Description

Technical Field

[0001] The invention relates to the technical field of beverages, in particular to an antiseptic bottle cap for storing concentrated nutrient sauce. Background Art

[0002] A kind of bottle cap beverage is popular in the market now. The freeze-dried powder is stored in a bottle cap container. When it needs to be drunk, the container is screwed into a mineral water bottle and the freeze-dried powder is squeezed into the mineral water. This bottle cap beverage is very convenient to carry.

[0003] However, the common packaged fruit juices in the market are not only freeze-dried powder, but also concentrated liquid and jam. The juice brewed from concentrated liquid and jam tastes better, while the bottled drinks on the market are all freeze-dried powder, and there are few bottled drinks in the form of concentrated liquid and sauce. This is because freeze-dried powder has a very low moisture content and is easier to store, and its poor fluidity requires lower sealing requirements for containers. Jam is extremely prone to rot and deterioration. If jam wants to achieve the same shelf life, it needs better sealing treatment to prevent oxygen from entering and oxidizing. In addition, the sauce will stick to the inner wall of the container and is difficult to enter the mineral water bottle. The sealing and fluidity problems are difficult to solve at the same time. Summary of the invention

[0004] In order to solve the above-mentioned prior art problems, the present invention provides an antiseptic bottle cap for storing concentrated nutritional sauce, comprising a container body for containing a beverage medium;

[0005] A piston is slidably connected to the inner wall of the container body and is used to squeeze the beverage brewing medium in the container body;

[0006] A communication pipe runs through both ends of the container body, and one section of the communication pipe is connected to the container body;

[0007] Wherein, the piston is connected to the lower end of the container body with a first sealing film;

[0008] Wherein, the piston has a communicating hole, and the communicating pipe passes through the communicating hole; and the piston is connected to the communicating pipe through a second sealing film to close the communicating hole;

[0009] The diameter of the communication hole is larger than the diameter of the communication pipe, and the gap between the two forms a sauce outlet;

[0010] Wherein, the lower end surface of the piston has a connecting structure for connecting to the bottle mouth thread.

[0011] Furthermore, the communicating pipe has an annular boss, and the side wall of the annular boss is fitted with the side wall of the communicating hole to form a primary seal, and the primary seal prevents the jam from flowing out.

[0012] Furthermore, the second sealing film has an inflated area, the inflated area bulges toward the non-connecting surface of the second sealing film; the inflated area covers the gap of the primary seal;

[0013] The primary seal allows gas to pass through.

[0014] Further, it also includes a locking mechanism;

[0015] The locking mechanism includes a locking portion A arranged on the communicating hole and a locking portion B arranged on the communicating pipe. The locking portion A and the locking portion B cooperate to keep the upper end surface of the piston in contact with the inner top surface of the container body, thereby ensuring the sealing effect on the water bottle.

[0016] Further, the locking portion A is an internal connecting thread provided on the connecting hole, and the locking portion B is an external connecting thread provided on the connecting pipe;

[0017] Wherein, a connecting groove is further provided in the locking mechanism, and the connecting groove cuts off the inner connecting thread and / or the outer connecting thread along the axial direction of the connecting pipe.

[0018] Further, the locking portion A is an elastic protrusion A provided on the communicating hole, and the locking portion B is an elastic protrusion B provided on the communicating pipe;

[0019] The elastic protrusion A and the elastic protrusion B form an inclined plane to match each other, so as to convert the elastic force in the horizontal direction into the elastic force in the vertical direction.

[0020] Furthermore, a limiting portion A is provided on the inner top surface of the container body, and a limiting portion B is provided on the top surface of the piston. The limiting portion B is coupled with the limiting portion A to prevent the piston and the container body from rotating relative to each other.

[0021] Furthermore, a sealing ring is provided on the inner top surface of the container body or the upper end surface of the piston, and when the upper end surface of the piston abuts against the inner top surface of the container body, the upper end surface of the piston squeezes the sealing ring.

[0022] Furthermore, a valve structure is provided inside the communicating pipe.

[0023] Furthermore, the outer wall surface of the container body is connected to a cover body, and the cover body is provided with an abutment protrusion for abutting the valve structure.

[0024] The beneficial effect of the present invention is that by using the container of the present application, not only can the sauce in the sauce container body be completely pushed into the water bottle through the piston, but also the layout of the sauce outlet and the drinking port of the container of the present application can completely seal the sauce in the container body, effectively extending the shelf life of the sauce inside and preventing the sauce from spoiling. Thus, jam with higher nutritional content and better taste can be used as the drinking medium of the bottle cap beverage. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Example 1

[0035] Reference Figure 1 - Figure 7 .

[0036] An antiseptic bottle cap for storing concentrated nutritional sauce, comprising a container body 1 for containing a beverage preparation medium;

[0037] A piston 2 is slidably connected to the inner wall of the container body 1 and is used to squeeze the beverage brewing medium in the container body 1;

[0038] A communication pipe 3 passes through both ends of the container body 1, and one section of the communication pipe 3 is connected to the container body 1;

[0039] Wherein, the piston 2 is connected to the lower end of the container body 1 through a first sealing film 4;

[0040] The piston 2 has a communication hole 23, and the communication pipe 3 passes through the communication hole 23; and the piston 2 and the communication pipe 3 are connected through a second sealing film 5 to close the communication hole 23;

[0041] The diameter of the communication hole 23 is larger than the diameter of the communication pipe, and the gap between the two forms a sauce outlet;

[0042] The lower end surface of the piston 2 has a connecting structure 21 for connecting to the thread of the bottle mouth 92 .

[0043] The medium of the granule is preferably a sauce or a concentrated stock solution, and a freeze-dried powder can also be used. The application itself is mainly for sauces, which can be not only jams but also viscous liquids such as chocolate sauce and milkshakes. Jam, as a medium for mainstream beverages, has higher nutritional content and better taste. The main problem with the difficulty of using sauces or stock solutions as the medium for beverages with bottle caps is that a sealed space is formed after the container is connected to the water bottle 91, and it is difficult to push the medium for beverages into the water bottle 91. If you want to push the sauce out of the container, you usually use a piston 2 structure, and pushing by the piston 2 will increase the pressure in the water bottle 91. Therefore, the piston 2 must have an exhaust function when pushing, and the exhaust function means that the container has an exhaust hole, and the sealing performance of the container with an exhaust hole will be reduced, and the sauce cannot be preserved and aseptically treated, especially when the medium for beverages is jam, aseptic treatment is more important, and bacteria are very easy to breed in the jam. Jam will be exposed to a small amount of bacteria when it is slightly exposed to the air. The jam is extremely suitable for bacteria to survive, and the bacteria will multiply in large numbers, causing the jam to rot and deteriorate in a short time. The container with the sealing structure of the present application does not need to have an exhaust hole, so that the beverage medium is completely sealed inside the container, which can better perform aseptic processing during the production process and ensure that bacteria have difficulty in contacting the beverage medium in the finished product.

[0044] In the present application, the direction close to the bottle mouth 92 is downward, and the opposite direction is upward. In the same part, the direction close to the downward is the bottom surface, and the direction close to the upward is the top surface.

[0045] In order to solve the problem that the sauce is difficult to flow out and it is difficult to ensure the sealing effect, the present application provides an antiseptic bottle cap for storing concentrated nutritious sauce, including a container body 1 filled with a drink medium, a piston 2 is arranged in the container body 1, and the drink medium is located between the piston 2 and the top surface inside the container body 1. The piston 2 is provided with a connecting hole 23 and a connecting structure 21, and the present application also includes a connecting pipe 3, which is used as an exhaust structure and a drinking port. Of course, the user can also directly unscrew the present application and drink water directly from the bottle mouth 92. The connecting pipe 3 can be directly integrally formed with the container body 1, the top of the container body 1 is completely connected to the circumferential wall of the connecting pipe 3 to ensure sealing, and the connecting pipe 3 completely passes through the container body 1 and is inserted into the connecting hole 23. Finally, the piston 2 is connected to the container body 1 through the first sealing film 4, and the piston 2 is connected to the connecting pipe 3 through the second sealing film 5. When the first sealing film 4 and the second sealing film 5 are not damaged, the beverage brewing medium is completely sealed. When the first sealing film 4 and the second sealing film 5 are damaged, the piston 2 and the container body 1 can slide to squeeze the beverage brewing medium. After the second sealing film 5 is damaged, the beverage brewing medium can enter the water bottle 91 through the connecting hole 23. At the same time, when the beverage brewing medium is squeezed into the water bottle 91, the gas in the water bottle 91 is discharged through the connecting pipe 3 (most of the mineral water bottles 91 on the market currently do not completely fill the water bottles 91, so there is no need to worry about water overflowing when squeezing the beverage brewing medium), thereby reducing the pressure in the water bottle 91.

[0046] In this embodiment, the sauce outlet is formed between the connecting hole 23 and the connecting pipe 3. The connecting pipe 3 can discharge the gas in the water bottle 91. At the same time, the sauce will not be oxidized by contacting the air, ensuring that the jam in the container body 1 can be stored for a long time.

[0047] It is worth mentioning that compared with the freeze-dried powder package, the jam package needs to be sealed after nitrogen filling to avoid the jam from deteriorating and oxidizing. Therefore, the requirements for packaging of the jam package are higher, and the sealing film and the connection strength of the sealing film will be higher. Correspondingly, the sealing film of the jam package will be more difficult to open than the sealing film of the freeze-dried powder package. Bottled beverages in the form of freeze-dried powder on the market can destroy the sealing film of the device by squeezing a pump head above the device, and then the freeze-dried powder falls into the water bottle 91, that is, the sealing film is directly punctured by the force of a vertical sealing film. For existing products, this way of opening the sealing film is already very laborious. And the sealing film must not be completely separated from the device and fall into the water bottle 91, and the sealing film needs to open a larger range in the direction of the water bottle 91 to allow the freeze-dried powder to fall naturally, resulting in a large amount of water droplets sticking to the sealing film, and only a small part of the sealing film is connected to the device, which causes the sealing film to form a cantilever structure, which is very easy to shake. After unscrewing the bottle cap, the water droplets on the sealing film are very easy to shake off, and the user must tear off the sealing film with water droplets.

[0048] In the present application, the process of connecting the connecting structure 21 with the bottle mouth 92 requires screwing the container body 1. Before the piston 2 abuts against the bottle mouth 92, screwing is very easy, and only a small force can be transmitted to the first sealing film 4 and the second sealing film 5 through the piston 2. After the piston 2 abuts against the bottle mouth 92, the piston 2 is basically fixedly connected to the water bottle 91. At this time, if the screwing is continued, most of the force can be transmitted to the first sealing film 4 and the second sealing film 5, thereby destroying the sealing film. The strength of the adhesive of the sealing film is weaker than the structural strength of the sealing film itself, and it is easier for people to apply force by screwing than by pressing the pump head (pressing with the thumb, not the whole palm). Therefore, the structure of the present application can destroy the sealing film more labor-savingly. When there is a node from labor-intensive to labor-saving during the screwing process, it means that the sealing film is destroyed, and then the container body 1 can be directly pushed toward the bottle mouth 92 to quickly squeeze out the beverage medium.

[0049] Moreover, after the structural sealing film of the present application is destroyed, it is not necessary to form a large outlet to allow the brewing medium to fall naturally like in the prior art. The present application only needs to form a smaller outlet, and then the brewing medium can be squeezed out by the squeezing of the piston 2, so that the sealing film will not be too protruding and form a cantilever structure to shake off water droplets.

[0050] Another point is that the present application can accommodate more drink brewing media, and the prior art can also accommodate a lot of drink brewing media, and it only needs to make the container larger, but this will make the device itself appear very abrupt on the water bottle 91, unless the device is unscrewed and replaced with the original bottle cap after the brewing is completed. In the process of squeezing the drink brewing medium, the volume of the device of the present application is constantly shrinking, and the top of the container body 1 gradually approaches the bottle mouth 92, so the container body 1 of the present application can be made longer, and when the device is connected to the bottle mouth 92, it will also be very abrupt, but in the process of squeezing the drink brewing medium, the container body 1 gradually approaches the bottle mouth 92, reducing the protruding height (the connecting pipe 3 and the container body 1 move synchronously), that is, the device of the present application is not abrupt during the drinking process.

[0051] During the production process, the piston 2 and the connecting structure 21 are injection molded, the container body 1 and the connecting pipe 3 are injection molded, the piston 2 is connected to the first sealing film 4 and the second sealing film 5 in advance, and then the container body 1 is filled with the beverage brewing medium, and nitrogen is filled into the container body 1. Finally, the piston 2 and the container body 1 are buckled together to encapsulate the sealing film.

[0052] Example 2

[0053] Reference Figure 1 - Figure 6 .

[0054] The communication pipe 3 has an annular boss 31 , and the side wall of the annular boss 31 is in contact with the side wall of the communication hole 23 to form a primary seal, which prevents the jam from flowing out.

[0055] The second sealing film 5 connects the piston 2 and the connecting tube on one side facing the inside of the container body 1. The first sealing film 4 and the second sealing film 5 are both connected by bonding. For bonding, there will be the problem of glue erosion, especially for some acidic jams, such as orange juice jam, lemon juice jam, etc. Therefore, the jam should be prevented from contacting with the sealing film (the first sealing film 4 and the second sealing film 5). The first sealing film 4 has an outer wall surface of the piston 2 and an inner wall surface of the container body 1 to achieve sealing. In this application, it is assumed that the clearance between the piston 2 and the container body 1 can prevent the jam from flowing in. For the second seal, a separate sealing structure needs to be set.

[0056] An annular boss 31 may be provided on the periphery of the communicating pipe 3 , and the side wall surface of the annular boss 31 cooperates with the communicating hole 23 to form a sealing structure similar to that of the piston 2 , thereby achieving primary sealing.

[0057] Example 3

[0058] Reference Figure 1 - Figure 6 .

[0059] The second sealing film 5 has an inflated area 51, and the inflated area 51 is raised toward the non-connected surface of the second sealing film 5; the inflated area 51 covers the gap of the primary seal;

[0060] The primary seal allows gas to pass through.

[0061] For many nitrogen-filled canned foods, the sealing film of the bottle mouth 92 will bulge and expand, and the bag of the bagged food will expand, and words such as "leakage and inedible" will be marked on the packaging.

[0062] The product of this type in the present application is very small in size, and the second sealing film 5 is an annular structure with an outer diameter smaller than the bottle mouth 92 of the water bottle 91, and the second sealing film 5 is pasted in a plane (the end face of the piston 2 and the end face of the annular boss 31). If the second sealing film 5 is still a plane structure, it is almost impossible for the second sealing film 5 to have a significant bulge. In this embodiment, the second sealing film 5 has an inflation area 51, and the inflation area 51 itself bulges toward the non-connecting surface of the second sealing film 5. The so-called non-connecting surface refers to the side of the second sealing film 5 that is not coated with glue. The primary seal allows gas to pass through. For the sealing structure of the abutment type, it is difficult to maintain airtightness. It only needs to control the matching accuracy to prevent jam from passing through and allow gas to pass through. The inflation area 51 covers the gap of the primary seal, that is, the gas in the container body 1 is connected to the air in the inflation area 51 at this time, so whether the inflation area 51 is bulged can be used as the basis for whether the container body 1 is leaking, thereby confirming the sealing of the food to prevent food oxidation and deterioration.

[0063] At the same time, the second sealing film 5 is located inside the connecting structure 21 , and the protruding connecting structure 21 can effectively prevent the second sealing film 5 from being punctured.

[0064] Example 4

[0065] Reference Figure 1 - Figure 6 .

[0066] The concentrated jam storage device of this embodiment further includes a locking mechanism 6;

[0067] The locking mechanism 6 includes a locking portion A61 arranged on the connecting hole 23 and a locking portion B62 arranged on the connecting pipe 3. The locking portion A61 and the locking portion B62 cooperate to keep the upper end surface of the piston 2 in contact with the inner top surface of the container body 1, thereby ensuring the sealing effect on the water bottle 91.

[0068] After the user pushes the jam into the water bottle 91, the user needs to shake the water bottle 91 to complete the mixing. Then the liquid will flow through the connecting hole 23 to impact the inner top surface of the container body 1 (at this time, the inner top surface of the container body 1 has been in contact with the end surface of the piston 2). The top of the container body 1 gradually moves away from the piston 2. At this time, the second sealing film 5 and the first sealing film 4 have already broken, and the piston 2 and the container body 1 can be completely separated. After the complete separation, not only will the liquid spill out, but the jam adhered to the end surface of the piston 2 will also be difficult to handle. This is obviously something that the user does not want to happen. In addition, at this time, the device has acted as a bottle cap to seal the water bottle 91. The water bottle 91 is very easy to deform, and the water bottle 91 will inevitably have some collisions and extrusions. The fluidity of the liquid in the water bottle 91 is much greater than that of the jam. Therefore, the piston 2 structure is difficult to ensure the sealing of the liquid in the water bottle 91.

[0069] In this embodiment, a locking mechanism 6 is added so that after the jam is pushed out, the inner top surface of the container body 1 and the end surface of the piston 2 always keep in contact, and the sealing effect on the liquid is increased through the cooperation of the two end surfaces.

[0070] In this embodiment, two specific locking mechanisms 6 are provided.

[0071] 1. Reference Figure 6 , the locking part A61 is: an internal connecting thread, which is arranged in the connecting hole 23; the locking part B62 is: an external connecting thread, which is arranged in the connecting pipe 3. More specifically, the starting point of the external connecting thread is at the intersection of the connecting pipe 3 and the inner top surface of the container body 1, and extends toward the piston 2. The external connecting thread only needs to be set to 1-3 turns. This is because when the external connecting thread and the internal connecting thread are matched, the inner top surface of the container body 1 and the end surface of the piston 2 must be brought close by rotating the container body 1. The thread is a labor-saving non-distance working method, which is much more troublesome than directly pressing the container body 1. Therefore, the thread matching stroke should be shortened as much as possible, so that the user can more conveniently push out the remaining jam. Further, the internal connecting thread and the thread rotation direction of the connecting structure 21 are the same, which means that the locking mechanism 6 can simultaneously drive the connecting structure 21 and the bottle mouth 92 to tighten the thread during the screwing process, thereby avoiding the problem that the connecting structure 21 and the bottle mouth 92 may not be tightly connected at the beginning, resulting in the subsequent shaking of the liquid.

[0072] The inner connecting thread and / or the outer connecting thread are provided with a connecting groove 63, and the connecting groove 63 cuts off the thread along the axial direction of the connecting pipe 3 to avoid blocking the flow of jam when the inner connecting thread and the outer connecting thread cooperate. The jam can flow out through the connecting groove 63.

[0073] 2. Reference Figure 4 and 5 , the locking portion A61 is an elastic protrusion A provided on the communicating hole 23, and the locking portion B62 is an elastic protrusion B provided on the communicating pipe 3;

[0074] The elastic protrusion A and the elastic protrusion B form an inclined plane to convert the elastic force in the horizontal direction into the elastic force in the vertical direction. It is sufficient for one of the elastic protrusion A and the elastic protrusion B to be elastic. For example, the elastic protrusion A provided in the connecting hole 23 is elastic, but the elastic protrusion B does not need to be elastic. The elastic protrusion A may be a semicircular arc in cross section, with both ends of the semicircular arc connected to the side wall of the connecting hole 23, and the middle part is elastic, while the elastic protrusion B may be a semicircular structure in cross section (or the same structure as the elastic protrusion A). With the relative movement between the container body 1 and the piston 2, the elastic protrusion A and the elastic protrusion B abut against each other, and the initial abutting position is located on one side of the horizontal diameter of the elastic protrusion A. At this time, the elastic force of the elastic protrusion A on the elastic protrusion B will make the inner top surface of the container body 1 and the end surface of the piston 2 move away from each other. The elastic protrusion A continues to move and deform until the center of the elastic protrusion B enters one side of the horizontal diameter of the elastic protrusion A. At this time, the elastic force will make the inner top surface of the container body 1 and the end surface of the piston 2 approach each other. When the elastic force reversal is completed, the inner top surface of the container body 1 and the end surface of the piston 2 should be in abutment, so it is necessary to pay attention to controlling the height position of the elastic protrusion A and the elastic protrusion B.

[0075] Further, based on the locking structure in the form of an elastic protrusion, a limiting portion A11 is provided on the inner top surface of the container body 1, and a limiting portion B22 is provided on the top surface of the piston 2. The limiting portion B22 is coupled with the limiting portion A11 to prevent the piston 2 from rotating relative to the container body 1. Specifically, the limiting portion B22 can be set as a protrusion, and the limiting portion A11 can be set as a groove. When the limiting portion B22 enters the limiting portion A11, the two will prevent the piston 2 and the container body 1 from rotating relative to each other, so that rotating the container body 1 can drive the piston 2 to rotate, that is, loosening or tightening the connection between the connecting structure 21 and the bottle mouth 92. The user can easily unscrew the connecting structure 21 of the bottle mouth 92 and use the bottle mouth 92 as a drinking port.

[0076] Example 5

[0077] The piston 2 and the container body 1 do not have to be set to a cylindrical shape, but can also be set to other polygonal structures, such as a hexagonal prism. If set to a prism shape, the piston 2 and the container body 1 cannot rotate relative to each other, and the user can easily unscrew the connecting structure 21 of the bottle mouth 92 and use the bottle mouth 92 as a drinking port.

[0078] Example 6

[0079] A sealing ring 7 is provided on the inner top surface of the container body 1 or the upper end surface of the piston 2 . When the upper end surface of the piston 2 abuts against the inner top surface of the container body 1 , the upper end surface of the piston 2 squeezes the sealing ring 7 .

[0080] Example 7

[0081] The communicating pipe 3 is provided with a valve structure 32 inside;

[0082] The outer wall surface of the container body 1 is connected to a cover body 8 , and the cover body 8 is provided with an abutting protrusion for abutting against the valve structure 32 .

[0083] The valve structure 32 is a common structure in some sports drinks and sports water bottles (especially road sports), which can prevent liquid from dripping. At the same time, when the user squeezes the bottle, the liquid can break through the valve structure 32 and flow out, which is convenient for the user to drink water with one hand. The outer wall surface of the container body 1 is connected to the cover body 8, and the cover body 8 is provided with an abutting protrusion for abutting the valve structure 32 to prevent the liquid from flowing out when the user does not want to drink water. At the same time, the cover body 8 also plays a role in dust and dirt prevention.

[0084] The device of this embodiment is sports-oriented and can replace pure jam with sports supplements such as energy gels.
