Description

Technical Field

[0001] The utility model relates to the technical field of toothpaste tubes, in particular to a leak-proof and reliably sealed packaging hose. Background Art

[0002] A toothpaste tube is used to package toothpaste. It is usually in a tubular shape and has an opening at one end. The toothpaste is squeezed out through the opening. The opening is covered with a lid. The lid is used to cover the opening of the toothpaste tube to seal the toothpaste tube. However, the current toothpaste tube has the following shortcomings: although tin foil is placed at the opening of the toothpaste tube to seal the opening after the toothpaste is filled in the tube, the tin foil will be torn off after the toothpaste is used for the first time. The lid and the opening of the toothpaste tube are usually threaded, and the lid and the toothpaste tube are both hard objects. The connection between the lid and the toothpaste tube can be regarded as a "rigid connection", so there will be a gap between the lid and the toothpaste tube, making it difficult to achieve effective sealing. Utility Model Content

[0003] In view of the problems existing in the existing leak-proof and reliably sealed packaging hose, the utility model is proposed.

[0004] Therefore, the purpose of the utility model is to provide a leak-proof and reliably sealed packaging hose, which solves the problem that although tin foil is set at the opening of the existing toothpaste tube to seal the opening after the toothpaste is filled into the toothpaste tube, the tin foil will be torn off after the toothpaste is used for the first time, and the cover and the opening of the toothpaste tube are usually threadedly connected, and the cover and the toothpaste tube are both hard objects. The connection between the cover and the toothpaste tube can be regarded as a "rigid connection", so a gap will appear between the cover and the toothpaste tube, making it difficult to achieve effective sealing.

[0005] In order to solve the above technical problems, according to one aspect of the present invention, the present invention provides the following technical solutions:

[0006] A leakproof and reliably sealed packaging hose comprises a packaging hose body, the top of the packaging hose body is provided with an opening, a cover is connected to the opening, a sealing ring is provided on the opening, and a connecting structure is provided between the opening and the cover;

[0007] The opening and the cover are butted against each other through a connecting structure and squeeze the sealing ring.

[0008] As a preferred solution of the leak-proof and reliably sealed packaging hose described in the utility model, an outer support ring is integrally provided on the opening, and the sealing ring is sleeved on the opening and located between the cover and the outer support ring.

[0009] As a preferred solution of the leak-proof and reliably sealed packaging hose described in the utility model, the connection structure includes an internal threaded hole on the cover, an external thread on the top outer wall of the opening, and the opening and the cover are threadedly connected.

[0010] As a preferred solution of a leak-proof and reliably sealed packaging hose described in the utility model, the connection structure includes a plug-in groove on the cover, an L-shaped buckle integrally provided on the bottom of the cover, a first through hole on the sealing ring and a second through hole on the outer support ring.

[0011] As a preferred solution of the leak-proof and reliably sealed packaging hose described in the utility model, a buckle portion is integrally provided at the bottom of the L-shaped buckle.

[0012] As a preferred solution of a leak-proof and reliably sealed packaging hose described in the utility model, the first through hole and the second through hole are respectively the first circular hole and the second circular hole. When the cover and the opening are connected, the buckle part passes through the first circular hole and the second circular hole and is clamped on the bottom of the outer support ring.

[0013] As a preferred solution of a leak-proof and reliably sealed packaging hose described in the utility model, the first through hole and the second through hole are respectively the first wedge-shaped long hole and the second wedge-shaped long hole. When the cover and the opening are connected, the buckle part passes through the first wedge-shaped long hole and the second wedge-shaped long hole and is stuck at the bottom of the outer support ring.

[0014] Compared with existing technologies:

[0015] 1. By arranging an outer support ring on the opening of the packaging hose body and sleeved with a sealing ring on the outer support ring, when the lid and the opening are butted against each other through the connection structure between the lid and the opening, the sealing ring will be compressed, thereby realizing elastic sealing between the lid and the opening by using the sealing ring, thereby ensuring the sealing effect between the lid and the packaging hose body;

[0016] 2. The modification to the existing packaging hose body is very small, so the structure is simple and suitable for popularization and use; the seal between the cover and the opening is achieved by setting a buckle structure, which can avoid the situation where the seal between the cover and the opening is damaged due to the loose thread connection of the cover, and the use is more reliable and convenient.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clear, the implementation methods of the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Embodiment 1:

[0028] The utility model provides a leak-proof and reliably sealed packaging hose. Figure 1-2 , comprising a packaging hose body 1, the top of the packaging hose body 1 is provided with an opening 11, the opening 11 is connected to a cover 3, the opening 11 is provided with a sealing ring 2, and a connecting structure is provided between the opening 11 and the cover 3;

[0029] The opening 11 and the cover 3 are connected via a connecting structure and squeeze the sealing ring 2. The sealing ring 2 is made of rubber material. Therefore, when the rubber sealing ring 2 is squeezed by the cover 3 and the outer support ring 12 on the opening 11, the sealing between the cover 3 and the opening 11 can be effectively achieved.

[0030] An outer support ring 12 is integrally provided on the opening 11 , and the sealing ring 2 is sleeved on the opening 11 and is located between the cover 3 and the outer support ring 12 .

[0031] The connection structure includes an internal thread hole 31 on the cover 3 and an external thread on the top outer wall of the opening 11 , and the opening 11 and the cover 3 are threadedly connected.

[0032] During specific use, the sealing ring 2 is put on the outer support ring 12, the cover 3 is threadedly connected to the opening 11, and the cover 3 is tightened to squeeze the sealing ring 2 together with the sealing ring 2, so that the sealing ring 2 is deformed to achieve sealing between the opening 11 and the cover 3.

[0033] Embodiment 2:

[0034] See attached Figure 3-6 , which is different from Example 1, is that: the connection structure includes a plug-in groove 32 provided on the cover 3, an L-shaped buckle 33 integrally provided at the bottom of the cover 3, a first through hole provided on the sealing ring 2 and a second through hole provided on the outer support ring 12. Specifically, the first through hole and the second through hole are respectively the first circular hole 21 and the second circular hole 121. When the cover 3 and the opening 11 are connected, the buckle portion 331 passes through the first circular hole 21 and the second circular hole 121 and is clamped at the bottom of the outer support ring 12; the bottom of the L-shaped buckle 33 is integrally provided with a buckle portion 331, and when the L-shaped buckle 33 is clamped at the bottom of the outer support ring 12, the sealing ring 2 is squeezed between the cover 3 and the outer support ring 12.

[0035] During specific use, the sealing ring 2 is put on the outer support ring 12, the cover 3 is covered on the opening 11, and the buckle part 331 passes through the first circular hole 21 on the sealing ring 2 and the second circular hole 121 on the outer support ring 12. In the process of the buckle part 331 entering the first circular hole 21, the first circular hole 21 contacts the inner wall of the first circular hole 21, and the L-shaped buckle 33 is deformed due to the squeezing of the inner wall of the first circular hole 21. When the buckle part 331 completes passing through the first circular hole 21 and the second circular hole 121, the L-shaped buckle 33 recovers its deformation and is stuck at the bottom of the outer support ring 12. At the same time, the sealing ring 2 is squeezed and deformed between the cover 3 and the outer support ring 12.

[0036] Embodiment 3:

[0037] See attached Figure 7-8 , which is different from Example 2, is that the first through hole and the second through hole are respectively the first wedge-shaped long hole 22 and the second wedge-shaped long hole 122. When the cover 3 and the opening 11 are docked, the buckle portion 331 passes through the first wedge-shaped long hole 22 and the second wedge-shaped long hole 122 and is stuck at the bottom of the outer support ring 12. Similarly, when the L-shaped buckle 33 is stuck at the bottom of the outer support ring 12, the sealing ring 2 is squeezed between the cover 3 and the outer support ring 12; at this time, the lengths of the first wedge-shaped long hole 22 and the second wedge-shaped long hole 122 are longer, so that when the cover 3 is covered on the opening 11, it can be easier to pass through the sealing ring 2 and the outer support ring 12, so that the cover 3 is easier to cover the opening 11.

[0038] During specific use, the sealing ring 2 is put on the outer support ring 12, the cover 3 is covered on the opening 11, and the buckle part 331 passes through the first circular hole 21 on the sealing ring 2 and the second circular hole 121 on the outer support ring 12. In the process of the buckle part 331 entering the first circular hole 21, the first circular hole 21 contacts the inner wall of the first circular hole 21, and the L-shaped buckle 33 is deformed due to the squeezing of the inner wall of the first circular hole 21. When the buckle part 331 completes passing through the first circular hole 21 and the second circular hole 121, the L-shaped buckle 33 recovers its deformation and is stuck at the bottom of the outer support ring 12. At the same time, the sealing ring 2 is squeezed and deformed between the cover 3 and the outer support ring 12.

[0039] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
