Description

  The present invention relates to a film container mainly composed of a film on both sides. More specifically, the present invention relates to a film container having a reseal function.

  Film containers for storing liquid contents such as shampoos, rinses, body soaps, liquid detergents, toiletries such as softeners, powders and granules of sugar, salt, sesame, coffee, cocoa powder, seasonings, etc. There are film containers to store, but normal film containers cannot be resealed after opening.

  Various improvements have been made to solve this problem. For example, there is a film container provided with a pouring path and a spout with a screw cap provided at the tip of the pouring path so that it can be resealed. There is also a film container in which a chuck is provided in the vicinity of the opening so that the chuck can be resealed.

  In addition to the front and back films, these require caps, spouts, chuck tapes, and other parts, and require a processing step to bond them. Since the cost is high for the member, there is a problem that it is difficult to use unless the price of the content is high to some extent.

  In order to solve such a problem, Patent Document 1 proposes a packaging bag including a sealing tool in which a sealing hole is provided in a seal portion at at least one end of an elongated bag.

However, this packaging bag is limited to a tubular film container made of a film having the same width as the spout. Moreover, since the sealing tool is provided at one end of the packaging bag, the sealing tool is opened, the sealing tool is separated from the packaging bag, the contents are discharged, and the portion where the film is squeezed is sealed. It is a mechanism for sealing by inserting into the hole.
If the amount used for the first time is small, the end of the packaging bag cannot be squeezed to the extent that the spout is passed through the sealing tool.
In addition, since the sealing tool is not bonded to the packaging bag, it is easy to lose, and it is necessary to fold or squeeze the film that composes the packaging bag so that it passes through the hole. There were also problems such as difficulty in using films made of thick materials and other materials.

  Known documents are shown below.

It is an example of the resealable film container of this invention, and is the front view in the film container before the opening, and sectional drawing of the vicinity of a spout. It is an example of the resealable film container of this invention, and is the front view in the film container resealed after opening a spout, and sectional drawing of a spout vicinity. In the resealable film container of this invention, it is a figure which shows the state which pushed and bent the resealing member from right and left, and opened the extraction part at the time of opening. It is a perspective view which shows the example of the resealing member used for this invention. It is another example of the resealable film container of this invention, and is a front view in the film container before the opening.

The present invention will be described below with reference to the drawings.
FIG. 1-1 is an example of the film container 100 of the present invention, and is a front view of the film container before opening.
The film container 100 is a bag in which the front film 1 and the back film 10 are combined and sealed on four sides. In this figure, a standing pouch having a bottom plate 2 provided below is used.

An oblique hypotenuse seal portion 15 is provided at one corner on the upper side of the film container 100, and the spout 3 is provided by protruding from a part thereof.
The spout 3 extends outward substantially perpendicularly to the hypotenuse seal 15, runs a spout seal 33 that forms a spout parallel to the outside of the spout, and the space between the left and right spout seals is a flow path 300. It has become. In addition, a pouring tab 30 is provided at the tip of the pouring seal portion 33, which is closed when not opened, but when opening the pouring port when opened, a tear tab having an area that is easy to grasp is used. Yes.

A notch 31 is provided in the pouring seal portion 33 in the vicinity of the pouring tab 30 so that the opening 3 can be opened by tearing the pouring port 3 triggered by the notch 31. As shown in FIG. 1, a weak line 32 may be provided from the notch 31 perpendicular to the flow path 300.
A reseal member 4 is attached to the outside of the vicinity of the inclined seal portion 15 at the base of the spout 3. The resealable member 4 is a plastic molded product, and is further connected to a fixing portion 40 that is fixed to the front film 1 or the back film 10, arm portions 42 that extend from the left and right sides of the fixing portion, and the arm portions. It is comprised with the horizontal part 43 facing the fixing | fixed part. A hole surrounded by the fixing portion, the arm portion, and the horizontal portion is the insertion portion 41.
The left and right arm portions are provided at positions away from the flow path and the extraction seal portion. That is, since the width of the insertion portion 41 is larger than the width of the extraction portion 3, the extraction portion 3 is inserted into the insertion portion 41 without being bent or distorted in the width direction. I can do it.
Therefore, when the pouring part 3 is inserted into the insertion part 41, the front film 1 and the back film 10 can be fitted in a flat plane, so that it can be tightly sealed.

1-2 is an XX cross section in the film container 100 of FIG. 1-1, is parallel to the flow direction of the flow path 300 in the vicinity of the film container outlet before opening, and the front film 1 and the back film 10. It is sectional drawing cut | disconnected by the surface perpendicular | vertical to.
The resealable member 4 is fixed by an adhesive such as a hot-melt adhesive or a double-sided tape so as to follow the front film 1 or the back film 10 on the fixing portion 40 side.

FIG. 2A is an example of the film container 100 of the present invention, and is a front view showing a state after the extraction part 3 of the film container of FIG.
At the time of opening, the extraction tab 30 is cut at a right angle to the flow path from the notch 31 along the line of weakness 32, and the extraction tab 30 is separated from the film container 100 and opened.
In order to eliminate the dispensing tab 30 and reseal the opened dispensing portion 3, the opened tip of the channel 300 is inserted into the insertion portion 41.
At this time, the tearing position for opening the tip of the pouring part is formed closer to the tip than the side hanging part 43. For this reason, the pouring part 3 is inserted into the insertion part 41, and the front and back film gaps are widened at the tip of the part where the front film 1 and the back film 10 of the pouring part are greatly bent and closely adhered. The tip of the part does not come off easily, the blockage is not released, and the resealed state is easily maintained.

FIG. 2-2 is a cross-sectional view taken along the line XX in the film container of FIG. 2-1.
The fixing part 40 is fixed to the front film 1 side, the unsealed tip of the pouring part 3 is inserted into the insertion part 41, and the flow path 300 of the pouring part is largely bent at the upper end of the fixing part 40.
The pouring portion is fused in a narrow range on the left and right sides, and the front film 1 and the back film 10 are strongly pressed against each other at the portion where the flow path 300 provided between the pouring seal portions is strongly bent. There is no gap between the films, and the sealed state of the container can be maintained.

In particular, the pouring part 3 has such a length that it protrudes to the tip side from the tip of the horizontal part of the resealing member 4, so that the tip of the pouring part 3 protrudes first from the insertion part of the resealing member 4. Can be inserted. For this reason, the tip of the flow path protruding from the tip of the insertion portion 41 is somewhat widened, which is a resistance against the extraction portion 3 being pulled out, and it is easy to keep the flow passage closed in the extraction portion 3.

FIG. 3 is a view showing a state in which the contents are poured out after the film container is opened. Of course, the same applies to a state where the pouring part is unblocked from the resealed film container.
FIG. 3-1 is a front view showing the entire film container, and shows a state immediately before the extraction with the extraction part removed from the insertion part.
In this state, in a state where the contents are liquid and sufficiently filled, it can be poured out by simply pressing a portion other than the pouring portion of the film container from the outside. However, when the contents are liquid but the remaining amount is small, or when the contents are powder or granules, it is difficult to pour out.

Even in such a case, as shown in FIG. 3A, the left and right sides of the reseal member 4 are removed as shown in the cross-sectional view in the vicinity of the fixed portion in FIG. 3B with the extraction portion 3 removed from the insertion portion 41. When the end portion is pushed and deformed so that the cross section becomes a bow, the flow path 300 opens, and the contents can be poured out when the tip is directed downward.
That is, in FIG. 3-2, the front film 1 is fused to the fixing portion 40, but only the film on the front and back of the film container is always adhered to the fixing portion 40.
Here, in the pouring part, the front film 1 and the back film 10 have the same length, and the pouring seal parts 33 at the left and right end parts are fused. For this reason, in this figure, when the front film 1 is fused to the fixed portion 40 and the resealing member 4 is pushed from the left and right, the resealing member 4 is distorted and the front film 1 is bent in an arc shape. Mu
At that time, the right and left end portions of the back film 10 are drawn inward in the same manner as the front film 1, but the bent diameter is reduced by the thickness of the film, and the back film 10 is compressed so as to be drawn more narrowly than the front film 1. Will come to be.
For this reason, the back film 10 cannot remain in close contact with the inside of the front film 1, and a surplus film length occurs, and a bending phenomenon occurs due to the difference in length.
That is, the back film 10 bends away from the front film 1 inwardly at the center of the flow path, and the flow path 300 expands and penetrates, so that the contents can be poured out.

FIG. 4 is a perspective view showing an example of the reseal member 4 used in the present invention.
FIG. 4A is the resealing member 4 in a form in which the horizontal portion 43 connects the left and right arm portions 42.
The insertion part 41 is a slit-like hole, and its width W is wider than the width of the extraction part.
The distance between the fixing portion 40 and the horizontal portion 43, that is, the gap d of the insertion portion 41 is a gap slightly wider than the total thickness of the front film and the back film.

FIG. 4B shows the resealing member 4 in a form in which the horizontal portion 43 is divided into left and right hands at the center and the left and right arm portions 42 are connected.
In this resealable member, since there is no center, even if a film with low flexibility is used, such as the front film and the back film constituting the pouring part are thick or hard using a biaxially stretched film, etc. It is easy to insert into the insertion portion 41.

FIG. 5 shows another example of the resealable film container according to the present invention. The spout 3 is a film container provided on the center line of the container, and is a front view of the film container before opening.
The seal part on the upper side is inclined to the left and right, and the center is the extraction part 3. Of course, the inclination of the seal portions on the left and right sides of the upper side has the effect of facilitating taking out the contents, but there is no problem even if it is not inclined.
Further, there is no bottom plate like a standing pouch, and a single film is folded on the lower side and the sealant side is aligned, and is sealed in a simple bag shape on three sides.
The contents may be filled by inserting a tube from the pouring part 3 and filling it, and sealing the pouring tab 30 after filling, or filling from one side of the upper side seal part and sealing after filling. It doesn't matter.
The resealing member 4 is adhered later.

Although the film container of the present invention is as described above, the laminated film used for the front film 1 and the back film 10 used for the film container 100 depends on the contents and the storage conditions thereof, but the substrate It is preferable to use a biaxially stretched film.
By using a biaxially stretched film as a base material, a repulsive force is generated like a spring, and it becomes resistance in the gap of the narrow insertion part, and it becomes difficult for the pouring part to come out from the gap of the reseal member, At the bent portion, the holding gap is surely crushed and closed to prevent outflow of contents, moisture from the outside, and other entry.
As a configuration of such a laminated film, a two-layer laminated film in which a biaxially stretched polyethylene terephthalate film and a linear low density polyethylene film are bonded can be considered.
In addition, biaxially stretched polyethylene terephthalate / biaxially stretched polyamide / maleic anhydride modified polyethylene / high pressure method low density polyethylene,
Biaxially stretched polyethylene terephthalate / silicon oxide deposited layer / linear low density polyethylene,
A configuration such as biaxially stretched polyethylene terephthalate / low density polyethylene / aluminum foil / linear low density polyethylene can be considered.

The resealable member 4 can be manufactured by plastic injection molding or compression molding.
Examples of materials include high-pressure low-density polyethylene, medium-density polyethylene, linear low-density polyethylene, high-density polyethylene, polypropylene, ethylene / polypropylene copolymer resin, polymethylpentene, cyclic polyolefin, and ethylene / vinyl acetate copolymer. Polyolefins, styrene, high-impact styrene, styrene resins such as acrylo-butadiene-styrene copolymer, acrylo-styrene copolymer, and other general-purpose products such as polyoxymethylene, polyamide, polycarbonate, polysulfone, polyethylene terephthalate, polymethylene terephthalate In addition to thermoplastic resins, elastomers such as olefin elastomers and polyester elastomers, and thermosetting resins such as phenol resins may be used. It may be a recycled resin, such as Ren and polyethylene terephthalate resin.
Select and use materials that are unlikely to deteriorate or deteriorate depending on the contents.

The film container 100 of the present invention is as described above, and has an extraction tab 30 to tear and open the extraction part. The opened film container bends the flow path of the extraction part, The extraction part can be easily re-sealed simply by inserting and fixing the extraction part into the insertion gap surrounded by the fixing part and the horizontal part.
In addition, since the re-sealing member is provided on the outer surface of the dispensing portion, it can be easily resealed regardless of the initial use amount of the contents, and the resealing member is fixed to the film container, so there is no risk of loss. .
In addition, since the film container of the present invention can be easily made by simply changing the shape of the film container by simply providing an elongated pouring part and adhering a simple and inexpensive reseal member, a general conventional production line Can be used as it is, so that the productivity is high and the merit of the present invention is great.
