Description

TECHNICAL FIELD [0001] The present invention relates to a double browbeat structure involving a plurality of containers,

In particular, the present invention relates to a method of manufacturing a double-browed container, and more particularly, to a method of manufacturing a double-browed container in which an outer container and a content container are made of the same material and a thin film made of a separate release material is placed between the outer container and the content container, The outer container and the thin film of the release material are concurrently blown to form a container shape. In the blowing process, the outer container and the inner container of the same material are separated from each other by the thin film of the release material And are made to adhere to each other through a cut groove formed in the film.

By the use of the above-mentioned manufacturing process, the contents are contracted due to the volume reduction, and the position where the contents are bonded is fixed to the state in which they are not moved in the direction of the center to fix the side of the contents as a whole, The present invention relates to a container for manufacturing a double-browed container having a thin film form capable of using all the contents contained in the container, and having a structure capable of using the entire amount in the container.

Containers that contain cosmetics or toothpastes that are a care product group, containers that contain the contents of gels, cream-type detergents, medicines, etc. may be accommodated in a container called a tubular container or used in a container of a round shape And is accommodated and used.

In the case of a conventional cap, a user may open the cap to press the outer surface of the tubular container to squeeze out, or in the case of a hardenable container, The pump type is applied to the cap itself and when the upper part of the cap is pumped, the contents are discharged to the cap side through the deep tube which has entered the inside of the container, It takes the form of a generalized structure.

However, it is difficult to use all the contents contained in the container due to the structural characteristics of the container and the diptube in a structure in which the diptube is connected to the container from the lower end portion of the container and is used by discharging the contents by pumping. When the contents are not discharged through the deep tube after use, the remaining amount is often used after incising the container by using a tool such as a scissors or a knife. However, such use is troublesome and unsanitary.

For this reason, after using the contents of the container, some of the residual amount remaining is discarded together with the container without being used. Therefore, it is recognized that it is not preferable from the economic and environmental point of view, and problems are raised. Has come.

As a method for solving such a problem, there is disclosed a non-residual quantity tube container which is disclosed in Korean Patent Registration No. 10-1467736. In the above-mentioned prior patent, a piston which is closely attached to the inner wall surface of the tube container is provided, Thereby completely discharging the remaining amount of the contents in the container.

However, in the case of the prior art, there is a need for a work process in which the piston and the lower cover member are provided to press the lower cover member and the piston to squeeze the contents.

In addition, a vacuum pump is formed on the cap (cap) which is connected to the upper end of the container, and the contents inside the container are extracted by the pumping operation, and the pipe connected to the vacuum pump reaches the bottom surface of the container, There is a problem in that a substantial amount of the contents remain in the inside and outside of the tube and that there are many remaining amounts in the side and the bottom surface of the inside of the vessel to use the remaining amount completely.

In addition, in the case of the container using the vacuum pump as described above, there is also an economical burden in that the production unit price remarkably increases.

Therefore, in order to overcome such a problem, the inventors of the present invention propose a constitution in which the container is divided into an outer container and a content container, and the content container is introduced into the outer container. A method of manufacturing a broaching storage container is disclosed.

The above-mentioned patent discloses a method for producing a preform, comprising a first-stage blowing step of forming an outer container by primary blowing using a hard synthetic resin material, a step of forming a second preform by using a soft synthetic resin material, And a secondary blowing step of inserting into the preformed external apparatus by the primary blowing step and secondary forming the inner vessel to form a content vessel.

When the content container using the secondary preform as shown in the above-described manufacturing method is inserted and formed into a hard outer container, the content container is kept in close contact with the inner side surface of the outer container, The contents are discharged to the outside by using a pump-type stopper.

There is a container of the present invention to which the above-mentioned content container and the external container are applied, a container having a structure which can be used in full quantity, which is the Korean Patent Registration No. 10-1611211 registered by the present inventor for registration in the Korean Intellectual Property Office, Valve can be used.

In the process of registering the prior patent of the present invention, it is an invention capable of solving the above-mentioned problem, but the thin film type content container accommodated in the outer container discharges the contents to the outside, That is, there is a problem that the contents of the lower end of the stopper and the area of the container discharge port side always remain.

According to the structure of the prior art, when the dip tube is configured to be relatively short, there is a problem that the contents remain at the side of the stopper and the area of the container discharge port. On the other hand, When the phenomenon that the lower end portion of the dip tube is blocked by the thin film type content agent is generated in the process, the flow path through which the contents are discharged to the outside is completely blocked, There is a problem that the contents can not be discharged.

Accordingly, in the case of a container constituting a thin film type content container, it is necessary to exclude the phenomenon of blocking the path for the contents to flow out through the dip tube toward the cap side when the content container made of the thin film is compressed.

However, the above-described method and configuration can be solved mainly by a configuration change of the dip tube, and an attempt to solve the problem through an approach by other methods is needed.

As one of the attempts for this, a method of improving the structure of the dip tube may be proposed, but unlike the improvement of the dip tube, it is necessary to be able to achieve the effect by changing the structure of the medium.

Therefore, one of the attempts at the above-mentioned problematic attitude is to use the entire contents of the contents in the double broke container made of the content container and the outer container, which was filed by the present applicant in the patent application No. 10-2016-78996 (June 26, 2016) A possible container structure ".

The above-

"A primary blowing step of forming an outer container by primary blowing using a hard synthetic resin material, a step of forming a secondary preform by using a soft synthetic resin material, heating the secondary preform, A double-broke storage container comprising a secondary blowing step of inserting into a preformed external apparatus by a blowing step and secondary molding to form a content agent,

The extrudate is extruded so as to form a protruding support portion at the 4-point point of the secondary preform, and then the secondary preform is inserted into the primary outer-shell outer container and blown to the outer peripheral surface 4- A container structure capable of using all of the contents in a container in a double-broke container made of a content container and an outer container, characterized in that a protruding support portion relatively thicker than the thickness of the broached area of the content container is formed and the container is formed. As shown in FIG.

That is, in the above patent, the protruding support portion of the 4-point point of the secondary preform constituting the content container is relatively thicker than the other portions, so that when the content inside the content container is discharged to the outside through the dip tube, The content container is supported by the projecting support portion, and the contents can be discharged to the outside as the volume decreases.

By this phenomenon, the content of the thin film type shrinks as it shrinks and the problem of blocking the dip tube can be solved.

However, in the case of the above-mentioned patent, since it is necessary to form a protruding support portion at a setting position after forming the preform shape of the content container, it is troublesome to change the structure of the extruder and to change the structure design of the extruder.

(S10) for preparing a first preform constituting an outer container made of the same material and a second preform for forming an inner container;

A third preform preparation step for forming a release film made of a material different from the material of the first and second preforms and disposed between the outer container and the preform for forming the inner container, S20);

The preforms obtained by combining the first, second, and third preforms obtained in the preform preparation step are inserted into a mold for blow molding, the first, second, and third preforms are simultaneously blown, 2, a blowing step (S30) in which the first and second preforms are joined to the incision groove of the third preform at the time of expansion of the preform, and the preform is molded into a container shape.

The first and second preform preparation steps (S10) refer to a step of obtaining a preform in the container from which the outer container and the content container are formed.

In the present invention, the first and second preforms are made of the same material. For example, it is important that the first and second preforms may be made of PETG, PP, or PE, and made of a different material from the third preform to be described later.

That is, the third preform obtained by the third preform preparation step (S20) has a thin film form, which is generally referred to as a release film 30 in the present invention. The third preform, which constitutes the release film 30, And denoted by reference numeral 30-1.

In the case of the content container 20, the container 20 has a thin film shape that is relatively thinner than the thickness of the outer container 10. In a state where the contents are contained in the container 20, ), And the volume decrease phenomenon should occur.

Meanwhile, as described above, the third preform 30-1 obtained by the third preform preparation step S20 includes the outer container 10 formed by blowing the first preform 10-1, The release film 30 is formed so as to have a thin film shape in which the preform 20-1 is placed between the content containers 20 formed by broaching.

In addition, the third preform 30-1 is preferably made of a different material from the first and second preforms 10-1 and 20-1 made of the same material.

For example, when the first and second preforms 10-1 and 20-1 are made of PETG resin, the third preform 30-1 is made of a PP material.

When the first and second preforms 10-1 and 20-1 are made of PP resin, the third preform 30-1 may be made of PETG resin or EVOH resin.

Alternatively, when the first and second preforms 10-1 and 20-1 are made of a PE resin material, the third preform 30-1 may be made of EVOH resin material.

That is, as in the above embodiments, the first preform 10-1 forming the outer container 10 and the second preform 20-1 forming the inner container 20 are made of the same material, The third preform 30-1 constituting the release film 30 disposed between the outer container 10 and the content container 20 is made of different materials.

At this time, as shown in the drawing, the third preform 30-1 is formed with the incision grooves 31 in the longitudinal direction to form the incision grooves 31 with the first and second preforms 10-1 and 20-1, And the first and second preforms 10-1 and 20-1, which are made of the same material, are brought into contact with each other and joined together through the cutout groove 31.

After the first, second and third preforms 10-1, 20-1 and 30-1 are obtained, the composite preforms (first, second and third preforms) obtained by the bonding are introduced into a mold for blow molding And the first, second, and third preforms 10-1, 20-1, and 30-1 are simultaneously blown, and the first and second preforms 10-1, 20-1, The first and second preforms 10-1 and 20-1 are bonded to the cutout groove 31 of the third preform 30-1 at the time of inflation so as to be subjected to a blowing step S30 .

3, the outer container 10 and the inner container 20 are formed of the outer container 10 and the inner container 10, And the release film 30 in the form of a thin film is placed between the substrates 20.

As described above, when the cut-out grooves 31 are formed on the sides of the release film 30 and the preforms 10-1, 20-1, and 30-1 are expanded by the blowing step S40 The outer container 10 and the container 20 come into contact with each other through the cutout grooves 31 and are in a state of being fixed by the same material characteristics.

In this state, when the contents are filled in the contents container 20 and the stopper 40 having the pumping means is coupled to the discharge port side of the external container 10, The contents are continuously discharged to the discharge port 41 provided at the side end of the stopper 40 through the diptube 50 accommodated in the contents container 20.

In this process, the volume of the contents container 20 is reduced by the discharging action of the contents. The volume of the contents container 20 is reduced through the cutout grooves 31, The area where the outer container 10 and the inner container 20 are separated from each other by the release film 30 as a whole is separated from the inner container 20 by the release film 30, The volume of the container 20 is reduced and the volume is reduced toward the center of the container 20, and both sides of the container 20 are longitudinally joined and fixed to each other at the junction through the cutout groove 31, The region 20 of the region is gathered at the center and the volume reduction phenomenon occurs.

When the volume of the contents container 20 is reduced due to the operation of the container 20, the contents container 20 may be pushed upwards.

4, in order to induce a volume reduction phenomenon in a state in which the content container 20 is entirely opened, in order to form a minute gap at the bottom surface of the outer container 10, It is preferable to form the clearance portion 11 at the bottom of the recess 10-1.

When the first, second, and third preforms 10-1, 20-1, and 30-1 are combined and blown by the gap portion 11 and are simultaneously inflated, the bottom portion of the second preform 20-1 The bottom side of the third preform 30-1 is held in the gap portion 11 and remains fixed.
