JP6975889B2 - Stick-on nozzle for film pack and content application method - Google Patents

Description

The present invention relates to a nozzle for a film pack, and more specifically, to a stick-on nozzle to be attached to a film pack.

A film pack is a film in which a fluid content such as an adhesive or a sealing material is encapsulated in a resin thin film material (film) laminated with aluminum or the like. As shown in FIG. 10, a normal film pack FP is manufactured by filling a bag-shaped film with contents and sealing both ends of the squeezed film with a caulking tool, and has a shape similar to that of a so-called sausage. It is a structure.

Compared to paper tube cartridges and plastic cartridges, which require the container manufacturing process and the container filling process to be performed separately, the film pack FP performs the container manufacturing process and the container filling process at the same time. As you can see from the manufacturing process, it can be provided at low cost, and since the film is a soft packaging material, waste after use can be reduced, so in recent years it has been mainly used for commercial purposes. It is widely used in Japan.

Originally, the film pack FP applies the contents after using a dedicated caulking gun (extrusion mechanism) as shown in Patent Document 1, for example, but without using such a caulking gun, "hand drawing" is performed. There are many cases where the contents are applied by "". Hand squeezing is a method of applying the contents while literally grasping the film pack FP directly with your hand and squeezing it out. You will push things out. Therefore, the workability tends to be unstable as compared with the application work using a caulking gun, for example, the contents may be applied more than necessary or may not be applied to the intended place.

However, there is a strong desire to apply by hand drawing, and an improved film pack for hand drawing (hereinafter referred to as "film pack for hand drawing") is also provided. Specifically, one in which a nozzle is attached instead of closing one end of the film pack by caulking, and one in which a nozzle is attached to one end and the other end is a heat seal are provided. Although such a film pack for hand drawing certainly makes the coating work more efficient, the manufacturing process is different from that of the normal film pack FP, so dedicated filling equipment, packaging equipment, and other production equipment are newly installed. There is a need to. As a result, the film pack for hand drawing becomes relatively expensive, that is, the major feature of the film pack FP that it can be provided at low cost is lost.

Therefore, even when the film is applied by hand drawing, it is still preferable to use the ordinary film pack FP, but as disclosed in Patent Document 1 and Patent Document 2, the ordinary film pack FP is used. When using it, it is assumed that a coking gun is used to the last, and so far no proposal has been made regarding the technique of applying a normal film pack FP by hand drawing.

As described above, when applying the contents of a normal film pack FP by hand drawing, it is necessary to cut a part of the film pack FP with a cutting tool such as a cutter. As a part for cutting the film pack FP, it is conceivable to cut the side surface of the middle part (FIG. 10) of the film pack FP. The surface of the film FP is gradually torn from the small holes due to the internal pressure, and as a result, the small holes are expanded and an opening larger than necessary is formed. As a result of the formation of such a large opening (protruding opening), there may be an inconvenience that an extra amount of contents may be applied or the contents cannot be applied to the intended place. Was considered unstable.

The object of the present invention is to solve the problems of the prior art, that is, a film pack in which a normal film pack FP can be stably applied by hand drawing and can be easily attached to the film pack FP. It is to provide a stick-on type nozzle and a method of applying the contents using the nozzle.

The present invention has been made focusing on the point that a nozzle provided with a discharge hole is attached to a film pack, and a nozzle having a guide groove (slit) for cutting is attached to the film pack. , It was done based on an unprecedented idea.

The stick-on nozzle for a film pack of the present invention is attached to a film pack, and is provided with a thin plate-shaped main body sheet and a discharge hole provided in the center of the main body sheet. Further, the stick-on nozzle for a film pack of the present invention may have a plurality of slits cut from the discharge hole toward the outer periphery formed on the main body sheet.

The stick-on nozzle for a film pack of the present invention may also have a slit pair (a set of two slits) formed. In this case, the two slits constituting the slit pair are arranged substantially point-symmetrically (including point-symmetrically) with respect to the center of the discharge hole.

The content coating method of the present invention is a method of coating the contents of a film pack using a sticking nozzle for a film pack, and is a method including a sticking step, a cutting step, and a coating step. Of these, in the sticking step, a sticking nozzle for a film pack is stuck on the surface of the film pack, and in the cutting step, a cutting line is formed on the surface of the film pack by cutting the surface of the film pack in the discharge hole. At this time, if a slit is formed in the main body sheet of the stick-on nozzle for film pack, it is preferable to form a cutting line on the surface of the film pack by cutting the surface of the film pack on the line portion extending the slit. Then, in the coating process, the contents of the film pack are coated by hand drawing using the cutting line and the discharge hole.

The stick-on nozzle for film packs and the content coating method of the present invention have the following effects.
(1) Since the conventional film pack can be used as it is, there is no need to modify the conventional film pack production line, and therefore an inexpensive film pack can be used as before. ..
(2) Since an opening having an appropriate size is formed by the discharge hole and the size is maintained by the main body sheet even during the coating work, the coating work by hand drawing can be stably performed.
(3) Since the film pack surface is appropriately cut off because it is guided by the slit provided in the main body sheet.
(4) By providing a sticking material such as double-sided tape on the back surface of the main body sheet, the sticking-type nozzle for film pack can be easily stuck on the front surface of the film pack.

Therefore, first, the stick-on nozzle for a film pack of the present invention will be described, and then the content coating method of the present invention will be described.

1. 1. Attachable Nozzle for Film Pack FIG. 1 shows a situation in which the adhesive nozzle 100 for a film pack of the present invention is attached to the surface of a film pack FP, and the adhesive AD is applied by hand drawing from a “discharge hole” described later. It is a partial perspective view which shows. Here, for convenience, a film pack FP in which the adhesive AD is enclosed is described as an example, but in carrying out the present invention, in addition to the adhesive AD, other fluid contents such as a sealing material are enclosed. Needless to say, the film pack FP can be used. Hereinafter, each of the main elements constituting the film pack sticking nozzle 100 of the present invention will be described in detail.

(Main body sheet)
FIG. 2 is a plan view of the film pack sticking nozzle 100 as viewed from above. As shown in this figure, the film pack sticking nozzle 100 includes a main body sheet 110 and a discharge hole 120. Further, as shown in FIG. 3, the slit 130 provided in the main body sheet 110 may be included. By providing the slit 130, the surface of the film pack FP can be easily and appropriately cut as described later, which is suitable. The main body sheet 110 has a thin plate-like shape whose thickness is extremely small with respect to the plane dimension, and has a function of securing a sticking surface for sticking to the film pack FP and a function of holding the shape of the discharge hole 120. Have. In the examples shown in FIGS. 2 and 3, the outer diameter of the main body sheet 110 is φ24 mm and the thickness is 0.5 mm.

One surface of the main body sheet 110 (hereinafter, referred to as “back surface” for convenience) secures the surface to be attached to the film pack FP. Therefore, it is desirable that the back surface of the main body sheet 110 has a sufficient sticking area and is further flat.

It is the main body sheet 110 itself that retains the shape of the discharge hole 120. When hand drawing is performed using the film pack FP to which the film pack sticking nozzle 100 is attached, the discharge hole 120 becomes a discharge port (a hole through which the adhesive AD flows out from the film pack FP) as described later. AD is applied. At this time, a considerable internal pressure (force that the enclosed adhesive AD pushes the surface of the film pack FP from the inside) acts on the discharge port, and the discharge port tends to expand due to the internal pressure. It is the main body sheet 110 that suppresses the expansion of the discharge port and tries to maintain the size of the discharge hole 120, in other words, prevents the leakage of the adhesive AD from other than the discharge hole 120 (that is, the lid). Is the main body sheet 110. Therefore, the main body sheet 110 should have enough strength to withstand the expected internal pressure.

On the other hand, since the shape of the film pack FP surface is liable to change (it tends to be a convex curved surface) during the work of hand drawing, the main body sheet 110 attached to the film pack FP surface also follows the deformation. It should be easily deformable. That is, it is desirable that the main body sheet 110 has a strength sufficient to withstand the internal pressure during manual drawing and has a property of being deformed following the surface of the film pack FP. For example, the material is polypropylene (PP: Polypropylene), polyethylene (PE: Polyethylene) and the like can be exemplified. Of course, the main body sheet 110 can be made of other materials, not limited to PP and PE, and the plane dimensions and the thickness dimensions can be appropriately designed according to the combination with the materials. Further, the planar shape of the main body sheet 110 may be a circle as shown in FIGS. 2 and 3, a rectangle as shown in FIG. 4, or another shape may be selected.

(Discharge hole)
As shown in FIGS. 2 to 4, the discharge hole 120 is a small hole provided in the central portion of the main body sheet 110, and is an opening that penetrates the main body sheet 110. Even if the film pack sticking nozzle 100 is attached to the film pack FP, the surface of the film pack FP is exposed in the discharge hole 120, so that the film pack FP surface can be cut off with a cutter or the like, whereby the discharge hole 120 discharges. It functions as an exit. In addition, in the example shown in FIGS. It can be appropriately designed according to the above.

(slit)
As shown in FIGS. 3 and 4, the slit 130 has a groove shape provided in the main body sheet 110. More specifically, the slit 130 is a small groove cut from the inner peripheral side of the main body sheet 110 (that is, the outer peripheral side of the discharge hole 120) toward the outer peripheral side of the main body sheet 110 (however, it does not penetrate to the outer circumference). A plurality of slits 130 are provided for one main body sheet 110. When the surface of the film pack FP of the discharge hole 120 is cut with a cutter or the like, the slit 130 explicitly cut serves to guide the cutting position.

Although it has been explained that a plurality of slits 130 are provided for one main body sheet 110, it is preferable that the number of slits 130 installed is an even number and the two slits 130 are arranged so as to face each other. The combination of the two slits 130 that are arranged so as to face each other is referred to as a "slit pair" here for convenience.

FIG. 5 is a plan view of the film pack sticking nozzle 100 shown in FIG. 3 in which a slit pair is shown by a broken line frame. In this figure, the first slit 130a and the third slit 130c form the first slit pair 131, and the second slit 130b and the fourth slit 130d form the second slit pair 132. Then, the first slit 130a and the third slit 130c constituting the first slit pair 131 are arranged so as to be substantially point-symmetrical with respect to the center (center point 120p) of the discharge hole 120, and the second slit. The second slit 130b and the fourth slit 130d constituting the pair 132 are arranged so as to be substantially point-symmetrical with respect to the center point 120p. In this way, by arranging the two slits 130 constituting the slit pair so as to be substantially point-symmetrical (including point-symmetrical) with respect to the center point 120p, the cutting position in the discharge hole 120 portion is more explicitly guided. You can do it. Although FIGS. 3 to 5 show an example in which the four slits 130 are arranged in a so-called cross shape, the present invention is not limited to this, and any even-numbered slit 130 is substantially point-symmetrical (including point-symmetrical) with respect to the center point 120p. ) Can be arranged.

(Auxiliary sheet)
FIG. 6 is a plan view showing a film pack sticking nozzle 100 in which an auxiliary sheet 140 is installed in a discharge hole 120 portion. As shown in this figure, the auxiliary sheet 140 is arranged so as to cover the discharge hole 120 portion, and is attached to the main body sheet 110. An auxiliary line is displayed on the auxiliary sheet 140. This auxiliary line clearly indicates the cutting position of the film pack FP surface in the discharge hole 120 portion, and is a line segment on a line extending the axis of the slit 130 toward the auxiliary sheet 140. Therefore, when the auxiliary sheet 140 is installed (that is, when the auxiliary line is shown), it is preferable to arrange the two slits 130 constituting the slit pair so as to be substantially point-symmetrical (including point-symmetrical) with respect to the center point 120p. For example, in FIG. 6, a first auxiliary line 141 can be written so as to connect the first slit 130a and the third slit 130c (first slit pair 131), and the second slit 130b and the fourth slit can be drawn. The second auxiliary line 142 can be written so as to connect 130d (the second slit pair 132).

Since the auxiliary line clearly indicates the cutting position of the film pack FP surface in the discharge hole 120, the auxiliary sheet 140 on which the auxiliary line is written is naturally cut by a cutter or the like. Further, when the adhesive AD of the film pack FP is applied by hand drawing, the discharge hole 120 covered with the auxiliary sheet 140 needs to serve as a protrusion. Therefore, the auxiliary sheet 140 is preferably one that can be easily cut and easily torn (or rolled up) by the internal pressure at the time of manual drawing, and is preferably made of a material that is at least thinner than the main body sheet 110 and has low strength.

(Attachment material)
As described above, the back surface of the main body sheet 110 secures a sticking surface to the film pack FP, that is, the sticking nozzle 100 for the film pack is stuck in a state where the back surface of the main body sheet 110 and the front surface of the film pack FP are in contact with each other. Will be done. When attaching the film pack sticking nozzle 100 to the film pack FP, it is possible to apply an adhesive or the like to the back surface of the main body sheet 110 (or the front surface area of the corresponding film pack FP) and then attach the film pack in advance. It can also be attached using the adhesive material provided on the back surface of the main body sheet 110. As the sticking material, various conventionally used techniques such as double-sided tape and a combination of an adhesive and a release paper can be adopted. In particular, it is advisable to provide a sticking material on the back surface of the main body sheet 110 in advance because the work can be performed immediately after sticking.

2. 2. Content coating method Next, the content coating method of the present invention will be described with reference to the drawings. The content coating method of the present invention is a method using the film pack sticking nozzle 100 described so far, and therefore, the description overlapping with the content described in the film pack sticking nozzle 100 is described here. To avoid this, only the content peculiar to the content coating method of the present invention will be described. That is, the contents not described here are the same as those described in the film pack sticking nozzle 100.

FIG. 7 is a flow chart showing the flow of the main steps of the content coating method of the present invention. As shown in this figure, in carrying out the content coating method of the present invention, first, the film pack sticking nozzle 100 is stuck at a predetermined position on the film pack FP surface (Step 10). At this time, it is advisable to mark the approximate position of the film pack FP surface to be affixed, and to perform cleaning to remove unnecessary substances such as oil and dust at the position. The sticking nozzle 100 for a film pack can be attached by using an adhesive or the like applied to the back surface of the main body sheet 110 (or the front surface area of the corresponding film pack FP), or to the back surface of the main body sheet 110 in advance. As described above, the provided adhesive can also be used.

When the stick-on nozzle 100 for a film pack is attached, the surface of the film pack FP in the discharge hole 120 is cut off with a cutting tool such as a cutter (Step 20). At this time, it is advisable to set the cut line CL as shown in FIG. 8 and then excise. If the slit 130 is not provided, the cut line CL can be appropriately marked by visual measurement. On the other hand, if the slit 130 is provided, the axis of the slit 130 is extended into the discharge hole 120 as shown in FIG. It is advisable to write the cut line CL in. Further, the cut line CL may be set by actually writing on the surface of the film pack FP with a writing tool or the like, or may be set by eye measurement without actually writing. Of course, when the film pack sticking nozzle 100 on which the auxiliary sheet 140 is installed is used, the auxiliary line of the auxiliary sheet 140 can be used as the cut line CL.

When cutting the surface of the film pack FP with a cutting tool such as a cutter, only the discharge hole 120 can be cut, or the surface of the main body sheet 110 can be cut from the inside of the slit 130. For example, when a cutter knife is used as a cutting tool for cutting, the cutting direction of the cutter knife is guided by cutting from the inside of the slit 130, and the cutting can be performed more smoothly, which is suitable. When the cut line CL portion of the discharge hole 120 or the inside of the slit 130 and the cut line CL portion of the discharge hole 120 are cut off, the cut line 200 is formed as shown in FIG.

When a predetermined portion of the surface of the film pack FP is cut off to form a cutting line 200, the adhesive AD in the film pack FP is applied by hand drawing as shown in FIG. 1 (Step 30). At this time, due to the action of the internal pressure by the hand drawing, the surface of the film pack FP is torn (or rolled up) starting from the cutting line 200, and the discharge hole 120 serves as a protrusion and is sealed. Agent AD is applied.

The stick-on nozzle for film packs and the content coating method of the present invention can be effectively used when various fluid contents such as an adhesive and a sealing material are coated. When the contents are used as an adhesive, it can be used in residential buildings such as condominiums and detached houses, commercial buildings such as office buildings and stores, and various buildings such as school buildings and warehouses. be able to.
