Abstract

PROBLEM TO BE SOLVED: To provide a hinge cap in which a top cover can be kept engaged in a temporary engaging state and can be opened and closed with a small force, thus eliminating the need for closing the top cover completely on a dining table or in other places where the top cover is opened and closed frequently.SOLUTION: A temporary engagement projection is projected in a side opposing a hinge on an inner peripheral surface of a spouting cylinder, and an engagement end part, which forms a seal surface toward the inner peripheral surface of the spouting cylinder when a top cover is closed completely, is provided at an outer peripheral bottom part of a sealed cylinder vertically installed from a top wall inner surface of the top cover. When the top cover is closed temporarily, a lower contact surface of a diameter-reduced protrusion part of the top cover comes in contact with a top part of an annular swollen part of the cap body while being subjected to sliding resistance, and the top part of the engagement end part engages a bottom part of the temporary engagement projection.

Description

  The present invention relates to a hinge cap in which an upper lid is connected to a cap body attached to a container mouth portion via a hinge, and in particular, when a container is used on a table or the like, the cap is not completely closed. The present invention relates to a hinge cap that is engaged and held in a temporarily closed state with a main body so that the upper lid can be easily opened and closed with a small force.

Containers that contain liquid contents such as fluid foods are filled with heated liquid contents for sterilization, and then a hinge cap is plugged into the mouth of the container, and washed from outside the container with a shower. It is produced through a heat treatment process of cooling.
At that time, the air in the hinge cap is heated to increase the internal pressure, and the upper lid may be opened during the production process, causing trouble.

In order to prevent the lid from being opened by such heat treatment, it is only necessary to increase the engagement force by increasing the amount of protrusion between the cap main body and the engagement portion of the upper lid. However, if the engagement force is increased too much, the consumer uses it. It will be difficult to open the top lid.
Therefore, the main lid and the auxiliary projection are provided on the engaging projection of the upper lid, and the upper lid is prevented from opening by the double locking mechanism that the auxiliary projection works when the main projection gets over the engaging projection of the cap body. A hinge cap is conventionally known (see, for example, Patent Document 1).

A pouring cylinder 6 is erected on the inner edge of the base wall 8.
A partition wall 7 that seals the inside of the container is connected to a lower portion of the inner periphery of the dispensing cylinder 6, and the partition wall 7 is defined by a thin weakened portion 17 that opens a dispensing opening that communicates with the interior of the container. A formed removal portion 18 is provided, and a pull ring 19 is erected on the removal portion 18 via a support column.

As shown in FIG. 3A, a temporary engagement protrusion 21 protruding inward is provided on the inner peripheral surface of the dispensing cylinder 6 on the side opposite to the hinge C over a predetermined arc range.
In this embodiment, the circular arc range has a circumferential angle α of about 30 °, but is not limited to 30 ° and can be appropriately determined.
Further, as in the modification shown in FIG. 3B, the temporary engagement protrusions 21 may be provided on both sides of the vicinity of the center serving as the flow path of the content liquid poured out from the container.

A thin inclined fin 22 is provided around the dispensing opening, that is, on the partition wall 7 surrounding the weakened portion 17 to form a wall surface that is inclined inward and protrudes upward.
On the upper surface of the partition wall 7 between the outer wall surface of the inclined fin 22 and the inner peripheral surface of the dispensing tube 6, a liquid recovery inclined surface 23 that is inclined downward toward the inside is formed. Cutout portions 24 that are notched with a predetermined width in the circumferential direction are provided so as to form flow paths that communicate with the liquid recovery inclined surface 23 at a plurality of locations in the circumferential direction.
In the present embodiment, the notch portions 24 are provided at eight locations at equal intervals, but the location and number of the notch portions 24 can be determined as appropriate. However, on the side opposite to the hinge C, a notch 24 is always disposed to form a flow path when the content liquid is poured out from the container.

The upper lid B includes a top wall 30 and an outer peripheral wall 31 suspended from the periphery of the top wall 30, and a hinge C is continuously provided at a predetermined position on the outer peripheral lower end of the outer peripheral wall 31.
On the back surface of the top wall 30, a sealing cylinder 32 fitted into the inner periphery of the extraction cylinder 6 of the cap body A is suspended.
An engagement end portion 33 projecting in an annular shape is provided at the lower end of the outer periphery of the sealing cylinder 32, and a sealing surface can be formed between the inner peripheral surface of the dispensing cylinder 6 to seal the inside of the container. It is like that.
The lower end of the inner periphery of the sealing cylinder 32 is provided with a flange portion 34 projecting obliquely downward over a predetermined arc range centered on the hinge C side, and the tip thereof is provided when the cover is completely closed and temporarily closed. At the time of covering, it extends inward from the tip position of the inclined fin 22 in a plan view.

As shown in FIGS. 2 and 4, a reduced diameter protrusion 35 projecting inward is provided on the inner periphery of the lower end of the outer peripheral wall 31, and the upper portion of the reduced diameter protrusion 35 has a lid when fully closed. An upper engaging surface 35a that engages with the annular bulging portion 14 of the engaging portion 12 is formed, and is further continuous with the diameter-enlarged concave ridge portion 36 into which the annular bulging portion 14 is fitted.
In addition, a lower contact surface 35b that contacts the inclined surface 15 on the upper portion of the annular bulging portion 14 is formed at the lower portion of the reduced diameter projecting ridge portion 35 when temporarily closed, and the inclination is increased toward the lower end of the outer peripheral wall 31. It has a surface.
A knob 37 protrudes on the opposite side of the outer peripheral lower end of the outer peripheral wall 31 from the hinge C.

  The positional relationship between the reduced diameter protrusion 35 of the upper lid B and the annular bulging portion 14 of the cap body A, and the engagement end 33 of the upper cover B and the temporary engagement protrusion 21 of the cap body A is the reduced diameter protrusion. When the lower abutment surface 35b of the abutment 35 abuts against the inclined surface 15 of the annular bulging portion 14 while receiving sliding resistance, the engagement end portion 33 gets over the temporary engagement protrusion 21 and the engagement end portion 33 The upper part is disposed so as to be in a temporarily closed state where the upper part engages with the lower part of the temporary engagement protrusion 21.

Next, usage modes and operational effects of this embodiment will be described.
In order to attach the hinge cap to the container main body D, the upper lid B is closed to obtain a completely closed state as shown in FIG.
When closing the upper lid B, first, the sealing cylinder 32 is inserted into the inner periphery of the pouring cylinder 6, and the engaging end 33 of the sealing cylinder 32 is inserted into the pouring cylinder 6 as shown in FIG. When the temporary engagement protrusion 21 is overcome, the lower contact surface 35 b of the reduced diameter protrusion 35 is in a temporarily closed state in which the lower contact surface 35 b contacts the upper inclined surface 15 of the annular bulging portion 14.
When the upper lid B is further closed by applying a force, as shown in FIG. 4A, the diameter-reduced protrusion 35 gets over the annular bulging portion 14, and the upper engagement surface 35 a is connected to the annular bulging portion 14. Engage with each other to form a sealing surface, and the enlarged diameter recessed groove portion 36 is fitted to the annular bulging portion 14 to be in a completely closed state.
At this time, the engagement end portion 33 of the sealing cylinder 32 is in close contact with the inner peripheral surface of the dispensing cylinder 6 to form a sealing surface.

Next, the mouth portion 1 of the container body D is placed in the annular groove between the inner cylinder 9 and the outer cylinder 10 of the hinge cap that is completely closed, and is pressed from the upper portion of the upper lid B to be plugged.
At the time of stoppering, the engaging ridge 13 of the outer cylinder 10 gets over the annular ridge 3 of the mouth 1 and engages with the mouth 1, and the cap body A is attached to the mouth 1 of the container body D.

When the container is used, a finger is put on the knob 37 of the upper lid B and lifted upward to release the engagement between the reduced diameter protrusion 35 and the annular bulging portion 14. The engagement between the portion 33 and the temporary engagement protrusion 21 is also released, and the upper lid B is opened.
Next, the pull ring 19 is pulled upward, the weakened portion 17 is broken, the removed portion 18 is cut off, and the dispensing opening is opened.
If the container is held and tilted, the content liquid is guided to the dispensing cylinder 6 through the dispensing opening and can be poured out of the container.

After the container is used, the knob 37 of the upper lid B is pushed down to close the container. However, in a container that is heat-treated by heat filling or the like, the relationship between the reduced diameter protrusion 35 and the annular bulging part 14 in the completely closed state is achieved. Since the resultant force is set to be large, a large force is required to completely close the cover, and a large force is also required to open the cover again.
Therefore, when the container is frequently used on a table or the like, when the upper lid B is closed, the engagement end portion 33 of the sealing tube 32 gets over the temporary engagement protrusion 21 of the dispensing tube 6 and the diameter-reduced ridge. When the lower contact surface 35b of the portion 35 contacts the inclined surface 15 at the upper portion of the annular bulging portion 14, the repulsive force due to the engagement between the upper portion of the engagement end portion 33 and the lower portion of the temporary engagement protrusion 21 Since the repulsive force due to the contact between the lower contact surface 35b of the reduced diameter ridge 35 and the inclined surface 15 of the annular bulging portion 14 is balanced and temporarily closed, no further force is applied, It can be placed on the table for the next use.

Since the engagement force between the engagement end portion 33 and the temporary engagement protrusion 21 is set to be considerably smaller than the engagement force between the reduced diameter protrusion 35 and the annular bulging portion 14, a container is frequently used at a table or the like. In this case, if the upper lid B is closed and used in a temporarily closed state, even a weak child or the elderly can easily open and close.
After that, when the product is used at the table and stored in a refrigerator or the like, it is further closed by applying additional force until the diameter-enlarged recess 36 is engaged with the annular bulging portion 14 and moved and stored in a completely closed state. That's fine.

  In addition, when the content liquid is dressing or various kinds of soy sauce or shake, it is used by shaking the container, but in this embodiment, it is inclined inward and protrudes upward around the dispensing opening. Since the inclined fins 22 forming the wall surface are provided, the content liquid that jumps out from the dispensing opening when the container is shaken can be concentrated near the center of the upper lid B by the inclined fins 22, and the content liquid is sealed cylinder Since the sealing part 32 and the extraction cylinder 6 are not covered, leakage of the content liquid can be prevented even in a temporarily closed state where the sealing cylinder 32 and the extraction cylinder 6 are not sealed.

Furthermore, in the present embodiment, a liquid recovery inclined surface 23 that is inclined downward toward the inside is formed on the upper surface of the partition wall 7 between the outer wall surface of the inclined fin 22 and the inner peripheral surface of the dispensing cylinder 6, Since the fins 22 are provided with the notches 24 serving as flow paths communicating with the liquid recovery inclined surface 23 at a plurality of locations in the circumferential direction, the content liquid that has jumped out from the dispensing opening can be efficiently recovered in the container. .
Since the notch 24 is always arranged on the side opposite to the hinge C, the inclined fin 22 does not get in the way when the content liquid is poured out.

When the container is shaken, the liquid adhering to the back surface or the like of the upper lid B may flow down from the hinge C side of the sealing cylinder 32 when tilted when the upper lid B is opened or closed. Since a flange 34 is provided at the lower end of the inner periphery of the flange 34 so as to protrude obliquely downward over a predetermined arc range centered on the hinge C side, when the upper lid B is opened and closed, residual liquid is applied to the flange 34. There is no such thing as getting caught and getting dirty.
Since the tip of the collar portion 34 extends inward from the tip position of the inclined fin 22 in a plan view when fully closed and temporarily closed, the liquid can be quickly collected in the container.

Next, a description will be given of a second embodiment in which the configuration of the notch is changed in accordance with the change in the configuration of the partition wall.
Hereinafter, the same reference numerals are given to the same components as in the first embodiment, and the description will focus on the differences. As shown in FIG. 5, in this embodiment, the partition wall 7 of the container body A is on the hinge C side. The notch portion 24 of the inclined fin 22 is only the notch portion 24a also serving as a liquid discharge passage and the notch portion 24b on the half circumferential surface on the hinge C side. This is different from the first embodiment in that it is not provided on the half circumferential surface opposite to C except for the notch 24a.

  In this embodiment, since the partition wall 7 is inclined downward toward the hinge C side, the content liquid remaining on the liquid recovery inclined surface 23 flows down to the hinge C side according to the inclination. The cut-out portion 24b may be provided at several places or one place on the half-circumferential surface on the hinge C side, and the cut-out portion 24a that also serves as a content liquid discharge channel is provided on the half-circumferential surface opposite to the hinge C. Need only be provided.

  In this way, it is difficult for the liquid to remain on the liquid recovery inclined surface 23 on the side opposite to the hinge C from which the content liquid is poured out, and when the container is tilted to pour out the content liquid, the residual liquid is The hinge C which does not flow out earlier and contaminates the surroundings, and has a large gap between the unsealed sealing cylinder 32 and the dispensing cylinder 6 when the container is shaken in the temporarily closed state. On the opposite side, the content liquid is more difficult to scatter and the liquid leakage from the gap between the sealing cylinder 32 and the dispensing cylinder 6 is further prevented.

Moreover, although it can be said not only in the second embodiment but also in the first embodiment, if the temporary engagement protrusion 21 shown in FIG. Since the protrusion 21 also serves as a breakwater for the content liquid that jumps out from the notch 24a for pouring the content liquid, it is possible to further prevent liquid leakage from the gap between the sealed cylinder 32 and the extraction cylinder 6. .
Other functions and effects are the same as those of the first embodiment.

  Since the hinge cap of the present invention can be easily opened and closed by anyone when used in a temporarily closed state with a weak engagement force, it is large when the lid is closed like a container that has undergone a heat treatment process such as heating and filling. It can be widely used as a container cap that requires the upper lid to be engaged by force, and is particularly suitable for application to a container cap that is frequently opened and closed on a table or the like.
