Description

TECHNICAL FIELD

[0001] The utility model relates to but not limited to container packaging technical field, especially a liquid press bottle with anti -rotation structure. BACKGROUND

[0002] In the design of traditional press bottle, the pump head and the bottle mouth realize sealing through extrusion gasket. Opening the elbow depends on the friction between the bottle and the gasket. Specifically, the elbow is installed on the main column, and the main column and the lock cover are connected through the threaded structure. The thread of the bottle cap part and the bottle body are engaged with each other, further locking the whole structure. However, when the friction between the bottle and the gasket is not enough to overcome the friction between the main column and the lock cover, the pump head will rotate with the elbow, and further drive the thread to rotate, which will damage the locking relationship between the thread and the bottle body, and may cause the bottle to loosen or leak. The bottle mouth is easy to leave material body, especially oily material body, which will significantly reduce the effective friction between the bottle and the gasket, so that the anti-rotation mechanism depending on the friction is invalid. When trying to open the elbow, the pump head is more likely to rotate with the elbow, further damaging the locking of the thread and the bottle body. SUMMARY

[0037] The utility model embodiment is further described below with reference to the drawings.

[0038] Refer to Figures 1-2 , Figure 1 It is the main sectional view of the liquid pressing bottle with the anti-rotation structure provided by an embodiment of the utility model. The liquid pressing bottle comprises a bottle body 110 and a pump head 120, the first tooth-shaped structure 111 is designed on the upper edge of the bottle mouth of the bottle body 110, and the second tooth-shaped structure 121 is arranged at the connecting part of the pump head 120 and the bottle mouth, and the first tooth-shaped structure 111 and the second tooth-shaped structure 121 can form the anti-rotation structure 1210 of the pressing bottle by mutual cooperation. The elbow 130 of the pressing bottle is fixedly installed on the main column 140, and the main column 140 and the lock cover 150 are stably locked and connected through the thread structure. The screw thread 160 of the bottle cap can be engaged with the corresponding structure of the bottle body 110, so that the locking effect of the whole pressing bottle is further enhanced. In the process of opening the elbow 130, the user only needs to exert a small screw thread locking force, so that the screw thread tightly presses the pump head 120, and the first tooth-shaped structure 111 and the second tooth-shaped structure 121 are engaged with each other, effectively preventing the rotation of the pump head 120 relative to the bottle mouth, so that the elbow 130 can be smoothly opened. In addition, in order to ensure that the connection between the bottle mouth and the pump head 120 has good sealing performance, the sealing structure 1220 is additionally arranged at the connecting part. In the embodiment, as shown in the drawing, Figure 2As shown, the first toothed structure 111 is located on the upper end circumferential surface of the upper edge of the bottle mouth, and the second toothed structure 121 is located on the first outer circumferential surface of the pump head 120. The first toothed structure 111 comprises a plurality of protrusions 210 which are evenly distributed on the upper end circumferential surface, and each protrusion 210 is provided with an abutting surface 211 on one side. Correspondingly, the second toothed structure 121 comprises a plurality of ratchets 220 which cooperate with the protrusions 210. When the elbow 130 of the press bottle is unlocked and attempted to be loosened, although the pump head 120 can be subjected to a rotating force, at this time the abutting surface 211 can quickly and effectively block the ratchet 220, thereby preventing the pump head 120 from rotating relative to the bottle mouth, and ensuring the integrity of the locking relationship between the screw thread 160 and the bottle body 110, reducing the risk of bottle loosening or leakage. It is worth noting that one side of the second toothed structure 121 is also provided with a circumferential wall 230, and the outer side surface of the circumferential wall 230 is connected with the second toothed structure 121. When the pump head 120 is connected with the bottle mouth, the circumferential wall 230 can be closely abutted with the inner side surrounding wall of the bottle mouth, thereby forming a reliable sealing structure 1220 together. The sealing structure 1220 is mainly realized by the interference fit between the circumferential wall 230 of the pump head 120 and the bottle mouth, ensuring that the press bottle does not leak during use.

[0039] Referring to Figures 3-4 , Figure 3 is a main sectional view of a liquid press bottle with an anti-rotation structure according to another embodiment of the present application. It should be noted that the liquid press bottle in Figure 3 is similar in structure to the press bottle in Figure 1 and has the same functional characteristics. Specifically, Figure 3 the liquid press bottle also comprises a bottle body 310 and a pump head 320. The upper edge of the bottle mouth of the bottle body 310 is provided with a first toothed structure 410, and the pump head 320 is provided with a corresponding second toothed structure 420 at the joint with the bottle mouth. The two sets of toothed structures cooperate with each other to form an anti-rotation structure 3410 of the press bottle. In addition, the elbow 330 of the press bottle is mounted on the main column 340, and the main column 340 and the lock cover 350 can be tightly locked and connected through a threaded structure. The screw thread 360 of the bottle cap is tightly engaged with the corresponding structure of the bottle body 310, further improving the locking stability of the entire press bottle. During the opening of the elbow 330, the user only needs to apply a small screw thread locking force to tightly fit the screw thread with the pump head 320, and to make the first toothed structure 410 and the second toothed structure 420 mesh with each other. This design effectively prevents accidental rotation of the pump head 320 relative to the bottle mouth, ensuring smooth opening of the elbow 330. In order to guarantee the sealing performance of the connection between the bottle mouth and the pump head 320, a sealing structure 3420 is specially added at the connection. As Figure 4As shown, in the present embodiment, the first toothed structure 410 can be arranged on the upper end circumferential surface of the upper edge of the bottle mouth, while the second toothed structure 420 can be arranged on the first outer circumferential surface of the pump head 320. The first toothed structure 410 is composed of a plurality of protrusions 411, and each protrusion 411 is provided with an abutting surface on one side to provide a stable blocking force. The second toothed structure 420 comprises a plurality of ratchets 421 matched with the protrusions 411. When trying to unlock and loosen the elbow 330 of the press bottle, even if the pump head 320 is subjected to a rotating force, the abutting surface can quickly and effectively block the ratchet 421, thereby preventing the rotation of the pump head 320 relative to the bottle mouth, ensuring the integrity of the locking relationship between the screw thread 360 and the bottle body 310, and reducing the risk of bottle loosening or leakage. It is worth noting that the inner side of the second toothed structure 420 is additionally provided with a circumferential wall 422. When the pump head 320 is tightly connected with the bottle mouth, the circumferential wall 422 can tightly fit with the inner side wall of the bottle mouth to form a stable and reliable sealing structure 3420. The core of this sealing structure is that the circumferential wall 422 of the pump head 320 and the bottle mouth are in interference fit, thereby ensuring that the press bottle does not leak during normal use, greatly improving the user experience.

[0040] Referring to Figures 5-6 , Figure 5 is a main sectional view of a liquid press bottle with an anti-rotation structure provided by another embodiment of the present application. In the present embodiment, the first toothed structure 510 is arranged on the inner wall circumferential surface of the upper edge of the bottle mouth and connected with the upper end surface of the groove 512 arranged on the inner wall circumferential surface, thereby ensuring the stability and reliability of the first toothed structure 510. The second toothed structure 520 is located on the first outer circumferential surface of the pump head, and the first toothed structure 510 and the second toothed structure 520 can cooperate to form an anti-rotation structure 5610 of the press bottle. As shown, Figure 6 the first toothed structure 510 is specifically composed of a plurality of protrusions 511, and each protrusion 511 is provided with an abutting surface on one side. Correspondingly, the second toothed structure 520 comprises a plurality of ratchets 521 which can cooperate with the protrusions 511 in the first toothed structure 510. When the pump head is subjected to a rotating force, the abutting surface can abut against the ratchet 521, thereby effectively preventing the rotation of the pump head relative to the bottle mouth. In addition, it is worth noting that the second toothed structure is additionally provided with a circumferential wall 522 on one side, and the outer side surface of the circumferential wall 522 is tightly connected with the second toothed structure 520. When the pump head is tightly connected with the bottle mouth, the circumferential wall 522 can tightly abut against the inner side wall of the bottle mouth, thereby jointly constructing a stable and reliable sealing structure 5620. The sealing structure 5620 not only improves the sealing performance of the press bottle, but also ensures that the user will not encounter the problem of liquid leakage during use.

[0041] Referring to Figures 7-8 , Figure 7 is the main sectional view of the liquid pressing bottle with anti-rotation structure provided by another embodiment of the present utility model. In the embodiment, the first tooth-shaped structure 810 and the second tooth-shaped structure 820 can form the anti-rotation structure 7810 of the pressing bottle by mutual cooperation. Specifically, the first tooth-shaped structure 810 can be arranged on the outer wall circumference of the upper edge of the bottle mouth and be closely connected with the outer wall circumference to form an integral whole. Among them, the first tooth-shaped structure 810 can be composed of multiple protrusions 811, and each protrusion 811 is provided with an abutting surface on one side. At the same time, the second tooth-shaped structure 820 contains multiple ratchets 821, and the ratchets 821 can cooperate with the protrusions 811 in the first tooth-shaped structure 810. When the pump head is subjected to the action of the rotating force, the abutting surface of the protrusion 811 can abut with the ratchet 821 in the second tooth-shaped structure 820, thereby effectively preventing the rotation of the pump head relative to the bottle mouth. In this way, not only the stability of the pressing bottle is improved, but also it is ensured that the user can easily perform the rotation operation of the pump head in the use process, and the pump head will not be accidentally dropped or loosened. In addition, the inner side of the second tooth-shaped structure 820 is provided with a circumferential wall 822. When the pump head is closely matched with the bottle mouth, the circumferential wall 822 can be closely abutted with the inner side of the surrounding wall of the bottle mouth, thereby jointly constructing a reliable sealing structure 7820. Such design not only enhances the sealing performance of the pressing bottle, but also effectively prevents the problem of liquid leakage, and provides the user with a safer and more convenient use experience.

[0042] Referring to Figures 9-10 , Figure 9is a main sectional view of the liquid pressing bottle with the anti-rotation structure provided by another embodiment of the utility model. In the embodiment, the first tooth-shaped structure 1010 and the second tooth-shaped structure 1020 can form the anti-rotation structure 910 of the pressing bottle by mutual cooperation. Specifically, the first tooth-shaped structure 1010 is located on the inner wall circumference of the upper edge of the bottle mouth and is connected with the upper end face of the convex groove 1012 arranged on the inner wall circumference, so that the stability and reliability of the first tooth-shaped structure 1010 can be ensured. The first tooth-shaped structure 1010 can be composed of a plurality of protrusions 1011, and each protrusion 1011 is provided with an abutting surface on one side. At the same time, the second tooth-shaped structure 1020 comprises a plurality of ratchets 1021, and the ratchets 1021 can cooperate with the protrusions 1011 in the first tooth-shaped structure 1010. When the pump head is subjected to a rotating force, the abutting surface can abut against the ratchet 1021, so that the rotation of the pump head relative to the bottle mouth can be effectively prevented, and the stable connection between the pump head and the bottle mouth is ensured. In addition, one side of the second tooth-shaped structure 1020 is provided with a circumferential wall 1022 which is closely connected with the second tooth-shaped structure 1020 to form an integral whole, which not only enhances the structural strength of the second tooth-shaped structure 1020, but also enables the circumferential wall 1022 to abut against the inner side wall of the bottle mouth closely, so as to jointly build a reliable sealing structure 920, thereby effectively preventing the problem of liquid leakage and providing users with a safer and more convenient use experience.

[0043] Referring to Figures 11-12 , Figure 11 is a main sectional view of the liquid pressing bottle with the anti-rotation structure provided by another embodiment of the utility model. In the embodiment, the first tooth-shaped structure 1010 and the second tooth-shaped structure 1020 can form the anti-rotation structure 910 of the pressing bottle by mutual cooperation. Specifically, the first tooth-shaped structure 1010 is located on the inner wall circumference of the upper edge of the bottle mouth and is connected with the upper end face of the convex groove 1012 arranged on the inner wall circumference, so that the stability and reliability of the first tooth-shaped structure 1010 can be ensured. The first tooth-shaped structure 1010 can be composed of a plurality of protrusions 1011, and each protrusion 1011 is provided with an abutting surface on one side. At the same time, the second tooth-shaped structure 1020 comprises a plurality of ratchets 1021, and the ratchets 1021 can cooperate with the protrusions 1011 in the first tooth-shaped structure 1010. When the pump head is subjected to a rotating force, the abutting surface can abut against the ratchet 1021, so that the rotation of the pump head relative to the bottle mouth can be effectively prevented, and the stable connection between the pump head and the bottle mouth is ensured. In addition, one side of the second tooth-shaped structure 1020 is provided with a circumferential wall 1022 which is closely connected with the second tooth-shaped structure 1020 to form an integral whole, which not only enhances the structural strength of the second tooth-shaped structure 1020, but also enables the circumferential wall 1022 to abut against the inner side wall of the bottle mouth closely, so as to jointly build a reliable sealing structure 920, thereby effectively preventing the problem of liquid leakage and providing users with a safer and more convenient use experience.

[0044] Reference Figures 13-14 , Figure 14 This is a front cross-sectional view of a liquid press bottle with an anti-rotation structure according to another embodiment of the present invention. In this embodiment, the first toothed structure 1410 and the second toothed structure 1420 can cooperate with each other to form the anti-rotation structure 1310 of the press bottle. Specifically, the first toothed structure 1410 can be arranged on the upper circumferential surface of the upper edge of the bottle mouth, wherein the first toothed structure 1410 is composed of a plurality of protrusions 1411, and these protrusions 1411 can be grouped and arranged on the upper circumferential surface to achieve more balanced force distribution and more stable connection. Figure 14 As shown, these protrusions 1411 are divided into two groups, each group containing four protrusions 1411, which are symmetrically arranged on the upper circumferential surface. This grouping and symmetrical design not only enhances the stability of the structure but also allows the pump head to engage more smoothly with the bottle neck during rotation. Each protrusion 1411 has a stop surface on one side, which can precisely abut against the ratchet in the second toothed structure 1420 when the pump head is subjected to rotational force, thereby effectively preventing the pump head from rotating relative to the bottle neck. The second toothed structure 1420 contains multiple ratchet teeth 1421 that engage with the protrusions 1411 in the first toothed structure 1410. These ratchet teeth 1421 are designed to form a tight fit with the stop surfaces to ensure a stable connection between the pump head and the bottle neck. In addition, a circumferential wall 1422 is added to one side of the second toothed structure 1420. This circumferential wall 1422 can abut tightly against the inner wall of the bottle mouth when the pump head and bottle mouth are tightly fitted, thus forming a stable and reliable sealing structure 1320. This design not only enhances the sealing performance of the pump bottle, but also effectively avoids the risk of liquid leakage.

[0045] Reference Figures 15-16 , Figure 15is a main sectional view of the liquid pressing bottle with the anti-rotation structure provided by another embodiment of the utility model. In this embodiment, the first tooth-shaped structure 1610 and the second tooth-shaped structure 1620 can form the anti-rotation structure 1510 of the pressing bottle by mutual cooperation. Specifically, the first tooth-shaped structure 1610 can be arranged on the outer wall circumference of the upper edge of the bottle mouth, which can be composed of a plurality of protrusions 1611, and each protrusion 1611 is provided with an abutting surface. At the same time, the second tooth-shaped structure 1620 comprises a plurality of ratchets 1621, which can form cooperation with the protrusions 1611 in the first tooth-shaped structure 1610. When the pump head is subjected to the action of the rotating force, the abutting surface can be in close abutment with the ratchet 1621, thereby effectively preventing the rotation of the pump head relative to the bottle mouth, ensuring the stability of the connection. It is worth noting that one side of the second tooth-shaped structure 1620 is additionally provided with a circumferential wall 1622, which can be in close abutment with the inner side wall of the bottle mouth when the pump head and the bottle mouth are closely matched, thereby forming a stable and reliable sealing structure 1520, which effectively prevents the leakage of liquid. Further, in order to improve the smoothness and ease of use of the connection between the pump head and the bottle mouth, each ratchet 1621 is provided with a guide slope 1623. When the pump head is subjected to the action of the rotating force, the guide slope 1623 can be in contact with the abutting surface first, which not only helps the smooth rotation of the pump head to the right position, but also reduces the friction and resistance in the rotation process to a certain extent, so that the user can enjoy a more smooth and convenient operation experience in the use process.

[0046] It should be noted that the specific shape, structure, etc. of the first tooth-shaped structure and the second tooth-shaped structure in the above embodiments are not strictly limited, as long as the first tooth-shaped structure and the second tooth-shaped structure can be meshed with each other when the pump head is subjected to the action of the rotating force, thereby effectively preventing the rotation of the pump head relative to the bottle mouth. In addition, the size, shape, number, etc. of the protrusions and the ratchets are not limited in the embodiments of the present application, as long as the protrusions can be in close abutment with the ratchets to effectively prevent the rotation of the pump head relative to the bottle mouth. In addition, the specific design of the circumferential wall is also not limited in the embodiments of the present application, as long as it can be closely attached to the inner side wall of the bottle mouth to form a reliable sealing structure (such as the sealing structure 1220). This sealing structure mainly relies on the interference fit between the circumferential wall of the pump head and the bottle mouth to realize, thereby ensuring that the pressing bottle will not leak liquid during use.

[0047] It can be understood that the liquid in the liquid pressing bottle can be shampoo, hair conditioner, shower gel, hand sanitizer, various cosmetic lotions, medicinal liquid, seasoning and liquid food, etc. without more limitation here.

[0048] The above is a specific description of the preferred embodiment of the present application, but the present application is not limited to the above-mentioned embodiments, and those skilled in the art can make various equivalent modifications or replacements without departing from the spirit of the present application, and these equivalent modifications or replacements are all included in the scope defined by the claims of the present application.
