Description

  The present invention relates to a food packaging bag for packaging foods such as sandwiches and castellas (hereinafter referred to as “sandwiches”) with a packaging film. The present invention relates to a food packaging bag.

  Various food packaging bags have been provided in which sandwiches with right-sided triangles are wrapped with a packaging film. For example, Patent Document 1 describes a food packaging bag (hereinafter referred to as a “packaging bag”) that can accurately tear a packaging film.

  That is, as shown in FIG. 5, this packaging bag seals both side edges 11 and 21 of the overlapped trapezoidal front film 10 and trapezoidal back film 20, and has narrow ends (hereinafter referred to as "upper ends"). It is said that the sealing portion 54 is provided by sealing the vicinity of the portion in a band shape between both side edges 11 and 21 of the front and back films 10 and 20. In this packaging bag, the upper side of the sealing part 54 is a header part 51, and the upper edge of the header part 51 is also sealed. In addition, although the header part 51 illustrated is formed in a rectangular shape, there is a type formed in a trapezoidal shape.

  In addition, the other end (hereinafter referred to as “lower end”) of the packaging bag is not sealed, and is an opening 52. The packaging bag is provided with a storage portion 53 for storing the sandwich S (see FIG. 6) inside the sealing portion 54, the side edges 11, 21, and the opening 52. Further, on the inner side surface of the front film 10, an antifouling film (not shown) for overlapping the stored sandwich S so as not to become dirty even if it is rubbed is overlaid.

  In this packaging bag, a cut line 21 serving as an unsealing start point is formed at the center of the storage portion 53 in the back film 20. The cut line 21 is formed in an inverted U-shape as shown in the figure by a cut line, a perforation, or the like, and the inside of the inverted U-shaped cut line 21 is a knob 22.

  And the cover film 40 which covers the cutting line 21 is piled up on the inner surface of the back film 20 which the inside and outside communicated by the cutting line 21, and the back film 20 and the cover film 40 so as to surround the cutting line 21 Is sealed and an isolation 56 is provided. The cover film 40 is formed to have the same length as the width of the front and back films 10 and 20, and both end edges are sealed to the side edges of the front and back films 10 and 20.

  The back film 20 is provided with cutting means 31 from the vicinity of the cut line 21 toward the opening 52. The cutting means 31 is generally composed of a cut tape attached to the back surface of the back film 20.

  Then, the air is blown into the opening portion 52 so that the opening portion 52 is opened in a rectangular shape, the sandwich S is stored in the storage portion 53, and the front and back films 10, 20 on the opening portion 52 side are opened. The bottom surface portion D is provided by folding (see FIG. 6), and the bottom surface portion D is sealed with a product information label (thermal label) (not shown), so that the sandwich S is packaged.

  The sandwich S is maintained at the desired quality because the outside air does not enter the storage portion 53 from the cut line 21 by the isolation portion 56. In addition, since a merchandise information label is affixed on both the front and back films 10 and 20 which were folded and overlapped, a wrinkle arises in a merchandise information label and it becomes difficult to see described merchandise information.

  And in order to eat the packaged sandwich S, as shown in FIG. 6, the knob 22 provided inside the cut line 21 is picked and pulled in the bottom surface D direction. Then, the cut line 21 becomes an opening start point, the back film 20 is guided by the cutting means 31 and is torn from the cut line 21 toward the bottom surface portion D, and the packaging bag is opened. Therefore, the packaged sandwich S can be taken out from the storage portion 53 and eaten.

JP 2009-40430 A

  In the packaging bag that wraps the sandwich S including the packaging bag described in Patent Document 1, a product name, a design, and the like are printed on the front side of the header portion 51. Since the front and back films 10 and 20 constituting the header portion 51 are manufactured from a transparent film, the header portion 51 and the like are subjected to white plate printing (solid white) prior to printing of a design or the like. .

  However, white plate printing becomes translucent when exposed to light, and the design is unclear. For this reason, there is a request for white plate printing twice. However, performing the white plate printing twice not only takes time, but also contributes to an increase in cost.

  Moreover, since the header part 51 protrudes upwards from the storage part 53 which accommodated the sandwich S, it is easy to bend. When the header 51 is bent, the product name and the like are difficult to see and the appearance is impaired.

  Then, this invention makes it a subject to provide the packaging bag for foods which made the header part have a waist while clearing printing of the design etc. of a header part.

The packaging bag for food according to the present invention seals both side edges of two overlapped packaging films and seals the vicinity of one edge of the two packaging films between both side edges to provide a sealing portion. By providing a header portion between one end edge of the two packaging films and the sealing portion, and making the other end edge of the two packaging films into an opening portion without sealing, the opening portion And a packaging bag for food provided with an inner side surrounded by both side edges of the two packaging films and the sealing portion, and a cut line as an opening start point is sealed in the inner side of the one packaging film. is formed in the vicinity of stop portion, an opaque sheet comprising a opening means are overlaid so as to cover the header part and the cut lines provided by one of the packaging fill arm said, the one of the opening side than the least score lines opaque sheet and the packaging film of It is characterized in that door and is attached strongly impossible to peel.

According to this food packaging bag, the opaque sheet is overlapped so as to close the header portion and the cut line provided by one of the packaging films, so that the opaque sheet acts like white plate printing, In addition to clear printing of designs and the like, it is possible to keep the header portion bent so that the header portion is not easily bent. And if an opaque sheet | seat is picked and it pulls toward the opening part, one packaging film will be torn from a score line and can be opened. Furthermore, by forming the score line in the vicinity of the sealing portion in the storage portion of one packaging film, the one packaging film is torn toward the opening portion without being broken in the sealing portion.

Furthermore, in food packaging bag according to the present invention, the opaque sheet, which is preferably releasably weakly stuck with the one of the packaging film of the header portion than score line. According to this packaging bag for food, the header part and the opaque sheet are united by attaching one of the packaging films closer to the header part than the score line and the opaque sheet so as to be peeled weakly. The part has a lower waist and is less likely to bend. Further, the opaque sheet is peelable and weakly attached to one of the packaging films, so that it can be peeled off from the header part at the time of opening.

  In the food packaging bag according to the present invention, the opaque sheet is preferably a product information display label. According to this food packaging bag, the product information label that has been conventionally affixed to the bottom part is affixed flat to the header part, so that the product information can be easily viewed.

  Moreover, in the food packaging bag according to the present invention, it is preferable that the cut line is formed to have a width substantially the same as the width of the header portion. According to the packaging bag for food, since the cut line is formed wide, one of the packaging films is torn wide from the cut line, and the food in the storage portion can be easily taken out. The opaque sheet has a width substantially the same as the width of the header portion, so that it cuts off the wide cut line.

  ADVANTAGE OF THE INVENTION According to this invention, the packaging bag for foods which overlapped and stuck on one packaging film so that an opaque sheet | seat might block | close a header part and a cut line can be provided. In this food packaging bag, even if the white printing is not performed twice, the printing of the design and the like becomes clear, and the header portion has a waist and does not bend.

It is a front view which shows an example of the conventional food packaging bag. It is a perspective view which shows an example of the conventional food packaging bag.

  An embodiment of a food packaging bag (hereinafter referred to as “packaging bag”) according to the present invention will be described with reference to FIGS. Note that portions corresponding to those of the conventional art are described with the same reference numerals.

In this packaging bag, the cut line 21 is formed in the vicinity of the sealing portion 54 in the storage portion 53 of one packaging film (“back film” in the embodiment) 20. The cut line 21 is formed to be as wide as the width of the header portion 51 as in the first embodiment shown in FIGS. 1 and 2 and as in the second embodiment shown in FIG. or it is formed to narrow as in the third embodiment shown in FIG.

  In any case, since the cut line 21 is a starting point for tearing the back film 20, it is preferably formed in an inverted U shape with the tip portion facing the opening 52 as illustrated. However, the cut line 21 may be a semicircular shape, an inverted V shape, an X shape, a negative shape, or the like (not shown).

  Then, two openings 52 are provided from the respective leading end portions of the cut line 21 toward the opening portions 52 (shown only in FIG. 1 of the first embodiment, but the second and third embodiments are also provided). Opening assisting means 32, 32 are provided. The interval between the two opening means 32, 32 is as large as the width of the header portion 51 in the first and second embodiments, and is narrowed in the third embodiment.

  Each opening assisting means 32 is preferably formed by half-cutting. This half cut may be formed by the cutting auxiliary line forming method of Japanese Patent No. 4264123 obtained by the present applicant. This half-cut has a shape in which protruding ridges are formed on both sides of a deep groove-shaped cutting auxiliary line, and the opening 52 (bottom part) extends from the tip of the cutting line 21 without deviating from the cutting auxiliary line by the protruding part. D) is torn along the auxiliary cutting line.

  And this packaging bag is affixed on the back film 20 so that the opaque sheet 60 may block the header part 51 and the cut line 21. When the header portion 51 has a quadrangular shape as illustrated, the sheet 60 is also formed in a quadrangular shape. When the header portion 51 has a trapezoidal shape (not shown), the sheet 60 is formed in a trapezoidal shape in a portion overlapping the header portion 51 and in a square shape in a portion closing the cut line 21.

  And it is preferable that the sheet | seat 60 is colored white. The white sheet 60 meets the conventional request to perform white plate printing twice. That is, the header portion 51 is applied to the header portion 51 in cooperation with the single white plate printing because the white sheet 60 whitens the background of the header portion 51 even if the white plate printing is performed only once. The product name and design are clearly printed on the sheet 60.

  Depending on the product name, the color of the design, etc., the white sheet 60 may be simply pasted to the header portion 51 without performing the white plate printing once.

  The sheet 60 is preferably a product information label. The merchandise information is various useful information about the merchandise such as the date of manufacture, raw materials, seller's name and address, etc., but the merchandise information is described on the sheet 60 and attached to the back film 20 of the header portion 51. Therefore, it can be displayed flat and easy to see.

  Then, the back surface of the sheet 60 has adhesive strength and is attached to the back film 20. However, the sheet 60 is strongly stuck to the opening film 52 side of the cut line 21, specifically, the inner back film 20 surrounded by the inverted U-shaped cut line 21 so as not to be peeled off. The back film 20 on the header section 51 side and the back film 20 constituting the header section 51 are weakly attached so as to be peelable. Moreover, the non-sticking part 61 which does not have adhesive force is provided in the upper end part of the sheet | seat 60, and it is set as a knob | pick part. However, the upper end of the sheet 60 may be a knob having a weak adhesive strength that can be peeled off.

  Further, as shown in FIGS. 1 and 2, the sheet 60 of the first embodiment is overlaid on the entire surface of the header portion 51 and further protrudes from the upper end edge. As shown in FIGS. 3 and 4, the sheet 60 of the second and third embodiments is superimposed on almost the entire surface of the header portion 51 and does not protrude from the upper end edge of the header portion 51. In any case, the header part 51 has a waist by the sheet 60 being pasted from the part where the cut line 21 of the back film 20 is formed to the header part 51 beyond the sealing part 54, and the header part 51 becomes difficult to bend.

  However, the sheet 60 may be attached to the back film 20 only at the portion where the cut line 21 is formed. This is because the sheet 60 affixed to the back film 20 only at the part where the cut line 21 is formed functions as an opening means. Even if the sheet 60 is not affixed to the header part 51, the header 60 is only along the header part 51. The part 51 can be made difficult to bend toward the sheet 60.

  Needless to say, in this packaging bag, the opening 52 provided on the lower end side is opened in a rectangular shape in a state where the front film 10 and the back film 20 are overlapped with each other. Is stored, and both the front and back films on the opening 52 side are folded to provide a bottom surface portion D, and the bottom surface portion D is sealed, so that FIG. 2 (a), FIG. 3 (a), FIG. ), The sandwich S is packaged.

  If the sheet 60 describes product information, the bottom of the packaging bag can be sealed with a transparent tape. Moreover, the sheet | seat 60 which described merchandise information is piled up so that the header part 51 and the cut line 21 of the back film 20 may be block | closed, and it is made a flat state, product information is easy to see, and also the header part 51 Of course, the header 51 has a waist and is not easily bent even if it is not affixed weakly.

  And in order to eat the packaged sandwich S, as shown in FIG. 2 (b), FIG. 3 (b), and FIG. 4 (b), the non-sticking part 61 that is the picking part of the sheet 60 is picked. Pull towards the bottom. Then, the sheet 60 weakly stuck to the header part 51 is peeled off from the header part 51, and the back film 20 on the opening side is pulled to the sheet 60 from the score line 21 strongly stuck to the sheet 60, so that the score line 21 Is torn with the opening base. Since the cut line 21 is formed not in the header portion 51 but in the storage portion 53 and the back film 20 is torn without passing through the sealing portion 54, the tear film 21 is not broken in the middle of tearing.

  And if the non-sticking part 61 which is a knob | pick part is further pulled down toward the bottom part, the back film 20 will tear along the opening assistance means 32. FIG. For example, as shown in FIG. 2B and FIG. 3B, when the interval between the two opening assisting means 32 and 32 is formed to be substantially the same as the width of the header portion 51, it is cleaved wide. . Moreover, if the space | interval of the two opening assistance means 32 is formed narrowly, it will cleave to a narrow. In any case, the back film 20 can be eaten by taking out the stored sandwich S by cleaving to the bottom by the opening assisting means 32.

  Note that the present invention can be variously modified without being limited to the above embodiment. For example, the opening assisting means 32 may be provided by a general cut tape instead of half cut, or may be provided separately by using a uniaxially stretched film for the back film 20. Further, the sheet 60 may protrude from the upper edge of the header portion 51 as shown in FIG. 1 even if the cut line 21 is narrow as shown in FIG.

  Further, the score line 21 may be formed on the front film 10, and the sheet 60 may be superimposed on the header portion 51 of the front film 10. Moreover, the packaging bag can package not only the sandwich S having a right-sided triangular shape but also foods of various shapes such as a rectangular sandwich S and castella.
