JP4764218B2 - Overcap container with opening blade - Google Patents

Description

  The present invention relates to a container with an overcap having an opening blade, and is intended to reliably avoid contact and scattering between fingers and contents when the container is opened.

  In recent years, beverages such as coffee and tea have adopted an aseptic filling system that can maintain the taste and flavor of the contents well, and the containers used therefor have a cup-shaped body and their mouths. In general, a film-like sealing sheet is affixed to the portion, and an overcap is attached to the outside in order to protect the sealing sheet.

  This type of container is provided with a straw on the body of the container, and the straw is inserted through a hole formed in the overcap, and the content in the container is sucked by breaking through the sealing sheet at the tip of the straw. I am doing so.

  In addition, recently, since the contents are heated by the warmer, it is difficult to use a straw, and the sealing sheet is opened with a single touch using the pressing piece of the overcap, and the overcap is formed. There has also been proposed a container of a type for drinking contents directly from a drinking mouth (see, for example, Patent Document 1).

By the way, in the case of a container that opens the sealing sheet with a single touch, the contents may be scattered depending on the force applied when pushing the push-down piece, and the push-down piece touched by the fingertip may be immersed in the content. When opening, the fingertip may touch the contents, which is not preferable in terms of hygiene, and a solution has been demanded.
JP 2004-359314 A

  An object of the present invention is to propose a container with a new overcap that can be opened hygienically without scattering the contents.

The present invention has a filling space for storing contents, a container body that holds the filling space in a liquid-tight state with a sealing sheet attached at the mouth, and a sealing sheet that is housed inside the container body. With an overcap fixed to the mouth,
An opening that forms a spout for the contents is provided in the top wall of the overcap, and an opening blade that pushes down the sealing sheet positioned directly below the opening by swinging the pivoting connection portion around the pivot is disposed in this opening. And
The opening blade is a container with an overcap having a basic structure having an opening blade characterized by comprising a blade portion for directly cutting the sealing sheet and an operation piece connected to the end of the blade portion.

The present invention in a container made to the above structure is one where the pivotal connection portion, is integrally connected to the overcap and opened blade.

The operation piece is provided with a stopper that maintains the initial posture of the opening blade in cooperation with the top wall of the overcap.

Furthermore, the blade section, Ri connected to the openings forming the spout may be provided with a window hole for allowing the discharge of the contents of the tilting of the container body remains the initial position, adjacent to the window opening The air introduction hole may be formed.

  When the operation piece of the unsealing blade is pulled up with the pivot connection portion as a fulcrum, the blade portion is swung down and the sealing sheet positioned immediately below is pushed out, and the fingertip does not touch the contents.

  In addition, the blade part can be swung down indirectly with the operation piece, so that the adjustment of the force can be easily adjusted, and not only the contents are scattered by momentum but also the small force is applied by the lever principle. Can be opened.

Hereinafter, the present invention will be described more specifically with reference to the drawings.
1A and 1B are a plan view and a side view showing an embodiment of a container with an overcap according to the present invention, and FIG. 2 is an external perspective view.

  Reference numeral 1 in the figure denotes a synthetic resin container body having a cup shape. The container body 1 has a filling space m for storing contents, and a sealing sheet 2 is adhered to the flange f of the mouth portion 1a, and the filling space m is held in a liquid-tight state by the sealing sheet 2. ing.

Reference numeral 3 denotes an overcap that houses the sealing sheet 2 inside and is detachably fixed to the mouth 1a of the container body 1. The overcap 3 comprises a top wall 3a facing the sealing sheet 2 at a distance, and a peripheral wall 3b integrally connected to the edge of the top wall 3a and surrounding the sealing sheet 2, and the top wall 3a. In the central area, a partition recess 3a ₁ is provided that bisects it in the radial direction.

Further, 4 denotes an opening provided in the partition recesses 3a ₁ of the top panel wall portion 3a, to form a spout with a portion of the opening 4 and the peripheral wall 3b. 5 is an opening blade. The unsealing blade 5 includes a blade portion 5a and an operation piece 5b connected to the end of the blade portion 5a, and can be rotated with a pivotal connection portion 5c formed integrally with the top wall portion 3a as a fulcrum. ing.

Reference numeral 6 denotes a stopper as an example of a notch provided in the operation piece 5b of the opening blade 5. This stopper 6 maintains the opening blade 5 in a horizontal posture by linking to the vertical rib r provided on the rising wall of the partition recess 3a ₁ of the overcap 3. The unsealing blade 5 can also be provided with a clear opening function by being integrally connected to the rising wall of the partition recess 3a ₁ via a connecting piece or the like.

  Further, 7 is a window hole provided in the blade part 5a of the opening blade 5 and connected to an opening forming a drinking mouth, 8 is an air introduction hole also provided in the blade part 5a, and 9 is a container that covers the overcap 3 and covers it. It is a protective cover that is detachably held in the mouth portion 1a of the main body 1.

  In order to open the container, it is caused by placing a finger on the rear end of the operation piece 5b of the opening blade 5. Then, the blade portion 5a is swung down with the pivotal connection portion 5c as a fulcrum as shown in FIG.

  After the sealing sheet 2 is pressed and the container is opened, the opening blade 5 is returned to the initial position (horizontal position) as shown in FIG. 4, and the container is tilted to discharge the contents.

  The unsealing blade 5 may be removed from the overcap 3 when discharging the contents. Even when the window hole 7 and the air introduction hole 8 are not provided, a gap that allows the contents to be discharged is formed between the peripheral wall 3b and the opening blade 5 in order to allow the contents to be discharged. .

  The container with an overcap according to the present invention can open the container without touching the blade part 5a as described above, and the contents do not touch the fingertip during opening.

  Further, since the blade portion 5a is swung down via the operation piece 5b, it is possible to adjust the amount of force, and the contents are not scattered with momentum.

  The blade portion 5a can be fixed in a posture as shown in FIG. 3, and in this case, a stopper is provided separately.

  It is possible to provide a container with an overcap that is hygienic and that does not come into contact with the contents without causing the contents to splash when the container is opened using the opening blade.

It is the figure which showed embodiment of the container with an overcap according to this invention, (a) is a top view, (b) is a side view. It is an external appearance perspective view of the container shown in FIG. It is explanatory drawing of the opening procedure of the container shown in FIG. It is the figure which showed the extraction | pouring situation of the contents.
