Description

  The present invention relates to a packaged food, and more particularly, to a packaged food that is sold in a state of being enclosed in a packaging bag and can be eaten as if it is left as it is immediately after opening.

  In recent years, convenience stores and supermarkets sell various cooked foods such as rice balls, hamburgers, hot dogs, sandwiches, etc. in individual packaging, and can be eaten as soon as they are opened. Many foods are sold. As an example of such a packaged food, there is a packaged rice ball (see, for example, Patent Document 1).

  Patent Document 1 discloses a heat-weldable transparent plastic film based on polypropylene or the like printed with a trade name or various patterns, or a base material made of Japanese paper or pseudo-Japanese paper with heat of polyethylene or the like. There is disclosed a packaged rice ball in which a rice ball is housed and sealed in a bag made of a heat-welding packaging material on which a plastic synthetic resin layer is laminated.

JP 2006-20556 A

  The above-described rice ball containing the bag described in Patent Document 1 has a lateral seal portion extending in the lateral direction from the left end portion to the right end portion on the back side of the bag. The lateral seal portion is formed so as to extend like a bag from the bag body, and is secured by a quality label in a state of being bent along the surface of the bag body. The lateral seal portion is provided at a position below 1/2 of the bag height on the back side of the bag.

  In addition, an opening notch is provided at the left end or the right end that is 1/2 or more of the bag height as an opening means that enables the bag to be opened in the transverse direction. Further, a space portion is provided as a grip allowance that can be handled by gripping the upper portion of the bag without touching the rice ball from the upper end of the rice ball to the upper end portion of the bag with the bag containing the rice ball standing. That is, the rice balls are housed near the lower end inside the bag, and an opening notch is provided near the upper end of the rice balls housed in the bag.

  In this case, when opening is performed so as to cross the bag using the opening notch as an opening start point, the packaging material remaining below remains in a state of covering substantially the whole rice ball. Since the rice balls can be held by hand through the packaging material left below, both ease of eating and hygiene can be achieved.

  However, when the opening notch is provided near the upper end of the rice ball housed in the bag as in Patent Document 1, the packaging material left below immediately after the bag is cut from the opening notch is opened. It is in a state of covering the whole, and it is necessary to increase the exposed area of the rice ball by lifting the rice ball inside or turning the end of the cut line of the packaging down before the first bite Become.

  In addition, when the cut is made so that it crosses the bag starting from the opening notch, the cut line ideally runs sideways, but in reality the cut line has a different trajectory than the ideal due to various variables. Draw and run. Such variation factors include, for example, the position of the bag gripped by the worker performing the opening operation, the force applied by the worker to each gripping position, the direction of easy tearability of the bag material, interference with the contents, Etc. are considered.

  In the example of Patent Document 1, since an ideal cut line is set near the upper end of the rice ball, if the cut line flows above the ideal cut line and travels above the bag, the rice ball packaging material immediately after opening The coverage area due to becomes wider, and the work time required for the first stroke after opening becomes longer. In addition, as mentioned above, interference with the contents is also assumed as a variation factor of the cut line, so the cut line that runs near the top of the rice ball is more than the ideal cut line due to interference with the rice ball that is the content. The probability of traveling and traveling upwards of the bag is very high.

  The present invention has been made in view of the above-mentioned problems, and enables a first meal immediately after opening a bag-like food that is sold in a sealed state and can be eaten as it is immediately after opening, that is, An object of the present invention is to improve the first bitterness assurance (hereinafter referred to as “first byte (FB) assurance”) immediately after opening the packaged food.

  One aspect of the present technology is a packaged food in which fast food food is enclosed in a packaging bag in an individually packaged state, and a cut line running prevention provided in a line so as to cross the back surface of the packaging bag And the fast bite portion of the fast food food enclosed in the packaging bag are on the opposite side across the cut line travel prevention portion, and the end of the fast food food on the opposite side and the cut And a bag opening food provided between the line travel prevention unit.

  In this packaged food, a cut line running prevention unit is provided on the back surface of the packaging bag so as to block between the opening means and the first bite unit of the fast food product. The cut line travel prevention unit prevents travel exceeding the cut line for the cut line running on the back surface of the packaging bag of the cut line that travels so as to divide the packaging bag by the opening means. Therefore, the cut line that travels on the back surface of the packaging bag by the opening means does not travel to the first bite portion side beyond the cut line travel prevention portion. In other words, when removing the piece of the first bite part of the packaging bag divided by the cut line, make sure that the fast food part exposed from the remainder left on the fast food side contains the first bite part. Can do. This makes it possible for the food in a bag that is sold in a sealed state to be eaten as it is immediately after opening, enabling the first bite immediately after opening, that is, the FB guarantee immediately after opening the bagged food Can be improved.

  One of the optional aspects of the present invention is that an angle formed between an ideal cut line formed on the packaging bag by the opening means and a side surface of the fast food food facing the start of the cut line is The bag-containing food is characterized in that it has an obtuse angle on the side of the cut line travel prevention portion.

  In this packaged food, the angle between the ideal cut line that travels through the packaging bag by the opening means and the side of the fast food that faces the start of the cut line is an obtuse angle on the first bite side of the packaging bag. The formation position of the unsealing means is selected so as to have an acute angle on the opposite side. For this reason, when the cut line that runs by the opening means starts running from the start to the side of the fast food food, the angle formed with the side of the fast food food is obtuse when it interferes with the fast food food. It becomes easy to travel in a certain direction, that is, the cut line travel blocking portion side. Thereby, it can prevent that the area of the remaining part left on the fast food food side of the packaging bag parted by the cut line reduces, and can prevent the fall of the food grasping ease through the remaining part.

  One of the selective aspects of the present invention is that the first bite portion is either one of the back surface direction of the packaging bag and in the direction substantially orthogonal to the cut line travel prevention portion, rather than substantially half of the packaging bag. The cut line running prevention part is located between approximately half of the packaging bag and the first bite part.

  In this packaged food, in the direction of the back surface of the packaging bag and in the direction substantially perpendicular to the cut line travel prevention portion, the cut line travel prevention portion is located between approximately half of the packaging bag and the first bite portion, The remaining portion left on the fast food side can be secured in a size sufficient for eating with the fast food.

  One of the selective and more specific aspects of the present invention is that the packaging bag is formed by winding a sheet-shaped packaging material around the rice ball in a cylindrical shape, and winding the packaging material. A first welding portion as the cut line travel prevention portion formed by linearly welding ends in the turning direction, and a second welding formed by linearly welding one cylindrical opening of the body portion. A third welded portion formed by linearly welding the other cylindrical opening of the body portion, and the second weld for tearing the body portion from the second welded portion side to the third welded portion side. It is a bag-containing food characterized by having a notch for opening as the opening means provided in a cut shape at the end of the part.

  According to the present invention, the cut line travel blocking portion is provided on the back surface of the packaging bag so as to block between the opening means and the fast bite portion of the fast food food. The cut line travel prevention unit prevents travel exceeding the cut line for the cut line running on the back surface of the packaging bag of the cut line that travels so as to divide the packaging bag by the opening means. Therefore, the cut line that travels on the back surface of the packaging bag by the opening means does not travel to the first bite portion side beyond the cut line travel prevention portion. In other words, when removing the piece of the first bite part of the packaging bag divided by the cut line, make sure that the fast food part exposed from the remainder left on the fast food side contains the first bite part. Can do. This makes it possible for the food in a bag that is sold in a sealed state to be eaten as it is immediately after opening, enabling the first bite immediately after opening, that is, the FB guarantee immediately after opening the bagged food Can be improved.

  In the invention which concerns on Claim 2, the angle | corner which the ideal cut line which drive | works a packaging bag by an opening means, and the side of the fast food food which faces the starting end of a cut line is the first bite part side of a packaging bag The formation position of the opening means is selected so that the obtuse angle becomes an acute angle on the opposite side. For this reason, when the cut line that runs by the opening means starts running from the start to the side of the fast food food, the angle formed with the side of the fast food food is obtuse when it interferes with the fast food food. It becomes easy to travel in a certain direction, that is, the cut line travel blocking portion side. Thereby, it can prevent that the area of the remaining part left on the fast food food side of the packaging bag parted by the cut line reduces, and can prevent the fall of the food grasping ease through the remaining part.

  In the invention which concerns on Claim 3, it is a back surface direction of a packaging bag, and a cut line travel prevention part is located between the substantially half of a packaging bag, and a first bite part in the direction substantially orthogonal to a cut line travel prevention part. Therefore, the remaining part left on the fast food side can be secured in a size sufficient for eating with the fast food.

  In the invention which concerns on Claim 4, the FB guarantee property similar to each invention mentioned above is realizable in concrete packaging bag shape.

It is a front view of a rice ball with a bag. It is a rear view in the state where the quality display label non-adhesion state of a bagged rice ball. It is a rear view in the state where the quality display label sticking state of the rice ball in a bag is affixed. It is a right view of a rice ball with a bag. It is the figure which showed typically the state which fractured | ruptured the bagged rice ball along the AA line. It is a perspective view of a rice ball with a bag. It is a figure which shows the state which opened the rice ball with a bag. It is a figure which shows the modification of a rice ball with a bag.

  In this embodiment, as a packaged food in which fast food food is encapsulated, a description will be given by taking a rice ball with a triangular rice ball sealed in the bag as an example, but the term fast food food used in this embodiment is a so-called The concept is not limited to fast foods sold at fast food restaurants, but can be understood as a concept that includes all foods that can be eaten as if the bag is opened and immediately struck.

  FIG. 1 is a front view of a rice ball 1 in a bag, FIG. 2 is a rear view of the bag rice ball 1 in a state where the quality label is not attached, and FIG. 3 is a state in which the quality indicator label of the bag rice ball 1 is attached. FIG. 4 is a rear view, FIG. 4 is a right side view of the packaged rice ball 1, and FIG. 5 is a diagram schematically showing a state in which the packaged rice ball 1 is broken along the line AA.

  The bag-containing rice ball 1 includes a rice ball 10 that is a content, and a packaging bag 20 that seals the rice ball 10 in an individually packaged state. On the rice ball 1 in the bag, the front 20E of the packaging bag 20 is displayed with characters, designs, patterns, etc. ("salt rice ball" in the figure) representing the product. A quality display label 30 is attached, which indicates a deadline (or expiration date), a manufacturer, and the like. In addition, the sticking position of the quality display label 30 is not restricted to the back surface 20F of the packaging bag 20.

  Here, fast food foods (FF foods) encapsulated foods are eaten so as to directly stick to FF foods, and the first part to be beaten is its shape, opening mouth and It is largely determined by factors such as the positional relationship. In addition, for the size of a person, statistically estimated that a certain size is sufficient on average even if it slightly fluctuates due to differences in mouth size and personal taste preferences Is possible.

  For example, the rice ball 10 that is a triangular rice ball is a part where the vicinity of the apex of the triangle that is generally close to the opening is first struck (hereinafter referred to as “first bite part (FB part 11)”), and the apex. About 1 to 3 cm from the vicinity is considered to be a single size. In addition, FB part can be assumed also in another FF foodstuff. For example, in the case of a round rice ball having a thick disc shape, a circular dome-shaped hamburger or the like, a certain range of a single punch is assumed as the FB portion from the circumferential portion most protruding from the opening of the packaging bag 20, In a substantially elliptical hemispherical hot dog, a certain range from one end (one in the longitudinal direction) of the cut line sandwiching the ingredients is assumed as the FB portion.

  The packaging bag 20 is linearly provided on the back surface 20F side so that the cut line travel prevention portion 21 (CL travel prevention portion 21) crosses the back surface 20F. The CL travel prevention unit 21 prevents travel of a cut line that crosses from one side to the other side with the linear CL travel prevention unit 21 interposed therebetween. The CL travel blocking portion 21 is an end portion of the rice ball 10 near the FB portion 11 (hereinafter referred to as FB) in a direction along the back surface 20F of the packaging bag 20 containing the rice ball 10 and substantially orthogonal to the CL travel blocking portion 21. It is provided at a position near the opposite end portion with the FB portion 11 sandwiched between the side end portion 20A). That is, the FB portion 11 is positioned closer to the grip side end portion 20B than the approximately half of the packaging bag 20, and the CL travel prevention portion 21 is positioned between the approximately half of the packaging bag 20 and the FB portion 11.

  In the following, the end opposite to the FB side end 20A across the rice ball 10 is in a direction substantially parallel to the grip side end 20B, and the back surface 20F of the packaging bag 20 is gripped with the FB side end 20A. One of the end portions in a direction substantially orthogonal to the direction connecting the side end portions 20B is a right end portion 20C, and the other is a left end portion 20D.

  The packaging bag 20 is in a position closer to the gripping side end 20B than the CL travel prevention unit 21 in a state where the rice ball 10 is accommodated in the packaging bag 20, and the FB part 11 and the gripping side end 20B of the rice ball 10. An unsealing means 22 is provided between the side end portion 10B.

  For example, the opening means 22 joins the packaging material constituting the front surface 20E of the packaging bag 20 and the packaging material constituting the back surface 20F in a bonded manner along the right end portion 20C, so that the right end portion of the packaging bag 20 is joined. It can be constituted by a notch for opening which is a V-shaped cutout portion formed in a flange-like portion 23 provided projecting from 20C.

  The shape of the notch for opening is not limited to the V shape, and can be realized in various shapes such as a U shape, a semicircle, a trapezoid, a U shape, a straight shape, an arc shape, and the like. Moreover, the opening means 22 can employ various opening means that do not impair the sealing performance of the opening tape and other packaging bags 20. Further, as shown in FIG. 8, the opening notch may be provided also in the bowl-like portion 24 provided so as to protrude from the left end portion 20 </ b> D of the packaging bag 20.

  When the packaging bag 20 is cut using the opening means 22, the cut line CL travels ideally so as to cross the packaging bag 20 from the right end 20C toward the left end 20D. The packaging bag 20 cut along the cut line CL is divided into two parts, a gripping remaining part 221 near the gripping side end part 20B and a handle exterior 222 near the FB side end part 20A.

  The gripping remaining portion 221 is left as it is while covering a certain range of the rice ball 10 near the end portion 10B facing the gripping side end portion 20B. can do. Thereby, the eating and drinking person can hold the rice ball 10 without directly bringing the finger into contact with the rice ball 10, so that hygiene in eating and drinking can be improved, and contamination of the finger of the eating and drinking person can be prevented.

  On the other hand, the exterior 222 is removed from the rice ball 10 and discarded, but the exterior 222 includes almost all of the CL travel prevention unit 21, and the CL travel inhibition unit 21 is also removed together. It will be. Since the CL travel prevention unit 21 is less easily tearable and less flexible than other parts, the CL travel prevention unit 21 does not remain in the gripping remaining part 221, so that a person can eat and drink via the gripping remaining part 221. When the rice ball 10 is gripped, it can be eaten while directly feeling the surface shape of the rice ball 10 with fingers.

  Further, as will be described later, the CL travel prevention unit 21 usually has a different texture and light transmittance (mostly low transparency) from other parts of the packaging bag 20. For this reason, by not leaving the CL travel prevention part 21 in the gripping remaining part 221, when placing the gripping residual part 221 on the rice ball 10 and placing it on a plate or tray, the aesthetics due to the attachment of the gripping residual part 221 Can be prevented. When the packaging bag 20 is formed of a transparent packaging material, the surface of the internal rice ball 10 can be easily viewed through the gripping remaining portion 221.

  Furthermore, in the packaged rice ball 1 according to the present embodiment, as described above, even if the cut line CL runs away from the ideal cut line toward the FB side end portion 20A, the packaging bag as described above. On the back surface 20F of 20, since the CL travel blocking part 21 is provided between the opening means 22 and the FB part 11 of the rice ball 10, the cut line CL extends to the FB side end 20A beyond the CL travel blocking part 21. Never travel to a close position. That is, the travel range of the cut line CL can be limited to a range closer to the grip side end 20B than the CL travel prevention unit 21.

  Thereby, immediately after opening the packaging bag 20 using the opening means 22, the state which the FB part 11 of the rice ball 10 has exposed reliably outside the holding | maintenance remainder 221 can be ensured. That is, it is possible to improve the initial FB guarantee performance immediately after opening the packaged rice ball 1.

  The formation position of the opening means 22 may be determined in consideration of the shape of the rice ball 10 in the packaging bag 20. That is, the angle formed between the ideal cut line and the side surface of the rice ball 10 on the side surface of the rice ball 10 positioned on the travel line of the ideal cut line that travels the packaging bag 20 by the opening means 22 is the side of the FB side end 20A. The unsealing means 22 is provided in such a positional relationship that the angle is an obtuse angle and the angle on the grip side end 20B side is an acute angle.

  As a result, the cut line CL that travels from the leading end of the cut line CL toward the rice ball 10 is biased to flow toward the FB side end 20A due to interference with the side surface of the rice ball 10. That is, the cut line CL is guided to travel closer to the CL travel prevention unit 21 than the ideal cut line.

  Conversely, since the cut line CL is biased so as not to travel to the grip side end 20B side than the ideal cut line, the remaining amount of the gripping remaining portion 221 formed by being divided by the cut line CL Erosion can be suppressed. Thereby, the grip ease of the rice ball 10 via the grip remainder 221 can be improved.

  Further, the above-described quality display label 30 is attached to a part closer to the FB side end 20 </ b> A than the CL travel prevention part 21 on the back surface 20 </ b> F of the packaging bag 20. Thereby, the CL travel prevention unit 21 is interposed between the quality display label 30 and the cut line CL, and the cut line CL does not interfere with the quality display label 30.

  In addition, when the packaging bag 20 is divided at the cut line CL, the quality display label 30 is also removed from the rice ball 10 at the same time as the removal of the removal part 222 that is a part above the cut line CL. For this reason, prevention of the fall of the aesthetics mentioned above and the visibility of the surface of the rice ball 10 through the holding | maintenance remainder 221 are ensured.

  In this case, for example, when the CL travel prevention part 21 is formed so as to protrude like a bowl from the back surface 20F of the packaging bag 20, the bowl-like CL travel prevention part 21 is bent to the FB side end 20A side to display the quality display label 30. May be attached to the back surface 20F to determine the folding direction of the hook-shaped portion.

  Hereinafter, a more specific example of the bagged rice ball 1 according to the present embodiment will be described.

  The packaging bag is a sheet-shaped packaging material in which a rice ball 10 is placed and wound into a cylindrical shape to form a body portion, and both edge portions in the winding direction are polymerized in a palm-like manner to determine a polymerization portion. The first adhesive part is formed by linearly bonding with the width, and the cylindrical openings on both sides are welded linearly to form the second welded part and the third welded part, and the body part is on the second welded part side It is created by forming a notch for opening provided in a cut shape at the end of the second welded portion so as to be torn to the third welded portion side. In addition, the 1st welding part formed here comprises CL driving | running | working prevention part. The first welded portion is fixed in a bent state by a quality display label 30 that is attached above the first welded portion in a state of being bent upward.

  Thus, the effectiveness of the cut line travel prevention can be improved by configuring the CL travel prevention part with the first adhesive part in which the ends are superposed and bonded in the shape of a palm. In other words, since the separate end portions are joined and bonded together, even if the cutting line reaches the CL travel prevention portion and a cutting force is applied to the CL travel prevention portion, the joined ends are finally joined. Only the part is separated, and the cut line does not travel beyond this.

  The packaging bag can be formed using various packaging materials. The packaging material preferably has a thickness of 30 to 50 μm. For example, a transparent sheet material based on plastic such as polypropylene, or a sheet in which a thermoplastic synthetic resin such as polyethylene is laminated on Japanese paper or pseudo Japanese paper is used. An opaque sheet material as a base material can be used. Characters and patterns can be printed on the packaging material, and product names, company names, various types of pops, and necessary items for food sales are printed.

  The rice ball 10 is placed with a substantially rectangular surface formed along one side of the triangle as a bottom surface 25. For this reason, the packaging bag 20 is provided with a substantially flat bottom surface 25 that contacts the bottom surface 15 of the rice ball 10. The bottom surface 25 is formed with folding portions 26 and 27 which are formed by folding the left and right sides upward in a valley shape.

  For this reason, the bottom surface 25 is formed as a flat surface at the portion that comes into contact with the bottom surface 15 of the rice ball 10. However, in the folding portions 26 and 27 near the left and right end portions, the front and rear widths are gradually narrowed as approaching the left and right end portions. On the other hand, the inclined surfaces 251 and 252 have a triangular shape in plan view that is inclined upward. The remaining folding portions 26 and 27 positioned before and after the inclined surfaces 251 and 252 are triangular folding surfaces 26a, 26b, 27a, and 27b (27a and 27b are illustrated) overlapping the front and back films of the packaging bag 20, respectively. Not shown). By forming the folding portions 26 and 27 in this way, when the rice ball 10 is accommodated so that the bottom surface 15 contacts the bottom surface 25 of the packaging bag 20, the folding portions 26 and 27 have the shape of the bottom surface 25 of the packaging bag 20. The shape of the bottom surface 25 can be maintained by spreading on the left and right sides of the rice ball 10.

  Note that the folding amount of the folding portions 26 and 27 with the bowl-shaped portions 23 and 24 is set to approximately ½ of the thickness of the rice ball 10 in the front-rear direction. Further, by applying a part coat to the surface of the packaging material corresponding to the folding position of the folding parts 26 and 27, the folded packaging material is sandwiched between the hook-like parts 23 and 24 and thermally welded, and the folded polymerization surface The packaging materials are welded to each other so as not to be separated.

  Thereby, the shape maintenance characteristic of the bottom face 25 is improved, and the rigid hook-like parts 23 and 24 are provided upright from both the left and right ends of the bottom face 25 as compared with the packaging material of other parts, The self-supporting property of the bag-containing rice ball 1 when the bottom surface 25 of the packaging bag 20 is placed on the placement surface can be improved.

  Further, the packaging bag 20 is provided with a grip allowance portion 28 where the rice ball 10 is not accommodated between the upper end of the rice ball 10 accommodated therein and the FB side end portion 20A. The size of the grip allowance portion 28 is such that the upper part of the packaging bag 20 can be grasped with a finger without pressing the rice ball 10 and can be set within a range of 25 to 40 mm.

  Thereby, it becomes possible to grip the handle portion 28 without touching the rice ball 10 accommodated in the packaging bag 20 and handle it, and the grip force is applied to the rice ball 10 from the time it is manufactured until it is displayed in the retail store. Handling that is difficult to propagate is possible, and handling is improved.

  Note that the present invention is not limited to the above-described embodiments, and the configurations disclosed in the above-described embodiments are interchanged with each other or the combinations thereof are changed, disclosed in the known technology, and in the above-described embodiments. A configuration in which each configuration is mutually replaced or a combination is changed is also included. Further, the technical scope of the present invention is not limited to the above-described embodiments, but extends to the matters described in the claims and equivalents thereof.
