Description

Technical Field

[0001] This invention belongs to the field of product packaging technology, and in particular to packaging containers and packaging compositions thereof that can achieve internal puncture to release contents. Specifically, it relates to a well-sealed internal puncture cap and a packaging container having the same. Background Technology

[0002] In modern society, consumers have increasingly higher demands for product quality, convenience, and safety. In daily life, especially in the food, pharmaceutical, and cosmetic sectors, it is often necessary to package two or more ingredients separately to prevent chemical reactions or quality degradation during long-term storage and transportation. Therefore, consumers tend to choose packaging products with the following characteristics:

[0003] (1) Safety: It is necessary to ensure the isolation of different components to avoid cross-contamination;

[0004] (2) Convenience: It is easy to operate when using it, without complicated steps or special auxiliary tools, and saves time and effort;

[0005] (3) Functionality: It can effectively protect the product ingredients and maintain stable effects.

[0006] Currently, many traditional packaging solutions fail to fully meet the aforementioned needs, leading to problems such as cross-contamination of components, degradation and ineffectiveness of components before combination, and the need for complex mixing operations. Furthermore, they result in a poor user experience. Some products capable of component-separate packaging either employ simple packaging devices that cannot effectively separate and seal the components, or have overly complex structures with numerous parts and cumbersome assembly, causing inconvenience to product manufacturers and consumers. Therefore, this application addresses market demands and the shortcomings of existing technologies by proposing a new packaging container. Its design features include the ability to independently seal and mix multiple materials as needed, ensuring product safety, effectiveness, and convenience during use. The user (or operator) can easily open the packaging container by hand or with the aid of a simple, readily available rod. Summary of the Invention

[0007] The purpose of this invention is to solve the above-mentioned existing problems and provide a well-sealed inner puncture cap and a packaging container having it, which allows two independently sealed materials to be easily and quickly mixed together. The structure is compact, the operation is simple and labor-saving.

[0008] The above objective is achieved by the following technical solution:

[0009] A well-sealed internal puncture cap is provided for holding a first material, which is a solid or liquid. A packaging container for holding a second material, which is a liquid, is provided corresponding to the cap. The packaging container is bottle-shaped and includes a bottle body, a bottle neck, and a bottle mouth. The bottle mouth is provided with an external thread. The cap is assembled onto the packaging container by threaded connection.

[0010] Its features are:

[0011] The capping body includes a main cap, a secondary cap, and a puncture body. The main cap is used to hold the first material and is connected to the bottle body by threads. The puncture body is located inside the main cap. The secondary cap is located above the main cap and the puncture body.

[0012] The main cap includes a cap cylinder and a cap edge. The cap cylinder is a cylindrical shape with an open top and a closed bottom plane. The upper outer wall of the cap cylinder is provided with an external thread for connecting the secondary cap, and the bottom is provided with a half cap for being punctured by the puncture body and releasing the first material. The half cap is circular and integrally formed with the bottom of the cap cylinder. The half cap constitutes part of the bottom of the cap cylinder. A puncture guide groove with a thickness less than the thickness of the bottom of the cap cylinder is provided at the connection between the half cap and the bottom of the cap cylinder.

[0013] The cap edge is located on the outer wall of the cap cylinder and is in the shape of a snap cap. The cap edge is provided with an internal thread for connecting the packaging container and is adapted to the external thread of the bottle at the bottle mouth of the packaging container.

[0014] The inner wall of the cover cylinder is provided with longitudinally arranged baffles, with 4 to 10 baffles, and all baffles are distributed on the inner wall of the cover cylinder at an average spacing.

[0015] The secondary cover is in the shape of a snap-on cap and includes a secondary cover wall, a secondary cover bottom, and a secondary inner cover. The inner wall of the secondary cover wall is provided with an internal thread, which is used to establish a threaded connection between the secondary cover and the main cover. The secondary inner cover is located on the inner wall of the secondary cover bottom and is cylindrical. The inner wall of the secondary inner cover is provided with a piercing internal thread, which is used to establish a threaded connection between the secondary cover and the piercing body.

[0016] The bottom of the secondary cover is equipped with a sealing ring, which is aligned with the upper edge of the main cover's cover cylinder and is used to establish a sealed connection between the secondary cover and the main cover.

[0017] The puncture body is cylindrical, with an inclined spike at the bottom. The upper part of the outer wall of the puncture body is provided with external puncture threads, and the middle part is provided with 2-6 blocks.

[0018] When the puncture body is placed inside the main cap and the upper part of the puncture body is assembled and connected with the inner cover of the secondary cap, the stop block can abut against the stop strip on the inner wall of the cap cylinder.

[0019] The rim of the lid is provided with a rubber pad, which is located at the bottom of the rim and is used to create a tight seal between the main lid and the packaging container.

[0020] The cross-section of the baffle is wedge-shaped. The baffle includes a vertical surface and a slope. The vertical surface is perpendicular to the inner wall of the cover cylinder. One side of the slope is connected to the inner wall of the cover cylinder, and the other side is connected to the side of the vertical surface away from the inner wall of the cover cylinder.

[0021] The baffle has a directional bend, which is convex in shape. The directional bend includes a first bend segment and a second bend segment. The first bend segment and the second bend segment, the first bend segment and the baffle, and the second bend segment and the baffle are all connected by smooth transitions.

[0022] The length of the first bend is greater than the length of the second bend.

[0023] The sub-cover is provided with a hook, the upper end of which is fixed to the bottom of the sub-cover and the lower end is free. The lower end of the hook is provided with a barb.

[0024] The upper end of the puncture body is provided with a hook plate that is adapted to the barb of the hook. The hook plate is fixed to the top of the puncture body and has a hook hole in the middle that allows the barb to pass through.

[0025] The hook is a spiral made of elastic material. The barb includes a hook body and barbs. The hook body is made of rigid material, and the barbs are made of a material with a deformation capacity greater than that of the hook but less than that of the hook body.

[0026] The hook plate is a flat disc, with a hook bag at the hook hole. The hook bag and the hook plate together form a sealing body to isolate the barb from the inner cavity of the puncture body.

[0027] The sub-cover is provided with a pull ring, which is located on the outer side of the sub-cover wall;

[0028] The pull ring includes a wristband and a lever ring. The wristband is made of elastic material and its deformation range is less than 150%, while the lever ring is made of rigid material.

[0029] The wristband is oval-shaped and can accommodate one or two of the user's fingers, while the bar ring is round with a diameter of 8-10 millimeters.

[0030] A packaging container having the aforementioned well-sealed inner puncture-resistant cap, characterized in that:

[0031] The bottleneck is a tall, narrow cylinder. When the main cap is assembled and connected with the packaging container, the bottom of the bottleneck is flush with the bottom of the main cap cylinder, or the bottom of the bottleneck extends beyond the bottom of the cap cylinder.

[0032] The beneficial effects of this invention are as follows:

[0033] (1) Easy mixing: When users open the packaging container or twist the cap, the liquid can be easily mixed as needed, providing a more convenient user experience;

[0034] (2) Quality assurance: Independent matrix storage effectively avoids cross-contamination, ensuring the consistency of quality and activity of each component;

[0035] (3) Easy to carry: Lightweight structural design, suitable for travel and outdoor use;

[0036] (4) Reduced risk of contamination: The closed structure ensures hygiene during storage and solves many safety hazards of traditional packaging containers. Attached Figure Description

[0055] Example 1.

[0056] This embodiment provides a well-sealed internal puncture cap 10 for holding a first material, which is either solid or liquid. Specifically, the first material that needs to be mixed with liquids such as water in the packaging container (in this embodiment and other embodiments, the structure and function of the packaging container are specifically shown using a bottle, and the two are equivalent) is sealed and placed into the cap 10.

[0057] like Figure 1-3 As shown, a packaging container, namely a bottle body 20, is provided corresponding to the capping body 10 for holding a second material. This bottle body 20 holds water or other second materials. Specifically, the packaging container is bottle-shaped and includes a bottle body 23, a neck 22, and a bottle mouth 21. The bottle mouth 21 has an external thread 24, and the capping body 10 is threaded onto the packaging container. This embodiment does not limit the specific structural shape or volume of the bottle body 20, as long as it has a threaded interface compatible with the capping body 10. Furthermore, the capping body 10 can be manufactured in various specifications to meet the needs of using the two materials together.

[0058] The capping body 10 described in this embodiment includes a main cap 50, a secondary cap 30, and a puncture body 40. The main cap 50 is used to hold the first material and is connected to the bottle body 20 by threads. The puncture body 40 is disposed inside the main cap 50. The secondary cap 30 is disposed on the upper part of the main cap 50 and the puncture body 40. The main cap 50, the secondary cap 30, and the puncture body 40 are all designed as separate parts, that is, independent of each other, but can be assembled together in use. Basically, the main cap 50 is threaded to the bottle body 20, and the upper end of the puncture body 40 is threaded to the secondary cap 30. When the secondary cap 30 is threaded onto the main cap 50, the puncture body 40 is also placed inside the main cap 50, completing the assembly.

[0059] Specifically, the main cover 50 includes a cover cylinder 51 and a cover edge 52. The cover cylinder 51 is a cylindrical shape with an open top and a closed bottom plane. The upper outer wall of the cover cylinder 51 is provided with an external thread 55 for connecting the secondary cover 30, and the bottom is provided with a half cover 57 for being punctured by the puncture body 40 and releasing the first material. The half cover 57 is circular and integrally formed with the bottom of the cover cylinder 51. The half cover 57 constitutes part of the bottom of the cover cylinder 51. The connection between the half cover 57 and the bottom of the cover cylinder 51 is provided with a puncture guide groove 58 with a thickness less than the thickness of the bottom of the cover cylinder 51. The semi-cap 57 can be understood as a circular indentation pressed into the bottom circular surface of the cap cylinder 51 of the main cap 50 by means of extrusion, hot stamping, etc., forming a concave guide groove corresponding to the inclined tip of the puncture body 40. When the puncture body 40 is pushed down and guided to the bottom surface of the cap cylinder 51, the tip of the puncture body 40 can abut in this puncture guide groove 58, and when the puncture body 40 continues to press down or rotate, the tip can puncture the bottom of the cap cylinder 51 along the puncture guide groove 58. The reason for adopting the above structural design is that the two materials placed in the cap body 10 and the bottle body 20 are separately and independently sealed in a set of packaging containers before use. The two materials need to be kept sealed and separated before use, and adapt to remain in their original isolated state during operations including transportation, transfer, and placement. Therefore, the capping body 10 needs to withstand a certain amount of external or internal pressure to prevent leakage of the first material. Among the structural components of the capping body 10, the bottom of the cap cylinder 51, which will be punctured later, is a relatively weak link. Therefore, this embodiment uses a thicker and more stable material and structure than conventional existing similar structures. However, this also makes puncturing the bottom of the cap cylinder 51 difficult. Conventional puncture operations may result in small opening of the half-cap 57, deviation of the puncture body 40, and damage to the tip, leading to insufficient release of the first material or even failure to release it. In this embodiment, the puncture guide groove 58 can confine the tip of the puncture body 40 to a concentrated stress point (or line), making it easier to achieve a stable puncture.

[0060] The cap rim 52 is located on the outer wall of the cap cylinder 51 and is in the shape of a snap-on cap. The cap rim 52 has an internal thread 56 for connecting the packaging container and is adapted to the external thread 24 of the bottle mouth of the packaging container. The cap rim 52 is used for threaded connection to the bottle body 20 and can adopt a conventional structure, which will not be described in detail.

[0061] The inner wall of the cover cylinder 51 is provided with longitudinally arranged baffles 53. There are 4 to 10 baffles 53, preferably 8, and all baffles 53 are distributed on the inner wall of the cover cylinder 51 at an average spacing.

[0062] The secondary cover 30 is in the shape of a snap-on cap and includes a secondary cover wall 32, a secondary cover bottom 33, and a secondary inner cover 31. The inner wall of the secondary cover wall 32 is provided with an internal thread 35, which is used to establish a threaded connection between the secondary cover 30 and the main cover 50. The secondary inner cover 31 is located on the inner wall of the secondary cover bottom 33 and is cylindrical. The inner wall of the secondary inner cover 31 is provided with a piercing internal thread 36, which is used to establish a threaded connection between the secondary cover 30 and the piercing body 40. The secondary cover bottom 33 is provided with a sealing ring 34, which is aligned with the upper edge of the cover cylinder 51 of the main cover 50 and is used to establish a sealed connection between the secondary cover 30 and the main cover 50.

[0063] The puncture body 40 is cylindrical, with an inclined spike at the bottom. The upper part of the outer wall of the puncture body 40 is provided with an external puncture thread 42, and the middle part is provided with 2-6 stops 41, preferably 4. When the puncture body 40 is placed inside the cover cylinder 51 of the main cover 50, and the upper part of the puncture body 40 is assembled and connected with the inner cover 31 of the secondary cover 30, the stops 41 can abut against the baffle strip 53 on the inner wall of the cover cylinder 51.

[0064] Regarding the threads provided on the aforementioned components, such as Figure 2 As shown, the setup will be configured according to the following description and functional implementation:

[0065] (1) The internal thread 56 and external thread 24 between the main cap 50 and the bottle body 20: According to common practice, the thread realizes the sealing connection between the main cap 50 (that is, the entire cap body 10) and the bottle body 20. The thread is realized by conventional technology, which is to tighten clockwise and loosen counterclockwise.

[0066] (2) The inner thread 35 and the outer thread 55 between the secondary cover 30 and the main cover 50: According to common practice, this thread realizes the sealing connection between the main cover 50 and the secondary cover 30. This thread is achieved by conventional technology, which tightens clockwise and loosens counterclockwise.

[0067] (3) The internal piercing thread 36 and the external piercing thread 42 between the secondary cover 30 and the piercing body 40: This thread is used to control the lifting and lowering action of the piercing body 40 by rotating the secondary cover 30. That is, when the secondary cover 30 rotates clockwise, the piercing body 40 will rise towards the secondary cover 30 due to the restriction of the thread; conversely, when the secondary cover 30 rotates counterclockwise, the piercing body 40 will descend away from the secondary cover 30. Of course, when the secondary cover 30 rotates, the piercing body 40 cannot rotate exactly the same as the secondary cover 30. In this case, the piercing body 40 will not be able to achieve lifting and lowering movement relative to the secondary cover 30. Therefore, the stop 41 provided on the piercing body 40 needs to contact the stop strip 53 on the inner wall of the main cover 50 cover cylinder 51 to restrict the rotation operation of the piercing body 40, as described below.

[0068] The cover edge 52 is provided with a rubber pad 54, which is located at the bottom of the cover edge 52 and is used to form a tight connection between the main cover 50 and the packaging container.

[0069] like Figure 4 , 5 As shown, the cross-section of the baffle 53 is wedge-shaped. The baffle 53 includes a vertical surface 531 and a slope surface 532. The vertical surface 531 is perpendicular to the inner wall of the cover cylinder 51. One side of the slope surface 532 is connected to the inner wall of the cover cylinder 51, and the other side is connected to the side of the vertical surface 531 away from the inner wall of the cover cylinder 51. Corresponding to the above description of the lifting and lowering action of the puncture body 40 driven by the secondary cover 30, the stop bar 53 abuts against the stop block 41 to restrict the rotation of the puncture body 40 along with the secondary cover 30. That is, when the secondary cover 30 rotates counterclockwise, the puncture body 40 needs to descend to puncture the bottom of the cover cylinder 51. Therefore, at this time, the stop bar 53 should strictly restrict the stop block 41 from crossing the stop bar 53, that is, the stop block 41 contacts the vertical surface 531 of the wedge-shaped stop bar 53. Because the stop block 41 is restricted by the stop bar 53, the puncture body 40 is forced by the power transmitted by the thread of the secondary cover and can only descend longitudinally along the cover cylinder 51 to further achieve puncture. However, when the puncture body 40 is initially assembled into the secondary cover 30, and when the secondary cover 30 and the puncture body 40 are assembled together into the cover cylinder 51 of the main cover 50, the secondary cover 30 will be threadedly connected to the main cover 50 by rotating clockwise. At this time, the stop bar 53 cannot, or at least cannot completely restrict the stop block. 41 crosses the stop bar 53. Therefore, in this case, the stop block 41 should contact the slope 532 of the wedge-shaped stop bar 53. When the external torsional force applied by the sub-cover 30 is greater than the friction between the stop block 41 and the slope 532 of the stop bar 53, the stop block 41 will cross the stop bar 53, thereby achieving at least two technical effects: First, the sub-cover 30 can continue to rotate clockwise and achieve a sealed connection with the main cover 50. Second, because the stop block 41 (i.e., the puncture body 40) is subjected to a certain frictional force, when this force is greater than the friction between the internal puncture thread 36 and the external puncture thread 42 of the puncture body 40 and the sub-cover 30, the puncture body 40 will be pushed by the stop block 41 to further rotate into and rise towards the sub-cover 30, and may rotate to the bottom of the sub-cover. This can ensure sufficient distance between the tip of the puncture body 40 and the puncture groove at the bottom of the cover cylinder 51 to prevent the half cover 57 from being accidentally punctured and opened.

[0070] Example 2.

[0071] like Figure 4 , 5As shown, based on the above embodiment, the baffle 53 in this embodiment is provided with a deflection bend 60, which is convex in shape. The deflection bend 60 includes a first bend segment 61 and a second bend segment 62. The first bend segment 61 and the second bend segment 62, the first bend segment 61 and the baffle 53, and the second bend segment 62 and the baffle 53 are all connected by smooth transitions. In the above embodiment, the baffle 53 is straight and arranged longitudinally on the inner wall of the cap 51. Therefore, when the block 41 on the outer wall of the puncture body 40 is forced to descend, it is limited by the baffle 53 and can only descend in a straight line along the baffle 53. As a result, the tip of the puncture body 40 will act on a certain point of the circular puncture guide groove 58 around the half cap 57, and it can be considered as a one-way pushing and no moving or pulling action. Therefore, the puncture effect of the puncture body 40 on the half cap 57 is not good. It may be necessary to apply a greater torsional force outside the secondary cap 30 (while applying a reaction force on the main cap 50), making the packaging container difficult to open and use, affecting the user experience.

[0072] In this embodiment, based on the aforementioned embodiment, the structure of the baffle 53 is improved by changing a certain section in the middle of the baffle 53 into a convex shape, forming an arc-shaped or conical, smoothly transitioning bend 60. When the baffle 41 moves to the bend 60, the bend 60 will guide the baffle 41 to move obliquely in both directions. As a result, the puncture body 40 will also generate a certain degree of forward and reverse spiral rotation. This structure can enable the tip of the puncture body 40 to generate a reciprocating puncture and cutting action along the puncture guide groove 58 (i.e., circumferential) within the puncture guide groove 58. The reciprocating puncture and cutting action can be repeated multiple times by controlling the rotation direction of the sub-cover 30. This makes it relatively easier to puncture the half-cover 57 than in the aforementioned embodiment, and significantly reduces the degree of external force applied by the user, thus improving the user experience.

[0073] Furthermore, the aforementioned deflection bend 60 can protrude towards the vertical surface 531 of the retaining strip 53, or it can protrude in the opposite direction towards the slope 532. The difference between the two is that when the deflection bend 60 protrudes towards the vertical surface 531, the tip of the puncture body 40 will rotate in a spiral direction opposite to the force applied by the sub-cap 30 (counterclockwise), which may weaken the puncture force; while when the deflection bend 60 protrudes towards the slope 532, the spiral rotation direction of the tip of the puncture body 40 is consistent with the rotation direction of the sub-cap 30, because the sub-cap 30 and the puncture body 40 are connected... The pitch of the piercing internal thread 36 and the piercing external thread 42 is greater than the pitch of the cover internal thread 35 and the cover external thread 55 between the sub-cover 30 and the main cover 50. That is, under the same rotation arc, the travel distance of the piercing body 40 is greater than the travel distance of the sub-cover 30. Therefore, compared with the above-mentioned case where the deflection bend 60 protrudes towards the vertical surface 531, when the deflection bend 60 protrudes towards the slope surface 532, the tip of the piercing body 40 will pierce and cut the half cover 57 with a greater torque, which is more effortless for the user who applies external force.

[0074] Furthermore, this embodiment defines the location of the deflection bend 60 as follows.

[0075] The purpose of the bend 60 is to pierce the half-cover 57 (i.e., the piercing guide groove 58) with less effort. After the tip of the piercing body 40 has pierced the half-cover 57, the external force applied to expand the opening of the half-cover 57 will be less than that required for piercing. Therefore, after the piercing body 40 has pierced the half-cover 57, the stop bar 53 can return to a straight shape. Thus, the starting point of the bend 60 is set when the stop block 41 is about to enter the bend 60, and the tip of the piercing body 40 just reaches the piercing guide groove 58; the ending point of the bend 60 is set when the stop block 41 moves out of the bend 60, and 1 / 5 to 1 / 3 of the tip of the piercing body 40 has penetrated the half-cover 57 and protruded beyond the bottom surface of the cover cylinder 51.

[0076] Based on the above description, the length of the first bend 61 is greater than the length of the second bend 62. To ensure the airtightness of the cap 10 to the first material, the half-cap 57 on the main cap 50 in this application is designed to be integrally manufactured with the cap cylinder 51, and a circular puncture guide groove 58 is pressed out around the half-cap 57 by pressing or other means. Therefore, the puncture guide groove 58 has a strength similar to or even stronger than the material of the cap cylinder 51 itself, making it difficult to perform a puncture operation using a straight line. Therefore, it is necessary to first perform a thorough and effective cut on the puncture guide groove 58 to at least partially reduce the rigidity of the puncture guide groove 58. Furthermore, it is necessary to make the reciprocating cutting operation of the puncture body 40 based on the previous cut. That is, by designing a shorter second bend 62 stroke, the secondary cut of the puncture body 40 can fall completely within the stroke range of the first bend 61 to achieve labor-saving puncture. Even if the puncture is not effective in the second bend 62 stroke, the second bend 62 is followed by a smooth transition straight stroke, and the puncture can be completed through a straight stroke that applies force more directly.

[0077] Furthermore, based on the above technical solution, the inclination of the second bend 62 can be designed to be greater than that of the first bend, thereby ensuring effective puncture.

[0078] Example 3.

[0079] The above embodiment provides a cap 10 capable of independently sealing a first material, which is assembled onto a bottle 20 containing a second material, enabling isolated and sealed packaging of the two materials. However, in use, it was found that when the piercing body 40 pierces the half-cap 57 at the bottom of the cap cylinder 51, the secondary cap 30 is rotated to detach from the main cap 50 and also from the piercing body 40 because the half-cap 57 needs to be fully opened. At this time, the front end of the piercing body 40 is also stuck in the piercing guide groove 58 of the half-cap 57. The piercing body 40 not only affects the entry of the first material into the bottle 20, but also affects the pouring out of the bottle 20 after the two materials are mixed for user use. Therefore, the piercing body 40 needs to be removed from the main cap 50 after piercing.

[0080] like Figure 6 , 7 As shown, based on the above embodiment, the sub-cover 30 in this embodiment is provided with a hook 70. The upper end of the hook 70 is fixed to the bottom 33 of the sub-cover, and the lower end is a free end. The lower end of the hook 70 is provided with a barb 71. The upper end of the piercing body 40 is provided with a hook plate 43 that matches the barb 71 of the hook 70. The hook plate 43 is fixed to the top of the piercing body 40 and has a hook hole 44 in the middle that allows the barb 71 to pass through. The hook 70 can be integrally formed with the sub-cover 30, or it can be fixed to the sub-cover 30 after the sub-cover 30 is made by means including but not limited to snaps, threads, welding, etc. The specific fixing position is: the upper end of the hook 70 is fixedly connected to the middle position of the inner wall of the bottom 33 of the sub-cover, and preferably the hook 70 is perpendicular to the bottom 33 of the sub-cover, so that the barb 71 at the front end of the hook 70 can hook onto the hook plate 43 of the piercing body 40. Furthermore, the length of the hook 70 should be greater than or equal to the height of the inner cover 31 in the sub-cover 30, so that after the puncture body 40 rotates and separates from the sub-cover 30, the puncture body 40 is still loosely connected to the sub-cover 30, and when the sub-cover 30 is removed from the cover body 10, the puncture body 40 is also removed together.

[0081] The function of the hook plate is to provide hook holes 44 at the upper end of the puncture body 40 so that the hooks 70 on the sub-cover 30 can be loosely connected to the puncture body 40. Therefore, the hook plate can be a frame structure or a flat plate structure, etc.

[0082] like Figure 7As shown, the hook 70 is a spiral made of elastic material, and the barb 71 includes a hook body and barbs. The hook body is made of rigid material, and the barbs are made of a material with a deformation capacity greater than that of the hook 70 and less than that of the hook body. When the piercing body 40 is screwed into the inner cover 31 of the sub-cover 30, and the tip of the piercing body 40 is about to reach the bottom of the inner cover 31, the barb 71 will pass through the hook hole 44 on the hook plate, and further hang the piercing body 40 on the sub-cover 30 through the barbs. Because the hook 70 and the hook plate are loosely connected, the hook plate restricts the hook 70 from reversing out of the hook hole 44, but when the sub-cover 30 and the hook 70 rotate, this rotation does not interfere with the hook plate and the piercing body 40, and the piercing body 40 can rotate freely relative to the sub-cover 30.

[0083] The hook plate is a flat disc, and a hook bag is provided at the hook hole 44. The hook bag and the hook plate 43 form a sealing body to isolate the hook from the inner cavity of the puncture body 40.

[0084] Example 4.

[0085] Based on the above embodiments, the secondary cover 30 in this embodiment is provided with a pull ring 80, which is disposed on the outer side of the secondary cover wall 32. The pull ring 80 includes a wristband 81 and a bar ring 82. The wristband 81 is made of an elastic material with a deformation range of less than 150%, and the bar ring 82 is made of a rigid material. The wristband 81 is elliptical and can accommodate 1-2 fingers of the user, and the bar ring 82 is circular with a diameter of 8-10 mm. In the above embodiments, when it is necessary to release the first material from the capping body 10 and fuse it with the second material, the driving force is generated by the torsion of the secondary cover 30 to drive the piercing body 40 downward and open the half cover 57 on the cap cylinder 51 to release the first material. As mentioned earlier, due to requirements for airtightness, safety, and stability, the materials of each component of the cap 10 are relatively thicker than those of the bottle body 20. That is, for the secondary cap 30 to twist and drive the piercing body 40 to open the half-cap 57 to release the first material, a relatively large gripping force needs to be applied to the secondary cap 30. When the secondary cap 30, main cap 50, and bottle body 20 adopt conventional structures, the anti-slip textures on the outer walls of the secondary cap 30 and main cap 50 make it difficult to achieve the aforementioned large gripping force. Therefore, it is likely necessary to use external auxiliary clamping devices or similar tools to achieve a larger torsional gripping force. In real life, the purpose of the two independently packaged materials described in this application is to facilitate carrying, use, and operation. If additional auxiliary clamping devices are required during the use of this packaging container, it would contradict the purpose of this invention. Therefore, in this embodiment, two pull rings 80 are provided on the outer wall of the sub-cover 30. The function of the wrist ring 81 is reflected in two aspects: first, when twisting the sub-cover 30, the finger can be put on the wrist ring 81, which restricts the sub-cover 30 to the finger and prevents the sub-cover 30 from sliding during twisting, thus preventing the piercing body 40 from being pushed down to open the half-cover 57; second, the wrist ring 81 can also serve as a handle for the entire packaging container, making it convenient to carry. The function of the rod ring 82 is that the rod ring 82 is made of a rigid material, but the aperture is small, which can only accommodate relatively thin rod-shaped objects such as chopsticks. The reason for the small aperture is that the rod ring 82 is set in the same position as the wrist ring 81, and the smaller rod ring 82 does not affect the use of the wrist ring 81. On the other hand, the packaging container is generally used to hold food, and rod-shaped objects such as chopsticks are relatively easy to obtain when using the food. It is fundamentally different from the above-mentioned special auxiliary clamping device.

[0086] Example 5.

[0087] like Figure 8As shown, based on the above embodiments, this embodiment describes a packaging container with a well-sealed inner piercing cap. The bottleneck 22 is a tall, narrow cylinder. When the main cap 50 is assembled with the packaging container, the bottom end of the bottleneck 22 is flush with the bottom of the cap cylinder 51 of the main cap 50, or the bottom end of the bottleneck 22 extends beyond the bottom of the cap cylinder 51. In this embodiment, the thickness of the cap rim 52 of the main cap 50 and the bottleneck of the bottle body 20 are similar to facilitate a more effective grip, so as to cooperate with the twisting of the secondary cap 30 to drive the piercing body 40 to pierce the half cap 57.

[0088] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solutions of the present invention and not to limit it. Although the present invention has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications and substitutions should be covered within the scope of the claims of the present invention.
