Description

  The present invention belongs to the technical field of a composite container in which powder such as powdered milk is stored in a plastic case together with a bag so that the internal powder can be used. Specifically, the bag containing the powder is opened. This relates to a composite container that can be replaced with a bag.

  Conventionally, powders such as powdered milk have been sold in stores in sealed and sealed cans. Recently, powders are packed in bags without using expensive cans as containers. There is known a composite container which is a replacement package and is set in a plastic case in an opened state. In this type of composite container, the opening of the stored bag is held in an expanded state to facilitate the operation of scooping with a lightweight spoon or the like, and to prevent the contents from entering between the bag and the case ( For example, see Patent Documents 1 and 2).

JP 2014-198579 A JP 2014-208540 A

  The composite container described in the cited documents 1 and 2 includes a mouth frame body that is fitted and fixed to the opening edge of the case body, and the mouth frame body is provided with a plurality of pressing pieces that can be rotated or pressed and deformed. These holding pieces hold the opening upper end of the opened bag between the side peripheral walls of the case main body, thereby holding the replacement package in the case main body with the upper end largely open. It is like that.

  However, in such a composite container, since it is necessary to manually operate a plurality of holding pieces, it is not easy to set the opened bag on the case body. Further, when the bag is put into the case body and fixed, especially in the case of a gusset bag which is frequently used at present, the case is often reopened because the opening portion is blocked by the habit of the film. In that case, it is necessary to hold the opening of the bag by hand so that the hand touches the inner surface of the bag, especially in the case of foods whose contents are put into the mouth such as powdered milk, which is not preferable from a hygienic aspect. . In addition, since the holding piece is located inside the case body, the size of the bag that enters is reduced accordingly, so the amount of contents is less than the appearance of the case, and it feels that it will not be used quickly when used. May be disappointed.

  The present invention has been made in view of the above-described problems, and the object of the present invention is to facilitate the operation of storing the powder-containing bag in the case body and to the inside of the bag. It is an object of the present invention to provide a composite container that can be set in a hygienic state without touching a finger and that the inner volume of the bag is not less than it looks.

The composite container of the present invention is a composite container comprising a replacement package formed by filling powder and a plastic case in which the replacement package is stored,
The replacement package is composed of a bag filled with powder and a paper carton for storing the bag. The bag is a type that is opened by forming an opening in the upper part, and the paper carton has a flange facing the upper part. Each flange has a handle portion, the inner surface of the paper carton flange is bonded to the outer surface of the top of the bag,
The case includes a case main body in which a replacement package is placed, a middle frame that is fitted and fixed to an opening edge of the case main body, and a lid body that opens and closes the case main body to which the middle frame is attached. When the opened replacement package is stored, it has a locking part for fixing the handle part of the paper carton with the upper part of the bag open,
A gusset bag is used as the bag of the replacement package, and the bag is held in a paper carton with the short side with the fold folded in advance, and the perimeter of the opening is extended by the amount of the fold. Thus, the dimension is set to be equal to or greater than the circumferential length of the opening of the case body.

  This composite container is opened by opening the paper carton of the replacement package, and then opening the exposed bag by cutting the upper part of the exposed bag, and the replacement container is placed in the case body in the opened state. . Next, hold the handle part on the opposite flange of the paper carton with your hand to widen the opening of the bag, and fix both handle parts to the locking part of the case body to set the replacement package on the case body . At this time, since the handle portion of the paper carton is held and operated, the opening portion of the bag is not held by hand. In addition, the bag of the replacement package extends the perimeter of the opening by the amount of folding, and the opening is sandwiched between the opening edge of the case body and the inner frame, so it is necessary to forcibly widen the opening. There is no.

  The composite container of the present invention opens the paper carton of the replacement package, puts it in the case body with the opening formed in the upper part of the bag, and then holds the handle portion on the opposite flange of the paper carton by hand. Since the replacement container is set in the case by fixing both the handle parts to the locking part of the case body, the replacement container can be easily stored in the case. Since it does not have an opening part by hand and a finger does not touch the inner surface of the bag, it can be set in a sanitary state. In addition, since there is no pivotable or pressure-deformable holding piece for fixing the opening portion of the spread bag, there is no need to reduce the size of the replacement packaging body, and the bag content is less than it looks It can be avoided.

  In addition, the composite container of the present invention uses a gusset bag as a bag of the replacement package, and uses the folding on the short side to set the circumference of the opening of the bag to the circumference of the opening of the case body. By setting as described above, the opening of the bag can be sandwiched between the opening edge of the case body and the inner frame without forcibly widening the opening of the opened bag. The storage work to the main body can be done easily.

And a lid 23 for carrying out the operation. The case main body 21 is provided with a protruding piece-like locking portion 21x at an opposite position inside the opening edge portion 21a.

  The paper carton 10 of the replacement package W is produced by assembling a blank having an unfolded shape shown in FIG. 2, and the bag P shown in FIG. 3 is accommodated in the paper carton 10 in the course of assembling this blank. The

  The blank of FIG. 2 is a case where a paperboard is punched out. As shown in the drawing, a narrow side plate 11, a wide side plate 12, a narrow side plate 13, a wide side plate 14, and a glue margin piece 14a are arranged in this order in the horizontal direction. It is connected continuously. A bottom piece 15 is connected to the lower sides of the narrow side plates 11 and 13, a bottom plate 16 is connected to the lower sides of the wide side plates 12 and 14, and a cover plate 17 is connected to the upper sides of the narrow side plates 11 and 13, respectively. A flange 18 is connected to each of the upper sides of the wide side plates 12 and 14, and a trapezoidal handle portion 18 a is provided on the flange 18.

  The two lid plates 17 connected to the upper sides of the narrow side plates 11 and 13 are overlapped with each other at the time of assembly, and each has a zipper α for opening, which is the lower side at the time of assembly. A plurality of half-cut ruled lines a are formed on the front side of the lid plate 17 in order to increase the adhesive force. In addition, a U-shaped cut line β is formed at the boundary between the flange 18 and the handle portion 18a continuously provided on the upper sides of the wide side plates 12 and 14 so that an elongated hole is formed toward the handle portion 18a when bent. Is formed.

  The bag P in FIG. 3 is a gusset bag whose size of the body portion 1 can be accommodated in a paper carton 10 and is sealed by forming a seal portion 2 by folding the upper portion into a chevron shape with powder filled therein. ing. And the bag P of FIG. 3 is opened by excising the seal part 2 at the cut line 3.

  The procedure for housing the bag P of FIG. 3 and forming the replacement package W in the course of assembling the blank of FIG. 2 is as follows.

  First, in a state in which the adhesive piece 16a of the bottom plate 16 is folded, the bottom plate 16 and the bottom piece 15 are folded inside, the back side of the adhesive piece 16a is bonded to the front side of the bottom piece 15, and the adhesive margin piece 14a is attached to the narrow side plate 11. Folds in the sack pasted state by sticking to the inner surface of the end. When the folded blank is raised, the bottom plate 16 is automatically locked to form the bottom of the carton.

  After forming the bottom by unfolding the folded blank in this way, after putting the bag P from the top as shown in FIG. 4, flatten the chevron part exposed at the top, The flanges 18 are overlapped and bonded by hot melt or the like. That is, the inner side surface of the flange 18 is bonded to the outer side surface of the portion that becomes the opening edge of the bag P. In this case, the entire surface of the flange 18 may be bonded, or may be bonded at several points or linearly bonded in the lateral direction. In short, it is bonded so that the opening of the bag P opens in a square shape when the flange 18 is pulled. Subsequently, the upper part of the paper carton 10 is closed by overlapping and gluing both the cover plates 17. At this time, the cover plate 17 having the half-cut ruled line a is glued with the side facing down. Thereby, the replacement packaging body W shown in FIG. 5 is formed.
