Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid container, and more particularly to a thin plastic bottle type container used for refilling and the like, and a sealing member for the container.

[0002]

2. Description of the Related Art In recent years, refilling containers have been used in consideration of resource saving and reduction of refuse, and bag-like containers, pouch containers, thin plastic bottle-type containers, and the like have been used. Above all, a thin plastic bottle-type container can be easily manufactured at low cost with a synthetic resin material or the like, and is more self-sustainable than a pouch container, which is expensive because of forming a laminate including an aluminum layer. Due to its high cost, it is demanded as a refillable container for storing contents such as liquid detergents and liquid cosmetics.

[0003] By the way, if a container having a high shape retention property is used as a refill container, even if it is empty, since the container has a space inside, the manufacturer of the container may use the container. When the contents are distributed to a user (detergent maker or the like) who fills the contents, the distribution costs are high as in the case of the containers after the filling, and the materials are bulky at the time of disposal.

[0004] On the other hand, the above-mentioned thin plastic bottle-type container, even if it is made ultra-thin so as not to be self-supporting when the content is not filled, the content is stored in the container. Once filled, they can be fully self-sustaining. Moreover, since the shape retention can be lowered, the volume at the time of distribution or disposal can be reduced by folding.

When such a thin plastic bottle type container is used especially for refilling, its opening is
It suffices that the contents be sealed until the contents are filled and the contents are refilled into a main container with a dispenser that can be used multiple times, for example. However, in the conventional thin plastic bottle container for refill, like the bottle container that can be used multiple times,
A cylindrical projection or the like was provided near the opening, and a cap or the like was fitted to the cylindrical projection to seal the container.

In addition, in a normal bottle type container, in order to directly provide information display such as front surface display and rear surface display on the container, the surface whose surface roughness is increased by corona treatment is printed by, for example, gravure printing or the like. On the other hand, in the above-mentioned thin plastic bottle-type container, it is difficult to perform such a process. For example, a shrink label or the like in which a printed plastic film is shrunk and brought into close contact with the container is used. In order to attach such a shrink label, there is a limit in reducing the thickness of the container. That is, in the case of an ultra-thin container that does not have self-sustainability in a state where the contents are not filled, it is difficult to print on the surface and attach a shrink label, and a simple alternative information display method is used. Has not yet been proposed.

In addition, in the above-mentioned ultra-thin container,
When refilling the contents from the refill container to the main container,
If the container is pressed by hand, the contents may be pushed out and fly out.

Further, in a usual bottle type container, since the containers are independent of each other, when the filling is performed, for example, on a line, it is necessary to align the individual containers.

[0009]

SUMMARY OF THE INVENTION An object of the present invention is to provide a thin plastic bottle-type container and a sealing member for the container, which advantageously solve the above-mentioned problems in the prior art.

[0010]

SUMMARY OF THE INVENTION A sealing member for a thin plastic bottle type container according to the present invention is a sealing member for sealing an opening of a thin plastic bottle type container having a hook at a bottle neck portion. Wherein the sealing member is formed of a bendable sheet material having a hook portion to be hooked on a hook portion of the bottle-shaped container, and a sealing portion for sealing an opening in the bottle-shaped container. is there.

In the sealing member for a thin plastic bottle-type container according to the present invention, the sealing member itself is made of a bendable sheet material, and its latching portion is formed of a bottle neck portion of the thin plastic bottle-type container. The sealing portion is fixed to the opening of the bottle-type container where the above-mentioned hooking portion is hung, and is sealed by the curvature of the sealing member.

Therefore, according to the sealing member for a thin-walled plastic bottle-type container, the hooking portion is sealed with the hooking portion in a state of being hooked on the annular flange of the bottle-neck portion of the thin-walled plastic bottle-shaped container. The container can be easily and inexpensively sealed by curving a portion between the container and the opening and sealing the opening of the bottle-shaped container with the sealing portion.

In addition, since the sealing member of the present invention is made of a sheet material, it is easy to perform printing or the like on portions other than the hook portions. Therefore, since such a sealing member used for the thin plastic bottle-type container plays a role of both sealing of the container and information display, it becomes possible to make the thin plastic bottle-type container ultra-thin, and as a result, The thin plastic bottle type container can be distributed at low cost and with resource saving.

In the sealing member for a thin plastic bottle-type container according to the present invention, the sealing portion is formed by cutting out from the material of the sealing member at a position separated from the hooking portion, and the hooking portion is formed. The part close to the part may be connected to the remaining part of the sealing member, and the remaining part may be curved so as to be able to be hooked on the engaging part. In this case, the remaining part is curved to form an annular flange or the like. By hanging on the hook,

By doing so, a plurality of empty, ultra-thin, thin-walled plastic bottle containers can be easily aligned in a crushed state. Therefore, a plurality of empty, ultra-thin, thin-walled plastic bottle containers can be distributed more in a small packing volume. Moreover, since the thin plastic bottle-type containers can be moved while maintaining the aligned state, the containers can be easily distributed to the user who fills the containers with the contents.

In addition, on the user side, since the thin plastic bottle-type containers are delivered in an aligned state, when the contents are filled in a line, a plurality of the aligned containers are maintained. It is possible to send the empty ultra-thin thin plastic bottle type container to the filling line and fill the container while dividing the sealing member, so it is necessary when delivered separately. It is not necessary to align the containers.

On the other hand, in the sealing member for a thin plastic bottle-shaped container according to the present invention, a plurality of the sealing members for a thin plastic bottle-shaped container according to any of the above are arranged in the longitudinal direction of the sealing member. They may be connected to each other to form a continuous sheet for a sealing member.

[0022] In this manner, the plurality of empty members are hooked on the annular flanges of the bottle necks of the individual thin plastic bottle-type containers by hooking the respective hooks of the plurality of sealing members connected to each other. Adjacent containers of the ultra-thin thin-walled plastic bottle-type container can be aligned while maintaining a relatively large interval. Therefore, the empty container can be circulated without being crushed, and the container can be filled with the contents while the plurality of sealing members remain connected. Moreover, when the container filled with the contents is distributed,
Maintaining the connection of the sealing members facilitates alignment of the containers during packaging.
