Description

Technical Field

[0001] The utility model belongs to a packaging container and its accessories, which are a disposable cover and a conveying mechanism with a straw and a packaging bottle, and a packaging bag with such a conveying mechanism, and relates to an improvement of the cover structure. Specifically, after the cover body is unscrewed, it can still be connected to the connecting ring by a connecting strip, and further, it can be recycled together with the conveying mechanism or packaging container used therewith. Background Art

[0002] Traditionally, in disposable flexible packaging bags, the screw cap is fixed by a connecting ring and a bayonet of a conveying mechanism, and the conveying mechanism and the mouth of its straw are closed by the screw cap, while the screw cap itself and the connecting ring are connected by a pre-breaking point. When the screw cap is unscrewed, the pre-breaking point will be torn, thereby obtaining a disposable mark. At the same time, the cap can be separated from the straw to expose the mouth of the straw for people to take out the contents from the flexible packaging bag.

[0003] However, this screw cap still has a disadvantage, that is, after being unscrewed, it is separated from the packaging container and is easy to be lost. In particular, for soft-packaged beverages for children, the screw cap may be swallowed by children by mistake. Moreover, the loss of the screw cap is not conducive to the recycling of waste materials, which has a great impact on environmental protection. Summary of the invention

[0004] The utility model aims to provide a screw cap, a conveying mechanism and a packaging bag and a packaging bottle thereof, wherein the screw cap can still be connected to a connecting ring after being torn at a pre-breaking point, so that a conveying mechanism or a packaging container using the screw cap can still be connected to the conveying mechanism or the packaging container after opening and is not easy to be lost, which is beneficial to preventing children from swallowing by mistake and the one-time recycling of waste products.

[0005] The rotary cover of the utility model is realized by the following scheme:

[0006] A screw cap comprises a cover body, a connecting ring, and a marking strip for marking disposable use. The marking strip is characterized in that the marking strip is an open ring and is located between the cover body and the connecting ring. The two ends of the marking strip are respectively connected and fixed to the cover body and the connecting ring, and the upper and lower surfaces of the marking strip are respectively connected to the cover body and the connecting ring at pre-break points with gaps.

[0007] In this way, the cover body can be fixed to the mouth of the container or the conveying mechanism through the connecting ring, the mouth is closed by the cover body, and whether the pre-breaking point of the marking strip is broken is used as an indicator of whether the container or the conveying mechanism has been used.

[0008] In addition, when the cover body is rotated to open relative to the connecting ring, the pre-breaking points on the upper and lower sides of the marking strip will be torn from the cover body and the connecting ring due to the torque force to meet the requirements of the cover body rotating and rising. At the same time, the marking strip will ensure that the cover body is connected to the connecting ring, making it difficult for the cover body to be lost.

[0009] The conveying mechanism of the utility model is realized by the following scheme:

[0010] A conveying mechanism includes a straw with a bayonet formed at the lower part. The mechanism is characterized in that it also includes the above-mentioned screw cap, which is fixed by a connecting ring and the bayonet. The screw cap and the straw are screwed together, and the cover body closes the mouth of the straw.

[0011] In this way, when the cover is opened, the marking strip can ensure that the cover is connected to the conveying mechanism, so that the cover is not easily lost.

[0012] The packaging bag of the utility model is realized by the following scheme:

[0013] A packaging bag comprises a bag body and is characterized in that it also comprises the above-mentioned conveying mechanism, and the periphery of the bag body opening is heat-sealed to the sealing position of the conveying mechanism.

[0014] In this way, when the cover is opened, the marking strip can ensure that the cover is connected to the bag body, so that the cover is not easily lost.

[0015] The packaging bottle of the utility model is realized by the following scheme:

[0016] A packaging bottle comprises a bottle body, and is characterized in that it also comprises the above-mentioned screw cap, which is fixed by a connecting ring and a bayonet of the bottle body, the screw cap and the bottle body are matched through threads, and the mouth of the bottle body is closed by the cover body.

[0017] In this way, when the cover is opened, the marking strip can ensure that the cover is connected to the packaging bottle, so that the cover is not easily lost.

[0018] The screw cap, conveying mechanism and packaging bag and packaging bottle created by the present invention can be torn from the cap and the connecting ring by the pre-breaking points on the upper and lower sides of the marking strip under the action of torsion when the cap is rotated to open relative to the connecting ring, thereby serving as a one-time use mark.

[0019] The utility model discloses a screw cap, a conveying mechanism, a packaging bag and a packaging bottle, when the cover body is rotated to open relative to the connecting ring, the pre-breaking points on the upper and lower sides of the marking strip are gradually torn from the cover body and the connecting ring by the torsional force, so that the marking strip releases its elasticity, and the requirement that the cover body is separated from the mouth and rises can be met at the same time.

[0020] With the screw cap, conveying mechanism, packaging bag and packaging bottle thereof, when the cover is rotated to open relative to the connecting ring, the pre-breaking points on the upper and lower sides of the marking strip are peeled off from the cover and the connecting ring by the action of torque, but the two ends of the marking strip are still fixed to the cover and the connecting ring. Thus, the cover can be ensured not to be lost easily, which is beneficial to preventing children from swallowing by mistake and enabling one-time recycling.

[0021] In addition, the screw cap, conveying mechanism, and packaging bag and packaging bottle thereof, after the cover body is opened during use, the marking strip is fixed together with the cover body and the connecting ring, and the marking strip is annular and elastic, which can meet the requirements of the cover body being rotated in the opposite direction to cooperate with the straw to close the mouth, and the marking strip can still be between the cover body and the connecting ring, so as to facilitate people's requirements for temporarily closing the mouth during use.

[0028] The specific implementation structure of the utility model is described in detail below with reference to the accompanying drawings:

[0029] Reference Figures 1 to 5 The flexible packaging bag comprises a conveying mechanism A and a bag body B, and the conveying mechanism A comprises a screw cap C and a straw D. Among them: the screw cap C has a cover body 1 that matches with the straw D; a connecting ring 2 that matches and fixes with the bayonet of the straw D; and a marking strip 3 for marking disposable use; the marking strip 3 is an open ring, located between the cover body 1 and the connecting ring 2, and the two ends of the marking strip 3 are respectively fixed to the cover body 1 and the connecting ring 2 through fixing points 31 and 32, and the upper and lower sides of the marking strip 3 are respectively connected to the cover body 1 and the connecting ring 2 through pre-break points 33 with gaps. The straw D has a mouth 4 formed at the upper part and a bayonet 5 formed at the lower part. With the matching of the connecting ring 2 and the bayonet 5, the cover body 1 and the straw D can be fixed together by threaded connection, and the cover body 1 can seal the mouth 4 of the straw D, so as to obtain the conveying mechanism A. Then, the bag body B can be heat-sealed around the opening 7 of the bag body B at the sealing position 6 of the straw D, so as to obtain a flexible packaging bag.

[0030] Reference Figure 4When the cover body 1 rotates counterclockwise, the pre-breaking points 33 on the connecting line 3 will be peeled off from the cover body 1 and the connecting ring 2 respectively, so that the cover body 1 can be rotated and raised, so that the cover body 1 can be separated from the mouth 4 of the straw D for use. At the same time, the connecting line 3 can still connect the cover body 1 and the connecting ring 2 together through the fixing points 31 and 32. Since the connecting ring 2 is clamped at the clamping point 5 of the straw D, and the sealing position 6 of the bag body B and the straw D is fixed, even if the flexible packaging bag is discarded after use, the cover body 1 will always be connected to the bag body B for easy recycling.
