DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a container for packaging cosmetics such as cosmetic creams, milky lotions, hair styling products and the like, or a cap for the container. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container or cap provided with a ring-shaped border such as a color, and a method and apparatus for forming a border on a shoulder of the container or the cap.

[0002]

2. Description of the Related Art For example, a relatively wide-mouthed container for packaging a cosmetic cream is generally manufactured by injection molding using a synthetic resin as a raw material. There is a disadvantage that the decorativeness is low. Therefore, in order to give the container a gorgeous and high-grade feel, a ring-shaped border made of gold or silver metal is applied to the shoulder of the container.

Conventionally, as a means for forming a ring-shaped edge on the shoulder of the container, as shown in FIG.
The ring body 42 to be fitted to the shoulder 41a is manufactured by sheet metal processing of a thin metal plate, and the ring body 42 is plated with gold plating, silver plating, or the like, and then the ring body 42 is coated with a hot melt adhesive. It is attached to the shoulder 41a of the container 41, or the ring 42 is manufactured by injection molding using a synthetic resin as a material, and a metal such as gold or silver is coated on the surface of the synthetic resin ring 42. is deposited, the shoulder 41 of the container 41 of the ring member 42 by a hot-melt adhesive or heating preparative seal method
a (the plating layer or the metal deposition layer of the ring body 42 is indicated by reference numeral 42a).

On the other hand, in a synthetic resin cap 43, a ring-shaped border made of a metal color is formed on a shoulder 43a. In this case, as shown in FIG. A transfer film 44 is used in which a colored transfer material is attached to one side of the film. The transfer material of the transfer film 44 is attached to the cap 43 by pressing with a hot platen 45, and then the base of the transfer film 44 is used. The film is peeled off from the transfer material adhered to the cap 43, so that the transfer material of the transfer film 44 is removed from the cap 43.
The thermal transfer method of sticking to the shoulder portion 43a is adopted.

[0005] Rotation of this case, the method shown in FIG. 25 (a), the cap 43 is fixed to the jig 46 to the axis O1 around
One was that, grooves 4 for fitting the the shoulder portion 43a of the cap 43
The roller-shaped hot plate 45 formed with 5a is rotated around a rotation axis O2 intersecting with the rotation axis O1 of the cap 43, and the transfer film 44 is attached to the shoulder 43a of the cap 43 by the roller-shaped hot plate 45. It is designed to hold down.

In FIG. 25A, the transfer film 4
Reference numeral 4 is formed in a belt shape, and is fed out in a direction orthogonal to the paper surface. The transfer material is provided on the lower surface of the transfer film 44. On the other hand, in the method shown in FIG. 25B , a plate-like heating plate 45 formed in an arc shape in a plan view is disposed below a transfer path for feeding out a wide transfer film 44 in a horizontal posture along a longitudinal direction. On the other hand, a jig (not shown) is provided above the transfer path of the transfer film 44 so as to hold the cap 43 in an inclined posture. By rotating as shown,
The cap 43, is rolled the shoulder 43a in a state of abutting on the transfer film 44, I hereinafter, the shoulder 4 of the cap 43
The transfer material of the transfer film 44 is stuck to 3a.

In FIG. 25B, the transfer material is provided on the upper surface of the transfer film 44. In the case where a ring-shaped border is formed on the body of the container 41, the transfer film 4 may be used.
The thermal transfer method using No. 4 is used.

[0008]

As shown in FIG. 24,
The ring 42 made of a thin metal plate or a synthetic resin is
The means for affixing to the shoulder portion 41a is such that a metal-colored border is formed in a state where the inner circumference and the outer circumference are continuous without any level difference (that is, the seam
This has the advantage that it can be formed in a state where the periphery is continuous in a non-existent state) , but on the other hand, it takes a lot of time and labor to process the ring body 42 and manufactures various types of ring bodies 42 according to the size of the container 41. Because of this, there is a problem that the manufacturing cost is significantly increased.

Further, since the ring body 42 is thick, a step is generated between the inner peripheral edge and the outer peripheral edge of the ring body 42 and the surface of the container 41. In this regard, in the thermal transfer method of FIG. 25 , since the transfer film 44 is inexpensive, and one type of transfer film 44 can be used to border many types of caps 43, the manufacturing cost can be significantly reduced. Therefore, it is considered that if this thermal transfer method is applied to the container 41, the container 41 having the shoulder portion 41a bordered can be manufactured at low cost. Further, since the transfer material is extremely thin in the form of a foil, there is no problem of beauty due to the steps.

However, in the case where the means for edging the shoulder portion 43a of the cap 43 by the thermal transfer method is simply applied to the container 41 as it is, in any of FIGS. The hot plate 45 is blocked by the mouth 41b.
Cannot be pressed against the shoulder 41a, and therefore, it has not heretofore been performed to form a metal-colored border on the shoulder 41a of the container 41 by the thermal transfer method.

In other words, conventionally, although the thermal transfer method was known to be inexpensive, the problem that the mouth 41b was obstructed could not be overcome, so that the shoulder 41a of the container 41 was bordered by the thermal transfer method. Therefore, a ring 42 made of a metal plate or a synthetic resin is stuck as shown in FIG. In addition, FIG. 2
In the case where the shoulder 43a of the cap 43 is edged by a thermal transfer method by means such as 5 , the transfer film 4 formed in a belt shape is used.
Since the transfer material of No. 4 is sequentially attached, the start and end of the border formed of the transfer material are shifted in the width direction, and a step is generated between the inner circumference and the outer circumference, so that the appearance may be deteriorated. The point was also a problem.

According to the present invention, a ring-shaped border can be formed on a shoulder of a container by a thermal transfer method using a transfer film, and a ring-shaped border is formed on a shoulder of a cap as in the prior art. The purpose is to make the application beautiful.

[0013]

In order to achieve the above object, according to the present invention, in a container having an upward opening or a cap having a downward opening, the container is provided with a shoulder which connects an outer peripheral surface and an upper surface thereof. Alternatively, a transfer material in a foil shape having a color different from that of the cap is stuck in a continuous shape as if punched in a ring shape, and is adhered. "

As a preferred method for forming a border of the container or the cap according to the first aspect, as described in the second aspect, "a foil-like transfer material is bonded to one surface of a synthetic resin base film. The transfer film is placed on the shoulder of the container or cap so that the transfer material is in close contact with the container or cap, and in that state, the transfer film is pressed by a ring-shaped hot plate overlapping the shoulder. Then, the transfer material of the transfer film is adhered to the shoulder of the container or cap in the same ring shape as the hot plate, and then the hot plate and the transfer film are separated from the container or cap, and the base film of the transfer film is removed. Peel off from the transfer material adhered to the container or cap. "

Further, as an edge forming apparatus suitable for manufacturing the container or the cap according to the first aspect, as described in the fourth aspect, "the transfer film is horizontally disposed above the support holding the container or the cap. A ring-shaped hot plate for attaching the transfer material of the transfer film to a shoulder of a container or a cap is disposed above the clamp mechanism; Either or both of the support and the support are attached to a vertical movement mechanism so as to be vertically movable. "

The "transfer material" in the present invention may be a metal foil such as an aluminum foil or a gold foil, a synthetic resin film coated with a metal such as aluminum by appropriate means such as vapor deposition, or a synthetic resin colored with ink or the like. Various structures such as a film or a film obtained by laminating a protective layer or the like thereon can be used.

[0017]

According to the first aspect of the present invention, a transfer material is provided.
By sticking in a continuous shape as if punched in a ring shape, the inner and outer circumferences of the ring-shaped rim can be made to appear in a continuous state without a step, improving the decorative effect Ru can increase the commercial value Te. In particular, when applied to rimming the shoulder of the container, the transfer material is thin and there is no step with the surface of the container. is there.

According to a second aspect of the present invention, when the transfer material of the transfer film is transferred to a container or a cap by using a ring-shaped hot plate to perform the edging, the edging remains in the shape of the hot plate. Alternatively, since the cap is formed on the cap, the ring-shaped edging in which the inner periphery and the outer periphery are continuous without a step can be extremely easily and reliably performed. Therefore, there is an effect that an edged container or cap with high decorative effect and high commercial value can be manufactured at low cost.

Further, by setting the shape of the hot plate to various shapes, there is an effect that various shapes of edging can be easily applied to containers or caps of various cross-sectional shapes. Further, the fourth aspect is obtained by capturing the configuration of the second aspect from the aspect of the apparatus, and has the same effect as the second aspect. In this case, since the transfer material is transferred to the container or the cap in a state where the transfer film is clamped by the clamp mechanism, there is an advantage that the border can be formed in a beautiful state without wrinkles.

Further, when at least the portion of the hot platen which comes into contact with the container or the cap is made of heat-resistant rubber, the hot plate is elastically deformed and comes into close contact with the shoulder of the container or the cap. There is an effect that the border can be reliably applied regardless of the manufacturing error of the container or the cap.
Furthermore, as described in claim 6, when a pressing member for pressing a portion of the film inside the hot plate is provided,
Since the transfer film can be reliably prevented from being displaced when pressed by the hot plate, the border can be more beautifully formed. In particular, when the hot plate is made of heat-resistant rubber as in claim 5, the hot plate is in close contact with the outer surface of the pressing body,
From <br/> the outer circumferential surface of the pressing member is Ru appear as the inner peripheral line of edging, heating plate is able to form a sharp inner circumference of the line-up also the edges a rubber is more suitable is there.

I try to grasp. A nut 23 is screwed onto each of the columns 19 to prevent the clamp bodies 11a and 11b from coming off.

Therefore, the transfer film 10 can be pushed downward while the transfer film 10 is clamped by the clamp mechanism 11. As shown in FIGS. 6 and 9, holes 24 having a diameter larger than that of the hot platen 15 are formed concentrically with the hot platen 15 in the upper and lower clamp bodies 11a and 11b. A ring 25 made of an elastic material such as an O-ring is mounted concentrically with the hole 24. In this case, the annular groove 2 for fitting the ring body 25
6 are formed into two large and small strips so that ring bodies 25 having different diameters can be mounted.

As shown in FIG. 6, the hot platen 15 has a downwardly opening substantially cup-shaped main body portion 15a fixed to the heater 14 by screws, and a ring fixed to the lower end surface of the main body portion 15a so as not to be detachable. And a contact portion 15b in the shape of
The main body 15a is made of a metal having good heat conductivity such as steel or aluminum, while the contact portion 15b is made of a heat conductive elastic material such as heat-resistant rubber so that the contact portion 15b is in close contact with the shoulder 1a of the container 1. It is formed in a simple cross-sectional shape. Therefore, the heat of the heater 14 is transmitted to the hot platen 15.

As shown in FIG. 6, a heat radiating hole 15c is formed in the main body 15a of the hot platen 15. The hot plate 1
In the space of the main body 15a in FIG.
6 is inserted so as to be movable up and down. This pressing member 16
Is held by a rod 27 so as not to be disengaged downward, and is urged downward by a spring 28. Pressing member 1
Reference numeral 6 is made of a material having low thermal conductivity such as bakelite, and is set so as to project slightly downward from the lower surface of the hot platen 15.

On both left and right sides of the heater 14, two pressing rods 29 are provided to project downwardly so as to come into contact with the upper clamp body 11a by the downward movement of the header 12. A slider 29 a is slidably and slidably fitted upward at the lower end of each pressing rod 29, and urges the slider 29 a downward by a spring 30. The pressing rod 29 may be attached to the header 12.

The spring force of the spring 30 fitted on the pressing rod 29 is set to be larger than the spring force of the spring 21 supporting the clamp mechanism 11, and the spring 22 is made of an elastic body.
The elastic restoring force of this (this may be a spring) is set to a value smaller than the spring force of the spring 21 supporting the clamp mechanism 11. The lower clamp body 11a or the lower machine frame 8b
Further, a stopper (not shown) for defining a lower limit of the lowering of the clamp mechanism 11 may be provided.

The transfer film 10 is wound in a roll shape and is configured to be transported in a longitudinal direction by a feed mechanism (not shown). (Not shown), and a hole 10a to be fitted to the mouth 2 of the container 1 is formed every time the container 1 is fed out by a predetermined size. As shown in FIG. 7, the transfer film 10 is a base film 10 'made of a synthetic resin film such as polyethylene terephthalate.
A transfer material 5 similar to that of FIG.
By making the bonding strength between the release layer 5a and the base film 10 'smaller than the bonding strength of the adhesive layer 5f to other members by heat sealing, the transfer material 5 can be transferred to various members. It was made. Base film 1
An antistatic layer 10 ″ is provided on the upper surface of 0 ′.

In the above arrangement, the container 1 mounted on the support 9 is positioned directly below the hot platen 15 and the transfer film 10 is fed so that the holes 10a thereof are concentric with the container 1 and the hot platen 1. In that state, the air cylinder 13
Is driven to lower the header 12. Then, FIG.
As shown in (2), when the pressing rod 29 comes into contact with the upper clamp body 11a, the collar 22 made of an elastic body is compressed, and the transfer film 10 is clamped by the clamp mechanism 11, and in this state, the entire clamp mechanism 11 is The transfer film 10 descends, and the inner peripheral edge of the hole 10 a of the transfer film 10 contacts the shoulder 1 a of the container 1.

Next, as shown in FIG. 12A, the inner peripheral edge of the transfer film 10 is pressed against the upper surface of the shoulder 1a of the container 1 by the pressing member 16, and in this state, as shown in FIG.
To indicate Suyo in 2 (b), the transfer film 10 by the heating plate 15
Is pressed against the shoulder 1 a of the container 1, and the portion of the transfer material 5 of the transfer film 10 that overlaps the heating platen 15 is joined to the shoulder 1 a of the container 1.

Then, when the header 12 is raised, the transfer film 10 is separated from the container 1 while being clamped by the clamp mechanism 11, so that the base film 10 'of the transfer film 10 is transferred to the transfer material 5 bonded to the container 1. From the container 1
The transfer material 5 is adhered to the shoulder 1a in a ring shape to form a ring-shaped border.

Thereafter, while the transfer film 10 is intermittently fed out , the supply / removal of the container 1 and the raising / lowering of the header 12 are repeatedly performed, so that the shoulder 1a is provided with a ring-shaped border made of the transfer material 5. The container 1 can be manufactured continuously. In the rimming device 7 and the manufacturing method, the hot platen 5 only moves up and down, so that the transfer material 5 can be extremely easily attached to the shoulder 1a of the container 1 having the mouth portion 2. Therefore, the container 1 in which the ring-shaped border made of the transfer material 5 is provided on the shoulder 1a can be manufactured at low cost.

Further, the transfer material 5 from being transferred to leave <br/> container 1 of the shoulder 1a of the shape of the heating plate 15, able to form a border is no step at the inner circumference and the outer circumference The decorative effect can be improved. A portion of the transfer film 10 outside the hot platen 15 is clamped by the clamp mechanism 11, while the hot platen 15 of the transfer film 10 is clamped.
Since the inner portion is pressed against the container 1 by the pressing member 16, the transfer material 5 can be transferred while the transfer film 10 is kept taut, and therefore, the transfer is performed in a beautiful state without wrinkles. The material 5 can be attached to the shoulder 1a of the container 1.

Further, since the contact portion 15b of the hot platen 15 is made of an elastic material such as rubber, the contact portion 15b is in close contact with the shoulder portion 1a of the container 1 regardless of the dimensional error of the container 1. Even if the molding accuracy is low, the transfer material 5 can be stuck securely. In this case, since the contact portion 15b of the heating plate 15 is brought into close contact with the outer surface of the pressing member 16, it becomes a this inner circumferential edging made of the transfer material 5 appears as a sharp line, therefore, the elastic contact portions 15b Even if it is made of a body, the decorative effect can be further improved.

When the pressing member 16 is provided, as shown in FIGS. 4 and 7, the transfer material 5 of the portion 10b of the transfer film 10 pressed by the pressing member 16 is provided on the inner peripheral edge of the transfer film 10. It remains attached to the base film 10 '(the thickness in the thickness direction is exaggerated in FIG. 7, and the actual thickness of the transfer film 10 is as thin as tens to hundreds of microns). In addition, the clamping mechanism 11
If the elastic ring 25 is provided, the transfer film 10 can be firmly clamped without damaging the transfer film 10, so that there is an advantage that the transfer of the transfer material 5 in a wrinkle-free state can be more reliably performed.

In the above embodiment, the pressing member 16 is formed of a heat insulating material. However, a ring-shaped heat shield is provided between the outer peripheral surface of the pressing member 16 and the inner peripheral surface of the hot platen 15. It may be inserted. FIG. 13 shows a third embodiment in which the entire hot platen 15 is made of an elastic material such as heat-resistant rubber. In this embodiment, unlike the second embodiment, the pressing member 16 is not provided.
When the pressing member 16 is not provided, the inner diameter of the hole 10a in the transfer film 10 is slightly larger than the inner diameter of the hot platen 15, and the line of the inner diameter of the transfer film 10 is transferred to the container 1. It is preferable that the line appear as a line of the inner diameter of the transfer material 5.

FIG. 14 shows a fourth embodiment in which a disc-shaped elastic ring 25 made of rubber, sponge, or the like is attached to the lower surface of the upper clamp body 11a and the upper surface of the lower clamp body 11b. . The elastic ring 25 may be provided only on the upper clamp body 11a in order to prevent the adhesive layer 5f of the transfer material 5 from sticking to the elastic ring 25.

FIG. 15 shows a fifth embodiment in which an elastic ring 25 such as an O-ring is mounted on the upper and lower clamp bodies 11a and 11b. In the fifth embodiment, a receiving member 31 made of an elastic material such as rubber formed in a ring shape so that the container 1 is fitted tightly is mounted on the upper end of the support 9. Since the film 10 is supported by the receiving material 31, there is an advantage that the outer peripheral line of the border formed by the transfer material 5 can be sharply formed.

As clearly shown in this embodiment, the diameter of the hole 10a of the transfer film 10 may be smaller than that of the opening 2 of the container 1. Although each of the above embodiments is applied to sticking the transfer material 5 to the shoulder 1a of the container 1, the present invention is applied to the case where the shoulder 4a of the cap 4 is used as shown in FIG. The present invention can also be applied to attaching the transfer material 5 to 4a.

Further, the present invention not only the container 1 and the cap 4 of the circular shape in plan view, as shown as a seventh embodiment in FIG. 17, also apply to non-circular container 1 and the cap 4, such as a flat surface when viewed prismatic In this regard, there is an advantage that the applicable range can be remarkably improved as compared with the conventional thermal transfer method which can only be applied to a circular cap. In addition, according to the apparatus or methods of the present invention, the shape of the edging made of the transfer material 5 is not limited to simple ring shape, for example, as shown as an eighth embodiment in FIG. 18, the inner circumference or the outer circumference or both It can be formed in a wavy shape or in an intermittent state, so that the freedom in designing the border can be greatly expanded.

In the ninth embodiment shown in FIGS. 19 and 20, the clamp mechanism 11 is provided below the punch 35 and the hot platen 15.
And the lower part of the clamp mechanism 11
In the state where the transfer film 10 is clamped, the hole 10a is punched out, and the transfer film 10 is moved below the hot platen 15 while being clamped in this state, so that the transfer material 5 is transferred to the container 1. Things. With this configuration, there is an advantage that the positioning of the transfer film 5 can be accurately performed.

In this embodiment, as shown in FIG. 20, the upper clamp body 11a is pushed down by a pushing-down device 11c such as an air cylinder provided at the four corners of the lower clamp body 11b. The transfer film 10 is held by 11b. FIG. 21 to FIG.
FIG. 23 shows the tenth embodiment.

In the tenth embodiment, the transfer film 10
An endless belt 32 made of a plate material having high rigidity and being deformable and deformable, such as a thin leaf spring, is arranged below the transfer path of the transfer film 10 via a pair of pulleys 33 so as to circulate along the transfer direction of the transfer film 10. This endless belt 3
2, a large-diameter window hole 32a is formed at the same pitch as the pitch of the hole 10a of the transfer film 10, and the edge of the transfer film 10 is bonded to the upper surface of the endless belt 32 with a very weak bonding strength. Then, the transfer film 10 is forcibly transferred by the endless belt 32, and while the transfer film 10 is being transferred by the endless belt 32, the punch 10 punches the hole 10a into the transfer film 10 by the punch 35 and the die 36, and the container 1 (or The transfer material 5 is thermally transferred to the cap 4), and after the transfer material 5 is transferred, the transfer material 5 is peeled off from the endless belt 32 and fed .

The endless belt 32 has a guide rail 37
It is transported along the side without slippage. Further, the position where the transfer film 10 is stuck to the endless belt 32 is indicated by an alternate long and short dash line 34.
Indicated by. Also in this configuration, by transferring the transfer film 10 via the endless belt 32,
Since the film 10 can be transferred while absorbing the lateral displacement and the elongation in the longitudinal direction, the holes 10a can be accurately formed in the transfer film 10, and the holes 10 can be accurately formed so as to be concentric with the container 1 and the hot platen 5. Can be aligned.

In this case, the attaching portion 34 of the transfer film 10 to the endless belt 32 may be linearly extended or may be extended intermittently. The endless belt 32 may be used also as a clamp mechanism. In each of the above embodiments, the heating plate is an electric heater type. However, the heating plate according to the present invention is a concept including a sticking device of another form such as a horn in a high frequency sealing method.
