Detailed Description
The following is a detailed description of the embodiments of the present invention, and the technical solutions of the present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1 to 6, a high barrier container having contents 5 includes a container body 1 and a bottle cap 2. The walls of the container body 1 are made of a multilayer composite material by blow molding, at least one layer of which is EVOH. Increase the barrier effect of the container and prolong the shelf life.
The container body 1 comprises a cavity part 1a and a cover part 1b, and the cavity part 1a and the cover part 1b are connected through a first easy-tear structure 3.
Cavity portion 1a has a neck portion 1a3, neck portion 1a3 has first screw thread 1a1, cap portion 1b has second screw thread 1b1, and the screw thread provided inside cap 2 can be connected to first screw thread 1a1 and also to second screw thread 1b 1. After the container with the content 5 has been blown, the cap 2 is connected to the second thread 1b1 and screwed onto the outside of the cap 1b for use.
After the cap portion 1b is removed, the neck portion 1a3 on the chamber portion 1a forms an opening, the bottle cap 2 is connected with the first thread 1a1, screwed on the opening of the neck portion 1a3, and sealed by the bottle cap 2. The bottle cap 2 can be used for a plurality of times before the content 5 is not used up in time.
As shown in fig. 1 to 5, the cap portion 1b has a first connecting section 1b2 extending obliquely inward, the thickness of the first connecting section 1b2 is gradually reduced from outside to inside, and the inner end of the first connecting section 1b2 is connected to the constricted portion 1a 3. The necking part 1a3 has a second connecting section 1a2 extending obliquely inward, the thickness of the second connecting section 1a2 is gradually reduced from outside to inside, and the inner end of the second connecting section 1a2 is connected with the inner end of the first connecting section 1b 2.
An annular groove is formed between the first connecting section 1b2 and the second connecting section 1a 2. This annular groove is machined during the blow-moulding of the container body 1. The thickness of the connecting section of the annular groove can be gradually reduced from outside to inside through a tearing process in a blow molding process, and the thickness of the connecting section can also be gradually reduced from outside to inside through an extrusion process or a cutting process of a blow molding tool. After the integral blow molding is finished, the minimum thickness of the joint of the first connecting section 1b2 and the second connecting section 1a2 is 0.15mm-0.25mm, and the cover part 1b is easy to tear and remove. The lid portion 1b is easily opened and removed by screwing or pulling after breaking the first structure 3.
As shown in fig. 3, after the cavity portion 1a is blow molded, the content 5 is filled in the cavity portion 1 a. At the same time, the cap portion 1b and the constricted portion 1a3 are blow-molded to complete the container body 1 having the annular groove. The container body 1 is completely filled and sealed in an uncooled state after blow molding with the contents 5. Since the connection between the chamber portion 1a and the lid portion 1b is accomplished by the blow molding process, the content 5 is filled in the chamber portion 1a to form a completely sealed state without high-temperature sterilization again.
As shown in fig. 1 to 5, the container body 1 includes a sheet-like locking portion 1c, the locking portion 1c is located outside the cap portion 1b, and the locking portion 1c is connected to both the constricted portion 1a3 and the cap portion. The locking portion 1c reinforces the connection between the cap portion 1b and the constricted portion 1a3 before the cap portion 1b is removed.
The locking portion 1c and the constricted portion 1a3 are connected by the second tearable structure 4.
The locking part 1c has a third connecting section 1c1 extending outwards, and the thickness of the third connecting section 1c1 extending outwards is gradually reduced to form a knife edge shape. The thinnest thickness of the third connecting section 1c1 extending outward is 0.15mm-0.25mm, which makes it easy to tear the connection between the locking portion 1c and the receiving portion 1a and remove the lid portion 1 c.
The number of the locking portions 1c is one or two, and the number is selected as necessary to adjust the connection strength between the lid portion 1b and the cavity portion 1 a.
When the lid portion 1b of the container body 1 needs to be removed and the number of the locking portions 1c is one, the locking portion 1c is pulled upward, and the thinnest area of the first connecting section 1b2 is torn by the abutting force with which one end of the locking portion 1c abuts against the lid portion 1b, so that the lid portion 1b can be removed. In the case where the number of the locking portions 1c is two, the cap portion 1b can be removed by screwing the cap portion 1b with the locking portions to break the thinnest area of the second easy tear structure 4 and the first connecting section 1b 2.
As shown in fig. 3 or 6, after the cap portion 1b is removed, the closure 2 is removed from the outside of the cap portion 1b, connected to the first thread 1a1, and screwed onto the opening of the neck portion 1a 3. The bottle cap 2 can be used for a plurality of times before the content 5 is not used up in time.
As shown in fig. 1 or fig. 2, the side surface of the locking portion 1c has a plurality of convex points, which increases the friction force of the side surface of the locking portion 1c, facilitates the locking portion 1c to be manually turned or screwed, and avoids slipping.
In the above technical solutions, the wall of the container body 1 is made of a multi-layer composite material, and the composite material is replaced. Or the processing mode of replacing the annular groove is changed, so long as the easy-tearing structure in the technical scheme can be formed, and the change is within the protection scope of the utility model.
