Description

[0001] PLASTIC DUAL CONTAINER [0002]

The present invention relates to a plastic double container, and more particularly to a plastic double container having an inner layer for receiving an object and an outer layer forming the outer appearance of the container.

BACKGROUND ART [0002] Plastic containers are widely used for accommodating various objects such as beverages, food ingredients, medicines, cosmetics, and the like.

Most plastic containers are made up of only one layer but for the purpose of maximizing the contact of oxygen with the inner receptacle or increasing the convenience of the operation of discharging the inner receptacle, a double container comprising an inner layer and an outer layer It is also used.

One example of a plastic double container according to the prior art is shown in Figs.

This plastic double container 10 includes a container body 20 and an upper cap 30 coupled to the top of the container body 20. The container body 20 includes an inner layer 21 for receiving contents and an outer layer 22 surrounding the container body 20. [ .

On the bottom surface 23 of the outer layer 22, an air inlet / outlet hole 23a having a linear clearance is formed. The air inlet and outlet holes 23a are for introducing air into the outer layer 22 and may be simultaneously formed on the bottom surface 23 of the outer layer 22 in the process of molding the container body 20 by the blowing method.

As shown in FIG. 2 (a), as the amount of the inner contents decreases, the shape of the inner layer 21 is deformed and the volume gradually decreases. On the other hand, the air introduced through the air inlet / (22) can be restored to its initial form.

The user uses the container 10 in such a manner that the outer layer 22 is compressed and the inner receptacle is discharged to the outside. As shown in FIG. 2 (a), when the amount of the inner receptacle is reduced, A phenomenon that the user's compressive force is not transmitted to the inner layer 21 easily occurs due to the air discharge through the inner layer 23a.

In this case, in order to discharge the inner receptacle to the outside, the user presses the outer layer 22 so that the pressing force applied to the outer layer 22 is directly transmitted to the inner layer 21. In this process, the user feels a great inconvenience.

Japanese Patent No. 4228362 (registered on Dec. 12, 2008)

The object of the present invention is to provide a plastic double container in which the discharge of the internal contents can be easily carried out even if the air discharge hole is provided on the external bottom surface.

In order to achieve the above object, the present invention provides a container body comprising: an inner layer for accommodating an object; and an outer layer having a first air inlet / outlet hole formed on a bottom surface thereof; And a lower cap mounted on a lower end portion of the container body, the lower cap having a second air inlet hole having a flow passage area smaller than the flow passage area of the first air inlet / outlet hole.

The first air inlet / outlet hole may have a linear gap shape.

Wherein the lower cap includes: a bottom portion disposed to face a bottom surface of the outer layer; And a side portion disposed to face a side surface of the outer layer.

The second air inlet / outlet hole may be formed as a through hole formed in a boundary region where the bottom portion and the side portion meet.

The second air inlet / outlet hole may be formed in a central region of the bottom portion.

And the second air inlet / outlet hole may be provided with a concave groove extending at least on the inner side surface of the side portion.

The inner surface of the side surface of the lower cap may have an engaging rib formed in a circumferential direction and an outer surface of the outer surface of the container body may have an engaging groove into which the engaging rib is inserted.

According to the present invention, by mounting the lower cap having the other air discharge hole having the flow path cross-sectional area smaller than that of the air discharge hole on the outer layer floor to the lower end of the plastic double container, the amount of air discharged to the exterior So that the compressive force applied to the outer layer can be well transferred to the inner layer through the inner air layer, so that the inner receptacle can be smoothly discharged to the outside.

Therefore, when the conventional plastic double container is used, the remaining amount of the internal contents is reduced, and the inconvenience due to the inadequate discharge of the internal contents can be solved.

Hereinafter, a plastic double container according to one embodiment of the present invention will be described in more detail with reference to the accompanying drawings.

FIG. 3 is an exploded view of a plastic double container according to an embodiment of the present invention, FIG. 4 is a bottom view of the container main body of the plastic double container of FIG. 3, Fig.

The plastic double container 100 according to one embodiment of the present invention shown in FIGS. 3 to 5 is suitable for use in storing and containing food materials such as soy sauce, oil, mayonnaise, ketchup, etc. However, none.

3 to 5, the plastic double container 100 includes a container body 110, an upper cap 120, and a lower cap 130.

The container body 110 is formed of a double container. That is, the container body 110 is composed of an inner layer 111 for accommodating objects such as food ingredients, drinks, cosmetics and the like and an outer layer 112 surrounding the inner layer 111.

The inner layer 111 is preferably made of a material exhibiting excellent oxygen barrier properties. For example, the inner layer 111 may be made of EVOH (ethylene vinyl alcohol). Thus, when the inner layer 111 is made of a material exhibiting excellent oxygen barrier properties, the food material contained therein can be safely stored for a long period of time without being decomposed.

The outer layer 112 is located outside the inner layer 111 to form an outer appearance of the container body 110. The outer side surface 112b of the outer layer 112 is formed with a coupling groove 114 in a concave shape along the periphery thereof. The coupling groove 114 is for coupling of the lower cap 130 to be described later. For example, the outer layer 112 may be made of a common plastic material such as polyethylene or polypropylene.

A first air inlet / outlet hole 117 is formed in the bottom surface 112a of the outer layer 112. [ Air can flow in and out of the outer layer 112 through the first air inlet / outlet hole 117. As shown in FIG. 4, for example, the first air inlet / outlet hole 117 may have a linear clearance shape.

The container body 110 composed of the inner layer 111 and the outer layer 112 can be manufactured by a blow molding method which is one of the plastic manufacturing methods. The inner layer 111 and the outer layer 112 are formed by the blow molding method The first air inlet hole 117 may be formed at the bottom surface 112a of the outer layer 112 at the same time.

By applying such a blow molding method, the first air inlet / outlet hole 117 typically has a linear shape. However, in the case of forming the first air inlet / outlet hole 117 simultaneously during blow molding, as shown in FIG. 4, the first air inlet / outlet hole 117 has a relatively long length and the first air inlet / 117) to have a significantly reduced length is virtually impossible.

Alternatively, it is possible to consider a method of finishing the inner layer 111 and the outer layer 112 and then forming a small first air inlet hole 117 at the bottom of the outer layer 112 through a post-process (for example, punching) However, this method is difficult to apply in practice because a hole is likely to be formed in the bottom of the inner layer 111.

The upper cap 120 is mounted on the upper end of the container body 110 and serves to open and close the upper opening of the container body 110. 5, the upper cap 120 includes a body part 121 coupled to the container body 110, and a closure 122 closing the outlet 121a of the body part 121. As shown in FIG.

Although not shown, the body portion 121 of the upper cap 120 has a self-closing function. 5, when the container body 110 is compressed by an external force, the discharge port 121a of the body part 121 is opened. However, when the closure 122 is in the open state, The discharge port 121a of the body part 121 is automatically closed. For example, this self-closing can be realized through a configuration such as a membrane valve that receives the compressive force and is deformed upward and returned to its original position upon release of the compression. Various self-closing implementations are well known in the art. A more detailed explanation will be omitted.

The lower cap 130 is mounted on the lower end of the container body 110. The lower cap 130 includes a bottom portion 130A disposed to face a bottom surface 112a of the outer layer 112 and a side portion 130B disposed to face a lower side surface 112b of the outer layer 112. [

A coupling rib 131 formed in a circumferential direction is formed on the inner surface of the side portion 130B of the lower cap 130. [ By inserting the engaging rib 131 into the engaging groove 114, the lower cap 130 can be coupled to the container body 110. In this embodiment, the lower cap 130 is provided with the coupling rib 131 and the container body 110 is provided with the coupling groove 114. On the contrary, the lower cap 130 has the coupling groove 114 formed therein, The main body 110 may be provided with a coupling rib 131.

The lower cap 130 is provided with a second air inlet / outlet hole 132 in fluid communication with the first air inlet / outlet hole 117 of the outer layer 112 described above. In this embodiment, the second air inlet / outlet hole 132 is provided as a through hole formed in the lower cap 130. Also, in this embodiment, the second air inlet / outlet hole 132 is formed in the rounded boundary region between the bottom portion 130A and the side portion 130B in the lower cap 130.

Alternatively, the second air inlet / outlet hole 132 may be provided as a through hole located in the central region of the bottom portion 130A. However, since the plastic double container 10 is placed on a flat surface such as a table, 3, the second air inlet / outlet hole 132 in the form of a through hole is formed in a boundary region between the bottom portion 130A and the side portion 130B, More preferably,

The second air inlet / outlet hole 132 has a size much smaller than the size of the first air inlet / outlet hole 117 described above. The second air inlet / outlet hole 132 has a flow path cross-sectional area much smaller than that of the first air inlet / outlet hole 117. Preferably, the flow path cross-sectional area of the second air inlet / outlet hole 132 is about 5 to 10% of the flow passage cross-sectional area of the first air inlet / outlet hole 117.

As shown in FIG. 5, when the inner receptacle is to be discharged to the outside, the user presses and compresses the outer layer 112. Then, the compressive force applied by the user is transmitted to the inner layer 111 through the air layer inside the outer layer 112, so that the inner receptacle is discharged to the outside through the discharge port 121a.

At this time, a part of the air inside the outer layer 112 is discharged to the outside through the second air inlet / outlet hole 132 in fluid communication with the first air inlet / outlet hole 117, Since the cross-sectional area of the flow path is much smaller than the cross-sectional area of the flow path of the first air inlet / outlet hole 117, the amount of air discharged to the outside through the second air inlet / outlet hole 132 becomes insignificant, The discharge operation of the water can proceed smoothly.

When the user releases the compressive force applied to the outer layer 112, the outer air is introduced into the outer layer 112 through the second air inlet / outlet hole 132 and the first air inlet / outlet hole 117, Is returned to its initial form. Since the size of the second air inlet / outlet hole 132 is small, the return time of the outer layer 112 may be long. However, such a return process is generally performed during non-use, so that the user does not feel any particular inconvenience.

FIG. 6 is a view showing another example of the second air inlet / outlet hole provided in the plastic double container of FIG. 3;

As shown in the figure, the second air inlet / outlet hole 132 may alternatively be provided in the form of a recess formed in the inner surface of the lower cap 130. As shown in FIG. 6, the second air inlet / outlet hole 132 in the form of a concave groove may be formed to be long in the vertical direction on the inner surface of the side portion 130B of the lower cap 130. Alternatively, the second air inlet / outlet hole 132 in the form of a concave groove may extend further from the side portion 130B of the lower cap 130 to a portion of the bottom portion 130A.

The second air inlet / outlet hole 132 in the form of a concave groove likewise has a flow channel cross-sectional area significantly smaller than that of the first air inlet / outlet hole 117. For example, it is preferable that the size of the flow path cross-sectional area of the second air inlet / outlet hole 132 in the concave groove shape is also about 5 to 10% of the flow passage sectional area of the first air inlet / outlet hole 117.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims. It can be understood that
