Description

  The present invention relates to a can body and a filling can that can be re-occluded, and more particularly to a can body and a filling can that can be re-occluded after being used (with a body and a lid) and partially consuming the contents of the can. .

  Beverage cans (a two-piece body with two parts, a can body and a can lid as an integrated base), the world's most accepted single serving packaging container one of. Consumers use this packaging because of its ease of handling, quality, content protection, and many conveniences.

  Beverage cans are common for beverage consumption at home, indoors and outdoors. For example, it shows a high percentage of out-of-home consumption such as in travel, sports and entertainment. When used outdoors, the contents of the can are not consumed immediately, but are often consumed after a while, and it takes an hour or more before the can is empty. There is also. In such cases, beverage cans are originally designed for single use but lack re-occlusion.

  Resealability is useful not only to keep the product fresh after it has been partially consumed, but also to protect the product from contamination and insect invasion from the first opening of the can until the can is empty. It is believed that there is. The latter also means a non-negligible health and hygiene risk when consumed outdoors.

As a conventional technique, there is known a technique in which a can is opened from a lid side and a cap is put on the same shaft side to be closed (for example, Patent Document 1 and Patent Document 2). When the bottom part formed hemispherically toward the inside is employed, the bottom part (base part) of the can that has been inserted for closing has already been proposed (for example, Patent Document 3). A raised bottom can having a cap for re-occlusion on the mouth is shown (for example, Patent Document 4). However, under the internal pressure of the can, the can has an increased height in the axial direction, and has a substantially circumferential step at the bottom (upper side) that bulges outward. There is no standing / support facility to allow filling such as cans. For this reason, the beverage can is filled from the bottle-shaped mouth.

  It is an object of the present invention to eliminate the disadvantages of a two-piece can structure that cannot be re-occluded by providing the convenience of re-occlusion and to satisfy consumer demands.

  The present invention enables cans to be used outdoors as well as for extended periods of time by allowing the consumer to effectively reclose the opened can each time a consumer consumes a portion of the contents. It is improved to suit.

  The present invention proposes cooperating components as described in any of claims 1 to 4 for beverage cans or as described in any of claims 27 to 30 for stackable can bodies. Yes. The components are shown below.

1. 1. Can body that holds liquid such as beverage 2. Can lid, if necessary 3. Infusion or drinking area, cooperating with the bottom 4. Screw type re-closable cap Containment-vessel, added as needed

  The present invention is characterized in that, unlike a re-closable can lid, a re-closure closure portion is provided near the base of the can or the can body. The end of the can that cannot be opened has a normal design regardless of whether or not the wall has a reduced diameter, and is provided with a flange of the main body formed at the uppermost end of the can body.

  The conventional concave hemisphere as the (inward) shape of the base of the can is replaced by a convex design that bulges outward (in the axial direction). The shape that bulges to the outer hemisphere is soft (soft shape), and there is no step at the middle portion near the wall or the inlet. The curvature of the bulged bottom does not change even when the direction changes, while the absolute value changes from a small value to a large value from the outside in the radial direction toward the inside opening. The bottom bulged by this “three radius geometry” will be explained.

  The circular opening at the center of the base formed in this way is an opening for permanently attaching a carrier for the reocclusion occlusion. After being attached, the closing block has a uniform edge protruding outwards, and the packaging device is placed on the periphery, for example on a conveyor, on a transport pad, on a display shelf, It is possible to place any number of steps flat on other cans in a stationary state.

  The present invention allows beverage cans to be handled on a closure component located at the base of the can. The closure may be preassembled by the can manufacturer before the can body is supplied to the place where it is filled. The filler can handle the can as usual without any modifications to the filling and closing process. After the can body has been filled from the second axial end in its entirety, the second end is closed to the can body to seal and close the container filled with the beverage. Covered with a can lid. The can lid ("end"), which is closed where the filler is, is not provided with a tab or other mechanism for opening, so it is '' easy to use '' It is not an end ”that can be opened, but an end that cannot be opened (ie, a lid that cannot be closed).

  The reoccludeable (openable and occlusive) occlusion component consists of an injection or drinking mouth and a reocclusive screwable cap. The columnar mouth is attached to an opening provided in the approximate center of the can base formed in the convex shape of the can.

  Preferably, the twistable cap having a thread that matches the thread of the mouth is the opening and closing of the can, i.e., the first closure and (further) re-application of the cap and mouth threads. Blocking is possible.

  The screw cap may include a plastic inset gasket that contacts the mouth to hold the gas and liquid and reclose the container securely.

The air holes formed inside the closure release the internal pressure from the upper space of the can at the first stage of opening before the liquid contents are released from the can by drinking or pouring. Has started. The accidental risk of liquid ejection when opening the can is at least reduced.

  The re-occlusion closure may have a tamper evident portion near the bottom edge that allows the consumer to recognize whether the beverage can has been opened or has already been opened. Can do.

  Another type of filler or drinking mouth has been proposed. One is a rigid body that protrudes outward from the base of the can (claim 8). The other is a retractable design (Claim 25) that protrudes inward from the base of the can when closed, and protrudes outward when opened, or at least when it is about to be opened. To do.

  Further, the entire can which can be reclosed may be provided with a detachable storage container attached in the axial direction to the reocclusion closure portion (claim 26). This is located at the bottom standing end of the can.

  This containment may contain things such as chips, nuts, crackers or other snacks or promotional gifts, coupons or messages for the consumer. Moreover, this cup-shaped container may be used as a cup for those who do not want to drink directly from the can.

  Re-occlusion keeps the can contents fresh for extended periods of time when the can is re-occluded, for example, by maintaining a maximum value of residual carbonic acid within the re-occlusion time. Re-occlusion also expands the consumer's sanitary and safety benefits of packaging by preventing contamination, particularly insect entry into the beverage.

  The beverage can can be loaded (claims 14, 14a, 27). The cup or cap overlaps another can lid, which is attached under a “can under considation”. With this CUC can, can-type filling can be performed instead of bottle-type filling. The can is filled from a large open end without a lid in a safe and stable position on a cap or cup. The cap covers the mouth and covers a large surface when the can is raised in a radial direction and at least partially or intermittently around the peripheral edge (claims 13 and 14). . On the other hand, this edge portion is arranged below the stacked CUC cans, and allows the CUC cans to be loaded radially outside or radially inside the adhesive portion of the closed and closed can body. 27a). Therefore, even though the cans are stacked on top of other cans of the same shape, the edges are thus formed in accordance with the shape of the adhesive portion of the same can.

  The edge is a part of a cap component for re-occlusion (occlusion portion for re-occlusion), as in claim 8, 7 or 14a. The shape and dimensions of the edge are chosen to match the dimensions of the lid.

  The present invention includes several embodiments shown in four figures to enhance the understanding of the invention.

  Each figure is a side view (a) of a state where the flanges are closed (right) and a state where the flanges are not closed (left), an enlarged view near the base (b), and an exploded perspective view (c). A, b, and c (eg, FIGS. 1a, 1b, and 1c).

  The beverage can 1 shown in FIGS. 1 to 4 (each “a” to “c”) is an example manufactured from a metal thin plate by a DWI process. The beverage can 1 has a convex base shape 1.1 extending laterally from the central axis 100 of the can. The base shape protrudes from the inside 1i of the can to the outside. The cross-sectional shape of the can base that is hemispherically convex toward the outside may be designed with one, two, or three radii. The depth of the convex surface of the base is a ratio of diameter / depth between 2 and 33, preferably around 7. The base geometry can vary greatly. There is no step along the spherical shape at the base.

  The actual shape design is determined from a functional and aesthetic point of view.

  A circular opening 1e is opened at the can base 1.1 coaxially with the central axis of the can. The diameter of the opening is between 20 mm and 40 mm, preferably about 26 mm (+/− 10%). The peripheral edge part of the opening part formed in the opening part 1e is for attaching the mouth device 3 for pouring and drinking. The mouth device 3 is a part of the reocclusionable occlusion and requires other parts, i.e. at least a reocclusion occlusion member such as the cap device 4.

  The beverage can 1 is made from a thin plate of steel, aluminum, plastic, cardboard, or a combination of these.

  The DWI process uses a metal thin plate to produce a cylindrical container having a thin wall 1b and a thicker bottom 1d. The upper end portion 1c of the wall portion 1b is formed radially inward in the diameter reduction process, and has a small opening that communicates with the can interior 1i and is closed by the lid 2, as shown in FIG. 1a.

  FIG. 1 c shows the can 1, the lid 2 and the closure devices 4, 3 attached to the bottom end 1 d of the can in an exploded perspective view. FIG. 1 b is an enlarged view of the boxed portion of FIG. 1 a, showing the permanent attachment of the carrier 3 to the bottom of the can and the cap part 4 attached in the closed position. The two threads (the thread 4.1 cut in the socket 4a of the cap 4 and the thread cut on the radially outer surface of the carrier 3 formed in a cylindrical shape) can be opened (loosened). And interact for closed cans.

The can lid 2 is made of steel or aluminum. The lid 2 is the upper end of the closed can.
It is similar to the commonly used easy-open can end, but here it is not easy to open. That is, there are no score lines or tabs. The function of the end of the can is limited to closing and sealing after filling. The can lid is provided with a substantially flat end surface 2.1, which is connected to the wall of the chuck part via an inner edge near the countersink 2.2 (groove). When the wall portion of the chuck portion is not yet closed and is placed on the open contracted wall portions 1b and 1c, as shown in FIG. 1a (left side portion), the annular flange end portion 2. Terminates at 3. The flange end 2.3 is curled downward on its outer periphery. The inner surfaces of the flange end and the curl are lined with a sealing mixture (not shown). This sealing mixture, as shown in the right-hand part of FIG. 1a, after the can is filled, the (double) sealing part 2.4 has a flange end and a can body flange 2.5 (body bend). And the liquid and gas seal in the container is established.

  Due to the lack of a mechanism that can be opened easily, the flat part 2.1 of the can lid remains flat and untwisted. This makes this flat part an ideal base for expanding the advertising board of the container by printing additional information or images or labeling.

    The mouth portion 3 made of a single part and formed in a columnar shape is made of a polymeric thermoplastic material and includes a hollow cylindrical portion 3a. The outer part of the mouth is threaded with a thread of 3.1 / 2 to 25/2 revolution at one end. The screw thread is formed with a minimum length of 3, an interrupt of 3.2 along the axis parallel to the central axis 100 of the mouth 3 and preferably a maximum of 5, preferably 4. Yes. At the base of each thread break, there is a smaller glove that protrudes over the entire length of the thread break, with the shorter end of the two ends. The interruption is over.

  Two flanges 3.3 are provided radially outward at the end of the mouth 3 opposite the threaded tubular part. The two flanges are separated by a distance "" d "" corresponding to the plate thickness of the can body 1.1. After the mouth 3 is attached to the inside of the opening 1e of the can body, both flanges are heated to one of the heat-sealing materials applied around the hole 1e of the can body to which the mouth 3 is attached. Sealed.

  The flange of the mouth mounted so as not to be removed from the outside of the can body 1.1 can be tampered clearly with a u-shaped cross section via 5 to 15, preferably 12 tapped threads 3.4. It is connected to a ring (tamper evidence ring) 3.5. The operational function 4.2 for handling the tamper evident ring is part of the closure cap design and is shown in the corresponding description below.

  An alternative of mouth 3 is shown in FIGS. 3 and 4 where it is referred to as mouth 3 '. The mouth 3 'is composed of two parts. The two-piece mouth 3 'is designed in the form of a tube made of a polymeric thermoplastic material. The radially outer portion of the mouth is composed of a screw thread 3.1 'and a 360-degree sliding part 3.2' located inside. Also, the two-piece mouth 3 ′ is preferably circumferential so that it is adjacent to the two radial flanges 3.4 ′ used to attach the outer portion 3c of the mouth to the can body 1.1. Four to eight, preferably six, window-like openings 3.3 ′ formed at equal intervals in the direction are provided. The sliding part 3.2 'is arranged at the axial end of the mouth device 3c opposite to the mounting flange 3.4'. Two to three revolution threads are provided at the flange end of the mouth. The thread has several, preferably a minimum of three and a maximum of four or five interruptions 3.5 'in the longitudinal direction along an axis parallel to the central axis 100 of the mouth.

  A smaller glove is provided at the base of each thread break, which protrudes over the entire thread break and exceeds the break by the smaller length of the ends.

  Two flanges facing outward in the radial direction are provided at the end of the mouth 3 'opposite to the thread side. The flange located on the outer side of the mouth is extended to the annular protrusion 3.6 ′, and the cross section of the outer surface facing the axial direction of the protrusion 3.6 ′ is formed in a substantially circular shape. Yes. Both flanges are separated by a distance equal to the material thickness of the can body, as described above. After mounting the alternative mouth 3 'inside the opening 1e of the can base 1.1, both flanges are heated to either of the heat-sealing materials applied around the hole 1e of the can body. Sealed. By mounting in this manner, the opening end of the opening 1c is subjected to corrosion prevention treatment.

  The flange of the mouth located on the outside of the can body is connected to a tamper-evident ring 3.8 'with a generally u-shaped cross section through 5 to 15, preferably 12 thin threads 3.7'. is doing. The operational function 4.9 "for removing the tamper evident ring is part of the closure cap design and will be shown in the description below.

  The part 3b on the radially inner side of the mouth 3 'is further formed with a screw thread 3.9' on the inner peripheral surface and the outer peripheral surface, respectively. Both of these threads are located at the same end as the inner part of the mouth. The outer thread 3.9 'matches the inner thread 3.1' formed inside the outer part of the mouth. The inner thread 3.9 'formed on the inner side matches the thread formed on the inner peripheral surface of the closing cap 4 and its socket 4a, which will be described later.

    Inner mouth 3b continues to the end of the tapered portion 3.10 'where the thread is formed. The inner port is formed in the flat part of the closure cap and fits the tapered taper so that it is slightly narrower, with the closure system partially open, the two parts fit together and fasten together It is like that. These tapered portions open only the end portion of the inner mouth portion 3b that moves in the axial direction relative to the outer mouth portion 3c. This is when the inner mouth protrudes outwards and corresponds to the first stage of the process of opening the occlusion. The tapered portion is fixed again at the final stage of the movement of the occlusion process.

  An annular flange 3.11 'facing outward is provided at the end of the inner mouth that is away from the thread. This flange 3.11 'moves in a sliding bed of the outer mouth when opening and closing the recloseable closure part. The flange terminates the axial movement of the inner mouth at both ends of the sliding part.

  The end portions of the inner mouth portion formed in a flange shape are attached to the outer mouth portion in order to attach the inner mouth portion and mesh the circumferential flange 3.11 ′ with the space 3.2 ′. Designed with 6 and preferably 6 gaps 3.12 ′.

  The re-occluding screw cap 4 shown in FIGS. 1a to 1c is made of a polymeric thermoplastic material and is designed in a cylindrical shape. In the case of a circle, the diameter substantially corresponds to the outer diameter of the can wall 1b. The cap is provided with a cylindrical portion 4a in the center of the plane portion 4.4, and a screw thread 4.1 is formed inside the cylindrical portion 4a (female design). Both the thread and the diameter of the inner reclosable part are adapted to the corresponding part of the mouth 3 (male design). This portion is a socket 4a, 4.1.

  In addition, the cylindrical part inside the center is provided with a u-shaped part 4.2 which corresponds to the other of the tamper evident function of the reocclusionable closure system. The u-shaped part of the cap 4 is divided into 4 to 15, preferably 12 circumferential parts 4.3. Before the hook-shaped portion of the u-shaped portion of the cap 4 is hooked on the hook-shaped portion of the u-shaped ring 3.5, the cap 4 is screwed into the screw thread 3.1 so that the axial displacement is 4.3. By converting to the circumferential elastic strain of the part, only when the cap 4 is first attached, the u-shaped part of the cap 4 and the outside of the flange 3.3 of the mouth part 3 by the string part 3.4. Spring-type fixing is achieved by a u-shaped tamper-evident ring 3.5 connected to the part. FIG. 1b shows the locking part.

  '' Initially u-shaped '' tamper evident ring 3.5 can be forcibly opened and twisted by cutting a thin string 3.4 when the recloseable closure system is first twisted open It remains in a state of being caught by the u-shaped portion 4.3 inside the cap 4. A tamper-evident manifestation can be recognized by a sudden change in the resistance of rotation and a distinct sound meaning only at the first opening of the blockage.

  The horizontal horizontal portion 4.4 inside the cap 4 that can be twisted is provided with a gasket-like sealing plate so that the closed cap seals gas and liquid.

  The horizontal part 4.4 of the cap which can be twisted is substantially flat over the entire surface, has an edge 4.6 near the outer periphery, and leads from the flat part to the cylindrical wall 4.8 through the edge. As a part, it has the edge part 4.7.

  The diameter of the edge and the inclination of the rim are such that the closure cap 4 is stacked vertically on the outer shape of the can lid (so that the cans can be stacked), preferably radially outward of the sealing portion 2.4. Decided. Then, the cans with their contents can be stacked safely. The bottom edge portion of the cap 4 is adapted to be fitted to the closed opposite end portion (lid portion) and can be stacked up and down. This is called “a structure that can be stacked vertically with a lid shape (nestable with the lid geometry)”.

  A longitudinal groove 4.9 is provided on the outer side surface of the cylindrical wall portion 4.8 of the cap so that the consumer can easily open and close it. The surface 4c formed on the ridge faces the outer side in the radial direction, and is an example of the “easy to grasp” surface of the cap 4.

  A further embodiment of the reocclusion twistable cap 4 'shown in FIGS. 2a to 2c is similar to the reocclusion cap 4 described above, with the following exceptions.

  The outer peripheral wall surface 4.1 'of the cap 4' that can be twisted is designed in a step shape, and its diameter changes along the axial direction. The stepped design has a diameter equal to the can at one end and a smaller diameter at the other end in front of the edge 4.7. On the outer side wall, a minimum of 3, a maximum of 7, and preferably 5 key portions 4.2 are provided in the vicinity of the transition portion 4.3 from the small diameter portion to the large diameter portion. These key portions are for securing and mechanically fixing an optional storage container 5 having at least a thread Y, which will be described later.

  Also in this embodiment, the edge portion 4.7 is vertically stacked with the sealing portion 2.4 of another can.

  In addition, the cap 4 ″ that can be re-occluded is made of a polymeric thermoplastic material and has a rounded design, as shown in FIGS. 3a to 3c. The outer peripheral wall portion 4.1 ″ of the cap 4 ″ that can be twisted third has a cylindrical appearance in the axial direction 100 and has the same outer diameter as the beverage can. The outer peripheral wall part 4.1 "is connected to the edge part 4.3" of the cap which can be twisted via the edge part 4.2 ". The edge portion 4.3 ″ is also stacked in a sealed manner corresponding to the sealing portion 2.4 at the other end.

  At the edge portion 4.3 ", a minimum of three and a maximum of seven, preferably five, key portions 4.4" are provided. These key portions are provided to securely fix and fix an arbitrary cylindrical container 5 to be described later. The cap 4 ″ that can be twisted is also provided with a cylindrical socket portion having a screw thread 4.5 ″ on the outer surface on the inner surface of the center portion. Both the thread and the diameter of the internal reclosable part are adapted to the corresponding part of the telescopic mouth 3 '. The inner surface of the cap 4 ″ that can be twisted is axially opposed to the flat part, preferably with a tilted cross section, and the end of the stretchable part 3b of the mouth 3 ′, preferably with a tilt. An annular groove 4.6 '' is provided which geometrically fits the part 3.10 ''. The male and female taper portions fix the expandable mouth portion 3b to the cap 4 ″ that can be twisted when the screw-type cap is most screwed clockwise in the sealing direction. This frictional fixation allows the telescopic portion of the mouth 3 'to move out of the container when unsealed by a counterclockwise rotation of the cap 4 "that can be twisted.

  Further, a groove 4.7 ″ is provided on the inner surface of the flat portion of the cap 4 ″ that can be twisted, and this groove 4.7 ″ is the outer side of the flange 3.4 ′ of the mouth 3 ′. And an inlet seal 4.8 '' that is geometrically matched to an outwardly protruding protrusion 3.6 '. The sealing material and the protrusions tightly seal the gas and liquid when the reocclusionable closure is in the closed state.

  In addition, the flat portion of the cap 4 ″ capable of re-occlusion twisting is one of the tamper-evident tamper evident portions 4.9 ″, 3.8 ′ of the re-occlusion closure operating as described above. On the other hand, it has a portion 4.9 ″ that is initially u-shaped.

  The u-shaped part 4.9 ″ of the cap 4 ″ that can be twisted is divided into several parts in the axial direction, preferably between 4 and 15, or about 12. Only when the cap 4 is attached for the first time, it is initially u-shaped when connected to the outer flange of the u-shaped part of the cap 4 and the part 3c to which the mouth 3 'is fixed by the string part 3.7'. The tamper-evident ring 3.8 'is spring-loaded (elastic). The tamper evident ring is opened by cutting the string when the reocclusion closure is first opened and remains hooked to the u-shaped portion of the cap that can be twisted. A tamper-evident manifestation is recognized by a sharp sound that means only a sudden change in rotational resistance or the first opening of a blockage.

  The further embodiment of the reclosable cap 4 ′ ″ shown in FIGS. 4a to 4c has the exceptions described below, but is substantially identical to the cap capable of occluding twisting as described in embodiment 4 ″. It is.

  The twistable cap 4 "" has a reduced diameter flat section 4.1 "". The reduced flat part 4.1 ′ ″ provides the same characteristics as the twistable cap 4 ″, but is partly freed by a part 4.4 ′ ″ to match the diameter of the can body. It has a structure that reduces material. The twistable cap 4 ′ ″ comprises between 3 and 7, preferably 5 legs 4.2 ′ ″, at least some of which have the features of stacking containers and corresponding It has a key part 4.3 ′ ″ for fastening and mechanically fixing an optional container 5 to be described later by the latch part Y.

  In operation, the leg 4.2 '' 'corresponding to the edge 4.6 of the first embodiment is radially inward or outward of the mated other end of the underlying closed container. In order to have “loadable characteristics” by being stacked, it is adapted to fit geometrically to the sealing part 2.4. This is also applied to the other end of the same container so that all ends are the same.

  The added containment vessel 5 shown in FIGS. 3 and 4 is made of a polymeric thermoplastic material. The container 5 preferably has a cup-like appearance with the top opened and the bottom closed. The upper geometric shape matches the outer diameter of the bottom of the wall 1b of the container body. The bottom 5b of the container has the same shape as the caps 4, 4 ', 4 ", and 4'" that can be twisted in the geometric shape of 5b 'so that a container with a cup can be loaded on it. Has been.
