Description

"PROVISION INTRODUCED IN. STOCKED FOR EARLY CONSERVATION CONTAINER".

Application Field

The present utility model patent "PROVISION INTRODUCED INTO A SEALED OR SIMILAR THREADED COVER" relates to an improvement introduced in an occlusion cap used in canned food containers such as vitreous containers commonly used to contain palm hearts, pickles, olives, baby foods known as "babyfood", among others, whose construction system is comprised of two separate closing elements, namely a discoid-stopper device with sealing attributes and a threaded mechanical pressure ring element and a withdrawal device of said discoid device.

The object of the present patent was conceived with intelligent and original constructive disposition, aiming to improve the organic integrity of the products contained in the vitreous containers or metal cans introducing in the sealing element devices that guarantee greater exhaustion of the internal oxygen during its extraction process, known as "nomadic technique". vent ", which ensures a higher vacuum during food processing as well as an annular projection on the internal perimeter of the threaded annular element, which in addition to functioning as an integral part of the valve, avoids the accumulation of water sludge from the processing tank and the formation of oxide. iron (rust) in the screw region.

Thus, in the present patent application, there is an improvement in the canned food occlusion cap, which belongs to the field of food packaging articles, whose occlusion technique involves an annular shaped overcap, which compresses a back cap of disk-shaped, against the nozzle of the container, whose constructivity allows to remove the internal air of the container, more efficiently promoting a seal much above the relevant norm.

It is a further object of the present application to provide an occlusion cap containing an exhaust valve, which is fixed to the respective container by over-stripping technique of a polymeric ring which supports the autoclaving temperature on a back cover intended for containment packaging. preserves food products or others, with low costs for their industrial feasibility, adding requirements of robustness, airtightness, impermeability, user safety, greater vacuum and reliability, reaffirming its utility practicality, giving the industrial or final consumer of this input, additional freedom and choice in similar market, offering numerous possibilities and benefits, becoming a specific model of great expectation for this sector market.

Disposition History

As is well known, business and the food industry have been presenting their products confined in transparent packaging with the intent to allow consumers to view content.

Canned food containers such as palm hearts, pickles, olives, among others of the genus are made up of vitreous material, which restrict the technologies for the application of the top and sealing elements due to the physical characteristics of the material, due to thermal or breakage.

Over the years, the technician has developed a lid with simplified withdrawal system, which consists of a ring-shaped overcap, which compresses a disk-shaped lid, responsible for the length and sealing of the container.

The overcap allows the initial opening or vacuum break only by turning it counterclockwise.

Poor points of the prior art

The traditional packaging offered in the market satisfactorily meets the regulatory, commercial and safety requirements, effectively sealing, sealing and exposing the contained product, however, it is observed in practice that users, especially those less concerned with the use of brute force, such as women and women. children, face difficulties when opening the package, and this is revealed by the action of the vacuum added to the friction of its sealing layer against the mouth of the recipient, this makes the end consumer use sharp and perforating to break the vacuum, formed in the process. sterilization or pasteurization, thus causing accidents with such objects.

The commercially available simplified withdrawal cap, which consists of a ring-shaped overcap and compresses a disc against the container mouth, does not satisfactorily fulfill its intended function, as it has been observed in practice that despite having an opening simplified its constructiveness does not allow the adequate vacuum to be obtained, as well as in some cases it allows the entrance of the external liquid during the food sterilization or pasteurization process.

Layout Summary

In order to solve the observed drawbacks, the inventor devised a simplified opening and cap sealing system with a ring-shaped overcap and a sealing disc, which solves the problem presented and technically increased the design. It also provides better performance in the "vent" oxygen exhaustion procedure, also considering the need for occluding the patient to consume the product on subsequent occasions.

It was by thinking of the reported drawbacks and possible improvements that the inventor, with well-known sectoral technical knowledge, devised, designed, and developed the object of the present patent, "Introduced Threaded Container Arrangement", which designs an edestrave occlusion-cap system intended for use. canned or other food-containing containers containing a solid structure, characterized in that it contains a sealing metal disc located below a polymeric rim which tightens it against the container nozzle and completely seals the contained food container.

The threaded polymeric ring device, or overcap, which partially covers the metal-clamping disc on its periphery is constructed of polymeric material having a free central plane in the absence of material, where the perimeter rim has contact interface with canned container, outlined by the region of the threads and an annular projection compresses the metal disc against the recipient nozzle.

The metal buffering disk has a centrally planned structure and forms a separation interface between the internal volume of the canning container and the external medium, having all the barriers required for greater preservation of the potted product, and in its surrounding edge it has a concave profile with a recessed recess. an immediately preceding portion forming a channel into which it seals below the nozzle of the container. The sealing material is applied to said channel by interspersing the mouth of the container and the lid.

In addition, the present cover has a valve whose operation is similar to a check valve that allows the oxygen to escape when heated to a certain temperature and automatically closes when this pressure decreases, thus not allowing external fluids to enter and consequently avoiding contamination. as well as external liquids.

Said valve provides greater efficiency in the removal of oxygen or process known in the technical environment as "vent", causing the bottled product to be in a lower pressure environment, that is, the inside of the container is more vacuum than the occluded containers with similar caps. in the referring market.

A higher vacuum gives the conserved food a longer shelf life.

Accordingly, the present patent, "INSERTED IN A THREADED COIL FOR A CONSONSIBLE OR SIMILAR CONTAINER" was intended to obtain an occlusion system of glass containers and plastic pots, intended for canned or other products, conveniently developed and engineered to enable the user to have impaired his or her own. use, performing its functions with efficiency and simplicity, demonstrating unmatched practicality and versatility, incorporating peculiar features, and preventing the final consumer from using sharp or piercing tools to proceed with its opening, thus contributing to the reduction of domestic accidents caused by the use of such tools.

The screw cap now presented has the following advantages over the caps found in the relevant market:

- Easy opening.

- Higher vacuum, thus greater safety for the producer and user.

- Safety for the user on opening.

- Dispensing of sharp and piercing objects.

- There is no oxidation because there is no contact with metal departments in friction with the glass.

- Less dirt.

- Does not retain liquids between the cap and the buffer disc due to the extraction ring being sectioned.

- Do not dust because it is full thread.

Its innovative concept allows for a constructive arrangement with excellent level of functionality, being developed according to the most modern techniques, thus allowing a simplified use.

It is to be understood, therefore, that the valve system with valve function and the disengaging lever of the buffering disc is simple in its constructivity and therefore easily achievable, obtaining excellent practical and functional results, incorporating an innovative and effective technique. The plastic ring, or overcap, contains a device which, when unscrewed, forces the tampon disc ferrule to disengage from the nozzle, more precisely raises the end of the tampon disc element and thereby effecting a broken vacuum of the container, allowing a simplified opening.

Detailed Description of Incorporation

According to what the above figures illustrate as "PROVISION INTRODUCED THREADED BULK CONTAINER" refers to a simplified closure, sealing and opening system for canned or other food product containers called capped to container (1), the structure of which is comprised of a threaded ring-shaped overcap (2), contains a tamponade disc (3) for lower allocated occlusion, which is compressed against the top of the canister (4) nozzle (5) ) completely sealing the contained food.

The overcap (2) is comprised of a polymeric material construct having the central plane (6) free and absent of material, the inner edge of which has a downward perpendicular annular projection defined as a control ring (7) and a further projection thereon. also referred to as the anchor ring (8), but with a larger linear dimension in relation to the control ring (7), the end of the rim is constituted by a wall that protrudes downwards in ninety degrees, conforming to a surrounding face (9). Top and sharp outer face has a smooth finish.

The only contact interface of the overcap (2) with the buffer disc (3) is the retaining ring (8), which exerts a downward force against its surface by pressing it onto the top of the nozzle (4). when threaded into the nozzle.

The overcap (2) has an inner elliptical thread (10) on its inner side (9) which is discontinued at its full height, which allows threading with the final thread of the thread and above that thread is provided an extractor ring ( 11) or barb with shallow entry angle profile, but no exit angle allowing coupling of the counter-disc (3) to the overcap (2) by its perimeter protruding edge defined as ferrule (12).

The tamponade disc (3) has a discoid format with the flat central structure (6) and forms a separation interface between the internal volume of the canning container (5) and the external environment, and its surrounding edge has a fold called ferrule ( 12), which is supported below by the extractor ring (11) and within an immediate radius of the front an inverted U-shaped profile forming a channel (13) where the sealing material (14) is deposited, which is shaped by the nozzle (4) ) and in a more internal radius there is provided a concave region (15) with a "V" profile where the fixing ring support (8) is provided. Said puller ring (11) is segmented into four parts to allow the process tank tank to flow out of the screw region after processing the food, avoiding oxidation of the disc-bearing rim (3). The puller ring (11) has as a function of retaining the metallic disc in the overcap (2) and further limiting its movement against the container nozzle, its positioning allows to maintain a space between the upper face of the disc in the groove region (13) and the inner face of the overcap, defined as a working range (16). This working range (16) allows the buffer disc (3), when under high temperature and vacuum action, to move and work as a pressure cooker valve and respectively a check valve.

Another technical function of the puller ring (11) is to form a lever system to force the withdrawal or withdrawal of the buffer disc (3) that, when occluded, suffers the action of the internal vacuum or consequent pressure of the atmospheric column, which makes the opening operation of the package difficult. by the user.

The buffer disc (3) receives a sealing material (14) in the surrounding channel (13), which after drying has a higher hardness than conventional ones, which compensates for the deformation of its contact interface and the top of the nozzle (4) of the container. (5), which guarantees the technical efficiency of the packaging sealing system, even with a higher vacuum, and does not require re-tightening of the overcap (2) after oxygen extraction.

The sealing of the screw cap for the canning container (1) is effected by the action of the depression difference between the outside and the inside of the container, and by unscrewing the overcap (2) there is a vacuum break and opening of the package.

It is emphasized that the sealing ring formed by the sealing material (14) has a reduced area, being limited to the region in contact with the top of the nozzle (4), thus avoiding overexposure of the sealing material (14) to the product contained in the respective container (5). ).

The canned container screw cap (1) ensures effective mechanical or hand-operated threaded coupling, whose hermetic attribute prevents the entry or exit of gases, liquids and debris to the inside or outside of the package, and during the processing of the product the respective cap It allows the exhaustion of the oxygen inside the container, a process called "vent" (17), increasing the internal vacuum compared to conventional caps and during processing also does not occur the contamination of the processing water with the internal liquids or product.

Airtightness is guaranteed even after opening for consumption. The canned container lid (1) has hermetic and impermeable attributes, keeping the product contained in it free of moisture and deodor transitions even after the package has been opened for consumption.

In food processing, the "oxygen that exists inside the vitreous container, when heated, expands and forms a positive pressure forcing the tampon disc (3) outward. With this occurs the phenomenon called" vent "(17) which is the exhaustion of the oxygen, when the internal pressure decreases, it retracts and attracts the back cover.

The spring effect or vane movement caused by the buffer disc (3) due to the internal and external depression difference allows oxygen to escape, but due to the lid control system, it does not allow liquid to enter the heating tank or the doliquido outlet contained in the container (5).

The oxygen exhaust valve is based on the movement of the buffer disc (3), which is controlled in the contraction phase of the inner atmosphere by the extractor ring (11) and in the expansion by the control ring (7) and the working interval (16). .

The extracting ring (11) prevents the counter-disc (3) from being excessively compressed against the container nozzle (4) in the contraction phase of the internal atmosphere, preventing excessive deformation of the sealing material (14), allied with the sealing material. (14) Higher hardness dispenses with tightening the lid after vacuum formation.

The control ring (7) prevents excessive deformation of the bearing disc (3) during the expansion of the internal atmosphere and allows its rim to move away from the edge of the shell (4) of the container (5), occupying the gap at which time the gas contained in the container escapes through the momentarily formed space between the sealing material (14) and the nozzle top (4).

More precisely, the control ring (7) and the extracting ring (11) act as supports exerting exactly the opposite force of expansion and contraction by balancing the degassing outlet and not allowing contaminant water to enter the processing pipe into the container with the bottled product.

The retaining ring (8) is comprised of a polymeric flap advancing to the center of the overcap, in permanent contact with the packing disc (3); which prevents liquid from the processing tank from penetrating and soiling into the upper portion and the region between the metal disk and the plastic ring.

Said tab or retaining ring (8) also performs the important function of compressing the disc allowing vent to occur (17) without water entering the annealing tank and thereby preventing contamination of the brine or potted product. The metallic buffering disc (3) which is fixed by the extracting ring (11) has controlled mobility thus allowing oxygen to escape, thus ensuring a higher vacuum and consequently greater product warranty.

In occlusion of the container, prior to the heating process, the overcap (2) and the metal buffer (3) rotate as one piece.

After the oxygen has been removed, the metal-clamping disc (3) is firmly fixed to the nozzle (4) by the vacuum (5), and at its opening, initially only the ring rotates by ninety degrees, from which the ring puller (11) lifts the metal buffer disc (3), breaking the vacuum, causing it to rotate together.

Below are some of the technical characteristics obtained by the arrangement introduced in the screw cap, now presented:

• The lid in question does not dust off, unlike conventional lids that work with a fulcrum on the pot thread, it has full threading with stop at the end of the thread.

• The metal buffer disc (3) may be smooth or optionally contain a safety button. The function of this safety button is to enable the consumer to check if the product is packed in a vacuum container.

• The sealing material (14) is applied only to the channel (13) of the buffer disc (3) as much as necessary, unlike conventional caps having sealing all over its internal area, thus exposing the sealed product to the sealing material (14) to minimum, even this sanitary tendency.

• Cover surfaces in presentation are always smooth and polished to prevent dirt.

• The side of the overcap (2) is provided with anatomical ridges to facilitate its opening operation.

• The metal buffer disc (3) has a ferrule (12) facing the outside, aiming at:

- Isolate a possible oxidation of the leaf cutting area.

- Lock the metal buffer disc (3) in the inner extraction ring (11) in order to attach it to the overcap.

- It has an exact measurement for the metal buffering disk (3) to act as a valve, moving in the space left by the plastic part or working range (16).

The threaded container canning lid (1), now presented, also meets the specifications required for infant foods and can be used even in metal containers known as tin.

In the case of metal packaging or cans, it is important to emphasize that there is no metal friction, but plastic with metal, so there is no peeling of the protective layer of the can and consequently there is no metallic exposure and oxidation.

In glass packaging applications, because the ring is polymeric, the only place where atritomechanics occurs, there is no oxidation in the claw areas.

Thus, it can be seen from the above that the "ARRANGEMENT INTRODUCED IN THREADED COVER FOR CONSERVATIVE OR SIMILAR CONTAINER" hereinafter is characterized as a screw cap occlusion model that presents as we could evidence in function of the analyzes performed and the figures shown, There are innumerable differences over conventional models in the consumer market, as well as constructive and functional technical characteristics completely different from those pertinent to the technical state.

Because of the advantages it offers, as well as the truly innovative features that meet all the requirements of novelty and originality in the genre, this "MUSHROOM CONTAINER PROVISION" meets the necessary and sufficient conditions for the Model Privilege to meet. Utility.
