Japanese Utility Model Registration No. 3078552

  In this conventional example, a pair of gripping pieces that partially protrude from an opening edge of a body portion of a paper container with vertical folds made by drawing and press-molding paper are integrally provided, so that each gripping piece is held with both hands. By holding it, even a paper container with vertical pleats containing hot items can be safely carried to other places, and the single piece of container can be easily separated from the stack of paper containers with many vertical pleats by the gripping piece. On the other hand, since there is no cut at the base of the gripping piece, it is difficult to cut the opening edge of the container body from the base of the gripping piece downward with fingers, and it is evenly adhered to the opening edge of the container body and bulges upward. It is extremely difficult to peel the container body from the processed food in the container, such as a baking cake or steamed confectionery, by hand, and to eat it quickly. Awake or finger above There is an essential and serious problem that the product is easy to touch strongly and dirty hands and is extremely unsanitary.This problem is caused by the rigidity of paper such as plastic laminate paper and plastic film sticking paper. This is particularly noticeable in paper containers.

  This invention makes it easy to cut the container body from the base of the gripping piece by forming a small cut downward at the base of the gripping piece that partially protrudes from the opening edge of the body of the paper container with vertical folds. The purpose is to:

  The purpose of this invention is to form a container body having a large number of vertical folds around the container bottom and to integrally form the container body with a gripping piece that partially projects at the opening edge of the body. This was achieved by forming a small cut downward at the base of the gripping piece in making the paper container of the above.

The present invention employs the above-described means, and has the following effects.
According to the first to third aspects of the present invention, a small cut is formed downward at the base of the gripping piece partially protruding from the opening edge of the body of the paper container with vertical pleats. Even with a paper container with vertical folds made of composite paper with enhanced rigidity such as plastic laminated paper or plastic film sticking paper, hold the outer peripheral surface of the torso with one hand and use the other hand to hold the gripping piece at the base cut. By shredding from the container, the container body can be partially cut and spread from the opening edge of the container body to the container bottom together with the gripping pieces, so that the baking cake that has adhered evenly to the container opening edge and swells upward can be The container body can be easily peeled from the processed food in the container such as steamed confectionery to the bottom of the container with only the fingers together with the gripping piece, and then the peeled edges can be removed with both hands. By picking and spreading outward and downward, even children and elderly people can easily peel off most of the body of the container from the food in the container without soiling their fingers, and display most of the food on the expanded container. It has an excellent effect of letting out and eating hygienically.

  Further, according to the above inventions, in order to separate and use the uppermost container from the stack of paper containers with a number of vertical folds one by one, the cut of the base of the gripping piece is formed downward. Therefore, since the cut does not tear even if the gripping piece is pulled upward, the gripping piece in the uppermost container is pulled upward, so that the gripping piece can be cut from the pile of stacked containers without cutting the gripping piece. There is also an effect that the upper container can be sequentially separated as a single item.

  According to the invention of claim 4 of the present invention, a plurality of the gripping pieces are horizontally protruded in pairs at the opening edge of the container body, so that even a paper container with a vertical pleat containing a hot material can be held in a hand-held state. Since the stability is increased and the paper container with vertical folds can be held in a two-handed pan type, the effect of being more safe and convenient can be added. Further, in the inventions of claims 5 to 8 in the invention, The rigidity of the container as a whole is large because the rigidity of the container as a whole is high because the material of the paper container with vertical folds is made of plastic laminate paper, plastic film sticking paper, silicone resin kneaded paper, or dissolved silicone resin coated paper. As a result, it is possible to prevent the paper container with vertical folds from expanding and deforming when the food dough is heated and expanded and when transporting the container, and to prevent the food inside the container from sticking to the inner surface of the container when heating. As described above, if a perforated cutting line is formed near the bottom of the container at a small distance from the cut of the base of the gripping piece as in the invention of claim 9 of the present invention, Even a paper container with vertical folds made of paper material with enhanced rigidity, the container body can be partially cut from the opening edge of the container body to the container bottom from the opening edge of the container body along with the gripping piece from the perforated cutting line. The effect could be added.

An embodiment of the present invention will be described with reference to the drawings.
The best mode of this invention is to use rigid paper or laminated paper with plastic such as polyethylene terephthalate (PET) or polypropylene (PP). Using a blank 1 as shown in FIG. 2 made of stiffened paper such as paper, a container body 4 having a number of vertical folds 3 around a container bottom 2 as shown in FIGS. Two pairs of gripping pieces 6 are integrally provided at the opening edge 4a.

  That is, the portion to be the gripping piece 6 is formed from the container molding blank 1 having the gripping piece protrusion 6a die-cut toward the corner of the square paper and the small cuts 7 on both sides of the base as shown in FIG. A pair of well-known male and female bevel-gear press-molding dies partially protrude from an opening edge 4a of a container body 4 having a large number of vertical folds 3 around the container bottom 2 as shown in FIGS. Four pairs of gripping pieces 6 are integrally protruded, and small cuts 7 are formed on one side or both sides of the base of at least one of the gripping pieces 6 or all the gripping pieces 6, respectively. The paper container 5 with vertical folds according to the present invention was obtained by forming it downward as shown in FIG.

  Therefore, when using the paper container 5 with vertical folds according to the present invention, the container has a large rigidity made of rigidity-reinforced composite paper such as plastic laminated paper or plastic film sticking paper or rigidity-reinforced paper such as silicone resin kneaded paper. Even in the case of a paper container with vertical pleats, the outer peripheral surface of the body 4 is held with one hand, and the gripping piece 6 is pulled down or diagonally from the cut 7 of the base 6A with the other finger to lower the container body 4. As shown in FIG. 1, the gripping piece 6 is further shredded from the opening edge 4 a to the container bottom 2 together with the gripping piece 6, and is evenly adhered to the opening edge 4 a of the container body to bulge upward. As shown in FIG. 1, the container body 4 can be easily peeled off from the processed food in the container with only fingers, and then the upper part of each peeled edge 4b is further moved with both hands. As shown in the arrow of FIG. 1, a large part of the container body 4 can be easily peeled off from the processed food in the container without soiling the fingers even by children and elderly people. In addition, most of the processed food is exposed on the upper surface of the spread paper container 5 with vertical folds, so that it can be eaten hygienically.

  Further, in order to sequentially separate and use the uppermost container 5 from a stack of paper containers with a number of vertical folds and to use them separately, since the cut 7 of the base 6A of the gripping piece 6 is formed downward, Since the cuts 7 do not tear even when the gripping pieces 6 are pulled upward, the gripping pieces 6 of the uppermost container 5 are pulled upward, so that a large number of stacked containers can be formed without cutting the gripping pieces 6. , The uppermost container 5 can be sequentially separated as a single item.

  The planar shape of the bottom plate 1 in the present invention is not limited to a circle as shown in each drawing, but may be an ellipse, a polygon such as a square or a hexagon, and the gripping piece 6 in the container of the present invention is as shown in FIG. May be bent laterally to form a horizontal gripping piece 6, and a notch 7 may be formed at the bent base. Further, the notch 7 does not need to be formed at the entire base of each gripping piece 6. By simply forming a cut 7 in at least one of the bases of the base 6, the container body 4 can be cut downward from this cut 7, or separated from the cut 7 of the gripping piece base by a small distance. If a perforated cutting line m is formed near the bottom of the container as shown in FIG. The part of the container body with the gripping piece It can be extended shredded from the rim to the bottom of the vessel.

  In addition, the paper sheet that makes the paper container with vertical folds according to the present invention may be plain paper, but there is no problem with food hygiene such as plastic laminated paper, plastic film sticking paper, silicone resin kneaded paper, dissolved silicone resin coated paper, etc. If a paper material with enhanced rigidity is used, the rigidity of the whole container will be large, so that the paper container with vertical folds can be prevented from expanding and deforming when the food dough is heated and expanded or when the container is transported, and inside the container. Corrosion to the inner surface of the container when heating the food can be prevented.

  The paper container with vertical folds according to the present invention can also be used as a paper container for frozen confectionery.
