Description

Case with lapping material cutting function

The present invention relates to a case in which a wrapper of this type of wrapping material used for suppressing the emanation of odor and maintaining freshness and cleanness when storing or transporting food or vegetables, fruit, etc. is stored in a refrigerator. In more detail, the present invention relates to a case having a lapping material cutting function for remarkably improving the material and configuration of the case to accurately and conveniently cut the lapping material without using a separate cutter.

In general, as a wrapping material used for food (food or vegetable, fruit, etc.) packaging, etc., a wrap film made of a synthetic resin, aluminum foil, a paper sheet for a kitchen, and the like are known.

The ramping material is manufactured in a thin sheet shape and then rolled into a roll shape to be accommodated and sold in a case made of paper. The user pulls out a wrapping material (hereinafter referred to as 'sheet') in a rolled amount as needed. It is cut and used.

Currently used case is made of paper material and has a rectangular parallelepiped structure that can be opened and closed the cover, one side is fixed with a metal cutter equipped with a sawtooth cutting blade is fixed to the user to open the cover The sheet is cut by pulling it out to length and pulling it out, then touching the cutter blade and pulling it down.

However, since the case cuts the sheet by a metal cutting blade, the user often inadvertently tears his hand, and the sheet is removed from the case in the process of cutting the sheet. Problems such as not cutting in a straight line by moving within.

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

1A and 1B are perspective views showing a conventional embodiment, and FIG. 2 is an exploded view of a conventional storage container with a saw blade, and covers a lid covering an upper surface opening of a container body A and a container body A addressed thereto. (B) is comprised from blank P, such as a thick paper and a cardboard, for example.

In the blank P, the front part A1, the bottom part A2, the back part A3, and the left and right side parts A4 which make up the container main body A speak as shown in the expanded view of FIG. In addition, the upper lid portion B1, the front lid portion B2, and the left and right lid portions B3 constituting the lid B are spoken through cut lines.

An ablation piece B4 is extended with the sawtooth cutting line 1 interposed between the front end of the front cover part B2, and the sawtooth cutting line 1 is described later at the time of cutting the blank P. As shown in FIG. It is punched together with a nick (3).

In the middle of the sawtooth cut line 1, a plurality of teeth 3 larger than each of the saw blades 2a of the saw blade 2 are provided, and a nick formed at the tip of these teeth 3 ... The blank P is bent by 3a ..., and is bendably connected, and any of the

cut surfaces

1a and 1b which the toothed cutting line 1 opposes the nick 3a ... of the tooth 3 ... It is comprised by protruding from one side toward the other.

In the case of the example of illustration, although the shape of the said tooth | gear 3 ... was shown by the mountain larger than each mountain blade of the saw blade 2, it is not limited to this, For example, other shapes, such as a substantially semi-circle, can be applied.

And in the manufacturing process of the storage taking-out container with a saw blade, the blank P is made by making into the boundary between the both cut surfaces 1a (1b) of the said serrated cutting line 1, and the nicks 3a ... of the teeth 3 ... By folding and overlapping, both

cutting surfaces

1a and 1b of the sawtooth cutting line 1 are exposed in two stages, and both

cutting surfaces

1a and 1b of the sawtooth cutting line 1 Curable resin (R) is apply | coated to the said exposed part in an exposed state, and it hardens.

In the case of this embodiment, as shown to FIG. 1A and 1B, the front cover part B2 and the ablation piece B4 of the cover body B are folded, and the sawtooth cut line 1 of the side of the ablation piece B4 is overlapped. While exposing the cut face 1a of the cut face 1 and the cut face 1b of the sawtooth cut line 1 on the cover body B side, respectively, the exposed

cut face faces

1a and 1b and the blanks continuous thereto are exposed. Curable resin R is apply | coated to the front and back surfaces of P) by strip | belt shape with the application means R1, such as a roller and a brush, for example.

To explain this in detail, the teeth 3 are cut from the cutting surface 1a of the sawtooth cutting line 1 on the side of the cutting piece B4 toward the cutting surface 1b of the sawtooth cutting line 1 on the cover B side. ... and the tooth 3a ... of the cutting piece B4 side in the state which protruded the nick 3a ... of them, and cut | disconnected the cutout piece B4 and the front cover part B2 of the cover body B, and overlapped. From the cutting surface 1a of the line 1, the cutting surface 1b of the serrated cutting line 1 by the side of the cover body B in which the saw blade 2 is formed is projected in two steps.

Moreover, in order to shorten the hardening time as said curable resin (R), ultraviolet curable resin, such as an acrylic polyester copolymer, an acrylic epoxy copolymer, or an acrylic urethane copolymer, or the like type of electron beam (EB) hardening type, It is preferable to use resin.

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

Next, the operation of such a storage take-out container with a saw blade is demonstrated.

First, as shown to FIG. 1A and FIG. 1B, the front cover part B2 and the ablation piece B4 of the cover body B are both

cut surfaces

1a, 1b, and sawtooth of the sawtooth cutting line 1. 3…) are folded and overlapped with the nicks 3a… as a boundary.

Thereby, the cutting surface 1a of the sawtooth cutting line 1 of the cutting piece B4 side, and the cutting surface 1b of the sawtooth cutting line 1 of the cover body B side are exposed, respectively.

And when curable resin R is apply | coated in strip | belt shape by the application | coating means R1 to both front and back surfaces of the both

cutting surfaces

1a and 1b of the serrated cutting line 1 exposed, and the blank P which is continuous to it. The curable resin R penetrates into the

entire cut surfaces

1a and 1b of the sawtooth cut line 1.

As a result, even the simple resin coating method hardens the front end surface of the saw blade 2.

Moreover, the cutting surface 1b of the sawtooth cutting line 1 of the cover body B side in which the saw blade 2 is formed rather than the cutting surface 1a of the sawtooth cutting line 1 of the cutting piece B4 side Curable resin (R) is apply | coated in the state which protruded in two steps.

As a result, the curable resin R sufficiently penetrates both the front and rear surfaces of the cutting surface 1b on the side of the saw blade 2 and the blank P subsequent thereto, so that the entire tip of the saw blade 2 can be reliably cured. .

However, in the conventional case having such a structure, the blank is folded and overlapped with the sawtooth cut line and the nick of the saw tooth as a boundary, and the curable resin is exposed to the exposed portion in a state where both cut surfaces of the sawtooth cut line are respectively exposed in a stepped shape. The coating has a merit that it is possible to reliably harden the front end surface of the saw blade, but the following various problems have arisen.

First, although both cut surfaces of the sawtooth cut line are coated with a resinous resin on a blank made of paper material, there is a limit in maintaining firm strength, so that the sheet cannot be cut straight.

Secondly, if the blank is inadvertently deformed during distribution or storage, the cutter will lose its function and thus the sheet cannot be cut.

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

Fourth, as the cutter is formed by applying a curable resin to the surface of the paper, the durability decreases, and thus the case cannot be used repeatedly.

Fifth, after cutting the sheet embedded in the main body, the front cover portion must be lifted so that the sheet can be continuously drawn out, which is cumbersome to use.

The present invention has been made to solve such a problem, the material of the case is made of synthetic resin and the bending portion constituting the main body integrally formed cutting protrusions integrally so that the case can be used repeatedly and at the same time the sheet The aim is to be able to cut straight.

Another object of the present invention is to form a receiving space in the cover and the inward bending piece of the main body and the front plate to form a movable piece moving in the range of the receiving space while continuously withdrawing the sheet from the main body without opening and closing the cover repeatedly It is to be able to be stolen.

According to an aspect of the present invention for achieving the above object, in the case having a wrapping material cutting function consisting of a front plate, a bottom plate, a back plate, a cover, a plurality of side plates, the body is formed of a synthetic resin material and the body The bent portion of the inward bending piece that is formed in series with the front plate forming the cutting projections are continuously projected upwards while being spaced apart from each other by the connecting piece so that the wrapping material contained in the body is projected upward by the cutting projections formed in the bending portions. Provided is a case having a wrapping material cutting function, which is configured to be cut.

The present invention has several advantages over the conventional apparatus as follows.

First, since the cutting protrusion functioning as a cutter is made of synthetic resin material and the case in which the sheet is built maintains the rectangular parallelepiped shape completely as shown in FIG. Even if the sheet is cut off, the shape of the bent portion does not change, and thus the sheet can always be cut straight.

Second, the case is not only made of a solid synthetic resin material, but also takes a perfect cuboid shape, so that the case is not easily deformed even when external force is applied during distribution or storage.

Third, the cutting protrusions functioning as cutters are formed of synthetic resin material, so that a tough sheet of paper as well as a foil can be easily cut without additional post processing.

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

Fifth, since the cover is stored in the main body in a closed state, the sheet is pulled out and cut without opening the cover.

Sixth, when cutting the sheet while cutting the sheet contained in the main body with a finger, it is possible to cut the sheet in a straight line regardless of the wound amount of the sheet.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. It is noted that the figures are schematic and not drawn to scale. The relative dimensions and ratios of the parts in the figures have been exaggerated or reduced in size for clarity and convenience in the figures and any dimensions are merely exemplary and not limiting. And the same reference numerals are used to refer to similar features in the same structure, element or part shown in more than one figure.

3 is an exploded view showing a case of the present invention, Figure 4 is a perspective view showing a case of the present invention, Figure 5 is an enlarged view "A" of Figure 3, the present invention is a material of the body 51 constituting the case Unlike the related art, it is made of a synthetic resin material, and the cutting protrusions 52 are formed on the bent portion of the main body 51 so as to continuously project upwardly while being spaced apart from each other by the connecting piece 53 to wrap the material contained in the main body 51. Characterized in that it can be cut by the cutting projection (52).

As shown in FIG. 3, the cutting protrusion 52 is simultaneously formed in the bent portion by a separate cutter (not shown) when pressing a material having a predetermined thickness, and is formed along the fold line 54. As the main body 51 is folded, the main body 51 protrudes upward as shown in FIG. 6.

As shown in FIG. 5, the cutting protrusion 52 has a vertical surface 52a formed on one surface thereof, and an inclined inclined surface 52b formed on the other surface thereof. The adjacent cutting protrusions 52 are connected to each other by the connecting piece 53. It is formed over the entire bent portion while maintaining a predetermined interval.

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 by a predetermined angle θ, the angle θ of the inclined surface is 30 ° or less Since the surface of the cutting protrusions 52 is narrow, the cutter forming the cutting protrusions 52 cannot be processed by using a tool, and when the angle is 40 ° or more, the cutting protrusions 52 are far apart and the cutting performance of the sheet 55 is increased. Since it will fall, it is preferable to form the inclined surface 52b inclined 30-40 °.

Where the cutting protrusion 52 is formed may be determined as the first bent portion or the second bent portion, if necessary, as shown in Figure 4 of an embodiment of the present invention the cutting projection 52 inward bending piece 56 ) And the first bent portion of the front plate 57 is formed as a whole.

In one embodiment of the present invention, the protrusion height of the cutting protrusion 52 is set to 1.5-2.0 mm. If the protrusion height is 1.5 mm or less, the pitch is too narrow so that the cutting performance of the sheet 55 falls, and vice versa. If it is 2.0 mm or more, the pitch is too wide and the cutting surface becomes rough.

The material of the main body 51 is made of polypropylene (PP: Polypropylene) or polyethylene terephthalate (PET), which is harmless to the human body, and the thickness is 0.4-0.45 mm while maintaining the durability of the cutting protrusion 52. It is more economical because it minimizes the amount of material used.

The case of the present invention is configured to extend the inward bending piece 56 to the front plate 57, as shown in Figure 3 is closed by the inward bending piece 56, a part of the upper portion opened by the cover 58 Taking shape.

In this case, when the downward bending portion 56a is formed in the inward bending piece 56, the downward bending piece 56a presses the sheet 55 drawn out from the main body 51 as shown in FIG. While having a more stable withdrawal has the advantage that can be cut by the cutting projection (52).

First side plates 59 having first and second

auxiliary side plates

60 and 61 are formed at both ends of the main body 51, and locking holes 59a are formed in the first side plates 59, respectively. .

The second side plate 62 is formed at both ends of the inwardly bending piece 56, and the third side plate 66 is formed to be foldable on the second side plate 62. An embossing protrusion 66a protrudes from 66.

In addition, fastening pieces 63 having elastic pieces 63a are formed at both ends of the cover 58 so as to catch the engaging holes 59a formed in the first side plate 59 so that the main body 51 forms a rectangular parallelepiped shape. .
