Description

      The present invention relates to a tray 1A used as a shape-retaining material for a bag of food, provided with a cut 20 for separating the knob 2A on a thin flat plastic.

      Conventionally, there is no tray provided with a cut 20 for separating the knob (2A) on a tray that is used as a shape-retaining material for a bag-shaped food molded into a thin shape. In the case where the cut was provided, there was only a cutting line position for facilitating separation of a plurality of container recesses.

[Patent Document 1] Japanese Patent Application Laid-Open No. 10-273125 “Food Container” proposes that a cut is provided between a plurality of depressions for food containers.
[Patent Document 2] Japanese Patent Application Laid-Open No. 2008-56331 “Plastic Product with Line-shaped Cuts” proposes a technique that prevents a reduction in strength even when cuts are provided. Other similar ones have been proposed.

      The thinly formed trays are mainly those formed by vacuum forming or pressure forming. A familiar consumer is a tray that is used as a shape-retaining material for bags of food. After opening the trays for food in bags, the trays are no longer necessary and are discarded. However, these trays are provided with cuts for cutting the knobs 2A so that the knobs 2A can be separated from those that are no longer needed. It is also a meaningful thing to use resources effectively as it is an effective use of resources.

Japanese Patent Laid-Open No. 10-273125, “Food Container” Japanese Patent Application Laid-Open No. 2008-56331 “Plastic Products with Line-shaped Cuts”

Some of the foods in the bag are fried foods such as squid and sweet potato, stuffed with oil and sugar like a donut, sauce on the surface like a baked squid with sauce (for seasoning Etc. with a sticky seasoning juice). After grabbing them with your hands, you must wipe them with tissue paper, hand wipes, squeezers, towels, etc., or wash your hands with soap to remove any oil etc. adhering to your hands. If you don't like oil on your hands, you should have chopsticks and tongs. Also, chopsticks etc. must be washed after use.

However, chopsticks and tongs are not always at hand when eating packaged foods. It would be convenient if the shape-keeping material tray contained in the food in the bag had a cut and was taken out and a pinch such as a tong analog could be easily obtained.

The tray for the cut may be independent of the attached product. For example, a cutout for a “letter plate” may be provided on a tray such as a shape retaining material attached to a product used by elementary / junior high school students. “Erase plate” was used for drawing before CAD became popular. Holes of various shapes were made on a thin stainless steel plate according to the shape and size of the wire to be erased. Yes, it is convenient that if you put this hole on the part you want to erase and erase it with an eraser, it will remain in place other than the hole. The stainless steel plate was opaque and could not be seen underneath, so it took time to find the place to erase. Some stainless steel plates had numerous small holes so that the bottom could be seen through, but it was expensive. The point tray is colorless and transparent, and many are thin, so it is suitable for the eraser.

      At present, trays such as shape-retaining materials used for bags are often processed such as cutting into thin plastic moldings formed by vacuum forming or pressure forming. At the time of this cutting process, since it is sufficient to attach a cutting blade for a cut for cutting the knob 2A, the cost increase is small.

      The problem to be solved by the present invention is that, after opening or after use, such as a shape-preserving tray in a bag of food, put a cut for taking out the knob 2A on a thing to be thrown away, take out a useful item, and use it effectively Is to provide a thin tray.

      The present invention is characterized in that a slit for taking out the knob 2A is provided in a thin tray to be discarded after opening or after use.

    A tray 1A used as a shape-retaining material for packaged food according to claim 1 is a thin plate-like plastic provided with a slit 20 for taking out the knob 2A.

Any tray can be used as long as it is used until opened by the consumer and discarded after use. It is thin because of the cut.

Any useful item useful for life can be literally useful, but it may or may not be related to the product for which the tray is used. For things that are related, in the shape-keeping material contained in the bag food, a cut is made to take out pinching tools such as tongs, and the fried food, squid with sauce, etc. with the clipping device separated It is convenient that you don't get your hands dirty. Among the unrelated ones, there are the “eraser” mentioned in “Problems”.

The perforation may be perforated first, but a thin plastic sheet is difficult to use because of the risk of derailment. It is better to use a one-way cut to prevent derailment and a two-way break to prevent derailment. The derailment prevention one-way break, which will be described in detail in Examples below, is a combination of breaks such as a Y-shape or a T-shape. The derailment prevention bi-directional cut is also described in detail in the examples described later, but is a combination of linear ends having a V shape or U shape.

Although it was description of the knob according to the old claim 2, since the old claim 2 was deleted, the content of this paragraph is deleted.

The knob according to claim 2 is a thing obtained as a useful material, even if the table surface is soiled, the soiling does not stick to the sandwiched portion. The portion of the handle 22 that contacts the table surface is not limited to a straight line, and may be a curved line that is convex upward or a bent straight line. The bent part 23 and the fulcrum 221 of the handle part 22 may be in contact with the table surface.

The contact point far from the bent portion 23 of the handle portion 22 corresponds to the fulcrum described in (E) of [0031] of the first embodiment.

Although it was description of the knob 2A which concerns on the old claim 3, since the old claim 3 was correct | amended to Claim 1, the content of this paragraph is deleted.

“Estimated to fit the shape and size of the part to be erased” of the eraser hole 27 means that it may be changed freely depending on the use and purpose of the eraser plate. It varies greatly depending on whether it is for drafting or notebook, and the notebook also varies depending on the department and grade. What is necessary is just to predict various uses and to judge that it is appropriate. The number and arrangement of the eraser holes 27 may be freely changed. Thin and transparent sheets are ideal for erasers. If it is rubbed with an eraser and becomes cloudy during use, the next eraser can be cut off. As will be described later in Example 6 [0057], if a styrofoam tray is also cut, it can be used as a name tag for vegetables and flowers in a home garden. The styrofoam tray is thick but fragile, so it can be easily removed by making a cut. In the present specification, in order to make the cut easy to cut, the thin plastic molding and the thickness are limited, but the original purpose is the ease of cutting the cut rather than the thickness. Therefore, although the polystyrene foam tray is thick, it is fragile and easily disengaged from the cut as described above. In this specification, the polystyrene foam tray is also treated as a thin plastic molding.

The invention of claim 1 has an effect of obtaining a useful product of the knob candy 2A by opening the bag containing foods from the tray that is no longer needed by cutting the cut 20.

Although the effect of the invention of the old claim 2 was described , since the invention of the old claim 2 was deleted, the content of this paragraph is deleted.

Although the effect of the invention of the old claim 3 was described , since the invention of the old claim 3 was deleted, the content of this paragraph is deleted.

It is the top view and perspective view which show the tray which provided the cut of Example 1, the knob tool, and the cut. It is the top view, perspective view, and side view which show the tray which provided the cut | interruption of Example 2, and the knob obtained from this. It is the perspective view and top view which show the container provided with the cut of Example 3, a tray, and a coaster. It is a top view which shows the windmill obtained from the tray provided with the cut of Example 4, and a barge. It is a top view which shows the eraser board and scissors obtained from the container and the tray which provided the cut of Example 5. FIG. It is the top view and perspective view which show the tray of Example 6, a container, a binding tool, a holding tool, and a name tag.

After using the product, the purpose of taking out useful items from the discarded trays and making effective use of them was realized by providing cuts for taking out useful items.

The tray provided with the cut | disconnection for useful goods of Example 1 is demonstrated based on FIG. FIG. 1A is a plan view showing a tray 1A provided with a cut 20 for obtaining a knob 2A such as a tongue. The length of the tray 1A is omitted. Reference numeral 21 denotes a sandwiching portion, 22 denotes a handle portion, 23 denotes a bent portion, and 24 denotes an arrow (a raised shape).

When the knob 2A surrounded by the cut 20 is pulled to the right as indicated by the arrow, the knob 2A is separated from the tray 1A by the cut 20 which is a one-way cut to prevent derailment. When folded in half at the center bent portion 23 (indicated by a dotted line), a tongue-shaped knob 2A is obtained. Derailment prevention one-way cuts are formed by arranging elongated T-shaped cuts. If you pull to the right as shown by the arrow, you can cut without derailing. The bent portion 23 has a dotted line in the drawing, but nothing is required. Even if a crease or the like is not attached in advance, that is, nothing is done, if folded, the folded state is maintained.

(B) is a top view which shows another knob 2A provided in tray 1A. A frame indicating the tray 1A is omitted. The difference from that shown in (A) is that the central bent portion 23 has a small semicircular cross section as shown in the cross sectional view in the enlarged circle. For this reason, it is easy to bend | fold at the bending part 23. FIG. The derailment prevention one-way cut 20 is different from the one shown in (A), and is changed from an elongated T shape to an elongated Y shape. Others are the same as those of (A).

The boundary between the sandwiching part 21 and the handle part 22 is not clear, but the part close to the tip is the sandwiching part 21 and the part close to the bent part 23 is the handle part 22. Even if it does not do anything like (A), the bending part 23 will bend easily if it bends and will keep the state.

(D) is a top view which shows the other knob 2A provided in tray 1A. Has the two side-by-side form a hexagon, a bend 23 bending the central dotted line portion. In the drawing, a dotted line is drawn, but in practice, nothing needs to be done. The derailment prevention one-way cut 20 is formed by arranging the V-shaped portions of the elongated Y-shaped cut into U-shaped portions. The bent portion 23 is bent to make the knob 2A.

(E) shows a was placed broken knob member 2A, separated from the tray 1A of (D) bent at bent portion 23, and the knob member 2 of the side shape is hexagon, on a plane such as a table It is a perspective view. You were a handle portion 22 near the bent portion 23 folded the dotted line bisecting the side shape hexagon, a nip 21 towards the farther from the described bending portion 23. The tip far from the lower bent portion 23 in contact with the handle 22 on the table is defined as a fulcrum 221. With the fulcrum 221 at the center, the store opens to the left and right due to the weight of the clip portion 21 and the handle portion 22. As shown in the drawing, in order for the handle portion 22 to contact the table, the size of the handle portion 22 must be determined so that the handle portion 22 becomes heavier. As described above, when the handle portion 22 is in contact with the table, the pinching portion 21 does not touch the table, and even if the table surface is dirty, the pinching portion 21 that touches the food can prevent the adhesion of dirt. . Strictly speaking, not the weight difference between the pinching portion 21 and the handle portion 22, the handle portion 2 2 side is heavier than the vertical line passing through the fulcrum 221, a handle portion 2 2 As (E) Figure It is in contact with the table.

(F) is a top view which shows the derailment prevention one-way break 20. FIG. In either case, pulling in the direction of the arrow cuts without derailing. These are shown in (A), (B), and (D) of FIG.

(G) is a top view which shows derailment prevention bidirectional cut 20. FIG. These are cuts that can be separated without derailing from either the left or right side. An example of use will be described in the second embodiment.

  The effect shown in Example 1 is that the knob 2A is easily removed from the tray 1A, and the tong-shaped knob 2A is easily formed by bending at the bent portion 23, and the food in the bag is pinched. There is.

The tray provided with the cut | disconnection for useful articles of Example 2 is demonstrated based on FIG. The knob 2 </ b> A according to the second embodiment has a reinforcing rib 25. The reinforcing rib is provided to reinforce the thin plastic sheet. The cross-sectional shape is a semicircular or U-shaped groove.

2A is a plan view showing a container 1B in which a knob 2A with a reinforcing rib 25 is surrounded by a derailment preventing bidirectional cut 20. FIG. The reinforcing rib 25 is a groove having a U-shaped cross section as shown in the enlarged view in a circle. The reinforcing rib 25 may be provided outside the cut line 20, that is, on the remaining portion of the container 1B. A broken line 23 is indicated by a dotted line in the center.

(B) is a perspective view showing a product obtained by cutting the knob 2A shown in (A) by a cut line 20 and bending it at a bent portion 23. FIG. To use it, food or the like is sandwiched between the sandwiching portions 21 and carried to a necessary place. The handle portion 22 may be pinched with fingers from the outside, or the pinching portion 21 may be pinched directly with fingers. Since the reinforcing rib 25 is attached, the handle portion 22 and the sandwiching portion 21 are not easily bent.

(C) is a perspective view showing a place where a knob 2 </ b> A cut off from a tray and bent at a bent portion 23 is placed on a table. This is the same as that in Example 1 (E) in which the reinforcing rib 25 is added. Similar to the first embodiment, the handle 22 is heavier than the pinching portion 21 and the pinching portion 21 does not get dirty even if the table is dirty. Usage is the same as in (B).

(D) is a side view showing a state in which the pinching portion 21 of the knob tool 2 in (C) is deformed, and is changed from a square shape to a shape close to a circle and placed on a table. Others are the same as those of (C).

(E) is a side view showing a modification of (D), in which a knob 2A having a pinch portion 21 larger than a handle portion 22 is placed on a table. It is necessary that the handle 22 side is heavier than the perpendicular line passing through the fulcrum 221, including part of the sandwiching portion 21. Others are the same as those of (D). The fulcrum 221 is the end of the sandwiching portion 21 near the handle portion 22, but even if it is the sandwiching portion 21 or the end near the handle portion 22, even if it touches a dirty table, the food in the sandwiching portion 21 There is no dirt on the part that sandwiches.

A thinly molded plastic molded article provided with the cut of Example 3 will be described with reference to FIG. (A) of FIG. 3 is a perspective view of the food container 1B provided with a cut 20 for the coaster 2B laid under the cup on the bottom surface. The coaster 2B has concentric irregularities. The cut 20 employs a one-way cut to prevent derailment. Concentric irregularities are omitted in the drawing.

(B) is a plan view of the coaster 2B shown in (A). As shown in the sectional view in the enlarged circle, the cross section is corrugated. Although it is not necessarily for food, if there is an extra space on the bottom or lid of a container made of thin plastic, the coaster is suitable because it does not take up much area and is thin. The coaster 2B may be a circle or a square.

(C) is a perspective view showing the tray 1A provided with the cut 20 of the box 2C. Some trays containing confectionery or the like are provided with small box-shaped recesses for subdivision. In order to use this recess as the box 2C, a cut 20 is provided at the boundary. If necessary, they may be separated and used as a continuous box 2C. It is better to provide a break 20 for preventing derailment, but the boundary part has a U-shaped cross section, so two parallel parts like the bent part of the egg (chicken egg) case. It may be a dotted line.

A thinly formed tray provided with the cuts of Example 4 will be described with reference to FIG. In Example 4, a cut for toys is provided. FIG. 4A is a plan view of the wind turbine 2D provided with a cut. The specific break situation is omitted. What is necessary is just to apply a thin plastic molding to a tray or a container. It shows a state of being cut along the cut line. The material of windmill 2D is shown. Open a hole 27 in the center of the square. Cuts 26 are made from each vertex of the square toward the center. A hole 27 is formed in the portion where the cut 26 of each vertex is made.

It can be applied to both trays and containers as long as there is a large area on the bottom or lid.

(C) is a top view of what provides the cut for the barge 2E. Similar to (A), the specific break situation is omitted. What is necessary is just to apply a thin plastic molding to a tray or a container. It shows a state of being cut along the cut line. Two parallel cuts 26 are made from both short sides of the rectangular boat 2. An insertion 26A is provided on one of the cuts 26 and the long side of the rectangle.

(D) is a top view which shows what assembled the material of the tugboat 2E of (C) into the tugboat 2E. When the fittings 26A near each short side are fitted and combined with each other, the tugboat 2E is obtained. Urban children usually don't see bamboo leaves and so on, so they can be used as a material to teach adults how they played in the past.

A thinly molded plastic molding provided with the cut of Example 5 will be described with reference to FIG. In Example 5, a cut for a learning tool is provided. FIG. 5A is a plan view of the bottom surface or lid of the container 1B provided with a cut for the eraser plate 2F. What is necessary is just a thin plastic molding. The cut 20 is perforated (dotted line). Each corner is rounded. Each side should be smooth because of the character of the eraser, so cut along the cut 20 with a knife or scissors. The container 1B need not be colorless and transparent, and may be colored as long as it is transparent.

How to use: After cutting along the cut line 20 with a knife or scissors, align the eraser hole 27A that matches the shape and size of the part you want to erase with the pencil and erase it with an eraser . There is an effect that the extra part is not lost. Since the material is transparent (usually colorless and transparent), it is easy to find the part you want to erase. Moreover, since it is thin, there is an effect that the eraser hits well. It is not necessary to be colorless and transparent, and may be colored or transparent.

(B) is a slightly modified version of the eraser plate 2F of (A). The cut line 20 can be cut with a knife or a scissors only by placing rounded ones at the four corners. This eraser plate 2F is for erasing one line or a certain portion of a note. Usually, there are 7 mm width type A and 6 mm width type B for university notebooks, but the erasing holes 27A are selected according to the width of the ruled lines, and the lines of a uniform length are erased. There is an effect that does not disappear outside the ruled line. In addition, an erasing hole 27A is selected in accordance with the rules and frames of the notebook for school children. Both (A) type and (B) type rules may be provided.

(C) is a top view of what provided the cut | interruption 20 for ridge 2G. As in (A), the gap 20 is cut with a knife or scissors. The small hole at the end of the presser piece 28 prevents tearing. A page is sandwiched between the presser piece 28 and the main body to form a heel. The part that appears on the page may be colored with an oil-based pen for distinction.

(D) is obtained by changing a part of the ridge 2G of (C). Both sides of the cut portion of the presser piece 28 are made jagged. It is jagged, making 栞 2G difficult to leave the page.

A thin molded plastic product provided with the cut of Example 6 will be described with reference to FIG. Example 6 is provided with a cut for other things. FIG. 6A is a plan view showing a lid of the container 1B provided with a cut 20 for the binding tool 2H. Any thin plastic molding may be applied. The cut 20 has a perforated shape. Since the binding tool 2H is handled by hand, it is preferable that the binding tool 2H be smooth. Therefore, the binding tool 2H is cut along the cut 20 with a knife or scissors. Several insets 26A are provided at the far ends of the long sides facing each other of the long rectangular binding tool 2H. To use, the objects to be bound are bundled, the binding tool 2H is turned, and the fittings 26A at both ends are fitted to each other and combined.

(B) is a perspective view showing a state in which the fittings 26A of the binding tool 2H of (A) are fitted to each other. Pass what you want to bind into this ring. Actually, the objects to be bundled are bundled, and the binding tool 2H is turned around them to fit the fittings 26A together.

(E) is a plan view of a styrene foam tray 1A provided with a cut 20 for a name tag 2J. Since it is a polystyrene foam, the cut 20 is like a perforation as shown in the figure, but the name tag 2J can be easily removed simply by pushing a part of the name tag 2J with a fingertip. In addition, when the cut line 20 is thin, even if water is put into the tray 1A, water does not leak due to surface tension. The removed name tag 2J is normally white in polystyrene foam, so it has the effect that it can be used as a vegetable or vegetable name tag in a vegetable garden by filling it in with an oil-based pen. Although the polystyrene foam is thick, it is fragile and can be easily removed by holding the cut. In the present specification, in order to make the cut easy to cut, the thin plastic molding and the thickness are limited, but the original purpose is the ease of cutting the cut rather than the thickness. Accordingly, although the polystyrene foam tray is thick, it is fragile and easily disengaged from the cut as described above. In this specification, the polystyrene foam tray is also treated as a thin plastic molding.

The thin tray provided with a cut for separating the useful material of the present invention can be applied to a shape-retaining material for a bag of food.
