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. 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. 6 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 have been proposed to secure the opening area by making the 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 JP-A-5-132069 Japanese Patent No. 4110940 Japanese Patent Laid-Open No. 11-236058 JP 2008-18991 A JP 2011-255947 A

  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. 7 (1) is a view showing the flexible packaging bag disclosed in Patent Document 5, and FIG. 7 (2) is an enlarged view of the spout portion. This soft packaging bag which is the application of the present 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. However, when the position of the V-shaped notch b is slightly shifted, the tear of the packaging bag is detached from the cut line a and cannot be opened at the original position of the cut line a. It was found that could occur.

  The refill container described in Patent Document 6 filed by the present applicant has been made to solve this problem, and has a plurality of flaw lines along a planned opening line inclined with respect to the bent portion. It is characterized in that it is subjected to an easy-cutting process, and further, the leading end of the opening cut line is bent in a direction parallel to the planned opening line.

  According to the refill container described in Patent Document 6, the problem that the tear of the packaging bag is detached from the planned opening line at the time of opening is considerably improved, but the opening failure occurs very rarely, and further improvement is achieved. It was sought after.

  The problem to be solved by the present invention is that the opening operation of the spout is easier and more reliable in a refill container having a bent portion that can form a spout with a large area without using a separate member such as a plug. We propose a refillable container that can be refilled.

As means for solving the above-mentioned problems, the invention according to claim 1 is characterized in that a single laminate having a base material and a sealant layer is folded with the sealant layer inside, and the folded portion and the main body surface laminate. And a main body back surface laminate, and a refill container formed by sealing the periphery,
The bent portion, together with the front surface laminate, the back surface laminate, and the discharge nozzle seal portion, forms a pouring nozzle for pouring the contents,
The tip of the dispensing nozzle is sealed by a dispensing nozzle tip seal portion, and is separated along the planned opening line by holding an opening knob separated and formed by the opening cut line provided in the dispensing nozzle seal portion. To form a spout by
A plurality of laser cut lines parallel to the opening schedule line are applied to the dispensing nozzle portion including the opening opening line,
The leading edge of the opening cut line is bent in a direction parallel to the laser cut line, and the angle (α) between the leading edge of the opening cut line and the laser cut line is within ± 10 °. Oh it is,
At the tip of the opening cut line, the angle (β) formed by the laser cut line with respect to a horizontal line is 45 ° or more,
The laser-cut line in a direction that is recessed when viewed from the spout is curved to dogleg shape, the angle of the laser cut line intersects the bent portion and said 90 ° der Rukoto Refill It is a container.

  The refill container according to the present invention is provided with a plurality of laser cut lines parallel to the planned opening line, and the opening portion of the opening cut line for guiding the cut to the laser cut line is ± 10 with respect to the laser cut line. By specifying within the range of °, the cut of the laminate can be surely guided to the laser cut line.

  Delete.

  In the refill container of the present invention, since there is a bent portion on the upper side of the packaging bag, the opening direction must be opened from the bottom to the top, but at this time, the angle of the laser cut line is If it is too small (sleeping), the cut will be easier. The stability of opening is improved by setting the angle of the laser cut line to 45 ° or more.

  Delete.

In addition, according to the present invention, the angle at which the laser cut line intersects with the bent portion is 90 °, so that the detachability at the bent portion that is the end point at the time of opening becomes good, and the allowable error range in the manufacturing process And stable production becomes possible. This will be described in detail later.

Further, in the invention described in claim 2 , a laminate having at least a base material and a sealant layer is bent with the sealant layer facing outward to form a bottom tape, and between the main body surface laminate and the main body back laminate. The refill container according to claim 1, wherein the refill container has a standing pouch shape that is inserted into the container and sealed at the periphery.

The invention according to claim 3, cut open a portion of the bent portion, a refill container according to claim 1 or 2, characterized in that a content filling opening.

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, the spout can be formed easily and reliably.

  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, a plurality of laser cut lines parallel to the planned opening line are provided on the planned opening line, and the tip of the opening cut line is bent in a direction parallel to the planned opening line. By making the angle between the tip of the cut line and the laser cut line within ± 10 °, when the opening knob is pulled up, the tear of the laminate will naturally proceed along the planned opening line and spout into a predetermined position Can be formed easily and reliably.

When the angle (β) formed by the laser cut line with respect to the horizontal line is 45 ° or more at the tip of the opening cut line as in the present invention, the cut starting from the opening cut line is smoothly lasered. It moves to the cut line and can be opened stably along the planned opening line.

Further, as in the present invention, when the laser cut line is bent in the direction of dent as viewed from the spout, and the angle at which the laser cut line intersects the bent portion is 90 °, at the final point at the time of opening, The cuts in the laminated body on the back surface are easily matched, and the separation property is improved. Moreover, since the tolerance with respect to the misalignment of the bent portion is widened during manufacturing, stable manufacturing is possible.

Further, as in the invention described in claim 2 , one laminate having at least a base material and a sealant layer is bent with the sealant layer outside to form a bottom tape, and the main body surface laminate and the main body back laminate are formed. In the case of a standing pouch shape that is inserted in between and sealed at the periphery, it becomes possible to provide a large-capacity refill container having self-supporting properties, and the features of the present invention can be fully utilized.

Further, as in the third aspect of the invention, when a part of the bent portion is cut open to form the content filling opening, the other sealing portion cannot be used as the filling opening. Even in this case, 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.

FIG. 6 is a schematic view showing an example of a conventional refill container. FIG. 7 is a schematic diagram showing the flexible packaging bag described in Patent Document 5 and its spout.

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 one reference embodiment of a refill container according to the present invention. FIG. 2 is a schematic cross-sectional view showing the XX ′ cross section of FIG. 1 and shows the layer structure of the laminate constituting the refill container. FIG. 3 is an enlarged explanatory view showing details of the dispensing nozzle portion of FIG.

  As shown in FIG. 2, the refill container (1) according to the present invention is a refill container comprising a laminate having at least a base material (11) and a sealant layer (12), and is shown in FIG. As described above, one laminate is folded with the sealant layer on the inside to form a bent portion (6), a body surface laminate (2), and a body back laminate (3), and the periphery is sealed. 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.

  A plurality of laser cut lines (33) parallel to the planned opening line are provided on the dispensing nozzle portion including the planned opening line (36), and the tip (35a) of the opening cut line is a laser cut line. It is bent in the direction parallel to (33). It is an essential requirement that the angle (α) formed by the tip of the opening cut line and the laser cut line, that is, the deviation between the angles is within ± 10 °.

  The 1st characteristic in the refill container which concerns on this invention is 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.

The second feature of the refill container according to the present invention is that the opening scheduled line is held with the opening knob (34) formed separately by the opening cut line (35) provided in the dispensing nozzle seal portion (24). The spout (31) is formed by cutting along (36), and the planned opening line (36) is at least at the tip (35a) of the opening cut line of the bent part (6). A plurality of laser cut lines (33) parallel to the planned opening line are provided on the dispensing nozzle portion that is inclined with respect to the ridge line and includes the planned opening line.

  Furthermore, the tip part (35a) of the opening cut line is bent in a direction parallel to the laser cut line (33), and the angle formed by the tip part (35a) of the opening cut line and the laser cut line (33). When (α) is within ± 10 °, the cut of the laminated body starting from the tip of the opening cut line advances reliably along the laser cut line (33), and the opening is reliably performed.

  When the difference between the angle of the tip of the opening cut line and the angle of the laser cut line exceeds 10 °, the cut of the laminate starting from the tip of the opening cut line advances along the laser cut line. Without the possibility of shifting in different directions.

  Further, if the opening knob (34) is formed by a V-shaped cut or the like, it is completely separated from the spout seal part, 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 reference mode shown in FIG. 1, the main body surface laminate (2) and the main body back laminate (3) are sealed at the side seal portion (22) and the bottom seal portion (23) to form a bag shape. . In an actual container, a filling opening for filling the contents is necessary, but is omitted in FIG. In the reference mode shown in FIG. 1, a filling opening can be provided in the bottom seal part (23) or the side seal part (22). Moreover, a part of bending part (6) can be cut open and it can also be set as the opening part for filling.

  The planned 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, a laser cut line (33) is provided in the extraction nozzle part containing an opening schedule line so that it may be parallel to an opening schedule line. The laser cut line is preferably a half-cut line provided continuously on the outer surface of the main body surface laminate (2) and the main body back laminate (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. As the type of laser, a carbon dioxide laser is preferable.

  As shown in FIG. 3, it is desirable that the laser cut line (33) is equal to the angle of the opening cut line tip at the tip of the opening cut line (35a), but there is a deviation between the angles of the two. If the angle is within ± 10 °, there will be no problem that the cut is deviated from the laser cut line.

  On the other hand, the angle (β) formed by the laser cut line (33) with respect to the horizontal line at the tip (35a) of the opening cut line (35) is preferably 45 ° or more. This is because, when this angle is small, that is, when the laser cut line is laid down, the operation of opening from the lower side to the upper side becomes unstable and the disconnection of the cut tends to occur.

  On the other hand, the angle at the portion where the laser cut line (33) intersects the ridgeline of the bent portion (6) is most preferably vertical. This is because, in the manufacturing process of the refill container, normally, after forming the laser cut line (33) in one laminated body, the laminated body is bent to form the bent portion (6).

When the laser cut line (33) crosses the ridge line of the bent portion obliquely, the laminate before bending must be formed in a V shape. Next, when the bent portion (6) is formed, the bending position must pass through the vertex of the V-shape, but in reality, a slight deviation occurs.

  When the bending position is shifted, the intersection of the laser cut lines of the laminate on the front and back surfaces does not match at the bent portion, and the position is shifted to either the front or back. Then, since the cut of the laminated body that has progressed from both the front and back sides at the time of opening does not coincide with the bent portion (6), separation may be worsened.

  On the other hand, when the laser cut line (33) intersects the ridge line of the bent portion perpendicularly, even if the bent position is slightly shifted, there is no problem, and the laminate has progressed from both the front and back sides when opened. The incision is always coincident at the bent portion (6).

  Therefore, as shown in FIG. 4, the laser cut line (33) is curved in a direction that is recessed when viewed from the spout, and the laser cut line is 45 ° or more with respect to the horizontal line at the opening cut line end portion. If the angle is 90 ° at the position intersecting with the bent portion, the most stable opening property can be obtained.

  As described above, when the laser cut line (33) is curved in a concave direction when viewed from the spout, the opening area of the spout (31) is widened, and another effect of improving the pouring property is produced.

  As a laminated body used for the refill container according to the present invention, a laminated body usually used for flexible packaging bags 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.

FIG. 5 is a schematic view showing another reference embodiment of the refill container according to the present invention.
In this reference embodiment, a single laminate having at least a base material and a sealant layer is folded with the sealant layer outside to form a bottom tape (4), and a main body surface laminate (2) and a main body back laminate (3). It is made into the standing pouch shape which inserts between and seals a periphery. In the case of such a shape, since the filling opening for filling the contents cannot be provided in the side seal portion, a part of the bent portion (6) is cut open to form the 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.

  The standing pouch-shaped container can be easily made into a large-capacity container because the bottom tape (4) spreads out. 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 one laminated body at the top with the sealant layer inside, and the bent portion (6) includes the front surface laminated body (2), the back surface laminated body (3), and Together with the dispensing nozzle seal portion (24), an outflow passage for the contents reaching the dispensing outlet 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 even more effective in this reference embodiment because of the large capacity of the container.

  In order to manufacture the refill container shown in FIG. 5, the laminated body that is slit to a width approximately twice the width corresponding to the height of the container is folded at the top with the sealant layer surface facing inside, and is opposed to the main 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.

[Reference Example 1]
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, 120 μm)
The laminated body which consists of the following structures was used as a bottom tape.
<Configuration of laminate>
ONY (ONM manufactured by Unitika, 15 μm) / LLDPE (same as above, 120 μm)

A standing pouch having the shape shown in FIG. 5 was produced using the above laminate. 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 1
8 mm.
As the filling opening, a part of the bent portion was cut to form a filling opening. In addition, three linear laser-cut lines by laser processing were provided in a portion including a planned opening line to be a spout at the tip of the spout nozzle. Further, an opening cutting line was provided in the dispensing nozzle seal portion, and the tip thereof was bent in a direction that coincided with the angle of the laser cut line. α = 5 ° and β = 60 °.

[Example 1]
A standing pouch having the same shape was produced using the same material as in Reference Example 1 except that the shape of the laser cut line was as shown in FIG. α = 0 °, β = 50 °, and the angle between the laser cut line and the bent portion = 90 °.

The refillability of the refill containers of Example 1 and Reference Example 1 was evaluated. As an evaluation method, the planned cutting position of each sample was grasped with a jig, and the tear strength (N) when tearing along the laser cut line was measured. In addition, sensory evaluation was conducted on the feel of tearing when actually tearing by hand. The results are shown in Table 1.

Thus, it can be seen that the refill container according to the present invention is excellent in openability when actually opened by hand, and in particular, in Example 1 in which the laser cut line is curved, the effect is high.
