The bulge 4 has a first portion 41 at the bottom, a third portion 43 at the top, and a second portion 42 between the first portion 41 and the third portion 43.
The first portion 41 is a portion facing the frozen dessert 13 in the state of the container 10 containing the frozen dessert. The first portion 41 has a tip shape. As shown in FIG. 5B, the horizontal cross-sectional shape of the first portion 41 is a non-circular shape including an arc. The non-circular shape including the arc is not particularly limited, and examples thereof include an elliptical shape, a land track shape (a shape in which two parallel straight lines are connected by two semi-arcs), and a shape similar thereto.
The second portion 42 smoothly connects the first portion 41 and the third portion 43.

The third portion 43 includes two proximity portions 431 and 431 adjacent to the upper portion of the inner surface 26 of the container body 2, and separation portions 432 and 432 arranged between the two proximity portions 431 and 431 in a plan view.

As shown in FIGS. 5 and 6, a total of four ribs 38 are provided in a region facing the inner surface 26 of the container body 2 in the vicinity of both ends in the circumferential direction of the proximity portion 431. The rib 38 projects outward in a plan view and extends in the vertical direction. In the state where the bulging member 3 is arranged on the container body 2, the proximity portion 431 of the third portion 43 does not contact the inner surface 26 of the container body 2, and the rib 38 substantially touches the inner surface 26 of the container body 2. Make line contact.

The flange portion 33 is divided into a mounted portion 331 and a non-mounted portion 332 corresponding to the proximity portion 431 and the separation portion 432 of the third portion 43 in a plan view. In the plan view, the mounted portion 331, the non-mounted portion 332, the mounted portion 331, and the non-mounted portion 332 are arranged in this order in the circumferential direction. The non-mounting portion 332 extends in an arc shape that is convex inward in the radial direction in a plan view, and constitutes an inward concave edge portion 36. That is, a plurality of inward concave edge portions 36 (two in the present embodiment) are formed on the bulging member 3. The inwardly concave edge portion 36 extends in an arc shape in a plan view.

As shown in FIG. 2, in a plan view, at least three points (P1, P2, P3) of the outer edge of the flange portion 33 of the bulging member 3 (specifically, the outer edge of the mounting portion 331) are on the virtual circle C1. It is configured to be located. In FIG. 2, three points (P1, P2, P3) are indicated by white circles (◯). Only one virtual circle C1 passing through three points (P1, P2, P3) can be drawn. The virtual circle C1 substantially coincides with the outer edge of the flange portion 24 of the container body 2, or is arranged on the flange portion 24 of the container body 2. Therefore, the bulging member 3 (bulging portion 4) is arranged in the internal space 25 of the container body 2 by placing (or locking) the flange portion 33 of the bulging member 3 on the flange portion 24 of the container body 2. Can be made to.

In a plan view with the bulging member 3 arranged in the container body 2, a plurality of finger insertion regions 6 into which fingers can be inserted are formed between the opening 21 of the container body 2 and the bulging member 3. .. The finger insertion region 6 is formed by the opening 21 of the container body 2 and the inward concave edge portion 36 of the bulging member 3.

It is formed. Since the bulging portion 4 of the swelling member 3 exists, when the swelling member 3 is arranged in the container body 2, a concave recess 14 (see FIG. 7C) may be formed in the upper part of the frozen dessert 13. can. As the frozen dessert 13, for example, conventionally known frozen desserts such as sherbet and ice cream can be exemplified.

[Sheet constituting the bulging member 3]
The tensile elastic modulus of the sheet (hereinafter, also simply referred to as sheet A) constituting the bulging member 3 is less than 1200 MPa, preferably 900 MPa or more and less than 1200 MPa, and particularly preferably 1000 MPa or more and 1100 MPa or less. When the tensile elastic modulus is less than 1200 MPa, the bulging member 3 can be easily deformed. Further, when the tensile elastic modulus is 900 MPa or more, it is possible to prevent the swelling member 3 from being deformed too much and making it difficult to pull out the swelling member from the frozen dessert in a state where the frozen dessert is contained.

In the present invention, the tensile elastic modulus is measured according to JIS K7127. If necessary, JIS K7161-1 (when the thickness is 1 mm or less) or JIS K7161-2 (when the thickness is more than 1 mm) is referred to.
Specifically, the tensile elastic modulus is obtained as follows. A dumbbell type test piece (test piece type 1B) is prepared from a sheet state having a predetermined thickness. Using this test piece, a tensile test is performed under the conditions of a line-to-line distance of 50 mm and a tensile speed of 1 mm / min. The tensile elastic modulus is obtained from the slope of the stress-strain curve measured by the tensile test. Here, the tensile elastic modulus is calculated by taking the average of 10 points in the MD (sheet flow direction) direction, taking the average of 10 points in the TD direction (seat width direction), and further taking the average of the MD direction and the TD direction. It is an average value.

The bulging member 3 can be thermoformed by, for example, a conventionally known sheet forming method. The thickness of the sheet A is preferably 0.5 mm or more and 2.0 mm or less. The sheet constituting the bulging member 3 may be a single layer or a multi-layered sheet.

The material of the sheet A constituting the bulging member 3 is not particularly limited as long as it has a tensile elastic modulus in the above range, but from the viewpoint of cost and hardness, polystyrene-based resin, polyethylene-based resin, polypropylene-based polyolefin, etc. A based resin can be preferably used. Among them, it is preferable to use a resin composition containing 50% by mass or more of a polypropylene-based resin.

Specific examples of the polypropylene-based resin include propylene homopolymers and copolymers with other olefins copolymerizable with propylene. By using a copolymer, the impact resistance, especially the cold impact resistance at a low temperature, can be improved, and the above-mentioned tensile elastic modulus can be adjusted.

The above-mentioned copolymer may be a random copolymer, a block copolymer, a binary copolymer, or a ternary or higher copolymer. May be good. Only one kind of the polypropylene resin may be used, or two or more kinds may be used in combination. In the copolymer of the above propylene and another olefin copolymerizable with propylene, the content of the propylene monomer is 50% by mass or more, preferably 80 in 100% by mass of the polymerizable polymerization component used for the copolymerization. It is mass% or more.

Examples of other olefins copolymerizable with the above propylene include ethylene and α-olefins. The α-olefin preferably has 4 to 10 carbon atoms. Examples of the α-olefin include 1-butene, isobutylene, 1-pentene, 3-methyl-1-butene, 1-hexene, 3,4-dimethyl-1-butene, 1-hexene and 3-methyl-1-hexene. And so on.

Further, the sheet A may be used in combination (blend) with the above-mentioned polypropylene-based resin and polyethylene-based resin. Examples of the polyethylene-based resin include low-density polyethylene, medium-density polyethylene, high-density polyethylene, and ethylene-propylene rubber (EPR). As a result, the impact resistance, especially the cold impact resistance at a low temperature, can be improved, and the above-mentioned tensile elastic modulus can be adjusted. Even in this case, the content of the propylene monomer is 50% by mass or more, preferably 80% by mass or more. The content of propylene monomer referred to here is the total amount of all propylene monomer units in the resin composition.

Further, the sheet A may be further combined (blended) with a thermoplastic elastomer in order to improve the impact resistance. Examples of the thermoplastic elastomer include styrene-based thermoplastic elastomers such as styrene-butadiene-styrene copolymer (SBS) and styrene-ethylene butylene-styrene copolymer (SEBS), and ethylene-propylene rubber (EPR). Olefin-based thermoplastic elastomer, and the like. Even in this case, the content of the propylene monomer in the resin composition is 50% by mass or more, preferably 80% by mass or more.

The tensile elastic modulus of the sheet A can be appropriately set by selecting the polypropylene-based resin described above and, if necessary, changing the amount of the polyethylene-based resin or thermoplastic elastomer used in combination therewith. As an example of a material composition having a tensile elasticity of 900 MPa or more and less than 1200 MPa, an ethylene resin (or an ethylene resin (or a polypropylene monomer unit in a block copolymer) has a mass ratio of 70 parts by mass to 90 parts by mass. Alternatively, the composition of the ethylene monomer unit) is 30 parts by mass to 10 parts by mass, but the composition is not limited thereto.

[Sheet constituting the container body 2]
The tensile elastic modulus of the sheet (hereinafter, also simply referred to as sheet B) constituting the container body 2 is larger than that of the sheet A described above. Specifically, the difference in tensile elastic modulus between the sheet A and the sheet B is zero or more. The value of the tensile elastic modulus of the sheet B is preferably 900 MPa or more and 1400 MPa or less, and more preferably 1200 MPa or more and 1300 MPa or less. By making the tensile elastic modulus of the container body 2 larger than the tensile elastic modulus of the swelling member 3, the container body 2 becomes harder than the swelling member 3, so that the swelling member 3 is in a state where the frozen dessert is contained. Can be easily deformed to pull out the swelling member 3 from the frozen dessert.

The material constituting the sheet B is the same as that of the sheet A except that the tensile elastic modulus is different, and thus the description thereof will be omitted. Further, the adjustment of the tensile elastic modulus of the sheet B is the same as that of the sheet A, and the detailed description thereof will be omitted. It can be adjusted (increasing the tensile elastic modulus) by lowering the mass ratio of the ethylene resin to the monomer unit).

[Separation operation]
The operation of separating the frozen dessert 13 and the swelling member 3 of the frozen dessert container 10 of the present embodiment will be described with reference to FIGS. 7 and 8. 7 (A) to 7 (C) are vertical cross-sectional views (corresponding to FIGS. 4 and 3) schematically showing the process of separating the frozen dessert and the swelling member in the container containing the frozen dessert of FIG. 8 (A) to 8 (C) are plan views (corresponding to FIG. 2) schematically showing the process of separating the frozen dessert and the swelling member in the container containing the frozen dessert of FIG.

As shown in FIGS. 7A and 8A, in the container 10 containing frozen dessert, the outer lid member 5 attached to the opening 21 of the container body 2 is removed from the opening 21 of the container body 2. As shown in FIGS. 7 (B) and 8 (B), the fingers F and F are inserted into the two finger insertion regions 6 and 6, respectively, from above.

As shown in FIGS. 7 (C) and 8 (C), the inward concave edge portion 36 of the bulging member 3 is sandwiched between two fingers F and F, whereby the bulging member 3 is gripped. Then, the bulging member 3 is rotated in an arbitrary direction. Here, the horizontal cross-sectional shape of the bulging portion 4 is a non-circular shape including an arc. Further, the horizontal cross-sectional shape of the recess 14 formed under the frozen dessert 13 formed by the bulging portion 4 is also a non-circular shape following the horizontal cross-sectional shape of the bulging portion 4. Due to the non-circular shape of the bulge 4 and the dent 14, the rotation of the bulge member 3 is hindered by the dent 14. However, when the bulging member 3 is further rotated, the outer surface of the bulging portion 4 is quickly separated from the inner surface of the recess 14. Further, since the bulging member 3 is restricted from moving downward, it moves upward where movement is permitted. In this way, the bulging member 3 can be easily gripped by the finger F, and the bulging member 3 gripped by the finger F can be easily separated from the recess 14 of the frozen dessert 13.

At this time, the test results of measuring the tensile elastic modulus of the sheet A constituting the bulging member 3 and the sheet B constituting the container body 2 are shown below. Here, the measurement conditions of the tensile elastic modulus are based on the above-mentioned measurement conditions. The thickness of the sheet A is 1.10 mm, and the thickness of the sheet B is 1.75 mm. The temperature of the test room is 23 ° C. Sheet A is a block copolymer of polypropylene-based resin and polyethylene-based resin in which melting point peaks are clearly observed at both the main peak of 165 ° C. and the sub-peak of 127 ° C. as the melting points by differential thermal analysis. Sheet B is a block copolymer of a polypropylene-based resin and a polyethylene-based resin in which melting points are observed at a main peak of 165 ° C. and a sub-peak of 127 ° C. (shoulder) as melting points by differential thermal analysis.
Tensile strength of sheet A (average of 10 points in MD direction, average of 10 points in TD direction, average of MD direction and TD direction): 1070 MPa
Tensile strength of sheet B (average of 10 points in MD direction, average of 10 points in TD direction, average of MD direction and TD direction): 1230 MPa

A plurality of finger insertion regions 6 into which the finger F can be inserted are provided at positions between the two. Further, the tensile elastic modulus of the sheet constituting the bulging member 3 is less than 1200 MPa. As described above, since the swelling member 3 is soft, the swelling member 3 can be easily deformed when the swelling member 3 is pulled out from the frozen dessert 13 in the state where the frozen dessert 13 is housed.

Further, in the frozen dessert storage container 1 of the first embodiment, the tensile elastic modulus of the sheet constituting the swelling member 3 is smaller than the tensile elastic modulus of the sheet constituting the container body 2. As described above, since the swelling member 3 is soft and the container body 2 is hard, when the swelling member 3 is pulled out from the frozen dessert 13 in the state where the frozen dessert 13 is housed, the swelling member 3 is deformed and swells from the container body 2. It is possible to facilitate the work of pulling out the ejecting member 3.

According to the swelling member 3 of the first embodiment, a part or all of the effect of the frozen dessert storage container 1 of the above-mentioned first embodiment is exhibited.
