Abstract

A lid for closing a single-use cup comprises a body, and, connected to said body, a locking rim. The locking rim is configured such as to have two open-ended arms having locking tabs arranged thereon for engagement with locking apertures provided in an annular wall; furthermore, the locking rim is connected to the body by a hinge joint. In a second embodiment of the lid, the locking rim and the body are configured as a single piece, elements of which are connected by a connecting strip having a straight folding groove, the open cavity of which is situated on the side opposite that of a seating surface of the body. A method for the leak-tight closure of a cup is also disclosed. The invention ensures that the process of closing a cup is as hygienic as possible under the circumstances by avoiding finger contact, which simultaneously reduces the amount of moving and positioning of the cup and the lid during the closure process.

DISPOSABLE SLIDING GLASS AND COVER FOR ITS IMPLEMENTATION (OPTIONS)

The present inventions relate to the construction of lids and the technology of hermetic sealing of disposable, usually paper or plastic cups filled with granular, pasty, flowing or liquid products, including hot drinks.

The lid on a disposable glass can be fixed differently. For example, due to the linear contact of the connected elements along their perimeter with the formation of tension, which provides the simplest fixation of the cover on the edge of the glass - see the description of the invention to the patent of the Russian Federation No 2345939 dated August 6, 2004, IPC B65D 51/24, B65D 43/08, B65D 81/00, publ. 10.02.2009, Bull. No 4, - FIG. 7 and 13. This cover is technologically advanced in manufacturing.

A different fixation is provided due to the congruence of the contact surface of the connected volumetric surfaces - see the description of the invention to US patent NW 8196772 of 04.17.2009, NCL. 220/669, IPC B65D 8/04, B65D 3/00, A47G 19/22, publ. 12.06.2012, - FIG. 5 and 7. Such a cap is difficult to manufacture.

As a result, the mentioned covers and methods of their fixation on the glasses do not provide reliable tightness of the connections.

There are other designs of lids for sealing disposable cups that solve the problem of ensuring the tightness of connections.

In particular, the known container lid, such as a paper container, for beverages, which is removably mounted on its open part, and containing the lower and upper parts, the upper part being in the assembled position can be rotated relative to the lower part to align them outlets, while the circumference-formed mounting shelf of the lower part of the lid interacts with the edge of the cup, the inner the side of which includes latching buttons designed to latch on to the edge of the cup, while adjacent latching buttons are separated from each other by ribs protruding from the outer side of the bottom of the lid [RF description N 2496698 of October 13, 2008 , IPC B65D 47/26, publ. 27.10. 2013, bul. Ns 30]. The lid is made with the possibility of re-closing and opening, and its design ensures impermeability to the liquid, even if a person drops the filled cup on the floor.

The disadvantage of the present lid is that the tightness of the cup closure is ensured by a set of snap-in buttons, which in total provide a very high quality connection with the lid with the hem. However, it is worth making an eccentric effort on one of the edges, as the cover is easily removed. Such an effort arises, as a rule, when a cup falls on the floor when the water hammer from the contents is not distributed (i.e. evenly) around the entire perimeter of the lid contact with the cup edge, but with concentration — to the local area — which means guaranteed disclosure of the compound and splashing out the contents.

In addition, the presence of a plurality of buttons and ribs with through outlets closed by the upper (movable) part of the lid implies uncontrolled collection of various contaminants and residues of the cup contents. All this suggests that the well-known lid is one-time, and this implies a significant amount of its disposal.

Packing a filled cup using the known lid of RF patent No 2496698 includes placing the cup on the table, covering its body with the fingers of one hand, installing the tilted lid on the edge of the glass with the other hand to ensure their initial contact and smoothly lowering the upturned part of the lid until fully closed contact around the perimeter of the edge.

Subsequent removal of the lid from the edge of the cup, if necessary, is carried out in the reverse order of the process. whipping - with the application of a concentrated force to one edge of the cover.

The disadvantage of this technology is that in the process of capping the cup and removing the lid, an eccentric application of considerable effort is applied, which leads to the appearance of an overturning moment on the cup. Insufficiently strong and insufficiently reliable retention of a filled cup, in the absence of appropriate skills, can lead to its tilting. Of course, this applies to ordinary consumers and is in no way connected with the professional skills of catering workers.

The closest set of essential features and achieved technical result is an adapter cover for a one-time glass with flanging (side) running around its open end, allowing the child to drink without fear of spilling the contents. The lid has an annular cuff associated with its body (the so-called locking rim), which supports the glass, engaging the lower part of its flanging. The body of the lid is removably engaged with the cuff and has an annular flange (so-called seating surface) to rest against the inner wall of the glass when the lid engages with the annular cuff, which occurs by an elastic snap of the connection being created, with the formation in the glass of the seal for the fluid [Description of the invention to US patent Ns 7156253 from 17.03.2003, NCL. 220/375, IPC A47G 19/22 B65D 55/16, publ. January 2, 2007].

Considering the design of the elastic connection of the lid with the cuff, it can be assumed with confidence that the material of the lid is a special, rather expensive rubber, otherwise it is impossible to ensure the return angles of the structural elements of a complex spatial detail when casting it. Such a design of the lid is quite reliable, however, high precision of the casting is required here, all the same, the possibility of uniform deformation of the screening with an elastic-resistant ring cuff or even its local one is not guaranteed. crumpling in the formation of compounds, as rubber, it is quite soft and elastic material. The same can happen in the event of a change in the size of a wide range of disposable paper cups. Thus, the tightness of the lid on the glass is ensured by friction forces, strict compliance of the lid with the size of the glass and further due to their qualified assembly, which is difficult for the average consumer to provide. And the absence of a lock joint in the contact zone of the lid elements can lead to their automatic opening from uncontrolled external influences, such as water hammering of the contents from the glass falling on the floor. The situation is aggravated if condensate has formed during the capping process on the surfaces of the lid elements to be joined, which performs the function of lubrication in the joint. Since parts of the product are connected by an elastic bridge, when the glass is closed, it tends to open the lid.

In addition, the molding of food rubber is an expensive and poorly automated process, its products are short-lived, therefore, these products are rarely used in everyday life.

Capping the filled glass using the known lid of US Pat. No. 7156253 includes orientation of the lid and releasing the annular cuff for the passage of the lower part of the glass, which is held with one hand, passed through the opening of the cuff and placed on the table. Using the fingers of two hands, the cuff is tightened to the screening and at the same time with the thumb of one hand the lid is pulled to its nearest section, after which the thumb of the second hand is placed on it and the connection of the nail phalanxes of the thumb is successively crimped.

The subsequent removal of the lid from the edge of the cup, if necessary, is carried out with the application of force to one edge of the lid to disengage the cuff and then in the reverse sequence of the capping process. The effort to overcome the friction forces in the ring joint can be significant, which, in combination with the soft from the high temperature of the contents of the wall of the glass, can lead to its uncontrolled deformation. And in the case of a filled glass, this will inevitably lead to splashing the contents on the table, on your knees, etc. In addition, when a lid is used by an ordinary consumer, it is difficult to ensure the hygiene of the connection being created, since in the process of such an assembly, the fingers will involuntarily touch the contact surfaces, both of the lid and of the glass.

The problem to be solved by inventions and the technical result achieved is to create a universal cover for hygienic and hermetic closure of disposable cups with flanging of several types, technological in manufacturing, simple and reliable during installation on the glass.

In addition, it provides the possibility of subsequent removal of the cover from the glass without losing its consumer properties and reuse in other glasses.

To solve the task and achieve the claimed technical result in the first version of the lid for a sealed lid of a disposable cup with flanging, including a housing with a seating surface and an outer overlap and a fixing rim connected to the housing, made with a fixed fixation on the housing with the formation of a closed cavity to accommodate the flanging of the glass, the housing contains on its lateral surface an open annular cavity with an annular wall on which they are located, with less In a measure, two fixing holes, the fixing rim are made to form two open elastic branches, on which the fixing protrusions are arranged to interact with the fixing holes of the ring wall, while the fixing rim is connected to the body by means of a hinge joint.

To solve the task and achieve the stated technical result in the method of sealing one-time tumbler with flanging, including installing the lid on its open part and its tight fixation using the flanging of the glass, the lid is made according to either of the two described above implementation, at the same time, put the glass on a hard surface, and after installing the lid on its open part, the lid is pressed to prevent the glass from tipping over, the elastic branches of the fixing rim follow single or simultaneously at the outer wall of the glass and lead to it with subsequent coverage, after which the elastic branches by their further rotation are fixed in the cavity of the annular wall of the lid by the interaction of the fixing projections of the fixing rim with the fixing holes of the annular wall with simultaneous deformation of the flanging of the glass, as a result, the seating surface comes into close contact with the inner surface of the wall of the glass, ensuring guaranteed tightness of the connection waiting for them.

It should be noted that the term _“ hermetic closure _” should be understood to mean the case when the lid-cup connection being created ensures reliable tightness of the assembly until the moment of forced destruction of the disposable cup as the weakest element of the mechanical joint.

The term "creasing" (groove) is formed from it. biegen - to bend, bend, bend, turn, bend, bend, make bend (widely known in the printing industry, where it means to extrude bending lines, so-called creasing). According to the text of the present description, it means a special constructive connection of the elements of the cover with the aim of their subsequent, including repeated, bending without breaking, ensuring a strong mechanical connection.

A lid 1 for hermetic sealing of a disposable cup 2 with the most common round 3 or flat 4 flanging in the first embodiment includes a housing 5 with a seating surface 6 and an outer overlap 7 and a fixing flange 8 connected to the housing 5, which can be fixedly fixed on the housing 5 with the formation of a cavity 9 closed over the cross section to accommodate the flange 3 or the flange 4 cups 2, WHILE THE CASE 5 contains on its side surface an open annular cavity 10 with an annular wall 1 1, on which olozheny at least two fiksi- ruyugtsih holes 12, the locking ring 8 is made of open to form two elastic branches 13 and 14 on which are arranged, for example, uniform locking tabs 15 for interaction with locking holes 12 of the annular wall 11, while the locking rim 8 is connected to the housing 5 by means of a swivel 16.

In addition, the hinged connection 16 of the locking rim 8 with the body 5, the locking protrusions 15 of the open elastic branches 13 and 14 of the locking rim 8 and the fixing holes 12 of the ring wall 11 are assembled for tight sealing, uniformly spaced around the circumference of the seating surface 6 of the body 5, with This elastic branches 13 and 14 of the locking rim 8 provided with stops 17 for engagement with the edge 18 of the annular wall 11 of the housing 5.

The number of fixing protrusions 15 on the open elastic branches 13 and 14 of the fixing rim 8 must be even - two, four, etc. Such a number can easily be evenly distributed on elastic branches 13 and 14 and, accordingly, to ensure uniform deformation of flanging 3 or 4 along the perimeter of the edge of cup 2, and, consequently, to ensure greater reliability of the joint to be sealed.

The outer overlap 7 of the housing 5 can be made deaf (conventionally shown in Fig. 13-21), including transparent, and can also be provided with a hole 19 for extracting the contents of the tumbler 2 (shown conventionally due to the variety of typical constructive and / or at least one hole 20 for the communication of the cavity of glass 2 with the atmosphere.

A lid 1 for hermetic sealing of a disposable cup 2 with the same most common flanging 3 or 4 according to the second variant also includes a housing 5 with a seating surface 6 and an outer overlap 7 and a fixing clamp 8 connected to the housing 5, which can be fixedly fixed on the housing 5 with the formation of a cavity 9 closed in cross section to accommodate the bead 3 or flanging 4 cups 2, WHEN THIS, the housing 5 contains on its lateral surface an open annular cavity 10 with an annulus A second wall 11 on which at least two fixing holes 12 are located, the fixing rim 8 is made to form two open elastic branches 13 and 14 on which, for example, unified fixing lugs 15 are located to interact with fixing holes 12 of the annular wall 11, and the fixing rim 8 with the body 5 is made as a single part, the fragments of which are connected by a jumper 21 to the rectilinear bead groove 22, the open cavity of which is made from the side opposite to the arrangement sedimentary surface 6 of the housing 5 (and / or by the location of the locking projections 15 fiksiru- guide rim 8).

The bending connection is the same jumper 21, - of the fixing rim 8 with the body 5, the locking protrusions 15 of the open arms of the fixing rim 8 and the fixing holes 12 of the ring wall 11 in the form assembled for hermetic sealing are evenly spaced around the circumference of the seating surface of the body.

Otherwise, the design of the second variant of the cover is similar to the first variant.

The method of hermetic sealing of a disposable cup 2 with flare 3 or flare 4 involves installing cover 1 on the open part of cup 2 and its tight fixation using taps 3 or 4.

Despite the fact that lid 1 can be implemented in two versions, the capping process is unified - glass 2 is placed on a hard surface, for example, a table top, and after installing cover 1 on the open part of glass 2 it is pressed to prevent tipping glass 2 , the elastic branches 13 and 14 of the fixing rim 8 sequentially or simultaneously lead to the outer wall of the beaker 2 and wind up on it with the subsequent coverage, after which the elastic branches 13 and 14 are fixed on the annular wall 11 of the cover by their further rotation 1 on its periphery at the same time by deformation of flanging 3 and 4 - by elastic folding of flanging 3 or by elastic bending of flanging 4.

The flare 3 or 4 cups 2 deform in a closed cavity 9 at the same time around the perimeter of the annular cavity 10 or, in extreme cases, in the place of the hinge / bead joint of the fixing rim 8 with the body 5 and fixing points of the projections 15 of the elastic branches

13 and 14 of the fixing rim 8 with the fixing holes 12 of the annular wall 11 (at three “points _” ). Thus, the wall of the cup 2, literally, is tightened on the seating surface 6 of the housing 5, ensuring guaranteed tightness of the connection.

It was established experimentally that when closing the paper cup 2, lid 1 should be installed with the combination of the hinged / scoreboard joint with its longitudinal overlapping seam. This is due to the fact that when consumed from such a glass of 2 hot or warm drinks with an _“ incorrect _” orientation due to the difference in wall thickness in the overlap joint, capillary fluid leakage is not excluded. When capping polymer glasses 2, no additional features were revealed.

The obtained connection of the cup 2 with the lid 1 according to any of the variants implies the possibility of their subsequent disassembling in a sequence opposite to the capping process, while the elastic branches 13 and

14 of the fixing rim 8 are simultaneously or sequentially removed from the fixed engagement with the annular wall 11 of the lid 1, by removing the locking protrusions 15 of the elastic branches 13 and 14 from the engagement with the corresponding fixing holes 12 by exposing them to the nail phalanxes of the fingers.

Thus, the design of the lid 1, if necessary, provides the possibility of both capping the cup 2 and the subsequent removal, i.e. installation- disassembly (assembly-disassembly) of the connection.

Let us analyze the essential features of inventions.

The separation of the locking rim 8 into two elastic branches 13 and 14 allows you to ensure the maximum possible hygienicity of the capping of glass 2 in such cases - flanging 3 or 4 does not in any way come into contact with the fingers. The number of movements and orientations of the cup 2 and the lid 1 is reduced when the capping process is carried out, which simplifies it as a whole.

The fit of the locking projections 15 of the elastic branches 13 and 14 of the locking rim 8 into the fixing holes 12 of the annular wall 11 provides a reliable locking connection with a guaranteed tension of the cup 2 on the seating surface 6 of the housing 5 due to the directional deformation of the flanges 3 or 4 throughout the perimeter of the annular cavity 10 of the housing 5 of the cover 1 or at least in local zones of the hinged / folding (16/21) connection of the elements of the cover 1 and the areas of fixing the projections 15 in the holes 12 of the annular wall 11 of the housing 5, if the rigidity flanging 3 or 4 cups 2 for a number of reasons will exceed the stiffness of the elastic branches 13 and 14 of the fixing rim 8. The latter is facilitated by the uniform distribution of the power elements around the circumference of the seating surface 6 of the lid 1.

Elastic branches 13 and 14 of the locking rim 8 are provided with stops 17 for engagement with the edge 18 of the annular wall 11 of the housing 5. This ensures the accuracy and completeness of the assembly when sealing the cup 2, and also facilitates the subsequent disassembly of the created connection.

All of the above excludes the spontaneous opening of the joint without its mechanical destruction, even in cases of involuntary dropping of the sealed cup 2, for example, on the floor, with the occurrence of a hydraulic shock directed towards the external overlap 7. The same applies to the use of cup 2 with a lid by 1 small children, who cannot always control their use for their intended purpose.

Vigovochny connection through a jumper 21 of the fixing rim 8 with the housing 5 allows you to ensure high manufacturability of the manufacturing of the cover 1, as a single part at minimum cost. The hinge 16 of the locking rim 8 with the housing 5 is less technologically advanced, since it requires the manufacture of at least two independent parts and their subsequent assembly. However, in this case, for the manufacture of parts, you can use different materials, for example, the volumetric case 5 can be made of expensive food-grade polymer, and the locking rim 8 can be made of harder, more durable, less expensive and not necessarily food.

In addition, the articulated version is much more durable than the version with the creasing groove 22. At the same time, the articulated connection 16 provides hundreds of opening-closing cycles, whereas the version with the creasing groove 22 provides only dozens of cycles.

In all cases, cover 1 can be reused. As a rule, once purchased lid 1 (with or without a glass of 2) can later be reused if proper hygiene requirements are observed. Of course, this does not apply to the catering system, except for the cases when, when buying a glass of 2 with a drink, the buyer, for a number of reasons, asks to be capped with his own lid 1. As you know, using reusable utensils reduces environmental the load on the nature due to the reduction of utilization volumes, in this case, covers 1.

The versatility of the lid 1 is ensured by the fact that it can close paper and plastic cups 2 with flanging of several types, mainly round - 3 and flat, conditionally horizontal - 4.

The tightness of paper cups 2 with round flanging 3 is ensured by the fact that the lid 1 creates practically two sealing areas - a forced fit of the inner wall of the glass 2 on the seating surface 6 of the body 5 of the lid 1 and the forced deformation of the flanging 3 in the annular cavity 10 by elastic branches 13 and 14 fixing rim 8, i.e. in a cavity closed in cross section 9.

Tightness of polymeric glasses with flat conditionally tonal flanging 4 is ensured only by the fact that the cover 1 creates only one sealing area - the forced tension of the inner wall of the glass 2 on the landing surface 6 of the housing 5 of the cover 1.

In addition, the versatility of cover 1 is ensured by the fact that with minimal modifications it can be used for various purposes. For example, the outer cover 7 of the housing 5 may be made deaf, transparent, provided with a hole 19 for extracting the contents of the cup 2, a hole 20 for communicating the cavity of the cup 2 with the atmosphere, etc.

Making the outer cover 7 of the housing 5 of the lid 1 deaf, including transparent, allows it to be used, for example, for sealing various loose, conditionally free-flowing and other products, such as convenience food, convenience products, cereals, etc. - especially small batches. This does not require the use of specialized process lines designed for large production volumes.

The outer cover 7 of the housing 5 can be provided with an opening 19 for extracting and consuming the flowable, liquid, including hot contents of the bowl 2, directly through a special closing opening 19 or using auxiliary means, for example, straws and other .

In the construction of the overlap 7, as a rule, one or several openings 20 can be provided for communicating the cavity of the cup 2 with the atmosphere, which is important for equalizing temperatures and, accordingly, pressures, for example, as a result of cooling / heating the contents of the cup 2. It should be borne in mind that the accidental, unconscious spilling of liquid from a sealed glass 2 through a small hole 20 located on the periphery of the outer overlap 7 does not reduce the overall reliability of the seal sealed. capacity. The advantages of the method of closure of a disposable cup 2 with screening 3 or 4 and the possibility of implementing the declared technical result are directly related to the design features of the two variants of the lids 1.

To seal glass 1, including hot and sweet content, it is simply placed on a hard surface such as a table. From the stack of lids 1, take the top one, orient it with the landing surface 6 downwards and place it on the open part of the cup 2.

Next, the lid 1 is lightly pressed with the thumbs of both hands to prevent the glass 2 from tipping over. Elastic branches 13 and 14 of the fixing rim 8 sequentially or simultaneously bring free fingers to the outer walls of the glass 2 and lead onto it with subsequent coverage, after which the elastic branches 13 and 14 in the composition of the fixing rim 8 by their further rotation by means of a hinged 16 or creasing - using jumper 21, - the connection is fixed on the annular wall 1 1 of the cover 1 along its perimeter until it touches pore 17 both elastic branches 13 and 14 with the edge 18 of the annular wall 11 of the housing 5, i.e. until click. The flange 3 or 4 is deformed in the lid 9, closed over the cross section, around the perimeter of the rim of the glass 2 or in the characteristic zones - at the hinge 16 or scoring connection of the fixing rim 8 with the body 5 and fixation points of the lugs 15 of the fixing rim 8 s fixing holes 12 of the annular wall 11.

As mentioned above, the number of fixing protrusions 15 on the open elastic branches 13 and 14 of the fixing rim 8 can be two, four, etc. It should be borne in mind that a large number of fixing protrusions 15, while ensuring the reliability of the sealable joint, at the same time complicates the process of cup 2 and, especially, the process of further disassembling and removing cover 1.

The implementation of the invention consider the following examples: Example 1. Sealing a disposable paper cup 2 with a round flanging 3 filled with a hot liquid drink, a lid 1 made according to the first embodiment.

A special feature of sealing is the use of the cover 1 of a special design - its body 5 and the fixing rim 8 are independent parts that are interconnected by means of a hinge 16.

In the initial state, the body 5 of the lid 1 and the locking rim 8 are deployed horizontally, stacked one on another and placed in a hygienic package. The outer cover 7 of the housing 5 is equipped with, for example, an ergonomic protrusion (conventionally not shown) with a opening opening to consume the beverage.

Paper cup 2 is filled with hot drink and put on the table. The top cover 1 is taken from the stack and put on by the body 5 on the open part of the glass 2. The lid 1 is pressed to prevent the glass 2 from tipping over, the elastic branches 13 and 14 of the fixing rim 8 pivotally connected to the body 5 are sequentially or simultaneously fed to the outer wall of the cup 2 and lead to it with the subsequent coverage, after which the elastic branches 13 and 14 by their further turning and turning up to 180 ° are fixed on the ring wall 11 of the cover 1 along its perimeter. At the same time, characteristic clicks are heard. This means that the locking protrusions 15 have interacted with the locking holes 12 of the annular wall 11. There has been a deformation of the round flanging 3 cups 2 in the housing 5 closed over the cross section of the annular cavity 9 of the housing 5, the seating surface 6 of which came into close contact with the inner wall of the glass 2. How As a rule, the tight contact of the seating surface 6 of the housing 5 with the inner wall of the cup 2 ensures the tightness of the connection; howl cavity 10 of the body 5 but is increased an additional sealing cover glass-compound (conventionally iz bytochnaya function - parametric reserve).

Corked glass 2 can be taken away with you for further use of the drink. Accidental tilting of the glass 2 and even its fall on the floor do not allow its contents to pour out.

Further, comfortably sitting, for example, in a car seat, an opening is released on the outer cover 7 of the housing 5 of the cover 1. The contents of the glass is used for its intended purpose.

At the end of the consumption process, cover 1 can be removed from glass 2, which is thrown away for further disposal, cover 1 can also be thrown away, but can be taken away with you. After the hygienic treatment, it can be repeatedly reused, for example, when you buy a hot drink the next time, you can use your own “free” lid 1. Also, for example, you can use the real lid 1 to feed your child without fear that he will spill the drink, while the design of the lid 1 and its strong connection with glass 2 will not allow the child to subject the tight joint to uncontrolled disassembly.

Example 2. Sealing a disposable paper cup 2 with a round flanging 3 filled with a liquid hot drink, a lid 1 made according to the second variant.

A special feature of sealing is the use of the lid 1 of a special design - its body 5 and the fixing rim 8 are interconnected by means of a jumper 21 with a rectilinear scoring groove 22 and constitute a single piece.

In the initial state, the body 5 of the cover 1 and the locking rim 8, like Example 1, are deployed horizontally, stacked on top of each other and arranged in a hygienic package. The outer overlap 7 of the housing 5 is also equipped, for example, with an ergonomic projection with an opening opening for the consumption of bulk.

Paper cup 2 is filled with hot drink and put on the table. From the stack, take the top cover 1 and put it on the body 5 on the covered part of the cup 2. The lid 1 is pressed to prevent the cup 2 from tipping over, the elastic branches 13 and 14 of the fixing rim 8, which are connected to the body 5 by the jumper 21, are successively or simultaneously fed to the outer wall of the cup 2 and lead to it with the subsequent coverage, after which the elastic branches 13 and 14, by their further turning and turning up to 180 °, are fixed on the annular wall 1 1 of the lid along its perimeter.

Then everything happens as in Example 1.

Example 3. Sealing disposable paper cups 2 with round flanging 3 filled with bulk product.

With the release of small batches of some products, such as breakfast cereals, fast food, etc., there is a problem with their packaging in a convenient container and the subsequent hermetic closure. The cost of sealing a limited, small container with the use of industrial specialized equipment significantly and disproportionately increases the cost of the product. To solve this problem, you can use the standard mass cap 1 in the first or second embodiment. A feature of the design of such covers 1 is that the external overlap of 7 of their housings 5 is made deaf and including transparent.

Sealing glasses 2 is similar to Example 1 and Example 2 with the only difference that paper glasses 2 and / or lids 1 are pre-labeled with relevant service information, and sealed containers (glasses 2) with products come in, for example, the distribution network .

It is possible to reuse these covers 1 in the first and second versions for sealing various products on other paper cups 2 with round flanging 3.

Example 4. Sealing a disposable polymer cup 2 with a flat, conventionally horizontal flanging 4. This glass 1 can be used for bottling and for placing other products in them like Examples 1-3.

A special feature of sealing such a container is that sealing occurs only through the creation of tight contact in the connection between the attachment surface b of case 5 and the inner wall of glass 2. The deformation of a flat, conditionally horizontal flange 4 ensures close contact of the mating surfaces, but does not participate in the creation of additional hermetic connections is similar to the round flap of 3 paper cups 2. Nevertheless, the stated technical result is guaranteed to be guaranteed.

In all cases, lids 1 with previously purchased corked glasses 2 can be reused for their intended purpose on any suitable container in compliance with all hygiene requirements.

As a result of the use of inventions, universal lids were created for the hygienic and hermetic closure of disposable cups with flanging of several types, technologically advanced in manufacture, simple and reliable during installation on the glass. There was a possibility of subsequent removal of the lid from the glass without losing its consumer properties and reuse in other glasses.
