Detailed Description

The invention will be further described with reference to specific embodiments.

In order to overcome the technical problem who solves among the background art, the utility model designs a manufacturing process of splendid attire container to corresponding splendid attire container has been made through this technology. The technical content of the present invention will be specifically described below with reference to different containers and corresponding different manufacturing processes.

It should be noted that, in this embodiment, the container refers to the inner container portion, and in daily use, a layer of decorating material is provided in addition to the inner container portion, and the container is located inside the decorating material. In actual use, the combination of the container and the decorative material can obtain a complete thermos cup, thermos bottle or stewing pot or other containers which can face the ordinary consumers.

In this embodiment, the decorative material may be a plastic shell or a film plated by a process, and the specific material may be selected according to the requirement.

[ EXAMPLES one ]

In this embodiment, the functional metal layer used is a silver material. The structure of the container and the corresponding manufacturing process will be described in detail below.

As shown in fig. 1, a container for containing liquid beverage; at least a first container body 100 is included, having at least:

a first stainless steel inner container which is provided with a first stainless steel inner container outer layer 110 positioned on the outer layer of the container and a first stainless steel inner container inner layer 120 positioned on the inner side of the first stainless steel inner container outer layer 110; the two layers form the stainless steel inner container in the existing double-layer thermos cup.

Therefore, as shown in fig. 6 to 9, in the present embodiment, a first vacuum layer 140 is disposed between the first stainless steel inner liner outer layer 110 and the first stainless steel inner liner inner layer 120; the first stainless steel liner outer layer 110 and the first stainless steel liner inner layer 120 have a first outer layer bottom region 111 and a first inner layer bottom region 121, respectively. Thus, in this embodiment, the first stainless steel liner is a stainless steel liner having both a bottom region and side regions.

In addition, in this embodiment, as shown in fig. 2, the container further includes a first functional metal layer 130, and the first functional metal layer 130 is specifically described by taking a silver material as an example in this embodiment.

In this embodiment, the first functional metal layer 130 is a silver material layer uniformly attached to the inner side of the first stainless steel inner container inner layer 120. The design has the advantages that the silver material can fully exert the corresponding sterilization and disinfection functions, and the cost is much cheaper than that of the silver material which is completely adopted for manufacturing because only one layer of silver material is needed and the required silver consumption is not much, and the waste of the silver material is reduced.

In the present embodiment, the first functional metal layer 130 has a first sidewall region 131 and a first bottom region, and the first sidewall region 131 and the first bottom region 132 are integrally formed; that is, in this embodiment, the first functional metal layer 130 is a unitary piece formed by a drawing process from a silver material sheet. Therefore, it is not necessary to connect the first sidewall area 131 and the first bottom area 132 by soldering as in the prior art, thereby causing problems of affecting the quality of the silver material and increasing the number of process steps, which reduces the production efficiency.

Therefore, in this embodiment, a silver material is attached to the inner side of the stainless steel inner container, so that the first container main body 100 having the silver inner container can be obtained.

Thus, in this embodiment, the first container body 100 is a container capable of containing liquid beverage. The liquid beverage can be tea or common purified water.

Further, if the first stainless steel inner container is set to be a cylindrical body, the first container body 100 is an inner container of a vacuum cup with a silver inner container, and then a decorative material is added on the basis, so that the first container body can be sold to the outside.

However, in actual processing, the size of the first functional metal layer 130, i.e., the silver material layer, must be smaller than the size of the first stainless steel inner container inner layer 120 at first, so that the first functional metal layer 130 can be placed in the first stainless steel inner container inner layer 120, but the first functional metal layer 130 and the first stainless steel inner container inner layer 120 need to be tightly attached to each other in the final product.

Therefore, it is necessary to stretch or expand the first functional metal layer 130 once, so that the connection between the first functional metal layer 130 and the first stainless steel inner container layer 120 is more tight after expansion.

In this embodiment, the first stainless steel inner layer 120 at least has:

an inner layer outer surface 122 corresponding to an inner surface of the first stainless steel inner bladder outer layer 110 and forming a first vacuum layer 140; and

an inner layer inner surface 123 corresponding to an outer surface of the first functional metal layer 130;

wherein, the inner surface 123 of the inner layer is formed with a plurality of connecting grooves 124 recessed toward one side of the outer surface 122 of the inner layer, and the first functional metal layer 130 at least partially extends into the connecting grooves 124 at the same time.

That is, the first functional metal layer 130, i.e., the silver material layer, is expanded and first abuts against the inner layer inner surface 123; the silver layer is then expanded further, and the silver layer can then extend into the connecting recess 124.

So that the first functional metal layer 130 and the first stainless steel inner container layer 120 are bonded more closely. The reason why the design is needed is that in practical use, because the first stainless steel inner container is relatively thin, the first stainless steel inner container may bulge when encountering high temperature, and the use is affected.

Also in this embodiment, the connecting groove 124 also has a venting function. The principle of function generation is as follows: before the first functional metal layer 130 is expanded, some air must exist between the first functional metal layer and the first stainless steel inner container layer 120, and the connecting groove 124 can also be a passage for exhausting the air. Therefore, when designing the connection groove 124, it is necessary to design the connection groove 124 in a structure having an opening at one end so that air can be finally discharged from the opening.

Of course, in the actual manufacturing process, the depth of the connecting groove 124 obtained by chemical etching may be designed to be larger than the expanded size of the first functional metal layer 130, so that the first functional metal layer 130 only enters the connecting groove 124, but a part of the space is reserved for storing a part of air when the air is not exhausted, so that the first functional metal layer 130 can be attached to the first stainless steel liner inner layer 120 as a whole.

The following detailed description describes a process for manufacturing a first container body according to an embodiment, which includes the following steps:

the method comprises the following steps: preparing a first stainless steel inner container outer layer, a first stainless steel inner container inner layer and a first functional metal layer;

wherein the shape of the first functional metal layer is matched with the inner layer of the first stainless steel inner container;

step two: arranging a first functional metal layer in the inner layer of the first stainless steel inner container; then placing the inner layer of the first stainless steel inner container into the inner side of the outer layer of the first stainless steel inner container;

step three: welding the inner layer of the first stainless steel inner container and the outer layer of the first stainless steel inner container, and vacuumizing the inner layer of the first stainless steel inner container and the outer layer of the first stainless steel inner container to form the first stainless steel inner container;

step four: heating and softening the first functional metal layer;

step five: and high-pressure gas is filled into the first functional metal layer, so that the first functional metal layer is expanded and tightly attached to the inner layer of the first stainless steel inner container.

It should be noted that in the manufacturing process, a plurality of connecting grooves 124 are formed in advance on the inner surface of the inner layer of the first stainless steel liner; the connecting groove 124 is used for the first functional metal layer to at least partially extend into the connecting groove 124 and be attached to the inner side surface of the inner layer of the first stainless steel liner in the fifth step. More specifically, the connecting grooves 124 are chemically etched in the raw material of the inner layer of the first stainless steel inner container 120 before it is rolled into a cylindrical blank.

In addition, in the first step, firstly, an outer liner stainless steel raw material, an inner liner stainless steel raw material and a first functional metal layer 130 raw material are respectively prepared;

then, the stainless steel raw material of the first outer-layer inner container is made into a first outer-layer stainless steel inner container, the section of the first outer-layer stainless steel inner container is U-shaped, and a first hole position for vacuumizing is reserved at the bottom of the first outer-layer stainless steel inner container;

then, the stainless steel raw material of the first inner layer inner container is made into a cylindrical first inner layer stainless steel inner container, and a base corresponding to the first inner layer stainless steel inner container is manufactured.

In addition, in the second step, after the first functional metal layer 130 is disposed in the first stainless steel inner container layer, the first stainless steel inner container layer and the corresponding base are welded; then, the first functional metal layer 130 and the first inner stainless steel liner are placed inside the first outer stainless steel liner, and the first inner stainless steel liner and the first outer stainless steel liner are welded.

It should be noted that, in this embodiment, the raw material of the first functional metal layer 130 is a silver material layer, and the raw material of the stainless steel of the outer liner and the raw material of the stainless steel of the inner liner may be the same or different. For convenience of description, in the present embodiment, the stainless steel material of the outer liner is the same as that of the inner liner.

In the first step, the first outer layer stainless steel inner container and the first inner layer stainless steel inner container may be formed by first rolling the first outer layer stainless steel inner container and the first inner layer stainless steel inner container into a tubular body having both ends penetrating through the first inner layer stainless steel inner container. The process of forming the first functional metal layer 130 is realized by a stretching process, and in practical use, a specific shape should be formed by stretching for many times, although the stretching times can be adjusted according to the complexity of the shape.

In addition, in the fourth step, the heating is realized by heating the water content by the boiler to generate steam, and spraying the steam from the air outlet to the inner side of the first functional metal layer 130. It is necessary to reverse the resulting first container body 100 over the air outlet.

In step five, the reason why the first functional metal layer 130 is expanded is that high-pressure gas needs to be input inside the first functional metal layer 130, and this process needs to apply high pressure to the first functional metal layer 130 while the first functional metal layer 130 is still in a relatively softened state, so that the problem that the silver material or the titanium material has relatively poor ductility and cannot be tightly attached to the first inner stainless steel liner can be overcome.

The softening in this embodiment means that the ductility of the first functional metal layer 130 and the second functional metal layer 230 is increased due to a higher temperature than that of the first functional metal layer.

Due to the design, the problem that the first functional metal layer 130 cannot be attached to the first stainless steel inner container inner layer 120 due to poor ductility of a silver material or a titanium material can be solved, and meanwhile, the problem that the silver material or the titanium material is not firmly connected enough due to attachment of a pure plane and a plane can be solved.

It should be noted that, although the first container body 100 is described as a thermos cup in this embodiment, in practical use, the first functional metal layer 130 can be inflated and attached to the first stainless steel liner inner layer 120 at one time as long as the shape is simple enough, and is not limited to the size or the thermos cup.

[ DEFORMATION EXAMPLE I ]

The present modification is basically the same as the first modification, but the difference is that in the first modification, the first functional metal layer 130 is a titanium material layer or a copper material layer, and the use of the titanium material layer can make the container have the effects of high strength, high temperature resistance, corrosion resistance and stable performance. The use of the copper material layer can lead the heat preservation performance of the vacuum cup to be better, and can also supplement trace elements and be beneficial to the body. Of course, other metal layers can be used as long as the corresponding metal layer gives good results in contact with water.

In the present modification, heating is performed in step six by heating the resistance rod, and the melting point of the resistance rod is higher than that of the titanium metal. The reason for this design is that titanium metal is chemically stable and has a relatively high melting point. Conventional steam cannot soften titanium metal.

The corresponding silver material is soft in texture and low in melting point, and the first functional metal layer 130 can be softened by using steam without actually melting the first functional metal layer 130.

[ example two ]

In the first embodiment, the first container body is a vacuum cup as a reference, and the vacuum cup is cylindrical as a whole and has small shape change, so that the first functional metal layer 130 can be realized only by one vacuum cup, and only needs to be expanded once in the process of inflation.

However, in actual use, as shown in fig. 3, the sectional shape of the thermo jug is an irregular curved surface, or at least has two circular arcs.

Because the ductility of the silver material or the titanium material is poor, if the silver material or the titanium material is adopted, high-pressure gas cannot be input once, and the silver material or the titanium material can be completely attached to the inner container of the stainless steel inner layer. In order to overcome the above technical problems, in the present embodiment, a thermo jug or tea stewing jug with a more complex shape can be formed by adding a second container main body 200 in addition to the first container main body 100 and then connecting the second container main body 200 and the first container main body 100 as shown in fig. 3. In this case, the first container body 100 is more merely a container for containing liquid beverage and is not referred to as a thermos cup.

The structure of the combined container will be described in detail below:

first, the structure of the second container body 200 is described, and as shown in fig. 4, it has at least:

a second stainless steel inner container having a second stainless steel inner container outer layer 210 positioned at the outer layer of the second container main body 200, and a second stainless steel inner container inner layer 220 positioned at the inner side of the second stainless steel inner container outer layer 210; in this embodiment, unlike the first stainless steel inner liner outer layer 110 and the first stainless steel inner liner inner layer 120, the second stainless steel inner liner outer layer 210 and the second stainless steel inner liner inner layer 220 both have no corresponding bottom regions, and only when both the second stainless steel inner liner outer layer 210 and the second stainless steel inner liner inner layer 220 are in a two-end through tubular structure, the lower end portions and the upper end portions of the second stainless steel inner liner outer layer 210 and the second stainless steel inner liner inner layer 220 are respectively welded. Thereby obtaining a second stainless steel inner container with two through ends.

Meanwhile, a second vacuum layer 240 is arranged between the second stainless steel inner container outer layer 210 and the second stainless steel inner container inner layer 220, and the second vacuum layer 240 is used for realizing heat preservation.

In addition to the second stainless steel inner container, in this embodiment, the second container body 200 further has a second functional metal layer 230, which is uniformly attached to the inner side of the second stainless steel inner container inner layer 220, having a second sidewall area 231,

and, the upper end of the second sidewall area 231 is formed with a cup opening portion 232, and the cup opening portion 232 is used for the user to drink water.

The following specifically describes the coupling structure between the first container body 100 and the second container body 200:

as shown in fig. 4 to 9, the first container body 100 has an external thread part 112 at the upper end thereof, and more particularly, an external thread part 112 at the outer side of the upper end of the first stainless inner container outer layer 110.

The second container body 200 has a female screw 221 at the lower end thereof, and more specifically, the female screw 221 is provided inside the lower end of the second stainless steel liner inner layer 220.

And, in the embodiment, the external thread part 112 is fitted with the internal thread part 221; in actual use, the first container body 100 and the second container body 200 are connected by screw threads. In order to maintain good sealing performance after connection, a first seal ring 300 is arranged between the lower end of the male screw part 112 and the lower end of the female screw part 221; and a second seal ring 400 is disposed between the upper end of the external thread portion 112 and the upper end of the internal thread portion 221.

Of course, in the second container main body 200, in order to make the second functional metal layer 230 more closely attached to the second stainless steel inner liner 220, the second stainless steel inner liner 220 also has the connection groove 124 formed on the surface thereof by chemical etching, and the second functional metal layer 230 is also attached to the connection groove 124 while being attached to the surface of the second stainless steel inner liner 220. It should be noted that the coupling groove 124 formed in the second container body 200 and the coupling groove 124 formed in the first container body 100 may have a desired texture or a different texture. Although the coupling groove 124 shown in fig. 10 is exemplified as a structure formed by the first container body 100, the coupling groove may be applied to the second container body 200.

As shown in fig. 7 and 9, a lower body upper flange 133 is disposed at the upper end of the first functional metal layer 130, and the lower body upper flange 133 is at least partially disposed at the upper side of the upper end surface of the first stainless steel inner container outer layer 110.

Similarly, as shown in fig. 6, a lower flange 234 is disposed at the lower end of the second functional metal layer 230, and the lower flange 234 is sandwiched between the second stainless steel inner liner 220 and the second seal ring 400. Referring to fig. 9, the upper end of the second functional metal layer 230 further has a cup rim flange 233, and the cup rim flange 233 extends outward to at least partially cover the upper end surface of the second stainless steel inner container.

Through the design, the first functional metal layer 130 and the second functional metal layer 230 can be tightly combined with the corresponding stainless steel parts to the maximum extent respectively, so that the stability and the service life of the container are improved.

The following will specifically describe the manufacturing process of the above-mentioned combined container:

the manufacturing process of the first container body 100 is as described in the first embodiment, and will not be described herein. The manufacturing process of the second container body 200 will be specifically described next. The method comprises the following specific steps:

step six: chemically corroding the surface, corresponding to the second functional metal raw material, of the second inner container stainless steel raw material on the second container main body, so that a plurality of connecting grooves 124 are formed on the corresponding surface of the second inner container stainless steel raw material;

step seven: preparing a stainless steel raw material of the second outer layer inner container, a stainless steel raw material of the second inner layer inner container and a second functional metal raw material into a cylindrical second stainless steel inner container outer layer, a second stainless steel inner container inner layer and a second functional metal layer;

step eight: welding the outer layer of the second stainless steel inner container and the inner layer of the second stainless steel inner container; forming a second functional metal layer by a stretching process;

placing the formed second functional metal layer in the second stainless steel inner container;

step nine: heating and at least softening the second functional metal layer;

step ten: high-pressure gas is filled into the second functional metal layer of the second container main body, so that the second functional metal layer is further expanded and at least partially extends into the connecting groove 124 and is attached to the inner side surface of the stainless steel inner container of the second inner layer;

step eleven: the first container body and the second container body are connected.

It is noted that in step eleven: extruding and forming external threads on the upper end of the first container body 100 obtained in the seventh step;

extruding and forming an internal thread at the lower end of the second container body 200 obtained in the fourteenth step;

and the first container body 100 is screwed into the second container body 200. The first sealing ring 300 and the second sealing ring 400 are also configured in advance during screwing, so that the sealing performance and the stability of connection can be improved.

Thereby obtaining the inner container of the thermos kettle or the inner container of the tea stewing kettle. The container in this embodiment is used for manufacturing various different shaped liners by adopting a two-stage recombination method.

[ DEFORMATION EXAMPLE II ]

In the second modification, the second functional metal layer 230 is a titanium material layer. The titanium material layer can ensure that the container has the effects of high strength, high temperature resistance, corrosion resistance and stable performance. In the present modification, the titanium material layer is also softened at a high temperature in step six, in accordance with the modification. Of course, a copper material layer or other metal layers may be used as long as the corresponding metal layer can provide a good effect in contact with water.
