Description

The asymmetric casket of rolling sheet material

Technical field

The present invention relates to sheet material distribution casket (dispensing carton), it is used for the sheet material such as polymer sheet, metallic paper and other sheet material, more specifically, is used for the sheet material that contains and protect that those are applicable to the various article that comprise perishable material.The invention still further relates to such casket, its permission is rolled up end load (end-loading) in casket with product in manufacturing process.

Background technology

The containing and protecting of various article, and be known to widely in the prior art such as the used flaky material of preservation of the perishable material of food.Such material can be used for twining article independently and/or can be used for forming the airtight of semienclosed container.

Class in such material now commonly used comprise form thin, be the material of various compositions of the submissive width of cloth sheet of two dimension basically, it provides with the form of volume usually.The common example of these materials is polyvinylchloride (PVC), polyvinylidene chloride (PVDC), polyethylene (PE), polypropylene (PP), aluminium foil, band coating (be coated with cured etc.) and the paper or the like of band coating not.Recently Kai Fa the another kind of material that is used for similar application comprises three-dimensional flexible web, and this width of cloth sheet is included at least one lip-deep active substance such as adhesives, and this material is protected by the 3 d surface topography of base material and do not contacted with the external world.

For such material, normally provide a casket to hold and to distribute these sheet materials.The casket of conventional confguration is usually by the paper board material manufacturing, and this paper board material is cut and is folding to form box like structure when edge and flap are closed each other.This sheet material often by on plastics or paperboard tube to form a core tube.Many kinds of casket materials and sheet material/volume structure can be used for various application.

In order to provide attractive in appearance and box shape that be easy to grasp, especially for large diameter product volume, it is protruding to make at least one side of casket have an angle that reduces, for example hexagon or octagon, this more presses close to a curved surface, thereby more presses close to the curved shape of customer's hand when grasping this casket.Yet the hexagonal of symmetric shape or anistree casket are easier to upset because of the cross-sectional plane of its more approaching circle simultaneously.Therefore, need to keep some by having protruding square in big angle or stability that the rectangle casket provides, with the opposing upset.

Casket such as most of asymmetrical shapes of half hexagon (having half hexagonal section and half square-section) is not suitable for end load box packing machine (end loading cartoner), and needs to use the top-loaded design.More specifically, the end load box packing machine depend on empty boxes by from mutually folding and along the glue-line bonding to form the ability of the tubular/column structure that flattens, this structure can be erected into its required final cross-sectional plane then, and the product volume inserts from an end, and the sealing of the flap of this end gummed.If casket can not be assembled into such flattening and then because of the upright tubular structure of the geometric configuration of side, then casket must assemble and roll up by a side (normally " the top side ") product of packing into allowing before final assembling, rather than brings in insertion by one.The top loader is slower than end-loader usually in operation, cause little output, and it is not too reliable usually.

Most of casket of the prior art lacks and allows the customer to roll up the head that exposes the material roll sheet from the outer buttons of the casket product volume of changing the line of production to rotate this, or rotates this and roll up and unnecessary sheet material rolled and feature in the casket is regained or taken in the end of width of cloth sheet to casket.Many caskets rely on the weight of product volume self to keep its location in casket, and this twists in the use and can move about in casket.

Common casket also adopts the flap of locking or other device to come to keep between various uses the casket lid to be in closed state in the prior art.Yet such device is in use more fragile usually and/or be difficult to make, so some caskets have saved such closed block fully.

Therefore, need provide a kind of asymmetric casket, it is applicable to the end load box packing machine.

A kind of like this casket need be provided, and it has additional parts and the releasable lid closing appliance of being convenient to location, product volume end.

Also need to provide a kind of like this casket, it can easily and economically be made, and can be used for holding and distributing sheet material.

Summary of the invention

The invention provides a kind of asymmetric casket, to hold and to distribute the sheet material volume.Casket has a major axis, and has erectility and flat form.Casket forms a tubular construction when upright, it has the asymmetric polygon cross-sectional plane that is formed by a plurality of smooth basically side plates.Casket has the fold line of being determined by the intersection of adjacent side plates, and by folding this casket forms the structure of substantially flat and can be folded into flat form at two fold line places.

The specific embodiment

Fig. 1 shows according to casket 10 of the present invention, and it is suitable for holding and from rolling up the width of cloth sheet 20 of 30 distribution sheet materials.Casket 10 comprises 1, two end plate 2 of base plate and 3,

side plate

4,5,8 and 9, and the lid 25 that comprises top board 7 and flap 15.In the embodiment shown, flap 15 anterior side plate 5 of lap at least when lid is in sealing and arranges.The gusset 6 of lid 25 every ends helps flap 15 is maintained under the state vertical with the top board 7 of lid 25.

Plate

1,4,5,7,8 and 9 all is used as " side " plate, and by fold line be connected to each other (or for

plate

5 and 15, being the overlapping relation of the toe lateral that forms the substantially flat that is called compound front panel 5/15 herein) have the tubular construction of polygon cross-sectional plane with formation.This tubular construction is by end plate 2 and 3 sealings, to form the osed top casket.The line of centers (being shown " CL " among Fig. 5) of product volume has been determined the longitudinal axis of casket, and " side " plate all is arranged essentially parallel to this longitudinal axis, and end plate is substantially perpendicular to this longitudinal axis.

Casket 10 also comprises the blade 40 of the required part that is used to cut off sheet material.In current preferred (but only being illustrative) structure shown in Figure 1, blade 40 is positioned on the terminal edge 16 of flap 15, makes the tooth of blade stretch out at least slightly and exceeds the edge of flap, and is overlapping with anterior side plate 5.In structure shown in Figure 1, blade is fixed on the inside face of flap 15, makes outer extension of teeth directional and exceeds the peripheral edge of flap.Yet if desired, blade 40 can be installed on the inside face of casket or on the outside face, and can be positioned at the optional position on the casket, for example lower edge of the front panel 5 of casket.

Fig. 2 provides other transparent view of the casket of Fig. 1 with 3 from different viewpoints, so that the solid geometry shape of box structure to be shown better.Fig. 4 also is the fragmentary, perspective view of the casket of Fig. 1 to 3, shows the inner member of lid/flap/top board, the installation of blade 40 and the closed block part (hole 55 on the plate 11) of casket, and this will be in following explanation.

In the use, when flap 15 remained on the front panel 5 overlapping closed positions with casket, the width of cloth sheet of sheet material 20 can draw and lean against on the blade 40, with from rolling up the sheet material that downcuts Len req.This layout has prevented that the afterbody of roll from dropping in the casket behind the material that downcuts Len req, because continuous sheet can be clipped between flap 15 and the front panel 5 by " afterbody " or the tip edge that cutting operation causes.The tip edge of Reference numeral 21 expression sheet materials, it generally includes " afterbody " that stays after the rupturing operation formerly.
