Description

The present invention relates to a wrap film case in which a necessary amount of a wrap film is drawn from a roll in which the wrap film is wound around a core, and is used after being cut.

In the conventional disposable wrap film case shown in FIG. 10 , a roll 54 wound around a winding core is housed in a paper case body 51. When using, the case lid 52 is opened about half, and the tip of the wrap film 55 is made visible, and then the wrap film 55 is picked and pulled out by a necessary length, and a cutting blade provided at the edge of the case lid 52 53 is pressed against the wrap film 55 while closing the case lid 52 and cut.

In the conventional wrap film case shown in FIG. 10 , since the saw blade-like cutting blade 53 is always exposed, there is a risk of damaging the fingertip with the cutting blade 53 during the cutting operation of the wrap film 55.

As shown in FIG. 10, after the cutting of the wrap film 55 can not be visually covered tip of that is the case lid 52.

Therefore, as shown in FIG. 11 , it is necessary to open the case lid 52 about half in order to see the tip of the wrap film 55. As a next operation, the wrap film 55 that can be visually observed is picked, but the wrap film is a thin film of micron unit, and is attached to the case body 51 by static electricity, affinity, etc., and the tip of the wrap film 55 is picked. Is not free.

As a solution to this, there is a wrap film case with a picking assisting process 56 that makes it easy to pick the tip of the wrap film 55, as shown in FIGS. Since it is a brace, it is not fully satisfactory.

12, in another type of wrap film case, cut wrap film 55 tip, made visually, there was easy knob work picking was improved. However, since the sawtooth-shaped cutting blade 61 is exposed at the corner of the case body 51 that is most likely to be injured, the danger increases.

In a conventional wrap film case, the end of the wrap film 55 may stick to the roll 54 and the operation may not be continued. When the tip of the wrap film 55 sticks to the roll 54, the tip is peeled off using the tip of a nail or a cello tape, but this returning operation is very complicated.

Cause of this is there two, as a 1, when opening the case lid 52, soar lifted the wrap film 55, a case where become stuck to the roll 54.

Cause 2 is a case where the roll 54 is idled in the case main body 51 to cause rewinding and the wrap film 55 is stuck to the roll 54.

Cause 1 solution thereof, as shown in FIGS. 10 and 11, provided the adhesive coating unit 57 to the case body 51, a method of pasting the wrap film 55 temporarily. However , since the wrap film 55 is affixed with an adhesive, the work of pulling out the wrap film 55 requires that the wrap film 55 be first rolled up and peeled off from the case body 51. .

Causes the second solution, as shown in FIGS. 10 and 12, to prevent the jumping out of unwinding and rolls 54 of the roll 54, it is a method of forming a core presser processing 58. However, since the remaining amount of the roll 54 is reduced because the cardboard is simply pushed and bent, and the roll diameter is reduced, the prevention function is not sufficient.

In conventional disposable wrap film cases, paper, metal, and plastics are disassembled and disposed of after the wrap film has been used up. Risk of injury.

Conventional wrap film cases are a waste of important forest resources because paper cases are disposable for each roll.

There is a refillable hard case described in Patent Document 2 and Japanese Patent Application Laid-Open No. 2005-88991. When the case lid is closed, the cutting blade is housed inside the lid so that there is no risk of injury and it is safe. However, when the case lid is opened, the cutting edge of the cutting blade with good sharpness is exposed and the fingertip is injured. The risk of injury is not prevented and safety cannot be said to have improved.

Since the hard case is a method of fixing the wrap film to the roll at the tip of the wrap film by rewinding the wrap film, an adhesive material is applied to the case body and the wrap film is temporarily attached. The case cover must be opened and the wrap film peeled off from the adhesive application part before the wrap film is pulled out, and the case cover must be closed again for cutting. Is not improved.

Generally speaking, the conventional disposable wrap film case has a risk of always injuring the fingertip with the exposed cutting blade, and it is an operation that takes care of the fingertip and is not reliable. The cutting operation is complicated by opening and closing the case lid each time. When strong force is applied, there is no stability. Lap film sticking to rolls, separation and disassembly work after use up, wasteful use of resources. The background of conventional wrap film cases is that it cannot be said that old and young men and women can use it with peace of mind.
