Technical field

The present invention is about paperboard carriers, and corrugated board carriage preferably, this carriage are used for being placed at least two row and having bevelled top and the circle tube tank of the top cover of the circular edge that band is outstanding links together a plurality of.This carriage is made by flat ground paper, concerning each wants the bonded assembly jar, this ground paper has two mutual relative basic cracks of arc that be, goes up, carriage and jar are linked together and when forming package component when carriage is assembled in a plurality of jars, below the projecting edge that the outward flange in crack is engaged on jar.

The present invention is also about the method for jar with the flat blank of the cardboard of the carriage blank flat with assembling cardboard.

Background technology

Circle tube tank is used for the beverage of food industry, these beverages such as mineral water, beer and soft drink.In order to carry a plurality of jars, package component is provided, this assembly can comprise 10 jars of 2 row.Many dissimilar package components had been arranged in the past, and they can be mentioned and handled a plurality of jar by client.

Plastics have been used for the package component device, for example twine a plurality of jars of packing with plastic sheeting, or adopt interconnective plastic ring around jar.Yet these package component installation cost height, and can cause environmental issue.The jar of another type is made by cardboard with carriage, because they had both had the advantage of environmental protection aspect, has commercial value again, therefore adopts.In addition, also adopted the combination of plastics and cardboard to be used as the package component device.

Consider a large amount of uses of beverage packaging assembly and with a large amount of jar that these packings or kit form are sold, comprise that the cost of the individual packaging of material and assembly cost is a very important factor to the cost of the package component sold.Therefore, the less variation of package component cost is very important.In addition, it is very important can clearly seeing and discern packaged products in package component.

As an example, at US-A-3, disclose in 194,476 a kind of resemble award with the carriage of paperboard carriers or the winding band that extends around one group of jar.The carriage cost height of this winding band, and on continuous manufacturing line, encase a plurality of jar also very complicatedly, further shortcoming is that client can not discern packaged products at an easy rate.

The paperboard carriers that also has one type is as at US-A-3, describes in 094,210, and it should be used for one group of upside of wanting the bonded assembly container.This carriage is made by flat fluting board blank, this blank has two opposed U-shaped cracks that are used for wanting each container of bonded assembly, fold into the sidepiece of container downwards by the side-flange of blank, the shoulder below that makes the outward flange in carriage crack be engaged on container is assembled on this group container flat blank.Yet, throw off for the mutual edge in crack and the shoulder of preventing when mobile between container, must add additional corresponding carriage in the bottom of container.The shortcoming of above-described carriage is: it only can be used for the single file container, material cost is high and make the assembly more complicated with two carriages.Further shortcoming be along container side downwards the side-flange of outstanding carriage can be at an easy rate colluded and tangle by adjacent package component or other member, thereby flange is forced upwardly, the edge in crack and the disengagement of container shoulder.

A kind of similar jar carriage is disclosed in EP-B-0496807.This carriage comprises the otch of two relative arc cracks that are used for each jar and the weak point that radially extends from above-mentioned crack, and a plurality of flaps that are formed between the otch are engaged on the outstanding neck below of jar.On every side of carriage, be provided with folding grippale tabs, make the user grasp or to mention and jar carriage together.Verified, this disclosed carriage can not be engaged on carriage on the jar fully securely, and is all the more so when especially adding hoisting force on the recess that grasps the carriage sidepiece.This carriage has the fold line that centering is settled, and when hoisting force was added on the extracting recess in the carriage opposite side, this line was as " hinge ", like this jar separately and have a tendency with the carriage disengagement.In addition, lateral plate be subjected to upward to hoisting force the time and stressed, this just further increases a carriage and a jar danger of throwing off.

Summary of the invention

The objective of the invention is to solve the problems referred to above by the carriage that a kind of a plurality of jars of usefulness are provided, these a plurality of jars, at least be positioned to two row, this carriage can be fixed firmly on the jar, thereby connect, lock and the support jar, and a kind of package component is provided, this assembly can mention under the situation dangerous without any disengagement and dispose, but this carriage saving in material also can be easy to and be added to effectively and be assembled on a plurality of jars.

Can reach this purpose according to the present invention, wherein adopt aforesaid jar to use carriage, jar the corrugation ground paper of carriage and the method for assembling carton blank, feature of the present invention limits in the appended claims.
