Description

  The present invention relates to a portion container filled with coffee milk, gum syrup and the like.

  Conventional potion containers containing milk, gum syrup, food jam, etc. for tea and coffee are made of a thermoplastic resin container such as polypropylene, and the top opening is made of a sheet-like lid made of aluminum or synthetic resin. A tongue piece is provided to make it easy to peel off while being sealed with a body, and when opening, this tongue piece is bent, and a sheet-like lid is pulled up and peeled off to make it easy to open. Yes.

  However, in such a portion container, when the tongue piece is folded and the sheet-like lid is pulled up inward to open, the filling such as coffee milk or gum syrup is excessive. There were problems of splashing outside, sticking to hands and clothes, and spilling around the table.

  Thus, conventionally, proposals have been made regarding potion containers that prevent fillings such as coffee milk and gum syrup from being blown out at once and scattered. For example, `` a container, a container sealing method, and a container sealing device '' in which a lid that is recessed to the inside of the container body bulges outward to prevent an increase in pressure and prevent contents from blowing out at the time of opening (patent document 1) or a plastic with a double lid provided with a hole in the first lid of the upper surface opening, and a second lid having a peeling portion on the first lid provided with the hole. "Made of liquid" (see Patent Document 2) or "mini-cup type liquid crystal" in which an auxiliary adhesive portion connected to the adhesive portion is added to both sides of the open piece portion and cut portions reaching the container body are provided on both sides of the open piece portion. A substance storage container "(see Patent Document 3) has been proposed.

In the above `` container, container sealing method, and container sealing device '' (see Patent Document 1),
The proposal to suppress the pressure rise of the container body at the time of opening by filling the container body in a decompressed state is merely taking a means to make the internal pressure and the external pressure of the container body the same. The problem that the filling material erupts and scatters with the force applied when the seal lid is peeled off or the opening force has not been solved.

Further, in the “plastic container having a double lid” (see Patent Document 2),
A structure in which a hole is provided in the first lid of the upper surface opening, and a second lid having a peeling portion is provided on the first lid provided with the hole, the peeling portion is added to the structure of the conventional portion container. The second lid must be newly provided, and further requires a double effort to peel off the first lid and the second lid, leaving problems in product cost and convenience .

  Further, in the “mini cup type liquid substance storage container” (see Patent Document 3), an auxiliary adhesive portion connected to the adhesive portion is added to both side positions of the open piece portion, so that the container is provided on both sides of the open piece portion. When providing an auxiliary adhesive part connected to the adhesive part provided around the opening part of the main body and providing cut parts reaching the container main body on both sides of the open piece part, when opening the peeled piece part, The range where the other part of the lid connected to the open piece is peeled off by the auxiliary adhesive part is restricted, and the open piece can be peeled off very easily using the cut part within the limited range connected to the cut part. It is possible to reduce the pressure fluctuation in the container body and prevent the scattering of the liquid substance at the time of opening, but tear the open part inward and cut the cover open part. Some ranges constrained by Only in a state of finished peeled, together with the force of peeling without look good also the degree to slightly improved over conventional, were those born need to consider the disposition of the peeled Hirakihen unit in situ.

  As means for solving the above-mentioned problems, means for bringing the pressure inside the container to the same state as the external pressure at the time of opening and means for reducing the peeling force of the welded portion are conceivable. Since the initial adhesive strength of the welded portion is strong and has a structure in which the area to be peeled covers a wide range, it is necessary to be careful to peel off the filler so that it does not scatter to the outside at the time of opening.

  In order to solve the above problems, when attaching a lid to a container in which a baseball cap is turned upside down, the parts other than the collar are adhered to the circumference, and the collar is attached to the tip of the collar. A “container” (see Patent Document 4) in which a curved adhesive portion and a pressing portion are formed by bending in a direction has been proposed.

  In the above-mentioned “container” (see Patent Document 4), mainly when a lid is opened in a container in which liquid is put, the contents scatter and stain clothes, etc., or force transmission from the finger to the lid is unstable. However, it is a proposal to improve the container so that the contents do not scatter, and to stabilize the transmission of force from the finger to the lid. However, it has a problem in the design and packaging properties of the container in order to commercialize the product, although it occupies an unusual size with respect to the shape of the main body.
