For conventional-out with opening feature container as described above, has been described in the cited document 1 described above, for attaching waterproof paper on the inner side of the cover plate, the outer peripheral wall of the cover plate "double However, in such cases, when the contents are drunk, the contents accumulate on the double wall and cannot be completely removed, especially if the liquid contains solids. In the case of a thing, only a liquid is discharged | emitted out of a container and there exists a problem that a solid substance remains in a container.

  Moreover, in what was described in the above cited reference 2, as a working example of the “cutting blade support” that is displaced around the rotation axis of the hinge, the finger is pushed down with a finger. In such a case, although the non-slip unevenness is provided on the pressing surface of the cutting blade support, the finger is pushed into the container by pressing this part downward, so that the finger may be immersed in the liquid of the contents On the other hand, as another embodiment, there is a pick-up portion extending backward, but in such a case, the pick-up portion stands upright above the opening after opening. Therefore, the picking portion becomes an obstacle when the opening is used as a drinking mouth.

  Furthermore, in what is described in the above cited reference 3, with respect to a “lid opening piercing tool” in which a pressing plate is connected to the supporting plate via a hinge, the portion excluding the supporting plate is rotated downward. In such a case, although the inclination of the pressing plate with respect to the support plate is fixed at a predetermined angle, the finger is immersed in the liquid of the contents as in the case of one embodiment of the cited document 2. There is a risk that. In addition, since most of the inside of the overcap is pushed into the container, there is a risk that the contents may be spilled at the time of opening, and the appearance in the opened state is not good.

  An object of the present invention is to solve the above-described problems. Specifically, with regard to an overcap-shaped opening member mounted on a container sealed with a lid, a finger is placed in the container. It can be opened without plunging or causing liquid splashing, and the contents can be taken out without being disturbed by the opening member, and the appearance in the opened state is not problematic. It is a problem to make it.

  In order to solve the above-described problems, the present invention provides a container main body that contains contents, a sheet-like lid member that seals the opening end of the container main body, and an overcap-like member that breaks and opens the lid member. Opening member consisting of an opening member, with an outer peripheral wall located above the open end of the container body and a top plate located above the lid, which are integrally formed and hinged to the top plate In the container with an opening function in which a push-in portion is formed so as to be pivotable downward via a portion, and a blade portion for breaking the lid member is formed so as to protrude downward from an outer edge of the push-in portion. A push operation plate extending upward in a direction substantially orthogonal to the upper surface of the push portion is integrally formed in the vicinity of the hinge connection portion at the push portion, and the hinge connection portion is used as a fulcrum by pushing the push operation plate sideways. Push part downward The outlet of the contents is formed between the pushing operation plate and the opening end of the container body in a state where the lid is broken and opened by the blade portion. It is.

According to the container with an opening function of the present invention as described above, a finger is formed by tilting a pushing operation plate extending upward with a finger sideways with an opening member attached in an overcap shape to a container sealed with a lid. Since the pushing portion can be pushed into the container and the lid material can be broken open by the blade portion without protruding into the container, there is no sanitary problem that the contents touch the finger. Further, in a state where the container is opened, the push-in portion is pushed into the container, and the push-in operation plate is tilted sideways, and the contents between the push-in operation plate and the opening end of the container main body are the contents. When the contents are taken out using this outlet as a drinking mouth (the mouth is attached to the container and the contents are drunk), the pushing portion and the pushing operation plate do not get in the way, Since there is no part which protrudes largely on the upper surface side of the opening member, the appearance of the container in the opened state is good.

  An overcap-shaped opening member mounted on a container sealed with a lid can be opened without piercing a finger into the container or causing liquid splash, and is disturbed by the opening member. The purpose of making it possible to take out the contents without any problems and having no problem with the appearance in the opened state, as specifically shown in the following examples as the best mode, A pushing operation plate extending upward in a direction substantially orthogonal to the upper surface of the pushing portion is integrally formed in the vicinity of the hinge connecting portion at the pushing portion of the opening member, and the hinge connecting portion is moved down by pushing the pushing operation plate sideways. With the configuration in which the outlet of the contents is formed between the pushing operation plate and the opening end of the container body in a state where the pushing portion is pivoted downward to the fulcrum and the lid is broken and opened by the blade portion. It was realized in Ukoto.

  A pushing portion 16 formed so as to be rotatable with respect to the top plate portion 13 using the hinge connecting portion 15 as a turning shaft protrudes downward from an outer edge of a substantially semicircular arc-shaped end portion of the pushing portion 16. As described above, the blade portion 17 for breaking and opening the sheet-like lid member 3 is integrally formed, and in the vicinity of the hinge connecting portion 15, a substantially semi-disc-shaped linear end portion of the pushing portion 16 is formed. The push-in operation plate 18 is formed integrally with the upper surface of the push-in portion 16 and extends upward in a direction substantially orthogonal to the upper surface.

  In this embodiment, the depression 16a is formed on the upper surface side of the pushing portion 16 so as to be recessed downward from the upper surface, and the pushing operation plate 18 is formed across the upper surface of the pushing portion 16 and the depression 16a. Yes. Further, both side portions of the pushing operation plate 18 and the outer peripheral wall 11 of the opening member 4 are connected by a weakening portion 19 that can be easily broken, and when the pushing operation plate 18 is pushed down during the opening operation, the weakening portion 19 is connected. Is to be broken.

  Further, in this embodiment, a plurality (in the embodiment, in order to connect the upper surface of the pushing portion 16 (the portion other than the concave portion 16a) and the pushing operation plate 18 on the upper surface side of the pushing portion 16 as shown in FIG. Four support walls 20 are formed. On the other hand, as shown in FIG. 4, a plurality of (5 in the embodiment) reinforcing ribs 21 are formed on the lower surface side of the pushing portion 16 so as to connect the lower surface of the pushing portion 16 and the blade portion 17. .

  In this embodiment, the blade portion 17 projecting downward from the arcuate outer edge of the push-in portion 16 has a flange of the container body 2 when the push-in portion 16 is pivoted downward using the hinge connecting portion 15 as a pivot shaft. The blade portion 17 extending in an arc shape passes slightly inside the inner peripheral end of the portion 2a, and is formed in a sheet-like shape at a position close to the inner peripheral end of the flange portion 2a of the container body 2. The lid member 3 is broken in an arc shape. The arcuately extending blade portion 17 is formed so that the central portion in the circumferential direction protrudes most downward, and the distal end (lower end) of the central portion in the circumferential direction of the blade portion 17 when the pushing portion 16 rotates. First comes into contact with the lid 3. The central reinforcing rib among the plurality of reinforcing ribs 21 is connected to the central portion in the circumferential direction of the blade portion 17.

  Further, in the present embodiment, the pushing operation plate 18 has an outer periphery in the vicinity of both sides thereof as shown in FIG. 5 in a state where the pushing portion 16 is rotated downward and the lid member 3 is broken and opened by the blade portion 17. The end 18b is positioned outside the inner peripheral end of the flange portion 2a of the container main body 2, and the outer peripheral end 18a near the center is positioned inside the inner peripheral end of the flange portion 2a of the container main body 2. A content outlet (drinking mouth) A is formed between the outer peripheral end 18a near the center of the push-in operation plate 18 and the inner peripheral end of the flange portion 2a of the container body 2. It is like that.

  Further, in the present embodiment, a position at a predetermined interval between the upper surface of the lid member 3 and a lower portion on the inner surface side of the outer peripheral wall 11 on the pushing portion 16 side of the outer peripheral wall 11 of the opening member 4. Further, a locking projection 22 having an inner diameter smaller than the outer diameter in the vicinity of both side portions of the pushing operation plate 18 is formed, thereby rotating the pushing portion 16 downward as shown in FIGS. In the state where the lid member 3 is broken and opened, the push-in operation plate 18 is in the vicinity of both sides thereof, and the locking projection 22 of the opening member 4 and the lid member 3 (the flange portion 2a of the container body 2 below it). And is locked by the locking projection 22 so as not to rotate upward.

According to the container 1-out with opening feature of the present embodiment as described above, upon opening the container by opening member 4, it can also be pushed down directly put a finger into the recess 16a of the insert member 16, so Without pushing the pushing operation plate 18 extending upward from the pushing portion 16 sideways with a finger, the pushing portion 16 is rotated downward with the hinge connecting portion 15 as a fulcrum, and therefore, from the outer edge of the pushing portion 16. By the blade portion 17 projecting downward, the portion of the lid member 3 located below can be broken open.

  In this way, by pushing the pushing operation plate 18 sideways, the container can be opened without piercing the finger into the container, and the container is filled with the contents just below the lid 3. , There is no hygiene problem with touching the contents. Further, the push-in operation plate 18 extending upward is in a state of falling sideways when the container is opened, and the drinking mouth A is interposed between the push-in operation plate 18 and the flange portion 2a of the container body 2. Therefore, when the contents are drunk from the drinking mouth A, the push operation plate 18 does not get in the way, and there is no part that protrudes greatly on the upper surface side of the opening member 4, The appearance of the container in the opened state is good.

  Furthermore, in this embodiment, when the outer peripheral wall 11 of the opening member 4 and both sides of the push-in operation plate 18 are connected by the weakening portions 19 that are easily broken, when the push-in operation plate 18 is pushed down during the opening operation, Although the weakened portion 19 is broken, the pushing portion 16 of the unsealing member 4 is inadvertently rotated and the lid member 3 is unintentionally rotated unless a force sufficient to break the weakened portion 19 is applied. There is no such thing as breaking open.

  In this embodiment, an appropriate number of support walls 20 are formed so as to connect the upper surface of the push-in portion 16 and the push-in operation plate 18, so that when the push-in operation plate 18 is pushed down with a finger, It is possible to prevent only the push operation plate 18 from being curved and the push portion 16 from rotating, and the blade portion 17 can be broken and opened by the blade portion 17 by reliably turning the push portion 16.

  In the present embodiment, the locking projection 22 is formed on the lower portion of the inner surface of the outer peripheral wall 11 of the opening member 4 so that the pushing portion 16 is rotated downward and the lid 3 is broken and opened. Then, the push-in operation plate 18 is clamped between the engaging projection 22 of the opening member 4 and the sheet-like lid member 3 (the flange portion 2a of the container body 2 below it) in the vicinity of both sides thereof. Thus, when the contents are taken from the opened drinking mouth A, the pushing portion 16 of the opening member 4 pushed into the container is locked. There is no possibility that it will get in the way by reverse rotation and return.

  Further, in this embodiment, the outer peripheral end 18b near the both side portions of the push-in operation plate 18 is formed on the flange portion 2a of the container body 2 in a state where the push-in portion 16 is rotated downward and the lid member 3 is broken and opened. Since the push-in operation plate 18 is positioned outside the inner peripheral end, the push-in operation plate 18 abuts on the flange portion 2a of the container body 2 in the vicinity of both sides thereof, and the push-in operation plate 18 enters the container beyond that. There is no.

  On the other hand, the outer peripheral end 18a in the vicinity of the center portion of the push-in operation plate 18 is set to be located inside the inner peripheral end of the flange portion 2a of the container body 2, and this portion 18a and the flange portion of the container body 2 are set. The outlet of the contents is formed between the outer peripheral edge 18a and the outer peripheral edge 18a in the vicinity of the center of the push-in operation plate 18 by appropriately changing the degree of the shape. The shape of the opening (drinking mouth A) of the container can be freely changed according to the contents.

  Further, in the present embodiment, when the pushing portion 16 is rotated downward, the blade portion 17 extending in an arc shape passes slightly inside the inner peripheral end of the flange portion 2a of the container body 2. The sheet-like lid member 3 is broken (sheared) into a circular arc shape at a position close to the inner peripheral end of the flange portion 2a of the container body 2, and the lid by the blade portion 17 thereby. The material 3 can be ruptured cleanly along the inner peripheral edge of the flange portion 2a, and the subsequent discharge of the contents can be made smooth.

  In addition, the blade portion 17 extending in an arc shape is formed so that the central portion in the circumferential direction protrudes most downward, and the tip (lower end) of the central portion in the circumferential direction of the blade portion 17 is rotated when the pushing portion 16 is rotated. At first, the lid member 3 is brought into contact with the cover member 3, but the force for pushing down the push-in operation plate 18 is concentrated at one point at the tip of the central portion in the circumferential direction of the blade portion 17, and the lid member 3 is easily broken. After that, by further rotating the push-in portion 16, the lid member 3 can be easily broken into an arc shape along the shape of the blade portion 17 extending in an arc shape.

  In the present embodiment, the plurality of reinforcing ribs 21 are formed so as to connect the lower surface of the push-in portion 16 and the blade portion 17, whereby the blade portion 17 comes into contact with the sheet-like lid member 3. At this time, the blade portion 17 can be prevented from being deformed, and the lid member 3 can be reliably broken by the blade portion 17. In particular, when the blade portion 17 is set to pass slightly inside the inner peripheral end of the flange portion 2a of the container body 2 as in the present embodiment, the lid member 3 is provided in the vicinity of the flange portion 2a. Therefore, the blade portion 17 is easily deformed by losing the rigidity of the lid member 3. However, by providing the reinforcing rib 21, the blade portion 17 can be deformed even when the lid member 3 has high rigidity. It can be effectively prevented.

  In addition, about the reinforcement rib 21 formed in the lower surface of the pushing part 16, in a present Example, the center reinforcement rib of the center of the five reinforcement ribs is the circumferential direction center part of the blade part 17 which contacts the cover material 3 initially. By doing so, the deformation of the blade portion 17 can be particularly effectively prevented, and the outer reinforcing rib of the five reinforcing ribs can be connected to the upper surface of the pushing portion 16. It is arranged in the vicinity of the position corresponding to the formed support wall 20 (specifically, the position corresponding to the position between the two support walls 20). By doing so, the pushing portion 16 is made rigid. Thus, the pressing force applied to the pressing operation plate 18 can be efficiently applied to the blade portion 17 via the support wall 20.

Having described an embodiment of a container-out opening with features of the present invention, the present invention is not limited to the specific structure of the embodiment as described above, for example, specifically the opening member The number and position of the supporting walls and reinforcing ribs formed on the push-in part can be changed as appropriate, and in some cases, they can be omitted, and the outer peripheral wall and the push-in operation plate Needless to say, the weakened portion for connecting to the inner surface and the locking projection provided on the inner surface side of the outer peripheral wall can be omitted as appropriate.
