Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a manufacturing method of a container with a mouth member formed of a flexible sheet body, the container, and a long sheet body.
[0002]
[Prior art]
Conventionally, containers filled with soft drinks such as tea and juice include containers and metal can containers (rigid containers) equipped with cylindrical labels on rigid containers such as glass and plastic, and synthetic resin films. A container (a container with a mouth member) in which a mouth member that functions as a straw is inserted and attached to an upper edge portion of a flexible container body formed by forming a sheet body into a bag shape is known.
[0003]
On the other hand, in order to promote sales of beverage products, prize campaigns such as various prizes are frequently conducted by the purchasers applying. When participating in a campaign, for example, an application sticker attached to a container as a campaign label is affixed to a postcard and mailed, and the ID number attached to the campaign label is notified to the campaign organizer. By doing so, the result of the winning will be revealed.
[0004]
[Problems to be solved by the invention]
The container used for the campaign was only the rigid container, and the container with the mouth member was not used for the campaign. Thus, the following things can be considered as a factor that the container with the mouth member is not used in the campaign. That is, when a campaign label is attached to the rigid container, it is generally attached using a tack labeler or the like on a conveyor on which a container filled with contents is transferred. Because the attached container is in the form of a flexible bag, it is difficult to transport in a certain state, and the container body is easily deformed, so the workability of attaching the campaign label is poor. Conceivable.
[0005]
Therefore, the present invention has been made to solve the above problems, and an object of the present invention is to facilitate a campaign using a campaign label even in a container with a mouth member.
[0006]
[Means for Solving the Problems]
The present invention has been made to solve the above problems, and a manufacturing method of a container with a mouth member has a gusset formed by bending a sheet body inwardly on both sides of a flexible front and back surface piece. A method for manufacturing a container with a mouth member in which a long sheet body connected to a container body is cut into a predetermined length to form a container body having a gusset, and a mouth member is attached to the upper edge of the container body. In the above, the campaign label is attached to the surface of the long sheet body before the cutting and the corresponding portion of the folded gusset .
[0008]
Therefore, since the campaign label is stuck to the flat and long long sheet body before cutting, the label sticking operation can be continuously and reliably performed.
[0010]
Further, by attaching a campaign label to the corresponding portion of the folded gusset on the surface of the long sheet body before cutting, a flat surface portion that is not easily deformed even when pressed from the surface by the folded gusset. Since the label is attached to the substrate, more stable high-speed processing becomes possible.
[0011]
The container as a container with a mouth member is characterized in that a container body formed by forming a gusset that is folded inwardly from a front and back surface piece from a flexible sheet body, and a mouth member attached to an upper edge portion of the container body. In the container with a mouth member provided, a campaign label is attached to at least one surface of the front and rear surface pieces and a corresponding portion of the folded gusset .
[0013]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below.
1 to 3 show a first embodiment of the present invention. Reference numeral 1 denotes a mouth provided with a mouth member 3 at an upper edge portion of a container body 2 formed in a predetermined shape (for example, a rectangular shape in front view). The container with a member is shown.
[0014]
The container body 2 is formed into a bag shape from a sheet body piece made of a laminated film having a gas barrier property whose inner surface is formed of a heat-fusible resin, for example, and the container body 2 can be self-supporting. .
[0015]
Specifically, as shown in FIGS. 1 and 3, the container main body 2 includes front and rear face pieces 1 a and 1 b and gussets 5 a and 5 b on both sides connected to each other through corner parts 4. Of the four corners 4, the three corners 4 a are formed by bending the sheet body, and the inner surface side of the sheet body is heat-sealed with a predetermined width and protrudes to the outer surface side. Moreover, the other corner | angular part 4b is formed by heat-sealing both edge parts of a sheet | seat body.
[0016]
Further, the container body 2 may be composed of a pair of front and rear face piece sheet bodies and a gusset sheet body, in addition to being formed from a single sheet body as described above. In the figure, for convenience, the adhesion portion 6a of the sheet body is indicated by shading.
[0017]
The inner surface of a film obtained by laminating a polyester film such as polyethylene terephthalate or a polyamide film and a gas barrier film such as an aluminum foil, an ethylene vinyl alcohol copolymer film, or a film on which an inorganic substance is deposited It is possible to use any material such as a laminated film with a layer of heat-sealable resin such as polyethylene or polypropylene, or other synthetic resinous film. What is necessary is just to be able to store a thing to be stored.
[0018]
The mouth member 3 is bonded to the upper edge of the opening of the front and rear face pieces 1a, 1b, and the upper part thereof extends to the outside of the container main body 2 and serves as a filling port or a pouring port for filling material.
In addition, the mouth member 3 has a dispensing auxiliary portion 3a that extends in the container main body 2 and has a substantially cross shape or a cylindrical shape in cross section.
[0019]
The mouth member 3 is made of, for example, a heat-sealable synthetic resin such as polyethylene or polypropylene. Moreover, it can be used also for fluid foods, such as liquids, such as a drink, and a jelly form as to-be-filled material. A cap 7 is attached to the upper portion of the mouth member 3 by screwing. Examples of such a container with a mouth member include those described in JP-A-8-133308, JP-A-2000-43897, JP-A-2949694, and JP-A-2-21399.
[0020]
A campaign label 10 is attached to the surface of the front piece 1a and in the center in the left-right direction. The campaign label 10 is an application sticker or the like on which an individual display dedicated to the campaign is printed. The campaign label 10 is a film or synthetic paper made of polyethylene terephthalate, polypropylene, or the like, or a tack label in which a pressure sensitive adhesive that can be peeled off from the surface of the container and re-adhered to a postcard is applied. Since the container with a mouth member of the present invention often gets wet with water or the like, a base material having water resistance is preferable, and in particular, there is followability to deformation of the container body at the time of filling or product distribution, and wrinkles etc. are difficult to remain, and A void-containing synthetic paper having a thickness of 40 to 100 μm formed by stretching a polyolefin-based resin such as polyethylene or polypropylene containing inorganic fine particles, which is suitable for labeling by a tack labeler, is preferably used. As such synthetic paper, for example, YUPO of Oji Oil Chemical Co., Ltd. formed from a biaxially stretched layer and a uniaxially stretched layer can be used.
Further, the label 10 may be a booklet in which a plurality of sheet surfaces are detachably stacked.
[0021]
Further, the width L1 of the campaign label 10 is set to be smaller than the interval L2 between the front end portions of the gussets 5a and 5b folded in a flat shape as shown in FIG.
[0022]
Next, the manufacturing method of the said container 1 with a mouth member is demonstrated.
First, FIG. 2 shows a long sheet body 12 in which a large number of container main bodies 2 are continuously provided.
The long sheet body 12 is cylindrical and is obtained by winding a long film that is gusseted by folding both sides inward. Further, although the gussets 5a and 5b are folded in half, each campaign label 10 is adhered to the surface of the front piece 1a at a predetermined interval so as to be positioned at the interval formed between the respective leading ends. Yes.
[0023]
As a means for adhering the campaign label 10, a flat sheet-like long sheet body obtained by winding the sheet body made of the laminated film into a cylindrical shape and a flat shape or wound up once in a roll shape after the bag is formed. 12, the campaign labels 10 are sequentially and continuously attached to the predetermined positions with a labeler or the like at predetermined intervals.
[0024]
Thus, since the campaign label 10 is stuck on the flat sheet 12 in a flat state, it can be easily stuck continuously, and the sticking work can be easily automated. Further, the long sheet body 12 to which the campaign label 10 is attached is wound up in a roll shape, but as shown in FIG. Since it is affixed to the thin part of only the piece 1a, 1b part, it is hardly bulky.
[0025]
Next, when the elongate sheet body 12 is set on a reel of a conventionally known container manufacturing apparatus and is rewound, the virtual portion 6b is cut with a cutter as shown in FIG. The container body 2 and the scrap 20 cut to form the bottom of the next container body 2 are formed at the same time.
[0026]
Thereafter, the mouth member 3 is inserted into the upper edge of the container body 2 formed in the bag shape, and the container body 2 and the mouth member 3 are attached by a sealing device, and the container with the mouth member is automatically installed. Manufacturing. The container with the mouth member created in this way is filled with an object to be stored via the mouth member 3. At this time, if the container body 10 swells but the campaign label 10 is formed from the void-containing synthetic paper made of the polyolefin-based resin, it easily follows the deformation of the container body, and can be peeled off and re-adhered. Despite the use of the agent, there is no inconvenience at the time of filling such as peeling.
[0027]
In addition, according to the manufacturing method of the present invention, the label 10 is applied before the mouth member 3 having the extraction assisting portion 3a is attached, so that it can be easily applied to the portion corresponding to the extraction assisting portion 3a at the time of application. .
[0028]
Further, the position of the campaign label 10 is not limited to the first embodiment, and the embodiment shown in FIGS. 4 to 6 may be used.
4 to 6 show a second embodiment of the present invention, and the campaign label 10 is provided at a portion corresponding to the gusset 5a on the surface of the front piece 1a of the container body 2. FIG. In such a case, the campaign label 10 is formed on the thick and firm flat portion (the portion that is difficult to be deformed by pressing) of the long sheet body 12 folded flat before cutting each container body 2. Therefore, it is advantageous to adhere the label 10 more stably while feeding the long and flat sheet material.
[0029]
In the first embodiment and the second embodiment, the campaign label 10 is attached to the front piece 1a. However, the campaign label 10 may be provided on the rear piece 1b or may be provided on the double-sided piece. Moreover, in the second embodiment, the campaign label 10 is provided on one gusset 5a side, but may be provided on both gussets 5a and 5b. Moreover, in the said embodiment, although the roll of the elongate sheet body 12 which stuck the label 10 for campaigns was set to the container manufacturing apparatus, it cut | disconnected while unwinding and the mouth member 3 was mounted | worn, The container with the member may be one in which the label 10 is applied while making a laminated film into a bag, cut into each container body, and then the mouth member 3 is attached to each container body with another device.
[0030]
Further, the type and application form of the campaign label 10 are not particularly limited.
[0031]
