[First Embodiment]
As illustrated in FIGS. 1A to 1B, the first embodiment includes a resin outer plug 30, a resin inner plug 20, and a glass container 12 having a groove portion 14 a in the shed 14. A glass container for perfume 10 comprising a resin inner plug 20 that is press-fitted from the top surface 14c side of the mouth 14 of the glass container 12, and sandwiched from the outer wall side and the inner wall side across the mouth 14; It has a projection 20e that engages with the groove 14a, has an opening 20g that penetrates into the glass container 12, and is press-fitted into the opening 20g of the resin inner plug 20 into the resin outer plug 30 or The perfume glass container 10 is provided with a long object 32 that is screwed and reaches the inside of the glass container 12.
Hereinafter, it will be described in detail by dividing into constituent materials.

1. Glass container (1) Basic form The form of the glass container is not particularly limited, and depending on the application, a pot type glass bottle, a bottleneck type glass bottle, a rectangular glass bottle, a cylindrical glass bottle, and a deformed glass bottle A rectangular glass box, a cylindrical glass box, an irregular glass box, and the like.
Therefore, as a basic form of the glass container, as shown in FIGS. 2A to 2C, the glass container 12 has a predetermined outer shape, and is configured from the top 14, the body 16, and the bottom 18 from above. It is preferable that the shed 14 has a groove 14a described later.

That is, if it is the glass container 12 shown to Fig.2 (a), it is a pot type | mold, and while an internal volume can be made comparatively large and an outer surface is smooth, the decoration to the said surface is carried out. The effect that it becomes easy can be acquired.
Moreover, if it is a glass container 12a shown in FIG.2 (b), it is a pot type | mold, and while an internal volume can be made comparatively large, since the outer surface has the predetermined unevenness | corrugation 12a 'in the vertical direction, The effect that design property improves can be acquired.
Furthermore, if the glass container 12b shown in FIG. 2C is a pot type, the inner volume can be made relatively large, and the outer surface has diamond cut-like irregularities 12b ′. The effect that design property improves can be acquired.

Moreover, although it can change suitably also about the height (it may be called A1) of a glass container, it is preferable to make the height of this glass container into the value within the range of 20-100 mm normally. .
The reason for this is that when the height of the glass container is less than 20 mm, the internal volume becomes excessively small, and the perfume capacity may be excessively decreased.
On the other hand, if the height of the glass container exceeds 100 mm, it may not be suitable for a glass container for perfume.
Therefore, the height of the glass container is more preferably set to a value within the range of 30 to 80 mm, and further preferably set to a value within the range of 40 to 60 mm.

(2) Groove part Moreover, as shown to Fig.2 (a)-(c), in the glass container 12, it has the groove part 14a in the mouth 14, It is characterized by the above-mentioned.
That is, by providing such a groove portion 14a, the adhesion between the protrusion 20e of the resin inner plug 20 that engages with the groove portion 14a is improved, so that perfume external leakage can be effectively prevented.

Here, the form of the groove provided in the shed is not particularly limited, but the width of the groove is preferably set to a value within the range of 0.1 to 8 mm.
The reason for this is that when the width of the groove is less than 0.1 mm, the adhesion between the resin inner plug becomes insufficient, and external leakage of the perfume may not be effectively prevented. .
On the other hand, if the width of the groove exceeds 8 mm, the adhesiveness with the resin inner plug becomes insufficient, and external leakage of the perfume may not be effectively prevented.
Therefore, the width of the groove provided in the mouth of the glass container is more preferably set to a value within the range of 0.5 to 5 mm, and further preferably set to a value within the range of 1 to 3 mm.

Moreover, it is preferable to make the depth of a groove part into the value within the range of 0.1-5 mm normally.
The reason for this is that when the depth of the groove is less than 0.1 mm, the adhesion between the resin inner plug becomes insufficient, and external leakage of the perfume may not be effectively prevented. is there.
On the other hand, if the depth of the groove exceeds 5 mm, it is insufficient on the contrary, and external leakage of the perfume may not be effectively prevented.
Therefore, the depth of the groove provided in the mouth of the glass container is more preferably set to a value within the range of 0.3 to 3 mm, and further preferably set to a value within the range of 0.5 to 2 mm.
In addition, the number of such groove portions can also be determined in consideration of the adhesion between the mouth of the glass container and the resin stopper, the mounting ability of the resin stopper, etc. At least one, more specifically, 2 to 4 is preferable.

(3) Kind Moreover, it does not restrict | limit especially also about the kind of glass which comprises a glass container, For example, soda-lime glass, borosilicate glass, lead glass (crystal glass), quartz glass, phosphate glass, etc. Can be mentioned.
And since a more accurate internal protrusion can be formed easily, it is more preferable to comprise a glass container by using soda glass as a main component.

Moreover, although it is preferable to use a colorless transparent glass as a glass material which comprises a glass container, it is also preferable to use colored transparent glass and colored translucent glass.
When colorless and transparent glass is used, the color of the perfume contained in the glass container for perfume can be sufficiently recognized outside, and the color of the perfume can be clearly recognized by utilizing the internal reflection of light. .
On the other hand, when colored transparent glass or colored translucent glass is used, a perfume glass container with better decorativeness can be obtained by taking into account the color of the perfume using internal reflection of light.

(4) Manufacturing method The manufacturing method of the glass container is not particularly limited, and may be any of a blow and blow method, a press and blow method, a one press method, and the like.
However, it is more preferable to employ the blow-and-blow method because the glass container is relatively small and a large number of glass containers can be stably molded from one mold at a time.

Here, with reference to FIG. 3 (a)-(d), an example (blow and blow method) of a manufacturing method of a glass container is demonstrated concretely.
First, as shown in FIG. 3 (a), a rough mold 43 and a funnel 40 are prepared, and after being arranged at a predetermined place, a molten glass take-out port is provided via the funnel 40 arranged on the rough mold 43. A molten glass lump (gob) 50 is inserted into the rough mold 43 from (not shown).
Next, as shown in FIG. 3 (b), a baffle 54 is installed above the funnel 52, and air is inserted using a blowing port 55 of the baffle 54 to form a soot by so-called blow molding. To do.

Next, as shown in FIG. 3 (c), the baffle 54 is temporarily removed from the rough mold 43, the funnel 52 is removed, the baffle 54 is placed directly with respect to the rough mold 43, and the parison 59 is Blow molding.
Further, as shown in FIG. 3 (d), the finishing mold 64 and the bottom 66 are installed in a predetermined place, and the parison is disposed in the finishing mold 64 with the direction of the mouth being reversed, and then the mouth side The glass container 12 used for the glass container for perfume can be blow-molded by inserting air from the nozzle 60 and further cooling the tip of the bottom 66 with air from the inside.

2. Resin outer plug (1) shape The shape of the resin outer plug 30 is not particularly limited. For example, as shown in FIG. 1 or FIG. And the outer plug main body 31 having a circular shape (including an ellipse and an oval shape) and a long object 32 extending vertically below the center of the circle. It is preferable that it is comprised from these.
That is, when a long product of the resin outer plug is press-fitted into the opening of the resin inner plug, the long product can effectively suppress external leakage of the perfume.
On the other hand, when the long product is detached from the opening of the resin inner plug, the perfume in the glass container can be easily taken out through the opening of the resin inner plug.

Further, regarding the shape of the resin outer plug, as shown in FIG. 1 and FIG. 4A, a protrusion 36 that contacts the ceiling wall 20c, which is the upper surface of the resin inner plug 20, below the resin outer plug 30. Is preferably provided.
The reason for this is that by providing such a protrusion 36 at a predetermined location, the adhesion between the resin outer plug 30 and the resin inner plug 20 is improved, and not only the long object 32, This is because the protrusion 36 can also reduce the external leakage of the perfume. That is, a seal is held between the long object 32 of the resin outer plug 30 and the opening of the resin inner plug 20, and the protrusion 36 of the resin outer plug 30 and the resin inner plug 20 are sealed. The ceiling wall 20c is sealed.
Further, by providing such a projection 36, the tip of the long object 32 (point A in the figure) of the resin outer plug 30 in FIG. This is because the creepage distance to the outer location (point B in the figure) can be increased.
Therefore, since the length of the portion where the capillary phenomenon occurs can be increased, the external leakage of the perfume caused by the capillary phenomenon can be further reduced.

Then, as shown in FIGS. 1 and 4A, when the protrusion 36 is provided below the outer plug main body 31 having a circular planar shape, the elongated object 32 is positioned adjacent to the protrusion 36. At the base of the circular groove portion 38 is formed when viewed in plan.
Therefore, as shown in FIG. 1, when the resin outer plug 30 is placed on the glass container 12 via the resin inner plug 20, between the resin outer plug 30 and the resin inner plug 20, In addition, when viewed in plan along the root of the long object 32, a circular chamber 38 is formed.
Therefore, by forming such a small chamber 38 in the middle of the place where the capillary phenomenon occurs, the creepage distance from the point A described in FIG. 4A to the point B can be increased. In addition, the occurrence of capillarity itself can be suppressed due to pressure, and as a result, external leakage of perfume can be further reduced.

Further, as shown in FIG. 1 and FIG. 4A, it is preferable to provide a knob portion 34 protruding outward along the outer peripheral portion of the resin outer plug 30.
The reason for this is that by providing such a knob portion 34, the lower portion of the knob portion 34 can be gripped, and hence the resin outer plug 30 can be easily attached and detached, so that the perfume glass container 10 can be handled. This is for further improvement.
That is, when the lower part of the point C described in FIG. 4A is gripped and the resin outer plug 30 is lifted upward or the screw is turned in the direction of unscrewing, first, the position of the point B is It lifts and the adhesive force between the resin inner plug 20 decreases.
Next, when the resin outer plug 30 is further lifted upward or the screw is turned in the direction of unscrewing, the ceiling wall 20c and the inclined surface of the resin inner plug 20 are used on the principle of the long object 32 as a fulcrum. The engagement between 20d 'and the protrusion 36 that contacts them can be easily released, and the adhesion between the resin inner plug 20 is further reduced.
Then, when the resin outer plug 30 is further lifted upward or the screw is turned in the direction of unscrewing, the long object 32 gradually rises along the opening 20g of the resin inner plug 20 and is made of resin. It will be easily detached from the inner plug 20.

  The vertical cross-sectional shape of the knob portion 34 shown in FIGS. 1 and 4 is generally a tongue shape that narrows toward the tip, but other than a flat plate shape, a trumpet shape that thickens toward the tip conversely. It may be.

(2) Kind Moreover, it does not restrict | limit especially about the kind of resin which comprises a resin-made outer stopper, Various resin can be used. Therefore, for example, at least one of polypropylene resin, polyethylene resin, polycarbonate resin, polyester resin, acrylic resin, polyurethane resin, epoxy resin, phenol resin, silicone resin, and the like is preferable.
And it is more preferable that the main component of the resin constituting the resin outer plug is a polypropylene resin (PP resin).
This is because a polypropylene resin is a general-purpose resin, so it is inexpensive and easily available.
In addition, if it is a polypropylene resin (PP resin), compared to polyethylene resin (PE resin) or the like, not only has a high hardness, it is excellent in durability, and a resin outer plug made of polypropylene resin, This is because the inner plug made of polyethylene resin or the like is easily adhered.

(3) Hardness Moreover, it is preferable to usually set the hardness of the resin outer plug (Rockwell hardness (R-scale) measured according to JIS K7202) to a value within the range of 80 to 120.
The reason for this is that by adopting such hardness, in relation to the same hardness of the resin inner plug, the long product of the resin outer plug is press-fitted into the opening of the resin inner plug, which is excellent. This is because the adhesiveness can be obtained.
Therefore, the hardness of the resin outer plug is more preferably set to a value within the range of 85 to 115, and further preferably set to a value within the range of 90 to 110.
The hardness of the resin outer plug is determined by the kind of polypropylene resin that is a constituent resin of the resin outer plug, the average weight molecular weight, crystallinity, or the filler or surface treatment material that may be blended in the constituent resin. It can adjust by changing a kind and a compounding quantity suitably.

(4) Long product Since the perfume can be easily taken out and can be easily applied to the skin or the like, as shown in FIG. 4 (a), the resin outer plug 30 has a predetermined long product 32. It is characterized by having.
Here, it is preferable to set the length (L1) of the long object to a value within the range of 10 to 80 mm.
This is because it may be difficult to take out the perfume when the length of the long product is less than 10 mm.
On the other hand, when the length of the long product exceeds 80 mm, the amount of perfume taken out may be excessively increased.
Therefore, it is more preferable to set the length of the long product to a value within the range of 20 to 70 mm, and even more preferable to set the value within the range of 30 to 60 mm.

Moreover, it is preferable to make the diameter (L2) of a long thing into the value within the range of 0.1-10 mm.
The reason for this is that when the diameter of the long product is less than 0.1 mm, the mechanical strength of the long product may be significantly reduced.
On the other hand, when the diameter of such a long product exceeds 10 mm, the adhesiveness with the resin inner plug becomes insufficient, and perfume external leakage may easily occur.
Therefore, the diameter of the long object is more preferably set to a value within the range of 0.5 to 8 mm, and further preferably set to a value within the range of 1 to 5 mm.

In addition, considering the vertical cross-sectional shape of the opening in the resin inner plug, it is preferable that the tip of the long object provided in the resin outer plug is tapered.
That is, although not shown, the vertical cross-sectional shape of the opening in the resin inner plug is a tapered shape that narrows downward, and as shown in FIG. 5A, the length provided in the resin outer plug 30a. It is preferable to make the front-end | tip part of the scale-shaped object 32a into the taper shape which becomes narrow toward the downward direction.
The reason for this is that by configuring the resin inner plug and the resin outer plug in this manner, it is easy not only to remove and remove the long object from the resin outer plug from the opening of the resin inner plug, This is because adhesion between the outer plug and the resin inner plug is improved.

And as shown in FIG.5 (b), while making the front-end | tip part of the elongate thing 32b provided in the resin-made outer stoppers 30b into the taper shape which becomes narrow toward the downward direction, the front-end | tip of the elongate thing 32b It is preferable to provide a screw part 32b 'in the part.
The reason for this is that, by making the long product of the resin outer plug into a taper / screw configuration, it is possible to detach it simply by rotating the long product of the resin outer plug. This is because the adhesion between the resin outer plug and the resin inner plug is further improved.

In addition, any one of a spongy projection, a heart-shaped projection, a bowl-shaped projection, a spatula-shaped projection, a spiral-shaped projection, and a ring-shaped projection is provided at the end of the long object. It is preferable.
The reason for this is that such a configuration of the tip can facilitate the handling of the perfume and enhance the design effect of the glass container for perfume.

  More specifically, as shown in FIG. 6 (a), if the shape of the tip 32 'of the long object is a spongy protrusion, even if it is a considerable amount of perfume, it is scooped out. Thus, it can be reliably taken out of the glass container and can be easily applied to a predetermined place (skin). In addition, a certain amount of perfume can always be taken out by simply changing the volume (dentation) of the spongy projection.

In addition, as shown in FIG. 6 (b), if the shape of the long end 32 ′ is a heart-shaped protrusion, the design effect is high, and a predetermined amount of perfume is taken out and a predetermined location of the pinpoint is obtained. Even (skin) can be reliably applied.
In addition, as shown in FIG. 6C, if the shape of the tip portion 32 'of the long object is a bowl-shaped protrusion, even if a considerable amount of perfume is attached, it is easy to adhere to the surroundings, and the predetermined It can be easily applied to a place (skin).
Further, as shown in FIG. 6 (d), if the shape of the tip 32 'of the elongated object is a spatula-like protrusion, even if it is a considerable amount of perfume, And can be easily applied to a predetermined place (skin).

Further, as shown in FIG. 7A, if the shape of the tip 32 'of the long object is a spiral protrusion, the design effect is high, and even a considerable amount of perfume adheres to the periphery. It can be easily applied to a predetermined place (skin).
Further, as shown in FIG. 7B, if the shape of the tip 32 ′ of the long object is a ring-shaped protrusion, even if a considerable amount of perfume is easily attached to the periphery, It can be easily applied to (skin).
Furthermore, as shown in FIG. 7 (c), if the shape of the tip 32 'of the long object is a composite protrusion of a hook-like protrusion and a helical protrusion, the design effect is high and Even if it is a quantity of perfume, it becomes easy to adhere to the circumference | surroundings of a composite protrusion, and it can apply easily with respect to a predetermined place (skin).

(5) Manufacturing method The manufacturing method of the resin outer plug is not particularly limited. For example, an injection molding method, a mold molding method, an extrusion molding method, or the like can be employed.

3. Shape of Resin Inner Plug (1) Also, the shape of the resin inner plug is not particularly limited. However, as shown in FIG. It is preferable that when it is press-fitted from the top surface 14c side and the vertical cross-sectional shape is viewed from the lateral direction in that state, it becomes substantially U-shaped.
The reason for this is that by making the resin inner plug into such a shape, when it is press-fitted across the mouth of the glass container, it is sandwiched from the outer wall side and the inner wall side so that the mouth of the glass container can be easily This is because it can be pressed.

Then, as shown in FIG. 8A, which is a vertical sectional view of the resin inner plug 20, a groove portion 14a provided in the mouth 14 of the glass container 12 on the outer wall 20a and the inner wall 20b of the resin inner plug 20. , 14b is preferably provided with projections 20e and 20f for engaging with 14b.
The reason for this is that by using a resin inner plug having such a protrusion, the adhesion between the resin inner plug and the resin outer plug is improved, and as a result, external leakage of perfume is effectively suppressed. This is because it can be done.

Moreover, as shown in FIG. 1A or FIG. 8A, it is preferable that the resin inner plug 20 has an opening 20 g penetrating into the glass container 12.
The reason for this is that by providing such an opening, it is possible to press-fit a long object provided in the resin outer plug and effectively suppress external leakage of perfume.
On the other hand, it is because a predetermined amount of perfume can be taken out by removing a long object provided in the resin outer plug from such an opening.

Further, as shown in FIG. 1 (a) or FIG. 8 (a), the resin inner plug 20 is provided with a protruding portion 20d having an inclined surface 20d 'inclined downward and outward on the ceiling wall 20c. preferable.
This is because when the resin outer plug 30 is pressed downward, the protrusion 36 of the resin outer plug 30 engages with the protrusion 20d provided on the ceiling wall 20c, and then slides on the inclined surface 20d ′. However, it is because it is locked at a predetermined position.
In addition, by appropriately adjusting the height of the protruding portion 20d provided on the ceiling wall 20c, the degree of engagement with the protruding portion 36 of the resin outer plug 30 can be changed, and capillary action can be reduced. This is because the size of the small chamber 38 for suppression can be changed as appropriate.
In addition, although it does not restrict | limit especially also about the angle of inclined surface 20d 'of the resin inner stopper 20, Usually, it is preferable to set it as the value within the range of 20-60 degrees with respect to a perpendicular direction.
Then, as shown in FIG. 1 (a), on the side surface of the protrusion 36 of the resin outer plug 30 so that it can be engaged with the inclined surface 20d 'of the resin inner plug 20 with a large area and without a gap. However, it is preferable to provide an inclined surface.

The adhesiveness and the adhesiveness with the glass container can be further improved.

(3) Hardness Moreover, it is preferable that the hardness of the resin inner plug (Rockwell hardness (R-scale) measured in accordance with JIS K7202) is usually set to a value in the range of 50 to 72.
The reason for this is that, when such a hardness is used, when a long product of the resin outer plug is pressed into the opening of the resin inner plug in relation to the same hardness of the resin outer plug. This is because excellent adhesion can be obtained.
Therefore, the hardness of the resin inner plug is more preferably set to a value within the range of 55 to 70, and further preferably set to a value within the range of 58 to 68.
The hardness of the resin outer plug is determined by the kind of polyethylene resin that is a constituent resin of the resin outer plug, the average weight molecular weight, crystallinity, or the filler or surface treatment material that may be blended in the constituent resin. It can adjust by changing a kind and a compounding quantity suitably.
