The present application relates to a dispensing container capable of pop-up removal of wet tissue.

Heretofore, wet tissue dispensing containers are known. For example, Patent Document 1 discloses a wet tissue dispensing container including a container main body having an opening formed on the upper surface, and a lid which can be opened and closed to the opening, the sheet being shaped to cover the opening. The airtight member is disposed, and the airtight member is provided with an outlet for wet tissue and a convex portion arranged to surround the periphery of the outlet, and the inner surface of the lid is annularly erected so as to surround the outlet of the airtight member. A wet tissue dispensing container is disclosed in which a wall is formed and the tip of the upstanding wall of the lid when closed is in contact with the inner ridge line or the inner inclined surface and the outer ridge line or the outer inclined surface of the convex part.

Patent No. 5230776 gazette

In Patent Document 1, the tip of the upstanding wall formed on the lid has a simple structure in which the inner ridge line or inner inclined surface of the convex part disposed on the container body and the outer ridge line or outer inclined surface are in contact with each other. It is disclosed that airtightness can be reliably ensured. However, in general, parts such as a container body and an airtight member constituting the wet tissue dispensing container are manufactured by injection molding or the like so as to be within a predetermined dimensional tolerance. For this reason, when assembling the wet tissue dispensing container by combining the respective parts, it is rare that the position of the annular standing wall and the position of the convex portion completely coincide, and the convex portion relative to the position of the annular standing wall There are many cases where the position of is shifted. When such positional deviation between the annular standing wall and the convex portion occurs, a gap is opened between the standing wall and the convex portion, and the airtightness of the wet tissue dispensing container is impaired.

An object of the present invention is to provide a wet tissue dispensing container in which the airtightness is not lost.

The present invention relates to a wet tissue dispensing container including a container body having a discharge opening on the upper surface, and an upper lid attached to the upper surface of the container body via a hinge and capable of opening and closing the discharge opening.

In the dispensing container of the present invention, the container body is provided with a seal member covering at least a part of the removal opening, and the seal member has a ridge annularly surrounding the removal opening, and the surface of the upper lid facing the container body And a projection which is annularly surrounding the ejection opening and capable of being in contact with the ridge, and is characterized in that the inside of the ridge is hollow. In the dispensing container of the present invention, since the inside of the raised portion provided in the sealing member is hollow, when the raised portion formed on the upper lid comes in contact with the raised portion, the raised portion can be easily made regardless of the contact position of the raised portion. By deformation, the airtightness of the wet tissue dispensing container is secured.

In the invention according to one embodiment, a close contact area in contact with the main body of the container and a conductive area away from the main body of the container are disposed on the surface of the seal member facing the main body of the container. Between the cavity and the outer peripheral edge of the seal member to allow the cavity to communicate with the atmosphere. Since the hollow portion in the raised portion communicates with the outside air in this manner, air can escape from the open air from the hollow portion in the raised portion when the protrusion of the upper lid contacts the raised portion, and the raised portion can be made easier. By deformation, the airtightness of the wet tissue dispensing container is secured. The external air referred to in the present invention is surrounded by the container body and the upper lid when the upper lid is closed, but also includes a space communicating with the outside of the wet tissue dispensing container through the gap in the hinge portion or the like.

In the invention which concerns on one Embodiment, a seal member has the to-be-contacted surface which a projection part contacts in the upper part of a protruding part, and the shape of a to-be-contacted surface is either a flat surface and concave surface. Thus, when the shape of the surface to be contacted is flat or concave, the projection can be reliably brought into contact with the surface to be contacted.

In the invention which concerns on one Embodiment, the width | variety of the to-be-contacted surface of a protrusion is larger than the width | variety of the front-end | tip part of the protrusion which contacts a protrusion. As described above, since the width of the contact surface of the protrusion is larger than the width of the tip of the protrusion contacting the protrusion, the protrusion can be displaced even when the position of the protrusion with respect to the protrusion is deviated from the predetermined position. The projections can be reliably brought into contact with each other.

In the invention according to one embodiment, the opening reinforcing member is fixed on the back side of the surface of the sealing member facing the container body, the opening reinforcing member is disposed between the raised portion and the outlet opening, and the adhesion region of the sealing member is , Between the container body and the opening reinforcing member. Thus, by tightly holding the close contact area of the seal member between the container main body and the opening reinforcing member, the close contact area of the seal member is reliably brought into close contact with the main body of the container to ensure the airtightness of the wet tissue dispensing container. be able to.

The present invention provides a wet tissue dispensing container without loss of air tightness.

The top view of the dispensing container which removed the upper lid. FIG. 5 is a cross-sectional view taken along line VV of FIG. 4. Explanatory drawing of operation | movement of a push lock open mechanism.

The following embodiment relates to a wet tissue dispensing container (hereinafter referred to as a dispensing container) shown in the attached drawings, and includes not only the essential constitution of the invention but also selective and preferable constitutions. Hereinafter, the dispensing container of the present invention will be described with reference to the attached drawings.

As shown in FIGS. 1 to 3, the dispensing container 1 is attached to a container main body 15 having a discharge opening 13 on the upper surface 11 and the upper surface 11 of the container main body 15 via a hinge 51 to open and close the discharge opening 13. A possible top cover 12 and a bottom cover 52 closing the bottom of the container body 15 are provided. The container body 15 of the present embodiment has an upper surface recess 18 which is recessed from the upper surface 11 and the bottom surface 19 is flat, and the takeout opening 13 is formed in the upper surface recess 18. When the upper lid 12 is closed, the upper surface recess 18 is covered with the upper lid 12. In addition, a push lock and open mechanism 31 capable of engaging and disengaging the upper lid 12 with respect to the container main body 15 by pushing the upper lid 12 in the tip region of the upper lid 12 opposite to the hinge portion 51 across the extraction opening 13 in the upper lid 12. Is arranged. In the vicinity of the hinge portion 51 between the container main body 15 and the upper lid 12, an elastic member 53 which biases the upper lid 12 in the opening direction is disposed. The wet tissue 2 is stored in a storage space formed by the container body 15 and the bottom cover 52 and is taken out from the removal opening 13. In addition, in FIG. 3, a part of illustration of the open upper lid 12 is omitted.

As shown in FIGS. 4 and 5, the container body 15 further includes a seal member 21 that covers at least a part of the removal opening 13. The seal member 21 is attached to the bottom surface 19 of the upper surface recess 18. The seal member 21 is a flexible member formed of an elastic material such as silicone rubber and a thermoplastic elastomer. The seal member 21 has an outer peripheral edge 26, a conduction region 24 adjacent to the outer peripheral edge 26, a raised portion 22 located inside the outer peripheral edge 26 and the conductive region 24, and an adhesion region 23 located inside the raised portion 22. And an air gap 28 located inside the close contact area 23. The gaps 28 are disposed at positions overlapping the removal opening 13, and the wet tissues 2 are removed one by one through the gaps 28. The ridges 22 and the close contact area 23 of the seal member 21 are areas that annularly surround the outlet opening 13 in a plan view of the dispensing container 1 (see FIG. 4). In the present embodiment, the conductive region 24 is a region which is located outside the ridge 22 and surrounds the ridge 22 annularly and continuously, but as described later, they should be arranged along the outer peripheral edge 26 at intervals. You can also. FIG. 4 is a plan view of the dispensing container 1 with the upper lid 12 removed.

The inside of the raised portion 22 of the seal member 21 is hollow. More specifically, the hollow portion 25 is formed inside the raised portion 22, and a part of the hollow portion 25 is exposed on the surface of the sealing member 21 opposite to the upper surface concave portion 18 of the container body 15. It is in communication. On the other hand, on the surface of the upper lid 12 opposed to the container main body 15, a protrusion 17 which contacts the raised portion 22 when the upper lid 12 is closed and which annularly surrounds the ejection opening 13 in a plan view is erected. Thus, by making the inside of the raised portion 22 of the sealing member 21 hollow, when the raised portion 17 formed on the upper lid 12 contacts the raised portion 22, the raised portion 22 does not depend on the contact position of the raised portion 17. As it is easily deformed so as to be crushed, the projection 17 closely adheres to the projection 22 without a gap, and the airtightness of the dispensing container 1 can be secured.

An adhesion area 23 capable of coming into contact with the bottom surface 19 of the upper surface recess 18 and a conduction area 24 separated from the bottom surface 19 of the upper surface depression 18 are disposed on the surface of the sealing member 21 facing the upper surface recess 18 of the container body 15 There is. The adhesion area 23 is an area that bulges from the seal member 21 toward the bottom surface 19 and annularly surrounds the ejection opening 13 in a plan view of the dispensing container 1. In the conduction region 24, a gap is provided between the seal member 21 and the bottom surface 19 of the upper surface recess 18. In the present embodiment, by fixing the seal member 21 to the outer peripheral reinforcing member 65 described later, the gap between the protruding portion 22 and the outer peripheral edge 26 of the seal member 21 is separated from the bottom surface 19 of the upper surface recess 18 to make a gap. It is like that. The conduction region 24 extends between the cavity 25 located in the ridge 22 and the outer peripheral edge 26 of the seal member 21 to allow the cavity 25 to communicate with the outside air. By connecting the hollow portion 25 in the protruding portion 22 to the outside air in this manner, air can easily escape from the hollow portion 25 in the protruding portion 22 when the protrusion 17 of the upper lid 12 contacts the protruding portion 22. Therefore, as a result of the protrusion 22 being more easily deformed, the protrusion 17 is more closely attached to the protrusion 22 and the airtightness of the dispensing container 1 is improved. In addition, when the upper lid 12 is closed, the protrusion 17 contacts the raised portion 22 and compresses the air in the hollow portion 25, whereby the upper lid 12 may be pushed back by the raised portion 22 and the upper lid 12 may not be easily closed. . However, if the conduction region 24 is provided, compression of air in the hollow portion 25 does not occur, so that it is possible to prevent the upper lid 12 from becoming difficult to close.

The conduction region 24 of the present embodiment is disposed in the entire region between the outer peripheral edge 26 of the seal member 21 and the hollow portion 25 in the raised portion 22. However, it is sufficient for the conduction region 24 to communicate the cavity 25 in the raised portion 22 with the outer peripheral edge 26. For example, the conduction region 24 is a plurality of strip-shaped regions extending between the hollow portion 25 and the outer peripheral edge 26. In the region between the plurality of strip-like regions, the sealing member 21 and the upper surface recess 18 of the container main body 15 The bottom surface 19 may be in contact with the structure. Further, the ridge 22 and the upper surface recess 18 are disposed by arranging the ridge 22 along the outer peripheral edge 26 of the seal member 21 and cutting out a part or all of the lower end edge portion of the ridge 22 located at the outer peripheral edge 26. A gap may be provided between the lower surface 19 and the bottom surface 19, and this gap may be used as the conduction region 24.

The upper portion of the raised portion 22 of the seal member 21 is provided with a contact surface 27 with which the protrusion 17 formed on the upper lid 12 contacts. The shape of the contact surface 27 is preferably either a flat surface or a concave surface. By making the shape of the contact surface 27 flat or concave, the projection 17 can be reliably contacted by the contact surface 27 regardless of the contact position of the projection 17. Further, in the case where the contact surface 27 has a flat surface, if the wall-like projections are erected on both ends of the flat surface, the projection 17 is flat even if the contact position of the projection 17 is largely deviated. Can be prevented from falling out of place. Further, the width of the contact surface 27 of the raised portion 22 can be made larger than the width of the tip portion 17a of the protruding portion 17 in contact with the raised portion 22 (see FIG. 2). Thus, the projection 17 can be reliably brought into contact with the contact surface 27 of the projection 22. However, the shape of the end portion 17a of the projection 17 is flat, and the width of the end portion 17a of the projection 17 is larger than the width of the contact surface 27 of the projection 22. The case where the cover 27 is in contact with the cover 27 is also included in the scope of the present invention.

As shown in FIGS. 2 and 3, the dispensing container 1 of the present embodiment includes an opening reinforcing member 61 fixed to the back side of the surface of the sealing member 21 opposite to the bottom surface 19 of the top surface recess 18 of the container body 15. . The opening reinforcing member 61 is disposed between the protruding portion 22 and the outlet opening 13 in a plan view of the dispensing container 1, and the close contact area 23 of the sealing member 21 corresponds to the bottom surface 19 of the upper surface recess 18 of the container body 15. And the opening reinforcing member 61. The opening reinforcing member 61 is formed of a material that is less susceptible to elastic deformation than the sealing member 21 and can be formed of, for example, a thermoplastic resin such as polypropylene, polystyrene, or an ABS resin. As described above, since the opening reinforcing member 61 is less elastically deformed than the sealing member 21, the adhesion region 23 of the sealing member 21 is surely in close contact with the bottom surface 19 of the upper surface recess 18. Here, as described above, the conductive area 24 is disposed between the ridge 22 and the outer peripheral edge 26 of the seal member 21 to connect the hollow 25 in the ridge 22 to the outside air. As in the present embodiment, the adhesion area 23 is disposed between the protruding portion 22 and the extraction opening 13, and the adhesion area 23 is brought into close contact with the bottom surface 19 of the upper surface recess 18 by the opening reinforcing member 61. Are isolated from the cavity 25 in the ridge 22. Therefore, the release opening 13 is prevented from communicating with the outside air through the hollow portion 25 and the conduction region 24 in the raised portion 22, so that the airtightness of the dispensing container 1 is secured (see FIGS. 2 and 3).

In the embodiment shown in FIGS. 2 to 4, the bottom surface 19 of the upper surface recess 18 facing the close contact area 23 of the seal member 21 in the container body 15 has a convex shape annularly surrounding the outlet opening 13 in plan view of the dispensing container 1 The section 16 is set up. The close contact area 23 of the seal member 21 is a tip end area of the wall-like protrusion 29 extending from the seal member 21 toward the bottom surface 19 of the upper surface recess 18. The base end portion 29 a of the projecting portion 29 formed on the seal member 21 is disposed at a position overlapping the opening reinforcing member 61, and the adhesion region 23 stands on the opening reinforcing member 61 and the upper surface recess 18 of the container main body 15. It is sandwiched between the provided convex portion 16. The embodiment of the present invention is not limited to the illustrated example, and the adhesion of the sealing member 21 is provided on the condition that the open port 13 can be prevented from communicating with the outside air through the hollow portion 25 and the conduction region 24 in the raised portion 22. The structure of the region 23 and the structure of the portion of the container body 15 facing the contact region 23 of the seal member 21 can be variously changed. For example, the close contact area 23 of the seal member 21 may be formed to be hemispherically raised from the seal member, and the portion of the container main body 15 opposed to the close contact area 23 may be flat.

The opening reinforcing member 61 has an auxiliary opening 62 which has an opening area larger than the extraction opening 13 and has a shape that does not block the extraction opening 13. The auxiliary opening 62 overlaps the ejection opening 13 so as not to close the ejection opening 13. Inside the auxiliary opening 62, the sealing member 21 extends so as to cover at least a part of the removal opening 13. In a portion where the seal member 21 extends to the removal opening 13, a gap 28 for removing the wet tissue 2 is disposed. The outer shape of the opening reinforcing member 61 is not particularly limited, but it is preferable that the shape be inscribed in the annular raised portion 22 in a plan view of the sealing member 21.

In the present embodiment, an outer peripheral reinforcing member 65 is attached at least in a region from the raised portion 22 of the sealing member 21 to the outer peripheral edge 26. The outer periphery reinforcing member 65 is formed of the same material as the opening reinforcing member 61 and is fixed to the seal member 21. Further, as shown in FIGS. 3 to 5, the outer peripheral reinforcing member 65 includes an extending portion 66 extending outward from the outer peripheral edge 26 of the sealing member 21. In the extension portion 66, a mounting hole 68 for inserting the mounting pin 14 erected on the upper surface concave portion 18 of the container main body 15 is formed. When the outer peripheral reinforcing member 65 is fixed to the upper surface recess 18 of the container main body 15 together with the seal member 21 by the mounting pin 14, a gap is left between the outer peripheral reinforcing member 65 and the sealing member 21 and the bottom surface 19 of the upper surface recess 18 A conduction region 24 for communicating the hollow portion 25 in the portion 22 to the outside air is formed (see FIG. 5).

As shown in FIG. 3, in the present embodiment, the extension part 66 located in the vicinity of the hinge part 51 is used as a means for fixing the elastic member 53, and further, the upper lid 12 in plan view of the dispensing container 1. The extension part 66 located in the front end area | region of this is used as a means to slidably hold | maintain the lock tool 32 contained in the push lock open mechanism 31 mentioned later. However, in the present invention, the extension 66 located in the vicinity of the hinge 51 and the extension 66 located in the end region of the upper lid 12 are not essential. For example, the extension 66 located in the vicinity of the hinge 51 and the extension 66 located in the end region of the upper lid 12 can be replaced with a member different from the outer circumferential reinforcing member 65 or omitted.

As a means for fixing the opening reinforcing member 61 and the outer peripheral reinforcing member 65 to the sealing member 21, adhesion may be mentioned. Further, when the opening reinforcing member 61 and the outer peripheral reinforcing member 65 and the seal member 21 are formed in one mold by double molding (also referred to as two-color molding), the opening reinforcing member 61 made of thermoplastic resin and the outer peripheral reinforcing The member 65 and the sealing member 21 made of an elastic material can also be fixed to each other by welding.

Next, with reference to FIGS. 3 and 6, the push lock / open mechanism 31 used in the present embodiment will be described. However, in the present invention, the push lock / open mechanism 31 is not essential, and for example, the open / close mechanism of the upper lid 12 known in the technical field to which the present invention belongs, such as the locking mechanism disclosed in Patent Document 1 can be used.

The push lock and open mechanism 31 includes a lock 33 having a lock projection 34 and a lock 32 that can be engaged with and released from the lock projection 34 of the lock 33. As shown in FIG. 5, in the present embodiment, the locking tool 33 is provided upright on the back side of the front end region of the upper lid 12 opposed to the hinge portion 51 in the direction orthogonal to the hinge axis. Further, the lock 32 is disposed in the container body 15, and when the upper lid 12 is closed, the locking projection 34 of the lock 33 enters the lock 32. The lock 32 is a flat member, and is housed slidably in a direction parallel to the hinge axis in a lock storage chamber 35 formed at a position opposite to the hinge 51 in the container main body 15. . The lock storage chamber 35 includes a through hole 36 into which the locking protrusion 34 of the locking device 33 erected on the upper lid 12 can enter.

As shown in FIG. 6, on the surface of the lock member 32, there are provided an inlet / outlet portion 41 to which the locking projection 34 can enter and exit, an engaging portion 42 to which the locking projection 34 can be engaged, and a locking projection 34. An entry groove 43 for guiding from the inlet / outlet portion 41 to the engaging portion 42 and a withdrawal groove 44 for guiding the locking projection 34 from the engaging portion 42 to the inlet / outlet portion 41 are formed. Each of the entrance groove 43 and the exit groove 44 has

direction reversing parts

45 a and 45 b in which the direction of guiding the locking projection 34 is reversed. In the lock 32, the engaging portion 42 is located between the port 41 and the

direction reversing portions

45 a and 45 b. Further, the inlet / outlet portion 41 formed in the lock member 32 communicates with the through hole 36 of the lock member storage chamber 35.

The depth of the entry groove 43 becomes shallower as it goes from the entrance / exit part 41 toward the direction reversing part 45a, and becomes steeper after passing the direction reversing part 45a. The engagement portion 42 is formed deeper than the entry groove 43. Further, at the boundary between the engaging portion 42 and the withdrawal groove 44, the withdrawal groove 44 is deeper. The depth of the exit groove 44 becomes shallower as it goes from the engaging portion 42 through the direction reversing portion 45 b to the entrance / exit portion 41. In the entrance / exit portion 41, the depth of the entry groove 43 is deeper than the exit groove 44. As described above, since the upper lid 12 is biased in the opening direction, the locking projection 34 entering the entry groove 43 is biased toward the entrance / exit portion 41. Therefore, when the locking projection 34 formed on the upper lid 12 is advanced to the direction reversing portion 45 a of the entering groove 43 of the locking member 32 when the upper lid 12 is pushed and closed, the locking biased toward the entrance / exit portion 41 The projection 34 falls into the engagement portion 42 and comes to rest. Thereby, the upper lid 12 is closed. When the closed upper lid 12 is pushed again, the locking projection 34 is detached from the engaging portion 42, passes through the direction reversing portion 45b, reaches the inlet / outlet portion 41, and further passes through the through hole 36 of the lock storage chamber 35. , The upper lid 12 is opened.

As mentioned above, although this invention was demonstrated based on embodiment, this invention is not limited to these, It can change variously and can implement. For example, the shape of the void portion 28 is not limited to the illustrated example, and may be any shape such as a cruciform cut, a circular or elliptical hole. Although the container main body 15 of this embodiment is formed with the upper surface recess 18 which is recessed from the upper surface 11, the upper lid 12 may be configured to cover the entire upper surface 11 of the container main body 15, and the upper surface recess 18 may be omitted. . Although the case where the seal member 21 is disposed on a plane is described as an example, the seal member 21 can be disposed on a smooth curved surface as long as the airtightness of the seal member 21 is not impaired. The material for producing the dispensing container 1 of the present invention is not particularly limited, and can be appropriately selected from known materials such as thermoplastic resin, metal, thermoplastic elastomer and the like.
