Description

Reclosable beverage cans, caps and cups {RECLOSABLE BEVERAGE CAN, CAP AND CUP}

The present invention relates to reclosable cans and cans filled with contents suitable for reuse and reclosing after only a portion of the contents of the can (with the body and lids) have been consumed.

Metallic beverage cans (with a two-part system, with a can body and can lid in one base) are one of the most widely known as disposable containers. Consumers like this container because of its ease of handling, excellent protection of its contents and many other useful features.

Beverage cans are widespread for drinking at home, indoors and outdoors. Drinking outside the home, for example during travel, during sports and other events, constitutes a significant proportion. In the latter, the contents of the cans are often stopped without being consumed at once, so it can take an hour or more for the cans to be completely emptied. Despite the fact that beverage cans were originally designed for disposable use only, the cans lack reclosing properties in this respect.

The reclosing function is thought to be a useful property not only to maintain product freshness after partial product consumption, but also to protect the product from contamination and insect intrusion of the product from the time of opening to the final emptying of the can. The latter also suggests health and hygiene risks that cannot be overlooked during outdoor drinking.

Referring to WO-A 97/36739 (Schmalbach-Lubeca, Lutz Strube) or WO-A 01/66431 (Goetz, Ackermann, Folland), prior art of opening the lead side of a can and sealing it with a cap in the same axial direction Known. Referring to WO-A 03/066455 (Schmalbach-Lubeca, Ball Europe, Bert Bast et al.), It has already been proposed that the bottom (base) of the can is penetrated for sealing when using an inwardly domed shape. . Cans with reclosing leads in the spout and raised floors are disclosed in DE-A 198 02 953 (Rasselstein Hoesch), but substantially at the bottom (top) that bulges outward to expand in axial height under the pressure of the cans. It has a columnar step, and there is no actual support / support facility for filling cans. The beverage cans use a bottle filling method that is filled through a spout.

It is an object of the present invention to eliminate the disadvantages of a two-part can system that meets the needs of the consumer and is not reclosable by providing the convenience of resealing.

The present invention is intended to improve the suitability for outdoor use and long-term drinking by enabling consumers to effectively reseal the "take out opening" of the can every time they carry it out after having some drinking and going out. .

The present invention provides components which cooperate with each other according to claims 1 to 4 for beverage cans or claims 28 to 32 for stackable bodies of cans. The components,

1. Can body for containing liquids such as beverages

2. As an option, can lead

3. Spouts attached to the bottom for pouring or drinking

4. Cap for reclosable screwable

5. Optional containment vessel

to be.

The present invention provides the feature of a reclosable finish adjacent the base of the can or can body, as opposed to a reclosable can lid. The unopened end of the can accommodates a standard design. That is, it may or may not have a necking portion on the wall and a body hook flange formed on the top of the can body.

A concave shaped dome is typically a (inwardly) shaped base of the can, which is replaced by a convex shape that is curved outwardly (axially). The curved shape that forms the dome outward is a smooth shape with no intermediate step near the wall or the snout. The curvature of the curved bottom may vary from a smaller value to a larger value, although the absolute value may vary from radially outer to the inner side adjacent to the hole, but does not change depending on the direction. This "three radius geometry" describes the curved floor.

Circular holes centered in the molded base provide openings for permanent installation of the carrier for the reclosing finish. A reclosing finish with a flat rim that protrudes outwards after being attached, allows its packaging to allow the packaging material to be placed on any flat support, such as conveyors, mechanical seals, shelves for display and the top of other cans. It allows you to maintain a static pause.

The present invention provides that the beverage can is operated by a finisher device located in the can base. The finish may be provided preassembled by the can producer before the can body is fed to the filling point. Fillers handle cans in a conventional manner and do not require modifications to the filling and seam processing processes. After the can body is filled through a second fully open axial end, the can body is covered with can lids which are seam to the can body to seal and seal the container containing the beverage therein. Can leads ("ends") used for sealing at the point where the filling machine is located have no opening tabs or other instruments, ie those commonly used for "easy open ends", and are non-openable ends (and thus non-closable leads). It's just

The reclosable (openable, sealable) finish device includes a spout for pouring or drinking and a reclosable cap screwable. The cylindrical spout is installed in a hole provided near the center of the convex shape of the can base.

Having a thread suitable for the thread of the spout, the twistable cap allows for the opening and closing of the can, ie initial sealing and (additional) reclosing.

The screw cap may have a built-in plastic gasket that assists the packaging material in reclosing the gas and liquid while keeping it in contact with the spout.

The built-in outlet characteristics inside the finish begin to depressurize the internal pressure from the liquid-free space portion at the top of the can before the liquid contents are discharged from the can by drinking or pouring in the initial stage of opening. The accidental risk of liquid splashing during the can opening is at least reduced.

Reclosable finishes may have a tamper evidence feature near the bottom edge to allow consumers to recognize whether a beverage can is new or pre-opened.

Spouts for different types of pouring or drinking are presented. One is rigid and protrudes outward from the can base (claim 8). The other is a stretchable shape (claim 26) wherein the spout projects inward from the can base in a closed state and outward in an open or at least ready to open.

The entire reclosable can can have a detachable receiving bezel axially attached to the reclosable finish (claim 27). It is located on the bottom located at the tip of the can.

The storage bezel can accommodate chips, nuts, crackers or other snacks, or items for the consumer, such as advertising gifts, coupons or messages. The storage bezel can also be used as a drinking cup if you are reluctant to drink directly from the can.

Reclosing results in prolonging the freshness of the can contents by, for example, keeping the remaining carbonic acid at its maximum throughout the drinking period if the can is resealed. Reclosing also prevents the entry of contaminants, especially bugs, into the beverage contents and improves the hygiene and safety of the packaging for the benefit of the consumer.

Beverage cans are stackable (claims 14, 15, 28). The cup or cap fits over the lead end of the other can under the "can under consideration (CUC)". This "CUC" enables "can type filling" instead of "bottle type filling". Filling of the can is through a wide open end with a firm and stable stand on the cap or cup without covering the lid. The cap covers the snout and secures a wide stand face in the rim which is at least partially or intermittently in the radial direction (claims 13, 14). On the other hand, this rim makes it possible to stack so that there is a "CUC" radially outward or radially inward with respect to the shim of the canned and occluded can body arranged under the "CUC" in the stacked pile ( 29. In this way the rim is adapted to the core of the same can in geometric shape, even if it is in a nested arrangement with another can of the same shape for lamination.

With reference to claim 8 or 7 or 15, the rim belongs to a reclosing cap device (reclosing finish). The shape and size of the rim is selected according to the size of the lid geometry.

The present invention includes several embodiments to improve the spirit of the present invention and has four drawing groups.

1 is a first embodiment shown in three sets of figures (FIGS. 1A, 1B and 1C).

FIG. 2 is a second embodiment shown in three sets of figures (FIGS. 2A, 2B and 2C).

3 is a third embodiment shown in three sets of figures (FIGS. 3A, 3B and 3C).

FIG. 4 is a fourth embodiment shown in three sets of figures (FIGS. 4A, 4B and 4C).

Each figure has a, b, and c sets (e.g., FIGS. 1A, 1B, and 1C), each set having a side view showing a seam (right) flange and a seam (left) flange (a) ), An enlarged view (b) of a portion adjacent to the base, and an exploded view (c) showing the components.

The beverage can 1 of FIGS. 1 to 4 (including a to c) is an example produced by a drawing and wall ironing (DWI) process from a cup of metal sheet. The can has a convex base contour 1.1 extending laterally from the can's central axis 100. The base contour projects outward from the interior 1i of the can. The cross-sectional contour of the can base, which is convex to form a dome outward, may have one, two or three radii. The depth of the convex surface may have a ratio of diameter to depth in the range of 2 to 33, preferably about 7. The geometry for the base contour can vary widely. The base has no step along the dome shape.

The exact contour shape is derived by functional or aesthetic aspect.

The can base 1.1 has a circular hole 1e at the center thereof so as to coincide with the center axis of the can. The diameter of the hole is between 20 mm and 40 mm, preferably about 26 mm (± 10%). The rim of the opening formed by the hole 1e is for receiving the spout device 3 for pouring or drinking. The spout device is part of a reclosable finish with at least additional components such as a reclosable finish, such as the cap device 4.

The beverage can 1 is made from a sheet of steel, aluminum, plastic, cardboard or a combination thereof. One preferred example is a thin metal plate.

The DWI process uses a thin sheet of metal to provide a cylindrical container with a thin wall 1b and a thicker bottom 1d. In the necking process, as shown in FIG. 1A, the upper end 1c of the wall 1b is molded radially inward to reduce the opening diameter of the can interior 1i to access the lid 2.

FIG. 1C shows an exploded view of the can 1, the lid 2 and the devices 4, 3 for sealing the bottom end 1d of the can. FIG. 1B is a partially enlarged view of FIG. 1A showing permanent mounting of the carrier 3 to the bottom of the can and attachment of the cap device 4 in a closed state. The two threads, ie the threaded portion 4.1 formed in the socket 4a of the cap 4 and the threaded portion formed on the radially outer surface of the tubular carrier 3, interact for opening and / or sealing.

Can leads 2 are made of steel or aluminum. The lid is the upper end of a sealed can. The lid is similar to the tip of a widely used easy open can, but does not have a mechanism to facilitate opening. That is, there is no pre-inscribed gold or handle. The function of the lid is limited to sealing and sealing the can body after filling. The can lid is countersunk (grooves) via an internal chime when placed on the necked walls 1b, 1c that are open in the yet unsealed state, as shown in FIG. 1A (left portion). And a substantially flat end panel 2.1, which is connected to the chuck wall by means of 2.2 and terminates at the annular end flange portion 2.3. The end flange portion 2.3 has an outer rim bent downward. The inner surface and the bent portion of the end flange portion wrap the (double) seam 2.4 by wrapping the end flange and the can body flange (body hook) 2.5 as shown in the right part of FIG. 1A. After formation, it is filled with a sealing compound, not shown, which establishes the airtightness of liquids and gases.

Since there is no mechanism to facilitate opening, the panel 2.1 of the can lid remains flat and geometrically free of distortion. The panel thus provides an ideal basis for expanding the billboard of the container by printing or labeling additional messages and / or images. Panels are neither open nor sealed. The panel may have a slightly dome-like shape.

The integral cylindrical spout 3 is a hollow tube shape 3a made of a thermoplastic polymer material. The outer portion of the snout is threaded at one end with a rotational speed between 1½ and 2½. The thread has at least three, at most five, preferably four longitudinal interruptions 3.2 along an axis parallel to the central axis 100 of the spout 3. The base of each thread halter has an additional small grove projecting over the entire length of the thread halter and slightly exceeds the total length of the thread halter at both ends.

The opposite end of the threaded tube of the spout 3 comprises two flanges 3.3 formed radially outward. The two flanges are spaced apart by a distance “d” corresponding to the plate thickness of the can base 1.1. After assembling the spout 3 into the can 1e of the can base, the flanges are coated on both sides with a heat-sealable material around the can 1e of the can base which accommodates the spout 3. It is sealed by heat.

The flange of the spout permanently installed on the outer side of the can base (1.1) has a tamper evidence ring (3.5) with a U-shaped cross section through 5 to 15, preferably 12 straps (3.4). ) The implement (4.2) for handling the proof ring is part of the design of the closing cap and will be described later with a description of the relevant parts.

Another embodiment of the spout 3 is shown as spout 3 'in FIGS. 3 and 4. Two-part spout 3 is a tube shape made of a thermoplastic polymer material. A thread (3.1 ') is formed in the radially outer portion of the spout and a 360 ° sliding bed (3.2') is provided inside. The spout is adjacent to two radial flange portions 3.4 'for mounting the outer portion 3c of the spout to the can base 1.1, with four to eight, preferably six window shaped openings 3.3 It is preferable that ') is formed at equal intervals around it. The slide bed 3.2 'is located at the axial end of the outer part 3c of the spout opposite the mounting flange 3.4'. A screw thread of two to three turns is located at the flange end of the spout. The threads have several, preferably at least three to four or five longitudinal stops 3.5 'in the axial direction parallel to the central axis 100 of the snout.

The base of each threaded midsection has an additional small grove projecting over the entire length of the threaded midsection and slightly exceeds the full length of the threaded midsection at both ends.

The opposite end of the threaded tube of spout 3 'includes two flanges 3.4' formed radially outward. The flange outside the snout extends to an annular projection 3.6 'having a substantially circular cross section, facing axially on the outer side. As described above, the two flanges are spaced apart by a distance corresponding to the plate thickness of the can base. After assembling the spout 3 'of the other embodiment into the hole 1e of the can base, the flanges are coated with a heat-sealable material around the opening 1e of the can base containing the spout 3. The two surfaces are heat-sealed. By this attachment the ends of the holes 1c will be corrosion resistant.

The flange of the spout located on the outer side of the can base has a tamper evidence ring having a substantially 'u' shaped cross section through five to fifteen, preferably twelve thin straps (3.7 ') ( 3.8 '). An actuating mechanism (4.9 ") for separating the tear proof ring is described later.

The radially inner portion 3b of the spout 3 'is formed with additional threads 3.9' on the inner and outer surfaces in the radial direction, respectively. Both threads are located at the same end of the inner portion of the snout. The outer thread 3.9 'on the outer side coincides with the inner thread 3.1' on the inner side of the spout outer portion. The inner thread 3.9 'of the inner side coincides with the thread on the radially outer side of the closing cap 4 and the socket 4a. The closing cap 4 and the socket 4a will be described later.

The spout inner portion 3b ends with a tapered portion 3.10 'at the threaded end. The inner portion of the spout corresponds tightly to the slightly narrow tapered receiving portion of the panel of the closure cap, allowing the two portions to lock together while opening the closure system. These tapers are separated only at the final stage of axial movement with respect to the spout outer part 3c of the spout inner part 3b. This is when the inner part of the spout is fully stretched (extended) in the first stage of the finish opening process. These tapers relock only at the final stage of relative movement in the reclosing process.

The end of the inner side of the spout located away from the threads includes an outwardly facing radial flange 3.11 '. This radial flange runs in a sliding bed outside the spout during the opening and closing of the reclosable finish. This flange terminates the movement of the inner portion of the snout at the dead point of the slide bed.

The flanged end of the inner portion of the spout has four to eight pieces so as to mechanically assemble the inner portion of the spout into the outer portion of the spout and to assemble the radial flange (3.11 ') to engage the bed (3.2'), It is preferably designed to have six gaps (3.12 ').

The reclosing screw cap 4 of FIGS. 1A-1C is cylindrical in shape made of a thermoplastic polymer material. The outer diameter of the screw cap is substantially equivalent to the outer diameter of the can wall 1b. The cap has an inner tube portion 4a centered on the panel 4.4 and has a thread 4.1 (female threaded shape) on the inner side of the tube. The thread and diameter of the inner "reclosing part" coincide with each corresponding counterpart of the spout 3 (male thread shape). This is called socket 4a (4.1).

The central inner tube portion also has a 'u' shaped corresponding piece (4.2) as a proof feature of the reclosable finishing system. The 'u' shaped portion of the cap 4 is divided into four to fifteen, preferably twelve circumferential dividers 4.3. It is thereby possible to engage "spring driven" with the 'u' tear proof ring 3.5 attached to the outer part of the flange 3.3 of the spout 3 by the strap 3.4. In other words, during the initial assembly of the cap 4, the cap is tightened against the thread 3.1 and the axial displacement prior to engaging the hook portion of the divider with the corresponding hook of the 'u'-shaped ring 3.5. Elastic deformation in the radial direction. 1B shows the locked state.

The proof ring, which is in principle 'u' shaped (3.5), is torn by breaking the thin strap (3.4) during the initial rotational opening of the reclosable finishing system and the 'u' shaped inside the screw cap (4). It remains captured by the part (4.3). Opening evidence is perceived by a sudden change in resistance torque and by acoustic means only at the first opening of the finish.

The panel 4.4 of the inner part of the screw cap 4 is provided with a gasket type seal plate 4.5 to ensure gas and liquid tightness of the sealed cap.

The entire panel 4.4 of the screw cap is substantially flat in shape, with an outer chime by means of a rim portion 4.6 adjacent the outer circumference and a transition section from the flat panel to the cylindrical wall 4.8 via the rim. (chime) has a portion (4.7).

The diameter of the rim and the inclination of the chime are selected depending on whether the sealing cap 4 can be fitted into the can lid geometry (for stackability of the can), but radially outward of the shim 2.4. Is preferably. This makes it possible to safely stack filled cans on top of each can in turn. The bottom rim of the cap 4 is selected based on the opposite end (i.e. lid) which is seamed and can be nested in turn. It is said to be "superimposed on the geometry of the lead".

Handle grooves 4.9 are formed on the outer side of the cylindrical wall 4.8 of the cap to facilitate opening and closing by the consumer. As an embodiment of the "grabbing surface" for the cap 4, the rib 4 formed face 4 faces the radially outer side.

The reclosable screw cap 4 ′ of another embodiment shown in FIGS. 2A-2C is identical to the reclosable cap 4 described above except for the following.

The wall 4.1 'on the outer circumference of the screw cap 4' has a stepped shape and changes in diameter along the axial direction. The stepped shape has a diameter equal to the diameter of the can at one end and a smaller diameter at the other end before the chime part 4.7. On the outer side wall, at least three, at most seven, preferably five locking keys 4. 2 ′ are formed at points adjacent to the portion 4.3 ′ which transitions from the smaller diameter to the larger diameter. These locking keys are for mechanically locking and filling the optional receiving bezel 5. The storage bezel 5 has at least a portion of the thread Y, which will be described later.

The chime part 4.7 of the present embodiment may also be nested in the shim 2.4 of another can.

Another reclosable screw cap 4 "is in the shape of a circle made of thermoplastic polymer material as shown in Figures 3A to 3C. The wall 4.1. 1 of the outer circumference of the third screw cap 4" is axial It is tubular in the direction 100 and has the same diameter as the beverage can. The outer peripheral wall is connected to the rim portion 4.3 "of the screw cap via the chime part 4.2". The rim portion 4.3 "is also It is adapted to be nested or stacked with a shim corresponding to the shim (2.4) at the other end.

The chime portion 4.3 "is provided with at least three, at most seven and preferably five locking keys 4.4". These locking keys are for mechanically locking and filling the cylindrical receiving bezel 5 which will be described later as an option. The screw cap 4 "also has a central inner tube socket portion with a threaded 4.5" on the outer surface. The thread and diameter of the inner "reclosable part" coincide with each corresponding part of the flexible spout 3 '. The inner surface of the panel of the screw cap 4 "facing in the axial direction is preferably formed with an annular groove 4.6" having a tapered cross section, and the annular groove is geometrically expanded to the expansion portion of the spout 3 '( Coincide with the tapered end portion (3.10 ") of 3b). The male and female taper engages the spout telescopic portion (3b) and the screw cap (4") when the screw cap is locked to a clockwise dead point. This frictional locking causes the expansion and contraction of the spout 3 'to move out of the container when opened by the counterclockwise rotation of the screw cap 4 ".

The inner side of the panel of the screw cap 4 "is also provided with a groove 4.7", which is geometrically shaped with the outer projection 3.6 'formed in the outer flange of the flange 3.4' of the spout 3 '. Inlet seals (4.8 ") are formed to match the seals. The seals and protrusions ensure gas and liquid tightness of the container when the reclosable finish is in the closed condition.

The panel of the reclosable screw cap (4 ") is also a 'u' shaped corresponding piece (4.9" in principle, which acts as previously described as the proof proof properties (4.9 ") (3.8 ') of the reclosable finish. )

The 'u' shaped part 4.9 "of the screw cap 4" is divided into several pieces, preferably 4 to 15 or about 12 parts in the axial direction. This is in principle driven by a 'u' shaped opening proof ring (3.8 ') and a spring attached to the outer flange of the fixing part 3c of the spout 3' by the strap 3.7 'during the initial assembly of the screw cap. Possible (elastic) engagement. The proof ring is torn due to the breakage of the thin straps during the initial opening of the reclosable finish, which remains captured by the 'u' shaped part inside the screw cap. Opening evidence is perceived by a sudden change in resistance torque and / or by acoustic means only upon initial opening of the finish.

In another embodiment the reclosable cap 4 '' 'of FIGS. 4A-4C is substantially the same as the reclosable cap described in Example 4 ", except as follows.

The screw cap 4 '' 'has a panel 4.1' '' of reduced diameter. The diameter reducing panel (4.1 '' ') has the same characteristics as the screw cap (4 "), while the bridging parts (4.4' '') with respect to the can body diameter are partially open and used. The screw caps have three to seven, preferably five braces (4.2 '' '), at least some of which are container stacking and have locking keys (4.3' ''). And mechanically lock and fill the optional receiving bezel 5 to be described below by means of a corresponding catch Y.

The brace 4.2 '' 'functionally corresponds to the rim 4.6 of the first embodiment and has a geometric shape suitable for the shim 2.4 so that it is radially inward or outward of the shim-treated end of the closed container located below it. By being nested in, it allows for "lamination properties". This also applies to the other end of the same container, assuming all containers are the same.

The additional receiving bezel 5 of FIGS. 3 and 4 is made of thermoplastic polymeric material. The storage bezel is preferably cup-shaped with an open top and a closed bottom 5b. The upper geometric shape substantially coincides with the outer diameter of the container body at the bottom of the wall 1b. The bottom 5b of the receiving bezel has a geometric shape 5b 'which is similar to the contour of the screw caps 4, 4', 4 ", 4 '' ', to allow stacking of the container provided with the cup.

The upper inner side of the accommodating bezel has a threaded portion 5.2 having three to seven, preferably five mountains, and the threaded portion Y at a point spaced a predetermined distance from the upper edge of the accommodating bezel 5. A stop section (5.1) is provided. The predetermined distance substantially corresponds to the amount of axial expansion of the outer skirt 4.1 ", 4.2" or 4.1 ', including the length of each chime or brace 4.2' ''.

The middle section 5.2 coincides with a locking key 4.4 '' 'or 4.2' or 4.3 '' 'around the different screw caps. Engagement of the storage bezel and the container is achieved by rotating the storage bezel clockwise with respect to the container about the central axis 100. The detachment of the storage bezel is achieved by rotating the storage bezel counterclockwise with respect to the container about the central axis.

The caps 4 "and 4 '" are axially platter-shaped. They are provided with the separable receiving bezel 5 to reduce the overall axial length of the assembled packaging material and to accommodate the receiving bezel 5 It is desirable to be stackable with the shim (2.4) shape at the other end, with or without).

Easy assembly of components

Cans 1 and lids 2 fit snugly and screw caps as well as the shape of the receiving bezel.

The integrated spout 3 fits the caps 4 and 4 'with or without the receiving bezel 5.

The two part spout 3 'fits into the caps 4 "and 4' ''.

The receiving bezel 5 fits the caps 4 ', 4 "and 4' ''.

The present invention can eliminate the disadvantages of a two-part can system that meets the needs of the consumer and is not reclosable by providing the convenience of reclosing.

The present invention can improve the suitability for outdoor use and drinking for a long time by enabling the consumer to effectively reclose the "take out opening" of the can every time he carries it after having some drinking and going out. .
