Description

Container with unsealing means {Container with unsealing means}

The present invention relates to a container with an opening means. More specifically, the present invention relates to a container with an opening / outlet member which opens a sealing film of the container body filled with the contents and constitutes an outlet of the contents.

Conventionally, many containers have been proposed to keep the spout in a sealed state in an unused state, and to open and use a sealing film provided at the spout at the start of use. Moreover, the cap structure provided with the tamper-proof prevention mechanism (opening prevention member) is also known so that it may not be inadvertently opened in an unused state.

In Patent Document 1 (Japanese Patent No. 3024089) proposed by the applicant first, a container in which an opening preventing member (ring-shaped band portion) is provided at the lower end of the outer circumferential wall, and the contents of which is filled with an intermediate plug having a sealing film (thread) are formed. In the bottle container which sealed and fixed to the head part of a main body, and the outer cap in which the guide cylinder for opening a sealing film was formed on it was cut out, after cutting an opening prevention member from the lower end of an intermediate stopper outer peripheral part, A description is given of pressing the outer cap from above to lower the outer cap, opening the sealing film with a guide tube formed in the outer cap, and fixing the outer cap to the container head. In this prior art, there is no need to remove the outer cap at the time of opening work, there is no risk of mixing of germs or dirty fingers, and there are many advantages such that the container can be kept sealed even after the start of use. However, there is a problem that the trace after cutting the unsealing member remains, which is not aesthetically desirable, and a relatively large force is required for pressing the outer cap at the time of opening.

Similarly, in Patent Literature 2 (Japanese Patent No. 4045277) proposed by the applicant first, the unsealing member is provided in a separate body from the cap, and the unsealing member is opened and opened in a bottle container of a type that starts use. After the contents are filled from the head of the container main body, the cap is attached to the head of the container main body in a sealed state, and the cap is again screwed onto the shoulder part having the spout which is sealed at the tip end. The contents of the conical projections attached to the cap are press-fitted to the spout and then opened. In this prior art, since the rotation of the cap at the time of screwing is used for opening, it has various advantages, such as being easy to open with a relatively small force, but the opening hole formed is limited to a very small one, There also exists a problem that it is difficult to apply to the container which needs to enlarge a hole relatively.

Similarly, in Patent Document 3 (Japanese Patent No. 378224) proposed by the present applicant, the neck of the container body in which the inner cap provided with the sealing film is filled with the inner cap having a sealing film interposed between the inner cap and the cap body ( In the bottle container of the type which attaches in a sealed state, removes an opening prevention member, and opens it, and starts using, WHEREIN: When cutting a cap main body again into an inner cap, the cutting blade attached to a cap main body rotates a specific angle. The contents which open | release the said sealing film by leaving a cutting | disconnection remainder by this are described. In this prior art, since a small diameter cutting blade is rotated and opened by screwing rotation of a large diameter cap, even if the large diameter cap is rotated with a relatively small force, a large rotational force and a pressing force are applied to the small diameter cutting blade. Since this is added, there are various advantages, such as being able to form a opening hole which is relatively large and has little burr formation at the edge of the opening hole other than the cutting remainder. However, if it is intended to be applied to a container body of a relatively flexible and flexible material such as a tube container of the form of this technique, or a container body forming a relatively small opening hole in which the rotational force of a large diameter cap is greatly amplified, Since a relatively large pressing force as well as a large rotational force act on the periphery of the encapsulation film, it has been recognized that the periphery of the encapsulation film is abnormally deformed or broken.

Japanese Patent No. 3024089 Japanese Patent No. 4045277 Japanese Patent No. 3978224

This invention exhibits the remarkable effect as described in following (a)-(h) by providing the above characteristics.

(A) Since the rotation of the cap at the time of screwing is used to open the openable part to form the opening hole, it is possible to apply a relatively large pressing pressure to the opening means such as the cutting blade with a relatively small cap rotational force. .

(B) Rotation of the cap at the time of screwing is used to form the opening hole, but since the opening / outlet member provided with the opening means is freely held and held in the cap, even if the cap is screwed and rotated, Forced rotational force is not applied to unopened ejection member. And since the rotation is prevented with respect to the container main body head part in which the openable part was formed, or at least it does not rotate actively, although the comparatively large pressing force acts from the opening means, such as a cutting blade, at the periphery of the openable part, Large torque does not work. Therefore, even in a container made of a material having a relatively high flexibility and flexibility or a material having a relatively low strength, such as a container of a squeezing type, or even a container having a relatively small opening, the peripheral portion of the openable part is abnormally deformed, Without breaking, it is possible to form easily and a good opening hole easily.

(C) If the opening / outlet member including opening means such as a cutting blade is prevented from rotating with respect to the container body head, the periphery of the openable portion does not have any rotational force, so It is possible to better prevent abnormal deformation and destruction of the periphery. In addition, the opening means including the cutting blade, it is possible to form the engaging portion that is left without being cut with the cut line in the exact angle range.

(D) Since the pressing rib formed on the inner surface of the cutting blade under the cylindrical member presses down the sealing film inside the cutline, the pressing rib assists the downward movement from the cut-off left portion of the sealing film. In addition, the pressing rib enters between the cutting blade and the sealing film inside the cutline, widens the clearance of the cutting line, and reduces the contact resistance of the cutting blade, thereby further reducing the cap rotation force required for pressing cutting.

(E) When the cutting blade is composed of a plurality of continuous cutting edge portions, the pressing pressure is dispersed, and it is possible to better prevent deformation of the encapsulation film peripheral portion due to the pressing pressure of the cutting edge.

(F) The press-cut sealing film is pressed down by a flat portion where the cutting edge of the lower portion of the cylindrical member is not formed, and the portions other than the connecting portion left without being cut down are hung down from the connecting portion by the outer peripheral surface of the flat portion. Since it is held and held in a state of being pressed down on the inner circumferential surface of the head of the container body, there is almost no problem in dispensing the contents, and there is no case of mixing or floating in the contents to impart a foreign object feeling.

(G) At the time of non-use, the cap, the opening-outlet member and the opening prevention member can be attached to the head of the container body after the contents filling in an integrated state, so that the assembly of the container can be easily performed in one step. Do.

(H) It is possible to clearly identify whether or not an unused state is determined by the presence or absence of an opening preventing member, the presence or absence of the opening of the opening / outlet member to the container body head, the presence or absence of the opening hole at the head end, and the like.

The present invention relates to a container with an unsealing-outlet member which opens an openable part of the container body filled with the contents and constitutes an outlet of the contents.

The container of the present invention includes at least the following (a) container body, (b) cap, and (c) opening and dispensing member.

(a) The container main body includes an openable part at an upper end, a locking part capable of stopping the opening / outlet member from being pulled out, a cylindrical head having a male thread on its outer peripheral surface, and a body part. will be.

(b) The cap is provided with a holding and holding portion capable of holding and holding an opening, an outlet member, and a female thread that can be screwed into the male thread, and detachable from the head of the container body by the screwing. It can be attached freely.

(c) The opening / outlet member is provided with opening means for opening the openable portion to form an opening hole, and engaging the opening portion with the stopper portion to prevent the opening / outlet member from falling into the head of the container body. And a spout for dispensing the contents of the container body when the opening portion and the opening / outlet member are stopped in a state where the head of the container body is prevented from falling out, and the cap and the holding part are held and held. In the state, when the screw is engaged with the rotation of the cap to move to the body side with the cap, by the opening means to open the openable portion of the upper end of the head to form the opening hole, the engaging portion is hooked It engages with a stop and becomes a fall prevention state in the head part of a container main body. The movement to the trunk portion side is parallel movement in the axial direction without accompanying forcible rotation.

The container of the present invention can further ensure the unused state of the container reliably by further providing an opening preventing member which prevents the opening means from contacting the openable part in an unused state. . The unsealing member is provided in a container in an unused state, restricts the axial movement of the cap toward the container body body side with the rotation of the cap at the time of screwing, and is held and held in the cap holding and holding portion. A member for preventing the opening means formed on the opening / outlet member axially moving together from contacting with the opening possible portion, for example, an opening through which the cylindrical head portion can penetrate, and the opening means opening the opening means. It is possible to provide a cylindrical portion having an axial length as a spacer that prevents contact with the possible portion.

If the container is not provided with an opening preventing member, the opening / outlet member is separated from the container body or the cap, or the opening / outlet member is held and held so that the opening-capable part is inadvertently opened. Although it is necessary to distribute and display separately from it, when it is provided with an anti-opening member, even if it distributes and displays in the state which assembled all of them, it is possible to prevent inadvertent opening.

At the start of use, the opening preventing member is detached, and the cap in which the opening / outlet member is held and held therein is screwed and attached to the head of the container body. In accordance with the rotation of the cap in the screwing direction, the unsealed opening / outlet member held in the cap is axially moved toward the body with the cap, and the opening means opens and opens the openable portion of the head end. Form a hole. At this time, the opening-outlet member is hooked to the head of the container body, and thereafter, functions as an outlet member integral with the head of the container body.

Although the material of a container main body, a cap, an opening-outlet member, and an opening prevention member is not specifically limited, Generally, synthetic resin, a metal, glass, these composite materials, a composite, etc. can be used. Moreover, it is possible to employ | adopt various physical properties according to a content, a use, a component, etc., such as transparency, opacity, partial transparency, heat resistance, and gas impermeability. Generally, synthetic resins are preferred from the viewpoints of light weight due to low specific gravity, ease of forming various aesthetic design containers and functional containers. Although the synthetic resin to be used is not limited, For example, olefin resins, such as polypropylene and polyethylene, polyester resins, such as PET, ABS resin, etc. can be used according to content, a use, a component, etc. .

Although the content filled in a container main body is not limited, Generally, it is a liquid, solid, powder, solid-liquid mixture, paste, frozen substance, etc., and cosmetics, a detergent, various chemical | medical agents, drinks, foodstuff, etc. can be illustrated.

Below, each component is further demonstrated.

[Container body]

The container main body in this invention is equipped with the cylindrical head part and the trunk part which is a main accommodating part of a content at least. It is also possible to provide a shoulder portion inclined horizontally to downward between the body portion just under the head.

The cylindrical head has a male thread such as an openable part, a locking part capable of locking the opening / outlet member in a locked state, and a male thread that can be screwed into female threads such as a female screw formed on the cap. Have at least.

A sealable part can be made into the sealing film which closed the said head part upper end. It is preferable for the sealing film to make the contact part of the cutting blade which comprises an opening means into the notch part which is thinner than another part, and to make continuous press cutting of the contact part of a cutting blade easy.

The locking portion which can open and close the ejection-outlet member in the preventive state from being pulled out is an annular protrusion that protrudes radially outward from the entire circumference of the upper end of the upper portion of the small cylindrical portion constituting the cylindrical head. desirable.

Male threads, such as male threads, can be formed in the outer peripheral surface of the large cylindrical part of the lower part which comprises a cylindrical head part. Although it is preferable that the male spiral is continuous, it can also be provided intermittently, and it can also be made into any of forging and many.

When the opening means opens the openable part, or after the opening / outlet member is stopped in a state of preventing the cylindrical head from falling out, the opening / outlet member including the opening means does not rotate with respect to the head. It is possible to form the anti-rotation part in the head. As a rotation prevention part formed in a head part, it is possible to set it as the longitudinal rib which sliding-contacts the axial protrusion of the outer cylinder inner surface of an opening-outlet member. It is preferable to provide a plurality of longitudinal ribs at equal intervals on the outer periphery of the small cylindrical part of the upper part which comprises a cylindrical head part.

It is preferable that a container main body is equipped with the rotation limit control part which restrict | limits the rotation limit to the direction which is screwed and attached with respect to a cap or a tear prevention member. Such a rotation limit regulating portion can be formed as a rotation limit regulating protrusion which is formed at the proximal end of the head and has a restricting surface substantially perpendicular to the tangent of the proximal end of the proximal end. The restricting surface is most preferably perpendicular to the tangent of the proximal end of the proximal end, but may be allowed if it is within the range of ± 40 degrees (preferably ± 20 degrees) with respect to the vertical surface. The proximal end face is opposite to the facing portion of the positioning protrusion in order to hold and hold the cap or the tear preventing member at the position when the positioning protrusion formed on the cap or the tear preventing member faces the regulating surface. It is desirable to have a portion to engage with. As such a part to engage, it is possible to set it as the climbing protrusion which the positioning protrusion can climb by the elastic deformation.

The body portion of the container may adopt various shapes and structures such as rotational symmetry, rotational asymmetry, circular cross section, elliptical cross section, polygonal cross section, etc. It may be preferable to set it as.

The container body can not only manufacture the whole body by a single process by injection molding, etc., but also retain and hold the upper end of the flexible tubular tube constituting the body part in the mold cavity, and inject the synthetic resin into the mold cavity to form the head part. And it is also possible to manufacture by inject-molding a shoulder part and integrating the synthetic resin of a shoulder part with the upper end of a tube. In the case of the container main body which opened the lower end of a container, the backflow prevention member which prevents the backflow of the ejected content into the container main body may be inserted and fixed from the lower end opening into a head part. Then, after the contents are filled from the lower end opening, the lower end of the body portion may be sealed by appropriate sealing means such as ultrasonic welding, hot plate heating sealing, or the like. Furthermore, after filling the contents from the neck end opening connected to the body part, the inner cap having an openable part, a stop part, a male thread, and a backflow preventing member, if necessary, is sealed and fixed to the neck to form a head. It is also possible to make the main body. Resin parts, such as a cylindrical tube of a trunk part, can also be made into the multilayered structure containing various resin layers, such as a gas barrier layer and an contact bonding layer. In the case of a bottle container, it is also possible to make at least a sealable part the material which can be opened, such as resin, and to make glass and a metal other than that.

[cap]

The cap is provided with a female thread such as a female thread that can be screwed into a male thread of the outer circumferential surface of the head of the container body head and a holding and holding part capable of holding and holding an opening, an outlet member, and the container body by the screwing. It is comprised so that the said head part may be detachably attached to a said head part without the opening prevention member or the opening prevention member.

Such a cap has a ceiling wall, an outer cylinder hanging down from the outer periphery of the ceiling wall, an inner cylinder coinciding with the outer cylinder, and an inner cylinder hanging down from the lower surface of the ceiling wall. It is possible to have a holding | maintenance holding part which engages with an opening-opening | outlet member.

The holding and holding part is loosely held and held so that the opening and dispensing member including the opening means does not fall out from the cap, and the head part of the container body along with the cap is rotated along with the cap at the time of screwing. It is possible to make it move to the inside, and it is possible to set it as the annular projection of the inner cylinder inner peripheral surface loosely fitting to the annular recess of the opening-outlet member outer peripheral surface. The opening / outlet member loosely held or held in the inner cylinder of the cap can be held and held without being pressed against a packing fixed to the inner wall of the cap by adhesion or the like, thus shrinking the packing in an unused state. It is possible to maintain the elasticity without causing it. When opening the container and starting to use, the opening / outlet member is locked to the container body head, and when the cap is locked, the upper surface of the ceiling wall of the opening / outlet member is the ceiling surface or cloth of the inner tube of the cap. It is possible to abut the packing fixed to the scene. Even after the opening / outlet member is stopped in a state where the container body head is prevented from falling out, the retaining-holding portion and the annular recess may contact each other, but their dimensions include the attachment of the cap to the container body head, It is configured in advance so that it does not interfere with removal.

When the cap is rotated and attached to the container body head in the screwing direction, the rotation limit regulating portion formed in the container body head is formed so that the cap does not rotate beyond the rotation limit and is held and held at the rotation limit position. And a positioning protrusion that engages with the positioning recess between the and the ascending protrusions.

It is possible to use a packing fixed by adhesion or the like on the inner surface of the ceiling wall of the cap as a member capable of closing the ejection opening of the opening and the ejection opening member which is locked in a state where the container body is prevented from falling out. It is also possible to use a stopper formed on the lid of the hinge cap. In the case of using a stopper formed on the lid of the hinge cap, an opening is formed in the ceiling wall, and the outlet port exposed from the opening can be closed by a stopper on the inner surface of the lid supported by the hinge. .

As a material of a cap, synthetic resins, such as polypropylene, glass, a metal, etc. are mentioned.

[Unopening or outlet]

The opening / outlet member engages with the opening means for opening the openable part to form the opening hole, and the stopper portion of the head of the container body when forming the opening hole, thereby opening and opening the outlet member to the head of the container body. And a spout for dispensing the contents of the container body when the opening portion and the opening / outlet member are prevented from falling out of the head of the container body. In the state of holding and retaining in the state of the screw, when the screw is engaged, the cap moves together with the cap to the body part of the container body, and the opening means opens the opening of the upper end of the head to form an opening hole. The engaging portion is configured to engage with the stopping portion so as to be prevented from falling out of the head of the container body.

After removal of the unsealing member, the cap is placed on the head, and when the cap is rotated in the screwing direction, the opening / outlet member held and held in the cap is axially moved to the body side with the cap, and the opening means The openable part of the upper end is opened to form an opening hole, and the opening / outlet member is opened with respect to the head of the container body in a state where the annular sealing part of the opening / outlet member is in contact with the annular sealing surface around the opening hole. It hangs in a fall prevention state, and the opening-out spout member will function as a spout outlet member integral with a container main body after that.

Since the rotation of the cap at the time of screwing is used for opening the openable part to form the opening hole, it is possible to apply a relatively large pressing pressure to the opening means including the cutting blade with a relatively small cap rotational force. Since the opening / outlet member is only held loosely in the cap when the opening means is opened, the periphery of the openable portion does not rotate integrally with the cap. This works, but at least large torque does not work. For this reason, even in a container made of a material having a relatively high flexibility and flexibility or a material having a relatively low strength, such as a container of a squeezing type, or even a container having a relatively small opening, the peripheral portion of the openable part is abnormally deformed, Without breaking, it is possible to form easily and a good opening hole easily. When the opening / outlet member is configured to prevent rotation of the container body head, the rotational force of the cutting blade does not act at all on the periphery of the openable part, so it is better to prevent abnormal deformation and breakage of the periphery of the openable part. It is possible.

Such an opening / outlet member is a ring-shaped ceiling wall in which a spout is formed in the center, a tubular portion extending downward from the ceiling wall, and has an outer cylinder having a horizontally long rectangular cross-sectional through hole, and the outer cylinder. It is possible to comprise a tubular portion having a ring-shaped gap between the inner cylinder having the opening means formed at the lower portion and the inner and outer cylinders concentrically and the annular ceiling surface being the annular sealing portion.

It is preferable that the unsealing means which opens a tearable part and forms a tear hole includes the cutting blade formed in the lower part of the inner cylinder which comprises a tear opening / outlet member. The cutting edge is pressed to form a cut line by cutting, preferably around 240 to 340 degrees, more preferably 260 to 320 degrees around the openable part such as a sealing film. When the cutting blade which presses and cuts such a range is comprised by the continuous plurality (preferably 2-5 pieces) of cutting-type cutting blade parts, press cutting pressure is disperse | distributed and the edge part of the sealing film by the pressing cutting pressure of a cutting blade It is possible to better prevent deformation. It is possible to form one or two or more axially extending pressing ribs on the inner circumferential surface of the cutting blade formed at the bottom of the inner cylinder. The pressing rib is preferably configured to extend axially rearward from a position slightly behind the distal end of the mountain cutting blade portions of the plurality of mountain cutting blade portions. The pressing rib pushes down the encapsulation film inside the cutline formed by the cutting blade, and enters in the cutline to form a clearance so as to prevent contact between the inner peripheral surface of the cutting blade and the encapsulation film inside the cutline, thereby reducing contact resistance and cutting It is possible to reduce the force required for pressing and cutting the sealing film by the blade.

The portion in the range of 20 to 120 degrees (preferably 40 to 100 degrees) that is not cut by the cutting blade functions as a joining portion that does not mix the encapsulated sealing film with the contents in the container. In order to form such a coupling part, it is preferable to form a flat part in the lower part in which the cutting blade of the said cylindrical member is not formed. The cylindrical member including the flat portion at the bottom thereof is pressed and cut, so that the sealing film pressed down by the pressing ribs hangs down from the engaging portion, and is deformed so as to be pressed down on the inner circumferential surface of the container body head, thereby maintaining the state. Since it is possible to do this, the sealing film pressed down does not prevent the smooth ejection of the content.

When the opening means opens the openable part or after the opening / outlet member is stopped in a state of preventing the cylindrical head from falling out, the opening / outlet member provided with the opening means does not rotate with respect to the head. It is preferable to form the anti-rotation part. As the anti-rotation part formed in the opening-outlet member, it can be set as the axial protrusion which extends in the axial direction to the inner peripheral surface of the outer cylinder which comprises a cylindrical part, and makes sliding contact with the longitudinal rib of the head outer peripheral surface. It is preferable that the tip of the axial protrusion is provided in a tapered shape at a predetermined position so as to be in sliding contact with the longitudinal rib at any position at equal intervals in the circumferential direction. By forming such an anti-rotation part, it is possible to better prevent abnormal deformation and breakage of the periphery of the openable part, and it is possible to form the joining part left without being cut and cut in the correct angle range, and also the container It is possible to prevent unnecessary rattling of the unsealed opening / outlet member after the body head is stopped.

One or more hooks formed by engaging the opening-outlet member with the container body head in the preventive state may be of any structure, but protrude from the outer circumferential inner circumferential surface of the lower portion of the transverse through-hole having a horizontally rectangular section. It is possible to make a custom projection.

The material of an unsealing-outlet member is harder than an openable part, and, in the case of synthetic resin, polyester resins, such as PET, are mentioned, for example.

[Opening prevention member]

The opening preventing member is provided in the container in an unused state, restricts the axial movement of the cap toward the container body body side by the rotation of the cap at the time of screwing, and opens the holding and holding opening / outlet member held in the cap. The means is prevented from contacting the openable part.

As an opening prevention member which exhibits such a function, it is possible to set it as the member which can be interposed between the screwed cap and the container main body body part or the shoulder part. Although the shape and structure are not limited, it is preferable to have an opening through which a cylindrical head can pass through an aesthetic appearance, and a tubular portion having an axial length as a spacer with the cap or the container body body portion and the outline contour being substantially the same. Do.

The anti-opening member can be configured to be coupled to the lower part of the cap (for example, the outer cylinder bottom surface) or the container body (for example, the shoulder upper surface) via the easy-to-cut coupling portion, to further ensure the unused state. However, when it is separated from a cap and a container main body, since the cutting trace of the easy coupling | bonding part does not remain | survive and freedom in design design of an unused container also increases, it is preferable. In addition, it is preferable to make an opening prevention member into the external appearance (for example, a different color body) which a cap and a container main body can distinguish clearly so that the unused state and use state of a container main body can be seen at a glance.

The anti-opening member in the case of being separated from the cap and the container main body is preferable because it can be easily attached and detached to the head of the container main body as long as it can be handled integrally with the cap. In order to be able to handle integrally with a cap, the unsealing member can be provided with the fitting piece which the outer peripheral surface elastically press-contacts the inner peripheral surface of a cap outer cylinder. Although the fitting piece can be formed continuously in the whole circumference, from a viewpoint of material saving, it is preferable to install a plurality of pieces (for example, 2-6 pieces) intermittently at predetermined intervals in the circumferential direction. .

When the cap, which is unintentionally held and held by the unsealing member, is attached to the head of the container body by rotating in the screwing direction, the unsealing member is formed on the proximal end of the head of the container body to regulate the rotational limit thereof. It is preferable to provide a positioning protrusion which can be engaged with the positioning recess.

As a material of an anti-opening member, comparatively hard synthetic resins, such as ABS, glass, a metal, etc. are mentioned.

<Cap (4)>

FIG. 3 (a) shows a longitudinal cross-sectional view (an elliptical long axis side longitudinal cross section and an elliptic short axis side longitudinal cross-sectional view on the left side from the center line) of the cap 4 above the container 1 in an unused state, and FIG. 7 (a ) Shows a longitudinal cross-sectional view of the cap 4 on the upper part of the container 1 after the start of use (an elliptical long axis side longitudinal cross-sectional view and an elliptic short axis side longitudinal cross-sectional view on the right side from the center line).

The cap 4 is in an elliptical ceiling wall 41, a transverse elliptical outer cylinder 42 extending downward from the outer circumferential portion of the ceiling wall 41, and an outer cylinder 42 of the elliptical ceiling wall 41, and is lowered from the ceiling wall 41. A cylindrical inner cylinder 43 hanging down by the inner cylinder 43 and a disk-shaped packing 44 fixed to the inner surface of the ceiling wall 41 in the inner cylinder 43 by bonding or the like are provided.

The inner surface upper portion of the inner cylinder 43 is loosely fitted into the annular recess 54a of the outer peripheral surface of the opening / outlet member 5 so that the opening / outlet member 5 does not fall from the inside of the inner cylinder 43. The female thread which the holding-and-holding ring-shaped protrusion 43b is screwed with the male screw 27 provided in the lower part of the inner surface of the inner cylinder 43 in the outer peripheral surface of the head part 21 of the container main body 2, the large cylindrical part 21b ( 43a) can be engaged with the positioning recessed part 28c formed in the head part 21 base end part 21c of the container main body 2 at the lower ends of the two elliptical long axis side of the inner cylinder 43. As shown in FIG. Positioning protrusions 45 (see Fig. 7 (b)) are formed, respectively.

A fitting piece 32 formed on the upper surface of the unsealing member 3 is fitted to the lower inner surface of the outer cylinder 42 of the cap 4 in an unused state so that the cap 4 and the unsealing member 3 are integrally formed. Since it can be handled with, it is possible to perform their attachment and removal to the head of the container body 2 in one step.

At the start of use, after removing the opening prevention member 3 from the lower portion of the outer cylinder 42 of the cap 4, the cap 4 in which the opening / outlet member 5 is held and held in the inner cylinder 43 is It is attached to the head 21 of the container main body 2.

<Opening, outlet member (5)>

4 and 5 show the opening / outlet member 5. Fig. 4 (a) is a plan view, Fig. 4 (b) is a front view, Fig. 4 (c) is a side view, Fig. 5 (a) is a longitudinal sectional view, and Fig. 5 (b) is a partial bottom view.

The opening-out spout member 5 is comprised from the ring-shaped ceiling wall 51 in which the spout 52 was formed in the center, and the cylindrical part 53 which hangs down from the ceiling wall 51. As shown in FIG. . The cylindrical portion 53 includes an outer cylinder 54, an inner cylinder 56 concentric with the outer cylinder 54, and a ring-shaped void 55 therebetween.

The upper outer peripheral surface of the outer cylinder 54 is formed with an annular recess 54a that is loosely fitted with the annular projection 43b of the inner peripheral surface of the inner cylinder 43 of the cap 4. In the annular recess 54a, an outer cylinder through-hole 54b (see Fig. 4 (c)) having a horizontally long rectangular cross section provided at two point symmetrical positions is formed. The lower surface part of the outer cylinder through-hole 54b of the horizontally long rectangular cross section protrudes more than the inner peripheral surface of the outer cylinder 54, and the ring-shaped protrusion 25 which protrudes outward from the upper end of the head part 21 of the container main body 2 is carried out. An engaging protrusion 54e having an engaging surface 54f that can engage the lower surface is formed (see Fig. 5 (a)).

In the lower part of the inner circumferential surface of the outer cylinder 54, 12 axial protrusions 54c extending in the axial direction at equal intervals are formed, and between the adjacent axial protrusions 54c, the container body 2 head portion ( 21) 54 d of longitudinal grooves into which the longitudinal ribs 26 provided on the outer circumferential surface of the small cylindrical portion 21a can enter are formed. When the lower end of each axial protrusion 54c is in contact with the upper end of the longitudinal ribs 26, the opening / outlet member 5 is rotated by a predetermined angle so that the longitudinal ribs 26 are formed in the longitudinal grooves 54d. It is formed in taper shape (thin shape) so that it may enter. Therefore, even if the opening / outlet member 5 is in any rotational position with respect to the head part 21 of the container main body 2, the longitudinal rib 26 enters into the longitudinal groove 54d, and rotation is prevented.

The lower part of the inner cylinder 56 functions as an opening means, and the cutting blade 57 and the flat part 58 which can open the sealing film 24 of the head part 21 upper end of the container main body 2 are Formed. 6, the developed view of the lower part of the inner cylinder 56 containing the cutting blade 57 is shown. The cutting blade 57 is formed over the range of 280 degrees of the inner cylinder 56, and is comprised by the cutting blades 57a-57c which protrude in three shapes below. Although the center cutting blade part 57b is formed in the symmetrical mountain shape, the cutting blade parts 57a and 57c of both sides are formed in the shape of asymmetrical left-right asymmetrical which the front-end | tip was biased to the cutting blade part 57b side of the center. On the inner circumferential surfaces of the cutting blade portions 57a and 57c on both sides, there are formed pressing ribs 59 extending axially upward from positions slightly above the tip ends of the cutting blade portions 57a and 57c. As for the remaining 80 degree | times in which the cutting blade of the lower part of the inner cylinder 56 is not formed, the lower end is formed with the flat part 58. As shown in FIG. By such a cutting blade 57, the circumference | surroundings of the sealing film 24 are pressed slowly and cut | disconnected so that a cutline may be formed in the range of 280 degree | times, and a press rib will press down the sealing film 24 inside the cutline, Into the cut line, the encapsulation film 24 inside the cut line is deformed toward the center side, and a gap is formed between the inner peripheral surface of the cutting blade 57 and the encapsulation film 24 inside the cut line, thereby contacting the cutting blade 57. Reduce resistance. Since the opening-outlet member 5 including the inner cylinder 56 in which the cutting blade 57 was formed in the lower part is rotationally prevented with respect to the container main body 2 head 21 as mentioned above, since it is 280 degree | times In the sealing film 24 which the range was pressed correctly and cut | disconnected, the part corresponded to the remaining 80 degree range is exactly left as a connection part, and parts other than the connection part are further pushed down by the said flat part 58, The flat part The outer circumferential surface of (58) hangs down from the connecting portion thereof, and is held and held in a state of being pressed down by the inner circumferential surface of the head of the container body 2 (21) (see the sealing film 24 in Fig. 7 (a)). ]. Therefore, the sealing film 24 pressed down hardly interrupts the ejection of the content, and it does not mix or float in the content and gives a foreign object feeling. When the opening means including the cutting blade 57 opens the sealing film 24 to form the opening hole, the ring-shaped sealing surface around the opening hole at the tip of the container body 2 head 21 is opened? The engagement surface 54f of the upper surface of the engagement projection 54e on the inner surface of the outer cylinder 54 is brought into contact with the annular sealing portion of the ring-shaped cavity 55 of the spout member 5, and the head of the container body 2 head. It is engaged with the lower surface of the annular projection 25 at the tip of the part 21, and the opening / outlet member 5 is locked to the container main body 2 head 21 in the fall prevention state. Since the opening port-outlet member 5 communicates with the opening port 52 of the ceiling wall 51 via the opening hole and the inside of the inner cylinder 56, the head of the container main body 2 is thereafter. It functions as a spout member integral with 21.

When the opening / outlet member 5 is stopped in the preventive state from falling into the container body 2 head 21, the outer cylinder 54 cuts the main surface of the small cylinder portion 21a on the upper portion of the head 21. Covering, resulting in an outline contour substantially coincident with the large cylindrical portion 21b below the head 21.

<Opening prevention member 3>

Fig. 3 (a) is a longitudinal cross-sectional view of the unsealing prevention member 3 provided at the lower end of the cap 4 on the upper part of the container 1 in an unused state (left side of the ellipse long axis side, and right side of the ellipse short axis side longitudinal section from the center line). Is shown.

The opening prevention member 3 comprised separately from the container main body 2 or the cap 4 of this embodiment is a cylindrical part provided with the outer peripheral part of the elliptical cross section extended continuously from the lower end of the outer cylinder 42 of the cap 4. (31), fitting piece 32 having an outer circumferential surface fitted to the inner circumferential surface of the lower portion of the outer cap 42 of the cap 4, and an opening 33 through which the head 21 of the container body 2 can penetrate. And positioning projections 34 which can be engaged with the positioning recesses 28c formed in the base 21c of the head 21 of the container body 2 (Fig. 3 (b)). Reference].

The fitting pieces 32 are intermittently provided in the circumferential direction corresponding to four places of the elliptical long axis side both ends and the elliptic short axis side both ends, and their outer peripheral surfaces are elastically press-contacted to the inner peripheral surface of the cap 4 outer cylinder 42. Since it is fitted so as to fit, the opening prevention member 3 can be hold | maintained and hold | maintained so that it may not fall to the cap 4 lower part. Therefore, attachment and removal to the container main body 2 head part 21 can be performed in one process with the cap 4.

<Unopened container (1)>

1 and 3 show the container 1 in an unopened state. Fig. 1 (a) is a plan view, Fig. 1 (b) is a front view, Fig. 1 (c) is a side view, and Fig. 3 (a) is a partially enlarged longitudinal cross-sectional view (an ellipse long axis side longitudinal section from the center line, and an ellipse on the right side). (Short axis side longitudinal cross-sectional view) and FIG.3 (b) is a partial enlarged cross sectional view of the climb / rotation limit control part 28. As shown in FIG.

The container 1 in an unused state is provided with a container body 2, an opening preventing member 3, a cap 4, and an opening / outlet member 5 which is mounted in the cap 4 and is not visible from the outside. .

When the container body 2 is a tube container in which the upper end of the head 21 is sealed by the sealing film 24 and the lower end of the cylindrical tube is opened, the contents of the lower end of the body part are filled after the lower end of the body is filled. The contents are sealed, and the contents are held and held in a sealed state in the container main body 2 (in addition, FIG. 1 and FIG. 8 omit the illustration of the sealing state of the lower opening and the blocking part for convenience).

In the cap 4 before attaching to the container main body 2, the opening / outlet member 5 and the opening prevention member 3 are attached, and the cap 4 and the opening prevention member 3 are opened and opened. The outlet member 5 is comprised so that handling may be carried out integrally.

In order to mount the opening-outlet member 5 to the cap 4, the opening-outlet member 5 is inserted in the inner cylinder 43 of the cap 4, and the annular recess 54a of the outer peripheral surface thereof is inserted. Is fitted to the annular projection 43b on the upper inner surface of the inner cylinder 43. This fitting is loose enough that the opening / outlet member 5 does not fall from the inner cylinder 43, and the opening / outlet member 5 has some vertical movement in the inner cylinder 43. It is allowed. Therefore, the opening / outlet member 5 is not pressed against the packing 44 on the inner surface of the ceiling wall 41 of the cap 4, and the elasticity can be maintained without shrinking the packing.

Attachment of the unsealing prevention member 3 to the cap 4 is performed by press-fitting the four fitting pieces 32 of the unsealing prevention member 3 into the outer cylinder 42 of the cap 4. The fitting between the outer circumferential surface of the fitting piece 32 and the inner circumferential surface of the cap 4 outer cylinder 42 is such that both sides are elastically press-contacted at the time of fitting so that the opening preventing member 3 is not detached from the cap 4, In addition, when the opening and closing member 4 is detached by a user, the size of the fitting piece 32 and the outer cylinder 42 is designed so that the opening preventing member 3 can be removed without requiring a large force. It is.

In this way, the cap 4 in which the opening / outlet member 5 and the opening prevention member 3 are integrally mounted is covered by the head 21 of the container body 2 filled with the contents. (21) The male screw 27 of the outer circumferential surface of the large cylindrical portion 21b and the female screw 43a of the inner surface of the inner cylinder 43 of the cap 4 are screwed together, and the cap 4 is rotated in the screwing direction. The cap 4 is rotated a predetermined time in the screwing direction so that the positioning protrusion 34 of the opening preventing member 3 climbs the ascending protrusion 28a of the proximal end 21c of the head 21 of the container body 2. When the rotational limit regulating projection 28b is brought into contact with the rotational limit regulating projection 28b, the positioning projection 34 is no longer able to rotate in the screwing direction, and the positioning projection 34 is positioned between the climbing projection 28a and the rotational limit regulating projection 28b. The cap 4 is held and held in the crystal recessed portion 28c, and the cap 4 is held and held in a state in which the screw 4 cannot be rotated in the unscrewing direction with a predetermined weak force, and the inner cylinder of the opening / outlet member ( 56 The lower cutting blade 57 does not contact the sealing film 24 at the upper end of the head 21 of the container body 2, and the sealing film 24 is held and held in a sealed state. The cap 4 in this state cannot be rotated in the screwing direction, but in the semi-screwing direction, the positioning protrusion 34 climbs the curved surface of the ascending protrusion 28 (a) by a strong force. It is possible to rotate.

As described above, the container 1 of the present embodiment is a cap in which the opening-outlet member 5 and the opening prevention member 3 are integrally attached to the head portion 21 of the unopened container body 2. (4) can be provided for distribution, exhibition, etc. in the assembled state. Therefore, by removing the cap 4 with which the unsealing prevention member 3 was attached or with the unsealing prevention member 3 integrated, and confirming that the sealing film 24 is not opened, the container main body ( It can be easily seen that 2) is not in use.

<Opened container 1>

7, the container 1 in an opened state is shown. Fig. 7 (a) is a partial enlarged longitudinal sectional view (an elliptical long axis side longitudinal cross-sectional view from the center line, an elliptic short axis side longitudinal cross-sectional view on the right side), and Fig. 7 (b) is a partial enlarged view of the climb-up rotation limit regulating portion 28. Fig. 8 (a) is a plan view, Fig. 8 (b) is a front view, and Fig. 8 (c) is a side view.

In order to open and use the container 1 of the unused state shown in FIG. 1, FIG. 3, the cap 4 with which the opening-outlet member 5 and the unsealing prevention member 3 were integrally attached is first attached. ) Is rotated in the unscrewing direction and removed from the head 21 of the container body 2. Next, after the tear prevention member 3 is removed from the cap 4 in which the tear opening-outlet member 5 and the tear prevention member 3 are integrally attached, the tear opening-outlet member 5 is integrated. The cap 4 mounted as an enemy is again put on the head 21 of the container body 2, and the male screw 27 on the outer circumferential surface of the head 21 large cylindrical portion 21b and the inner cylinder 43 of the cap 4 are mounted. The internal thread 43a is engaged to rotate the cap 4 in the screwing direction. At that time, the cap 4 moves to the body portion 23 side of the container body 2 by the screwing, but since the opening preventing member 3 is removed, the cap 4 can be rotated more by that amount. Also, the moving distance to the body portion 23 side becomes large. With such an axial movement of the cap 4 to the trunk portion 23 side, the opening and dispensing member 5 held and held in the inner cylinder 43 of the cap 4 also moves axially, The cutting blade 57 of the lower part of the inner cylinder 56 of the opening-outlet member 5 contacts the sealing film 24 of the tip of the container main body 2 head 21, and the opening-outlet member ( 5) The longitudinal ribs 26 provided on the outer circumferential surface of the container main body 2 head 21, the small cylindrical portion 21a enter a vertical groove 54d between adjacent axial protrusions 54c on the inner circumferential surface of the outer cylinder 54. Fit in. When the cap 4 is further rotated, the longitudinal ribs 26 are in sliding contact with the longitudinal grooves 54 between the adjacent axial protrusions 54c, and the opening / outlet member 5 is added in the axial direction. The cutting blades 57 formed of three mountain cutting blade portions 57a to 57c formed at the lower portion of the inner cylinder 56 are pressed to the outer periphery of the sealing film 24 to form a cut line. The line is widened to form a final cutline in the range of 280 degrees. The sealing film inside the cutline is pressed downward by the pressing ribs formed on the inner surfaces of the cutting blade portions 57a and 57c, while the pressing rib enters between the cutting blade portions 57a and 57c and the sealing film inside the cutline. A gap is formed between them, the contact resistance of the inner surface of the cutting blade 57 is reduced, and the force required for pressing is reduced.

In the sealing film 24 which the range of 280 degree was cut by the cutting blade 57, the remaining 80 degree part corresponded to the flat surface 58 in which the cutting blade 57 is not formed is left uncut as a connection part, The portions other than the connecting portion are further pushed down by the flat portion 58, and are hung down from the connecting portion by the outer circumferential surface of the flat portion 58, and the container body 2 head 21 It is held in the state of being pressed down on the inner circumference of the car. Thus, when the cutting blade 57 opens the sealing film 24 of the head part 21 upper end, and forms the opening hole, the ring-shaped gap 55 of the opening-outlet member 5 cylindrical part 53 is formed. The annular sealing portion provided on the ceiling surface of the c) and the annular sealing surface around the opening hole abut, and in that state, the engaging surface 54f of the upper portion of the engaging projection 54e of the outer cylinder 54 is the container body. (2) The opening-outlet member 5 is engaged with the lower surface of the tip ring-shaped protruding tank 25 of the head 21 in a state where it is prevented from falling out with respect to the head 21 of the container body 2. The opening-out-outlet member 5 is stopped, and the ejection-outlet 52 communicates with the opening hole and the inside of the head 21, and then functions as the ejection-outlet member of the container main body 2 later. do. When the cap 4 is further rotated in the screwing direction in this state, the packing 44 on the inner surface of the cap 4 ceiling wall 41 is press-contacted against the ceiling wall 51 of the opening / outlet member 5. And the spout 52 is sealed by the packing 44, and the positioning projection 45 of the cap 4 is the climbing projection 28a of the base portion 21c of the head of the container body 2, 21c. ) Is positioned in the positioning recess 28c between the rotation limit regulating projection 28b, and the cap 4 can be rotated not only in the screwing direction but also in the screwing direction with a predetermined weak force. It is held and maintained without it.

In order to use the contents in the container main body 2 after the formation of the opening hole, the cap 4 is strongly rotated in the unscrewing direction so that the engagement of the positioning protrusion 45 and the climbing protrusion 28a is at least one of them. It removes by elastic deformation of the container, and removes it from the head part 21 of the container main body 2 by continuing rotation to a screw loosening direction.

The container body 2 used after opening is that the opening prevention member 3 is removed, and after removing the cap 4, the opening / outlet member 5 is the container main body 2 head ( It is possible to confirm easily from the thing stopped by 21).

The container with the opening means of the present invention utilizes the rotation of the cap at the time of screwing in the formation of the opening hole, but the cylindrical member including the opening means is prevented from rotating relative to the container body head with the opening portion formed therein, Or, since at least it does not actively rotate, a relatively large pressing force from the cutting edge acts on the periphery of the openable portion, but at least a large rotational force does not work. Therefore, it is possible to apply to the container of the material with high flexibility and flexibility, the container with comparatively weak strength, the container which needs to make small opening hole, etc. For example, it can be used suitably as a tube container of the squeeze type of various cosmetics. The container with the opening means of the present invention can be applied to a cap type for opening and closing by screwing and to a cap type for opening and closing a lid supported by a hinge.
