Detailed Description

Example one

A complete and saleable container may be formed by manufacturing, filling and sealing, and in this embodiment, the different process steps are shown as separate units for forming the container, wherein the packaging unit is the smallest unit of the container that forms the container during the manufacturing process of the package, and the packaging unit can form the container by opening the folding line of the packaging unit, and the embodiment is only directed to the packaging unit.

The present embodiment provides a first technical solution. The packaging unit comprises a unit body 1 and a circulating assembly, wherein the unit body 1 is in a conventional plate shape, the plate-shaped unit body is made of sheets or rolls common in the field and is cut into flat plates; the unit body can be of a single-layer structure, but is more often formed by compounding a multi-layer structure.

If necessary, taking the unit body 1 in a flat state as an example, if the top surface thereof is the outside of the container, the bottom surface may be the inside of the container; different regions are divided on the unit body 1 as respective faces of the container according to the intended shape of the container. The unit body 1 is provided with a through hole 2 in advance, and the through hole 2 can be arranged in the area divided into the top surface. The circulation assembly is arranged at the through hole 2 on the unit body 1, the circulation assembly at least comprises a bottle mouth 10 and a cover 4, if the bottle mouth 10 is filled, the cover 4 can be added after the filling without installing the cover 4 in advance. The bottle mouth 10 is arranged at the through hole 2 of the unit body 1 to ensure smooth communication between the bottle mouth and the through hole 2, preferably, the bottle mouth 10 is fixedly connected with the unit body 1 through a connecting piece 5, the connecting piece 5 can adopt any known structure and shape, and only the requirement of fixedly connecting the bottle mouth and the unit body is met; the fixing method of the bottle mouth 10 and the unit body 1 can adopt any existing technique, such as heat sealing, and the heat sealing process is an existing processing technique, and specifically can include but not limited to ordinary heat pressing sealing, fusing sealing, pulse sealing, ultrasonic sealing, high-frequency heat sealing, induction heat sealing and the like. Before filling, the circulation assembly is installed on the container, later installation is not needed, and the problem of secondary pollution is avoided.

The lid referred to in this invention may be any structure capable of providing a sealing effect in the art, including but not limited to a tear film, a tab lid, a tear tab, a stretch lid.

The present embodiment also has the following example.

On the basis of the present embodiment, if a conventional folding line arrangement is adopted, the situation as shown in fig. 9 and 10 will inevitably occur after folding. Fig. 9 shows a semi-finished container, the bottom of which is unsealed, the through hole 2 and the flow-through module are preset on the top of the semi-finished product, the purpose of the unsealed bottom is to fill the semi-finished product from the bottom after the flow-through module and other areas of the semi-finished product are sealed, and the semi-finished product is sealed after the bottom filling is finished.

In addition to the above examples, there are other examples such as a case where the top surface is defined into a non-planar shape (such as various different plane shapes and the like) according to a broken line, and thus the top surface is not a top surface in a conventional sense but is composed of a plurality of surfaces, and thus the through-hole 2 is not provided on the top surface in a conventional sense.

Example two

The present embodiment relates to a state of the packaging unit during manufacture, which state is understood differently from the semi-finished product in the first embodiment. The state is as follows: the packaging unit comprises a plate-shaped unit body and is characterized in that a circulation assembly is further arranged on the unit body and comprises a bottle nozzle, a through hole is formed in the unit body, and the bottle nozzle is arranged at the through hole and communicated with the through hole.

This state is a state that may occur during the process of preparing a container using the packaging unit in the first embodiment, and there may be a plurality of cases in which this state occurs, and this embodiment specifically describes one of them, but is not limited to this case: when the bottle needs to be filled from the top of the container, namely the bottle mouth 10, the rest surfaces of the container should be sealed in advance, the cover 4 of the circulation assembly cannot be prefabricated, the cover 4 needs to be additionally arranged at the bottle mouth 10 after the filling is finished, and the additional arrangement mode of the cover 4 can adopt any available prior art. That is, the cap is essential to this patent, and the absence of a cap in this state is merely representative of a state at some intermediate point in the process of preparing the container, and not the final state after the container is formed.

EXAMPLE III

This embodiment is a preferred solution of the first embodiment, and functions by replacing the mouth 10 with the neck 3. The neck 3 is tubular, and the tubular shape in the invention refers to a hollow and vertically through channel for the circulation of contents, which has the function similar to a pipeline. The cap 4 is used to open and close the neck. Although the neck is used instead of the mouth 10 in the present embodiment, it is sufficient that the neck is sealed by a cap only by the existing means, and the manner of sealing the neck by the cap may be various existing means, such as adhesion at the opening of the neck, etc. The packaging unit in this form provides a container which is more convenient for the user to drink and which also reduces the retention of contents of the container, particularly the less flowable semi-solid liquid contents.

Another modification is also present in this embodiment: the flow-through assembly further comprises a neck 3, the neck 3 being tubular. The neck 3 is arranged on the unit body 1 instead of the bottle mouth 10, the bottle mouth 10 is arranged at the top end of the neck, and the cover 4 is used for opening and closing the bottle mouth 10.

Preferably, the circulation component is fixedly connected to the through hole of the unit body 1 through the connecting piece 5, and the preferred embodiment includes three schemes, namely, a, the bottle mouth 10 is connected to the unit body through the connecting piece 5, b, the neck 3 is connected to the unit body through the connecting piece 5, c, the bottle mouth 10 is arranged at the top end of the neck, and the neck 3 is connected to the unit body 1 through the connecting piece 5.

It is noted that the connector may be of any known art, preferably an adhesive sheet. This preferred option is equally applicable to the first embodiment. The shape of the connecting member can be any shape that can be realized, including but not limited to square, round, oval, etc., and the material of the connecting member can be the same as that of the neck 3 or the mouth 10, or any other material that can be fixed to the unit body 1.

Example four

This embodiment is a preferable example of the first or third embodiment.

Taking the flow-through module with the neck 3 as an example, the specific way of fixedly connecting the flow-through module to the unit body 1 is to align the flow-through module with the through hole 2 from the bottom of the unit body 1 and insert the flow-through module upwards into the through hole 2, the flow-through module continues to move until the flow-through module extends out of the through hole 2, and when the neck 3 of the flow-through module extends out completely, the flow-through module is fixedly connected to the bottom of the unit body 1 (i.e. the bottom surface of the unit body 1 in the above-mentioned flat state) through the adhesive plate.

The mouth 10 of the first embodiment is similar.

EXAMPLE five

In the present embodiment, the shape and structure of the neck 3 can be selected from any reasonable shape and structure scheme according to the requirement. Preferably, the neck 3 may be of polyhedral geometry or of revolution. The polyhedron geometry structure can be preferably a prism structure or a prism-frustum structure, or other structures and shapes similar to the prism structure and the prism-frustum structure; the geometry of the rotating body may be preferably a cylindrical structure or a circular truncated cone structure, or other structures and shapes similar to the cylindrical structure or the circular truncated cone structure.

EXAMPLE six

This embodiment is a modification of the third embodiment.

The plurality of folding lines α shown in fig. 1 are only examples, and actually, in fig. 1, the remaining lines are folding lines except for the through hole 2. The folding line α shown in fig. 1 is only a preferred arrangement of the folding line, and the specific folding method and logic of the arrangement of the folding line can refer to the invention patent with patent name "a liquid food packaging container, packaging material", patent number 201721224296.0 (hereinafter referred to as prior patent), but the folding line α of the present embodiment is not limited to this way, and all folding ways that the container can be formed by the folding line can be applied to the present embodiment, so that they will not be described in detail in the invention.

In the third embodiment, the through-hole 2 is opened in a region divided into the top surface, which corresponds to the region in the prior art, i.e., the upper bottom surface 11. The upper bottom surface 11 is the top surface in the invention, where the through hole 2 is necessarily opened, but this area is divided by the folding lines, so that the size of the through hole 2 can fully occupy the whole area, i.e. the whole top surface, without changing the arrangement of the folding lines.

There is a case where the size limit of the through-hole 2 is the entire top surface, which can be understood as a subordinate concept of "the through-hole 2 is opened on the unit body 1" and also as a subordinate concept of "the through-hole 2 can be in the region divided into the top surface".

EXAMPLE seven

This embodiment provides a method of manufacturing a container using the packaging unit of the above embodiment, which also includes the manner by which the packaging unit is manufactured.
