Description

  The present invention relates to a plastic container mainly filled with fresh cream, gum syrup, jelly, or other food, and more particularly to a plastic container that can be easily opened and the contents can be prevented from being scattered at the time of opening.

  As a container for stuffing fresh cream for coffee, gum syrup, or foods such as jelly, pudding, and tofu, a lid lid made of resin is firmly fixed to the circumferential collar of the top of the container in consideration of hygiene during storage Sealed plastic containers are generally widely used. This type of plastic container is made of an aluminum or synthetic resin top lid, which is made of a thermoplastic resin such as polypropylene, the container body is filled with food, and the top opening of the container body is made into a thin sheet. Sealed. In particular, in a conventional plastic container, a knob for making it easy to peel off the upper lid is provided on the upper edge of the container body or a part of the upper lid. And according to that kind of plastic container, an upper cover can be peeled from a container main body by picking the knob | pick part at the time of opening, and pulling up an upper cover inside.

  Conventionally, as in Patent Document 1 and Patent Document 2, in order to prevent scattering of the contents at the time of opening, the upper surface opening of the container body is sealed with an upper lid, and a projecting piece for drilling is formed on a part of the upper lid. And the handle is bent so that the upper lid can be perforated by the protruding piece on the upper surface opening of the container body.

  As shown in FIG. 3, the conventional small container has a fixing part (hereinafter referred to as a sealing part) 6 for sealing the contents inside the folding part 4. When the lid 3 was opened, the contents 2 were scattered due to the difference between the sealed internal pressure and the external pressure in the small container. Further, the lid peeling prevention sealing portion 7 attached to the tip of the knob is designed to prevent the lid from being peeled off by an erroneous operation.

  In order to prevent scattering of the contents at the time of opening, as shown in Patent Document 1 and Patent Document 2, a part in which an exfoliation piece for peeling is provided on an upper lid has been invented. When a small container is packed in a bag or in a cardboard box for transport or storage, a peeling piece of a container may open a hole in the top lid of another container that is in contact with it, and it is stored for a long time. There is a problem that hygiene condition is deteriorated or cannot be performed.

  Therefore, the object of the present invention has been made by paying attention to the above-mentioned two problems, and prevents the contents from being scattered at the time of opening, and is used in a bag or a cardboard box packed with a small container containing the contents. The present invention relates to a small container in which the lid of other small containers is not damaged even when packed and transported or stored.

  As described in claim 1, the small container of the present invention has a lid that closes the upper end opening of the container body, and forms a spout for the contents in the container body. The container main body and the sealing part of the lid are provided on the outer edge part from the folding part in the vicinity of.

  In addition, as described in claim 2, in a container stuffed with fresh food for coffee or gum syrup, or foods such as jelly, pudding, tofu, a lid for closing the upper end opening of the container body, The container body is provided with a spout for the contents, and a sealing portion for fixing and sealing the container body and the lid along the shape of the container body is provided around the outer side of the folding portion in the vicinity of the spout of the container body. It is characterized by that.

  According to the present invention, it is possible to prevent the contents from being scattered at the time of opening only by changing the position of the sealing part 6 for sealing the contents to the outer edge part from the folding part 4. In addition, since there are no projecting pieces for piercing, the lids of other small containers may be damaged when transporting or storing small containers containing the contents packed in a cardboard box. Can be stored for a long time with good hygiene.

  Furthermore, in the present invention, the sealing part 7 for preventing lid peeling is not necessary, and the sealing part attaching process can be reduced.

  Hereinafter, the small container of the present invention will be described with reference to the accompanying drawings, taking as an example a small container containing a cream used when drinking coffee or tea.

  An overall view of the small container 1 is shown in FIG. 1 is a small container main body, 2 is a content, 3 is a lid, 4 is a folding part near the spout, and 5 is a knob.

  FIG. 2 shows an enlarged view of the knob portion of the small container of the present invention. Reference numeral 6 denotes a sealing portion for sealing the contents, and the sealing portion 6 is formed on the outer edge of the folding portion 4 of the knob.

  When the lid 3 is opened, the sealed state is opened at the moment when the folding part 4 is bent and separated. At this time, since some air flows into the small container from the cut-in folding part 4, the difference between the internal pressure and the external pressure of the small container is eliminated, so that the contents are not scattered.

  Moreover, the process of providing the protruding pieces as shown in Patent Document 1 and Patent Document 2 and the process of attaching the lid peeling prevention sealing portion 7 shown in FIG. 3 are not required, and the manufacturing process can be simplified.

  The present invention can be applied to all small food containers currently used, and can be applied to all liquid and fluid small containers other than foods such as cosmetics and medicines.
