Description

  The present invention is intended to store food and drink or vegetables, fruits, etc. in a refrigerator or the like, or roll form wrapping used to suppress odor emission and maintain freshness and cleanliness when transporting (Wrapping) More specifically, a case in which a material is packaged can be used to cut the wrapping material accurately and conveniently without using a separate cutter by dramatically improving the material and configuration of the case. The present invention relates to a case having a function of cutting a wrapping material.

Generally, as a wrapping material used for packaging of foods (food or drinks, vegetables, fruits, etc.), synthetic resin wrap films, aluminum foil, kitchen paper sheets, and the like are known.

Such a wrapping material is manufactured in a thin sheet form and then wound and sold in a case made of a paper material in a roll form, but the user is wound in a roll form. The wrapping material (hereinafter referred to as “sheet”) is pulled out by a necessary amount, and then cut and used.

The normal case currently in use is made of paper and has a rectangular parallelepiped structure that can be opened and closed. A metal cutter with a serrated cutting blade is fixed on one side. Therefore, the user cuts the sheet by opening the lid, pulling the sheet by a necessary length, pulling the sheet, bringing it into contact with the cutting blade of the cutter, and pulling the sheet downward.

However, in such a case, the sheet is cut with a metal cutting blade, so that the user may inadvertently injure the hand frequently. Of course, the sheet is detached from the case in the process of cutting the sheet. The problem was that the sheet was not cut in a straight line because the sheet moved within the case when it was cut.

Therefore, in order to improve the above-mentioned problem, a new type of case has been published in Japanese Patent Publication (Japanese Patent Laid-Open No. 2003-175488).

FIGS. 1a and 1b are perspective views showing a conventional example, and FIG. 2 is a development view of a conventional storage and take-out container with a saw blade, which is connected to the container main body A and the same. A lid B that covers the upper surface opening of the container main body A is composed of a blank P such as cardboard or paperboard.

As shown in the developed view of FIG. 2, the blank P is provided with a front surface portion A1, a bottom surface portion A2, a rear surface portion A3, and left and right side surface portions A4 constituting a container body A through a broken line, and a lid B The upper lid portion B1, the front lid portion B2, and the left and right side lid portions B3 are connected via a broken line.

A cutting piece B4 is continuously provided at the front end of the front lid B2 with a sawtooth cutting line 1 interposed therebetween, and the sawtooth cutting line 1 is punched together with a nick 3 described later when the blank P is cut. The

Further, a plurality of teeth 3 larger than each angle blade 2a of the saw blade 2 are provided in the middle of the sawtooth cutting line 1, and blanks are formed by nicks 3a formed at the tips of the teeth 3. P is connected so as to be bendable, and the nicks 3a of the teeth 3 are projected from one of the facing cutting surfaces 1a and 1b of the sawtooth cutting line 1 toward the other.

In the illustrated example, the shape of the teeth 3 is shown as a chevron larger than each chevron of the saw blade 2, but is not limited thereto, and other shapes such as a substantially semicircle can be applied.

Then, in the manufacturing process of the storage and take-out container with a saw blade, the blank P is folded over the cut surfaces 1a and 1b of the saw-tooth cutting line 1 and the nicks 3a of the teeth 3 to make a saw-tooth cutting. Both the cut surfaces 1a and 1b of the wire 1 are exposed in a stepwise manner, and the curable resin R is applied to the exposed portion and cured while the two cut surfaces 1a and 1b of the sawtooth-shaped cutting wire 1 are exposed.

In the case of the present embodiment, as shown in FIGS. 1a and 1b, the front lid portion B2 of the lid B and the cut piece B4 are folded, and the cut surface 1a of the sawtooth cutting line 1 on the cut piece B4 side In addition, the cutting surface 1b of the serrated cutting line 1 on the cover B side is exposed, and both the exposed cutting surfaces 1a and 1b and the front and back surfaces of the blank P continuous to the exposed cutting surfaces 1b are coated with, for example, a roller or a brush. The curable resin R is applied in a strip shape with R1.

Explaining this in detail, the nicks 3a of the teeth 3 project from the cutting surface 1a of the sawtooth cutting line 1 on the cut piece B4 side toward the cutting surface 1b of the sawtooth cutting line 1 on the lid B side. A lid on which the saw blade 2 is formed from the cut surface 1a of the sawtooth cutting line 1 on the cut piece B4 side in a state where the cut piece B4 and the front lid portion B2 of the lid body B are folded over at the boundary. The cut surface 1b of the serrated cutting line 1 on the side of the body B is protruded in a stepwise manner.

In addition, the curable resin R may be an ultraviolet curable resin such as an acrylic polyester copolymer, an acrylic epoxy copolymer, or an acrylic urethane copolymer, or the same type of electron beam (EB) in order to shorten the curing time. ) It is preferable to use a curable resin.

In this case, the applied curable resin is cured by irradiation with ultraviolet rays or an electron beam.

Next, the operation of such a storage / takeout container with a saw blade will be described.

First, as shown in FIG. 1a and FIG. 1b, the front lid part B2 and the cut piece B4 of the lid B are bordered by the cut surfaces 1a and 1b of the sawtooth cutting line 1 and the nicks 3a of the teeth 3. Folded.

Thereby, the cutting surface 1a of the sawtooth cutting line 1 on the cut piece B4 side and the cutting surface 1b of the sawtooth cutting line 1 on the lid B side are exposed.

And when curable resin R is apply | coated to the both cut surfaces 1a and 1b of the exposed sawtooth-shaped cutting line 1 and the front and back both surfaces of the blank P continuous by it by the application | coating means R1, curable resin R is serrated. The entire cut surfaces 1a and 1b of the cutting line 1 are penetrated.

As a result, the tip surface of the saw blade 2 is reliably cured even with a simple resin coating method.

Furthermore, in a state where the cutting surface 1b of the sawtooth cutting line 1 on the lid B side on which the saw blade 2 is formed protrudes in a stepped manner rather than the cutting surface 1a of the sawtooth cutting line 1 on the cut piece B4 side, A curable resin R is applied.

Thereby, since the curable resin R is sufficiently permeated into the cutting surface 1b on the saw blade 2 side and the front and back surfaces of the blank P continuous thereto, the entire tip of the saw blade 2 can be reliably cured. .

Japanese Published Patent Publication No. 2003-174588 (2003.6.24, published) Japanese Published Patent Publication No. 09-012036 (1997.01.14. Published) Korea Public Utility Model Publication 20-2011-000744 (2011.01.24. Published) Korean Utility Model Registration Gazette 20-0213804 (2000.12.05. Registration)

However, in the conventional case having such a structure, the blank is folded over at the boundary between the sawtooth cutting line and the tooth nick, and both cut surfaces of the sawtooth cutting line are exposed in a stepwise manner. The application of a curable resin to the exposed portion has the advantage that the tip surface of the saw blade can be reliably cured, but the following various problems have occurred.

First, both cut surfaces of the sawtooth cutting line are coated with a curable resin on a blank made of paper material, but there is a limit to maintaining firm strength, so the sheet is cut in a straight line I can't do that.

Second, if the blank is inadvertently deformed during distribution or storage, the function as a cutter is lost, and the sheet cannot be cut.

Third, since the cutter is formed by applying a curable resin to the paper surface, a relatively thin sheet such as a wrap or foil can be cut, but a paper sheet cannot be cut.

Fourth, since the cutter is formed by applying a curable resin to the paper surface, the durability is lowered and the case cannot be used repeatedly.

Fifth, after the sheet built in the main body is cut, the sheet can be continuously pulled out only after the front lid is lifted and applied, which is troublesome to use.

The present invention has been devised to solve such problems, and the case material is made of synthetic resin, and a durable cut projection is integrally formed in the folded portion constituting the main body. The purpose is to allow the case to be used repeatedly and to always cut the sheet in a straight line.

Another object of the present invention is to form a housing space in the lid of the main body and the inwardly bent piece, and to form a movable piece on the front plate that moves within the range of the housing space so that the lid is not repeatedly opened and closed. Another object is to enable cutting while continuously pulling out the sheet from the main body.

According to an embodiment of the present invention for achieving the above object, the main body is made of a synthetic resin material in a case having a function of cutting a lapping material composed of a front plate, a bottom plate, a back plate, a lid, and a plurality of measuring plates. In the folded portion, which is a bent portion of the inwardly bent piece formed by connecting to the front plate constituting the main body, the cutting projections are continuously projected upward while being separated from each other by the connecting piece A wrapping material cutting function is provided, characterized in that the wrapping material placed in the main body is cut by a cutting protrusion formed so as to protrude upward at the folded portion. Is done.

The present invention has the following various advantages over the conventional apparatus.

First, the cutting projection that performs the function of the cutter is made of a synthetic resin material, and the case in which the sheet is built is folded so that the cutting projection is formed in accordance with the perfect shape of the rectangular parallelepiped as shown in FIG. Since the part will always maintain a straight line state, even if the sheet is cut by applying force, the shape of the folded part will not change, so that the sheet can always be cut linearly. Become.

Secondly, since the case is made of a rigid synthetic resin material, it has a perfect rectangular parallelepiped shape. Therefore, even if an external force is applied during distribution or storage, the case is not easily deformed.

Thirdly, since the cutting projections that function as a cutter are made of synthetic resin material, not only foils but also strong paper sheets can be easily cut without special post processing. It becomes like this.

Fourth, since the case is formed of a synthetic resin material, it is excellent in durability, and it is economical because only the sheet can be purchased and the case can be used repeatedly.

Fifth, after storing in a state where the lid is closed on the main body, the sheet can be pulled out and cut without opening the lid.

Sixth, when the sheet is cut, the sheet placed in the main body is cut while being pressed with a finger, so that the sheet can be cut linearly regardless of the amount of the wound sheet.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art to which the present invention pertains can easily implement the embodiments. The present invention can be embodied in various different forms and is not limited to the embodiments described herein. It should be noted that the drawings and the like are schematic and are not shown to scale. Relative dimensions and proportions, such as parts in the drawings, are shown exaggerated or reduced in size for clarity and convenience in the drawings, and any dimensions are merely exemplary And not limiting. The same reference numerals are used to indicate similar features in the same structures, elements or parts shown in more than one drawing.

3 is a development view showing the case of the present invention, FIG. 4 is a perspective view showing the case of the present invention, and FIG. 5 is an enlarged view of the “A” portion of FIG. In the invention, the material of the main body 51 constituting the case is made of a synthetic resin material unlike the conventional one, and the cutting protrusions 52 are continuously separated from each other by the connecting pieces 53 at the bent portions of the main body 51. Since it is formed so as to protrude upward, the wrapping material put in the main body 51 can be cut by the cutting protrusion 52.

As shown in FIG. 3, the cutting protrusion 52 is formed at the folding portion by a separate cutter (not shown) and pressed along the folding line 54 when pressing a material having a predetermined thickness. By folding the main body 51, the main body 51 protrudes upward as shown in FIG.

As shown in FIG. 5, the cutting protrusion 52 has a vertical surface 52a formed on one surface, and an inclined surface 52b formed on the other surface. The adjacent cutting protrusions 52 are connected pieces. 53, while maintaining a predetermined interval, the entire fold is formed.

At this time, one surface of the cutting protrusion 52 is formed as a vertical surface 52, and the other surface is formed as an inclined surface 52b inclined at a predetermined angle θ, but the angle θ of the inclined surface is 30 ° or less. If this is the case, the distance between the cutting protrusions 52 is so narrow that it is impossible to process the cutter that forms the cutting protrusions 52 using a tool. Since the performance decreases, it is preferable to form the inclined surface 52b so as to be inclined by 30 to 40 °.

The position at which the cutting protrusion 52 is formed can be determined at the first folding portion or the second folding portion as required. As shown in FIG. 4 shown as an embodiment of the present invention, the cutting protrusion 52 is provided. Are formed on the inwardly bent piece 56 and the first bent portion which is the bent portion of the front plate 57.

In one embodiment of the present invention, the protrusion height of the cutting protrusion 52 is set to 1.5 to 2.0 mm, but if the protrusion height is 1.5 mm or less, the pitch is too narrow and the sheet On the contrary, if the cutting performance of 55 is 2.0 mm or more, the pitch is too wide and the cut surface becomes rough.

The material of the main body 51 is polypropylene (PP) or polyethylene terephthalate (PET), which is harmless to the human body, and the thickness is 0.4 to 0.45 mm. It is more economical because it minimizes the amount of material used while maintaining.

As shown in FIG. 3, the case of the present invention is configured such that an inwardly bent piece 56 is extended to the front plate 57, and a part of the upper part opened by the lid 58 is bent inwardly. It is in the form of being closed by a piece 56.

At this time, if the downward bent portion 56a is formed in the inwardly bent piece 56, the downward bent portion 56a pushes the sheet 55 pulled out from the main body 51 as shown in FIG. It has an advantage that it can be cut by the cutting protrusion 52 while being pulled out more stably.

A first measuring plate 59 having first and second auxiliary measuring plates 60 and 61 is formed at both ends of the main body 51, and a locking hole 59a is formed in the first measuring plate 59.

And the 2nd measuring board 62 is formed in the both ends of the inward bending piece 56, The 3rd auxiliary measuring board 66 is formed in the said 2nd measuring board 62 so that folding is possible, The third auxiliary measuring plate 66 is formed with an embossing protrusion 66a.

Fastening pieces 63 each having an elastic piece 63a are formed at both ends of the lid 58 so that the main body 51 forms a rectangular parallelepiped shape over a locking hole 59a formed in the first measuring plate 59.

Accordingly, as shown in FIG. 9, after the first, second, and third auxiliary measuring plates 60, 61, and 66 are folded at 90 degrees along the folding line 54 of the first and second measuring plates 59 and 62, respectively. After the front plate 57 and the bottom plate 65 are folded at 90 ° along the fold line 54, the third auxiliary measuring plate 66 is positioned so as to be positioned above the second auxiliary measuring plate 66. 62 is automatically positioned on the inner surface of the first measuring plate 59.

In this state, when the first auxiliary measuring plate 60 is brought into close contact with the inner surface of the second measuring plate 62, the lower end of the first auxiliary measuring plate 60 is applied to the embossing protrusion 66a formed on the third auxiliary measuring plate 66. Thus, the housing whose rear surface is opened by the inwardly bent piece 56, the front plate 57, and the bottom plate 65 is completed.

Thereafter, after the sheet 55 is put into the internal space of the main body 51, the elastic piece 63a formed on the fastening plate 63 covering the back plate 64 and the lid 58 with the front end exposed to the outside of the housing. If it is applied to the locking hole 59a formed in the first measuring plate 59, the assembly of the case of the present invention is completed as shown in FIG.

On the other hand, storage spaces 67a and 67b are formed so as to overlap each other at an intermediate portion of the lid 58 and the inwardly bent piece 56 constituting the main body 51, and the front plate 57 includes the storage spaces 67a and 67b. A movable piece 68 that moves within the range is formed.

At this time, it is preferable that the width b1 of the accommodation space 67b formed in the inwardly bent piece 56 is set wider than the width b2 of the movable piece 68. However, when the movable piece 68 is pushed, this is the accommodation space 67b. It is for making it move freely to the inside.

The shape of the movable piece 68 is an upper, lower, and narrow shape, and a through hole 69 is formed at the end. However, even if the movable piece 68 is repeatedly pressed, an incision (break) phenomenon occurs at the end. This is to prevent it from being generated.

In FIG. 3, a part indicated by a solid line is a cutting line 70, and a part indicated by a dotted line is a fold line 54.

The operation of the present invention configured as described above will be described as follows.

First, when a synthetic resin material in the form of a sheet as shown in FIG. 3 is pressed, the sheet is cut into a predetermined shape along the cutting line 70, and at the same time, the fold line 54 is pushed inward. A cutting projection 52 is entirely formed by a separate cutter (not shown) at a bent portion which is a bent portion of the bent piece 56 and the front plate 57.

After pressing in this manner, the lid 58, the back plate 64, the bottom plate 65, the front plate 57, the inwardly folded piece 56, and the downward folded portion 56a are sequentially folded along the fold line 54, and The first measuring plate 59 and the first, second, and third auxiliary measuring plates 60 and 61, and the second measuring plate 62, the third auxiliary measuring plate 66, and the fastening piece 63 are folded along the other folding lines 54, respectively. .

Thereafter, the second auxiliary measuring plate 61 folded 90 degrees from the first measuring plate 59 along the folding line 54 is brought into close contact with the inner surface of the front plate 57, and then the inwardly bent piece 56 is folded. After the third auxiliary measuring plate 66 folded 90 ° from the second measuring plate 62 is brought into close contact with the second auxiliary measuring plate 61, the first auxiliary measuring plate 60 is brought into close contact with the second measuring plate 62. The lower end of the first auxiliary measuring plate 60 is applied to the embossing protrusion 66a. Such an assembling operation is performed on both sides of the main body 51 in the same manner.

After the assembly work of the first and second measuring plates 59 and 62 and the first, second and third auxiliary measuring plates 60, 61 and 66 is completed in this way, the inwardly bent piece 56 and the front plate 57 are used. And, since the housing whose back surface is opened by the bottom plate 65 is completed, the sheet 585 to be used is put inside the housing so that the tip is exposed to the outside of the housing. By applying the elastic piece 63a formed on the fastening piece 63 so as to cover the back plate 64 and the lid 58 to the locking hole 59a formed on the first measuring plate 59, the assembly operation of the packaging box is completed.

In this state, when the sheet 55 accommodated in the main body 51 is to be cut, the sheet is pulled out by a necessary length. At this time, the inwardly bent piece 56 is directed downward on the outer peripheral surface of the sheet 55. Since the bent portion 56a is tightly connected, the sheet 55 is stably pulled out.

After pulling out the sheet 55 by a desired length in this way, after pressing the lid 58 with one hand and then holding the sheet 55 with the other hand and pressing it downward, the synthetic resin formed in the folded portion of the sheet 55 It is cut cleanly in a straight line by the cutting protrusion 52 made of material.

After the sheet 55 is pulled out from the main body 51 by a necessary length and cut, the remaining sheet 55 is housed inside the main body 51 by the lid 58 and the downward bent portion 56a, and thus is contaminated by dust or the like. The phenomenon will also be prevented.

On the other hand, when the sheet 55 accommodated in the main body 51 is to be pulled out and cut again, as shown in FIG. 10, the movable piece 68 is formed in the form of a one-dot chain line inward along the arrow direction. By pushing and allowing the movable piece 68 to be accommodated in the accommodating spaces 67a and 67b, the "K" portion of the sheet 55 accommodated inside the main body 51 is grasped along the arrow direction without opening the lid 58. It is possible to pull out the desired length by pulling.
