Abstract

PURPOSE:To keep the inside of a bottle in an aseptic condition and also eliminate the need for any sealer removal operation, by providing a thin sealer capable of being broken through easily by a content filling nozzle and making the adhesive strength between a lid and the sealer greater than that between the sealer and a bottle neck. CONSTITUTION:After formation, a bottle 1 made of a synthetic resin is kept in an aseptic condition and a thin sealer 2 is attached to the neck portion 4 thereof. The bottles 1 are packed in cases and shipped to a content filling factory, where the bottle is placed on a filling line, the sealer 2 is broken through by a filling nozzle, contents are filled in the bottle and then a lid 3 is attached on the sealer 2. Here, the adhesive strength between the sealer 2 and the neck portion 4 is such as to permit an easy separation and that between the lid 3 and the sealer 2 is made much greater than the former. When pouring out the contents, therefore, the lid 3 is removed together with the sealer 2 remaining attached thereto, with the neck portion 4 open. Consequently, there is no need for providing a separate process to remove the sealer 2.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a sealed bottle that prevents invasion of germs.

[Prior Art] Conventionally, the mouth of the bottle remains open during the transportation process from when the bottle is molded to when the contents are filled into the bottle, which prevents bacteria from entering the bottle. It was easy to maintain hygiene.

Therefore, in order to clean and sterilize the inside of this bottle, it is necessary to carry out cleaning immediately before filling the contents, which is a troublesome operation.

[Problem that the invention seeks to solve]

In order to solve these problems, a method can be considered in which the interior of the bottle after molding is made aseptic, a sealing piece is adhered to the mouth part during transportation, and the sealing piece is peeled off before filling the bottle with contents.

However, this method requires a step of peeling off the seal piece, which poses the problem of being very time-consuming.

The present invention was devised in view of these problems, and aims to provide a bottle that maintains a sterile state inside the bottle after molding and does not require a time-consuming process such as a step of peeling off a seal piece.

[Means for solving problems]

Therefore, the synthetic resin loading body 1 is kept in a sterile state.

A thin sealing piece 2 that can be easily broken by the content filling nozzle is adhered to the bottle body 10 part 4.

A lid body 3 was firmly adhered onto the seal piece 2.

Then, the adhesive force between the seal piece 2 and the mouth part 4 is
In addition, the adhesive force between the lid body 3 and the seal piece 2 is made to be much larger than the adhesive force between the seal piece 2 and the mouth part 4.

[Effect]

The sealed bottle 1 of the present invention is made by molding a synthetic resin loaded body 1, and then sterilizing the bottle 1 in a sterile atmosphere, and then adhering a thin sealing piece 2 to the opening 4. This keeps the inside of the bottle 1 in a sterile state.

The bottle 1 sealed with the seal piece 2 is packed in two boxes and transported to a filling factory, but since the seal is achieved even during such handling, no bacteria will enter.

In a content filling factory, a sealed bottle 1 placed on a filling line is filled with the content at the same time as the seal piece 2 is pierced by a filling nozzle.

After filling the contents, the lid 3 is adhered onto the seal piece 2.

The part of the seal piece 2 that is torn by the filling nozzle should be kept to the necessary minimum, which is slightly larger than the outer diameter of the filling nozzle, and that the air inside the tank should be kept to a minimum as the content occupies the tank during filling. will escape into the outside air, and the outside air containing a lot of germs will not enter the tank.Furthermore, after filling is completed, the filling nozzle will be removed from the tank, and the broken part of the seal piece 2 will be elastically restored. Close up most of the parts that have been torn open.

As a result, compared to the case where the seal piece 2 is completely peeled off and the mouth is left wide open, the risk of germs and the like entering is extremely small.

In addition, since the adhesive force between the seal piece 2 and the mouth part 4 is set to such an extent that it can be easily peeled off, and the adhesive force between the lid body 3 and the seal piece 2 is set to be much larger than that, when pouring out the contents, Lid body 3
When it is removed, the seal piece 2 is removed while remaining adhered to the lid body 3.

The mouth portion 4 is in an open state. Therefore, there is no need to provide a separate process for peeling off the seal piece 2.

〔Example〕

An example is shown in FIG. This is done by gluing 2 synthetic resin film-like seal pieces 2 to the mouth 4 of 2 synthetic resin-loaded bodies. A flat cover 3 made of synthetic resin that is thick and has a mechanical strength that cannot be easily penetrated.
are firmly adhered.

The adhesive force between the seal piece 2 and the bottle body 10 part 4 is such that the seal piece 2 is not peeled off unnecessarily during handling of the bottle l, and when opening the mouth part 4, the seal piece 2 is secured to the mouth part 4 together with the lid body 3. The material is such that it can be easily peeled off. Seal piece 2 and mouth part 4.
The lid body 3 and the seal piece 2 may be bonded together by welding or adhesive.

This is achieved through existing means. Further, the materials of the sealing piece 2, the lid 3, etc. are appropriately selected depending on the adhesive means.

In the second embodiment, the lid body 3 is in the form of a flat plate, but it may also be of a so-called fit-in type that is fitted and assembled into the bottle body 10 section 4.

〔Effect of the invention〕

In this way, the present invention maintains the inside of the tank in a sterile state at all times to prevent bacteria from entering.

Extremely hygienic. In addition, since there is no need for the step of peeling off the seal piece that maintains a sterile state, it exhibits many excellent effects such as improving work efficiency.
