Description

  The present invention relates to an opening structure for a dispensing nozzle.

  As an unsealing structure that forms a spout in the inner stopper that seals the mouth of the container body that contains the liquid, a cutting groove is formed in the shape of the spout in the inner stopper, and the removal section surrounded by the cutting groove It is known that a pull ring is provided through a support column, and a cutting groove is cut by pulling up the pull ring, and a removal portion is removed together with the pull ring so that a spout is opened (Patent Document 1).

JP 2008-207855 A

  However, in the conventional opening structure using a pull ring, the pulling direction of the pull ring is difficult to be determined in one direction, and depending on the pulling direction, the cutting groove is not cut and the connecting portion of the pull ring and the supporting column or the connecting portion of the supporting column and the removing portion is not provided. It breaks and the spout cannot be opened.

  On the other hand, in order to save the resources and to reduce the price of the product, the contents from the refill container are used to store the contents from the refill container. Refilling is done. When the above-described opening structure of the inner plug is applied to the formation of the spout of such a refill container, the content liquid is discharged in a pulsating manner because the air replacement is not performed smoothly. There arises a problem that the content liquid is unnecessarily bubbles.

  The present invention relates to an unsealing structure having a pulling portion such as a pull ring, so that the spout can be reliably opened by the opening operation by the pulling portion, and the spout formed by the unsealing operation is replaced with air at the time of dispensing. It is an object of the present invention to provide an unsealing structure that can smoothly perform the above.

  The present inventor discharges the liquid from the spout so that it pulsates when the spout formed at one end of the spout nozzle is an oblique spout whose opening surface is inclined with respect to the central axis of the spout nozzle. In this case, if the pulling portion for opening the pouring nozzle is extended from the connecting portion that is erected to the removal portion to the outside of the opening wall that forms the oblique pouring port, the unsealing person At the time of opening, the pulling part is pulled along the oblique spout, so that the pulling direction is stabilized, and when the pulling part is pulled along the slanting nozzle, a moment that makes opening easy works. I found it.

  That is, the present invention is an unsealing structure for a pouring nozzle that is closed, and includes an oblique pouring port whose opening surface is inclined with respect to the central axis of the pouring nozzle at the pouring nozzle side end of the pouring nozzle. An opening wall to be formed, a removal portion that closes the dispensing nozzle on the base side of the dispensing nozzle from the opening surface of the oblique dispensing port, a connecting portion that stands up from the removing portion, and extends from the connecting portion to the outside of the opening wall An opening structure having a tensioned portion is provided.

  According to the opening structure of the present invention, the pulling portion extends outside the opening wall forming the oblique outlet, so that the unsealing person can use the oblique outlet as a guide and the tensile portion as the oblique outlet. Since it is pulled along, the direction of pulling stabilizes in the direction that crosses the oblique spout. Therefore, the pulling portion or the connecting portion that connects it to the removal portion is not unnecessarily twisted and broken, and the dispensing nozzle can be reliably opened.

  Furthermore, since the pulling portion is pulled along the oblique outlet, a moment acting on the lever principle can be obtained at the opening start portion of the removing portion, so that the removing portion is surely removed and the dispensing nozzle is opened. be able to.

  In addition, since the spout at the end of the spout nozzle is an oblique spout whose opening surface is inclined with respect to the central axis of the spout nozzle, the refill container can be provided by providing this spout nozzle in the refill container. When refilling the contents liquid from the container to the container, the dispensing nozzle can be easily inserted into the mouth of the container, and the contents liquid dispensed through the dispensing nozzle is suppressed in pulsation and is smoothly discharged. To maintain. Therefore, it is difficult for the content liquid to spill during refilling, and it is possible to prevent inadvertent foaming.

Hereinafter, the present invention will be described in detail with reference to the drawings. In each figure, the same numerals indicate the same or equivalent components.

  FIG. 1A is a perspective view of a refill container 1 having an opening structure 30 </ b> A according to an embodiment of the present invention in a cap part 3, FIG. 1B is a cross-sectional view taken along line XX of the cap part 3, and FIG. FIG. 1D is a front view of the cap portion 3.

  The refill container 1 has a refill container main body 2 having a bottomed cylindrical shape, and has a cap portion 3 that is screwed into an upper mouth portion of the refill container main body 2. The dispensing nozzle 10 whose tip is closed protrudes. In addition, the refill container main body 2 consists of a blow molding bottle, and the pouring nozzle 10 is resin-molded integrally with the cap part 3.

  The pouring nozzle 10 has an opening wall 12 that forms an oblique pouring port 11 whose opening surface is inclined with respect to the central axis Lo of the pouring nozzle 10 at the end of the pouring port 10. The inclination of the opening surface of the oblique outlet 11 is that the pulsation of the poured liquid is suppressed, and the pulling portion 17 described later is pulled obliquely upward along the oblique outlet 11 so as to longitudinally cut the oblique outlet 11. In view of facilitating this, as shown in FIG. 1B, it is preferable that the angle θ formed by the central portion of the opening surface of the oblique spout 11 with the central axis Lo of the spout nozzle 10 is 30 to 60 °.

  The opening wall 12 forming the oblique outlet 11 is formed with a notch 13 in which the opening wall 12 is partially lacking in a well shape up to the formation surface of the removal portion 14.

  The removing unit 14 closes the dispensing nozzle 10 on the base side of the dispensing nozzle 10 with respect to the opening surface of the oblique dispensing port 11. In this case, the removing portion 14 is a plate surface that is substantially perpendicular to the central axis Lo of the dispensing nozzle 10. In this way, the spout is an oblique spout 11 that is inclined with respect to the central axis Lo of the spout nozzle 10, but the removal portion 14 is formed by a plate surface that is substantially perpendicular to the same central axis Lo. The molding of the dispensing nozzle 10 becomes easy and the molding accuracy can be improved.

  The removal unit 14 is surrounded by an easy cutting unit 15. As shown in FIG. 1B, the easy-cut portion 15 is formed from a thin portion whose wall thickness is reduced by a groove provided from the inside. In addition to the thin portion, the easy-cut portion 15 may be formed by a thin portion in which the wall thickness of the easy-cut portion 15 is thinned from the front and back, or may be formed by a half cut or the like. Moreover, the thin part which forms the easily cut part 15 can be formed continuously or intermittently.

  In the removal portion 14 on the lower end side of the oblique spout 11, a short strip-like connection portion 16 stands on a portion adjacent to the above-described notch 13. The connecting portion 16 is bent and passes through the notch 13, and a pulling portion 17 is extended to the end portion thereof. Here, the width L1 (FIG. 1D) of the gap between the connecting portion 16 and the opening portion wall 12 formed by the notch 13 is to make it difficult for the pulling direction of the pulling portion 17 to sway from the direction that crosses the oblique outlet 11. It is preferable to form narrowly, for example, 0.5 mm to 5 mm.

  The length of the connecting portion 16 and the height of the opening wall 12 from the removing portion 14 are adjusted so that the oblique spout 11 serves as a guide when the pulling portion 17 is pulled up. More specifically, as shown in FIG. 2 (b), at the start of the cutting of the removing portion 14, the connecting portion side end portion 17 a of the pulling portion 17 is located near the notch 13 side edge of the oblique spout 11. It is preferable. Further, as shown in FIG. 2 (d), the connecting portion side end portion 17 a of the pulling portion 17 comes near the tip portion of the oblique spout 11 immediately before the removing portion 14 is removed from the dispensing nozzle 10. In other words, in a state immediately before the removal portion 14 is removed from the dispensing nozzle 10, the total height L4 of the removal portion 14 and the connecting portion 16 is the height of the opening wall 12 from the removal portion 14. It is preferable that it is approximately the same as the length L3. For this reason, the total length L2 of the pulling portion side end portion 16c of the connecting portion 16 and the oblique outlet end portion side end portion of the removal portion 14 and the height of the opening wall 12 from the removal portion 14 L3 is preferably L3 / L2 = 0.5 to 2, more preferably 0.8 to 1 (see FIG. 2A).

  Further, by pulling up the pulling portion 17 along the oblique outlet 11 so as to cut the oblique outlet 11 longitudinally, the connecting portion side end 17a of the tensile portion 17 is near the notch 13 side edge of the oblique outlet 11 (Fig. 2 (b)), the connecting portion side end 17a of the pulling portion 17 is always on the edge of the opening wall 12 while moving to the vicinity of the tip end portion of the oblique outlet 11 (Fig. 2 (d)). The height of the opening wall 12 is increased from the notch 13 side toward the distal end side of the oblique outlet 11 so that the center of the opening surface of the oblique outlet 11 can be The angle θ formed with the central axis Lo is preferably 30 to 60 ° (FIG. 1B).

  The connecting part 16 stands up only from the removing part 14 without standing up across the removing part 14 and the easy-cutting part 15 outside the removing part 14. Further, since the notch 13 is formed to be narrow, the removal portion side end portion of the connecting portion 16 is surrounded by the opening portion wall 12 on the inner side of the opening portion wall 12, and the connecting portion 16 is It arrange | positions so that the inside of the extraction | pouring nozzle 10 may be straddled from the inner side.

  The thickness D1 in the radial direction of the discharging nozzle at the removal portion side end of the connecting portion 16 is preferably equal to or greater than the radial thickness D2 of the discharging nozzle at the pulling portion side end of the connecting portion 16. It is more preferable that the thickness D1 at the removal portion side end of 16 is larger than the thickness D2 at the pulling portion side end (FIG. 1B). As a result, when the pulling portion 17 is pulled as will be described later, the removal portion central portion side end portion 16a of the connecting portion 16 pushes the removal portion 14, and the easily cut portion side end portion 16b opposite to the pushing portion is leveraged. Lifting in principle, and shear stress concentrates on the easily cut portion 15 in the vicinity thereof, so that the easily cut portion 15 can be easily broken (FIG. 2B). Note that the thickness D1 at the removal portion side end of the connecting portion 16 and the thickness D2 at the pulling portion side end change during the opening operation, but the thickness here is not subjected to external stress. Thickness of time.

  Arrow indications P1 and P2 are provided on the outer surfaces of the removing portion 14 and the connecting portion 16 as symbols indicating the direction in which the pulling portion 17 is pulled when the dispensing nozzle 10 is opened.

  In the present embodiment, the entire tension portion 17 is located outside the opening wall 12 of the dispensing nozzle 10 and is formed into a ring-shaped finger ring 18. The finger ring 18 has an outer diameter larger than the inner diameter of the pouring nozzle 10 so that the finger ring 18 can be easily pulled, and it is possible to put the finger on the finger ring 18 through the finger.

  In addition, the pulling portion 17 hangs along the side surface of the dispensing nozzle 10. When the pulling portion 17 protrudes above the oblique outlet 11, when the refill container 1 falls from the pouring nozzle 10 side to the floor, the pulling portion 17 collides with the floor surface, so that the easy cutting portion 15 Although there is a concern that the breakage may occur unnecessarily, the pulling portion 17 hangs down along the side surface of the pouring nozzle 10, whereby such unnecessary breakage of the easily cut portion 15 can be prevented.

  The tip of the pulling portion 17 is connected to the top surface of the cap portion 3 that is a base surface on which the pouring nozzle 10 stands up so that it can be easily separated by hand. Thereby, it is possible to prevent the finger hook ring 18 from being bent around the middle of the transport of the refill container 1 and being accidentally opened. In addition, as a method of securing the pulling portion 17 along the pouring nozzle 10 in this way, the tip end portion of the pulling portion 17 may be detachably connected to the side surface of the pouring nozzle 10.

  This unsealing structure 30A unseals the pouring nozzle 10 that is closed by the following unsealing operation. First, as shown in FIG. 2 (a), the pulling portion 17 formed on the finger ring 18 of the opening structure 30A is separated from the top surface of the cap portion 3, the finger is put on the finger ring 18, and the finger is hooked according to the arrow indication P1. The ring 18 is pulled up, and the upper and lower surfaces of the finger ring 18 are reversed and further pulled up (FIG. 2B). As a result, the removal portion 14 is pushed obliquely downward at the removal portion center side end portion 16a of the connection portion 16, and the easy cutting portion side end portion 16b of the connection portion 16 opposite to the removal portion 14 is lifted by the lever principle. Moment works, and the easily cut portion 15a of the portion is easily broken to become an opening start portion. Subsequently, when the pulling portion 17 is lifted obliquely upward so as to cut the oblique outlet 11 according to the arrow indication P2, the breakage of the easy-cut portion 15 spreads. Here, the opener can pull up the pulling portion 17 diagonally upward (in the direction of arrow a) along the oblique outlet 11 (FIG. 2 (c), FIG. 4 (a), FIG. 5 (a)). In other directions, the pulling portion 17 and the notch side end portion 12a of the opening portion wall 12 interfere with each other, so that it is difficult to pull up. In particular, in this embodiment, the removal portion side end portion 16a of the connecting portion 16 is surrounded by the opening wall 12, and the connecting portion 16 is disposed so as to straddle from the inside of the pouring nozzle 10 to the outside. The connecting portion side end 17a is located in the vicinity of the notch 13 side edge portion of the oblique outlet 11 at the start of cutting of the removing portion 14, and immediately before the removing portion 14 is removed from the outlet nozzle 10, the oblique outlet 11 The opening portion wall is positioned so that the connecting portion side end portion 17a of the pulling portion 17 moves along the edge portion of the opening portion wall 12 between the start of cutting of the removing portion 14 and immediately before the removal portion. 12 is adjusted so that the pulling portion 17 can be removed both when the easy-cutting portion 15a is opened (FIG. 2B) and when the easy-cutting portion 15a is subsequently broken (FIG. 2C). One where the pulling direction cuts the oblique outlet 11 Hard to shake from, to stabilize. Accordingly, it is possible to prevent tearing between the pulling portion 17 and the connecting portion 16 and tearing between the connecting portion 16 and the removing portion 14 that occur when the connecting portion 16 is twisted and pulled up.

  On the other hand, when the pulling portion 17 is pulled up and there is no oblique spout 11 along which the pulling portion 17 extends, the pulling portion 17 is moved in various directions as indicated by arrows a, b1, and b2 in FIG. Can be pulled, the pulling direction is not fixed. Accordingly, it is difficult to eliminate the fact that the connecting portion 16 is twisted when the pulling portion 17 is pulled up, and the pulling portion 17 and the connecting portion 16 are torn or the connecting portion 16 and the removing portion 14 are torn. Further, as shown in FIG. 5B, even if the opening wall 12 forming the oblique spout is formed, the removal portion side end of the connecting portion 16 is poured because the notch 13 is formed widely. Even in the case of being outside the outlet nozzle 10, the pulling portion 17 can be pulled in various directions as indicated by arrows a, b1, and b2, so that the pulling direction is not fixed.

  Thus, by pulling up the pulling portion 17 and removing the removing portion 14, the dispensing nozzle 10 can be opened (FIG. 2 (d)). FIG. 3 is a perspective view of the dispensing nozzle 10 opened by removing the removing unit 14.

  The refill container 1 with the dispensing nozzle 10 opened can be used for refilling the content liquid A into the main container 5 as shown in FIG. 17A. In this refilling operation, as shown in FIG. 17B, the oblique outlet 11 of the refill container 1 is inserted into the mouth of the main container 5, the refill container 1 is inverted, and the refill container 1 and the main container 5 are connected. Make it independent. If the refill container 1 or the main container 5 is a self-supporting columnar container, there is no need to hold the refill container 1 or the main container 5 during such a refilling operation, and the work of refilling work is eliminated. It can be greatly reduced. Furthermore, since the spout of the refill container 1 is the oblique spout 11, air replacement is performed smoothly during the spout. For this reason, the pulsation of the content liquid A can be suppressed at the time of pouring, and the content liquid A can be smoothly refilled from the refill container 1 to the main container 5. Therefore, it is possible to prevent the content liquid A from spilling or being unnecessarily foamed in the container 5. For example, when the viscosity of the content liquid A is 500 mPas to 10000 mPas, the inner diameter of the pouring nozzle 10 is set to 12 to 20 mm, and the oblique angle θ of the oblique outlet 11 is set to 40 to 50. It becomes remarkable when it is set to °.

  The unsealing structure of the present invention can take various forms. For example, the opening structure 30B shown in FIG. 6 is obtained by smoothly raising the opening wall 12 from the lacking portion of the opening wall 12 in place of the well-shaped notch 13 of the opening structure 30A of FIG. 1A. In terms of stabilizing the pulling direction of the pulling portion 17, the notch 13 of the opening structure 30A is preferable.

  The opening structure 30 </ b> C in FIG. 7 is obtained by eliminating the well-shaped notch 13 from the opening structure 30 </ b> A in FIG. 1A and surrounding the entire periphery of the removal portion 14 with the opening wall 12. Thus, even if the entire periphery of the removal portion 14 is surrounded by the opening wall 12, the pulling portion 17 is moved along the oblique outlet 11 by reducing the height of the opening wall 12 in the vicinity of the connecting portion 16. Therefore, it is possible to stabilize the pulling direction.

  The opening structure 30D of FIG. 8A is different from the opening structure 30A of FIG. 1A in that the thickness D3 of the region 21 located in the opening direction from the base of the connecting portion 16 is the removal portion 14 with respect to the thickness of the removal portion 14. The thickness is thicker than the thickness D4 of the other region, and FIG. 8B is a top view of the opening structure 30D. By providing the thick region 21 in this way, it is possible to suppress the removal portion 14 from being bent as shown in FIG. 9A when the pulling portion 17 is pulled up and opened. On the other hand, when the removing portion 14 is easily bent, the removing portion 14 is easily bent when the pulling portion 17 is pulled up, as shown in FIG. Then, as shown in FIG. 9A, if the removal portion 14 is difficult to bend, the removal portion 14 can be easily lifted with the easy-cutting portion 15b in the pulling direction as a fulcrum by the pulling-up portion 17 being pulled up. The removal part 14 can be removed by breaking the part 15.

In the opening structure of the present invention, the pulling portion 17 can be formed of a flexible resin, and the finger ring 18 that forms the pulling portion 17 can have various shapes.
For example, the opening structure 30E of FIG. 10A is obtained by forming the finger ring 18 into an elliptical ring with a flexible resin. If the finger ring 18 is a circular ring and is formed of a rigid resin, the height from the top surface of the cap portion 3 to the connecting portion 16 is sufficient when the dispensing nozzle 10 is short. As a result, the diameter of the circular ring forming the finger ring 18 becomes small, and it becomes difficult to hook the finger. On the other hand, when the finger ring 18 is an oval ring using a flexible resin as in the opening structure 30E of FIG. 10A, the major axis can be adjusted to a ring diameter that allows easy finger engagement. Accordingly, it is possible to ensure the ease of putting a finger on the finger ring 18.

  When the finger ring 18 is formed from a flexible resin, the ring shape is not particularly limited. For example, as shown in the opening structure 30F in FIG. 10B, the ring shape may be a bowl shape, and is shown in the opening structure 30G in FIG. 10C. Thus, it may be a rectangle.

  The opening structure 30H in FIG. 11 is the outer side of the opening wall 12 without causing the finger ring 18 forming the pulling portion 17 to hang down along the side surface of the dispensing nozzle 10 with respect to the opening structure 30A in FIG. Thus, the ring surface of the finger ring 18 is provided so as to be substantially parallel to the removal unit 14 obliquely above the removal unit 14. Also in this unsealing structure 30H, the pulling portion 17 is provided outside the opening portion wall 12, and the length of the connecting portion 16 and the removal portion 14 so that the pulling portion 17 can be pulled along the oblique outlet 11 The height of the opening wall 12 is adjusted. Therefore, the pulling direction of the pulling portion 17 can be stabilized.

  The opening structure 30I in FIG. 12 is obtained by changing the standing position of the connecting portion 16 in the removing portion 14 to the upper end side of the oblique spout 11 with respect to the opening structure 30H in FIG. In this unsealing structure 30I, substantially half of the pulling portion 17 is located outside the opening portion wall 12. As described above, in the present invention, the fact that the tension portion is extended outside the opening wall is not limited to the case where the entire tension portion 17 is provided outside the opening wall 12. As long as the pulling portion 17 can be pulled, a part of the pulling portion 17 may be located inside the opening wall 12.

  In the opening structure 30I, the pulling portion 17 is pulled down in the direction of the arrow when the dispensing nozzle 10 is opened. The length of the connecting portion 16 and the height of the opening wall 12 from the removing portion 14 are different from each other. It is adjusted so as to be along the oblique outlet 11 when 17 is lowered. Therefore, also in this opening structure 30I, the pulling direction of the pulling portion 17 can be stabilized.

  The opening structure 30J in FIG. 13 is obtained by projecting the upper end portion of the dispensing nozzle 10 in a spout shape in the opening structure 30I in FIG. Even if it projects in a spout shape, it can be refilled stably without pulsation.

  The opening structure 30 </ b> K in FIG. 14 is obtained by extending the connecting portion 16 in the opening structure 30 </ b> I in FIG. 12 so that the entire pulling portion 17 is provided outside the opening wall 12. Thereby, it becomes easy to put a finger on the pulling portion 17.

  The opening structure 30L of FIG. 15 is a spherical fitting for the distal end portion of the pulling portion 17 in place of the detachable joint between the distal end portion of the pulling portion 17 and the top surface of the cap portion 3 in the opening structure 30A of FIG. The convex member 19 is provided, and the fitting concave member 20 to be fitted to the fitting convex member 19 is provided on the top surface of the cap portion 3 so that the pulling portion 17 and the cap portion 3 are detachable.

An opening structure 30M in FIG. 16 is obtained by forming the removal portion 14 substantially parallel to the opening surface of the oblique spout 11 in the opening structure 30A in FIG. 1A. As described above, the angle of the plate surface constituting the removal portion 14 can be an angle from approximately perpendicular to the central axis L ₀ of the dispensing nozzle 10 to approximately parallel to the opening surface of the oblique outlet 11. it can.

  The present invention can take various modes. For example, in the opening structure of the present invention, the pulling portion 17 is not limited to the ring-shaped finger-hanging portion, and may be a plate shape.

  Moreover, the opening structure of this invention is not restricted to being formed in the extraction nozzle protruded from the cap part. For example, you may form in the extraction nozzle which protruded directly from the top | upper surface of the refill container main body. In this case, an opening is provided at the bottom of the refill container body, the content liquid is filled into the refill container body from the opening at the bottom, and the bottom opening is sealed by heat sealing or the like after filling.

  Further, each opening structure described above may be covered with a protective cover that detachably covers it. Furthermore, the constituent elements of the respective opening structures described above can be appropriately combined.
