Description

Cardboard packaging with retention means for bottles

Background of the invention

This invention generally relates to Packaging items for use with items such as bottles, and more particularly it relates to openings in packaging of article with upper openings to grab items by the neck for improved retention.

Packaging of items with superior grip are known methods, several methods are known to retain a item inside the packaging. The present invention is sometimes related to a means of retention, and hereafter will refer to a "Sunburst" opening. In a sunburst opening, a plurality of tabs are arranged around the circumference of an opening.

The "Sunburst" openings are known; as shown in CA2339532, they comprise a circular opening and a plurality of radially extending cut lines from the opening. The cut lines create a plurality of tabs that create an annular series arranged around the opening circumference; in use these tabs are connect with a radial projection of the bottle or with a closure of bottle to retain the item inside the packaging.

You may want more retention and / or article stability within a "Sunburst" opening. The "Sunburst" openings known in the field may be limited in the degree of retention that they are able to supply. One possible reason for this may be that an opening "Sunburst" is constructed so that the annular series of tabs can create a large enough opening to allow move to a radial projection of the article. The radial projection is connected with the tabs to retain the article, however an undesirable consequence of this may be that only one Small part of each tongue is connected to the article. This mode can still allow the movement of the item at the point of contact and then the items are not always good sharp.

In addition, when the item is received, the material from which the "Sunburst" opening is constructed can weaken when bending. This weakening of the material can allow the movement of the tabs on that fold that further reduces the stability of the article within the opening.

U.S. Patent 5,960,945 to Sutherland reveals a packaging that holds the bottles by the designed neck to hold long neck bottles, on which they rest long support tabs are provided to extend up to a bottle flange and short tabs are provided for connect only with the side of the neck.

U.S. Patent 4,448,452 to Wood discloses a bottle conveyor by the neck using a type of semi-rigid material with great grip comprising a structure of frame in which a plurality of necks is formed, each neck has at least one pair of lifting tabs, inclined up to connect with a bottle flange and a pair of stabilization tabs fully formed with the frame structure to connect with a bottleneck.

The present invention seeks to overcome previous problems of the bouquet forming a "Sunburst" opening which increases the retention and / or stability of an article within  a packing

Detailed description of the embodiments preferred

Referring to Figure 1, a die 20 or a panel 20 of a die having an opening "Sunburst" 10, made of cardboard or similar folding material. The "Sunburst" opening 10 is required to receive an item 30, like a bottle, when the opening is contained within a cardboard die 20 as shown in figure 2. The opening "Sunburst" 10 comprises a first cut line 12 which is considerably circular. It is planned that in other modes of the invention the first cut line 12 could have a shape alternative. The first cut line 12 forms a first opening 14 in the die. The first opening 14 is preferably smaller than a closure of article C (shown in figure 2) or another radial projection of article 30.

In the preferred mode of the invention as shown in figure 1, a first eight-ring annular series main 24 are arranged around the periphery of the first opening 14. Each main tab 24 is defined by and separated from two main adjacent tabs 24 by two lines radial cutting 16. The radial cutting lines 16 extend outward from the first cut line 12 that defines the first opening 14. In total there are eight radial cutting lines 16. The outer end of the radial cutting lines 16 can define a periphery of a second opening 18 that is created at insert article 30, which has the diameter larger than the first opening 14. The first ring series of tabs main 24 may yield when article 30 is inserted into the first opening 14, thus forming the second opening 18 (as is shown in figures 2 and 3). The main tabs 24 are fold over a fold line 28. The diameter of the second opening 18 may be substantially equal to that of the closure of article C. as illustrated in figure 2. The second opening 18 allows the closure of article C to be inserted in the material of cardboard from a cardboard die 20.

Referring again to figure 1 the lines curved cutting 22 define the edges of secondary tabs 26. Curved cutting lines 22 are interposed between a pair adjacent radial cut lines or grooves 16. The tabs Secondary 26 form a second annular series. Cancel is used to describe the arrangement of the tabs of the first and second series 24, 26 and opening 14, it is provided that the opening 14 in other ways could be other than circular and therefore voiding should not be interpreted as just a circular arrangement The curved cutting lines 22 can extend considerably between the outer ends of the lines of radial cutting 16. Curved cutting lines 22 are terminated preferably on the circumference of the second opening 18. The curved cutting lines 22 are preferably semi-shaped. circular. The curved cut lines 22, the cut lines radial 16 and cutting line 12 define the first and second series annular of the main tabs 24 and the secondary tabs 26 respectively. The first ring series of tabs main 24 and the second annular series of secondary tabs 26 are arranged around the first opening 14. The secondary tabs 26 are / are at least partly made by the main tabs 24. The main tabs 24 and the secondary tabs 26 share a common periphery 18 along  which can be folded when article 30 is received by the "Sunburst" opening 10. The main tabs 24 are fold over the fold line 28. The secondary tabs 26 they fold over the fold line 32.

The second annular series of secondary tabs 26 can be folded along the periphery of the second opening 18 to allow the closing of article C. Once the closure of article C, or other radial projection, has gone through the opening "Sunburst" 10 the secondary tabs 26 try return to its original position until an edge 22, or other part, of the secondary tabs 26 fit a part of the article 30. Then they can reduce the movement of article 30 within the second opening 18, improving stability and / or retention of article 30. Article 30 is therefore in contact with the material 20 comprising the "Sunburst" opening 10 in two separate positions in relation to the plane containing the second opening 18.

Figure 2 shows the "Sunburst" opening 10 of Figure 1 constructed within a part of a panel of foldable sheet material 20 from which a packaging can be formed of cardboard. The "Sunburst" opening 10 of Figure 1 is shown connecting with article 30, for example a bottle, which has been inserted through it. An edge defined by the line cutting 12, or a part of the main tabs 24, is connected with the bottom of the closure of article C, which in this mode of embodiment is a crown cap, thus retaining article 30 inside the "Sunburst" opening 10. An edge defined by the cutting line 22, or the part of the secondary tabs 26, connect a part of article 30 below the point where the main tabs 24 are connected with the closure of article C. The main tabs 24 fold over the fold line 28 and the secondary tabs 26 return considerably to their original position.

Figure 3 shows a sectional view of a Article 30, for example a bottle, which is retained by the "Sunburst" opening 10 shown in Figure 1. The main tabs 24 connect to article 30 under the radially protruding article closure C. It is intended that the "Sunburst" 10 opening can connect any projection Article 30. The main tabs 24 and the tabs Secondary 26 are shown by connecting the item in positions different verticals or elevations in relation to each other, and with respect to the plane of the panel of foldable sheet material 20, thereby increasing the stability and / or retention of the Article. It is envisaged that in alternative embodiments in which a first or second series of ring tabs can be considerably in the same plane as the material panel folding blade 20.

A second embodiment of the invention It contains the features that are common to the first embodiment already described and therefore similar reference numbers are used to represent similar traits, with reference numbers start with 100 to differentiate the second mode of realization.

Figure 4 shows a second mode of realization of an opening "Sunburst" 110 seen in plan. A opening 114 is formed in a die 12 or a panel 120 of a die and defined by a first cut line 112. There are eight radial cutting lines 116 extending outward from the opening 114 defining a first annular series of tabs main 124 arranged around opening 114. A second annular series of eight secondary tabs 126 is created by eight cut lines 122 in substantially the same way as the main tab 124 from which they are made. This has the advantage that the secondary ring annular series 126 It has a concave edge that can contact the neck from the article. The first annular series of main tabs 124 and the second annular series of secondary tabs 126 share of again a common periphery 118 along which they can bend when an article 30 is inserted, the main tabs 124 are fold in zone 128 and secondary tabs 126 in the zone 132.

The sunburst opening 110 of the second mode of embodiment operates in a manner similar to that of the first mode of realization; A top of a bottle or other item is pushed into the first opening 114. When the bottle or other item are received in the sunburst opening 110, the tabs main and secondary 124, 126 are pushed out of the plane of material containing the sunburst 110 opening. The tabs main and secondary 124, 126 each fold of the plane of the opening sunburst 110 in the line area 118. Once the tabs 124, 126 are folded, a second opening 118 is formed. The second opening 118 is larger in dimension than the first opening 114, so that a larger part of an article can be deposited inside the sunburst 110 opening. The tabs main and secondary 124, 126 can each be distended, due to the natural tendency of the cardboard material to return to its original position, until the main tabs and Secondary 124, 126 contact the article inserted into opening 114. Connecting with the bottom side of an edge of an upper part of an article, the tabs 124 prevent the bottle from moving down and being released from the opening. The secondary tabs 126 contact the bottle received at the sunburst opening 110 in positions other than main tabs 124, thus providing a setting that restricts and limits the movement of an article. It is planned that each of the tabs on the second secondary series 126 can be designed differently from each other, or that even the size of adjacent tabs 126 can alternate between a shorter tongue and a longer tongue so that alternate secondary tabs would fit or connect with the bottle in different positions one in relation to the other. Also each of the adjacent tabs of the first series Main 124 can be of different size.

The present invention describes only two preferred embodiments, however it is envisioned that small changes could be made in the embodiments based on the concept of invention described herein. One such change would be the use of more or less eight cutting lines to form more or less eight circumferentially arranged tabs. Each of the first and second openings does not have to be circular, it can even be another shape that cannot be symmetrical, and can be irregular. The two openings may also be non-similar in shape although such an arrangement is preferable. The cutting line that defines the secondary series of tongues does not have to be the one described here, but it can be in any other way that satisfies its function, such as half of a hexagon that defines a rhomboid tongue. The present invention does not have to be limited to the nesting of two series of annular tabs but by employing other cutting lines, an additional series of tabs could be created to fit the bottle in different or radially or axially such positions. so that more than one secondary series of tabs is made from the first main series. It should also be evident that main and secondary tabs can be used with any combination of curvature, for example concave or convex at points 12. 22, 112
and 122.

It is recognized that as used here, the directional references as "top", "part bottom "," end "," side "," inside ", "exterior", "superior" "inferior" do not limit the respective panels to that orientation, but they simply serve to distinguish the orientation of several traits from each other. Any reference to the hinge connection should not be interpreted as necessarily in reference to a single line of fold only: the connection of hinge can be formed by one or more of the following, a scratch line, a break line or a line of fold.

Short fold lines 28 and / or 32, or short fold lines 128 and / or 132, described in the modes of preceding embodiments may be omitted while using a fold sheet material with the present invention. But nevertheless, when the fold lines 28 and / or 32 are used, or the lines of fold 128 and / or 132, they can be formed in the panel respective 20 in contact with the common theoretical peripheral line 18, 118 so that the fold lines extend at least partially along the common peripheral line and at least some tabs 24, 26, 124, 126 are connected so articulated to the panel by the fold lines.

Each of the short fold lines 28 and 32, and / or short fold lines 128 and 132, can be straight or curved in shape. Short fold lines 28 or 32, or short fold lines 128 or 132, may be circumferentially arranged around opening 14, 114 in angular spacing over the center of the respective opening 14, 114. Otherwise, the short fold lines 28 and 32, or 128 and 132 can be continuous (or connected together in a series) as shown in Figures 1 and 4 to form a single fold line circular.
