Background

With the improvement of quality of life, it is becoming common knowledge of various industries that the liquid container should have the properties of being convenient to fold and recycle. Both small bottle containers and large bottle drinking vessels are increasingly being designed with the body of the bottle in a compressible configuration.

For example: patent document CN201520313034.6 discloses "a sports plastic bottle capable of being compressed and bent", and its background art correspondingly mentions "people have increased sales of containers for various liquids made of plastic, and after use, the plastic bottle is discarded. These empty bottles, which were used to contain liquids, tend to occupy a large volume. And, its figure 1 has also expressed the body compressible directly perceivedly, thus is convenient for compress and does benefit to and dwindles the volume, and then is convenient for retrieve.

For another example, the patent document CN200980112758.1 discloses a bottle for water dispenser, which has a compressible body, and solves the main technical problem of replacing drinking water in a barrel by compressing the body, so as to prevent air from entering the inside of the body of the water dispenser, thereby preventing the water dispenser from being polluted by air during use. Simultaneously, it has had concurrently the advantage that the body is also convenient for retrieve after being compressed.

However, current collapsible containers are relatively difficult to collapse, for example, when the body is collapsed, the body may be undesirably deformed, which may result in a reduced compressibility of the body (defined as the maximum degree of compressibility), or when the body is partially broken, which may result in a reduced compressibility of the body.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.

Fig. 1 to 3 show a liquid container according to a preferred embodiment of the present invention, which is an integrally formed structure. As shown in fig. 2, when the liquid container is placed horizontally, the liquid container includes, from bottom to top, a barrel bottom, a barrel body 1, a shoulder 2, and a neck 3, which are connected in sequence. The side wall of the barrel body 1 is divided into a plurality of barrel body side walls positioned on different space surfaces by the barrel body 1 along the circumferential direction of the axis of the barrel body 1; the barrel body 1 is provided with a plurality of folds 11 sequentially arranged along the axial direction of the barrel body 1 on each barrel body side wall of the barrel body 1, each fold 11 comprises a wave crest 111 and fold side walls 112 respectively arranged at two sides of the wave crest 111, and a wave trough 113 is formed at the joint of the fold side walls 112 between two adjacent folds 11 on the same barrel body side wall; the wave crests 111 between two adjacent barrel side walls are arranged along the axial direction of the barrel 1 in a staggered manner, and the wave troughs 113 between two adjacent barrel side walls are arranged along the axial direction of the barrel 1 in a staggered manner.

In order to interpret and analyze the effect of the present liquid container in more detail, it is necessary to incorporate patent documents of the prior art. Taking a bottle for a water dispenser disclosed in patent application No. CN200980112758.1 as an example, in an original state, the minimum inner diameter and the maximum outer diameter of the corrugated portion are fixed values, and in the process of compressing the corrugated portion, the minimum inner diameter of the corrugated portion will be continuously reduced, while the maximum outer diameter of the corrugated portion will be continuously increased, so that the compression process of the bottle body portion is not an ideal process in which the bottle body portion is gradually linearly compressed; and then lead to its body to take place serious unexpected deformation (taking place serious deformity promptly) for the compressible degree of body portion suddenly reduces, has led to this a bottle for drinking machine promptly and can't take out (a large amount of grooves of body portion remain the water) the water source in the final water yield of in-service use. And, with the gradual enhancement of unexpected deformation, when the bottle body loses the performance of easy compression, the water outlet speed is reduced, even the water needs to be replaced by air, and finally, the problem that the water body is polluted by the air still exists.

In the liquid container of the present application, since the side wall of the barrel 1 is divided into a plurality of barrel side walls located on different spatial planes by the barrel 1 along the circumferential direction of the axis of the barrel 1, based on the aforementioned condition, the following structure can be set: the wave crests 111 between two adjacent barrel side walls are arranged along the axial direction of the barrel 1 in a staggered manner, and the wave troughs 113 between two adjacent barrel side walls are arranged along the axial direction of the barrel 1 in a staggered manner. Thus, when the barrel body 1 is folded, the mutual extrusion degree between the wave crests 111 of the adjacent barrel body side walls is small, and even the mutual extrusion is avoided; the mutually extruded degree between the wave troughs 113 of the adjacent barrel side walls is small, even the mutually extruded degree is not generated; the mutual extrusion degree between the adjacent barrel side walls is greatly reduced, so that the change rate of the circumference of the inscribed circumference and the circumscribed circle of the barrel 1 is lower, the barrel 1 of the liquid container can be linearly compressed in the actual use process, namely, the deformation amount is less, the compressible cruising ability of the barrel 1 is sufficient, and finally, each fold 11 of the barrel 1 is almost completely compressed, so that the problem of the reduction of the compressibility of the barrel 1 caused by the deformation change of the compression process of the barrel 1 is solved, and the phenomenon of local fracture caused by the excessive deformation of the barrel 1 is avoided.

Obviously, the liquid container is suitable for barreled coca-cola, soy sauce bottle, peanut oil bottle, bottled coca-cola, etc. It can be understood that the liquid container is applied to different liquid containers, the problem that waste products occupy large space (for example, a pop can does not need to step on one foot manually) can be solved, and the phenomenon of local breakage of the barrel 1 can not occur in the process of extruding the barrel 1, so that unnecessary cleaning work is avoided. In addition, because the deformation amount of the barrel body 1 in the compression process is smaller, the barrel body 1 can be greatly compressed (namely, the compression degree of the barrel body 1 is higher), and the barrel is beneficial to carrying waste products by owners.

In addition, the liquid container is also very suitable for drinking water bottles, particularly barreled drinking water buckets, and can be almost completely compressed due to high compressibility of the liquid container, so that the problem that a small amount of drinking water is finally remained in the barrel body 1 can be solved. Moreover, the liquid container can also prevent the phenomenon that the groove and then part of water body are intercepted because the barrel body 1 is deformed. In addition, the compression process of the barrel body 1 of the liquid container can not cause excessive stress concentration, so that the barrel body 1 can be effectively prevented from being broken, the barreled drinking water is generally used for a long time, and the phenomenon of breakage and air leakage of the barreled drinking water barrel (namely, the phenomenon that air enters the barrel body 1) is prevented. It is also necessary to supplement that, because of the higher compressibility, the water volume remained at last is less, and the water body is replaced by the reduced volume, so that the faster water outlet speed can be still maintained; in fact, during the whole water outlet process of the barreled drinking water barrel, little or no air leaks into the barrel body 1, so that the water body can be more effectively prevented from being polluted by the air.

As a further preferred embodiment, taking one of the barrel side walls of the barrel 1 as the reference wall a and the other two barrel side walls adjacent to the reference wall a as the adjacent wall B and the adjacent wall C, respectively, the folds 11 on each barrel side wall are arranged as follows: the wave crests 111 of the pleats 11 on the reference wall A and the wave crests 111 of the pleats 11 on the adjacent walls B and C are sequentially staggered along the axial direction of the barrel 1, the wave troughs 113 of the pleats 11 on the reference wall A and the wave troughs 113 of the pleats 11 on the adjacent walls B and C are sequentially staggered along the axial direction of the barrel 1, so that the wave crests 111 of the pleats 11 forming the reference wall A correspond to the wave troughs 113 of the adjacent walls B and C, and the wave troughs 113 of the pleats 11 forming the reference wall A correspond to the wave crests 111 of the adjacent walls B and C. The sequential staggered mode is more beneficial to sequential folding layer by layer; if the horizontal plane at the wave crest 111 and the wave trough 113 of any layer of the barrel body 1 is cut into a horizontal cross section, the outer contour perimeter of the cross section is a fixed value; that is, the levels of the various layers of the barrel 1 are of equal circumference (e.g., FIGS. 9 and 10 are cross-sectional views of the barrel 1 taken at different peaks 111 and valleys 113 of the same barrel sidewall, with a first circumference 91 equal to the total length of the first, second, third, fourth, fifth and sixth sides 91a, 91b, 91c, 91d, 91e and 91f in a first horizontal plane, as shown in FIG. 9, and a second circumference 92 equal to the total length of the seventh, eighth, ninth, tenth and twelfth sides 92a, 92d, 92e and 92f in a second horizontal plane, as shown in FIG. 10; thus the first circumference 91 is equal to the second circumference 92); therefore, the folding process of the barrel body 1 is more regular and closer to linear folding; i.e. to further reduce the amount of malformation that occurs during folding of the bowl 1. In other words, when the barrel 1 is folded, the degree of mutual pressing between the folded side wall 112 of the reference wall a and the folded side walls 112 of the reference walls B and C is further and greatly reduced, so that the change rate of the circumferences of the inscribed circle and the circumscribed circle of the barrel 1 is low, and thus, in the actual use process of the liquid container, the barrel 1 is kept in linear compression, that is, the deformation amount is less, the compressible endurance capacity of the barrel 1 is sufficient, and finally, each fold 11 of the barrel 1 is almost completely compressed, so that the problem of reduced compressibility of the barrel 1 caused by abnormal change in the compression process of the barrel 1 is solved, and the phenomenon of local rupture caused by excessive deformation of the barrel 1 is avoided.

In a further preferred embodiment, the adjacent walls B and the adjacent walls C corresponding to the same valleys 113 on the reference wall a have peaks 111 of the corrugations 11 on the same horizontal plane, and the adjacent walls B and the adjacent walls C corresponding to the same peaks 111 on the reference wall a have valleys 113 on the same horizontal plane. Thus, the folds 11 on the barrel 1 are uniformly distributed, so that the folding conditions of the adjacent walls B and C are more similar, and the compressibility of the barrel 1 is further improved.

As a further preferred embodiment, the peaks 111 of the corrugations 11 on the reference wall a are close to one end of the adjacent wall B, and are respectively connected with one ends of the peaks 111 of two corrugations 11 on the adjacent wall B, which are staggered with the adjacent wall B; the wave crest 111 of the corrugation 11 on the reference wall a is close to one end of the adjacent wall C, and is respectively connected with one end of the wave crest 111 of two corrugation 11 staggered with the adjacent wall C. Thus, a large-area surface wall (i.e., a stress concentration surface formed by accumulation of stress concentration points) which hinders compression of the barrel 1 does not exist at the boundary of the adjacent barrel side walls, that is, the compressibility of the barrel 1 is further improved. In other words, the peaks 111 and valleys 113 of the corrugations 11 are made to extend from one horizontal edge of the side wall of the tub body to the other opposite horizontal edge of the side wall of the tub body in the horizontal direction, so as to avoid the side wall of the tub body 1 from having high strength portions that hinder the compression of the tub body 1, i.e., to further improve the compressibility of the tub body 1.

The barrel 1 may have a quadrangular prism structure or an octagonal prism structure, or may have a polygonal prism structure or a polygonal pyramid structure with any even number of sides (here, it should be noted that, after the barrel 1 is horizontally cut, the outer contour of the cross section of the barrel 1 may be a polygonal prism structure). Alternatively, a polygonal structure formed by a straight edge and an arc edge may be used, that is, at least one edge of the polygonal structure is replaced by the arc edge (when converted into a surface structure, the surface is an arc surface, that is, the arc surface is provided with the folds 11).

In a finite element analysis experiment (the barrel body 1 is in a hexagonal prism structure), when the barreled drinking water barrel continuously discharges water, the change trend of the barrel body 1 changes in sequence as shown in fig. 4-6, and a corresponding experimental data graph is shown in fig. 7. Therefore, in the present embodiment, as a preferred embodiment: the barrel body 1 is of a hexagonal prism structure. Firstly, the polygonal prism structure is more advantageous for compression of the bowl 1 than a structure having curved sides. More importantly, it should be noted that in the bottle blowing process of the barreled drinking water barrel, the distances between the axis of the cylindrical barrel (the cylindrical barrel is equivalent to a polygonal column with innumerable sides) and each point on the curved surface are equal, that is, the maximum distance difference is 0, so that the bottle blowing difficulty is low. The distance between the edge between the adjacent side walls of the polygonal column and the axis of the polygonal column is defined as a first distance, the distance between the side walls of the polygonal column and the axis of the polygonal column is defined as a second distance, and the absolute value of the difference between the first distance and the second distance is gradually increased along with the decreasing of the number of the edges of the polygonal column, so that the difficulty of bottle blowing of the barreled drinking water barrel is high, and the manufacturing of the barrel 1 of the barreled drinking water (such as barreled mineral water) is not facilitated. However, since the barrel 1 in the present liquid container adopts the polygonal prism structure, and the wrinkles 11 on the different side walls of the barrel 1 can be provided in a staggered arrangement in the axial direction of the barrel 1. With this arrangement, the greater the area of the end portion of each two pleats 11 stacked (defined as the stacking area 12), the more difficult the barrel 1 is to compress. For easy understanding, referring to fig. 3, after the folded sidewall 112 is folded, the normal folded layer 5 and the doubled folded layer 4 appear at different positions, and obviously, the thickness of the doubled folded layer 4 is twice that of the normal folded layer 5; therefore, if the lamination area 12 at the multiply folded layer 4 is larger, the folding of the tub 1 is more disadvantageous. On the other hand, in the case where the circumscribed circles are equal, the larger the number of sides of the prism (the more the single variable is controlled), the larger the lamination area 12, the more difficult the barrel 1 is to be compressed. Thus, based on the preconditions: the wave crest 111 of the fold 11 on the reference wall A is close to one end of the adjacent wall B and is respectively connected with one end of the wave crest 111 of two folds 11 staggered with the adjacent wall B; the wave crest 111 of the corrugation 11 on the reference wall a is close to one end of the adjacent wall C, and is respectively connected with one end of the wave crest 111 of two corrugation 11 staggered with the adjacent wall C. And considering that the difficulty of the bottle blowing process of the hexagonal prism structure is smaller than that of the bottle blowing process of the quadrangular prism structure, and the compressibility of the hexagonal prism structure is larger than that of the octagonal prism structure, the obtained hexagonal prism barrel body 1 structure has obvious advantages. In addition, another principle needs to be added for explanation here. Referring to fig. 9 and 10, fig. 9 and 10 are cross-sections of the tub 1 at different horizontal planes, respectively; that is, under the precondition of the polygonal column structure, the peak 111 of the corrugation 11 on the reference wall a is close to one end of the adjacent wall B, and is respectively connected with one end of the peak 111 of two corrugations 11 staggered with the adjacent wall B; the wave crest 111 of the fold 11 on the reference wall A is close to one end of the adjacent wall C, and is respectively connected with one end of the wave crest 111 of two folds 11 staggered with the adjacent wall C; the first and second perimeters 91, 92 may be made equal (the detailed structure is such that: as shown in figures 9 and 10 are horizontal plane cross-sectional views of the bowl 1 taken at different peaks 111 and valleys 113 of the same bowl side wall, as shown in figure 9, in a first horizontal plane the first perimeter 91 equals the total length of the first, second, third, fourth, fifth and sixth sides 91a, 91b, 91c, 91d, 91e and 91 f; as shown in figure 10, in a second horizontal plane the second perimeter 92 equals the total length of the seventh, eighth, ninth, tenth and twelfth sides 92a, 92c, 92d, 92e and 92 f; thus the first perimeter 91 equals the second perimeter 92). Therefore, the folding process of the liquid container (or the barreled drinking water barrel) with the special hexagonal prism structure is smoother, and the compressibility of the liquid container is higher.

More importantly, finite element analysis experiments based on a barrel 1 with a hexagonal prism structure result in an experimental table as shown in fig. 7, wherein the vertical axis is volume (or volume), the horizontal axis is difference between external atmospheric pressure and gas pressure in the barrel (i.e. experimental data shows that the experimental table generates subtle negative pressure), the experimental table is mainly formulated according to an ideal gas state equation (PV nRT), wherein P is gas pressure, pa.v is gas volume, m 3.n is gas substance amount, mol, T is system temperature, k, and k, wherein in a full barrel state, the drinking water flows out from the water dispenser mainly depending on the gravity of the drinking water itself, and as the barrel 1 is compressed and the water amount is reduced, when the water amount in the barrel 1 is reduced to a first water amount 6 (see fig. 8), the experimental data shows that the air pressure in the barrel is reduced to a first volume 7 (which defines the first volume 7 as V1) (which needs to be supplemented, any soft barrel is applied to a barrel, the first water volume, i.e. a water volume is reduced to a smaller than the initial air pressure, i.e. when the water volume of the drinking water reaches a first water level, i.e. a final water dispenser, i.g. a final water level, the initial water level, a final water level, P1, a final water level is reduced, a final water level, which is reduced, a final water level, which is reduced, a final water level, i.e. a final water level, which is reduced, a final water level, which is a final water level, and a final water level, which is reduced, a final water level, which is a final water level, which is reduced, a final water level, which is a final water level, which is a final water level, a final water level is a final water level, which is a final water level, which is a final water level, which is reduced, which is a final water level, which is a final water level, which is a final water level.

Further, the pleat side walls 112 between two adjacent pleats 11 of the same barrel side wall of the barrel 1 are in a V-shaped, U-shaped, trapezoidal or rectangular structure. In the present invention, the corrugated sidewalls 112 are preferably in a V-shaped configuration, so that the edges of the barrel 1 at the junction between two adjacent barrel sidewalls are regularly arranged in a zigzag shape at equal intervals, and the zigzag configuration is very beneficial to the folding of the barrel 1, thereby further improving the compressibility of the barrel 1.

Further, the wrinkle side wall 112 between two adjacent wrinkles 11 of the same barrel side wall of the barrel 1 is in a V-shaped structure, and the wrinkle side walls 112 on two sides of the wrinkles 11 are also in a V-shaped structure, so that two adjacent wrinkles 11 of the same wall surface of the barrel 1 are adjacent to each other. With this arrangement, the large-area surface wall (i.e., the stress concentration surface formed by the accumulation of the stress concentration points) that hinders the compression of the tub 1 does not exist in the tub side wall, i.e., the compressibility of the tub 1 is further improved.

Further, the plurality of folds 11 are arranged from one end of the barrel 1 to the other end of the barrel 1 along the axial direction of the barrel 1, so that each barrel side wall of the barrel 1 can be completely folded. In this way, it is further possible to have the absence of large area walls of the side walls of the bowl 1 that impede compression of the bowl 1. Meanwhile, the compressibility of the bucket body 1 reaches a limit value, so that a part of water body trapped inside the bucket body 1 is further prevented from being taken out.

Further, the barrel 1 is a hexagonal prism structure, the diameter of the circumscribed circle range of the barrel 1 is 260mm to 270mm (wherein, the diameter of the circumscribed circle of the barrel 1 may be 261mm, 261.5mm, 262mm, 262.5mm, 263mm, 263.5mm, 264mm, 264.5mm, 265mm, 265.5mm, 266mm, 266.5mm), the diameter of the inscribed circle of the barrel 1 may be 225mm to 240mm (wherein, the diameter of the inscribed circle of the barrel 1 may be 226mm, 227mm, 228mm, 229mm, 230mm, 231mm, 232mm, 233mm, 234mm, 235mm, 236mm, 237mm, 238mm, 239mm), the height of each corrugation segment formed by the corrugations 11 on the same barrel side wall may be 150mm to 180mm (wherein, the height of each corrugation segment may be 155mm, 160mm, 165mm, 170mm, 175mm at the same time), the diameter of the neck of the liquid container may be 50mm to 270mm (wherein, the diameter of the top is 60mm, the top caliber of the neck 3 of the liquid container can be 51mm, 52mm, 53mm, 54mm, 55mm, 56mm, 57mm, 58mm, 59 mm).

In order to make the present liquid container more suitable for use with potable water. Specifically, when barreled drinking water is held on the water dispenser for use, the gradual reduction of the water amount in the barrel inevitably leads to the occurrence of slight unexpected compression deformation of the barrel body 1, thereby leading to the displacement of the gravity center of the water body in the barrel body 1, and at the moment, the liquid container has the hidden trouble of falling from the water dispenser. Therefore, further, the barrel 1 has a polygonal pyramid structure, and the diameter of the circumscribed circle of the barrel 1 gradually increases along the direction of the barrel 1 toward the neck 3. The gravity center of the drinking water barrel can be controlled to be right above the water dispenser as far as possible, so that the liquid container is effectively prevented from falling from the water dispenser.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are within the protection scope of the present invention.
