Description

Technical Field

[0001] This utility model relates to the field of dental handpiece packaging technology, and more specifically, to a special plastic sealing bag for dental handpieces. Background Technology

[0002] Dental handpieces, also known as dental handpieces, are different from everyday handpieces. They are specialized medical instruments used in dentistry to clean tartar and polish decayed teeth. There are many types of handpieces, which can be divided into high-speed and low-speed handpieces based on their rotation speed and structure. After use, dental handpieces often need to be cleaned and packaged for storage, usually in plastic bags.

[0003] Existing plastic sealing bags for dental handpieces are prone to leakage at one end of the handpiece due to insufficient drying when placed inside after cleaning. This causes liquid to drip inside the plastic sealing bag and spread as the handpiece moves, affecting the cleanliness of the storage and making it difficult to absorb the dripping oil. Therefore, a special plastic sealing bag for dental handpieces is proposed. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a special plastic sealing bag for oral handpieces to solve the problems mentioned in the background art.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] As attached Figure 1-5The dental handpiece sealing bag shown includes a plastic bag body 1. Both ends of the plastic bag body 1 are equipped with heat-sealing lines 2 to improve the sealing and fixing strength. One end of the inner cavity of the plastic bag body 1 is equipped with oil-absorbing cotton 5, which can absorb and clean the residual oil in the placed dental handpiece, preventing the oil from spreading inside the plastic bag body 1 and improving the use effect. On the two sides of the plastic bag body 1 away from the oil-absorbing cotton 5, a sealing mother strip 3 and a sealing daughter strip 4 are fixedly connected. The sealing mother strip 3 and the sealing daughter strip 4 can be used to re-seal after the heat-sealing line 2 is opened, making it easy to open and close. The side of the plastic bag body 1 near the sealing mother strip 3 is fixedly connected with a hanging ear 6, which makes it easy to hang and store the plastic bag containing the dental handpiece for convenient use.

[0027] In this embodiment, two sealing strips 3 and two sealing strips 4 are provided, with the two sealing strips 3 arranged side by side, see [reference]. Figure 1 As shown, the bottom sealing strip 3 has a first notch, while two sealing strips 4 are arranged side by side. The bottom sealing strip 4 has a corresponding second notch. When the bottom sealing strip 3 and sealing strip 4 are fastened together, the first and second notches overlap, allowing the inner cavity of the plastic bag body 1 to remain connected to the outside. This allows air to be squeezed out of the plastic bag body 1 after a handpiece is placed inside, preventing expansion due to air inside the plastic bag body 1. After the air is squeezed out of the plastic bag body 1, the top sealing strip 3 and sealing strip 4 are then fastened together, thus sealing the inside of the plastic bag body 1.

[0028] The plastic bag body 1 has anti-collision sealing edges 7 on both sides through heat sealing. Reinforcing cotton pads 8 are provided on the outer surfaces of both sides of the middle section of the plastic bag body 1. The plastic bag body 1 includes a PET substrate 9, an antibacterial layer 10 disposed inside the PET substrate 9, and a protective film 11 disposed outside the PET substrate 9. The antibacterial layer 10 is the inner layer of the plastic bag body 1, and the protective film 11 is the outer layer of the plastic bag body 1. The PET substrate 9 is an interlayer of the plastic bag body 1, and a flexible layer is provided between the PET substrate 9 and the protective film 11. The anti-collision sealing edges 7 can protect the plastic bag. The two sides of the body 1 are sealed for protection, and the bulges in the middle of both sides of the plastic bag body 1 are protected against impact by the reinforcing cotton pads 8. The antibacterial layer 10 can inhibit the growth of microorganisms and reduce the risk of infection of the internal items due to packaging contamination. This ensures that the oral handpiece is in a sterile environment during packaging, improving the storage and use effect. The protective film 11 and the flexible layer 12 can improve the puncture resistance, impact resistance and tensile strength of the plastic bag body 1, preventing the oral handpiece from being damaged by collision during storage and transportation, thus improving the use effect.

[0029] See Figure 4As shown, in this embodiment, the flexible layer 12 between the PET substrate 9 and the protective film 11 is mainly formed by woven metal wires. The metal wires are woven into a mesh shape, and each cell of the mesh is arranged in a triangular pattern. This improves the stability of the flexible layer 12. Because the flexible layer 12 uses elastic metal wires, it can deform to a certain extent and form a protective layer. When it is impacted by external sharp objects or touched by the sharp part of the mouthpiece itself, the flexible layer can play a protective role, preventing the sidewall of the plastic bag body 1 from being punctured and improving its service life. Furthermore, the flexible layer can deform without affecting the normal opening or closing of the plastic bag body 1.

[0030] In another embodiment, the flexible layer 12 can be provided in two layers, located on both sides of the PET substrate 9, protecting the PET substrate 9 between the two flexible layers 12. This can protect the PET substrate 9, so that the PET substrate 9 will not be damaged regardless of whether the plastic bag body 1 is subjected to external impact or internal impact, so that the plastic bag body 1 can always remain sealed and avoid being punctured.

[0031] As attached Figure 1-5 As shown, the protective film 11 is made of high-strength, wear-resistant polyester material, and the antibacterial layer 10 is made of antibacterial PE material that inhibits the growth of microorganisms. The sealing strip 3 and the sealing strip 4 are located near the middle of the plastic bag body 1 on the heat-sealing line 2, which is the opening of the plastic bag body 1. The oil-absorbing cotton 5 is pasted and fixed to the middle of one end of the plastic bag body 1. An oil drain hole is opened on the outside of the side of the plastic bag body 1 near the oil-absorbing cotton 5. A sealing film is pasted on one side of the plastic bag body 1 at the position corresponding to the oil drain hole. The sealing strip 3 and the sealing strip 4 are compatible. There are two of each of the sealing strip 3 and the sealing strip 4. A retaining strip is provided at one end of the sealing strip 4. A retaining groove is opened on one side of the sealing strip 3. The retaining strip and the retaining groove are compatible to seal the opening at the other end of the plastic bag body 1. By cooperating with the sealing strip 3 and the sealing strip 4, a secondary seal can be achieved after the heat-sealing line 2 is opened, through the locking of the sealing strip 3 and the sealing strip 4, improving the storage effect and facilitating secondary recycling. The oil-absorbing cotton 5 can absorb and clean the residual oil in the placed dental handpiece, preventing the oil from spreading inside the plastic bag body 1 and improving the usage effect. With the oil drain hole, after absorbing the residual oil in the stored dental handpiece, the dental handpiece can be removed, the sealing film can be opened, and then the oil-absorbing cotton 5 can be pressed to drain the oil through the oil drain hole, facilitating recycling. The sealing film can also be used to easily seal the oil drain hole.

[0032] The working principle of this utility model is as follows: When in use, the oral handpiece is placed inside the plastic bag body 1, with the end of the oral handpiece positioned close to the oil-absorbing cotton 5. When residual oil drips out of the oral handpiece, it can be absorbed by the oil-absorbing cotton 5, keeping the inside of the plastic bag body 1 clean and tidy. Then, the opening is sealed by the sealing mother strip 3 and the sealing daughter strip 4 to improve the sealing effect.

[0033] By reinforcing the cotton pads 8 to protect the bulging areas on both sides of the plastic bag body 1 from impact, and by using the antibacterial layer 10 to inhibit the growth of microorganisms and reduce the risk of infection of the stored items due to packaging contamination, the oral handpiece is kept in a sterile environment during packaging, improving the storage and use effect. Furthermore, the combination of the protective film 11 and the flexible layer 12 can improve the puncture resistance, impact resistance, and tensile strength of the plastic bag body 1, preventing damage to the oral handpiece due to impact during storage and transportation, and improving the use effect.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
