Description

The present invention relates to a closing can and a can with contents modified for use and re-closing if not all of the contents of the can have been drunk, but only part of it.

BACKGROUND OF THE INVENTION

The metal can for drinks, which is a system of two integral parts - the can body and the can cover, is one of the most popular types of packaging for storing and consuming drinks around the world. Consumers are happy to use this packaging because it is easy to handle, the quality of its material allows it to protect the contents well, and also thanks to many other useful characteristics.

Cans for drinks are very convenient both for home use and for use on the street. The use of such cans outside the home accounts for a significant percentage of their total use (for example, during travel, sporting events, etc.). In the latter case, the entire contents of the jar is not drunk immediately, the complete emptying of the jar occurs with several interruptions, so the entire contents of the jar can be drunk within one hour or even more. And here the shortcomings of metal cans are manifested, since the drinks contained in them are not originally intended for long-term storage in open form.

The possibility of re-closing the can is a very useful function not only to preserve the freshness of its contents after opening the can and partial consumption of the drink, but also to eliminate the possibility of contamination of the contents and insects getting into the open can after opening and until the can is completely emptied. The latter factor can lead to undesirable consequences for human health in connection with violations of hygiene requirements when using such packaging on the street.

Previously proposed technologies in this area involve opening the can from above, closing it with a lid on the same end side (see documents under number WO 97/36739 or WO 01/66431). The bottom (base) of the can has already been proposed for use as a closing part using an inwardly concave bottom (see document number WO 03/066455 and others). Cans with a bottom located at the top and a closing lid on the narrowing side are considered in document number DE 19802953, but there is a significant change in it - the convex bottom (upper part) and the increased height of the can, which leads to insufficient stability of the can during filling . You can fill these cans for drinks in the same way as bottles through the neck.

The purpose of the invention

The aim of the present invention is to satisfy the needs of the consumer, eliminate the disadvantages that are inherent in the "two-component" banks due to the inability to re-close them, creating a technology that allows re-closing the banks.

This invention will improve the possibility of using cans on the street, increase the time during which it is possible to consume the contents of the can, and allow the consumer to close the can every time not all the contents of the can are emptied, but part of it.

This invention provides the interaction of the various components of the can described in paragraphs 1-4 of the claims for a simple beverage cans, 27-30 for a composite can body. The following components are listed below:

a can body for storing liquid products, such as drinks;

can lid, optional;

tapering portion (neck) for pouring or drinking contents connected to the bottom of the can;

threaded cover for repeated closing;

additional sealing vessel, optional.

The present invention makes it possible to repeatedly close the can at the base of the can or can body, i.e. in the part opposite the can lid. The part of the jar that is not intended to be opened has a standard design with a tapering neck on the side surface or without it, as well as a protruding flange in the uppermost part of the can body.

The most common concave shape of the bottom of the can is replaced by a convex, the bottom is curved outward (in the axial direction). The domed shape, curved outward, is a shape with smooth lines that does not have transitional elements connecting the side surface with the base or neck of the can. The curvature of the convex bottom of the can does not change in directions, while it can vary in its absolute value from minimum to maximum, in the radial direction from the outer circle to the center. This "three-radius" geometry explains the vaulted shape of the bottom of the can.

A round hole located in the center of the base is a seat for the main element (holder), which is installed constantly and serves to carry out the procedure of multiple tight closing. After attachment, tight closure occurs on the outer circumference, which has a protruding horizontal collar, which allows the bank to remain stable on any horizontal flat surface, for example, on a conveyor, or on pallets of loaders, or on store shelves, or when banks are installed on the top covers of other cans etc.

The proposed method implies that beverage cans will be closed using a special closing device attached to the base of the can. A closing device can be installed at the can manufacturer before the can is filled. The device for filling the cans will work without changes, because it does not require any changes either in the design or in the technological operation of rolling the cans. After filling the can body through the completely open second end part, it is covered with a lid, then the can is rolled up to close and seal the can with the drink contained in it. The lid of the can (the “end part”) used to close it after filling does not have any “tongues” or other opening devices, so the jar does not have the so-called “lid for easy opening”; instead, it has an “end part” "Not intended to be opened (and therefore a lid that cannot be re-closed).

The device for repeatedly closing the can has a so-called neck (spout) for drinking (or emptying the can) and a lockable lid with thread. A cylindrical neck is installed above the hole, which is located in the center of the base of the can, which has a convex dome-shaped shape.

The most preferred embodiment is a threaded lid that matches the neck thread, thereby allowing the jar to be opened and closed both once and repeatedly.

The threaded lid may have an internal plastic gasket that will prevent the leakage of gas or liquid when closing the can again.

An air valve integrated in the opening mechanism will initiate the release of internal pressure from the top of the can during the initial opening phase before the liquid contained in the can is poured (drunk or poured into another vessel). This will reduce the risk of sudden spillage of liquid when opening the can.

The present invention contemplates the use of various types of “spouts” for drinking or emptying a can. One of them is a hard “nose” (neck), protruding outward from the base of the can (paragraph 6 of the claims). Another option is a "telescopic" design of the neck (paragraph 23 of the claims). When the can is closed, this spout is inside the opening mechanism and appears when opening the can, or at least if the can is open.

In general, the can closable can also have an attachable sealing container that is attached along the can axis to the can open-close mechanism (claim 24). It is located in the lower end of the can, on which the can stands on the surface. This container can serve as a holder for other consumer items, such as chips, nuts, baking, etc., as well as various promotional gifts, coupons, bonus cards, etc. The container can also be used as a glass for those who do not like to drink directly from the can.

Repeated tight closure leads to the preservation of freshness and other qualities of the contents of the can due to the fact that, for example, the maximum concentration of carbon dioxide in the liquid is maintained even after repeated opening and closing of the can. The ability to close an already opened jar at any time allows you to comply with hygiene requirements, to prevent the ingress of insects, etc. inside the can. At the same time, it remains possible to stack one can on another (paragraphs 12, 25 and 26 of the claims). The jar can be installed on the lid of another jar under the “bank in question” (RB). At the same time, it remains possible to fill the Republic of Belarus as a can, and not as a bottle. The can is filled through a large hole in its upper part, without a lid, while maintaining a stable position while being on the lid of another can. This cover covers the neck and a large stable surface along the shoulder along the radius, at least partially or intermittently (paragraphs 11, 12 of the claims). On the other hand, this shoulder allows you to dock RB along the outer circumference or around the circumference of the seam with the case of a closed can located under the RB in a pile (paragraph 33 of the claims). The bead has the same geometry as the seam of the same can, which allows you to stack cans of the same type in stacks one on top of the other.

The device for multiple closure of the can also contains the aforementioned collar in its construction (see paragraphs 5, 6 or 25). The shape of the shoulder and its dimensions are selected depending on the size and shape of the lid of the can.

Detailed Description of Various Embodiments of the Present Invention

The can for drinks 1 in all groups of drawings, from 1 to 4 (from “a” to “c”), is a sample obtained from a metal sheet using the DWI process. Its base has a convex profile 1.1, which is gradually rounded from the central axis of the can 100 to the outer circumference. The base profile protrudes outward relative to the inner surface 1i. The cross-sectional profile of a domed outwardly curved base of the can may be made in the form of one, two or three beams. The convexity depth can range from 2 to 33 (the ratio of the diameter to the convex depth), the preferred value lies in the region 7. The geometry of this profile can vary within wide limits. Throughout the bulge there are no steps and sharp transitions. The exact shape of this profile depends on the specific functionality and aesthetic perception.

At the base 1.1 of the can there is a round hole 1e located in the center, the axis of which coincides with the central axis of the can. The diameter of the hole ranges from 20 to 40 mm, the most preferred option is 26 mm (plus / minus 10%). This hole 1e remains open in order to attach the “neck” 3, allowing pouring liquid from a can or drinking. It is part of the device for repeatedly opening / closing the cans and is connected to other parts, performing at least the role of a component of the can lid 4.

The beverage can 1 may be made of a sheet of aluminum, plastic or cardboard, or a combination of the above materials. The preferred option is a sheet of metal. In the process of processing a metal sheet (DWI method), a cylindrical container is obtained having thinner walls 1b and a thicker bottom 1d. In the process of forming the neck of the can 1c, the upper part of the side wall 1b is formed radially towards the inside of the can, thereby creating a smaller hole for access to the inner cavity of the can 1i, which is closed by the lid 2, as shown in figa.

Fig. 1c shows in detail a can 1, a lid 2 and a closing device 4, 3 attached to the bottom of the can 1d. Fig. 1b is an enlarged view of a part of Fig. 1a, which shows the installation of the main element 3 at the bottom of the can, and the mechanism of the lid 4, which are shown assembled in the closed state of the can. Two threads of thread - one (4.1) on the neck 4a of the lid 4, and the other on the outer cylindrical surface of the element 3 - interact with each other to perform operations of opening and / or closing the banks.

The lid of the can 2 is made of steel or aluminum. It represents the top of a closed can. Although outwardly it looks like a common type of “easy-to-open lid”, it does not have an opening mechanism, i.e. there is no “broken” contour line or tongue on it. Its purpose is limited to closing and sealing the can after filling it. The can lid is an almost completely flat and even surface 2.1, which is connected to the inner rim by countersink (groove) 2.2, so that subsequently (when the lid is put on the open neck of the can 1c), compress the corresponding part of the side surface of the can body 1b, thereby forming , an annular flange 2.3, as shown in figa (left part of the drawing). The annular flange 2.3 is folded down over the entire outer circumference. The inner surface of the annular flange and the neck of the can are laid between themselves by a special connection, not shown in the drawing, which prevents the leakage of liquid or gas from the cavity of the can after the formation of a sealing seam 2.4, which is formed as a result of rolling the annular flange of the lid and the flange of the can body 2.5 after filling the can, as shown on the right side of figa.

Due to the fact that there is no mechanism for easy opening of the can, the lid of the can becomes more even, flat, geometrically undisturbed by anything. And thus, an almost ideal space appears for placing stickers, labels, printing advertising and other texts, graphic images. This cover is not intended to be opened or closed. It may have a slightly convex shape.

The neck 3 has a cylindrical shape and is a one-component part. This hollow inside part 3a, resembling a piece of tube in shape, is made of a highly molecular thermoplastic material. The outer surface of the neck has a thread 3.1, having from 1.5 to 2.5 turns at one end. The thread has a minimum of 3 and a maximum of 5 (most preferred value of 4) longitudinal cuts located parallel to the central axis 100 of the neck 3. At the base of each of these cuts there is one more small additional groove that is laid along the entire length of these thread spaces and by a small amount exceed this length at each end.

The end portion, opposite the threaded tube of the neck 3, has two flanges 3.3, which protrude outward around the entire circumference. Both flanges are separated by a gap having a dimension "d", which corresponds to the thickness of the sheet from which the bottom of the can 1.1 is made. After assembly, the neck 3 will be inserted into the opening 1e of the base of the can, the flanges are thermally sealed on each side with a special hot glue covering the surface of the edges of the opening 1e in the base of the can.

The neck flange, mounted and secured to the base of the can 1.1, is connected by means of jumpers 3.4 in an amount of 5 to 15 (most preferred amount 12) with a sealing ring 3.5, which has a U-shape in cross section. The drive mechanism 4.2 for interacting with the ring 3.5 is part of the design and will be further described in detail in the corresponding section.

An alternative embodiment of the neck 3 is shown in the drawings of groups 3 and 4, in which it has the designation 3 '. In this embodiment, the neck consists of two parts. The two-component neck 3 'has the shape of a hollow tube and is made of a high molecular weight thermoplastic material. The outer surface of the neck around the entire circumference has a thread 3.1 ', and on the inside there is a sliding annular surface 3.2'. It also has from 4 to 8 (the most preferred number 6) holes 3.3 ', which are located at the same distance from each other around the entire circumference, close to two annular flanges 3.4', which are used to fasten the outer part of the neck 3c to the base of the can 1.1 . The sliding portion 3.2 'is located in the end of the neck 3c, opposite the mounting flanges 3.4'. Closer to that end of the neck, on which the flanges are located, 2 to 3 turns of thread are wound. The thread has several, most preferred option 3, minimum 4, maximum 5, longitudinal cuts 3.5 ', which are parallel to the Central axis of the neck 100.

At the base of each of these cutouts there is one more small additional groove, which is laid along the entire length of these thread gaps and slightly exceeds this length at each end.

The end opposite the threaded portion of the neck 3 'has two flanges 3.4' that protrude outward around the entire circumference. The flange from the outer side of the neck enters an annular protrusion, which in cross section has an almost circular shape of its outer surface, and they coincide along the axis. Both flanges have a gap between them with a size corresponding to the thickness of the material from which the bottom of the can is made, as already described above. During assembly, the neck 3 'is inserted into the opening 1e of the base of the can 1.1, the flanges are thermally sealed on each side with a special hot glue covering the edges of the holes 1e in the base of the can. Due to this, the edges of the open hole 1c will not corrode.

The neck flange, located on the outside of the base of the can, is connected to a sealing ring confirming the authenticity of the 3.8 'product, which in the cross section is U-shaped by means of thin jumpers in an amount of 5 to 15, the most preferred number of jumpers 12. Drive mechanism 4.9 '' to detach the 3.8 'ring is part of the entire can opener and will be described in more detail in the following sections.

The inner part 3b of the neck 3 'has a thread 3.9 both from the outside and from the inside. Both threads are located in the same part of this inner part. The external thread 3.9 'on the outside of the part corresponds to the internal thread 3.1', which is wound on the inside of the outer part of the neck. The internal thread 3.9 'on the inner side corresponds to the thread that is wound on the outside of the closure cover 4 and its sleeve 4a, which will be described in more detail in the following sections.

The inner part of the neck 3b ends with a conical section 3.10 ', on which the thread ends. This portion corresponds to a slightly narrower conical mating portion at the site of the closing lid to achieve a snug fit between both parts while opening the entire system. These cone sections are separated from each other only at the end of the axial movement of the inner part of the neck 3b relative to the outer part 3c. This happens when the inner part is fully extended during the first phase of the system opening process. These cone sections again fully engage only at the end of the reverse movement, i.e. in the process of closing the system.

The other end of the inner part, located on the far side from the threaded portion, has an outwardly extending flange 3.11 ', which moves along the sliding inner surface of the outer part of the neck during the opening and closing processes of the system. The flange stops its axial movement in two extreme positions relative to this internal sliding surface.

The end of the inner part, on which the flanges are located, has several cuts 3.12 ', from 4 to 8, the most preferred number of cuts 6. These cuts allow mechanical assembly of the inner and outer parts, as well as place the annular flange 3.11' inside the sliding surface 3.2 '.

The screw cover 4 in FIG. 1a to 1c is a cylindrical structure made of a high molecular weight thermoplastic. Its outer diameter mainly corresponds to the outer diameter of the side surface of the can body 1b. The lid has a centrally located sleeve 4a, which is attached to the pad 4.4 and which has an internal thread 4.1 on the inner surface of the tube (type "mother"). Both of these parameters — both the thread and the diameter of the inner “closing” coupling — correspond to the counterpart of the neck 3 (of the “male” type) and together make up the part “coupling 4a, 4.1”.

The central inner part, which is in the form of a tube, also carries a U-shaped counterpart 4.2 for installing a sealing ring confirming the authenticity of the product. The U-shaped part on the cover 4 is divided into several segments 4.3, from 4 to 15, the most preferred number of segments 12. They allow the “elastic” engagement of the U-shaped sealing ring 3.5, attached with jumpers 3.4 to the outer part of the flange 3.3 of the neck 3 only during the initial assembly of the closing assembly 4, rotating it along the thread 3.1 and thereby creating an axial bias stress of the circular segments 4.3 before their latch is locked with the corresponding latch of the U-shaped sealing rings 3.5. On fig.1b this system is depicted in a closed state.

The U-shaped sealing ring 3.5 will break during the first opening of the can, the jumpers 3.4 will break and remain inside the screw cap 4 - inside the part 4.3. The fact that the sealing ring is broken can be felt by a sharp change in rotation resistance or by the characteristic clicking sound, which is present only when the can is opened for the first time.

The flat platform 4.4 on the inside of the screw cap 4 is provided with a sealing gasket 4.5, which prevents the leakage of gas or liquid from a closed can.

The platform 4.4 of the screw cover basically has a flat surface, on the outer side of which there is a shoulder 4.6, next to the outer circumference, as well as a small rim 4.7, which is a transition element from the flat surface of the platform to the cylindrical side surface 4.8.

The diameter of the flange and the inclination of the rim portion is chosen so that the closing cover 4 corresponds to the geometry of the top cover of the can (for stability and joining of the cans), it is desirable that the diameter coincides with the outer diameter of the seam 2.4. This will ensure a stable position of the cans in the stack when they are located one above the other. The lower flange of the cover 4 is selected in accordance with the geometry of the opposite end, i.e. top cover. This is called “docking with cover geometry.”

The outer side of the cylindrical side surface 4.8 is provided with a corrugated portion 4.9 to facilitate gripping and holding the can during the opening or closing operation of the can by the consumer. The corrugated surface 4c outside the cover is one of the versions of the "capture area" on the cover 4.

The closing screw cap 4 'in another design (Figs. 2a to 2c) is identical to the above, with the following exceptions:

the outer side walls 4.1 'of the screw cap 4' have a stepped design, i.e. the diameter of the lid varies along the central axis. This stepped design has a diameter identical to the diameter of the can on the one hand, and on the other hand, the diameter becomes smaller (in that part where the side surface goes into an inclined rim 4.7). The outer surface of the side walls is equipped with special latches 4.2, from 3 to 7, but the most appropriate 5 latches, which are located next to the transition section from small to large diameters. These latches provide mechanical engagement with the optional additional cup 5, described below, which has a few threaded sections Y in a minimal version. The section of the inclined rim 4.7 in this embodiment should also correspond to the seam 2.4 on the top cover of another can.

The next embodiment of a cylindrical screw cap 4 "made of a high molecular weight thermoplastic material is shown in Figs. 3a to 3c. The outer side surface of the walls 4.1" according to this embodiment also has a cylindrical shape with respect to the central axis 100 and has the same diameter, as the can itself. Through a small inclined section of the rim 4.2 '', it passes into a flange 4.3 ''. This flange 4.3 '' is also made in such a way as to ensure docking with a seam weld 2.4 of the top cover of another can.

The section of the construction adjacent to the shoulder 4.3 '' is equipped with several latches 4.4 '', from 3 to 7, the most appropriate number of latches 5. These latches provide mechanical engagement with the optional additional cylindrical cup 5, which will be described later. The 4 '' screw cap also has an inner sleeve located centrally along the central axis 100, with a 4.5 '' thread wound around its outer surface. Both of these parameters — both the diameter and the thread of the inner sleeve — correspond to the counterparts of the telescopic neck 3 ′. The inner surface of the screw cap 4 ″ directed along the central axis has an annular recess 4.6 ″, preferably conical in cross section, geometrically coinciding with the end portion 3.10 ″ of the telescopic portion 3b of the neck 3 ′. Conical mating parts of the “father” and “mother” type engage the telescopic part 3b and the screw cap 4 '' with each other when the screw cap is twisted clockwise to its extreme position. This engagement allows the telescopic portion to be pulled out of the neck 3 'when the can is opened by rotating the cap 4' 'counterclockwise.

The inner surface of the pad of the screw cap 4 ″ also has an annular groove 4.7 ″ filled with a seal 4.8 ″, which in its geometric shape corresponds to the outer bulge 3.6 ″ of the outer flange 3.4 ″ of the neck 3 ″. The seal and this bulge provide a tight connection and prevent leakage of gas or liquid from the tank when it is in a closed state.

The lockable screw cap 4 ″ section also has U-shaped mating parts 4.9 ″ for a 3.8 ″ sealing ring, the interaction of which has been described above.

The U-shaped portion 4.9 ″ on the 4 ″ screw cap is divided into several segments, from 4 to 15, preferably 12 sectors. This separation makes it possible to obtain elastic engagement of the elements of the counterpart 4.9 "and the sealing ring 3.8 'itself, which is attached with jumpers to the outer flange of the fixed part of the cover 3c only at the stage of initial assembly of the assembly. The sealing ring will be broken (the jumpers will break) during the first opening of the closed cover, and it will remain inside the U-shaped mating part, i.e. inside the lid. The fact that the sealing ring is broken can be felt by a sharp change in rotation resistance or by the characteristic clicking sound, which is present only when the can is opened for the first time.

The closing screw cap 4 "in another design (Figs. 4a to 4c) is largely identical to the above, with the following exceptions:

The 4 '' screw cap has a smaller diameter pad 4.1 ''. This pad with a reduced diameter performs the same functions as a conventional 4 '' screw cap, and is a supporting element for 4.4 '' parts that are located on a circle with a diameter equal to the diameter of the can, while saving material due to such an integral design. It can consist of 3-7 (preferably 5) beams, some or all of which have devices (latches) for mechanical connection with an optional cup 5, on which there are corresponding reciprocal latches Y and the description of which will be given below.

Legs 4.2 '' in size correspond to the diameter of the collar 4.6 (as in the first embodiment), i.e. made in such a way as to dock with a seam seam 2.4 of the top cover, providing the possibility of installing cans in a stack, one above the other. The same applies to the other side of the bank, as it is assumed that they are all of the same type.

An additional optional vessel 5 (groups of drawings 3 and 4) is made of high molecular weight thermoplastic material. It is desirable that it has a cylindrical shape, similar to a glass, with an open upper part and a closed bottom from the bottom (5b). The dimensions and geometry of the upper part must be such that they coincide with the outer diameter of the container body in its lower part (1b). The bottom 5b of the vessel with the outer flange 5b 'corresponds to the geometry of the screw caps 4, 4', 4 '' and 4 '' ', which allows different variants of glasses and containers to be joined together.

The upper inner part of the vessel has from three to seven (preferably 5) threaded sections 5.2, which are separated by gaps 5.1, forming the engagement zones Y at a distance from the upper edge of the glass 5. This distance approximately corresponds to the height of the outer “skirt” 4.1 ”, 4.2 '' or 4.1 ', including the height of the rim or the height of the legs 4.2 ".

The threaded sections 5.2 in their location and size correspond to latches 4.4 '' ', 4.2' or 4.3 "of screw caps of any modifications. The closure of the cover and the cup are connected by rotating the cup around the central axis 100 clockwise. The cup is disconnected by rotating it counterclockwise arrows around the central axis.

The 4 '' and 4 '' 'cover caps have a fairly flat and even construction on their underside. Therefore, they are most suitable for using an additional cup 5 with them, since the overall height of the entire system is reduced, while still being able to dock them both with the cup and without it with the top cover 2.4 of another can.

The ability to dock various components.

Jar 1 and lid 2 in their dimensions and geometry are suitable for all types of neck and screw caps as well as for all designs of additional glasses.

The one-component neck 3 can be connected with screw caps 4 and 4 ', with or without an additional glass 5.

The two-piece neck 3 'can be connected to the 4 "and 4" "screw caps.

An additional cup 5 can be attached to the screw caps 4 ', 4 "and 4".
