Description

Technical Field

[0001] The invention belongs to the technical field of locking bottles and bottle caps, and particularly relates to a milk bottle with a bottle cap that automatically locks after a set time limit has passed. Background Art

[0002] As a nutritious drink, milk is consumed by a large proportion of the elderly and children. However, milk needs to be consumed within the shelf life. Milk that exceeds the shelf life is very easy to deteriorate and will cause harm to the human body after drinking. Ultra-high temperature sterilized milk uses high temperature sterilization and generally has a shelf life of 6-9 months. Other dairy beverages generally have a shelf life of 12 months. Existing milk packaging bottles mainly focus on improvements to improve sealing performance and hygiene, such as the Chinese utility model patent with authorization announcement number CN203997382U, which discloses a milk packaging bottle that can prevent the inner cover and folding tableware from being contaminated, enhances safety of use, and is more convenient to use; the outer cover and the inner cover fit tightly together and are not easily damaged during transportation, making them easy to transport.

[0003] Ultra-high temperature sterilized milk has a long shelf life, and people often buy it in boxes to give to relatives and friends and for family reserves. As a result, it is more likely to be stored for too long and exceed the shelf life. Children are not very aware of whether their drinks are expired and generally do not check it. The elderly are also less likely to check it because of the deterioration of vision and memory. Therefore, these two groups of people are at higher risk of accidentally drinking spoiled milk.

[0004] In addition, bottled milk drinks generally require a straw when drinking, and the straw is usually placed separately, which requires searching for when drinking, which is inconvenient. Alternatively, the straw is glued to the outside of the bottle with glue, which makes it easy for the glued position to break and cause the straw to be lost. Summary of the Invention

[0005] In response to the above-mentioned problem, the present invention provides a milk bottle with a bottle cap that automatically locks after a set period has passed. The milk bottle can automatically operate within a certain range of the set period, making it impossible for the drinker to open the bottle cap normally, thereby forcing the drinker to temporarily give up drinking or check the production date. If it is determined that the milk is still within the shelf life, the drinker can open the bottle cap and drink it by pressing a designated part and rotating the bottle cap at the same time.

[0006] The object of the present invention is achieved through the following technical solution: a milk bottle with a bottle cap that automatically locks after a set period of use has expired, comprising: a bottle body, a bottle cap threadedly connected to the bottle body, at least one set of overdue locking components provided on the outer surface of the neck of the bottle body, and a two-stage threaded structure provided on the mouth of the bottle body;

[0007] The two-stage thread structure includes a fixed thread section fixed to the upper section of the mouth and a threaded rotating body tightly and rotatably sleeved on the lower section of the mouth; the threaded rotating body is composed of a thread section located at the upper part and a rotating body located at the lower part. The inner contour of the rotating body is closely connected to the outer surface of the neck of the bottle body, and the outer surface of the neck is a rotating body; the bottle mouth has a sealing film, and a straw receiving groove is provided on the outer surface of the bottle body, which vertically penetrates the entire bottle body. The outer peripheral surface of the bottle body is affixed with an advertising layer;

[0008] Under normal circumstances, the threaded rotor is positioned in the appropriate position by the over-expiration locking component. The appropriate position specifically refers to a continuous and complete thread line formed with the thread line of the fixed thread segment. At this time, the internal thread of the bottle cap can be engaged with or separated from the complete thread line; the over-expiration locking component also has the function of automatically invalidating the lock after a certain period of time. After the lock fails, the bottle cap is rotated, and the threaded rotor will rotate accordingly because it is not locked, thereby causing the thread line to be misaligned, restricting the drinker from opening it.

[0009] Preferably, when the threaded element and the fixed thread segment form a continuous and complete thread, the thread segment at the intersection of the two is partially missing. When the unlocked threaded element approaches the fixed thread segment as the bottle cap rotates, the missing portion provides space for the threaded element to move, thereby preventing the upper and lower threads from being misaligned and the bottle cap from being locked.

[0010] Preferably, the overdue locking components are arranged in two groups, symmetrically across the diameter of the bottle body. The symmetrical arrangement of the two overdue locking components can better secure the threaded rotating body. The unlocking operation is similar to that of a single group and is equally convenient.

[0011] Preferably, the peripheral surface of the threaded rotating body near the lower edge has a locking portion for positioning. Providing the locking portion at this position can more conveniently achieve the fixing of the threaded rotating body.

[0012] Preferably, the overdue locking assembly includes a component mounting portion located at the neck of the bottle body, wherein a compression spring, a rigid-flexible column pusher, a sublimable solid ball, and a locking actuator are sequentially arranged in the component mounting portion from the inside out. The rigid-flexible column pusher is composed of a coaxially connected cylindrical flexible member and a cylindrical rigid member. The diameter of the central section of the cylindrical flexible member is smaller than that of the remaining section. The free end of the cylindrical rigid member has an arcuate inner concave surface for pressing against the sublimable solid ball. The arcuate inner concave surface provides a large contact surface with the sublimable solid ball, preventing it from being damaged by the thrust of the compression spring. The position of the sublimable solid ball is also not affected by normal transportation, handling, or handling.

[0013] Preferably, the component mounting portion is composed of a sinking platform, an avoidance hole in the plane of the sinking platform, a component mounting hole in the avoidance hole, and a limiting groove on each side wall of the sinking platform. The compression spring falls into the component mounting hole, and the end of the compression spring facing outward is connected to the free end of the cylindrical flexible part.

[0014] Preferably, the locking portion is triangular in shape, with a mounting hole formed in the middle of the triangle. The two oblique sides of the triangle can block in both rotation directions, so the triangular shape is simple and practical. In addition, the mounting hole formed in the middle allows the blocking components to be conveniently assembled through only one mounting hole without interfering with each other.

[0015] Preferably, the locking actuator is integrally formed, including a blocking portion that matches the two upward edges of the locking portion, a sliding portion extending downward in the middle of the blocking portion, a width slightly smaller than the installation through hole, and the same thickness as the installation through hole, a cylindrical receiving portion at the end of the sliding portion, and a limiting portion provided on the periphery of the receiving portion; the limiting portion and the limiting groove both have the same curvature, and after installation, there is a gap above the limiting groove, in which an elastic block is installed. When the sublimable solid ball sublimates to a certain size, the middle section of the cylindrical flexible member enters the avoidance hole. When the bottle cap is screwed, the blocking portion is subjected to force, causing the middle section of the cylindrical flexible member and the elastic block to deform simultaneously. The displacement of the locking actuator is equivalent to loosening the threaded rotating body. When the twisting force is loosened, the middle section of the cylindrical flexible member and the elastic block restore the locking actuator to its original position, and the threaded rotating body also returns to its original position, thereby preventing the process of opening the bottle cap and resetting it as a whole. There is no unnecessary movement, which is very convenient.

[0016] Preferably, one end of the receiving portion, facing the component mounting portion, is a receiving hole, and the other end is a release press. The release press and the sliding portion are integrally structured, with the release press surrounding the inner wall of the receiving hole, with the upper portion reserved and the remainder cut along the inner wall arc. The entire release press is attached to the sliding portion, making it easy to operate.

[0017] Preferably, the unlocking pressing portion is made of plastic and has elasticity.

[0018] Preferably, the receiving hole is used to receive the front end of the cylindrical rigid member and the sublimable solid ball together, and the outer wall of the cylindrical rigid member is tightly slidably connected to the inner wall of the receiving hole. The tight sliding connection facilitates smooth reset of the cylindrical rigid member when the unlocking pressing portion is pressed.

[0019] Preferably, the sublimable solid balls are mothballs. Although the sublimation time of the sublimable solid balls may vary due to environmental stability, we advance the warning time, that is, the mothballs sublime to trigger protection before the expiration date, so as to remind the drinker to check the expiration date and achieve the purpose of safe consumption.

[0020] Preferably, the accommodating groove is bent and extended to the bottom of the bottle, and an inclined block for accommodating the straw head is provided in the sink. A hole matching the diameter of the straw is provided at the bottom of the inclined block, and the outer surface is flush with the outer surface of the neck of the bottle body and has a smooth transition.

[0021] In summary, the present invention has the following advantages compared with the prior art:

[0022] The present invention aims to improve the milk bottle commonly used on the market, where the bottle body and bottle cap are threadedly connected. By providing at least one set of expired locking components on the outer surface of the bottle neck and a two-stage threaded structure at the mouth of the bottle, the two components cooperate to automatically activate within a certain range of a set expiration date, making it impossible for the drinker to open the bottle cap normally, forcing the drinker to temporarily give up drinking or check the production date. If it is determined that the bottle is still within the shelf life, the drinker can press a designated part and rotate the bottle cap at the same time to open and drink. The present invention uses an advertising layer to provide the drinker with instructions on how to unlock and reopen the bottle cap. The advertising layer also serves to securely cover the straw.

[0023] The locking of the present invention does not require additional actions, but it cannot achieve precise control over the shelf life. Therefore, it mainly serves to pre-lock the bottle cap when approaching the end of the shelf life. In this way, an unlocking structure needs to be set to reopen the bottle cap for drinking. For this purpose, the unlocking structure designed by us only requires the drinker to press the designated position with two fingers when holding the bottle body, which is no different from the usual bottle opening habit. Therefore, there are no cumbersome steps in the user experience and it is easily accepted by the public. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0039] Example 1

[0040] like Figure 1-4 As shown, a milk bottle with a bottle cap that automatically locks after a set expiration date is exceeded comprises: a bottle body 1, a bottle cap 2 threadedly connected to the bottle body 1, at least one set of expiration locking components 11 provided on the outer surface of the neck of the bottle body 1, and a two-stage thread structure 12 provided on the mouth of the bottle body 1;

[0041] The two-section thread structure 12 includes a fixed thread section 121 fixed to the upper section of the mouth and a threaded rotating body 122 tightly and rotatably sleeved on the lower section of the mouth; the threaded rotating body 122 is composed of a threaded section 2a located at the upper part and a rotating body 2b located at the lower part. The inner contour of the rotating body 2b is fitted and connected to the outer surface of the neck of the bottle body 1. The outer surface of the neck is a rotating body, and the shape is preferably cylindrical or conical.

[0042] Under normal conditions, the threaded rotating body 122 is positioned by the extended locking assembly 11 to a proper position, specifically forming a continuous and complete thread line with the thread line of the fixed thread segment 121. At this time, the internal thread of the bottle cap 2 can be engaged with or separated from the complete thread line.

[0043] The overdue locking component 11 also has the function of automatically invalidating the lock after a certain period of time. After the lock is invalidated, the bottle cap 2 is rotated, and the threaded rotating body 122 will rotate accordingly because it is not locked, thereby causing the thread line to be misaligned, restricting the drinker from opening it. It should be noted that if Figure 12 As shown, when the threaded rotating body 122 and the fixed thread segment 121 form a continuous and complete thread line, the thread line at the intersection of the two is partially missing. The purpose of setting the missing is to ensure that when the threaded rotating body 122 is not locked, the threaded rotating body 122 can be rotated according to the rotation direction of the threaded rotating body 122. Figure 12 When the screw is turned in the loosening direction, the missing portion provides space for the screw rotating body 122 to rotate, thereby causing the thread of the screw rotating body 122 to be misaligned. When the screw rotating body 122 is turned in the tightening direction, the missing portion is enlarged, and the thread is also misaligned. In other words, when the screw rotating body 122 is not locked, the bottle cap 2 can only rotate within a very small range and cannot be opened. The effective threads of the fixed thread section 121 and the screw rotating body 122 are both more than two turns to ensure meshing friction when the bottle cap 2 is threaded.

[0044] The expired locking component 11 also has an unlocking function. This is because the component for setting the deadline has a certain error. When setting the deadline, the deadline needs to be advanced. In this way, the drinker is forced to check first and confirm that it has not expired before continuing to open and drink in an unlocked manner.

[0045] The overdue locking components 11 are preferably arranged in two groups opposite to each other through the diameter of the bottle body 1, which is beneficial to providing a relatively balanced locking force.

[0046] like Figure 5-10 As shown, the circumference of the threaded rotating body 122 near the lower edge has a locking portion 2c for positioning; the overdue locking component 11 includes a component mounting portion 1a located at the neck of the bottle body 1, and a compression spring 1b, a rigid-flexible column pusher 1c, a sublimable solid ball 1d, and a locking actuator 1e are arranged in sequence from the inside to the outside in the component mounting portion 1a; the rigid-flexible column pusher 1c is composed of a coaxial fixed combination of a cylindrical flexible component c1 and a cylindrical rigid component c2, and the diameter of the middle section of the cylindrical flexible component c1 is smaller than that of the other parts The free end of the cylindrical rigid member c2 has an arc-shaped concave surface for pressing the sublimable solid ball 1d; the component mounting portion 1a is composed of a sinking platform 01, an avoidance hole 04 in the sinking platform plane, a component mounting hole 02 in the avoidance hole 04, and a limiting groove 03 on each side wall of the sinking platform 01. The compression spring 1b falls in the component mounting hole 02, and the end of the compression spring 1b facing outward is connected to the free end of the cylindrical flexible member; the cylindrical flexible member can be an elastic material in the prior art, preferably a rubber material.

[0047] like Figure 2As shown, the locking portion 2c is preferably in the shape of a triangle, which can provide positioning blocking in two rotation directions, is simple and practical, and a mounting through hole 2c1 is provided in the middle of the triangle. The locking actuator 1e is integrally formed, and includes a blocking portion e1 that matches the two upward edges of the locking portion 2c. In the middle of the blocking portion e1, there is a sliding portion e2 that extends downward, has a width slightly smaller than the mounting through hole 2c1, and has the same thickness as the mounting through hole 2c1. At the end of the sliding portion e2 is a cylindrical accommodating portion e3, and on the outer periphery of the accommodating portion e3 is provided a limiting portion e4 that limits its displacement along the Y-axis direction of the coordinate axis and allows tight sliding in the directions of the Z and X axes; that is, the limiting portion e4 and the limiting groove 03 have the same curvature, and the material of the limiting portion e4 is preferably hard plastic, so that when the limiting portion e4 is displaced in the limiting groove 03, because it also has a slight upward movement, the limiting portion e4 is required to have a certain rebound performance after deformation. After installation, there is a gap above the limiting groove 03, and an elastic block e5 is installed in the gap, see Figure 6 ;

[0048] One end of the accommodating portion e3 toward the component mounting portion 1a is a accommodating hole e7, and the other end is an unlocking pressing portion e6; the unlocking pressing portion e6 and the sliding portion e2 are an integral structure, and the unlocking pressing portion e6 surrounds the inner wall of the accommodating hole e7 and is cut with the remaining arc at the top, see Figure 7 The unlocking pressing part e6 is made of plastic and has elasticity. The unlocking pressing part e6 can be pressed downward. After pressing, the plate surface tilts downward. After releasing, the plate surface recovers. The accommodating hole e7 is used to accommodate the front end of the cylindrical rigid member c2 and the sublimable solid ball 1d to enter together. The outer wall of the cylindrical rigid member c2 is tightly slidably connected with the inner wall of the accommodating hole e7. The sublimable solid ball 1d is preferably odorless mothballs in this embodiment. After the overall installation, Figure 6 As shown, the compression spring 1b, the cylindrical flexible member c1 of the rigid-flexible integrated column push member 1c, and a portion of the cylindrical rigid member c2 are located in the component mounting hole 02, and the other portion of the cylindrical rigid member c2 and the sublimable solid ball 1d are located in the receiving hole e7;

[0049] The action principle of sublimable solid ball 1d is: Figure 6 This is the initial state of the milk bottle when the milk drink leaves the factory. The cylindrical rigid component c2 is in the component mounting hole 02. At this time, the locking actuator 1e is in a rigid connection state, the threaded rotating body 122 is locked, and the bottle cap 2 can be unscrewed and tightened at will. As the sublimable solid ball 1d gradually sublimates and becomes smaller over time, the compression spring 1b pushes the rigid-flexible column pusher 1c forward until the sublimable solid ball 1d is reduced to a certain size. See Figure 11At this time, the middle section (the part with a smaller diameter) of the cylindrical flexible part c1 is pushed to the position of the avoidance hole 04. At this time, the bottle cap 2 is rotated, and the threaded rotating body 122 will rotate with the friction of the thread line. The limiting part e4 is driven to squeeze the elastic block e5, and the cylindrical flexible part c1 and the accommodating part e3 are also displaced in the avoidance hole 04, and then the upper and lower thread lines are misaligned and stuck. Since the threads of the bottle mouth are reinforced, ordinary manpower will not damage the thread lines. At this time, the advertising layer 004 can be written with a reminder to inform the drinker to check the shelf life and inform him that if it is within the shelf life, he should press and hold the unlocking press part e6 and continue to rotate the bottle cap 2 to open it. At this time, the hand releases the bottle cap 2, and the elastic block e5 causes the locking actuator 1e to return to the initial position. At this time, pressing the unlocking press part e6 will force the cylindrical rigid part c2 back into the component mounting hole 02, so that the locking actuator 1e is restored to a rigid connection, and the bottle cap 2 can be opened or tightened.

[0050] The existing well-known bottle mouth has a sealing film, which needs to be poked with a straw 001 for drinking. The straw 001 is usually placed separately or glued to the outside of the bottle with glue, which is easy to lose. For this reason, a straw receiving groove 002 is provided below one of the sinks 01, which vertically penetrates the entire bottle body. The receiving groove 002 is bent and extends to the bottom of the bottle. The purpose is that if a straw 001 with a bend is placed, the bent section can be placed at the bottom of the bottle. An inclined block 003 for accommodating the head of the straw is provided in the sink 01. A hole matching the diameter of the straw 001 is provided at the bottom of the inclined block 003. The outer surface is flush with the outer surface of the neck of the bottle body 1 and has a smooth transition, so as to guide the finger when pressing the unlocking pressing part e6.

[0051] In the prior art, an advertising layer 004 is pasted on the outer peripheral surface of the bottle body 1 . The advertising layer 004 just covers the straw 001 when pasted, so that the straw 001 can be better kept together with the bottle body 1 .

[0052] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope of the appended claims.
