Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention accommodates a liquid fragrance in a glass container body, covers the glass container with a proper opening, and sucks it with a core material inserted into the fragrance container. A glass container used for what is called an atomizer for perfume, in which a fragrance is diffused into the outside atmosphere, or for example, a perfume in a glass container is sucked up by a pipe and sprayed, a method for manufacturing the same, and a parison molding device Is.

[0002]

BACKGROUND OF THE INVENTION Fragrances and perfumes are relatively expensive although they are consumables. Therefore, in consideration of the effective use and the economical efficiency of the fragrance and the perfume, containers and lid structures of various structures,
Atomizers have been developed and proposed.

Conventionally, as shown in FIG. 5, a glass container body of an fragrance container for containing a liquid fragrance is formed in an upward convex curved shape in which a bottom wall a is high in the center and its circumference is low. . Therefore, when the remaining amount of the liquid fragrance contained in the glass container main body becomes small, the liquid fragrance gathers at the lowest outer peripheral portion g of the bottom wall a. Therefore, if the core material b is inserted so as to face a part of the outer peripheral portion g, the fragrance contained in the glass container body can be used up to some extent. In addition, a glass container for a perfume atomizer is generally long, but since the diameter of the suction pipe is significantly smaller than the diameter of the bottom portion of the glass container, the lower end of the pipe is in this case the bottom of the glass container. The perfume is used up to some extent by facing the outer peripheral part which is lower than the center.

[0004]

However, since the outer circumference of the bottom of the glass container body for the fragrance is wide, and the outer circumference of the bottom of the glass container for perfume is wide with respect to the suction pipe, a part of it is necessary. It is difficult to suck out the entire amount of the aromatic substance remaining in the wide outer peripheral portion g by only facing the core material b and one end of the pipe. Further, the core material b and the tube inserted into the glass container body from the container mouth need to be bent to reach the outer peripheral portion g of the bottom wall a of the glass container body, and it is difficult to fit the outer peripheral portion g of the glass container body. , The rate of sucking out the remaining amount of the fragrance and the perfume is reduced due to the unfamiliarity. In addition, if the container falls or receives an external force due to other reasons, the core material or the pipe may be displaced, and it may not be possible to suck up all the remaining amount. Therefore, there is a problem in that expensive aromatic agents, perfumes and the like cannot be fully used.

An object of the present invention is to solve such a problem, and to provide a container that can fully use the contained content liquid, a manufacturing method and a parison molding apparatus that can easily and inexpensively manufacture the container. The purpose is.

[0006]

It is characterized in that a concave portion formed by thinning is provided.

In such a structure, the residual amount of the fragrance or the like in the glass container body flows into the recessed portion provided in the bottom wall of the glass container body in a limited range, and the recessed portion is almost in the center of the bottom wall. Located just below the mouth of the glass container body, the core and the tube passed through the mouth just extend just below and the one end faces the recess without bending and the recess fits well. Since it can be prevented from swinging from the proper suction position by catching with, it can absorb almost all the remaining amount of fragrance etc. in the glass container body, so expensive fragrance etc. can not be used up and discarded This can be prevented.

Also, the recess is formed by making the wall thickness thinner than the thickness of the bottom wall of the glass container body, and the lower surface of the bottom wall of the glass container body projects downward to form the recess. Since such a portion is not formed, it is possible to avoid the inconvenience that such a protruding portion is formed and the glass container body is poorly placed and is difficult to use.

According to a second aspect of the present invention, in addition to the first aspect of the present invention, the concave portion is formed to have a size substantially corresponding to the thickness of the core material that absorbs the fragrance or the like and diffuses to the outside.

With such a construction, in addition to the container for the fragrance and the like according to the first aspect of the present invention, since the recess has a size substantially corresponding to the thickness of the core material, the fragrance and the like flowing into the recess can be prevented. The remaining amount can be sucked out and used up easily.

According to a third aspect of the present invention, there is provided a method for manufacturing a container for a fragrance or the like, in which a gob placed in a rough mold and a rough mold including a baffle, a mouth mold and the like are combined with a bottom wall of a glass container body. The gob is pressed into the mouth mold by pressing with a plunger that has a protruding portion corresponding to the upward recess to be formed in the center of the parison, and the parison has a container mouth of a predetermined shape. At the same time as forming the bottom surface of the parison, the outer surface of the bottom wall of the parison is formed flat by the flat surface of the buffer in the rough mold, while the inner surface is formed in conformity with the tip surface having the protruding portion of the plunger, and the bottom surface is formed. After forming a recess in the center of the inner surface of the wall that is thinner than the surroundings due to the protrusion of the plunger, the thickness of this recess is thinner than the other parts Then blow the parison It is characterized in that the molded finish along the portion other than the vessel opening finish type of the inner surface.

In such a structure, the rough mold and the plunger can simultaneously form a recess having a thinner wall thickness than that around the bottom wall of the glass container main body without any special work during normal molding of the parison. , This recess is used to cool and harden earlier than other parts due to its thin wall thickness.After forming the parison, it is immediately blown without time lag to move to finish forming by a finishing die, and the recess is in a hardened state. Therefore, by carrying out the finish molding of other parts as usual while maintaining the shape, the container of the fragrance or the like according to claim 1 can be manufactured without causing a decrease in productivity and an increase in cost.

According to a fourth aspect of the present invention, there is provided a parison manufacturing apparatus for a container of a fragrance or the like, which comprises a rough mold including a baffle and a mouth mold, and a gob which is introduced between the rough mold and the rough mold. With a plunger forming a parison having a container mouth of a predetermined shape, the tip surface of the plunger facing the flat surface on the rough mold side forming the outer surface of the bottom wall of the parison, the bottom wall of the glass container body It is characterized in that a protrusion for forming a recess is provided at substantially the center of the inner surface.

In such a construction, the projections are provided on the front end surface for forming the inner surface having the concave portion of the bottom wall of the parison in the rough mold capable of forming the flat bottom wall outer surface of the parison of the glass container body. The parison in the method of the invention of claim 3 can be formed by a normal parison molding operation in which a plunger is inserted, and it is sufficient if the parison is subjected to the finish molding of the invention of claim 3 and the productivity is further improved. .

[0015]

BEST MODE FOR CARRYING OUT THE INVENTION A container for a fragrance, a method for manufacturing the same, and a parison molding apparatus according to the present invention will be described below with reference to one typical embodiment.

Although the present embodiment shows only the fragrance container, the present invention is applicable to general containers of various liquids for sucking up perfume or other substances for consumption as described above. As shown in FIG. 1, the glass container body 1 has an upward recess 1c formed at a substantially central portion of the inner surface of the bottom wall 1a with a thickness smaller than that of the surrounding portion 1b. The concave portion 1c is located almost directly below the container opening 1d provided at the center.

Further, the glass container body 1 has a flat shape such that the height H including the cylindrical container opening 1d is about 1/2 of the outer shape D. However, the shape and proportion of such a container are not particularly limited. However, the recess 1c is optimally located substantially in the center of the bottom wall 1a as in the present embodiment, and it is preferable that the recess 1c and the container opening 1d face each other substantially vertically. As the core material 2, any material having various impregnating properties such as felt can be used.

That is, since the remaining amount of the fragrance in the container body 1 is close to any of the surrounding portions in the limited concave portion 1c provided substantially in the center of the inner surface of the bottom wall 1a of the container body 1, it is easy. In addition to flowing in almost uniformly, this recess 1
c is located substantially in the center and is located substantially below the mouth 1d of the container body 1, and the core material 2 inserted from the mouth 1d is shown in FIG.
As shown by the phantom line in FIG.
Since one end faces inwardly without being bent and fits well into the recess 1c, almost all the remaining amount of the fragrance in the container body 1 can be sucked and diverged. Therefore, it is possible to prevent expensive fragrances from being used up and discarded.

Since the recess 1c is formed thinner than the wall thickness 1b of the bottom wall 1a of the glass container body 1, the bottom wall of the glass container body 1 is formed to form the recess 1c. Since the downwardly projecting portion is not formed on the lower surface of 1a, it is possible to avoid such a disadvantage that such a projecting portion is formed and the glass container body 1 is poorly placed and difficult to use.

Further, in this embodiment, the recess 1 is further provided.
As shown in FIG. 1, c is formed to have a diameter D2 having a size substantially corresponding to the thickness D1 of the core material 2 for absorbing and diverging the fragrance. As a result, since the concave portion 1c has a diameter D2 that substantially corresponds to the thickness D1 of the core material 2, it is easier to suck up and diffuse the remaining amount of the fragrance agent flowing into the concave portion 1c, so that the fragrance agent can be used more easily. .

In the present embodiment, in manufacturing the glass container body 1 as described above, as shown in FIG. 2, the gob 4 put in the rough mold 3, the baffle 5 and the mouth mold 6 are included. The protrusion 7a corresponding to the upward recess 1c to be formed on the bottom wall 1a of the glass container body 1 is pressed between the rough mold 3 and the plunger 7 having the tip surface 7b. As a result, the gob 4 is press-fitted into the mouth die 6 to form the parison 8 having the container mouth 1d of a predetermined shape, and at the same time as this formation, the outer surface of the bottom wall 1a of the parison 8 is attached to the baffle 5 on the rough die 3 side. Is formed flat by the flat surface 5a of the bottom wall 1a.
The inner surface of the is the tip surface 7 having the protruding portion 7a of the plunger 7.
b to be formed, and the peripheral portion 1b is formed by the protrusion 7a of the plunger 7 at the substantially central portion of the inner surface of the bottom wall 1a.
After forming the concave portion 1c having a smaller wall thickness, the parison 8 is blown as shown in FIGS. 3 and 4 in a curing state which precedes the other portion 1b due to the thin wall thickness of the concave portion 1c. Then, the part other than the container port 1d is finished along the inner surface of the finishing die 9 for finish molding.

In this way, the rough mold 3 and the plunger 7 are used to form the recess 1c having a wall thickness smaller than that of the bottom wall 1a of the container body 1 without any special work when the parison 8 is normally molded. Moreover, since the recess 1c has a smaller wall thickness and is cooled and hardened prior to the other portion 1b, the parison 8 is blown immediately without any time lag after the parison 8 is molded. Then, the finish mold 9 is used for finish molding, and while the concave portion 1c is in a cured state, its shape is maintained, and the other portions except the container port 1d and the concave portion 1c are finish-molded as usual. It is possible to manufacture the glass container body 1 of a container of an aromatic agent as shown in FIG. 1 without causing a decrease in productivity and an increase in cost.

In the present embodiment, the depth of the recess 1c is about 2.
Although the thickness of the other portions excluding the concave portion 1c and the container opening 1d is about 6 mm, the thickness is not limited to this. Further, regardless of the above description of the present embodiment, depending on the shape and size of the container body 1, the finishing die 9 may be used.
It goes without saying that various molding methods can be adopted in which the parison 8 is pre-blown before being blow-finished by using the above method to bring the parison 8 to a finish shape to some extent and then blow-finishing.

[0024]

According to the container of the fragrance and the like of the first aspect of the present invention, the remaining amount of the fragrance and the like in the glass container body flows into the recess of a limited range provided on the bottom wall of the glass container body. The upper and the recesses are located substantially in the center of the bottom wall and directly below the mouth of the glass container body.The core and the pipes passed from the mouth only extend right below the end without bending into the recess. The core material and tube are prevented from swinging from the proper suction position due to being caught in the recess, and almost all of the remaining amount of fragrance etc. in the glass container body can be sucked out. Therefore, it is possible to prevent expensive fragrances and the like from being used enough and not being discarded.

Further, the recess is formed by making the wall thickness thinner around the bottom wall of the glass container body, and the lower surface of the bottom wall of the glass container body projects downward to form the recess. Since such a portion is not formed, it is possible to avoid the inconvenience that such a protruding portion is formed and the glass container body is poorly placed and is difficult to use.

According to the invention of claim 2, in addition to the invention of claim 1, further, since the recess has a size substantially corresponding to the thickness of the core material, the remaining amount of the fragrance flowing into the recess is completely sucked out. It can be diverged to make it easier to use and cut.

According to the method for producing a container of fragrance or the like according to the third aspect of the invention, the concave portion having a wall thickness thinner than that around the bottom wall of the glass container body is formed by the rough mold and the plunger.
It is possible to form the parison at the same time without any special work during normal molding, and use the fact that this recess cools and cures earlier than other parts due to its thin wall thickness. The final mold by the finishing mold and maintain the shape of the concave part by the hardening state of the concave part, and finish molding other parts as usual, thereby reducing the productivity and increasing the cost. The container of the fragrance or the like of Item 1 can be manufactured.

According to the apparatus for manufacturing a parison for a container of a fragrance or the like according to the invention of claim 4, the inner surface having the recessed portion of the bottom wall of the parison is provided in the rough mold capable of forming the outer surface of the flat bottom wall of the parison of the glass container body. The parison in the method of the invention of claim 3 can be formed by a normal parison molding operation, in which a plunger having a protrusion on its tip surface for forming a groove is formed, and this is finished in the method of the invention of claim 3. It is sufficient if used for molding, and productivity is further improved.
