Description




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.

BEST MODE FOR CARRYING OUT THE INVENTION




This invention will be described in detail with reference to the accompanying drawings.




(1) First Embodiment




Referring to

FIGS. 1

to


3


, a reference numeral


1


designates a box-type wrap film container. This wrap film container


1


is formed in a box shape having an opening part


6


at the top by a front sheet


2


, a bottom sheet


3


, left and right side sheets


4


and a back sheet


5


, and having a lid


7


of which the base end


7




a


is provided freely turnably to the back sheet


5


. At the both ends in the longitudinal direction of the lid


7


, side sheet pieces


8


which are located mutually oppositely on the outside of the side sheets


4


are provided respectively. At the front end of the lid


7


, a front sheet piece


9


which is perpendicularly bent downward is provided. The dimension of this front sheet piece


9


extending downward is about half of the dimension of the front sheet


2


.




The container having the above structure is formed for example by injection-molding synthetic resin. As the material of the synthetic resin, plastic such as epoxy resin, acrylic resin, etc. can be considered. Such molded products are more durable than conventional products made of paper. Therefore, when a wrap film


11




a


is used up, the container can be reused by refilling a new one. Here, adhering a piece of sheet into a box shape by using adhesive material or ultrasonic welding or the like is also possible, however, the molded products are more superior in labor and productivity.




A tooth-shaped cutting edge


10


is provided inside the front sheet piece


9


by integral molding. An edge part


10




a


at the end of this long and narrow beltlike cutting edge


10


is slightly exposed from the front end of the front sheet piece


9


, and it can cut the wrap film


11




a


drawn out.




As shown in

FIG. 4

, at the lower front end of the front sheet piece


9


, a cover sheet


12


which is freely turnable to the outside of the front sheet piece


9


and to cover the edge part


10




a


at the tip of the cutting edge that extends downward and the length dimension is short, is provided, to prevent that a user such as a little child or the like is not accidentally injured by the edge part


10




a


(to protect the edge part


10




a


).




The wrap film


11




a


has self-adhesion property that smooth surfaces adhere to each other. Accordingly, in the case where the surface of the wrap film container


1


is smooth as it adheres to the wrap film


11




a


and the material of the container is a material which is apt to adhere to the wrap film


11




a


, the wrap film


11




a


is hard to draw out. From this reason, it is preferable that such plastic is avoided as the material of the wrap film container


1


. In the case where the wrap film


11




a


is a material apt to adhere, to prevent adhering, the inner surface of the container may be unevenly finished to reduce a contacting state of the wrap film


11




a


to the surface of the container, and lower the degree of contact. Of course, even if the surface is smooth, if it is a material hard to adhere, it may be used. As the material hard to adhere, for example a sheetlike object coated by a cation surface-active agent or fluoroplastic, or a sheetlike object made of a synthetic plastic can be applied.




Moreover, a transparent or a semi-transparent material is used for the wrap film container


1


. Therefore, the remaining amount of the wrap film body


11


contained in it can be seen.




Means for making the lid


7


freely turnable to the back sheet


5


or making the cover sheet


12


freely turnable to the front sheet piece


9


can be easily accomplished as shown in

FIGS. 5 and 6

, by connecting, for example with a tape


33


having warpability, the mutual members, that is, in this case, the lid


7


and the back sheet


5


or the front sheet piece


9


and the cover sheet


12


, or as shown in

FIG. 7

, by forming, as a part to be a connecting part wanted to bend, a recessed part B on the rear side as a thin part “a” at the time of molding, because the resin having the warpability has flexibility. On the other hand, oppositely to

FIG. 7

, as shown in

FIG. 8

, if the recessed part B is formed on the surface, when the cover sheet


12


is bent to the front sheet piece


9


, a mutual comer part A can function as a stopper as the bending range.




Referring to

FIGS. 1

to


4


, a reference numeral


13


designates a wrap film guide. This wrap film guide


13


is formed in a sheet form having a thickness of almost 0.5 mm to 2 mm. When in unusing, it will be housed as pinched between the front sheet


2


and the front sheet piece


9


. In this case, the wrap film guide


13


is never bulky since it is thin. The drawn-out wrap film


11




a


adheres to for example the upper end of the inner surface or the outer surface of this wrap film guide


13


, and the upper end has been pinched between the front sheet


2


and the front sheet piece


9


. Thereby, the wrap film guide


13


can be held without slipping off.




Note that, in the state shown in FIG.


2


and others, there is a space between the front sheet


2


, the wrap film guide


13


and the front sheet piece


9


. However, this drawing shows each member to make clearly understandable. In actual products, each member will be contacted.




Furthermore, since the wrap film guide


13


is formed by the synthetic resin and the surface is a smooth plane, it has compatibility with the wrap film


11




a


that has the self-adhesion property caused by the material. Also owing to the function of static electricity, it can easily adhere only by bringing close or contacting. Since also the surfaces of the front sheet


2


and the front sheet piece


9


are smooth planes, the wrap film guide


13


can be held by sandwiching between the front sheet


2


and the front sheet piece


9


by their adhesive power; it never falls even if shaking.




As the material of the wrap film guide


13


, a material made of plastic such as acrylic resin, epoxy resin, etc. is used. Thus, the surface is smooth and it is apt to adhere to the wrap film


11




a


. More particularly, the acrylic resin is polyfunctional, the molecular amount is small, and at the time of heat-molding, the surface becomes a soft gloss-coated layer. Therefore, adhesive intensity to the wrap film


11




a


is good.




The wrap film body


11


has a circular section, is made of paper, and coiled around the outer circumference of a cylindrical core member


14


in a roll. This wrap film


11




a


is formed by a plastic film such as polyvinylidene chloride, polyvinyl chloride, polybutadiene, polyethylene, etc.




In case of this embodiment, antimicrobial treatment is subjected to the wrap film container


1


and the wrap film guide


13


.




As an antimicrobial agent, metals such as silver, copper, zinc, tin, etc. and an organic compound or an inorganic compound including it can be used. Considering the safety and the durability of effectiveness, silver-related or copper-related inorganic antimicrobial agent is preferable. Furthermore, it is good to mix an antimicrobial agent by silver ions or copper ions into the aforementioned resin in a respect of low price. Or also it may be applied to the surface of a molded product.




As other antimicrobial agents, garlic, Japanese horseradish (wasabi), and catechin of Japanese green tea that are vegetable may be pulverized and mixed. The antimicrobial agent made from wasabi is known that it has a fine effect also on O-157. If using this antimicrobial agent, an antimicrobial component in wasabi gradually evaporates, and an increase in colon bacillus or the like can be inhibited.




According to the above structure, in using, in the state shown in

FIGS. 1

to


3


, by taking the lower end part of the wrap film guide


13


with fingers and pulling forward, a necessary amount of the wrap film


11




a


can be drawn out easily and well in balance as shown in

FIG. 9

, since the wrap film


11




a


is adhering to the end part over the whole longitudinal direction by the self-adhesion property.




In this case, as shown in

FIG. 9

, if the wrap film guide


13


is drawn out in the horizontal direction to the wrap film


11




a


, at this time, coefficient of friction between the wrap film guide


13


and the wrap film


11




a


becomes maximum. Therefore, the state where the wrap film


11




a


is adhering to the surface of the wrap film guide


13


can be maintained. Then, as shown in

FIG. 10

, by bringing up the cover sheet


12


and making the edge part


10




a


to expose, and pressing the wrap film


11




a


against the cutting edge


10


, the wrap film


11




a


can be cut. In this manner, it never becomes obstructive at the time of cutting or never disturbs the cutting.




As shown in

FIG. 11

, by making the cut wrap film


11




a


adhere to the top surface on the outer circumference


15




a


at the upper opening part of a container


15


in that a food


16


or the like has been contained and turning the wrap film guide


13


for example as the lower part is a fulcrum as shown by an arrow, coefficient of friction gradually disappears and the cut wrap film


11




a


can be easily stripped off in a rapid motion without taking the wrap film


11




a


adhered to the inner surface with fingers.




Thereafter, the user makes the upper part of the wrap film guide


13


adhere to the end part of the wrap film


11




a


drawn out of he wrap film container


1


. At this time, since the wrap film


11




a


is adhering to the front sheet


2


, as shown in

FIG. 1

, the user may house the wrap film guide


13


between the front sheet


2


and the front sheet piece


9


. Adhesion can be easily performed only by getting close the wrap film guide


13


to the wrap film


11




a


owing to static electricity. Or by making them contact to each other, they can be adhered to each other owing to the self-adhesion property of the wrap film and the compatibility of the wrap film guide


13


.




According to the above structure, in the next use, the wrap film


11




a


can be drawn out again easily and well in balance from the wrap film container


1


by pulling forward the wrap film guide


13


again in the state where the wrap film


11




a


is adhering to the upper end of the wrap film guide


13


.




As shown in

FIGS. 1

to


3


, since when in unusing the edge part


10




a


is covered with the cover sheet


12


, it can be safely protected so that the user is never injured.




Furthermore, since the wrap film


11




a


is drawn out via the wrap film guide


13


, occasion to directly touch the wrap film


11




a


becomes fewer than a conventional case, and it is hygienic.




Moreover, since the material of the wrap film container


1


and the wrap film guide


13


is strong and durable, if the wrap film is used up, they can be reused any number of times by separately refilling a new wrap film body


11


; it is economy.




(2) Second Embodiment





FIGS. 12 and 13

show a second embodiment of this invention. This embodiment has characteristics that a part of a wrap film guide


13


is made thick and an almost-recessed cutting edge housing part “a” for housing a cutting edge


10


when the wrap film guide


13


is fitted to a wrap film container


1


is formed.




Therefore, even if a cover sheet


12


is not provided as the case of

FIGS. 1

to


4


, the cutting edge


10


is never exposed to the outside. Thus the cutting edge


10


can be protected so that the user is never injured.




(3) Third Embodiment





FIG. 14

shows a third embodiment of this invention. This case has characteristics in a point that the front surface of a wrap film container


1


can be covered with a wrap film guide


13


A and a cutting edge


10


is provided at the front end part


3




a


of a bottom sheet


3


.




Here,

FIG. 14

shows the mutual relationship of members so that there are spaces on the both sides of a wrap film


11




a


, however, this is only to intelligibly show in the drawing. Practically, the wrap film


11




a


will be adhered to the inner surface of the wrap film guide


13


A by the self-adhesion property of the wrap film


11




a


, and the wrap film


11




a


will be also adhered to the outside of a front sheet


2


provided in standing at the front end of the top surface of the bottom sheet


3


by the self-adhesion property. Thus it is light, and the wrap film guide


13


A in a thin sheet form can be held in front of the wrap film container


1


.




On the other hand, a recessed part


13




a


in a notch form is formed at the lower inside of the wrap film guide


13


A. The edge part


10




a


of the cutting edge


10


will be housed in this part, so that when in unusing the edge part


10




a


is protected so as not to be exposed to the outside.




According to the structure of

FIG. 14

, when in unusing, the wrap film guide


13


A is adhered to the wrap film


11




a


drawn out in front of the front sheet


2


by adhesive power caused between them. At this time, the cutting edge


10


is housed in the recessed part


13




a


provided at the lower inside of the wrap film guide


13


A, and is protected to prevent from injuring the user.




In this state, if the user takes the wrap film guide


13


A with his/her fingers and pulls forward, the end of the wrap film


11




a


adhering to the wrap film guide


13


is pulled forward, so that the wrap film


11




a


is drawn out of the wrap film container


1


. Thereafter, if the user moves the wrap film guide


13


A under the bottom sheet


3


, the wrap film


11




a


is pressed against the cutting edge


10


and cut.




At this time, since the wrap film


11




a


drawn out is remaining in front of the front sheet


2


, if the user detaches the cut wrap and adhering the wrap film guide


13


A, it returns to the aforementioned unusing state.




Thereby, the same effect as the case described above with reference to

FIGS. 1

to


4


can be obtained.




(4) Fourth Embodiment





FIG. 15

shows a fourth embodiment of this invention. In this case, a front sheet piece


9


which extends downward is provided at the front of a lid


7


. The lower end of this front sheet piece


9


extends to the almost half of the height of a front sheet


2


. Even if a wrap film guide


13


B is detached, there is the front sheet piece


9


in front of a space formed between the upper end of the front sheet


2


and the inner surface of the lid


7


opposite to this to draw out a wrap film


11




a.






According to the above structure, the user can perform the cutting work of the wrap film


11




a


in the same manner described above with reference to FIG.


14


. Therefore, dust can be hard to enter the inside of a wrap film container


1


owing to the front sheet piece


9


and the front sheet


2


. On the other hand, the upper end of a wrap film guide


13


B can be held freely detachably further readily.




(5) Fifth Embodiment





FIGS. 16

to


21


show a fifth embodiment of this invention. In this case, two pieces of wrap film guides


13


C and


13


D are overlapped each other and used in a wrap film container


1


.




In this case, as shown in

FIGS. 16 and 17

, two bars of ribs


17


(formed by a synthetic resin material) which extend in the vertical direction are respectively provided at the both side parts of a front sheet


2


. A hook part


18


having a taper part


18




a


that can be engaged with the first and the second wrap film guides


13


C and


13


D are projectively provided in a triangular toward the inside for example at the upper insides of the respective ribs


17


. On the reverse side (i.e. the outside) of the hook parts


18


, notch parts “b” are formed, so that the hook parts


18


can be warped to the outside.




At the both ends of the respective first and second wrap film guides


13


C and


13


D, notches


19


each of which has a taper part


19




a


that can be engaged with the hook part


18


are formed so as to be recessed in a triangular shape toward the inside almost correspondingly to the hook parts


18


. Thereby, the first and the second wrap film guides


13


C and


13


D can be held at the front of the wrap film container


1


.




When the two pieces of wrap film guides


13


C and


13


D are overlapped each other, the first wrap film guide


13


C or


13


D located in the outside (in case of

FIG. 8

, it is


13


C) is adhered to the front of the wrap film


11




a.






According to the above structure, when in using, referring to

FIGS. 16 and 17

, a user first takes the first wrap film guide


13


C located in the outside, and moving it forward so that the notches


19


are released from the hook parts


18


. Then, as shown in

FIG. 19

, the user draws out a predetermined amount of the wrap film


11




a


from the wrap film container


1


, pressing the base end of the above drawn-out wrap film


11




a


against a cutting edge


10




a


, and cutting the end part of the wrap film


11




a.






In this state, as shown in

FIGS. 19 and 20

, the front surface of the second wrap film guide


13


D that was on the inner side is pulled out from the wrap film container


1


and adhered to the wrap film


11




a


remaining without cutting.




Thereafter, as shown in

FIG. 20

, the first wrap film guide


13


C will be pushed into a space between the front sheet


2


and the second wrap film guide


13


D by the user as shown by an arrow. In this case, since the notches “b” have been formed on the reverse side of the hook parts


18


of the ribs


17


, as shown by an arrow in

FIG. 17

, the hook parts


18


warp to the outside, so that the wrap film guide


13


C can be easily pushed into. Thus the notches


19


can be engaged with the hook parts


18


at the inside of the second wrap film guide


13


D together with this.




At this time, the two pieces of film guides


13


C and


13


D overlapped each other can be set in the same manner as

FIGS. 16 and 18

except for that the positional relationship of the first and the second wrap film guides


13


C and


13


D has been opposite.




When the wrap film is used next time, the second wrap film guide


13


D located in the outside is moved forward from the wrap film container (


1


), and the same procedure is repeated hereafter.




According to the structure in

FIGS. 16

to


20


, since the user alternately uses the two pieces of wrap film guides


13


C and


13


D, the drawing-out and cutting work of the wrap film


11




a


can be further easily and surely performed.




(6) Sixth Embodiment




In the aforementioned embodiments, as the wrap film guide


13


, the synthetic resin which is a material apt to adhere to the wrap film


11




a


has used to obtain the adhesive power for making the wrap film guide


13


adhere to the wrap film


11




a


. However, instead of or additionally to this, a temporal stopper member having an adhesive power to the wrap film


11




a


may be provided on the surface of the wrap film guide


13


.




Specifically, to a wrap film guide


13


formed by a material of which the property of adhering to the wrap film


11




a


is large or a wrap film guide


13


formed by a material of which the property of adhering to the wrap film


11




a


is small, if for example bridging hardening varnish is partially applied and an applied layer in a flat thin film (not shown) is provided on the whole surface or in a suitable part of the wrap film guide


13


, the adhesive power to the wrap film


11




a


is improved. That is, since this applied layer is solid and smooth varnished layer, the adhesive property to the wrap film


11




a


is improved.




As this kind of varnish, for example a material in which acrylic denatured resin such as epoxy-related acrylate, polyester-related acrylate, etc. is base range, or unsaturated polyester resin (UP) may be used.




Instead of the varnished layer, even if a sticking layer made of a composition of resin containing chloroethene group is provided, adhering and peeling-off can be repeated and the same effect can be obtained. However, it is desirable to avoid a thing related to chlorine as you can from dioxin measures.




This is formed by providing an adhesive elastomer on a filmlike seal material. This member can reuse any number of times because it is freshened by washing by water when dusts are stuck on the surface and the adhesive power is lowered.




If using the temporary stopper member as above, as the material of the wrap film guide


13


to which the wrap film


11




a


is hard to adhere, also cardboard as a conventional case, synthetic plastic, a thin plate made of for example, magnesium metal, ceramic, etc. can be used.




(7) Other Embodiments




(i) Referring to

FIGS. 1

to


3


, the side sheet pieces


8


of the lid


7


may be omitted provided that the airtightness of the wrap film container


1


when the lid


7


is closed, and the intensity of the lid


7


and the front sheet piece


9


are high.




(ii) In the aforementioned embodiments, the cutting edge


10


has molded in one body with the wrap film container


1


. However, instead of this, a cutting edge made of a thin metal plate may be fitted to a wrap film container


1


by a bonding agent or a fixing member.




(iii) In the aforementioned embodiments, as the wrap film container


1


, the material being transparent or semi-transparent resin has wholly used, so that the remaining amount of the contained wrap film body


11


can be confirmed. However, instead of this, provided that the remaining amount of the contained wrap film body


11


can be confirmed, it may be partial, for example, the side sheet


4


may be provided at only one side. Besides, for example an window (not shown) may be formed on the side sheet


4


, the lid


7


, etc., to see the inside, and the other part may be opaque and made a display part to mention an explanation of the product or the like. In this case, as a material in this case, for example colored plastic can be considered.




Besides, instead of this, as the material of the wrap film container


1


, cardboard, a thin plate of synthetic plastic, magnesium alloy, a ceramic thin plate may be used.




(iv) In the aforementioned embodiments, in the case where also the members other than the wrap film guide


13


have the adhesion property to the wrap film


11




a


, in the same manner as the aforementioned sixth embodiment, a temporal stopper member may be provided on the wrap film guide


13


to determine the adhesive power as the entire wrap film guide


13


including the adhesive power of this temporary stopper member.




For instance, when the wrap film


11




a


drawn out of the wrap film body


11


in the wrap film container


1


by means of the wrap film guide


13


is cut with the cutting edge


10


, there is the possibility that the end part of the wrap film


11




a


once drawn out is pulled back into the wrap film container


1


when the wrap film body


11


falls in the wrap film container


1


(because it loses the drawing power by cutting) from the state where the wrap film body


11


has been drawn to the opening for drawing out as a whole.




To prevent this, it can be considered that a draw-back stopper member having adhesive power to the wrap film


11




a


is provided near the opening for drawing out the wrap film


11




a


(for example at the top end of the front sheet


2


and/or on the inside of the front sheet piece


9


).




In such case, even if the user tries to draw out the wrap film


11




a


by taking out the wrap film guide


13


from the wrap film container


1


, the wrap film


11




a


adheres to the draw-back stopper members of the front sheet


2


and the front sheet piece


9


. Thus the wrap film


11




a


cannot be smoothly drawn out.




In this case, mutual adhesive power may be controlled by reducing the area of the draw-back stopper member provided on the front sheet


2


or the front sheet piece


9


to weaken the adhesive power to the wrap film


11




a


, and by increasing the area of the temporary stopper member on the wrap film guide


13


to increase the adhesive power.




Moreover, for example in the case where the same material is selected for the wrap film guide


13


, the front sheet piece


9


and the front sheet


2


, for instance, a part of or the whole inner surfaces of the front sheet


2


and the front sheet piece


9


may be unevenly formed to make the contacting area to the wrap film


11




a


smaller than the wrap film guide


13


.




(v) In case of

FIGS. 14 and 15

, when in unusing, the wrap film guide


13


A is held by the wrap film container


1


owing to the adhesive power to the wrap film


11




a


drawn out in front of the front sheet


2


. However, to increase the holding power to the wrap film


11




a


, a holding temporal stopper member may be provided on the surface of the wrap film guide


13


A.




On the other hand, a holding power for holding the wrap film guide


13


A may be provided in the bottom sheet


3


. As the holding part, for example it can make the structure that the wrap film guide


13


A will be fitted into the end of the inner surface of the lid


7


.




(vi) In case of

FIGS. 14 and 15

, the edge part


10




a


has provided at the front end of the wrap film container


1


(more particularly, the under surface of the bottom sheet


3


). However, instead of this, the main body part may be embedded in the bottom sheet


3


, and the edge part


10




a


may be projected to the outside. Or the edge part


10




a


may be put between the top surface of the bottom sheet


3


and the under surface of the front sheet


2


.




(vii) Similarly to the case of

FIG. 20

, in the case where the two pieces of wrap film guides


13


C and


13


D are used with overlapping, as shown in

FIG. 21

, if the corners of the tip part of the wrap film guides


13


C and


13


D have been previously formed in a shape as chamfered, when the first wrap film guide


13


C after using (or the second wrap film guide


13


D) is pushed into, the respective taper parts “It” at the top end and the bottom end of the wrap film guides


13


C and


13


D can be mutually inserted. Therefore, the insertion of the wrap film guide


13


C (or


13


D) into the wrap film guide


13


D (or


13


C) from the outside can be further easily performed.
