Description

  The present invention relates to a refill container for storing toiletries such as liquid detergents and softeners, foods such as edible oil and instant coffee.

  Toiletries such as liquid detergents and softeners, and foods such as edible oil and instant coffee are stored in dedicated containers that are easy to use. The dedicated container has a solid structure and is therefore expensive, so a product with a refill container that refills only the contents is sold separately so that it can be used repeatedly when the contents are gone. It is often done.

  For example, liquid detergent containers need to be weighed and taken out each time they are used, so a rigid plastic container with a nozzle at the spout is repeatedly used so that it can be easily poured into a lightweight cup. Used as a container. In contrast to this container, as a refilling container for replenishing the contents, a flexible container made of a flexible packaging film, a container in which a spout is formed, or a container attached with a stopper is generally used. ing.

  A rigid container that is used repeatedly is designed so that it can be easily poured out.Therefore, in consideration of the convenience of the refilling operation of refilling the contents from the refilling container, There wasn't.

  On the other hand, the refill container is not always considering the convenience of the refilling operation because the emphasis is on manufacturing at low cost.

  The refill container can be opened using the nozzle provided in the container to be used repeatedly, and since the refill container is self-supporting during refilling, it does not need to be held by hand. Containers have been proposed. This hand-held refillable container is a refillable container including a coupling member that is detachably connected to an opening of a container that is repeatedly used and a container sealing member that seals the refillable container body (see Patent Document 1). .

  Since the refill container described in Patent Document 1 uses two members, ie, a coupling member and a container sealing member, in the cap portion in order to couple the reusable container and the refill container, the cost of the container is high. It must be a thing. In addition, since the refill container is used by screwing it into the opening of the container to be used repeatedly, the connection between the two is reliable, but on the other hand, it is not only cumbersome to operate but also disadvantageous in terms of the cost of the plug. There was a drawback of being.

  From the viewpoint of cost, a packaging bag in which the peripheral edges of two front and back packaging films as shown in FIG. 5 are sealed is advantageous. This refill packaging bag can be provided with a spout having an arbitrary width corresponding to the caliber of the container. However, when the spout is formed by sealing the edges of the two front and back films, When the liquid is poured out, the opening is pulled at both ends sealed, the front and back films are in a pseudo-adherent state, the outlet is clogged, and the outlet is easy to bend. However, there is a problem that the container is removed from the container that is repeatedly used.

  In order to solve the problem that the spout is blocked or bent, a part different from the film is inserted into the spout (see Patent Document 2), or the film near the spout is inflated. Many proposals have been made to secure the opening area by adopting a shape (see Patent Document 3).

  However, these packaging bags have the problem that the process of attaching separate members and the process of applying deep embossing to the film increase, and that the packaging bags cannot be neatly stacked in the packaging bag supply section at the time of filling. The problem and the basic problem that the spout formed by sealing the two front and back films has a sealing part at both ends, so the opening width becomes narrow accordingly and a sufficient opening area cannot be secured. was there. If a sufficient opening area cannot be secured, the time required for dispensing at the time of refilling will become long.

  In order to solve this problem, there has been proposed a packaging bag in which a film constituting the packaging bag is bent to form one side of the spout and the sealing portion of the spout is only one side (see Patent Documents 4 and 5). ).

JP 2004-99082 A Japanese Patent Laid-Open No. 5-132069 Patent No. 4110940 Japanese Patent Laid-Open No. 11-236053 JP 2008-18991

  In the case of a packaging bag composed of a film in which one side of the spout is bent as shown in Patent Documents 4 and 5, there is a problem that the spout is blocked and a problem that the opening area of the spout is insufficient. However, as can be seen from the spout of the flexible packaging bag shown in Patent Document 5, when the spout is set at an angle in consideration of the ease of operation during spout, the opening operability It has been found that there is a problem that becomes unstable.

  FIG. 6 (1) is a view showing the flexible packaging bag disclosed in Patent Document 5, and FIG. 6 (2) is an enlarged view of the spout portion. This soft packaging bag, which is the application of the applicant, is provided with a dot-like scratch processing c provided so as to cover the cut line a, the V-shaped cutout b, and the cut line a at the spout portion. Nevertheless, when the position of the V-shaped cutout b is slightly shifted, the tear of the packaging bag is detached from the cut line a, and the problem is that the original cut line a cannot be opened. It was found that this could happen.

  Therefore, in order to solve this problem, the applicant applied in Japanese Patent Application No. 2010-133659 to easy-cut processing consisting of a plurality of flaw lines parallel to the planned opening line on the planned opening line forming the spout, and further opening Stabilization of the openability was achieved by bending the tip of the cut line toward the direction parallel to the planned opening line.

  However, even with this means, in actual production, if the position of the flawed line on the front and back surfaces of the front and back surfaces and the folding position of the laminate on the front and back surfaces are misaligned, It has been found that there are cases where it cannot be cut well.

  The problem to be solved by the present invention is a refill container in which a single layered product is folded to form a pouring nozzle portion, and a large area spout can be formed without using a separate member such as a plug. The present invention proposes a refill container that can easily and reliably open the spout even if the position of the bent portion is difficult to be displaced.

  As a means for solving the above-mentioned problems, the invention according to claim 1 is characterized in that a single laminate having at least a base material and a sealant layer is bent with the sealant layer inside, and the bent portion and the main body surface are laminated. And forming a bottom tape by bending the sealant layer outside to form a bottom tape, and forming a bottom tape by forming a body and a main body back surface laminate, and at least a base material and a sealant layer between the main body surface laminate and the main body back surface laminate A standing pouch-shaped refill container that is inserted and sealed at its periphery, and the bent portion is slanted to pour the contents together with the front surface laminate, the back surface laminate, and the dispensing nozzle seal portion. A pouring nozzle is formed facing upward, and the tip of the pouring nozzle is sealed by a pouring nozzle tip seal portion, and the unsealing provided in the pouring nozzle seal portion A spout is formed by separating along a planned opening line with an opening knob separated by a cut line, and the planned opening line is inclined with respect to the bent portion, and the main body On the opening schedule line on the front surface laminate and the main body back surface laminate, easy-cut processing consisting of a plurality of scratch lines parallel to the respective opening schedule lines has been performed, and applied to the main body front and back surface laminates. The refill container is characterized in that one half-cut line connecting tips of a plurality of flaw lines is formed along a ridge line of the bent portion.

  The refill container according to the present invention has an easy-cut process composed of a plurality of flaw lines parallel to the planned opening line on which the spout is to be formed, and one half-cut line connecting the ends of the plurality of flaw lines. Since the half-cut line guides the folding position when the bent portion is formed, the bent portion is formed at the original accurate position.

  Even if the folding position is shifted, the half-cut line guides a break at the time of opening, so that the spout is reliably formed.

  The invention according to claim 2 is characterized in that the half-cut line formed along the ridge line of the bent portion is formed so as to avoid the dispensing nozzle tip seal portion. The refill container described.

  The invention according to claim 3 is characterized in that the opening portion of the opening cut line is bent in a direction parallel to the planned opening line. It is a container.

  Further, the invention according to claim 4 is an elongate swelled outward in parallel to the path of the pouring nozzle at the opposite position of the main body surface laminate and the main body back laminate forming the pouring nozzle. The refill container according to claim 1, comprising a plurality of convex portions.

  The invention according to claim 5 is the refill container according to any one of claims 1 to 4, wherein a part of the bent portion is cut open to form a content filling opening. is there.

  The refill container according to the present invention is formed by bending a single laminate having at least a base material and a sealant layer with the sealant layer on the inside to form a bent portion, a main body surface laminate, and a main body back laminate. Because it is a refillable container that seals, unlike plastic bottles or containers that use plastic spigots, it can be manufactured only from the laminate for flexible packaging, and can be manufactured at low cost. .

Further, the refill container according to the present invention bends one laminated body with the sealant layer inside to form a folded portion, and the folded portion includes the front surface laminated body, the back surface laminated body, and the pouring nozzle. Since the pouring nozzle for pouring out the contents was formed together with the seal portion, it was possible to stably secure a large area pouring outlet, and as a result, smooth and quick refilling operation became possible.

  Further, a laminate having at least a base material and a sealant layer is folded with the sealant layer outside to form a bottom tape, and inserted between the main body surface laminate and the main body back laminate to seal the periphery. Since it has a standing pouch shape, it becomes possible to make a refill container with a large capacity having self-supporting properties, and the features of the present invention can be fully utilized.

  In addition, the refill container according to the present invention has a good operability when the content liquid is poured out by inclining the container because the scheduled opening line forming the spout is inclined with respect to the bent portion. .

  In addition, since the easy-to-cut process consisting of multiple flaw lines parallel to the planned opening line has been performed on the planned opening line, when the opening knob is pulled up, the tear in the laminate will naturally proceed along the planned opening line. It is possible to easily form the spout at a predetermined position.

  Moreover, since the refill container which concerns on this invention formed one half-cut line which connects the front-end | tips of the some wound line given to the main body front and back laminated body along the ridgeline of a bending part, a bending part is formed. At the time of forming, this half-cut line guides the bending position, so that there is an effect that the bent portion is formed at the original accurate position.

  In addition, even if the bending position is shifted, this half-cut line induces a break at the time of opening, so that there is also an effect that a spout is reliably formed.

  In the invention according to claim 2, since the half cut line formed along the ridge line of the bent portion is formed avoiding the dispensing nozzle tip seal portion, the dispensing nozzle tip seal portion is formed. At this time, it is possible to prevent the trouble that the laminated body of the seal portion is broken and the sealant layer as the inner layer protrudes to pull the yarn.

  In the invention according to claim 3, since the tip of the opening cut line is bent in a direction parallel to the planned opening line, the opening at the time of opening more reliably proceeds along the planned opening line. There is an effect.

  In the invention according to claim 4, an elongated protrusion that swells outward in parallel to the path of the pouring nozzle at a position opposite to the main body surface laminate and the main body back laminate forming the pouring nozzle. Since there are multiple shaped parts, when the contents are poured out, it becomes difficult for the laminate on the front and back sides to adhere, causing problems such as blocking the pouring flow path and bending the pouring nozzle. It becomes difficult.

  In the invention described in claim 5, since a part of the bent portion is cut open and used as the content filling opening, the container is shaped so that the other sealing portion cannot be used as the filling opening. However, a stable filling operation is possible.

  In the refill container according to the present invention, when the nozzle of the container to be used repeatedly having a nozzle cap can be inserted into the pouring nozzle, the nozzle of the container to be used repeatedly is inserted into the pouring nozzle held horizontally. By tilting the container so that the dispensing nozzle is vertical, a refill container that enables quick refilling is obtained, and the effect of the present invention is maximized. That is, the refill container according to the present invention naturally opens the spout due to the presence of the folded portion obtained by folding one laminated body, so that it is easy to insert the nozzle of the target container, and pour it in accordance with the nozzle. By designing the size of the outlet, it is possible to make the spout exactly fit the nozzle. For this reason, after inserting the nozzle of the container to be repeatedly used into the pouring nozzle held horizontally, the refilling operation can be performed quickly by tilting so that the pouring nozzle becomes vertical.

Hereinafter, the refill container according to the present invention will be described in detail with reference to the drawings.
FIG. 1 is a schematic view showing an embodiment of a refill container according to the present invention. 2 is a schematic cross-sectional view showing the XX ′ cross section of FIG. FIG. 3 (1) is an enlarged view showing details of the dispensing nozzle portion of FIG.

  A refill container (1) according to the present invention is a refill container comprising a laminate (10) having at least a base material (11) and a sealant layer (12), as shown in FIG. As shown in Fig. 1, one laminate is folded with the sealant layer inside, to form a folded portion (6), a body surface laminate (2), and a body back laminate (3), and seals the periphery. This is a refill container.

  The bent portion (6) forms a pouring nozzle (32) for pouring the contents together with the front surface laminate (2), the back surface laminate (3), and the pouring nozzle seal portion (24). The tip of the dispensing nozzle (32) is sealed by the dispensing nozzle tip seal portion (25), and forms a spout (31) by cutting along the planned opening line (36).

  An unsealing knob (34) formed separately by an unsealing cut line (35) provided in the dispensing nozzle seal portion (24) is formed below the dispensing nozzle tip seal portion (25). By holding the opening knob (34) and cutting along the planned opening line (36), the spout (31) is formed.

  The planned opening line (36) is inclined with respect to the ridge line of the bent portion (6), and on the planned opening line, easy-cut processing (33) including a plurality of flaw lines parallel to the planned opening line (36). ) Is given. In the present embodiment, the front end portion (35a) of the opening cut line (35) is bent in a direction parallel to the planned opening line (36).

  FIG. 4 is a virtual development view showing the relationship between the scratch line and the half-cut line (7) in the easy-cut machining (33) part. In this way, one half-cut line (7) connecting the tips of the plurality of scratch lines applied to the main body front and back laminates (2) and (3) is formed along the ridge line of the bent portion (6). Has been.

  By forming a half-cut line (7) before folding the single laminate to form the bent portion (6), the half-cut line (7) guides the bending position when performing the bending process. Therefore, the bent portion (6) can be formed at the original accurate position.

  Further, as shown in FIG. 3 (2), even if the folding position is shifted, the presence of the half-cut line (7) causes the front and back surfaces starting from the opening cut line (35). Since the cut is united by the half-cut line (7), the spout is surely opened.

  In the embodiment shown in FIG. 1, parallel to the path of the pouring nozzle, at the opposing positions of the main body surface laminate (2) and the main body back laminate (3) forming the pouring nozzle (32). Three elongated protrusions (8) bulging outward are provided.

  Due to the presence of the convex portion (8), it is possible to prevent the laminated bodies on the front and back surfaces of the pouring nozzle portion from adhering to each other and block the flow path or bend the pouring nozzle portion.

The refill container which concerns on this invention has the following characteristics by having a bending part (6).
The bent portion (6) is formed by bending one laminated body at the top with the sealant layer (12) inside, and the bent portion (6) is a pouring nozzle provided at the lower portion of the bent portion. Together with the seal portion (24), the main body surface laminate (2), and the main body back surface laminate (3), an outflow passage for contents reaching the spout (31) is formed. Due to the elastic action of the laminated body to return in the bent part (6), the cross section of the outflow path is always in a state where the upper part is swollen. For this reason, it becomes possible to ensure the cross-sectional area of the spout (31) widely, and it becomes possible to discharge a large amount of contents at once.

  In addition, as another feature of the refill container according to the present invention, an opening scheduled line (34) having an opening knob (34) separated and formed by an opening cut line (35) provided in the dispensing nozzle seal portion (24) ( The structure which forms the spout (31) by cutting along 36) can be mentioned. The planned opening line (36) is inclined with respect to the bent portion (6), and an easy-cut process (33) including a plurality of flaw lines parallel to the planned opening line (36) is provided on the planned opening line. Since the leading end (35a) of the opening cut line (35) has reached the easy-cut processing part, the cut starting from the opening cut line (35) is a flawed cut line. Will surely proceed along the planned opening line (36).

  At this time, when the tip part (35a) of the opening cut line is bent in a direction parallel to the planned opening line (36), the progress of the cut at the time of opening is further stabilized.

  Further, if the opening knob (34) is formed by a V-shaped cut or the like, it is completely separated from the spout seal portion, so it may hang around and be caught unnecessarily. When it is formed by a score line as in the invention, there is an advantage that it is not hung.

  In the embodiment shown in FIG. 1, the main body front surface laminate (2) and the main body back surface laminate (3) are sealed at the side seal portion (22) and the bottom seal portion (23) to form a bag shape. . Further, a part of the bent portion (6) is cut open to form a content filling opening (41). Thus, when the opening part for filling exists in the top part of a container, there exists an advantage which becomes easy to perform filling operation of the contents.

  In the embodiment shown in FIG. 1, the bent portion (6) is disposed horizontally on the top of the refill container (1), but may be disposed vertically on the side surface of the refill container.

  Note that the scheduled opening line (36) is a virtual line indicating the opening position, but in order to clarify the opening position, printing display or the like may be actually performed. Moreover, it is preferable that an easy cut process (33) is the half cut line provided continuously in the outer surface of a main body surface laminated body (2) and a main body back surface laminated body (3). By doing so, it becomes possible to easily form the spout (31) by tearing the portion of the planned opening line (36) by hand. For the half-cut line, a method of forming with a blade and a method of forming by laser processing are generally used, but the method by laser processing is preferable because a uniform and stable cut can be formed. As the type of laser, a carbon dioxide laser is more preferable. The scheduled opening line (36) is not perpendicular to the ridge line of the bent portion (6) but is inclined as shown in FIG.

  As a laminated body (10) used for the refill container which concerns on this invention, the laminated body normally used for a flexible packaging bag can be used. As the substrate (11), paper, metal foil or synthetic resin film consisting of one layer or several layers is used. For example, low density polyethylene resin (LDPE), high density polyethylene resin (HDPE), linear low density polyethylene resin (LLDPE), polypropylene resin (PP), polyolefin resin such as polyolefin elastomer, polyethylene terephthalate resin (PET), polyester resins such as polybutylene terephthalate resin (PBT), polyethylene naphthalate resin (PEN), cellulose resins such as cellophane and cellulose triacetate (TAC), polymethyl methacrylate (PMMA) resin, ethylene- Vinyl acetate copolymer resin (EVA), ionomer resin, polybutene resin, polyacrylonitrile resin, polyamide resin, polystyrene resin (PS), polyvinyl chloride resin (PVC), polyvinylidene chloride Resin (PVDC), polycarbonate resin (PC), fluorine-based resin, synthetic resin films and paper, such as urethane resin, a metal foil or the like alone or be used in combination. The substrate (11) includes a printing layer and an adhesive layer as necessary.

  As the paper, high-quality paper, piece art paper, coated paper, cast coated paper, imitation paper, and the like can be used. When paper is used for the laminate, cracking may occur in the paper due to deep embossing, so when using it for the refill container according to the present invention, streak embossing is adopted as convex embossing and concave embossing By doing so, the laminated body using paper can be used stably. It is also effective to use paper from the viewpoint of environmental considerations.

  As the sealant layer (12), a polyolefin resin is generally used. Specifically, a low density polyethylene resin, a medium density polyethylene resin, a linear low density polyethylene resin, an ethylene / vinyl acetate copolymer, ethylene・ Ethylene resins such as α-olefin copolymers, polypropylene resins such as homopolypropylene resins, propylene / ethylene random copolymers, propylene / ethylene block copolymers, and propylene / α-olefin copolymers are used. . In addition, a multilayer film in which these resins are combined may be used.

  Specific examples of the structure of the laminate include a film composed of PET / printing layer / adhesive layer / stretched polyamide resin film (hereinafter abbreviated as ONY) / adhesive layer / LLDPE, and ONY / adhesive layer / LLDPE. , ONY / adhesive layer / ONY / adhesive layer / LLDPE, paper / LDPE / aluminum foil / LDPE, paper / LDPE, and the like.

  The standing pouch-shaped container as shown in FIG. 1 can easily be a large-capacity container because the bottom tape (4) is widened. Therefore, the feature that the pouring time in the refill container according to the present invention is short can be fully utilized.

The bent portion 6 is formed by bending a single laminated body at the top with the sealant layer inside, and the bent portion 6 together with the front surface laminated body 2, the back surface laminated body 3, and the dispensing nozzle seal portion 24, An outflow path for the contents leading to the spout is formed. In this way, particularly when the contents are liquid, when the contents are poured out, the contents smoothly flow through the linear outflow passage, so that quick dispensing is possible. This feature is more effective in this embodiment due to the large capacity of the container.

  In order to manufacture the refill container shown in FIG. 1, the laminated body which is slit to a width approximately twice the width corresponding to the height of the container is folded and opposed at the top with the sealant layer surface inside, and the body surface A laminated body (2) and a back body laminated body (3) are continuously supplied, and in the meantime, a bottom tape (4) folded in half so that the surface of the sealant layer is on the outside is continuously supplied. After performing a good seal, it is punched into a container.

Thus, the refill container according to the present invention can secure a large-area spout without using a special plastic spigot, and the size of this spout is: Since it can be designed freely according to the shape of the stopper of the intended repeated use container, it is extremely valuable as a dedicated refill container capable of quick refill operation.
Hereinafter, based on an Example, the refill container which concerns on this invention is demonstrated more concretely.

A laminate having the following configuration was used as the main body surface laminate and the main body back laminate.
<Configuration of laminate>
PET (Toray P60, 12 μm) / printing layer / adhesive layer (Toyo Morton TM272, 3 g / m ² (dry)) / ONY (Unitika ONMB, 15 μm) / adhesive layer (same as above) / LLDPE (TUX-FCS manufactured by Tosero, 150 μm)
The laminated body which consists of the following structures was used as a bottom tape.
<Configuration of laminate>
ONY (ONM manufactured by Unitika, 25 μm) / LLDPE (same as above, 120 μm)

Using the above laminate, a standing pouch having the shape shown in FIG. 1 was produced. The pouch size was 130 mm in width, 260 mm in height, and 35 mm in bottom folding. The width of the opening is about 18 mm.
As the filling opening, a part of the bent portion was cut to form a filling opening. In addition, on the planned opening line that should become the spout at the tip of the spout nozzle, an easy cut process consisting of a plurality of half-cut lines by laser processing was performed. Further, one half-cut line was provided so as to avoid the positions of the dispensing nozzle tip seal portion and the point seal portion so as to pass through the intersection of a plurality of scratch lines on the front and back surfaces.

The series of laser processing was performed before the laminated body was bent to form the bent portion. Further, an opening cutting line was provided in the dispensing nozzle seal part, and the tip thereof was bent so as to be parallel to the planned opening line.
When the openability of the refill container thus obtained was examined, it was found that opening was performed along the planned opening line with a probability of 100%, and a spout was formed.
