Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an ultra-thin blow bottle, and more particularly to an ultra-thin refill bottle equipped with a base cup that engages a base cup with the mouth of the bottle and holds the bottle upside down.
[0002]
[Prior art]
In recent years, thinning of blow bottles has been required due to the reduction of plastic materials and the reduction of plastic waste. With blow bottles of PP, PET, etc., the barrel thickness can be easily crushed to around 0.1 mm. The bottle has been commercially available.
[0003]
[Problems to be solved by the invention]
However, in order to further save the material, if the amount of resin per unit volume is lowered and the thickness of the barrel is 0.1 mm or less, the barrel is deformed when filled with the content liquid. There was a problem.
As a result, the bottle cannot be held upright and it is difficult to carry the package.
Also, when transferring the content liquid as a refill bottle, if you try to transfer it by grasping the shoulder or upper part of the torso, the mouth will move due to deformation and it will be difficult to pour it into another bottle There was a point.
[0004]
SUMMARY OF THE INVENTION An object of the present invention is to provide an ultra-thin blow bottle in which a base cup is detachably attached to the mouth of a bottle with the object of solving the above problems.
[0005]
[Means for Solving the Problems]
In order to solve the above problems, the present invention provides an ultra-thin refill bottle with a base cup attached to the mouth of the bottle as an ultra-thin refill bottle with a base cup, The refill bottle has a predetermined thickness and a mouth reinforced by a neck ring, and an ultra-thin shoulder and torso, and the torso and shoulder cannot maintain a fixed shape by themselves. Constructed from a flexible ultra-thin film, the base cup has an outer cylinder, an upper wall, a conical cylinder that is connected to the inner circumference of the upper wall, and a vertically extending from the inner end of the conical cylinder. It consists of an inner cylinder provided with a locking ring that bulges, and the outer cylinder has an inner diameter equal to the outer diameter of the body of the bottle, and the height is equal to or higher than the height of the shoulder of the bottle, The inner cylinder has an inner diameter substantially equal to the diameter of the neck ring at the mouth of the bottle and the outer diameter of the inner cylinder. Employs a configuration which is characterized in that the mouth portion has a fitted possible diameter, in one embodiment, when attached to the mouth portion of the refill bottle filled with liquid contents of the base cup, shoulder The reversing bottle filled with the content liquid is supported by using the outer surface of the upper wall as a stable support surface by reversing the upper end edge of the body portion as a support shaft and pressurizing the inside of the container. Is adopted.

DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings.
In FIG. 1, A is a refill bottle covered with a cap B, and C is a base cup.
The bottle A includes a mouth part 1 and a shoulder part 2, a body part 3 and a bottom part 4, and the mouth part 1 is provided with a screw 5 and a neck ring 6.
A plurality of known radially extending ribs or other reinforcing ribs are formed on the bottom wall of the bottom portion 4 to be reinforced.
The shoulder 2 and the body 3 are circular in cross section.
[0007]
The cap B is a known screw-type cap, and a screw that is screwed into the screw 5 of the mouth portion 1 is screwed on the inner periphery.
[0008]
The bottle A is made of a hard synthetic resin such as PET or PP, and is formed by biaxial stretch blow. In the case of PET, the amount of preform resin per unit volume of the bottle is about Although it was around 0.04 g / ml, in the examples of the present invention, the amount of resin was molded at 0.025 g / ml or less, and the body portion 3 was in the form of a film having a thickness of 0.05 mm or less.
[0009]
In the case of PP, in the conventional one, the amount of resin was around 0.025 g / ml, but in the example, it was molded at 0.024 g / ml or less, and the thickness of the body part 3 was 0.1 mm or less, The range is 0.05 mm or more.
[0010]
The mouth portion 1 is thick and is reinforced by screws 5 and a neck ring 6, and the bottom portion 4 is also reinforced by reinforcing ribs to maintain a certain strength.
However, since the body part 3 is in the form of a film, it is maintained in a certain shape by the liquid pressure of the content liquid when filled with the content liquid, but in order to maintain the shape, some holding member is required. In the present invention, a hook or base cup is used.
[0011]
The base cup C includes an outer cylinder 10, an upper wall 11, a circular cylinder 12 connected to the inner end of the upper wall 11, and an inner cylinder 13 that hangs down from the inner end edge of the circular cylinder 12.
The inner diameter of the outer cylinder 10 is made equal to the diameter of the body part 3 of the bottle A, and the height thereof is larger than the height of the shoulder part.
The inner cylinder 13 has a larger diameter than the neck ring 6 of the bottle A, and a locking ring 14 is formed on the inner periphery of the lower end so as to engage with the lower side of the neck ring 6.
[0012]
Next, the usage mode and effect of the base cup of the refill bottle of the present invention will be described.
When the base cup C is pushed into the bottle A covered with the content liquid and covered with the cap B from above, the bottle mouth 1 is pushed down by the lower end of the inner cylinder 13 of the base cup C, as shown in FIG. The bottle mouth part 1 descends while denting the shoulder part 2.
When the locking ring 14 of the base cup C is engaged with the lower side of the neck ring 6, the boundary between the shoulder 2 and the trunk 3 comes above the upper end of the mouth 1 and contacts the upper wall 11. The shoulder 2 is deformed so as to be reversed with the boundary with the body 3 as a support shaft, and a head space h is formed in the upper part of the body 3.
[0013]
As shown in FIG. 3, when the bottle A is inverted, the head space h is replaced with the content liquid, and the upper part of the body 3 of the bottle A is placed on the upper wall 11 and the outer cylinder 10 of the base cup C depending on the weight of the content liquid. The content liquid is held by the base cup C through the wall surface of the bottle A, and the body portion 3 is prevented from being deformed.
[0014]
When refilling the contents liquid, when the bottle A is erected and the base cup C is lifted upward, the mouth portion 1 comes out upward by the locking ring 14 of the inner cylinder 13 and further pulls out the base cup C. Then, the locking ring 14 comes off from the neck ring 6, and the bottle A is restored to the original state.
[0015]
Next, as shown in FIG. 4, the base cup C is inserted into the mouth of the main body bottle D, the cap B of the refill bottle A is removed, and the content liquid is transferred to the main body bottle D.
When transferring, the body 3 of the refill bottle A is gripped, and even if the mouth 1 is not stable because it is thin, the upper part of the cylinder 12 of the base cup C has a large diameter. Play a role and never spill out.
[0016]
【The invention's effect】
Since this invention is comprised as mentioned above, there exists the following effect.
By attaching the base cup to the mouth of the bottle, when the bottle is inverted, the content liquid is retained by the base cup, and the shoulder and body of the bottle can be maintained in a certain shape, so the content liquid is filled. Bottle packaging and transportation became easier.
Since the base cup can be attached to the mouth of the main body bottle and used as a funnel, the contents can be easily transferred.
