Description

  The present invention relates to a container.

  For example, a bag-like container is known in which, for example, fluid food is stored, and a cylindrical discharge port member is fused and fixed to a flexible bag-like container body (see, for example, Patent Document 1). ).

  In the discharge port member of the container, a cylindrical straw portion suspended from the inside of the container body is integrally connected to a cylindrical mouth portion exposed to the outside of the bag-shaped container body. Moreover, it has the ear | edge part which protruded in plate shape on both sides from the upper part of the outer surface of the straw part, and was heat-welded to the container main body. In addition, a cap is detachably screwed to the mouth. In addition, a sealing material that seals the opening is provided at the tip of the mouth after filling it with fluid food, preventing the contents from leaking out from the mouth even when sterilized under pressure and heat. It is configured to be able to. These sealing materials are formed by a film or the like obtained by laminating a synthetic resin film and a metal foil, and are welded to the front end opening of the mouth portion by means such as heat sealing.

Further, in this type of container, the sealing material is welded after filling the container body from the mouth of stored items such as fluid food.
JP 2001-120240 A

  The conventional container of this type exhibits various excellent effects such as the ability to sterilize the stored items smoothly without any problems as described above, and to prove that the container has not been opened, due to the presence of the sealing material at the mouth. Is. However, since the sealing material is a separate member from the main body, it must be welded in a separate process.

  The present invention has been made in view of the above points, and can smoothly sterilize stored items and the like, simplify the manufacturing process, and as a result, can be manufactured at a low cost, and closes the discharge port when opening. We propose a container in which the lid plate to be fitted can be fitted and housed in the cap and the labor required for opening can be saved as much as possible. At the same time, a container that can express the unusedness of the container is proposed.

  The container of the present invention includes a container body and a discharge port member. The container body preferably has a flexible bag shape, for example, a type in which the peripheral edges of two sheets are fixed by means such as fusion, a so-called gusset type of a box type, or a horizontal triangular prism shape. Various bag-like containers such as a so-called standing pouch type and a thin blow molded container can be used. For such a container body, various materials having flexibility such as a single layer or a laminate of synthetic resin or a laminate of a synthetic resin and a metal thin film layer can be selected. The container body is not limited to the bag-shaped one, and other forms of container bodies such as a tube-type container and a bottle-type container body can be employed.

  The discharge port member is provided at the mouth portion of the container body to discharge the contents in the container body, has a cylindrical main body, and a cover plate from which the discharge port at the upper end of the main body can be cut off Is blocked. A cap made of synthetic resin is screwed onto the main body and has a virgin seal function that breaks when the screw is removed. As an example of the function, a virgin ring is integrally formed on the lower surface of the peripheral wall of the cap via an easily cut connecting portion, and the virgin ring is engaged with the outer periphery of the main body while preventing it from coming out. More specifically, the engaging ridge projecting on the inner surface of the virgin ring is configured to be able to express the unused state by getting over the lower surface of the ridge on the outer periphery of the main body. The container of the present invention includes the case where such a virgin seal function is not provided.

  In addition, a movable protrusion for cutting the thin connecting portion of the cover plate and opening the discharge port is attached to the cap so as to be movable up and down. When the cap is screwed, the movable projection acts so as to get over the fixed projection provided on the lid plate, and when the cap is screwed off, the movable projection engages with the fixed projection to engage the lid plate with the main body. It acts to forcefully rotate it. Therefore, when the cap is screwed, the force for cutting the thin-walled connecting portion of the lid plate works only to a negligible level, and when the cap is screwed, the thin-walled connecting portion is surely cut and the discharge port is opened.

  The fixed projection has an upper surface as the first sliding surface, and the movable projection has the lower surface as the second sliding surface. The first sliding surface is provided in the direction opposite to the screwing rotation direction, and the second sliding surface is provided in the screwing rotation direction. The first sliding surface and the second sliding surface can adopt various forms of surfaces as long as the movable protrusion slides up and the movable protrusion slides up. In general, inclined surfaces can be adopted. In addition, a curved surface or a combination thereof can be adopted as long as the above object can be achieved. The first sliding surface is configured to be positioned on the rotation locus of the second sliding surface when the cap is screwed to the main body, and the second sliding surface is the first sliding when the cap is screwed. Since the second sliding surface slides and rises on the first sliding surface, the movable projection rises and rotates and climbs over the fixed projection. On the contrary, when the cap is screwed off, the first and second sliding surfaces do not come into contact with each other, and the side surfaces of the movable projections press the side surfaces of the fixed projections in the screwing rotation direction. The shearing force is applied to the material and it is cut.

  The initial purpose can be achieved with either a single or a plurality of fixing protrusions, but in consideration of the size of this type of container, the pitch of the screws, etc. Although it is good to provide a protrusion, naturally it is not restricted to this. Similarly, the number of movable protrusions may be singular or plural, and may be the same as or different from the number of fixed protrusions.

  The fixed protrusion may be erected on the peripheral edge of the cover plate. However, when the first engagement tube described later is erected on the cover plate, the fixed protrusion may protrude from the outer surface of the first engagement tube. In any case, it is provided so that it can move integrally with the lid.

  The movable protrusion may be mounted independently on the cap so as to be movable up and down, but a configuration in which the movable protrusion protrudes from a movable ring mounted on the cap so as to move up and down can be preferably employed.

As a first means, a container provided with a discharge port member B in the mouth part 2 of the container body A, the discharge port member B being a cylindrical main body B whose periphery is fixed to the mouth part 2 of the container body A _1, and a cap B ₂ which is screwed to the body B _1, the discharge port 13 closed by cover plate 14 which is connected to the body B ₁ via the thin connection section 15 of the peripheral edge, a top first slide The fixed projection 18 formed on the moving surface f ₁ is provided on the cover plate 14, and the movable projection 43 formed on the lower surface on the second sliding surface is prevented from rotating and can be moved up and down so that the inner periphery of the cap B ₂ And when the cap B ₂ is screwed, the second sliding surface f ₂ slides up the first sliding surface f ₁ so that the movable protrusion 43 gets over the fixed protrusion 18, and the cap B ₂ The fixed projection 18 is configured to prevent the movable projection 43 from rotating when the screw is unscrewed.

As a second means, in the said first means, to maintain the lowered position relative to the cap B ₂ of the movable projection 43, and urged downward the movable projection 43 at all times.

As a third means, in the first means, the movable protrusion 43 is protruded from a movable ring 41 fitted to the upper part of the peripheral wall 20 of the cap B _{2 so} as to be movable up and down with a predetermined width.

The As fourth means, in the said third means, to maintain the lowered position relative to the cap B ₂ of the movable projection 43, the elastic plate that is vertically integrated from the top wall 21 the back surface of the cap B ₂ 26, the upper surface of the movable ring 41 was constantly urged downward.

As a fifth means, in any one of the first means to the fourth means, the first engagement tube 16 erected on the upper surface of the lid plate 14 and the back surface of the top wall 21 of the cap B ₂ The second engagement cylinder 27 that was further suspended was engaged so that it could not be pulled out.

As a sixth means, any one of the first to fifth means is provided with a virgin seal function that breaks when the cap B ₂ is screwed off.

In the container 1 of the present invention, the discharge port 13 at the upper end of the main body B ₁ is closed with the cover plate 14, so that the sterilization treatment of the stored items can be performed smoothly without worrying about the leakage of the stored items. , and the addition, the cover plate because it is formed integrally with the main body B _1, there is an advantage to be simplified compared its manufacturing process with conventional products. Further, the peripheral edge of the cover plate 14 is connected via the thin connection section 15, it is possible to open the discharge port 13 by breaking the thin connection section 15 among the operations of the cap B ₂ to unscrewed, handle The operation is very convenient. Further, when the cap is screwed, the second sliding surface f ₂ of the movable projection 43 slides and rises above the first sliding surface f ₁ of the fixed projection 18 so that the movable projection 43 gets over the fixed projection 18. Since it is configured, the thin connecting portion 15 is hardly burdened, and there is no possibility of causing inconvenience such as damage to the thin broken portion 1 when the cap is screwed.

To maintain the lowered position relative to the cap B ₂ of the movable projection 43, when urged downwardly movable projection 43 at all times, rather than by its own weight when the movable projection 43 rides over the fixing protrusion portions 18, Since the movable protrusion 43 can be forcibly returned to the original position, the restored state can be secured quickly and reliably, and the cutting operation of the cover plate 14 is hindered with the movable protrusion 43 still moving upward. It is possible to prevent inconveniences such as incurring more reliably.

When the movable protrusion 43 is protruded from the movable ring 41 fitted to the upper part of the peripheral wall 20 of the cap B _{2 so} as to be able to move up and down with a predetermined width, the assembly to the cap B ₂ is easy. Assembling is easier when there are multiple 43s.

To maintain the lowered position relative to the cap B ₂ of the movable projection 43, when normally urged downward an upper surface of the movable ring 41 by elastic plate 26 which is vertically integrated from the top wall 21 the back surface of the cap B ₂ is In addition, there is a molding advantage that the elastic plate 26 does not need to be specially formed and assembled, and the position of the movable protrusion 43 or the movable ring 41 is a guide, and the assembly operation is facilitated.

When the first engagement cylinder 16 erected on the upper surface of the lid plate 14 and the second engagement cylinder 27 suspended from the back surface of the top wall 21 of the cap B ₂ are engaged so as not to come out, the lid plate is cut. 14 can be engaged with the cap as it is, so that the trouble of discarding the cover plate 14 again can be saved.

When a virgin seal function is provided that breaks when the cap B ₂ is screwed off, it is possible to know at a glance that the container is not used, thereby improving the reliability of the product. In particular, the cover plate 14 to be ruptured separated by threaded disengagement of cap B _2, it can be reliably prevented separation of inadvertent lid plate 14.
