The unit body a1 is provided with a series of folding lines, and is folded along the folding lines to form a container blank, at this time, the top of the container is open and uncovered, and the top end of the container has no folding ear, so that only a semi-finished product of the container can be counted, as shown in fig. 1. The unit cell a1 may be a single layer, but more often it is a multi-layer composite. The unit body B2 is also a combined structure and comprises a circulation component and a contact area 5, wherein the circulation component at least comprises a neck part 3 and a cover 4, the contact area 5 is arranged around the neck part 3 in a surrounding way, the neck part 3 is tubular, and the cover 4 is arranged at the top end of the neck part 3 and used for opening and closing the neck part 3; the flow-through element is intended to cover the top of the container half-finished product and is connected to the container half-finished product by means of a contact zone 5. Thus, a finished container is obtained.

The shape of the flow-through module can be varied, but should be provided with the following conditions: 1. the container can circulate the content in the container; 2. the flow-through assembly can completely cover the top opening of the semi-finished container to achieve sealing. The flow-through module meeting the above conditions may be of any suitable, rational shape or configuration, so that the suitable, possible, rational shape or configuration may be designed and selected according to the commercial requirements, as follows. For this purpose, the flow-through assembly comprises at least a neck 3 and a cap 4, the contact zone 5 being circumferentially arranged around the neck 3, the neck 3 being tubular, the cap 4 being arranged on top of the neck 3 and being adapted to open and close the neck 3.

The tubular shape in the invention refers to a hollow and vertically through channel for the circulation of the content, which plays a role similar to a pipeline.

The neck 3 shown in fig. 1 is shaped like a truncated pyramid and can be used to match a container with a quadrangular top opening, but the present embodiment is not limited thereto, and a truncated cone-like neck 3 or a cylindrical-like neck 3 can be applied to the present embodiment, and only a container adapted to the shape of the bottom surface of the neck 3 needs to be provided. Specifically, the shape and structure of the neck 3 can be any reasonable shape and structure scheme according to the requirement. Preferably, a polyhedral geometry or a rotator geometry may be used. The polyhedral geometry structure can also be a prism structure or a prism-frustum structure, or other structures and shapes similar to the prism structure and the prism-frustum structure; the geometrical structure of the rotating body may also 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 two

This embodiment is a first modification of the first embodiment.

In the first embodiment, the unit body B2 includes not only the flow-through member and the contact area 5, but also a cover 6 and an adhesive plate (not shown), and the neck 3 is fixed to the cover 6 by the adhesive plate. In which the cover 6 covers the top of the container blank, the neck 3, which in the first embodiment functions as a cover, is then mounted on the cover 6, and the cover 6 should also function as a seal in addition to the cover function. The covering 6 is provided with a through hole 7 for the neck 3 to communicate with. The neck 3 is connected to the cover 6 by means of an adhesive plate which is fixed around the through hole 7 in order to ensure that the neck 3 is in communication with the through hole 7. The contact area 5 is arranged around the edge of the cover 6, and the function of the contact area 5 is still fixed, but in the present embodiment, the fixed object is the cover 6.

The shape of the cover 6 may take any currently available configuration or shape. Such as flat, or other configurations, simply to provide a cover. The way in which the cover 6 seals with the top of the container blank via the contact zone 5 may be the same as the way in which the contact zone 5 seals with the top of the container blank as provided in the first embodiment, or it may be that the contact zone 5 is parallel to the top surface of the container blank, covering the top of the container blank from above, as shown in fig. 4.

This variant also has a preferred embodiment, where the neck 3 is preferably passed through the through hole 7 from below the cover 6 and extended from the through hole 7, and when the neck 3 is fully extended, the adhesive plate at the bottom of the neck is just contacted with the cover 6 and fixed, and preferably, the neck can be fixed and sealed by a heat sealing process, which can refer to the first embodiment.

EXAMPLE III

The present embodiment is a preferred embodiment of the first embodiment and the second embodiment, and the difference is that the circulation assembly further includes a bottle mouth 9, the bottle mouth 9 is disposed at the top end of the neck 3, and the cap 4 is used for opening and closing the bottle mouth 9. The mouth 9 may take any currently available configuration or shape, such as the most common form of a threaded exterior of the mouth, with the cap 4 sealing against it.

Example four

This embodiment is a first modification of the second embodiment, and is different in that a mouth 9 is used instead of the neck portion 3 in the second embodiment. The mouth 9 may be mounted, secured, sealed or otherwise formed with reference to the neck 3. The structure and shape of the mouth 9 can be referred to the third embodiment without any other special requirements.

EXAMPLE five

This embodiment is a second modification of the first embodiment.

In this embodiment, the difference from the first embodiment is that the bottom surface of the container blank is of unitary construction, i.e. the bottom surface of the container blank is intact, without a sealing line. The structure has attractive appearance and high practicability, the container of the structure has strong stability and high pressure bearing capacity, the leakage probability caused by the bonding line is reduced, the use of sealing materials such as sealing strips and the like is reduced, and the structure is energy-saving and environment-friendly. To achieve this effect, this can be obtained by way of example as follows:

1. by reasonably designing the crease or folding line on the unit body A1.

For example, refer to a utility model patent No. 201721224296.0 (hereinafter referred to as prior patent) entitled "a liquid food packaging container, packaging material", in which a container is made of a sheet material which is divided into respective sides intended to form the container by folding lines or creases, and to this embodiment, only the bottom surface is divided separately, and the entire bottom surface can be obtained after folding.

The modes for achieving the above effects cannot be exhaustive in the present embodiment, and therefore other existing modes capable of achieving the above effects can be taken as examples of the present embodiment.

EXAMPLE six

This embodiment is a first modification of the second embodiment.

There are two implementations of the contact region 5 as a one-piece structure.

The solution is a solution of the contact zone 5 folded in the longitudinal direction during installation.

Since the contact area 5 is arranged around the edge of the cover 6 and, as can be seen from the second embodiment, the contact area 5 should abut the container side wall, the contact area 5 should be parallel to the container side wall. From this, it is understood that the contact zone 5 can be oriented upward to achieve the parallel effect and can also be oriented downward to achieve the parallel effect, but the angle of the contact zone 5 is determined by the shape and angle of the inner wall of the container to be bonded. Taking the cover 6 as a circle or a square, if the contact region 5 is made of a soft material, the contact region 5 is easily folded at an angle 8 (as shown in fig. 6) when it is connected to the cover 6. The folded angle 8 should be sealed to avoid contamination.

The second option is the option of the contact zone 5 that can be directly bonded without folding.

The scheme is that the contact area 5 does not need to be folded, and the contact area is an integral structure formed by an annular body or continuous multi-section lines, and the scheme is suitable for the situation that the contact area 5 is made of hard materials. The structure can be directly arranged on the edge of the covering 6 for jointing without additional processing. The course of this contact zone 5 is determined by the course of the container side wall.

The first scheme and the second scheme are both of an integrated structure, and the difference between the first scheme and the second scheme is that the first scheme is a scheme for processing during container manufacturing, and the second scheme is a scheme for preprocessing before the container is manufactured. The effects of the two are theoretically the same, namely better structural strength, easy processing and easy installation are realized.

In the first variant, whether the contact zone 5 is directed upwards or downwards, there are two preferred ways, respectively, the dog-ear 8 being located on the opposite inside of the contact zone 5 and the dog-ear 8 being located on the opposite outside of the contact zone 5. Preferred mode of the opposite outer side can be seen in fig. 6, in which fig. 6 the contact area 5 forms a barrier-like structure, while the dog-ears 8 project outwards. In this case, the contact zone 5 can only adhere and seal against the inner wall of the container. While the contact area 5 is such that sealing can be facilitated, the bevel 8 can be folded and glued onto the contact area 5 beforehand. The contact area 5 and the folded angle 8 can be bonded and sealed, and the folded angle 8 and the side wall of the contact area 5 are fixed together, so that the sealing performance of the position where the folded angle 8 is located is ensured. Correspondingly, reference is also made to the above-described embodiment when the bevel 8 is situated relatively inside.

In the second alternative, the multi-segment or annular body is a continuous, monolithic structure that can be prefabricated in advance, so that the problem of the dog-ear 8 can be eliminated. Two preferred ways of forming the contact region 5 are to form a part of the neck portion 3, i.e. to form an integral structure therebetween, and the contact region 5 and the neck portion 3 are made of the same material. Secondly, the contact zone 5 is mounted on the cover 6, the combination of the neck 3 and the contact zone 5 at this time being similar to the shape of a rocket fairing, the neck 3 being the front cone section of the fairing and the contact zone 5 being similar to the cylinder section of the fairing. The contact region 5 may be made of the same material as or different from the neck portion 3.
