Abstract

  The carton for wrapping bottles (B) arranged in alignment has a keel structure, which is arranged between the rows of bottles. A keel structure is formed in the main panel of the carton and two keel structures are formed between the rows of bottles by engaging the two complementary portions (54,56; 154,156) with each other. A latching mechanism having complementary portions (54, 56; 154, 156) is provided so that the internal movement of the bottles contained in each row is suppressed.

Description

  The present invention relates to a carton for packaging a plurality of similar articles such as bottles. More particularly, the present invention relates to a top gripping type carton that is attached to the upper end of a bottle.

  It is well known that there is provided an upper end gripping type article carrier having an opening for receiving an article. The opening is usually a sunburst opening, which is a series of circumferentially arranged tabs that engage the top of the bottle or the underside of the crown cork to prevent the bottle from moving from the opening. Have The problem with such openings is where the tab engages the bottle, which can make the carton unstable, and the tab can be weakened by the unstable characteristics of the bottle in the carton. is there. Therefore, it is desirable to use a top gripping carton that limits the movement of the bottle within the carton. In many cases, it is preferable to use a carton in which the top panel protects the lid of an article having a lid that easily opens a hole, such as a yogurt container.

This type of carton is known. For example, Patent Document 1 (Foushee) discloses a carton having a keel structure suitable for holding and separating articles included in two rows. A problem associated with such cartons is that the top edge of one row of articles can tilt toward the top edge of the other row of articles. This makes it difficult to carry and this is a disadvantage of the carton. This problem is solved to some extent by adding a significant percentage of the side panels, but this requires uneconomical additional materials. Accordingly, it would be desirable to provide a top-end gripping carton that is sturdy and robust and that supports the articles held therein. It would also be desirable to provide an article carrier that limits the movement of articles held in a carton and that is easy to assemble and requires minimal material.

  In the following, with reference to the accompanying drawings, two exemplary embodiments of the invention will be described by way of example only.

  1 to 5 show a first embodiment of the present invention. Throughout these figures, the same reference numerals are used to indicate the same or the same features of the present invention. 6 and 7 show a second embodiment, where the same reference numerals are used to indicate the same parts of this second embodiment, but to distinguish the two embodiments, the reference numerals Further, “100” is added.

  FIG. 1 shows a blank 12 from which the carton 10 of FIG. 5 is formed. As can be seen from FIG. 1, the blank 12 is elongated in the vertical direction, and in this embodiment is formed of paperboard. However, the blank 12 can be formed from other foldable materials, such as a plastic sheet. As an aid to understanding the invention, FIGS. 2-5 show bottles “B” arranged in 2 × 3 rows.

  Referring to FIG. 1, the blank 12 is a continuous main panel for forming a carton wall, that is, a first top panel 60, a first side panel 62, a first bottom panel 64, and a first panel. Intermediate panel 66, adhesive panel 68, second intermediate panel 70, second bottom panel 72, second side panel 74, and second top wall panel 76. These main panels are connected so that one can be folded to the next along the intermittent fold lines 82, 84, 86, 88, 90, 92 and 94.

  Each of the first and second bottom panels 64, 72 includes three article receiving openings 50, each of which is shaped to receive a bottle “B”. The carton 10 of the present invention is particularly for use with a bottle “B” having a shape with an upper end dimension larger than the bottom dimension. Thus, each opening 50 is sized to receive the bottom of bottle “B” and engage the lower surface of the flanged upper end of bottle “B”. This is as shown in FIG.

  The first and second side panels 62, 74 and the first and second intermediate panels 66, 70 each have a series of molded openings 52 for receiving a portion of the flanged upper end of the bottle “B”. Prepare each. Furthermore, the first and second intermediate panels 66, 70 comprise complementary latching or locking mechanisms, which in this embodiment comprise at least one male tab 54, which is suitably It is configured to fit within the formed female opening 56. In this embodiment, the male tabs 54 are stamped out partly from the second intermediate panel 70 and partly from the second bottom panel 72 so that each male tab 54 is engaged. The part is formed by a cutting line having a predetermined shape, and each male tab 54 remains connected to the second bottom panel 72 so that it can be bent. Similarly, the complementary female opening 56 is formed from a tab 56 of a predetermined shape, the tab 56 being stamped from the first intermediate panel 66 and the first along the fold line or low strength line 57. The intermediate panel 66 is foldably connected. The tab 56 having a predetermined shape can be displaced from the surface of the first intermediate panel 66, so that an opening is formed in the first intermediate panel, into which the male tab 54 is inserted. it can. The male tab 54 and the female opening 56 are shaped such that the male tab can be interengaged with the female opening 56 and can be latched (fixed) within the female opening 56. Yes.

  In the second embodiment shown by the blank 112 of FIG. 6 and the semi-finished carton of FIG. 7, the complementary latching mechanism has a different configuration. The male tab 154 has a shape that can be bent around the low-strength line 143 disposed at the center thereof. The male tab 154 is connected to the second bottom panel 172 in a foldable manner via bent fold lines 158 and 159. Further, a female opening 146 is formed in part by displacing the first complementary shaped tab 156, which is displaceable from the surface of the first intermediate panel 166 and It is connected to the panel 166 along the fold line 157 so as to be foldable. In the second embodiment, the first tab 156 comprises a radial recess formed by a semi-circular line 145, which is positioned on the bent male tab 154, and the male tab 154 is Hold in the opening 146. In the second embodiment shown in FIG. 6, the female opening 146 is formed by a single displaceable tab 154, but it is conceivable to provide a second displaceable tab 146, which is also the first displaceable tab 146. Although it is formed by punching from the intermediate panel 166, it is connected to the carton along the fold line 182 so as to be foldable. In this further example, the two displaceable tabs 156 and 146 cooperate to hold the male tab 154 in a latched (fixed) state.

  The latching mechanism of the first and second embodiments will be described in more detail with reference to the structure of the keel structure formed in the upper end grip clip 10 of the present invention. The keel structure and the latching mechanism of the present invention will be described in relation to the upper end gripping clip type carton. From the above description, the keel structure and the latching mechanism are used in other types of cartons. It will be apparent to those skilled in the art that the present invention should not be construed as limited in its application to the cartons described herein, which have been treated only as examples of one application.

  Turning to the assembly of the carton 10 of the first embodiment, a series of folding and bonding steps are required, which can preferably be performed in a linear device, whereby the carton 10 and There is no need to rotate or turn the blank 12 over. The folding process is not limited to that described below and can be modified according to specific manufacturing requirements.

  In order to form the carton 10 from the blank 12, the bottle receiving openings formed in the first and second bottom panels 64, 72 respectively for six bottles “B” arranged in two rows of three each. 50 and aligned. Subsequently, as shown in FIG. 2, the blank 12 is lifted substantially vertically. Subsequently, the two rows of bottles are brought closer together and the blank 12 is folded about the fold lines 88 and 86. Thus, the first and second intermediate panels 66 and 70 are rotated from the surfaces of the first and second bottom panels 64 and 72 and brought close to each other. Adhesive panel 68 or keel structure top panel 68 abuts each other at the edge where first and second intermediate panels 66, 70 are defined by fold lines 86 and 88 (in this state, adhesive panel 68 is bottle "B Until the upper end portion of the bottom panel 64 is placed in flat contact with the upper end portion of the bottom panel 64, 70. When the first and second intermediate panels 66, 70 are moved together, the male tab 54 engages a correspondingly shaped tab 56, and the male tab 54 is received within the female opening 56, This can be used to displace a tab of a predetermined shape from the surface of the first intermediate panel so that the first and second intermediate panels 66, 70 are hooked together. Thus, the adhesive panel 68, the first intermediate panel 66, and the second intermediate panel 70 form a keel structure having a triangular cross section as shown in FIG.

  Each of the predetermined shaped openings 52 provided in each of the intermediate panels 66, 70 engage a portion of the bottle “B” and allow this portion to protrude into the triangular cavity of the keel structure. As a result, the adhesive panel 68 can be placed on the upper surface of the bottle “B”. The adhesive panel 68 has a first flange-like edge sandwiched between the top panel of the carton and the lower edge of the opening 52 (of the bottle housed in the carton 10 adjacent to the keel structure). It can be fixed to the upper surface panel 60. In this way, the predetermined shaped openings 52 provided in each of the first and second intermediate panels 66, 70 also constrain and limit movement of the bottle “B” within the finished carton 10. To help.

  To accomplish the assembly of the carton 10 around the bottle “B”, the first and second side panels 62, 74 are folded 90 ° upwards about the fold lines 82 and 92, respectively, as shown in FIG. . The openings 52 of the first and second side panels 62, 74 engage the upper and lower edges of the flanged portion of the bottle “B”, respectively. Subsequently, the second upper surface panel 76 is bent around the folding line 94 so as to be in a plane contact state with the upper edge of each adjacent bottle. Subsequently, an adhesive is applied to the outer surfaces of the second top panel 76 and the adhesive panel 68. Finally, the upper surface panel 60 is bent about the bending line 80 and brought into a plane contact state with the second upper surface panel 76 and the adhesive panel 68. By doing so, the first upper surface panel 60 is fixed to the second upper surface panel 76 and the adhesive panel 68, whereby the assembly of the carton 10 is completed (this state is shown in FIG. 5).

  The carton 10 thus obtained can reliably wrap (hold) a row of six bottles and suppress the movement of the bottles in the carton 10. Inward movement of the bottle upper end can be blocked by the keel structure, and outward movement can be blocked by both the complementary latching mechanism and the first and second side panels 62,74. The bottom-loading carton 10 can provide a stable and robust carry for a row of bottles “B”, which can be easily assembled around the bottles in a linear device. By pre-cutting the folding lines 82, 84, 86, 88, 90, 92, and 94, the assembly of the carton 10 is facilitated.

  Keel structure (which mainly comprises a first side panel 66,166, i.e. a first intermediate panel 66,166, a second side panel 70,170, i.e. a second intermediate panel 70,170, and a top surface). Panel 68, 168, comprising adhesive panels 68, 168), consists of male tabs 54, 154 and female openings (female openings are provided by displaceable tabs 56, 156). It is held together in the carton 10 by a complementary interengageable latching mechanism realized by one or more pairs.

  In the second embodiment, the male tab 154 is bent about the central fold line 143 so that the apex or upper end of the male tab 154 is a substantially semi-circular recess or recess formed in the tab 156. It is fixed in the groove 145. Further tabs 146 can be provided, and if tabs 146 are provided, they can have radial (semi-circular) protrusions that are similar in shape to the radial (semi-circular) recesses of tab 156, thereby providing The bent male tab 154 has a tab 145 that rests on the upper surface of the male tab and a position upstanding from the surface of the first side panel 166 of the keel structure to the bottom panels 164 and 172 of the carton And the disengageable tab 146 is held in an engaged position locked. A second displaceable tab is not required to securely latch the male tab 154 within the opening 146, but in a further example of the present invention, the first bottom panel along the fold line 184. Clearly, a second displaceable tab 146 foldably connected to 164 can further assist the engagement of the male tab 154 within the female element of the complementary latching mechanism. It is.

  According to such an arrangement and configuration of the latching mechanism, when the male tab 154 is pressed against the two tabs 156 and 146, thereby placing it in the opening 146, the two tabs 156 and 146 are moved to the first one. By displacing from the surface of the intermediate panel 166, a female opening is obtained. The male tab 154 cannot be returned through the female opening. Because of the natural elasticity of the material from which the latching tabs 156, 146 are then formed, the latching tabs 156 and 146 are directed toward their original position, ie toward the surface of the first intermediate panel 166. This is because the female opening is partly reclosed by reversing. In this way, the male tab 154 is prevented from being removed from the opening. Although the second displaceable tab 146 is not provided in the second embodiment, the natural resilience of only the first displaceable tab 156 partially recloses the female opening 146 and This is sufficient to prevent the male tab 154 from detaching therefrom.

  For both the second embodiment and the example foreseeable, a fold line 143 is provided to bend the male tab 156 into a “H” or “V” shape. The male tab 156 fits within the radial (semi-circular) recess 145 of the first displaceable tab. Where a second displaceable tab 156 is provided, the radial (semi-circular) protrusion of the tab 146 is first provided below the male tab 156 and in the “V” -shaped male tab. With the three tabs 146, 154 and 145 fitted into each other, the male tab 154 pulls the other two tabs 146 and 156 (when moving back toward its original position) This closes the opening formed in the first intermediate panel, thereby constraining the male tab from further back, so that the intermediate panel or first and second side panels of the keel structure Is maintained in an upright state. Further, if the tab 146 is not provided, the first displaceable tab and the male tab 156 are arranged together enough to obtain a similar locking action.

  It will be apparent to one skilled in the art that modifications may be made to the above without departing from the scope of the invention as set forth in the claims. For example, the carton size may be suitable to accommodate more or fewer items that may be included in alternatives. The size and shape of the opening can be varied to accommodate other shaped articles and the carry can be configured as a wraparound carton with no openings formed in the bottom wall panel. The portable device may also be configured to include a transport means such as a hand opening formed in the top panel, or in fact, may include a handle panel extending upward from one of the top panels. . Furthermore, the carton is not limited to having one keel structure, for example, if the bottles are arranged in 3 × 3 rows, employ one or more additional keel structures and latching mechanisms. be able to. It will be appreciated that in other embodiments of the present invention, the keel structure may have a cross-section other than a triangle without departing from the scope of the present invention. The arrangement of the male and female portions of the latching mechanism can also be varied in other embodiments of the invention, and each intermediate panel includes one of the portions of the complementary latching mechanism, Obviously, the intermediate panel may have a mutual part aligned therewith.

  The latching mechanism and keel structure described herein can be applied to other types of cartons, and the latching keel structure and / or latching mechanism is not limited to the upper end gripping type carton. Is clear.

  As used herein, orientation references such as “top”, “bottom”, “end”, “side”, “upper” and “lower” constrain individual panels to that orientation. It should also be understood that they merely serve to distinguish these panels from each other.

  It should also be understood that references to foldable or foldable connections should not be construed to necessarily mean only a single fold line. Indeed, it is clear that the foldable connection (hinge connection) can be formed from one or more of perforations, breakable lines or fold lines without departing from the scope of the present invention.
