Abstract
A double-layer container combination is suitable for containing fluid and comprises an outer container and an inner container, wherein the outer container defines a container space. The inner container comprises an inner container wall which is positioned in the container space and surrounds a containing space which is defined to contain the fluid, and an inner extending wall which extends upwards from the inner container wall. The inner extending wall is inseparably connected with the outer container and defines a communication channel communicated between the containing space and the outside. The inner container wall has a fixed wall section which is inseparably connected to the outer container, and a deformable wall section which is connected to the fixed wall section and is mainly made of a deformable material. The deformable wall section is capable of deforming to separate from the outer container to cooperate with changing the volume of the containing space when the fluid is sucked. The fixed wall section can not be separately connected with the outer container, so that the deformation amount of the inner container is limited, and the problem that the fluid cannot be sucked because the inner container plugs the suction pipe in the prior art can be solved.
Description
Technical Field

The inner container 12 is made of a deformable plastic material, and the top end portion is inseparably connected to the outer container 11 and defines a containing space 121 suitable for containing a fluid 13. The double container assembly is suitable for being used with a straw 14 inserted into the containing space 121.
When a user sucks the fluid 13 from the containing space 121, air can flow into the container space 111 through the air gap 112, and at this time, air pressure acts on the inner container 12 to cooperatively deform the inner container 12 and further push the fluid 13, so that the fluid 13 can be sucked out conveniently, however, after a period of use, since the amount of the fluid 13 is reduced, the deformation amount of the inner container 12 is increased accordingly, and the state shown in fig. 2 is assumed under the action of air pressure. In the situation shown in fig. 2, the inner container 12 will plug the bottom of the straw 14, and the fluid 13 will not be sucked out, which is an obstacle to use and is not improved.

Detailed Description
Referring to fig. 3 and 4, an embodiment of the double container assembly of the present invention includes a double container assembly 2 and a method of manufacturing the double container assembly 2. The method for producing the double container assembly will be described later.
The double container assembly 2 is adapted to contain a fluid 3. The kind of the fluid 3 is not particularly limited. The two-layer container assembly 2 comprises an outer container 4 and an inner container 5 located within the outer container 4 and having a profile matching the outer container 4 and partially bonded to the outer container 4.
The outer container 4 is made of a material which is hard and resistant to the change of air pressure without deformation, and in this embodiment is Polypropylene (PP), and includes an outer container wall 42 defining a container space 41 (see fig. 5), and an outer extension wall 43 extending upward from the outer container wall 42 and having a substantially hollow cylindrical shape. The outer extension wall 43 can be assembled with components such as a bottle cap or a cap, and thus the outer extension wall 43 can have a shape having threads or other shapes corresponding to those of the bottle cap or the cap, in addition to the shape shown in fig. 3 and 4.
The outer container wall 42 has a peripheral wall portion 44 with a top end connected to the outer container wall 43, and an outer bottom wall portion 45 extending downwardly from the peripheral wall portion 44.
The outer peripheral wall 44 is generally in the form of a hollow cylinder with a top portion tapered from bottom to top, and has a first wall section 441 and a second wall section 442 connected to each other diametrically opposite and extending axially upward and downward. The first and second wall sections 441, 442 are substantially circular in cross-section.
The outer bottom wall 45 has a first outer wall section 451 and a second outer wall section 452 extending from bottom to top in a front-to-rear direction D1. The first outer wall portion 451 is connected between the first outer wall portion 441 and the second outer wall portion 452, and defines an air inlet passage 453 communicating with the container space 41 and the outside in cooperation with the second outer wall portion 452. In the present embodiment, the air inlet 453 is an air slit located at the bottom and extending along a left-right direction D2. The second outer wall section 452 is connected between the second peripheral wall section 442 and the first outer wall section 451 in cooperation with the outer bottom wall portion 45 having a front-to-back longitudinal cross-section substantially in a V or U shape.
The inner container 5 is made of a deformable material, in this embodiment Polyethylene (PE), and includes an inner container wall 52 located in the container space 41 and surrounding a containing space 51 capable of containing the fluid 3, and an inner extension wall 53 extending upward from the inner container wall 52.
The inner container wall 52 has an inner peripheral wall portion 54 having a substantially circular ring-shaped cross section, and an inner bottom wall portion 55 extending downward from the inner peripheral wall portion 54.
The inner peripheral wall portion 54 is connected between the inner bottom wall portion 55 and the inner extension wall 53, is generally in the shape of a hollow cylinder with a top portion gradually reduced from bottom to top, and has a fixed wall section 541 and a deformable wall section 542 which are connected to each other in a diametrically opposite manner and extend axially upward and downward. The fixed wall section 541 is located on one of front and rear opposite sides of the intake passage 453 and inseparably connects the first peripheral wall section 441 of the outer container 4. The deformed wall section 542 is located on the other of the front and rear opposite sides of the intake passage 453 and can be separated from or abutted against the second peripheral wall section 442 of the outer container 4.
In the present embodiment, the cross sections of the fixed wall section 541 and the deformed wall section 542 are generally semicircular, that is, the fixed wall section 541 and the deformed wall section 542 have the same size, but in other embodiments of the present invention, the fixed wall section 541 is not smaller than the deformed wall section 542, that is, the fixed wall section 541 can be larger than the deformed wall section 542.
The inner bottom wall 55 and the inner peripheral wall 54 cooperate to define the containing space 51, and have a first inner wall 551 and a second inner wall 552 extending from bottom to top and back to back. The first inner wall section 551 is located substantially on one of the front and rear opposite sides of the inlet channel 453, is connected between the fixed wall section 541 and the second inner wall section 552, and is inseparably connected to the first outer wall section 451 of the outer container 4. The second inner wall section 552 is connected between the first inner wall section 551 and the deformed wall section 542 on substantially the other of the front and rear opposite sides of the inlet port 453, and can be separated from or abutted against the second outer wall section 452 of the outer container 4.
The bottom end left and right side portions of the second inner wall section 552 are inseparably connected to the outer bottom wall portion 45 of the outer container 4, and the middle portion thereof is separable from or in contact with the outer bottom wall portion 45.
The inner extension wall 53 is hollow cylindrical and has an outer surface inseparably bonded to the inner surface of the outer extension wall 43 to close the top of the container space 41 and define a communication passage 56 communicating between the containing space 51 and the outside and allowing the fluid 3 to be sucked out.
Referring to fig. 3 to 5, the inner container 5 can be changed from a containing state shown in fig. 3 and 4 to a using state shown in fig. 5 by using a suction tube 6.
In the accommodated state, the fixed wall section 541 and the first inner wall section 551 of the inner container 5 are respectively bonded to the first peripheral wall section 441 and the first outer wall section 451 of the outer container 4, and the deformed wall section 542 and the second inner wall section 552 of the inner container 5 are detachably abutted against the second peripheral wall section 442 and the second outer wall section 452 of the outer container 4.
When the user sucks the fluid 3 from the containing space 51 through the suction tube 6, the pressure in the containing space 51 will be temporarily reduced, and the deformed wall section 542 and the second inner wall section 552 of the inner container 5 are deformed to balance the pressure, so as to transform the volume of the containing space 51 and transform the inner container 5 into the use state shown in fig. 5.
In the use position, the deformable wall section 542 is separated from the second peripheral wall section 442 and is attached to the straw 6 in spaced relation to the fixed wall section 541, and the second inner wall section 552 is separated from the second outer wall section 452 for the most part, particularly the middle of the bottom end, but is still spaced apart from the first inner wall section 551, and the bottom ends are still adhered to the outer bottom wall 45 on both sides. Since the fixed wall section 541 and the first inner wall section 551 cannot be separated from the outer container 4, that is, are limited by the outer container 4 and cannot approach the deformed wall section 542 and the second inner wall section 552, respectively, the inner container 5 can be prevented from blocking the bottom opening of the suction pipe 6 due to excessive deformation, and the trouble that the fluid 3 cannot be sucked out through the suction pipe 6 cannot occur. The design of the second inner wall section 552 adhered to the outer bottom wall 45 at both sides of the bottom end thereof can ensure that the suction tube 6 is not excessively deformed and the air inlet channel 453 is well communicated with the container space 41, thereby ensuring that the gas can smoothly flow into the container space 41 and the inner container 5 can be well deformed.
Referring to fig. 3, 4 and 6, the double container assembly 2 can be manufactured by a method of manufacturing a double container assembly. The method for manufacturing the double-layer container combination comprises a step S1 of providing the container and a step S2 of squeezing the container.
In the container providing step S1, the outer container 4 and the inner container 5 are provided and bonded to each other. In the squeeze container step S2, the deformed wall section 542 and the second peripheral wall section 442 corresponding to each other are squeezed, and the second inner wall section 552 and the second outer wall section 452 corresponding to each other are squeezed, so that the deformed wall section 542 and the second inner wall section 552 can be separated from the second peripheral wall section 442 and the second outer wall section 452, respectively, and are not bonded, thereby obtaining the two-layered container assembly 2.
In the present embodiment, the design of the fixed wall section 541 is not smaller than that of the deformed wall section 542, so as to effectively reduce the deformation of the deformed wall section 542 and the second inner wall section 552 in the use state and ensure that the straw 6 is not blocked. In detail, even if the fixed wall section 541 and the first inner wall section 551 are slightly separated from the outer container 4 by repeated use, since the fixed wall section 541 is designed to be relatively large in size from the beginning, it is ensured that the problem of clogging of the suction pipe 6 due to excessive deformation of the deformable wall section 542 and the second inner wall section 552 does not occur.
As described above, in the double container assembly of the present invention, the fixed wall section 541 is inseparably connected to the outer container 4, so that the deformation of the inner container 5 is restricted to a certain extent, and the problem of the bottom of the straw being clogged due to the excessive deformation of the inner container can be solved, and therefore the object of the present invention can be achieved surely.
The above description is only an embodiment of the present invention, and the scope of the claims of the present invention is not limited thereto, and the equivalent modifications made by the contents of the claims and the description of the present invention are also intended to be covered by the scope of the claims of the present invention.
