ABSTRACT:

TECHNICAL FIELD
This invention relates to a device for supplying wrap film, and more particularly, is applicable to cutting a wrap film for necessary amount from a container to use when wrapping, storing or cooking food etc., or the like.
BACKGROUND ART
Heretofore, as this kind of wrap films, for example, as shown in
FIG. 22
, a wrap film body
11
is contained in a box-type container
20
made of paper. When in using, a user opens a lid
22
, taking the almost center part A of a wrap film
11
a
with his/her fingers, drawing out a necessary amount, and then cutting it with a tooth-shaped cutting edge
24
fitted to a front sheet piece
23
that is bent downward at the front end of the lid
22
.
In the conventional wrap film container having such structure, there are problems as follows.
(1) If the user carelessly tries to draw out the wrap film
11
a
with taking only the right or the left edge with his/her fingers, it cannot be well drawn out because the wrap film
11
a
in the upper layer is adhering to the wrap film
11
a
in the lower layer owing to the compatibility of the same materials (meaning that the same materials mutually fit well and apt to adhere to each other) due to the material of the wrap film
11
itself. Even if it can be drawn out, only one edge side is drawn out and the wrap film
11
a
wrinkles, so that it cannot be drawn out well in balance over the width. Thus the user must take the almost center part A with his/her fingers with confirming by his/her eyes every time and draw it out; it is troublesome.
(2) When in unusing, the tip of the cutting edge
24
has been exposed outside. Thus there is the possibility of careless injury. More particularly, it is dangerous for babies who have the habits of putting anything in his/her mouse and making it plaything of him/her; it lacks with PL measures.
(3) Since the user draws out and uses the wrap film
11
a
with taking with his/her fingers, if the hand is dirty, there is the possibility that the wrap film
11
a
and the container
20
are contaminated with unwanted bacteria; in nowadays that O-157 measures are cried for, it is not very preferable from the point of view of hygiene.
DISCLOSURE OF INVENTION
This invention has been done considering the above points, and aims to provide a device for supplying wrap film in which a wrap film can be drawn out easily and well in balance so as not to wrinkle, and the device is superior in safety and hygienic.
To solve the above problems, according to this invention, a wrap film container
1
having a box part (
2
,
3
,
4
,
5
) having an opening
6
at the top and housing a wrap film body
11
formed by a rolled wrap film
11
a
, a sheetlike lid
7
fitted to the box part (
2
,
3
,
4
,
5
) so as to freely openably cover the opening
6
, and a cutting edge
10
fitted to the front end of the lid
7
or the front sheet
2
of the box part (
2
,
3
,
4
,
5
), and in a state where the end of the wrap film
11
a
is drawn outward from a space between the opening
6
and the lid
7
via in front of the front sheet
2
of the box part (
2
,
3
,
4
,
5
), by pressing the base of the end part against the cutting edge
10
, for cutting off the end part from the wrap film body
11
, and a sheetlike wrap film guide
13
in a state of peelably adhering to the end of the wrap film
11
a
in front of the front sheet
2
of the box part (
2
,
3
,
4
,
5
), to be pulled out in one body with the above end part almost over the whole width, and capable of cutting off the end part by pressing the base part against the cutting edge
10
, are provided.
Thereby, the wrap film
11
a
can be drawn out with the wrap film guide
13
easily and well in balance without forming wrinkles.
Furthermore, the end of the lid
7
is bent downward oppositely to the front sheet
2
of the box part (
2
,
3
,
4
,
5
), and the cutting edge
10
is provided at the end of the above bending part, and at the same time, a freely-turnable cover sheet
12
for protection is provided in front of the above cutting edge
10
.
Thereby, the cutting edge
10
can be protected so as not to be dangerous for a user.
The end of the lid
7
is bent downward oppositely to the front sheet
2
of the box part (
2
,
3
,
4
,
5
), and the cutting edge
10
is fitted to the end of the above bending part, and at the same time, a recessed part “a” for protection in which the cutting edge
10
can be inserted from below is formed on the top surface of the wrap film guide
13
, and when in unusing, the recessed part “a” of the wrap film guide
13
is inserted in the cutting edge
10
to prevent that the cutting edge
10
is exposed to the outside.
Thereby, the cutting edge
10
can be protected so as not to be dangerous for the user.
The cutting edge
10
is provided at the bottom end of the front sheet
2
of the box part (
2
,
3
,
4
,
5
), and at the same time, the front end of the lid
7
is bent downward oppositely to the front sheet
2
of the box part (
2
,
3
,
4
,
5
), and the bottom end is extended to the position in front of the cutting edge
10
and protecting the cutting edge
10
.
Thereby, the cutting edge
10
can be protected so as not to be dangerous for the user.
The wrap film container
1
is formed by a transparent or a semi-transparent material, or an window is formed in a part of it. Thereby, the remaining amount of the wrap film body
11
contained inside can be confirmed.
The wrap film container
1
and/or the wrap film guide
13
is subjected to antimicrobial treatment.
Thereby, the wrap film
11
a
can be cut off hygienically.
According to this invention as the above, a device for supplying wrap film has wrap film guides
13
,
13
A,
13
B,
13
C and
13
D capable of adhering to a wrap film
11
a
, to draw out the wrap film
11
a
with these wrap film guides
13
,
13
A,
13
B,
13
C and
13
D. Thereby, the device in which the drawing-out and cutting work of the wrap film
11
a
is easy and a user can cut off the wrap film
11
a
without directly touching it and the wrap film
11
a
is not contaminated can be obtained.
Since the wrap film container
1
is made transparent or semitransparent or an window is provided, the remaining amount of the wrap film body
11
contained inside can be known in advance.
Since when in unusing the edge part
10
a
of the cutting edge
10
is covered with the cover sheet
12
, or the cutting edge housing part “a” of the wrap film guide
13
and the recessed parts
13
a
and
13
b
of the wrap film guide
13
A and
13
B, injury of a user can be prevented and it is superior in safety.
Since the wrap film container
1
and the wrap film guides
13
,
13
A and
13
B are subjected to antimicrobial treatment, it is hygienic.
Moreover, by providing two pieces of wrap film guides, if the first wrap film guide
13
C is detached, the wrap film
11
a
automatically adheres to the surface of the second wrap film guide
13
D set. The first and the second wrap film guides
13
C and
13
D can be alternately used. Furthermore, even if one of them is lost or broken, the wrap film
11
a
can be used with the other remaining.
