be decided how much pressure or heat is advisable, without preventing the removal of the lid with your fingers.

Many appropriate forms can be used. The Grafs. 9C, DeE show several possible shapes for a metal tampon. 0 Graphics 8B shows section and perspective cuts of a plastic lid extending internally downwardly until it reaches the conical portion of the container which also acts as the support background.

These edges (5A and 5B) also have safety loops (10) which rupture upon opening the lid as described to protect the integrity of the product and inserts. In addition to the safety of the inventive cap, it is possible to use external means known in the art, removed by means of a snap ring or eyelash (12). It is also feasible to pre-notch the sheet metal or break points on other materials to detach them from the lid and remain attached to the container. As is known in the art, a fixed point can be left as a hinge (9) and retaining the lid to the container.

In containers that withstand internal pressure, the vent cap can be of two classes:

1. Integrated and inner curved section and added outer flat surface, and

2. Integrated and external flat surface and internal curved section added.

In a second embodiment not shown, the flat surface (2 ') is an integral part of the lid and the gap (2A) is inside and receives the curved section (25) for the same effect as gas pressure. In both modalities the

The space (11) between the curved shape (25) and the flat surface (2E) may house inserts or a sealed receptacle (1).

The airtight cap of the invention meets the standards for this class of containers such as gas pressure, maintaining airtightness under different circumstances, normal mistreatment in transport and user, drops, daily differences in temperature and atmospheric pressure. It also provides appropriate safety to the integrity of the product and insert advertisers. There are several means to meet these standards: design and construction that transmits stress, with convexities, ring and radii, appropriate thickness and complement using heat, pressure and laser.

The Graphic 8 also show a valve (30) which is installed in the lid at a convenient location and whose function is to release gases in a controlled manner to reduce the pressure before opening without necessary, and to fill a previously closed container by modifying the current filling system.

The Graphic 9 shows the perspective and section of the assembled container and lid, with the characteristics already described.

One skilled in the art will know that this cap can be used for airtight closure when the container does not support internal gas pressure. In such cases the similar designs may decrease or suppress the curved shape, and the hermeticity is obtained by grasping and surface pressures described.

Construction

The protective cap is constructed separately with malleable material for each shape and size of container.

The closure cap is constructed separately from plastics, metals, composites, paperboard, synthetic paper. It can also be blistered in the can.

It is possible to combine aluminum container and lid, aluminum, plastic or glass container and plastic lid. The aluminum lid is constructed with the equipments and methods currently used to construct the double graphed sunken lid.

The open container of the invention and its closure make any container in use at this time. For example, aluminum nalata is sufficient to engrave a circular crown using the container tongue that is now used to secure the sunken lid. It is advisable that this tongue bends into the container and not outwards. It is made with the same current equipment and process, adapting the shape of the rollers. Figs. 11a, 11b.

Installation

The lid installs into the open container with the machine and process that are used at this time to attach the sunken lid. The pressure on the edge is made in a similar manner to the method and machine of the sinking lid graph to the container, giving the rollers the advisable geometric shape.

The process for producing and installing the new container and lid for an aluminum can is:

1. Attach an edge to the mouth of the container with protruding both sides,

2. Make the lid with geometry that conforms to the main container as suggested in the invention,

3. In a container with liquid put by the pressure cap in the container, or

4. Without container has been capped empty, fill with liquid using valve.

To consume

1. Verify that the container has not been previously opened

2. Open the can by pressing on the bottom edge of the skirt. If not necessary, before opening press the valve to relieve excessive gas pressure inside the container.

3. Remove advertising inserts or the receptacle.

4. From a wide mouth container, consume part of the contents and close again with hand pressure.

applications

The lid of the invention can be used on any open container in which a protruding edge can be constructed on both sides that allows repeating the natampa geometry. It can be used to close large diameter containers such as food and small diameter containers such as double, aluminum, wine glass, champagne, sparkling, beer and similar cans. Also for jars made of plastic that at this time use spiral caps. Using the appropriate materials it can be used for the bottled, heat-treated foods then defecated.

The invention may be used as a diffusion medium. Most of the materials used can be embossed, color printed and self-adhesive. The gap (11) is useful for inserting advertising objects, such as those used in mediumsimilar by advertising and promotion experts. The sealed receptacle extends these applications.
