Definitions

  • the present invention relates to an attachment cap attached to a container containing a liquid or the like, and more particularly to an attachment cap allowing its lid to be opened by a single push.
  • U.S. Patent No. 5730310 discloses a lid opening mechanism in which, particularly in Figure 30, a pushing operation section 5 is formed on a side surface of a case 11 and the pushing operation section 5 is pushed from a lateral direction thereof to rotate a lid section 12 around a bending line 21.
  • this mechanism as illustrated in Figure 31, it is understood that the lid section 12 rotates around a support section 24.
  • the bending line 21 gets into a space formed between the pushing operation section 5 and the support section 24.
  • the lid section 12 rotates by leverage using a support section 24 as the fulcrum.
  • an attachment cap 12 is attached to a paper carton pack 11 to take out juice or the like contained in the paper carton pack 11.
  • the paper carton pack 11 is held by one hand and a lid body 13 of the attachment cap 12 is lifted by the other hand so as to open a pouring opening 15 of a cap base 14. Then, juice or the like, which are contents, can be poured into a glass through the pouring opening 15.
  • the pushing operation section 5 is pushed by a finger and thus in order to improve the operability, the pushing operation section 5 needs to have a wide area to some extent. This imposes a limitation that the case 11 cannot be very thin. Further, in order to increase the volume of the case 11, it is preferable to provide a small space formed between the pushing operation section 5 and the support section 24. However, the smaller the space, the smaller the lever ratio (a ratio of the distance from a fulcrum point to a force applied point divided by the distance (corresponding to the length of the lid section 12) from the fulcrum point to an operating point). Therefore, as the lid section 12 becomes larger, the stronger pushing pressure is needed.
  • attachment cap 12 illustrated in Figure 1A involves the inconvenience that both hands are required to open it. Furthermore, when a liquid is to be taken out, air will flow back inside the paper carton pack 11 through the pouring opening 15, and thus involves the inconvenience of preventing the liquid from being smoothly taken out.
  • the present invention has been made to solve the above problems and provides an attachment cap allowing contents such as a liquid to be smoothly taken out from a container. More specifically, the present invention provides a cap mechanism which allows its lid to be opened by a single push as well as a further thinner attachment cap which allows its lid to be opened by a small force.
  • the attachment cap includes a cap base, a hinge section adjacently connected to the cap base, and a lid body adjacently connected to the hinge section.
  • the cap base has a pouring opening for taking out contents.
  • the hinge section includes a pushing operation section rotatably connected adjacently to one end of the cap base and a correction arm section formed parallel to and spaced apart from the pushing operation section.
  • the lid body is rotatably connected adjacently to the other end of the pushing operation section and the correction arm section and has a plug section for sealing the pouring opening.
  • the cap base has a receiving region capable of receiving the pushing operation section on an upper surface of the cap base facing an attachment surface of the cap base, and a bottom surface of the receiving region is formed lower than the surface on which the correction arm section abuts against the upper surface.
  • the attachment cap according to the present invention includes not only the above configuration but also an air vent separately from the pouring opening provided on the cap base, in which the lid body includes a plug section and an air vent plug section fit to the pouring opening and the air vent respectively.
  • the present invention can form a shallow region for operating the pushing operation section and thus can provide a thin attachment cap allowing its lid to be opened by a single push. Further, the pushing operation section can be pushed from an upper portion of the attachment cap and thus a relatively strong force can be applied to the pushing operation section. This allows the lid body to be sufficiently rotated. Furthermore, the attachment cap according to the present invention has an air vent and thus allows contents in a container to be smoothly taken out.
  • an attachment cap attached to a paper carton pack will be described based on the drawings.
  • the present attachment cap can be formed by injection molding using polypropylene, but may be formed integrally with a container thereof. Further, the following description is based on the assumption that the present attachment cap is attached to a paper carton pack, but it may be attached to a container other than the paper carton pack such as a synthetic resin carton pack. Furthermore, the illustrated attachment cap is simplified in detail for ease of description and it should be noted that the size of the attachment cap is different from that of an actual attachment cap.
  • the attachment cap may be attached to a container containing powder or particles.
  • the attachment cap may have one pouring opening or a plurality of pouring openings.
  • FIG. 2 is a perspective view for schematically describing an operation of opening a lid body 22 in a state in which an attachment cap 20 according to the present invention is attached to a paper carton pack 21.
  • the lid body 22 In a state in which the lid body 22 is closed, when a pushing operation section 23 of the attachment cap 20 is pushed down, the lid body 22 rotates in a direction indicated by an arrow 24. As a result, a pouring opening 25 opens and an air vent 26 opens as well. Since the air vent 26 opens, a liquid in the paper carton pack 21 can be smoothly taken out through the pouring opening 25.
  • Figures 3A, 3B , and 3C each is a perspective view for schematically describing an operation of an attachment cap 30 according to a first embodiment of the present invention.
  • Figure 3A is a drawing illustrating a state in which a lid body 31 of the attachment cap 30 is closed. In this state, the lid body 31 is folded into a cap base 32 and a pouring opening is closed by the lid body 31. As described later, an air vent is also closed by an air vent plug section.
  • Figures 4A, 4B, and 4C are a plan view, a side view, and a bottom view of an attachment cap 41 according to an embodiment of the present invention at the time of its formation respectively.
  • Figure 5 is a sectional view along line A-A of Figure 4A .
  • the structure of the attachment cap 41 will be described.
  • the attachment cap 41 includes a cap base 42, a hinge section 43, and a lid body 44, which are integrally formed using a synthetic resin such as polypropylene.
  • the cap base 42 has a pouring opening 45 substantially at its center and a cylindrical wall 46 at its surrounding. It is desirable to form the cylindrical wall 46 into a shape allowing the contents to be easily taken out from the container.
  • the cap base 42 further includes a receiving region 47 in a position adjacent to the hinge section 43. The region forms a region lower than its surrounding. As described later, the receiving region 47 forms a space for receiving a pushing operation section 48 when the pushing operation section 48 is pushed down.
  • An air vent 49 is formed between the cylindrical wall 46 and the receiving region 47. The air vent 49 may pass air when a liquid or the like inside the container is taken out. Therefore, the air vent 49 may have a small diameter and may be formed in any position of the cap base 42.
  • the hinge section 43 includes the pushing operation section 48 and a correction arm section 50 formed on both sides of the pushing operation section 48 and parallel to the pushing operation section 48, each formed between the cap base 42 and the lid body 44.
  • a gap 51 is provided between the pushing operation section 48 and the correction arm section 50.
  • the pushing operation section 48 and the correction arm section 50 constitute a hinge mechanism.
  • the hinge section 43 has a first bending section 52 and a second bending section 53 interposed between the cap base 42 and the hinge section 43. The hinge section 43 can rotate with the first and second bending sections 52 and 53 as its axis.
  • the lid body 44 is formed to be adjacently connected to the hinge section 43.
  • the lid body 44 is coupled to the pushing operation section 48 through a third bending section 54 as well as to the correction arm section 50 through a fourth bending section 55.
  • a plug section 56 is formed substantially at the center of the lid body 44 so as to be able to fit to the pouring opening 45 provided in the cap base 42 and seal the pouring opening 45.
  • a protrusion shaped air vent plug section 57 is provided between the pushing operation section 48 and the plug section 56.
  • the lid body 44 rotates with the third bending section 54 and the fourth bending section 55 as its axis.
  • Figures 6A, 6B, and 6C are a plan view, a side view, and a bottom view of the attachment cap 41 with its lid closed according to an embodiment of the present invention respectively.
  • Figure 7 is a sectional view along line B-B of Figure 6A .
  • the attachment cap 41 illustrated in Figure 6A is in a state in which the hinge section 43 of the attachment cap 41 in Figure 4A rotates with the first and second bending sections 52 and 53 as its axis; and the plug section 56 and the air vent plug section 57 of the lid body 44 are fit to the pouring opening 45 and the air vent 49 respectively.
  • a receiving region 58 is formed between the pushing operation section 48 and the cap base 42. When the pushing operation section 48 is pushed down, the pushing operation section 48 moves inside the receiving region 58 as described later.
  • Figures 8A, 8B, 8C, and 8D each are a sectional view for describing the operation that from a state in which the attachment cap 41 attached to a container 80 such as a paper carton pack closes its lid, the lid body 44 rotates until the pouring opening 45 is completely opened.
  • Figure 8A illustrates a state in which the plug section 56 of the attachment cap 41 is fit to the pouring opening 45 to close the lid.
  • a pushing force is applied to the pushing operation section 48 in a direction indicated by an arrow 81
  • the bending section 53 slightly moves in a direction indicated by an arrow 82
  • the pushing operation section 48 sinks into the receiving region 58.
  • the plug section 56 and the air vent plug section 57 move upward from the pouring opening 45 and the air vent 49 respectively and the lid body 44 slightly advances in a direction indicated by an arrow 83 to disengage a hook section 84.
  • Figure 9 is a sectional view for describing a state in which the lid body 44 is maintained in a state in which the pushing operation section 48 is pushed down into the receiving region 58 and the lid body 44 completely stands up.
  • the upstanding section 40 prevents the pushing operation section 48 from laterally moving and the tensile force of the correction arm section 50 causes the lid body 44 to rotate and finally reach a completely upstanding state.
  • FIG 10 is a sectional view along line C-C of Figure 6A .
  • each correction arm section 50 placed side by side to the pushing operation section 48 is located on a ledge section 62 formed on the cap base 32.
  • an angle 63 contacting the cap base 32 of the correction arm section 50 is formed into an acute angle slightly less than 90 degrees.
  • the attachment cap according to the first embodiment allows the pouring opening to be opened simply by pushing the pushing operation section of the attachment cap by a single push and the contents in the paper carton pack to be easily poured out.
  • the receiving region into which the pushing operation section is pushed down can be formed shallow, and thus the attachment cap can be formed thin and does not require a large space on the upper portion of the paper carton pack to be attached thereto.
  • a cylindrical wall is provided around the pouring opening, and thus the contents in the paper carton pack can be smoothly guided in a specific direction by designing the cylindrical wall into a desired shape.
  • Figure 11 is a plan view of an attachment cap 100 according to a second embodiment of the present invention at the time of its formation.
  • Figure 12 is a sectional view along line D-D of Figure 11 .
  • the attachment cap 100 according to the second embodiment has the same structure as the attachment cap 41 according to the first embodiment except the shapes of a pouring opening 101 and a plug section 102.
  • the pouring opening 101 does not have a cylindrical wall such as the one in the first embodiment and is formed to be tightly fit to the plug section 102 for sealing.
  • Figure 13 is a plan view of a state of the attachment cap 100 with its lid folded according to the second embodiment of the present invention.
  • Figure 14 is a sectional view along line E-E of Figure 13 .
  • the attachment cap of the second embodiment does not have a cylindrical wall around the pouring opening 101, and thus the attachment cap 100 can be formed thinner than the attachment cap 41 of the first embodiment.
  • Attachment of the attachment cap according to the present invention to a container containing drinking water, juice, or the like allows the content to be poured out by single push. Further, a thin attachment cap can be formed and thus is convenient for storing, transporting, and using the container to which the attachment cap is attached. Furthermore, the attachment cap according to the present invention can be used for a container containing powder or particles, and can be formed to have a plurality of pouring openings. It should be understood that all of the above configurations should be included in the claims according to the present invention.
