Description

[Detailed description of the invention] [Industrial field of application] The present invention relates to the improvement of a package in which a straw or other rod-shaped object is enclosed between two synthetic resin films having a certain width. Specifically, the present invention relates to a package that simplifies the work of pasting onto containers such as pack containers.

[Conventional technology]

Currently, paper containers called pack containers as shown in FIG. 5 are used as containers for selling juices, milk, and the like. Juuse in such a container A,
When milk or the like is stored and sold, a straw is attached to the container A as an accessory, but the straw is usually packaged for hygienic reasons. Furthermore, there are cases in which yogurt, frozen desserts, etc. are placed in a different type of container, and a synthetic resin spoon is wrapped and attached to the outer surface of the container.

Such packages usually consist of individual straws and spoons, or continuous packages in which straws and other rod-like objects are enclosed in parallel and at regular intervals between two overlapping films. (See Figure 4), and in this case, the continuous package D
is divided between rod-like objects and attached to the container A as individual packages C in which one rod-like object is packaged.

Therefore, when attaching each package C to the container A, conventionally, the package C is attached using tape or the like.
For example, by pasting on the side of container A,
As shown in Publication No. 22428, a hot-melt adhesive is sprayed from the nozzle of a sprayer on the adhesion point on the side of the container in advance on the conveyor line, and the package containing the straw is moved and pasted on the side of the container. I was wearing it. Further, Japanese Utility Model Application Publication No. 58-180103 discloses that a package containing a straw is attached to an adhesive portion previously applied to a predetermined location on the outer surface of the container in the same manner as described above.

[Problem that the invention attempts to solve]

As described above, when attaching conventional packages such as straws to containers, it is very difficult to mechanically handle the very light straws in packages containing individual straws. For this purpose, tape or the like is often used, which is cumbersome and inefficient as it is a manual process.On the other hand, when continuous packages are cut into individual packages and pasted onto containers, it is generally done on a conveyor line. Although it is efficient to spray the hot-melt adhesive onto the containers that are being transported one after another, it requires a hot-melt adhesive spraying device, which inevitably increases the cost of the device. In addition, in this case, the attachment device, which uses a fluid adhesive using a sprayer, is easily soiled, leading to troublesome maintenance, and if the spraying accuracy is poor, the package may come off from the adhesive part of the container and the intended purpose may not be achieved. The drawbacks such as lack of availability were unavoidable. The present invention was devised in view of the above points, and does not require work such as spraying adhesive onto the container, and simply heats and presses the part of the package that is attached to the container from the back side. It is easy to attach packages, and it avoids increasing the cost of package attaching equipment, reduces the amount of dirt on the equipment, makes equipment maintenance easier, and makes it possible to always perform uniform and high-quality attachment. The purpose of this project is to provide packaging for straws and other stick-like items.

[Means to solve the problem]

For this reason, in the present invention, the rod-shaped object 3 is placed between two films 1 and 2 on the flat surface of the film opposite to the protruding part of the package C at a temperature higher than the melting point of these films 1 and 2. A hot-melt adhesive with a low melting point is applied to a pair of areas 4, 4 parallel to the left and right edges 5, 5 of the film at a predetermined distance a in the center, preferably in a staggered bead shape. form the package.

[Effect]

By doing this, when attaching the package C containing the straw or other stick-like object 3 to the side surface of the container A, both sides 6 of the protruding part of the package C are heated to a predetermined temperature of a predetermined size. When pressed with a heating member heated to Can be reliably bonded without making a mess.

〔Example〕

Embodiments of the present invention will be described based on the drawings.

In the case of a single package containing one straw or other stick-like object 3, as shown in FIG. One side of the film 2 is made to protrude in the width direction at the center of its short length, a straw or other rod-shaped object 3 is stored in the recess, and this film 2 is covered with another flat film of a predetermined width. , the opposing side edges of both films 1 and 2 in the width direction are made to match, and both films 1 and 2 are welded over the entire width at the flat overlapping surfaces on both sides of the protrusion, and the left and right side edges 5 are welded together. , 5 are welded to form films 1 and 2.
A straw or other stick-like object 3 is stored in between, and these films 1, 3 are placed on the flat surface of the film 1 side.
A hot-melt adhesive with a melting point lower than that of No. 2 (hereinafter referred to as
(referred to as hot melt) is applied in a staggered manner in the form of beads (granules) to a pair of areas 4, 4 of a predetermined width b, spaced apart by a predetermined distance a, parallel to the left and right edges 5, 5 of the film, and bonded. form a section. FIG. 2 is an enlarged plan view showing the state of hot melt application in the area 4 where the adhesive is applied, and 4a represents beads (grains) of hot melt arranged in a staggered manner. FIG. 3 is an enlarged cross-sectional view of the package C shown in FIG. 1 taken in a direction perpendicular to the stick 3 in the adhesive application area 4, and shows the stick (straw) 3 enclosed in the protrusion. This is an example of a case where the overlapping parts of the film on both the left and right sides of the protrusion are welded so that a gap X exists between the flat film 1 on the upper side of the drawing.
The adhesive 4a is shown to be applied in the form of beads (grains) on the upper surface of the figure. The gap X is provided to prevent the film 1 from being damaged even if the rod-shaped object 3 moves somewhat between the films 1 and 2.
It is sufficient that a gap X is formed between at least one of the films 1 and 2 or between the films 1 and 2.

Figure 4 shows that when producing such a single package C, a continuous package D is made in which a large number of straws and other rod-like objects are enclosed in parallel and at regular intervals between two overlapping films. This figure shows a continuous package D that is separated at the film polymerization part between the sticks so that it can be used as an individual package C in which one stick is wrapped. That is, a thin strip of polypropylene of a predetermined width,
A film 2 made of synthetic resin such as polyethylene is made to protrude on one side at a constant interval without being plastically deformed, a straw or other rod-like object 3 is stored in the recess, and this belt-like film 2 is laid flat. Cover each strip-shaped film 1 with another strip-shaped film 1, and weld each strip-shaped film 1, 2 to the flat overlapping surface between the protrusions over the entire width, and Weld the edges 5, 5 to 2
The surface of the flat strip-shaped film 1 side of a continuous package D of straws and other stick-like objects, in which a large number of straws and other stick-like objects 3 are enclosed in parallel and at regular intervals between the strip-like films 1 and 2. Then, in the same manner as described above, a hot melt having a melting point lower than that of the films 1 and 2 is applied to the left and right edges 5 and 2 of the films.
A bead-shaped hot-melt adhesive 4 is applied to a pair of band-shaped areas 4, 4 with a predetermined width b spaced apart from each other by a predetermined distance a parallel to 5.
A is applied in a staggered pattern to form the adhesive part.
This is cut into pieces by a predetermined machine and glued to the container A as a single package C. In this case, when winding up the ladder-like continuous package D containing the stick-shaped object (straw) 3 into a roll, use a well-known wheel-type coating machine and a doctor knife, etc., onto the film containing the hot melt. Apply it in a continuous strip in a staggered manner in a uniform bead shape, cut it off one by one using a stick applicator, place it on container A, heat the hot melt with a heater to reactivate it, and stick it on container A. do. When attaching the above package C to container A, package C shown in Fig. 2 is attached.
As shown in the enlarged plan view of the adhesive coated part of the package C, a pair of rectangular parts 6, 6 to be heat-bonded on both sides of the part in which the rod-shaped object (straw) 3 is enclosed are coated with a pair of adhesives of the package C. A heating member (heater, not shown) equipped with a heating section having the same shape as the rectangular section 6 is used to press the two surfaces of the film on the protrusion side at the corresponding locations in each of the areas 4, 4 to a temperature at which the film will not be thermally deformed. When the bead-shaped hot melt 4a is heated, the hot melt is melted and reactivated, and the package C is stuck to the container A. FIG. 5 is a perspective view showing an example of the usage state of the package according to the present invention, in which a package C in which a stick-shaped object (straw) 3 is stored in a container A containing juice, milk, etc. is placed on the side of the container A. This shows the state in which the pair of rectangular parts 6, 6 on both sides of the protruding part of the package C are pressed and heated at the upper and lower corresponding positions at predetermined positions in the diagonal direction, and H indicates that the straw is inserted into the container. It is a sealed hole for.
At the time of pasting, compared to spraying hot melt from a nozzle of a conventional adhesive sprayer (hot melt gun) onto the adhesive point where the package C of the container A is to be pasted, the method of the present invention is more effective. If a packaged product is used, the amount of hot melt can be reduced, and it is possible to apply a thin layer onto the packaged product. That is, when spraying hot melt onto a container using a hot melt gun, for example, 50 to 60 mg of hot melt was required for one package of straw, but when coating the package in advance, using a ladder or continuous package D as an example. If you take it, straw 1
It is economical with only 20 mg per book package. This is because the hotmelt is directly reactivated by a heater when the package is attached to the container, so the hotmelt dots, which are similar to traditional sprayed small-diameter raised adhesives, have a protective layer to maintain their molten and activated state. This is because you don't have to expect heat.

[Effect of idea]

As is clear from the above description, if the packaging for straws and other stick-like objects according to the present invention is used,
As mentioned above, it is economical because the amount of hot melt used is small when pasting on containers, and the straw pasting machine does not require a hot melt pasting machine for melting and spraying the hot melt, and can be pasted by simple heating. This has the advantage of reducing the cost of the equipment because it only requires a coating device, and since no fluid is used, such as by using a sprayer, the equipment does not get dirty and is easy to maintain. This makes management easier. Also,
This eliminates the drawbacks of conventional pasting devices, such as the fact that if the spraying accuracy from the nozzle is poor, the package may come off the adhesive part of the container, making it impossible to achieve the intended purpose. In addition, if the hot melt is applied in a bead shape in a staggered manner as in the example, for example, if the package is a continuous package in the form of a ladder, the ladder will be rolled up into a roll and delivered to the customer. There is a concern about sticking, but when applying in a beaded staggered manner as in the present invention, there is no such fear because the contact area is reduced. As mentioned above, the packaging for straws and other stick-like objects according to the present invention is easy to attach to containers, avoids increasing the cost of packaging attachment equipment, reduces dirt on the equipment, and facilitates maintenance of the equipment. This method has many advantages, such as being easy to apply and always achieving uniform and high quality adhesion.
