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.
- 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 .
- 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.
- 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 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.

Abstract
A thin attachment cap capable of simply taking out contents from a container containing drinking water, juice, powder or the like. In the attachment cap (30), by pressing down a pressing part (33) in the direction of an arrow (34) while a lid (31) is closed, the lid (31) rotates in the direction of an arrow (35) and an extraction port (37) is opened. When the pressing part (33) is completely pressed down, the lid (31) stands up approximately at the right angle with respect to a cap base (32). When the lid (31) stands up, the lid (31) is temporarily fixed, and a liquid or the like in the container can be smoothly taken out through the extraction port (37).
Description
- 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.
- It would be very convenient to be able to smoothly take out a liquid or the like from a container containing the liquid or the like by a single handed operation. There have been proposed various cap mechanisms of this kind allowing a lid to be opened by a single push.
- For example, U.S. Pat. No. 5,730,310 discloses a lid opening mechanism in which, particularly in FIG. 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 alid section 12 around abending line 21. According to this mechanism, as illustrated in FIG. 31, it is understood that thelid section 12 rotates around asupport section 24. As thelid section 12 rotates, thebending line 21 gets into a space formed between the pushing operation section 5 and thesupport section 24. In other words, thelid section 12 rotates by leverage using asupport section 24 as the fulcrum. - Alternatively, as illustrated in
FIG. 1A according to the present application, anattachment cap 12 is attached to apaper carton pack 11 to take out juice or the like contained in thepaper carton pack 11. In order to open theattachment cap 12, as illustrated inFIG. 1B , first, thepaper carton pack 11 is held by one hand and alid body 13 of theattachment cap 12 is lifted by the other hand so as to open a pouring opening 15 of acap base 14. Then, juice or the like, which are contents, can be poured into a glass through thepouring opening 15. - According to the above embodiment disclosed in U.S. Pat. No. 5,730,310, 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 thecase 11, it is preferable to provide a small space formed between the pushing operation section 5 and thesupport 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 thelid section 12 becomes larger, the stronger pushing pressure is needed. - Further, the
attachment cap 12 illustrated inFIG. 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 thepaper carton pack 11 through thepouring 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.
- In light of this, the attachment cap according to the present invention 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. In the attachment cap configured in this manner, 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. In a state in which the pouring opening is sealed by the plug section, when the pushing operation section is pushed out into the receiving region, the lid body rotates to release the plug section from the pouring opening.
- Further, 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.

FIG. 2 is a perspective view for schematically describing an operation of opening alid body 22 in a state in which anattachment cap 20 according to the present invention is attached to apaper carton pack 21. In a state in which thelid body 22 is closed, when a pushingoperation section 23 of theattachment cap 20 is pushed down, thelid body 22 rotates in a direction indicated by anarrow 24. As a result, a pouringopening 25 opens and anair vent 26 opens as well. Since theair vent 26 opens, a liquid in thepaper carton pack 21 can be smoothly taken out through the pouringopening 25. -
FIGS. 3A , 3B, and 3C each is a perspective view for schematically describing an operation of anattachment cap 30 according to a first embodiment of the present invention.FIG. 3A is a drawing illustrating a state in which alid body 31 of theattachment cap 30 is closed. In this state, thelid body 31 is folded into acap base 32 and a pouring opening is closed by thelid body 31. As described later, an air vent is also closed by an air vent plug section. - As illustrated in
FIG. 3B , when a pushingoperation section 33 is pushed down in a direction indicated by anarrow 34, thelid body 31 rotates in a direction indicated by anarrow 35. As a result, thelid body 31 is disengaged from acylindrical wall 36 and a pouringopening 37 opens. At the same time, anair vent 38 is released from an airvent plug section 39. When the pushingoperation section 33 is completely pushed down, as illustrated inFIG. 3C , thelid body 31 stands up substantially at a right angle with respect to thecap base 32. When thelid body 31 stands up, thelid body 31 is located on anupstanding section 40 of thecap base 32 and temporarily fixed thereto (described later). Therefore, a liquid in the container can be smoothly taken out through the pouringopening 37. - Next, the structure of the attachment cap according to the present invention will be described.
FIGS. 4A , 4B, and 4C are a plan view, a side view, and a bottom view of anattachment cap 41 according to an embodiment of the present invention at the time of its formation respectively.FIG. 5 is a sectional view along line A-A ofFIG. 4A . Hereinafter, by referring to these figures, the structure of theattachment cap 41 will be described. - The
attachment cap 41 includes acap base 42, ahinge section 43, and alid body 44, which are integrally formed using a synthetic resin such as polypropylene. As illustrated inFIG. 4A , thecap base 42 has a pouringopening 45 substantially at its center and acylindrical wall 46 at its surrounding. It is desirable to form thecylindrical wall 46 into a shape allowing the contents to be easily taken out from the container. Thecap base 42 further includes a receivingregion 47 in a position adjacent to thehinge section 43. The region forms a region lower than its surrounding. As described later, the receivingregion 47 forms a space for receiving a pushingoperation section 48 when the pushingoperation section 48 is pushed down. Anair vent 49 is formed between thecylindrical wall 46 and the receivingregion 47. Theair vent 49 may pass air when a liquid or the like inside the container is taken out. Therefore, theair vent 49 may have a small diameter and may be formed in any position of thecap base 42. - The
hinge section 43 includes the pushingoperation section 48 and acorrection arm section 50 formed on both sides of the pushingoperation section 48 and parallel to the pushingoperation section 48, each formed between thecap base 42 and thelid body 44. Agap 51 is provided between the pushingoperation section 48 and thecorrection arm section 50. The pushingoperation section 48 and thecorrection arm section 50 constitute a hinge mechanism. Thehinge section 43 has afirst bending section 52 and asecond bending section 53 interposed between thecap base 42 and thehinge section 43. Thehinge section 43 can rotate with the first andsecond bending sections - The

InFIG. 7 , a receivingregion 58 is formed between the pushingoperation section 48 and thecap base 42. When the pushingoperation section 48 is pushed down, the pushingoperation section 48 moves inside the receivingregion 58 as described later. -
FIGS. 8A , 8B, 8C, and 8D each are a sectional view for describing the operation that from a state in which theattachment cap 41 attached to acontainer 80 such as a paper carton pack closes its lid, thelid body 44 rotates until the pouringopening 45 is completely opened.FIG. 8A illustrates a state in which theplug section 56 of theattachment cap 41 is fit to the pouringopening 45 to close the lid. In this state, as illustrated inFIG. 8B , a pushing force is applied to the pushingoperation section 48 in a direction indicated by anarrow 81, the bendingsection 53 slightly moves in a direction indicated by anarrow 82 and the pushingoperation section 48 sinks into the receivingregion 58. As a result, theplug section 56 and the airvent plug section 57 move upward from the pouringopening 45 and theair vent 49 respectively and thelid body 44 slightly advances in a direction indicated by anarrow 83 to disengage ahook section 84. - In a state in which the
hook section 84 is disengaged, when a pushing force further continues to be applied to the pushingoperation section 48, the pushingoperation section 48 further sinks into the receiving region 88 as illustrated inFIG. 8C . However, thecorrection arm section 50 prevents thelid body 44 from advancing and instead of advancing, thelid body 44 rotates in a direction indicated by anarrow 85 with thebending section 54 as its axis. When the pushingoperation section 48 is further pushed down, thelid body 44 further continues rotating, and thelid body 44 reaches a substantially upstanding state as illustrated inFIG. 8D . In this state, thelid body 44 is placed on theupstanding section 40 and the upstanding state is maintained. -
FIG. 9 is a sectional view for describing a state in which thelid body 44 is maintained in a state in which the pushingoperation section 48 is pushed down into the receivingregion 58 and thelid body 44 completely stands up. When the pushingoperation section 48 is pushed down into the receivingregion 58, theupstanding section 40 prevents the pushingoperation section 48 from laterally moving and the tensile force of thecorrection arm section 50 causes thelid body 44 to rotate and finally reach a completely upstanding state. When the pushingoperation section 48 is pushed down into the receivingregion 58 by a pushing operation, anend section 59 of thebending section 54 on the pushingoperation section 58 side contacts a wedge-shaped upstanding side surface 60 from abottom section 47 and anend section 61 on thelid body 44 side is located on an upper surface of theupstanding section 40 of thecap base 32. In this state, the lateral and upward movements of thelid body 44 are restricted and thelid body 44 maintains the state of standing up on the upper surface of theupstanding section 40 of thecap base 32. As a result, in a state in which the pushingoperation section 48 is press-contacted to theupstanding section 40, thelid body 44 adjacently connected to the pushingoperation section 48 is held standing up. -
FIG. 10 is a sectional view along line C-C ofFIG. 6A . When theattachment cap 41 is closed, eachcorrection arm section 50 placed side by side to the pushingoperation section 48 is located on aledge section 62 formed on thecap base 32. As illustrated in the figure, anangle 63 contacting thecap base 32 of thecorrection arm section 50 is formed into an acute angle slightly less than 90 degrees. When thelid body 44 rotates in a state in which the pushingoperation section 48 is pushed down into the receivingregion 58, thecorrection arm section 50 formed (into a wedge-shape) in this manner can prevent thecorrection arm section 50 from lifting upward from theledge section 62. Thus, thelid body 44 can smoothly rotate. - Thus, 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. Further, 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. Furthermore, 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.
-
FIG. 11 is a plan view of anattachment cap 100 according to a second embodiment of the present invention at the time of its formation.FIG. 12 is a sectional view along line D-D ofFIG. 11 . Theattachment cap 100 according to the second embodiment has the same structure as theattachment cap 41 according to the first embodiment except the shapes of a pouringopening 101 and aplug section 102. The pouringopening 101 does not have a cylindrical wall such as the one in the first embodiment and is formed to be tightly fit to theplug section 102 for sealing. -
FIG. 13 is a plan view of a state of theattachment cap 100 with its lid folded according to the second embodiment of the present invention.FIG. 14 is a sectional view along line E-E ofFIG. 13 . As understood from the sectional view ofFIG. 14 and the side view ofFIG. 15 , the attachment cap of the second embodiment does not have a cylindrical wall around the pouringopening 101, and thus theattachment cap 100 can be formed thinner than theattachment 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.
