Abstract
The invention discloses a preservation film reel with core reel flanges, belongs to the technical field of daily necessities and provides a large-volume preservation film reel suitable for a non-paper box device. The preservation film reel comprises a core reel and a preservation film. The core reel is in a long strip circle shape. The two ends of the core reel are each provided with a reel opening. The diameter of each reel opening is matched with the outer diameter of a rotating point of a preservation film using device. The two ends of the core reel are each provided with one core reel flange. The preservation film is reeled on the outer diameter of the portion, between the two core reel flanges, of the core reel. The width of the preservation film is not larger than the length between the two core reel flanges. The preservation film reel has the advantages that materials are saved due to the fact that core reel is smaller, the preservation film reel can be more easily limited on the rotating point of the using device through the core reel with the smaller reel openings, the reel openings are in close fit with the rotating point of the preservation film using device, the non-paper reel can easily achieve matching precision, the preservation film reel can flexibly rotate inside the using device without free swing, and the preservation film is prevented from making contact with an inner wall and being polluted.
Description
Technical field
The invention belongs to article of everyday use technical field is and in particular to a kind of preservative film winding drum of core cylinder flange.
Technical background
Preservative film applies ratio wide in daily life, it is mainly used in the cleaning of food and fresh-keeping, the common usage of preservative film is preservative film to be rolled into tubular be placed in carton now, from carton, preservative film is pulled out when use, again preservative film is placed on the tooth bar on carton and breaks by force, or cut off with shears, cut off use with knife.
Because preservative film needs to be pulled apart on the serrated knife on carton, the number of times pulled apart that carton can bear is limited, the length of preservative film can not be oversize, because the big number of times using of length can increase, carton can not bear too many access times, so the length general control of existing preservative film is between 15 meters to 30 meters.
The thickness of preservative film is fairly small, even it is also diameter very little that 30 meters of freshness-retaining film roll gets up, if carton is according to rolled-up preservative film size design carton, not only carton is not because too tiny have intensity can not use, and can affect the desire bought.So the diameter of the carton of present preservative film is substantially to be felt as foundation with common staff, the width of section and height control in 5 cm, by 15 meters to 30 meters of freshness-retaining film roll on one of diameter 4 cm greatly refill, this preservative film winding drum spooled is put in carton, both met the requirement of access times, seem full air again；Simultaneously in order to prevent core cylinder from moving in carton, respectively can rout up in one piece of two ends that the scraps of paper are inserted in refill at the two ends of carton.
Above-mentioned using method is the caving-in bash of carton limitation in fact, because seeming full by spooling later preservative film winding drum, just puts greatly by the diameter of core cylinder, same using effect, the big core cylinder resources more many than the waste of little core cylinder；Because the access times limitation of carton, the length of preservative film can only be confined to 30 meters about, if 100 meters of preservative films rolled up by a core cylinder, actual effect is that this core cylinder instead of 3 to 5 big core cylinders, can save many resources.
A kind of design of plastic sheeting use device is disclosed, this design not only solves the problem of the potential safety hazard of the exposed tooth bar outside packaging of carton package, and in-convenience in use problem in Chinese patent ZL201010257081.5 before the present inventor；More primarily to solve carton be unable to undergo multiple turn from side to side can not reusable problem, and unhygienic problem.
The product of this design makees structure using the material of non-papery, being capable of multiple Reusability, the profile diameter of the profile of this use device is because the restriction of hand size can not be too big, so the section size of device inwall can be more limited, the preservative film how this limited inner wall space accommodates long length is the problem that needs solve；
Simultaneously, in order to prevent preservative film winding drum from polluting because contacting with device inwall, must be prevented from the swing in deviation center of circle when preservative film winding drum rotates, the two ends of preservative film winding drum need the run-on point close fit with use device, enable preservative film winding drum to think that in use device, flexible rotating is not the swing deviateing；
Existing preservative film winding drum can not meet above-mentioned requirements.
Content of the invention
The purpose of the present invention：The preservative film winding drum that a kind of suitable non-paper box device of Large Copacity preservative film uses is provided.
The present invention adopts following concrete technical schemes to realize the purpose of invention：A kind of preservative film winding drum of core cylinder flange, including core cylinder and preservative film, wherein：
Described core tube length strip is circular, and respectively there is a nozzle at two ends, respectively has a core cylinder flange at the two ends of core cylinder, and nozzle is rounded hollow, and nozzle diameter is matched with the external diameter of the run-on point of preservative film use device；
Above the core cylinder external diameter between two core cylinder flange, the width of preservative film is not more than the length between two core cylinder flange to freshness-retaining film roll.
Wherein：Within 2 millimeters of the external diameter of the run-on point with diameter greater than preservative film use device for the nozzle.
Wherein：The size of nozzle diameter is not more than 2 centimetres.
Wherein：The size of core cylinder external diameter is not more than 3 centimetres.
Wherein：The external diameter of preservative film winding drum is not more than 4 centimetres.
Wherein：The external diameter of core cylinder flange is less than 4 centimetres.
It is an advantage of the invention that：Little core cylinder is than big core shell ring material saving, little core cylinder can meet the preservative film of long length, the preservative film of long length is equivalent to the capacity of 5 20 meters of preservative film winding drums, directly saves 4 core cylinders than the preservative film save resources of little length, such as 1 100 meters of preservative film winding drum.
The core cylinder of little nozzle is easier to make preservative film winding drum be limited in the run-on point of use device, nozzle is fitted close with the run-on point of preservative film use device, preservative film winding drum can be enable in the inside flexible rotating of use device, will not freely swing, prevent the contact internal walls of preservative film and container, it is to avoid preservative film is polluted with contact internal walls.
The core cylinder of flange can make preservative film relatively easily roll up on core cylinder, even if producing some deviations also do not interfere with use.
The run-on point that the preservative film core cylinder of non-papery is easier to realize with preservative film use device closely coordinates.
