Abstract

<P>PROBLEM TO BE SOLVED: To provide an outlet cap free from splashing of a content when the outlet is opened. <P>SOLUTION: The outlet cap consists of a cap body (1) fixed and held on a mouth of a container, a sealing wall (2) integrally formed with the cap body (1) and torn off along a line (L) expected to break to form an outlet opening, and a lid (4) combined with the cap body (1) for keeping the outlet opening liquid-tight. One or more dents (6) for reducing the thickness of the sealing wall (2) to gradually guide its opening are provided on a front or rear face of the wall (2). <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a pouring cap of a type in which a sealing plug is torn and opened through a pull ring, and it is intended to surely avoid the splashing of contents that tends to occur at the initial stage of tearing of the sealing plug. Is.

  In recent years, an extraction cap that forms an extraction opening by tearing the sealing wall along the stopper to be broken can prevent unauthorized opening, and can maintain a highly sealed container. It is frequently used in containers for soy sauce, beverages, etc. (see, for example, Patent Document 1).

JP 10-167308 A

  By the way, when this kind of pouring cap is opened in a state where the inside of the container is decompressed, it has often been found that the contents jump off due to a rapid inflow of air into the container.

  The subject of this invention exists in the place which proposes the novel extraction cap which can prevent the splash of the content at the time of the above opening.

The present invention includes a cap body fixedly held at a mouth portion of a container, a sealing wall that is integrally formed with the cap body and that forms a pouring opening by tearing along a planned fracture line, and the pouring opening that fits the cap body A pouring cap comprising a lid that holds the liquid in a liquid-tight state,
The sealing wall has at least one of a front surface and a back surface, and has one or more recesses for reducing the thickness of the sealing wall and inducing stepwise opening. In addition, it is preferable that the concave portion is arranged so as to intersect in the tearing direction of the sealing plug.

  If a recess for reducing the thickness of the sealing is provided on the front or back surface of the sealing wall, the tearing force is temporarily reduced at that portion, and at this time, a small size opening through which air gradually flows. However, a rapid inflow of air does not occur even if the opening area is enlarged by subsequent tearing.

Hereinafter, the present invention will be described more specifically with reference to the drawings.
1 (a) and 1 (b) show an embodiment of a pouring cap according to the present invention.

  In the figure, 1 is a cap body fixedly held at the mouth of the container, 2 is a sealing wall that forms a pouring opening by tearing along the cutting line L, 3 is integrally connected to the sealing wall 2 and the sealing plug 2 A pull ring 4 for tearing is attached to the cap body 1 through a hinge h so as to be swingable, and is a lid body that fits the cap body 1 and holds the pouring opening in a liquid-tight state.

  Reference numeral 5 denotes a notch serving as a base point for tearing the sealing wall 2, and 6 denotes a recess provided on the back surface of the sealing wall 2. The recess 6 is illustrated as an example of a groove-like recess disposed so as to cross the direction (X in the figure) for tearing the sealing wall 2, and stepwise opening of the recess 6 is induced by the recess 6.

  When the sealing wall 2 is torn to the recess 6, the force required to tear the sealing wall 2 is once weakened here, but air flows into the container from the small opening formed at this time. Therefore, even if the opening area is enlarged by subsequent tearing, the air does not flow rapidly and the splash of the contents is avoided.

  The planar shape of the sealing wall 2 can be variously changed depending on the type of contents filled in the container and is not particularly limited in the present invention. For example, the shape as shown in FIGS. In the case of having AA view), it is preferable to provide the recess 6 at the boundary where the shape changes rapidly.

  Although the hinge type pouring cap is shown in FIG. 1 above, the lid 4 may be of a type that can be attached and detached with screws, and this point is not limited.

  Since the planned cutting line L of the sealing wall 2 can be formed by thinning the portion, the stepwise opening may be induced by changing the degree of thinning.

  It is possible to provide a pouring cap that prevents the contents from splashing when opened.

(A) (b) is the figure which showed embodiment of the extraction | pouring cap according to this invention. (A) (b) is the figure which showed the planar shape of the sealing wall.
