Description

  The present invention relates to the technology of the tip structure of straws and suction instrument devices, and more specifically, the tip structure of the suction portion is not a straight cut, but is cut into an uneven shape, circular shape, wave shape, or the like. Because of the structure of the tip portion having the gap, air can be sucked up from the gap together with moisture to be sucked, and suction can be performed without the suction target remaining on the bottom surface. Furthermore, the present invention relates to a tip structure of suction device devices that can greatly reduce the damage to an object when the force adsorbed to the object such as the inner surface of a beverage container or the inside or outside of a mouth during dental treatment is excessive.

  The present invention has a structure in which when the air pressure in the suction device is lowered, the tip portion having a cut is sucked into the suction device device without resistance, and by having a gap, it functions as a suction port and at the same time becomes a ventilation port. In addition, air flows in and the air pressure in the suction device is restored, and at the same time, the tip of the suction port that has been adsorbed easily peels off, so that a straw for consumer drinks, a vacuum tip for dental treatment in industrial use, or Combined use with endoscopes such as gastrocamera and intestinal camera with vacuum function, suction port of vacuum cleaner, tip nozzle of submersible pump, tip nozzle of vacuum type sampling device such as sewage sludge or manure, bedrock, etc. The present invention relates to a technique of a vacuum nozzle having a suction or water absorption function such as a combined use with a mining drill.

    As for the tip structure of the conventional suction instrument devices, there are an inexpensive product in which the tip is linearly cut in the vertical direction as shown in “FIG. 1” and a product whose tip is inclined as shown in “FIG. 2”. It was a practical technology.

  For example, "Fig. 1" is a common plastic straw used in fast food stores and convenience stores, and "Fig. 2" is a double-pipe drawer attached to beverage brick packs such as juice and milk. The straw-type straw structure is now a straw suction structure that is well known to the standard.

  Patent Document 1 has a double-pipe drawer-type straw structure shown in FIG. The material is made of polypropylene or the like, and the outer tube and the inner tube are slid relative to each other and extended to a predetermined required length. At this time, the flange-shaped ring formed at the base end of the inner tube is the outer tube. Guided by the inclined portion of the rear half of at least one ventilation groove formed in the circumferential direction along the longitudinal direction, it advances smoothly through resin elasticity, springs back at the tip, and the ring at the base end of the inner tube Linearly adheres to the tapered funnel-shaped portion of the outer tube, revealing a sealed state, where the inner tube is pierced through the thin film of the suction hole at the edge opening at the tip of the inner tube, and the inner tube is When inserted into the inside, a concave ventilation groove formed along the longitudinal direction of the outer tube is faced by the thin film, forming a gap, and the inside of the container is brought into communication with the outside air. Drinking beverages such as juice and milk by exerting a suction action on the proximal end, while the container No pressure change occurs, so that the outer shape is not deformed, no abnormal noise is generated, and the proximal end portion of the inner tube is not subject to unexpectedly applying a longitudinal return external force to the straw. The flange-shaped ring is hooked on the stepped portion at the tip of the ventilation groove formed close to the proximal end of the tapered funnel-shaped portion of the outer tube and functions as a stopper, and the return of the inner tube to the outer tube Prevents unnecessary shortening, prevents the last remaining liquid in the container from being fully sucked, ensures that all the beverage is available for drinking, and the outer tube vent groove is aspirated It is the most popular shape with technical means that guarantees the pressure balance inside and outside of the absorber at the time and effectively maintains the predetermined length of the straw, the structure is simple and the cost can be reduced, Is it possible to suck all liquid residue remaining on the bottom without leaving it Speaking, completely not be aspirated.

  Patent Document 2 has a utility model application technique called twin straws. As the name suggests, this twin straw has a structure in which two main straws and sub-straws are formed as one set, and the main straw has a structure in which the tip is subjected to an inclined process, as in Patent Document 1, The secondary straw is only for ventilation. This twin straw specification requires a volume equivalent to two ordinary straws, and is not practically commercially available and economical.

  Patent Document 3 is a large-sized citrus fruit straw that is provided with concave and convex cuts on the suction port and the base end peripheral surface, and in particular, it can efficiently extract the flesh and fruit juice in the fruit bunch. Since this technology product requires the work of twisting the skin of the fruit with the tip of the straw, a metal material such as polycarbonate resin or aluminum alloy is used as the material, so the selling cost per bottle is It is expensive at several hundred yen.

  Patent Document 4 discloses a technique related to a vacuum tip that is attached to the tip for use in vacuuming saliva inside and outside the mouth during dental treatment, and there is a vacuum tip that eliminates the problem that the suction port is adsorbed in the mouth. . However, when the prototype of the cut V-shaped tip is actually made, water pressure is better for soft vinyl plastic materials such as polypropylene or film resin, and the opening / closing timing is not as expected. It has been found that it is difficult to open and close smoothly with a hard metal material unless a significant decompression occurs.
