Description

  The present invention relates to a packaging box for storing sandwiches for sale.

Triangular sandwiches made by cutting square breads at an angle are sold in stores after being packaged in film etc. by mechanical or manual work for food hygiene purposes, etc., but soft sandwiches are deformed together with thin films. Therefore, there is a problem in the appearance as a product. Further, there is a drawback that moisture is spilled inside the package, and the sandwich sucks the dew condensation water generated on the film surface and the texture is lowered.
On the other hand, paper-made sandwich packaging boxes have been proposed, for example, as in Patent Document 1 below, which makes it easy to dispose of waste by using paper, and Patent Document 2 in which high-quality feeling and easy removal of the sandwich are facilitated.

JP 2004-196323 A JP 2005-126127 A JP 2006-131271 A

When paper is used as in Patent Documents 1 and 2 above, the shape of the soft and easily deformable sandwich can be maintained so that it does not collapse, which is superior to film packaging in that the appearance of the product due to deformation is not lost.
However, in the packaging box of Patent Document 1, when the lid is opened and pulled out, the box is deformed and the lid is difficult to open, and the fingers are forcibly inserted into the narrow gaps on both sides of the box to grip the sandwich. In addition, the sandwich must be pulled out, and it is difficult to remove the sandwich. Moreover, since the box of patent document 2 must remove the label which closed the cover plate of the rear surface, and then open the cover plate to take out the sandwich, the take-out operation is troublesome and cannot be quickly taken out.
A bag for sandwich packaging, which is made of film, not paper, but has two perforated cuts for taking out the sandwich, has been proposed. The sandwich can be taken out by tearing it into a film, but since it is wrapped with a film, the film is deformed and stuck to the sandwich, making it difficult to remove, and the moisture contained in the ingredients on the surface of the film causes condensation water. Occurs, and the quality of the sandwich is lowered by sucking the water.

  The present invention has been made in view of the above circumstances, and can preserve the appearance of the sandwich without deteriorating the quality of the product when stored, and can be easily taken out of the box when eating. The purpose is to provide a packaging box.

  In order to solve the above-mentioned problems, the sandwich packaging box of the present invention is a paper having a shape-retaining property, and has a rectangular front part that rises obliquely in the backward direction, and hangs from the upper side of the front part with the same width as the front part. Each of the right and left sides of the front part, the back part and the bottom part. Forming a box composed of a side face of a right triangle surrounded by a side, from the front boundary side of the bottom surface of the box to the upper side of the back surface through the boundary side behind the bottom surface, A hook-in insertion tongue piece for forming a linear zipper-type perforation that separates the bottom surface portion and the back surface portion on both sides and is connected to the upper side of the back surface of the box so as to straddle the broken end portion of the perforation. It is characterized by projecting.

  According to a second aspect of the present invention, in the above-mentioned device, a front window of the box body is provided with a viewing window that opens obliquely from the bottom toward the other side from the one side to the front. A transparent or translucent film is stretched.

  The invention according to claim 3 is the above-mentioned invention, wherein the viewing window has a minimum width in which all kinds of ingredients of the sandwich can be seen in the lateral direction, and an exposed part of the ingredients in the lower part of the sandwich can be seen in the longitudinal direction. The material exposed portion at the upper part of the sandwich is opened obliquely from the one side part to the upper part on the other side part side so as to be visible.

In the present invention as described above, since the box body is made of paper having shape retaining property, it is possible to carry out over-the-counter sales while maintaining the quality without deforming the sandwich housed therein.
Moreover, during storage, the paper material is covered to prevent excessive drying of the bread and ingredients, and at the same time, the moisture absorption action of the paper material does not generate condensed water in the box.
When eating, a zipper-type perforation can be easily and quickly broken to break the box surface, and the box is greatly opened, and the sandwich can be lightly picked and easily taken out. At that time, the break end portion of the perforation is separated from the box body, but the box body itself is connected to the upper side of the back portion by the hooking tongue piece for hooking over the break end portion. The opening can be greatly opened without collapsing. For this reason, it becomes possible to take out the sandwich neatly without causing the sandwich to collapse.

  In the invention according to claim 2, the shape retaining property of the front portion of the box body is maintained by the remaining surface on the corner side opposite to the front portion, and the sandwich sandwiched through the film from the viewing window It becomes possible to confirm the shape and amount of ingredients.

  In the device according to claim 3, all the ingredients are confirmed by the lateral spread while the observation window is a small area. Since the amount of ingredients can be confirmed, it will be possible to estimate the type and quantity of sandwich ingredients from now on, so that the product can be purchased with peace of mind.

(A) of the present invention is a perspective view seen from diagonally above, and (b) is a perspective view seen from diagonally below. It is a top view which shows the expansion | deployment state before the assembly of a box. It is a perspective view which shows the state which put the sandwich.

An embodiment of the present invention will be described below with reference to the drawings.
The sandwich packaging box of the present invention forms a box of a size capable of storing a sandwich with paper having a shape retaining property such as cardboard.
The paper material has hygroscopicity and water absorption, and if the surface thereof is smooth and the back surface is rough, various designs can be printed and painted on the surface. As the paper material, it is possible to use laminated paper in which resin films are laminated.
As shown in FIGS. 1A and 1B, the box body hangs down with a square front part 1a rising obliquely in the rearward direction and the same width as the front part 1a from the upper side of the front part 1a. A rectangular back surface portion 1b, a horizontal rectangular bottom surface portion 1e between a lower boundary side 1f of the front surface portion 1a and a lower boundary edge 1h of the back surface portion 1b, the front surface portion 1a, the back surface portion 1b, and Side surface portions 1c and 1d of right triangles surrounded by the left and right sides of the bottom surface portion 1e are provided.
As shown in FIG. 1, the side surface portions 1c and 1d are formed in a right triangle that matches a sandwich shape obtained by obliquely cutting a square bread.

Then, the bottom surface portion 1e and the back surface portion 1b passing from the front boundary side 1f of the bottom surface portion 1e of the box 1 to the upper side 1g of the back surface portion 1b through the boundary side 1h on the back side of the bottom surface portion 1e are arranged on both sides. A linear zipper type perforation 2 to be separated is formed.
The zipper-type perforation 2 is provided with two parallel broken line-like cuts 2b, and the broken band surface 2a between the cuts 2b is pulled up from one side to break continuously between the cuts 2b. The band surface 2a is removed so that the paper surface is torn to both sides.
As shown in FIG. 1B, the perforation 2 has one side of two parallel cuts bent inward halfway, so that the inside between the cuts 2b is pulled up from the parallel side to the bent side. Then, the paper surface becomes a fractured band surface 2a having both continuous and regular sides that do not cause irregular fracture to the outside, and a blank space is generated and is torn on both sides.
If the perforation 2 is formed so as to pass through the center of the bottom surface portion 1e and the back surface portion 1b of the box body 1, the surface is divided into two equal parts, so that it is preferable to balance both sides when opening the fracture band surface 2a.

And the tongue piece 3 for the pinching connected to the fracture | rupture belt | band | zone surface 2a is formed in the fracture | rupture start part of the said perforation 2, ie, the lower boundary edge 1f of the front part 1a.
The tongue piece 3 is cut open on the front side and the left and right side surfaces, and connected so that the rear side is integrated with the fracture band surface 2a.
Further, the breaking end portion of the perforation 2 is provided so as to be separated from the box 1 at the upper side 1g of the back surface portion 1b, and the latching insertion tongue is connected to the upper side 1g of the back surface portion 1b so as to straddle the breaking end portion. A piece 6a is projected.
The tongue piece 3 can be easily lifted outward from the front end. And when this tongue piece 3 is picked by a finger and pulled outward, the paper breaks like a band as a broken band surface 2a having regular both sides, and the broken part 9 advances backward, and further the bottom surface part It passes through the boundary side 1h of 1e, bends up, competes with the back surface portion 1b, reaches the top side 1g, is cut, and is separated from the back surface portion 1b.
At this time, the upper side 1g of the back surface part 1b is broken, but the hooking tongue piece 6a provided so as to straddle the part is maintained without separating the upper side 1g of the back surface part 1b.
That is, the bottom surface portion 1e and the back surface portion 1b are wide open so as to divide the box 1 left and right at the breaking portion 9, and the front boundary side 1f of the broken bottom surface portion 1e is connected without being separated at the front surface portion 1a. Since the upper side 1g of the back surface portion 1b is connected without being separated by the hooking tongue piece 6a for latching, the box 1 is greatly opened to the left and right so as to open the hinge.
Therefore, the box 1 itself is not collapsed, and the opening is closed to the original state even if it is opened once.
For this reason, not only can the sandwich S in the inside be easily taken out, but the sandwich that has been eaten can be temporarily returned to the box.

  Further, as shown in FIG. 1 (a), the front portion 1a can be provided with a viewing window 4 for viewing the sandwich inside. A transparent or translucent film 5 is stretched on the viewing window 4 and the opening is sealed with the film 5 to prevent dust and germs from entering inside.

As shown in FIG. 3, the viewing window 4 is opened obliquely from bottom to top from one side of the front portion 1 a of the box 1 toward the other side.
With this oblique opening, an area for maintaining the shape-retaining property of the front portion 1a of the box body 1 is secured on the remaining surface on the corner side, while the film 5 is seen through the viewing window 4 and a part of the inside It is possible to grasp the outline of the sandwich S by visually checking the shape and amount of the ingredients of the sandwich S and estimating other parts.

At that time, for example, the horizontal direction is the minimum width at which all kinds of ingredients of the sandwich S can be seen, and the vertical direction is the ingredient at the top of the sandwich S from one side where the exposed part of the ingredient at the bottom of the sandwich S can be seen. It is possible to open the material exposed portion obliquely to the upper part on the other side portion side where the material exposed portion can be seen.
In this case, it is not a large window where all can be seen, but a small area where a part of the area for maintaining the shape retaining property of the front part 1a of the box 1 can be secured with the remaining surface on the corner side is not visible. Although it is a window 4, since all the ingredients can be confirmed by the spread of the front part 1a in the horizontal direction, the amount of ingredients up to the lower part on one side and the upper part of the other side can be confirmed in the vertical direction. Since it becomes possible to estimate the whole kind and amount of the ingredients of the sandwich S, it becomes possible to purchase the product more safely.
FIG. 3 shows an aspect in which the outer shape of the viewing window 4 is formed in a parallelogram shape having sides 4a and 4b parallel to the sides of the side portions 1c and 1d and having the upper and lower sides 4c and 4d inclined. .

Further, as shown in FIG. 2, the box 1 can be assembled by removing the periphery of one development view and bending it.
The developed view of FIG. 2 is a mode in which the front surface portion 1a and the back surface portion 1b are integrally connected with the bottom surface portion 1e sandwiched therebetween, and the side portions 1c, 1d and the back surface portion 1b are folded on the narrow lines. By inserting the hook insertion tongue piece 6 projecting from the tongue portion insertion slit 7 provided at the base portion of each connecting margin 8 provided at the valley fold portion of the front surface portion 1a and the side surface portions 1c, 1d. The box shape is maintained by the frictional resistance of both, and the pentahedron box 1 shown in FIG. 1 is assembled.

  As for the method of taking out the sandwich from the box 1 with the perforation 2 broken according to the present invention, there is a method of opening both sides with an opening with both hands, but holding the side with the thumb and middle finger with one hand, and the front with the index finger It is also possible to push the part 1a to open the opening part and take it out with another hand.

  The present invention is a paper packaging box for sandwiches, but it can also be used as a sandwich food packaging box.
