  As shown in FIG. 1, the wrap film storage case 10 has a basic structure in which a lid 12 that can be opened and closed is hinged to a rigid case body 11.

  The case main body 11 has a horizontally long box shape as a whole, and is formed into a box shape from the front plate 13, the bottom plate 14, the back plate 15 and the side plates 16 on both sides, and is wrapped with a wrap film in the storage chamber 17 inside thereof. The circular body R is accommodated. The height of the back plate 15 is set to be lower than the height of the front plate 13, and the upper end surfaces of the side plates 16 are formed as curved surfaces that are curved while being inclined downward from the front end to the rear end. The box-shaped case body 11 is made of lightweight plastic.

  A lid plate 12 is attached to the upper end of the back plate 15 through a hinge portion 17 so as to be opened and closed. The lid plate 12 is formed as a curved plate that curves while being inclined downward from the front end to the rear end in accordance with the curved upper end surfaces of the side plates 16. At the front end of the cover plate 12, a lid cover piece 18 extending downward along the front surface of the front plate 13 is provided. The lid cover piece 18 is provided with a pressing projection 18a projecting downward at the center of the tip, and an inclined portion 18b extends slightly upward and leftward from the pressing projection 18a at the center of the tip. A terminal end 18c extends upward from the both sides of the cover plate 12 with a slight gap d (d = 2 to 3 mm) and connected to the front end of the cover plate 12.

  On both sides of the lid plate 12, lid side plates 19 are provided. A locking recess 20 a is provided near the front end of the inner surface of the lid side plate 19, and a locking projection 20 b is provided near the front upper end of the outer surface of the opposing side plate 16. Thus, when the lid plate 12 is closed, the latch recess 20a on the lid side plate 19 side is elastically latched to the latch projection 20b on the side plate 16 side, and the closed state of the lid plate 12 is maintained. It has become. The locking recess 20a and the locking projection 20b constitute a first locking portion.

Along the tip of the lid piece 18, that is, from the tip of the pressing projection 18a to the left and right inclined portions 18b, and from the left and right inclined portions 18b to the terminal portion 18c, it was drawn from the wrap film roll R in the storage chamber 17. A cutting blade portion 21 for cutting the film F is attached. 2A and 2B, the cutting blade 21A of the cutting blade portion 21 has an acute angle with respect to the inner surface of the lid cover piece 18 from the front end of the pressing projection 18a to the left and right inclined portions 18b. At an angle α ₁ = 40 ° to 85 ° formed by the inner surface of the lid piece 18 and the cutting blade 21A, and as shown in FIGS. 3A and 3B, It is attached to the inner surface of the lid piece 18 at an obtuse angle (angle α = 95 degrees to 175 degrees between the inner surface of the lid piece 18 and the cutting blade 21A).

  The pressing protrusion 18 a of the lid cover piece 18 is provided with a pressing portion 22 that is pressed with a thumb when the film F drawn from the storage chamber 17 is cut. 22a (refer FIG. 5) is provided, and the latching recessed part 22b latched to the latching convex part 22a is provided in the outer surface of the front plate 13 which opposes. Thus, as shown in FIG. 4, when the film F drawn out from the storage chamber 17 is cut, the pressing portion 22 is pressed with the thumb, so that the locking convex portion 22a on the back surface is the film as shown in FIG. A part of F can be locked in the locking recess 22b and fixed so as not to move in the vicinity of the cutting line of the film F when the film F is cut. In addition, the latching convex part 22a and the latching recessed part 22b comprise a 2nd latching | locking part.

  The lid plate 17, the lid lid piece 18, the lid side plate 19, and the cutting blade portion 21 having the above-described configuration are all made of a lightweight plastic, like the case body 11.

  Next, an example of how to use the wrap film storage case 10 configured as described above will be described below.

  In order to store the wrapped wrap film R in the case body 11, the cover plate 12 of the case body 11 is opened by rotating around the hinge portion 17, and the wrap film wound body R is set in the storage chamber 17. When not in use, simultaneously with closing the lid plate 12, the first latching portion, that is, the latching convex portion 20b on the outer surface of the side plate 16 opposed to the latching concave portion 20a on the inner surfaces of both lid side plates 19 is elastically latched. The lid plate 12 is kept closed.

  In order to pull out the film F from the inside of the case body 11, as shown in FIG. 1, the cover plate 12 is rotated around the hinge portion 17 to open the cover plate 12. When the lid plate 12 is opened, the latching recesses 20a on the inner surfaces of both lid side plates 19 are easily released from the latching state with the latching projections 20b on the outer surface of the side plate 16 due to elastic deformation. In such a state, the case main body 11 is grasped with one hand (for example, the left hand), the amount of film F used is pulled out with the other hand (for example, the right hand), and the lid 12 is rotated around the hinge portion 17 again to remove the lid plate 12. close. Since the cover plate 17 is curved downward in an R shape from the front end to the rear end, the wrapping film roll R stored in the storage chamber 17 can smoothly rotate and the film F can be drawn out smoothly.

  Next, in order to cut the drawn film F with the cutting blade portion 21 at the tip of the lid piece 18, as shown in FIG. 4, the pressing protrusion 18 a of the lid piece 18 with the thumb of the hand holding the case body 11. The pressing part 22 is pressed. If it does so, as shown in FIG. 5, the latching convex part 22a of a back surface will latch the middle of the film F in the latching recessed part 22b, and will fix so that the cutting line vicinity of the film F may not move. In such a fixed state, tension is applied to the film F with the hand holding the end of the drawn film F, and the cutting edge of the cutting blade 21A of the cutting blade portion 21 is cut into the film F from the left and right ends. .

  In this case, for example, when “lifting up” is performed, the end of the film F that is held by hand is lifted, and one end (one end portion 18 c) of the cutting blade portion 21 is directed toward the other end (the other end portion 18 c). Tension is applied to the film F in the direction in which the film sequentially contacts, and the film is sequentially cut by the cutting blade 21A. Since the cutting blade 21A located at the terminal end 18c along the front end of the lid piece 18 is attached at an obtuse angle to the inner surface of the lid piece 18, the cutting edge of the cutting blade 21A is easily cut into the end of the film F and cut. Can start.

  Since the cutting blades 21A located at both end portions 18c along the front end of the lid piece 18 are attached at an obtuse angle with respect to the inner surface of the lid piece 18, the film F is held on the left hand and the film F on the left hand. In any case of gripping the edge, the cutting edge of the cutting blade 21A can be easily cut into the edge of the film F and cut.

  Further, the pressing part 22 of the pressing protrusion 18a of the lid piece 18 is pressed with the thumb of the hand holding the case body 11 and fixed so as not to move in the vicinity of the cutting line of the film F. It is possible to reliably apply tension to the film F and cut the film F with the cutting edge of the cutting blade 21A of the cutting blade 21 across the entire transverse direction.

  In the case of “horizontal opening”, the film F is spread by shaking the wrist holding the case body 11 horizontally and horizontally while maintaining the horizontal relationship between the case body 11 and the drawn film F. A tension may be applied to the cutting blade portion 21 so as to sequentially cut from one end (one end portion 18c) to the other end (the other end portion 18c).

  After the film F is cut, as shown in FIG. 6, a protruding portion a protruding forward from the left and right ends is formed at the center of the cut end of the film F. It is easy to pull the protrusion a with the finger of the other hand.

According to the wrap film storage case 10 of the present embodiment, the following effects can be obtained.
(1) The film F can be easily and reliably cut with a light force from either the left or right end in either case of lifting up or horizontally opening the film F by pulling it out from the case body 11.
(2) Since the cutting blade 21A of the cutting blade portion 21 is attached to the inner surface of the lid cover piece 18 at an acute angle from the front end of the pressing protrusion 18a of the lid cover piece 18 to the left and right inclined portions 18b, the film F is cut. There is little risk of the cutting blade 21A coming into contact with a finger or the like during or when not in use. Further, although the end portion 18c is attached at an obtuse angle with respect to the inner surface of the lid lid piece 18, a slight gap d is left from both ends of the front plate 13, so the cutting blade 21A is also a finger or the like at the end portion 18c. There is little risk of touching. Therefore, the film F can be cut while ensuring safety.
(3) Since the cover plate 17 is curved downwardly in an R shape from the front end to the rear end, the wrapping film roll R stored in the storage chamber 17 can be smoothly rotated and the film F can be pulled out smoothly. it can.
(4) Since the case main body 11, the cover plate 12, the cutting blade portion 21 and the like are made of plastic, the durability of the storage case 10 is maintained even when the hand gets wet in the kitchen work, unlike paper. Can do. Therefore, the stored wrap film can be used up comfortably to the end.
(5) Since the durability of the storage case 10 can be maintained, it is only necessary to replace the wrap film, which can contribute to the reduction of waste, and to the global environment by reducing CO ₂ emissions due to the reduction of combustible waste. Can contribute.
(6) Since the storage case 10 can be made into a firm structure, the wrapping amount of the film F can be increased by thinning the winding core of the wrapping film roll R.

  Thus, according to the wrapping film storage case of the present invention, it is easy to cut from the left and right ends with a light force, to realize a wrapping film storage case that is excellent in convenience and durability and is friendly to the global environment. Can do.

  In the above embodiment, a plastic material is used as the material of the storage case, but a light metal material such as aluminum may be used.

  The wrap film storage case according to the present invention can be widely used as a wrap film storage case in which a wrap film for food packaging, an alum foil, and the like are stored in a wound state.
