Description

The present invention relates to a closed type bottle container for packaging, in particular for preventing breakage caused by adjacent bottles hitting each other.

U.S. Patent No. 3,904,036 discloses a container for bottles. It consists of a top and a bottom wall and side walls connecting them, each of which is composed of a vertical bottom part and an upward sloping reinforced top part. Both the lower and upper parts of the side walls are connected by fold lines with transverse panels, between which horizontal, triangular stiffening ribs are formed. The upper wall of the container is also connected on both sides by fold lines with flaps folded from below, covering the sidewall sheets after the container is assembled. Also, the bottom wall of the container is connected by fold lines with flaps bent upwards covering the outer side wall panels and the top wall, and it is also provided with the so-called False cut in the bottom of the container.

The disadvantage of this solution is the necessity to carefully adapt the structure and dimensions of the container cut to the shape and dimensions of the bottles each time. Otherwise, the bottles will easily break if they strike each other during transport in the container.

From the Canadian patent specification No. CA 1166211 there is known a container for drinks bottles also composed of a bottom wall, with fold lines connected thereto by side walls, and with a fold line connected to one of these side walls - the top wall. In addition, the sidewalls are subdivided into upper and lower portions and divided by fold lines with spatially shaped, reinforcing side panels. The bottom wall, on the other hand, is connected by fold lines to the side flaps, which connect by means of narrow, folded corner bays to said side panels of the side walls. In order to properly shape the elements of the container, the blank is provided with shaped openings at the corners of the bottom wall.

The inwardly projecting corner reinforcing elements limit the possibility of movement of the bottles in the container, however, in the case of deviations of the shape and size of the bottles from the pattern for which the pattern was designed, this limitation turned out to be insufficient, so that the bottles break during transport.

The object of the invention is to construct a container for bottles free from the drawbacks and inconveniences of previously known containers by preloading the bottles contained in the container.

This object is achieved with the structure of the container according to the invention, consisting of a rectangular top, bottom and side walls, each of which is composed of a bottom part and an inwardly inclined top part. The top wall of the container is connected by fold lines coinciding with its side edges with the top panels, and the bottom wall is connected by fold lines coinciding with its side edges with the lower side panels.

The essence of the invention consists in the fact that the lower parts of the side walls are connected on both sides by fold lines, inclined at a slight angle to the cut axis, with stiffening elements provided with a surface incision for their spatial shaping, while the upper parts of the side walls are connected on both sides by fold lines parallel to the cut-out axis. the axis of the blank with stiffening elements, provided with surface cuts for their spatial shaping.

Each stiffening element connected to the upper part of the side wall is in this case separated from the respective sealing element connected to the lower part of the side wall by a slot and an incision.

The surface cut of the stiffening elements connected to the lower part of the side wall is a coaxial extension of the cut line passing through the cut point of the upper parts of the side walls of the surface cut of the stiffening elements connected to the upper part of the side wall.

The surface incision of the stiffening elements connected to the lower part of the side wall, on one side, reaches the point of intersection of the fold line, and on the other side, it joins a sharp inclined, forking surface incision.

The stiffening element connected to the upper part of the side wall is separated from the upper panel by an opening having the shape of a right-angled triangle, the side of which lies along the fold line of the upper wall of the container, and by a surface incision further extending this fold line.

The surface cut of the stiffening element connected to the upper side of the side wall forms an extension of the hypotenuse of the triangular opening separating the stiffening element from the upper wall of the container.

In the assembled state, each of the stiffening elements is spatially formed by folding along the line of surface incisions and extends from the outer edge of the container towards the interior, while each of its lower side panels is glued to the space-shaped stiffening elements below it.

In a variant of the solution of a container for bottles according to the invention, the lower parts of the side walls are connected on both sides by fold lines with stiffening elements having a triangular outline shape and provided with surface cuts for their spatial shape, while the upper parts of the side walls are connected on both sides by fold lines with the stiffening elements, having a rectangular outline and provided with surface cuts for their spatial shaping. In this variation of the container, each stiffening element connected to the top of the side wall is separated from the stiffening element connected to the lower part of the side wall through a slot.

On the other hand, the fold line connecting the stiffening element with the lower part of the side walls is a broken line, the first part of which runs perpendicularly to the fold line connecting the lower part of the side wall to the bottom wall, and its second part, which is preferably a surface cut and inclined at an obtuse angle to the first portion extends to the intersection of the fold line joining the lower portion and the upper portion of the sidewall with the fold line joining this upper portion of the side wall with the stiffening element.

The surface incision of the stiffening element connected to the upper part of the side wall extends to the intersection of the fold line connecting this element with the upper side wall part with the fold line joining the upper part of the side wall with the adjacent upper wall at an acute angle with respect to the fold line to the point of intersection with a surface cut of the stiffening element connected to the lower part of the side wall lying in the area of the slot.

Each stiffening element connected to the top part of the side wall is further separated from the top panel by a rectangular hole contour based on one of the legs on the fold line, which is an extension of the fold line connecting the top part of the side wall to the top wall and to the overlap panel, and additionally provided with a surface incision, constituting an extension of the hypotenuse of the opening separating this stiffening element from the panels.

In the assembled state, each of the stiffening elements is spatially formed by folding along the line of surface incisions and extending from the outer edge of the container towards the interior.

The bottom wall of the container is further preferably provided with a system of symmetrically spaced U-shaped openings.

Moreover, the stiffening elements 15 and 23 and 17 and 27 are provided with respectively fold lines 30 and 32 and 31 and 33 lying along one straight line.

Due to the three-dimensional design of the stiffening elements 15, 23 and 17 and 27 by folding them along the fold lines 30 and 32 and 31 and 33, the bottles in the container are firmly seated and held in their position by the container elements in a pre-stressed state.

In a further part of the container blank, the upper part of the side wall 8 is connected along fold lines 36 to the lower part of the side wall 35 and, moreover, by fold lines 38 and 41 it is connected on both sides with the stiffening elements 37 and 40, respectively. The stiffening elements 37 and 40 have the same outline. and surface cuts as previously discussed stiffening elements 15 and 17.

Also connected on both sides to the lower part of the side wall 35, along fold lines 43 and 45, the stiffening elements 42 and 44 have a contour and surface cuts like the stiffening element 15. The stiffening element 42 is hereby partially separated from the stiffening element 37 by a slot 42a and a small incision. 42b, and the stiffening element 44 is partially separated from the stiffening element 40 by a slot 44a and a small incision 44b.

Downstream of the container blank, the lower portion of side wall 35 is joined along fold line 48 to the bottom wall 47 of the container, which in turn is joined along fold line 50 to the bottom side panel 49 and along fold line 52 to the bottom side panel 51, and also in its lower part along fold line 54 with an adhesive flap 53.

The blank in the form shown in FIG. 2 differs from the flat blank according to FIG. 1 in that the lower part of the side wall 21 with the stiffening elements 23 and 27 is folded forward along the fold line 22.

On the other hand, the blank in the form shown in Fig. 3 differs from its embodiment according to Fig. 2 in that a portion of the side wall 6, the handle 14 and the upper part of the side wall 8 together with the lower part of the side wall 21 are raised and then folded downwards along the lines. fold line 36, and a layer of adhesive is applied to the flap 53. At the same time, the stiffening elements 37 and 40 and 15 and 17 overlap the stiffening elements 42 and 44 and 32 and 27, respectively.

In order to give the container its final folded shape according to Figure 4, the handle 14 has to be lifted from the position shown in Figure 3 and the lower portions of the side walls 21 and 35 are given a vertical position perpendicular to the bottom wall 47.

Loading of the bottles into the container can take place from either end or both ends, with the stiffening elements 15, 23, 17, 27, 37, 42, 40 and 44 being then inserted into the container.

The top panels 2 and 4 are folded downwards along fold lines 3 and 5, and the bottom panels 49 and 51 along fold lines 50 and 52. Then the glued surface 2a of the upper panel 2 and the glued surface 4a of the top panel 4 are glued to the outer edges, respectively lower side panels 49 and 51. These operations will result in the final shaped and loaded container taking the form shown in Figure 4.

The container in Figure 5 is partially sectioned side view showing fold lines 30, 32, 25 and 26.

A variant of the container according to the invention, shown in Fig. 8, is a corrugated cardboard blank consisting of a top wall 101 provided with a handle 102 and U-shaped cutouts 103, 104, 105 and 106, connected to the top wall 101 along a line. folds 108 of the top panel 117 and joined thereto along fold line 110 of the top panel 109. Furthermore, the top wall 101 is connected along fold line 113 to the top of side wall 111, which in turn is connected along fold line 112 to the bottom of the side wall 110a.

In a variation of this, not shown, the upper part of the side wall 111 may be flush with the lower part of the side wall 110a after the container is assembled. In this case, the fold line 112 is omitted and both portions 111 and 110a are formed as one panel.

In addition, cutouts 114 and 115 are provided in the upper portion of side wall 111.

This type of container according to the invention is provided on both sides with stiffening elements 116 connected to the top panels 109 and 107, respectively, along the fold line 117 and provided with surface incisions 119, delimiting the triangular sheets 118 of these elements 116.

The triangular panels 118 of the stiffening elements 116 are joined along a fold line 120, perpendicular to the fold line 112, to the top of the side wall 111.

Triangular-shaped stiffening elements 122 and 124 are connected to the lower part of the side wall 110a along a forking fold line 123, 125, 126 in its portion 123 perpendicular to the fold line 112 and parallelly shifted from the fold line 120. A small, triangular stiffening element 124 is formed between the fork 125, 126 of the fold line 123 which, together with the cutout 130, 131, is intended to facilitate manipulation of the stiffening elements during assembly and loading of the container. The cutout 130 may also be longer than that shown in Fig. 8 and extend up to the intersection 127 of fold lines 120 and 126.

The stiffening elements 116 and 122 are interconnected by a web 132 which helps to keep the elements in position while the container is being glued. The webs 132 can also be eliminated from the structure of the blank, and the cutouts 131 then completely separate the stiffening elements 116 and 122.

During assembly of the container, the stiffening elements 122, folded at right angles, contact and adhere to the inner surface of the lower portion 110a. In contrast, the element 124 presses the stiffening element 122 against the bottom of the corner bottles.

The stiffening assembly at the other end of the container is the same as discussed above and consists of a stiffening element 116 with triangular panels 118 and a stiffening element 122 and 124.

The lower portion of the sidewall 110a is connected by a fold line 135 to the lower wall 136 provided with openings 137, 138, 139, 140, 141 and 142 which facilitate handling of the container during assembly and filling. Further, the bottom wall 136 is connected on both sides along fold lines 145 and 147 to the bottom panels 144 and 146, respectively.

Shown on the right side of Fig. 8 and connected by fold lines 135 to the bottom wall 136, the side walls 110 and 1 and the stiffening elements 122 and 116 are symmetrically of the same structure as discussed above, shown on the left side of Fig. 8, side walls 110 and 111 and stiffening elements 116 and 122. The difference between the structure shown on the right side of Fig. 8 of the blank portion is that the upper portion of the side wall 111 is connected along a fold line 151 to an overlap flap 150, which in turn is connected on both sides along fold lines 153 to panel 152, and on the other hand along fold line 155 with panel 154. Further, tab 150 is provided with U-shaped notches 156 and 157 (Fig. 8) and an adhesive partially cut reinforcement panel 158 connected to the tab 150 fold line 159.

During the assembly of the container, the reinforcement flap 150 is lifted and folded to the right along the fold line 159 and is adhered to the inner surface of the overlapping panel 150. The wall 111 is then lifted, along with both stiffening elements 116, with the panels 150, 152 and 154, and folded to the left along the fold line 112, and glue is applied to the panels 150, 152 and 154. Finally, the left side wall 111 is lifted, along with the stiffening elements 116, with the wall 101 and the panels 117 and 109, folding them to the right along the left side. fold line 112, and the lap flap 150 adhesives to the inner surface of wall 101 (Fig. 9).

As a result of the above assembly steps, the container is shaped into its final but open form and can be loaded from one (Fig. 10) or both ends. Then the upper and lower panels are glued together as shown by the dotted surfaces in Fig. 12, the stiffening elements are positioned accordingly and the container takes the final form shown in Fig. 7.
