Description

Technical Field

[0001] The invention belongs to the technical field of packaging containers, and particularly relates to a bottle cap. Background Art

[0002] In recent years, with the demand for increased portability in life, bottle caps have become a very important necessity in the composition of containers in daily life. Some bottle caps currently in use on the market, such as edible oil bottles, seasoning bottles, wine bottles, beverage bottles, chewing gum bottles, etc., have structures such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, Figure 1 It is a schematic diagram of a three-dimensional structure in which the flip cover and the main cover card of the existing bottle cap are integrated into one; Figure 2 A schematic diagram of opening the flip cover of an existing bottle cap in which the flip cover and the main cover are integrated into one by snapping; Figure 3 It is a schematic diagram of the structure in which the flip cover and the main cover of the existing bottle cap are integrally formed; Figure 4 A schematic diagram of opening the flip cover of an existing bottle cap in which the flip cover and the main cover are integrally formed; Figure 1 , Figure 2 , Figure 3 and Figure 4 The bottle cap in the figure is matched with the bottle by a single flip cover 2, or the independent flip cover 2 is matched with the bottle after being clamped into an independent main cover 1, or the flip cover 2 and the main cover 1 are formed in one piece and matched with the bottle through the main cover 1. The function of the main cover 1 is to match the bottle to form a pouring mouth. Some main covers 1 on the market are provided with a pull ring structure 5 for opening the pouring mouth. The function of the flip cover 2 is to protect the pouring mouth or the bottle mouth of the main cover 1 from being polluted by the outside world. Since it is opened by flipping, a connecting belt 3 is provided between the flip part and the fixed part of the above bottle caps. The connecting belt 3 is directly provided on the flip cover 2, and is also provided between the flip cover 2 and the main cover 1. At the same time, a first protrusion 4 is generally provided on the diagonal side of the flip cover connecting belt 3 relative to the center to facilitate the operator to get his fingers stuck and have a fulcrum when opening the flip cover. The operator opens the cover by first clamping the first protrusion 4 with a finger and then applying force in the opening direction until the cover is opened. The cover is opened by rotating around a certain point on the connecting belt 3 as a rotation point. After the cover is opened, the top of the cover can be closed by pressing the finger.

[0003] When the bottle cap is used normally, the user holds the bottle body with one hand and opens the flip cover with the other hand to pour out the contents of the bottle, or stands the bottle on a table and opens the flip cover with one hand and then holds the bottle again to pour out the contents of the bottle. After use, the user presses the top of the flip cover with a finger to close it.

[0004] The methods of opening the flip cover of the above products currently on the market generally require two hands to work together or one hand to operate in two steps, and the steps of both methods are relatively complicated. Since it is necessary to use force to open the flip cover, the first protrusion 4 on the outer side of the flip cover is generally located away from or diagonally to the connecting belt 3, which is also the position of the pouring outlet of the bottle. If the bottle contains liquid, this place is often the most easily contaminated by the liquid. Once contaminated, the fingers will also be contaminated when they touch this position during subsequent use.

[0005] Therefore, it is necessary to provide a bottle cap to overcome the shortcomings of the above-mentioned bottle cap, that is, the process of opening the bottle cap and then pouring out the bottle contents is relatively cumbersome and fingers are easily contaminated. Summary of the invention

[0069] like Figure 33-37 The third elastic structure 50 is used to make the flip cover 2 have an automatic rebound closing function. Fig.33 It is a schematic diagram of the structure of another form of the bottle cap of the present invention being separated by being engaged on the flip cover through an elastic structure; Fig.34 It is a schematic diagram of the structure of another form of the bottle cap of the present invention being assembled by engaging the elastic structure on the flip cover; Fig.35 It is a schematic diagram of the anatomical structure of another form of the bottle cap of the present invention, which is assembled by snapping the elastic structure onto the flip cover; Fig.36 It is a schematic diagram of the structure of another form of the bottle cap of the present invention, which is assembled and opened by engaging the elastic structure on the flip cover; Fig.37 Schematic diagram of the anatomical structure of another form of the bottle cap of the present invention, which is assembled and opened by the elastic structure. In the figure, a horizontal bar 53 is set at the hollow position in the middle of the pressing part 10 of the flip cover 2, and a third protrusion 54 is set below the peripheral connecting belt 3 of the flip cover 2. One end of the third elastic structure 50 has a groove structure 51, and the other end is a protrusion structure 52, and the middle is a U-shaped elastic structure. The installation method is that the third protrusion 54 on the flip cover 2 is engaged with the groove 51 on the third elastic structure 50, and the protrusion structure 52 at the other end is stuck on the flip cover pressing part 10, and the middle U-shaped bypasses the horizontal bar 53 on the pressing part 10 ( Figure 33-37 ), the third elastic structure 50 is separately installed on the flip cover 2, but it can make the flip cover have independent rebound ability.

[0070] The bottle cap provided in this embodiment is a bottle cap that can be easily opened by flipping the cover. Since a pressing component that can be hooked by fingers is provided on one side of the connecting belt on the flip cover, when using a small bottle, the operator can first hold the bottleneck of the bottle with his hand, and then hook the protruding part of the structure on the flip cover with his index finger. By hooking it hard, the flip cover can be directly opened with one point on the connecting belt as the rotation point. After pouring the contents of the bottle, the pressing component on the flip cover can be directly pushed with the index finger to close the flip cover. For a large bottle, when the large bottle is in an upright state, the operator can directly press the pressing component of the flip cover with his fingers, and directly open the flip cover with one point on the connecting belt as the rotation axis. After pouring the contents of the bottle, the bottle can be erected again, and then the protruding part of the flip cover can be hooked with the fingers to close the flip cover.

[0071] In the present embodiment, when the Chinese main cover is provided with a pull ring structure, the pull ring structure is thickened and reinforced with ribs to increase its strength. When in use, the flip cover can be opened by hand in the original manner and then the pull ring can be pulled open. The pulled pull ring structure can then be inserted into the groove at the top of the flip cover that can hold the pull ring. The flip cover can be opened by directly hooking the pull ring with a finger.

[0072] In this embodiment, elastic material is used to make the connecting belt elastic. When in use, just hook the raised part of the flip cover with your fingers to tilt the bottle when the flip cover is in the open state. After tilting, the flip cover will automatically return to its original position due to elasticity when the fingers are removed.

[0073] The technical solution of the present invention is very suitable for mold making and high-speed production in terms of structure and use, is more hygienic and convenient, is convenient for daily use, saves the complexity of opening the bottle cap with two hands, and avoids the disadvantage of liquid contamination to the hands.

[0074] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the relevant field can still modify or replace the specific implementation methods of the present invention with equivalents. Any modifications or equivalent replacements that do not depart from the spirit and scope of the present invention are within the scope of protection of the pending claims.
