All directional indicators in the present disclosure (such as upper, lower, top, and bottom … …) are only used to explain the relative position of the components of the packaging container in a specific posture (e.g., as shown in fig. 1). It is clear to the person skilled in the art that: if the particular gesture changes, the directional indication changes accordingly.

In addition, the descriptions related to "first", "second", "third", etc. in the present invention are only used for distinguishing different components, and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated.

The following describes specific embodiments of the present invention with reference to the drawings.

As shown in fig. 1, the packaging container 100 of the present invention includes a first container 1, a second container 2, and a cover 3, wherein the first container 1 is detachably connected to the second container 2, and the cover 3 is detachably connected to an upper portion of the first container 1. The first container 1 is used for containing a first material, preferably the first material is a solid material, and more preferably the first material is a dry powder material; the second container 2 is used for containing a second material, preferably a liquid material.

The packaging container 100 of the present invention will be described in detail below.

First container 1

As shown in fig. 2, the first container 1 includes an upper stopper 11, a first container body 12, and a lower stopper 13. The first container body 12 has a first opening 121 located at an upper portion of the first container body 12 and a second opening 122 located at a lower portion of the first container body 12. The upper plug 11 is for closing the first opening 121 of the first container body 12, and for detachably connecting with the first container body 12 at the first opening 121. The lower plug 13 is for closing the second opening 122 of the first container body 12 and for being detachably connected with the first container body 12 at the second opening 122.

The lower plug 13 includes a seal 14, the seal 14 for closing the second opening 122 of the first container body 12.

The seal 14 is preferably made of a soft material for ease of manufacture and piercing operations as described below. Wherein, the soft material can be but not limited to silica gel.

In consideration of the fact that the sealing member 14 made of soft material is easily deformed when receiving an external force, and thus easily causes the sealing member 14 to be displaced or come off from the first container body 12, the lower plug 13 of the present invention is further provided with a supporting member 15 for supporting the sealing member 14.

The specific structure and connection of the various components are described in more detail below.

As shown in fig. 2-4, the first container body 12 includes an annular outer rim 123 and an annular inner rim 128. Wherein the annular outer rim 123 and the annular inner rim 128 are formed in the following manner: an area of the outer peripheral wall of the first container body 12 that is upwardly spaced from the bottom is formed as an annular outer peripheral edge 123 that is recessed radially inwardly, and an inner peripheral wall of the first container body 12 that is adjacent to the bottom is formed as an annular inner flange 128 that extends radially inwardly. Preferably, as shown in FIG. 3, the upper edge of the annular outer rim 123 is at approximately the same height as the lower edge of the annular inner rim 128 to hold the support member 15 in place.

The annular outer periphery 123 is insertable into a second container 2, described later, and is provided with at least one substantially circumferentially arranged catch 124. The locking groove 124 is adapted to engage with a protrusion 25 (see fig. 10) on the second container 2 to be described later, so as to detachably connect the first container 1 and the second container 2. Preferably, the shape of the card slot 124 is substantially as follows: a vertical extension section 125 is formed by extending a certain distance obliquely upwards from the bottom edge of the annular outer periphery 123, and a circumferential extension section 126 is formed by extending a certain distance along the circumferential direction of the annular outer periphery 123, so that a substantially L-shaped clamping groove 124 is formed. In this way, the assembly and disassembly of the first and second containers 1, 2 can be easily achieved.

Further, as shown in fig. 2, a limit protrusion 127 is disposed near one end of the circumferentially extending section 126 of the card slot 124 close to the vertically extending section 125, and the limit protrusion 127 is configured to: after the first container 1 and the second container 2 are assembled, the movement of the protrusion 25 located at the circumferentially extending section 126 is restricted, thereby preventing the first container 1 and the second container 2 from being undesirably released after the first container 1 and the second container 2 are assembled.

As shown in fig. 5, the seal 14 further includes an annular seal body 141 and a circular septum 142. The diaphragm 142 is provided on the inner peripheral wall of the annular seal body 141, and is preferably provided at a position close to the lower edge of the inner peripheral wall of the seal body 141 and integrally provided with the seal body 141 for the sake of convenience of manufacture. The connection of the diaphragm 142 to the inner peripheral wall of the seal body 141 is provided with an annular groove 143, and the annular groove 143 is used for receiving a part of a support main body 151 described later to achieve tight engagement of the seal 14 with the support 15.

Further, as shown in FIG. 9, the diaphragm 142 is preferably of an upwardly domed configuration. By this arrangement, the first material in the first container 1 can be distributed around the diaphragm as much as possible, thereby preventing the first material from being excessively concentrated on the central portion of the diaphragm 142, which causes the diaphragm 142 made of soft material to be greatly stressed and deformed, and further preventing the diaphragm 142 from undesirably protruding from the bottom of the sealing member body 141.

Further, as shown in fig. 6 to 8, the diaphragm 142 is provided with a strength weakened region 1421. The arrangement of the strength-weakened region 1421 is not particularly limited in the present invention. Preferably radially disposed about the center of the diaphragm 142. In addition, the strength weakened region 1421 may also be formed by a plurality of weakness points 1422 spaced apart. In this way, it is not only convenient for the later-described piercing part 23 to break the diaphragm 142, but also it is ensured that the diaphragm is broken substantially uniformly along the predetermined strength weakened region 1421, thereby avoiding the problem of a decrease in the fluid communication effect due to the non-uniform breaking of the diaphragm.

It should be noted that:

the weakened strength region means that the mechanical strength (for example, shear strength, tensile strength, etc.) of the separator in this region is lower than the mechanical strength of the separator not in this region, and is easily broken by the piercing portion 23 described later. Preferably, for ease of manufacture and cost reduction, the weakened area of strength (weak point) in this embodiment is achieved by reducing the thickness of the diaphragm in that area.

In addition, the piercing part of the present invention is not limited to piercing the diaphragm, and any member that breaks the sealing effect of the diaphragm on the first container by causing the diaphragm to break (including partial breakage) by the action of the piercing part may be referred to as a piercing part.

As shown in fig. 2 to 5, the support 15 includes a ring-shaped support body 151. A protruding ring 152 and an annular clamping groove 153 adjacent to the protruding ring 152 are arranged on the upper edge of the outer peripheral wall of the support main body 151. The collar 152 and the annular groove 153 are snap-fit with the annular inner flange 128 formed on the inner peripheral wall of the first container body 12. In order to ensure the supporting strength of the supporting member 15 for the sealing member 14 and to ensure that the supporting member 15 is easily engaged with the annular inner flange 128 of the first container body 12, the supporting member 15 is preferably made of PE in this embodiment.

As shown in fig. 2, the first container 1 further comprises a protective cover 4 when the first container 1 is not assembled with the second container 2. By providing the protective cap 4, on the one hand, the seal is protected from external contamination and, on the other hand, the material in the first container 1 is prevented from accidentally leaking out of the membrane 142 of the seal 14. Further, a second annular locking groove 41 is provided on the inner peripheral wall of the cover 4. The second annular engaging groove 41 is engageable with an annular protrusion 144 provided on the outer peripheral wall of the sealing member body 141.

Second container 2

As shown in fig. 10 and 11, the second container 2 includes a sealing cap 5, a second container body 21, an annular flange 22, and a puncturing part 23.

Wherein the annular flange 22 and the punctured portion 23 are formed by: a cylindrical annular flange 22 extends upward from the outer periphery of the top wall of the second container body 21. A third opening 24 is provided at an arbitrary position on the top wall of the second container body 21, and a cylindrical puncture portion 23 extends upward on the outer peripheral edge of the third opening 24. Preferably, the third opening 24 is provided in the centre of the top wall of the second container 2, and the shape and size of the pierced portion 23 are adapted to the shape and size of the aforementioned septum 142.

In order to ensure the mixing efficiency of the first material in the first container 1 and the second material in the second container 2 when mixing is required, the inner diameter of the puncture part 23 is preferably 1/2-2/3 of the outer diameter of the top wall of the second container body 21 (i.e. the outer diameter of the annular flange 22); more preferably, the inner diameter of the puncturing part 23 is 2/3 of the outer diameter of the top wall of the second container body 21.

As mentioned above, the annular flange 22 is provided with at least one protrusion 25 on its inner circumferential wall, which protrusion 25 is adapted to snap fit with a snap groove 124 provided on the first container 1.

As shown in fig. 3 and 10, the annular flange 22 and the puncturing portion 23 have an annular gap 26 therebetween. When the first container 1 and the second container 2 are assembled, the annular outer peripheral edge 123 of the first container body 12 is inserted downward into the annular gap 26, and eventually the lower edge of the annular outer peripheral edge 123 abuts on the top wall of the second container body 21. At this time, the diaphragm 142 is broken by the reaction of the upper edge of the puncturing part 23, that is, the sealing effect of the sealing member 14 against the second opening 122 is broken by the puncturing part 23. As a result, the first material contained in the first container 1 enters the interior of the second container 2 through the second opening 122 and the third opening 24 (i.e., the connecting passage of the first container and the second container) under the action of gravity, and the mixing of the first material and the second material is realized.

As shown in fig. 3, by the above structure, at least a portion of the damaged diaphragm 142 can be limited in the annular gap between the outer peripheral wall of the puncturing part 23 and the inner peripheral wall of the supporting part 15, so as to avoid the damaged diaphragm 142 from being located at the connecting channel between the first container 1 and the second container 2 in an uncontrolled manner to block the channel, thereby affecting the mixing effect of the materials and being not beneficial to the pouring of the mixture of the materials in the later use.

Further, as shown in fig. 10, the puncturing part 23 further includes an annular rib 27 provided on an outer peripheral wall thereof, and an outer diameter of the annular rib 27 substantially coincides with an inner diameter of the aforementioned support main body 151. With this arrangement, on the one hand, the user can let the piercing part 23 enter the inside of the lower plug 13 without applying a large force; on the other hand, during the assembly process, the annular rib 27 always abuts the diaphragm 142 against the inner circumferential wall of the support main body 151, thereby preventing the first material in the first container 1 from leaking to the outside from the gap between the puncture portion 23 and the inner circumferential wall of the support main body 151; in the third aspect, in the unassembled state of the first container 1 and the second container 2, the annular rib 27 engages with the annular groove 51 provided on the inner peripheral wall of the seal cover 5, so that the seal cover 5 seals the third opening 24.

Before explaining the assembly (use) method of the present invention, it is to be explained that: the first container 1 itself, as shown in fig. 2, is already in an assembled state before being assembled with the second container 2, and likewise the second container 2 itself, as shown in fig. 10, is already in an assembled state before being assembled with the first container 1.

The method of assembling (using) the packaging container 100 of the present invention will be briefly described below with reference to fig. 1 to 12.

First, the user removes the protective cap 4 from the bottom of the first container 1 pre-filled with the first material and the sealing cap 5 from the top of the second container 2 pre-filled with the second material.

Next, the annular outer periphery 123 of the first container 1 is inserted into the annular gap 26 between the annular flange 22 and the puncturing portion 23 of the second container 2, and the circumferential position of the vertically extending section 125 of the catching groove 124 on the annular outer periphery 123 is substantially aligned with the circumferential position of the protrusion 25 on the annular flange 22, and the first container 1 is pressed downward (in the downward pressing process, the diaphragm 142 is gradually broken by the reaction force of the puncturing portion 23, and mixing of the first material and the second material is achieved) until the lower edge of the annular outer periphery 123 abuts against the bottom wall of the second container body 21.

The first container 1 is then rotated so that the projection 25 passes from the vertically extending section 125 into the circumferentially extending section 126, completing the snap connection (assembly) of the first container 1 to the second container 2.

It should be noted that: the above assembling method is a schematic assembling method of the packaging container of the present invention. It is clear to the person skilled in the art that: the packaging container may be assembled in any manner, including: for example, the user pushes the second container upward into the first container, and rotates the second container after the second container reaches the predetermined position of the first container, and finally, the snap-fit connection (assembly) of the first container and the second container is completed.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. The scope of the claims is to be accorded the broadest interpretation so as to encompass all such modifications and equivalent structures and functions.
